Background

The mainstream wind power generator widely applied in the world still uses the principle of a horizontal shaft rotor windmill, and the wind power is captured only by the limited wind receiving surface of a rotor blade and the wind sweeping surface of an impeller. In order to improve the power generation power of the wind driven generator, the effective diameter of the windmill blade is only increased, so that the limited wind power can be increased, but a series of contradictions which are difficult to solve are brought along: (1) along with the increase of the diameter of the windmill blade, the linear speed and the wind speed ratio at the blade tip of the windmill blade are increased, and the windmill blade is in the extreme working state for a long time; (2) from the overall structure, all the weights of the huge rotating wind wheel and the generator rotor of the wind driven generator are concentrated on a horizontal shaft in high altitude, so that an unreasonable physical structure of light weight at the head and feet is formed, a series of technical bottlenecks which are difficult to break through are brought to the design and manufacture of the existing wind driven generator, and the single machine capacity of the traditional wind driven generator cannot be made large and has been put to the public; (3) because of the inherent defects of the physical structure of the traditional wind driven generator, serious noise pollution is inevitably generated in the operation process, various ecological hazards of a three-dimensional space are easily caused by the high-speed rotation of a huge fan blade, and the comprehensive social and economic benefits are greatly reduced.

Detailed Description

The invention relates to an integral structure of a wind driven generator with water float sails, which comprises five systems of a water pool or an annular water tank, a water float running system, a positioning system, a braking system, a generator system and the like. The structure, technical characteristics and working principle of the above-mentioned system of the wind generator with water float sails are explained in detail with reference to the attached drawings:

annular water tank of wind driven generator with water float sails

The water pool or the annular water tank of the wind driven generator with the water float sails is a basic structure of the wind driven generator with the water float sails, and liquid enough for ensuring that the water float running system can float to a normal working water level is filled in the water pool or the annular water tank. The liquid in the water pool or the annular water tank can be ordinary water or other low-viscosity anti-freezing chemical liquid which is pollution-free and meets the environmental protection requirement.

As shown in fig. 4, 5, 6, 8 and 10, the annular water tank can be built on the ground, on the top of a building or float on the water surface, and an annular groove-shaped structure is mainly formed by the inner ring water retaining wall 17, the outer ring water retaining wall 18 and the annular water tank bottom 19. The top sealing cover of the annular water tank is mainly arranged according to the requirement of a positioning system, for example, in the embodiment shown in fig. 10, an annular water tank inner ring top sealing cover 20 and an annular water tank outer ring top sealing cover 21 are respectively arranged on the upper parts of an inner ring water retaining wall 17 and an outer ring water retaining wall 18 of the annular water tank; in the embodiment shown in fig. 6, the annular water tank outer ring seal top cover 21 is only arranged on the upper part of the annular water tank outer ring water retaining wall 18.

In addition, in some applications, the inner ring water retaining wall 17 of the annular water tank can be omitted, the water tank is directly used for replacing the annular water tank, but the mode is not favorable for controlling the water level, and when the water storage mode of the water tank is adopted, the operation system is difficult to introduce water in the water tank into the water turbine guide pipe due to the fact that the operation system is not convenient to implement flexible positioning modes such as magnetic positioning, limit wheel limiting and the like, so that the shaft positioning mode is generally adopted and the electromechanical integrated permanent magnet direct drive generator is matched with the positioning mode.

As shown in fig. 10, in the embodiment of the wind turbine generator with water surface floating type water float sails applied to the water surface, the annular water tank is a water surface floating type annular water tank with an inner cavity structure, and the inner cavity of the water surface floating type annular water tank may be filled with the filler 22 or not. The filler 22 may be light rigid polyurethane foam, or may be other materials that are inexpensive, have a low specific gravity, a high strength, a low water absorption, and a good compression resistance.

As shown in fig. 6, 8 and 10, a series of overflow pipes 40 are uniformly distributed on the inner ring water retaining wall 17 of the annular water tank. In practice, the overflow pipes 40 may be provided on the outer-ring water-retaining wall 18 separately or simultaneously. Through the overflow pipes 40, when the liquid level in the annular water tank is too high, the liquid in the annular water tank can overflow, so that the situation that the liquid level is too high to affect the normal operation of a positioning system, a generator system and the like of the wind driven generator with the water float sails is avoided.

In order to regulate and control the water level in the annular water tank, a series of water inlet and outlet pipelines 41 which are uniformly distributed are arranged on the annular water tank inner ring water retaining wall 17, and a water inlet and outlet valve 42 and a water inlet and outlet bidirectional water pump 43 are arranged on the water inlet and outlet pipelines 41.

The water inlet and outlet pipes 41 arranged on the inner ring water retaining wall 17 can also be simultaneously or separately arranged on the outer ring water retaining wall 18 of the annular water tank. During specific implementation, the water inlet and outlet pipeline 41 can be arranged at other parts of the annular water tank independently or simultaneously according to specific conditions, such as the bottom 19 of the annular water tank, and the water inlet and outlet pipeline 41 can be extended into the annular water tank along the top of the annular water tank on the premise of not influencing the normal operation of the water floating operation system.

The water inlet and outlet valve 42 arranged on the water inlet and outlet pipeline 41 can be manual, electric or dual-mode. The water inlet and outlet pipe 41 is provided with a water inlet and outlet valve 42 and a water inlet and outlet bidirectional water pump 43, and is also a device for implementing grounding brake on the water floating running system. As will be seen from the description below, the inlet and outlet conduits 41 serve as inlet conduits when water is required to be added and as outlet conduits when braking is required.

As shown in FIG. 5, a certain water passage space 30 is formed between the water floating running system and the inner ring water retaining wall 17 and the outer ring water retaining wall 18 of the annular water tank.

The water level line 37 in fig. 6 and 8 represents the water level line of the circular water tank in a static state; when the water floating running system is in a rotating running state, a water level line 38 is present in the annular water tank in a moving state with a low inner diameter and a high outer diameter as shown in fig. 6.

Water float running system of wind driven generator with water float sails

In the embodiment shown in fig. 1-13, the water float running system of the wind power generator with water float sails is composed of a water float running platform 8 and a plurality of ram-jet wing type sails 16 arranged on the water float running platform 8.

The water float running system floats on the water surface in a water pool or an annular water tank, and is driven by wind power to drive the water float running platform 8 to do horizontal circular motion by the ram-jet airfoil sails 16 uniformly distributed on the water float running platform 8 for catching wind, is an important carrier for the water float sail wind power generator to realize wind-power energy conversion, and is one of the core systems of the invention.

The water float running platform 8 is a floating body with a circular ring-shaped inner cavity structure, and is a basic platform carrier which forms a water float running system and bears ram jet type wing sails 16 and the like. As shown in fig. 5 and 7, a series of uniformly distributed water wheel blades 10 are further arranged on the side surface of the water floating operation platform 8 for matching with the hydraulic generator device. Meanwhile, in order to balance the water flow in the annular water tank and simultaneously eliminate the swirling vortex resistance generated at the rear part of the water turbine blades 10 by the rotation of the water floating operation platform 8, a series of water flow pipelines 9 penetrating through the inner ring and the outer ring of the water floating operation platform 8 can be arranged behind each water turbine blade 10.

As shown in fig. 6, 8 and 10, in order to enhance the structural strength of the floating body of the water floating operation platform, improve the reliability of the rotation motion of the water floating operation system, and prevent the catastrophic effect caused by the accidental damage and water inflow of the hollow cavity floating body, the hollow cavity of the water floating operation platform 8 may be filled with filler 22, as in the above-mentioned water surface floating type annular water tank.

The plurality of ram-jet airfoil sails 16 arranged on the water float running platform 8 are carriers for wind energy capture of the wind generator with the water float sails. As shown in fig. 1, 2 and 3, each ramjet wing sail 16 includes a sail head 3, a sail tail 4, a head air inlet set 1 at the sail head 3, and an airfoil air passage array set 2 at two airfoil surfaces of the sail. Wherein, the head air inlet channel group 1 is composed of a series of air inlet channel openings 7 distributed on the head part 3 of the sail; the airfoil air passage array group 2 is composed of airfoil multi-polar air passage ports 5 and 6 distributed on two airfoils of the sail respectively. The series of head inlet ports 7 and airfoil multi-stage ports 5 and 6 form jet flow air passages as shown in fig. 3 inside the ramjet airfoil sail 16.

The sail of the traditional wing section structure has good wind catching capacity, but cannot overcome the windward resistance. The ram jet type wing sail not only keeps the characteristic that the wing sail can catch wind in a large area, but also effectively reduces the windward resistance of the wing sail through the design of the head air inlet channel group and the wing surface air passage array group of the sail, guides the resultant resistance force into the resultant force advancing to the head 3 of the sail, and greatly enhances the wind catching capacity of the wing sail. As shown in fig. 3, when the airflow rushes the jet airfoil sail from the a side of the sail, a high pressure area is created at the a side of the sail, while a low pressure area is created at the B side of the corresponding sail, creating a large pressure differential across the A, B side of the sail. One part of the airflow of the high-pressure area of the A surface of the sail is guided by the airfoil surface of the A surface of the sail to be divided, and the other part of the airflow directly enters the series airfoil multi-stage air passage opening 5; at this time, the series of airfoil multipole air port openings 6 of the sail B surface in the low-pressure area can attract the airflow from the high-pressure area of the series of airfoil multipole air port openings 5 of the sail a surface, and simultaneously siphon the airflow of the series of air inlet port openings 7 of the sail head 3, and the airflow is ejected through the series of airfoil multipole air port openings 6 of the sail B surface in the low-pressure area, so that the resultant force of the movement of the ram-jet wing sail towards the sail head 3 is enhanced, and the water float running system is driven to make horizontal circular movement towards the sail head 3. Conversely, the principle of natural wind striking the jet airfoil sail 16 from the sail B-face is also true. Meanwhile, the series of ram air-jet wing-shaped sails 16 uniformly distributed on the water float running platform 8 have good resultant force guiding of forward motion for different attack angles of wind in horizontal circular motion in different directions.

Of course, in terms of the selection of the sail structure of the wind generator with water float sails, the ramjet wing-shaped sail can be selected, the traditional soft or hard wing-shaped sail without a ramjet jet air port can be selected, and the traditional folding sail with the windward angle controlled by a computer can be selected.

In the design of the horizontal rotation direction of the wind generator with the water float sails, the principle of Coriolis force effect generated by the rotation of the earth can be followed, when the wind generator is used in a northern hemisphere, the head part 3 of the sail is arranged in the front along the counterclockwise direction, and the tail part 4 of the sail is arranged in the rear, so that the wind generator can rotate along the counterclockwise rotation direction 13 in the figures 5 and 11 under the action of natural wind force; when the device is applied to the southern hemisphere, the device is reversely arranged in the same way. Therefore, the horizontal rotation motion of the wind driven generator can be made to conform to the influence of the Coriolis force effect of the earth rotation, the zero-level wind rotation operation is realized, the horizontal rotation motion efficiency is further improved, and the ultra-low wind speed starting and the high-efficiency rotation operation of the wind driven generator with the water float sails are more effectively realized.

Positioning system of wind driven generator with water float sails

The positioning system of the wind generator with the water float sails effectively positions the rotating operation of the water float operation system floating in the annular water tank so as to improve the stable and reliable operation of the wind generator with the water float sails and reduce the operation resistance of the water float operation system. Meanwhile, the positioning system also greatly reduces the construction cost of the wind driven generator.

The positioning system of the wind generator with water float sails generally has two modes: the magnetic positioning is matched with the positioning mode of limiting of the limiting wheel and the positioning mode of shaft positioning. Of course, in practical application, other positioning modes can be adopted, for example, a positioning mode of a limiting wheel, a positioning mode of a mechanical positioning track and the like can be used independently.

[ I ] positioning mode of magnetic positioning matched with limiting wheel for limiting

The magnetic positioning and the spacing of the spacing wheels are matched in a positioning mode, and the magnetic positioning and spacing wheels are combined by one or more groups of magnetic positioning rails and a series of spacing wheels.

The magnetic positioning mode is composed of one or more groups of stator magnetic positioning tracks arranged at one or more positions of the inner side of an inner ring water retaining wall 17 of the annular water tank, the inner side of an outer ring water retaining wall 18 (the surface of the inner ring water retaining wall 17 and the outer ring water retaining wall 18 which enclose the water tank is taken as the reference herein), the lower side of an inner ring water retaining wall seal cover 20 and the lower side of an outer ring water retaining wall seal cover 21, and one or more groups of rotor magnetic positioning tracks which are arranged on the water floating operation platform 8 and correspond to the stator magnetic positioning tracks.

The magnetic positioning mode is divided into a permanent magnetic positioning mode and an electromagnetic magnetic positioning mode.

The basic principle of the positioning mode of the permanent magnetic positioning of the water float running system is further explained by combining the attached drawings:

the permanent magnetic force positioning method generally comprises the following steps: the positioning method comprises a permanent magnet repulsion positioning mode, a permanent magnet attraction positioning mode and a permanent magnet repulsion and permanent magnet attraction combined positioning mode.

1. The positioning mode of permanent magnet repulsion positioning is as follows:

as shown in fig. 6 and 7, the permanent magnetic repulsion force is positioned by: the positioning rail 31 of the permanent magnetic repulsion of the stator is arranged on the water retaining wall 17 of the inner ring of the annular water tank, and the positioning rail 32 of the permanent magnetic repulsion of the rotor is arranged on one side of the water floating operation platform 8, which is close to the water retaining wall 17 of the inner ring and corresponds to the positioning rail 31 of the permanent magnetic repulsion of the stator.

The stator permanent magnetic repulsion positioning rails 31 can also be arranged on the outer ring water retaining wall 18 simultaneously or respectively, and the rotor permanent magnetic repulsion positioning rails 32 are arranged on the water floating operation platform 8 and at the positions corresponding to the stator permanent magnetic repulsion positioning rails 31.

The stator permanent magnetic repulsion positioning rail 31 is installed on the water retaining wall of the annular water tank, and is a better installation mode for the permanent magnetic repulsion positioning rail.

The stator permanent magnetic repulsion positioning rail 31 and the rotor permanent magnetic repulsion positioning rail 32 can be one or more groups; the permanent magnetic materials respectively installed in the stator permanent magnetic repulsion positioning track 31 and the rotor permanent magnetic repulsion positioning track 32 are permanent magnetic materials with the same corresponding magnetic poles.

2. The positioning mode of permanent magnetic attraction positioning is as follows:

as shown in fig. 10, the permanent magnetic attraction positioning mode is as follows: and permanent magnetic attraction positioning rails 33 which are respectively and correspondingly arranged above the water floating operation platform 8 and on the lower side of the annular water tank inner annular seal top cover 20.

The permanent magnetic attraction rails 33 can also be respectively arranged on the lower side of the annular water tank outer ring seal top cover 21 and the upper side of the water floating operation platform 8 corresponding to the annular water tank outer ring seal top cover.

The above-mentioned mounting method for fixing one of the permanent magnetic suction rails 33 on the lower side of the circular water tank capping cover is a preferred mounting method for the permanent magnetic suction positioning rail.

The permanent magnetic attraction tracks 33 correspondingly mounted can be one or more groups; the permanent magnetic materials respectively installed in the corresponding permanent magnetic attraction rails 33 are permanent magnetic materials with opposite corresponding poles.

3. The combined positioning mode of the permanent magnetic attraction and repulsion combined magnetic positioning comprises the following steps:

according to the positioning principle of the permanent magnetic repulsion positioning system and the permanent magnetic attraction positioning system, the permanent magnetic repulsion positioning system and the permanent magnetic attraction positioning system can be simultaneously installed on the wind driven generator with the water float sails to form a positioning mode of strengthening combined permanent magnetic force positioning so as to effectively position the water float running system.

Because the permanent magnetic force positioning is a flexible positioning mode, the positioning precision is not high, and the mode is generally used for positioning the wind driven generator at normal wind speed (namely the wind speed when the water floating running system can be positioned in the middle of the annular water tank to rotate relative to the normal position by the permanent magnetic force generated by the permanent magnetic force positioning in the permanent magnetic force positioning mode).

Under the condition of abnormal wind speed (namely the wind speed when the water floating running system cannot be positioned in the middle of the annular water tank to rotate relative to the normal position by the permanent magnetic force generated by the permanent magnetic force positioning in the permanent magnetic force positioning mode), in order to ensure the normal running of the water floating running system of the wind generator with the water floating sails, the water floating running system cannot be horizontally drifted or horizontally inclined when running, and a limit wheel needs to be arranged to perform rigid mechanical positioning on the water floating running system.

The positioning system for limiting the limiting wheel is characterized in that a series of upper limiting wheels 26 and lower limiting wheels 27 are arranged at one or more positions of an inner ring water retaining wall 17, an outer ring water retaining wall 18 and a water floating running platform 8 of the annular water tank, and/or a series of top limiting wheels 28 are arranged at one or more positions of the lower side of an inner ring water retaining wall seal cover 20, the lower side of an outer ring water retaining wall seal cover 21 and the upper side of the water floating running platform 8. Each series of limiting systems can be composed of 3 or more than 3 limiting wheels, and the specific installation position, the number and the mode of each series of limiting wheels can be reasonably set according to actual needs.

The lower limit wheels 27 and even a plurality of rows of series lower limit wheels are arranged at the opposite positions below the upper limit wheels 26, so that the horizontal drifting limit range of the water floating running system is enlarged, and the water floating sail wind driven generator can run more safely, reliably and stably under various severe weather environments. Meanwhile, a series of lower limit wheels 27 are installed below the upper limit wheels 26, which is also a requirement for realizing safe braking of the wind generator with water float sails. Because the water level in the annular water tank is reduced by gradually draining water during braking, the vertical position of the water floating operation platform 8 in the annular water tank is reduced; meanwhile, in the gradual drainage process, when the water float running system is still in rotary running, the upper limiting wheel 26 gradually loses the limiting function to the water float running system, and a series of lower limiting wheels 27 are required to be installed at the relative positions below the upper limiting wheel 26 for effective limiting so as to ensure that the water float sail wind driven generator is safely braked.

For small-sized wind generators with water float sails and the like with relatively high gravity centers and poor horizontal stability and water surface float type wind generators with water float sails and the like with good capability of resisting waves and jolts, a series of top limiting wheels 28 are particularly required to be arranged on the lower side of the annular water tank inner ring seal top cover 20 and/or the lower side of the annular water tank outer ring seal top cover 21 so as to carry out rigid limiting on the horizontal inclination of the water float running system within a certain range.

As shown in fig. 6, 7 and 10, when normal natural wind acts on the ram-jet airfoil sail 16, the ram-jet airfoil sail 16 catches wind to drive the water-floating operation system floating in the annular water tank to rotate in the horizontal direction, and due to the action of the natural wind, the water-floating operation system will drift horizontally along the natural wind while rotating horizontally, but under the action of the flexible clamping of the magnetic positioning system, the water-floating operation system is positioned in the middle of the annular water tank and rotates stably relative to the normal position. At this time, the upper limit wheel 26, the lower limit wheel 27, and the top limit wheel 28 are all in a suspended idle state.

When the natural wind power is larger than the bearing capacity of the permanent magnetic force generated by the magnetic positioning track system, the water floating running system which runs in the annular water tank in a rotating mode breaks away from the acting force of the permanent magnetic force and continues to drift horizontally along the natural wind, even the water floating running system is inclined horizontally, and under the flexible restraint of the permanent magnetic force of the magnetic positioning track, the water floating running system is safely landed on the upper limiting wheel 26, the lower limiting wheel 27 and the top limiting wheel 28 which is positioned on the lower side of the top sealing cover of the annular water tank in a soft mode, the upper limiting wheel 26, the lower limiting wheel 27 and the top limiting wheel 28 are driven to rotate, so that the water floating running system is stably limited in the normal position in the annular water tank to rotate stably, and therefore the horizontal drifting and the horizontal inclination of the water floating running system are limited in a certain.

When the natural wind returns to the normal natural wind speed, the water float running system in running and rotating can float back to the middle of the annular water tank to run stably and rotatably under the flexible clamping of the permanent magnetic force generated by the magnetic positioning track system. At this time, the upper limit wheel 26, the lower limit wheel 27 and the top limit wheel 28 return to the suspended idle state.

When the three permanent magnetic force positioning devices are used for positioning the water float running system and the water float sail wind driven generator is matched with the limit wheel system to position the water float running system, the water float running system of the water float sail wind driven generator is further ensured to run stably in order to effectively deal with severe weather environments, and the water float running system is further required to be positioned in an enhanced manner by utilizing an electromagnetic suction force compensation positioning mode in electromagnetic magnetic force positioning.

The positioning mode of electromagnetic suction compensation positioning is generally a positioning mode of performing real-time sectionalized strong electromagnetic suction compensation positioning on horizontal inclination of the water float running system in all directions under the control of an electronic controller by directly providing redundant electric power generated by a wind generator with a water float sail at abnormal wind speed for an electromagnetic induction coil to generate strong electromagnetic force.

As shown in fig. 6 and 10, the electromagnetic attraction compensation positioning system is composed of: the electromagnetic suction compensation positioning coil track 36 arranged on the lower side of the annular water tank outer ring seal top cover 21 or the annular water tank inner ring seal top cover 20, the special compensation positioning steel track 35 which is arranged on the water float operation platform 8 and corresponds to the arranged electromagnetic suction compensation positioning coil track 36, and an electronic controller are matched to form an electromagnetic suction compensation positioning system.

The electromagnetic suction compensation positioning coil tracks 36 can also be arranged at the lower side of the water blocking wall top sealing cover 21 of the outer ring of the annular water tank simultaneously or respectively, and the special compensation positioning steel track 35 is arranged on the water floating operation platform 8 and at the position corresponding to the electromagnetic suction compensation positioning coil tracks 36.

The above-mentioned installation method of installing the electromagnetic attraction compensation positioning coil track 36 on the lower side of the annular water tank capping cover is a preferable installation method for the electromagnetic attraction compensation positioning method for reinforcing and positioning the horizontal inclination of the water float running system.

Under normal natural wind speed, when the water float running system runs and rotates stably, the electronic controller does not recognize the signal of horizontal inclination of the water float running system, and the electromagnetic suction compensation positioning is automatically in an idle state. At the moment, the positioning work under the normal wind speed is maintained only by the permanent magnetic positioning system. Fig. 6 is a view for maintaining the positioning at the normal wind speed by means of a permanent magnetic repulsive force positioning system, and fig. 10 is a view for maintaining the positioning at the normal wind speed by means of a permanent magnetic attractive force positioning system.

When the acting force of wind power is larger than the bearing force of the magnetic positioning force generated by the permanent magnetic positioning system, the water floating operation system is in an accelerated rotation state, the water floating operation system can not only horizontally shift along natural wind, but also horizontally incline in a certain section even if the top limiting wheel 28 is leaned on, the electronic sensor can send out a signal that the certain section of the water floating operation system horizontally inclines, and then the section electromagnetic attraction compensation positioning coil track 36 is controlled to generate strong electromagnetic attraction for attracting the special compensation positioning steel track 35, so that the water floating operation system is restored to a normal horizontal position, and the balance compensation positioning work of the horizontal incline of the water floating operation system is completed.

The electromagnetic suction compensation positioning of the real-time subsection of the water float running system is generally designed for small and medium-sized water float sail wind generators with poor running stability, in particular to water surface floating type water float sail wind generators. For large and medium-sized wind generators with water float sails, the gravity center is relatively low, and the stability of horizontal operation is very high, so that an electromagnetic suction compensation positioning device is not required to be arranged generally.

A magnetic positioning mode matched with a limiting wheel for limiting is implemented on the wind driven generator with the water float sails, and a plurality of schemes can be selected. When the wind power generator with the water float sails is used specifically, effective positioning is carried out on the wind power generator with the water float sails in any mode so as to ensure stable and reliable operation of the wind power generator, and the wind power generator with the water float sails needs to be designed comprehensively and flexibly according to multiple parameters such as the diameter of the water float operation platform, the size and the number of the area of the sails, the ratio of the height of the sails to the diameter of a water float operation system, the size of the output power of the wind power generator with the water float sails, construction materials and.

(II) shaft positioning mode

As shown in fig. 8 and 9, in the shaft positioning system, one end of each of a plurality of positioning shaft connecting rods 45 is sleeved on a positioning shaft 46 located at the center of the circular water tank through a positioning shaft bearing 48, and the other end is uniformly fixed on the water float running platform 8 to form the shaft positioning system. A positioning shaft protecting cover 47 is provided on the positioning shaft 46. The shaft positioning system radially positions the water float running system at the middle normal position of the annular water tank by taking the positioning shaft 46 as the center, is a mechanical rigid positioning mode with high positioning precision for the water float sail wind driven generator, and can effectively reduce the manufacturing cost of the water float sail wind driven generator by adopting the shaft positioning mode.

The water float running system will move up and down with the shaft positioning system within the normal range of the up and down movement stroke 49 of the shaft sleeve system if the water level in the annular water tank changes.

The shaft positioning mode is generally most suitable for being applied to small and medium-sized wind generator with water float sails, because although the positioning shaft 46, the positioning shaft connecting rod 45 and the positioning shaft bearing 48 in the shaft positioning system do not bear the weight of the water float running system, the radius span of the positioning shaft connecting rod 45 is increased along with the increase of the diameter of the water float running platform, technical obstacles which are difficult to overcome are brought to the bearing capacity and the stability structural design of the positioning shaft 46, the positioning shaft bearing 48 and the positioning shaft connecting rod 45, higher requirements are provided for the selection of materials, and the construction cost is increased on the contrary.

When the shaft positioning mode is implemented, the inner ring water retaining wall 17 of the annular water tank can be eliminated, and the annular water tank is changed into a water tank structure. The positioning shaft connecting rod can be made of rigid materials or cables and the like.

Stranded flexible braking system of wind driven generator with water float sails

As shown in fig. 6, 8 and 10, the stranded flexible braking system of the wind generator with water float sails comprises: a water inlet and outlet valve 42, a water inlet and outlet bidirectional water pump 43 and a large-area special sand material 39 for grounding brake laid on the bottom 19 of the annular water tank, which are arranged on a series of water inlet and outlet pipelines 41.

When the wind power generator with the water and wind sails needs to be braked, the water inlet and outlet valve 42 and the water inlet and outlet bidirectional water pump 43 on the water inlet and outlet pipeline 41 are opened to gradually discharge liquid in the annular water tank, so that the water floating operation system loses buoyancy and stably runs on the large-area special sand and stone material 39 for grounding brake at the bottom 19 of the annular water tank to stop running. The drainage speed is properly adjusted and controlled, and the grounding braking speed of the water floating running system can be freely controlled, so that the braking of the water floating running system with huge mass is safer and more reliable. In the braking process, because the water floating running system slowly contacts with the large-area soft sand stone material 39 special for grounding braking, great flexible friction resistance can be generated during grounding braking, thereby completing effective and stable grounding flexible braking of the water floating running system and better avoiding the damage to the bottom structure of the water floating running platform 8 by using a hard braking mode.

On the contrary, when the water inlet and outlet valve 42 and the water inlet and outlet bidirectional water pump 43 on the water inlet and outlet pipeline 41 are opened and the liquid is filled into the annular water tank to the normal working water level, the water floating running system floats again from the grounding state and starts and rotates under the action of wind power.

Fifth, supporting generator system of water float sail aerogenerator

The generator system of the wind generator with water and wind sails can be generally as follows: a matched hydro-generator system and a matched electromechanical integrated permanent magnet direct drive power generation system.

(I) matched hydraulic generator system

In the wind driven generator with the water float sails, the matched hydraulic generator power generation system converts the water energy generated by the wind catching operation of the water float operation system into electric energy to be output, and the wind driven generator with the water float sails converts the wind energy into the water energy and converts the water energy into the electric energy to be output.

As shown in fig. 4, 5 and 11, the associated hydro-generator 23 includes: the generator 11, the turbine guide pipe 12 and the turbine blades 29 which are coaxial with the generator 11.

The number of the hydraulic generators 23 in the hydraulic generator set matched with the wind driven generator with water float sails and the magnitude of the single machine power are determined by the diameter of the water float running platform 8, the area of the ram jet airfoil sails 16 and the magnitude of the output power of the wind driven generator with water float sails.

(II) matching electromechanical integrated generator system

In the wind power generator with water float sails, a matched electromechanical integrated power generation system directly converts wind energy into electric energy to be output.

As shown in fig. 8 and 9, the matched electromechanical integrated permanent-magnet direct-drive power generation system comprises: the generator special permanent magnet track 34 is arranged on the inner ring edge of the water floating operation platform 8, and the generator stator coil winding 44 is arranged on the inner ring water baffle wall 17 of the annular water tank and corresponds to the special permanent magnet track 34.

The generator special permanent magnet track 34 arranged on the inner ring edge of the water floating operation platform 8 and the generator stator coil winding 44 correspondingly fixed on the inner ring water retaining wall 17 can also be simultaneously or respectively correspondingly arranged on the outer ring edge of the water floating operation platform 8 and the outer ring water retaining wall 18 of the annular water tank.

The following four exemplary embodiments of the present invention are shown in the drawings to illustrate the specific applications of the preferred embodiment of the wind generator with water sails:

application of water float sail wind driven generator matched with hydro-generator system

As shown in fig. 4, 5, 6, and 7, the embodiment of the wind turbine generator with water float sails applied to the hydro generator system matched with the northern hemisphere adopts a reinforced positioning mode of combined magnetic positioning and limiting by a limiting wheel. The design running direction is counterclockwise rotation.

The combined magnetic force positioning mode is formed by combining a permanent magnetic repulsion positioning rail and an electromagnetic attraction compensation positioning rail. The permanent magnetic repulsion positioning rail is composed of a stator permanent magnetic repulsion positioning rail 31 arranged on the inner ring water retaining wall 17 and a rotor permanent magnetic repulsion positioning rail 32 correspondingly arranged on the water float running platform 8, so that the water wind sail wind driven generator can be positioned at normal wind speed.

The electromagnetic suction compensation positioning track consists of an electromagnetic suction compensation positioning coil track 36 arranged on the lower side of the annular water tank outer ring water retaining wall seal top cover 21 and a special compensation positioning steel track 35 correspondingly arranged on the water floating operation platform 8; the limiting wheel limiting mode matched with the magnetic positioning system is formed by an upper limiting wheel 26 and a lower limiting wheel 27 which are arranged on the inner ring water retaining wall 17 and a top limiting wheel 28 which is arranged on the lower side of the annular water tank outer ring water retaining wall seal top cover 21, and the combined type strengthening positioning of horizontal displacement and horizontal inclination during the rotary operation of the water floating operation system is realized by the electromagnetic suction force compensation positioning mode and the limiting wheel positioning mode.

The running power generation process of the wind driven generator with the water float sails matched with the hydraulic generator system is as follows:

and opening a water inlet and outlet valve 42 and a water inlet and outlet bidirectional water pump 43 which are arranged on the water inlet and outlet pipeline 41, filling water which reaches a normal working water level line enough to float the water floating operation system into the annular water tank, and gradually floating the water floating operation system in the annular water tank on the water surface of the annular water tank.

Under normal wind speed, the ramjet wing sails 16 evenly distributed on the water float running platform 8 catch wind to drive the water float running system to rotate along the anticlockwise horizontal direction 13. Under the action of a permanent magnetic repulsion positioning system, the water floating operation system stably rotates and operates on a relative normal position in the middle of the annular water tank, meanwhile, under the action of the water turbine blades 10 on the outer circular edge of the water floating operation platform 8, water in the annular water tank and the water floating operation system synchronously rotate along the anticlockwise direction 13, the water in the rotation motion rushes to the water turbine flow guide pipe 12 communicated with the annular water tank along the 14 direction and rushes the water turbine blades 29 to rotate, and therefore the generator 11 is synchronously driven to generate electricity; the water flow towards the water turbine guide pipe 12 flows out of the water turbine guide pipe 12 along the direction 15 and joins with the water in the annular water tank to circulate, so that the wind power generator with the water float sails converts the wind energy into the water energy, and simultaneously converts the water energy into the power generation process of the electric energy.

When the wind power is enhanced to reach abnormal wind speed, the permanent magnetic repulsion force generated by the permanent magnetic repulsion force positioning system can not prevent the water floating running system from running relative to the normal position in the middle of the water surface in the annular water tank, when the water floating running system has horizontal drift, the water floating running system is in soft landing on the upper limiting wheel 26 and the lower limiting wheel 27 under the flexible clamping of the permanent magnetic repulsion force positioning system and drives the upper limiting wheel 26 and the lower limiting wheel 27 to synchronously rotate, and the water floating running system is in normal rotation running by being rigidly limited in the middle of the annular water tank. When the water floating running system horizontally tilts while drifting horizontally, the water floating running system leans against the top limiting wheel 28 positioned on the lower side of the outer ring water retaining wall seal top cover 21 under the clamping of the permanent magnetic repulsion force; meanwhile, when the electronic controller also recognizes the horizontal inclination of the section, the electronic controller controls the section electromagnetic attraction compensation positioning coil track 36 to generate strong electromagnetic attraction for attracting the special compensation positioning steel track 35, so that the water floating running system is restored to a normal horizontal position to run stably in a rotating mode, and the water sail wind driven generator is guaranteed to run normally to generate electricity.

When the wind driven generator with water float sails needs braking, the water inlet and outlet valve 42 and the water inlet and outlet bidirectional water pump 43 on the water inlet and outlet pipeline 41 are opened, water in the annular water tank is gradually discharged, the water float running platform in running loses buoyancy and slowly sinks on the special large-area sand stone material 39 paved on the bottom 19 of the annular water tank, and the generator system stops working along with the water float running platform, so that flexible grounding type safety braking of the water float running system of the wind driven generator with water float sails is realized.

The hydroelectric generating set 23 matched with the implementation can adopt a traditional through-flow type hydraulic generator, and the paddle blades of the hydraulic turbine can adopt a fixed paddle type or a rotating paddle type; the arrangement of the hydraulic generator can also be a full through-flow type or a semi-through-flow type. The energy conversion efficiency of the through-flow type hydraulic generator system is generally over 90 percent, and some of the through-flow type hydraulic generator systems even exceed 94 percent, so the hydraulic generator system with the low water head structure is particularly suitable for matching with the conversion of electric energy in the embodiment.

Of course, in the wind turbine generator with water float sails, which is matched with the water turbine generating system, the water float running system can be positioned by matching with an installation shaft positioning system, an independent installation limiting wheel positioning system, a mechanical track positioning system and the like according to actual conditions, so that the water turbine set generating mode of the wind turbine generator with water float sails is implemented.

Application of water float sail wind driven generator matched with electromechanical integrated generator system

The matched electromechanical integrated generator system is an implementation mode of realizing electromechanical integrated direct-drive power generation by the wind driven generator with the water float sails. The implementation mode is applied to the wind driven generator with the water float sails, particularly to the wind driven generator with the small and medium water float sails, has high operation conversion efficiency, and is particularly favorable for further reducing the construction cost of the wind driven generator with the water float sails.

As shown in fig. 8 and 9, the shaft positioning system positions the water floating operation system at the middle normal position of the annular water tank radially with the positioning shaft 46 as the center, under the driving of wind, the ramjet airfoil sail drives the water floating operation system to rotate with the wind, the generator special permanent magnet track 34 fixed on the inner ring edge of the water floating operation platform 8 generates moving magnetic lines of force in the synchronous rotation with the water floating operation system, and the generator stator coil 44 correspondingly fixed on the inner ring water retaining wall 17 cuts the moving magnetic lines of force generated by the generator special permanent magnet track 34 to generate current, thereby completing the electromechanical integrated permanent magnet direct drive power generation.

In the embodiment, a positioning mode of an axis positioning system with higher positioning precision is directly adopted, so that the direct-drive power generation system which is matched with the water float sail wind power generator and is integrated with the machine is particularly favorably and directly installed on the water float sail wind power generator, and the manufacturing cost is greatly reduced.

Of course, the water float sail wind power generator which is matched with the electromechanical integrated permanent magnet direct drive power generation mode can also adopt a magnetic positioning and limiting wheel limiting mode, and can also independently use a limiting wheel positioning mode, a mechanical positioning track positioning mode and the like to implement positioning. However, the electromechanical integrated permanent magnet direct-drive power generation mode has higher requirement on the operation precision of the water floating operation system, and the magnetic positioning is matched with positioning modes such as limiting of the limiting wheel, so that the positioning precision is not as good as that of an axis positioning mode, and the electromechanical integrated permanent magnet direct-drive power generation mode is not favorably matched and used. Therefore, when the electromechanical integrated permanent magnet direct drive power generation mode is adopted, a shaft positioning system is generally adopted to position the wind driven generator with the water float sails.

Third, water float sail wind power generator applied on water

The wind driven generator with water float sails can be built on the tops of land and buildings, and can also be widely applied to the water surfaces of rivers, lakes and oceans.

Water surface floating type wind generator with water float sails

Fig. 10 is a schematic cross-sectional view of a floating-on-water sail wind turbine according to an embodiment of the present invention. The wind driven generator with the water float sails is different from the wind driven generator with the water float sails applied on land, and has the main technical characteristics that: the annular water tank is a water surface floating type annular water tank floating on the water surface 25, the water surface floating type annular water tank adopts an inner cavity structure, and the inner cavity is filled with oil filler 22. In order to make the water surface floating type annular water tank float on the water surface within a normal range, more than three underwater fixing anchors 24 are arranged for restraining.

The underwater fixed anchor 24 in the scheme can also adopt a movable anchor structure.

Because the water surface floating type annular water tank floats on the water surface, the water floating type annular water tank can simultaneously bump up, down, left and right under the influence of wind waves in the rotating motion of the water floating operation system, and the rotating motion in the horizontal direction can be extremely unstable under the influence of the wind waves. However, when the diameter of the water surface floating type annular water tank is far larger than the cycle wavelength of the wind waves, the bumping force of the wind waves to the water surface floating type annular water tank is offset. Therefore, the embodiment is generally suitable for the application of large, medium or ultra-large water floating type wind generator with water floating sails.

The water float running system of the water float type water float sail wind driven generator makes horizontal rotation motion in a certain direction under the action of natural wind and drives water in the water float type annular water tank to rotate synchronously, the rotation motion of the water float running system with huge mass also has strong rotation motion gyro effect, and the strong storm bumping resistance of the water float type water float sail wind driven generator is further improved.

And because the water float sail wind power generation adopting the shaft positioning mode is generally only suitable for the structure of a medium and small-sized wind power generator, in order to improve the resistance of the water float sail wind power generator to strong typhoon, the positioning mode is generally a reinforced positioning and limiting mode of combining magnetic positioning and limiting with a limiting wheel.

Fig. 10 shows that the generator system of the present embodiment is a hydro generator system.

In order to further improve the wind and wave resistance stability of the water floating type water floating sail wind driven generator, a combined type limiting mode of multiple magnetic force positioning matched with limiting wheels for limiting is adopted in the design of magnetic force positioning matched with limiting wheels for limiting.

The magnetic positioning system of the scheme is a permanent magnetic suction positioning system which is arranged on the lower side of the outer ring seal cover 21 of the water surface floating type annular water tank and is correspondingly arranged on a permanent magnetic suction positioning track 33 on the water floating operation platform 8, so that the permanent magnetic suction positioning of the water floating operation system is realized at normal wind speed. The first group of electromagnetic attraction compensation positioning system consisting of the special compensation positioning steel track 35 arranged on the water floating operation platform 8 and the corresponding electromagnetic attraction compensation positioning coil track 36 arranged on the lower side of the inner ring water retaining wall seal top cover 20 is a strong electromagnetic attraction compensation positioning system which directly provides the electromagnetic attraction compensation positioning coil track 36 with the redundant electric power converted by the water surface floating type water floating sail wind driven generator under the abnormal strong wind condition to generate strong electromagnetic attraction, and carries out real-time subsection strong electromagnetic attraction compensation positioning on the horizontal inclination of the water floating operation system in each direction under the automatic control of an electronic controller. And a limiting wheel system consisting of an upper limiting wheel 26 and a lower limiting wheel 27 which are arranged on the inner ring water retaining wall 17 of the water surface floating type annular water tank and a top limiting wheel 28 which is arranged on the lower side of the outer ring sealing top cover 21 of the water surface floating type annular water tank is matched to carry out the reinforced combined positioning of the horizontal drifting and the horizontal inclination of the water surface floating type water floating sail wind driven generator in the strong wind and big wave environment.

In order to better cope with the severe climate of abnormal heavy storm, a top limiting wheel 28 is not arranged on the lower side of the outer ring seal cover 21 of the water surface floating type annular water tank, and an electromagnetic suction compensation positioning coil track 36 and a special compensation positioning steel track 35 are correspondingly arranged on the position and the corresponding water floating operation platform 8 to form a second group of strong electromagnetic suction track system which is matched with the first group of strong electromagnetic suction track system, and the redundant electric power converted by the water floating sail wind power generator in abnormal strong wind is directly supplied to the electromagnetic suction compensation positioning coil track 36 to generate strong electromagnetic suction, so that the horizontal inclination time-sharing and inter-time-sharing positioning capacities in all directions of the water floating operation system are strengthened under the automatic control of an electronic controller.

The basic principles of the permanent magnetic repulsion force positioning system, the electromagnetic attraction force compensation positioning system and the limiting wheel limiting system arranged in the scheme and the power generation principle of the water turbine system matched with the basic principles are detailed in relevant contents in the specification, and are not described in detail herein.

(II) waterborne fixed pile type wind generator with water float sails

In shallow water areas of rivers and lakes and offshore areas, a series of annular water tanks supported by a plurality of pile foundations can be directly constructed at the water bottom to form the water-borne fixed type wind-sail wind driven generator.

The water fixed pile type water float sail wind driven generator can adopt a matched water turbine power generation system or a permanent magnet direct drive electromechanical integrated power generation system on a matched generator system; in the limiting mode, a magnetic positioning mode matched with the limiting wheel for limiting can be adopted, a shaft positioning system can also be adopted, and independent limiting wheel limiting and mechanical positioning rails and other positioning modes can also be adopted. The structural design and the power generation operation principle of the wind generator are the same as those of the corresponding wind generator with the water float sails, and the details are not repeated.

Application of super-power water-floating wind turbine sail wind-driven generator

Due to the physical structure advantages of light weight and heavy weight of the water float sail wind driven generator and low gravity center of the main structure, the bottleneck limit that the single machine capacity of the existing mainstream wind driven generator cannot be large is thoroughly eliminated in technical design and process manufacturing, the single machine million kilowatt level power generation can be completely and easily realized, and the unit construction cost of the water float sail wind driven generator is lower than that of a small and medium water float sail wind driven generator.

Although the technology involved in the implementation of the present ultra-high power wind generator with water float sails is complex and immature, there is no technical bottleneck, and the basic structure, the power generation principle, the positioning principle, etc. are the same as those of the above wind generator with water float sails, and only the relevant main data involved in the ultra-high power wind generator with water float magnetic force positioning sails will be briefly described:

[ I ] Main structural data of the present embodiment

As shown in fig. 11, 12 and 13, the 180-ten-thousand-watt ultra-high power wind generator with water float sails adopts a positioning mode of combination strengthening type magnetic positioning and matching with limiting wheels for limiting for an ultra-large diameter water float running system, 36 stamping jet wing type sails are arranged on a water float running platform 8, the matched 180-thousand-watt ultra-high power water turbine generator set consists of 10 single-machine 18-thousand-kilowatt water turbine generators 23, and a wind power plant central control tower 50 is designed in the center of the water float sail wind generator.

The design data of the ultra-large water floating operation platform 8 is approximately as follows: a diameter 1280m, a circumference 4021m,

the width is 40m, and the height is 20 m; the design data for a ram-jet wing sail 16 is roughly: the height is 136m, the width is 55m, the thickness is 19m, and the wind sail spacing is 56.70 m.

[ II ] buoyancy description of ultra-large water-floating magnetic positioning operation system

As shown in fig. 11, the 2/3 displacement of the above dimensional data of the water floating platform 8 is 214 ten thousand tons. The total weight of the hollow structure ram air-jet wing sail 16 constructed by reinforced concrete of the above data is about 61 ten thousand tons, and the total weight of the water floating operation platform 8 of the internal cavity structure constructed by reinforced concrete of the above data is about 120 ten thousand tons, so the total weight of the water floating operation system is 181 ten thousand tons, which is much smaller than the working displacement of 214 ten thousand tons 2/3. Therefore, the huge water float running system of the wind driven generator with the water float sails can completely float in the position around the 2/3 working waterline to safely and stably rotate in the annular water tank under the action of wind power.

The above description is only a preferred embodiment of the present invention, but the scope of the present invention is not limited thereto. Any changes or substitutions that may be easily made by those skilled in the art within the technical scope of the present disclosure are intended to be included within the scope of the present disclosure. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
