Description

Horizontal Axis Twin Wind Turbine with Radial Wind Chambers}

The present invention relates to a horizontal shaft wind turbine, and more particularly, to a horizontal shaft wind turbine having improved efficiency by improving the structure and shape.

In general, multi-wing wind turbines using drag method in horizontal shaft wind turbines are less efficient than conventional three-foil propeller type horizontal shaft wind turbines, and research and development have not been actively conducted. However, from the physics principle, the output coefficient of the conventional three-wing propeller-type horizontal axis wind turbine blade, which causes the horizontal wind force to lift and drag resistance to the vertical wing surface and converts it back to the vertical rotational force, is generally 0.47 to 0.49. It can be seen that the energy loss due to frictional resistance, such as can not be overlooked.

Specifically, the three-wing propeller-type horizontal shaft wind turbine currently widely used has to have a blade length of several tens of meters in order to obtain the required electrical energy due to the large energy loss rate due to the wind as described above. . In addition, the vertical wind pressure applied to each of the blades of several tens of meters in length generated a torsional pressure on the hub portion of the pivot axis with tremendous moment force. Excessive wing fixing device is required, and the material of the wing also needs to be made of special material. Therefore, the horizontal axis wind turbines currently in use are excessively expensive to manufacture the vanes, and the height and size of the steel cylindrical tower supporting the wind turbines are enormously increased to withstand the horizontal wind pressure applied to each vane. Inevitably, there is a problem in that an excessive installation cost and a considerable maintenance cost are required.

Therefore, it is assumed that a horizontal wind turbine, which is a device that uses horizontal wind force as a drag force on a wing perpendicular to the wing and uses it as a rotational force, can minimize energy loss and obtain higher efficiency. can do. However, the existing horizontal axis wind turbine currently being manufactured and used is significantly less efficient bar, the problems are as follows.

Firstly, the existing three-wing propeller type wind turbines have very low power at low wind speeds of 4-6 m / s and generally exhibit less than 10% of their rated power. This is because the blade shape is a form of airfoil to obtain rotational force by using the lift force of air, so the power generation efficiency is very low at low wind speeds. However, in general, the average annual wind speed of each region on the earth where wind power generators can be installed is 4-8 m / s. Therefore, in order to increase the efficiency at the annual average wind speed zone, the existing three-wing propeller type wind turbine is more efficient. It is hard to expect.

Second, the choice of airfoils is the first step in designing high-efficiency blades to increase power in existing three-wing propeller type horizontal axis wind turbines. The first step is to select an airfoil with a high lift ratio (lift / drag). In addition, the characteristic of the airfoil to be considered in the wind blade is that the reduction of the lift ratio due to the surface roughness of the airfoil should be small. Wind generators usually operate for a life of about 20 years. During operation, the surface of the blade becomes rough due to bird collisions, insect attachment, and sand wind. Therefore, even if the surface of the blade is rough, it is possible to minimize the decrease in the output of the wind turbine by using an airfoil with a small reduction in the drag ratio.

Third, in the existing three-wing propeller-type horizontal axis wind turbine, electric and mechanical devices such as yawing, which are wind direction control devices, are needed to produce electric power by constantly rotating the blades according to the wind direction which changes frequently. In order to protect the wind power generator, the pitch of the blade should be used to reduce the frictional force of the wind while reducing the lift force acting on the blade by adjusting the angle of the blade. In this case, in the existing three-wing propeller type horizontal shaft wind turbine for the wind speed above the rated output, the stall speed is minimized by adjusting the blade angle to minimize the lift and drag acting on the blade of the blade. As a result, power cannot be generated at wind speeds above the rated power.

Fourth, the weight of each rotor, generator, controller, etc. on the support tower in the existing three-wing propeller type horizontal shaft wind turbine is 9 Ton, which is the sum of three blades based on a 1MW wind turbine. Natsel is about 15 Tons and is installed on the support tower with huge weight. In order to control these rotors in the direction of the wind direction, it takes a huge load on the yawing, and the bearing devices supporting these rotors are also manufactured by special methods in size and strength, thus increasing the manufacturing cost and maintenance cost. Brings about.

Fifth, the blade of the existing three-wing propeller-type horizontal shaft wind turbine is usually 80-100 m in diameter in order to obtain a high output of MW or more, and a special device is required for manufacturing, and a considerable manufacturing cost is required. In addition, the noise caused by the rotation of the blade of this size, low frequency generation and the impact of migratory birds cause environmental problems. In addition, due to the large, unnatural shape, it does not fit with the surrounding natural environment, so it is resisted by local residents when constructing a new wind farm.

The present invention has been proposed to solve the above problems, the technical object of the present invention is to improve the structural and functional problems of the conventional horizontal axis wind turbine developed on the basis of the hydrodynamic basic principle is more efficient To provide horizontal wind turbines.

The horizontal axis wind turbine according to the present invention is to maximize the area of the blade rotating in the wind direction in order to use the wind as the most efficient energy source, by forming several wind chamber to increase the frictional resistance of the air It is designed to have a configuration that reduces the loss of rotational energy by minimizing the air friction resistance by converting this to rotational energy and closing the wing of the part rotating opposite to the wind.

In addition, the horizontal axis wind turbine according to the present invention has a structure that can double the production efficiency of the power by installing a turbine that is rotated by the wind on each side of the rotary support structure and the wing opening and closing control device on both ends of the rotary support structure It is installed to enable the most efficient control of opening and closing of inner and outer blades and outer blades of both wind turbines. The wind turbines can be operated in the same direction as the wind direction. The wing shape closed at the air plane always directed the wind turbine in the direction of the wind as the vertical direction key in the aircraft.As a result, two wind vanes were installed on the upper part of the rotating support structure so that the wind turbine always rotated in accordance with the wind direction. Devised.

In addition, the horizontal axis wind turbine according to the present invention is designed as a three-dimensional space truss frame (Space Truss Frame) to expand the size of the wings structurally and safely when the diameter of the turbine is expanded to obtain the required power energy, The turbine features a wing open / close rail control hydraulic cylinder arrangement that allows the turbine to close all wings to minimize air resistance.

In order to solve the problems as described above, the horizontal axis wind power device of the present invention is a rotary support structure installed on the support tower vertically installed on the ground, a plurality of windscreens installed on both sides of the rotary support structure formed to rotate by wind In the horizontal axis wind turbine formed, each of the plurality of windscreens are formed in the inner and outer wings and outer wings are formed to expand and fold outward in accordance with the direction of the wind, the inner and outer wings are both ends of the rotary support structure Opening and closing is controlled by the wing opening and closing adjustment device installed in.

The wing opening and closing adjustment device of the horizontal axis wind power device of the present invention comprises a wing opening and closing control rail formed of a wing opening section, inclined lamp section and wing closing section, the respective inner wings are connected to the wing opening and closing roller bar, the As the wing opening and closing roller bar moves along the wing opening and closing control rail, the inner and outer wings and the outer wing are interlocked to open and close. The blade opening and closing roller bar is connected to the end of the inner blade, the inner and outer wings were to be opened and closed at the same time by the interconnect chain.

The inner and outer wings and the outer wing of the horizontal axis wind power device of the present invention is formed so that the lower section is opened around the front direction of the wind, the upper section is closed, two wind vanes on the top of the rotary support structure Installed, the wind vane was designed such that the wind turbine is always directed in the wind direction along with the wind turbines on both sides of the rotary support structure.

The object of the present invention described above will become more apparent from the preferred embodiments of the present invention described below with reference to the accompanying drawings, by those skilled in the art.

In general, horizontal multi-axis drag type wind turbines have limitations in terms of efficiency of rotational energy, weight, size and height of turbines. Much research has been done on this. The present invention empirically solves the limitations of the horizontal multi-axis drag type wind turbine, and the horizontal axis drag type wind turbine is more efficient in converting horizontal wind into rotational energy than the horizontal three-wing propeller type wind turbine. As an example, I tried to present an empirical alternative.

In the present invention, the size of the turbine can be manufactured to a desired size through a radial disk truss support structure as a method of manufacturing a turbine size to a desired size as a limitation of the existing horizontal axis multi-wing drag type wind turbine.

In order to overcome the low efficiency limitations on the rotational energy of the horizontal multi-deck type drag type wind turbine, the present invention uses several wind turbines whose three sides are closed by the opening of the inner and outer blades and the outer blades and the windshield attached to each radial truss. In addition to increasing efficiency by providing a method of converting the maximum air friction resistance to rotational energy by creating a chamber, wind chambers are closed by closing the wings in each direction of the rotating part as opposed to wind in order to reduce the loss of rotational energy. The proposed method is to reduce the loss of rotational energy by reducing the air friction resistance by rotating the wind turbine.

In addition, in order to overcome the limitation that the length of the blade must be increased in order to produce high power in the existing horizontal three-wing propeller type wind turbine in the wind turbine of the present invention on both sides of the rotary support structure installed on the top of the support tower By installing two wind turbines, the power production efficiency has been doubled, and the size, weight, height, and area can be considerably reduced compared to the existing three-wing propeller type wind turbines. In order to solve the limitation of the weight of the turbine, each blade of the turbine is made of glass fiber reinforced plastic-based new material (GFRP), and the radial disc truss structure and the outer ring are made of aluminum metal.

The device of the present invention is a structure that can detachably attach all parts such as wings and rotating support structure of a wind turbine, which requires special technology and special materials required for the manufacture and installation of a large-scale horizontal three-wing propeller type wind turbine. Unlike general technology that can manufacture and install general mechanical devices, all devices can be manufactured and installed, which shows the advantages of reducing production and installation costs, and can be used in many places for general purpose. Its technical advantage is that it can be used as an alternative energy source for energy, thus providing a way to prevent global warming and solve global resource depletion.

The foregoing description relates to specific embodiments and can be easily understood by those of ordinary skill in the art that various modifications and changes can be made without departing from the spirit and scope of the invention as indicated by the claims. Could be.

In addition, the windshield attached to the inner and outer wings, the outer wing and the inner truss support forms several wind chambers with three sides to be converted to rotational energy with the maximum frictional resistance against the wind.
