Description

{Wind and hydro hybrid power plant}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a wind power and hydro power hybrid power generation system using a super gear.

More specifically, it is possible to obtain a constant output power by dividing the irregular, multi-directional wind or hydraulic force by uniformly dividing the irregular and multi-directional wind turbine by using natural wind and hydraulic power, and when the wind or hydraulic power is weak, The present invention relates to a combined power generation apparatus for a wind power and a hydro power using a super gear which can obtain a maximum output with a minimum mechanical power by a large super gear.

Typically, a power generator using a wind power generator, a tidal generator using a tidal power generator, and the like are typical examples. Among them, a wind power generator is called a windmill, which is a device used to generate electric power by using a mechanical force through a rotary shaft.

These wind power generators are divided into a horizontal axis wind turbine and a vertical axis wind turbine. The horizontal axis is a propeller type, and the aerodynamic lift force Using a rotor composed of blades, the power generation efficiency is relatively high, but the direction of the rotor must be changed according to the wind direction, and a device for changing the angle of the blades according to the wind intensity is needed.

In addition, when the horizontal axis is used, the axis of the rotor is positioned at least higher than the radius of the rotor. Therefore, in order to connect the generator shaft with the rotor shaft located at a high position, the generator is installed at the same height as the rotor shaft, It is installed at almost the same position, or a device for converting the horizontal turning force to the vertical turning force is provided and connected to the generator. In this case, there is a risk that mechanical damage may occur due to strong wind and maintenance and repair are not easy in the case of the former. In the latter case, energy loss occurs in the process of converting the horizontal rotation force into the vertical rotation force.

On the other hand, in the case of the vertical type, there are Darrius Rotor which uses wind lift and Savonius Rotor which uses drag force of wind, but in the case of Darius type, the output of the generator is weak, And a supplementary one-rotation power unit is required. In the case of the Sovonius equation, since the rotation speed can not be higher than the wind speed due to the use of the drag force of the wind, the rotation speed of the rotation shaft is limited, It is mainly used as a wind power generator.

Therefore, much research has been done recently to overcome low efficiency, which is a weak point of vertical type. For example, improving the design, structure or assembly of the blades, improving the manner in which the blades are attached to the support structure, improving the pitch angle control system of the blades so that the angular velocity of the blades is constant do.

U.S. Patent No. 4,718,821 discloses an apparatus for periodically oscillating each blade during rotation by varying the pneumatic pressure acting on the individual blades, which has the problem that the blade is mechanically prone to damage, Leading to increased costs

Unlike the above-described individual pitch angle control systems, a system for collectively adjusting pitch angles of the entire blades is disclosed in U.S. Patent No. 4,299,537, in which a blade is rotated by an eccentric ring to an eccentric ring.

However, in this case, since the pitch angle of the blade is determined by the wind, there is a problem in that it is impossible to positively control the blade pitch angle for obtaining a high efficiency wind force and is insufficient to cope with a sudden change in the wind direction.

In addition, conventionally, when a single generator is connected to one blade, if the wind is not blowing at a place or height where the blade is installed, it is difficult to supply electricity with a constant electric power .

In addition, the wind turbine generator is operated by a wind blowing naturally. However, the turbine generator is not limited in installation position as compared with the tidal power generator. However, when the wind turbine is not blown, the power generator itself is not possible. Therefore, it is urgent to develop a power generation system capable of stably generating and supplying electric power.

Hereinafter, embodiments of the present invention will be described.

1 is a basic configuration diagram of a combined power generation system using a super gear according to the present invention.

1, a wind power and hydro power hybrid power generation apparatus 100 according to the present invention includes a fluid induction guider 110, a rotating unit 120, a rotating shaft 130, a super gear 140, a starting gear 150, And includes a starter motor 160.

The fluid guiding guider 110 includes an annular first outer rim 111 supported by the frame 101 for guiding an external fluid to the inside.

The fluid guiding guider 110 also includes a second outer rim 112 disposed coaxially with the first outer rim 111 within the first outer rim 111.

Also, the fluid induction guider 110 includes a plurality of stator blades 113 fixedly installed between the first and second outer rims 111 and 112, and radially installed at regular intervals.

Here, the stator blades 113 are formed to be deviated from the first and second outer rims 111 and 112 in the radial direction. That is, the stator blades 113 are arranged so as to form an acute angle with the diameter line, so that the fluid introduced from the outside is directed to the upper surface of the rotor blade (described later) of the rotation unit 120, .

Meanwhile, the stator blades 113 may be fixedly installed to maintain a fixed angle, but the present invention is not limited thereto. However, the rigidity of the installation shall be ensured so that the angle of installation of the fluid does not change.

The rotating unit 120 includes a first inner rim 121 rotatably mounted coaxially with the second outer rim 112 within the second outer rim 112.

The rotation unit 120 includes a second inner rim 122 rotatably installed coaxially with the first inner rim 121 in the first inner rim 121.

The rotation unit 120 is fixedly installed so as to connect between the common center axis s of the first and second inner rims 121 and 122 and the first inner rim 121, And a plurality of rotor blades 123 rotated by the fluid input of the fluid flowing through the fluid induction guider 110.

3 and 4, the rotor blade 123 includes a pair of parallel blade frames 123a connecting the first inner rim 121 to the center axis s, A fluid collecting part 123b integrally formed at the outer end of the fluid collecting part 123a and having a surface opposed to the fluid being opened and a fluid collecting part 123b formed in a bottom surface of the fluid collecting part 123b, And a plurality of resistance protrusions 123c that interfere with the smooth flow of the fluid to be collected in the fluid collecting part 123b and delay the rapid discharge of the fluid from the fluid collecting part 123b.

The fluid collecting unit 123b can collect the fluid (water or wind having the falling water), thereby doubling the rotational power. The resistance protrusion 123c also delays the fluid flow in the fluid collecting unit 123b So that a larger rotational power can be obtained. In addition, the resistance protrusion 123c widens the contact area with the fluid to enlarge the hydraulic or wind-receiving area, which also serves to double the rotational power.

5 shows another example of the rotor blade 123. The rotor blade 123b shown in FIG. 5 has the same fluid collecting part 123b as the rotor protrusion 123c except that the fluid collecting part 123b So that the function of the resistance protrusion 123c is further enhanced.

2, the wind power and hydro power hybrid power generation apparatus 100 of the present invention may further include a housing 170 in which the fluid induction guider 110 and the rotation unit 120 are installed .

The housing 170 has a plurality of casters 171a at its bottom and a base plate 171 supported at one side by a hinge pin so as to be able to move around the hinge pin.

The housing 170 is provided on the base plate 171 and has a housing body 172 having a louver 172a into which fluid flows on both sides.

The housing 170 is provided on both sides of the housing main body 172 at both sides of the housing main body 172 and has a direction plate 173 for displacing the direction of the housing main body 172 in accordance with the direction of the fluid. Such a housing 170 can be more effectively exerted when the fluid is wind.

A fluid guide portion 174 for guiding the fluid passing through the upper portion of the housing main body to the inside of the housing main body may be further provided on the upper portion of the housing main body 172.

The fluid guiding portion 174 includes an induction duct 174a which is formed in an upper portion of the housing main body 172 to communicate with the housing main body 172 and has both sides communicated with the outside, And a guide collar 174b hinged to an upper end of the guide duct 174a for guiding fluid introduced from one side or the other side of the induction duct 174a to the inside of the housing main body.

According to this configuration, not only the fluid flowing from the side surface of the housing main body 172 but also the fluid on the upper side of the housing main body 172 is utilized to rotate the rotating unit 120 therein, will be.

In addition, a vertical blocking film 175 or a horizontal blocking film 176 may be installed on both sides of the housing 170 to block strong winds (for example, a typhoon or a tornado) due to a change in the weather.

A plurality of louvers 175a and 176a are formed in the respective barrier membranes 175 and 176. The louvers of the respective barrier membranes may be controlled manually or electromagnetically to control the flow of the fluid.

Referring again to FIG. 1, the rotation shaft 130 is connected at one end to the center axis s. Accordingly, the center axis s is rotated according to the rotation of the rotation shaft 130.

The super gear 140 is connected to the other end of the rotating shaft 130. The starting gear 150 is connected to the super gear 140 with a smaller diameter than the super gear 140, The starter motor 160 rotates the starter gear 150.

The reason why such a configuration is necessary is that when the starting power is rotated by the starter motor 160 when the fluid is weak in power or at the initial stage, when the large diameter super gear 140 connected to the starting gear 150 rotates Accordingly, smooth rotation and initial rotation of the rotation unit 120 connected via the rotation shaft 130 and the center axis s are assisted.

8, the super gear 140 may be constructed by assembling and inserting the gear teeth 142 into the band-shaped base 141. Since the super gears 140 have a large diameter, it is difficult to manufacture them as an integral type. Therefore, the super gears 140 are divided into a circular arc shape and then combined into a circular shape. In this case, since it is difficult to process the gear teeth 142 integrally, it is possible to solve the manufacturing difficulty by constructing the gear teeth as shown in FIG. 8, Which is advantageous in terms of maintenance.

Although only gears have been described above, chain sprockets can also be produced by the same method.

6, the present invention may further include an amplifying member 180 connected to the super gear 140 in a coaxial relationship to amplify the rotational power of the super gear 140.

The amplifying member 180 has a smaller diameter than the super gear 140 and is connected to the super gear 140 in a coaxial relationship with the amplifying drive wheel 181. And an amplifying follower 182. The amplifying member 180 amplifies the output power output from the super gear 140 and doubles the rotational power finally output.

In this connection, FIG. 7 shows a starter motor 183 having a small diameter in the start motor 160, a first large gear 184 engaged with the starter gear 183, 184 are provided with a first small gear 185 in a coaxial manner such that the first small gear 185 is engaged with a second large gear 186 and the second large gear 186 is coaxially A second small gear 187 may be provided and the second small gear 187 may be connected to the generator 188.

According to this configuration, when the power provided by the first startup motor 160 is amplified in the process of passing through a plurality of gears and output through the final second small gear 187, the power amplified by the first power is output Since the generator 188 is activated by the amplified output, the efficiency of energy acquisition can be increased.

6, the present invention includes a power storage battery 191 connected to the amplifying follower 182 to accumulate rotational power output from the amplifying follower 182, And a controller 193 for selectively controlling whether to supply the current of the transformer 192 to an external device or to supply the current to the external device.

9 shows another example of a wind power and hydro power hybrid power generating apparatus according to the present invention. The power generating apparatus includes an upper rim 210 and a lower rim 210 disposed coaxially with the lower rim 210, A plurality of stator blades 230 arranged in a circumferential direction between the upper and lower bushings 210 and 220 and fixedly arranged at predetermined angles at predetermined intervals; And a rotation shaft 240 connected to the rotation shaft 240 and fixedly disposed at a predetermined angle along the circumferential direction of the rotation shaft 240.

A super gear 281 is provided at the lower end of the rotary shaft 240 and a starter gear 282 connected to the super gear 281 is installed. The starter gear 282 is connected to the starter motor 283, The rotor blade 250 is rotated using the super gear 281 when natural energy is weak, as described above.
