The present invention relates to a wind power generator, and more particularly, to a wind power control mechanism of a wind generator to maintain a constant rotation state in conjunction with the wind strength in a vertical wind power generator.

Typically, a wind turbine is classified into a horizontal shaft generator and a vertical shaft generator according to the direction in which the rotating shaft of the blade (blade) is installed. The horizontal shaft generator has a high manufacturing cost due to its structure, and the vertical shaft generator is disadvantageous in terms of power generation efficiency. In order to overcome the low efficiency, which is a weak point of the vertical axis generator, efforts are continuously made to improve the design structure or assembly method.

For example, the "vertical axis windmill structure for wind power generators" of the registered utility model No. 0387339 is a vertical axis windmill 20 consisting of a plurality of vanes 23A and upper and lower covers 24, 25 vertically, and the vertical axis windmill 22 Wind vane 30 disposed on the shaft 21 of the upper side, a first wind collecting guide member 60 for guiding the vane 23A of the windmill 20, and the upper cover 24 of the windmill 20 The second wind collecting guide member 70 collects and guides the wind passing through the upper portion.

According to this configuration, the wind blowing from the front of the windmill is collected and guided to the front side of the windmill to collide with the vane of the windmill to rotate the windmill, and at the same time collect the wind blowing from the upper part of the windmill to the other side of the windmill. It is expected to improve the rotational efficiency of the windmill by rotating the windmill by hitting the front of the vane.

However, although the first guide member and the second guide member are linked to the strength of the wind within a certain range, there is a disadvantage in that the range covering from the weak wind to the strong wind is insufficient to improve the efficiency.

Accordingly, the present invention is to solve the above-mentioned disadvantages, and to provide a wind turbine control mechanism of the wind generator to maintain a constant rotational state in conjunction with the wind strength in the vertical axis wind generator.

In order to achieve the above object, the present invention provides a wind power generator rotatably mounted on a vertical axis and rotatably provided on the sleeve: radially fixed to cooperate with the sleeve 12 and a radius of curvature. A blade 20 formed in the shape of a curved surface to be changed; Wind-proof means rotatably installed on the sleeve to surround the blade, having a windshield on at least one surface; Connecting means installed to allow a relative position change between the rudder and the windbreak means; And control means electrically connected to the connection means to provide an output according to a signal change of the wind speed sensor.

As another feature of the present invention, the blade is formed in a shape in which the radius of curvature decreases toward the upper side.

As another feature of the present invention, the wind-proof means has a windshield to block 20-30% of the circumferential surface on the frame formed of a cylindrical skeleton.

As another feature of the present invention, the connecting means is a wire fixed to each of the left and right sides of the rudder, a winding roll rotatably installed to wind the respective wires, and each of the winding rolls are installed to interlock with each other Gear and a motor connected to the winding roll of the one side.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram showing the main part of the wind generator according to the present invention, Figure 2 is a block diagram showing a blade of the wind generator according to the present invention, Figure 3 is a block diagram showing the operation of the blade according to Figure 2, Figure 4 5 is a block diagram showing the operation of the connection means according to FIG.

The present invention relates to a wind generator in which a sleeve 12 is rotatably mounted on a vertical axis 10 and a rudder 15 is rotatably provided on the sleeve 12. The sleeve 12 is rotatably installed to the outside of the vertical shaft 10 fixed perpendicularly to the ground, and the plate-shaped rudder 15 is rotatably installed via the bearing 16 on the outer circumferential surface of the sleeve 12. . In order to increase power generation efficiency in such a wind generator, a method of attaching a blade to a structure or improving a pitch angle of the blade is designed to minimize angular velocity fluctuation according to wind speed. The present invention seeks to achieve the same purpose in a different manner than in the prior art.

According to the present invention, the blade 20 formed in a curved shape having a radius of curvature is fixed radially to cooperate with the sleeve 12. The blade 20 is radially fixed to the outer circumferential surface of the sleeve 12 and integrally rotates, and a generator 25 is connected to the lower end of the sleeve 12 via a gear 26. Therefore, when the blade 20 and the sleeve 12 are rotated by the wind, power is generated in the generator 25.

At this time, the blade 20 of the present invention is formed in a form that the radius of curvature decreases toward the upper side. That is, it is good not to form a simple flat plate like FIG. 2, but to have a form having a curved portion 20a that is partially rolled like a pinwheel. Of course, it does not need to be bent more than 360 ㅀ like a pinwheel, and the radius of curvature gradually becomes smaller as it goes upward. According to such a configuration, the wind is rotated while moving upwards by hitting the blade 20, thereby increasing the amount of impact due to the rotation moment, consequently contributing to the improvement of power generation efficiency.

In addition, according to the present invention, a windproof means 30 having a windshield 34 on at least one surface thereof is rotatably installed on the sleeve 12 to surround the blade 20. Wind-proof means 30 is provided with a frame 32 formed of a cylindrical skeleton as a base body. The frame 32 of the windbreak means 30 is rotatably mounted to the lower end of the rudder 15 via a bearing 36. That is, the rudder 15 and the frame 32 are rotatably independent of the sleeve 12 although they are installed coaxially with the sleeve 12.

 At this time, on the frame 32 of the wind-proof means 30 is provided with a windshield 34 to block the 20-30% range of the circumferential surface. The windbreak plate 34 is formed in an arc shape having a constant curvature and is fixed to the circumferential surface of the frame 32 having a cylindrical skeleton. The windshield 34 may have a size covering approximately 1/4 of the entire circumferential surface. If the windbreak plate 34 is too small, it is difficult to guarantee the speed adjusting function of the blade 20. On the contrary, if the windshield 34 is too large, the amount of wind reaching the blade 20 is small, and the amount of power generation and power generation efficiency are drastically reduced.

In addition, according to the present invention, the connecting means 40 is provided to allow relative position variation between the rudder 15 and the windbreak means 30. The connecting means 40 of the present invention as described above is a wire 45 is fixed to the left and right sides of the rudder 15, the winding roll 46 is rotatably installed to wind the respective wire 45, Each of the take-up rolls 46 is provided with a gear 47 which is installed to interlock with each other, and a motor 48 connected to the take-up roll 46 of the one side.

More specifically, a pair of winding rolls 46 arranged in parallel are rotatably installed on the frame 32 of the windbreak means 30. The pair of take-up rolls 46 is engaged with the gear 47, and the motor 48 is connected to the take-up roll 46 on one side. Each roller 42 is rotatably mounted on the frame 32 at equal distances from the left and right sides of the take-up roll 46. The wire 45 on one side is wound on the winding roll 46 on one side via the roller 42 at the corresponding position in one direction of the rudder 15, and the wire 45 on the other side is positioned in the other direction of the rudder 15. It is wound by the winding roll 46 of the other side via the roller 42 of this.

According to this configuration, when the motor 48 is energized and rotates in one direction, the wire 45 is wound around the winding roll 46 on one side and the wire 45 is released on the winding roll 46 on the other side. ) Changes relative positions of the windbreak means 30 with respect to the frame 32 and the windshield 34. When the energization of the motor 48 is released, the relative positions of the rudder 15 and the windbreak means 30 are kept in a changed state. The motor 48 preferably uses a servo motor or stepping motor having a low speed and high torque performance.

In addition, according to the present invention is provided with a control means 50 is electrically connected to the connection means 40 to provide an output according to the change of the signal of the wind speed sensor 55. The control means 50 is installed on the rudder 15 or the frame 32 including the wind speed sensor 55. The cable 52 for supplying power to the control means 50 is connected via a rotary connector 54 at the top of the vertical shaft 10 and the sleeve 12. The rotary connector 54 is in the form of contacting the conductive disc up and down, and the power supply from the generator 25 is not interrupted even when the blade 20 and the sleeve 12 are rotated.

6a to 6c are exemplary views showing the operation according to the present invention when changing from a weak wind to a strong wind.

In operation, when the motor 48 is driven in the forward or reverse direction according to the output signal of the control means 50, the rudder 15 is at the center position of the windshield 34 or the eccentric position spaced apart from the center of the windshield 34. You can go to When the weak wind of 8-10 ㎧ is sensed by the wind speed sensor 55, the rudder 15 is maintained at the eccentric position of the windshield 34 as shown in FIG. 6A, thereby increasing the amount of air passing through the blade 20. On the other hand, when a strong wind of 25 s or more per second is detected, the rudder 15 is controlled to be at the center position of the windshield 34 as shown in FIG. 6C, so that the flow path to the blade 20 is blocked to stop or stop. 6B shows the positional relationship between the rudder 15 and the windbreak plate 34 at the boundary area between the weak wind and the strong wind.

Of course, it is preferable that the winding range of the wire 45 through the connecting means 40 of the present invention is determined through experimental demonstration that it is associated with main part dimensions such as the rudder 15, the windshield 34, and the blade 20. Do.

It is apparent to those skilled in the art that the present invention is not limited to the described embodiments, and that various modifications and variations can be made without departing from the spirit and scope of the present invention. Therefore, such modifications or variations will have to belong to the claims of the present invention.
