And to prevent wind turbines from swinging to the left and right even during stormy winds, and to prevent damage to propeller blades during typhoons, wind pressure is automatically paralleled to the blade surface to avoid wind pressure when the wind turbine rotation exceeds a certain limit. Like that.

The internal threaded gear 10 is rotated in order to move the male threaded shaft 9 screwed therein in the axial direction, while a rack toothed square portion 8 that meshes with the fan-shaped gear 6 of the propeller blade is provided at one end. By connecting the shank connecting rod 7 through the hollow hole 21 of the common shaft 20 of the generator 18 and the wind turbine blade 1 and rotatably connecting to the male screw shaft 9, it is moved in the same axial direction as A structure in which the inclination of the blade surface of the propeller blade 4 can be changed by rotating several fan gears 6 meshed with the rack toothed square portion 8 of the connecting rod 7 while maintaining the inclination angle of the blade surface at about 45 degrees. Wind turbines operating normally increase suddenly Therefore, when the rotation of the wind turbine suddenly increases, the phenomenon that the generated voltage of the DC generator 16 of the wind turbine is increased is detected, thereby starting the motor 11 with a speed reducer and letting the blade face parallel to the wind direction to release intense wind force. In this wind power generator, the motor 11 with a speed reducer is started in the forward direction by a timer after a predetermined time has elapsed, and the blade surface is returned to the normal inclination angle of 45 degrees to return the windmill to normal operation.

Description

  The present invention relates to a wind power generator that generates power using wind power.

  There are many problems in generating electricity using natural wind. The challenge is how to effectively use the energy of the wind, which is intense and the direction of the wind constantly fluctuates, up to a typhoon that is almost unusable than the almost windless state.

  In the present invention, it is necessary to always ensure the maximum wind receiving area so that the direction can be changed in the direction of a weak wind.

  In order to prevent damage to the propeller blades during a typhoon, it is necessary to avoid the wind pressure by making the blade surfaces parallel to the typhoon.

  It is necessary to absorb this impulse and calm down in the wind direction when the windmill swings violently from side to side in the event of a strong wind and there is a risk of breakage.

  In the event of a typhoon, it is also necessary to reinforce the support in a simple way for safety.

  In the present invention, each part constituting the windmill is arranged on the support column 33 in order of the windmill control section 3, the generator section 2, and the windmill blade section 1 from the windward, and the small gear 12 attached to the motor 11 with a reduction gear is used. A long shaft provided with a rack toothed square portion 8 at one end thereof, which rotates the internally threaded gear 10 so as to move the externally threaded shaft 9 screwed in the axial direction, while meshing with the fan-shaped gear 6 of the propeller blade. This connecting rod 7 passes through the hollow hole 21 of the common shaft 20 of the generator 18 and the wind turbine blade 1 and is rotatably connected to the male screw shaft 9 and moved in the same axial direction as this. Several fan gears 6 meshing with the rack toothed square portion 8 of the connecting rod 7 are rotated so that the inclination of the blade surface of the propeller blade 4 can be changed.

  When the wind turbine operating normally with the blade surface tilt angle kept at about 45 degrees suddenly increases in speed due to a sudden increase in wind speed, it captures the phenomenon of increase in the voltage generated by the DC generator 16 of this wind turbine. A voltmeter 13 having a pointer with a contact is incorporated in the circuit, and the contact is made to bring the pointer 14 into contact with the upper limit contact 15 on the voltage indicator board, and this signal is taken out to start the motor 11 with a speed reducer in the reverse direction. The fan-shaped gear 6 is rotated counterclockwise through the female threaded gear 10, the male threaded shaft 9, and the rack-toothed square portion 8 of the connecting rod so that the blade surface is parallel to the wind direction and the intense wind force is released.

  After a certain period of time has elapsed, the motor 11 with a speed reducer is started in the forward direction by a timer, and the internal threaded gear 10 is rotated to move the external threaded shaft 9 and the rack toothed square portion 8 of the connecting rod in the leeward direction. The blade surface is returned to the normal inclination angle of 45 degrees to return the windmill to normal operation.

  The wind turbine generator yoke body 17 is fixed to the upper flange portion 26 of the support shaft 24, and the support shaft 24 is supported by the bearings 25 and 28 on the upper portion of the wind turbine support 33 to be arranged on the leeward side. It is structured such that the head swings in response to the wind, and a hydraulic anti-sway device 27 is interposed between the upper flange portion 26 of the support shaft and the wind turbine support 33, and the partition plate 32 protrudes from the support shaft 24 at the center. The oil chamber 29 inside the steadying cylinder 30 provided with a partition wall 31 in one place can be rocked and swung through the pores 34 opened in the partition wall 31. By restricting the inflow of oil from one chamber in the cylinder 30 to the other chamber, the swing of the partition plate 32 is delayed, so that the abrupt wind direction of the windmill device fixed to the support shaft 24 integrated with the partition plate 32 Alleviate the urge to change To gradually can follow the wind direction by.

By placing a generator and a windmill on the leeward side and opening a space on the windward side, draw the tensile steel wire 35 from the steel wire attachment part 36 on the upper side of the support column to several mounting piles 37 installed on the windward side. Is possible, and the risk of typhoons can be prevented.

  In the case of a typhoon, the propeller blade surface of the windmill 1 can be automatically made parallel to the wind direction to escape the wind, and the wind pressure applied to the windmill can be reduced. Accordingly, the width of the propeller blade can be increased, and the power generation capacity of the wind turbine can be increased. And it can return to normal operation automatically by the timer after passing the typhoon. This timer can also be operated by a person from a remote location.

  The windmill automatically turns in the direction of the wind even when it is weak and can receive 100% wind. Also, in the case of a strong wind, the windmill is gently swung to the left and right. It settles in the direction, receives enough wind, and can generate power efficiently.

Further, a structure capable of sufficiently supporting the reaction force due to the wind pressure of the propeller blades in order to rotate the internally threaded gear 10 by the small gear 12 of the motor 11 with speed reducer and cause the externally threaded shaft 9 screwed therein to move in the axial direction. It has become.

  When the wind turbine operating normally with the blade surface tilt angle kept at about 45 degrees suddenly increases in speed due to a sudden increase in wind speed, it captures the phenomenon of increase in the voltage generated by the DC generator 16 of this wind turbine.

  Then, after a certain period of time, the timer is operated to start the motor 11 with speed reducer in the forward rotation direction, the internal threaded gear 10 is rotated to move the external threaded shaft 9 to the leeward side, and the rack teeth of the connecting rod interlocking therewith. The angled portion 8 is moved in the same direction, and the gear 6 is rotated to the right by about 45 degrees to return the blade surface to the normal inclination angle of 45 degrees to return to normal operation as shown in FIG.

  A hydraulic anti-sway device 27 is interposed between the upper flange portion 26 of the support shaft and the wind turbine column 33, and a partition plate 32 is attached to the support shaft 24 at the center so as to protrude, and this is provided at one partition wall inside.
