Embodiment 1
[0015] Such as figure 1 , 2, the passive variable pitch wind power generator described in this embodiment includes fan blade 1, fan blade connecting handle 2, hub spoke tube 3, crank 4, synchronous disk 5, motor shaft 6, pull rod 7, wind The blade 1 is installed on the fan blade connecting handle 2, and the fan blade connecting handle 2 is connected with the hub spoke tube 3 through the bearing 8, and can rotate relatively. The root of the fan blade connecting handle 2 is connected with the crank 4 by a key, and the crank 4 is connected with the synchronous disk 5 through the interlocking structure composed of three connecting rods 20 and six joint bearings, so that the rotary motion of the fan blade connecting handle 2 is converted into a synchronous Reciprocating motion of disc 5. The synchronous disk 5 and the pull rod 7 passing through the hollow motor shaft 6 adopt a flat key to cooperate, and the pull rod 7 is provided with bolts to fix the pull rod 7 and the synchronou...
Embodiment 2
[0017] As shown in Figure 3, the passive variable pitch wind power generator described in this embodiment is based on Embodiment 1. A spring gland 10 is provided at one end of the pull rod 7, and a spring gland 10 is provided between the motor shaft 6 and the spring gland 10. There is a spring 11, and a damper 12 is arranged inside the spring 11. The elastic force generated by the deformation of the spring 11 forms a pair of balance forces through the centrifugal force of the pull rod 7, the concentric disk 5, the crank 4, the blade connecting handle 2 and the centrifugal hammer 9. When the wind speed decreases Small, when the rotation speed of fan blade 1 slows down and the centrifugal force of centrifugal hammer 9 decreases, the angle of fan blade 1 is automatically reset by the elastic force of spring 11, and the compression and reset of spring 11 are restricted by damper 12, which can eliminate excessive wind speed The change results in vibrations from frequent pitch change...
