A wind turbine yaw device

Abstract

The invention belongs to the field of wind power generators, and in particular relates to a yaw device for wind power generators. The bottom of the bracket in the equipment box is fixedly equipped with an annular internal rack, and the bottom of the annular internal rack is provided with a limit assembly. The yaw assembly is connected, the top of the bracket is fixedly installed on the bottom inner wall of the unmooring chamber, and the unmooring motor is fixedly installed on the inner wall of the bottom of the unmooring chamber. The uncable shaft is fixedly installed, and the top of the uncable shaft is fixedly installed with a clamping plate. The top of the uncable shaft is rotated and installed with a yaw shaft. The top of the yaw shaft runs through the top of the equipment box and extends to the top of the equipment box. One side of the yaw axis is fixedly installed on the inner wall of the clamping block, and the drive shaft is rotatably installed. The yaw device takes less time to untwist and has high efficiency. The yaw axis after yaw can be braked, and the stability and High reliability.

Description

technical field [0001] The invention belongs to the field of wind power generators, and relates to a wind power generator yaw device. Background technique [0002] A wind turbine is a power device that converts wind energy into mechanical work, which drives the rotor to rotate, and finally outputs alternating current. A wind turbine generally includes a wind wheel, a generator (including devices), a steering device (tail), a tower, and a limiter. The working principle of the wind turbine is relatively simple. The wind rotor rotates under the action of the wind. It converts the kinetic energy of the wind into the mechanical energy of the wind rotor shaft, and the generator rotates under the drive of the wind rotor shaft. generate electricity. [0003] The yaw device of the existing wind turbine cannot brake the yaw axis after yaw, resulting in the position stability of the yaw axis is not high, the cable is directly wound on the yaw axis, when the yaw axis When there are to...

AI Technical Summary

Problems solved by technology

[0004] In view of this, in order to solve the problem that the traditional yaw device of the wind power generator cannot brake the yaw axis after yaw, the position stability of the yaw axis is not high, and the cable is directly wound around the yaw axis In the above, when too many cables are wound on the yaw axis, it is necessary to untie the cable and then carry out the yaw operation, which takes a long time to untie the cable, which affects the working efficiency of the wind turbine, and provides a wind turbine yaw device
