Wind power generation equipment and yawing driving mechanism thereof

Abstract

The invention discloses wind power generation equipment and a yawing driving mechanism thereof. The yawing driving mechanism comprises a first deflector rod, a first pressure cylinder, a driving disk and a first sliding block, wherein the driving disk is concentrically and fixedly connected to a yawing rotary supporting inner ring of a wind driven generator, and telescopic stop blocks are arranged in the circumferential direction of the driving disk; the first sliding block is sleeved at the first end or on the middle part of the first deflector rod, one of the first sliding block and the first deflector rod is hinged at the first end of the first pressure cylinder, the other one of the first sliding block and the first deflector rod is hinged with a frame of the wind driven generator at a first hinged point, and the second end of the first pressure cylinder is hinged with the frame; the first pressure cylinder acts on the first deflector rod, and the second end of the first deflector rod acts on the stop blocks; and when the first pressure cylinder stretches, the first deflector rod acts on the stop blocks to pull the driving disk to rotate according to the predetermined direction. Under the same power condition, the yawing driving mechanism has the advantages of higher transfer force, lower manufacturing cost, lighter weight, lower fault rate and better maintainability.

Description

technical field [0001] The invention relates to the technical field of yaw in wind power generation, in particular to a yaw driving mechanism. The invention also relates to a wind power plant comprising the above-mentioned yaw drive mechanism. Background technique [0002] Wind power generation usually converts the wind energy intercepted in the windward swept area of ​​the fan blades into electrical energy. In the actual power generation process, since the direction of the wind is constantly changing and the wind force is not stable, it is necessary to make the wind rotor of the wind power generation equipment always face the maximum direction of the wind. This function is realized through the wind turbine yaw system. [0003] The wind turbine yaw system is mainly composed of four parts: yaw measurement, yaw control, yaw drive and yaw brake. Among them, the yaw drive system mainly accepts the command of the yaw control system, and drives the yaw slewing support inner and...
