Clearing device, and wind power generator set and yaw system thereof

Abstract

The application provides a clearing device, and a wind power generator set and a yaw system thereof. The clearing device is used for clearing attachments on a first component, and comprises a base seat, at least one pressure applying part and at least one clearing assembly, wherein the at least one clearing assembly is in sliding fit with the base seat, the at least one pressure applying part haselasticity, one end of each pressure applying part is arranged on the base seat, one end of each clearing assembly is butted against or connected with the other end of each corresponding pressure applying part, and the other end of each clearing assembly exceeds the base seat, and used for butting against the first component under elasticity effect of each pressure applying part. The clearing device can timely and effectively remove attachments on a brake disc and / or a friction plate, guarantees that the yaw system in the wind power generator set can stably run in a good state, improves executing stability of yaw maneuver for the wind power generator set, and simultaneously reduces worn risk of the friction plate and the brake disc, and prolongs use life of the frication plate and the brake disc. The clearing device does not need to additionally arrange energy dissipation units, reduces design cost, and improves reliability.

Description

technical field [0001] The present application relates to the technical field of braking systems, in particular, to a clearing device, a wind power generating set and a yaw system thereof. Background technique [0002] In some mechanical systems with a braking function, the friction force generated after the friction plate in the brake contacts with the brake disc is generally used to achieve braking. During the working process of the system, the friction lining and the brake disc are prone to produce attachments, which will have a negative impact on the performance of the braking system. [0003] Taking the yaw system in the wind turbine unit (referred to as the fan) as an example, a hydraulic device is installed in the brake, and the hydraulic device is used to drive the friction plate to contact the brake disc to slow down or stop the yaw action of the fan. During the operation of the wind turbine, various factors will cause deposits on the friction lining and the brake ...

AI Technical Summary

Problems solved by technology

The glaze layer is often uneven, and the consistency of the material is poor, which will greatly affect the stability of the yaw action, and will accelerate the wear of the friction plate, resulting in additional high noise

[0004] In the prior art, there is a lack of devices capable of effectively removing deposits on friction linings and / or brake discs
