Description

Technical Field

[0002] In the field of wind power generation, wind turbines need to track wind direction at all times during normal operation. During yaw, the yaw brake caliper must retain pressure band damping for yaw. This causes the yaw brake pad to produce a large amount of wear products during the friction with the brake disc, and the wear products are scattered on the yaw platform. Above the yaw system are the hydraulic system and speed increase system of the wind turbine. If gear oil or hydraulic oil is scattered on the platform and mixed with the wear products, it will bring difficulties to subsequent cleaning and maintenance work and add a lot of work.

[0003] The falling position of wear materials is mainly concentrated around the yaw brake pad, but some wear materials left on the surface of the brake disc will enter the groove between the brake disc and the yaw gear ring after being pushed by the yaw brake pad. Over time, a large amount of wear materials will gather in the groove and scatter through the opening of the brake disc accompanied by the vibration of the fan.

[0037] The present application is used to collect friction dust from the fan brake pad 2 and the brake caliper. First, the collection trough 5 is driven by the L-shaped bending arm 4 to be movably inserted into the first T-shaped slide groove 3 of the positioning caliper 1, so that the collection trough 5 can be flexibly moved in multiple positions, which is convenient for adapting to the dust landing position of different fan yaw brake pads 2, and the fan yaw brake dust falls on the collection trough 5 and then slides to the movable component 6 on the side close to the L-shaped bending arm 4 through the inclined setting of the collection trough 5, which is convenient for subsequent unified dust cleaning. At the same time, the scraping cleaning component 7 can scrape away part of the dust attached to the surface of the collection trough 5 to avoid long-term accumulation of dust on the collection trough 5.

[0038] The movable assembly 6 includes a movable bottom plate 61 hinged at the bottom of the collecting tank body 5. The movable bottom plate 61 is hingedly mounted at the bottom of the collecting tank body 5 on one side close to the L-shaped bending arm 4.
