In wind turbine units, there is still friction between the brake pads and brake discs installed in the brake calipers. The powder generated by the wear of the brake pads will fall onto the yaw platform. The powder needs to be collected, otherwise it will pollute the platform and be inconvenient to clean later.

[0003] The utility model patent with application number "202321701543.7" proposes a technical solution that "includes a powder collection tank bracket (2) and a powder collection tank (4), wherein the powder collection tank bracket is fixed to the brake caliper by the fixing bolt of the brake caliper (1), two springs (3) are fixed at the bottom of the powder collection tank bracket, the top of the springs is fixed to the powder collection tank, and a limit switch (6) is fixed on the side of the powder collection tank bracket near the bottom." The powder collection box is directly installed by the spring, which is inconvenient to disassemble and the spring is not limited. Generally, the spring will become fatigued after long-term use, which will affect the overall performance. Utility Model Content
