[0031] The working principle and beneficial effects of the above technical solution are:

[0032] How it works

[0033] Working principle of the sliding mounting assembly 4: When the servo motor 404 is started, its output shaft drives the bidirectional lead screw 403 to rotate. Since the sliding frame 405 is symmetrically threaded with the bidirectional lead screw 403, the sliding frame 405 slides up and down along the guide rod 407. This design allows the anti-blocking cleaning mechanism 5 to move flexibly in the vertical direction to meet different cleaning needs.

[0034] Working principle of anti-blocking cleaning mechanism 5: After driving motor 1 502 is started, its output shaft drives cam 1 503 to rotate. The rotational motion of cam 1 503 is transmitted to sliding block 507 through connecting rod 1 504 and connecting rod 2 505, so that sliding block 507 slides left and right in sliding groove 1 506. The movement of sliding block 507 further drives push rod 1 508 to move left and right, thereby realizing the horizontal cleaning action of anti-blocking cleaning mechanism 5.

[0035] Beneficial Effects

[0036] High flexibility: The design of the sliding mounting assembly 4 enables the anti-blocking cleaning mechanism 5 to move flexibly in the vertical direction, thereby increasing the flexibility and coverage of cleaning.

[0037] Good cleaning effect: the anti-blocking cleaning mechanism 5 can effectively remove dirt and dust on the motor body 1 and the rotating shaft 2 through horizontal movement, prevent blockage, and improve the operating efficiency of the motor.

[0038] Compact structure: The entire mechanism is compactly designed, occupies little space, and is easy to install and use on the wind turbine pitch motor.

[0043] The working principle and beneficial effects of the above technical solution are as follows:

[0044] Working principle of the rotation adjustment mechanism 6: After the rotating motor 602 is started, its output shaft drives the worm 603 to rotate. The worm 603 and the rotating shaft 604 are meshed through gears to transmit the rotational motion to the rotating shaft 604. The rotation of the rotating shaft 604 further drives the sleeve 2 7 and the vertical rod 1 702, baffle 1 703, arc brush 705 and scraper 706 inside to rotate together. This rotation cleaning action can more comprehensively remove dirt and dust on the motor body 1.

[0045] Working principle of compressed air mechanism 8: After compressed air pump 801 is started, compressed air is delivered to air nozzle 802 through air supply hose 803.
