[0029] Wind turbine tower cleaning and maintenance platform, such as Figure 1-Figure 3As shown, it includes a cleaning and maintenance lifting platform 10 for cleaning and maintaining a wind turbine tower 50. A sleeve ring 20 that is sleeved and slidably connected to the wind turbine tower 50 is installed on one side of the cleaning and maintenance lifting platform 10. A lifting screw 30 that is parallel to the wind turbine tower 50 is installed on the sleeve ring 20; the sleeve ring 20 includes two groups of spliced ​​first half rings 21 and second half rings 22. Both ends of the first half ring 21 and the second half ring 22 are equipped with connecting ears 26. The connecting ears on each side of the first half ring 21 and the second half ring 22 26 are connected by at least two sets of locking bolts 27. A lifting seat 24 is installed in the middle of the outer wall of the second half ring 22. A screw hole 25 that is adapted to the size of the lifting screw 30 and is threadedly connected is opened at the center of the lifting seat 24. The bottom and top of the lifting screw 30 are respectively fixedly connected to the base 31 and the top seat 32 on the outer ring wall of the wind turbine tower 50. The bottom of the base 31 is installed with a servo motor 41 for driving the lifting screw 30. Through the cleaning and maintenance lifting platform 10 provided, the wind turbine tower 5 0 provides an operating platform for cleaning and maintenance; the sleeve ring 20 is sleeved and slid on the wind turbine tower 50, providing support and guidance for the lifting and lowering of the cleaning and maintenance lifting platform 10; the sleeve ring 20 is composed of a first half ring 21 and a second half ring 22. The connecting ears 26 and locking bolts 27 at both ends make the sleeve ring 20 easy to install and disassemble, and can be quickly assembled on the wind turbine tower 50 as needed; the lifting seat 24 in the middle of the outer wall of the second half ring 22 and the screw hole 25 thereon that is adapted to the size of the lifting screw 30 and threadedly connected enable the sleeve ring 20 to be stably raised and lowered under the drive of the lifting screw 30; the bottom and top of the lifting screw 30 are respectively fixedly connected to the base 31 and the top seat 32 on the outer ring wall of the wind turbine tower 50, ensuring the stability of the lifting screw 30; the servo motor 41 at the bottom of the base 31 can accurately drive the lifting screw 30 to rotate, thereby achieving smooth raising and lowering of the cleaning and maintenance lifting platform 10 on the wind turbine tower 50, providing convenience for tower cleaning and maintenance work.

[0030] Furthermore, an operating cabin 11 for operators to stand is provided on the top surface of the cleaning and maintenance lifting platform 10. Through the provided operating cabin 11, operators can effectively avoid the risks brought by high-altitude operations, such as falling or losing balance, when performing cleaning and maintenance operations.

[0031] Specifically, a clamping seat 12 is provided at one end portion of the cleaning and maintenance lifting platform 10 connected to the first half ring 21, and a clamping groove 23 which is adapted to the cross-sectional size of the clamping seat 12 and is clamped together is provided on the outer wall of the first half ring 21. The cross-sections of the clamping seat 12 and the clamping groove 23 are convex-shaped, and the clamping seat 12 and the clamping groove 23 are connected by a fixing bolt 13, which ensures that the connection between the lifting platform and the sleeve ring remains stable at all times during operation, and effectively prevents accidental falling off due to vibration or external force.

[0032] It is worth noting that the base 31 and the top seat 32 are both welded to the outer wall of the wind turbine tower 50 , and can withstand the huge pulling force generated during the lifting process, and can also effectively resist external environmental factors.

[0033] In addition, a motor housing 40 for protection is provided on the outer wall of the servo motor 41, which can prevent impurities such as dust and moisture from entering the interior of the motor, thereby protecting the motor from damage.

[0034] The working principle of this wind turbine tower cleaning and maintenance platform:

[0035] First, the first half ring 21 and the second half ring 22 of the sleeve ring 20 are spliced ​​around the wind turbine tower 50 so that the connecting ears 26 at both ends of the first half ring 21 and the second half ring 22 are aligned. Then, the connecting ears 26 are fixedly connected using the locking bolts 27, thereby installing the sleeve ring 20 on the wind turbine tower 50.

[0036] Next, the bottom of the lifting screw 30 is fixedly connected to the base 31, and the base 31 is fixedly mounted on the bottom of the outer ring wall of the wind turbine tower 50 via the servo motor 41. At the same time, the top of the lifting screw 30 is fixedly connected to the top seat 32, and the top seat 32 is mounted on the top of the outer ring wall of the wind turbine tower 50 to ensure that the lifting screw 30 is stable and vertical.

[0037] Then, install the cleaning and maintenance lifting platform 10 on one side of the sleeve ring 20 so that it is firmly connected to the sleeve ring 20;

[0038] When the wind turbine tower 50 needs to be cleaned and maintained, the servo motor 41 at the bottom of the base 31 is started, and the servo motor 41 drives the lifting screw 30 to rotate; since the screw hole 25 at the center of the lifting seat 24 in the middle of the outer wall of the second half ring 22 is threadedly connected to the lifting screw 30, under the rotation of the lifting screw 30, the sleeve ring 20 slides up and down along the wind turbine tower 50, thereby driving the cleaning and maintenance lifting platform 10 to move up and down, thereby realizing cleaning and maintenance work at different height positions of the wind turbine tower 50.
