[0022] The technical solution of this utility model will be further described in detail below with reference to specific embodiments.

[0023] In the description of this utility model, it should be noted that the terms "inner", "outer", "upper", "lower", "horizontal", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0024] like Figures 1 to 8As shown, the wind turbine tower cleaning robot of this invention includes a T-shaped vehicle body 10. One or two omnidirectional wheels 12 are provided at the rear of the vehicle body 10. A crossbeam 14 is transversely arranged at the front of the vehicle body 10. A pivot shaft 16 is symmetrically arranged at each end of the crossbeam 14. A housing 18 is pivotally mounted on each pivot shaft 16. A drive wheel 20 is arranged on each side of the housing 18. A motor (not shown) is installed inside the housing 18 to drive the drive wheels 20 to rotate. When this invention travels on a curved surface, the housing 18 will deflect according to the curvature of the travel surface, thereby ensuring that the drive wheels 20 on both sides can always remain in close contact with the travel surface.

[0025] A U-shaped bracket 22 is detachably mounted on the vehicle body 10. A left-right swing motor 24 is mounted on the U-shaped bracket 22. A base 26 is mounted on the output shaft of the left-right swing motor 24. A pitch swing motor 28 is mounted on the base 26. A longitudinal support arm 30 is mounted on the output shaft of the pitch swing motor 28. Several clamps 32 for holding high-pressure water or high-pressure air pipes are mounted on the top of the support arm 30. The swing angle of the left-right swing motor 24 is -43° to 43°. Two left-right swing limit blocks 34 are provided on the U-shaped bracket 22 to limit the left-right swing motor 24. The swing angle of the pitch swing motor 28 is 0° to 90°. Two pitch swing limit blocks 36 are provided on the base 26 to limit the pitch swing motor 28. With this structure, the support arm 30 can swing left and right and up and down, expanding the cleaning range. A water pump or air pump is installed on the ground to supply water, and the nozzles of the water or air pipes are fixed on the clamp 32, so that water washing, blowing, or sandblasting can be performed as the support arm 30 swings. In some water-scarce application scenarios, using high-pressure air blowing or sandblasting is also a resource-saving cleaning method.

[0026] Several permanent magnets 38 are installed at the bottom of the vehicle body 10. All permanent magnets 38 are arc-shaped structures with their curved surfaces facing downwards, and are respectively located at the front and rear of the vehicle body 10. The permanent magnets 38 allow the vehicle body 10 to adhere to the wind turbine tower, enabling vertical movement. The arc-shaped structure of the permanent magnets 38 helps to maintain close proximity to the wind turbine tower without interfering with its structural components or hindering movement.

[0027] A camera (not shown) is installed on the boom 30 to allow users to observe the condition of the wind turbine tower from the ground and to judge the cleaning area and cleaning effect.

[0028] Both boxes 18 are equipped with hooks 40, which can be used for hoisting and moving with lifting equipment during transportation, and can also be protected by safety ropes during operation.

[0029] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
