[0002] Wind turbines are electrical equipment that convert wind energy into mechanical work and ultimately output alternating current. They are clean, renewable, and pollution-free. They are currently one of the fastest growing renewable energy sources in the world. With the advancement of technology, the cost of wind power generation has gradually decreased and has become an important source of electricity.

[0003] The blades of wind turbines are one of the most important components in a wind power generation system. They are usually made of composite materials such as glass fiber or carbon fiber plastic to reduce weight and increase strength and durability. The blades of large commercial wind turbines can range from tens of meters to hundreds of meters in length.

[0004] When wind turbines are used for a long time, a lot of oil, dust and dirt will accumulate on the blades. Therefore, regular cleaning and maintenance of the blades is an important maintenance task. The existing cleaning method is to manually climb onto the blades to clean them one by one. The hanging cleaning method lacks a fulcrum and the cleaning operation is more difficult. Climbing and cleaning multiple groups of blades in turn is time-consuming and labor-intensive, and there are also major safety hazards. Utility Model Content

[0026] Embodiment 2

[0027] Based on the first embodiment, Figure 4 As shown, the driving structure 4 includes a support frame 10, a driving shaft 11 and a driving motor 12. The support frame 10 is arranged at the bottom of the cabin of the wind power tower 1, and the driving shaft 11 is rotatably arranged on the opposite side wall of the support frame 10. The driving motor 12 is arranged on one side of the support frame 10 and the power output shaft is connected to the driving shaft 11. Two groups of steel wire ropes 13 are wound around the driving shaft 11. A connecting ear 14 is provided on the top of the support plate 5. The steel wire rope 13 is wound and connected with the connecting ear 14. The driving structure 4 is symmetrically provided with two groups.
