[0002] The wind turbine tower in the wind power equipment is exposed to the natural environment for a long time, and is subject to wind, sun, rain, and even salt spray and dust. It is easy to cause the coating of the outer wall of the steel tower to be damaged, paint to fall off, and rust. After some wind turbines have been running for a period of time, lubricating grease leaks from the cabin onto the tower, and combined with dust and other debris adheres to the outer wall of the tower, forming a layer of dirt, which not only affects the appearance of the wind turbine, but also affects the safety of the wind turbine. Therefore, it is necessary to repair and clean the coating on the outer wall of the wind turbine tower in time.
