[0002] Wind energy is a new type of green energy converted from solar energy. It is environmentally friendly and renewable. In the context of a society that advocates low-carbon living all over the world, how to develop and utilize wind energy is of paramount importance. At present, the largest application of wind energy is to use it to drive wind turbines to generate electricity, as a clean alternative to existing thermal power and hydropower. According to a statistical data on China's wind power released by the Renewable Energy Professional Committee of the China Resources Comprehensive Utilization Association, by the end of 2010, China's cumulative installed capacity of wind turbines reached 41.827 million kilowatts, ranking first in the world. In the plans promulgated by our country, vigorously developing new energy represented by wind energy also occupies an important proportion.

[0003] Aerial work platforms are a type of equipment frequently used during the installation and maintenance of wind power equipment. Workers use the work platform to install and maintain wind power equipment, which not only has a low risk factor but is also more conducive to the workers' work. Existing wind power equipment work platforms are inconvenient to disassemble and assemble, and are usually set up on the supporting columns of wind power equipment all year round. Since the environment in which the wind power equipment is located is rich in wind resources, the work platform is exposed to the external environment, and a large amount of sand, gravel, leaves and other debris will accumulate over time, affecting the workers' work on the work platform, increasing the risk factor, and increasing the burden on the supporting columns of the wind power equipment. Summary of the invention

[0031] In the present invention, the cleaning brush 4 cooperates with the driving mechanism 5 to regularly control the cleaning brush 4 to move along the fence 22 of the working platform 2 to clean the bottom plate 21, and the swept dust and impurities are uniformly discharged along the waste discharge chute 211, thereby avoiding debris such as sand, gravel and leaves from affecting the work of workers on the working platform 2, making the working platform 2 safer. There is a height difference between the outlet 3 of the support column 11 and the bottom plate 21 of the working platform 2, which prevents the cleaning brush 4 from sweeping dust and debris into the support column 11 and causing the inside of the support column 11 to be blocked. By setting the ladder assembly 6, it is convenient for the operator to enter the working platform 2 from the outlet. At the same time, the ladder assembly 6 is a foldable structure, which can be folded into the outlet 3 when not in use to avoid hindering the movement of the cleaning brush 4.

[0032] Furthermore, in the present embodiment, the driving mechanism 5 includes a guide structure 51 fixedly disposed on the fence 22, a movable frame 52 being disposed on the guide structure 51, the movable frame 52 being detachably connected to the cleaning brush 4 via a connecting structure 53, the movable frame 52 drives the cleaning brush 4 to move along the guide structure 51, and the moving trajectory is a circular trajectory with the support column 11 as the center. After the cleaning brush 4 is worn and aged due to long-term use, the cleaning brush 4 can be removed and replaced.

[0033] In this embodiment, the guide structure 51 includes a mounting plate 511, on which a guide rail 512 with a T-shaped cross-section is fixedly provided. The guide rail 512 is a ring structure.
