[0002] A wind turbine is a device that converts wind energy into electrical energy, and it plays a key role in the modern renewable energy system. When the wind blows, it pushes the large blades to rotate, which are connected to the hub, and the hub is connected to the main shaft. With the rotation of the blades, the main shaft drives the gears in the gear box to rotate, thereby accelerating the rotational motion and transmitting it to the generator. The generator uses the principle of electromagnetic induction to convert mechanical energy into electrical energy, and then the electricity can be transmitted to various places through the power grid for people to use. The design of the wind turbine usually considers efficiency, reliability and environmental adaptability to ensure stable operation in various weather conditions and capture as much wind energy resources as possible.

[0003] During the operation of the wind turbine, a large amount of dust and impurities such as willow catkins commonly seen in spring will accumulate on the gear box fins of the wind turbine. This problem is particularly prominent in wind farms located in areas with more dust and frequent sandstorms. These external factors affect the normal heat dissipation performance of the gear box radiator, which adversely affects the operation of the entire wind turbine system. When the fins are covered with dust and willow catkins, they hinder the heat exchange efficiency between the air and the fins, making it difficult for the lubricating oil in the gear box to effectively dissipate heat.
