Move toward rod 1 5. When in use, since the wind turbine gearbox will generate more heat when working, a heat dissipation device is often required for heat dissipation treatment. In order to improve the heat dissipation efficiency and service life of the heat dissipation device, a filter is usually required to be arranged on the heat dissipation device to filter the floating dust in the air. After long-term use, the wrinkled surface of the filter will produce more dust. Therefore, the dust removal component 4 needs to be driven by the power component to move to the bottom of the dustproof filter 3, and then the dust removal component 4 is used to clean the dust in an orderly manner along the wrinkle direction of the dustproof filter 3. After the cleaning is completed, the dust removal component 4 determines the position of the protective component 9 through the positioning component and moves it to the inside, so that the dust removal component 4 is hidden. Since the dust removal component 4 is movable, it not only improves the dust removal efficiency, but also because of its small size, it can be hidden after the dust removal is completed, thereby effectively avoiding the situation where the air outlet of the heat dissipation device body 1 is blocked.

The driving component arranged on the dust removal component 4 enables the dust removal bristles 13 on it to complete the extension into the deep of the folds of the dust filter 3, and can complete the deep cleaning operation of the deep of the folds by the left and right translation action. At the same time, due to the structure of the micro-bristles 11 being arranged on the dust removal bristles 13, multi-hair deep cleaning is achieved, and the dust after cleaning can be absorbed and collected by the absorbing component, effectively avoiding the dust from being raised during dust cleaning.

[0036] The driving assembly in the present invention includes two sleeves 19, and the two sleeves 19 are respectively sleeved on one side of the two positioning rods 21.
