Description

Technical Field

[0001] The utility model belongs to the technical field of wind turbine filter screens, and in particular relates to a self-cleaning wind turbine filter screen. Background Art

[0002] A wind turbine converts wind energy into mechanical work, which drives the rotor to rotate. The speed of rotation is then increased through a gearbox. The generator rotates and generates electricity driven by the wind wheel shaft. The gearbox will emit a large amount of heat when in use, and a radiator is required to dissipate the heat from the gearbox. In areas with severe air pollution, dust easily enters the filter in the radiator, requiring personnel to clean it regularly.

[0003] For example, the Chinese patent with the publication number CN219549045U discloses a self-cleaning wind turbine filter, including an air inlet pipe, a mounting plate fixedly connected to the inside of the air inlet pipe, two symmetrically arranged filters fixedly embedded on the mounting plate, a rotating tube rotatably connected to the center of the mounting plate, two dust-sweeping brush rods in contact with the outer surface of the filter connected to the side wall of the rotating tube, two jet pipes facing the inner surface of the filter connected to the side wall of the rotating tube, a nozzle provided on the side wall of the jet pipe, an end of the rotating tube located inside the air inlet pipe connected to a pumping mechanism, and a rotating mechanism connected to the rotating tube inside the air inlet pipe. The utility model can coordinate the dust blowing inside the filter with the dust sweeping outside the filter, so that the dust removal is more efficient and the dust removal effect of the filter is improved.

[0004] The above patent has the following problems:

[0005] This patent has some disadvantages when used, such as: when cleaning the filter, this device can only sweep away the stubborn dust on the outside of the filter, and stubborn dust will also be generated on the inside of the filter after long-term use, so that this device cannot clean the stubborn dust on the inside of the filter. In addition, when the air inlet pipe is exposed to the outside, birds may stay in the air inlet pipe, and the dust sweeping brush rod will cause harm to the birds when rotating to sweep the dust, which is not conducive to protecting the birds. In view of this, we propose a self-cleaning wind turbine filter. Utility Model Content

Under the action of the rotation of the four cleaning brushes and their own rotation, the stubborn dust on the top and bottom surfaces of the filter body can be swept off, ensuring that the stubborn dust on the top and bottom surfaces of the filter body can be cleaned.
