Technical Field
[0001] The utility model relates to the technical field of wind turbine accessories, in particular to a self-cleaning filter screen for wind turbines. Background Technique
[0002] With the continuous growth of the global demand for renewable energy, wind power generation, as a clean and renewable energy form, has become increasingly important. As the core component of the wind power generation system, the operating efficiency and reliability of wind turbines directly affect the power generation capacity and economic benefits of the entire system. However, during the operation of wind turbines, especially in areas with relatively serious air pollution, a large amount of polluting particulate matters such as dust and catkins often quickly accumulate on the filter screen at the air inlet, resulting in the blockage of the filter screen, affecting the ventilation effect and heat dissipation efficiency of the wind turbine, and further causing problems such as a decrease in the unit power, overheating, and even shutdown. The traditional filter screen of wind turbines needs to be manually cleaned regularly, which not only consumes a large amount of manpower and time, but also increases the maintenance cost of wind turbines.

[0016] 2. In this self-cleaning wind turbine filter, bearings for fixing the lead screw are embedded on the inner walls at both ends of the connecting housing, reducing the friction and resistance during the rotation of the lead screw, ensuring the smoothness and accuracy when the reciprocating motor drives the lead screw, and thus ensuring that the self-cleaning seat can move smoothly and accurately along the lead screw to complete the cleaning task.
[0017] 3. In this self-cleaning wind turbine filter, a connecting strip is provided at the top of the cleaning brush bristles, and the connecting strip is connected to the bottom sides of both sides of the self-cleaning seat by fixing bolts.

[0028] Self-cleaning wind turbine filter, such as Figures 1-3As shown in the figure, it includes a connection housing 10 installed at the bottom of a wind turbine. A filter screen layer 20 is installed at the bottom of the connection housing 10. A lead screw 30 is installed inside the connection housing 10, and a self-cleaning seat 40 is installed on the lead screw 30. A reciprocating motor 31 for driving the lead screw 30 to rotate is installed on the outer wall of one end of the connection housing 10. A hollow area 43 is provided inside the self-cleaning seat 40. Cleaning brushes 41 are symmetrically arranged on both sides of the bottom of the self-cleaning seat 40. Air jet holes 45 communicating with the inside of the hollow area 43 are provided on the bottom surface of the self-cleaning seat 40. An air pump 42 is installed on the outer wall of one side of the self-cleaning seat 40, and the air outlet of the air pump 42 is communicated with the inside of the hollow area 43. By providing the connection housing 10, an installation foundation and a support structure are provided for the entire self-cleaning wind turbine filter. The filter screen layer 20 installed at the bottom of the connection housing 10 can effectively filter the air entering the wind turbine and prevent impurities from entering and damaging the unit. The lead screw 30 installed inside the connection housing 10 rotates driven by the reciprocating motor 31, providing power for the movement of the self-cleaning seat 40. The hollow area 43 provided inside the self-cleaning seat 40 provides space for the storage and circulation of gas. The cleaning brushes 41 symmetrically arranged on both sides of the bottom of the self-cleaning seat 40 can clean the filter screen layer 20 during the movement of the self-cleaning seat 40 and remove impurities attached to the filter screen. The air jet holes 45 provided on the bottom surface of the self-cleaning seat 40 and communicating with the inside of the hollow area 43, and the air pump 42 installed on the outer wall of one side of the self-cleaning seat 40, with the air outlet of the air pump 42 communicated with the inside of the hollow area 43, enable the air pump 42 to inflate the hollow area 43, and the gas is ejected through the air jet holes 45, further assisting the cleaning brushes 41 to clean the filter screen layer 20 and improving the cleaning effect.
[0029] Furthermore, a connection seat 11 for assembling with the bottom of the wind turbine is installed at the top edge of the connection housing 10. Installation holes 12 are provided at the four top corners of the connection seat 11, enabling the entire self-cleaning filter screen system to be stably and conveniently installed at the bottom of the wind turbine.
[0030] Among them, bearings 13 for fixing the lead screw 30 are embedded on the inner walls at both ends of the connection housing 10, reducing the friction and resistance during the rotation of the lead screw 30, ensuring the smoothness and accuracy when the reciprocating motor 31 drives the lead screw 30, and thus ensuring that the self-cleaning seat 40 can move smoothly and accurately along the lead screw 30 to complete the cleaning task.
[0031] It is worth noting that the length of the cleaning brushes 41 is greater than the distance between the self-cleaning seat 40 and the filter screen layer 20, ensuring that the cleaning brushes 41 can fully contact the surface of the filter screen layer 20 during the movement of the self-cleaning seat 40.
[0032] Specifically, a protective housing 32 is provided on the outer wall of the reciprocating motor 31, which can effectively prevent external impurities such as dust and moisture from entering the interior of the motor, protect the motor from damage, and extend its service life.

The connecting strip 46 is connected to the bottom sides of both sides of the self-cleaning seat 40 by fixing bolts. When the cleaning brush bristles 41 are worn or need to be replaced, only by loosening the fixing bolts, the connecting strip 46 and the cleaning brush bristles 41 can be easily removed for replacement or repair, improving the maintainability and service life of the equipment.
[0034] It should be noted that both ends of the self-cleaning seat 40 are slidably engaged with the inner walls on both sides of the connecting housing 10, reducing the friction and resistance during the movement process, improving the cleaning efficiency, and at the same time ensuring the stability and accuracy of the self-cleaning seat 40 during the movement process.
[0035] The working principle of this self-cleaning wind turbine filter:
[0036] First of all, the installer installs the connecting housing 10 at the bottom of the wind turbine. The connecting housing 10 provides an installation foundation and a support structure for the entire filter system; a filter mesh layer 20 is installed at the bottom of the connecting housing 10. During the operation of the wind turbine, the filter mesh layer 20 effectively filters the air entering the wind turbine to prevent impurities from entering and damaging the unit;
[0037] When the filter mesh layer 20 needs to be cleaned, the reciprocating motor 31 on the outer wall of one end of the connecting housing 10 is started, and the reciprocating motor 31 drives the lead screw 30 inside the connecting housing 10 to rotate; the rotation of the lead screw 30 provides power for the movement of the self-cleaning seat 40 installed thereon;
[0038] During the movement of the self-cleaning seat 40, the cleaning brush bristles 41 symmetrically arranged on both sides of its bottom clean the filter mesh layer 20 to remove the impurities attached to the filter mesh; at the same time, the air pump 42 installed on the outer wall of one side of the self-cleaning seat 40 is started, and the air pump 42 inflates the hollow area 43 opened inside the self-cleaning seat 40; the gas is ejected through the air jet holes 45 opened on the bottom surface of the self-cleaning seat 40 and connected to the inside of the hollow area 43, further assisting the cleaning brush bristles 41 to clean the filter mesh layer 20 and improving the cleaning effect.
