[0002] As a core device for power distribution and protection, power cabinets are widely used in industrial and commercial environments. A variety of electrical devices are installed inside, such as circuit protectors, contactors, circuit breakers, etc. These devices generate heat during operation.

DETAILED DESCRIPTION
[0018] The specific implementation modes of the present invention are further explained in detail below by describing the embodiments with reference to the accompanying drawings, so as to help those skilled in the art to have a more complete, accurate and in-depth understanding of the concept and technical solution of the present invention.
[0019] like Figures 1-5 As shown, the present invention provides an electric heat dissipation cabinet, comprising a cabinet body 1, a filter screen 2 and a cleaning mechanism 3. The cabinet body 1 is provided with heat dissipation holes on the side, and the filter screen 2 is installed on the heat dissipation holes. The cleaning mechanism 3 is arranged in the cabinet body 1 and cleans the filter holes of the filter screen 2 under the action of a cleaning brush 31 thereon. The length of the cleaning brush 31 is greater than the width of the filter screen 2, so that the cleaning brush 31 can clean the filter screen 2 more comprehensively.
[0020] It should be noted that the cleaning mechanism 3 includes a rotating shaft 32, a driving assembly 33, a driving disk 34 and a sliding rod 35. The rotating shaft 32 is rotatably connected to the cabinet body 1. The driving assembly 33 is arranged at the outer end of the rotating shaft 32. The driving assembly 33 includes a connecting seat 331 and blades 332. The connecting seat 331 is installed on the rotating shaft 32. A plurality of blades 332 are provided and evenly distributed along the circumference of the connecting seat 331. When the wind outside the cabinet body 1 blows the blades 332, the blades 332 drive the rotating shaft 32 to rotate, thereby driving the cleaning brush 31 to move to clean the filter screen 2. The filter screen 2 can be cleaned without an additional electric driving device, thus saving energy and cost.
[0021] The driving disk 34 is installed at the inner end of the rotating shaft 32. The sliding rod 35 is slidably connected to a fixed block 36 on the inner wall of the cabinet body 1. The cleaning brush 31 is arranged at one end of the sliding rod 35 and the bristles thereon abut against the filter screen 2. A moving frame 37 is arranged at the other end of the sliding rod 35. A sliding groove 371 is arranged on the moving frame 37. A plug rod 38 inserted into the sliding groove 371 is arranged on the driving disk 34.
[0022] In addition, an elastic piece 39 is arranged on the side surface of the driving disk 34. The length of the elastic piece 39 is greater than the distance between the fixed block 36 and the driving disk 34. When the cleaning brush 31 approaches the driving disk 34, the elastic piece 39 can better contact the cleaning brush 31 and flick the bristles thereon, so that the dust on the bristles drops off.
[0023] Specific implementation manners and principles:
[0024] During operation, when the electrical equipment in the cabinet body 1 dissipates heat, gas exchange is carried out through the filter screen 2 on the heat dissipation holes, and dust in the outside air is filtered through the filter screen 2.
[0025] When the wind outside the cabinet body 1 blows the blades 332 on the rotating shaft 32, it will drive the rotating shaft 32 to rotate. The rotating shaft 32 drives the driving disk 34 to rotate. The plug rod 38 on the driving disk 34 moves in the sliding groove 371 on the moving frame 37, so that the sliding rod 35 slides on the fixed block 36. The sliding rod 35 drives the cleaning brush 31 to move on the filter screen 2 to dredge the filter holes on the filter screen 2. While the driving disk 34 is rotating, when the elastic piece 39
[0026] on it contacts the bristles on the cleaning brush 31, the bristles are flicked, so that the dust on the bristles is flicked off. Since the elastic piece 39 is made of an elastic material, the elastic piece 39 will deform to avoid the fixed block 36, so that the elastic piece 39 flicks the bristles on the other side of the cleaning brush 31, thereby improving the cleaning effect of the cleaning brush 31.
[0027] In summary, the present application drives the blades 332 of the driving assembly 33 to rotate through the natural wind in the external environment of the cabinet 1, thereby driving the associated slide rod 35 to make the cleaning brush 31 move in a directional manner on the surface of the filter screen 2. At the same time, the device cleverly combines the elastic sheet 39 on the side of the drive disk 34 to periodically move the bristles on the cleaning brush 31, causing the dust attached to the bristles to fall off in time. This self-cleaning mechanism significantly improves the cleaning effect of the cleaning brush 31 on the filter screen 2 pores, ensuring the long-term and efficient use of the filter screen 2. The present application achieves efficient and automated maintenance of the filter screen 2 by optimizing the structural design and utilizing natural wind energy without the need for additional energy supply, and has important engineering practical value.
[0028] The above-described embodiments of the present invention do not constitute a limitation on the protection scope of the present invention. Any modification, equivalent substitution and improvement made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.
