The filter guide 42 installed outside the double-head connector 41 and the connecting pipe 44 is connected with the flow-through cavity 8. By installing multiple groups of filter guides 42, the range of air transportation is expanded, and the cooling efficiency is improved.

[0058] The filtered air is delivered into the air inlet of the flow guide cover 422 through the double-end connector 41 and the connecting pipe 44, and the flexible scraper belt 426 installed in the air inlet of the flow guide cover 422 swings in the flow guide cover 422 by the air flow generated by the air flow to clean the dust and flocculent impurities adhered to the surface of the filter plate 425. The flexible scraper belt 426 is made of nylon ribbon material, and the length thereof can be cut according to the size of the filter plate 425, and the flexible scraper belt 426 is fixed in the air flow channel of the flow guide cover 422 through the buckle 427, so that the flexible scraper belt 426 can be easily disassembled and replaced. The flexible scraper belt 426 made of ribbon material is relatively soft, and when the flexible scraper belt 426 is in contact with the filter plate 425, the flexible scraper belt 426 is in elastic friction, so that the dust and fibers adhered to the surface can be effectively cleaned, and the wear and tear of the filter plate 425 caused by the traditional metal scraper or hard brush can be avoided.

[0059] When the switch cabinet is in the running state, the flexible scraper belt 426 can continuously clean the filter plate 425 dynamically, so that the ventilation of the filter plate 425 is stably maintained, the heat dissipation efficiency of the electrical elements in the switch cabinet is maintained, and the accuracy of temperature monitoring and data transmission is indirectly guaranteed.

[0060] When the flexible scraper belt 426 swings in the flow guide cover 422 driven by the air flow, the flexible scraper belt 426 is in contact with the surface of the friction ball 451. In the process of cleaning and swinging of the flexible scraper belt 426 on the filter plate 425, part of the dust and fibers adhered to the surface of the flexible scraper belt 426, if accumulated for a long time, may fall again to the filter plate or enter the cabinet body 3 due to the swinging of the flexible scraper belt 426, thereby causing secondary pollution. When the flexible scraper belt 426 collides with the friction ball 451, the vibration of the flexible scraper belt 426 and the physical impact of the friction ball 451 can shake off the adhered dust to the bottom of the flow guide cover 422, so that the dust on the surface of the flexible scraper belt 426 can be cleaned to avoid the decrease of the swinging activity of the ribbon due to the weight.
