If a large amount of dust is adsorbed on the components in the cabinet, it will also affect the normal operation of the components. Therefore, the existing electrical cabinet needs to be further optimized.

[0004] In this regard, the present application provides a dustproof electrical control cabinet to solve the above technical problems. Utility Model Content

[0012] Optionally, a controller and a temperature sensor are also installed on the top of the cabinet, and the controller is electrically connected to the heat dissipation box and the cylinder.

[0013] Optionally, a cleaning part is provided on the inner side of the lower end of the scraper plate, and the cleaning part is a slot opened at the lower end of the scraper plate. The cleaning plate is movably arranged in the cleaning part, and a spring connected to the inside of the cleaning part is installed on one side of the cleaning plate, and a cleaning brush extending out of the cleaning part is installed on the other side.

[0014] Compared with the prior art, the utility model has at least the following beneficial effects:

[0015] In the above scheme, thanks to the cooperation of the heat dissipation port, the dustproof net and the heat dissipation box, when the temperature inside the cabinet is too high, the exhaust fan and the ventilation fan in the heat dissipation box can be started, and the air inlet and outlet pipes can be used to evenly extract heat from the inside of the cabinet for ventilation and heat dissipation, resulting in good heat dissipation effect.

Heat dissipation ports 2 are symmetrically provided on both sides of the top of the cabinet body 1, and dustproof nets 201 are laid inside the heat dissipation ports 2, so that when ventilation and heat dissipation are performed through the heat dissipation ports 2, dust can be prevented by using the dustproof nets 201.

[0031] And cooperate Figure 4 As shown, heat dissipation boxes 3 are installed on the inner sides of the heat dissipation ports 2 on both sides, and exhaust fans 4 and ventilation fans 5 are installed separately in the heat dissipation boxes 3. An air inlet pipe 401 connected to the exhaust fan 4 and an air outlet pipe 501 connected to the ventilation fan 5 are installed at the bottom of the heat dissipation box 3.

[0033] At the same time, a cleaning plate 11 for scraping the dustproof net 201 is elastically installed on the inner side of the lower end of the scraper plate 9. In the present embodiment, during implementation, a cleaning portion 10 is provided on the inner side of the lower end of the scraper plate 9. The cleaning portion 10 is a slot provided at the lower end of the scraper plate 9. The cleaning plate 11 is movably arranged in the cleaning portion 10, and a spring 1102 connected to the inside of the cleaning portion 10 is installed on one side of the cleaning plate 11, and a cleaning brush 1101 extending out of the cleaning portion 10 is installed on the other side, so that when the scraper plate 9 moves on the side of the cabinet 1, the cleaning brush 1101 on the cleaning plate 11 can be used to elastically abut the dustproof net 201 to scrape it, thereby avoiding dust accumulation on the dustproof net 201.
