Problems solved by technology

It can reasonably distribute electric energy and facilitate the opening and closing operation of the circuit, and the existing power distribution cabinets are equipped with cooling fans to dissipate heat from their internal electrical components, and the cooling fans need to make the air flow inside and outside the cabinet, and the existing The power distribution cabinet is equipped with a filter chip to filter the flowing air entering the cabinet to prevent the dust in the outside air from entering the cabinet and adhering to the electrical components to cause circuit breaks or damage equipment. However, the existing filter chips are generally in the cabinet. After a period of use, a large amount of dust will adhere to the surface to form a dust layer, which will increase the air intake resistance and reduce the air permeability, which will affect the heat dissipation. Generally, it is necessary to manually clean the surface of the filter chip regularly to restore its ventilation performance. It is very inconvenient to prevent heat dissipation from being affected, so it is now necessary to design a self-cleaning air-filtering and dust-proof power distribution cabinet

Abstract

The invention discloses an air filtering dust prevention power distribution cabinet capable of achieving automatic cleaning. The power distribution cabinet includes a cabinet body, wherein the cabinetbody is internally fixedly connected with a fixed board, the cabinet body is divided by the fixed board into a device chamber and an air filtering chamber from up to down, the air filtering chamber is internally provided with a dust bucket in communication with the external part, a lower end of the dust bucket is connected with a sealing cover, a lower end of the cabinet body is provided with anair inlet, the air inlet is internally provided with an air fan, the fixed board is embedded with two filtering core plates, the fixed board is vertically provided with a rotation shaft in a rotationconnection in a penetration mode, a lower end of the rotation shaft is fixedly connected with a brush rod in contact with the filtering core plates, an upper end of the rotation shaft is fixedly connected with an impeller, and the impeller and the rotation shaft are coaxially arranged. The power distribution cabinet is advantaged in that automatic dust cleaning is completed after the dust is accumulated and attached to a surface of the filtering core plates operating for the long time, a knocking mechanism is used for assisting in removing the dust, and the de-dusting effect is improved.

Description
