Description

Technical Field

[0001] The invention relates to the technical field of power distribution cabinets, and in particular to a dustproof and shock-resistant power distribution cabinet used in construction projects. Background Art

[0002] The distribution cabinets in the prior art are all provided with ventilation and heat dissipation vents on the side walls of the cabinet body. However, due to the principle that hot air rises and cold air falls, the hot air in the cabinet body is easily accumulated at the top of the cavity. It is difficult to exchange heat with the outside air only by relying on the ventilation and heat dissipation vents on the side walls of the cabinet body. Therefore, it is necessary to open a heat exhaust vent on the top of the distribution cabinet. Dust in the air is easily accumulated on the top of the distribution cabinet, and there is a lot of dust at the construction site. Therefore, when opening the heat exhaust vent on the top of the distribution cabinet body, a dust net should be added to prevent dust from falling into the cabinet body. However, dust will still accumulate on the dust net, and eventually it will affect the air circulation of the heat exhaust vent on the top of the distribution cabinet body, resulting in the cabinet body The heat exhaust effect is still not ideal, and humid air will increase the adhesion of dust on the dust net, which is difficult to clean, and thus there are defects.

[0003] An improved construction engineering power distribution cabinet with publication number CN220775170U includes a power distribution cabinet body, three ventilation air inlets are opened in parallel at the lower left end of the power distribution cabinet body, a filter is fixedly installed in each ventilation air inlet cavity, a first drying box is fixedly installed on one side wall of each filter, a heat exchange exhaust pipe is penetrated on the top surface of the power distribution cabinet body, a dustproof net is fixedly installed on the inner side wall of the heat exchange exhaust pipe, a shaft is rotatably connected at the axis of the dustproof net, a heat exchange fan blade is fixedly installed on the top of the shaft, and a second drying box is fixedly installed on the inner side wall of the lower end of the heat exchange exhaust pipe. The arrangement of the filter, the first drying box, the second drying box and the dustproof net effectively ensures the ventilation and heat exchange effect of the power distribution cabinet body, thereby effectively improving the protection effect of the electronic components in the power distribution cabinet body cavity.

[0004] The above-mentioned power distribution cabinet has a dustproof effect, but it is not convenient to quickly clean the dustproof net, and it cannot effectively prevent shock, so it needs to be improved. Summary of the invention
