Dustproof heat dissipation power distribution cabinet device suitable for construction site

Abstract

The invention relates to the related field of power distribution cabinets, and discloses a dustproof heat dissipation power distribution cabinet device suitable for a construction site, which comprises a main body box, a power distribution cavity is arranged in the main body box, and the left end of the power distribution cavity is communicated with a fan cavity; the left end wall of the fan cavity is communicated with a dust filter cavity with an opening to the left, a filter box is matched with a monitoring spring to monitor the blockage condition of a dust filter screen in real time, so that when the dust is blocked to a certain degree, a friction roller is triggered to rotate to drive the dust filter screen to transmit downwards, and the position of the filter part of the dust filter screen is exchanged; therefore, the dust filter screen on one side is blocked to transmit downwards, and the filter screen on the unblocked part continues to work, so that normal heat dissipation in the power distribution cabinet body is ensured, dust transmitted downwards along with the dust filter screen can be removed and collected through the dust removal piston, automatic cleaning of the dustfilter screen is realized, and the dust filter screen can continuously work.

Description

technical field [0001] The invention relates to the related field of power distribution cabinets, in particular to a dust-proof heat dissipation power distribution cabinet device suitable for construction sites. Background technique [0002] Due to the reason of open-air placement, most of the power distribution cabinets currently used on construction sites are equipped with cooling fans to dissipate heat from the circuits in the power distribution cabinets and ensure the safety of the lines. In order to prevent the entry of dust from affecting the safety of the circuit, a dust filter is generally installed at the vent where the cooling fan is located. Reduce the heat dissipation effect of the power distribution cabinet, and even the cabinet will cause certain electricity accidents due to high temperature, and because there is a lot of dust on the construction site, frequent cleaning or replacement of the filter screen is also more troublesome.
