Description

Technical Field

[0002] Power quality modules are widely used in residential buildings, office buildings, industrial and mining enterprises, etc. Power quality modules are usually installed in a metal box, and in order to ensure the heat dissipation effect of the power quality module, heat dissipation holes are provided on the outside of the box.

[0003] According to the application number "202320174423.X", the dust in the air is filtered through the dust filter plate to avoid dust accumulation on the power quality module. The dust filter plate is cleaned up and down by a roller brush to avoid dust adhering to the dust filter plate, causing the filter holes of the dust filter plate to be blocked and affecting normal heat dissipation. Moreover, it is convenient to collect and discharge the cleaned dust out of the box.

[0004] In the process of implementing the solution, the inventors found that the following problems existed in the prior art and were not well solved:

[0005] There are many structures, which take up a large space inside the box;

[0006] Although it has the functions of internal dust cleaning and dust exhaust, it needs to be equipped with a driving device, which increases energy consumption. When cleaning dust, although the dust can be discharged out of the box by exhausting air, the wind force is limited and the dust cannot be completely sucked out. Instead, dust splashes inside the box when the roller rolls and brushes the dust.

[0007] It can only process the dust in the circulating air. If it is humid and rainy, it cannot process the humid gas. Utility Model Content
