[0014] The present invention provides a switch cabinet for multiple switchgears sharing a busbar chamber. It has the following beneficial effects: (1) This invention drives the fan to move up and down so that the generated airflow dissipates heat for the equipment, making the heat dissipation range wider and improving the heat dissipation effect. At the same time, the scraper moves downward to scrape off the dust attached to the filter plate, preventing the dust from adhering to the filter plate and affecting the heat dissipation effect of the equipment. The short rod moves toward the direction close to the L-shaped plate, which drives the free end of the elastic telescopic rod to contract. The contraction of the free end of the elastic telescopic rod drives the scraper to separate from the filter plate, preventing the scraper from scraping the filter plate for a long time, resulting in a reduction in the service life of the filter plate.

[0015] (2) In the present invention, the push rod moves downward to push the rotating plate to rotate downward. The downward rotation of the rotating plate causes the dust that falls on the rotating plate to fall into the collection box, preventing the scraped dust from floating back onto the filter plate, causing the dust on the filter plate to accumulate more and more, affecting the heat dissipation effect of the equipment. The collection box is divided into two layers by the rotating baffle plate, preventing the dust inside the collection box from floating out again when the rotating plate rotates downward, causing the dust to adhere to the filter plate, affecting the heat dissipation effect of the equipment. The reset of the pressure plate will be separated from the reset of the rotating baffle plate. The reset of the rotating baffle plate will cause the dust that falls on the rotating baffle plate to enter the collection box through the reset of the rotating baffle plate, thereby improving the dust collection effect.

[0016] (3) The invention pushes the sealing slide plate downward by rotating the baffle plate. The downward movement of the sealing slide plate will drive the water outlet to move downward. The downward movement of the water outlet will overlap with the connecting pipe. After the overlap, the water inside the water storage tank will be sprayed out through the connecting pipe. The sprayed water will suppress the dust that has fallen in, preventing the dust inside the collection box from floating out during the opening process, thereby affecting the dust suppression effect. The downward movement of the connecting rod will drive the sealing plate downward. The downward movement of the sealing plate will break away from the contact with the sealing ring, allowing the dust to be discharged together with the water through the drain groove, thereby preventing excessive accumulation of water inside and affecting the subsequent drainage effect.
