A distribution box for a machine room

Abstract

The invention discloses a power distribution box for a computer room, relates to the technical field of power distribution boxes, and mainly aims to solve the problem that the existing power distribution box for a computer room cannot effectively clean the dust on the dustproof net, including the power distribution box, Dust-proof assembly and cleaning mechanism, the dust-proof assembly is provided with a dust-proof net, and the cleaning mechanism includes a dust-cleaning assembly and a gas circulation assembly. The circulation assembly includes a gas circulation part and a filter and dust removal part that are connected to each other. The gas generated in the gas circulation part is blown to the dust filter through the exhaust holes on the auxiliary dust removal part, and the dust adhering to the dust filter can be blown to the main filter. The dust scraper on the main dust removal part can scrape off the dust adhering to the surface of the dust filter, and the dust suction hole can suck the dust into the filter dust removal part. It enters the gas circulation part for recycling, and has the characteristics of good dust removal effect.

Description

technical field [0001] The invention relates to the technical field of distribution boxes, in particular to a distribution box for a machine room. Background technique [0002] The computer room is generally equipped with a distribution box. The distribution box is a low-voltage distribution box that assembles switchgear, measuring instruments, protective appliances and auxiliary equipment in a closed or semi-closed metal cabinet or on a screen according to the requirements of electrical wiring. During normal operation, the circuit can be connected or disconnected by manual or automatic switch, and the circuit can be cut off or alarmed by means of protective electrical appliances in case of failure or abnormal operation. Various parameters in operation can be displayed by means of measuring instruments, and some electrical parameters can also be adjusted. , to prompt or signal the deviation from the normal working state. [0003] However, the casing of the existing power di...

Problems solved by technology

[0003] However, the casing of the existing power distribution box in the computer room is equipped with a grille or a dust-proof net. On the one hand, it is used to prevent dust, and on the other hand, it is used for ventilation and heat dissipation. For some dust with small particles, although the dust-proof net can block these dusts, the long-term adhesion of these dusts to the dust-proof net will cause the dust-proof net to be blocked, making it lose the function of ventilation and heat dissipation, which is also used in some existing patents The solution of cleaning the brush to automatically clean these dusts, but these solutions will have some disadvantages:

[0004] 1. The dust cleaned from the dust-proof net will fall into the distribution box again, causing the dust to adhere to the electronic components inside, shortening the service life of the electronic components;

[0005] 2. The dust-proof net is generally fixed, and it needs to be driven by the driving device to move the cleaning brush repeatedly to achieve cleaning, and the dust generally adheres to the inner or outer surface of the dust-proof net, and the cleaning brush cannot clean the dust inside. It is time-consuming and laborious to clean up, and it is not easy to clean
