A self-dusting power cabinet with a resistant sound-absorbing structure

Abstract

The invention discloses a self-dusting power cabinet with a resistant and noise-absorbing structure, comprising: a power cabinet body, an air inlet is opened at the bottom of one side of the power cabinet body, and an air outlet is opened at the upper rear side of the power cabinet body. A resistance muffler is installed horizontally on the upper part of the power cabinet body. One end of the resistance muffler is sealed and connected to the air outlet through a wind cover, and the other end of the resistance muffler is sealed and connected to the speed-regulating fan through a rubber hose. The inner wall of the air inlet is installed and fixed on the The dust-absorbing bellows at the lower part of the profile skeleton, the dust-absorbing bellows are installed with a dust-absorbing roller through the rotation of the rotating shaft; the unified planning and design of noise reduction, heat dissipation, and dust removal are realized through the cooperation of the resistant muffler and the speed-regulating fan Using it can not only effectively adjust the heat dissipation state in the power cabinet, but also reduce the noise coming out of the power cabinet. The dust removal process is carried out from the source through the dust suction bellows to avoid the trouble of cleaning after dust enters the power cabinet.

Description

technical field [0001] The invention relates to the technical field of power equipment, in particular to a self-dusting power cabinet with a resistant noise reduction structure. Background technique [0002] The power cabinet is a power facility for distributing power. The power cabinet is widely used, mainly used in the chemical industry, environmental protection industry, power system, metallurgical system, industry, nuclear power industry, fire safety monitoring, transportation industry, etc., when the power equipment is running A large amount of heat will be generated, and the heat needs to be discharged from the cabinet in time, otherwise the heat will accumulate, which will easily cause the aging of the power equipment and easily affect the normal operation of the electrical components inside the power cabinet. During the heat dissipation process of the power cabinet, external dust will enter the interior of the power cabinet through the heat dissipation holes and adhe...

AI Technical Summary

Problems solved by technology

[0004] In the prior art, the noise reduction and dust removal of power cabinets has the following deficiencies: 1. Noise reduction, heat dissipation, and dust removal are often separated. In fact, the main component that emits noise in the power cabinet is the cooling fan. The passive cooling and active cooling effects are the same as The noise of the fan is positively correlated, and the accumulation of dust and dust will have a negative impact on the heat dissipation of the power cabinet. These three are interrelated; 2. The cooling fan and the air outlet are the main noise sources. Part of the focus is on noise reduction. Dust enters the power cabinet mainly through the air inlet. Ordinary brushes or filters cannot block dust quickly and efficiently.
