Blower fan is generally arranged in transformer room, is to be then communicated with inside and outside transformer room by the mode of punchinging in transformer room, and blower fan sucks outdoor cool air, then blows to converting equipment and lowers the temperature; In running, can produce noise, these noises propagate into outside transformer room by the vent hole of transformer room, and because indoor substation operated by rotary motion is in residential belt, thereby the noise that blower fan produces has a strong impact near the resident's in transformer room life, although current each electric substation all adopts noise reducing apparatus to reduce noise, such as the vent hole installation venetian blind in transformer room reduces noise, but these existing noise reducing apparatus can only be by few a part of reducing noise, and most of noise still impacts resident; And blower fan can produce vibrations noise in operation process, converting equipment can produce noise in the course of the work equally, the noise that the blade rotary of these noises and blower fan produces, the noise stack of operation vibrations noise and converting equipment, intake grill (blower fan is generally arranged on the wall of transformer room, chisels hole and form intake grill for fan air intake on wall) by blower fan makes the overall noise of electric substation propagate still far.
Therefore, a kind of equipment for electric substation's assembling need to be proposed, the noise that blower fan and converting equipment can be produced intercepts and absorbs, effectively avoid above-mentioned noise from being diffused in transformer room outdoor and affecting the life of surrounding resident, and can effectively reduce the vibrations noise that blower fan produces in running, simple in structure, easily manufactured.
Model utility content
In view of this, the purpose of this utility model is to provide a kind of noise-reducing type assembling assembly for electric substation, the noise that blower fan and converting equipment can be produced intercepts and absorbs, effectively avoid above-mentioned noise from being diffused in transformer room outdoor and affecting the life of surrounding resident, and can effectively reduce the vibrations noise that blower fan produces in running, simple in structure, easily manufactured.
The noise-reducing type assembling assembly for electric substation that the utility model provides, comprises the mounting cylinder for fixedly mounting blower fan, and the air intake of described mounting cylinder is fixedly installed noise reduction cylinder.
Further, described noise reduction cylinder is cone structure, and the flared end of described noise reduction cylinder is communicated with mounting cylinder sealing, and the bottom of described noise reduction cylinder is provided with intake grill, and the slot end end sidewalls of described noise reduction cylinder is provided with intake opening.
Further, the madial wall of described noise reduction cylinder is corrugated surface structure.
Further, described noise reduction cylinder madial wall is also provided with and the conformal absorbent treatment coordinating of described noise reduction cylinder madial wall.
Further, the flared end of described noise reduction cylinder is communicated with the air intake sealing of described mounting cylinder by a bellows.
Further, the cross section of described mounting cylinder is square structure, and a described mounting cylinder wherein sidewall is provided with the elastic cushion block for supporting blower fan.
Further, the relative two side of described mounting cylinder is fixedly installed and is useful on the elastic component that blower fan is fixed, and this relative two side is adjacent with the sidewall that is provided with elastic cushion block.
Further, described elastic component is spring.
The beneficial effects of the utility model: the utility model is by the noise reduction cylinder of cone structure, can make noise that blower fan and converting equipment produce in noise reduction cylinder through multiple reflections and be absorbed, can effectively avoid above-mentioned noise to affect the life of surrounding resident from being diffused in transformer room outdoor; By beam and elastic component, the vibrations noise that can effectively avoid blower fan to produce in running, carries out noise reduction from the source of generation of noise, and then strengthens anti-acoustic capability of the present utility model; Simple in structure, easily manufactured.
Accompanying drawing explanation
