Description
Technical field
The utility model is related to a kind of inlet boxs.Specifically, it is mounted in the air inlet of main transformer of transformer substation room, with arranging
The mating compound inlet box for main transformer room gravity-flow ventilation heat dissipation of gas port.
Background technology
Be fitted with shutter in power industry, transformer and distribution power station main transformer room air inlet at present, so as to exhaust outlet
It is mating come realize the gravity-flow ventilation of main transformer room radiate.Since shutter only has ventilation and heat function, do not insulate against sound sound absorption work(
It can so that the noise generated in main transformer operational process can outward be disseminated by shutter, be unfavorable for the strong of surrounding resident
Health and normal life.
Utility model content
Problem to be solved in the utility model is to provide a kind of compound inlet box.This compound inlet box is existing logical
Wind heat sinking function, and have sound insulation sound absorption function.Using this compound inlet box, be conducive to the healthy and normal life of surrounding resident
It is living.
The above problem to be solved in the utility model is realized by following technical scheme：
The compound inlet box feature of the utility model is to include sound absorption block, have on the sound absorption block be mutually parallel it is flat
There are outer cover and inner cover in hole, outside and the inside respectively.The vertical edge of the outer cover oral area and top with the corresponding edge phase of sound absorption block
Even, the following of outer cover oral area has the air inlet entered convenient for natural wind between sound absorption block.The quadrangle of the inner cover oral area by
Short tube is connected with the quadrangle of sound absorption block so that there are the spacing as exhaust outlet between inner cover oral area and sound absorption block surrounding.In inner cover
There is gas collection baffle liner, gas collection baffle liner one end is connected with sound absorption block, and the flat hole is respectively positioned in gas collection baffle liner.
Further improvement of the utility model scheme is, is had deflector in sound absorption block one side that outer cover covers.It is described to lead
The top of flowing plate is connected on the sound absorption block between that nethermost flat hole and air inlet, and the following of deflector tilts in upward
Shape is arranged.
Wherein, the sound absorption block block of glass wool and be made.
Further improvement of the utility model scheme is that the inner cover and outer cover are containing face layer and internal layer, the face layer
It is steel plate, the internal layer is the block of glass wool for being evenly equipped with punching.
Further improvement of the utility model scheme is that the flat hole is lateral aperture.
Further improvement of the utility model scheme is that the flat hole is vertical core.
Further improvement of the utility model scheme is that the air inlet is formed by removing the lower cover wall of outer cover.
The further improvement project of the utility model is that have protection network in air inlet.
Since the compound inlet box of the utility model contains sound absorption block.The flat hole being mutually parallel is machined on sound absorption block,
Its outside and the inside are respectively arranged with outer cover and inner cover.The vertical edge of outer cover oral area and top are connected with the corresponding edge of sound absorption block,
The following of outer cover oral area has the air inlet entered convenient for natural wind between sound absorption block.The quadrangle of the inner cover oral area point is by short
Pipe is connected with the quadrangle of sound absorption block so that there are spacing between inner cover oral area and sound absorption block.There is gas collection baffle liner in inner cover, collect conductance
Liu Quan one end is connected with sound absorption block, and the flat hole is respectively positioned in gas collection baffle liner.During work, external natural wind from air inlet into
After entering outer cover, after flat hole and the baffle ring on sound absorption block are sequentially passed through under the action of deflector, enter from the surrounding of baffle ring outer end
In inner cover.Then, under the blocking of inner cover, flow to inner cover surrounding, and from the spacing of inner cover and the surrounding of sound absorption block discharge and into
Enter in main transformer room.So as to fulfill the ventilation and heat to main transformer room.Again due to used in the sound absorption block, outer cover and inner cover
Material is all block of glass wool, has sound insulation and sound absorption function, can reduce noise caused by the natural wind flowed through.Cause this practicality
It is novel that not only there is ventilation and heat, also have the function of to reduce noise, function is more complete.Again due to having the function of to reduce noise,
The noise generated in main transformer operational process can be reduced to disseminate outward by shutter, be conducive to surrounding resident health and
Normal life.
