Description
Technical field
The utility model is related to a kind of exhausting windows.Specifically, it is mounted in having at box type transformer top vent
The exhausting window of noise elimination function.
Background technology
It is both known about in power industry, for ease of powering for residential building, box-type transformation is both provided near residential area
Device.When box type transformer is run, mechanical vibration noise and magnetic noise can be generated.This mechanical vibration noise and magnetic field are made an uproar meeting
As air-flow is discharged together from the exhaust outlet at the top of box type transformer, unfavorable shadow is brought to the health of surrounding resident and normal life
It rings.
Utility model content
Problem to be solved in the utility model is to provide a kind of box type transformer top vent window with noise elimination function.It adopts
With this exhausting window, the noise of box type transformer top vent discharge can be reduced, is avoided to the healthy and normal of surrounding resident
The adverse effect that life is brought.
The above problem to be solved in the utility model is realized by following technical scheme：
The box type transformer top vent window for having the characteristics that noise elimination function of the utility model is to include bottom cover, the bottom cover
Upward, cover on bottom has air admission hole to oral area, inside there is support tube.There is acoustic tube in support tube upper end, and the inside of acoustic tube is with respect to cylinder
There is sound absorbing baffle on wall.In the opposite both sides of sound absorbing baffle：One side thickness is more than another side, and thicker one side is connected to phase
It answers on the barrel of side, and cross-shaped positioned opposite between the featheredge of both sides sound absorbing baffle so that the wind between the sound absorbing baffle of both sides
Road is S-shaped.There is overhead guard above acoustic tube, the internal diameter of overhead guard is more than the outer diameter of acoustic tube, is borrowed between overhead guard oral area and acoustic tube upper end
Help stull to link together so that formed between overhead guard oral area and acoustic tube upper end surrounding between first as annular vent mouth
Away from.
Further improvement of the utility model scheme is that the upper and lower side of acoustic tube is connected with outlet baffle ring and import gear respectively
Circle is exported between baffle ring upper end and the cover bottom of overhead guard, is had respectively between the second spacing and third between import baffle ring lower end and bottom cover cover bottom
Away from.
Further improvement of the utility model scheme is that the bottom cover, acoustic tube, sound absorbing baffle and overhead guard are by absorbent treatment
It is formed with the steel plate for being connected to absorbent treatment two sides.
Further improvement of the utility model scheme is that absorbent treatment is block of glass wool.
The further improvement project of the utility model is that have annular filter screen in the first spacing.
Since the utility model contains bottom cover it can be seen from above scheme, upward, cover has on bottom the bottom cover oral area
Air admission hole inside has support tube.There is an acoustic tube in support tube upper end, and on barrel with respect to there is sound absorbing baffle in the inside of acoustic tube.It inhales
In the opposite both sides of sound baffle：One side thickness is more than another side, and thicker one side is connected on the barrel of corresponding side, and both sides
It is cross-shaped positioned opposite between the featheredge of sound absorbing baffle so that the air duct between the sound absorbing baffle of both sides is S-shaped.Have above acoustic tube
Overhead guard, the internal diameter of overhead guard are linked together by means of stull between overhead guard oral area and acoustic tube upper end, made greatly with the outer diameter of acoustic tube
It obtains and the first spacing as annular vent mouth is formed between overhead guard oral area and acoustic tube upper end surrounding.During work, by box type transformer
Top vent discharge air-flow by bottom cover cover bottom on air admission hole after, pass sequentially through import baffle ring, both sides sound absorbing baffle it
Between S-shaped air duct, outlet baffle ring, and flowed away after changing flow direction under the action of the overhead guard cover bottom to the surrounding at overhead guard cover bottom, finally,
It turns to downwards and is discharged after passing through the first spacing between overhead guard oral area and acoustic tube surrounding.Cause box type transformer top vent
Under the action of S-shaped air duct of the air-flow of discharge between import baffle ring, both sides sound absorbing baffle, outlet baffle ring and overhead guard, repeatedly change
Become flow direction, greatly reduce flow velocity so that noise has obtained primary attenuation.Again due to the bottom cover, acoustic tube, sound absorbing baffle and
Overhead guard is made of absorbent treatment with the steel plate for being connected to absorbent treatment two sides so that the air-flow of box type transformer top vent discharge
Receive secondary extinction.By the attenuation twice for the air-flow that box type transformer top vent is discharged, box change is greatly reduced
The noise of depressor top vent discharge, eliminates the adverse effect brought to the health of surrounding resident and normal life.
Description of the drawings
Fig. 1 is the box type transformer top vent window construction schematic diagram with noise elimination function of the utility model.
Specific embodiment
As shown in Figure 1, the box type transformer top vent window with noise elimination function of the utility model contains bottom cover 11, institute
It states bottom and covers 11 oral areas upward, covering processing on bottom, there are three air admission holes 13.Bottom, which is covered, is provided with support tube 1 in 11, on support tube 1
End is provided with acoustic tube 3, and the inside of acoustic tube 3 is with respect to being both provided with sound absorbing baffle 7 on barrel.The opposite both sides of sound absorbing baffle 7
In：One side thickness is more than another side, and thicker one side is connected on the barrel of corresponding side, and the featheredge of both sides sound absorbing baffle 7
Between it is cross-shaped positioned opposite so that the air duct between both sides sound absorbing baffle 7 is S-shaped.3 top of acoustic tube is provided with overhead guard 8, pushes up
The internal diameter of cover 8 is more than the outer diameter of acoustic tube 3, and 8 oral area of overhead guard and acoustic tube are linked together by means of stull 10 between 3 upper end, made
