Description
Technical field
The present invention relates to a kind of exhausting window.Specifically, having at box type transformer top vent is mounted in eliminate the noise
The exhausting window of function.
Background technology
Both known about in power industry, for ease of being powered 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 produced.This mechanical vibration noise and magnetic field are made an uproar meeting
As air-flow is discharged from the exhaust outlet at the top of box type transformer together, unfavorable shadow is brought to the health of surrounding resident and normal life
Ring.
The content of the invention
The problem to be solved in the present invention is to provide a kind of box type transformer top vent window with noise elimination function.Using this
Kind exhausting window, can reduce the noise of box type transformer top vent discharge, avoid the health to surrounding resident and normal life
The adverse effect brought.
The invention solves above mentioned problem realized by following technical scheme：
The box type transformer top vent window feature with noise elimination function of the present invention is to include bottom cover, the bottom cover oral area court
On, it, which is covered on bottom, air admission hole, has support tube in it.There is an acoustic tube support tube upper end, the inner side of acoustic tube with respect on barrel
There is sound absorbing baffle.In the relative both sides of sound absorbing baffle：One side thickness is more than another side, and its thicker one side is connected to corresponding side
On barrel, and it is cross-shaped positioned opposite between the featheredge of both sides sound absorbing baffle so that the air channel between the sound absorbing baffle of both sides is in S
Shape.There is overhead guard above acoustic tube, the internal diameter of overhead guard is more than the external diameter of acoustic tube, by means of horizontal stroke between overhead guard oral area and acoustic tube upper end
Support is linked together so that the first spacing as annular vent mouth is formed between overhead guard oral area and acoustic tube upper end surrounding.
Further improvement of the present invention scheme is that the upper and lower side of acoustic tube is connected with outlet back-up ring and import back-up ring respectively, goes out
There are the second spacing and the 3rd spacing respectively between mouth back-up ring upper end and the cover bottom of overhead guard, between import back-up ring lower end and bottom cover cover bottom.
Further improvement of the present invention scheme is that bottom cover, acoustic tube, sound absorbing baffle and the overhead guard are by absorbent treatment and company
The steel plate for being connected on absorbent treatment two sides is formed.
Further improvement of the present invention scheme is that absorbent treatment is block of glass wool.
The further improvement project of the present invention is that have annular filter screen in the first spacing.
Because the present invention is containing bottom cover it can be seen from above scheme, upward, it is covered on bottom air inlet to the bottom cover oral area
Hole, there is support tube in it.There is an acoustic tube support tube upper end, and on barrel with respect to there is sound absorbing baffle the inner side of acoustic tube.Sound absorbing
In the relative both sides of plate：One side thickness is more than another side, and its thicker one side is connected on the barrel of corresponding side, and both sides absorb sound
It is cross-shaped positioned opposite between the featheredge of baffle plate so that the air channel between the sound absorbing baffle of both sides is S-shaped.There is top above acoustic tube
Cover, the external diameter of the internal diameter of overhead guard greatly with acoustic tube, is linked together between overhead guard oral area and acoustic tube upper end by means of stull so that
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
The air-flow of portion's exhaust outlet discharge is passed sequentially through between import back-up ring, both sides sound absorbing baffle after the air admission hole that bottom is covered on cover bottom
S-shaped air channel, outlet back-up ring, and flowed away after changing flow direction in the presence of the overhead guard cover bottom to the surrounding at overhead guard cover bottom, finally, to
It is lower to turn to and discharged after passing through the first spacing between overhead guard oral area and acoustic tube surrounding.So that box type transformer top vent is arranged
In the presence of S-shaped air channel of the air-flow gone out between import back-up ring, both sides sound absorbing baffle, outlet back-up ring and overhead guard, it is varied multiple times
Flow direction, greatly reduces flow velocity so that noise has obtained once decaying.Again due to bottom cover, acoustic tube, sound absorbing baffle and the top
Cover by absorbent treatment and be connected to absorbent treatment two sides steel plate form so that box type transformer top vent discharge air-flow by
Secondary extinction is arrived.The decay twice for the air-flow discharged by box type transformer top vent, greatly reduces box-type transformation
The noise of device top vent discharge, eliminates the adverse effect brought to the health of surrounding resident and normal life.
Brief description of the drawings
Fig. 1 is the box type transformer top vent window construction schematic diagram with noise elimination function of the present invention.
Embodiment
As shown in figure 1, the box type transformer top vent window with noise elimination function of the present invention contains bottom cover 11, the bottom
Cover 11 oral areas upward, it covers is machined with three air admission holes 13 on bottom.Support tube 1 is provided with bottom cover 11, the upper end of support tube 1 is set
It is equipped with acoustic tube 3, the inner side of acoustic tube 3 is with respect to being provided with sound absorbing baffle 7 on barrel.In the relative both sides of sound absorbing baffle 7：One
Side thickness is more than another side, and its thicker one side is connected on the barrel of corresponding side, and is submitted between the featheredge of both sides sound absorbing baffle 7
It is forked positioned opposite so that the air channel between both sides sound absorbing baffle 7 is S-shaped.The top of acoustic tube 3 is provided with overhead guard 8, overhead guard 8
Internal diameter is more than the external diameter of acoustic tube 3, is linked together between the oral area of overhead guard 8 and the upper end of acoustic tube 3 by means of stull 10 so that overhead guard
The first spacing 4 as annular vent mouth is formed between 8 oral areas and the upper end surrounding of acoustic tube 3.Ring is installed in first spacing 4
Shape filter screen 9.
Outlet back-up ring 5 and import back-up ring 2, the outlet upper end of back-up ring 5 and overhead guard 8 are connected with respectively in the upper and lower side of acoustic tube 3
Cover bottom between, the lower end of import back-up ring 2 and bottom cover 11 cover bottom between be respectively kept with the second spacing 6 and the 3rd spacing 12.
To improve noise elimination function, bottom cover 11, acoustic tube 3, sound absorbing baffle 7 and the overhead guard 8 by absorbent treatment and are connected to
The steel plate on absorbent treatment two sides is formed.Absorbent treatment therein is block of glass wool.
During work, by the air-flow that box type transformer top vent is discharged after the air admission hole 13 on the cover bottom of bottom cover 11,
Pass sequentially through the S-shaped air channel between import back-up ring 2, both sides sound absorbing baffle 7, export back-up ring 5, and in the presence of overhead guard 8 covers bottom
