Description
Technical field
The present invention relates to a kind of static press devices.Specifically, it is mounted in the exhaust outlet of main transformer of transformer substation room, is used for pair
Substation exhaust outlet carry out static pressure, sound absorption static pressure mechanism.
Background technology
It is fitted with shutter in power industry, main transformer of transformer substation room exhaust outlet at present, to match with air inlet
The gravity-flow ventilation heat dissipation for covering to realize main transformer room.Since shutter only has ventilation and heat function, do not insulate against sound sound absorption function,
So that the noise generated in main transformer operational process can outward be disseminated by shutter, be unfavorable for surrounding resident health and
Normal life.
Invention content
The problem to be solved in the present invention is to provide a kind of substation's exhaust outlet static pressure mechanism.This static pressure mechanism, it is existing
Ventilation and heat function, and have sound insulation sound absorption function.Using this static pressure mechanism, be conducive to the healthy and normal life of surrounding resident
It is living.
The invention solves the above problem realized by following technical scheme：
The present invention substation's exhaust outlet be with static pressure mechanism feature include noise absorption cover, there is gas outlet at the cover bottom center of noise absorption cover.
There is the sound absorption U-lag that cover mouth is divided into two air inlets at the cover mouth of noise absorption cover, the notch for the U-lag that absorbs sound is outwardly.Absorb sound U-lag
Slot bottom outside there is valve plate, valve plate to be hinged among slot bottom on one side, and valve plate can be rotated around its hinge joint to two air inlet sides.
There is deflector in inlet channel corresponding with air inlet.Deflector one side, deflector and gas outlet opposite with corresponding air inlet
Adjacent is connected on one side on the inside of gas outlet, and the cover wall for being connected to corresponding air inlet side on one side not adjacent to gas outlet is vertical
To middle.
Among width between the hinge side of the valve plate and its opposite side is more than outside slot bottom and deflector is adjacent to gas outlet
Spacing between one side.
Further improvement of the present invention scheme is that the noise absorption cover contains outer layer, middle layer and internal layer, and the outer layer is steel
Plate, the internal layer are the steel plates for being evenly equipped with punching, and the middle layer is block of glass wool.
Further improvement of the present invention scheme is that the sound absorption U-lag contains outer layer, middle layer and internal layer, the outer layer
It is steel plate, the internal layer is the steel plate for being evenly equipped with punching, and the middle layer is block of glass wool.
The further improvement project of the present invention is that the noise absorption cover is cuboid, longitudinal direction and the outer cover length side of U-lag
To parallel, U-lag both ends link together with two cover walls of cover mouth respectively.
Since the present invention contains noise absorption cover it can be seen from above scheme, there is gas outlet at the cover bottom center of noise absorption cover.Sound absorption
There is the sound absorption U-lag that cover mouth is divided into two air inlets at the cover mouth of cover, the notch for the U-lag that absorbs sound is outwardly.The slot of sound absorption U-lag
There are valve plate, valve plate to be hinged among slot bottom on one side outside bottom, and valve plate can be rotated around its hinge joint to two air inlet sides.With into
There is deflector in the corresponding inlet channel of gas port.Deflector one side is opposite with corresponding air inlet, and deflector is adjacent with gas outlet
Be connected on one side on the inside of gas outlet, not adjacent to gas outlet is connected on one side in the cover wall longitudinal direction of corresponding air inlet side
Between.When work, an inlet close in two air inlets is as spare.In main transformer voltage device operational process, main transformer
The indoor air-flow of depressor flows to valve plate after another air inlet enters outer cover under the action of deflector.Then, in valve plate
Gas outlet is flowed under effect.Since noise absorption cover and sound absorption U-lag contain outer layer, middle layer and internal layer, the outer layer is steel plate,
The internal layer is the steel plate for being evenly equipped with punching, and the middle layer is block of glass wool.It makes a slip of the tongue so that air-flow flows to outlet from air inlet
The noise generated by air-flow in journey is absorbed by noise absorption cover and sound absorption U-lag, exhaust outlet when to eliminate main transformer operation
Noise.Therefore, the existing ventilation and heat function of the present invention, and have sound insulation sound absorption function.Using this static pressure mechanism, be conducive to week
Enclose health and the normal life of resident.
