In the opposite both sides of sound absorbing baffle：Its one side is thicker than another side, its webbing is connected on the barrel of corresponding side, and both sides sound absorbing
It is cross-shaped positioned opposite between the featheredge of plate so that the air passage between the sound absorbing baffle of both sides is S-shaped.There is overhead guard above acoustic tube,
The internal diameter of overhead guard is more than the outside diameter of acoustic tube, is linked together between overhead guard oral area and acoustic tube upper end by means of stull so that top
The first spacing as annular vent mouth is formed between cover 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 baffle ring and import baffle ring respectively, goes out
There is the second spacing between mouth baffle ring upper end and the cover bottom of overhead guard, between the cover bottom that import baffle ring lower end and bottom are covered.
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.
Since the present invention is containing including base it can be seen from above scheme, there is shell on base, have on front side of shell every
Glottis, has the first hole on soundproof door, has inlet box in the first hole；Second hole is arranged at the rear wall top of shell, has air draft in the second hole
Machine, has kuppe outside exhaust blower；The upper wall and two side walls of the kuppe are connected with the rear wall of shell, kuppe
There is exhaust outlet under cover between side and rear wall；The shell and kuppe it is compound by the outer layer of absorbent treatment and absorbent treatment two sides and
Into；The absorbent treatment is block of glass wool, and outer layer is steel plate.There is venthole in sheath top plate, there is exhausting window, exhausting window on top plate
The air inlet of bottom is connected with the venthole on top plate.During work, outside air enters shell by the inlet box on soundproof door,
To in shell charging station cooling after be divided into two-way, all the way by exhaust blower and kuppe after, have under cover between side and rear wall
Exhaust outlet is discharged.Another way passes through the S between the venthole on top plate, the air admission hole on fumer cover bottom, both sides sound absorbing baffle
After spacing between the cover bottom in shape air passage, outlet baffle ring upper end and overhead guard, formed between overhead guard oral area and acoustic tube upper end surrounding
Annular vent mouth is discharged.So that noise caused by charging station work is blocked under the action of the sound absorbing baffle road of both sides, make to make an uproar
Sound is collided and decayed in communication process.Again since the shell, kuppe, inlet box and fumer are by absorbent treatment
Be combined with the outer layer on absorbent treatment two sides, when air-flow by when, a part of noise is isolated, and another part noise is absorbed,
Decay again so that being received with noisy air-flow.By decaying twice, greatly reduce caused by charging station operation
Noise, eliminate the health and the adverse effect brought of normal life to surrounding resident.
