Abstract
The utility model discloses a silencing and sound-insulating integrated device, which comprises double composite sound-absorbing walls, a shutter, an air vent and a sound-insulating door. The double composite sound-absorbing walls are laid on the wall of the integrated device, the upper part of one composite sound-absorbing wall is provided with the shutter, the middle part of the composite sound-absorbing wall is provided with the sound-insulating door, and the bottom of the composite sound-absorbing wall is provided with the air vent. The device is attractive and has a scientific and reasonable structural layout and high sound-absorbing performance, and the effects of ventilation and environmental protection can be achieved while the sound-absorbing effect is realized.
Description
Technical field
The utility model belongs to the environmental protection field, is specifically related to a kind of noise elimination sound insulation integration unit.
Background technology
The city is the developed area; It also is the population concentration area; The construction of transformer station is when solving the urban electric power demand; Brought new environmental problem again, a large amount of transformers is installed in the resident area of concentration, and its running noises has seriously disturbed people's normal life, work, study and rest.For slowing down the influence of transformer noise near resident, present city transformer station all is placed on transformer indoor, and indoor transformer station is helped in design.Basically can control the running noises of wattage transformer through house sound insulation and shielding; But the noise of high-power transformer still has influence on outdoor environment; Particularly electric pressure, often adds blower fan, the window of leaving a door unlocked, punches because of ventilation and heat needs greater than the indoor transformer station of 35kV on the wall of transformer station's building, makes indoor noise pass through door, window, ventilation hole oral instructions to outdoor; Also have minority transformer station incorrect because of design, installation; It is outdoor that the vibration of transformer is reached through building, even reach in the adjacent esidential building, produces the secondary noise radiation and pollute.Transformer station when electric energy being provided for the townsfolk also near the resident brought worry.
Summary of the invention
Goal of the invention: the purpose of the utility model is the deficiency to prior art, and one group of noise elimination sound insulation integration unit is provided.
Technical scheme: in order to achieve the above object; The utility model is specifically realized like this: a kind of noise elimination sound insulation integration unit; Comprise two-layer compound acoustic wall, shutter, ventilation opening and soundproof door, be equipped with the two-layer compound acoustic wall on the integration unit wall, wherein a sidewalls top is provided with shutter; The middle part is provided with soundproof door, and the bottom is provided with ventilation opening.
Wherein, said soundproof door internal layer be galvanized sheet or Coil Coating Products, middle for the cotton outsourcing glass of compound noise elimination cloth, outerly be the panel of warship with sheet material matter.
Wherein, said noise elimination shutter is connected with one group of noise elimination plenum chamber, is provided with blower fan between the noise elimination plenum chamber.
Be connected with fire resisting damper and soft the connecing of fire prevention between above-mentioned noise elimination plenum chamber and blower fan, also can do suitable ordering adjustment according to technological requirement.
Beneficial effect: compare with conventional art, the utlity model has following advantage:
(1) sound-absorbing wallboard good looking appearance, the spectral characteristics of noise during according to substation transformer and fan operation adopts the helmholtz resonance structure, has reduced noise pollution effectively;
(2) shutter appearance looks elegant has rainproof and good sound absorbing capabilities;
(3) sound insulation noise reduction door is handsome in appearance, multiple noise reduction measure, and sound insulation erasure effect is remarkable, and the noise elimination shutter can satisfy air-conditioning requirement simultaneously in the door of increase;
(4) transformer chamber's ventilated synthetic device adopts the box centrifugal blower of low noise, has reduced noise through noise elimination plenum chamber and sound absorber better with the noise elimination shutter, and subsidiary attemperating unit had both solved transformer chamber's ventilation, lower the temperature requirement, energy-conserving and environment-protective again.
