Description

Amortization cover with inhale sound structure

Technical Field

The utility model relates to the technical field of sound attenuation and sound insulation, in particular to a sound attenuation cover with a sound absorption structure.

Background

With the development of modern industry, environmental pollution is generated, and noise pollution is one kind of environmental pollution and is a great harm to human beings. Noise is the sound that a generator makes when it is random. Sound is caused by vibration of an object and propagates in a certain medium (such as solid, liquid, gas) in the form of waves. The sound that is typically heard is airborne sound. Therefore, from the viewpoint of environmental protection, all sounds disturbing people's rest, study and work, i.e., unwanted sounds, are collectively called noise. Noise pollution is created when noise adversely affects people and the surrounding environment.

Noise treatment can be from several aspects of sound source, propagation route, noise protection, in industrial production process, the noise that some machinery sent is difficult to thoroughly eliminate the noise through the sound source, however adopt noise protection, let the workman take appliances such as earphone, earplug, earmuff, bring inconvenience for the workman, the noise makes workman's mood restless, seriously influences workman work efficiency, increases unnecessary manufacturing cost, according to above-mentioned circumstances, imagine eliminating noise reduction from the propagation route. Therefore, we propose a muffling enclosure with a sound-absorbing structure.

SUMMERY OF THE UTILITY MODEL

The present invention is directed to a noise reduction cover with a sound absorption structure to solve the above problems.

In order to achieve the purpose, the utility model provides the following technical scheme:

the design one kind has the amortization cover of the sound-absorbing structure, including the amortization cover, its characterized in that: the inner container is connected to the inner wall of the silencing cover, a first mounting cavity is arranged between the inner container and the silencing cover, a first silencing plate is arranged in the first mounting cavity in a corrugated mode, the first silencing plate separates the first mounting cavity into gaps, first silencing cotton is arranged in each gap, and first silencing holes penetrate through the inner container.

The first silencing plate is internally provided with a second mounting cavity, a second silencing plate is mounted in the second mounting cavity, second silencing holes are formed in the second silencing plate, and second silencing cotton is connected in the second mounting cavity between the second silencing plates.

Preferably, one side of the silencing cover is connected with a sealing door through a hinge, a handle is mounted on the side wall of the sealing door, and a rubber sealing strip is sealed between the sealing door and the silencing cover.

Preferably, a cotton felt is arranged on the inner wall of the inner container.

Preferably, the first silencing cotton and the second silencing cotton are rock wool silencing cotton.

Compared with the prior art, the utility model has the beneficial effects that: according to the silencing cover with the sound absorption structure, the first silencing hole and the cotton felt are arranged, so that noise emitted by machinery can be simply silenced by entering the silencing cover, and the effect of reducing the noise in the first step is achieved; the second silencing plate, the second silencing hole, the second mounting cavity and the second silencing cotton are arranged, so that noise can enter the second silencing plate, the noise is disturbed in the second silencing hole, and the second silencing cotton absorbs the noise, and the second effect of efficiently reducing the noise is achieved; by arranging the first silencing plate and the first silencing cotton, noise can enter the first silencing plate and is disordered again on the first silencing plate, and then the first silencing cotton absorbs the noise again, so that the effect of reducing and eliminating the noise in the third step is achieved; through setting up a door, a handle, can will seal a door through the handle and open, put into noise reduction cover with the great machinery of noise inside, reach the effect of being convenient for place parcel noise machinery for this has noise reduction cover of inhaling sound structure, simple structure breaks the noise abatement from the propagation path of noise, and noise cancelling effect is showing, absorbs the noise pollution isolation at the mechanical production scene, has reduced the noise and has promoted production efficiency to workman work efficiency's influence.
