Abstract
The present invention relates to the noise abatement casing structure of a kind of machine room, including machine room cover body, machine room cover body is provided with noise source, one upper lateral part of described machine room cover body is provided with noise reduction air intake duct, the bottom of opposite side is provided with noise reduction air-out groove, and the inner end of described noise reduction air-out groove is provided with trumpet-shaped guide duct；The inside top of machine room cover body is provided with the arc deflector that internal and external partition is arranged, and arc deflector is provided with pod apertures；Described arc deflector includes three layers, and the inner side of the arc deflector being positioned at outer layer and intermediate layer is provided with sponge noise reduction layer.The present invention uses the arc deflector structure that Spaced is arranged, and sound wave constantly reflects in the pod apertures of deflector, and acoustic energy is constantly consumed, and sets up sponge and carries out sound-absorbing, it is achieved flat noise reduction, which effectively reduces the noise of machine room.
Description
Technical field
The present invention relates to environmental technology field, particularly to the preventing and treating equipment of noise.
Background technology
Along with national economy and industrial fast development, and the raising day by day of environmental requirement, noise pollution and atmospheric pollution,
Water pollution has become three big Environmental Pollutions in the range of the world today, people's physical and mental health is caused strong influence, therefore
It effectively must be administered.Noise abatement utilizes various sound insulation, sound-absorbing material and silencing equipment to carry out noise source exactly
Block, intercept, to reduce the purpose of sound pollution.Current also do not have a kind of effective noise abatement device in machine room,
All kinds of small-sized muffling devices or this Sound-proof material is generally used to reduce noise, but all good effects of neither one.
Summary of the invention
The applicant, for the disadvantages mentioned above of prior art, studies and improves, it is provided that the noise abatement case knot of a kind of machine room
Structure, it significantly reduces machine room noise, has simple in construction, feature reasonable in design.
In order to solve the problems referred to above, the present invention uses following scheme:
The noise abatement casing structure of a kind of machine room, including machine room cover body, is provided with noise source, described machine room cover in machine room cover body
One upper lateral part of body is provided with noise reduction air intake duct, and the bottom of opposite side is provided with noise reduction air-out groove, the inner of described noise reduction air-out groove
Portion is provided with trumpet-shaped guide duct；The inside top of machine room cover body is provided with the arc deflector that internal and external partition is arranged, and arc is led
It is provided with pod apertures on stream plate；Described arc deflector includes three layers, is positioned at the inner side peace of the arc deflector in outer layer and intermediate layer
Equipped with sponge noise reduction layer.
The method have technical effect that:
The present invention uses the arc deflector structure that Spaced is arranged, and sound wave constantly reflects in the pod apertures of deflector, acoustic energy
Constantly it is consumed, sets up sponge and carry out sound-absorbing, it is achieved flat noise reduction, which effectively reduces the noise of machine room.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
In figure: 1, machine room cover body；2, noise reduction air intake duct；3, noise reduction air-out groove；4, guide duct；5, arc deflector；51、
Pod apertures；6, noise source；7, noise reduction spongy layer.
Detailed description of the invention
Below in conjunction with the accompanying drawings the detailed description of the invention of the present invention is described further.
As it is shown in figure 1, the noise abatement casing structure of the machine room of the present embodiment, including machine room cover body 1, machine room cover body 1 is pacified
Equipped with noise source 6, a upper lateral part of machine room cover body 1 is provided with noise reduction air intake duct 2, and the bottom of opposite side is provided with noise reduction air-out groove
3, the inner end of noise reduction air-out groove 3 is provided with trumpet-shaped guide duct 4；The inside top of machine room cover body 1 is provided with internal and external partition
The arc deflector 5 arranged, arc deflector 5 is provided with pod apertures 51；Described arc deflector 5 includes three layers, is positioned at
The inner side of the arc deflector 5 in outer layer and intermediate layer is provided with sponge noise reduction layer 6.
The present invention uses the arc deflector structure that Spaced is arranged, and sound wave constantly reflects in the pod apertures of deflector, acoustic energy
Constantly it is consumed, sets up sponge and carry out sound-absorbing, it is achieved flat noise reduction, which effectively reduces the noise of machine room.
Embodiment provided above is the better embodiment of the present invention, is only used for the convenient explanation present invention, not appoints the present invention
What pro forma restriction, has usually intellectual, if without departing from the carried technical characteristic of the present invention in any art
In the range of, utilize the Equivalent embodiments that the done local of disclosed technology contents is changed or modified, and without departing from this
Bright technical characteristic content, all still falls within the range of the technology of the present invention feature.
