Description
Technical field
The present invention relates to storage station's noise reduction technology field, particularly a kind of anti-acoustic device of storage station.
Background technology
The noise source of storage station is mainly unit acts on generation in the process of running noise between runner and current, due to
Hydroenergy storage station high water head, high-revolving feature, so the noise produced during unit operation is very big, have a strong impact on work on the spot
The on duty of personnel, service work and damaged to healthy.
The content of the invention
Shortcoming it is an object of the invention to overcome prior art, there is provided a kind of effective elimination, the accumulation of energy of insulating noise electricity
Stand and use anti-acoustic device.
The purpose of the present invention is achieved through the following technical solutions：A kind of anti-acoustic device of storage station, it includes being used for
The accommodation chamber of accommodating unit, described accommodation chamber is the square casing being arranged on ground, and described square casing includes four
Side wall and a top surface, described side wall and top surface are by along noise reduction parietal layer, the sound insulation cotton layer that from inside to outside direction sets gradually
Constituted with vacuum parietal layer, described noise reduction parietal layer is masonry walls, and bloop is evenly distributed with described masonry walls, and bloop is passed through
Noise reduction parietal layer is worn, described bloop is included along the first conical cavity, rectangular cavity that from inside to outside direction is sequentially communicated and the second cone
Shape chamber is constituted, and the internal diameter of the first conical cavity and the second conical cavity is and is gradually reduced along direction from inside to outside, described vacuum
The wall body with vacuum tightness cavity volume that parietal layer is surrounded for metallic plate.
Noise consumes a part of acoustic energy during passing through the first conical cavity, dashing forward due to section when sound wave enters rectangular cavity
So become the big impedance changed during acoustic propagation, sound wave produces reflection, interference, acoustic energy, Sound-proof material and vacuum wall are reduced again
Layer further absorbs and cut-off Acoustic Wave Propagation, so as to reach the effect for preferably abating the noise.
Preferably, the width of described rectangular cavity is more than the outermost internal diameter of the first conical cavity and equal to the second conical cavity most
The internal diameter of inner side.
Door is provided with described side wall, the door is the door body with vacuum tightness cavity.
The present invention has advantages below：
The present invention completely cuts off unit noise by setting the accommodation chamber with sound-deadening and noise-reducing function, on-site noise drop when equipment is run
It is low, meet labour hygiene standard, be conducive to the scene of being engaged on duty, maintenance staff healthy.Accommodation chamber wall body knot
Structure is simple, low cost, is suitable to popularization and application.
Brief description of the drawings
Fig. 1 is structural representation of the invention.
Fig. 2 is cross section structure schematic diagram of the invention.
Fig. 3 is the partial enlarged drawing in I portions in Fig. 2
In figure, 1- noise reduction parietal layers, 2- sound insulation cotton layers, 3- vacuum parietal layers, 4- bloops, the conical cavities of 5- first, 6- rectangular cavities, 7-
Two conical cavities, 8-, 9- sides wall, 10- top surfaces.
Specific embodiment
The present invention will be further described below in conjunction with the accompanying drawings：
As shown in Figure 1 and Figure 2, it includes the accommodation chamber for housing unit, described accommodation chamber be arranged at it is square on ground
Housing, described square casing includes four side walls 9 and a top surface 10, and described side wall 9 and top surface 10 are by edge from introversion
Noise reduction parietal layer 1, sound insulation cotton layer 2 and the vacuum parietal layer 3 that outer direction sets gradually are constituted, and described noise reduction parietal layer 1 is masonry walls, institute
Bloop 4 is evenly distributed with the masonry walls stated, bloop 4 runs through noise reduction parietal layer 1, and described bloop 4 includes edge from introversion
The first conical cavity 5 that outer direction is sequentially communicated, the conical cavity 7 of rectangular cavity 6 and second are constituted, the first conical cavity 5 and the second conical cavity 7
Internal diameter be and be gradually reduced along direction from inside to outside, described vacuum parietal layer 3 for metallic plate surround with vacuum tightness
The wall body of cavity volume.
Noise through consuming a part of acoustic energy during the first conical cavity 5, due to section when sound wave enters rectangular cavity 6
Suddenly the big impedance changed during acoustic propagation is become, sound wave produces reflection, interference, acoustic energy, Sound-proof material and vacuum are reduced again
Parietal layer 3 further absorbs and cut-off Acoustic Wave Propagation, so as to reach the effect for preferably abating the noise.
Preferably, the width of described rectangular cavity 6 is more than the outermost internal diameter of the first conical cavity 5 and equal to the second conical cavity
The internal diameter of 7 most inner sides.
Door 8 is provided with described side wall 9, the door 8 is the door body with vacuum tightness cavity.
The present invention completely cuts off unit noise by setting the accommodation chamber with sound-deadening and noise-reducing function, and scene is made an uproar when equipment is run
Sound reduction, meets labour hygiene standard, is conducive to the scene of being engaged on duty, maintenance staff healthy.Accommodating locular wall
Body simple structure, low cost, are suitable to popularization and application.
