Description
Technical field
The utility model is related to railway, road communications vocation field of Environment Protection, and in particular to a kind of big wave sound-absorbing screen.
Background technology
The surface of current sound-absorbing screen is in plane, using filling sucting sound material system in the spraying of metallic plate through hole more than sound-absorbing screen
Form, the surface of abatvoix there are many apertures, and sound enters after aperture, penetrates into inside sound-absorbing material and propagate forward, inhaled
After sound material absorbs, defening effect is reached.When there is high-rise on periphery, for noise isolation, sound barrier can also be set
Compare high, because region area, security and economy are limited, existing sound barrier sets too many truss, support excessively thick and heavy,
Stability is relatively low.And its plane surface can form new conditioned reflex, noise reflection sound wave, this back wave warp are produced
Multiple reflections are excessive, cause noise to be superimposed, and soundproof effect is poor.Therefore, prior art need to be improved.
Utility model content
To overcome the defect present in prior art, now there is provided a kind of big wave sound-absorbing screen, to solve noise reflection
The problem of ripple is excessive.
The utility model provides a kind of big wave sound-absorbing screen, including a sound absorption panel and a sound absorption backboard, the sound absorption
Panel is connected to form a frame chamber with the sound absorption backboard, and the frame intracavitary is provided with the sound absorber for absorbing sound, wherein, it is described to inhale
Sound panel is equally distributed wave shaped panel, and the corrugation length of the wave shaped panel is 130mm, and wave amplitude is 23mm, and institute
State the through hole that sound absorption panel surface runs through the sound absorption panel provided with plural number.
In terms of existing technologies, sound absorption panel is set waviness by the utility model, improves existing sound-absorbing screen
Appearance forrns, it is economical, attractive in appearance, practical, new, screen system make agree with noise circumstance.Making an uproar under various complex environments can be absorbed
Sound, when the sound wave of sound source touches undaform sound barrier, unabsorbed sound wave, which will be dispersed into, multiple has different reflections
The small-scale sound wave in direction, these small-scale sound waves interfere and then accelerate decay, are conducive to improving the sound of sound barrier
Ripple absorbs and elimination effect.
Further, the sound absorption panel runs through the through hole of the sound absorption panel provided with plural number.Through hole is set to be easy to make
Sound enters in sound absorber, greatly enhances the noise reduction of sound-absorbing screen.
Further, the sound absorption backboard includes bottom plate and side plate, and the bottom plate is connected with the side sheet room by rivet clasp.
Make the stability of sound absorption backboard higher.
Brief description of the drawings
Fig. 1 is the assembling schematic diagram of the big wave sound-absorbing screen of the utility model；
Fig. 2 is diagrammatic cross-section after the assembled formation of the big wave sound-absorbing screen of the utility model；
Fig. 3 is the floor map after the assembled formation of the utility model cross-linking sound barrier.
Reference in correspondence Figure of description is with reference to as follows：
Absorb sound panel 1, sound absorption backboard 2, sound absorber 3.
Embodiment
In order that technological means, creation feature, reached purpose and effect that utility model is realized are easy to understand, below
With reference to accompanying drawing, the utility model is expanded on further.
The utility model provides a kind of big wave sound-absorbing screen, is a kind of sound-absorbing screen developed according to sound principle,
As shown in Figures 1 and 2, including a sound absorption sound absorption backboard 2 of panel 1 and one, sound absorption backboard 2 includes bottom plate 21 and side plate 22, bottom plate
Connected between 21 and side plate 22 by professional rivet clasp, sound absorption panel 1 forms a frame chamber after being connected with sound absorption backboard 2, frame intracavitary is set
There is the sound absorber 3 for absorbing sound, sound absorber 3 is fixedly connected with sound absorption panel 1 with sound absorption backboard 2, wherein, sound absorption panel 1 is equal
The wave shaped panel of even distribution, the corrugation length of wave shaped panel is 130mm, i.e., between adjacent crest and adjacent trough
Distance respectively 130mm, wave amplitude is 23mm, and the size of wave amplitude is conducive to the reflection-absorption of noise, 23mm wave amplitude is advantageous
In the size of reflection sound wave, will not occur the phenomenon of stability reduction, and sound absorption panel is run through in sound absorption panel 1 surface provided with plural number
1 through hole（Do not show in figure）, it is easy to make sound enter in inner sound absorption body 3 to be absorbed.
Specifically, in conjunction with shown in Fig. 3, when sound wave touches sound absorption panel 1, partial noise is entered by through hole to be inhaled
Sound body 3, sound absorber 3 is made up of reinforcement compact material, generally loose structure, can effectively absorb noise, and acoustic absorptivity is high
Up to 0.85, and the sound wave of another part circles round among crest, so as to weaken, disappear, with good absorbing sound and lowering noise effect.
The utility model improves the appearance forrns of existing sound-absorbing screen, and economic, attractive in appearance, practical, novelty, screen system is made to agree with
Noise circumstance.Many through holes are added on the sound absorption panel of big wave sound-absorbing screen, greatly enhance the noise reduction of sound-absorbing screen, energy
Absorb the noise under various complex environments.When the sound wave of sound source is with sensing undaform sound barrier, unabsorbed sound wave is just
Multiple small-scale sound waves for there are a different reflection directions can be dispersed into, these small-scale sound waves interfere and then accelerate to decline
Subtract, be conducive to improving wave absorption and the elimination effect of sound barrier.
The specific embodiment of utility model is described above.It is to be appreciated that utility model is not limited to
Above-mentioned particular implementation, wherein the equipment and structure be not described in detail to the greatest extent are construed as being given with the common mode in this area
To implement；Those skilled in the art, which can make various deformations or amendments within the scope of the claims and make, some simply to push away
Drill, deform or replace, this has no effect on the substantive content of utility model.
