Abstract
The utility model discloses an anti-diffraction, high-efficient and sound-absorbing screen body. The existing sound-absorbing screen body has the problem of narrow noise absorbing band, etc. The utility model is characterized in that the anti-diffraction, high-efficient and sound-absorbing screen body comprises a base and a frame, wherein the lower part of the frame is provided with a glass screen plate. The positive end surface of the upper part of the frame is provided with a folded plate type micro-perforated plate of an inner and an outer layers, a backing plate is matched and arranged on the rear end surface of the upper part of the frame, and the top of the frame is fixed with an anti-diffraction sound-absorbing body composed of a fan-shaped micro-perforated plate of an inner and an outer layers, a middle partition board in the middle in a fan-shaped cavity and a left and a right side plates. The anti-diffraction, high-efficient and sound-absorbing screen body of the utility model has the advantages of high noise-reducing efficiency, favorable landscape effects, glare prevention, stable performance, wide absorption band and high sound-absorption coefficients. The anti-diffraction, high-efficient and sound-absorbing screen body of the utility model is suitable to be used at occasions, such as road traffics, buildings, public mechanical equipment, etc.
Description
Technical field:
The utility model relates to a kind of gobo body, particularly relates to the efficient gobo body of a kind of anti-diffraction.
Background technology:
Development along with urban road construction, speedway, sky way constantly reproduces, simultaneously, various vehicles particularly run quickly at road also in cumulative year after year, car on sky way and the speedway all can send the noise of different frequency, both polluted clean quiet environment on every side, have a strong impact on the peacefulness in city again, though, road traffic noise is polluted certain measure of having taked, at road, sky way and speedway both sides are provided with barriers, but it relatively insulates against sound, and fails to eliminate noise, fundamentally do not go yet to deal with problems, afterwards, the gobo body had also appearred, no doubt, this is being a a progressive step aspect elimination noise,, this is in reduction, during high-frequency noise, be to have brought into play active and effective effect, and go back some shortcoming for low-frequency noise, unsatisfactory.
Summary of the invention:
The purpose of this utility model is to provide a kind of improved anti-diffraction efficient gobo body, and it not only can absorb the noise of middle and high frequency effectively, and, can also absorb low-frequency noise efficiently, simultaneously, effect such as anti-dazzle is arranged, have a wide sphere of vision.
In order to realize that above-mentioned purpose the utility model proposes following design scheme: the efficient gobo body of anti-diffraction of the present utility model has base, described base is put on the shelf and is provided with a framework, be packaged with a backboard on the described framework upper rear end face, pair of lamina folded plate type microperforated panel is installed on the positive end face of described framework upper, described framework bottom is equipped with a glass panel, described frame roof device has an anti-diffraction sound absorber that is fan shape, described anti-diffraction sound absorber is by the described ectonexine microperforated panel that is fan shape, median septum in the middle of the cavity of the described ectonexine microperforated panel that is fan shape and about other plate form, aperture on the described outer folded plate type microperforated panel is 0.3～0.8 millimeter, the micropore perforated percentage is 3.6%, aperture on the described internal layer folded plate type microperforated panel is 0.2～0.3 millimeter, the micropore perforated percentage is 0.78%, aperture on the described outer microtube perforated plate that is fan shape is 0.3～0.8 millimeter, the micropore perforated percentage is 3.6%, aperture on the described internal layer microperforated panel that is fan shape is 0.2～0.3 millimeter, and the micropore perforated percentage is 0.78%.
Because the utility model has improved the efficient gobo body of existing anti-diffraction, used the micropore perforated plate and absorbed sound theoretical harmony around theory, the anti-diffraction sound absorber and the transparent screen that use double-deck folded plate type microperforated panel soundabsorbing construction, are fan shape reasonably make up, having solved sound barrier not only absorbs sound but also transparent, and absorbent lined barrier and the combination of fan-shaped sound absorber have noise reduction preferably, especially comprise the diffraction sound of low frequency, therefore, absorption band is wide.
Description of drawings:
Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.
Fig. 1 is the structural representation of the efficient gobo body of anti-diffraction of the present utility model.
Fig. 2 is that schematic diagram is looked on the left side of Fig. 1.
