Abstract
A continuous arc steel plate reflecting sound-proof device comprises high-quality continuous arc steel plates. A concave face of each continuous arc steel plate faces a noise source. The continuous arc steel plates are fixed on a metal truss. The area of a sound-proof operating unit is reduced greatly. The structure of continuous arc steel plates can convert waveform. Great reduction of the area of the sound-proof operating unit avoids mutual coupling effect. The continuous arc structure changes a wave path of reflected waves. A sound-proof operating face having an interfering function is formed and converts the waveform, loss of acoustic energy is increased, and the reflected wave is avoided returning to a vehicle.
Description
Technical field environmental protection
The present invention discloses a kind of device of continuous circular arc steel plate reflection sound insulation, and especially continuous circular arc steel plate is fixed on metal truss, avoids coupling, increased the quality of sound insulation mechanism, form simultaneously and there is the sound insulation work plane of interfering function, produce waveform and change, increase the loss of acoustic energy.Avoid back wave to get back to car body.
Background technology
At present, known sound barrier acoustic isolater upwards stacks use by large-area cell cube, produces coupling (influencing each other) effect, causes acoustic energy to strengthen; Form of structure perpendicular to ground configuration makes back wave get back to again the car body travelling, and the energy of noise is further strengthened, and has lost the function of noise reduction.
Summary of the invention
The continuous circular arc steel plate that service property (quality) of the present invention is higher, concave surface is used towards noise source, and is fixed on metal truss, and the area of sound insulation working cell is significantly reduced; The form of structure of continuous circular arc steel plate can produce waveform and change.
The invention has the beneficial effects as follows:
The area of sound insulation working cell is significantly reduced to the coupling that can avoid mutual; The wave-path of continuous circular arc structural change back wave, forms and has the sound insulation work plane of interfering function, and waveform is changed, and increases the loss of acoustic energy, avoids back wave to get back to car body.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is the three-dimensional drawing of the device bottom of continuous circular arc steel plate reflection sound insulation;
Fig. 2 is the lateral view of the device of continuous circular arc steel plate reflection sound insulation.
In figure: (1) steel truss, (2) continuous circular arc steel plate.
The specific embodiment
In enforcement, the trough of the continuous circular arc steel plate (2) of moulding is welded on steel truss (1) and makes sound insulation assembly, use on sound barrier, concave surface is used towards noise source.
Claims (2)
