Embodiment 1

[0053] Such as figure 1 As shown, this is as figure 1 As shown, a road noise sound-absorbing panel of the present application includes a support assembly 100 and a noise-absorbing assembly 200;

[0054] Support assembly 100, lower frame 110, left frame 120;

[0055] Noise absorbing assembly 200, sound-absorbing folding plate 210, sound-absorbing bag layer 211, air bag part 211-1, water bag part 211-2, one-way valve 211-3, modeling plate 212, positioning part 220, bushing 221, coil spring 222 , the rotating shaft 223, the elastic rope 230, the guiding and fixing assembly 231;

[0056] A power assembly 300 , a windward plate 310 , and a spring 320 .

[0057] The support assembly 100 serves as a positioning basis;

[0058] The support assembly 100 includes a lower frame 110 and a left frame 120;

[0059] The lower frame 110 is a rectangular parallelepiped stainless steel plate with grooves on the upper surface; vertical threaded holes can be provided on the lower frame 110 f...

Embodiment 2

[0080] In actual use, there is a gap between adjacent sound-absorbing panels when the sound-absorbing folded panel 210 is unfolded, and noise may leak through the gap, weakening the sound-absorbing effect. Therefore, the sound-absorbing capsule layer 211 is added;

[0081] The sound-absorbing folded panel 210 includes a sound-absorbing capsule layer 211 and a modeling panel 212;

[0082] The modeling board 212 is a hard sound insulation board, which is used to form and maintain the shape of the sound-absorbing folding board 210;

[0083] The sound-absorbing capsule layer 211 is used for sound-absorbing and filling the gap between adjacent sound-absorbing folded panels 210;

[0084] The sound-absorbing capsule layer 211 is a rubber capsule body, and the surface of the sound-absorbing capsule layer 211 is distributed with sound-absorbing concave points, which can improve the sound-absorbing effect; at the same time, when the sound-absorbing folding plate 210 is retracted and op...

Embodiment 3

[0088] The solutions of Embodiments 1 and 2 have limited sound insulation effects on some high-decibel noises in the actual measurement. Sound waves decay very quickly when they encounter water with air bubbles. The formation of air bubbles with a volume ratio of about 0.5-2% in water can achieve 75-85% noise attenuation.

Abstract

The invention relates to noise absorption equipment, aims to solve the problem that a sound insulation wall is inconvenient to disassemble and assemble in the prior art, and provides a road noise absorption board which comprises a supporting assembly and a noise absorption assembly. The supporting assembly serves as a positioning foundation; the noise absorption assembly comprises a sound absorption folding plate positioning part rotating shaft; each sound-absorbing folding plate is provided with a positioning angle, and a plurality of sound-absorbing folding plates are arranged; the rotating shaft is used as a positioning foundation of the sound-absorbing folding plate; the rotating shaft is horizontally fixed at the bottom end of the left frame; the multiple sound absorption folding plates are arranged in parallel in the axial direction of the rotating shaft. The sound absorption folding plate rotates relative to the rotating shaft, can be completely stored into the left frame, and can be unfolded into a rectangle when rotating in the direction away from the left frame. The sound-absorbing plate is convenient to disassemble, assemble, transport and store, and can be quickly mounted on a road section which temporarily needs sound insulation and noise reduction, so that effective sound insulation and noise reduction are realized.

Description

technical field [0001] The invention relates to noise absorbing equipment, in particular to a noise absorbing board used in roads. Background technique [0002] Sound-absorbing panels (sound-insulating panels) are wall-type structures installed on both sides of the road to reduce the impact of driving noise on nearby residents. [0003] The existing sound-absorbing panel is an integral structure, which needs to be fixedly installed on both sides of the road. In some temporary construction sites or road sections with short-term traffic surges, the sound-absorbing panels of this integral structure are not suitable for both sides. However, noise in these areas can seriously affect [0004] Normal order for nearby residents and businesses. Therefore be badly in need of a kind of road noise sound-absorbing panel that is convenient to dismount and move. Contents of the invention [0005] The embodiment of the present application provides a road noise sound-absorbing panel, w...
