Embodiment 1
[0053] like 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 for ...
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
This application relates to noise absorbing equipment. In order to solve the problem that the sound insulation wall is not easy to disassemble and assemble in the prior art, a road noise sound absorbing panel is provided, including a supporting component and a noise absorbing component; the supporting component is used as a positioning basis; the noise absorbing component includes The rotating shaft of the positioning part of the sound-absorbing folding board; the sound-absorbing folding board has a positioning angle, and there are multiple sound-absorbing folding boards; the rotating shaft is used as the positioning basis of the sound-absorbing folding board; the rotating shaft is horizontally fixed at the bottom of the left frame; The sound-absorbing folded plates are arranged parallel to the axial direction of the rotating shaft; the sound-absorbing folded plates can be completely accommodated into the left frame when they rotate relative to the rotating shaft, and can be unfolded into a rectangle when the sound-absorbing folded plates are rotated away from the left frame. The sound-absorbing panel is convenient for disassembly, transportation and storage, and can be quickly installed for road sections that temporarily require sound insulation and noise reduction, and can perform effective sound insulation and noise reduction.
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...
