Description

Technical Field

[0001] The utility model relates to the technical field of sound barriers, in particular to a sound barrier with multiple sound-absorbing structures. Background Art

[0002] A sound barrier is a wall-like structure with sound insulation function, which can reduce the impact of noise in the recipient area. It is suitable for noise prevention in elevated highways, urban light rail and subway. It is a sound insulation and noise reduction facility in modern cities. When sound waves encounter a sound barrier during propagation, three phenomena, reflection, transmission and diffraction, will occur. The sound barrier can prevent the propagation of direct sound and make the transmitted sound sufficiently attenuated to achieve the purpose of noise reduction.

[0003] However, it still has some disadvantages. For example, the purpose of sound insulation and noise reduction is achieved through sound-absorbing panels. Since the internal material of the sound-absorbing panels is mostly filled with sound-absorbing cotton, setting a layer of sound-absorbing cotton will reduce the sound insulation effect of the sound barrier. In addition, multiple sets of screws are inserted into the sound barrier panel from the front of the mounting structure to achieve the purpose of fixing the combination. However, the overall assembly of multiple sets of screws is time-consuming and relatively cumbersome.

[0004] In order to solve the above problems, a sound barrier with multiple sound-absorbing structures is proposed in this application. Utility Model Content

[0009] Preferably, the reflective plate is fixed at the upper ends of the main plate and the sound-absorbing plate, the reflective plate is arranged in an arc shape, and the number of the sound-absorbing holes is arranged in a plurality of groups.

[0010] Preferably, the lower end of the roller is slidably connected to the inner cavity of the sliding groove, and one side of the first connecting bolt passes through the inner cavity of the connecting seat and extends to the inner cavities on both sides of the fixing plate.

[0011] Preferably, the number of the limiting plates is two groups, and one side of the second connecting bolt penetrates the inner cavity of the limiting plate and is detachably connected to the inner cavity of one side of the connecting seat and the inner cavity of one side of the fixing plate.

[0012] Preferably, the protective net is located on the outside of the sound absorbing panel.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The utility model facilitates the disassembly and installation of the sound barrier through the cooperation of the connecting seat, the fixing plate, the limiting plate, the sliding groove, the first connecting bolt, the second connecting bolt and the roller. The roller at the lower end of the fixing plate is slid into the sliding groove to align the two sides of the fixing plate with the connecting seat, and then the first connecting bolt is used to fix the two sides of the connecting seat and the fixing plate. When the limiting plate is installed at the two ends of the connecting seat, the two ends of the fixing plate and the connecting seat are fixedly connected by the second connecting bolt, which improves the stability of the connection and installation, reduces the accumulation of dust between the installation gaps and the damage to the two ends of the connecting seat and the fixing plate, and improves the protection.

[0015] The utility model plays a role of protecting against dust through the protective net, reduces damage to the sound barrier, prolongs the service life of the sound barrier, and can prevent clogging due to long-term use. The reflective plate can reflect the sound waves, and when the sound waves enter the interior of the vacuum chamber, the transmission speed is greatly reduced, thereby attenuating them. The microporous structure inside the two layers of sound-absorbing cotton absorbs the residual sound waves, and the multiple structures are used to weaken the sound, which can effectively reduce the transmission of sound waves, improve the shielding efficiency, and minimize the propagation of noise. The generated noise can enter the interior of the sound-absorbing board through the silencing holes, and then the diffusion of the sound can be prevented through the interior of the sound-absorbing board, thereby achieving the purpose of well controlling and eliminating noise.
