Description

Technical Field

[0001] The utility model relates to the technical field of noise reduction barriers, in particular to a sound barrier with a multi-level noise reduction structure. Background Art

[0002] Sound barriers are mainly used for sound insulation and noise reduction on roads, highways, elevated composite roads and other noise sources. They are divided into pure sound insulation reflective sound barriers and composite sound barriers that combine sound absorption and sound insulation. However, sound barriers are usually assembled and produced with sound insulation layers, which can passively reduce the noise of sound. The sound barriers on the market are usually produced one-to-one according to the actual use scenarios before leaving the factory. It is impossible to increase or reduce the sound insulation layer within a certain range according to the use needs, which undoubtedly reduces the actual use scenarios of the device.

[0003] For example, Chinese patent announcement No. CN217839772U discloses a sound barrier with a noise reduction function. When in use, personnel can adjust the noise reduction level of the barrier according to actual on-site usage conditions. Personnel add a noise reduction material plate to the inside of the installation groove. During the adding process, the personnel pushes the slider outward, driving the spacer to move, so that the cylinder is separated from the inside of the socket. Then the personnel moves the installation box and drives the support plate to move upward through the connecting rod, so that the noise reduction material plate contacts the support plate. Then the personnel slowly moves the installation box downward and moves the noise reduction material plate to the bottom of the inner cavity of the installation groove, thereby avoiding damage caused by collision between the noise reduction material plate and the inner cavity of the installation groove during installation.

[0004] However, the sound barrier with noise reduction function in the above application is added with noise reduction plates by means of later installation, which will inevitably cause gaps between the noise reduction plates, thereby reducing the noise reduction efficiency. Therefore, there are certain limitations.

[0005] To this end, we urgently need to provide a sound barrier with a multi-level noise reduction structure. Utility Model Content

[0006] The purpose of the utility model is to provide a sound barrier with a multi-level noise reduction structure to solve the problem that the sound barrier with noise reduction function proposed in the above-mentioned background technology adds noise reduction plates to the sound barrier by means of later installation, which inevitably causes gaps between the noise reduction plates, thereby reducing the noise reduction efficiency.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a sound barrier with a multi-level noise reduction structure, comprising a sound barrier board, a noise reduction device is arranged inside the sound barrier board, and a splicing device is arranged on the right side of the sound barrier board.

[0008] The noise reduction device includes a silencer pipe, silencer cotton, and a silencer spring. Several of the silencer pipes are evenly installed inside the sound barrier board, several of the silencer cottons are adhered to the inner wall of the silencer pipe, and several of the silencer springs are installed inside the silencer pipe. The silencer springs are used to absorb noise waves and convert them into kinetic energy to reduce the noise. The noise is further absorbed by the silencer cotton on the inner wall of the silencer pipe to improve the silencer effect.

[0009] A further improvement is that the interior of the sound barrier board is a cavity structure, the noise reduction device is installed inside the sound barrier board, and the gap between the noise reduction device and the sound barrier board is filled with a sound insulation board.

[0010] A further improvement is that the sound insulation board is made of a foam plastic board, which has a very loose structure and contains a large number of air cells inside, so it has a very good sound insulation effect. Secondly, due to the cushioning properties of the material, the foam plastic board can effectively absorb and disperse sound waves, thereby achieving a good sound insulation effect.

[0011] A further improvement is that splicing grooves are respectively provided at the upper and lower ends of the right side of the front side of the sound barrier board, and plug-in holes are provided on the right sides of the upper and lower ends of the sound barrier board and communicate with the splicing grooves, and a spring compartment is provided inside the plug-in holes.

[0012] A further improvement is that the splicing device includes a splicing block, a plug-in rod, and a tension spring. The two splicing blocks are respectively fixedly connected to the upper and lower ends of the left outer surface of the sound barrier board, the two plug-in rods are respectively plugged into the inside of the plug-in hole, and the two tension springs are respectively installed in the inside of the spring compartment and are installed around the outer surface of the plug-in rod.

[0013] A further improvement is that a plug-in hole is also penetrated through the outer surface of the splicing block, and the plug-in rod is plugged into the inside of the plug-in hole. When installing the splicing sound barrier panels, first pull the plug-in rod to pull it out from the inside of the plug-in hole, and at the same time compress the tension spring, and then insert the splicing block on the other sound barrier panel into the inside of the splicing groove on the right side of the first sound barrier panel, and then release the plug-in rod. The tension spring resets under its own elastic action, thereby pulling the plug-in rod to insert into the inside of the plug-in hole on the splicing block, thereby quickly completing the installation of the two sound barrier panels and improving the installation efficiency.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. The sound barrier with a multi-level noise reduction structure absorbs noise waves and converts them into kinetic energy through silencer springs, thereby reducing the noise. The silencer cotton on the inner wall of the silencer pipe further absorbs the noise, thereby improving the silencer effect.

[0016] 2. This sound barrier with a multi-level noise reduction structure has a very loose structure of the foam plastic board and contains a large number of air cells inside, so it has a very good sound insulation effect. Secondly, due to the cushioning properties of the material, the foam plastic board can effectively absorb and disperse sound waves, thereby achieving a good sound insulation effect.

[0017] 3. When installing the spliced ​​sound barrier panels, the sound barrier with a multi-stage noise reduction structure first pulls the plug-in rod, then inserts the splicing block on the other sound barrier panel into the splicing groove on the right side of the first sound barrier panel, and then releases the plug-in rod. The tension spring resets under its own elastic action, thereby pulling the plug-in rod into the plug-in hole on the splicing block, thereby quickly completing the installation of the two sound barrier panels and improving the installation efficiency.
