Description

Technical Field

[0001] This utility model relates to the field of sound barrier technology, and in particular to a highway sound barrier panel. Background Technology

[0002] A sound barrier is a sound-blocking structure with sufficient surface density located between a sound source and a receiver. By constructing a sound barrier of limited length in localized areas on both sides of the sound source, the operating noise of the sound source can be significantly attenuated during propagation, thereby reducing the noise impact in the receiver's area and reducing the disturbance to nearby residents caused by passing vehicles on highways.

[0003] Patent application number CN201821066138.1 discloses a sound-absorbing panel for a sound barrier, comprising a perlite layer with an edging layer around its perimeter. The perlite layer includes a sound-absorbing surface and a sound-absorbing back surface, with a sound-absorbing backplate layer on the back surface. A wire mesh is fixedly installed on the backplate layer, and a protective layer is provided on the wire mesh. When laying such sound-absorbing panels, they are often assembled onto supports on both sides of the road using a plug-in method. This plug-in method facilitates the maintenance and replacement of the sound barrier panels. However, during long-term use, affected by vehicle noise and wind vibration, the plug-in joints between the panels are prone to vertical, horizontal, or front-back swaying, leading to unstable installation and requiring optimization.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0021] according to Figures 1-5 As shown, this embodiment proposes a highway sound barrier panel, including a base 1, a plurality of columns 2 on the top of the base 1, the columns 2 being fixedly connected to the base 1, and a plurality of panels 3 being placed between two adjacent columns 2; The left and right sides of the column 2 are provided with assembly slots 21, the left and right ends of the plate 3 are inserted into the assembly slots 21 and are slidably connected to the assembly slots 21, and a positioning slot structure is provided between two adjacent plates 3.

[0022] During installation, the base 1 is fixed on both sides of the road, the column 2 is fixed on the upper end of the base 1, and the plate 3 is placed between two adjacent columns 2. The left and right ends of the plate 3 will be inserted into the assembly groove 21 opened on the side of the column 2. The assembly groove 21 restricts the left and right sway of the plate 3 by cooperating with the plate 3. The positioning groove is set at the joint of the two plates 3 to increase the stability and firmness of the plate 3 after assembly.

[0023] The top of the column 2 is provided with a pivot plate 5, which is rotatably connected to the column 2. The left and right ends of the pivot plate 5 are provided with positioning pressure plate structures to prevent the plate 3 from shaking up and down.

[0024] After the assembly of plate 3 is completed, rotate the pivot plate 5 at the top of column 2. The pivot plate 5 will move the positioning pressure plate structure above plate 3 by rotating. By limiting plate 3 from the top, the plate 3 is prevented from shaking up and down, and the stability of plate 3 after assembly is further improved.

[0025] Regarding the positioning groove structure: The positioning groove structure includes a positioning slot 31 and a positioning protrusion 34. The positioning slot 31 is located at the bottom of the plate 3, and the positioning protrusion 34 is fixedly located at the top of the plate 3. The positioning protrusion 34 and the positioning slot 31 are interlocked. When the plates 3 are placed between two columns 2 and stacked sequentially, the positioning protrusion 34 on the top of the lower plate 3 will engage with the positioning slot 31 at the bottom of the other plate 3. The positioning slot 31, by engaging with the positioning protrusion 34, restricts the back-and-forth swaying of the plate 3 and improves the stability of the plate 3 during installation.

[0026] Regarding the positioning pressure plate structure: The positioning pressure plate structure includes an arc-shaped positioning plate 51, which is fixedly installed at the left and right ends of the rotating pin plate 5. An arc-shaped slot A32 is provided on the top of the plate body 3, and the arc-shaped slot A32 is slidably connected to the arc-shaped positioning plate 51. An arc-shaped slot B22 is provided on the upper end of the column 2, and the arc-shaped slot B22 is connected to the arc-shaped slot A32. The arc-shaped slot B22 is slidably connected to the arc-shaped positioning plate 51. A positioning pin structure for limiting the rotation of the rotating pin plate 5 is provided on the upper end of the plate body 3.

[0027] After the assembly of plate 3 is completed, the top of plate 3 is flush with the top of column 2. The arc-shaped slot B22 on the top of column 2 is connected to the arc-shaped slot A32 on the top of plate 3. Rotate the pivot plate 5 to rotate both ends of the pivot plate 5 to the top of plate 3. The arc-shaped positioning plates 51 on the left and right ends of the pivot plate 5 will be inserted into the arc-shaped slot A32 through the arc-shaped slot B22. With the help of the pivot plate 5, the plate 3 is limited from the top of the plate 3, so that the plate 3 cannot be detached from the top of column 2. This ensures good safety and facilitates the assembly and disassembly of plate 3.

[0028] More specifically, the positioning pin structure includes a pin hole 33 and a spring groove 6. The pin hole 33 is located at the upper end of the plate 3, and the spring groove 6 is located at the lower end of the pivot plate 5. A spherical pin 61 is provided in the spring groove 6. The spherical pin 61 engages with the pin hole 33 and is slidably connected to the spring groove 6. A spring 62 is fixedly installed in the spring groove 6, and the lower end of the spring 62 is fixedly connected to the spherical pin 61.

[0029] When the rotating pin plate 5 is rotated, after the arc-shaped positioning plate 51 is screwed into the arc-shaped slots B22 and A32, the spherical pin 61 at the bottom of the rotating pin plate 5 will pop out from the spring groove 6 and thus get stuck in the pin hole 33 opened at the top of the plate body 3. The spherical pin 61 limits the rotation of the rotating pin plate 5 by cooperating with the pin hole 33, so that the arc-shaped positioning plate 51 will not be screwed out from the arc-shaped slots A32 and B22 due to the vibration of the column 2 and the plate body 3 itself. The setting of the spherical pin 61 ensures that the rotating pin plate 5 will not get stuck when the plate body 3 is disassembled and assembled.

[0030] In the preferred embodiment, to facilitate the rotation of the pivot plate 5, a handle 52 is provided at the upper end of the pivot plate 5, and the handle 52 is fixedly connected to the pivot plate 5.

[0031] It is worth explaining in detail that the plate 3 has several air holes 4, which are arranged in a rectangular array. The air holes 4 allow air to circulate, reducing the air pressure difference on both sides of the plate 3. When sound waves are incident, the air vibrates and rubs within the holes, converting sound energy into heat energy. It is particularly effective in absorbing mid-to-high frequency noise, thus improving the noise reduction of the plate 3.

[0032] In the preferred embodiment, the column 2 is equipped with fixing bolts, which pass through the assembly groove 21 and are threadedly connected to the bolt holes at both ends of the plate 3. To increase the structural stability of the plate 3 after installation, the plate 3 can be fixed to the column 2 by bolt connection. Of course, other methods can also be used for fixing besides bolt connection, which will not be elaborated further.

[0033] How this application works: During installation, the base 1 is fixed to both sides of the road, the column 2 is fixed to the upper end of the base 1, and the plate 3 is placed between two adjacent columns 2. The left and right ends of the plate 3 will insert into the assembly slots 21 opened on the side of the column 2. The assembly slots 21 restrict the left and right sway of the plate 3 by cooperating with it. The positioning slots are set at the mating points of the two plates 3 to increase the stability and firmness of the plate 3 after assembly. After the plate 3 is assembled, the pivot plate 5 at the top of the column 2 is rotated. The pivot plate 5 will move the positioning pressure plate structure above the plate 3 by rotating, thereby limiting the plate 3 from the top and preventing the plate 3 from swaying up and down, further improving the firmness of the plate 3 after assembly.
