[0002] Highway noise reduction devices refer to equipment installed around roads to reduce the spread of traffic noise. These devices usually include sound barriers, sound-absorbing walls, soundproof screens and green barriers. Sound barriers and sound-absorbing walls are made of specific materials and can effectively block and absorb the noise generated by vehicles. Soundproof screens are usually installed around bridges or elevated roads, and use their unique structure and materials to reduce the spread of noise to the surrounding environment. The main purpose of noise reduction devices is to improve the quality of life of residents around roads and reduce the health and psychological impacts caused by traffic noise.

[0003] Most existing highway noise reduction devices adopt an integrated design, which makes it difficult to disassemble and replace them when damaged. At the same time, the existing noise reduction curtain wall structure is relatively simple and is easily corroded and damaged after long-term use, resulting in a significant reduction in the noise reduction effect and a shortened service life. This integrated design poses certain challenges in maintenance and repair, which not only increases maintenance costs but may also have a negative impact on the environment around the highway. In addition, the single structural design lacks flexibility and is difficult to adapt to different environments and needs, further limiting its widespread application and long-term use. In order to improve the performance and durability of noise reduction devices, it is urgent to develop more convenient, durable and versatile noise reduction solutions. Utility Model Content

[0024] As Figure 1 and Figure 2 shown, the noise reduction device for roads includes a concrete base 1, a sound insulation curtain wall 2 fixedly connected above the concrete base 1. The sound insulation curtain wall 2 is integrally divided into a vertical section plate body 11 and an arc section plate body 12. The sound absorption support plates 22 are evenly distributed on the vertical section plate body 11 and the arc section plate body 12. The sound insulation curtain wall 2 includes an outer panel 21 placed above the concrete base 1. A plurality of sound absorption support plates 22 are movably connected to the outer panel 21. A surface treatment layer 23 is provided on the side of the outer panel 21 facing away from the sound absorption support plates 22.

[0025] In this embodiment, by providing the sound insulation curtain wall 2 placed above the concrete base 1, the sound absorption support plates 22 movably installed on the outer panel 21 can not only achieve quick disassembly and assembly, but also support the whole sound insulation curtain wall 2. The outer surface layer of the outer panel 21 is provided with a surface treatment layer 23 to ensure the corrosion resistance of the outer panel 21 as an external frame and increase the service life of the device.

[0026] As Figure 3As shown, T-shaped sliding grooves 24 are evenly provided on the vertical section plate body 11 and the arc section plate body 12. Clamping plates 25 corresponding to the sliding grooves 24 are fixedly connected to both ends of the sound-absorbing support plate 22. The sound-absorbing support plate 22 includes an inner support plate 26 close to the sliding groove 24, a mineral wool layer 27 on the other side of the inner support plate 26, and an outer support plate 28 on the side of the mineral wool layer 27 facing away from the inner support plate 26. A number of through holes 29 that are evenly distributed and penetrate through themselves are provided on both the inner support plate 26 and the outer support plate 28. The outer panel 21 is made of one of a metal plate or plexiglass, and the surface treatment layer 23 is one of an anti-corrosion coating or an anti-graffiti coating. A drainage channel is also provided on the concrete base 1. The inner support plate 26 and the outer support plate 28 are made of high-strength steel plates.

[0027] In this implementation scheme, the design of the T-shaped sliding groove 24 and the clamping plate 25: facilitates the installation and disassembly of the sound-absorbing support plate 22, greatly improves the convenience of maintenance and replacement, and ensures that the sound-absorbing support plate 22 remains stable during use and is not prone to loosening or falling off.

The middle mineral wool layer 27 has excellent sound-absorbing performance, effectively reducing noise. This sandwich structure not only ensures strength but also achieves good sound insulation effects. The design of the through holes 29: The through holes 29 evenly distributed on the inner and outer support plates increase the opportunity for sound waves to enter the mineral wool layer, improve the sound-absorbing efficiency, and also reduce the overall weight, facilitating installation and maintenance. The material selection of the outer panel 21: The use of a metal plate or plexiglass provides good weather resistance and sound wave reflection ability, and these materials are also easy to clean and maintain. The surface treatment layer 23: The anti-corrosion coating increases the durability of the device and extends the service life, and the anti-graffiti coating helps to keep the device beautiful and reduces daily maintenance work. The drainage system on the concrete base 1: effectively prevents water accumulation, protects the entire device from water damage, and extends the service life of the entire system. The combination of the vertical section plate body 11 and the arc section plate body 12: This design can better adapt to different terrain and road conditions. The arc section can more effectively reflect and absorb sound waves, improving the noise reduction effect.
