Description

Technical Field

[0001] This utility model relates to the field of noise control components, and in particular to a noise control component for urban road traffic. Background Technology

[0002] With the acceleration of urbanization, traffic congestion has become a common problem in many cities, leading to traffic noise pollution, which seriously affects the quality of the urban living environment. Residential areas on both sides of the road are often disturbed by noise, especially near the main urban roads. High-intensity traffic noise has a significant impact on the quality of life of residents. Noise pollution not only affects the physical health of residents, but also interferes with normal life and work order. Therefore, how to effectively reduce the spread of traffic noise and improve the living environment of residential areas has become a technical problem to be solved. In response to this problem, this utility model proposes an urban road traffic noise control component, which aims to provide an efficient and convenient solution through innovative structural design and effective noise reduction technology.

[0003] Currently, the devices used for noise control on the market mainly include sound-absorbing walls, sound insulation panels, and sound barriers. These devices usually reduce the transmission of noise through physical isolation. Common design principles include reducing the reflection and transmission of sound energy through the action of sound-absorbing materials, such as using sound-absorbing materials like rock wool and glass wool to absorb noise.

[0004] While existing noise control components can isolate and absorb traffic noise to a certain extent, they have significant shortcomings in installation and maintenance. In particular, when a large number of noise control panels need to be installed, the installation process is complex and inefficient, requiring a lot of manpower and time. In addition, some noise control structures lack effective sound guidance and sound insulation technologies, resulting in less than ideal noise isolation effects, especially in the control of high-intensity traffic noise. Therefore, a new urban road traffic noise control component is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an urban road traffic noise control component, which aims to improve the problem that traditional equipment is difficult to absorb noise generated on urban roads, thus affecting the poor living environment of residential areas on both sides of the road.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a noise control component for urban road traffic, comprising a vacuum plate one and a vacuum plate two, wherein a vacuum groove is provided inside the vacuum plate one, and a noise reduction component is provided on the outer wall of the vacuum plate one, the noise reduction component being used to absorb the transmitted noise;

[0007] The noise reduction component includes a sound-absorbing cotton frame and a metal plate. The bottom of the sound-absorbing cotton frame is fixedly connected to the top of the first vacuum plate. Rock wool is fixedly connected to the top of the first vacuum plate. The bottom of the metal plate is fixedly connected to the top of the rock wool. Holes are opened inside the metal plate. Nuts are provided on the outer wall of the metal plate. Threaded posts are fixedly connected to the side wall of the nuts. The threaded posts are all threadedly connected to the metal plate, rock wool, and the first vacuum plate. Assembly components are provided on the outer walls of the first and second vacuum plates. The assembly components are used to assemble the noise reduction panels.

[0008] As a further description of the above technical solution: the assembly component includes a sliding frame one and a sliding frame two, one side wall of the sliding frame is fixedly connected to the outer wall of the vacuum plate one, and the outer wall of the sliding frame two is fixedly connected to the outer wall of the vacuum plate two;

[0009] As a further description of the above technical solution: a rack plate is slidably connected inside the vacuum plate two, and a pull ring is fixedly connected to one end of the rack plate;

[0010] As a further description of the above technical solution: the other end of the rack plate is slidably connected inside the sliding frame, and a pressure block is slidably connected inside the sliding frame;

[0011] As a further description of the above technical solution: a connecting block is fixedly connected to the bottom of the first pressure block, and a second pressure block is slidably connected inside the first sliding frame;

[0012] As a further description of the above technical solution: a connecting block two is fixedly connected to the bottom of the pressure block two, and the connecting block two is slidably connected inside the sliding frame one;

[0013] As a further description of the above technical solution: a spring is provided inside the sliding frame, one end of the spring is fixedly connected to one side wall of the pressure block, and the other end of the spring is fixedly connected to the other side wall of the pressure block.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, noise is gathered by the sound-absorbing cotton frame, and then guided into the rock wool for absorption through the holes opened inside the metal plate. Subsequently, the noise is isolated by the vacuum plate, thereby achieving the effect of weakening and isolating traffic noise. This solves the problem that noise generated on urban roads affects the poor living environment of residential areas on both sides of the road, and improves the noise reduction strength of the noise control component.

[0016] 2. In this utility model, by squeezing and releasing the pressure block one and pressure block two, the pressure block one and pressure block two squeeze the spring, causing the spring to contract. Releasing the pressure block one and pressure block two causes the spring to rebound. Then, the rack plate is moved by the pull ring, thereby achieving the effect of rapid disassembly and assembly of the vacuum plate module. This solves the problem of cumbersome installation steps and low installation efficiency when installing a large number of vacuum plates, and improves the installation efficiency of noise control components.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Reference Figure 1 - Figure 3The present invention provides an embodiment of a noise control component for urban road traffic, comprising a vacuum plate 1 and a vacuum plate 9. The vacuum plate 1 has a vacuum groove 4 inside, and a noise reduction component is provided on the outer wall of the vacuum plate 1. The noise reduction component is used to absorb the transmitted noise.

[0026] The noise reduction component includes a sound-absorbing cotton frame 2 and a metal plate 3. The bottom of the sound-absorbing cotton frame 2 is fixedly connected to the top of the vacuum plate 1. Rock wool 5 is fixedly connected to the top of the vacuum plate 1. The bottom of the metal plate 3 is fixedly connected to the top of the rock wool 5. Holes 6 are opened inside the metal plate 3. Nuts 7 are provided on the outer wall of the metal plate 3. Threaded posts 8 are fixedly connected to the side wall of the nut 7. The threaded posts 8 are all threadedly connected to the metal plate 3, rock wool 5, and vacuum plate 1. Assembly components are provided on the outer walls of vacuum plate 1 and vacuum plate 2. The assembly components are used to combine the noise reduction materials. The assembly components ensure the stable fixation of the noise reduction materials through their connection function, thereby enhancing the overall sound insulation effect of the component and preventing the noise reduction effect from decreasing due to loose parts during use. The design of the assembly components allows the noise reduction materials to be adjusted and combined as needed, providing a flexible installation method, further improving the adaptability and practicality of the component, ensuring stability and efficiency after long-term use. The overall structure can effectively reduce noise pollution caused by urban road traffic and achieve ideal noise control effect.

[0027] Specifically, when vehicles pass by on city roads, the noise generated spreads to both sides of the road. This noise gradually increases with the speed and frequency of the vehicles, impacting the surrounding environment, especially the residential areas on both sides of the road, where noise pollution is particularly severe. When the noise reaches the noise control component, it first propagates to the area around the sound-absorbing cotton frame 2. The sound-absorbing cotton frame 2 absorbs and mitigates some of the noise energy through its internal sound-absorbing material. Subsequently, the noise is conducted through the sound-absorbing cotton frame 2 and enters the surface of the metal plate 3. The special design of the metal plate 3 allows it to effectively contact the noise and guides the noise inward through the array of holes 6 inside. When the noise passes through the array of holes 6, it is absorbed and mitigated by the sound-absorbing cotton frame 2. Through the guiding effect of the perforation 6, the noise is transported into the interior of the rock wool 5. The rock wool 5 has excellent sound absorption performance. Through its dense fiber structure, it can further absorb the high-frequency components in the noise and reduce the propagation energy of the noise. As the noise continuously attenuates inside the rock wool 5, the noise that is not completely eliminated is finally effectively blocked by the insulation layer of the vacuum plate 1, preventing the noise from continuing to spread to both sides of the urban road. The entire noise control component, through the effective combination of multiple layers of materials and structures, can effectively weaken the intensity of traffic noise and isolate it on one side of the road, thereby significantly improving the living environment of residents on both sides of the road, enhancing the living comfort of the urban area, and reducing the negative impact of noise on people's daily lives.

[0028] Reference Figure 4 and Figure 5The assembly includes a sliding frame 10 and a sliding frame 2 11. The side wall of sliding frame 10 is fixedly connected to the outer wall of vacuum plate 1. The outer wall of sliding frame 2 11 is fixedly connected to the outer wall of vacuum plate 2 9. A rack plate 13 is slidably connected inside vacuum plate 2 9. A pull ring 12 is fixedly connected to one end of rack plate 13, and the other end of rack plate 13 is slidably connected inside sliding frame 10. A pressure block 14 is slidably connected inside sliding frame 10. A connecting block 17 is fixedly connected to the bottom of pressure block 14. A pressure block 2 15 is slidably connected inside sliding frame 10. A connecting block 2 18 is fixedly connected to the bottom of pressure block 2 15. The connecting block 2 18 is slidably connected inside sliding frame 10. A spring is installed inside sliding frame 10. 16. One end of spring 16 is fixedly connected to the side wall of pressure block 14, and the other end of spring 16 is fixedly connected to the side wall of pressure block 2 15. The combination design of the above components makes the assembly assembly have good adjustability and flexibility, and can adjust the tightness of the noise reduction plate according to actual needs to ensure the stability of the structure. At the same time, spring 16 provides appropriate pressure, so that pressure block 14 and pressure block 2 15 can move smoothly in the sliding frame, avoiding loosening or instability of the assembly during use. The cooperation of pull ring 12 and rack plate 13 ensures precise docking during assembly. The overall structure enhances the noise reduction effect and improves the service life of the assembly, ensuring its reliability and efficiency in long-term use.

[0029] Specifically, when it is necessary to dismantle and separate vacuum plate 1 and vacuum plate 9, firstly, by squeezing pressure blocks 14 and 15, they can slide smoothly inside sliding frame 10. As these two pressure blocks slide, the internal spring 16 is compressed and contracts, storing elastic potential energy. When released, it can generate a certain reaction force. The compression process of spring 16 makes the sliding of pressure blocks 14 and 15 more stable. During the movement of these two pressure blocks, connecting blocks 17 and 18 are also driven and... The components slide together within the sliding frame 10. At this time, connecting block 17 and connecting block 2 18 separate from the rack plate 13, and the rack plate 13 detaches from its original position. Next, by pulling the pull ring 12, the movement of the pull ring 12 will drag the rack plate 13 to slide smoothly inside the sliding frame 2 11, thus completing the disassembly and separation of the noise control component. Throughout the process, the various components work together in a precise and coordinated manner, making the disassembly and assembly operation more efficient and convenient, achieving the intended purpose. The entire disassembly and separation operation is not only simple but also safe and reliable, ensuring that no component is damaged during operation.

[0030] Working Principle: When using noise control components, noise generated by vehicles passing through urban roads propagates and diffuses to both sides of the road. When the noise reaches the vicinity of the noise control components, it first propagates to the area around the sound-absorbing cotton frame 2, and then is conducted through the sound-absorbing cotton frame 2 to the surface of the metal plate 3. The metal plate 3 has an array of holes 6 inside. As the noise passes through the array of holes 6, it is guided by the holes 6 and transported into the rock wool 5. The rock wool 5 then absorbs and attenuates the noise. Finally, the remaining noise is isolated to one side of the urban road by the vacuum plate 1, which acts as a final layer of insulation. Through the cooperation of the above components, the purpose of reducing and isolating traffic noise is achieved, improving the living conditions of residents on both sides of the road. In a live environment, when it is necessary to disassemble and separate vacuum plate 1 and vacuum plate 9, firstly, by squeezing pressure block 14 and pressure block 2 15, pressure block 14 and pressure block 2 15 are made to slide inside sliding frame 10. When pressure block 14 and pressure block 2 15 slide, they will squeeze the internal spring 16. The spring 16 is squeezed and compressed and stores elastic force. While pressure block 14 and pressure block 2 15 are moving, connecting block 17 and connecting block 2 18 are driven to slide inside sliding frame 10. At this time, connecting block 17 and connecting block 2 18 are separated from rack plate 13. Then, by pulling pull ring 12, pull ring 12 moves and drags rack plate 13 to slide inside sliding frame 2 11. Through the coordinated linkage of the above structures, the purpose of disassembling and separating the noise control components is achieved.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
