Description

Technical Field

[0001] This invention belongs to the field of sound insulation equipment technology, specifically relating to a modular sound insulation screen and sound insulation system. Background Technology

[0002] Currently, major cities are undertaking road construction and improvement projects. The resulting noise pollution significantly impacts people's study, work, and rest. Noise pollution and its harmful effects are increasingly attracting attention and have been listed as one of the world's four major environmental pollutants. Among various noise control measures, sound barriers are a primary component of noise control engineering. Sound barriers are widely used along highways, railway lines, both sides of viaducts, around airports, at industrial plant boundaries, and at equipment operation sites. Through sound wave reflection and absorption, they block noise from propagating to sensitive areas requiring protection (such as residential areas, schools, and hospitals).

[0003] Chinese patent document CN222923637U discloses a sound barrier for roads and bridges, belonging to the technical field of road and bridge sound insulation facilities. It addresses the problem that existing sound barriers are easily subjected to significant impact from strong winds blowing directly on them. The design includes a sound barrier body, a sound-insulating top plate, sound-insulating blocking components, a windbreak, a drive fan, a sound-insulating cleaning mechanism, and a sound-insulating stabilizing mechanism. The sound-insulating top plate is fixedly connected to the top of the sound barrier body. The sound-insulating blocking components are fixedly connected to the front of the sound-insulating top plate. The windbreak is rotatably connected to the upper inner side of the sound barrier body. Cleaning limiting grooves are respectively formed at the upper and lower inner ends of the sound barrier body. The drive fan is rotatably connected to the upper rear end of the sound barrier body. The sound-insulating cleaning mechanism is located inside the sound barrier body. The sound-insulating stabilizing mechanism is located at the upper rear end of the sound barrier body, reducing the impact of strong winds on the sound barrier and ensuring the stability of the sound barrier installation.

[0004] Most existing sound barriers are fixed structures. Once installed, their location and coverage area remain unchanged, which has the following main drawbacks: insufficient flexibility, as existing fixed sound barriers are difficult to adjust according to the addition or reduction of noise equipment in the site and the actual acoustic environment; poor versatility, as the main frame and sound insulation modules of existing fixed sound barriers cannot be interchanged in real time, and they cannot be used after changing sites, resulting in waste of materials and costs; and high usage requirements, as existing fixed sound barriers require a foundation or hardened bottom surface at the installation location, and generally cannot be used on unhardened ground, increasing the construction process. Summary of the Invention

[0005] The purpose of this invention is to provide a modular sound barrier and sound insulation system to solve the above-mentioned problems existing in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a modular sound barrier, comprising a mounting frame, an outer panel, and a sound-absorbing perforated panel; the bottom of the mounting frame is provided with a support bracket, on which a counterweight sandbox is mounted; both the outer panel and the sound-absorbing perforated panel are mounted on the mounting frame, with the outer panel located outside the sound-absorbing perforated panel; the two side walls of the mounting frame are respectively provided with a first splicing structure and a second splicing structure, which are matched with each other; the mounting frame is equipped with a fixing structure for fixing two spliced ​​modular sound barriers together.

Detailed Implementation

[0024] like Figures 1-5 As shown, this embodiment provides a modular sound barrier, including a mounting frame 1, an outer panel 2, and a sound-absorbing perforated panel 3. The bottom of the mounting frame 1 is equipped with a foldable support leg, which is foldable to facilitate the transportation of the sound barrier. A counterweight sandbox 4 is installed on the support leg. When in use, the counterweight sandbox 4 is filled with sand and connected to the support leg, which can improve the overall stability of the sound barrier and enhance its overall wind resistance.

[0025] like Figure 3 As shown, both the outer panel 2 and the sound-absorbing perforated panel 3 are mounted on the mounting frame 1, with the outer panel 2 located outside the sound-absorbing perforated panel 3. Sound-absorbing medium is filled between the outer panel 2 and the sound-absorbing perforated panel 3. The outer panel 2 faces the outer side of the highway, railway line, or viaduct, while the sound-absorbing perforated panel 3 faces the inner side of the highway, railway line, or viaduct. By filling the space between the outer panel 2 and the sound-absorbing perforated panel 3 with sound-absorbing medium, the sound insulation effect of the sound barrier is increased.

[0026] The two side walls of the mounting frame 1 are respectively provided with a first splicing structure and a second splicing structure, which are matched with each other. The mounting frame 1 is equipped with a fixing structure for fixing two spliced ​​modular sound barriers together. The sound barrier of the present invention adopts a modular design, and the sound barriers are quickly assembled by splicing. Adjacent sound barriers are fixed together by the fixing structure. Its structure is simple, easy to install, and conducive to improving construction efficiency.

[0027] like Figure 5 As shown, in this embodiment, the first splicing structure includes a splicing protrusion 5, and the second splicing structure includes a splicing slot 6. The splicing slot 6 and the splicing protrusion 5 are matched with each other. During the splicing of the soundproof screens, two soundproof screens are placed side by side, and the splicing protrusion 5 of one soundproof screen is inserted into the splicing slot 6 of the other soundproof screen. Then, a fixing structure is used to fix the two soundproof screens, completing the assembly of the soundproof screens.

[0028] Specifically, the fixing structure includes a connector and two connecting ear plates 7. The two connecting ear plates 7 are respectively mounted on the mounting frames 1 of two adjacent modular soundproof barriers, and the connector is connected to the two connecting ear plates 7. Preferably, the connector includes a buckle 8 and a pin 9. The buckle 8 is located between the two connecting ear plates 7, and the buckle 8 is fixed to the connecting ear plate 7 by the pin 9. Each soundproof barrier has connecting ear plates 7 on both sides, which facilitates the connection and fixing of this soundproof barrier to the soundproof barriers on both sides.

[0029] like Figure 2 and Figure 3 As shown, in one specific embodiment, the support frame includes a tripod support frame 10, a connector 11 at the bottom of the mounting frame 1, and a locking pin 12 between the tripod support frame 10 and the connector 11. The tripod support frame 10 is foldable for easy overall transportation of the soundproof barrier. The bottom of the tripod support frame 10 is equipped with adjustable support legs. Figure 4 As shown, specifically, the adjustable outrigger assembly includes a support screw 13, an upper adjusting nut 14, a lower adjusting nut 15, and a support mat 16. The tripod support frame 10 has a through hole adapted to the support screw 13. The upper adjusting nut 14 and the lower adjusting nut 15 are both threadedly connected to the support screw 13, and the upper adjusting nut 14 and the lower adjusting nut 15 are located above and below the through hole, respectively. The support mat 16 is located at the bottom end of the support screw 13. Each soundproof barrier is equipped with four tripod support frames 10. The balance of the tripod support frame 10 can be adjusted by the adjustable outrigger assembly to meet the needs of different terrains.

[0030] The counterweight sand box 4 is equipped with mounting holes and locking bolts, which are connected to the tripod support frame 10. In practical applications, one end of the locking bolt is passed through the tripod support frame 10 and the mounting hole and then connected to a nut, thereby connecting the counterweight sand box 4 to the tripod support frame 10 and increasing the stability of the sound barrier.

[0031] like Figure 1 As shown, in this embodiment, the top of the mounting frame 1 is provided with an inclined sound-absorbing baffle 17. The two ends of the sound-absorbing baffle 17 are respectively provided with a first overlapping sealing portion 18 and a second overlapping sealing portion 19, which match each other. The sound-absorbing baffle 17 is inclined towards the inner side of the highway, railway line, or overpass. When the sound barriers are spliced, the first overlapping sealing portion 18 of the previous sound barrier overlaps with the second overlapping sealing portion 19 of the subsequent sound barrier, improving the sound insulation effect.

[0032] The sound-absorbing perforated panel 3 has a thickness of 1.5mm to 10mm, and the outer panel 2 has a thickness of 0.6mm to 6mm. The sound-absorbing medium is glass wool and alkali-free fiberglass cloth. Thicker panels can be used in the sound barrier for specific equipment locations, providing better protection.

[0033] This embodiment also provides a sound insulation system, including at least two of the above-mentioned modular sound insulation screens, with adjacent modular sound insulation screens spliced ​​together by a first splicing structure and a second splicing structure, and adjacent modular sound insulation screens fixed together by a fixing structure.

[0034] This sound insulation system is a highly efficient and easily movable detachable sound insulation device. It uses multiple detachable modular sound insulation screens, which are composed of multiple sound insulation screen modules connected in sequence. The modules are quickly connected to each other by connecting ear plates 7, buckles 8 and pins 9.

[0035] Each sound barrier includes a mounting frame 1, an outer panel 2, and a sound-absorbing perforated panel 3. The sound-absorbing perforated panel 3 is located inside the outer panel 2. A connector 11 for connecting a tripod support 10 is fixed to the lower part of the mounting frame 1. The tripod support 10 and the connector 11 are secured by locking pins 12. Matching splicing protrusions 5 and splicing grooves 6 are machined on the side walls at both ends of the mounting frame 1. A sound-absorbing baffle 17 is inclinedly installed on the top of the mounting frame 1, and sound-absorbing holes are machined on the inner side of the baffle 17. A counterweight sandbox 4 is connected to the tripod support 10 at the bottom of the sound barrier. During use, the counterweight sandbox 4 is filled with sand and then connected to the tripod support 10, which improves the overall stability of the sound barrier and enhances its wind resistance. One of the sound barriers in the soundproofing system has an inspection door located in a suitable position for easy access and maintenance.

[0036] Compared with existing fixed sound barriers, the present invention has the following outstanding advantages: 1. On-demand and efficient noise reduction: It can make precise and dynamic response deployment according to the real-time changes of noise sources (location, intensity, spectrum), significantly improving the noise reduction effect and stability of the target protection area, and avoiding the problems of "over-protection" or "under-protection".

[0037] 2. Optimized resource utilization: Deploy high barriers (height or coverage) only when needed and only in key locations, significantly saving sound insulation materials, reducing overall construction and installation costs, and allowing some areas to remain low or open during low-noise periods.

[0038] 3. Enhanced spatial adaptability: It can flexibly avoid or temporarily open passages, facilitating the space requirements for large equipment maintenance, emergency rescue operations, and construction operations, and is especially suitable for environments with limited space or multiple functions.

[0039] 4. Modular design: Each sound barrier adopts a standardized modular design, which facilitates production, installation, replacement and maintenance.
