Abstract

This invention relates to the field of sound barrier unit panel technology, specifically to a foldable sound barrier unit panel device for preventing noise pollution. It includes a support body with symmetrical sound insulation panels rotatably connected to both sides. Each sound insulation panel has a limiting groove at its top and is filled with sound-absorbing cotton to block noise. A moving component is located at the end of the support body, used to unfold the placed sound insulation panels. Simultaneously, when the sound insulation panels are fully unfolded, the end of the moving component extends outside the support body to warn pedestrians. This invention moves the support body to the construction area, causing a rack to move under the force of a reset component. The rack's movement drives a driven gear to rotate, causing the folded sound insulation panels below the driven gear to automatically rotate in the opposite direction. This rotates the sound insulation panels to a horizontal position, increasing the noise reduction area while reducing the assembly strength of the sound insulation panels and improving construction efficiency.

Description

Technical Field

[0001] This invention relates to the field of sound barrier unit panel technology, and more specifically, to a sound barrier unit panel device based on a foldable design for preventing noise pollution. Background Technology

[0002] With social progress and people's increasing demands for living environment, some old residential areas in various regions need to undergo housing reform to improve the quality of life of residents in these areas. During the renovation process in old urban residential areas, noise pollution is usually generated. In order to reduce noise pollution during construction, sound insulation boards are often used to isolate noise from the construction sections.

[0003] There are many existing technologies for sound barrier unit panels, such as:

[0004] Chinese Patent Publication No. CN103015338A discloses a sound barrier unit panel device for preventing noise pollution, belonging to the environmental protection field. It consists of a sound-absorbing panel, sound-absorbing material, and a sound-insulating panel, with the sound-absorbing material placed within the cavity formed between the sound-absorbing panel and the sound-insulating panel. This invention allows sound waves to enter the porous fiber sound-absorbing material through sound-absorbing holes on the sound-absorbing panel. The porous fiber sound-absorbing material has numerous tiny interconnected pores inside, allowing sound waves to penetrate deep into the material along these pores, interacting with the material through friction and converting sound energy into heat energy. The sound waves passing through the porous fiber sound-absorbing material then impact the surface of the sound-insulating material and are reflected back to the porous fiber sound-absorbing material, undergoing secondary friction and again converting sound energy into heat energy, thereby achieving the sound insulation effect.

[0005] When using existing sound barrier unit panels, due to the long construction sections, it is necessary to temporarily splice the sound barrier unit panels. This splicing process increases the construction time. Moreover, after the construction of the section is completed, the spliced ​​sound barrier unit panels need to be disassembled, which affects the construction efficiency. At the end of the construction section, when there is not enough remaining length to place a whole sound barrier unit panel, large gaps appear in the sound barrier wall composed of sound barrier unit panels, which affects the noise reduction effect.

[0006] In view of this, we propose a foldable sound barrier unit panel device for preventing noise pollution. Summary of the Invention

[0007] The purpose of this invention is to provide a foldable sound barrier unit panel device for preventing noise pollution, so as to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, the present invention provides a foldable sound barrier unit panel device for preventing noise pollution, comprising a support body, the top of which is hollow, a cylinder being provided at the top of the support body, symmetrical sound insulation panels being rotatably connected to both sides of the support body, a limiting groove being provided at the top of the sound insulation panel, sound insulation cotton being filled inside the sound insulation panel for blocking noise, a moving component being provided at the end of the support body, the moving component being used to unfold the placed sound insulation panel, and simultaneously, when the sound insulation panel is fully unfolded, the end of the moving component extends to the outside of the support body to warn pedestrians, and a folding fixing component being provided at the end of the moving component, the folding fixing component being used to fix the folded sound insulation panel.

[0009] As a further improvement to this technical solution, the sound insulation plate passes through the bottom of the support body and is provided with a driven gear at the end. When the moving component moves, it drives the driven gear to rotate, causing the folded sound insulation plate to rotate in the opposite direction until it is horizontal.

[0010] As a further improvement to this technical solution, the moving component includes a rack penetrating the end of the support body. The rack has a left block and a right block at its two ends. A reset component is provided between the left block and the support body. Without external force, the reset component pulls the left block to the right block. The right block has a hollow structure inside and symmetrical warning lights on both sides. The warning lights are used to warn pedestrians. A folding fixing component is provided inside the right block.

[0011] As a further improvement to this technical solution, the reset assembly includes a cylindrical tube disposed at the end of the support body, a sliding rod slidably connected to the inner wall of the cylindrical tube, one end of the sliding rod being fixed to the inner side of the left side block, and a first elastic element being fixedly disposed inside the cylindrical tube, the other end of the first elastic element being fixed to the bottom of the sliding rod.

[0012] As a further improvement to this technical solution, a cylinder is provided at the top of the support body, and the piston rod at the end of the cylinder pushes the left block, causing the sound insulation panels on both sides of the support body to rotate and fold in the vertical direction at the same time.

[0013] As a further improvement to this technical solution, a limiting groove is started at the top of the rack, and the rack moves to fit against the limiting block provided at the top of the support.

[0014] As a further improvement to this technical solution, the folding fixing component includes a fixing block that slides on the inner wall of the right side block. A second elastic element is provided between the fixing block and the right side block. When the fixing block moves to the limiting slot, it is engaged and fixed with the limiting slot by the force of the second elastic element.

[0015] As a further improvement to this technical solution, the two sides of the fixing block are sloped. When the piston rod at the end of the cylinder pushes the left block to rotate the sound insulation plate, the side of the sound insulation plate squeezes the two sides of the fixing block, causing the fixing block to slide on the inner wall of the right block.

[0016] As a further improvement to this technical solution, the top of the fixing block is provided with a screw rod, and the surface of the screw rod is provided with threads. The fixing block that is locked in the inner wall of the limiting groove is fixed by rotating the screw rod.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] 1. In this foldable sound barrier unit panel device for preventing noise pollution, by moving the support body to the construction area, the rack moves under the force of the reset component. When the rack moves, it drives the driven gear to rotate, causing the folded sound insulation panel below the driven gear to rotate automatically in the opposite direction. This allows the sound insulation panels to rotate to a horizontal position, increasing the noise reduction area, while reducing the assembly strength of the sound insulation panels and improving construction efficiency.

[0019] 2. In this foldable noise barrier unit panel device for preventing noise pollution, a cylinder is provided at the top of the support body. The piston rod at the end of the cylinder pushes the left block, causing the sound insulation panels on both sides of the support body to rotate and fold vertically at the same time. The piston rod at the end of the cylinder pushes the left block, causing the left block to drive the rack to move away from the right block. When the rack moves, it drives the driven gear to rotate in the opposite direction, thereby causing the sound insulation panels on both sides of the support body to rotate to a position perpendicular to the horizontal, so that the position between the sound insulation panels is folded, thereby reducing the footprint of the device and making it easier to store the device.

[0020] 3. In this foldable sound barrier unit panel device for preventing noise pollution, when the placement space of the device is relatively narrow, the position of the left block is pushed by adjusting the piston rod at the end of the cylinder so that the sound insulation panels are at the required angle. This allows the unfolded sound insulation panels to fill the gaps in the noise reduction area, thus solving the problem of narrow placement space and improving the practicality of the device.

[0034] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] With social progress and people's increasing demands for living environments, some old residential areas in various regions need to undergo housing reform to improve the quality of life for residents. However, the existing sound barrier unit panels require temporary splicing during construction due to the long construction sections. This splicing process increases construction time. Furthermore, after the construction is completed, the spliced ​​sound barrier unit panels need to be disassembled, affecting construction efficiency. Additionally, at the ends of the construction sections, when there is insufficient remaining length to place a complete sound barrier unit panel, large gaps appear in the soundproof wall composed of the unit panels, affecting the noise reduction effect.

[0036] The purpose of this embodiment is to provide a foldable sound barrier unit panel device for preventing noise pollution. (See attached document.) Figures 1-8As shown, the device includes a support body 100 with a hollow top. A cylinder 101 is located on the top of the support body 100. Symmetrical sound-insulating panels 200 are rotatably connected to both sides of the support body 100. Each sound-insulating panel 200 has a limiting groove 201 on its top. Sound-insulating cotton is filled inside the sound-insulating panels 200 to block noise. (See reference...) Figure 1 and Figure 3 As shown, the support body 100 has a moving component 300 at its end. The moving component 300 is used to unfold the placed sound insulation panel 200. Simultaneously, when the sound insulation panel 200 is fully unfolded, the end of the moving component 300 extends outside the support body 100 to warn pedestrians. By moving the support body 100 to the construction area, the rack 301 moves under the force of the reset component 302. The movement of the rack 301 drives the driven gear 202 to rotate, causing the folded sound insulation panel 200 below the driven gear 202 to automatically rotate in the opposite direction. This allows the sound insulation panels 200 to rotate to a horizontal position, increasing the noise reduction area, reducing the assembly strength of the sound insulation panels 200, and improving construction efficiency. (See reference...) Figure 2 and Figure 3 As shown, the end of the movable component 300 is provided with a folding fixing component 400, which is used to fix the folded sound insulation panel 200.

[0037] By providing a cylinder 101 at the top of the support body 100, the piston rod at the end of the cylinder 101 pushes the left block 303, causing the sound insulation panels 200 on both sides of the support body 100 to rotate and fold vertically at the same time. The piston rod at the end of the cylinder 101 pushes the left block 303, causing the left block 303 to drive the rack 301 to move away from the right block 305. When the rack 301 moves, it drives the driven gear 202 to rotate in the opposite direction, thereby causing the sound insulation panels 200 on both sides of the support body 100 to rotate to a position perpendicular to the horizontal, so that the position between the sound insulation panels 200 is folded, thereby reducing the footprint of the device and making it easier to store the device.

[0038] Considering that construction noise during community environmental improvement projects can easily affect residents, sound insulation panels (200mm) are commonly used to isolate noise in order to reduce noise pollution. However, the existing sound insulation panels require temporary assembly by workers to increase the noise insulation area, which is quite troublesome. (See reference...) Figure 2 and Figure 5 As shown, the sound insulation panel 200 passes through the bottom of the support body 100 and has a driven gear 202 at its end. When the moving component 300 moves, it drives the driven gear 202 to rotate, causing the folded sound insulation panel 200 to rotate in the opposite direction until it is horizontal. In order to quickly assemble the sound insulation panel 200, the moving component 300 moves and drives the driven gear 202 to rotate, thereby rotating the sound insulation panel 200 to a horizontal position to increase the noise reduction area and reduce the assembly strength of the sound insulation panel 200, thus reducing the labor intensity of the workers.

[0039] For quick deployment of the folded sound insulation panel 200, please refer to... Figure 6 and Figure 7 As shown, the movable component 300 includes a rack 301 penetrating the end of the support body 100. A left block 303 and a right block 305 are respectively located at both ends of the rack 301. A reset component 302 is provided between the left block 303 and the support body 100. Without external force, the reset component 302 pulls the left block 303 towards the right block 305. The right block 305 has a hollow interior and symmetrical warning lights 306 on both sides. The warning lights 306 are used to warn pedestrians. A folding fixing component 400 is located inside the right block 305. During construction, the support body 100 is placed in the location requiring noise reduction. The reset component 302 includes a column 3021 located at the end of the support body 100. A sliding rod 3022 is slidably connected to the inner wall of the column 3021. 2 One end is fixed to the inner side of the left block 303. The column 3021 and the inside are fixed with a first elastic element 3023. The other end of the first elastic element 3023 is fixed to the bottom of the slide rod 3022. In the natural state, the slide rod 3022 slides on the inner wall of the column 3021 under the force of the first elastic element 3023, so that the left block 303 drives the rack 301 to move horizontally. The driven gears 202 on both sides of the rack 301 mesh and rotate, so that the sound insulation panels 200 rotate relative to each other and unfold, quickly reducing noise in the construction area. At the same time as the sound insulation panels 200 unfold, the right block 305 moves to the end away from the support body 100. The warning light 306 at the end of the right block 305 is activated to warn pedestrians and prevent pedestrians from entering the construction area, thus avoiding safety hazards.

[0040] When construction is completed, to facilitate the storage of the device and reduce its footprint, please refer to [reference needed]. Figure 6 As shown, a cylinder 101 is provided on the top of the support body 100. The piston rod at the end of the cylinder 101 pushes the left block 303, causing the sound insulation panels 200 on both sides of the support body 100 to rotate and fold vertically at the same time. The piston rod at the end of the cylinder 101 pushes the left block 303, causing the left block 303 to drive the rack 301 to move away from the right block 305. When the rack 301 moves, it drives the driven gear 202 to rotate in the opposite direction, thereby causing the sound insulation panels 200 on both sides of the support body 100 to rotate to a position perpendicular to the horizontal, so that the sound insulation panels 200 are folded together, thereby reducing the footprint of the device and making it easier to store the device, thus improving the practicality of the device. At the same time, when the place where the device is placed is relatively narrow, by adjusting the position of the left block 303 pushed by the piston rod at the end of the cylinder 101, the sound insulation panels 200 are made to form the required angle, which solves the problem of narrow placement space and improves the practicality of the device.

[0041] To prevent the rack 301 from shifting position and getting stuck on the inner wall of the support 100 during movement, a limiting groove 304 is provided at the top of the rack 301. When the rack 301 moves, it fits against the limiting block provided at the top of the support 100. During the movement of the rack 301, the limiting groove 304 provided at the top of the rack 301 slides against the bottom of the limiting block, keeping the rack 301 horizontal during movement, thereby ensuring the efficiency of the device when unfolding and folding during use.

[0042] When the device needs to be folded and stored after construction, to prevent it from automatically unfolding and affecting the folding and storage efficiency, please refer to [the relevant documentation / reference]. Figure 4 and Figure 8 As shown, the folding fixing assembly 400 includes a fixing block 401 that slides on the inner wall of the right block 305. A second elastic element 402 is provided between the fixing block 401 and the right block 305. When the fixing block 401 moves to the limiting slot 201, it is engaged and fixed with the limiting slot 201 by the force of the second elastic element 402. The two sides of the fixing block 401 are sloped. When the piston rod at the end of the cylinder 101 pushes the left block 303 to rotate the sound insulation plate 200, the side of the sound insulation plate 200 presses the two sides of the fixing block 401, causing the fixing block 401 to slide on the inner wall of the right block 305. When the piston rod at the end of the cylinder 101 pushes the end of the left block 303, the rack 301 drives the driven gears 202 on both sides to rotate in the opposite direction, thereby causing the sound insulation plates 200 provided on both sides of the support body 100 to rotate to As the sound insulation panel 200 rotates perpendicular to the horizontal direction, its outer edge first contacts the side of the fixing block 401. Since the two sides of the fixing block 401 are sloped, the outer edge of the limiting groove 201 gradually presses against the bottom of the fixing block 401, causing the fixing block 401 to slide on the top of the sound insulation panel 200. When the sound insulation panel 200 rotates to be perpendicular to the horizontal direction, the fixing block 401 moves downward under the force of the second elastic element 402. At this time, the fixing block 401 is located above the limiting groove 201, so that the fixing block 401 is engaged with the inner wall of the limiting groove 201, thus simultaneously fixing the folded sound insulation panels 200 and preventing the device from automatically unfolding under the force of the reset component 302 after folding, thereby improving the folding efficiency of the device.

[0043] To improve the stability of the device during folding and ensure structural stability during use, please refer to... Figure 4As shown, the top of the fixing block 401 is provided with a screw 403, and the surface of the screw 403 is provided with threads. By rotating the screw 403, the fixing block 401 is fixed to the inner wall of the limiting slot 201. When the fixing block 401 is fixed to the inner wall of the limiting slot 201, in order to prevent it from popping out of the inner wall of the limiting slot 201, the screw 403 is rotated to press the fixing block 401, thereby improving the stability of the fixing block 401 in the limiting slot 201. When it is necessary to release the folded state of the device, the screw 403 is rotated in the opposite direction, thereby moving the fixing block 401 away from the folding fixing component 400, so that the sound insulation panel 200 can be quickly unfolded to reduce external noise.

[0044] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention.
