Description

Technical Field

[0001] The present invention relates to the technical field of sound barrier unit panels, and in particular to a foldable sound barrier unit panel device for preventing and controlling noise pollution. Background Art

[0002] With the progress of society and people's increasing demands for living environment, some old communities in various regions need to undergo housing reforms to improve the quality of life of people living in old communities. Noise pollution is usually generated during the renovation of old residential areas. In order to reduce the noise pollution and other problems generated during construction, sound insulation panels are used to isolate the construction section from noise.

[0003] There are many existing technologies for sound barrier unit panels, such as: Chinese patent publication number CN103015338A discloses a sound barrier unit panel device for preventing and controlling noise pollution, which belongs to the field of environmental protection. It is composed of a sound absorbing board, a sound absorbing material, and a sound insulating board. The sound absorbing material is arranged in the cavity formed between the sound absorbing board and the sound insulating board. The present invention allows sound waves to enter the porous fiber sound absorbing material through the sound absorbing holes on the sound absorbing board. There are a large number of tiny interconnected pores inside the fiber porous sound absorbing material. The sound waves can penetrate into the material along these pores, rub against the material, and convert the sound energy into heat energy. The sound waves passing through the porous fiber sound absorbing material hit the surface of the sound insulating material and then reflect back to the porous fiber sound absorbing material, rub against the material for the second time, and convert the sound energy into heat energy again, thereby achieving the effect of sound insulation.

[0004] When the existing sound barrier unit panel device is in use, due to the long construction section, the sound barrier unit panel device needs to be temporarily spliced. During the splicing process, the construction time is increased. Moreover, after the road section construction is completed, the spliced ​​sound barrier unit panels need to be disassembled, affecting the construction efficiency. At the same time, at the end of the construction section, when the remaining length is not enough to place the entire sound barrier unit panel, a large gap will appear in the sound insulation wall composed of the sound barrier unit panels, affecting the noise reduction effect.

[0005] In view of this, we propose a foldable sound barrier unit panel device for preventing and controlling noise pollution. Summary of the invention

[0011] As a further improvement of the technical solution, a cylinder is provided on the top of the support body, and the piston rod at the end of the cylinder pushes the left block, so that the sound insulation boards arranged on both sides of the support body are rotated and folded in the vertical direction at the same time.

[0012] As a further improvement of the technical solution, a limiting groove is provided at the top of the rack, and when the rack moves, it fits into a limiting block provided at the top of the support body.

[0013] As a further improvement of the present technical solution, the folding and fixing assembly includes a fixing block sliding on the inner wall of the right block, and a second elastic member is provided between the fixing block and the right block. When the fixing block moves to the limiting slot, it is clamped and fixed to the limiting slot by the force of the second elastic member.

[0014] As a further improvement of the technical solution, the two sides of the fixed block are sloped.

[0018] 3. In the foldable sound barrier unit panel device for preventing and controlling noise pollution, when the location for placing 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 required angle between the sound insulation panels is set, so that the unfolded sound insulation panels can fill the vacant positions in the area where noise reduction is required, thereby solving the problem of narrow placement location and improving the practicability of the device.

DETAILED DESCRIPTION

[0021] The following will be combined with the accompanying drawings in the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] With the progress of society and people's increasing demands for living environment, some old communities in various regions need to carry out housing reform to improve the quality of life of people living in old communities. When using the existing sound barrier unit panel device, due to the long construction section, the sound barrier unit panel device needs to be temporarily spliced. During the splicing process, the construction time is increased. Moreover, after the construction of the road section is completed, the spliced ​​sound barrier unit panels need to be disassembled, affecting the construction efficiency. At the same time, at the end of the construction section, when the remaining length is not enough to place the entire sound barrier unit panel, a large gap appears in the sound insulation wall composed of the sound barrier unit panels, affecting the noise reduction effect.

[0023] The purpose of this embodiment is to provide a foldable sound barrier unit panel device for preventing and controlling noise pollution, see Figure 1-Figure 8 As shown, it includes a support body 100, the top of the support body 100 is a hollow structure, a cylinder 101 is arranged on the top of the support body 100, symmetrical sound insulation boards 200 are rotatably connected on both sides of the support body 100, and a limit slot 201 is arranged on the top of the sound insulation board 200. The sound insulation board 200 is filled with sound insulation cotton for blocking noise, see Figure 1 and Figure 3As shown, a moving assembly 300 is provided at the end of the support body 100, and the moving assembly 300 is used to unfold the sound insulation board 200 that has been placed. At the same time, when the sound insulation board 200 is unfolded, the end of the moving assembly 300 extends to the outside of the support body 100 to warn pedestrians. By moving the support body 100 to the construction area, the rack 301 is moved by the force of the reset assembly 302, and the driven gear 202 is driven to rotate when the rack 301 moves, so that the folded sound insulation board 200 under the driven gear 202 automatically rotates in the opposite direction, so that the sound insulation board 200 rotates to a horizontal state between the sound insulation boards 200 to increase the noise reduction area, while reducing the assembly strength of the sound insulation board 200, and improving the construction efficiency. Figure 2 and Figure 3 As shown, a folding and fixing assembly 400 is provided at the end of the moving assembly 300 , and the folding and fixing assembly 400 is used to fix the folded sound insulation board 200 .

[0024] By arranging a cylinder 101 on the top of the support body 100, the piston rod at the end of the cylinder 101 pushes the left block 303, so that the sound insulation boards 200 arranged on both sides of the support body 100 are rotated and folded in the vertical direction at the same time, and the piston rod at the end of the cylinder 101 pushes the left block 303, so that the left block 303 drives the rack 301 to move away from the right block 305. When moving, the rack 301 drives the driven gear 202 to rotate in the opposite direction, so that the sound insulation boards 200 on both sides of the support body 100 are rotated to a vertical position relative to the horizontal position, so that the position between the sound insulation boards 200 is folded, thereby reducing the floor space of the device and facilitating the storage of the device.

[0025] Considering that during the construction process of improving the community environment, the noise generated by the construction is likely to affect the residents of the community, in order to reduce noise pollution, the sound insulation board 200 is now mostly used to isolate the noise. However, during the use of the existing sound insulation board 200, the operator needs to temporarily assemble it to increase the noise isolation area, which is quite troublesome. Figure 2 and Figure 5 As shown, the sound insulation board 200 passes through the bottom of the support body 100 and a driven gear 202 is provided at the end thereof. When the moving assembly 300 moves, the driven gear 202 is driven to rotate, so that the folded sound insulation board 200 rotates in the opposite direction until it becomes horizontal. In order to quickly assemble the sound insulation board 200, the moving assembly 300 is moved to drive the driven gear 202 to rotate, so that the sound insulation board 200 rotates to a horizontal state to increase the noise reduction area, while reducing the assembly strength of the sound insulation board 200, thereby reducing the labor intensity of the operators.

[0026] In order to quickly unfold the folded sound insulation board 200 for use, refer to Figure 6 and Figure 7As shown, the moving assembly 300 includes a rack 301 that passes through the end of the support body 100, and the two ends of the rack 301 are respectively provided with a left block 303 and a right block 305. A reset assembly 302 is provided between the left block 303 and the support body 100. In the absence of external force, the reset assembly 302 pulls the left block 303 to move to the side of the right block 305. The right block 305 has a hollow structure inside and symmetrical warning lights 306 are provided on both sides. The warning lights 306 are used to warn pedestrians. A folding and fixing assembly 400 is provided inside the right block 305. During construction work, the support body 100 is placed at a position where noise isolation is required. The reset assembly 302 includes a column 3021 provided at the end of the support body 100. The inner wall of the column 3021 is slidably connected to a slide rod 3022. The slide rod 302 One end is fixed to the inner side of the left block 303, and a first elastic member 3023 is fixed inside the column 3021, and the other end of the first elastic member 3023 is fixed to the bottom of the slide bar 3022. In a natural state, the slide bar 3022 slides on the inner wall of the column 3021 under the action of the first elastic member 3023, so that the left block 303 drives the rack 301 to move horizontally, and the driven gears 202 on both sides of the rack 301 mesh and rotate, so that the sound insulation board 200 rotates relative to each other to unfold, and the noise in the construction area is quickly reduced. When the sound insulation board 200 is unfolded, the right block 305 moves away from the end of the support body 100, and the warning light 306 provided at the end of the right block 305 is turned on to warn pedestrians to prevent pedestrians from entering the construction area and avoid safety hazards.

[0027] When the construction is completed, in order to facilitate the storage of the device and reduce the floor space, refer to Figure 6 As shown, a cylinder 101 is provided on the top of the support body 100, and the piston rod at the end of the cylinder 101 pushes the left block 303, so that the sound insulation boards 200 arranged on both sides of the support body 100 are rotated and folded in the vertical direction at the same time, and the piston rod at the end of the cylinder 101 pushes the left block 303, so that the left block 303 drives the rack 301 to move away from the right block 305. When moving, the rack 301 drives the driven gear 202 to rotate in the opposite direction, so that the sound insulation boards 200 on both sides of the support body 100 are rotated to a vertical position relative to the horizontal position, so that the position between the sound insulation boards 200 is folded, thereby reducing the floor space of the device, facilitating the storage of the device, and improving the practicality of the device. At the same time, when the position for placing the device is relatively narrow, the position of the left block 303 is pushed by adjusting the piston rod at the end of the cylinder 101, so that the sound insulation boards 200 are set at the required angle, thereby solving the problem of narrow placement position and improving the practicality of the device.

[0028] In order to prevent the rack 301 from shifting in position during movement, it is clamped on the inner wall of the support body 100. Therefore, a limit groove 304 begins to be provided at the top of the rack 301. When the rack 301 moves, it fits into the limit block provided at the top of the support body 100. When the rack 301 moves, the limit groove 304 provided at the top of the rack 301 slides against the bottom of the limit block, so that the rack 301 remains horizontal during movement, thereby ensuring the efficiency of the device when unfolding and folding during use.

[0029] When the construction is completed, the device needs to be folded and stored. In order to avoid the device automatically unfolding and affecting the folding and storage efficiency, refer to Figure 4 and Figure 8 As shown, the folding and fixing assembly 400 includes a fixing block 401 sliding on the inner wall of the right block 305, and a second elastic member 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 clamped and fixed with the limiting slot 201 by the force of the second elastic member 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 drive the sound insulation board 200 to rotate, the side of the sound insulation board 200 squeezes the two sides of the fixing block 401 to make the fixing block 401 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, so that the sound insulation board 200 provided on both sides of the support body 100 rotates to Perpendicular to the horizontal direction, during the rotation of the sound insulation board 200, the outer side of the sound insulation board 200 first contacts the side of the fixed block 401. Since the two sides of the fixed block 401 are sloped, the outer side of the limiting card slot 201 fits the slope and gradually squeezes the bottom of the fixed block 401, so that the fixed block 401 slides on the top of the sound insulation board 200. When the sound insulation board 200 rotates to be perpendicular to the horizontal direction, the fixed block 401 moves downward under the force of the second elastic member 402. At this time, the fixed block 401 is located above the limiting card slot 201, so that the fixed block 401 is clamped on the inner wall of the limiting card slot 201, and the folded sound insulation boards 200 are fixed at the same time, so as to prevent the device from automatically unfolding under the force of the reset component 302 after folding, thereby improving the folding efficiency of the device.

[0030] In order to improve the stability of the device when folded and make the device stable during use, refer to Figure 4As shown, a screw 403 is provided on the top of the fixing block 401, and a thread is provided on the surface of the screw 403. The fixing block 401 connected to the inner wall of the limiting slot 201 is fixed by rotating the screw 403. When the fixing block 401 is fixed to the inner wall of the limiting slot 201, in order to avoid popping out from the inner wall of the limiting slot 201, the fixing block 401 is pressed by rotating the screw 403, thereby improving the stability of the fixing of the fixing block 401 and the limiting slot 201. When it is necessary to release the folding state of the device, the screw 403 is rotated in the reverse direction to drive the fixing block 401 away from the folding and fixing assembly 400, so that the sound insulation board 200 can be quickly unfolded to reduce external noise.
