Description

Technical Field

[0001] This utility model relates to the field of sound barrier technology, specifically an environmentally friendly sound barrier for highways. Background Technology

[0002] In modern transportation, the construction and development of highways have greatly promoted economic exchange and development. However, the noise generated by vehicles on highways has a serious impact on the living environment of surrounding residents. Therefore, noise barriers are widely used to reduce the noise pollution caused by highways to residents along the route.

[0003] Traditional highway noise barriers present numerous problems during installation and use. Firstly, existing technology typically uses bolts and nuts to connect multiple barriers, a cumbersome process that consumes significant manpower and time, impacting construction efficiency. Secondly, different highway sections have varying environments, and some sections may require flexible height adjustments due to surrounding buildings and environmental factors. However, most existing noise barriers have a fixed height after installation, making convenient height adjustments impossible and hindering their adaptability to complex and ever-changing application scenarios.

[0004] Therefore, this utility model provides an environmentally friendly sound barrier for highways to solve the above problems. Utility Model Content

[0008] To achieve the above objectives, this utility model provides the following technical solution: an environmentally friendly sound barrier for highways, comprising a connecting frame, a sound insulation board fixedly connected to the inner side of the connecting frame, sound-absorbing cotton fixedly connected to the back of the sound insulation board, a back plate fixedly connected to the back of the sound-absorbing cotton, two positioning seats symmetrically fixedly connected to one side of the connecting frame, and an extension component provided on the other side of the connecting frame.

[0009] The extension assembly includes a mounting box and a knob. The outer side of the mounting box is fixedly connected to the outer side of the connecting frame. One end of the knob extends through the interior of the mounting box and is fixedly connected to a drive gear. One end of the drive gear is fixedly connected to a fixing block, and the outer side of the fixing block is fixedly connected to the inner side of the mounting box. Both sides of the fixing block are rotatably connected to driven gears, and the outer edges of the two driven gears mesh with the outer edges of the drive gears. One side of each of the two driven gears is fixedly connected to a lead screw, and the outer side of each lead screw is threaded with a locking pin. The ends of the two locking pins are respectively adapted to the inner sides of the two positioning seats.

[0010] As a preferred technical solution of this application, a base plate is provided below the connecting frame, a support seat is fixedly connected to the upper surface of the base plate, and connecting plates are fixedly connected to both sides of the support seat on the upper surface of the base plate. A double-segment threaded rod is rotatably connected to the inner wall of the support seat, and two hinge seats are symmetrically threaded to the outer side of the double-segment threaded rod. A hinge frame is hinged to the top of each hinge seat, and a connecting seat is hinged between the ends of the two hinge frames. The upper surface of the connecting seat is fixedly connected to the lower surface of the connecting frame.

[0011] As a preferred technical solution of this application, a limiting post is slidably connected between the other two ends of the two hinge seats. The outer walls of the two limiting posts are fixedly connected to the inner wall of the support seat. The two ends of the two limiting posts are respectively fixedly connected to the outer sides of the two connecting plates. An adjusting plate is provided on one side of one of the connecting plates. One end of the adjusting plate passes through the inner wall of one of the connecting plates and is fixedly connected to one end of the double-segment threaded rod. The other end of the double-segment threaded rod is rotatably connected to the outer side of the other connecting plate.

[0012] As a preferred technical solution of this application, two support frames are symmetrically fixedly connected to the lower surface of the connecting frame. The bottom ends of the two support frames are fixedly connected to limit rods. The outer sides of the limit rods are slidably connected to limit seats, and the bottom ends of the limit seats are fixedly connected to the upper surface of the base plate.

[0014] As a preferred technical solution of this application, the inner side of the mounting box is symmetrically provided with two pairs of limiting grooves, and the inner side of the limiting grooves is slidably connected to the protrusion on the outer side of the locking post.

[0015] (III) Beneficial Effects

[0016] 1. By rotating the knob, the drive gear drives the two driven gears to rotate synchronously. When the two driven gears rotate, they also drive the two lead screws to rotate synchronously. As the lead screws rotate, they engage with the two locking pins through threaded connections, allowing the two locking pins to extend from the upper and lower ports of the mounting box along the inner side until their ends insert into the inner sides of the corresponding positioning seats of the adjacent soundproof screens. This completes the connection between the two soundproof screens. When disassembly is required, simply rotate the knob in the opposite direction, and the locking pins will retract into the mounting box, achieving separation. Compared with traditional bolt connections, this method is simpler to operate, significantly shortens installation time, improves construction efficiency, reduces labor costs, and solves the problem of cumbersome and time-consuming installation of existing soundproof screens.

[0017] 2. By rotating the adjustment disc to move the two hinge seats relative to each other, force is applied to the two hinge frames, causing the angle between the two hinges to change. This change in angle between the two hinge frames allows for height adjustment of the connecting seat. Simultaneously, the connecting frame and the entire sound barrier rise or fall, ensuring that the sound barrier remains in the optimal noise reduction position. This effectively solves the problem of traditional fixed-height sound barriers being difficult to adapt to complex terrains and having poor sound insulation performance, ensuring that the sound insulation function can be fully utilized under various terrain conditions.

[0025] 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.

[0026] Please see Figures 1-5 As shown, the purpose of this embodiment is to provide an environmentally friendly sound barrier for highways, including a connecting frame 1, a sound insulation board 101 fixedly connected to the inner side of the connecting frame 1, a sound-absorbing cotton 102 fixedly connected to the back of the sound insulation board 101, a back plate 103 fixedly connected to the back of the sound-absorbing cotton 102, two positioning seats 2 symmetrically fixedly connected to one side of the connecting frame 1, and an extension component provided on the other side of the connecting frame 1.

[0027] The extension assembly includes a mounting box 301 and a knob 302. The outer side of the mounting box 301 is fixedly connected to the outer side of the connecting frame 1. One end of the knob 302 extends through the interior of the mounting box 301 and is fixedly connected to a drive gear 303. One end of the drive gear 303 is fixedly connected to a fixing block 304, and the outer side of the fixing block 304 is fixedly connected to the inner side of the mounting box 301. Both sides of the fixing block 304 are rotatably connected to driven gears 305, and the outer edges of the two driven gears 305 mesh with the outer edges of the drive gear 303. One side of each of the two driven gears 305 is fixedly connected to a lead screw 306, and the outer side of each lead screw 306 is threadedly connected to a locking pin 307, and the ends of the two locking pins 307 are respectively adapted to the inner sides of the two positioning seats 2.

[0028] The inner side of the mounting box 301 is symmetrically provided with two pairs of limiting grooves 8, and the inner side of the limiting grooves 8 is slidably connected to the protrusion on the outer side of the locking post 307.

[0029] In this embodiment, when it is necessary to connect the sound barrier to an adjacent sound barrier, first ensure that the upper and lower ends of the extension component of one sound barrier correspond to the ports of the two positioning seats 2 of the other sound barrier. Then, by manually rotating the knob 302, the knob 302 will simultaneously drive the drive gear 303 to rotate. When the drive gear 303 rotates, it meshes with the two driven gears 305, thereby driving the two driven gears 305 to rotate synchronously. Then, while the two driven gears 305 are rotating, they will simultaneously drive the two lead screws 306 to rotate synchronously. As the two lead screws 306 rotate, they engage with the two locking pins 307 via threads, allowing the two locking pins 307 to extend from the upper and lower ports of the mounting box 301 along its inner side until their ends insert into the inner sides of the corresponding positioning seats 2 of the adjacent soundproof screens, thus connecting the two soundproof screens. When disassembly is required, rotating the knob 302 in the opposite direction will retract the locking pins 307 into the mounting box 301, achieving separation. This allows for the rapid splicing of multiple soundproof screens, greatly shortening installation time and improving construction efficiency.

[0030] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, a base plate 4 is provided below the connecting frame 1. A support base 401 is fixedly connected to the upper surface of the base plate 4. A connecting plate 402 is fixedly connected to both sides of the support base 401 on the upper surface of the base plate 4. A double-segment threaded rod 403 is rotatably connected to the inner wall of the support base 401. Two hinge seats 404 are symmetrically threaded to the outer side of the double-segment threaded rod 403. A hinge frame 405 is hinged to the top of each hinge seat 404. A connecting seat 406 is hinged between the ends of the two hinge frames 405. The upper surface of the connecting seat 406 is fixedly connected to the lower surface of the connecting frame 1.

[0031] Limiting posts 5 are slidably connected between the other two ends of the two hinge seats 404. The outer walls of the two limiting posts 5 are fixedly connected to the inner wall of the support seat 401. The two ends of the two limiting posts 5 are respectively fixedly connected to the outer sides of the two connecting plates 402. An adjusting plate 6 is provided on one side of one of the connecting plates 402. One end of the adjusting plate 6 passes through the inner wall of one of the connecting plates 402 and is fixedly connected to one end of the double-segment threaded rod 403. The other end of the double-segment threaded rod 403 is rotatably connected to the outer side of the other connecting plate 402.

[0032] Two support frames 7 are symmetrically fixedly connected to the lower surface of the connecting frame 1. The bottom ends of the two support frames 7 are fixedly connected to limit rods 701. Limit seats 702 are slidably connected to the outer side of the limit rods 701, and the bottom ends of the limit seats 702 are fixedly connected to the upper surface of the base plate 4.

[0033] In this implementation scheme, when the height of the sound barrier needs to be adjusted, the adjustment disc 6 is rotated to drive the double-segment threaded rod 403 to rotate synchronously along the inner wall of the support base 401. The two segments of the threaded rod 403 have opposite directions of rotation. As the double-segment threaded rod 403 rotates, it engages with the threads of the two hinge seats 404, allowing the two hinge seats 404 to move relatively linearly along the double-segment threaded rod 403. This relative movement of the two hinge seats 404 applies force to the two hinge frames 405, causing a change in the angle between the two hinges. This change in the angle between the two hinge frames 405 allows the height of the connecting seat 406 to be adjusted. Simultaneously, the connecting seat 406 is adjusted, which in turn drives the connecting frame 1 and the entire sound barrier to rise or fall. This ensures that the sound barrier is always kept in the optimal noise reduction position, effectively solving the problem of traditional fixed-height sound barriers being difficult to adapt to complex terrains and having poor sound insulation performance. This ensures that the sound insulation function can be fully utilized under various terrain conditions.

[0034] During the lifting and lowering process of the connecting frame 1, the support frame 7 plays a role in assisting the support of the sound barrier. While the connecting frame 1 is being lifted and lowered, the limit rod 701 will slide within the limit seat 702 through the support frame 7, ensuring that the sound barrier remains stable during the lifting and lowering process and will not shake or shift.

[0035] While the two hinge seats 404 are moving relative to each other, the two limiting posts 5 limit the two hinge seats 404 to ensure the stability of the hinge seats 404 during the movement.

[0036] In this embodiment, as Figure 2 As shown.

[0037] Two positioning strips 201 are fixedly connected between the ends of the two positioning seats 2 on the outside of the connecting frame 1, and the gap between the two positioning strips 201 is adapted to the outside of the mounting box 301.

[0038] In this embodiment, the gap between the two positioning strips 201 is adapted to the outer side of the mounting box 301 to limit the insertion position and direction of the mounting box 301, so that the mounting box 301 can quickly and accurately enter the predetermined position, which facilitates the connection operation between the locking post 307 and the positioning seat 2, avoids the locking post 307 from failing to be smoothly inserted into the positioning seat 2 due to installation position deviation, and improves assembly efficiency.

[0039] In summary, the working principle of this utility model is as follows:

[0040] When connecting the sound barrier to an adjacent sound barrier, first ensure that the upper and lower ends of the extension component of one sound barrier correspond to the ports of the two positioning seats 2 of the other sound barrier. Then, manually rotate the knob 302. As the knob 302 rotates, it simultaneously drives the drive gear 303 to rotate. When the drive gear 303 rotates, it meshes with the two driven gears 305, thereby driving the two driven gears 305 to rotate synchronously. Then, as the two driven gears 305 rotate, they simultaneously drive the two lead screws 306 to rotate synchronously. As the two lead screws 306 rotate, they engage with the two locking pins 307 through threaded engagement, allowing the two locking pins 307 to extend from the upper and lower ports of the mounting box 301 along the inner side of the mounting box 301 until the ends of the two locking pins 307 are inserted into the inner side of the corresponding positioning seats 2 of the adjacent sound barrier, thus completing the connection of the two sound barriers. When disassembly is required, rotate the knob 302 in the opposite direction, and the locking pins... 307 will retract into the mounting box 301, achieving separation, thus enabling the rapid splicing of multiple sound barriers. Then, depending on the different surrounding environments of the highway, by rotating the adjusting disc 6, the double-segment threaded rod 403 is driven to rotate synchronously along the inner wall of the support base 401. The two segments of the double-segment threaded rod 403 have opposite directions of rotation. As the double-segment threaded rod 403 rotates, through the threaded engagement between it and the two hinge seats 404, the two hinge seats 404 can move relatively linearly along the double-segment threaded rod 403. Then, while the two hinge seats 404 are moving relative to each other, they will apply force to the two hinge frames 405, causing the angle between the two hinge components to change. Then, by changing the angle between the two hinge frames 405, the height of the connecting seat 406 can be adjusted. While the connecting seat 406 is adjusting, the connecting frame 1 and the entire sound barrier will rise or fall synchronously, thus ensuring that the sound barrier is always kept in the optimal noise reduction position.

[0041] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
