Description

Technical Field

[0001] This invention relates to the field of environmentally friendly transportation building technology, and in particular to an environmentally friendly sound barrier module structure and its barrier device. Background Technology

[0002] Among the various methods for preventing and controlling traffic noise pollution, setting up sound barriers is a relatively effective approach. Commonly used sound barriers consist of a steel frame and soundproof glass mounted on a foundation to reduce noise from cars driving on roads near residential areas. However, the soundproof glass used in these sound barriers is not very effective at blocking sound. Various sound barriers have been developed to address this issue. For example, patent CN 114855661 B provides a wave-shaped sound barrier and its installation method. The sound barrier includes multiple noise reduction devices and a converging device for connecting adjacent noise reduction devices. Each noise reduction device includes a positioning frame, a connector, and multiple sound insulation panels. The positioning frame has multiple mounting cavities, and each sound insulation panel is installed in one mounting cavity via a connector. The converging device includes a sound insulation strip and a fixing member. The opposite sidewalls of the sound insulation strip have insertion channels for the positioning frame to abut against, and the fixing member is used to fix the positioning frame and the sound insulation strip. The construction method includes sound insulation panel installation, positioning frame installation, and sound insulation strip installation. This application ensures the noise reduction performance of the sound barrier system and also has energy-saving and environmentally friendly effects.

[0003] However, existing sound barriers, including the aforementioned wave-shaped sound barriers and soundproof glass barriers, require large-volume or large-specification frames to fix the glass or frame during installation. This structure makes transportation very inconvenient. Sometimes, construction companies use smaller-specification modular frames to form larger frames to achieve the required area. When installing and connecting these assembled results, the gaps between them are large, which greatly reduces the noise reduction performance. The modular frames also make installation very troublesome due to their need for tightness. Summary of the Invention

[0004] This invention addresses the problem that existing sound barrier frames are too large, making them inconvenient to transport, by providing an environmentally friendly sound barrier module structure and its barrier device.

[0005] To solve the above problems, the technical solution adopted by the present invention is a sound barrier module, which is fixed on a mounting base on both sides of a traffic road, including... A rectangular module housing is provided, with the rectangular module housings being inserted one on top of the other in sequence, and the bottom rectangular module housing being fixed on a mounting base; A lifting support device is provided at the upper end inside the rectangular housing. The lifting support device includes a lifting drive, a lifting frame, and a fixing device for securing the lifted frame after it has risen. The lifting frame is vertically movable inside the rectangular housing. The lifting drive is used to raise the lifting frame. When the lifting frame in the lower rectangular housing rises, its upper end abuts against the side wall of the upper rectangular housing. Preferably, one end of the rectangular module housing has a first protrusion, and the other end of the rectangular module housing has a first groove for the protrusion to extend into, with the first protrusion and the first groove being interconnected. The first protrusion has a through slot, and the lifting frame includes a rectangular frame that slides vertically with the first slot. Through the cooperation of the groove and the protrusion, this plug-in connection not only achieves a tight connection between the modules, ensuring a stable connection, but also effectively reduces gaps during installation due to the addition of multiple corners. When sound waves enter the connection between the two rectangular module housings, they need to undergo multiple reflections, thereby improving the noise reduction performance of the sound barrier.

[0006] Preferably, the lifting drive includes a first gear, which is rotatably disposed inside a rectangular module housing. The rectangular frame is provided with a lifting rack that engages with the first gear in a gear transmission. The gear transmission between the first gear and the lifting rack enables the smooth lifting of the lifting frame, ensuring the stability and reliability of the lifting process.

[0007] Preferably, the device further includes vertical steel wires and a bending device. The vertical steel wires are located at the upper and lower ends of the rectangular module housing. The rectangular module housing has vertical insertion holes for the vertical steel wires to extend into. The ends of the vertical steel wires extend into adjacent rectangular module housings. The bending device is used to bend the vertical steel wires that have entered the rectangular module housings. The bending device bends the steel wires, enhancing the connection stability between modules, effectively preventing module swaying and displacement. The additional structural support makes the barrier more robust and able to withstand harsh weather and external impacts.

[0008] Preferably, the bending device includes rotating components, a force-applying block, and a rotating shaft. Two rotating components are rotatably mounted within the rectangular module housing via the rotating shaft. The distance between the two rotating components is greater than the diameter of the vertical reinforcing bar. The force-applying block is positioned between the two rotating components and fixedly connected to them. When the vertical steel wire extends into the rectangular module housing, the extended portion of the vertical steel wire is located on the rotation path of the force-applying block. The bending device has a simple structure and can drive multiple bending devices through a single first gear, enabling simultaneous bending of multiple steel wires.

[0009] Preferably, the rotating component includes a second gear, which meshes with the first gear. Two rotating components are provided, one on the upper side and the other on the lower side of the first gear.

[0010] Preferably, the two transverse ends of the rectangular module housing are respectively a second protrusion and a second groove that can be inserted and fitted, which increases the assembly flexibility of the sound barrier module and enables the barrier to adapt to more different installation environments and needs. This sound barrier module can be arranged not only vertically but also horizontally.

[0011] Preferably, the rectangular module housing has transverse steel wires and transverse insertion holes at both ends of the transverse steel wires. The transverse steel wires are bent in conjunction with the bending device, thereby increasing the stability of the sound barrier module in the transverse direction.

[0012] Preferably, the front side of the rectangular module housing has multiple sound inlets, and the interior of the rectangular module housing is lined with environmentally friendly sound-absorbing cotton. The sound-absorbing cotton effectively improves the noise reduction effect of the sound barrier. At the same time, the use of environmentally friendly sound-absorbing cotton aligns with modern environmental protection concepts and is beneficial to protecting the ecological environment.

[0013] The present invention also provides a barrier device, including the aforementioned sound barrier module and a top sound barrier plate. The sound barrier module allows for quick and flexible installation of the barrier device. The length and height of the barrier device can be adjusted according to actual needs, providing more flexible noise control.

[0014] As can be seen from the above technical solutions, the advantages of the present invention are: 1. Through modular design and innovative lifting support devices, the noise reduction effect of the sound barrier is not only effectively improved, but the installation process is also greatly simplified, increasing construction efficiency. Furthermore, the detachable modular design facilitates later maintenance and replacement, reducing maintenance costs.

[0015] 2. The upper and lower plug-in design of the rectangular module housing enables rapid assembly and disassembly of the modules, improving construction efficiency. The installation of a liftable frame inside the rectangular module housing strengthens the stability of the connection between the rectangular module housings and prevents tilting or shaking between them.

[0016] 3. The bending device can be used to bend both the horizontal and vertical steel wires, and the connection stability between the rectangular module shells is enhanced by simple rotation. Attached Figure Description

Detailed Implementation

[0029] To make the objectives, features, and advantages of this invention more apparent and understandable, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0030] like Figure 1-9 As shown, a sound barrier module is fixed on a mounting base 3 on both sides of a traffic road. It includes multiple rectangular module housings 1 arranged in a row and a lifting support device 2. Specifically, such as Figures 1-3 As shown, the rectangular module housing 1 is a long rectangular body. The upper end of the rectangular module housing 1 has a first rectangular protrusion 11 extending along its length. The lower end of the rectangular module housing 1 has a first groove 12 with the same shape as the first protrusion 11, into which the first protrusion 11 is inserted. The interior of the rectangular housing is hollow. A first through-slot is provided between the first protrusion 11 and the first groove 12. Figure 2As shown, the rectangular module housing 1 can be inserted vertically to form a whole panel. The lowermost rectangular module housing 1 can be fixed to both sides of the traffic road by fastening brackets 31. Concrete fixing seats 3 are generally provided on both sides of the road. The fixing bracket generally includes a horizontal support frame 311 for fixing to the concrete fixing seat 3 and a vertical support frame 312 erected on the horizontal support frame 311. The lowermost rectangular module housing 1 is fixed between the vertical support frames 312 by the first bolt 81. Then, the rectangular module housings 1 are inserted one by one. The difference between this invention and the existing stackable sound barrier panels is that the existing sound barrier panels require the installation of two high-strength... The brackets, with a height not less than the overall height of the sound barrier panel and a distance equal to the width of the sound barrier panel, are limited by the distance between the brackets when installing the sound barrier panel, making installation very inconvenient. However, the height of the vertical support bracket 312 of this invention can be lower than the height of one rectangular module housing 1. When installing other rectangular module housings 1, it is not affected by the fastening bracket 31. The rectangular module housings 1 are also very stable after being inserted vertically. Even without the limiting effect of the fastening bracket 31, the upper rectangular module housing 1 will not detach from the lower rectangular module housing 1. Furthermore, each rectangular module housing 1 is equipped with a lifting support device 2, which is located at the upper end inside the rectangular housing. Specifically, as shown... Figure 3As shown, the lifting support device 2 includes a lifting drive 21, a lifting frame 22, and a fixing device 23 for fixing the lifting frame 22 after it has risen. The lifting frame 22 includes a rectangular frame that slides vertically with the first through slot. Environmentally friendly sound-absorbing cotton 4 is installed inside the rectangular frame. The lifting frame 22 moves up and down in the first through slot under the control of the lifting drive 21. When the upper rectangular module housing 1 is inserted into the lower rectangular module housing 1, the lifting drive 21 drives the lifting frame 22 to rise. The upper end of the lifting frame 22 extends into the upper rectangular module housing 1 and is then fixed by the fixing device 23. The lifting frame 22 abuts against the side wall of the upper first through slot, thereby preventing the two rectangular module housings 1 from shaking relative to each other. It can also deliver the environmentally friendly sound-absorbing cotton 4 to the gap where the two rectangular module housings 1 are inserted. The docking design of the first groove 12 and the first protrusion 11 makes the installation between the modular rectangular module housings 1 very convenient. After insertion, the two The connection between the rectangular module housings 1 is stable and not prone to tilting, thus avoiding the need for pre-set tall supports for positioning. This prevents obstruction during installation and reduces the hassle of stacking and inserting modules. This plug-in design not only ensures a tight and stable connection between modules but also allows for the installation of a liftable lifting frame 22 within the first through-groove. The internal lifting frame 22 limits the upper and lower rectangular module housings 1, further enhancing the stability of the device. The grooves and protrusions, along with multiple corners, effectively reduce gaps during installation. When sound waves enter the connection between the two rectangular module housings 1, they undergo multiple reflections, improving the noise reduction performance of the sound barrier. In particular, the device can move sound-absorbing cotton to the gaps via the lifting frame 22, ensuring that sound waves are absorbed immediately upon entering the rectangular module housing 1, resulting in a significant noise reduction and sound insulation effect.

[0031] There are several implementations of the lifting drive 21. One implementation uses an electric telescopic rod to control the lifting of the lifting frame 22. However, this method is costly. This embodiment uses other implementations, specifically as follows: Figure 6 As shown, the lifting drive 21 includes a first gear, which is rotatably disposed inside the rectangular module housing 1. Two first rotating gears are respectively located at the midpoints of both ends of the rectangular module housing 1, as shown below. Figure 8As shown, the lifting frame 22 includes a horizontal plate 221 and vertical plates 222 on both sides of the horizontal plate 221. The vertical plates are equipped with vertical racks 2221 that mesh with the first gear. A tall sound-absorbing cotton fixing bracket 2222 is located in the middle of the vertical plate 222. Environmentally friendly sound-absorbing cotton 4 is fixed between the sound-absorbing cotton fixing brackets 2222 on both sides of the horizontal plate. The horizontal plate 221 slides within the first through groove. The width of the sound-absorbing cotton fixing bracket 2222 is narrower than the first protrusion 11. When the first gear rotates, the vertical rack 2221 rises, and the upper end of the sound-absorbing cotton fixing bracket 2222 enters the rectangular module housing 1 located above. The gear transmission between the first gear and the lifting rack enables the smooth lifting and lowering of the lifting frame 22, ensuring the stability and reliability of the lifting process. The first gear is rotated manually, such as... Figure 6 As shown, the first gear includes two transmission gear disks 211 and a first central shaft 212 connecting the two transmission gear disks 211. The first central shaft 212 has a central hole 2121. The rear panel 13 of the rectangular module housing 1 has a first rotating shaft 131 that rotatably engages with the central hole 2121. The front panel 14 of the rectangular module housing 1 has an insertion hole corresponding to the central hole 2121. The front panel 14 has a second rotating shaft 141 inside the insertion hole. The two transmission gear disks 211 rotate on the first rotating shaft 131 and the second rotating shaft 141. The central hole 2121 has a limiting function. The groove 2122 and the fixing device 23 can be inserted into the center hole 2121. In this embodiment, the fixing device 23 includes an insertion shaft 231 that is inserted into the center hole 2121. The insertion shaft 231 is provided with a limiting protrusion 232 corresponding to the limiting groove 2122. A rotating plate 233 is provided at one end of the insertion shaft 231. The rotating plate 233 and the front panel 14 are provided with corresponding bolt holes for fixing. When the first gear rotates to the specified height, the rotating plate 233 can be fixed to the front panel 14 by the second bolt 82, thereby completing the fixing of the lifting frame 22.

[0032] To further improve the connection stability between the two rectangular module housings 1, such as Figures 3-6 As shown, this sound barrier module also includes vertical steel wires 5 and bending devices 6. The vertical steel wires 5 are located at least one end of the rectangular module housing 1, either above or below. In this embodiment, the vertical steel wires 5 are located at the upper end of the rectangular module housing 1, on both sides of the first protrusion 11, near the protruding end of the rectangular module. The rectangular module housing 1 has vertical insertion holes 15 for the vertical steel wires 5 to extend into. The ends of the vertical steel wires 5 extend into adjacent rectangular module housings 1. The bending devices 6 are used to bend the vertical steel wires 5 that have entered the rectangular module housing 1. The bending devices 6 bend the steel wires, enhancing the connection stability between modules and effectively preventing module shaking and displacement. Through additional structural support, the barrier becomes more robust and can withstand severe weather and external impacts.

[0033] As a specific description of the bending device 6, such as Figure 7 As shown, the bending device 6 includes a rotating component 61, a force-applying block 62, and a rotating shaft 63. In this embodiment, two rotating components 61 are provided and rotatably mounted on one side of the first gear inside the rectangular module housing 1 via the rotating shaft 63. The distance between the two rotating plates 233 is greater than the diameter of the vertical reinforcing bar. The force-applying block 62 is located between the two rotating components 61 and is fixedly connected to them. When the vertical steel wire 5 extends into the rectangular module housing 1, the extended portion of the vertical steel wire 5 is located on the rotation path of the force-applying block 62. When two rectangular module housings are stacked vertically, the vertical steel wire located below extends into the rectangular module housing from the vertical insertion hole. The upper end of the vertical steel wire is located near the rotating shaft and higher than the rotating shaft. Figure 11 As shown, the vertical steel wire is located near the end of the rotating shaft, between the force-applying block and the rotating shaft. The bending device 6 has a simple structure and can drive multiple bending devices 6 through a first gear, enabling simultaneous bending of multiple steel wires. The rotating component 61 includes a second gear, which meshes with its corresponding first gear. When the rotating component is driven to rotate by the first gear, the force-applying block rotates accordingly, applying torque to the vertical steel wire. Under the force of the force-applying block, the vertical steel wire bends around the rotating shaft. The force-applying block of this device can rotate around the rotating shaft at an unlimited angle. As the vertical steel wire bends, its end will be lower than the force-applying block, thus completing multiple turns around the rotating shaft and achieving fixation.

[0034] In some embodiments, such as Figure 10 and 11As shown, the two transverse ends of the rectangular module housing are respectively a second protrusion 16 and a second groove 17 that can be inserted and mated. The second protrusion 16 is a rectangular protrusion extending outward from the center of the rectangular body, and the second groove 17 is a rectangular groove extending inward from the center of the rectangular body. The shape of the rectangular groove is the same as that of the rectangular protrusion. When the second groove 17 and the second protrusion 16 are inserted and mated, two adjacent rectangular module housings 1 can be fixed by the third bolt 83, ensuring that the two adjacent rectangular module housings 1 will not have relative displacement in the front-back direction. This design increases the assembly flexibility of the sound barrier module, allowing the barrier to adapt to more different installation environments and needs. This sound barrier module can be arranged not only vertically but also horizontally. This combination method is significantly different from the existing arrangement of sound baffles. Existing sound baffles require fixing two sound baffle fixing frames first during assembly, with limiting mechanisms within the sound baffle fixing frames. The gaps in the baffle modules and the baffle fixing brackets located at the connection points of the left and right baffle modules present challenges during installation. Because the length of the baffle module is exactly equal to the distance between the two baffle fixing brackets, the baffle module needs to be tilted between the two baffles before manually pressing the higher end to make it horizontal. This makes installation cumbersome. However, when assembling using the rectangular module housing 1 in this embodiment, it is not necessary to install a taller baffle fixing bracket; only the bottom rectangular module housing 1 needs to be fixed. When installing other rectangular module housings 1, there is no restriction from the baffle fixing brackets, making installation simpler. It is only necessary to ensure the stability of the connection after installation of the other rectangular module housings 1. Therefore, to increase the connection stability between two adjacent rectangular module housings 1 in the horizontal direction, transverse steel wires 9 and transverse insertion holes 18 for the transverse steel wires 9 to extend into are provided at both ends of the rectangular module housing 1. Figure 10 As shown, the transverse steel wire 9 is located in the middle of the second groove 17. There are two sets of transverse steel wires 9. Each set of transverse steel wires 9 is bent and engaged with a bending device 6. The transverse insertion hole 18 is located in the middle of the second protrusion 16, thereby increasing the stability of the sound barrier module in the transverse direction.

[0035] When the horizontal steel wire 9 is inserted into the horizontal insertion hole 18, the front end of the horizontal steel wire 9 will extend into the vicinity of the rotating shaft 63 of the corresponding bending device 6, such as... Figure 11As shown, the horizontal steel wire 9 in the upper group extends below the rotating shaft 63, and the force-applying block 62 is located to the lower right of the horizontal steel wire 9. The horizontal steel wire 9 in the lower group extends above the rotating shaft 63, and the force-applying block 62 is located to the upper left of the horizontal steel wire 9. Because the force-applying block 62 is located inside the rectangular module housing 1, its position is difficult to control. Therefore, the installation angle between the bending device 6 and the lifting drive 21 inside each rectangular module housing 1 is fixed. When the limiting groove 2122 is horizontal, the force-applying block 62 and the rotating shaft 63 are at the same horizontal height. The rotation angle of the groove 2122 corresponds to the rotation position of the force-applying block 62. Therefore, two display marks 10 can be set on the outer side of the rotating plate 233 to indicate the current position of the force-applying block 62. The two display marks respectively indicate the relative position of the upper and lower force-applying blocks 62 with the corresponding rotating shaft 63, so as to make it easy to know the angle of the force-applying block 62. When the transverse steel wire is inserted, the fixing device 23 can be rotated, and the force-applying block 62 applies force to the transverse steel wire 9, so that it rotates around the rotating shaft 63 with the rotation of the force-applying block 62, thus completing the rotation around the rotating shaft 63.

[0036] The present invention also provides a barrier device, including the aforementioned sound barrier module and a top sound barrier plate 77. The sound barrier module allows for quick and flexible installation of the barrier device. The length and height of the barrier device can be adjusted according to actual needs, providing more flexible noise control. The top sound barrier plate 77 is used to fix and connect to the first protrusion 1111 located at the topmost point. The upper end of the top sound barrier plate 77 is provided with an inclined plate, which makes the upper end of the entire sound barrier plate tilt inward, thereby enhancing the reflection effect of the sound barrier plate.

[0037] The working process of this invention is as follows: First, a rectangular module housing 1 is fixed on the fixing base 3. Then, another rectangular module housing 1 is placed on top of this rectangular module housing 1. When placing it, it is necessary to ensure that the vertical insertion hole 15 of the upper rectangular module housing 1 corresponds to the vertical steel wire 5 of the lower one. At the same time, the first protrusion 11 of the upper rectangular module housing 1 will also be inserted into the first groove 12 of the lower one. Then, the multiple rectangular module housings 1 are stacked vertically. Then, the fixing device 23 is partially inserted into the central hole 2121, and the fixing device 23 is rotated. During rotation, The fixing device 23 drives the first gear to rotate. The rotation of the first gear, in conjunction with the lifting frame 22, raises the frame. Therefore, the upper part of the lifting frame 22, equipped with environmentally friendly suction cotton, enters the rectangular module housing 1 located above. However, at this point, the lifting frame has not yet reached its highest possible position. Simultaneously, the rotation of the first gear drives the second gear to rotate, thereby causing the force-applying block 62 to rotate. The force-applying block 62 bends the vertical steel wire 5. As the first gear rotates multiple times, the vertical steel wire 5 also rotates multiple times around the rotating shaft 63, thus completing the connection and stabilization of the upper and lower rectangular module housings 1. When adding a rectangular module housing 1 in the horizontal direction, according to the indicator 10 on the force-applying block 62 at this time, pay attention to the position of the force-applying block 62. Then, first align the vertical steel wire 5 of the left rectangular module housing 1 with the vertical insertion hole 15, and then align the horizontal steel wire 9 of the left rectangular module housing 1 with the horizontal insertion hole 18 of the right rectangular module housing 1. When aligning, the rectangular module housing 1 being installed can be tilted appropriately. Then, insert the corresponding steel wire and insertion hole. After insertion, the first groove 12 and the first protrusion 11 are inserted accordingly, and the second groove 17 and the second protrusion 16 are inserted accordingly. Then, rotate the fixing device 23, and the force-applying block 62 can wrap the horizontal steel wire 9 multiple times, thereby completing the connection and stabilization of the two rectangular module housings 1 in the left and right directions. While rotating the fixing device 23, the lifting frame 22 can be further raised. After being fully raised, the lifting frame 22 can abut against the side wall of the upper rectangular module housing 1 to further improve stability. Finally, install the top sound baffle 7 on the uppermost rectangular module housing 1 to complete the assembly of the entire device.

[0038] The advantages of this invention are that the upper and lower insertion arrangement of the rectangular module housing 1 enables rapid assembly and disassembly of the module, eliminating the need for a tall fixing frame that would obstruct module installation. Furthermore, a rotatable first gear within the rectangular module housing 1 drives the lifting frame 22 to rise. The lifting frame 22 not only further strengthens the stability between the upper and lower rectangular module housings 1 but also delivers environmentally friendly sound-absorbing cotton into the gap between the two rectangular module housings 1, absorbing sound waves entering through the gap and enhancing the sound absorption effect of the device. Additionally, the rotation of the first gear drives the bending device 6 to bend and wrap the steel wire inserted into the rectangular module housing 1, further strengthening the stability between adjacent rectangular module housings 1. Through the cooperation of these multiple structures, the need for a tall fixing frame is avoided, making installation simpler and the sound insulation effect better compared to existing assembled sound baffles.

[0039] The above description of the disclosed embodiments enables those skilled in the art to make or use the invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
