Technical Field
[0001] This utility model relates to the field of fully enclosed sound barrier technology, specifically a lightweight fully enclosed sound barrier. Background Technology
[0002] With the rapid development of my country's economic construction, road safety equipment is also constantly being updated. Fully enclosed sound barrier panels use curved surfaces to cover both sides of the road. Firstly, they can isolate the noise of passing vehicles on both sides of the road through sound insulation panels. Secondly, they can absorb the noise passing through this relatively enclosed road section, thereby achieving a sound shielding effect to ensure the tranquility of the lives of residents around the road.
[0003] Existing patent CN221167519U proposes a fully enclosed sound barrier, which includes: a support assembly and a sound insulation panel, wherein the support assembly is snapped into the sound insulation panel; the support assembly includes an outer baffle, a rib plate, an inner baffle, small bolt holes, fastening bolts, a rotating shaft, a fastening sleeve, a knob, an upper connecting rod, a connecting shaft, and a lower connecting rod, so that the mounting brackets of the partition panel become movable connections, which not only allows for the installation of sound insulation panels of various widths according to actual conditions, saving costs, but also ensures that the partition panels are on the same mounting plane, making installation more convenient and faster, more aesthetically pleasing, and easier to disassemble and maintain.
[0004] However, the aforementioned equipment uses bolts to fix the sound insulation panel between the outer and inner barriers, which is not secure enough. The sound insulation panel is prone to shaking between the outer and inner barriers due to airflow and vibration, thus generating noise. At the same time, the sealing effect of the gaps at the joints is not good, resulting in poor noise reduction effect. Furthermore, most existing lightweight fully enclosed sound barriers ventilate by opening ventilation holes at the top, allowing air to circulate, which will affect the noise reduction effect of the lightweight fully enclosed sound barrier.
[0005] Based on this, a lightweight, fully enclosed sound barrier is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content
[0006] The purpose of this invention is to provide a lightweight, fully enclosed sound barrier to solve the problems of poor noise reduction at ventilation openings and joints in the prior art.
[0007] To achieve the above objectives, this utility model provides the following technical solution: A lightweight, fully enclosed sound barrier includes a support beam with two connecting grooves on both sides. Sound insulation cotton is installed inside the connecting grooves, and cushioning cotton is installed on one side of the sound insulation cotton. A ventilation component is slidably connected in the middle of the connecting groove. The ventilation component includes a noise reduction plate, which is slidably connected in the middle of the connecting groove. A ventilation pipe is installed on the top of the noise reduction plate. Sound-absorbing cotton is installed on the inner wall of the ventilation pipe. Sound-absorbing mesh is installed around the inner side of the sound-absorbing cotton. A ventilation opening is installed on the top of the ventilation pipe. Two sound-absorbing plates are installed inside the ventilation opening. Sound insulation components are installed on both sides of the support beam.
[0008] Based on the above technical solutions, this utility model also provides the following optional technical solutions: In one alternative: connecting seats are installed on both sides of the bottom of the support beam, and four fixing slots are provided around the connecting seats.
[0009] In one alternative: a sound barrier is slidably connected to both sides of the inner side of the connecting groove, and an arc-shaped barrier is fitted to the top of both sides of the connecting groove.
[0010] In one alternative: sound-insulating and noise-reducing glass is slidably connected to the top two sides of the connecting groove, and connecting bolts are connected through the two sides of the supporting beam.
[0011] In one alternative: the sound insulation component includes a sound insulation groove, which is installed on both sides of the support beam. A sliding hole is provided inside the sound insulation groove, and a sound insulation plate is slidably connected inside the sliding hole. A limit plate is installed on the top of the sound insulation plate, and a handle is installed on the top of the limit plate.
[0012] In one alternative: the sound insulation groove encloses two symmetrical connecting bolts on the left and right sides of the support beam.
[0013] In one alternative: the sound-absorbing panel is tilted at an angle, and two noise-reducing meshes are provided on both sides of the sound-absorbing panel.
[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model, through the setting of ventilation components, allows airflow to be discharged through the interior of the ventilation pipe and the ventilation opening during use. The ventilation pipe absorbs noise through the internal sound-absorbing cotton and sound-absorbing mesh, and the ventilation opening reduces noise through the two internal sound-absorbing panels. This avoids the problems of conventional ventilation openings lacking noise reduction structure and having insufficient noise reduction effect, thus improving the noise reduction and sound insulation effect.
[0015] 2. This utility model uses sound-insulating cotton and buffer cotton inside the connecting groove to fit and wrap the sliding connection structure inside the connecting groove, thereby filling the gaps. When subjected to vibration, the buffer plate wraps and cushions the vibration, and the sound-insulating cotton reduces noise, thus improving the noise reduction effect at the connection. The sound-insulating component wraps the outside of the connecting bolt, thereby sealing and reducing noise at the connection, avoiding the problems of poor noise reduction effect at the connection and water ingress and rusting of the connecting bolt.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.
[0022] In one embodiment, such as Figures 1-4 As shown, a lightweight, fully enclosed sound barrier includes a support beam 1, with two connecting grooves 11 on both sides of the support beam 1. Sound insulation cotton 12 is installed inside the connecting grooves 11, and a buffer cotton 13 is installed on one side of the sound insulation cotton 12. A ventilation component is slidably connected to the middle of the connecting groove 11. The ventilation component includes a noise reduction plate 3, which is slidably connected to the middle of the connecting groove 11. A ventilation pipe 31 is installed on the top of the noise reduction plate 3. Sound-absorbing cotton 32 is installed on the inner wall of the ventilation pipe 31. Sound-absorbing mesh 33 is installed around the inner side of the sound-absorbing cotton 32. A ventilation opening 34 is installed on the top of the ventilation pipe 31. Two sound-absorbing plates 35 are installed inside the ventilation opening 34. Sound insulation components are installed on both sides of the support beam 1.
[0023] In this embodiment, the sound insulation cotton 12 and buffer cotton 13 inside both sides of the support beam 1 wrap the internal sliding connection structure. When vibration occurs, the buffer cotton 13 buffers the vibration, and the sound insulation cotton 12 wraps the structure to reduce noise and prevent noise from impacting the connection and the problem of poor noise reduction effect at the connection. The sound-absorbing cotton 32 and sound-absorbing mesh 33 inside the ventilation pipe 31 reduce the noise passing through the ventilation pipe 31. The two inclined sound-absorbing plates 35 inside the ventilation opening 34 facilitate air circulation and improve the noise reduction and sound insulation effect.
[0024] In one embodiment, such as Figure 1 and Figure 2 As shown, connecting seats 14 are installed on both sides of the bottom of the support beam 1. Four fixing slots 15 are opened around the connecting seats 14. The connecting seats 14 are connected to the ground by connecting rivets or bolts passing through the fixing slots 15.
[0025] In one embodiment, such as Figure 1 and Figure 2 As shown, a sound barrier 16 is slidably connected to both sides of the inside of the connecting groove 11, and an arc-shaped barrier 17 is fitted to the top of both sides of the connecting groove 11. Both the sound barrier 16 and the arc-shaped barrier 17 are lightweight sound insulation structures.
[0026] In one embodiment, such as Figure 1 and Figure 2 As shown, sound-insulating and noise-reducing glass 18 is slidably connected to the top two sides of the connecting groove 11, and connecting bolts 19 are connected through the two sides of the support beam 1. The lighting effect is improved by setting the sound-insulating and noise-reducing glass 18, and the sound barrier 16 is fixed to the two sides of the support beam 1 by the connecting bolts 19 passing through the support beam 1 and the sound barrier 16.
[0027] In one embodiment, such as Figure 1 and Figure 3 As shown, the sound insulation component includes a sound insulation groove 2, which is installed on both sides of the support beam 1. A sliding hole 21 is provided inside the sound insulation groove 2, and a sound insulation plate 22 is slidably connected inside the sliding hole 21. A limiting plate 23 is installed on the top of the sound insulation plate 22, and a handle 24 is installed on the top of the limiting plate 23. The sound insulation groove 2 wraps around two symmetrical connecting bolts 19 on one side of the support beam 1. By pushing the handle 24, the sound insulation plate 22 slides inside the sliding hole 21, thereby sealing the sound insulation groove 2 and sealing the connection of the connecting bolts 19, achieving the effect of waterproofing and noise reduction.
[0028] In one embodiment, such as Figure 1 , Figure 2 and Figure 3 As shown, the sound insulation groove 2 wraps around the two symmetrical connecting bolts 19 on the left and right sides of the support beam 1. By wrapping the two symmetrical connecting bolts 19 on one side of the support beam 1 with the sound insulation groove 2, the effect of noise reduction, sound insulation and waterproofing is achieved.
[0029] In one embodiment, such as Figure 1 and Figure 4 As shown, the sound-absorbing panel 35 is tilted at an angle, and two noise-reducing meshes are provided on both sides of the sound-absorbing panel 35. The tilted angle of the sound-absorbing panel 35 and the noise-reducing meshes on both sides facilitate the absorption and reduction of noise.
[0030] The above embodiment discloses a lightweight, fully enclosed sound barrier. The connecting seat 14 is fixed by bolts or rivets passing through the fixing groove 15, thereby fixing the support beam 1. The sound barrier 16, sound-insulating and noise-reducing glass 18, and noise-reducing panel 3 are slidably connected by the connecting grooves 11 on both sides of the support beam 1, and the arc-shaped barrier 17 is fitted together. Sound-insulating cotton 12 and buffer cotton 13 inside the connecting groove 11 wrap the internal structure of the connecting groove 11, thereby buffering vibration and providing sound insulation, avoiding sound leakage at the connection point. Connecting bolts 19 pass through the support beam 1 and the sound barrier 16, thereby connecting and fixing the sound barrier 16, improving the stability of the connection. By pushing the handle 24, the sound insulation plate 22 slides downward inside the sliding hole 21 and is limited by the limiting plate 23, thereby sealing one side of the sound insulation groove 2. This provides waterproofing, noise reduction, and sound insulation treatment for the connection of the connecting bolt 19, avoiding the problems of poor noise reduction effect at the connection and the rusting of the connecting bolt 19 when exposed to water, which affects the noise reduction effect. Ventilation is provided through the ventilation pipe 31. When the air circulates inside the ventilation pipe 31, the noise is absorbed and reduced by the sound-absorbing cotton 32 and the sound-absorbing mesh 33. The air is guided by two inclined sound-absorbing plates 35 inside the ventilation port 34, which absorb and reduce the noise in the air. The noise reduction mesh set on both sides of the sound-absorbing plate 35 improves the noise reduction effect.
[0031] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
