Description

Technical Field

[0001] This utility model relates to the field of road engineering technology, and in particular to an ecological sound barrier. Background Technology

[0002] With the acceleration of urbanization and the booming development of transportation, highways, as an important transportation link, have seen a continuous increase in mileage. However, the noise pollution problem generated by vehicles traveling at high speeds on highways has become increasingly prominent. Relevant research data shows that the sound level of highway traffic noise is usually in the range of 70-80 decibels. Long-term exposure to such a high-intensity noise environment will have many adverse effects on the physical and mental health of surrounding residents. The hard materials such as metal and concrete used in traditional sound barriers have relatively simple appearances and are extremely inconsistent with the rich and diverse natural landscapes around highways, seriously damaging the integrity and aesthetics of the ecological landscape along the road. Moreover, due to limitations in structural design and material performance, traditional sound barriers have obvious limitations in noise reduction capabilities when facing the complex and varied terrain of highways and the diverse traffic noise spectrum. Existing metal sound barriers are easily corroded by rainwater and air after long-term exposure to the natural environment, affecting their structural strength and noise reduction effect. Therefore, we have introduced an ecological sound barrier. Utility Model Content

[0003] The main purpose of this utility model is to provide an ecological soundproof wall that can effectively solve the problems in the background technology.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] An ecological soundproof wall includes mounting plates, four of which have mounting holes at the top center of each mounting plate. A splicing device is fixedly connected to the front ends of the four mounting plates, and a sound insulation device is fixedly connected to the front end of the splicing device.

[0006] The sound insulation device includes a rock wool board, a sound-absorbing plate is fixedly connected to the front end of the rock wool board, the front end of the sound-absorbing plate has several sound-absorbing holes, an ecological panel is fixedly connected to the front end of the sound-absorbing plate, and the front end of the ecological panel has several planting troughs.

[0007] Preferably, the splicing device includes a back plate, an arc-shaped cover fixedly connected to the upper end of the back plate, a mating strip fixedly connected to the upper left and lower left ends of the back plate, a screw hole on one side of the rear end of each mating strip, a bolt threaded into each screw hole, a connecting component snapped onto the outer side of each mating strip, and the back plate fixedly connected to the front end of the mounting plate.

[0008] Preferably, the connecting assembly includes a second back plate, the upper end of which is fixedly connected to a second arc-shaped cover, the upper left end and the lower left end of the second back plate both have mating grooves, the left rear end of the second back plate has two second screw holes, and the two second screw holes are symmetrically distributed vertically, and the second back plate is snapped onto the left side of the first back plate.

[0009] Preferably, the positional dimensions of the two screw holes are adapted to the positional dimensions of the two bolts, the back plate and the shielding arc-shaped cover are both integrally formed, and the dimensions of the back plate are the same as those of the back plate.

[0010] Preferably, the docking groove penetrates the left sidewall of the second back plate, and the depth of the docking groove is adapted to the length of the docking strip, and the docking groove has an I-shaped structure.

[0011] The above solution, with its I-shaped mating groove and mating strip matching structure, allows back panel one and back panel two to be precisely positioned and tightly engaged during splicing, enhancing the stability and firmness of the splice and preventing the soundproof wall from loosening due to external forces during use.

[0012] Preferably, the rear end of the rock wool board is fixedly installed at the front end of the back plate one and the back plate two, and the plurality of sound-absorbing holes are distributed in a rectangular equidistant pattern.

[0013] The above solution ensures that the rock wool board is securely installed on the back panel, guaranteeing its stable sound absorption function during noise reduction. The rectangular equidistant holes can uniformly absorb sound waves from different directions through resonance, thus expanding the effective noise reduction range.

[0014] Preferably, the four mounting plates are symmetrically distributed in pairs, and adjacent mounting plates are spliced ​​together with their front faces flush through the splicing device.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] In this utility model, through the design of the ecological panel and the planting trough at its front end, climbing green plants can be planted. The growth of the green plants makes the appearance of the sound barrier wall blend with the natural landscape, greatly improving the ecological landscape effect along the road and changing the situation of the traditional sound barrier wall having a monotonous appearance and being out of harmony with nature.

[0017] In this invention, a multi-layer composite sound insulation device is adopted. The rock wool board uses its porous structure to convert sound energy into heat energy to achieve initial noise reduction. The sound-absorbing holes on the sound-absorbing board are distributed in a rectangular shape at equal intervals to absorb noise of specific frequencies based on the Helmholtz resonance principle. The ecological panel and the green plants planted on it reflect, block, scatter and absorb residual noise. The multi-layer structure works together to significantly improve the overall noise reduction performance for different frequencies of noise. In addition, the sound absorption characteristics of materials such as rock wool board ensure the durability of the noise reduction effect and overcome the limitations of the noise reduction performance of traditional soundproof walls.

[0018] In this invention, the splicing device adopts a combination of snap-fit ​​and bolt fixing, which facilitates the on-site installation and disassembly of the soundproof wall. When part of the soundproof wall structure is damaged, it can be easily replaced and repaired. At the same time, the one-piece molded back plate and the arc-shaped cover, as well as the arc-shaped cover structure formed after splicing, can effectively prevent rainwater, dust and other substances from entering the soundproof device, reduce the risk of internal structure corrosion, and thus extend the overall service life of the soundproof wall.

For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0027] Please see Figure 1-4 This utility model provides a technical solution:

[0028] An ecological soundproof wall includes mounting plates 1, four mounting plates 1 are provided, each mounting plate 1 has a mounting hole 2 in the middle of its upper end, and the front ends of the four mounting plates 1 are fixedly connected to a splicing device 3, and the front end of the splicing device 3 is fixedly connected to a sound insulation device 4.

[0029] The four mounting plates 1 are symmetrically distributed in pairs, and the front faces of two adjacent mounting plates 1 are spliced ​​together by the splicing device 3.

[0030] In this embodiment, the sound insulation device 4 includes a rock wool board 41, a sound-absorbing plate 42 is fixedly connected to the front end of the rock wool board 41, a plurality of sound-absorbing holes 43 are opened at the front end of the sound-absorbing plate 42, an ecological panel 44 is fixedly connected to the front end of the sound-absorbing plate 42, a plurality of planting troughs 45 are opened at the front end of the ecological panel 44, and the rear end of the rock wool board 41 is fixedly installed at the front end of the back plate 1 31 and the back plate 2 361, and the plurality of sound-absorbing holes 43 are distributed in a rectangular equidistant pattern.

[0031] Through the above scheme: when the noise generated by vehicles on the highway travels to the sound barrier, the rock wool board 41, which is the first to be affected, uses its porous structure to interact with the sound waves, converting some of the sound energy into heat energy and achieving initial noise reduction. Subsequently, the sound waves continue to propagate forward to the sound-absorbing board 42, on which the rectangularly spaced sound-absorbing holes 43 resonate and absorb noise at specific frequencies based on the Helmholtz resonance principle, further weakening the noise intensity. After the first two layers of treatment, the residual noise encounters the ecological panel 44, which acts as a reflector and blocker. Furthermore, after planting climbing greenery in the planting trough 45, the plant branches and leaves can scatter and absorb the noise. The multi-layer structure works synergistically to significantly improve the noise reduction performance and effectively reduce the impact of highway noise on the surrounding environment. The use of materials such as rock wool board 41 fully utilizes the sound absorption characteristics to ensure the durability of the noise reduction effect. The design of the ecological panel 44 and its planting trough 45 achieves a combination of noise reduction and ecological protection. Planting climbing greenery not only assists in noise reduction but also beautifies the landscape around the highway and improves the road ecological environment.

[0032] In this embodiment, the splicing device 3 includes a back plate 31. A shielding arc-shaped cover 32 is fixedly connected to the upper end of the back plate 31. A connecting strip 33 is fixedly connected to both the upper and lower left ends of the back plate 31. A screw hole 34 is opened on one side of the rear end of each connecting strip 33, and a bolt 35 is threaded into each screw hole 34. A connecting component 36 is snapped onto the outer side of each connecting strip 33. The back plate 31 is fixedly connected to the front end of the mounting plate 1. The connecting component 36 includes a second back plate 361. A shielding arc-shaped cover 362 is fixedly connected to the upper end of the second back plate 361. A shielding arc-shaped cover 362 is opened on both the upper and lower left ends of the second back plate 361. There is a mating groove 364. The rear left side of the back plate 361 has two screw holes 363, which are symmetrically distributed vertically. The back plate 361 is snapped onto the left side of the back plate 31. The position and size of the two screw holes 363 are matched with the position and size of the two bolts 35. The back plate 361 and the shielding arc-shaped cover 362 are both integrally formed. The size of the back plate 361 is the same as that of the back plate 31. The mating groove 364 penetrates the left side wall of the back plate 361. The depth of the mating groove 364 is matched with the length of the mating strip 33. The mating groove 364 has an I-shaped structure.

[0033] Through the above scheme: Backplate 1 31 is fixedly connected to the front end of mounting plate 1 as a basic splicing unit. When splicing the soundproof wall horizontally, the I-shaped mating groove 364 opened at the left end of backplate 2 361, because its depth is adapted to the length of the mating strip 33 at the left end of backplate 1 31, can be used to snap backplate 2 361 into the left side of backplate 1 31 in the horizontal direction to achieve initial positioning. Then, bolts 35 are used to pass through the screw holes 34 at the rear end of the mating strip 33 in sequence and screw into the screw holes 363 at the left rear end of backplate 2 361. Since the screw holes 363 and bolts 35 are matched in position and size, after tightening the bolts 35, backplate 1 31 and backplate 2 361 are tightly fixed. Meanwhile, the arched cover 32 at the top of the back panel 31 and the arched cover 362 at the top of the back panel 361 are spliced ​​together to form a complete arched cover structure. The combination of snap-fit ​​and bolt 35 fixation not only facilitates the on-site installation of the soundproof wall, reduces construction difficulty, and improves installation efficiency, but also enhances the tightness and stability of the splicing by the design of the I-shaped docking groove 364 and the docking strip 33. The one-piece molded back panel 361 and the arched cover 362, as well as the arched cover structure formed after splicing, can effectively prevent rainwater, dust and other substances from entering the soundproofing device 4, reduce the risk of internal structure corrosion and extend the service life of the soundproof wall.

[0034] It should be noted that this utility model is an ecological sound barrier. During installation, the sound barrier is fixed to a designated location beside the highway via mounting holes 2 in the middle of the upper ends of four mounting plates 1. Back plate 1 31 is fixedly connected to the front end of mounting plate 1, serving as the basic unit for splicing. The connecting strip 33 on the left end of back plate 1 31 and the connecting groove 364 on the left end of back plate 2 361 cooperate with each other. Since the connecting groove 364 has an I-shaped structure and its depth matches the length of the connecting strip 33, back plate 2 361 can be tightly snapped into the left side of back plate 1 31. Subsequently, bolts 35 are passed through the screw hole 34 at the rear end of the connecting strip 33 and screwed into the screw hole 363 on the left side of the rear end of back plate 2 361 to further strengthen the connection, achieving lateral splicing and expansion of the sound barrier. Simultaneously, the shielding arc-shaped cover 32 at the upper end of back plate 1 31 and the shielding arc-shaped cover 362 at the upper end of back plate 2 361 are spliced ​​together to form a complete arc-shaped shielding structure, effectively covering adjacent areas. The upper part of the back panel joint prevents rainwater and debris from entering the sound insulation device 4, protecting the internal structure. The sound insulation device 4 undertakes the main noise reduction function. The rock wool board 41 has good sound absorption performance. When the noise generated by highway vehicles propagates to the sound barrier, the sound waves enter the interior of the rock wool board 41 and interact with the porous structure. Some of the sound energy is converted into heat energy loss, achieving preliminary noise reduction. Several rectangular equidistant sound-absorbing holes 43 at the front end of the sound-absorbing board 42 use the Helmholtz resonance principle to resonate and absorb noise at specific frequencies, further weakening the noise intensity. When the noise treated by the rock wool board 41 and the sound-absorbing board 42 encounters the ecological panel 44, the ecological panel 44 plays a certain role in reflection and blocking. In addition, after planting climbing green plants in the planting trough 45 at its front end, the branches and leaves of the plants can scatter and absorb the noise, reduce the noise propagation efficiency, and beautify the surrounding environment of the highway, achieving a combination of ecological and noise reduction functions.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
