Description

Technical Field

[0001] This invention mainly relates to the field of highway isolation equipment, specifically an isolation device with noise reduction and dust removal functions. Background Technology

[0002] Currently, residential areas along highways and elevated roads face significant dual pollution problems from traffic noise and dust, severely impacting residents' daily living experience. Fixed sound barriers have become the mainstream noise control facility in these areas, but many problems remain to be solved in their practical application. Existing fixed sound barriers are mostly monolithic panel structures, possessing only a single sound-absorbing function. They rely on the sound-absorbing material of the panels themselves for noise blocking, lacking multi-layered sound-absorbing structural designs. Their effectiveness in reducing mid-to-high frequency noise generated by vehicles is limited, and they lack accompanying dust collection structures, failing to simultaneously address highway dust pollution. Additional dust collection equipment is required, increasing overall construction and operating costs. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides an isolation device with noise reduction and dust removal functions. This device integrates both noise reduction and dust removal functions. The noise reduction structure improves noise reduction efficiency through multiple resonance and reflection effects. The spray dust removal component can achieve continuous dust purification. Moreover, each component adopts a modular design, making installation, disassembly, and maintenance convenient. It can be adapted to the usage needs of different road sections, and is especially suitable for installation and use in residential areas on both sides of highways and viaducts.

[0004] To achieve the above objectives, the present invention employs the following technical solution: An isolation device with noise reduction and dust removal functions includes multiple support columns with I-shaped cross-sections arranged at equal intervals. A base is fixedly installed on the bottom surface of the support column, and several first mounting holes are opened on the top surface of the base. Multiple noise reduction components stacked vertically are slidably installed between two adjacent support columns. A flow guiding component is fixedly installed on the upper part of the two support columns, and a spray dust removal component is provided on the top of the flow guiding component.

[0005] The soundproofing component includes a soundproof box with several evenly distributed through holes on the front, and soundproofing cotton is fixedly installed inside the soundproof box.

[0006] The soundproof box contains several echo shells that correspond one-to-one with the through holes. The through holes are connected to the inside of the echo shells, and the inner wall of the echo shells and the inner wall of the soundproof box form a resonant cavity.

[0007] Conductive holes are provided on the upper and lower parts of both sides of the echo housing. Several evenly distributed resonant rods are fixedly installed on the back of the inner wall of the echo housing. The resonant rods have a hexagonal structure, which can increase the reflective surface and improve the noise reduction effect.

[0008] The flow guiding component includes a mounting base, on the upper part of which a flow guiding block is integrally fixed. The front and rear sides of the flow guiding block are both arc-shaped structures. The spray dust removal component is set on the top of the flow guiding block. Both sides of the mounting base have reserved holes. The upper part of both sides of the support column has a second mounting hole that corresponds to the reserved holes. After inserting multiple sound insulation boxes into the U-shaped grooves of two adjacent support columns, the mounting base is inserted into them so that the mounting base is at the top. Then, the mounting base is fixed with bolts.

[0009] Both the mounting base and the guide block are box-type structures. The spray dust removal component includes a water supply pipe that extends through the rear wall of the mounting base into its interior. Several evenly distributed connecting pipes are fixedly installed on the top of a section of the water supply pipe located inside the mounting base. The connecting pipes vertically penetrate the top of the guide block and are fixedly connected to it. An atomizing nozzle is fixedly installed at the upper end of the connecting pipe. The water supply pipe is connected to a booster pump.

[0010] Several reflective blocks are fixedly installed at the front of the soundproof box, arranged along its length. The cross-section of the reflective blocks is trapezoidal, and the reflective blocks are spaced apart from the through holes.

[0011] Compared with the prior art, the beneficial effects of the present invention are: 1. This device achieves noise reflection, resonance consumption, and adsorption through the combination of reflective blocks, through holes, echo shells, resonant cavities, resonant rods, and sound-absorbing cotton. The hexagonal resonant rod increases the noise reflection surface, and the conduction holes further enhance the sound absorption effect of the resonant cavity, thereby improving the sound absorption efficiency in multiple dimensions and effectively reducing traffic noise pollution.

[0012] 2. The spray dust suppression component supplies water to the water supply pipe through a booster pump. The water is then atomized by the atomizing nozzle and sprayed evenly above the road. This can quickly absorb the dust generated by vehicles and continuously purify the dust.

[0013] 3. The support column has an I-shaped structure. The noise reduction component can be slidably installed between adjacent support columns. The flow guiding component is fixed to the support column with bolts. Each component is modularly designed. The number of noise reduction components can be flexibly adjusted according to the noise and dust conditions of the actual road section. The components are easy to disassemble and replace, reducing the later maintenance cost.

[0014] 4. The structure is stable and highly adaptable. The base at the bottom of the support column can be firmly fixed to the ground or crash barrier through the first mounting hole. The overall structure has high stability and is suitable for installation along the sides of highways or viaducts and residential areas. It can simultaneously achieve the three functions of isolation, noise reduction and dust removal, making it highly practical. Attached Figure Description

Detailed Implementation

[0017] The present invention will be further described in conjunction with the accompanying drawings and specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the invention, and these equivalent forms also fall within the scope defined in this application.

[0018] Example: An isolation device with noise reduction and dust removal functions like Figure 1-8 As shown, an isolation device with noise reduction and dust removal functions has the following specific structure: Multiple I-shaped support columns 10 are spaced at equal intervals. The support columns 10 are made of metal, have high structural strength, and can provide stable support. A base 101 is welded and fixed to the bottom surface of the support column 10. The base 101 is a square metal plate with four rectangular first mounting holes 102 on its top surface. The base 101 can be firmly fixed to the ground on both sides of the road by passing expansion bolts through the first mounting holes 102, so as to ensure the installation stability of the support column 10.

[0019] Multiple stacked sound-absorbing components 20 are slidably installed in the U-shaped groove between two adjacent support columns 10. The number of sound-absorbing components 20 can be flexibly increased or decreased according to the noise level of the road section to adapt to different sound-absorbing needs. The sound-absorbing component 20 includes a soundproof box 201, which is a rigid plastic box structure that is lightweight and has good sound insulation effect. Several through holes 202 are evenly distributed in a matrix on the front of the soundproof box 201. Noise can enter the interior of the soundproof box 201 through the through holes 202. Sound-absorbing cotton 207 is glued and fixed inside the soundproof box 201. The sound-absorbing cotton 207 is made of polyester fiber and can directly absorb some of the noise.

[0020] Inside the soundproof box 201, several echo shells 203 corresponding one-to-one with the through holes 202 are welded and fixed. The through holes 202 communicate with the interior of the echo shells 203. The echo shells 203 are hollow rectangular shells, and their inner walls form a resonant cavity 204 with the inner wall of the soundproof box 201. Noise entering the echo shells 203 will resonate in the resonant cavity 204, converting sound energy into mechanical energy and achieving noise dissipation. Conducting holes 205 are opened on the upper and lower parts of both sides of the echo shells 203. The conducting holes 205 can make the airflow and sound conduction in the resonant cavity 204 smoother, enhancing the resonance noise reduction effect. Several evenly distributed resonant rods 206 are welded and fixed to the back of the inner wall of the echo shells 203. The resonant rods 206 are hexagonal metal rods. Compared with the traditional cylindrical rods, the hexagonal structure increases the noise reflection surface, causing the noise to reflect multiple times in the echo shells 203 to dissipate its energy, further improving the noise reduction efficiency.

[0021] Several reflective blocks 50 are glued and fixed to the front of the soundproof box 201, which are arranged at equal intervals along its length. The reflective blocks 50 are made of hard rubber and have a trapezoidal cross-section. The reflective blocks 50 are spaced apart from the through holes 202. The trapezoidal reflective blocks 50 can initially reflect external noise and reduce the amount of noise that directly enters the through holes 202. At the same time, the hard rubber material can reduce the generation of secondary noise from noise impact.

[0022] A flow guiding component 30 is fixedly installed on the upper part of both support columns 10. The flow guiding component 30 includes a mounting base 301, which is a plastic box-type structure. A flow guiding block 302 is integrally welded to the upper part of the mounting base 301. The flow guiding block 302 is made of plastic and has an arc-shaped structure on both its front and rear sides. The arc-shaped structure can guide the direction of sound transmission and reduce the diffusion of noise into residential areas. Pre-drilled holes 303 are opened on both sides of the mounting base 301, and the upper parts of both sides of the support column 10 are opened through the pre-drilled holes. The second mounting hole 103 corresponds to 303. During installation, multiple soundproof boxes 201 are first inserted into the U-shaped grooves of two adjacent support columns 10 from top to bottom. Then, the mounting base 301 is inserted into the U-shaped groove at the top of the support column 10, so that the mounting base 301 is located on the top of the uppermost soundproof box 201. Then, the bolts are passed through the second mounting hole 103 and the reserved hole 303, and the mounting base 301 is fixed with the nuts. This installation method can limit the soundproofing component 20 and prevent it from sliding off.

[0023] The top of the guide block 302 is equipped with a spray dust suppression component 40. Both the mounting base 301 and the guide block 302 are box-type structures, providing installation space for the piping of the spray dust suppression component 40. The spray dust suppression component 40 includes a water supply pipe 401, which is a rigid plastic flexible hose. One end of the water supply pipe 401 extends through the rear wall of the mounting base 301 into its interior, and the other end is connected to an external water source and a booster pump. The booster pump can increase the water pressure in the water supply pipe 401 to ensure the atomization effect. The water supply pipe 401 is located in... Several evenly distributed connecting pipes 402 are bonded and fixed to the top of a section inside the mounting base 301. The connecting pipes 402 are metal rigid pipes that vertically penetrate the top of the guide block 302 and are welded and fixed to the guide block 302. The upper end of the connecting pipes 402 is threaded with an atomizing nozzle 403. The atomizing nozzle 403 is a high-pressure atomizing nozzle that can atomize the water supplied by the water supply pipe 401 into fine water droplets and spray them evenly above the road to quickly absorb the dust generated by vehicles and achieve dust removal and purification.
