Description

Technical Field

[0001] This utility model relates to the field of sound insulation board technology, specifically a ventilated noise reduction and sound insulation board for use on public roads. Background Technology

[0002] Sound insulation panels are a type of soundproofing facility. To block the direct sound between a sound source and a receiver, a device is inserted between the sound source and the receiver, resulting in a significant additional attenuation of sound wave propagation. This reduces the noise impact in a certain area where the receiver is located. They are mainly used for sound insulation and noise reduction in transportation and municipal facilities such as highways, and to reduce the impact of traffic noise on nearby urban areas by controlling traffic noise.

[0003] Existing public road sound barriers are mostly reflective sound barriers that are purely for sound insulation or composite sound barriers that combine sound absorption and sound insulation. Their functions are relatively limited, and they cannot achieve ventilation, thus affecting the road's heat dissipation and making them inconvenient to use. Utility Model Content

This solves the problem mentioned in the background that existing public road sound insulation boards are mostly purely sound-insulating reflective sound barriers and composite sound barriers that combine sound absorption and sound insulation. Their functions are relatively simple, and they cannot achieve ventilation, thus affecting the heat dissipation effect of the road and making them inconvenient to use.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a ventilated noise reduction and sound insulation panel for use on public roads, comprising a fixed base, a sound insulation panel body fixedly connected to the top of the fixed base, an air inlet on the left front end of the sound insulation panel body, mounting slots on the upper and lower sides of the air inlet, threaded holes inside the mounting slots, a filter screen plate being fitted inside the air inlet, mounting blocks fixedly connected to the upper and lower sides of the filter screen plate, and a hand-tightening bolt threaded inside the mounting blocks, an air outlet on the right rear end of the sound insulation panel body, mounting slots on the upper and lower sides of the air outlet, threaded holes inside the mounting slots, a micro-perforated resonant sound-absorbing plate being fitted inside the air outlet, mounting blocks fixedly connected to the upper and lower sides of the micro-perforated resonant sound-absorbing plate, and a hand-tightening bolt threaded inside the mounting blocks, and a through-flow duct inside the sound insulation panel body.

[0006] Preferably, the height of the through-flow duct is the same as the height of the air inlet and the air outlet, and the left end of the through-flow duct is connected to the air inlet, and the right end of the through-flow duct is connected to the air outlet.

[0007] By adopting the above technical solution, and by setting up a through-flow duct, air inlet, and air outlet in combination, airflow can enter the through-flow duct through the air inlet. The through-flow duct guides the airflow to the air outlet and discharges it through the micro-perforated resonant sound-absorbing plate, thereby achieving the function of ventilation. At the same time, the micro-perforated resonant sound-absorbing plate also suppresses noise and makes it convenient for staff to use.

[0008] Preferably, the shape and number of the first mounting block correspond to the shape and number of the first mounting slot, and the first mounting block is in close contact with the inner wall of the first mounting slot.

[0009] By adopting the above technical solution, the installation block 1 and installation slot 1 are used in conjunction with the hand-tightening bolt 1. By unscrewing the hand-tightening bolt 1, the locking of the installation block 1 can be released. At this time, the installation block 1 can be removed from the installation slot 1, and then the filter screen can be disassembled, which is convenient for staff to replace and maintain, and is convenient to use.

[0010] Preferably, there are two hand-tightening bolts, which are symmetrically distributed inside the two mounting blocks and extend into the two threaded holes.

[0011] Preferably, the shape and number of the second mounting block correspond to the shape and number of the second mounting slot, and the second mounting block is in close contact with the inner wall of the second mounting slot.

[0012] Using the above technical solution, by setting up mounting block two, mounting slot two, etc., in conjunction with hand-tightening bolt two, the locking of mounting block two can be released by unscrewing the hand-tightening bolt two. At this time, mounting block two can be removed from mounting slot two, and then the micro-perforated resonant sound-absorbing plate can be disassembled, which is convenient for staff to replace and maintain, and is convenient to use.

[0013] Preferably, there are two hand-tightening bolts, which are symmetrically distributed inside the two mounting blocks, and both hand-tightening bolts extend into the two threaded holes.

Airflow can enter the through-duct through the air inlet, and the through-duct guides the airflow to the air outlet and discharges it through the micro-perforated resonant sound-absorbing plate, thus achieving the function of ventilation. At the same time, the micro-perforated resonant sound-absorbing plate also suppresses noise and is convenient for staff to use.

[0015] 2. This ventilated noise reduction and sound insulation panel, applied to public roads, is used in conjunction with mounting blocks and mounting slots, along with a hand-tightening bolt. By unscrewing the hand-tightening bolt, the locking of mounting block one is released, allowing it to be removed from mounting slot one, and the filter screen can then be disassembled. Similarly, by unscrewing the hand-tightening bolt two, the locking of mounting block two is released, allowing it to be removed from mounting slot two, and the micro-perforated resonant sound-absorbing panel can then be disassembled. This facilitates replacement and maintenance by staff and is convenient to use. Attached Figure Description

The through-flow duct 15 guides the airflow to the air outlet 9 and discharges it through the micro-perforated resonant sound-absorbing plate 12, thereby achieving the function of ventilation. At the same time, the micro-perforated resonant sound-absorbing plate 12 also suppresses noise and is convenient for staff to use.
