Abstract
Description
Technical Field
[0001] This utility model relates to the field of road traffic facilities technology, and in particular to an integrated sound-absorbing and insulating screen with road marker lights. Background Technology
[0002] With the acceleration of urbanization and the continuous growth of transportation demand, road traffic flow has increased significantly, leading to increasingly serious traffic noise pollution problems, especially in areas such as highways, urban expressways, and bridges. Traffic noise not only affects the quality of life of surrounding residents but may also have adverse effects on the ecological environment. To address this issue, sound-absorbing and insulating barriers have traditionally been used as noise reduction facilities on both sides of roads. Their main function is to absorb and block traffic noise through physical structures, thereby improving the acoustic environment around the road. However, existing sound-absorbing and insulating barriers are relatively simple in function, with most only possessing basic sound absorption and insulation functions. They lack integrated designs for additional functions such as lighting, protection, and heat dissipation, making it difficult to meet the comprehensive requirements of safety, intelligence, and multifunctionality in modern road construction. Especially at night or in inclement weather conditions, the lack of road outline lighting may affect driving safety, and the equipment itself is also prone to problems such as moisture, dust accumulation, and pests, affecting its service life and operational stability.
[0003] Chinese patent discloses a road noise barrier (publication number: CN 221626878 U) which includes a noise barrier and a wind power component. The noise barrier is equipped with a photovoltaic component, and the wind power component includes a generator, a rotating shaft, and wind-driven flaps. The generator is located on the noise barrier, the rotating shaft is rotatably mounted on the generator, and multiple wind-driven flaps are spaced apart around the circumference of the rotating shaft. The two ends of each wind-driven flap are connected to the two ends of the rotating shaft, and the wind-driven flaps are bent towards the end away from the rotating shaft. However, this type of road noise barrier has a single function and lacks integrated design such as lighting, protection, and heat dissipation, making it difficult to meet the comprehensive needs of modern roads for safety, intelligence, and multi-functionality. Therefore, there is a need for an integrated noise-absorbing barrier with road marker lights. Utility Model Content
[0004] The purpose of this utility model is to address the common problem in existing technologies where traditional road noise barriers have limited functionality, lack integrated designs for lighting, protection, and heat dissipation, and are unable to meet the comprehensive needs of modern roads for safety, intelligence, and multifunctionality. Therefore, this utility model proposes an integrated noise-absorbing barrier with road marker lights.
[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: An integrated sound-absorbing and insulating screen with road marker lights, comprising an outer protective shell, characterized in that: a moisture-proof bottom plate is provided at the bottom of the outer protective shell, a top cover is provided at the top of the outer protective shell, an inspection cover is provided on the top cover, multiple rows of sound-absorbing elongated holes are longitudinally spaced on one side of the outer wall of the outer protective shell, a sound-absorbing layer and a sound-insulating layer are provided inside the outer protective shell, and a functional component is provided on one side below the multiple rows of sound-absorbing elongated holes. This structure achieves overall external protection of the equipment by setting an outer protective shell; the moisture-proof bottom plate and the inspection cover at the top enhance the moisture resistance and maintainability of the equipment; the sound-absorbing holes on the outer wall provide a channel for sound to enter the interior, forming a complete sound absorption and insulation system in conjunction with the internal sound-absorbing layer and sound-insulating layer; the setting of the functional component allows the equipment to integrate other functional modules while having noise reduction functions, improving the multifunctionality and practicality of the equipment.
[0006] Preferably, the sound-absorbing layer is an internally porous sound-absorbing material, and the sound insulation layer is a high-density sound insulation board. By using porous sound-absorbing material as the sound-absorbing layer, the sound wave energy entering the equipment can be effectively absorbed, reducing noise propagation; the high-density sound insulation board, as the sound insulation layer, can reflect and block some sound waves, working synergistically with the sound-absorbing layer to achieve a more efficient noise reduction effect, thereby improving the sound environment quality on both sides of the road.
[0007] Preferably, the functional component includes an LED outline light strip, one side of which is provided with a grating refraction light guide structure. The grating refraction light guide structure is integrally molded from high-transmittance PC material, and the top of the LED outline light strip is provided with an arc-shaped waterproof plate. The LED outline light strip in the functional component can provide road contour lighting at night or in low visibility conditions, enhancing driving safety. The grating refraction light guide structure, integrally molded from high-transmittance PC material, not only achieves uniform light guidance, making the light distribution softer and the visual effect better, but also has the function of shaping and projecting light, precisely controlling the direction and range of light projection, avoiding light pollution or glare interference caused by light scattering, and improving the directionality and clarity of road lighting. The arc-shaped waterproof plate on top effectively prevents rainwater from entering the light strip area, avoiding short circuits or light source damage caused by water penetration, and improving the operational reliability and service life of the equipment in adverse weather conditions such as rain, snow, and dense fog.
[0008] Preferably, the outer protective shell has 20-30 heat dissipation holes on one side of its back surface, arranged in an equally spaced array. A power supply interface is located on one side of the heat dissipation holes. The heat dissipation holes effectively dissipate the heat generated by the internal electronic components during operation, preventing performance degradation or damage due to overheating. The equally spaced array arrangement ensures more uniform heat dissipation. The power supply interface allows for easy connection to an external power source, ensuring the normal operation of electronic components such as LED strips and improving the continuous operation capability of the device.
[0009] Preferably, an insect-proof mesh is provided at the inner port of the sound-absorbing elongated hole, and a hydrophobic coating is provided on the outer wall surface of the sound-absorbing elongated hole. The insect-proof mesh can prevent insects and other small organisms from entering the sound-absorbing hole, avoiding blockage or damage to internal components, and ensuring stable sound absorption effect; the hydrophobic coating gives the outer wall of the sound-absorbing hole good waterproof and self-cleaning ability, reducing the adhesion of rainwater, dust and other dirt, extending the cleaning cycle and service life of the equipment, and maintaining the long-term stability of appearance and function.
[0010] Preferably, the bottom of the moisture-proof base plate is provided with a plurality of drainage holes, which are evenly distributed in a matrix. The drainage holes enable the bottom of the equipment to drain water quickly, avoiding problems such as dampness and mold caused by long-term water accumulation inside; the matrix-style even distribution design makes drainage more efficient and balanced, further improving the moisture-proof performance of the equipment and ensuring the stable operation of internal electronic components and structural materials in humid environments.
[0011] The advantages of this utility model are: The integrated sound-absorbing and sound-insulating screen with road marker lights provided in this application achieves effective absorption and blocking of traffic noise by setting multiple rows of sound-absorbing elongated holes on the outer wall of the outer protective shell and rationally configuring sound-absorbing and sound-insulating layers inside, significantly improving noise reduction performance. At the same time, LED marker light strips and grating refraction light guide structures are integrated below the sound-absorbing holes, enabling the equipment to provide uniform and soft road contour lighting at night or in low visibility conditions, effectively enhancing driving safety and improving the visual guidance effect of the road. The top of the equipment is equipped with an inspection cover for easy maintenance, and the bottom moisture-proof plate and drainage hole design enhance moisture-proof and drainage capabilities, preventing internal components from being damaged by moisture and improving the durability and environmental adaptability of the equipment. The sound-absorbing holes are equipped with insect-proof nets and the outer wall is coated with a hydrophobic coating, effectively preventing insect intrusion and rainwater and dirt accumulation, ensuring unobstructed sound absorption channels and long-term stable operation of the equipment. The back of the outer protective shell is equipped with heat dissipation holes and a power supply interface, which not only provides good heat dissipation conditions for internal electronic components, but also allows the equipment to be easily connected to an external power source, ensuring the continuous and stable operation of components such as LED light strips.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model. Example
[0021] Please see Figure 1-6 As shown, an integrated sound-absorbing and sound-insulating screen with road marker lights includes an outer protective shell 4. The outer protective shell 4 is characterized by: a moisture-proof base plate 5 at its bottom; a top cover 3 at its top; an inspection cover 1 on the top cover 3; multiple rows of longitudinally spaced sound-absorbing elongated holes 2 on one side of the outer wall of the outer protective shell 4; a sound-absorbing layer 14 and a sound-insulating layer 15 inside the outer protective shell 4; and functional components on one side below the multiple rows of sound-absorbing elongated holes 2. This structure achieves overall external protection for the equipment through the outer protective shell 4. The moisture-proof base plate 5 and the inspection cover 1 at the top enhance the equipment's moisture resistance and maintainability. The sound-absorbing holes on the outer wall provide a channel for sound to enter the interior, forming a complete sound absorption and insulation system in conjunction with the internal sound-absorbing layer 14 and sound-insulating layer 15. The functional components allow the equipment to integrate other functional modules while providing noise reduction capabilities, enhancing its multifunctionality and practicality.
[0022] In this embodiment, the sound-absorbing layer 14 is an internally porous sound-absorbing material, and the sound insulation layer 15 is a high-density sound insulation board. By using porous sound-absorbing material as the sound-absorbing layer 14, the sound wave energy entering the equipment can be effectively absorbed, reducing noise propagation; the high-density sound insulation board as the sound insulation layer 15 can reflect and block some sound waves, working synergistically with the sound-absorbing layer 14 to achieve a more efficient noise reduction effect, thereby improving the sound environment quality on both sides of the road.
[0023] In this embodiment, the functional component includes an LED outline light strip 13. A grating refraction light guide structure 6 is provided on one side of the LED outline light strip 13. The grating refraction light guide structure 6 is integrally molded from high-transmittance PC material. An arc-shaped waterproof plate 7 is provided on the top of the LED outline light strip 13. The LED outline light strip 13 in the functional component can provide road outline lighting at night or in low visibility conditions, enhancing driving safety. The grating refraction light guide structure 6, integrally molded from high-transmittance PC material, not only achieves uniform light guidance, making the light distribution softer and the visual effect better, but also has the function of shaping and projecting light, accurately controlling the direction and range of light projection, avoiding light pollution or glare interference caused by light scattering, and improving the directionality and clarity of road lighting. The arc-shaped waterproof plate 7 on top effectively prevents rainwater from entering the light strip area, avoiding short circuits or light source damage caused by water penetration, and improving the operational reliability and service life of the equipment in adverse weather conditions such as rain, snow, and dense fog.
[0024] In this embodiment, the outer protective shell 4 has 20-30 heat dissipation holes 11 on one side of its back surface, arranged in an equally spaced array. A power supply interface 12 is provided on one side of each heat dissipation hole 11. The heat dissipation holes 11 effectively dissipate the heat generated by the internal electronic components during operation, preventing performance degradation or damage due to overheating. The equally spaced array arrangement ensures more uniform heat dissipation. The power supply interface 12 allows the device to be easily connected to an external power source, ensuring the normal operation of electronic components such as LED strips and improving the device's continuous operating capability.
[0025] In this embodiment, an insect-proof net 10 is provided at the inner port of the sound-absorbing elongated hole, and a hydrophobic coating 9 is provided on the outer wall surface of the sound-absorbing elongated hole. The insect-proof net 10 can prevent insects and other small organisms from entering the sound-absorbing hole, avoiding blockage of the hole or damage to internal components, and ensuring stable sound absorption effect; the hydrophobic coating 9 gives the outer wall of the sound-absorbing hole good waterproof and self-cleaning ability, reduces the adhesion of rainwater, dust and other dirt, extends the cleaning cycle and service life of the equipment, and maintains the long-term stability of appearance and function.
[0026] In this embodiment, the bottom of the moisture-proof base plate 5 is provided with a plurality of drainage holes 8, which are evenly distributed in a matrix. The drainage holes 8 enable the bottom of the equipment to drain water quickly, avoiding problems such as dampness and mold caused by long-term water accumulation inside; the matrix-style even distribution design makes drainage more efficient and balanced, further improving the moisture-proof performance of the equipment and ensuring the stable operation of internal electronic components and structural materials in a humid environment.
[0027] The implementation principle of this embodiment is as follows: When traffic noise reaches the sound barrier, the sound waves first enter the equipment through multiple rows of sound-absorbing elongated holes 2 on the outer wall of the outer protective shell 4. The design of the holes allows the sound waves to enter the internal space efficiently. Part of the sound waves that enter the interior are absorbed by the porous sound-absorbing material in the sound-absorbing layer 14. The porous structure causes the sound waves to undergo multiple reflections, friction, and heat conversions within the material, thereby converting sound energy into heat energy and achieving effective attenuation of sound wave energy. The other part of the unabsorbed sound waves propagate to the high-density sound insulation board of the sound insulation layer 15. The high-density sound insulation board reflects and blocks the sound waves, further reducing the penetration and propagation of the sound waves. Thus, a highly efficient noise reduction effect is achieved through the dual effects of "sound absorption" and "sound insulation".
[0028] At night or in low visibility conditions, after the power supply interface 12 is connected to an external power source, the LED marker light strip 13 starts to work and emits light. The light first passes through the grating refraction light guide structure 6, which is integrally molded from high-transmittance PC material. This structure can evenly disperse and refract the light, allowing it to propagate outwards in a soft and uniform manner, avoiding glare or light spots. This creates a clear and continuous contour lighting effect at the road edge, improving the visual guidance of the road, enhancing the driver's ability to identify road boundaries, and improving driving safety. The curved waterproof plate 7 at the top effectively prevents rainwater from directly entering the light strip area, avoiding short circuits or damage to the light source, and ensuring the stable operation of the lighting system.
[0029] During long-term outdoor use, the equipment faces various environmental challenges such as humidity, dust accumulation, and pests. The design of the moisture-proof base plate 5 and the drainage hole 8 allows for rapid drainage of water from the bottom of the equipment, preventing internal components from rusting or malfunctioning due to prolonged exposure to a humid environment. The insect-proof mesh 10 inside the sound-absorbing holes effectively prevents insects and other small organisms from entering the equipment, preventing blockage or damage to the internal structure. The hydrophobic coating 9 on the outer wall surface gives the sound-absorbing holes excellent waterproof and self-cleaning capabilities, reducing the adhesion of rainwater, dust, and other contaminants, and keeping the sound absorption channels unobstructed. The inspection cover 1 on the top facilitates regular inspection and maintenance of internal components by staff, allowing for timely detection and handling of potential problems. The heat dissipation holes 11 on the back ensure that the heat generated by internal electronic components, such as LED light strip driver circuits, can be dissipated in a timely manner, preventing performance degradation or component damage due to overheating, thereby ensuring long-term stable operation of the equipment under various environmental conditions.
