Description

Technical Field

[0001] This invention relates to the field of sound insulation technology for road and bridge engineering, specifically to a multifunctional sound barrier device for roads and bridges. Background Technology

[0002] With social progress and urban development, people's living standards are constantly improving, and urban and intercity transportation has become one of the most closely related issues to our lives. While urban transportation brings convenience to citizens, it also poses significant hidden dangers to environmental noise and vibration pollution. As more and more transportation lines are put into operation, people have realized the importance of vibration reduction and noise reduction. Sound barriers should be installed in noise-sensitive areas on both sides of urban roads to reduce noise. Therefore, sound barrier series silencing equipment has a large market application space. Therefore, reducing noise pollution to residents on both sides of roads has become an important task in my country's current urban construction. In order to improve the living environment of citizens, relevant departments have installed various sound barriers on both sides of roads. However, most traffic sound barriers at present are standalone sound-absorbing products with very limited functions. They cannot meet the diverse needs of roads when facing problems such as drainage, solar glare, and pollution.

[0003] Furthermore, with the rapid development of roads and bridges, the accompanying issues of vehicle safety have become increasingly apparent. Because roads and bridges are elevated, vehicles traveling on them are frequently affected by crosswinds, leading to accidents. Therefore, to ensure vehicle safety, windbreaks are typically installed on both sides of the road to block crosswinds. While existing road and bridge windbreaks can block crosswinds, their poor design and installation result in ineffective wind protection, unstable structures prone to breakage, and disruption to traffic. Moreover, their function is limited, only providing wind protection and failing to fulfill functions similar to sound barriers, leading to a waste of resources. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a multifunctional sound barrier device for roads and bridges. The sound barrier device of this invention has multiple functions, including automatic adjustment of sound insulation and noise reduction, dust absorption, anti-reflective properties, wind protection, and lighting, meeting various road usage requirements. This multifunctional sound barrier device is feature-rich, highly adaptable to the environment, simple in manufacturing process, and has low operating and maintenance costs.

[0005] To achieve the above objectives, the present invention provides a multifunctional sound barrier device for roads and bridges, which mainly includes a windproof and sound-insulating shell and multiple interconnected sound-absorbing and noise-reducing panels. The windproof and sound-insulating shell has an overall arc-shaped structure.

[0006] Both the windproof and soundproof housing and the sound-absorbing and noise-reducing panel have louver structures. The louver structure of the windproof and soundproof housing includes multiple parallel first louver strips, and the louver structure of the sound-absorbing and noise-reducing panel includes multiple parallel second louver strips. The first louver strips are arc-shaped, and the second louver strips are triangular. Both the first and second louver strips can be rotated at a certain angle as needed.

[0007] The multiple interconnected sound-absorbing and noise-reducing panels are arranged in order of tilt from top to bottom on the inner side of the windbreak and sound insulation shell facing the road and bridge direction.

The upper end of the uppermost sound-absorbing and noise-reducing panel is connected to the top of the windbreak and sound insulation shell, and the lower end of the lowermost sound-absorbing and noise-reducing panel is connected to the bottom of the windbreak and sound insulation shell.

[0008] The surfaces of the first and second louvers are covered with sound-absorbing and sound-insulating materials, and the surfaces of the sound-absorbing and sound-insulating materials are provided with recessed structures of varying depths.

[0009] A dust-collecting mesh is provided on the inner surface of the windproof and soundproof housing.

[0010] Preferably, the overall curvature of each of the first 100-leaf strips is not exactly the same and they are arranged continuously, so that when the whole is completely closed, it can ensure the formation of a closed arc-shaped windproof and soundproof shell.

[0011] In any of the above embodiments, it is preferred that a portion of the first louver of the louver structure of the windproof and soundproof housing be kept in a normally open state, that is, so that the windproof and soundproof housing in this range has gaps, thereby forming a negative pressure in the inner space of the windproof and soundproof housing by the action of external wind force, causing dust generated on roads and bridges to be deposited in the recessed structure and the dust collection net, thereby achieving a stronger dust collection effect; the range here starts from the top of the windproof and soundproof housing downwards and occupies 1 / 4 of the overall height of the windproof and soundproof housing.

[0012] In any of the above embodiments, it is preferred that the recessed structure is in the form of a rhombus, triangle, square, or elongated groove, so that dust generated on roads and bridges can be deposited inside.

[0013] In any of the above solutions, it is preferred that the first louver and the second louver can be rotated at a certain angle as needed. This means that the rotation of the first louver and the second louver is controlled according to the magnitude of the external wind force and / or the noise level of the road and bridge, so that the corresponding louver structure can be opened at a certain angle and / or completely closed.

[0014] In any of the above embodiments, preferably, the multifunctional sound barrier device is further provided with a control module, a first motor, a second motor, a first louver actuator, a second louver actuator, a noise sensor, and a wind sensor. The control module has preset noise thresholds and wind thresholds. The first motor drives the first louver actuator to rotate the first louver slats, and the second motor drives the second louver actuator to rotate the second louver slats. The control module can control the first motor and the second motor individually or simultaneously.

[0015] In any of the above embodiments, it is preferred that a wind force sensor is provided on the outer side of the windproof and soundproof housing, and a noise sensor is provided on the sound-absorbing and noise-reducing plate; both the first louver actuator and the second louver actuator are linkage-type structures.

[0016] In any of the above embodiments, it is preferred that a water guide channel is provided at the connection between the inner bottom of the windproof and soundproof shell and the road bridge, and the top of the water guide channel is covered with a cover plate with multiple through holes; the bottom of the water guide channel is connected to multiple drainage pipes, and the other end of the drainage pipes can be connected to the rainwater drainage pipe of the road bridge.

[0017] In any of the above embodiments, it is preferred that a solar charging module is provided on the top of the windproof and soundproof housing to provide energy for the operation and lighting of the entire multifunctional sound barrier device; and that lighting lamps are provided on the top frame and side frame of the windproof and soundproof housing, as well as the top and bottom frames and side frame of the sound-absorbing and noise-reducing panel.

[0018] In any of the above embodiments, it is preferred that the inner side of the windproof and soundproof housing, the outer side facing away from the road and bridge, and the surface of the sound-absorbing and noise-reducing panel are all coated with an anti-reflective layer.

[0019] The beneficial effects of this invention are:

[0020] 1. The sound barrier device of the present invention has multiple functions such as automatic adjustment of sound insulation and noise reduction, dust absorption, anti-reflection, wind blocking, and lighting, which meet the diverse needs of roads; the multifunctional sound barrier device has rich functions, strong adaptability to the environment, simple process, and low operation and maintenance costs.

[0021] 2. This invention can adjust the rotation angle of the first and second louvers according to the noise and wind force, thereby changing the shape of the windbreak and sound insulation shell and the sound-absorbing and noise-reducing panel, achieving excellent effects in strengthening noise isolation and blocking crosswinds, further improving driving safety and reducing noise pollution on roads and bridges. It is versatile and easy to use.

[0022] 3. This invention, through the structural design of the windproof soundproof shell and the sound-absorbing and noise-reducing panels, as well as their respective louver structures, significantly attenuates the propagation of noise waves, achieving excellent sound absorption and insulation effects, thereby reducing the noise impact in the area and achieving the purpose of noise reduction; in rainy or snowy weather, the water flow generated inside the sound barrier device can be collected through the water guide channel and discharged outside the road and bridge area, effectively solving the road drainage problem in the area where the sound barrier device is located and preventing adverse effects on the safety of vehicles and pedestrians.

[0026] The technical solution of this application will be described in detail below with reference to the specific embodiments and accompanying drawings. However, the following embodiments are only used to understand the present invention. The embodiments and features in the embodiments of this application can be combined with each other. This application can be implemented in a variety of different ways as defined and covered by the claims.

[0027] Example 1

[0028] See Figure 1-3 A multifunctional sound barrier device for roads and bridges mainly includes a windproof and sound-insulating shell 1 and multiple interconnected sound-absorbing and noise-reducing panels 2. The windproof and sound-insulating shell 1 has an overall arc-shaped structure.

[0029] Both the windproof and soundproof housing 1 and the sound-absorbing and noise-reducing panel 2 have louver structures. The louver structure of the windproof and soundproof housing 1 includes multiple parallel first louver strips 3, and the louver structure of the sound-absorbing and noise-reducing panel 2 includes multiple parallel second louver strips 4. The first louver strips 3 are arc-shaped, and the second louver strips 4 are triangular. Both the first louver strips 3 and the second louver strips 4 can be rotated at a certain angle as needed.

[0030] The multiple interconnected sound-absorbing and noise-reducing panels 2 are arranged in order of tilt from top to bottom on the inner side of the windbreak and sound insulation shell 1 facing the road and bridge direction, and the upper and lower ends of adjacent sound-absorbing and noise-reducing panels 2 are connected to each other. The uppermost sound-absorbing and noise-reducing panel 2 is connected to the top of the windbreak and sound insulation shell 1, and the lowermost sound-absorbing and noise-reducing panel 2 is connected to the bottom of the windbreak and sound insulation shell 1.

[0031] The surfaces of the first louver 3 and the second louver 4 are both covered with sound-absorbing and sound-insulating material, and the surface of the sound-absorbing and sound-insulating material is provided with a recessed structure of varying depths.

[0032] The inner surface of the windshield and soundproof housing 1 is equipped with a dust-collecting net, which can intercept dust, garbage, and other debris generated on roads and bridges. When vehicles travel on roads and bridges, due to the high speed, the airflow generated blows dust, garbage, and other debris toward the multi-functional sound barrier device, where the dust-collecting net intercepts them. Therefore, even when the first louver 3 is kept open, dust and garbage will not escape beyond the road and bridge area, maximizing the dust removal and suction effect.

[0033] The overall curvature of each of the first 100-leaf strips 3 is not exactly the same, and they are arranged continuously, so that when the whole is completely closed, it can ensure the formation of a closed arc-shaped windproof and soundproof shell 1.

[0034] A portion of the first louver slats 3 of the louver structure of the windproof and soundproof housing 1 can remain in a normally open state. That is, when the first louver slats 3 rotate to open the upper space of each first louver slat 3, the windproof and soundproof housing 1 in this range has gaps. When the external crosswind blows through this range, a negative pressure is formed in the inner space of the windproof and soundproof housing 1 by the action of the external wind force, so that the dust generated on the road and bridge is deposited in the recessed structure and the dust collection net, thereby enhancing the dust collection effect. This range starts from the top of the windproof and soundproof housing 1 downwards and occupies 1 / 4 of the overall height of the windproof and soundproof housing 1.

[0035] The recessed structures can take the form of rhombuses, triangles, squares, or elongated grooves, allowing dust generated on roads and bridges to accumulate. Because the amount of dust deposited within these recessed structures varies, the resulting differences in their internal structures further enhance the impact interference of noise wave reflection, thus further strengthening the noise attenuation effect.

[0036] The first louver 3 and the second louver 4 can both rotate at a certain angle as needed. This means that the rotation of the first louver 3 and the second louver 4 is controlled according to the magnitude of the external wind force and / or the noise level of the road and bridge, so that the corresponding louver structure can be opened at a certain angle and / or completely closed. In this embodiment, the first louver 3 and the second louver 4 are rotated by 30°, so that the corresponding louver structure is fully opened.

[0037] The multifunctional sound barrier device is also equipped with a control module, a first motor, a second motor, a first louver actuator, a second louver actuator, a noise sensor, and a wind sensor. The control module has preset noise thresholds and wind thresholds. The first motor drives the first louver actuator to rotate the first louver slat 3, and the second motor drives the second louver actuator to rotate the second louver slat 4. The control module can control the first motor and the second motor individually or simultaneously.

[0038] A wind sensor is installed on the outer side of the windproof and soundproof housing 1, and a noise sensor is installed on the sound-absorbing and noise-reducing plate 2; both the first louver actuator and the second louver actuator are linkage-type structures.

[0039] A water guide channel is provided at the connection between the inner bottom of the windproof and soundproof housing 1 and the road and bridge. The top of the water guide channel is covered with a cover plate with multiple through holes. The bottom of the water guide channel is connected to multiple drainage pipes, and the other end of the drainage pipes can be connected to the rainwater drainage pipes of the road and bridge.

[0040] The top of the windproof and soundproof housing 1 is equipped with a solar charging module to provide energy for the operation and lighting of the entire multifunctional sound barrier device; the top frame and side frame of the windproof and soundproof housing 1, as well as the top and bottom frames and side frames of the sound-absorbing and noise-reducing panel 2, are all equipped with lighting lamps.

[0041] The inner side of the windproof and soundproof housing 1, the outer side facing away from the road and bridge, and the surface of the sound-absorbing and noise-reducing plate 2 are all coated with an anti-reflective layer.

[0042] In this embodiment, the overall arc-shaped structure of the windshield sound insulation shell 1 enhances the sound-gathering effect and prevents vehicle noise from spreading beyond the road and bridge area. The overall shape of the windshield sound insulation shell 1 and the arrangement of the sound-absorbing and noise-reducing panel 2 complement each other. In addition, the triangular structure of the second louver 4 will cause the sound wave reflection of vehicle noise gathered inside the windshield sound insulation shell 1 to be attenuated due to the chaotic and disordered mutual collision and interference, thus achieving a good sound absorption effect.

[0043] The surfaces of the first louver 3 and the second louver 4 are both covered with sound-absorbing and sound-insulating material, which further ensures the sound absorption and sound insulation effect. The surface of the sound-absorbing and sound-insulating material is provided with a recessed structure of varying depths, which further causes noise sound waves to collide and interfere with each other. Thus, the overall structure of the sound barrier device and the fine structure of the louvers comprehensively ensure the sound absorption and sound insulation effect.

[0044] The sound-absorbing and noise-reducing panel 2 consists of 3 pieces.

[0045] Example 2

[0046] See Figure 1-3A multifunctional sound barrier device for roads and bridges mainly includes a windproof and sound-insulating shell 1 and multiple interconnected sound-absorbing and noise-reducing panels 2. The windproof and sound-insulating shell 1 has an overall arc-shaped structure.

[0047] Both the windproof and soundproof housing 1 and the sound-absorbing and noise-reducing panel 2 have louver structures. The louver structure of the windproof and soundproof housing 1 includes multiple parallel first louver strips 3, and the louver structure of the sound-absorbing and noise-reducing panel 2 includes multiple parallel second louver strips 4. The first louver strips 3 are arc-shaped, and the second louver strips 4 are triangular. Both the first louver strips 3 and the second louver strips 4 can be rotated at a certain angle as needed.

[0048] The multiple interconnected sound-absorbing and noise-reducing panels 2 are arranged in order of tilt from top to bottom on the inner side of the windbreak and sound insulation shell 1 facing the road and bridge direction, and the upper and lower ends of adjacent sound-absorbing and noise-reducing panels 2 are connected to each other. The uppermost sound-absorbing and noise-reducing panel 2 is connected to the top of the windbreak and sound insulation shell 1, and the lowermost sound-absorbing and noise-reducing panel 2 is connected to the bottom of the windbreak and sound insulation shell 1.

[0049] The surfaces of the first louver 3 and the second louver 4 are both covered with sound-absorbing and sound-insulating material, and the surface of the sound-absorbing and sound-insulating material is provided with a recessed structure of varying depths.

[0050] A dust-collecting net is provided on the inner surface of the windproof and soundproof housing 1.

[0051] The overall curvature of each of the first 100-leaf strips 3 is not exactly the same, and they are arranged continuously, so that when the whole is completely closed, it can ensure the formation of a closed arc-shaped windproof and soundproof shell 1.

[0052] The first louver 3 of the louver structure of the windproof and soundproof housing 1 can be kept in a normally open state, that is, the windproof and soundproof housing 1 in this range has gaps, thereby forming a negative pressure in the inner space of the windproof and soundproof housing 1 by the action of external wind force, so that the dust generated on the road and bridge is deposited in the recessed structure and the dust collection net, thereby achieving a stronger dust collection effect; the range is from the top of the windproof and soundproof housing 1 downwards and accounts for 1 / 4 of the overall height of the windproof and soundproof housing 1.

[0053] The recessed structure can take the form of a rhombus, triangle, square, or elongated groove, and dust generated on roads and bridges can be deposited inside it.

[0054] The first louver 3 and the second louver 4 can both rotate at a certain angle as needed. This means that the rotation of the first louver 3 and the second louver 4 is controlled according to the magnitude of the external wind force and / or the noise level of the road and bridge, so that the corresponding louver structure can be opened at a certain angle and / or completely closed. In this embodiment, the first louver 3 and the second louver 4 rotate at least 15° to open the corresponding louver structure.

[0055] The multifunctional sound barrier device is also equipped with a control module, a first motor, a second motor, a first louver actuator, a second louver actuator, a noise sensor, and a wind sensor. The control module has preset noise thresholds and wind thresholds. The first motor drives the first louver actuator to rotate the first louver slat 3, and the second motor drives the second louver actuator to rotate the second louver slat 4. The control module can control the first motor and the second motor individually or simultaneously.

[0056] A wind sensor is installed on the outer side of the windproof and soundproof housing 1, and a noise sensor is installed on the sound-absorbing and noise-reducing plate 2; both the first louver actuator and the second louver actuator are linkage-type structures.

[0057] A water guide channel is provided at the connection between the inner bottom of the windproof and soundproof housing 1 and the road and bridge. The top of the water guide channel is covered with a cover plate with multiple through holes. The bottom of the water guide channel is connected to multiple drainage pipes, and the other end of the drainage pipes can be connected to the rainwater drainage pipes of the road and bridge.

[0058] The top of the windproof and soundproof housing 1 is equipped with a solar charging module to provide energy for the operation and lighting of the entire multifunctional sound barrier device; the top frame and side frame of the windproof and soundproof housing 1, as well as the top and bottom frames and side frames of the sound-absorbing and noise-reducing panel 2, are all equipped with lighting lamps.

[0059] The inner side of the windproof and soundproof housing 1, the outer side facing away from the road and bridge, and the surface of the sound-absorbing and noise-reducing plate 2 are all coated with an anti-reflective layer.

[0060] Furthermore, in order to further improve the technical effect of the present invention, in this embodiment, the sound-absorbing and noise-reducing plate 2 is provided with 7 pieces.

[0061] When the noise from vehicles on the road or bridge detected by the noise sensor exceeds the noise threshold, the control module controls the first motor drive, which in turn drives the first louver actuator to adjust the rotation angle of the first louver slat 3, thereby achieving the effect of blocking and attenuating the noise and ensuring noise reduction.

[0062] When the wind force detected by the wind sensor exceeds the wind force threshold, the control module controls the second motor drive, which in turn drives the second louver actuator to adjust the rotation angle of the second louver slats 4. This causes the windshield sound insulation shell 1 to open a certain gap, allowing some of the external crosswind to pass through. The beneficial effect of this is that when the external crosswind is strong, it exerts a significant external force on the windshield sound insulation shell 1, which can eventually damage its strength and overall structure. Through the above detection and control, the windshield sound insulation shell 1 opens a certain gap, allowing some of the external crosswind to pass through. This alleviates the strong external force exerted by the external crosswind on the windshield sound insulation shell 1, and the wind force passing through the gap disrupts the vehicle noise trapped inside the windshield sound insulation shell 1. This ensures that the windshield sound insulation shell 1 is not damaged, and further guarantees the sound insulation and noise reduction effect—a double benefit.

[0063] Furthermore, multiple first motors can be configured, meaning a separate first motor can be installed on each sound-absorbing and noise-reducing panel 2, thereby achieving individual control of each panel 2. This ensures that when the detected noise exceeds a noise threshold, the rotation angle of the first louver 3 of each panel 2 can be individually controlled, allowing each panel 2 to have a different angle, thus enhancing the noise reduction effect. For example, if the noise threshold is set to 50 decibels, when the actual detected noise is below 50 decibels, the louver structure of each panel 2 remains closed. When the actual detected noise is between 50 and 65 decibels, the first louver 3 of two panels 2 is rotated by 15°, while the louver structures of the other panels remain closed. When the actual detected noise is greater than 65 decibels, the first louver 3 of the remaining two panels 2 is rotated by 10°, while the louver structures of the other panels remain in their previous state. Thus, by using different shapes of the first 100-leaf strip 3, noise can be fully blocked and reduced.

[0064] Similarly, with a wind force threshold set to level 7, when the detected crosswind force is less than level 7, the first louver 3 at 1 / 4 of the height of the louver structure of the windbreak and sound insulation housing 1 remains open, while the other louver structures of the windbreak and sound insulation housing 1 remain closed. When the detected crosswind force is greater than level 7, the second louver 4 within 1 / 3 of the height range is rotated by 15°, so that the upper space of each of the first louvers 3 in this part is open. This alleviates the external force of the crosswind on the windbreak and sound insulation housing 1 while maintaining the noise reduction effect.

[0065] Therefore, the multifunctional sound barrier device of the present invention can not only fully guarantee the sound insulation effect, but also ensure the safety protection of its structure, realizing multifunctional use and the effect is far superior to the sound barrier devices in the prior art.

[0066] Example 3

[0067] See Figure 1-3 A multifunctional sound barrier device for roads and bridges mainly includes a windproof and sound-insulating shell 1 and multiple interconnected sound-absorbing and noise-reducing panels 2. The windproof and sound-insulating shell 1 has an overall arc-shaped structure.

[0068] Both the windproof and soundproof housing 1 and the sound-absorbing and noise-reducing panel 2 have louver structures. The louver structure of the windproof and soundproof housing 1 includes multiple parallel first louver strips 3, and the louver structure of the sound-absorbing and noise-reducing panel 2 includes multiple parallel second louver strips 4. The first louver strips 3 are arc-shaped, and the second louver strips 4 are triangular. Both the first louver strips 3 and the second louver strips 4 can be rotated at a certain angle as needed.

[0069] The multiple interconnected sound-absorbing and noise-reducing panels 2 are arranged in order of tilt from top to bottom on the inner side of the windbreak and sound insulation shell 1 facing the road and bridge direction, and the upper and lower ends of adjacent sound-absorbing and noise-reducing panels 2 are connected to each other. The uppermost sound-absorbing and noise-reducing panel 2 is connected to the top of the windbreak and sound insulation shell 1, and the lowermost sound-absorbing and noise-reducing panel 2 is connected to the bottom of the windbreak and sound insulation shell 1.

[0070] The surfaces of the first louver 3 and the second louver 4 are both covered with sound-absorbing and sound-insulating material, and the surface of the sound-absorbing and sound-insulating material is provided with a recessed structure of varying depths.

[0071] A dust-collecting net is provided on the inner surface of the windproof and soundproof housing 1.

[0072] The overall curvature of each of the first 100-leaf strips 3 is not exactly the same, and they are arranged continuously, so that when the whole is completely closed, it can ensure the formation of a closed arc-shaped windproof and soundproof shell 1.

[0073] The first louver 3 of the louver structure of the windproof and soundproof housing 1 can be kept in a normally open state, that is, the windproof and soundproof housing 1 in this range has gaps, thereby forming a negative pressure in the inner space of the windproof and soundproof housing 1 by the action of external wind force, so that the dust generated on the road and bridge is deposited in the recessed structure and the dust collection net, thereby achieving a stronger dust collection effect; the range is from the top of the windproof and soundproof housing 1 downwards and accounts for 1 / 4 of the overall height of the windproof and soundproof housing 1.

[0074] The recessed structure can take the form of a rhombus, triangle, square, or elongated groove, and dust generated on roads and bridges can be deposited inside it.

[0075] The first louver 3 and the second louver 4 can both rotate at a certain angle as needed. This means that the rotation of the first louver 3 and the second louver 4 is controlled according to the magnitude of the external wind force and / or the noise level of the road and bridge, so that the corresponding louver structure can be opened at a certain angle and / or completely closed. In this embodiment, the first louver 3 and the second louver 4 are rotated by 5°, so that the corresponding louver structure is opened.

[0076] The multifunctional sound barrier device is also equipped with a control module, a first motor, a second motor, a first louver actuator, a second louver actuator, a noise sensor, and a wind sensor. The control module has preset noise thresholds and wind thresholds. The first motor drives the first louver actuator to rotate the first louver slat 3, and the second motor drives the second louver actuator to rotate the second louver slat 4. The control module can control the first motor and the second motor individually or simultaneously.

[0077] A wind sensor is installed on the outer side of the windproof and soundproof housing 1, and a noise sensor is installed on the sound-absorbing and noise-reducing plate 2; both the first louver actuator and the second louver actuator are linkage-type structures.

[0078] A water guide channel is provided at the connection between the inner bottom of the windproof and soundproof housing 1 and the road and bridge. The top of the water guide channel is covered with a cover plate with multiple through holes. The bottom of the water guide channel is connected to multiple drainage pipes, and the other end of the drainage pipes can be connected to the rainwater drainage pipes of the road and bridge.

[0079] The top of the windproof and soundproof housing 1 is equipped with a solar charging module to provide energy for the operation and lighting of the entire multifunctional sound barrier device; the top frame and side frame of the windproof and soundproof housing 1, as well as the top and bottom frames and side frames of the sound-absorbing and noise-reducing panel 2, are all equipped with lighting lamps.

[0080] The inner side of the windbreak and sound insulation shell 1, the outer side facing away from the road and bridge, and the surface of the sound-absorbing and noise-reducing panel 2 are all coated with an anti-reflective layer. This reduces light pollution to the outside world caused by the reflection from the outer side of the windbreak and sound insulation shell 1.

[0081] In addition, to further improve the technical effect of the present invention, in this embodiment, the sound-absorbing and noise-reducing plate 2 is provided with 5 pieces.

[0082] The sound-absorbing and sound-insulating material comprises the following components in parts by weight: 200 parts calcium silicate, 150 parts calcium aluminate, 220 parts orthoclase powder, 100 parts sodium silicate, 10 parts polyester, 60 parts sound-absorbing cotton fiber, and 100 parts latex. The orthoclase powder has a particle size of 2-4 mm, the polyester has a length of 10-12 mm, and the sound-absorbing cotton fiber has a length of 15-20 mm.

[0083] Tests have shown that the noise reduction performance of the sound-absorbing and sound-insulating material of this invention exceeds the national Class I standard, with a sound absorption coefficient of 0.89 and a noise reduction coefficient (NRC) of 0.9. This effectively shields pollution noise and prevents the reflection of sunlight, thus avoiding glare for the driver during driving, preventing traffic accidents, and improving driving safety.

[0084] The anti-reflective layer comprises a top layer, a middle layer, and a bottom layer, arranged from top to bottom. The top layer is a polarizing film, the middle layer is a pigment black matrix layer, and the bottom layer is a gray thin film layer. The layers are bonded together with adhesive. This structural design further ensures the anti-reflective effect, minimizing light pollution.

[0085] As can be seen from the above embodiments, the sound barrier device of the present invention has multiple functions such as automatic adjustment of sound insulation and noise reduction, dust absorption, anti-reflection, wind blocking, and lighting, which meet the diverse needs of roads. This multifunctional sound barrier device has rich functions, strong adaptability to the environment, simple process, and low operation and maintenance costs.

[0086] This invention can adjust the rotation angle of the first and second louvers according to the noise and wind force, thereby changing the shape of the windbreak and sound insulation shell and the sound-absorbing and noise-reducing panel, achieving excellent effects in strengthening noise isolation and blocking crosswinds, further improving driving safety and reducing noise pollution on roads and bridges.
