Description

Technical Field

[0001] This invention relates to the field of road and bridge construction technology, and in particular, to a sound barrier. Background Technology

[0002] With the acceleration of urbanization and the continuous improvement of transportation infrastructure, transportation networks such as highways, urban viaducts, and railways are becoming increasingly developed. However, traffic noise pollution is also becoming more and more prominent. In order to effectively reduce traffic noise, sound barriers have become a common solution and are widely used in bridges, roads, and railways.

[0003] Traditional sound barriers typically use materials such as concrete, metal panels, or transparent plastic panels. While they offer some noise reduction, they also have several drawbacks. For example, concrete sound barriers, although sturdy and durable, are heavy, resulting in high installation and maintenance costs; metal panel sound barriers, while lightweight, have poor corrosion resistance and are prone to rusting in harsh environments; and transparent plastic panel sound barriers, while offering good light transmission, have low strength and are prone to aging. Furthermore, traditional sound barriers have a relatively limited function, focusing solely on noise reduction and failing to fully utilize their structural advantages to achieve more additional functionalities. Summary of the Invention

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a sound barrier.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0006] A sound barrier includes: columns arranged at intervals along the left-right direction, with mounting grooves on opposite sides of two adjacent columns; a foam aluminum screen body disposed between two adjacent columns, with its left and right sides respectively embedded in corresponding mounting grooves; a capping component fixedly installed on the upper end of the columns, with its bottom embedded in the mounting groove and its top having an inclined shielding portion extending upward and forward, the top of which is equipped with an auxiliary lighting lamp; and a photovoltaic panel installed on the rear side of the inclined shielding portion.

[0007] Furthermore, the rear side of the inclined shielding part is provided with a mounting frame, and the mounting frame is provided with a mounting slot for the edge of the photovoltaic panel to be embedded.

[0008] Furthermore, it also includes pre-tightening limiting components and adjusting screws. The pre-tightening limiting components are located on the left and right sides of the aluminum foam screen body. The pre-tightening limiting components are movably installed on the upper end of the corresponding mounting groove. The adjusting screws are threaded to the front side wall of the mounting groove and are used to push the pre-tightening limiting components to contact the aluminum foam screen body so that the rear side of the aluminum foam screen body is tightly attached to the rear side wall of the mounting groove and the aluminum foam screen body is clamped by the pre-tightening limiting components on both sides.

[0009] Furthermore, the bottom of the capping component is provided with a mounting block embedded in the mounting groove, and the mounting block is provided with a limiting hole for the adjusting screw to pass through.

[0010] Furthermore, the left and right edges of the front side of the aluminum foam screen are provided with first inclined surfaces, and the first inclined surfaces on the left and right sides converge forward; the pre-tightening limiting member is provided with a first contact surface that fits with the first inclined surface.

[0011] Furthermore, the bottom of the capping component is provided with a limiting block embedded in the mounting groove, the bottom of the limiting block is provided with a second inclined surface corresponding to the first inclined surface, and the limiting block is provided with a limiting notch above the second inclined surface; the first contact surface is partially in contact with the first inclined surface and partially in contact with the second inclined surface.

[0012] Furthermore, the top of the pre-tightening limiting member is provided with a limiting protrusion embedded in the limiting notch.

[0013] Furthermore, the rear sidewall of the limiting block is fitted with the rear sidewall of the mounting groove; the front sidewall of the mounting block is fitted with the front sidewall of the mounting groove.

[0014] Furthermore, the side wall of the mounting groove is provided with a first guide rail, and the pre-tightening limiting member is provided with a first sliding groove adapted to the first guide rail.

[0015] Furthermore, the top of the inclined shielding part is provided with a horizontal mounting strip, and the auxiliary lighting lamp is installed at the bottom of the horizontal mounting strip.

[0016] Furthermore, the top of the inclined shielding part is provided with a horizontal mounting strip, and the auxiliary lighting lamp is installed at the bottom of the horizontal mounting strip.

[0017] The present invention has the following beneficial effects:

[0018] The use of aluminum foam shielding not only provides excellent sound absorption performance but also achieves a lightweight design, reducing the overall weight of the sound barrier. Compared with traditional concrete or metal plate sound barriers, aluminum foam shielding reduces installation and maintenance costs while ensuring noise reduction, improving the economic efficiency and practicality of the sound barrier. The inclined shielding design of the capping component not only increases the sound insulation range of the sound barrier but also integrates auxiliary lighting and photovoltaic panels. The auxiliary lighting provides nighttime illumination for the bridge area, and the installation of photovoltaic panels allows the sound barrier to collect solar energy and convert it into electricity to power the auxiliary lighting or other equipment, reducing dependence on external power and achieving energy conservation and emission reduction. The multi-functional integrated design not only enhances the practicality of the sound barrier but also achieves efficient resource utilization. The aluminum foam shielding is embedded in the mounting groove of the column, and the fixed installation of the capping component and the sealing effect of the aluminum foam shielding make the installation process of the sound barrier simpler and faster. At the same time, the modular design of each component facilitates maintenance and replacement.

[0045] Please refer to Figure 1 , Figure 2 and Figure 3A preferred embodiment of the present invention provides a sound barrier comprising a column 100, a foam aluminum screen body 200, a capping component 300, and a photovoltaic panel 400.

[0046] The columns 100 are arranged at intervals in the left-right direction, and mounting grooves 110 are provided on the opposite sides of two adjacent columns 100. In order to achieve the versatility of the columns 100 and facilitate mass production, mounting grooves 110 are provided on both the left and right sides of the columns 100.

[0047] The aluminum foam screen 200 is located between two adjacent columns 100, and the left and right sides of the aluminum foam screen 200 are respectively embedded in the corresponding mounting grooves 110.

[0048] The capping component 300 is fixedly installed on the upper end of the column 100. The bottom of the capping component 300 is embedded in the mounting groove 110. The top of the capping component 300 is provided with an inclined shielding part 310 that extends upward and forward. An auxiliary lighting lamp 311 is installed on the top of the inclined shielding part 310.

[0049] The photovoltaic panel 400 is installed on the rear side of the inclined shading part 310. Understandably, a battery is usually configured to store the electrical energy converted by the photovoltaic panel 400, thereby powering the auxiliary lighting 311. Of course, the auxiliary lighting 311 can also be connected to an external power supply line to provide power when the battery power is insufficient.

[0050] In a preferred embodiment of the present invention, a sound barrier employing a foamed aluminum screen body 200 not only provides excellent sound absorption performance but also achieves a lightweight design, reducing the overall weight of the sound barrier. Compared with traditional concrete or metal plate sound barriers, the foamed aluminum screen body reduces installation and maintenance costs while ensuring noise reduction effects, thus improving the economic efficiency and practicality of the sound barrier. The inclined shielding portion 310 of the capping component 300 not only increases the sound insulation coverage range of the sound barrier but also integrates auxiliary lighting 311 and photovoltaic panels 400. The auxiliary lighting 311 provides nighttime illumination for the bridge area, and the installation of photovoltaic panels 400 allows the sound barrier to collect solar energy and convert it into electrical energy to power the auxiliary lighting or other equipment, reducing dependence on external power and achieving energy conservation and emission reduction. The multi-functional integrated design not only enhances the practicality of the sound barrier but also achieves efficient resource utilization. The foamed aluminum screen body 200 is embedded in the mounting groove 110 of the column 100, and the fixed installation of the capping component 300 and the capping effect on the foamed aluminum screen body 200 make the installation process of the sound barrier simpler and faster. Meanwhile, the modular design of each component facilitates maintenance and replacement.

[0051] Reference Figure 11In some embodiments of the present invention, a mounting frame 320 is provided on the rear side of the inclined shielding portion 310. The mounting frame 320 has an insertion slot 321 for the edge of the photovoltaic panel 400 to be inserted. The upper part of the insertion slot 321 is open to facilitate the insertion of the photovoltaic panel 400 into the insertion slot 321. Furthermore, for fixed installation, the mounting frame 320 and the photovoltaic panel 400 have corresponding holes for connection and fixation by fasteners. The insertion slot 321 provides a stable mounting structure for the photovoltaic panel 400, and the embedded structure of the insertion slot 321 improves the installation accuracy and stability of the photovoltaic panel 400.

[0052] Reference Figure 4 , Figure 5 and Figure 6 In some embodiments of the present invention, a pre-tightening limiting member 500 and an adjusting screw 600 are further included. The pre-tightening limiting member 500 is disposed on the left and right sides of the aluminum foam screen 200 and is movably installed on the upper end of the corresponding mounting groove 110. The adjusting screw 600 is threaded to the front side wall of the mounting groove 110 and is used to push the pre-tightening limiting member 500 into contact with the aluminum foam screen 200, so that the rear side of the aluminum foam screen 200 is tightly attached to the rear side wall of the mounting groove 110 and the aluminum foam screen 200 is clamped by the pre-tightening limiting members 500 on both sides. Specifically, the front side wall of the mounting groove 110 is provided with a first threaded hole 112 for the adjusting screw 600 to be threaded into. By pushing the pre-tightening limiting member 500 into contact with the aluminum foam screen 200 by the adjusting screw 600, the screen is securely clamped. The adjusting screw 600 can be turned to adjust its position to push the pre-tightening limiter 500 to move backward. The pre-tightening limiter 500 makes the rear side of the foam aluminum screen 200 fit tightly against the rear side wall of the mounting groove 110, eliminating gaps in the front-to-back direction. The foam aluminum screen 200 is also clamped by the pre-tightening limiters 500 on both sides, thereby eliminating gaps in the left-to-right direction. This eliminates installation gaps in multiple directions for the foam aluminum screen 200, ensuring that the foam aluminum screen 200 is tightly connected to the column 100 after installation. This effectively avoids screen loosening and noise caused by vehicle vibration or external force, improving the stability and service life of the sound barrier.

[0053] In a further embodiment of the present invention, the bottom of the capping member 300 is provided with a mounting block 330 embedded in the mounting groove 110, and the mounting block 330 is provided with a limiting hole 331 for the adjusting screw 600 to pass through. The main function of the adjusting screw 600 is to push the pre-tightening limiting member 500 to move and clamp the foam aluminum screen body 200. The capping member 300 uses the adjusting screw 600 passing through the limiting hole 331 to achieve limiting and fixing, so that the adjusting screw 600 has two different functions, making the structure more ingenious and the installation and disassembly simpler.

[0054] Reference Figure 4 and Figure 6In a further embodiment of the present invention, the left and right edges of the front side of the aluminum foam screen body 200 are provided with first inclined surfaces 210, and the first inclined surfaces 210 on the left and right sides converge forward; the pre-tightening limiting member 500 is provided with a first contact surface 510 that fits with the first inclined surface 210. The first inclined surface 210 on the front side of the aluminum foam screen 200 combines with the first contact surface 510 on the pre-tightening limiting member 500. When the first contact surface 510 and the first inclined surface 210 are in close contact, the aluminum foam screen 200 will be pushed to move backward and fit tightly against the rear side wall of the mounting groove 110. At the same time, the aluminum foam screen 200 also tends to move towards the pre-tightening limiting member 500 on the other side, and the pre-tightening limiting member 500 on the other side will also press the aluminum foam screen 200, so that it is clamped left and right by the pre-tightening limiting members 500 on both sides, thereby achieving pre-tightening and gap elimination in two directions. Due to the characteristics of the first inclined surface 210, the greater the forward force of the pre-tightening limiting member 500, the better the pre-tightening effect. The pre-tightening can be adjusted according to actual needs.

[0055] In a further embodiment of the present invention, the bottom of the capping member 300 is provided with a limiting block 340 embedded in the mounting groove 110, and the bottom of the limiting block 340 is provided with a second inclined surface 341 corresponding to the first inclined surface 210. The first contact surface 510 is partially in contact with the first inclined surface 210 and partially in contact with the second inclined surface 341; the first contact surface 510 not only partially in contact with the first inclined surface 210 to achieve clamping and fixing of the foam aluminum screen body 200, but also partially in contact with the second inclined surface 341, cooperating with the rear side wall of the mounting groove 110 to simultaneously achieve clamping and fixing of the limiting block 340, thereby achieving multi-position fixing of the capping member 300, avoiding the capping member 300 being limited and fixed only by the adjusting screw 600 passing through the limiting hole 331, and improving the stability of the installation and fixing of the capping member 300.

[0056] Reference Figure 7 and Figure 8 The limiting block 340 has a limiting notch 342 above the second inclined surface 341, and the top of the pre-tightening limiting member 500 has a limiting protrusion 520 that is embedded in the limiting notch 342. By using the limiting protrusion 520 embedded in the limiting notch 342, the limiting block 340 is further vertically limited and fixed, further improving the installation accuracy and stability of the capping member 300. It is understood that, to reduce installation gaps, the bottom surface of the limiting block 340 is fitted with or clamped to the upper surface of the uppermost foam aluminum screen 200 using a rubber pad. For ease of disassembly, such as... Figure 10 As shown, after installation, the front side of the pre-tightening limiting member 500 and the mounting block 330 have a gap larger than the protrusion size of the limiting protrusion 520. This allows sufficient space on the front side of the pre-tightening limiting member 500 to allow it to move forward during disassembly, causing the limiting protrusion 520 to disengage from the limiting notch 342 and releasing the limiting lock on the capping member 300.

[0057] Reference Figure 10 In a further embodiment of the present invention, the rear sidewall of the limiting block 340 is fitted with the rear sidewall of the mounting groove 110; the front sidewall of the mounting block 330 is fitted with the front sidewall of the mounting groove 110. These two sets of fitted sidewalls further optimize the installation accuracy and stability of the capping component 300. This allows the overturning moment of the capping component 300 to be partially dissipated through the front and rear sidewalls of the mounting groove 110, avoiding stress concentration, improving the overall structural strength of the sound barrier, and reducing vibration and loosening problems caused by installation gaps.

[0058] Reference Figure 9 In a further embodiment of the present invention, the side wall of the mounting groove 110 is provided with a first guide rail 111, and the pre-tightening limiting member 500 is provided with a first sliding groove 530 adapted to the first guide rail 111. This allows the pre-tightening limiting member 500 to slide smoothly along the first guide rail 111, improving the installation accuracy of the pre-tightening limiting member 500. Furthermore, the limiting effect of the first sliding groove 530 ensures the stability of the pre-tightening limiting member 500 during adjustment. It is understood that, for ease of installation, the rear end of the first guide rail 111 and the rear side wall of the mounting groove 110 have a gap for the pre-tightening limiting member 500 to embed. This gap is sufficient for the first sliding groove 530 to align with the first guide rail 111 after the pre-tightening limiting member 500 is embedded. Then, the pre-tightening limiting member 500 moves to allow the first guide rail 111 to embed into the first sliding groove 530, thereby achieving installation. It is understood that the mounting block 330 will avoid the first guide rail 111 when embedding into the mounting groove 110.

[0059] It is understandable that, in order to clamp and limit the upper position of the top muffler structure 700, the pre-tightening limiting member 500 is provided with a first pressure plate 540 on its side to press the muffler structure 700. A first limiting groove 541 is also provided between the first pressure plate 540 and the pre-tightening limiting member 500 for the limiting strip 710 of the muffler structure 700 to be inserted.

[0060] In some embodiments of the present invention, the top of the inclined shielding part 310 is provided with a horizontal mounting strip 350, and the auxiliary lighting lamp 311 is mounted at the bottom of the horizontal mounting strip 350. The horizontal mounting strip 350 shields the auxiliary lighting lamp 311 and provides it with an installation position. The lamp housing of the auxiliary lighting lamp 311 and the horizontal mounting strip 350 can be provided with corresponding holes for connection and fixation by fasteners.

[0061] To further improve the tightness of the connection between structures, a filler sleeve 800 is sandwiched between the left and right sides of the aluminum foam screen 200 and the inner wall of the mounting groove 110. The upper end of the filler sleeve 800 also wraps around the limiting block 340. This enhances the contact tightness between the limiting block 340 and the aluminum foam screen 200 and the column 100, which not only improves the noise reduction effect of the sound barrier, but also reduces loosening and noise caused by vibration during use through the buffering effect of the filler sleeve 800, further improving the stability of the sound barrier. The sound-absorbing structure can be made of sponge or polyethylene closed-cell foam material, which is lightweight and further enhances the sound absorption and insulation effect. The filler sleeve and filler pad can be made of rubber material.

[0062] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
