[0041] Please refer to Figure 1 and Figure 2 , a traffic road photovoltaic sound insulation wall in a preferred embodiment provided by the present invention includes a base 100, vertical columns 200, connecting members 300, photovoltaic modules 400, sound insulation boards 500 and fasteners 600.

[0042] The base 100 is fixedly installed on the road pier 101; the base 100 is fixed to the road pier 101 through fasteners.

[0043] The bottom of the vertical column 200 is fixed to the base 100, and the vertical columns 200 are arranged at intervals in the left - right direction. The left and right ends of the connecting member 300 are respectively connected to two adjacent vertical columns 200, and the connecting members 300 are arranged vertically. Specifically, each connecting member 300 is disposed at the front side position between two adjacent vertical columns 200 on the left and right.

[0044] The photovoltaic module 400 is connected to the front side of the connecting member 300, and the photovoltaic modules 400 are arranged vertically. The photovoltaic module 400 includes a photovoltaic panel and a frame on the periphery of the photovoltaic panel.

The sound insulation board 500 can be made of materials such as galvanized steel plates, aluminum plates, and aluminum alloy perforated plates, and usually filled with sound - absorbing materials inside to improve the sound insulation effect.

[0046] The fastener 600 is connected to the connecting member 300, and the fastener 600 is used to fix the photovoltaic module 400 and the sound insulation board 500.

[0047] A traffic road photovoltaic sound insulation wall provided by the present invention realizes the integrated installation of a photovoltaic module 400 and a sound insulation board 500 through the combined design of a base 100, vertical columns 200, and connectors 300. The vertical columns 200 are arranged at intervals in the left - right direction and are fixed to the base 100 at the bottom, providing stable support for the photovoltaic module 400 and the sound insulation board 500. The left and right ends of the connector 300 are respectively connected to two adjacent vertical columns 200, further enhancing the structural stability. The present invention makes full use of the space resources on the side of the traffic road and integrates the photovoltaic module 400 and the sound insulation board 500 into the same structure. The photovoltaic module 400 is connected to the front side of the connector 300 and is arranged vertically, which can not only effectively utilize sunlight for power generation but also reduce traffic noise. The sound insulation board 500 is connected to the rear side of the connector 300, further enhancing the sound insulation effect. The fastener 600 can simultaneously install and fix the photovoltaic module 400 and the sound insulation board 500, so that the photovoltaic module 400 and the sound insulation board 500 do not need to be separately provided with fasteners for installation and fixation, which can effectively reduce the number of fasteners and simplify the installation steps.

[0048] Referring to Figures 3 to 7 , in some embodiments of the present invention, the connector 300 has an opening groove 310 with an upper opening, and a positioning slot 311 is provided on the rear side wall of the opening groove 310; the upper end of the sound insulation board 500 is provided with an extension part 510 extending forward, and a downward extension part 520 is provided at the front end of the extension part 510. The downward extension part 520 is embedded in the opening groove 310 and a protrusion is provided on the rear side and a positioning part 530 for embedding in the positioning slot 311. During installation, the downward extension part 520 is embedded in the opening groove 310 to achieve partial support and positioning effects, and then the positioning part 530 is pushed to be embedded in the positioning slot 311, realizing the rapid positioning of the sound insulation board 500. In cooperation with the fastener 600, rapid positioning and fixation are achieved, facilitating rapid installation. The positioning part 530 is embedded in the positioning slot 311, ensuring the stability and accuracy of the sound insulation board 500 during the installation process. It not only improves the installation efficiency but also reduces the installation error caused by inaccurate positioning.

[0049] Referring to Figure 8 and Figure 9 , in a further embodiment of the present invention, the upper and lower surfaces of the positioning part 530 are in contact with the upper and lower inner walls of the positioning slot 311, and the positioning part 530 is provided with an abutting block 531 protruding backward, and the abutting block 531 is in contact with the rear side wall of the positioning slot 311. Through the contact between the abutting block 531 and the rear side wall of the positioning slot 311, the positioning and fixing effects of the sound insulation board 500 are further enhanced. The upper and lower surfaces of the positioning part 530 are in contact with the upper and lower inner walls of the positioning slot 311, ensuring the vertical stability of the sound insulation board 500.

[0050] Referring to Figures 3 to 7, in a further embodiment of the present invention, the sound insulation boards 500 are arranged vertically and spliced; a limiting groove 521 is provided on the front side of the downward extension part 520, a front extension part 540 is provided at the lower end of the sound insulation board 500, a fitting board 541 extending downward is provided at the front end of the front extension part 540, and a positioning protrusion 542 is provided on the rear side of the fitting board 541; the positioning protrusion 542 of the upper sound insulation board 500 is embedded in the limiting groove 521 of the adjacent lower sound insulation board 500, the bottom surface of the front extension part 540 of the upper sound insulation board 500 is attached to the extension part 510 of the adjacent lower sound insulation board 500, and the fitting board 541 of the upper sound insulation board 500 is attached to the downward extension part 520 of the adjacent lower sound insulation board 500. The vertical arrangement and splicing of the sound insulation boards 500, through the cooperation of the limiting groove 521 and the positioning protrusion 542, realize the rapid splicing and fixation between the sound insulation boards 500, and through the attachment of the front extension part 540 and the extension part 510, and the attachment of the fitting board 541 and the downward extension part 520, realize the attachment and abutment positioning during the installation of the upper and lower sound insulation boards 500, ensure the close attachment between the sound insulation boards 500, and the fastener 600 can act on the fitting board 541 to realize the pressing of the fitting board 541 and the downward extension part 520, thereby realizing the connection stability at the splicing position of the two sound insulation boards 500. The splicing design reduces the use of fasteners, further simplifies the installation steps, improves the installation efficiency of the sound insulation boards 500, and also ensures the close attachment between the sound insulation boards 500 through the structures of the front extension part 540 and the fitting board 541, enhancing the sound insulation effect.

[0051] Referring to Figure 7 , in a further embodiment of the present invention, the horizontal distance between the sound insulation board 500 and the connecting member 300 is greater than the horizontal protrusion size of the positioning protrusion 542 and the horizontal protrusion size of the positioning part 530. This ensures the smooth embedding and fixation of the positioning protrusion 542 and the positioning part 530. Thus, there is sufficient forward movement distance for the positioning part 530 to bypass the top wall of the positioning card slot 311 and the positioning protrusion 542 to bypass the top wall of the limiting groove 521, improving the installation convenience. Also, through the reasonable spacing setting, the installation difficulties caused by component interference are reduced.

[0052] Referring to Figure 7 , in a further embodiment of the present invention, the upper surface of the abutting block 531 is lower than the upper surface of the positioning part 530, and the lower surface is higher than the lower surface of the positioning part 530, so that the abutting block 531 avoids the upper and lower corners of the rear side wall of the positioning card slot 311. Usually, the positioning card slot 311 is formed by bending a plate, and arcs will be formed at the corners. The abutting block 531 avoiding the upper and lower corners of the rear side wall of the positioning card slot 311 can make the abutting block 531 have close contact with the rear side wall of the positioning card slot 311, so that the depth of the positioning part 530 embedded in the positioning card slot 311 is sufficient, achieving the effect of stable positioning.

[0053] Referring to Figures 3 to 7, in a further embodiment of the present invention, it further includes a fixing member 700, and the fixing member 700 and the connecting member 300 are arranged vertically corresponding to each other; the fixing member 700 includes a connecting block 710 and a pressing block 720, and the connecting block 710 and the connecting member 300 are provided with corresponding holes to be connected by a fastener 600; the pressing block 720 is connected to the front end of the connecting block 710 and protrudes vertically from the connecting block 710, and a slot 730 is formed among the pressing block 720, the connecting block 710 and the connecting member 300; the bottom and top of the photovoltaic module 400 are embedded into the corresponding slots 730 and are pressed by the pressing block 720 to be in fit with the connecting member 300; a part of the fastener 600 extends into the opening slot 310 to press the downward extension part 520 or the fitting plate 541, ensuring the fixing effect of the sound insulation board 500. It can be understood that if the fastener 600 correspondingly presses the splicing position of two sound insulation boards 500, the fastener 600 will press the fitting plate 541. Of course, at this time, the fitting plate 541 is in fit with the downward extension part 520, and at the same time, the downward extension part 520 will also be pressed, so that the positioning part 530 is stably embedded into the positioning card slot 311 to realize limit, and the positioning protrusion 542 is embedded into the limit groove 521 of the adjacent lower sound insulation board 500 to realize the stable splicing and positioning of the sound insulation board 500. When the fastener 600 corresponds to the upper end of the uppermost sound insulation board 500, the fastener 600 will press the downward extension part 520. When the fastener 600 corresponds to the lower end of the lowermost sound insulation board 500, the fastener 600 will press the fitting plate 541. In order to install and fix the photovoltaic module 400 and the sound insulation board 500 by using the connecting member 300 at the same time, the photovoltaic module 400 and the sound insulation board 500 are both arranged vertically, and the top and bottom of each photovoltaic module 400 and sound insulation board 500 respectively correspond to a connecting member 300 for connection and cooperation, so as to realize the installation and fixation of the top and bottom of the photovoltaic module 400 and the sound insulation board 500. It can be understood that the splicing positions of two adjacent upper and lower photovoltaic modules 400 and the splicing positions of two adjacent upper and lower sound insulation boards 500 will share a connecting member 300. The fixing member 700 and the formed slot 730 realize the support and limit of the photovoltaic module 400, and the connection and fixation of the fixing member 700 can realize the fixation of the photovoltaic module 400 while reducing the installation gap of the photovoltaic module 400, integrating and realizing multiple functions, simplifying the installation steps, reducing the installation time and labor cost, and improving the construction efficiency.Generally, there will be a certain clearance from the ground at the bottom of the photovoltaic module 400. In order to make the sound insulation board 500, the connecting piece 300 and the photovoltaic module 400 arranged vertically in correspondence, there will also be a certain clearance from the ground at the bottom of the lowermost sound insulation board 500. In order to increase the sound insulation effect, a bottom sealing plate 800 will be installed below the lowermost sound insulation board 500. In order to simplify the installation of the bottom sealing plate 800 and also to avoid the lack of vertical limit at the lower end of the lowermost sound insulation board 500 and the suspension of the fitting plate 541 being resisted by the fastener 600, the upper end of the bottom sealing plate 800 is provided with an extension part 510, a downward extension part 520, a positioning part 530 and a limit groove 521, that is, the upper end structure of the bottom sealing plate 800 is the same as the upper end structure of the sound insulation board 500, so as to achieve the effect of similar upper and lower limit splicing of the sound insulation board 500. Not only the limit fixation of the bottom sealing plate 800 is realized, but secondly, the limit of the lowermost sound insulation board 500 can also be realized by the positioning protrusion 542 of the lowermost sound insulation board 500 being embedded in the limit groove 521 of the bottom sealing plate 800.

[0054] Referring to Figures 3 to 7 , in a further embodiment of the present invention, the connecting piece 300 includes a bottom plate 320 and side plates 330 provided on the front and rear sides of the bottom plate 320. The opening groove 310 is defined by the bottom plate 320 and the side plates 330 on both sides. The upper end of the rear side plate 330 is provided with a folded edge 340 that is turned inward. The positioning card slot 311 is defined by the folded edge 340, the rear side plate 330 and the bottom plate 320. The opening groove 310 is defined by the bottom plate 320 and the side plates 330 on both sides. The folded edge 340 not only defines the positioning card slot 311, but also further enhances the structural strength of the side plate 330. And the folded edge 340 can prevent the sharp corners at the upper end edge of the side plate 330 from contacting the photovoltaic module.

[0055] Referring to Figures 3 to 7 , in a further embodiment of the present invention, the connecting block 710 is provided with a through hole 711, the front side plate 330 is provided with a through hole 331, and a nut 332 aligned with the through hole 331 is fixedly provided on the rear side surface of the front side plate 330. The fastener 600 is a bolt threadedly connected to the nut 332. The bolt head of the bolt presses the connecting block 710, and the end of the bolt extends into the opening groove 310 and presses the downward extension part 520 or the fitting plate 541. By using the through hole 711 and the through hole 331, through the threaded connection of the nut 332 and the bolt, the firm connection between the fixing member 700 and the connecting piece 300 is realized. And the bolt head pressing the connecting block 710 can drive the pressing block 720 to press the photovoltaic module 400. The end of the bolt extends into the opening groove 310 to further press the downward extension part 520 and the fitting plate 541, ensuring the fixing effect of the sound insulation board 500, so as to achieve multiple purposes and further realize the fixing of the sound insulation board 500.

[0056] Referring to Figures 3 to 7, in a further embodiment of the present invention, a support plate 210 is provided on the front side of the vertical column 200; the bottom plate 320 is fixedly connected to the support plate 210, and both ends of the connecting member 300 are respectively supported on the support plates 210 of the left and right vertical columns 200. It can be understood that the arrangement number and position of the support plate 210 and the connecting member 300 are correspondingly set. The rear side plate 330 is attached to the front side of the vertical column 200, and the auxiliary positioning during the installation process is realized by attaching the rear side plate 330 to the front side of the vertical column 200. The front side plate 330 is connected to the fixing member 700; an auxiliary positioning plate 220 is provided on the front side of the vertical column 200, the auxiliary positioning plate 220 is provided with a positioning post 221 extending upward, a hanging plate 410 is connected to the rear side of the photovoltaic module 400, the hanging plate 410 is provided with a positioning hole 411 adapted to the positioning post 221, the bottom surface of the hanging plate 410 is attached to the auxiliary positioning plate 220, and the positioning post 221 is embedded in the positioning hole 411. Through the cooperation of the positioning post 221 and the hanging plate 410, the rapid positioning and pre-fixing of the photovoltaic module 400 are realized. Thus, during installation, the hanging plate 410 can be first supported on the auxiliary positioning plate 220, and then the photovoltaic module 400 is temporarily positioned and supported by embedding the positioning post 221 into the positioning hole 411, and then the fixing member 700 is installed, which can optimize the installation steps and avoid the unstable position or dropping of the photovoltaic module 400 during installation. Moreover, the hanging plate 410 and the positioning hole 411 on the rear side of the photovoltaic module 400 realize the precise positioning of the photovoltaic module 400 and reduce the installation error caused by inaccurate positioning.

[0057] To improve the structural strength of the support plate 210 and the auxiliary positioning plate 220, reinforcing ribs can be provided at the bottom of the support plate 210 and the auxiliary positioning plate 220 to enhance the structural strength and improve its stability and durability during long-term use.

[0058] It can be understood that, in order to achieve stable installation, at least two fixing members 700 are provided on each connecting member 300, so as to support the photovoltaic module 400 at multiple positions. As Figure 1 shown, the vertical columns 200 are arranged at intervals in the left-right direction, and there are three groups of fixing members 700 and connecting members 300 arranged vertically, and there are two groups of photovoltaic modules 400 arranged vertically. The bottom of the photovoltaic module 400 is connected to the lower fixing member 700, and the top is connected to the upper fixing member 700. Two fixing members 700 are provided on each connecting member 300, so that one photovoltaic module 400 corresponds to four fixing members 700 to realize multi-position connection and limit fixation. Moreover, the adjacent sides of the adjacent photovoltaic modules 400 share two fixing members 700, which further simplifies the number of components and the installation steps.

[0059] Referring to Figure 5 and Figure 7, in a further embodiment of the present invention, the pressing block 720 of the fixing member 700 at the middle position between two photovoltaic modules 400 is provided with two, and the connecting blocks 710 protrude vertically upward and downward respectively. Two pressing blocks 720 of the fixing member 700 on the connecting member 300 at the middle position between two photovoltaic modules 400 are provided, which realizes the fixation of the adjacent sides of the upper and lower adjacent photovoltaic modules 400, thus reducing the use of components. It can be understood that the fixing member 700 on the lowermost connecting member 300 may be provided with only one pressing block 720 protruding vertically upward, and the fixing member 700 on the uppermost connecting member 300 may be provided with only one pressing block 720 protruding vertically downward, so that only one photovoltaic module 400 needs to be limited and pressed. Of course, in order to reduce the specifications of the fixing member 700 and facilitate batch processing and use, the fixing member 700 can all use the same specification, and all the fixing members 700 can be provided with two pressing blocks 720. Only one pressing block 720 of the fixing members 700 at the uppermost and lowermost positions does not actually function, but this makes the specifications of the fixing member 700 unified, facilitating unified production and use. During use, there is no need for manual discrimination, and they can also be packaged and used together.

[0060] Referring to Figure 4 , in a further embodiment of the present invention, the support plate 210 is provided with first connection holes 211, and the bottom ends of the left and right sides of the connecting member 300 are provided with second connection holes 301. The first connection holes 211 are aligned with the second connection holes 301 and are installed with fasteners.
