[0002] Photovoltaic-transport integration is a technology that combines solar power generation with transportation infrastructure, aiming to achieve a balance between energy self-sufficiency and aesthetic appeal in transportation. In recent years, the application of photovoltaics in highways and municipal infrastructure in China has been developing from pilot projects to large-scale deployments. The main models include self-consumption in service areas, combined utilization of slopes / sound barriers, and integrated photovoltaic-energy storage-charging systems. In the future, with technological maturity and policy support, photovoltaics will become a crucial support for low-carbon and intelligent transportation.

[0003] The application of photovoltaic (PV) transportation integration in bridges is gaining increasing attention, especially the installation of PV systems on urban and highway bridges. This not only utilizes the unused space on bridges to generate electricity but also reduces reliance on traditional energy sources. However, current PV panel installations on bridge railings often suffer from unstable connections, particularly on bridges with significant curves. When the railing is struck by a vehicle or in strong winds, the PV panels are prone to loosening. Increasing the number of connecting components could significantly increase the load on the bridge, affecting its load-bearing capacity.

[0004] Therefore, it is necessary to propose a new type of photovoltaic guardrail structure and system to solve or at least alleviate the above-mentioned defects. Utility Model Content

[0032] Please see the appendix Figure 1-5 This utility model provides a novel photovoltaic guardrail 20 structure in one embodiment, comprising a load-bearing component 10, a guardrail 20, and a plurality of photovoltaic panels 30 spaced apart along the longitudinal direction of the bridge. First, it should be noted that in this application, the longitudinal direction of the bridge refers to the direction along the extension of the bridge, the transverse direction of the bridge refers to the direction along the width of the bridge, and the outer side refers to the side away from the bridge. The specific design is as follows:

[0033] The load-bearing component 10 includes a prestressed steel strand 110, a connecting component 120, a photovoltaic panel connector 130, and two side anchor structures 140 arranged opposite each other at both ends of the guardrail 20 along the longitudinal direction of the bridge. The side anchor structures 140 are used to fix the guardrail 20 to the slopes of the roads at both ends of the bridge. The two ends of the prestressed steel strand 110 are respectively connected to the two side anchor structures 140 to extend along the longitudinal direction between the two side anchor structures 140. The two ends of the prestressed steel strand 110 are respectively installed on the outside of the guardrail 20 through the connecting component 120. The photovoltaic panel 30 is connected to the prestressed steel strand 110 through the photovoltaic panel connector 130.

[0034] Specifically, the novel photovoltaic guardrail 20 structure in this application includes a load-bearing component 10, a guardrail 20, and multiple photovoltaic panels 30 spaced apart along the longitudinal direction of the bridge. The guardrail 20 is located at the side end of the bridge. The load-bearing component 10 is used to install the multiple photovoltaic panels 30 to support their main load-bearing function. Specifically, it includes prestressed steel strands 110, connecting components 120, photovoltaic panel connectors 130, and two side anchor structures 140 arranged opposite to each other at both ends of the guardrail 20 along the longitudinal direction of the bridge. The prestressed steel strands 110 and the side anchor structures 140 serve as the main load-bearing components.

[0035] The side anchor structure 140 is used to fix it to the bridge. Two side anchor structures 140 are respectively distributed at both ends of the guardrail 20 to facilitate the tensioning of the prestressed steel strands 110. After tensioning, the prestressed steel strands 110 are in a horizontal state, which can improve the load-bearing capacity and facilitate the connection of the photovoltaic panels 30. In a preferred embodiment of this application, there are two prestressed steel strands 110. The two prestressed steel strands 110 are arranged vertically at intervals to improve the stability of the photovoltaic panels 30 after connection and ensure balance. After the photovoltaic panels 30 are connected to the prestressed steel strands 110 with the photovoltaic panel connectors 130, the two prestressed steel strands 110 are respectively distributed at the upper and lower ends of the photovoltaic panels 30, and the installation is stable. The tensioned prestressed steel strands 110 can be connected to the guardrail 20 through the connecting components 120, so that the photovoltaic panels 30 are installed on the guardrail 20 to form a photovoltaic guardrail 20 structure.

[0036] In a preferred embodiment of the present invention, each of the side anchor structures 140 includes a PHC pile 141, a first steel strand 142, and a second steel strand 143. The PHC pile 141 is used to fix the bridge to the slope of the road at both ends. The two ends of the first steel strand 142 are respectively connected to the PHC pile 141 and the prestressed steel strand 110 located above it. The two ends of the second steel strand 143 are respectively connected to the PHC pile 141 and the prestressed steel strand 110 located below it.

[0037] It should be noted that PHC pile 141 is a prestressed high-strength concrete pile, a type of high-strength precast concrete pile manufactured using prestressing technology. It possesses high strength, high durability, and good crack resistance. It is connected to prestressed steel strands 110 via steel strands to share the load. Considering that there are two prestressed steel strands 110 in this application, each of the aforementioned side anchor structures 140 also needs to be equipped with two steel strands (i.e., the first steel strand 142 and the second steel strand 143). Both the first steel strand 142 and the second steel strand 143... The main function is to connect and tighten. The first steel strand 142 is used to connect the PHC pile 141 and the prestressed steel strand 110 located above it. The second steel strand 143 is used to connect the PHC pile 141 and the prestressed steel strand 110 located below it. Thus, when the load is applied to the prestressed steel strand 110, the prestressed steel strand 110 then transfers the load to the PHC pile 141 through the first steel strand 142 and the second steel strand 143, thereby sharing part of the load and reducing the impact of this structure on the bridge's load-bearing capacity. It is suitable for bridges with large spans.

[0038] In a preferred embodiment of the present invention, the connecting assembly 120 includes a steel profile 121 and a fastener 122. The steel profile 121 extends vertically and is fixed to the outer end of the guardrail 20. The fastener 122 is bolted to the steel profile 121. The end of the prestressed steel strand 110 passes through the fastener 122 to be installed on the outer side of the guardrail 20.

[0039] It is worth noting that the steel section 121 facilitates the connection of steel strands. Due to its optimized cross-sectional shape, the steel section 121 has good load-bearing capacity. It can be welded to the guardrail 20. The steel section 121 is easy to process, and bolt holes can be machined for bolt connection by the fastener 122. In this way, the prestressed steel strand 110 is fastened to the steel section 121 by the fastener 122, which facilitates the positioning and installation of the prestressed steel strand 110. Preferably, the steel section 121 is an H-beam. H-beams are low-cost and easy to process while ensuring load-bearing capacity.

[0040] In a preferred embodiment of the present invention, the photovoltaic panel connector 130 includes an arc-shaped groove 131 and two connecting plates 132. The arc-shaped groove 131 is used for the prestressed steel strand 110 to pass through. The two connecting plates 132 are respectively connected to the two sides of the opening end of the arc-shaped groove 131, and both connecting plates 132 are connected to the photovoltaic panel 30 by bolts.

[0041] It is worth noting that the photovoltaic panel connector 130 adopts a combination structure of arc groove 131 and connecting plate 132. The arc groove 131 is used for the prestressed steel strand 110 to pass through, and the connecting plate 132 is used for bolt connection with the photovoltaic panel 30. In this way, the photovoltaic panel 30 is installed on the prestressed steel strand 110 by snap-fit ​​installation, and the bolt connection method facilitates disassembly and assembly, and facilitates later maintenance. In a preferred embodiment of this application, each photovoltaic panel 30 is provided with four photovoltaic panel connectors 130. The four photovoltaic panel connectors 130 are distributed in a matrix at the four corners of the photovoltaic panel 30. In this way, photovoltaic panel connectors 130 can be provided at both the top and bottom ends to improve the connection stability of the photovoltaic panel 30 and prevent loosening.

[0042] Furthermore, the photovoltaic panel 30 is inclined towards the outside of the bridge from the top to the bottom.

[0043] It should be understood that this can better improve the amount of light received, and the tilted setting is more convenient for rainwater to wash away, reducing the problem of light reception being blocked by dust accumulation; preferably, the angle between the tilted surface and the vertical surface of the photovoltaic panel 30 is 5° to 7°, and those skilled in the art can select according to actual needs.

[0044] This application also provides a novel photovoltaic guardrail 20 system, including multiple novel photovoltaic guardrail 20 structures as described above, with the multiple novel photovoltaic guardrail 20 structures arranged sequentially along the longitudinal direction of the bridge.

[0045] Understandably, by arranging the photovoltaic panels 30 sequentially along the extension direction of the bridge on the sides, the entire system not only provides the protection of the guardrail 20, but also integrates photovoltaic and transportation systems. The photovoltaic panels 30 are stably connected, and the combination of prestressed steel strands 110 and side anchor structures 140 provides good load-bearing capacity and has little impact on the bridge's load-bearing capacity.

[0046] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
