[0024] Explanation of related terms:

[0025] Photovoltaic support system:

[0026] Photovoltaic (PV) mounting systems are structures used to support and secure photovoltaic (PV) modules, ensuring their stability and safety under various environmental conditions. These systems are typically made of aluminum alloy or hot-dip galvanized steel, offering properties such as corrosion resistance, wind pressure resistance, and snow load resistance. Based on the installation method, PV mounting systems can be categorized into ground-mounted systems, rooftop systems, and tracking systems. A well-designed mounting system not only improves the power generation efficiency of the PV system but also extends the equipment's lifespan. PV mounting systems play a vital role in the renewable energy sector.

[0027] Floating photovoltaic system:

[0028] Floating photovoltaic (PV) systems are a renewable energy generation technology that installs photovoltaic modules on the water surface. The system uses pontoons or floating frames to support the PV panels, effectively utilizing water space and reducing land occupation. The floating design reduces the temperature of the PV modules, improving power generation efficiency while minimizing water evaporation and algae growth. Suitable for reservoirs, lakes, offshore areas, and industrial pools, this system offers advantages such as environmental friendliness, energy conservation, and emission reduction, and is gradually becoming an important development direction for global photovoltaic power generation.

[0029] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] Reference Figures 1-5This utility model provides a double-row integrated photovoltaic support structure, comprising:

[0031] Support components are used for mounting on float 1;

[0032] The support structure is used to install two photovoltaic modules 2. The support structure includes a front support leg 3, a middle support leg 4 and a rear support leg 5 mounted on a support member. The front and rear ends of one photovoltaic module 2 are respectively mounted on the front support leg 3 and the middle support leg 4, and the front and rear ends of the other photovoltaic module 2 are respectively mounted on the middle support leg 4 and the rear support leg 5. The two photovoltaic modules 2 are tilted in the same direction and there is a gap between the two photovoltaic modules 2.

[0033] In some alternative embodiments, the middle support leg 4 includes a base frame 6, on which two vertical plates 7 are fixedly connected. There is a gap between the two vertical plates 7. The top sides of the two vertical plates 7 that are opposite to each other are respectively fixedly connected to a first support plate 8. The two first support plates 8 are respectively used to support the bottom of the frame of the two photovoltaic modules 2 and are connected to the frame of the photovoltaic modules 2 by bolts.

[0034] In some optional embodiments, a second support plate 9 is fixedly connected to the top of the front support leg 3, and a third support plate 10 is fixedly connected to the top of the rear support leg 5. The bottom of the front and rear ends of one photovoltaic module 2 frame are respectively supported on the top of the second support plate 9 and the top of the first support plate 8 near the front support leg 3, and the bottom of the front and rear ends of the other photovoltaic module 2 frame are respectively supported on the top of the first support plate 8 near the rear support leg 5 and the top of the third support plate 10. The third support plate 10, the second support plate 9, the first support plate 8 and the photovoltaic module 2 frame are connected by bolts.

[0035] In some alternative embodiments, the height of the first support plate 8 near the front outrigger 3 is higher than the height of the second support plate 9, the height of the first support plate 8 near the front outrigger 3 is higher than the height of another first support plate 8, and the height of the first support plate 8 near the rear outrigger 5 is lower than the height of the third support plate 10.

[0036] In some alternative embodiments, the first support plate 8, the second support plate 9 and the third support plate 10 are all inclined relative to the horizontal plane and the inclination and tilt angle are consistent.

[0037] In some alternative embodiments, a U-shaped stop 11 is sandwiched between the two vertical plates 7, and hexagonal bolts 12 pass through the two vertical plates 7 and the U-shaped stop 11 and are locked by nuts 13.

[0038] Furthermore, flat washers 15 are sandwiched between the nut of the hexagonal bolt 12 and the vertical plate 7, and between the nut 13 and the vertical plate 7.

[0039] In some alternative embodiments, the support includes a crossbeam 14, with both ends of the crossbeam 14 fixed to the two floats 1 respectively, and the front outrigger 3, the base frame 6 and the rear outrigger 5 are all fixed to the crossbeam 14 by multiple bolts.

[0040] During installation, this invention follows a bottom-up principle. First, two floating bodies 1 are installed, followed by a crossbeam 14 on each floating body 1. A front support leg 3, a middle support leg 4, and a rear support leg 5 are arranged on the crossbeam 14. The two photovoltaic modules 2 share a single support leg structure. The front support leg 3, middle support leg 4, and rear support leg 5 form a unified structure, ensuring that the external load on the two photovoltaic modules 2 is evenly distributed across the support legs, resulting in better stress distribution and further distributing the load evenly across the crossbeam 14 and the floating bodies 1.

[0041] The middle support leg 4 has a height difference between its front and rear sections to prevent the photovoltaic modules from being shaded. On the higher side of the middle support leg 4, the first support plate 8 is connected to the front support leg 3 to mount a photovoltaic module 2. On the lower side of the middle support leg 4, the first support plate 8 forms an upward tilt angle and is connected to the rear support leg 5 to mount a photovoltaic module 2. Based on a conventional fixed-angle floating photovoltaic support system, one front support leg and one rear support leg are combined into one middle support leg. This saves materials and increases the overall stability and stability of the system.

[0042] To enhance the overall integrity and system integration of the front and rear photovoltaic modules, a U-shaped stop 11 is installed in the middle of the central support leg 4, connected with hexagonal bolts 12. Facing complex external environments, such as strong winds and waves at sea, the front and rear photovoltaic modules form a unified whole with the support leg. This results in more even stress distribution, stronger overall integrity, and greater resistance to overturning.

[0043] The overall structural diagram of the photovoltaic system installation in this application is as follows: Figure 1 As shown, float 1 is the core component of the floating photovoltaic system, typically made of high-density polyethylene (HDPE) or other polymers, characterized by low density, corrosion resistance, UV resistance, and environmental friendliness. Float 1 adopts a pontoon structure, which can be flexibly adjusted according to water depth and level changes. The spacing between floats 1 can be integrated with aquaculture. Increased underwater shadows in the photovoltaic system allow for the cultivation of shade-loving plants and animals, as well as the management of sun-loving plants and animals. Floats 1 are connected by connecting rods 16, thus linking the photovoltaic module power generation system and the photovoltaic operation and maintenance passageway, making the system more stable. The connecting rods 16 can be made of metal or non-metallic polymer components.

[0044] Advantages of the photovoltaic support structure in this application:

[0045] 1. The two photovoltaic modules 2 are supported by a support structure consisting of a front support leg 3, a middle support leg 4, and a rear support leg 5, which makes the overall structure stronger.

[0046] 2. Improved water area utilization: By shortening the horizontal spacing between the front and rear photovoltaic modules, the same installed capacity can be achieved by reducing the front and rear spacing of the floats, thereby reducing the amount of crossbeams used.

[0047] 3. Set a height difference between the front and rear of photovoltaic module 2 to ensure that photovoltaic module 2 is not shaded.
