[0021] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0022] like Figures 1 to 3As shown, the floating offshore photovoltaic power generation platform 100 of the embodiment of the present invention includes a top frame 1, a bottom frame 2, a plurality of first columns 3, a plurality of buoys 4, a mounting frame 5 and a photovoltaic panel 6. The top frame 1 and the bottom frame 2 are arranged at intervals in the vertical direction, each of the top frame 1 and the bottom frame 2 is a polygonal frame, and the top frame 1 and the bottom frame 2 have the same number of sides. In the projection plane orthogonal to the vertical direction, the vertices of the top frame 1 correspond to and coincide with the vertices of the bottom frame 2. A first column 3 is provided between the vertices of the top frame 1 and the vertices of the bottom frame 2, and the buoy 4 is provided on the bottom frame 2 to provide buoyancy for the bottom frame 2.

[0023] The mounting frame 5 is arranged in the space enclosed by the top frame 1, and includes a plurality of horizontal bars 502 and a plurality of vertical bars 501. The plurality of horizontal bars 502 are arranged at intervals in the first direction, and the horizontal bars 502 extend along the second direction to connect with the top frame 1. The plurality of vertical bars 501 are arranged at intervals in the second direction, and the vertical bars 501 extend along the first direction to connect with the top frame 1. A plurality of mounting frames are defined between the plurality of horizontal bars 502 and the plurality of vertical bars 501, wherein the first direction is perpendicular to the second direction, and the photovoltaic panel 6 is fixed on the mounting frames.

[0024] In the floating offshore photovoltaic power generation platform 100 of the embodiment of the present invention, the mounting frame 5 is provided with crisscrossing cross bars 502 and longitudinal bars 501 to define the mounting frame, and the photovoltaic panel 6 can be directly fixed on the frame. The formation of the mounting frame enables the photovoltaic panel 6 to be more firmly fixed on the platform, thereby enhancing the wind and wave resistance and structural stability of the entire photovoltaic power generation platform. Since the photovoltaic panel 6 is directly mounted on the mounting frame, the use of supporting structures such as columns is reduced, which can save more space, make the layout of the entire platform more compact, and improve space utilization. The simplified structure reduces protrusions such as columns, thereby reducing wind resistance, making the photovoltaic power generation platform less affected by wind at sea, and improving the weather resistance of the platform. The amount of materials such as columns is reduced, the material cost is reduced, and the difficulty of installation and maintenance is also reduced, further reducing the cost of the entire project. The design of the mounting frame makes the replacement and maintenance of the photovoltaic panel 6 more convenient and quick, and only the frame part needs to be operated, without major adjustments to the entire structure.

[0025] In some embodiments, the floating offshore photovoltaic power generation platform 100 of the embodiment of the present invention also includes a junction box 7 and an inverter 8. The junction box 7 and the inverter 8 are both arranged on the mounting frame 5 and located at the center of the top frame 1. The junction box 7 and the inverter 8 are electrically connected to the photovoltaic panel 6.

[0026] Arranging the combiner box 7 and the inverter 8 at the center of the top frame 1 is conducive to centralized management and maintenance, simplifies the circuit layout, and improves the reliability of system operation. Since the combiner box 7 and the inverter 8 are located near the photovoltaic panel 6, the length of the cable can be effectively reduced, thereby reducing the energy loss of the cable.

[0027] In some embodiments, a plurality of first aisles 9 and a plurality of second aisles 10 are provided on the mounting frame 5, the plurality of first aisles 9 are arranged at intervals along the first direction, the first aisles 9 extend along the second direction to the top frame 1, and the plurality of second aisles 10 are arranged at intervals along the second direction, the second aisles 10 extend along the first direction to the top frame 1.

[0028] The provision of the first walkway 9 and the second walkway 10 provides a safe and stable passage, allowing the staff to move safely on the mounting frame 5, facilitating installation, maintenance and overhaul work. The existence of the walkway enables the staff to quickly reach any position of the photovoltaic panel 6, improving work efficiency and shortening maintenance time. The walkway can provide a path for cables and other electrical wiring, helping to keep the wiring neat and orderly and reduce the possibility of failure. The existence of the walkway makes it easier to monitor the platform, and the staff can visually inspect the photovoltaic panel 6 on the walkway to detect potential problems in a timely manner. The design of the walkway takes into account the maximum utilization of space, does not occupy too much installation space, and ensures that the photovoltaic panel 6 has sufficient installation area. The design of the walkway helps to isolate the space between the working area and the photovoltaic panel 6, reducing the interference of the staff with the photovoltaic panel 6 during operation.

[0029] In some embodiments, the top frame 1 forms an annular walkway, which is connected to the first walkway 9 and the second walkway 10.

[0030] The setting of the circular walkway provides a passage path around the top of the entire platform, so that the staff can fully cover the entire installation area and improve the convenience of passage. The circular walkway is connected to the first walkway 9 and the second walkway 10 to form a complete passage network. The staff can quickly move from one area to another, greatly improving the maintenance efficiency. The staff can patrol along the circular walkway, find and deal with problems in a timely manner, optimize the work process, and reduce unnecessary duplication of work. In an emergency, the circular walkway facilitates rapid emergency response, and the staff can quickly reach the problem location and deal with emergencies in a timely manner. The design of the circular walkway will not affect the installation area of ​​the photovoltaic panel 6, while ensuring the full utilization of the walkway space and will not cause space waste. The design of the circular walkway helps to enhance the overall stability of the top frame 1 and improve the wind and wave resistance of the entire platform.

[0031] Optionally, the width of the first aisle 9 and / or the second aisle 10 is 20 cm-30 cm.

[0032] The width of 20cm-30cm provides workers with enough space to pass and work without appearing crowded or wasting space. Walkways of this width can ensure that workers remain stable when walking and reduce the risk of falling, especially in offshore environments, where improved safety is particularly important. The appropriate width of the walkway makes it more convenient to install and maintain photovoltaic panels 6 and related equipment, and workers can operate comfortably. Compared with walkways that are too wide, a width of 20cm-30cm can save materials and reduce costs, and at the same time will not cause too much impact on the installation area of ​​photovoltaic panels 6. The narrower walkway design helps to reduce the wind resistance of the overall structure and improve the wind resistance of the platform, especially in offshore environments with strong winds.

[0033] In some embodiments, a fence 11 is provided at the edge of the top frame 1 , and the fence 11 is arranged around the top frame 1 .

[0034] The existence of the fence 11 provides a protective barrier for the workers to prevent them from falling or accidentally sliding under the platform during work. Especially in the offshore environment, the safety of the fence 11 is very important. The fence 11 can effectively prevent foreign objects (such as waves, floating objects, etc.) from directly hitting the photovoltaic panel 6, protecting the photovoltaic panel 6 from damage. The fence 11 provides a safer working environment for the workers, allowing them to focus more on maintenance and operation work and improve work efficiency.

[0035] In some embodiments, a plurality of flashing lights 12 are disposed on the fence 11 , and the plurality of flashing lights 12 are arranged at intervals along the circumference of the fence 11 .

[0036] The design of the flashing light 12 improves the visibility of the photovoltaic power generation platform at night or in low visibility conditions, which is very important for navigation safety and avoiding conflicts with other marine activities. The flashing light 12 can be used as a warning signal to remind passing ships and aircraft of the presence of the platform, prevent accidental collisions, and ensure marine safety. In emergency situations, such as bad weather or marine rescue operations, the flashing light 12 can help rescue teams quickly locate the location of the photovoltaic power generation platform. For situations where maintenance or emergency repairs are required at night, the flashing light 12 can provide the necessary light source to help workers work safely in dark environments.

[0037] In some embodiments, a climbing ladder 13 is provided between the top frame 1 and the bottom frame 2 , and both ends of the climbing ladder 13 are respectively connected to the top frame 1 and the bottom frame 2 , and the climbing ladder 13 extends in the vertical direction.

[0038] The climbing ladder 13 provides workers with a convenient passage from the bottom frame 2 to the top frame 1, allowing them to move up and down safely and quickly. With the climbing ladder 13, workers can save time going up and down the platform, thereby improving overall work efficiency. The design of the climbing ladder 13 usually includes handrails and non-slip steps, which provides a safer climbing environment for workers and reduces risks during the climbing process.

[0039] In some embodiments, at least one side of the climbing ladder 13 is provided with a support rod 14, the support rod 14 extends in the vertical direction, and an L-shaped rod 15 is provided on the support rod 14. The L-shaped rod 15 includes a first rod body 1501 and a second rod body 1502, the first rod body 1501 is arranged perpendicular to the support rod 14, and the second rod body 1502 is arranged parallel to the support rod 14 and spaced from the support rod 14, and the second rod body 1502 extends upward in the vertical direction. The L-shaped rod 15 is used for mooring ships.

[0040] The provision of the support rod 14 enhances the stability of the climbing ladder 13, especially in a marine environment, and can resist the influence of wind and waves, thereby ensuring the stability of the climbing ladder 13. The design of the L-shaped rod 15 as a mooring point for ships improves the practicality of the platform. The second rod body 1502 of the L-shaped rod 15 is provided parallel to the support rod 14, which can provide an additional fixing point for moored ships and increase the safety of mooring. The presence of the L-shaped rod 15 provides a clear mooring position for ships, facilitating the berthing and unberthing operations of ships. The provision of the L-shaped rod 15 can play a buffering role when the ship is moored, reducing the impact force of the ship on the platform due to the influence of wind and waves.

[0041] In some embodiments, the float 4 is a hollow structure, and an injection hole is opened on the float 4, and the injection hole is used to inject the foaming agent into the float 4.

[0042] The hollow structure of the buoy 4 itself can provide a certain buoyancy, and by injecting a foaming agent into the buoy 4, the buoyancy can be further increased to ensure that the photovoltaic power generation platform can float stably on the water surface. By injecting a foaming agent into the buoy 4 through the injection hole, the buoyancy of the buoy 4 can be adjusted according to actual needs to adapt to different water environments and load requirements. The uniform foam structure formed by the foaming agent inside the buoy 4 helps to improve the stability of the buoy 4, making it less likely to deform or damage when it is hit by wind and waves. If the buoy 4 is damaged, it can be repaired through the injection hole, and repair materials or foaming agents can be injected to restore its buoyancy. The design of the hollow structure allows the buoy 4 to be customized according to different design requirements, such as adjusting the size, shape and buoyancy distribution. The hollow buoy 4 filled with a foaming agent can provide an additional protective layer to protect the inside of the buoy 4 from erosion by environmental factors such as seawater. The hollow structure filled with a foaming agent can absorb and reduce noise and vibration in a marine environment, thereby improving the comfort and stability of the platform. The buoy 4 with a hollow structure is usually lighter and easier to handle during installation and transportation.
