[0023] 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.

[0024] like Figures 1 to 5 As 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 buoy 4, a plurality of first photovoltaic panels 5, a plurality of second photovoltaic panels 6 and a support column 7. 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, and a column 3 is provided between the top frame 1 and the bottom frame 2. The buoy 4 is provided on the bottom frame 2 to provide buoyancy for the bottom frame 2, and a plurality of first photovoltaic panels 5 are provided at the edge of the top frame 1 and are arranged around the top frame 1, and the first photovoltaic panels 5 extend in the vertical direction. The second photovoltaic panel 6 is provided in the space enclosed by the plurality of first photovoltaic panels 5 through the support column 7, and the second photovoltaic panel 6 is located above the first photovoltaic panel 5.

[0025] The floating offshore photovoltaic power generation platform 100 of the embodiment of the present invention is provided with columns 3 between the top frame 1 and the bottom frame 2, which ensures the stability of the platform and facilitates installation and maintenance. The platform uses buoys 4 as support, can adapt to different water depths and ocean current conditions, and has strong environmental adaptability. The offshore photovoltaic power generation platform reduces the occupation of land resources, and at the same time, because it is a clean energy, it can reduce greenhouse gas emissions and is beneficial to environmental protection.

[0026] The floating offshore photovoltaic power generation platform 100 of the embodiment of the present invention is provided with a first photovoltaic panel 5 around the edge of the top frame 1, and a second photovoltaic panel 6 is provided above the space enclosed by the first photovoltaic panel 5, so that more photovoltaic panels can be arranged in the same vertical space, thereby increasing the total power generation area, making the arrangement of the photovoltaic panels more compact, thereby increasing the overall power generation, and thus effectively improving the power generation efficiency per unit area. Therefore, the floating offshore photovoltaic power generation platform 100 of the embodiment of the present invention has the advantage of high area utilization, thereby making the power generation efficiency per unit area high, and improving the overall power generation efficiency.

[0027] In some embodiments, the second photovoltaic panel 6 is tilted relative to the top frame 1 .

[0028] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the floating offshore photovoltaic power generation platform 100 of the embodiment of the present invention can form a better angle between its surface and sunlight by tilting the second photovoltaic panel 6, especially when the sun is low in the morning and evening, the tilted photovoltaic panel can absorb sunlight more effectively and improve the power generation efficiency. The tilted setting can better adapt to the seasonal changes in the angle of sunlight, so that the photovoltaic panel can maintain a high energy conversion efficiency in different seasons. The tilted photovoltaic panel can arrange more photovoltaic panels in a limited space, further optimize the space utilization, and improve the power generation capacity of the entire platform. The tilted setting helps to improve the heat dissipation conditions of the photovoltaic panel, because the air flow and heat dissipation efficiency will be improved due to the tilt angle, which helps to maintain the working temperature of the photovoltaic panel and improve its performance. The tilted photovoltaic panel surface is not easy to accumulate dust and dirt, which helps to keep the photovoltaic panel clean, reduce the cleaning frequency and maintenance cost. The appropriate tilt angle can also enhance the stability of the entire platform, especially in the face of severe sea conditions such as wind and waves, the tilted photovoltaic panel helps to reduce wind load and enhance the wind resistance of the platform.

[0029] In some embodiments, Figure 4 and Figure 5As shown, the second light panel includes a first inclined plate 601 and a second inclined plate 602, each of which is arranged at an angle with the top frame 1, and the first inclined plate 601 and the second inclined plate 602 gradually move away from each other from top to bottom.

[0030] The floating offshore photovoltaic power generation platform 100 of the embodiment of the present invention can maximize the absorption of sunlight by the photovoltaic panel at different time periods and different solar altitude angles by setting the first inclined plate 601 and the second inclined plate 602 at different angles, thereby improving the overall power generation efficiency. Since the first inclined plate 601 and the second inclined plate 602 have different angles, they can adapt to low-angle and high-angle sunlight respectively, so that the photovoltaic panel can work efficiently at different times of the day. As the height increases, the spacing between the first inclined plate 601 and the second inclined plate 602 decreases. This arrangement helps to reduce wind resistance, improve the wind resistance of the platform, and reduce structural fatigue caused by wind. Since there is a larger space between the two inclined plates, this helps to improve the heat dissipation performance of the photovoltaic panel and prevent performance degradation caused by high temperature. This structural design makes it easier to clean and maintain the photovoltaic panel because the space between the two inclined plates allows staff to more easily access the photovoltaic panel.

[0031] In some embodiments, the first inclined plate 601 and / or the second inclined plate 602 are inclined at an angle of 10°-15° relative to the top frame 1 .

[0032] An angle of 10°-15° is a relatively ideal angle for sunlight absorption in many areas. This angle range can usually ensure that photovoltaic panels can efficiently absorb sunlight for most of the day. This angle can ensure that the photovoltaic panels absorb sufficient light without reducing the structural stability due to excessive angles. A moderate tilt angle helps to reduce the impact of wind on photovoltaic panels and reduce the structural load caused by wind, thereby improving the wind resistance of the platform. Compared with a larger tilt angle, a tilt angle of 10°-15° may require less materials and simpler support structures during construction and installation, which helps to reduce overall project costs. A moderate tilt angle helps to reduce mutual shading between photovoltaic panels.

[0033] In summary, the floating offshore photovoltaic power generation platform 100 of the embodiment of the present invention can achieve efficient light energy conversion while maintaining structural stability by setting the first inclined plate 601 and / or the second inclined plate 602 to an inclination angle of 10°-15°, thereby providing a reliable and efficient technical solution for the utilization of offshore renewable energy.

[0034] In some embodiments, the plurality of second photovoltaic panels 6 form a plurality of photovoltaic groups, the plurality of photovoltaic groups are spaced apart along a first direction, and the photovoltaic groups include a plurality of second photovoltaic panels 6 spaced apart along a second direction, wherein the first direction is perpendicular to the second direction.

[0035] The vertical arrangement of the first direction and the second direction helps to maximize the area of ​​the photovoltaic panels, so that each photovoltaic panel can fully utilize its surface area to absorb sunlight. The second photovoltaic panels 6 arranged at intervals along the second direction inside the photovoltaic group help to reduce mutual shading between photovoltaic panels in the same group and improve the power generation efficiency of each panel. By adjusting the number of photovoltaic groups and the number of photovoltaic panels in each photovoltaic group, it can meet the power generation needs of different scales.

[0036] The floating offshore photovoltaic power generation platform 100 of the embodiment of the present invention can arrange the photovoltaic groups at intervals so that each photovoltaic group can receive sufficient sunlight, reduce mutual shading, and improve the overall light utilization efficiency. The intervals between the photovoltaic groups are conducive to air flow, which helps the heat dissipation of the photovoltaic panels and reduces the performance degradation caused by high temperature. The interval arrangement can reduce the wind load of the overall structure and enhance the stability of the platform in severe sea conditions. The interval arrangement of multiple photovoltaic groups makes the design of the entire platform more modular, and the number of photovoltaic groups can be flexibly increased or decreased according to actual needs.

[0037] The vertical arrangement of the first direction and the second direction helps to maximize the area of ​​the photovoltaic panels, so that each photovoltaic panel can fully utilize its surface area to absorb sunlight. The second photovoltaic panels 6 arranged at intervals along the second direction inside the photovoltaic group help to reduce mutual shading between photovoltaic panels in the same group and improve the power generation efficiency of each panel. By adjusting the number of photovoltaic groups and the number of photovoltaic panels in each photovoltaic group, it can meet the power generation needs of different scales.

[0038] In some embodiments, the distance between two adjacent second photovoltaic panels 6 in the photovoltaic group is L1, wherein 10 cm≤L≤15 cm.

[0039] Appropriate spacing can reduce mutual shading between adjacent photovoltaic panels, ensuring that each photovoltaic panel can fully absorb sunlight, thereby improving power generation efficiency. A spacing of 10cm to 15cm can provide sufficient air flow space, which helps dissipate heat from photovoltaic panels and keep the operating temperature of photovoltaic panels within an appropriate range. This spacing range can provide sufficient strength for the supporting structure to ensure the stability of the photovoltaic group under severe sea conditions. Reasonable spacing makes it easier for staff to approach and operate photovoltaic panels for cleaning and maintenance. The existence of spacing can reduce the area of ​​wind acting on photovoltaic panels, thereby reducing wind loads and reducing fatigue damage to the structure caused by wind.

[0040] In some embodiments, the distance between two adjacent photovoltaic groups is L2, wherein 10 cm≤L2≤15 cm.

[0041] Appropriate spacing can reduce mutual shading between adjacent photovoltaic panels, ensuring that each photovoltaic panel can fully absorb sunlight, thereby improving power generation efficiency. A spacing of 10cm to 15cm can provide sufficient air flow space, which helps dissipate heat from photovoltaic panels and keep the operating temperature of photovoltaic panels within an appropriate range. This spacing range can provide sufficient strength for the supporting structure to ensure the stability of the photovoltaic group under severe sea conditions. Reasonable spacing makes it easier for staff to approach and operate photovoltaic panels for cleaning and maintenance. The existence of spacing can reduce the area of ​​wind acting on photovoltaic panels, thereby reducing wind loads and reducing fatigue damage to the structure caused by wind.

[0042] In some embodiments, a fence 8 is provided at the edge of the top frame 1 , and the fence 8 is arranged around the top frame. The first photovoltaic panel 5 is arranged on the fence 8 and is located on the outside of the fence 8 .

[0043] like Figure 2 As shown, the fence 8 surrounds the top frame, providing an additional safety layer for the photovoltaic power generation platform, preventing people and objects from accidentally falling or contacting the photovoltaic panels, and reducing the risk of accidents.

[0044] The presence of fence 8 can enhance the overall structural stability of the top frame 1, especially in harsh marine environments, fence 8 can help disperse the pressure caused by wind and waves. The presence of fence 8 can provide safety protection for workers when maintaining and cleaning photovoltaic panels, allowing them to work within fence 8 and reduce operational risks. The design of fence 8 can be optimized according to different marine environments. For example, in areas susceptible to wave impact, fence 8 can be designed to be more sturdy to withstand greater impact forces. Fence 8 can also integrate other functions, such as lighting, surveillance cameras, etc., to further enhance the safety of the platform.

[0045] Optionally, a plurality of flashing lights are provided on the fence 8 , and the plurality of flashing lights are arranged at intervals along the circumference of the fence 8 .

[0046] The design of flashing lights improves the visibility of photovoltaic power generation platforms at night or in low visibility conditions, which is very important for navigation safety and avoiding conflicts with other maritime activities. Flashing lights can serve as warning signals to remind passing ships and aircraft of the presence of the platform, prevent accidental collisions, and ensure maritime safety. In emergency situations, such as bad weather or maritime rescue operations, flashing lights can help rescue teams quickly locate the location of photovoltaic power generation platforms. For situations where maintenance or emergency repairs are required at night, flashing lights can provide the necessary light source to help workers work safely in dark environments.

[0047] In some embodiments, a climbing ladder 9 is provided between the top frame 1 and the bottom frame 2 , and both ends of the climbing ladder 9 are respectively connected to the top frame 1 and the bottom frame 2 , and the climbing ladder 9 extends in a vertical direction.

[0048] As shown in the figure and the figure, the climbing ladder 9 provides a convenient passage from the bottom frame to the top frame for the workers, so that they can move up and down safely and quickly. With the climbing ladder 9, the workers can save time on going up and down the platform, thereby improving the overall work efficiency. The design of the climbing ladder 9 usually includes handrails and non-slip steps, which provides a safer climbing environment for the workers and reduces the risks during the climbing process.

[0049] In some embodiments, a support rod 10 is provided on at least one side of the climbing ladder 9, and the support rod 10 extends in a vertical direction. An L-shaped rod 11 is provided on the support rod 10, and the L-shaped rod 11 includes a first rod body 1101 and a second rod body 1102. The first rod body 1101 is arranged perpendicular to the support rod 10, and the second rod body 1102 is arranged parallel to the support rod 10 and spaced apart from the support rod 10, and the second rod body 1102 extends upward in the vertical direction.

[0050] The provision of the support rod 10 enhances the stability of the climbing ladder 9, especially in a marine environment, and can resist the influence of wind and waves, thereby ensuring the stability of the climbing ladder 9. The design of the L-shaped rod 11 as a mooring point for ships improves the practicality of the platform. The second rod body 1102 of the L-shaped rod 11 is provided parallel to the support rod 10, which can provide an additional fixing point for moored ships and increase the safety of mooring. The presence of the L-shaped rod 11 provides a clear mooring position for the ship, facilitating the berthing and unberthing operations of the ship. The provision of the L-shaped rod 11 can play a buffering role when the ship is moored, reducing the impact force exerted on the platform by the ship due to the influence of wind and waves.
