[0022] 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.

[0023] like Figures 1 to 5 As shown, the floating offshore photovoltaic power generation platform 100 of the embodiment of the present invention comprises a top frame 1, a bottom frame 2, a buoy 4, a plurality of first photovoltaic panels 5 and a plurality of second photovoltaic panels 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, and a column 3 is provided between the top frame 1 and the bottom frame 2.

[0024] The buoy 4 is arranged on the bottom frame 2 to provide buoyancy for the bottom frame 2. A plurality of first photovoltaic panels 5 are laid flat on the top frame 1, a plurality of second photovoltaic panels 6 are arranged obliquely on the top frame 1 and surround the first photovoltaic panels 5, and the second photovoltaic panels 6 are gradually inclined downward in a direction away from the first photovoltaic panels 5 in the horizontal direction.

[0025] The floating offshore photovoltaic power generation platform 100 of the embodiment of the present invention, the top frame 1 and the bottom frame 2 are both polygonal frames with the same number of sides. This symmetrical structure is conducive to improving the overall stability and resisting the impact of wind and waves. A column 3 is provided between the top frame 1 and the bottom frame 2 to enhance the overall support force of the structure, making the entire platform more solid and not easily deformed by wind. The vertices of the top frame 1 correspond to and overlap with the vertices of the bottom frame 2, which is conducive to evenly distributing the wind force on various parts of the platform and reducing the impact of concentrated wind force on a certain point or a certain area. The second photovoltaic panel 6 is arranged around the first photovoltaic panel 5 and gradually tilted downward in the horizontal direction, which helps to disperse the wind pressure, so that the wind can slide along the surface of the photovoltaic panel, reduce the direct impact of the wind on the photovoltaic panel, thereby reducing the risk of deformation or rupture of the photovoltaic panel due to excessive wind pressure, and greatly enhances the wind resistance.

[0026] Therefore, the floating offshore photovoltaic power generation platform 100 according to the embodiment of the present invention has the advantage of strong wind resistance, which helps to ensure the stable operation and power generation efficiency of the offshore photovoltaic power generation system.

[0027] In some embodiments, one end of the second photovoltaic panel 6 adjacent to the first photovoltaic panel 5 is flush with the first photovoltaic panel 5 .

[0028] like Figure 4 As shown, the floating offshore photovoltaic power generation platform 100 of the embodiment of the present invention can make more effective use of limited space and improve the installation density of photovoltaic panels by making the second photovoltaic panel 6 flush with the first photovoltaic panel 5, thereby increasing the power generation capacity. The arrangement of one end of the second photovoltaic panel 6 flush with the first photovoltaic panel 5 can reduce wind resistance, because this structure helps to reduce the contact area of ​​the wind and reduce the force of the wind on the photovoltaic panel. The flush setting also simplifies the installation process because the consistency between the components reduces the adjustment and adaptation work during installation. In addition, when one end of the second photovoltaic panel 6 is flush with the first photovoltaic panel 5, the mutual support between the two can increase the overall stability, especially in the case of strong winds and waves, which helps to resist external forces and reduce the swaying and vibration of the platform.

[0029] Optionally, the inclination angle of the second photovoltaic panel 6 is 10°-15°.

[0030] For example, the inclination angle of 10°-15° is 10°, 12° or 15°. The inclination angle of 10°-15° helps the photovoltaic panel to better absorb sunlight. This angle range can usually ensure that the photovoltaic panel can receive better solar radiation throughout the year, especially for the offshore environment, this angle can better capture the low-angle radiation of the sun. By adjusting the inclination angle of the second photovoltaic panel 6, the surface of the photovoltaic panel can be more closely matched with the angle of sunlight, thereby improving the power generation efficiency of the photovoltaic panel. Compared with a larger inclination angle, an inclination angle of 10°-15° can reduce the frontal impact of wind on the photovoltaic panel, thereby reducing wind loads and reducing the potential risk of damage caused by excessive wind. An appropriate inclination angle helps to improve the stability of the entire photovoltaic platform. Too large an inclination angle may cause the center of gravity of the structure to be unstable, while an angle of 10°-15° can maintain a good structural balance.

[0031] In some embodiments, two adjacent first photovoltaic panels 5 are spaced apart to form a first air passage 7 .

[0032] Since the first wind passage 7 is formed by the interval arrangement between adjacent first photovoltaic panels 5, when encountering extreme weather conditions at sea such as strong waves and typhoons, strong winds will flow through the first wind passage 7 between adjacent first photovoltaic panels 5, which can effectively reduce the direct impact of wind on the first photovoltaic panels 5 and reduce wind loads, thereby reducing the deformation and rupture risks of the first photovoltaic panels 5 and further improving the wind resistance.

[0033] In some embodiments, two adjacent second photovoltaic panels 6 are spaced apart to form a second air passage 8 .

[0034] Since the intervals between adjacent second photovoltaic panels 6 form a second wind channel 8, when encountering extreme weather conditions at sea such as strong waves and typhoons, strong winds will flow through the second wind channel 8 between adjacent second photovoltaic panels 6, which can effectively reduce the direct impact of wind on the second photovoltaic panels 6 and reduce wind loads, thereby reducing the deformation and rupture risks of the second photovoltaic panels 6 and further improving the wind resistance.

[0035] Optionally, the spacing distance between two adjacent first photovoltaic panels 5 is L, wherein 10 cm≤L≤15 cm.

[0036] like Figure 4 and Figure 5As shown, appropriate spacing can reduce the wind resistance between adjacent first photovoltaic panels 5, thereby reducing the pressure and vibration caused by wind force and improving the wind resistance of the entire platform. The spacing of 10cm to 15cm can ensure that there is enough space between the first photovoltaic panels 5 to reduce wind load while maintaining the stability of the first photovoltaic panels 5. If the spacing is too large, the space utilization rate of the platform is relatively low and the construction cost is high. If the spacing is too small, the wind resistance between adjacent first photovoltaic panels 5 will be too large, resulting in structural damage to the first photovoltaic panel 5 under the action of wind force. Such a spacing design can adapt to a variety of sea conditions and wind conditions to ensure the long-term stable operation of the photovoltaic power generation platform.

[0037] In some embodiments, the top frame 1 includes a top frame 101 and a mounting frame 102, and the mounting frame 102 is arranged in the space enclosed by the top frame 101. The mounting frame 102 includes a central frame 1021 and an edge frame 1022, the central frame 1021 is a polygonal frame, the number of sides of the central frame 1021 is the same as the number of sides of the top frame 1 and corresponds one to one, and the edge frame 1022 is arranged around the central frame 1021. The edge frame 1022 gradually tilts downward in the horizontal direction away from the central frame 1021, one end of the edge frame 1022 is connected to the central frame 1021, and the other end of the edge frame 1022 is connected to the top frame 101. The first photovoltaic panel 5 is arranged on the central frame 1021, and the second photovoltaic panel 6 is arranged on the edge frame 1022.

[0038] like Figure 5 As shown, the central frame 1021 and the edge frames 1022 provide a solid support for the entire frame. The polygonal structure of the central frame 1021 can evenly distribute the load, while the downward inclination of the edge frames 1022 helps to improve wind resistance.

[0039] By separately arranging the central frame 1021 and the edge frame 1022, the photovoltaic panels can be installed more effectively in the limited space of the top frame 1, thereby improving the space utilization. The partition design of the mounting frame 102 makes the installation process more modular, which can improve the installation efficiency and reduce the construction difficulty. The first photovoltaic panel 5 is arranged on the central frame 1021, and the second photovoltaic panel 6 is arranged on the edge frame 1022. This layout can make the spacing between the photovoltaic panels more reasonable, reduce mutual shading, and improve the power generation efficiency.

[0040] In some embodiments, a fence 9 is provided at the edge of the top frame 101 , and the fence 9 is arranged around the top frame 101 .

[0041] like Figure 1 and Figure 2As shown, the existence of the fence 9 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 9 is very important. The fence 9 can effectively prevent foreign objects (such as waves, floating objects, etc.) from directly hitting the photovoltaic panels and protect the photovoltaic panels from damage. The fence 9 provides a safer working environment for the workers, allowing them to focus more on maintenance and operation work and improve work efficiency.

[0042] Optionally, a plurality of flashing lights 10 are provided on the fence 9 , and the plurality of flashing lights 10 are arranged at intervals along the circumference of the fence 9 .

[0043] The design of the flashing light 10 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 10 can be used as a warning signal to alert passing ships and aircraft to the presence of the platform, prevent accidental collisions, and ensure safety at sea. In emergency situations, such as severe weather or marine rescue operations, the flashing light 10 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 10 can provide the necessary light source to help workers work safely in dark environments.

[0044] In some embodiments, a climbing ladder 11 is provided between the top frame 1 and the bottom frame 2 , and both ends of the climbing ladder 11 are respectively connected to the top frame 1 and the bottom frame 2 , and the climbing ladder 11 extends in a vertical direction.

[0045] like Figure 1 and Figure 2 As shown, the climbing ladder 11 provides a convenient passage from the bottom frame to the top frame 101 for the workers, so that they can move up and down safely and quickly. With the climbing ladder 11, the workers can save time on going up and down the platform, thereby improving overall work efficiency. The design of the climbing ladder 11 usually includes handrails and anti-slip steps, which provides a safer climbing environment for the workers and reduces the risks during the climbing process.

[0046] In some embodiments, a support rod 12 is provided on at least one side of the climbing ladder 11, the support rod 12 extends in the vertical direction, and an L-shaped rod 13 is provided on the support rod 12. The L-shaped rod 13 includes a first rod body 1301 and a second rod body 1302, the first rod body 1301 is arranged perpendicular to the support rod 12, the second rod body 1302 is arranged parallel to the support rod 12 and spaced from the support rod 12, and the second rod body 1302 extends upward in the vertical direction.

[0047] The provision of the support rod 12 enhances the stability of the climbing ladder 11, especially in a marine environment, and can resist the influence of wind and waves, thereby ensuring the stability of the climbing ladder 11. The design of the L-shaped rod 13 as a mooring point for ships improves the practicality of the platform. The second rod body 1302 of the L-shaped rod 13 is provided parallel to the support rod 12, which can provide an additional fixing point for moored ships and increase the safety of mooring. The presence of the L-shaped rod 13 provides a clear mooring position for the ship, facilitating the berthing and unberthing operations of the ship. The provision of the L-shaped rod 13 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.
