[0001] The invention relates to the technical field of photovoltaic power generation, and in particular to a strong wind-resistant floating offshore photovoltaic power generation platform. Background Art

[0002] At present, offshore photovoltaic power generation platforms mainly use column-type installation to fix photovoltaic panels on floating platforms. This traditional installation method meets the needs of offshore photovoltaic power generation to a certain extent, but there are the following problems in actual application: the offshore environment is complex and changeable, and extreme weather conditions such as strong winds and typhoons have a great impact on photovoltaic panels. Under the action of wind and waves, photovoltaic panels are prone to deformation or even rupture, seriously affecting their normal operation and power generation efficiency. In addition, the traditional column-type installation method is prone to damage to the connection between the column and the photovoltaic panel when the wind is strong, which in turn affects the stability of the entire platform.

[0003] In view of the above problems, it is necessary to develop a floating offshore photovoltaic power generation platform that is resistant to strong winds to meet the power generation needs in complex offshore environments. Summary of the invention

[0004] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. To this end, an embodiment of the present invention provides a strong wind-resistant floating offshore photovoltaic power generation platform.

[0005] The wind-resistant floating offshore photovoltaic power generation platform of the present invention includes a top frame, a bottom frame, a plurality of pontoons and a plurality of photovoltaic panels.

[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 plurality of buoys 4 and a plurality of photovoltaic panels 5. 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. The photovoltaic panels 5 are laid on the top frame 1, and two adjacent photovoltaic panels 5 are arranged at intervals to form a wind passage 6.

[0025] The floating offshore photovoltaic power generation platform 100 of the embodiment of the present invention can provide higher structural stability and effectively resist the impact of strong waves and typhoons by setting a polygonal frame and a column 3 structure. The intervals between adjacent photovoltaic panels 5 form a wind channel 6. When encountering extreme weather conditions such as strong waves and typhoons at sea, strong winds will flow through the wind channel 6 between adjacent photovoltaic panels 5, which can effectively reduce the direct impact of wind on the photovoltaic panel 5 and reduce wind loads, thereby reducing the risk of deformation and rupture of the photovoltaic panel 5. In addition, since the photovoltaic panel 5 is laid on the top frame 1, compared with the traditional column-type installation method, when the wind is strong, the problem of damage to the connecting part between the column and the photovoltaic panel 6 can also be avoided, thereby improving the stability of the entire platform. Therefore, the floating offshore photovoltaic power generation platform 100 of the embodiment of the present invention has the advantages of strong wind resistance and high operational stability.

[0026] In some embodiments, the spacing distance between two adjacent photovoltaic panels 5 is L, where 10 cm≤L≤15 cm.

[0027] like Figure 3 and Figure 4 As shown, appropriate spacing can reduce the wind resistance between adjacent photovoltaic panels 5, thereby reducing the pressure and vibration caused by wind and improving the wind resistance of the entire platform. The spacing of 10cm to 15cm can ensure that there is enough space between the photovoltaic panels 5 to reduce wind loads while maintaining the stability of the 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 photovoltaic panels 5 will be too large, resulting in structural damage to the photovoltaic panels 5 under the action of wind. 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.

[0028] 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 a space enclosed by the top frame 101. The mounting frame 102 includes a plurality of cross bars 1021 and a plurality of longitudinal bars 1022, wherein the plurality of cross bars 1021 are arranged at intervals in the first direction, and the cross bars 1021 extend along the second direction to connect with the top frame 101. The plurality of longitudinal bars 1022 are arranged at intervals in the second direction, and the longitudinal bars 1022 extend along the first direction to connect with the top frame 101. A plurality of mounting frames 103 are defined between the plurality of cross bars 1021 and the plurality of longitudinal bars 1022, and the photovoltaic panels 5 are fixed on the mounting frames 103, wherein the first direction is perpendicular to the second direction.

[0029] In the floating offshore photovoltaic power generation platform 100 of the embodiment of the present invention, the mounting frame 102 is provided with crisscrossing cross bars 1021 and longitudinal bars 1022 to define the mounting frame, and the photovoltaic panel 5 can be directly fixed on the mounting frame 103. The formation of the mounting frame 103 enables the photovoltaic panel 5 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 5 is directly mounted on the mounting frame 103, the use of supporting structures such as the columns 3 is reduced, which can save more space, make the layout of the entire platform more compact, and improve the space utilization rate. The simplified structure reduces protrusions such as the columns 3, 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 the columns 3 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 103 makes the replacement and maintenance of the photovoltaic panel 5 more convenient and quick, and only the frame part needs to be operated, and there is no need to make major adjustments to the entire structure.

[0030] In some embodiments, a plurality of first aisles 7 and a plurality of second aisles 8 are provided on the mounting frame 102, the plurality of first aisles 7 are arranged at intervals along the first direction, the first aisles 7 extend along the second direction to the top frame 101, and the plurality of second aisles 8 are arranged at intervals along the second direction, the second aisles 8 extend along the first direction to the top frame 101.

[0031] like Figure 3 and Figure 4As shown, the setting of the first walkway 7 and the second walkway 8 provides a safe and stable passage, so that the staff can move safely on the mounting frame 102, which is convenient for installation, maintenance and overhaul. The existence of the walkway enables the staff to quickly reach any position of the photovoltaic panel 5, improves work efficiency and shortens maintenance time. The walkway can provide a path for cables and other electrical wiring, helps to keep the wiring neat and orderly, and reduces the possibility of failure. The existence of the walkway makes it easier to monitor the platform. The staff can visually inspect the photovoltaic panel 5 on the walkway and find potential problems in time. 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 5 has enough installation area. The design of the walkway helps to isolate the space between the working area and the photovoltaic panel 5, reducing the interference of the staff on the photovoltaic panel 5 during operation.

[0032] In some embodiments, the top frame 101 forms a circular walkway, which is connected to the first walkway 7 and the second walkway 8.

[0033] 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 7 and the second walkway 8 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 5, 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.

[0034] Optionally, the first aisle 7 and / or the second aisle 8 has a plurality of air holes 9 arranged at intervals.

[0035] The provision of the air holes 9 allows wind to pass through the walkway, which helps to disperse and reduce the wind force acting on the photovoltaic panels 5, thereby reducing the overall pressure of the wind on the photovoltaic panels 5 and the platform. The wind passing through the air holes 9 can reduce the vibration caused by wind load, thereby reducing structural fatigue and potential damage risks, and improving the stability of the platform in wind and waves. The air holes 9 can optimize air flow and reduce the additional load caused by air turbulence.

[0036] The setting of the air holes 9 is not limited to a specific shape or size, and can be customized according to the structural requirements of the platform and the expected environmental conditions. By rationally designing the air holes 9, the use of materials can be reduced without affecting the stability of the platform, thereby reducing costs. The design of the air holes 9 should consider the following factors: the aperture needs to be large enough to effectively reduce the wind load, but at the same time, the overall stability of the platform must be ensured. The spacing between the air holes 9 needs to be optimized according to the wind speed and platform size to ensure the best wind passing effect. The shape of the air holes 9 can be circular, square or other streamlined designs to reduce wind resistance and eddy currents.

[0037] In some embodiments, a fence 10 is disposed at the edge of the top frame 101 , and the fence 10 is disposed around the top frame 101 .

[0038] like Figure 1 and Figure 5 As shown, the existence of the fence 10 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 10 is very important. The fence 10 can effectively prevent foreign objects (such as waves, floating objects, etc.) from directly hitting the photovoltaic panel 5, protecting the photovoltaic panel 5 from damage. The fence 10 provides a safer working environment for the workers, allowing them to focus more on maintenance and operation work and improve work efficiency.

[0039] In some embodiments, a plurality of flashing lights 11 are disposed on the fence 10 , and the plurality of flashing lights 11 are arranged at intervals along the circumference of the fence 10 .

[0040] The design of the flashing light 11 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 11 can serve 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 11 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 11 can provide the necessary light source to help workers work safely in dark environments.

[0041] In some embodiments, a climbing ladder 12 is provided between the top frame 1 and the bottom frame 2 , and both ends of the climbing ladder 12 are respectively connected to the top frame 1 and the bottom frame 2 , and the climbing ladder 12 extends in a vertical direction.

[0042] like Figure 1 and Figure 2As shown, the climbing ladder 12 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 12, the workers can save time on going up and down the platform, thereby improving overall work efficiency. The design of the climbing ladder 12 usually includes handrails and anti-slip steps, which provides a safer climbing environment for the workers and reduces the risks during the climbing process.

[0043] In some embodiments, at least one side of the climbing ladder 12 is provided with a support rod 13, and the support rod 13 extends in the vertical direction. The support rod 13 is provided with an L-shaped rod 14, and the L-shaped rod 14 includes a first rod body 1401 and a second rod body 1402, the first rod body 1401 is arranged perpendicular to the support rod 13, the second rod body 1402 is arranged parallel to the support rod 13 and spaced from the support rod 13, and the second rod body 1402 extends upward in the vertical direction.

[0044] The provision of the support rod 13 enhances the stability of the climbing ladder 12, especially in a marine environment, and can resist the influence of wind and waves, thereby ensuring the stability of the climbing ladder 12. The design of the L-shaped rod 14 as a mooring point for ships improves the practicality of the platform. The second rod body 1402 of the L-shaped rod 14 is provided parallel to the support rod 13, which can provide an additional fixing point for moored ships and increase the safety of mooring. The presence of the L-shaped rod 14 provides a clear mooring position for the ship, facilitating the berthing and unberthing operations of the ship. The provision of the L-shaped rod 14 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.
