[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 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 first buoys 4, a mounting frame 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. The top frame 1 includes a plurality of first connecting rods 101 connected end to end, and the bottom frame 2 includes a plurality of second connecting rods 201 connected end to end. A first column 3 is provided between the vertices of the top frame 1 and the corresponding vertices of the bottom frame 2, and a scale line is provided on the outer wall surface of the first column 3 for monitoring the position depth of the first column 3 in the seawater. At least one first buoy 4 is sleeved on each second connecting rod 201 for providing buoyancy for the bottom frame 2. The mounting frame is arranged in the space enclosed by the top frame 1 and connected to the top frame 1, and the photovoltaic panel 6 is arranged on the mounting frame.

[0024] When the floating offshore photovoltaic power generation platform 100 of the embodiment of the present invention is in use, when the first buoy 4 on the bottom frame 2 fails, the platform tilts due to the uneven buoyancy. By setting scale lines on the outer wall of the first column 3, the position depth of the first column 3 in the seawater can be easily monitored, so that maintenance personnel can quickly and accurately determine the position of the column, which is convenient for replacing or maintaining the failed first buoy 4, ensuring the stable operation of the platform. Therefore, the floating offshore photovoltaic power generation platform 100 of the embodiment of the present invention is convenient for monitoring the buoyancy state and stability of the platform by setting scale lines on the first column 3, avoiding the platform from tilting due to the uneven buoyancy, and improving the working reliability and stability of the platform.

[0025] In some embodiments, a camera is disposed on at least one of the top frame 1 and the mounting frame, and the shooting direction of the camera is set toward the position of the scale line on the first column 3 .

[0026] The installation of the camera enables real-time monitoring of the scale line on the first column 3, and automatically records the position change data of the column. These data can be used to analyze the buoyancy and stability of the platform, further improving the automation and intelligence level of monitoring. Through the video monitoring system, an early warning threshold can be set. Once the position change of the column exceeds the predetermined range, the system will automatically issue an alarm and promptly notify the maintenance personnel to take measures to prevent the platform from tilting or being damaged more seriously. The installation of the camera enables the operation status of the platform to be remotely monitored. The management personnel can view the status of each platform in real time in the control center, and conduct remote management and adjustment, thereby improving management efficiency and response speed. When maintenance or repair is required, the camera can help the maintenance personnel locate the problem area, reduce the time of on-site inspection, and improve the efficiency of maintenance work. The marine environment is complex and changeable. The monitoring of the camera helps to timely detect floating objects, obstacles or other objects that may cause damage to the platform, so as to take avoidance measures in advance to ensure the safety of personnel and equipment.

[0027] In some embodiments, the second connecting rod 201 is provided with a plurality of first baffles 7 spaced apart along the axial direction thereof, and at least one first baffle 7 is provided on both sides of the first buoy 4 .

[0028] First, the first baffle 7 can stop the first buoy 4 and prevent it from moving in the axial direction of the second connecting rod 201 to ensure that the buoyancy of the platform is evenly distributed. In addition, the first baffle 7 can also effectively reduce the direct impact of the water flow on the second connecting rod 201, reduce the vibration and shaking caused by the water flow, and thus improve the overall stability of the platform. In addition, the setting of the first baffle 7 helps to disperse the water flow and reduce the accumulation of the water flow on the second connecting rod 201, which helps to reduce the impact force of the water flow and protect the connecting rod from damage. In the marine environment, there may be a risk of floating objects or other objects hitting the platform. The first baffle 7 can play a certain buffering role and reduce the possibility of objects directly hitting the second connecting rod 201. The setting of the first baffle 7 can also increase the effective buoyancy area of ​​the second connecting rod 201, thereby increasing the buoyancy of the entire platform, so that it can better adapt to different sea conditions.

[0029] The first baffle 7 provides an additional protective layer for the first buoy 4, which can prevent or reduce the direct impact of waves, floating objects, etc. on the buoy. The setting of the first baffle 7 helps to improve the fluid dynamics around the first buoy 4, reduce the resistance of the fluid to the first buoy 4, and improve the movement performance of the platform in the water. The first baffle 7 is combined with the structure of the first buoy 4 to improve the structural strength of the buoy and make it more durable.

[0030] In some embodiments, a second column 8 is provided between the first connecting rod 101 and the second connecting rod 201 opposite to it in the vertical direction, a second buoy 9 is sleeved on the second column 8, the bottom of the second buoy 9 is stopped on the second connecting rod 201, and a second baffle 10 is provided on the second column 8 and located above the second buoy 9, and the second baffle 10 is used to stop the second buoy 9 downward.

[0031] When the first buoy 4 fails, the second buoy 9 can immediately provide temporary buoyancy support to ensure that the platform will not tilt or sink due to the failure of the buoy, thereby maintaining the stability of the platform. The setting of the second buoy 9 and the second baffle 10 increases the safety factor of the platform, and can effectively prevent accidents caused by the failure of a single or multiple buoys on the platform even in harsh marine environments. When the first buoy 4 fails, the second buoy 9 can quickly provide support, winning valuable repair time for maintenance personnel, reducing downtime, and improving the operating efficiency of the platform. The design of the second buoy 9 and the second baffle 10 makes maintenance work more convenient. When the first buoy 4 needs to be repaired or replaced, maintenance personnel can directly operate the first buoy 4 without worrying about the stability of the platform. The design of the second buoy 9 and the second baffle 10 can be adjusted according to actual needs. For example, according to different sea conditions and load requirements, the number and position of the second buoy 9 can be adjusted to adapt to different working conditions.

[0032] In some embodiments, the first column 3 includes a large diameter section 301, a variable diameter section 302 and a small diameter section 303 which are connected in sequence from bottom to top, the diameter of the large diameter section 301 is larger than the diameter of the small diameter section 303, the cross-sectional area of ​​the variable diameter section 302 gradually decreases from bottom to top, and the second connecting rod 201 is connected to the large diameter section 301.

[0033] The floating offshore photovoltaic power generation platform 100 of the embodiment of the present invention is designed in sections. While maintaining the overall strength, the first column 3 can optimize the use of materials according to the needs and stress conditions of different parts, reduce the overall weight, and improve the rationality of the structure. The large diameter section 301 is located at the bottom, which helps to resist the impact force brought by the flow of seawater, and the design of the variable diameter section 302 and the small diameter section 303 can reduce the resistance of the water flow to the column, reduce the impact of fluid dynamics, and improve the stability of the platform. The combination of the large diameter section 301 and the small diameter section 303 increases the sinking resistance of the first column 3 in the seawater, helps to improve the stability of the column and prevent the first column 3 from shaking in the seawater. The design of the variable diameter section 302 makes the force of the column more uniform, reduces stress concentration, and thus extends the service life of the first column 3. By using different diameters in different sections, materials can be used more efficiently and material waste can be reduced. The second connecting rod 201 is connected to the large diameter section 301, and the larger contact area of ​​the large diameter section 301 can be used to provide a more stable connection, thereby enhancing the stability of the overall structure.

[0034] In some embodiments, the large diameter section 301 is provided with a first support plate 11 and a second support plate 12 which are arranged opposite to each other, a hinge shaft 13 is provided between the first support plate 11 and the second support plate 12, a hinge 14 is rotatably provided on the hinge shaft 13, and a connecting through hole 1401 is provided on the hinge 14, and the connecting through hole 1401 is used to connect the anchor chain.

[0035] The design of the hinge shaft 13 and the hinge 14 allows the connection between the anchor chain and the first column 3 to have a certain degree of flexibility, while maintaining the stability of the connection to prevent excessive stress caused by waves and wind. The rotatability of the hinge 14 allows the anchor chain to be adjusted according to changes in waves and wind, reducing the impact force on the first column 3 and improving the adaptability and survivability of the platform in severe sea conditions. The setting of the connecting through hole 1401 makes the connection of the anchor chain more convenient, and maintenance personnel can quickly connect or disconnect the anchor chain with the hinge 14, thereby improving maintenance efficiency. Through the hinge design, the load on the column caused by the change of the anchor chain can be reduced, thereby reducing structural fatigue and increasing the service life of the first column 3.

[0036] In some embodiments, a third buoy 15 is sleeved on the small diameter section 303 , and a third baffle 16 is provided on the small diameter section 303 and located above the third buoy 15 . The third baffle 16 is used to stop the third buoy 15 downward.

[0037] When the first buoy 4 fails, the third buoy 15 can immediately provide temporary buoyancy support to ensure that the platform will not tilt or sink due to the failure of the first buoy 4, thereby maintaining the stability of the platform. The provision of the third buoy 15 and the third baffle 16 increases the safety factor of the platform, and can effectively prevent accidents caused by the failure of a single or multiple buoys on the platform even in harsh offshore environments. When the first buoy 4 fails, the third buoy 15 can quickly provide support, winning valuable repair time for maintenance personnel, reducing downtime, and improving the operating efficiency of the platform. The design of the third buoy 15 and the third baffle 16 makes maintenance work more convenient. When the first buoy 4 needs to be repaired or replaced, maintenance personnel can directly operate the first buoy 4 without having to worry about platform stability issues.

[0038] Optionally, the third buoy 15 is located above the second buoy 9 .

[0039] Increased buoyancy: The addition of the third buoy 15 can provide additional buoyancy and further enhance the stability of the platform, especially in severe sea conditions. When the first buoy 4 fails, the second and third buoys 15 can jointly provide sufficient buoyancy support. By providing multiple layers of buoys, buoyancy support can be provided at different water level heights, so that the platform can maintain balance in different sea conditions and adapt to changes in water levels. The third buoy 15 serves as a backup buoy and provides additional safety. In the event that both the first buoy 4 and the second buoy 9 fail, the third buoy 15 can provide the necessary buoyancy to ensure that the platform does not sink. The presence of the third buoy 15 can increase the overall wind and wave resistance of the platform, reduce the tilt and sway caused by the impact of waves, and improve the stability of the platform in the offshore environment.

[0040] In some embodiments, the diameter of the large diameter section 301 is D, and the diameter of the small diameter section 303 is d, wherein 2.5≤D / d≤3.5.

[0041] For example, the value of D / d is 3. This diameter ratio design helps to optimize the structure of the column, so that the column can distribute materials according to the force requirements of different parts while maintaining sufficient strength, thereby reducing the overall weight and improving the utilization efficiency of materials. The large diameter section 301 is located at the bottom and can withstand greater pressure and impact force, while the small diameter section 303 is located at the top, which helps to reduce the resistance of seawater flow to the column, making the force of the entire column more uniform. The size ratio design of the large diameter section 301 and the small diameter section 303 helps to improve the stability of the column, especially in deep sea or harsh sea conditions. This design can effectively resist the force of waves and fluids. The appropriate proportional relationship can reduce the fluid resistance of the column in seawater, reduce the impact of fluid dynamics, thereby reducing energy loss and improving the operating efficiency of the platform. By adjusting the D / d ratio, different seabed conditions and sea conditions can be adapted. For example, for deeper waters or stronger currents, a larger D / d ratio can be selected to increase stability. A reasonable diameter ratio can reduce unnecessary material use, thereby reducing manufacturing costs, and is also convenient for manufacturing and maintenance. Appropriate proportion design helps reduce fatigue damage caused by waves, currents and other factors, and prolongs the service life of the columns. Such a proportion relationship is easy to implement in engineering practice, convenient for construction and maintenance, and can also be adjusted according to actual conditions.

[0042] In some embodiments, the length of the large diameter section 301 is L1, the length of the reduced diameter section 302 is L2, and the length of the small diameter section 303 is L3, wherein 1≤L3 / (L1+L2)≤2.

[0043] For example, the value of L3 / (L1+L2) is 1.5. This length ratio design helps to ensure that the various parts of the first column 3 have a suitable ratio so as to achieve good mechanical properties and stability while maintaining structural strength. The shorter design of the small diameter section 303 helps to reduce the fluid resistance of seawater to the column, while the longer design of the large diameter section 301 and the variable diameter section 302 can provide greater stability and wind and wave resistance. By adjusting the length ratio of each diameter section, the force distribution of the column can be optimized so that different forces can be withstand at different heights of the column, thereby reducing stress concentration. The longer large diameter section 301 and the variable diameter section 302 help the column better adapt to different types of seabed conditions, such as soft or hard seabeds, and improve the contact stability between the column and the seabed. The shorter small diameter section 303 helps to reduce the impact of vortices generated by the flow of seawater on the column, thereby reducing the potential damage to the column caused by vortex-induced vibration. By optimizing the design, material consumption can be reduced, costs can be reduced, and the performance and reliability of the column can be guaranteed.

[0044] Therefore, by setting the ratio range between the length L1 of the large diameter section 301, the length L2 of the variable diameter section 302 and the length L3 of the small diameter section 303 to 1≤L3 / (L1+L2)≤2, the overall performance and economy of the floating offshore photovoltaic power generation platform 100 can be improved while ensuring the stability and reliability of the column structure.
