[0020] The 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.

[0021] like Figures 1 to 3 As shown, the offshore floating anti-roll photovoltaic power generation platform 100 of an embodiment of the present invention includes a top frame 1, a bottom frame 2, a plurality of first columns 3, a buoy 4 and a photovoltaic panel 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 regular even-numbered 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 bottom frame 2 includes a bottom frame 201 and a plurality of connecting rods 202. The connecting rod 202 is arranged between two opposite corners of the bottom frame 201. The connecting rod 202 is a hollow structure with openings at both ends. The first column 3 is arranged between the vertex of the top frame 1 and the corresponding vertex of the bottom frame 2. The bottom of the first column 3 has a first water tank 301. The two ends of the connecting rod 202 are respectively connected to the first water tank 301 of the first column 3. The buoy 4 is provided on the bottom frame 2 for providing buoyancy to the bottom frame 2 , and the photovoltaic panel 5 is provided on the top frame 1 .

[0022] The offshore floating, roll-stabilized photovoltaic power generation platform 100 according to an embodiment of the present invention comprises a top frame 1, a bottom frame 2, first columns 3, buoys 4, and photovoltaic panels 5. Both the top frame 1 and the bottom frame 2 are regular even-numbered polygons with the same number of sides, ensuring structural stability. The buoys 4 are mounted on the bottom frame 2, providing sufficient buoyancy to maintain the stability of the entire platform and enable it to float on the sea surface. The connecting rod 202 and the first water tanks 301 at its ends form the roll-stabilization water tanks.

[0023] Specifically, when the offshore floating anti-roll photovoltaic power generation platform 100 of an embodiment of the present invention is affected by offshore wind, waves and currents, causing the platform to shake significantly, the water in the first water tank 301 connected to the two ends of the connecting rod 202 will flow through the connecting rod 202, thereby playing a role in reducing the roll of the platform to suppress the roll of the platform, which can effectively reduce the impact of offshore wind, waves and currents on the roll of the platform, reduce the risk of the platform capsizing, and improve the stability and safety of the photovoltaic power generation platform.

[0024] In some embodiments, multiple connecting rods 202 intersect and are provided with second columns 6 at the intersections, the top ends of the second columns 6 being connected to the top frame 1. The bottom ends of the second columns 6 have a second water tank 601, and the connecting rods 202 are in communication with the second water tank 601.

[0025] like Figure 2 and Figure 3 As shown, a second column 6 is provided at the intersection of the multiple connecting rods 202. The top of the second column 6 is connected to the top frame 1, and the bottom is provided with a second water tank 601. In this way, the multiple connecting rods 202 intersect at the second water tank 601 and are transferred through the second water tank 601, which facilitates the arrangement of the connecting rods 202, so that each connecting rod 202 can be located in the same plane, which is beneficial to improving the structural strength of the bottom frame 2, thereby improving the platform's ability to resist offshore winds and waves and enhancing the platform's stability.

[0026] In some embodiments, a water hole 6011 connected to the connecting rod 202 is opened on the wall of the second water tank 601, and a gravity gate 7 is provided in the second water tank 601. The position of the gravity gate 7 is adjustable in the vertical direction. The gravity gate 7 is used to adjust the flow cross-sectional area of ​​the water hole 6011.

[0027] like Figure 3As shown, the offshore floating anti-rolling photovoltaic power generation platform 100 of the present invention can control the opening of the water hole 6011 by adjusting the vertical position of the gravity gate 7, thereby adjusting the flow cross-sectional area of ​​the connecting rod 202. When the water in the anti-rolling water tank oscillates at a certain period, the gravity gate 7 can be used to control the opening of the water hole 6011 to adjust the oscillation period of the water in the anti-rolling water tank. This ensures that the oscillation period of the water in the anti-rolling water tank is the same as the rolling period of the platform, but with a phase difference. This ensures that the rolling torque generated by the offshore wind, waves, and currents on the platform is opposite to the torque generated by the water in the anti-rolling water tank during oscillation, thereby achieving the optimal passive anti-rolling effect of the anti-rolling water tank on the platform during rolling. In addition, the anti-rolling effect can be achieved without requiring excessive energy from the offshore photovoltaic generator set, and the startup cost is low, the reliability is high, and the daily maintenance costs are low.

[0028] In some embodiments, the second water tank 601 is cylindrical, and the gravity gate 7 includes a hydraulic rod 701 and a gate 702. The hydraulic rod 701 is located above the gate 702 and is connected to the second column 6. The hydraulic rod 701 is used to drive the gate 702 to move vertically. The gate 702 is cylindrical, and the outer wall of the gate 702 is adapted to cooperate with the inner wall of the second water tank 601.

[0029] The cylindrical second water tank 601 and the tightly fitting gate 702 design make the water flow more uniform, which helps to improve the stability of the entire platform. The gravity gate 7 driven by the hydraulic rod 701 can achieve precise movement of the gate 702, thereby fine-tuning the flow cross-sectional area of ​​the water hole 6011, making the platform stability control more precise. The hydraulic system usually has a faster response speed, which means that the platform can quickly adapt to changes in external conditions and improve the dynamic stability of the platform. The application of the hydraulic system improves the operational reliability of the gate 702 and reduces the possibility of mechanical failure. By accurately controlling the opening degree of the gate 702, unnecessary energy loss can be reduced and the energy utilization efficiency of the system can be improved.

[0030] In some embodiments, both ends of the connecting rod 202 are provided with an inclinometer 8 , which is arranged parallel to the top frame 1 , and is used to monitor the inclination angle of the top frame 1 in the horizontal direction.

[0031] For example, Figure 3 As shown, the inclinometer 8 is provided at the top of the connecting rod 202. By monitoring the time of the inclination change when the platform shakes in the horizontal direction through the inclinometer 8, the shaking period of the platform can be quickly determined, so that the oscillation period of the water in the anti-rolling water tank can be quickly adjusted to adapt to the shaking period of the platform to maximize the anti-rolling effect.

[0032] In some embodiments, a liquid level sensor 9 is provided in the first water tank 301 , and the liquid level sensor 9 is used to monitor the liquid level in the first water tank 301 .

[0033] The offshore floating anti-roll photovoltaic power generation platform 100 of the embodiment of the present invention can quickly obtain the oscillation period of the water in the anti-roll water tank through the liquid level change time of the liquid level sensor 9, so as to quickly adapt to the platform's rolling period and achieve the best passive anti-roll effect when the floating platform is shaking.

[0034] Specifically, during adjustment, when the oscillation period of the water in the anti-rolling water tank is smaller than the rolling period of the platform, the flow cross-sectional area of ​​the water hole 6011 is reduced through the gravity gate 7; when the oscillation period of the water in the anti-rolling water tank is larger than the rolling period of the platform, the flow cross-sectional area of ​​the water hole 6011 is increased through the gravity gate 7, so that the deviation between the oscillation period of the water in the anti-rolling water tank and the rolling period of the platform is kept at a relatively small value, thereby achieving the best passive anti-rolling effect of the platform when shaking.

[0035] In some embodiments, a third column 10 is provided between the first column 3 and the second column 6 , the top of the third column 10 is connected to the top frame 1 , and the bottom of the third column 10 is connected to the connecting rod 202 .

[0036] The third column 10 provides an additional support point, helping to disperse and withstand the pressure from waves and wind, thereby enhancing the overall stability of the platform. The third column 10 provides an additional support point, helping to maintain the structural strength of the platform and ensure its safe operation during swaying.

[0037] In some embodiments, the distance between the first column 3 and the third column 10 is equal to the distance between the second column 6 and the third column 10 .

[0038] The third column 10 is equidistant from the first column 3 and the second column 6, ensuring structural symmetry and evenly distributing stress, thereby minimizing deformation. If damage occurs to a column or connecting rod, the remaining columns and connecting rods can still provide support. This design increases structural redundancy and enhances platform reliability.

[0039] In some embodiments, a first supporting diagonal rod 11 is provided between the bottom of the third column 10 and the top of the first column 3 .

[0040] like Figure 2As shown, the addition of the first supporting diagonal rod 11 provides an additional support point for the platform, which helps to disperse the impact of external forces such as wind and waves on the platform, and further enhances the structural strength of the platform. The presence of the first supporting diagonal rod 11 makes the connection between the first column 3 and the third column 10 more solid, helps to evenly distribute stress and reduce stress concentration. When encountering extreme weather conditions such as typhoons and huge waves, the first supporting diagonal rod 11 can effectively increase the platform's ability to resist wind and waves and reduce structural damage caused by external forces. The first supporting diagonal rod 11 helps to reduce the vibration of the platform in wind and waves, thereby reducing structural fatigue caused by continuous vibration. If a column or connecting rod 202 is damaged, the first supporting diagonal rod 11 can provide temporary support to ensure that the platform will not lose stability due to local damage. The provision of the first supporting diagonal rod 11 helps to improve the carrying capacity of the platform, allowing the platform to more safely install and operate larger-scale photovoltaic power generation systems.

[0041] In some embodiments, a second supporting diagonal rod 12 is provided between at least one end of the connecting rod 202 and two adjacent sides of the bottom frame 201 .

[0042] The addition of the second supporting diagonal rod 12 provides an additional support point for the platform, which helps to disperse the impact of external forces such as wind and waves on the platform, thereby enhancing the stability of the entire platform. The presence of the second supporting diagonal rod 12 helps to evenly distribute stress, reduce stress concentration at the connection between the connecting rod 202 and the bottom frame 201, and improve the overall mechanical properties of the bottom frame 2 structure. When encountering extreme weather conditions, such as typhoons and huge waves, the second supporting diagonal rod 12 can effectively enhance the platform's ability to resist wind and waves and reduce the risk of structural damage. The second supporting diagonal rod 12 helps to reduce the vibration and swaying of the platform in wind and waves, and improve the operational safety and comfort of the platform. The provision of the second supporting diagonal rod 12 helps to improve the platform's carrying capacity, allowing the platform to withstand larger loads, such as larger capacity photovoltaic panels 5.
