However, the marine environment is complex and changeable. During use, floating foundations are prone to large shaking due to offshore wind, waves and currents, and have poor stability. There is a risk of capsizing due to excessive inclination, which seriously affects the safe and stable operation of offshore photovoltaic power generation platforms. Summary of the invention

[0003] 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 an offshore floating air pressure controlled anti-rolling photovoltaic power generation platform.

[0004] The offshore floating air pressure controlled anti-roll photovoltaic power generation platform of the present invention comprises a top frame, a bottom frame, a plurality of first columns, a buoy and a photovoltaic panel. The top frame and the bottom frame are arranged at intervals in the vertical direction, each of the top frame and the bottom frame is a regular even-numbered polygonal frame, and the top frame and the bottom frame have the same number of sides, and in a projection plane orthogonal to the vertical direction, the vertices of the top frame correspond to and coincide with the vertices of the bottom frame one by one, and the bottom frame comprises a bottom frame and a plurality of connecting rods, the connecting rods are arranged between two opposite corners of the bottom frame, and the connecting rods are hollow structures with openings at both ends;

[0005] The first column is arranged between the vertex of the top frame and the corresponding vertex of the bottom frame, the bottom of the first column has a first water tank, the two ends of the connecting rod are respectively connected with the first water tank of the first column, a first air pipe is arranged between the first water tanks of the two first columns opposite to each other at both ends of the connecting rod, a first control valve is arranged on the first air pipe, and the first control valve is used to control the flow cross-sectional area of ​​the first air pipe; the float is arranged on the bottom frame, and is used to provide buoyancy to the bottom frame; the photovoltaic panel is arranged on the top frame.

[0006] In some embodiments, the offshore floating air pressure controlled roll stabilization photovoltaic power generation platform of the embodiments of the present invention further includes an air pump, which is disposed on the bottom frame and connected to the first air pipe for conveying compressed gas into the first air pipe.

[0007] In some embodiments, a second control valve is provided between the air pump and the first air pipe, and the second control valve is used to control the flow rate of compressed gas delivered by the air pump to the first air pipe.

[0008] In some embodiments, both ends of the connecting rod are provided with inclinometers, the inclinometers are arranged parallel to the top frame, and the inclinometers are used to monitor the inclination angle of the top frame in the horizontal direction.

[0009] In some embodiments, a liquid level sensor is provided in the first water tank, and the liquid level sensor is used to monitor the liquid level height in the first water tank.

[0010] In some embodiments, a plurality of the connecting rods intersect and a second column is provided at the intersection, the top end of the second column is connected to the top frame, the bottom of the second column has a second water tank, and the connecting rod is connected to the second water tank.

[0011] In some embodiments, a third column is disposed between the first column and the second column, the top of the third column is connected to the top frame, and the bottom of the third column is connected to the connecting rod.

[0012] In some embodiments, the distance between the first column and the third column is equal to the distance between the second column and the third column.

[0015] In the offshore floating air pressure controlled anti-roll photovoltaic power generation platform of the embodiment of the present invention, if the first control valve is completely closed, the first air pipe cannot be connected to the air at the top of the first water tank at both ends of the connecting rod. When the water oscillates between the first water tanks at both ends of the connecting rod, the air at the top of the first water tank will give the water a large resistance, resulting in the inability to adjust the oscillation period of the water in the anti-roll water tank. Therefore, by controlling the opening of the first control valve, the first air pipe is connected to the air at the top of the first water tank at both ends of the connecting rod. When the water oscillates between the first water tanks at both ends of the connecting rod, the air at the top of the two first water tanks can be interconnected to reduce the resistance of the air at the top of the first water tank to the water, so as to change the oscillation period of the water in the anti-roll water tank. The oscillation period of the water in the anti-roll water tank is adapted to the rolling period of the platform and has a phase difference, so that the torque generated by the offshore wind, waves and current on the floating foundation is opposite to the torque generated by the water in the anti-roll water tank on the first anti-roll water tank when oscillating, thereby achieving the best passive anti-roll effect of the anti-roll water tank on the platform when shaking.

[0016] Therefore, when the offshore floating air pressure controlled anti-roll photovoltaic power generation platform of the embodiment of the present invention shakes, the opening of the first control valve is controlled to make the oscillation period of the water in the anti-roll water tank adapt to the rolling period of the platform and produce a phase difference, so as to achieve the best passive anti-roll effect of the platform when rolling. Therefore, when the offshore floating anti-roll photovoltaic power generation platform of the embodiment of the present invention is affected by the offshore wind, waves and currents, causing the platform to shake greatly, the anti-roll water tank can play a role in reducing the platform to suppress the shaking of the platform, which can effectively reduce the shaking effect of the offshore wind, waves and currents on the platform, reduce the risk of platform capsizing, and improve the stability and safety of the photovoltaic power generation platform.

DETAILED DESCRIPTION

[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] The offshore floating air pressure controlled anti-roll 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 buoy 6 and a photovoltaic panel 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 regular even 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 one by one. 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, and the connecting rod 202 is a hollow structure with openings at both ends.

[0024] The first column 3 is arranged between the vertex of the top frame 1 and the vertex corresponding to 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. A first air pipe 4 is arranged between the first water tanks 301 of the two first columns 3 opposite to each other at both ends of the connecting rod 202. The first air pipe 4 is provided with a first control valve 5. The first control valve 5 is used to control the flow cross-sectional area of ​​the first air pipe 4. The buoy 6 is arranged on the bottom frame 2 to provide buoyancy to the bottom frame 2. The photovoltaic panel 7 is arranged on the top frame 1.

[0025] The offshore floating air pressure controlled anti-roll photovoltaic power generation platform 100 of the embodiment of the present invention is composed of a top frame 1, a bottom frame 2, a first column 3, a buoy 6 and a photovoltaic panel 7. The top frame 1 and the bottom frame 2 are both regular even polygonal frames with the same number of sides, which ensures the stability of the structure. The buoy 6 is arranged on the bottom frame 2 to provide sufficient buoyancy to maintain the stability of the entire platform so that the platform can float on the surface of the sea. The connecting rod 202 and the first water tank 301 at both ends thereof constitute an anti-roll water tank.

[0026] Specifically, if the first control valve 5 is completely closed, the first air pipe 4 cannot communicate with the air at the top of the first water tank 301 at both ends of the connecting rod 202. When the water oscillates between the first water tanks 301 at both ends of the connecting rod 202, the air at the top of the first water tank 301 will give the water a greater resistance, resulting in the inability to adjust the oscillation period of the water in the anti-rolling water tank. Therefore, by controlling the opening of the first control valve 5, the first air pipe 4 is connected to the air at the top of the first water tank 301 at both ends of the connecting rod 202. When the water oscillates between the first water tanks 301 at both ends of the connecting rod 202, the air at the top of the two first water tanks 301 can communicate with each other, so as to reduce the resistance of the air at the top of the first water tank 301 to the water, so as to change the oscillation period of the water in the anti-rolling water tank. The oscillation period of the water in the anti-rolling water tank is adapted to the rolling period of the platform and has a phase difference, so that the torque generated by the offshore wind, waves and currents on the floating foundation is opposite to the torque generated by the water in the anti-rolling water tank on the first anti-rolling water tank when oscillating, thereby achieving the best passive anti-rolling effect of the anti-rolling water tank on the platform when shaking.

[0027] Therefore, when the offshore floating air pressure controlled anti-roll photovoltaic power generation platform 100 of the embodiment of the present invention shakes, the opening of the first control valve 5 is controlled to make the oscillation period of the water in the anti-roll water tank adapt to the rolling period of the platform and produce a phase difference, so as to achieve the best passive anti-roll effect of the platform when rolling. Therefore, when the offshore floating anti-roll photovoltaic power generation platform 100 of the embodiment of the present invention is affected by the offshore wind, waves and currents, causing the platform to shake greatly, the anti-roll water tank can play a role in reducing the platform to suppress the shaking of the platform, which can effectively reduce the shaking effect of the offshore wind, waves and currents on the platform, reduce the risk of the platform capsizing, and improve the stability and safety of the photovoltaic power generation platform.

[0028] In some embodiments, the offshore floating air pressure controlled anti-roll photovoltaic power generation platform 100 of the embodiment of the present invention further includes an air pump 8 , which is disposed on the bottom frame 2 and connected to the first air pipe 4 for conveying compressed gas into the first air pipe 4 .

[0029] When the first control valve 5 is opened, the compressed gas entering the first air pipe 4 can enter the top of the first water tank 301, so that the gas at the top of the first water tank 301 has a certain pressure, so that when the anti-rolling water tank shakes, the gas at the top of the first water tank 301 can flow quickly through the first air pipe 4, so as to improve the efficiency of regulating the oscillation period of the water in the anti-rolling water tank.

[0030] Optionally, a second control valve 9 is provided between the air pump 8 and the first air pipe 4, and the second control valve 9 is used to control the flow rate of compressed gas delivered by the air pump 8 into the first air pipe 4. By adjusting the opening of the second control valve 9, the flow rate of the air pump 8 entering the first air pipe 4 can be adjusted, so as to facilitate precise adjustment, which is conducive to improving the adjustment efficiency.

[0031] In some embodiments, both ends of the connecting rod 202 are provided with an inclinometer 10, and the inclinometer 10 is arranged parallel to the top frame 1, and the inclinometer 10 is used to monitor the inclination angle of the top frame 1 in the horizontal direction.

[0032] For example, Figure 3 As shown, the inclinometer 10 is arranged at the top of the connecting rod 202. The inclinometer 10 monitors the tilt change time when the platform shakes in the horizontal direction, so as to quickly determine the shaking period of the platform, so as to quickly adjust the oscillation period of the water in the anti-rolling water tank to adapt to the shaking period of the platform and maximize the anti-rolling effect.

[0033] In some embodiments, a liquid level sensor 11 is provided in the first water tank 301 , and the liquid level sensor 11 is used to monitor the liquid level height in the first water tank 301 .

[0034] The offshore floating air pressure controlled 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 11, so as to quickly adapt to the shaking period of the platform and achieve the best passive anti-roll effect of the floating platform when shaking.

[0035] In some embodiments, multiple connecting rods 202 intersect and a second column 12 is provided at the intersection, the top of the second column 12 is connected to the top frame 1, the bottom of the second column 12 has a second water tank 1201, and the connecting rod 202 is connected to the second water tank 1201.

[0036] like Figure 2 and Figure 3 As shown, a second column 12 is provided at the intersection of multiple connecting rods 202, the top of the second column 12 is connected to the top frame 1, and the bottom is provided with a second water tank 1201. In this way, multiple connecting rods 202 intersect at the second water tank 1201 and are transferred through the second water tank 1201, 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 ability of the platform to resist wind and waves at sea and enhancing the stability of the platform.

[0037] In some embodiments, a third column 13 is disposed between the first column 3 and the second column 12 , the top of the third column 13 is connected to the top frame 1 , and the bottom of the third column 13 is connected to the connecting rod 202 .

[0038] The third column 13 provides an additional support point, which helps to disperse and withstand the pressure from waves and wind shaking, and enhances the overall stability of the platform. The third column 13 provides an additional support point, which helps to maintain the structural strength of the platform and ensure the safety of the platform during the swaying process.

[0039] In some embodiments, the distance between the first column 3 and the third column 13 is equal to the distance between the second column 12 and the third column 13 .

[0040] The third column 13 is equidistant from the first column 3 and the second column 12, ensuring the symmetry of the structure, helping to evenly distribute stress and reduce structural deformation. If a column is damaged, the other columns can still provide support. This design increases the redundancy of the structure and improves the reliability of the platform.

[0041] In some embodiments, a first supporting diagonal rod 14 is provided between the bottom of the third column 13 and the top of the first column 3 .

[0042] like Figure 2 As shown, the addition of the first support diagonal rod 14 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 support diagonal rod 14 makes the connection between the first column 3 and the third column 13 more solid, helps to evenly distribute stress and reduce stress concentration. When encountering extreme weather conditions such as typhoons and huge waves, the first support diagonal rod 14 can effectively increase the platform's wind and wave resistance and reduce structural damage caused by external forces. The first support diagonal rod 14 helps to reduce the vibration of the platform in the wind and waves, thereby reducing structural fatigue caused by continuous vibration. If a column or connecting rod 202 is damaged, the first support diagonal rod 14 can provide temporary support to ensure that the platform will not lose stability due to local damage. The setting of the first support diagonal rod 14 helps to improve the carrying capacity of the platform, so that the platform can more safely install and operate a larger-scale photovoltaic power generation system.

[0043] In some embodiments, a second supporting diagonal rod 15 is disposed between at least one end of the connecting rod 202 and two adjacent sides of the bottom frame 201 .

[0044] The addition of the second supporting diagonal rod 15 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 15 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 15 can effectively enhance the platform's ability to resist wind and waves and reduce the risk of structural damage. The second supporting diagonal rod 15 helps to reduce the vibration and swaying of the platform in wind and waves, and improves the operating safety and comfort of the platform. The provision of the second supporting diagonal rod 15 helps to improve the platform's carrying capacity, allowing the platform to withstand larger loads, such as larger capacity photovoltaic panels 7.
