[0007] The adjustment component includes a sealing plate and a telescopic motor. The sealing plate is arranged perpendicular to the vertical direction. The sealing plate stops at the bottom wall of the first water tank in the vertical direction. The telescopic motor is connected to the sealing plate to drive the sealing plate to extend and retract to block the opening.

[0008] In some embodiments, the telescopic motor and the sealing plate are both arranged outside the first water bin, and the sealing plate abuts upward against the outer bottom wall of the first water bin.

[0009] In some embodiments, a slide groove extending along the telescopic direction of the telescopic motor is provided on the outer bottom wall of the first water bin, and a slider is provided on the sealing plate, and the slider is slidably engaged with the slide groove.

[0010] 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; and / or

[0011] 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.

DETAILED DESCRIPTION

[0025] 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.

[0026] like Figures 1 to 4As shown, the offshore floating open controlled anti-roll photovoltaic power generation platform of the 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 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, and the bottom frame 2 includes a bottom frame 201 and a plurality of connecting rods 202, and the connecting rods 202 are arranged between two opposite corners of the bottom frame 201.

[0027] The first column 3 is arranged between the vertex of the top frame 1 and the corresponding vertex of the bottom frame 2, and the two ends of the connecting rod 202 are respectively connected to the first column 3. The bottom of the first column 3 has a first water tank 301, and the bottom wall of the first water tank 301 has an opening 3011 for seawater to enter. The buoy 4 is arranged on the bottom frame 2 to provide buoyancy to the bottom frame 2, and the photovoltaic panel 5 is arranged on the top frame 1.

[0028] 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 4 and a photovoltaic panel 5. 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 4 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 water. The first water tank 301 connected at both ends of the connecting rod 202 and the seawater form an anti-roll water tank.

[0029] Specifically, when the offshore floating air pressure controlled anti-roll photovoltaic power generation platform 100 of the embodiment of the present invention is in use, when the platform is greatly shaken by offshore wind, waves and currents, seawater enters the first water tank 301 through the opening 3011 on the bottom wall of the first water tank 301, and the seawater in the first water tank 301 at both ends of the connecting rod 202 is connected through the sea, so that the seawater oscillates between the first water tanks 301 at both ends of the connecting rod 202. Thus, the shaking moment generated by offshore wind, waves and currents on the platform is opposite to the pitching moment generated by the seawater in the anti-roll water tank on the anti-roll water tank when oscillating, thereby achieving the best passive anti-roll effect of the first anti-roll water tank on the platform when rolling.

[0030] Therefore, when the offshore floating air pressure controlled anti-roll photovoltaic power generation platform 100 of the embodiment of the present invention is affected by offshore wind, waves and currents and causes the platform to shake greatly, the anti-roll water tank can play a role in reducing the shaking of the platform to suppress the shaking of the platform, which can effectively reduce the shaking impact of 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.

[0031] In some embodiments, an adjustment component 6 is provided on the bottom wall of the first water tank 301, and the adjustment component 6 is used to adjust the size of the opening 3011. The adjustment component 6 includes a sealing plate 601 and a telescopic motor 602, the sealing plate 601 is arranged perpendicular to the vertical direction, the sealing plate 601 abuts against the bottom wall of the first water tank 301 in the vertical direction, and the telescopic motor 602 is connected to the sealing plate 601 to drive the sealing plate 601 to extend and retract to block the opening 3011.

[0032] like Figure 3 and Figure 4 As shown, the offshore floating air pressure controlled anti-roll photovoltaic power generation platform 100 of the embodiment of the present invention adjusts the opening of the opening 3011 on the bottom wall of the first water tank 301 by the adjusting component 6 to control the flow rate of seawater entering and exiting the first water tank 301, so as to regulate the oscillation period of the seawater in the anti-roll water tank, so that the oscillation period of the seawater in the anti-roll water tank adapts to the rolling period of the platform and has a phase difference, thereby achieving the best passive anti-roll effect of the platform when rolling.

[0033] In some embodiments, the telescopic motor 602 and the sealing plate 601 are both disposed outside the first water tank 301 , and the sealing plate 601 abuts upward against the outer bottom wall of the first water tank 301 .

[0034] Since the sealing plate 601 and the telescopic motor 602 are both located outside the first water tank 301, this reduces the damage to the equipment when a failure or leakage occurs inside the first water tank 301, thereby improving the safety of the entire system. The sealing plate 601 and the telescopic motor 602 are arranged outside the water tank, making maintenance and overhaul work more convenient. The staff can inspect and repair the equipment without entering the first water tank 301, reducing the operational risk. Placing the sealing plate 601 and the telescopic motor 602 outside the first water tank 301 helps to simplify the structural design of the first water tank 301. The complexity of the internal structure of the first water tank 301 can be reduced, and the stability and reliability of the overall structure can be improved. Setting the sealing plate 601 outside the first water tank 301 can reduce the space occupied inside the first water tank 301 and provide more space for the vibration of water in the first water tank 301.

[0035] In some embodiments, a slide groove 3012 extending along the telescopic direction of the telescopic motor 602 is provided on the outer bottom wall of the first water tank 301 , and a slider 603 is provided on the sealing plate 601 , and the slider 603 can slidably cooperate with the slide groove 3012 .

[0036] like Figure 4As shown, the design of the slide groove 3012 and the slider 603 allows the sealing plate 601 to move precisely along the slide groove 3012 under the drive of the telescopic motor 602, ensuring that the sealing plate 601 can accurately align with the opening 3011 of the water tank or the closed position. The sliding design of the slider 603 and the slide groove 3012 can reduce the friction and wear between the two, thereby extending the service life of the sealing plate 601 and the slide groove 3012. The sliding movement of the slider 603 in the slide groove 3012 can provide a more stable and smooth movement, reduce the jitter or jump that may occur during the telescopic process, and improve the overall stability of the system.

[0037] In some embodiments, both ends of the connecting rod 202 are provided with an inclinometer 7, and the inclinometer 7 is arranged parallel to the top frame 1. The inclinometer 7 is used to monitor the inclination angle of the top frame 1 in the horizontal direction.

[0038] For example, Figure 3 and Figure 4 As shown, the inclinometer 7 is arranged at the top of the connecting rod 202. The inclinometer 7 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.

[0039] In some embodiments, a liquid level sensor 8 is provided in the first water tank 301 , and the liquid level sensor 8 is used to monitor the liquid level height in the first water tank 301 .

[0040] 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 8, 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.

[0041] In some embodiments, a plurality of connecting rods 202 intersect and a second column 9 is disposed at the intersection, the top end of the second column 9 is connected to the top frame 1 , and the connecting rod 202 is connected to the second column 9 .

[0042] like Figure 2 and Figure 3 As shown, a second column 9 is provided at the intersection of multiple connecting rods 202, and the top of the second column 9 is connected to the top frame 1, so that the multiple connecting rods 202 intersect at the second column 9, which is convenient for arranging 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 offshore wind and waves and enhancing the stability of the platform.

[0043] In some embodiments, a third column 10 is disposed between the first column 3 and the second column 9 , 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 .

[0044] The third column 10 forms 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 10 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.

[0045] In some embodiments, the distance between the first column 3 and the third column 10 is equal to the distance between the second column 9 and the third column 10 .

[0046] The third column 10 is equidistant from the first column 3 and the second column 9, 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.

[0047] 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 .

[0048] As shown in the figure, the addition of the first support 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 support 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 support diagonal rod 11 can effectively increase the platform's wind and wave resistance and reduce structural damage caused by external forces. The first support diagonal rod 11 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 11 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 11 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.

[0049] In some embodiments, a second supporting diagonal rod 12 is provided between at least one end of the connecting rod 202 and two sides adjacent to the bottom frame 201. The addition of the second supporting diagonal rod 12 provides an additional support point for the platform, which helps to disperse the influence 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 wind and wave resistance 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 improves the operating safety and comfort of the platform. The setting of the second supporting diagonal rod 12 helps to improve the carrying capacity of the platform, so that the platform can withstand a larger load, such as a photovoltaic panel 5 with a larger capacity.
