Description

Technical Field

[0001] This invention relates to the field of photovoltaic power generation technology, and specifically to a floating, anti-sway photovoltaic power generation platform for marine applications. Background Technology

[0002] With the continuous growth of global energy demand and the increasing awareness of environmental protection, the development and utilization of renewable energy are receiving more and more attention. Photovoltaic power generation, as a clean and renewable energy form, has broad application prospects. In recent years, floating offshore photovoltaic power generation platforms, as an emerging energy utilization method, have gradually become a research hotspot. However, the marine environment is complex and changeable. During use, floating foundations are easily affected by wind, waves, and currents, resulting in significant swaying and poor stability. There is a risk of capsizing due to excessive tilt angles, seriously affecting the safe and stable operation of offshore photovoltaic power generation platforms. Summary of the Invention

[0003] This invention aims to at least partially solve one of the technical problems in related technologies. To this end, embodiments of this invention propose a floating, anti-sway photovoltaic power generation platform for offshore applications.

[0004] The present invention relates to a floating, anti-roll photovoltaic power generation platform for marine applications, comprising a top frame, a bottom frame, multiple first columns, pontoons, and photovoltaic panels. The top frame and the bottom frame are arranged at intervals in the vertical direction. Each of the top and bottom frames is a regular even-numbered polygonal frame with the same number of sides. In a projection plane orthogonal to the vertical direction, the vertices of the top frame and the bottom frame correspond one-to-one and coincide. The bottom frame includes a bottom border and multiple connecting rods, each connecting rod positioned between two opposite corners of the bottom border and being a hollow structure with open ends. The first columns are positioned between the vertices of the top frame and the corresponding vertices of the bottom frame. The bottom of each first column has a first water tank, and the two ends of the connecting rods are respectively connected to the first water tank of the first column. The pontoons are mounted on the bottom frame to provide buoyancy to the bottom frame. The photovoltaic panels are mounted on the top frame.

[0005] In some embodiments, a plurality of the connecting rods intersect and a second column is provided at the intersection position. The top of the second column is connected to the top frame, and the bottom of the second column has a second water tank. The connecting rods are connected to the second water tank.

[0006] In some embodiments, the second water tank has a water passage hole that communicates with the connecting rod on its wall, and a gravity gate is provided inside the second water tank. The gravity gate is adjustable in the vertical direction and is used to adjust the flow cross-sectional area of ​​the water passage hole.

[0007] In some embodiments, the second water tank is cylindrical, and the gravity gate includes a hydraulic rod and a gate. The hydraulic rod is located above the gate and connected to the second column. The hydraulic rod is used to drive the gate to move in the vertical direction. The gate is columnar, and the outer wall surface of the gate is adapted to cooperate with the inner wall surface of the second water tank.

[0008] In some embodiments, inclinometers are provided at both ends of the connecting rod, and the inclinometers are arranged parallel to the top frame. The inclinometers are used to monitor the tilt 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 third column is provided between the first column and the second column, the top of the third column being connected to the top frame, and the bottom of the third column being connected to the connecting rod.

[0011] 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.

[0012] In some embodiments, a first supporting diagonal brace is provided between the bottom of the third column and the top of the first column.

[0013] In some embodiments, a second supporting diagonal bar is provided between at least one end of the connecting rod and two sides adjacent to the bottom frame.

[0014] The floating, anti-sway photovoltaic power generation platform of this invention comprises a top frame, a bottom frame, a first column, pontoons, and photovoltaic panels. Both the top and bottom frames are regular even-numbered polygonal frames with the same number of sides, ensuring structural stability. The pontoons are mounted on the bottom frame, providing sufficient buoyancy to maintain the stability of the entire platform, allowing it to float on the sea surface. The connecting rod and the first water tanks at its two ends constitute anti-sway water tanks. When the floating, anti-sway photovoltaic power generation platform of this invention experiences significant swaying due to wind, waves, and currents, the water in the first water tanks connected to the two ends of the connecting rod flows through the connecting rod, thereby reducing the platform's sway and effectively minimizing the impact of wind, waves, and currents on the platform's sway, reducing the risk of capsizing, and improving the stability and safety of the photovoltaic power generation platform.

[0020] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0021] like Figures 1 to 3 As shown, the floating anti-sway photovoltaic power generation platform 100 of this invention includes a top frame 1, a bottom frame 2, multiple first columns 3, floats 4, and 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 regular even-numbered polygonal frame, and the top frame 1 and the bottom frame 2 have the same number of sides. In a projection plane orthogonal to the vertical direction, the vertices of the top frame 1 correspond one-to-one with the vertices of the bottom frame 2 and coincide. The bottom frame 2 includes a bottom border 201 and multiple connecting rods 202. The connecting rods 202 are located between two opposite corners of the bottom border 201 and are hollow structures with open ends. The first columns 3 are located between the vertices of the top frame 1 and the corresponding vertices of the bottom frame 2. The bottom of the first column 3 has a first water tank 301, and the two ends of the connecting rods 202 are respectively connected to the first water tank 301 of the first column 3. The pontoon 4 is installed on the bottom frame 2 to provide buoyancy to the bottom frame 2, and the photovoltaic panel 5 is installed on the top frame 1.

[0022] The floating anti-sway photovoltaic power generation platform 100 of this invention consists of a top frame 1, a bottom frame 2, a first column 3, pontoons 4, and photovoltaic panels 5. Both the top frame 1 and the bottom frame 2 are positive even-numbered polygonal frames with the same number of sides, ensuring structural stability. The pontoons 4 are mounted on the bottom frame 2, providing sufficient buoyancy to maintain the stability of the entire platform, allowing it to float on the sea surface. The connecting rod 202 and the first water tanks 301 at its two ends constitute anti-sway water tanks.

[0023] Specifically, when the offshore floating anti-sway photovoltaic power generation platform 100 of this embodiment of the invention is subjected to the action of sea wind, waves and currents, causing the platform to sway 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 anti-swaying the platform and suppressing the swaying of the platform. This can effectively reduce the impact of sea wind, waves and currents on the swaying of the platform, reduce the risk of platform capsizing, and improve the stability and safety of the photovoltaic power generation platform.

[0024] In some embodiments, a plurality of connecting rods 202 intersect and a second column 6 is provided at the intersection position. The top end of the second column 6 is connected to the top frame 1. The bottom of the second column 6 has a second water tank 601, and the connecting rods 202 are connected to the second water tank 601.

[0025] like Figure 2 and Figure 3 As shown, a second column 6 is provided at the intersection of 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. This ensures that each connecting rod 202 is located in the same plane, which helps to improve the structural strength of the bottom frame 2, thereby improving the platform's ability to resist sea waves and enhancing the platform's stability.

[0026] In some embodiments, a water passage hole 6011 communicating with the connecting rod 202 is provided on the wall of the second water tank 601. A gravity gate 7 is provided inside 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 passage hole 6011.

[0027] like Figure 3As shown, the floating anti-sway photovoltaic power generation platform 100 of this embodiment can control the opening of the water passage 6011 by adjusting the vertical position of the gravity gate 7, thereby regulating the flow cross-sectional area of ​​the connecting rod 202. When the water in the anti-sway tank oscillates at a certain period, the opening of the water passage 6011 can be controlled by the gravity gate 7 to adjust the oscillation period of the water in the anti-sway tank, so that the oscillation period of the water in the anti-sway tank is the same as the swaying period of the platform and has a phase difference. This ensures that the swaying torque generated by the wind, waves and currents on the platform is opposite to the torque generated by the water in the anti-sway tank during oscillation, thus achieving the best passive anti-sway effect of the anti-sway tank on the platform during swaying. In addition, it does not require much energy from the offshore photovoltaic generator to achieve the anti-sway effect, and has low start-up costs, high reliability, and low daily maintenance costs.

[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 connected to the second column 6. The hydraulic rod 701 is used to drive the gate 702 to move vertically. The gate 702 is columnar, and the outer wall surface of the gate 702 is adapted to mate with the inner wall surface of the second water tank 601.

[0029] The cylindrical second water tank 601 and the tightly fitted gate 702 design ensure more uniform water flow, contributing to improved overall platform stability. The gravity gate 7, driven by the hydraulic rod 701, allows for precise movement of the gate 702, enabling fine-tuning of the flow cross-sectional area of ​​the water passage 6011 and resulting in more precise platform stability control. Hydraulic systems typically have a fast response time, meaning the platform can quickly adapt to changes in external conditions, improving its dynamic stability. The application of a hydraulic system enhances the operational reliability of the gate 702, reducing the likelihood of mechanical failures. Precise control of the gate 702's opening degree reduces unnecessary energy loss and improves the system's energy efficiency.

[0030] In some embodiments, inclinometers 8 are provided at both ends of the connecting rod 202. The inclinometers 8 are arranged parallel to the top frame 1 and are used to monitor the tilt angle of the top frame 1 in the horizontal direction.

[0031] For example, such as Figure 3 As shown, the inclinometer 8 is located at the top of the connecting rod 202. By monitoring the change time of the inclinometer angle when the platform shakes in the horizontal direction, the shaking period of the platform can be quickly determined. This allows for rapid adjustment of the oscillation period of the water in the anti-sway tank to match the shaking period of the platform and maximize the anti-sway effect.

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

[0033] The floating anti-sway photovoltaic power generation platform 100 of this invention can quickly obtain the oscillation period of the water in the anti-sway tank by measuring the liquid level change time of the liquid level sensor 9, so as to quickly adapt to the platform's swaying period and achieve the best passive anti-sway effect when the floating platform is swaying.

[0034] Specifically, during adjustment, when the oscillation period of the water in the anti-sway tank is less than the swaying period of the platform, the flow cross-sectional area of ​​the water passage 6011 is reduced by gravity gate 7. When the oscillation period of the water in the anti-sway tank is greater than the swaying period of the platform, the flow cross-sectional area of ​​the water passage 6011 is increased by gravity gate 7. This ensures that the deviation between the oscillation period of the water in the anti-sway tank and the swaying period of the platform remains relatively small, thereby achieving the best passive anti-sway effect when the platform is swaying.

[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 placement of the third column 10 creates an additional support point, helping to distribute and withstand the pressure from wave and wind swaying, thus enhancing the overall stability of the platform. The third column 10 provides an extra support point, helping to maintain the structural strength of the platform and ensuring 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 distance between the third column 10 and the first column 3 and the second column 6 is equal, ensuring the symmetry of the structure, which helps to evenly distribute stress and reduce structural deformation. If one column or link fails, the other columns and links can still provide support. This design increases the redundancy of the structure and improves the reliability of the platform.

[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 support brace 11 provides an extra support point for the platform, helping to disperse the impact of external forces such as wind and waves on the platform, further enhancing the platform's structural strength. The presence of the first support brace 11 makes the connection between the first column 3 and the third column 10 more robust, helping to evenly distribute stress and reduce stress concentration. In extreme weather conditions such as typhoons and giant waves, the first support brace 11 can effectively increase the platform's resistance to wind and waves, reducing structural damage caused by external forces. The first support brace 11 helps reduce the platform's vibration in wind and waves, thereby reducing structural fatigue caused by continuous vibration. If a column or connecting rod 202 is damaged, the first support brace 11 can provide temporary support, ensuring that the platform does not lose stability due to localized damage. The installation of the first support brace 11 helps improve the platform's load-bearing capacity, enabling the platform to more safely install and operate larger-scale photovoltaic power generation systems.

[0041] In some embodiments, a second support brace 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 support brace 12 provides an extra support point for the platform, helping to disperse the impact of external forces such as wind and waves on the platform, thereby enhancing the overall stability of the platform. The presence of the second support brace 12 helps to evenly distribute stress, reducing stress concentration at the connection between the connecting rod 202 and the bottom frame 201, and improving the overall mechanical performance of the bottom frame 2 structure. In extreme weather conditions, such as typhoons and giant waves, the second support brace 12 can effectively enhance the platform's resistance to wind and waves, reducing the risk of structural damage. The second support brace 12 helps to reduce the platform's vibration and swaying in wind and waves, improving the platform's operational safety and comfort. The installation of the second support brace 12 helps to increase the platform's load-bearing capacity, enabling the platform to withstand larger loads, such as larger capacity photovoltaic panels 5.
