Photovoltaic power generation, as a clean and renewable energy form, has broad application prospects. In recent years, offshore photovoltaic power generation, as an emerging energy utilization method, has gradually become a research hotspot. However, due to the high cost of floating offshore photovoltaic power generation platforms, in order to fully utilize the platform area and improve photovoltaic power generation efficiency, photovoltaic panels are laid flat across the entire platform. However, when photovoltaic panels are damaged and cannot be used during use, replacement becomes difficult. Summary of the Invention

[0003] This invention aims to at least partially address one of the technical problems in related technologies. To this end, embodiments of this invention propose a floating offshore photovoltaic power generation platform that facilitates the replacement of photovoltaic panels from below.

[0004] The present invention provides a floating offshore photovoltaic power generation platform for easy replacement of photovoltaic panels from below, comprising a top frame, a bottom frame, a support beam, a moving assembly, a lifting assembly, and a basket. The top frame and the bottom frame are arranged at intervals in the vertical direction. The top frame is used to install photovoltaic panels, and a central column is provided between the center of the top frame and the bottom frame. The support beam is located between the top frame and the bottom frame and is parallel to the top frame. The support beam includes a first end and a second end, the first end being rotatably connected to the top of the central column, and the second end extending to the edge of the top frame. The moving assembly is movably connected to the support beam along its length. The lifting assembly is located on the moving assembly and connected to the basket for raising and lowering the basket.

[0005] In some embodiments, a first motor is provided on the support beam, a first gear is provided on the output shaft of the first motor, and a second gear is fitted on the central column, with the first gear meshing with the second gear.

[0006] In some embodiments, the moving component includes a slider and a driving component. The slider is slidably connected to the support beam along the length direction of the support beam. The driving component is driven to the slider and is used to drive the slider to slide. The slider is connected to the lifting component.

[0007] In some embodiments, the support beam has a first support plate and a second support plate at both ends, the slider has a threaded through hole extending along the length of the support beam, the drive assembly includes a second motor and a screw, the screw passes through the threaded through hole and is rotatably connected to the first support plate and the second support plate at both ends, the screw is threadedly engaged with the threaded through hole, and the second motor is used to drive the screw to rotate.

[0008] In some embodiments, the lifting assembly includes a third motor, a drum, and a hoisting rope. The drum is rotatably mounted on the slider. The third motor drives the drum to rotate. One end of the hoisting rope is wound around the drum, and the other end of the hoisting rope is connected to the suspended basket.

[0009] In some embodiments, there are two suspension ropes, which are arranged at intervals along the length of the support beam.

[0021] 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.

[0022] like Figures 1 to 4 As shown, the floating offshore photovoltaic power generation platform 100 of this embodiment includes a top frame 1, a bottom frame 2, a support beam 5, a moving component 6, a lifting component 7, and a basket 8. The top frame 1 and the bottom frame 2 are arranged at intervals in the vertical direction. The top frame 1 is used to install photovoltaic panels 3, and a central column 4 is provided between the center of the top frame and the bottom frame 2. The support beam 5 is located between the top frame 1 and the bottom frame 2 and is arranged parallel to the top frame 1. The support beam 5 includes a first end 501 and a second end 502, which are opposite each other. The first end 501 is rotatably connected to the top of the central column 4, and the second end 502 extends to the edge of the top frame 1. The moving component 6 is movably connected to the support beam 5 along the length direction of the support beam 5. The lifting component 7 is provided on the moving component 6 and connected to the basket 8 for raising and lowering the basket 8.

[0023] The floating offshore photovoltaic power generation platform 100 of this embodiment is used to replace the photovoltaic panels 3 below the top frame 1. When the photovoltaic panels 3 laid on the top frame 1 need to be replaced, the support beam 5 is first rotated to a position below the photovoltaic panel 3 to be replaced. When the support beam 5 reaches a preset position, the rotation of the support beam 5 is stopped. Then, the lifting assembly 7 drives the basket 8 to descend so that the workers can sit in the basket 8. After that, the lifting assembly 7 lifts the basket 8 to a suitable height. Finally, the moving assembly 6 moves the lifting assembly 7 along the length of the support beam 5 so that the basket 8 corresponds vertically to the position of the photovoltaic panel 3 to be replaced, thereby quickly completing the replacement of the photovoltaic panel 3.

[0024] The floating offshore photovoltaic power generation platform 100 of this invention, through the cooperation of the support beam 5, the moving component 6 and the lifting component 7, can quickly locate the position of the photovoltaic panel 3 that needs to be replaced, which facilitates the replacement of the photovoltaic panel 3 and greatly improves the replacement efficiency of the photovoltaic panel 3.

[0025] In some embodiments, a first motor 9 is provided on the support beam 5, a first gear 10 is provided on the output shaft of the first motor 9, and a second gear 11 is mounted on the central column 4, with the first gear 10 meshing with the second gear 11.

[0026] like Figure 3 and Figure 4 As shown, when the first motor 9 starts, it drives the first gear 10 to rotate through its output shaft. The first gear 10 meshes with the second gear 11, and when the first gear 10 rotates, it transmits power to the second gear 11 through meshing. Since the second gear 11 is fixedly mounted on the column, as the first gear 10 rotates, the first gear 10 drives the support beam 5 to rotate, so that the support beam 5 rotates to the appropriate position.

[0027] The gear transmission system has high transmission accuracy, which helps the support beam 5 to rotate accurately on the central column 4, improving the reliability of the system. The gear system is relatively simple, and maintenance and replacement of gear components are generally easy. In this embodiment of the floating offshore photovoltaic power generation platform 100, by adding a first gear 10 and a second gear 11, the rotation system of the support beam 5 becomes more efficient and reliable.

[0028] In some embodiments, the moving component 6 includes a slider 601 and a driving component. The slider 601 is slidably connected to the support beam 5 along the length direction of the support beam 5. The driving component is connected to the slider 601 for driving the slider 601 to slide. The slider 601 is connected to the lifting component 7.

[0029] like Figure 3 and Figure 4 As shown, the slider 601 slides along the length of the support beam 5, ensuring smoother and more precise movement, reducing vibration and errors during motion, and thus improving the overall system's motion accuracy. The drive assembly is connected to the slider 601, enabling more direct and efficient power transmission, allowing the slider 601 to respond quickly and accurately to drive commands, improving drive efficiency. The slider 601's ability to slide freely along the support beam 5 provides greater flexibility and scalability to the system. Its position can be adjusted as needed to adapt to different operational requirements. This design also effectively saves space, making the entire system more compact and easier to install and maintain. During operation, the stable connection between the slider 601 and the support beam 5, along with the precise control of the drive assembly, helps ensure system safety and reduces the risk of accidents.

[0030] In some embodiments, the support beam 5 has a first support plate 12 and a second support plate 13 at both ends. The slider 601 has a threaded through hole extending along the length of the support beam 5. The driving assembly includes a second motor 602 and a screw 603. The screw 603 passes through the threaded through hole and is rotatably connected to the first support plate 12 and the second support plate 13 at both ends. The screw 603 is threadedly engaged with the threaded through hole. The second motor 602 is used to drive the screw 603 to rotate.

[0031] The first support plate 12 and the second support plate 13 provide additional support points for the support beam 5, increasing the overall stability of the system and helping to reduce vibration and offset during movement. Due to the threaded engagement of the screw 603 with the threaded through-hole, the drive motor can precisely control the rotation of the screw 603, thereby achieving precise position control of the slider 601. This mechanical transmission method has high positioning accuracy. The design of the screw 603 and the threaded through-hole allows for direct conversion from rotary motion to linear motion, which is highly efficient and reduces energy loss. The engagement of the threaded through-hole on the slider 601 with the screw 603 allows it to withstand large loads. Due to the threaded engagement, when the second motor 602 stops supplying power, the self-locking characteristic of the screw 603 in the threaded through-hole prevents the slider 601 from moving in the opposite direction due to gravity or external forces, improving system safety.

[0032] In some embodiments, the lifting assembly 7 includes a third motor 701, a drum 702, and a suspension rope 703. The drum 702 is rotatably mounted on the slider 601, the third motor 701 drives the drum 702 to rotate, one end of the suspension rope 703 is wound around the drum 702, and the other end of the suspension rope 703 is connected to the suspended basket 8.

[0033] like Figure 3 and Figure 4 As shown, the precise control capability of the third motor 701 ensures the accurate rotation of the drum 702, thereby enabling precise control of the lifting position of the suspended platform 8. By adjusting the length of the hoisting rope 703, the suspended platform 8 can operate at different heights, thus expanding the application range of the system. The automated lifting mechanism reduces the complexity of manual operation and improves work efficiency, especially in situations requiring frequent lifting operations. Through motor control, the movement status of the suspended platform 8 can be monitored in real time, responding promptly to various situations and reducing safety risks. The introduction of the automated lifting assembly 7 reduces the workload of operators and lowers labor costs. The drum 702 is designed on the slider 601, making the entire lifting assembly 7 compact and space-saving. The cooperation between the drum 702 and the hoisting rope 703 generally has high reliability and can maintain stable performance during long-term use. The lifting assembly 7 can be adjusted according to different application requirements, such as changing the length of the hoisting rope 703 or the diameter of the drum 702, to adapt to different lifting speeds and load requirements.

[0034] Optionally, there are two suspension ropes 703, which are arranged at intervals along the length of the support beam 5.

[0035] The two lifting ropes 703 can share the weight of the suspended platform 8, making the load more evenly distributed on the two ropes 703, reducing the burden on a single rope 703, and improving the load-bearing capacity and stability of the entire system. The design of two lifting ropes 703 can serve as a redundancy mechanism; even if one rope 703 malfunctions, the other rope 703 can still bear the weight of the suspended platform 8, reducing the risk of accidents. Because the lifting ropes 703 are spaced apart on the support beam 5, the swaying of the suspended platform 8 during lifting can be effectively reduced, providing more stable lifting motion. The synchronous movement of the two lifting ropes 703 helps improve the positioning accuracy of the suspended platform 8, especially in situations requiring precise vertical movement. The spaced arrangement of the lifting ropes 703 increases the symmetry of the structure, contributing to the dynamic balance of the entire system during movement. The design of two lifting ropes 703 facilitates individual inspection and maintenance without affecting the normal operation of the other rope 703. This design allows for adjustment of the position and spacing of the lifting ropes 703 as needed to adapt to different sizes of the suspended platform 8 and load requirements. Because there are two suspension ropes 703, the system will not completely fail due to a problem with a single suspension rope 703, improving the system's reliability and continuous operation capability. For workers operating in the suspended platform 8, reduced swaying and increased stability provide a safer and more comfortable working environment.

[0036] In some embodiments, the spool 702 is disposed above the slider 601, and the slider 601 has a first through hole 6011 and a second through hole 6012 extending in a vertical direction, the first through hole 6011 and the second through hole 6012 being used for two suspension ropes 703 to pass through.

[0037] The drum 702, located above the slider 601, helps reduce horizontal space occupation, making the overall structure more compact and suitable for applications with limited space. Since the drum 702 is directly at the starting point of the suspension rope 703, this reduces bending and friction of the rope, improving lifting efficiency. The first perforation 6011 and the second perforation 6012 provide a clear guide path for the suspension rope 703, facilitating its smooth movement and reducing interference and wear during operation. The two suspension ropes 703, passing through different perforations, can independently adjust their tension, ensuring the basket 8 is horizontal or tilted at the desired angle, improving motion control precision. The perforation design on the slider 601 typically increases the local strength of the slider 601, improving its stability under the tension of the suspension rope 703. The independent perforation design makes the installation and replacement of the suspension rope 703 easier, reducing maintenance difficulty.

[0038] In some embodiments, the floating offshore photovoltaic power generation platform 100 of the present invention further includes a support rod 14, one end of which is connected to the second end 502 of the support beam 5, and the other end of which is rotatably connected to the central column 4.

[0039] Support rod 14 provides additional support points, helping to enhance the stability of the entire platform, especially in the face of external environmental factors such as waves and wind. Support rod 14 is rotatably connected to the central column 4, allowing the platform to better adapt to wave motion and reduce structural damage caused by wave impact. By distributing the load on the support beam 5 to support rod 14, the structural burden on the support beam 5 can be reduced, extending its service life. The design of support rod 14 helps improve the overall wind resistance of the platform and reduces the impact of wind loads on the platform. The structural design of support rod 14 typically considers ease of installation and maintenance, making related operations easier. The introduction of support rod 14 can provide more installation space for photovoltaic panels 3, thereby increasing the power generation capacity of the photovoltaic power generation platform. In extreme weather conditions, such as typhoons or large waves, the design of support rod 14 helps the platform maintain buoyancy and stability, improving its survivability in harsh sea conditions.

[0040] Optionally, the angle between the support rod 14 and the support beam 5 is 15°-45°.

[0041] An angle range of 15°-45° typically provides better mechanical properties, enabling the support rod 14 to more effectively transfer and distribute loads when subjected to external forces (such as waves and wind), thereby protecting the entire structure. The direction and intensity of waves and wind may vary under different sea conditions. By adjusting the angle between the support rod 14 and the support beam 5, these variations can be better adapted to, providing more stable and secure support. An appropriate angle increases the stability of the support rod 14, preventing structural instability caused by excessively large or small angles. Within the 15°-45° range, the stress distribution at the connection between the support rod 14 and the support beam 5 is more uniform, helping to reduce material damage caused by fatigue. A reasonable angle design allows for a more compact spatial layout of the entire platform, improving space utilization efficiency. A reasonable angle between the support rod 14 and the support beam 5 helps enhance the overall integrity of the structure, enabling it to exhibit better overall performance when facing external environmental challenges.

[0042] In some embodiments, the floating offshore photovoltaic power generation platform 100 of the present invention further includes a plurality of side columns 15, which are disposed between the top frame 1 and the bottom frame 2, and the plurality of side columns 15 are arranged at intervals along the circumference of the central column 4.

[0043] The addition of side columns 15 provides additional support points for the platform, enhancing its overall stability and resistance to wind and waves. The even distribution of multiple side columns 15 disperses the load borne by the central column 4, reducing the burden on individual columns and extending the structure's service life. The design of the side columns 15 adapts to different seabed conditions and wave heights; by adjusting the height and number of columns, it can accommodate various working environments. The connection between the side columns 15, the central column 4, and the top and bottom frames 2 helps improve the overall structural integrity of the platform, making it a robust and stable whole. The presence of the side columns 15 helps reduce the impact of wind loads on the platform, increasing its wind resistance. The circumferential spacing of the side columns 15 provides a larger installation area for the photovoltaic panels 3, optimizing the overall spatial layout of the platform. In harsh marine environments, the side columns 15 increase the platform's safety, reducing damage caused by wave impacts or wind forces. Under extreme weather conditions, the support of the side columns 15 helps maintain the platform's buoyancy and stability, improving its survivability in harsh sea conditions.
