[0021] 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.

[0022] like Figures 1 to 4 As shown, the floating offshore photovoltaic power generation platform 100 of the embodiment of the present invention includes a top frame 1, a bottom frame 2, a support beam 5, a moving assembly 6, a lifting assembly 7 and a hanging 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 the photovoltaic panel 3, and a central column 4 is provided between the central part of the top frame and the bottom frame 2. The support beam 5 is arranged 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 opposite to 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 assembly 6 is movably connected to the support beam 5 along the length direction of the support beam 5, and the lifting assembly 7 is arranged on the moving assembly 6 and connected to the hanging basket 8, and is used to lift the hanging basket 8.

[0023] The floating offshore photovoltaic power generation platform 100 of the embodiment of the present invention is used to replace the yellow sub-shift 3 below the top frame 1 when in use. When the photovoltaic panel 3 laid on the top frame 1 needs to be replaced, the support beam 5 is first rotated to rotate the support beam 5 to below the position of the photovoltaic panel 3 that needs to be replaced on the top frame 1. When the support beam 5 rotates to the preset position, the rotation of the support beam 5 is stopped. Then the hanging basket 8 is driven to descend by the lifting assembly 7 so that the staff can sit in the hanging basket 8, and then the hanging basket 8 is driven to rise to a suitable height by the lifting assembly 7, and finally the lifting assembly 7 is driven by the moving assembly 6 to move in the length direction of the support beam 5, so that the hanging basket 8 corresponds to the position of the photovoltaic panel 3 that needs to be replaced in the vertical direction, thereby quickly completing the replacement of the photovoltaic panel 3.

[0024] The floating offshore photovoltaic power generation platform 100 of the embodiment of the present invention can quickly locate the position of the photovoltaic panel 3 that needs to be replaced through the cooperation of the support beam 5, the moving component 6 and the lifting component 7, 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 disposed on the support beam 5 , a first gear 10 is disposed on the output shaft of the first motor 9 , a second gear 11 is mounted on the center column 4 , and the first gear 10 is meshed with the second gear 11 .

[0026] like Figure 3 and Figure 4 As shown, when the first motor 9 is started, it drives the first gear 10 to rotate through its output shaft. The first gear 10 is meshed with the second gear 11. When the first gear 10 rotates, it transmits power to the second gear 11 through meshing. Since the second gear 11 is fixedly sleeved 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 a suitable position.

[0027] The gear transmission system has high transmission accuracy, which helps the support beam 5 to rotate accurately on the central column 4, thereby improving the reliability of the system. The gear system is relatively simple, and it is usually easier to maintain and replace the gear components. The floating offshore photovoltaic power generation platform 100 of the embodiment of the present invention adds the first gear 10 and the second gear 11, so that 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 slider 601 is transmission-connected to drive 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 direction of the support beam 5, which can ensure that the movement of the slider 601 is more stable and accurate, and helps to reduce vibration and errors during the movement, thereby improving the movement accuracy of the entire system. The drive assembly is connected to the slider 601 in a transmission manner, which can transmit power more directly and efficiently, so that the slider 601 can respond to the drive command quickly and accurately, and improve the drive efficiency. Since the slider 601 can slide freely along the support beam 5, the system is provided with greater flexibility and scalability. The position of the slider 601 can be adjusted as needed to adapt to different work requirements. Since the slider 601 can slide along the support beam 5, this design can effectively save space, making the entire system more compact and easy to install and maintain. During the movement process, the stable connection between the slider 601 and the support beam 5 and the precise control of the drive assembly help to ensure the safety of the system and reduce the risk of accidents.

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

[0031] The first support plate 12 and the second support plate 13 provide additional support points for the support beam 5, increase the overall stability of the system, and help reduce vibration and offset during movement. Due to the threaded cooperation between the screw 603 and the threaded through hole, the drive motor can accurately control the rotation of the screw 603, thereby realizing the precise position control of the slider 601. This mechanical transmission method has a high positioning accuracy. The design of the screw 603 and the threaded through hole can realize the direct conversion from rotational motion to linear motion. This conversion efficiency is high and reduces energy loss. The threaded through hole on the slider 601 cooperates with the screw 603 to bear a large load. Due to the cooperation of the thread, when the second motor 602 stops supplying power, the self-locking characteristics of the screw 603 in the threaded through hole can prevent the slider 601 from moving in the opposite direction due to gravity or external forces, thereby improving the safety of the system.

[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 disposed on the slider 601, the third motor 701 is used to drive 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 hanging basket 8.

[0033] like Figure 3 and Figure 4 As shown, the precise control capability of the third motor 701 ensures the precise rotation of the drum 702, so that the lifting position of the hanging basket 8 can be precisely controlled. By adjusting the length of the suspension rope 703, the hanging basket 8 can achieve work at different heights, thereby expanding the application range of the system. The automated lifting mechanism reduces the complexity of manual operation and improves work efficiency, especially in occasions where frequent lifting operations are required. Through the control of the motor, the movement state of the hanging basket 8 can be monitored in real time, and various situations can be responded to in a timely manner to reduce safety risks. The introduction of the automated lifting assembly 7 reduces the workload of the operator and reduces labor costs. The drum 702 is designed on the slider 601, so that the entire lifting assembly 7 is compact and space-saving. The cooperation of the drum 702 and the suspension rope 703 usually 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 suspension 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 , and the two suspension ropes 703 are arranged at intervals in the length direction of the support beam 5 .

[0035] The two suspension ropes 703 can share the weight of the hanging basket 8, so that the load is more evenly distributed on the two suspension ropes 703, reducing the burden of a single suspension rope 703, and improving the carrying capacity and stability of the entire system. The design of the two suspension ropes 703 can be used as a redundant mechanism. Even if one of the suspension ropes 703 has a problem, the other suspension rope 703 can still bear the weight of the hanging basket 8, reducing the risk of accidents. Since the suspension ropes 703 are arranged at intervals on the support beam 5, the swing of the hanging basket 8 during the lifting process can be effectively reduced, providing a more stable lifting movement. The synchronous movement of the two suspension ropes 703 helps to improve the positioning accuracy of the hanging basket 8, especially in situations where precise vertical movement is required. The interval arrangement of the suspension ropes 703 increases the symmetry of the structure and helps the dynamic balance of the entire system during the movement. The design of the two suspension ropes 703 is convenient for separate inspection and maintenance, and will not affect the normal operation of the other suspension rope 703. This design can adjust the position and interval of the suspension ropes 703 as needed to adapt to different sizes and load requirements of the hanging basket 8. Due to the presence of two suspension ropes 703, the system will not fail completely due to a problem with a single suspension rope 703, thereby improving the reliability and continuous working capability of the system. For the staff who need to operate in the hanging basket 8, reducing swing and improving stability can provide a safer and more comfortable working environment.

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

[0037] The reel 702 is located above the slider 601, which helps to reduce the horizontal occupied space, making the overall structure more compact and suitable for application scenarios with limited space. Since the reel 702 is directly located at the starting point of the suspension rope 703, this can reduce the bending and friction of the suspension rope 703 and improve the lifting efficiency. The first perforation 6011 and the second perforation 6012 provide a clear guide path for the suspension rope 703, which helps the smooth movement of the suspension rope 703 and reduces interference and wear during the movement. The two suspension ropes 703 can independently adjust their respective tensions through different perforations to ensure that the hanging basket 8 is horizontal or tilted at the expected angle, thereby improving the control accuracy of the movement. The perforation design on the slider 601 usually increases the local strength of the slider 601 and improves the stability of the slider 601 under the tension of the suspension rope 703. The independent perforation design makes the installation and replacement of the suspension rope 703 more convenient and reduces the difficulty of maintenance.

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

[0039] The support rod 14 provides an additional support point, which helps to enhance the stability of the entire platform, especially when facing external environmental factors such as waves and wind. The support rod 14 is rotatably connected to the central column 4, so that the platform can better adapt to the movement of waves and reduce structural damage caused by wave impact. By dispersing the load on the support beam 5 to the support rod 14, the structural burden of the support beam 5 can be reduced and its service life can be extended. The design of the support rod 14 helps to improve the overall wind resistance of the platform and reduce the impact of wind load on the platform. The structural design of the support rod 14 usually takes into account the convenience of installation and maintenance, making related operations easier to perform. The introduction of the support rod 14 can provide a larger installation space for the photovoltaic panel 3, thereby increasing the power generation capacity of the photovoltaic power generation platform. Under extreme weather conditions, such as typhoons or big waves, the design of the support rod 14 helps the platform maintain buoyancy and stability, and improves its survivability in harsh sea conditions.

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

[0041] The angle range of 15°-45° can usually provide better mechanical properties, so that the support rod 14 can more effectively transfer and disperse the load when subjected to external forces (such as waves and wind), thereby protecting the entire structure. Under different sea conditions, the direction and intensity of waves and wind may be different. By adjusting the angle between the support rod 14 and the support beam 5, these changes can be better adapted to provide more stable and safe support. The appropriate angle can increase the stability of the support rod 14 and avoid structural instability caused by excessive or small angles. Within the range of 15°-45°, the stress distribution at the connection between the support rod 14 and the support beam 5 is relatively uniform, which helps to reduce material damage caused by fatigue. Reasonable angle design can make the spatial layout of the entire platform more compact and improve space utilization efficiency. The reasonable angle between the support rod 14 and the support beam 5 helps to enhance the integrity of the entire structure, so that it can show better overall performance when facing external environmental challenges.

[0042] In some embodiments, the floating offshore photovoltaic power generation platform 100 of the embodiment 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 the side columns 15 provides an additional support point for the platform, which helps to enhance the stability and wind and wave resistance of the entire platform. Through the uniform distribution of multiple side columns 15, the load borne by the central column 4 can be dispersed to the surroundings, reducing the burden of a single column and extending the service life of the structure. The design of the side columns 15 can adapt to different seabed conditions and wave heights, and can adapt to different working environments by adjusting the height and number of the columns. The connection between the side columns 15 and the central column 4 and the top and bottom frames 2 helps to improve the structural integrity of the entire platform, making it a solid and stable whole. The presence of the side columns 15 helps to reduce the impact of wind loads on the platform and increase the wind resistance of the platform. The circumferential spacing of the side columns 15 can provide a larger installation area for the photovoltaic panels 3 and optimize the spatial layout of the entire platform. In harsh marine environments, the side columns 15 can increase the safety of the platform and reduce damage caused by wave impact or wind. Under extreme weather conditions, the support of the side columns 15 helps to maintain the buoyancy and stability of the platform and improve its survivability in harsh sea conditions.
