There are two traveling assemblies, which are positioned opposite each other on the circular track along its center and are capable of traveling along the extension direction of the circular track. The two ends of the support beam are respectively connected to the two traveling assemblies. The moving assembly is movably mounted on the support beam along its length. The telescopic component includes a fixed part and a telescopic part. The fixed part is connected to the moving assembly, and the telescopic part is retractable relative to the fixed part in the vertical direction. The mounting frame is connected to the telescopic part, and a suction cup is provided on the end face of the mounting frame facing away from the telescopic component in the vertical direction.

The annular groove is arranged around the first roller axially. The annular groove is engaged with the circular track and can roll along the extension direction of the circular track. The first motor is drivenly connected to the first rotating shaft to drive the first rotating shaft to rotate. Both ends of the support beam are connected to the walking frame.

[0007] In some embodiments, the walking assembly further includes a first gear and a second gear, the first gear being mounted on the output shaft of the first motor, and the second gear being mounted on the first rotating shaft and meshing with the first gear.

[0008] In some embodiments, the floating offshore photovoltaic power generation platform for easy replacement of photovoltaic panels according to the present invention is characterized by further including a lifting assembly, which is disposed between the traveling frame and the support beam, and the lifting assembly is used to drive the support beam to rise and fall.

[0009] In some embodiments, the lifting assembly includes an inner sleeve, an outer sleeve, a first sealing plate, a second sealing plate, a second motor, and a screw. The inner sleeve is vertically mounted on the traveling frame. The first sealing plate is located at the top end of the inner sleeve and has a threaded hole.

[0024] 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.

[0025] like Figures 1 to 7 As shown, the floating offshore photovoltaic power generation platform 100 of this embodiment includes a floating platform 1, photovoltaic panels 2, a circular track 3, a traveling assembly 4, a support beam 5, a moving assembly 6, a telescopic component 7, and a mounting frame 8. The photovoltaic panels 2 are laid on the floating platform 1, and the circular track 3 is located at the edge of the floating platform 1, surrounding the photovoltaic panels 2. There are two traveling assemblies 4, positioned opposite each other along the center of the circular track 3, and each traveling assembly 4 can travel along the extension direction of the circular track 3. Both ends of the support beam 5 are connected to the two traveling assemblies 4, and the moving assembly 6 is movably mounted on the support beam 5 along its length. The telescopic component 7 includes a fixed part and a telescopic part 702. The fixed part is connected to the moving assembly 6, and the telescopic part 702 is retractable relative to the fixed part in the vertical direction. The mounting frame 8 is connected to the telescopic part 702, and a suction cup 9 is provided on one end face of the mounting frame 8 facing away from the telescopic component 7 in the vertical direction. The suction cup 9 is used to adhere the photovoltaic panels 2.

[0026] In use, when the floating offshore photovoltaic power generation platform 100 of this embodiment needs to replace the photovoltaic panel 2, the two traveling components 4 move in the same direction along the circular track 3 to drive the support beam 5 to rotate relative to the center of the circular track 3. When the support beam 5 rotates to above the photovoltaic panel 2 that needs to be replaced, the movement of the two traveling components 4 stops, and the moving component 6 moves the mounting frame 8 along the length of the support beam 5 so that the mounting frame 8 can move above the photovoltaic panel 2 that needs to be replaced. Then, the telescopic part 702 of the telescopic component 7 is extended so that the suction cup 9 on the mounting frame 8 is adsorbed onto the upper surface of the photovoltaic panel 2 that needs to be replaced. The telescopic part 702 of the telescopic component 7 is then retracted to separate the photovoltaic panel 2 from the floating platform 1. Finally, the moving component 6 moves the adsorbed photovoltaic panel 2 to the edge of the floating platform 1, and the suction cup 9 is used to adsorb a qualified photovoltaic panel 2. The moving component 6 then moves the qualified photovoltaic panel 2 to the position of the disassembled photovoltaic panel 2 for installation, thereby completing the replacement of the photovoltaic panel 2.

[0027] The floating offshore photovoltaic power generation platform 100 of this invention, through the cooperation of the walking component 4 and the moving component 6, can quickly locate the photovoltaic panel 2 that needs to be replaced, facilitating the replacement of the photovoltaic panel 2 and greatly improving the replacement efficiency. Traditional photovoltaic panel 2 replacement requires manual climbing and operation; this invention achieves automated replacement through mechanical devices, reducing manpower input, labor intensity, and safety risks. The use of suction cups 9 to adhere the photovoltaic panel 2 avoids dangerous situations such as slippage and collisions that may occur during manual operation.

[0028] In some embodiments, the mounting bracket 8 is also provided with a 3D sensor 10, which is used to scan for defect information of the photovoltaic panel 2.

[0029] The 3D sensor 10 can scan the photovoltaic panel 2, collecting three-dimensional data of its surface. This data allows for the precise detection of defects such as cracks, bends, and dirt buildup in the photovoltaic panel 2. Before replacing the photovoltaic panel 2, the 3D sensor 10 can monitor its condition in real time, assessing the extent of damage and the necessity of replacement. The sensor can also collect key parameters such as the size and shape of the photovoltaic panel 2, providing accurate data support for the replacement operation. Combined with the walking component 4 and the moving component 6, the 3D sensor 10 can help automatically locate defects on the photovoltaic panel 2, improving the accuracy of detection and replacement.

[0030] Compared to traditional manual visual inspection or simple two-dimensional image detection, the 3D sensor 10 can provide more accurate defect information, helping to more accurately assess the condition of the photovoltaic panel 2. Through real-time monitoring of the photovoltaic panel 2, maintenance personnel can make more scientific and reasonable maintenance decisions based on the data provided by the 3D sensor 10, avoiding over-maintenance or delayed maintenance. Through real-time monitoring and automatic defect location, the maintenance team can respond quickly and replace damaged photovoltaic panels 2 in a timely manner, thereby reducing downtime of the power generation platform and improving power generation efficiency. Regular inspection and timely replacement of damaged photovoltaic panels 2 can effectively extend the overall service life of the photovoltaic power generation platform.

[0031] In some embodiments, the walking assembly 4 includes a walking frame 401, a first roller 402, a first rotating shaft 403, and a first motor 404. The first roller 402 is rotatably connected to the walking frame 401 via the first rotating shaft 403. An annular groove 4021 is formed on the outer circumferential surface of the first roller 402, and the annular groove 4021 is arranged around the first roller 402 axially. The annular groove 4021 is engaged with the circular track 3 and can roll along the extension direction of the circular track 3. The first motor 404 is drively connected to the first rotating shaft 403 to drive the first rotating shaft 403 to rotate. Both ends of the support beam 5 are connected to the walking frame 401.

[0032] like Figure 2 and Figure 6 As shown, the first roller 402 rolls via the rotation of the first shaft 403, thereby propelling the walking component 4 along the circular track 3. The engagement of the annular groove 4021 with the circular track 3 ensures the stability and directional movement of the walking component 4 on the track, preventing lateral slippage. The first motor 404 drives the first shaft 403 through a transmission system, which in turn drives the first roller 402 to rotate, thus realizing the walking motion of the walking component 4. The two ends of the support beam 5 are connected to the walking frame 401, which allows the support beam 5 to remain stable when the walking component 4 moves, and also facilitates the transmission of the moving power of the walking component 4.

[0033] The design of the traveling frame 401 and the tight fit between the rollers and the track ensure the stability of the traveling assembly 4 during movement. The design of the annular slot 4021 allows the traveling assembly 4 to move accurately along the annular track, improving positioning accuracy. The modular design of the traveling assembly 4 makes maintenance and component replacement more convenient and faster. The smooth rolling motion achieved by the motor-driven rollers improves movement efficiency and reduces energy consumption. Therefore, the floating offshore photovoltaic power generation platform 100 of this embodiment is more flexible, efficient, and stable, providing important support for the operation and maintenance of offshore photovoltaic power generation.

[0034] In some embodiments, the walking assembly 4 further includes a first gear 405 and a second gear 406. The first gear 405 is mounted on the output shaft of the first motor 404, and the second gear 406 is mounted on the first rotating shaft 403 and meshes with the first gear 405.

[0035] like Figure 3 and Figure 6 As shown, when the first motor 404 starts, it drives the first gear 405 to rotate via its output shaft. The first gear 405 meshes with the second gear 406, and when the first gear 405 rotates, it transmits power to the second gear 406 through this meshing. The second gear 406 is mounted on the first shaft 403. As the second gear 406 rotates, the first shaft 403 also rotates, thereby driving the first roller 402 to rotate. The first roller 402 rolls due to the rotation of the first shaft 403, propelling the walking assembly 4 along the circular track 3.

[0036] The gear transmission system has high transmission accuracy, which helps the walking component 4 move accurately on the track. The gear transmission system has good enclosure, which can reduce the impact of the external environment on the walking component 4 and improve the system's reliability. 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 405 and a second gear 406, the power transmission system of the walking component 4 becomes more efficient and reliable.

[0037] In some embodiments, the floating offshore photovoltaic power generation platform 100 of the present invention further includes a lifting assembly 11, which is disposed between the traveling frame 401 and the support beam 5, and is used to drive the support beam 5 to rise and fall.

[0038] Specifically, during operation, maintenance personnel can use the lifting assembly 11 to ride on the mounting frame 8, and then move the mounting frame 8 to the location where the photovoltaic panel 2 needs to be replaced, and then replace the photovoltaic panel 2. Thus, through mechanized lifting operations, the risks of direct climbing and manual operation for maintenance personnel can be reduced, improving work safety. The introduction of the lifting assembly 11 can reduce the time required to replace the photovoltaic panel 2, further improving maintenance efficiency. The lifting assembly 11 allows the support beam 5 to adapt to different heights, increasing the platform's adaptability.

[0039] In some embodiments, the lifting assembly 11 includes an inner sleeve 1101, an outer sleeve 1102, a first sealing plate 1103, a second sealing plate 1104, a second motor 1105, and a screw 1106. The inner sleeve 1101 is vertically mounted on the traveling frame 401. The first sealing plate 1103 is located at the top end of the inner sleeve 1101 and has a threaded hole. The outer sleeve 1102 is fitted onto the inner sleeve 1101 and is vertically slidably engaged with it. The second sealing plate 1104 is located at the top end of the outer sleeve 1102 and has a through hole. The screw 1106 passes through the through hole and is threadedly connected to the threaded hole. The second motor 1105 is mounted on the second sealing plate 1104 and connected to the screw 1106. The support beam 5 is connected to the outer sleeve 1102.

[0040] Specifically, when the lifting assembly 11 is in operation, the second motor 1105 starts, driving the screw 1106 to rotate. Since the screw 1106 is connected to the threaded hole on the first sealing plate 1103, the rotation of the screw 1106 is converted into lifting motion, causing the outer sleeve 1102 to rise and fall vertically. This, in turn, causes the outer sleeve 1102 to lift and fall the support beam 5. The cooperation between the inner sleeve 1101 and the outer sleeve 1102 provides guidance and support, ensuring the linearity of the lifting action and preventing lateral movement. The first sealing plate 1103 and the second sealing plate 1104 are located at the top of the inner sleeve 1101 and the outer sleeve 1102, respectively. They seal and fix the lifting assembly 11, preventing leakage of lubricating oil or other media and maintaining the stability of the lifting mechanism. By controlling the start, stop, and speed of the second motor 1105, the lifting speed and position of the support beam 5 can be precisely controlled, achieving fine lifting control. Through the drive of the second motor 1105 and the threaded connection, the lifting assembly 11 can provide precise lifting control. The design of the inner sleeve 1101 and the outer sleeve 1102 provides stable guidance and support, ensuring the stability of the platform during lifting.

[0041] In some embodiments, a groove 501 extending along the length direction is formed on the top surface of the support beam 5. The moving assembly 6 includes a moving frame 601, a second roller 602, a second rotating shaft 603, and a third motor 604. The second roller 602 is rotatably connected to the moving frame 601 via the second rotating shaft 603. A portion of the second roller 602 is located within the groove 501, and the outer wall of the second roller 602 abuts against the bottom wall of the groove 501. The third motor 604 is drive-connected to the second rotating shaft 603. The moving frame 601 is connected to the fixed part of the telescopic rod.

[0042] Specifically, when the third motor 604 starts, it drives the second roller 602 to rotate. Since part of the second roller 602 is located within the groove 501, the rotation of the second roller 602 causes the moving component 6 to move along the length of the support beam 5. The outer wall of the second roller 602 contacts the bottom wall of the groove 501. This contact ensures the stability and straightness of the moving component 6 on the support beam 5.

[0043] The engagement of the groove 501 and the second roller 602 increases stability during movement and reduces lateral movement and vibration. The rolling motion of the second roller 602 significantly reduces friction compared to sliding friction, improving movement efficiency. The design of the moving component 6 facilitates maintenance and replacement, reducing operating costs. The moving component 6 makes operations on the support beam 5 more flexible, allowing for rapid response to the replacement and maintenance needs of the photovoltaic panel 2.

[0044] In some embodiments, the moving component 6 further includes a third gear 605 and a fourth gear 606, the third gear 605 being mounted on the output shaft of the third motor 604, and the fourth gear 606 being mounted on the second rotating shaft 603 and meshing with the third gear 605.

[0045] Specifically, such as Figure 4 and Figure 7 As shown, when the third motor 604 starts, it drives the third gear 605 to rotate via its output shaft. The third gear 605 meshes with the fourth gear 606, and the rotation of the third gear 605 is transmitted to the fourth gear 606 through this meshing. The fourth gear 606 is mounted on the second shaft 603. As the fourth gear 606 rotates, the second shaft 603 also rotates, thereby driving the second roller 602 to rotate. The second roller 602 rolls due to the rotation of the second shaft 603, pushing the moving assembly 6 along the groove 501 of the support beam 5.

[0046] Compared to direct motor drive of the shaft, gear transmission systems reduce friction and improve transmission efficiency. The gear meshing transmission method offers high transmission accuracy, facilitating the precise movement of the moving component 6 within the groove 501 of the support beam 5. The use of a gear transmission system not only improves the motion accuracy of the moving component 6 but also increases the stability and durability of the entire system.

[0047] In some embodiments, there are multiple second rotating shafts 603 and multiple second rollers 602, which are matched one-to-one, and the multiple second rollers 602 are arranged at intervals along the length of the support beam 5.

[0048] As the moving component 6 moves on the support beam 5, the evenly distributed multiple second rollers 602 help to distribute the weight and reduce the burden on individual rollers. The rolling motion of the second rollers 602 within the grooves 501 of the support beam 5, due to the increased number of second rollers 602, provides better guidance and stability. The third motor 604, through the meshing of the third gear 605 and the fourth gear 606, transmits power to each second shaft 603, thereby driving the corresponding second roller 602 to rotate. The even distribution of multiple second rollers 602 helps improve the stability of the moving component 6 on the support beam 5, reducing swaying and vibration during movement. The weight distribution of multiple second rollers 602 increases the load-bearing capacity of the moving component 6, enabling it to handle heavier photovoltaic panels 2 or other equipment. Because the load is distributed across multiple second rollers 602, wear on individual rollers is reduced, thus extending the service life of the second rollers 602 and the second shaft 603. The even arrangement of multiple second rollers 602 and the high efficiency of the gear transmission system allow the moving component 6 to move faster and more smoothly.

[0049] In some embodiments, there are multiple suction cups 9, which are arranged in a matrix on the mounting bracket 8.

[0050] The suction cups 9 generate suction through vacuum or other means to firmly adhere to the photovoltaic panel 2, ensuring that the photovoltaic panel 2 will not move or fall off during replacement. The matrix arrangement of the suction cups 9 can be adjusted according to the size and shape of the photovoltaic panel 2 to accommodate different specifications. Multiple suction cups 9 can work simultaneously, improving the efficiency of adhering to the photovoltaic panel 2 and reducing replacement time. The matrix arrangement of the suction cups 9 allows for selection of different positions for operation as needed, increasing the flexibility of photovoltaic panel 2 replacement. This design can adapt to photovoltaic panels 2 of different sizes and shapes, improving the versatility and adaptability of the equipment. The simultaneous adsorption of the photovoltaic panel 2 by multiple suction cups 9 provides greater stability, ensuring that the photovoltaic panel 2 will not shift due to insufficient suction at a single point during replacement.
