[0018] Please refer to Figure 1~Figure 3 As shown, a fish-photovoltaic complementary photovoltaic operation and maintenance ship transport device is used to transport the objects that need to be transferred from the pond 2 to the operation and maintenance ship, including: The lifting platform 3 is installed in the ship hold 1 of the operation and maintenance ship; A first lifting device 4, used to lift the lifting platform 3 in the vertical direction; A first sliding frame 5 is slidably connected to the lifting platform 3, and two rows of first rollers 6 arranged in parallel for transporting objects to be transferred are installed on the first sliding frame 5. A locking column 7 parallel to the movement direction of the first sliding frame 5 is fixedly connected to the first sliding frame 5, and the locking column 7 is located below the first roller 6; A first telescopic device 8 is installed between the lifting platform 3 and the first sliding frame 5, and is used to push the first sliding frame 5 to slide on the lifting platform 3; A mounting frame 9 is arranged on the pond bank 2, and a locking cylinder 10 is hinged on the mounting frame 9, and the locking cylinder 10 cooperates with the locking column 7; A second sliding frame 11 is hinged on the mounting frame 9, and two rows of second rollers 12 arranged in parallel are mounted on the second sliding frame 11 for transporting objects to be transferred; The locking device 13 is mounted on the mounting frame 9 and is used to lock the locking column 7 that cooperates with the locking cylinder 10 .

[0019] Working principle: The height of the first sliding frame 5 is adjusted in the vertical direction through the lifting platform 3 and the first lifting device 4, so that the locking column 7 is flush with the locking cylinder 10, and the first telescopic device 8 is used to push the first sliding frame 5 to slide along the lifting platform 3, and the locking column 7 is used to cooperate with the locking cylinder 10 on the mounting frame 9 of the embankment 2 to lock the inverter from the embankment 2 to the operation and maintenance ship. Smooth and safe transportation.

[0020] The first telescopic device 8, the second telescopic device 132, the first lifting device 4 and the second lifting device 17 may all be hydraulic cylinders.

[0021] In this embodiment, please refer to Figure 3 As shown, the mounting frame 9 is arranged in a V shape, the locking cylinder 10 is located in the middle of the V shape of the mounting frame 9, the locking device 13 comprises a cylinder 131 which is fixedly connected to the two arms of the mounting frame 9 and is interconnected, a second telescopic device 132 and a positioning pin 133 are arranged in the cylinder 131, the second telescopic device pushes the positioning pin 133 to move relative to each other, and a locking hole 71 which matches the positioning pin 133 is opened at the end of the locking column 7. The positioning pin 133 is pushed into the locking hole 71 at the end of the locking column 7 by the second telescopic device 132, providing a more secure and reliable mechanical locking.

[0022] In this embodiment, please refer to Figure 3 As shown, two connecting shafts 101 are fixedly connected to the locking cylinder 10, and the connecting shafts 101 are rotatably connected to the two arms of the mounting frame 9. The locking cylinder 10 and the connecting shafts 101 are provided with connecting holes 102 that communicate with the two cylinders 131. The rotatable connection design of the locking cylinder 10 and the connecting shafts 101 ensures the precise alignment of the locking cylinder 10 and the locking column 7, and enhances the stability and reliability of the locking. It also ensures that the positioning pin 133 locks the locking column 7.

[0023] In this embodiment, please refer to Figure 3 As shown, the second sliding frame 11 is fixedly connected with a tripod 111, and the tripod 111 includes a short frame and a long frame. The intersection of the short frame and the long frame is hinged on the mounting frame 9, the short frame is located on the side close to the water surface, and the long axis is located on the side away from the water surface. The long frame makes the center of gravity of the second sliding frame 11 located on the side away from the water surface, which is convenient for starting to transfer the inverter to the second sliding frame 11. During the movement of the inverter on the second sliding frame 11, the second sliding frame 11 tilts toward the first sliding frame 5 and overlaps the first sliding frame 5. The overlapping method can make the second sliding frame 11 and the first sliding frame 5 produce some relative movement under the action of waves but not separate, thereby reducing the influence of the up and down shaking of the hull on the transfer of the inverter, ensuring the safe transportation of the inverter.

[0024] In this embodiment, please refer to Figure 1 As shown, the end of the second sliding frame 11 close to the water surface is fixedly connected with a transversely arranged frame 112, and the frame 112 is used to be mounted on the first sliding frame 5. The width of the second sliding frame 11 is greater than or less than the width of the second sliding frame 11, so that the second roller 12 is staggered with the first roller 6. The frame 112 is used to be mounted between the adjacent first rollers 6 of the first sliding frame 5, which facilitates the connection between the first sliding frame 5 and the second sliding frame 11. The width avoids the interference between the first roller 6 and the second roller 12, and improves the stability of the inverter transfer.

[0025] In this embodiment, please refer to Figure 2 As shown, the first sliding frame 5 includes a guide rail 51 and a V-shaped connecting rod 52. The guide rail 51 is slidably connected to the lifting platform 3. The bottom end of the connecting rod 52 is fixedly connected to the locking column 7. The connecting rod 52 is located at both ends of the guide rail 51. The combined structure of the guide rail 51 and the V-shaped connecting rod 52 ensures the smooth sliding of the first sliding frame 5 on the lifting platform 3 and firmly connects the locking column 7. Space is also reserved for the partition 15 to avoid interference with the partition 15, thereby improving the safety of the ship cabin 1.

[0026] In this embodiment, please refer to Figure 2 As shown, one end of the first telescopic device 8 is hinged on the guide rail 51, and the other end is hinged on the lifting platform 3 and is located at the bottom of the guide rail 51. This realizes the precise pushing of the first sliding frame 5, improves the flexibility and accuracy of the operation, and avoids the interference between the lifting platform 3 and the partition 15 when lifting.

[0027] In this embodiment, please refer to Figure 2 As shown, a trough 14 for accommodating a guide rail 51 is provided in the hold 1 of the maintenance ship, a partition 15 is provided in the middle of the guide rail 51, and the partition 15 is connected to a U-shaped support rod 16, and the U-shaped support rod 16 is fixed inside the hull to support the partition 15. The trough 14 provided in the hold 1 and the U-shaped support rod 16 supporting the partition 15 are designed to prevent the lifting platform 3 from interfering with the partition 15 when lifting.

[0028] In this embodiment, please refer to Figure 3 As shown, the bottom of the mounting frame 9 adopts a telescopic cylinder, the top of which is fixedly connected to a fixing plate, and the fixing plate is connected to a second lifting device 17 for lifting the mounting frame 9. The telescopic cylinder and the second lifting device 17 at the bottom of the mounting frame 9 enable the mounting frame 9 to be adjusted in height according to the change of the water level, ensuring the adaptability and ease of operation of the entire handling system.

[0029] The end of the first sliding frame 5 close to the pond bank is set to be an arc slanted downward, so that the second sliding frame 11 overlaps it. This allows the first sliding frame 5 to overcome the height difference with the second sliding frame 11 after the lifting platform 3 is fixed at a certain height, facilitating smooth transfer of items.

[0030] The present invention also provides a method for transporting a fishery-photovoltaic complementary photovoltaic operation and maintenance vessel, using the above-mentioned transport device, comprising the following steps: S1, fix the mounting frame 9 at a proper position of the pond bank 2, and transfer the object to be transferred to the end of the second sliding frame 11 away from the water surface; S2, start the first lifting device 4, accurately adjust the height of the locking column 7 of the first sliding frame 5 according to the change of the current water level, until the locking column 7 is completely aligned with the locking cylinder 10 installed on the pond bank 2, after the locking column 7 is aligned with the locking cylinder 10, use the first telescopic device 8 to push the first sliding frame 5 to move toward the locking cylinder 10, so that the locking column 7 and the locking cylinder 10 are matched, and then use the locking device 13 to mechanically lock the two; S3, push the object to be transferred to move on the second sliding frame 11, after the object to be transferred passes the hinge point of the second sliding frame 11, overlap the end of the second sliding frame 11 close to the water surface on the first sliding frame 5, continue to move the object to be transferred to the first sliding frame 5, the second sliding frame 11 recovers and separates from the first sliding frame 5 with the assistance of itself or the operator; S4. After the object to be transferred is transferred to the appropriate position on the first sliding frame 5, the locking device 13 is released to withdraw the locking column 7 from the locking cylinder 10, and the first telescopic device 8 is used to retract the first sliding frame 5. Then the first lifting device 4 is started to lower the entire lifting platform 3 together with the first sliding frame 5 and the object to be transferred until the object to be transferred is placed in the hold 1, thereby completing the transfer of the object to be transferred.

[0031] This method ensures the stability and safety of the inverter during transportation by precisely controlling the alignment and locking of the locking column 7 and the locking cylinder 10 under water level changes, while improving transportation efficiency and reducing manual intervention. It is suitable for inverters of different sizes and weights.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
