In some embodiments, in order to avoid the new energy battery 300 from being tilted or the like during hoisting, the lifting power part 431 is two, and the two lifting power parts 431 are symmetrically arranged at the two ends of the trolley 410. In some embodiments, in order to hoist more stably and reliably, the lifting power part 431 is four, and the four lifting power parts 431 are respectively arranged at the four corners of the trolley 410. In some possible implementation manners, the first pulley 4312 is connected with the trolley 410 through a pulley fixing seat 4315, and the pulley fixing seat 4315 is connected with the trolley 410 through a screw. The second pulley 4313 is also connected with the hoisting body 433 through the pulley fixing seat 4315, and the pulley fixing seat 4315 is welded on the hoisting body 433.
[0048] Specifically, the hoisting body 433 moves up and down relative to the trolley 410 by the winch 4311 driving the steel wire rope 4314 to stretch and retract, which is simple in structure and stable and reliable in operation.
[0049] Further, the grabbing component 440 comprises a plurality of hooks 441 connected to the hoisting body 433 of the hoisting component 430 for interfacing with the new energy battery 300. Specifically, the hoisting body 433 can be interfaced with the new energy battery 300 by hooking the hooks 441 on the frame on the top of the new energy battery 300, which is simple in structure, stable and reliable in connection, and avoids disengagement of the hooks 441 from the new energy battery 300 during hoisting.
[0050] Further, the hooks 441 are rotationally connected to the hoisting body 433 of the hoisting component 430, and the grabbing component 440 further comprises a grabbing power component 442 connected to the hoisting body 433 of the hoisting component 430, with the output end of the grabbing power component 442 connected to the hooks 441 for driving the hooks 441 to rotate. In some embodiments, the grabbing power component 442 is an electric motor, and the output end of the electric motor is connected to the hooks 441. The hooks 441 are rotationally connected to the hoisting body 433 through a bearing.

[0051] Specifically, in order to achieve full automation, the rotation of the hooks 441 is directly controlled by the grabbing power component 442, so that the hooks 441 are retracted below the hoisting body 433 when the hooks 441 are not in contact with the new energy battery 300, thereby smoothly passing through the top of the new energy battery 300; after descending to the target position, the rotation of the hooks 441 is directly controlled by the grabbing power component 442, so that part of the hooks 441 is exposed outside the hoisting body 433, thereby hooking the frame on the top of the new energy battery 300 through the exposed part of the hooks 441, thereby achieving automatic interfacing of the hooks 441 with the new energy battery 300 and reducing labor costs.
[0052] Further, the present application also comprises a guide assembly, which comprises a guide column 600 provided on the hoisting body 433 of the hoisting component 430 and a guide hole provided on the cart 410; the guide column 600 cooperates with the guide hole. Specifically, when the hoisting component 430 moves up and down relative to the cart 410, the cooperation between the guide column 600 and the guide hole in the present embodiment can play a guiding role, making the operation more stable. In order to further improve the guiding effect, the top end of the guide column 600 is conical.
[0053] Further, the lifting component 430 plays a guiding role when it is lowered to contact the new energy battery 300. The embodiment is provided with a plurality of lifting inclined guides 700 at the bottom of the lifting body 433. Thus, the lifting component 430 can be quickly lowered to the inside of the frame on the top of the new energy battery 300 without contact.
[0054] When the new energy battery 300 needs to be replaced, the ship 100 is docked near the shore. After docking, the robot 400 hoists the empty new energy battery 300 in the container 200 to the No. 2 buffer bottom support 500. The other docking equipment (for example, a forklift or a robot 400) on the shore puts the full new energy battery 300 on the No. 1 buffer bottom support 500. Then the docking equipment takes the empty new energy battery 300 on the No. 2 buffer bottom support 500 to the shore. Finally, the robot 400 hoists the full new energy battery 300 into the container 200, and the replacement of the battery is completed.
[0055] Obviously, the above embodiment is only an example for clear illustration, and is not a limitation on the implementation. Based on the above description, other different forms of changes or variations can be made by those skilled in the art. Here, it is not necessary and impossible to enumerate all the implementations. The obvious changes or variations derived therefrom are still within the protection scope of the present application.
