[0034] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0035] The specific structure of a battery-swap ship provided by an embodiment of the present invention and the corresponding technical effects it brings are described in detail below in conjunction with the patent drawings.

[0036] Please refer to Figure 1-Figure 2 as well as Figure 5-Figure 6 , a battery swap ship 1 provided by an embodiment of the present invention includes a lower transfer device 200 of a lower battery 2 storage compartment and an upper deck 300. The lower battery 2 storage compartment has a first transfer position 100 and a lower storage position, the lower storage position is used to store multiple batteries 2, the lower transfer device 200 is installed in the lower battery 2 storage compartment, and the lower transfer device 200 is used to transfer the battery 2 from the lower storage position to the first transfer position 100 or transfer the battery 2 from the first transfer position 100 to the lower storage position. The upper deck 300 is provided with a transfer channel 310 opposite to the first transfer position 100. The upper deck 300 is also provided with an upper transfer device, which includes a mounting frame 360 ​​and a sling 370. The sling 370 is installed on the top of the mounting frame 360. The sling 370 can move in the horizontal direction and the height direction relative to the mounting frame 360. The horizontal direction is perpendicular to the height direction. The sling 370 is used to transfer the battery 2 at the first transfer position 100 to the electric boat 3 or to transfer the battery 2 on the electric boat 3 to the first transfer position 100.

[0037] It should be noted that the transfer channel 310 can be understood as an opening connecting the lower battery 2 storage compartment and the upper deck 300.

[0038] It can be understood that the lower storage position can be used to store batteries 2 for powering the electric boat 3. When the electric boat 3 needs to replace the batteries 2, the battery-exchanging boat 1 can transfer the batteries 2 in the lower storage position to the first transfer position 100 in advance through the lower transfer device 200. The battery-exchanging boat 1 can travel in the sea or river area. It can travel around the electric boat 3 that needs to replace the batteries 2, and then transfer the batteries 2 in the first transfer position 100 to the electric boat 3 through the upper transfer device, so as to facilitate the electric boat 3 to replace the low-power batteries 2 on itself with the batteries 2 transferred to it. It should be noted that the upper transfer device can also transfer the low-power batteries 2 on the electric boat 3 to the first transfer position 100, and put them into the replacement battery 2 position through the lower transfer device 200.

[0039] It can be understood that the battery-exchange ship 1 provided in this embodiment can travel in the sea or river, and can transfer the batteries 2 stored in itself to the electric boat 3 that needs to replace the power batteries 2 through the lower transfer device 200 and the upper transfer device. Charging can be completed without the electric boat 3 interrupting navigation, ensuring that the electric boat 3 replaces the batteries 2 while sailing.

[0040] In detail, a first guide rail 320 extending along the length direction is provided on the top of the mounting frame 360, and a second guide rail extending along the width direction is also provided on the first guide rail 320, and the second guide rail is connected to the first guide rail 320, and the second guide rail can move along the length direction on the first guide rail 320, and a sling lifting mechanism 380 is installed on the second guide rail, and the sling lifting mechanism 380 can move along the width direction on the second guide rail, and the sling lifting mechanism 380 is connected to the sling 370, and the sling lifting mechanism 380 is used to drive the sling 370 to move in the height direction, and the length direction is perpendicular to the width direction.

[0041] It should be noted that both the first guide rail 320 and the second guide rail are spaced apart from the upper deck 300 in the height direction.

[0042] In this embodiment, the length direction can be understood as the length direction of the battery swap ship 1 , and the width direction can be understood as the width direction of the battery swap ship 1 .

[0043] It can be understood that the first guide rail 320 and the second guide rail can ensure that the sling 370 can move in the length and width directions. When the battery swap ship 1 needs to transfer the battery 2 to the moving electric boat 3, due to the changeable environment in the sea or river, the battery swap ship 1 and the electric boat 3 are prone to relative displacement. Through the setting of the first guide rail 320 and the second guide rail, it can promptly drive the sling 370 to move in the length or width direction to adapt to the relative displacement between the battery swap ship 1 and the electric boat 3.

[0044] The mounting frame 360 ​​further includes a first driving member 321, which is used to drive the second guide rail to move in the length direction. The sling lifting mechanism 380 is connected to a second driving member 381, which is used to drive the sling lifting mechanism 380 on the second guide rail along the width direction.

[0045] In this embodiment, the second guide rail includes a movable guide rail 330 and a telescopic guide rail both extending in the width direction. The movable guide rail is connected to the first guide rail 320 and can move in the length direction. The telescopic guide rail is installed on the movable guide rail 330 and can move in the width direction relative to the movable guide rail 330 to extend the movable guide rail 330 or retract the movable guide rail 330. The sling lifting mechanism 380 is installed on the telescopic guide rail and can move on the telescopic guide rail in the telescopic width direction.

[0046] It can be understood that by setting the movable guide rail 330 and the telescopic guide rail, the moving range of the sling 370 in the width direction can be increased, and the relative displacement between the battery-swap boat 1 and the electric boat 3 in motion can be further adapted.

[0047] It should be noted that the movable guide rail 330 is provided with a first transmission member, the telescopic guide rail is provided with a second transmission member that cooperates with the first transmission member, and the upper transfer device also includes a telescopic driving member 331, which is used to drive the first transmission member or the second transmission member to drive the telescopic guide rail to move in the width direction.

[0048] Optionally, one of the first transmission member and the second transmission member is a transmission gear, and the other of the first transmission member and the second transmission member is a transmission rack.

[0049] In some embodiments, the first transmission member is a transmission gear, the second transmission member is a transmission rack, the transmission rack is installed on the outer wall of the telescopic guide rail, and the telescopic driving member 331 is a driving motor, which is installed on the movable guide rail 330.

[0050] It can be understood that, by providing the transmission rack and the transmission gear, the accuracy and stability of the telescopic guide rail when it moves relative to the movable guide rail 330 in the width direction can be improved.

[0051] In this embodiment, there are two first guide rails 320 and the two first guide rails 320 are installed on the top of the mounting frame 360 ​​at intervals along the width direction. The two ends of the movable guide rail 330 along the width direction are respectively rollingly matched with the two first guide rails 320.

[0052] It can be understood that the friction force when the movable guide rail 330 moves relative to the first guide rail 320 in the length direction can be reduced by rolling fit, thereby facilitating the movable guide rail 330 to move in the length direction on the first guide rail 320. In addition, since the two ends of the movable guide rail 330 in the width direction are respectively in rolling fit with the two first guide rails 320, the supporting capacity of the first guide rail 320 for the movable guide rail 330 is also guaranteed, and the stability of the movable guide rail 330 moving on the first guide rail 320 is guaranteed.

[0053] The first guide rail 320 is provided with a roller groove extending along the length direction, and the movable guide rail 330 is installed with a roller that rolls with the roller groove, wherein the movable guide rail 330 is also provided with a driving motor connected with the roller.

[0054] Of course, in some other embodiments, the movable guide rail 330 and the first guide rail 320 can also have other types of cooperation, such as sliding cooperation, that is, the first guide rail 320 is provided with a slide groove extending along the length direction, the movable guide rail 330 is provided with a slider that slides with the slide groove, and the first guide rail 320 is installed with a driving structure for driving the movable guide rail 330.

[0055] In some embodiments, the telescopic rail may include a first telescopic arm 340 and a second telescopic arm 350, both of which extend in the width direction. The first telescopic arm 340 is installed on the movable rail 330 and can move in the width direction on the movable rail 330. The second telescopic arm 350 is installed on the first telescopic arm 340 and can move in the width direction relative to the first telescopic arm 340. The hoisting device lifting mechanism 380 is installed on the second telescopic arm 350. The arrangement of the first telescopic arm 340 and the second telescopic arm 350 can further adapt to the relative displacement between the battery swapping boat 1 and the moving electric boat 3.

[0056] That is to say, the first driving member 321 is used to drive the movable guide rail 330 to move in the length direction of the first guide rail 320, and the second driving member 381 is used to drive the sling lifting mechanism 380 to move along the width direction on the second telescopic arm 350, wherein the mounting frame 360 ​​is also provided with a third driving member 341, and the third driving member 341 is used to drive the second telescopic arm 350 to move along the width direction on the first telescopic arm 340, and the telescopic driving member 331 is used to drive the first telescopic arm 340 to move along the width direction on the movable guide rail 330.

[0057] In this embodiment, the first driving member 321 is installed on the movable guide rail 330, and the movable guide rail 330 is equipped with a running wheel that rolls with the first guide rail 320. The first driving motor 321 is used to drive the running wheel on the movable guide rail 330 to rotate so that the movable guide rail moves along the length direction on the first guide rail 320.

[0058] When the second driving member 281 or the third driving member 341 is a driving motor, the second driving member 381 can enable the sling lifting mechanism 380 to move along the width direction on the second telescopic arm 350 through a transmission assembly. The transmission assembly may include a transmission gear and a transmission rack that are transmission-connected, that is, a transmission gear is connected to the driving shaft on the second driving member 381, and a transmission rack is installed on the second telescopic arm 350.

[0059] Optionally, the second telescopic arm 350 is provided with an opening for movement of the sling lifting mechanism 380 , the opening is arranged along the extension direction of the second telescopic arm 350 , and a transmission rack matched with the transmission gear is installed on the inner wall of the opening.

[0060] Similarly, the third drive motor 341 can also use a transmission assembly to make the second telescopic arm 350 move on the first telescopic arm 340. The transmission assembly can also be a transmission gear and a transmission rack connected in a transmission manner. For example, the third drive member 341 can be installed on the first telescopic arm 340, and a transmission gear is installed on the driving shaft of the third drive member 341, and a transmission rack is installed on the outer peripheral wall of the second telescopic arm 350.

[0061] Please refer to Figure 3-Figure 4 Optionally, in some embodiments, the sling 370 includes a mounting plate 371, a hook 372 and a guide block 373. The number of the hooks 372 is four and they are arranged in a rectangular array and installed on the mounting plate 371. The hooks 372 can rotate relative to the mounting plate 371 to switch between the storage and hooking states. It can be understood that the four hooks 372 can be respectively connected to the four ears of a battery 2 to improve the stability of the transportation of the battery 2.

[0062] It is easy to understand that the mounting plate 371 is also provided with a hook 372 driving member for driving the four hooks 372 to rotate. When the hook 372 is in a hooked state, the hook 372 extends out of the mounting plate 371 to be connected to the lifting ear of the battery 2 so as to lift the battery 2. This is a conventional method in the field of the sling 370 and will not be elaborated here.

[0063] The guide block 373 is arranged on the outside of the four hooks 372 . It can be understood that the setting of the guide block 373 can play a certain guiding role for the sling 370 when slinging the battery 2 , making it easier for the sling 370 to complete the installation of the battery 2 .

[0064] In some optional embodiments, in order to improve the accuracy of the hook 372 rotating to the hook state, four in-position switches 375 corresponding to the four hooks 372 are further provided on the mounting plate 371. The four in-position switches 375 are used to respectively detect whether the four hooks 372 are rotated into position, that is, whether they are rotated to the hook state and the storage state.

[0065] Of course, in some other embodiments, the hanger 370 may also be other types of hangers 370 , and the structure of the hanger 370 is not limited herein.

[0066] It should be noted that the above-mentioned sling lifting mechanism 380 is used to drive the sling 370 to move in the height direction, wherein the sling lifting mechanism 380 can drive the sling 370 to move in the height direction through the wound steel wire. For example, the mounting plate 371 of the sling 370 is provided with a plurality of steel wire ropes, and the fixed ends of the steel wire ropes are fixedly connected to the mounting plate 371. The sling lifting mechanism 380 is provided with a plurality of steel wire ropes corresponding to the plurality of steel wire ropes one by one. The steel wire rope winders are connected to the movable ends of the steel wire ropes, and the steel wire rope winders drive the steel wire ropes to wind, thereby driving the sling 370 to move in the height direction.

[0067] Among them, in this embodiment, a second driving component 381 is provided on the sling lifting mechanism 380, and the second driving component 381 is a driving motor. A traveling gear is installed on the driving end of the driving motor. In this embodiment, a rack that cooperates with the traveling gear transmission is provided on the telescopic guide rail. Driven by the driving motor, the sling lifting mechanism 380 can be driven to move in the extension direction of the telescopic guide rail.

[0068] Optionally, the upper deck 300 is provided with an upper installation position, the mounting frame 360 ​​is arranged around the upper installation position, the upper installation position is provided with a battery base 390 for installing the battery 2, and the upper installation position is provided with a transfer channel 310.

[0069] It is understandable that the upper installation position is also provided with a battery base 390 for installing the battery 2, that is, the upper transfer device can also transfer the battery 2 at the first transfer position 100 to the upper installation position. It is understandable that due to the setting of the upper installation position, the number of installed batteries 2 can be increased, so that the battery-swapping ship 1 can replace power batteries 2 for multiple electric ships 3.

[0070] It can be understood that since the mounting frame 360 ​​is arranged around the upper mounting position, it can enable the hanger 370 to hang the battery 2 at any position in the upper mounting position under the action of the first guide rail 320 and the movable guide rail 330.

[0071] In detail, the lower-level transfer device 200 includes a transfer frame 210, a third guide rail 220 and a battery-swapping transfer fixture 240. The third guide rail 220 is installed on the transfer frame 210, and the third guide rail 220 extends along the length direction. The battery-swapping transfer fixture 240 is connected to the third guide rail 220 and can move relative to the third guide rail 220 along the length direction.

[0072] It should be noted that the third guide rail 220 and the bottom surface of the lower battery 2 storage compartment are at a certain height, so that the battery replacement transport fixture 240 can move in the height direction to transport the battery 2 in the lower battery 2 storage compartment.

[0073] Please continue to refer to Figure 5-Figure 6In this embodiment, the lower transfer device 200 also includes a fourth guide rail 230 extending along the width direction, the fourth guide rail 230 is connected to the third guide rail 220 and can move along the length direction on the third guide rail 220, and the battery exchange transfer fixture 240 is installed on the fourth guide rail 230 and can move along the width direction on the fourth guide rail 230.

[0074] By setting the third guide rail 220 and the fourth guide rail 230, it can ensure that the battery replacement transport fixture 240 can lift the battery 2 at any location in the lower battery 2 storage compartment to improve the transportation efficiency of the battery 2.

[0075] It should be noted that, in the present embodiment, the battery exchange transport fixture 240 may include the above-mentioned connected hanger 370 and hanger lifting mechanism 380, or may be other types of fixtures.

[0076] In order to improve the stability of the movement of the fourth guide rail 230 on the third guide rail 220, and thereby improve the stability of the transportation of the battery 2, the number of the third guide rails 220 is two and the two third guide rails 220 are arranged at intervals on the transfer frame 210 along the width direction, and the two ends of the fourth guide rail 230 in the width direction are respectively rollingly matched with the two third guide rails 220.

[0077] Among them, the transfer frame 210 is provided with a fifth driving member 221 and a sixth driving member 231. The fifth driving member 221 is used to drive the fourth guide rail 230 to move along the length direction on the third guide rail 220, and the sixth driving member 231 is used to drive the battery replacement transfer fixture 240 to move along the width direction on the fourth guide rail 230.

[0078] The specific driving structure of the fifth driving member 221 and the sixth driving member 231 is not limited here. The fifth driving member 221 and the sixth driving member 231 can be linear driving rods or driving motors. When the fifth driving member 221 or the sixth driving member 231 is a linear driving member, the fifth driving member 221 can directly drive the fourth guide rail 230 to move in the length direction, and the sixth driving member 231 can directly drive the battery exchange transport fixture 240 to move along the width direction on the fourth guide rail 230, wherein the linear driving member can be a driving cylinder or a driving electric cylinder.
