Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0034] See Figure 1 and Figure 2This utility model provides a ship battery swapping station, including a foundation 1, at least one ship berthing position 2 on the side of the foundation 1, at least one battery swapping robot 3 and at least one battery compartment 4 on the foundation 1, a first displacement mechanism 5 between the battery swapping robot 3 and the foundation 1, the battery swapping robot 3 moves to a suitable battery swapping position through the first displacement mechanism 5, the battery swapping robot 3 includes a support frame and a boom 32 mounted on the support frame, wherein the boom 32 has a reach of 10 meters or more, the support frame spans across the battery compartment 4, the first end of the boom 32 is located at the first end of the support frame, the second end of the boom 32 passes through the support frame and extends from the second end of the support frame to above the ship berthing position 2, the boom 32 is equipped with a second displacement mechanism 6, a lifting mechanism driven by the second displacement mechanism 6, and a lifting device 33 driven by the lifting mechanism, the second displacement mechanism 6 adjusts the horizontal position of the lifting device 33 and the battery compartment 81, the lifting mechanism adjusts the vertical position of the lifting device 33 and the battery compartment 81, the lifting device 33 moves between the ship berthing position 2 and the battery compartment 4, and the battery swapping robot 3 includes a support frame and a lifting arm 32 mounted on the foundation 1, at least one ship berthing position 2, at least one ship berthing position 2, at least one battery swapping robot 3 ... The depleted battery box 81 on the ship is transported to the battery compartment 4, and the fully charged battery box 81 in the battery compartment 4 is transported to the ship to complete the battery swap. This utility model sets the ship berthing position 2 on the side of the foundation 1, and the battery swapping robot 3 completes the transportation of the battery box 81 between the ship berthing position 2 and the battery compartment 4. There is no need to use vehicles to deliver the battery box 81, which effectively reduces the battery swapping transfer process, simplifies the entire battery swapping process, and avoids the phenomenon of the battery box 81 falling or being damaged due to the cumbersome battery swapping transfer process, thus improving the overall working stability and safety. The battery swapping robot 3 adopts a brand-new structure. Through multi-axis linkage, it can adjust the position of the battery box 81 in multiple directions, so that it can be accurately installed on the ship or placed in the battery compartment 4, effectively improving the battery swapping accuracy and realizing flexible intelligent battery swapping, thereby improving the battery swapping efficiency. The battery swapping robot 3 adopts a horizontal structure, which spans across the battery compartment 4 and the ship berthing position 2 to transport the battery box 81. The vertical horizontal structure replaces the conventional horizontal laying structure, effectively reducing the footprint of the battery swapping robot 3.

[0035] As one embodiment of this utility model, a counterweight 34 is provided at the first end of the boom 32. The counterweight 34 can prevent the support frame from tipping over towards the second end of the boom 32 due to the excessive weight of the battery box 81, effectively improving the safety and stability of the battery swapping robot 3. Preferably, there are multiple counterweights 34, and the weights of the multiple counterweights 34 are different. The operator can select the appropriate counterweight 34 according to the weight of the specific battery box 81, thereby improving the applicability. The battery swapping robot 3 can lift loads of up to 30 tons or more, which greatly improves the safety and reliability of lifting heavy objects.

[0036] As one embodiment of this utility model, the support frame includes a frame spanning above the battery compartment 4. A support beam 311 is provided above the frame. At least one connecting beam 312 is provided between the support beam 311 and the frame. At least one first steel wire rope 313 is provided between the support beam 311 and the part of the boom 32 extending out of the support frame. The support beam 311, the connecting beam 312 and the first steel wire rope 313 can apply an upward pulling force to the boom 32, which can prevent the boom 32 from breaking or being damaged due to the excessive weight of the battery box 81, and can further improve the safety and stability of the battery swapping robot 3.

[0037] As one embodiment of this utility model, the frame can adopt various shapes and structures, such as triangles, trapezoids, rhombuses, or other irregular shapes. Preferably, the frame is a hollow cuboid shape. The frame includes multiple horizontal beams 314, multiple vertical beams 315, and multiple vertical beams 316. The horizontal beams 314 are parallel to the movement direction of the first displacement mechanism 5, and the vertical beams 315 are perpendicular to the horizontal beams 314. Since the frame moves above the battery compartment 4, the height of the vertical beams 315 is greater than the height of the battery compartment 4, which avoids interference or collision between the battery swapping robot 3 and the battery compartment 4 during the movement, and ensures the safety of the battery swapping robot 3 and the battery compartment 4.

[0038] As one embodiment of this utility model, the support beam 311 and the connecting beam 312 can be structurally adjusted according to specific usage requirements, and the following three structures can be adopted:

[0039] Structure 1: A connecting beam 312 is provided between the support beam 311 and the top corner of the frame. The support beam 311 is located on the side of the frame near the second end of the boom 32. The support beam 311 is connected to the four top corners of the frame, which improves the connection strength between the support beam 311 and the frame. The four connecting beams 312 can distribute the force on the frame, improve the uniformity of the force on the frame, and improve the service life of the connecting beams 312 and the frame.

[0040] Structure 2: Support beam 311 and connecting beam 312 are located in the middle of the frame;

[0041] Structure 3: The connecting beam 312 is located in the middle of the top horizontal beam 314 of the frame, or in the middle of the top longitudinal beam 315 of the frame.

[0042] Of course, the structure and position of the support beam 311 and the connecting beam 312 are not limited to the three types mentioned above. The connecting beam 312 only needs to ensure the connection strength between the support beam 311 and the frame.

[0043] As one embodiment of this utility model, there are multiple first wire ropes 313. The first wire rope 313 is provided at the midpoint of the extended part of the boom 32, between the second end of the boom 32 and the support beam 311, so as to provide the boom 32 with the maximum upward tension. The first wire rope 313 is also provided at the midpoint of the extended part of the boom 32, so that the tension provided to the boom 32 has a certain uniformity. This avoids the uneven upward tension caused by the boom 32 being too long, which would eventually lead to damage or collapse of the middle part of the extended part of the boom 32, and further improves the overall reliability and stability.

[0044] As an embodiment of the present invention, the second displacement mechanism 6 includes a track arranged along the direction of the boom 32, a displacement trolley moving along the track, and a first motor driving the displacement trolley to move. The first motor drives the displacement trolley to move along the track to adjust the position of the lifting device 33 and the battery box 81 in the X direction, where the X direction is the extension direction of the boom 32.

[0045] As one embodiment of this utility model, the lifting mechanism includes a second motor mounted on the second displacement mechanism 6 and a second drum 71 driven by the second motor. A second steel wire rope 72 is wound on the second drum 71 and is connected to the lifting device 33. The second motor drives the second drum 71 to rotate, so as to wind and unwind the second steel wire rope 72, thereby raising and lowering the lifting device 33. This allows the operator to adjust the vertical position of the lifting device 33 and the battery box 81 after determining the horizontal position of the lifting device 33, so as to lift or lower the battery box 81. Preferably, the lifting device 33 is provided with a movable pulley, and the second steel wire rope 72 is wound on the movable pulley. When the second steel wire rope 72 is wound, the movable pulley and the lifting device 33 rise; when the second steel wire rope 72 is unwound, the movable pulley and the lifting device 33 descend.

[0046] As one embodiment of this utility model, there are four second drums 71, four second wire ropes 72, and four movable pulleys. The second drums 71, the second wire ropes 72, and the movable pulleys correspond one-to-one. The four movable pulleys are evenly arranged on the top of the lifting device 33, so that the lifting device 33 is subjected to uniform force. This can prevent the battery box 81 from tipping over due to uneven force on the lifting device 33, thus avoiding unnecessary damage to the battery box 81 and improving the overall safety and stability of use.

[0047] As an embodiment of this utility model, the first displacement mechanism 5 includes a ground rail 51 set on the foundation 1, a support frame with a walking wheel 52 moving along the ground rail 51, and a third motor driving the walking wheel 52. That is, the walking wheel 52 is set on the bottom crossbeam 314, and the ground rail 51 is set perpendicular to the boom 32. That is, the third motor drives the battery swapping robot 3 to move along the ground rail 51 to adjust the position of the battery swapping robot 3 in the Y direction, which is perpendicular to the boom 32. The first displacement mechanism 5 and the second displacement mechanism 6 cooperate with each other to realize the adjustment of the horizontal position of the lifting device 33. Preferably, there are two ground rails 51, which are set in parallel and are respectively set on both sides of the battery compartment 4. The bottom crossbeams 314 on both sides of the battery swapping robot 3 are respectively provided with walking wheels 52, so that the battery swapping robot 3 has a stable support force and further improves the working stability and reliability of the battery swapping robot 3.

[0048] As an embodiment of this utility model, guide rail slider groups are provided between the displacement trolley and the boom 32, and between the battery swapping robot 3 and the foundation 1, and a guide rod is provided between the lifting device 33 and the second displacement mechanism 6.

[0049] See Figure 3-6 As an embodiment of the present utility model, the lifting device 33 includes a body 331 connected to the lifting mechanism, a drive assembly disposed on the body 331, and a first limiting part driven by the drive assembly. The first limiting part has a first position and a second position, and the battery box 81 is provided with a second limiting part that cooperates with the first limiting part.

[0050] The first limiting part is located in the first position, and the first limiting part is engaged with the second limiting part;

[0051] The first limiting part is located in the second position, and the first limiting part is separated from the second limiting part.

[0052] During operation, the first limiting part is initially located in the second position. When the first limiting part moves to the appropriate working position, the drive component drives the first limiting part to switch from the second position to the first position. The first limiting part and the second limiting part engage, completing the fixed connection between the lifting device 33 and the battery box 81. When the lifting device 33 carries the battery box 81 to the designated position, the drive component drives the first limiting part to switch from the first position to the second position. The first limiting part and the second limiting part separate, thus separating the lifting device 33 from the battery box 81 and completing the transportation of the battery box 81.

[0053] As an embodiment of this utility model, the first limiting part includes a limiting rod 332 disposed at the driving end of the driving component and a first limiting block 333 disposed at the end of the limiting rod 332 away from the driving component; the second limiting part includes a second limiting block 811 disposed on the battery box 81, the second limiting block 811 having a hollow cavity inside, and a limiting hole 812 communicating with the hollow cavity at the top of the second limiting block 811; the first limiting block 333 is inserted into the hollow cavity from the limiting hole 812 in a second position and can rotate in the hollow cavity, realizing the switching of the first limiting block 333 between a first position and a second position, that is, when the first limiting block 333 is in the second position, it can pass through the limiting hole 812, and the lifting device 33 and the battery box 81 can be separated, while when the first limiting block 333 is in the first position, it cannot pass through the limiting hole 812, thus realizing the fixed connection between the lifting device 33 and the battery box 81.

[0054] In one embodiment of this utility model, the driving assembly includes a turntable 334 and a driving rod 335 mounted on the body 331. The turntable 334 is horizontally positioned, and its bottom end is connected to a first limiting part. A guide groove is provided on the circumferential surface of the turntable 334. The driving rod 335 is vertically positioned, and a driving part 3351 extending outward in the radial direction is provided on the circumferential surface of the driving rod 335. The driving part 3351 is inserted into the guide groove, and the turntable 334 is driven to rotate by the vertical movement of the driving rod 335. The guide groove includes four drive guide grooves 3341 connected end to end and a restoration guide groove. One drive guide groove 3341 and one restoration guide groove constitute a set. The turntable 334 occupies 1 / 4 of the circumference. After the drive unit 3351 passes through a drive guide groove 3341 and a restoration guide groove, the turntable 334 rotates 90°, realizing the switching of the first limit block 333 between the first position and the second position. The drive guide groove 3341 is inclined upward, and the restoration guide groove includes a vertically arranged vertical part 3342 and an inclined part 3343 inclined downward. The top of the drive guide groove 3341 is connected to the top of the vertical part 3342, the bottom of the vertical part 3342 is connected to the top of the inclined part 3343, and the bottom of the inclined part 3343 is connected to the bottom of the next drive guide groove 3341.

[0055] Working process: The first limiting block 333 is initially in the second position, and the drive rod 335 is initially located at the bottom of the drive guide groove 3341. The first limiting block 333 first enters the hollow cavity through the limiting hole 812. After the lifting device 33 contacts the battery box 81, as the lifting device 33 descends, the upper surface of the battery box 81 applies an upward thrust to the bottom of the drive rod 335, causing the drive rod 335 to move upward. The drive unit 3351 moves along the drive guide groove 3341 and drives the turntable 334 to rotate. The first limiting block 333 switches from the second position to the first position. At this time, the first... The limiting block 333 cannot pass through the limiting hole 812, thus completing the fixed connection between the lifting device 33 and the battery box 81. Subsequently, the lifting mechanism slowly lifts the lifting device 33, and the battery box 81 separates from the drive rod 335. The thrust exerted by the battery box 81 on the bottom of the drive rod 335 is eliminated, and the drive rod 335 moves downward under its own weight. The drive part 3351 moves along the recovery guide groove and falls to the bottom of the inclined part 3343, which is the bottom of the next drive guide groove 3341, in preparation for the next position switch. At the same time, the battery swapping robot 3 transports the battery box 81.

[0056] Once the lifting device 33 and battery box 81 reach the designated position above, the lifting mechanism slowly lowers them. As the lifting device 33 descends, the upper surface of the battery box 81 applies an upward thrust to the bottom of the drive rod 335, causing the drive rod 335 to move upward. The drive unit 3351 moves along the drive guide groove 3341 and drives the turntable 334 to rotate. The first limiting block 333 switches from the first position to the second position. At this time, the first limiting block 333 can pass through the limiting hole 812. Subsequently, the lifting mechanism lifts the lifting device 33. The limiting block 333 separates the lifting device 33 from the battery box 81 through the limiting hole 812. As the lifting device 33 rises, the battery box 81 separates from the drive rod 335. The thrust exerted by the battery box 81 on the bottom of the drive rod 335 is eliminated. The drive rod 335 moves downward under its own weight. The drive part 3351 moves along the recovery guide groove and falls to the bottom of the inclined part 3343, that is, the bottom of the next drive guide groove 3341, in preparation for the next position switch. At this time, the battery swapping robot 3 completes the transportation of the battery box 81.

[0057] This invention uses a turntable 334 and a drive rod 335 instead of a conventional motor to switch the position of the first limiting part. After the lifting device 33 contacts the battery box 81, the first limiting part can automatically switch from the second position to the first position, so that the lifting device 33 and the battery box 81 are fixedly connected. When the lifting device 33 moves the battery box 81 to the designated position, the first limiting part can automatically switch from the first position to the second position, so that the lifting device 33 and the battery box 81 are separated, realizing the automatic switching of the position of the first limiting part, improving work stability and work efficiency.

[0058] In one embodiment of this utility model, the bottom end of the inclined portion 3343 is inserted into the drive guide groove 3341. That is, when the drive portion 3351 falls to the bottom end of the inclined portion 3343, it is in the drive guide groove 3341 and no longer corresponds to the vertical portion 3342. Therefore, when the drive portion 3351 is subjected to an upward thrust, the drive portion 3351 moves upward and contacts the top guide surface of the drive guide groove 3341. Then, under the guidance of the guide surface, it moves upward along the drive guide groove 3341, avoiding the drive portion 3351 from moving upward along the vertical portion 3342, thereby further improving the overall working stability and reliability.

[0059] See Figure 5 As an embodiment of this utility model, the battery compartment 4 is provided with multiple battery box storage positions for storing battery boxes 81, a charger 82 for charging the battery boxes 81, and a water cooler 83 for cooling the battery boxes 81. The water cooler 83 can prevent the battery boxes 81 from overheating during charging or discharging, thereby improving charging safety and reliability.

[0060] As an embodiment of this utility model, a fire pool is provided on the foundation 1. The bottom of the fire pool is connected to the water body. The fire pool is filled with liquid for a long time. When the battery box 81 is abnormal during the battery swapping process, the battery swapping robot 3 can put the abnormal battery box 81 into the fire pool to extinguish the fire and improve the safety of the battery swapping process.

[0061] In one embodiment of this utility model, the number of battery swapping robots 3 is greater than the number of ship berths 2. Each battery swapping robot 3 corresponds to one ship berth 2, meaning that at least one battery swapping robot 3 is in standby mode. When a battery swapping robot 3 in operation malfunctions, the staff can immediately activate the standby battery swapping robot 3 to perform the replacement operation, thus achieving redundancy of the battery swapping robots 3. This avoids the impact of battery swapping robot 3 malfunctions on the battery swapping work, effectively improving the continuity and stability of the battery swapping operation. Preferably, the number of redundant battery swapping robots 3 is one, which can reduce the capital investment in battery swapping robots 3 and reduce the operating cost.

[0062] In summary, this utility model provides a ship battery swapping station. The ship berth 2 is located on the side of the foundation 1. A battery swapping robot 3 transports the battery box 81 between the ship berth 2 and the battery compartment 4, eliminating the need for vehicle delivery of the battery box 81. This effectively reduces the battery swapping transfer process, simplifies the entire swapping workflow, and avoids the possibility of the battery box 81 falling or being damaged due to cumbersome transfers, thus improving overall operational stability and safety. The battery swapping robot 3, with its novel structure, can adjust the position of the battery box 81 in multiple directions through multi-axis linkage, allowing for precise installation on the ship or placement within the battery compartment 4, effectively improving swapping accuracy and achieving flexible intelligent swapping, thereby increasing swapping efficiency. The horizontally spanning battery swapping robot 3 spans above the battery compartment 4 and the ship berth 2 to transport the battery box 81. The vertical spanning structure replaces the conventional horizontal laying structure, effectively reducing the footprint of the battery swapping robot 3. First steel wire ropes 3 are installed at the midpoint of the extended portion of the boom 32, between the second end of the boom 32 and the support beam 311. 13. It can provide maximum upward pulling force to the boom 32, making the pulling force provided to the boom 32 relatively uniform. This avoids uneven upward pulling force caused by the boom 32 being too long, which could lead to damage or collapse of the middle part of the boom 32 extension. This further improves the overall reliability and stability. A turntable 334 and a drive rod 335 are used instead of a conventional motor to switch the position of the first limiting part. After the lifting device 33 contacts the battery box 81, the first limiting part can automatically switch from the second position to the first position, so that the lifting device 33 and the battery box 81 are fixedly connected. When the lifting device 33 moves the battery box 81 to the designated position, the first limiting part can automatically switch from the first position to the second position, so that the lifting device 33 and the battery box 81 are separated. This realizes automatic switching of the position of the first limiting part, improving work stability and work efficiency. At least one battery swapping robot 3 is in standby mode, realizing the redundancy of the battery swapping robot 3. This avoids the impact of battery swapping work due to the failure of the battery swapping robot 3, effectively improving the continuity and stability of battery swapping operations.

[0063] It should be emphasized that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model in any way. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
