Description

Technical Field

[0001] The present invention relates to the technical field of ship power replacement, and in particular to a ship power replacement system and method. Background Art

[0002] As the world pays more attention to environmental protection and sustainable development, electric ships are in line with the development trend of the future shipping industry. Electric ships can reduce pollution to the environment when in operation, which helps to improve air quality. Electric ships have lower noise levels, which helps to reduce noise pollution. Electric ships reduce dependence on oil resources, and electricity is usually cheaper than fuel oil, which can save a lot of fuel costs in long-term operation. At present, electric ships can quickly replenish electricity by directly replacing battery boxes.

[0003] The current battery replacement technology is to hoist the battery box from the shore to the top of the ship in the water. There is no fixed device to fix the ship in the water, and the ship is prone to shaking. During the installation process, it is difficult to hoist the battery box to the corresponding position on the ship. This may increase the time consumption of the battery replacement process and affect the operating efficiency of the ship. When the shaking is severe, the battery box may collide with various components on the ship during installation, causing damage to the battery box and posing a potential safety hazard.

[0048] At present, electric ships can quickly replenish electricity by directly replacing battery boxes. Since electric ships are not fixed in the water, the water surface is prone to fluctuations during the battery replacement process, causing the ship to shake, making it difficult to lift the battery box 40 to the corresponding position on the ship, reducing the lifting efficiency of the battery box 40 and affecting the ship's operating efficiency. In order to solve the problem of how to quickly lift the battery box 40 during the ship's battery replacement process, a ship battery replacement system is proposed. Figure 2 As shown, the ship power exchange system may include a hull assembly 20, a battery box 40, a fixing assembly 10, and a hoisting assembly 30. The hoisting assembly 30 may be arranged in a shore port or on other ships.

[0049] The hull assembly 20 can float on the water surface without any fixing device to fix the hull assembly 20, so the hull assembly 20 is prone to shaking during the battery replacement process, affecting the battery replacement efficiency. Figure 1 As shown, the fixing assembly 10 may include a first bottom bracket unit 11, a first guide unit 12, and a second guide unit 13. The first bottom bracket unit 11 may be detachably connected to the hull assembly 20. The first bottom bracket unit 11 is convenient for installation and separate maintenance, and the first bottom bracket unit 11 may support the battery box 40. One end of the first guide unit 12 may be detachably connected to the first bottom bracket unit 11, and the other end may extend in a direction away from the hull assembly 20. The area of ​​the first guide unit 12 along the horizontal direction may gradually decrease from the hull assembly 20 to the first bottom bracket unit 11, so that the first guide unit 12 may partially form an inclined surface. A fixing hole may be provided at the bottom end of the battery box 40, and the fixing hole is recessed from the bottom end of the battery box 40 toward the top end of the battery box 40, and the fixing hole may be adapted to the first guide unit 12. In this way, when the battery box 40 is hoisted and lowered to abut against the inclined surface of the first guide unit 12, when the battery box 40 is shaken and offset, the battery box 40 may slide on the inclined surface as the battery box 40 is lowered. Thereby, the battery box 40 can be within the vertical projection range of the first base unit 11 and the battery box 40 can be abutted against the first base unit 11. When the battery box 40 abuts against the first base unit 11, the fixing hole is sleeved on the outer peripheral side of the first guide unit 12. The first guide unit 12 helps to reduce the displacement of the battery box 40 in the width direction of the hull assembly 20. When the hull assembly 20 shakes during the battery replacement process, the battery box 40 is guided by the first guide unit 12, thereby improving the battery replacement efficiency. The second guide unit 13 may include two first guide modules 131 and a driving unit. One end of the first guide module 131 can be movably connected to the first base unit 11, and the other end can extend in a direction away from the hull assembly 20. The driving unit can be drivably connected to the first guide module 131, and drive the first guide module 131 to rotate with the connection between the first guide module 131 and the first base unit 11 as the rotation axis. It is convenient for the driving unit to drive the two first guide modules 131 to rotate, such as Figure 3 As shown, the two first guide modules 131 are gradually retracted until they are respectively in contact with the left and right sides of the battery box 40. The contact between the battery box 40 and the first guide modules 131 can effectively suppress the relative shaking and deviation between the battery box 40 and the first bottom bracket unit 11 during the descent of the battery box 40. The hull assembly 20 is more prone to shaking in the width direction than in the length direction, so the two first guide modules 131 can be spaced apart on both sides of the first bottom bracket unit 11 along the first direction. The angle between the first direction and the width direction of the hull assembly 20 can be within a first set range (such as 0° to 5°), thereby reducing the relative shaking of the battery box 40 and the hull assembly 20 in the width direction of the hull assembly 20. As shown in FIG. Figure 8 As shown, A may be the distance between the two first guide modules 131 away from the side of the hull assembly 20 along the first direction, B may be the size of the first bottom bracket unit 11 along the first direction, and A may be greater than or equal to B. Figure 3 As shown, the driving unit can drive the two first guide modules 131 to gradually retract to the left and right sides of the battery box 40 and respectively abut against the two first guide modules 131, so as to control the shaking of the battery box 40 relative to the width direction of the hull assembly 20 during the descent process. C can be the distance between the first guide module 131 away from one end of the hull assembly 20 and the first bottom bracket unit 11 along the height direction of the battery box 40, and D can be the distance between the first guide unit 12 away from one end of the hull assembly 20 and the first bottom bracket unit 11 along the height direction of the battery box 40, and C can be greater than D. In this way, during the descent of the battery box 40, after the battery box 40 abuts against the first guide module 131, the first guide module 131 can first control the shaking relative to the width direction of the hull assembly 20, and the battery box 40 continues to descend. Under the action of the first guide module 131 controlling the shaking of the battery box 40 relative to the width direction of the hull assembly 20, the first guide unit 12 can further guide the battery box 40 to slide on the inclined surface of the first guide unit 12, and move the battery box 40 to the vertical projection range of the first bottom bracket unit 11 and the battery box 40 abuts against the first bottom bracket unit 11, thereby completing the lifting of the battery box 40. In this way, the battery box 40 can be quickly lifted during the ship's power replacement process, so that the battery box 40 and the first bottom bracket unit 11 are smoothly installed, which improves the lifting efficiency of the battery box 40 and thus improves the operating efficiency of the ship. The hull assembly 20 can be spaced apart from the lifting assembly 30. The spacing between the hull assembly 20 and the lifting assembly 30 can effectively prevent the battery box 40 from colliding with the hull assembly 20 during the lifting process, thereby avoiding damage to the battery box 40 or the hull assembly 20 and improving the safety of the lifting operation.

[0050] The fixing assembly 10 may include a first state and a second state. The first state may include the hoisting assembly 30 gradually retracting the two first guide modules 131 during the descent of the battery box 40 until the battery box 40 abuts against the first guide modules 131, so that the two first guide modules 131 can control the shaking of the battery box 40 relative to the width direction of the hull assembly 20 during the descent. The second state may include the battery box 40 being within the vertical projection range of the first bottom bracket unit 11 and the battery box 40 abutting against the first bottom bracket unit 11, so that the battery box 40 and the first bottom bracket unit 11 are detachably connected. At this time, the battery box 40 can complete the installation with the first bottom bracket unit 11.

[0051] In other embodiments, the lifting assembly 30 may include a lifting seat 31, a second lifting part 32, and a second grabbing part 33. The second grabbing part 33 may be movably connected to the second lifting part 32. After the second lifting part 32 is lowered to abut against the top surface of the battery box 40, the second grabbing part 33 grabs the battery box 40. The lifting seat 31 may be detachably connected to the second lifting part 32, so that the second lifting part 32 can be installed and maintained separately.

[0052] In some embodiments, the first guide module 131 may include a first frame 1311, a second frame 1312, and a first rolling body 1313. One end of the first frame 1311 may be movably connected to the first support unit 11, and the other end may extend in a direction away from the hull assembly 20. The driving unit may be drivably connected to the first frame 1311, and used to drive the first frame 1311 to rotate with the connection between the first frame 1311 and the first support unit 11 as the rotation axis. It is convenient to adjust the first frame 1311 according to the width of the battery box 40. The two first frames 1311 may be arranged at intervals on both sides of the first support unit 11 along the first direction. One end of the second frame 1312 may be fixedly connected to one end of the first frame 1311 away from the hull assembly 20, and the other end may extend in a direction away from the hull assembly 20, and may be tilted toward the direction close to the other first guide module 131 while extending. The first rolling body 1313 may be movably connected to one end of the second frame 1312 away from the hull assembly 20. In this way, when the hoisting assembly 30 lowers the battery box 40, it is possible to prevent the battery box 40 from contacting the first frame 1311 and the second frame 1312 to cause a collision, thereby affecting the installation of the battery box 40. Figure 3 As shown, during the descent of the battery box 40, the two first rolling bodies 1313 can be respectively brought into contact with the left and right sides of the battery box 40 for guidance, so that the battery box 40 and the first rolling bodies 1313 form rolling friction, which can effectively reduce the wear when contacting the left and right sides of the battery box 40. By adjusting the angle of the first frame 1311, the first guide module 131 can adapt to different types of battery replacement boxes 40, thereby improving the adaptability and flexibility of the battery replacement system.

[0053] E may be the distance between the two first rolling elements 1313 along the first direction, B may be the size of the first bottom bracket unit 11 along the first direction, and E may be greater than or equal to B. Figure 3As shown, the driving unit can drive the two first guide modules 131 to gradually retract to the left and right sides of the battery box 40 and respectively abut against the two first rolling bodies 1313, thereby controlling the shaking of the battery box 40 relative to the width direction of the hull assembly 20 during the descent process. F can be the distance between the first rolling body 1313 away from one end of the hull assembly 20 and the first bottom bracket unit 11 along the height direction of the battery box 40, and D can be the distance between the first guide unit 12 away from one end of the hull assembly 20 and the first bottom bracket unit 11 along the height direction of the battery box 40, and F can be greater than D. In this way, during the descent of the battery box 40, after the battery box 40 abuts against the first rolling body 1313, the first guide module 131 can first control the shaking of the battery box 40 relative to the width direction of the hull assembly 20, and the battery box 40 continues to descend. Under the action of the first guide module 131 controlling the shaking of the battery box 40 relative to the width direction of the hull assembly 20, if the battery box 40 is still affected by the shaking of the hull assembly 20, the first guide unit 12 can further guide the battery box 40 to slide on the inclined surface of the first guide unit 12, and move the battery box 40 to the vertical projection range of the first bottom bracket unit 11 and the battery box 40 abuts against the first bottom bracket unit 11, thereby completing the hoisting of the battery box 40. If the first guide module 131 controls the shaking of the battery box 40 relative to the width direction of the hull assembly 20 so that the battery box 40 is not offset, the hoisting of the battery box 40 can be directly completed.

[0054] like Figure 3 As shown, the first state may also include the hoisting assembly 30 gradually retracting the two first frames 1311 to the left and right sides of the battery box 40 during the descent of the battery box 40, respectively abutting against the two first rolling bodies 1313, so that the two first rolling bodies 1313 can control the shaking of the battery box 40 relative to the width direction of the hull assembly 20 during the descent.

[0055] In some embodiments, G may be the distance between the first rolling body 1313 and the first guide unit 12 along the height direction of the battery box 40, and H may be the height dimension of the battery box 40. G may be less than or equal to H, so that when the two first rolling bodies 1313 abut against the battery box 40 during the descent of the battery box 40, the battery box 40 may abut against the inclined surface of the first guide unit 12 at the same time, and the shaking relative to the width direction of the hull assembly 20 may be controlled by the first guide module 131, and the first guide unit 12 may further guide the battery box 40 to slide on the inclined surface of the first guide unit 12, and move the battery box 40 to the vertical projection range of the first bottom bracket unit 11 and the battery box 40 abuts against the first bottom bracket unit 11, which may improve the hoisting efficiency of the battery box 40, thereby completing the hoisting of the battery box 40.

[0056] In some embodiments, the second guide unit 13 may further include two second guide modules 132. The second guide module 132 may include a third frame 1321, a fourth frame 1322, and a second rolling body 1323. Since the hull assembly 20 also shakes in the length direction of the hull assembly 20, it is convenient to abut the second guide module 132 with the battery box 40 in this way, and effectively control the shaking of the battery box 40 relative to the length direction of the hull assembly 20. One end of the third frame 1321 can be movably connected to the first bottom bracket unit 11, and the other end can extend in a direction away from the hull assembly 20. The driving part can be connected to the third frame 1321 by driving, and the third frame 1321 can be driven to rotate with the connection between the third frame 1321 and the first bottom bracket unit 11 as the rotation axis, so as to rotate the third frame 1321 to the correct angle according to the width of the battery box 40. The two third frames 1321 can be arranged at intervals on both sides of the first bottom bracket unit 11 along the second direction. The angle between the second direction and the length direction of the hull assembly 20 is within the second setting range (0° to 5°). One end of the fourth frame 1322 can be fixedly connected to the end of the third frame 1321 away from the hull assembly 20, and the other end can extend in a direction away from the hull assembly 20, and can be tilted in a direction close to another second guide module 132 while extending. The second rolling body 1323 can be movably connected to the end of the fourth frame 1322 away from the hull assembly 20. In this way, when the hoisting assembly 30 lowers the battery box 40, it can be avoided that the battery box 40 contacts the third frame 1321 and the fourth frame 1322 to cause a collision, thereby affecting the installation of the battery box 40. During the lowering process of the battery box 40, the two second rolling bodies 1323 can be respectively abutted against the battery box 40 for guidance, so that the battery box 40 and the second rolling bodies 1323 form rolling friction, and the rolling friction can effectively reduce the wear when abutting against the battery box 40. Thereby, the battery box 40 can be stably abutted against the two second guide modules 132. By adjusting the angle of the third frame 1321, the second guide module 132 can adapt to different types of battery replacement battery boxes 40, thereby improving the adaptability and flexibility of the battery replacement system.

[0057] like Fig.10 As shown, I can be the distance between the two second rolling bodies 1323 along the second direction, J can be the size of the first bottom bracket unit 11 along the second direction, and I can be greater than or equal to J. In order to facilitate the battery box 40 to descend, the two third frames 1321 have enough distance to allow the third frame 1321 to rotate at a suitable angle with the connection between the third frame 1321 and the first bottom bracket unit 11 as the rotation axis until the battery box 40 descends to abut against the second rolling body 1323. Fig. 9As shown, K can be the distance between the second rolling body 1323 and the first bottom bracket unit 11 along the height direction of the battery box 40, and D can be the distance between the end of the first guide unit 12 away from the hull assembly 20 and the first bottom bracket unit 11 along the height direction of the battery box 40, and K can be greater than D. In this way, during the descent of the battery box 40, after the battery box 40 abuts against the second rolling body 1323, the first guide module 131 and the second guide module 132 can first control the shaking relative to the width direction and the length direction of the hull assembly 20, and the battery box 40 continues to descend. Under the effect of controlling the shaking of the battery box 40 relative to the width direction and the length direction of the hull assembly 20, if the battery box 40 is still affected by the shaking of the hull assembly 20 in the width direction and the length direction, the first guide unit 12 can further guide the battery box 40 to slide on the inclined surface of the first guide unit 12, and move the battery box 40 to the vertical projection range of the first bottom bracket unit 11 and the battery box 40 abuts against the first bottom bracket unit 11, thereby completing the hoisting of the battery box 40. If the first guiding module 131 and the second guiding module 132 control the shaking of the battery box 40 relative to the width direction and the length direction of the hull assembly 20 so that the battery box 40 is not offset, the lifting of the battery box 40 can be completed directly.

[0058] The first state may also include the two third frames 1321 gradually closing when the hoisting assembly 30 lowers the battery box 40 to abut against the second rolling body 1323. This facilitates the first guide module 131 and the second guide module 132 to abut against the battery box 40 together, effectively controlling the shaking of the battery box 40 relative to the width direction and the length direction of the hull assembly 20, and improving the hoisting efficiency of the battery box 40, thereby completing the hoisting of the battery box 40.

[0059] In some embodiments, M may be the distance between the second rolling body 1323 and the first guide unit 12 along the height direction of the battery box 40, and H may be the height dimension of the battery box 40. M may be less than or equal to H. Figure 3 As shown, in this way, when the battery box 40 descends to abut against the first guide unit 12, the left and right sides of the battery box 40 are still abutted against the second guide unit 13, and the first guide unit 12 and the second guide unit 13 can guide the battery box 40 at the same time, which is conducive to better controlling the shaking of the battery box 40 relative to the hull assembly 20 and making the battery box 40 correctly hoisted to the corresponding position of the hull assembly 20, which can improve the hoisting efficiency of the battery box 40 and thereby improve the operating efficiency of the ship.

[0060] In some embodiments, the ship power exchange system may include four first guide units 12, two first guide units 12 may be arranged at intervals on both sides of the first bottom bracket unit 11 along the second direction, and the other two first guide units 12 may be arranged at intervals on both sides of the first bottom bracket unit 11 along the first direction. The interval arrangement can make the first guide unit 12 easy to repair and replace. In this way, the first guide unit 12 can help reduce the offset of the battery box 40 in the width direction and the length direction of the hull component 20. The first guide unit 12 may include a first guide portion 121 and a first locking portion 122, one end of the first locking portion 122 may be detachably connected to the first bottom bracket unit 11, and the other end may extend in a direction away from the hull component 20. It is convenient for the installation, disassembly and replacement of the first locking portion 122. One end of the first guide portion 121 may be fixedly connected to one end of the first locking portion 122 away from the hull component 20, and the other end may extend in a direction away from the hull component 20. When the battery box 40 abuts against the first guide unit 12, both the first guide portion 121 and the first locking portion 122 can guide the battery box 40. Improve the efficiency of hoisting the battery box 40. The angle between the second direction and the length direction of the hull assembly 20 can be within the second setting range (0° to 5°). The spacing between the outer sides of the two first guide portions 121 spaced apart along the second direction can be gradually reduced from the first locking portion 122 to the first guide portion 121. The spacing between the outer sides of the two first guide portions 121 spaced apart along the first direction can be gradually reduced from the first locking portion 122 to the first guide portion 121. In this way, it is convenient to form an inclined surface on the outer side of the first guide portion 121. After the partial inclined surface of the first guide portion 121 guides the battery box 40 to the correct position, the battery box 40 can be locked by further adjusting the shaking of the battery box 40 relative to the length direction and width direction of the hull assembly 20 through the first locking portion 122.

[0061] In other embodiments, the ship power exchange system may further include two first guide units 12, and the two first guide units 12 may be spaced apart along the second direction on both sides of the first bottom bracket unit 11, so as to better guide the battery box 40, so that the shaking of the battery box 40 in the length direction relative to the hull assembly 20 has the least effect on the hoisting. The first guide unit 12 may also include two second guide parts 123, the height of the second guide part 123 may be lower than the height of the first guide part 121, and the second guide part 123 may be detachably connected to the first bottom bracket unit 11 for easy installation. The area of ​​the second guide part 123 in the horizontal direction may gradually decrease from the hull assembly 20 to the first bottom bracket unit 11, so as to facilitate the second guide part 123 to partially form an inclined surface, so that the battery box 40 can be further guided during the hoisting process of the battery box 40.

[0062] In some embodiments, Figure 4As shown, the hull assembly 20 may include a hull unit 21, a second bottom support unit 22, and a ship crane unit 23. The hull unit 21 may include a hull portion 211, a movable seat 212, a battery compartment 213, and a hatch. Since the ship is in a humid water environment, exposed batteries are easily damaged. Closing the hatch of the battery compartment 213 can dehumidify the battery box 40 and prevent the battery box 40 from being damaged. The battery compartment 213 can be detachably connected to the hull portion 211, which is convenient for quick installation and maintenance of the battery compartment 213. The second bottom support unit 22 can be detachably connected to the hull portion 211. It is convenient for the second bottom support unit 22 to be installed and separately disassembled for maintenance. The second bottom support unit 22 can be set in the space surrounded by the battery compartment 213 for the installation position of the battery box 40. The bases 221 of multiple second bottom support units 22 can be arranged at intervals to facilitate heat dissipation of the installed battery box 40. The movable seat 212 can be movably connected to the hull portion 211, so that the movable seat 212 can move the battery box 40 to the correct position. As shown Figure 5 As shown, the mobile seat 212 can be spaced apart from the battery compartment 213. This prevents the mobile seat 212 from colliding with the hatch when it moves. The battery compartment 213 can be provided with an opening on the side close to the mobile seat 212. The hatch can be slidably connected to the opening side of the battery compartment 213. This facilitates the battery box 40 already located on the mobile seat 212 to be quickly moved through the hatch as needed. Closing the hatch can dehumidify the battery box 40 and then form a seal.

[0063] The ship power exchange system may include two fixed components 10. The first base support unit 11 may be detachably connected to the movable seat 212. This facilitates the installation and separate maintenance of the first base support unit 11. The two first base support units 11 may be spaced apart. Conveniently, there is sufficient distance between the two battery boxes 40 installed to the two first base support units 11 for heat dissipation. The distance between the two first base support units 11 may be greater than the distance between adjacent second base support units 22. One end of the first guide module 131 is movably connected to the first base support unit 11, and the first guide module 131 requires space to move for guidance. The second base support unit 22 and the first base support unit 11 are both fixed to the hull assembly 20, and the two are relatively fixed. The second base support unit 22 does not require a guide module for guidance. The distance between the two first base support units 11 may be greater than the distance between adjacent second base support units 22, and the ship space can be reasonably designed and utilized.

[0064] The ship crane unit 23 may include a large vehicle guide rail 231, a large vehicle body 232, a trolley guide rail 233, a telescopic rail 234, a trolley body 235, a first hoisting portion 236, and a first grabbing portion 237. The large vehicle guide rail 231 may be detachably connected to the side of the battery compartment 213 away from the hull assembly 20. The large vehicle body 232 may be slidably connected to the large vehicle guide rail 231. The large vehicle body 232 may maintain a stable trajectory during movement to reduce deviation and shaking. The trolley guide rail 233 may be detachably connected to the large vehicle body 232. The telescopic rail 234 may be slidably connected to the trolley guide rail 233. It is convenient for the telescopic rail 234 to move on the trolley guide rail 233. The telescopic rail 234 may be telescopic along the width direction of the hull assembly 20. The trolley body 235 may be slidably connected to the telescopic rail 234, and the trolley body 235 may move along the length direction of the hull assembly 20. The first hoisting part 236 can be drivably connected to the trolley 235. The trolley 235 can drive the first hoisting part 236 to move along the height direction of the battery box 40. The first grabbing part 237 can be movably connected to the first hoisting part 236. After the first hoisting part 236 is lowered to abut against the top surface of the battery box 40, the first grabbing part 237 grabs the battery box 40.

[0065] The power exchange system may include a third state and a fourth state. The third state may include the ship crane unit 23 being telescoped to the space surrounded by the battery compartment 213, and the hatch moving to the first position. When the hatch moves to the first position, the battery compartment 213, the hatch, and the hull assembly 20 surround and form an enclosed space (that is, the hatch is in a closed state at this time). The fourth state may include the hatch moving to the second position, and the telescopic track 234 telescopes through the hatch to move to the side of the battery compartment 213 close to the movable seat 212. At this time, the hatch is in an open state, and it is convenient to move the battery box 40 into the hatch later. The movable seat 212 moves to the right side of the opening of the battery compartment 213 where the battery box 40 in the first base unit 11 is located. The telescopic rail 234 extends from the opening of the battery compartment 213 to the top of the battery box 40 in the first bottom bracket unit 11, and then the trolley body 235 moves to the top of the battery box 40 in the first bottom bracket unit 11, and drives the first hoisting part 236 to descend to abut against the battery box 40 in the first bottom bracket unit 11, so that the first grabbing part 237 grabs the battery box 40 in the first bottom bracket unit 11, and then drives the first hoisting part 236 to rise until the bottom surface of the battery box 40 is higher than the top of the fixing assembly 10, and then moves to the top of the second bottom bracket unit 22 and descends to abut against the second bottom bracket unit 22, completing the movement of the battery box 40. Again, the telescopic rail 234 can be retracted until the telescopic rail 234 is completely located in the space surrounded by the battery compartment 213, and the hatch is controlled to move to the first position, so that the battery compartment 213, the hatch, and the hull assembly 20 surround and form a closed space.

[0066] In some embodiments, Figure 6As shown, the second bottom bracket unit 22 may include a base 221, a third guide portion 222, and a second locking portion 223. The base 221 may be detachably connected to the hull portion 211. This facilitates the installation of the base 221, and the base 221 may be repaired and replaced separately. One end of the second locking portion 223 may be detachably connected to the base 221, and the other end may extend in a direction away from the hull portion 211. One end of the third guide portion 222 may be detachably connected to one end of the second locking portion 223 away from the hull portion 211, and the other end may extend in a direction away from the hull portion 211. The battery box 40 generated by the ship crane unit 23 when hoisting it from the ship to the second bottom bracket unit 22 is less swaying than when hoisting it from the shore to the first bottom bracket unit 11. After the third guide portion 222 guides the battery box 40, the second locking portion 223 is locked to complete the hoisting. The area of ​​the third guide portion 222 along the horizontal direction can be gradually reduced along the direction from the hull assembly 20 to the first bottom bracket unit 11, so that the third guide portion 222 partially forms an inclined surface. In this way, when the battery box 40 is hoisted and lowered to abut against the inclined surface of the third guide portion 222, the battery box 40 can slide on the inclined surface as the battery box 40 is lowered when the battery box 40 is shaken and deflected. In this way, the battery box 40 can be within the vertical projection range of the second bottom bracket unit 22 and the battery box 40 abuts against the second bottom bracket unit 22.

[0067] In other embodiments, the second base unit 22 may further include a socket 224, which may be detachably connected to the base 221, which may be electrically connected to the hull assembly 20, and which may be electrically connected to a power supply interface of the battery box 40, so as to facilitate the battery box 40 to supply power to the hull assembly 20.

[0068] In some embodiments, Figure 7 As shown, the ship battery replacement method may include steps S11 to S14, and each step will be described in detail below.

[0069] Step S11, when the battery replacement instruction is triggered, the hoisting component 30 can move the battery box 40 to the top of the fixing component 10 to facilitate subsequent hoisting work.

[0070] Step S12: When the hoisting assembly 30 moves the battery box 40 to above the fixing assembly 10, the battery box 40 can be lowered to ensure that the battery box 40 is aligned with the fixing assembly 10 during hoisting.

[0071] Step S13: When the battery box 40 is lowered to a set height (which may be a height flush with the first guide module 131 and the second guide module 132), the two first guide modules 131 may be gradually retracted. Figure 3As shown, when the battery box 40 is lowered, the two first guide modules 131 can abut against the left and right sides of the battery box 40. The two first guide modules 131 can guide the battery box 40 later to reduce the shaking of the battery box 40 relative to the hull assembly 20.

[0072] Step S14, when the battery box 40 is in contact with the first base unit 11, the hoisting assembly 30 can complete the battery replacement.

[0073] In some embodiments, in step S13, when the battery box 40 drops to a set height (which may be a height flush with the first guide module 131 and the second guide module 132), the two first guide modules 131 and the two second guide modules 132 may be gradually retracted. The second guide unit 13 may also include two second guide modules 132. One end of the second guide module 132 may be movably connected to the first base unit 11, and the other end may extend in a direction away from the hull assembly 20. The driving unit may be drivably connected to the second guide module 132 to drive the second guide module 132 to rotate with the connection between the second guide module 132 and the first base unit 11 as the rotation axis. To facilitate the driving unit to drive the two second guide modules 132 to rotate, as shown in FIG. Figure 3 As shown, the two second guide modules 132 are gradually retracted until they are respectively abutted against the two sides of the battery box 40 along the second direction. The abutment between the battery box 40 and the second guide modules 132 can effectively suppress the relative shaking and displacement of the battery box 40 and the first bottom bracket unit 11 during the descent of the battery box 40. The hull assembly 20 will shake in the length direction, so the two second guide modules 132 can be spaced apart on both sides of the first bottom bracket unit 11 along the second direction. The angle between the second direction and the length direction of the hull assembly 20 can be within a first set range (such as 0° to 5°), thereby reducing the relative shaking of the battery box 40 and the hull assembly 20 in the length direction of the hull assembly 20. As shown in FIG. Fig.11As shown, N can be the distance between the two second guide modules 132 away from one side of the hull assembly 20 along the second direction, J can be the size of the first bottom bracket unit 11 along the second direction, and N can be greater than or equal to J, so that the driving unit can drive the two second guide modules 132 to gradually retract to the two sides of the battery box 40 along the second direction and respectively abut against the two second guide modules 132, thereby controlling the shaking of the battery box 40 relative to the length direction of the hull assembly 20 during the descent process. P can be the distance between the second guide module 132 away from one end of the hull assembly 20 and the first bottom bracket unit 11 along the height direction of the battery box 40, and D can be the distance between the first guide unit 12 away from one end of the hull assembly 20 and the first bottom bracket unit 11 along the height direction of the battery box 40, and P can be greater than D. In this way, during the descent of the battery box 40, after the battery box 40 abuts against the second guide module 132, the first guide module 131 and the second guide module 132 can be used together to control the shaking relative to the width and length directions of the hull assembly 20. The battery box 40 continues to descend. Under the action of controlling the shaking of the battery box 40 relative to the width and length directions of the hull assembly 20, the first guide unit 12 can further guide the battery box 40 to slide on the inclined surface of the first guide unit 12, and move the battery box 40 to the vertical projection range of the first bottom bracket unit 11 and the battery box 40 abuts against the first bottom bracket unit 11, thereby completing the lifting of the battery box 40. In this way, the battery box 40 can be quickly lifted during the ship's battery replacement process, so that the battery box 40 and the first bottom bracket unit 11 are smoothly installed, which improves the lifting efficiency of the battery box 40 and thus improves the operating efficiency of the ship.

[0074] Those skilled in the art will appreciate that the above-mentioned embodiments are specific examples for implementing the present disclosure, and in actual applications, various changes may be made thereto in form and detail without departing from the spirit and scope of the present disclosure.
