Description

Technical Field

[0001] The present invention relates to the field of ship battery replacement, and in particular to a base of a ship battery box for battery replacement and a battery replacement ship. Background Art

[0002] Electric power technology is now widely used in the shipping industry, often using large-capacity containerized power batteries to power ships and meet energy needs during navigation. The battery box structure currently used on the market for side-mounted battery swapping requires electrical connectors to be installed on the side walls of the ship's cabins or other structures to achieve electrical connection with the battery box for power supply. This installation, coupled with modifications to the cabins or other structures, may affect the ship's hull structure and strength. Furthermore, when installed on a ship, the battery box is placed on the deck to efficiently utilize deck space. Corresponding to the location of the electrical connectors on the ship, the electrical connector components on the battery box are also mounted on the side walls of the battery box for easy docking. This structure imposes a high deck length requirement for installation. Furthermore, to meet the ship's endurance requirements, the battery box is designed to be large. During installation, the electrical connector components on the battery pack's side must be precisely aligned with the ship's electrical connectors for docking. However, the large battery box obstructs visibility, further complicating positioning and docking during the battery swap process. Summary of the Invention

[0003] The purpose of the present invention is to provide a base for a battery box for ships for battery replacement and a battery replacement ship, and to solve the problems in the field of ship battery replacement that the side replacement method requires the modification of the cabin side wall and other hull structures, which affects the hull structure and strength, has high requirements on the deck length, and the ship battery box is difficult to position and dock when installed on the ship.

[0004] The purpose of the present invention is achieved by the following technical solutions:

[0005] The present invention provides a base for a battery box for a ship used for battery replacement, which is arranged on a ship to support the battery box. The base comprises: a main frame, a connecting mechanism and a first guide mechanism. The connecting mechanism is arranged on the main frame and is arranged upward to dock with the connecting assembly on the battery box. The first guide mechanism is arranged outside each end corner of the main frame and is inclined from top to bottom to guide the battery box to be placed on the main frame.

[0006] In the scheme, the ship battery box can be placed on the ship battery box base from top to bottom to realize the ship bottom replacement by setting the ship battery box base on the ship. The ship bottom replacement is adopted. Firstly, the ship battery box base and the ship battery box are in the upper and lower docking relationship during the battery replacement process, and the ship battery box can always be above the ship battery box base to protect the connecting mechanism on the ship battery box base and the connecting component on the ship battery box. Secondly, the bottom replacement method directly installs the ship battery box base on the deck, which does not need to set the connecting mechanism on the hull structure such as the cabin side wall, avoiding the change of the ship body structure to affect the ship structure and strength. At the same time, the bottom replacement method has lower requirements for the length of the deck. Further, the first guide mechanism is arranged at the end angle of the ship battery box base to guide the ship battery box to accurately fall into the ship battery box base during docking without deviation and falling off, and to ensure that the connecting mechanism on the ship battery box base and the corresponding position of the ship battery box are accurately docked. The first guide mechanism is arranged outside each end angle of the main frame of the ship battery box base, and is arranged obliquely from top to bottom to ensure that the ship battery box is first contacted with the first guide mechanism and then guided by the first guide mechanism, and falls into the ship battery box base in the guided direction and angle.

[0007] Preferably, the ship battery box base further comprises a second guide mechanism, the second guide mechanism is arranged at each end angle of the main frame and located inside the first guide mechanism corresponding to the first guide mechanism; preferably, the connecting mechanism is installed at one end of the main frame along the length direction of the ship battery box; the ship battery box base further comprises a third guide mechanism arranged at the end angle of the main frame close to the one end of the connecting mechanism, and the third guide mechanism is arranged on the side away from the first guide mechanism of the second guide mechanism along the length direction or the width direction of the ship battery box.

[0008] In the scheme, the second guide mechanism is arranged inside the first guide mechanism, so that the ship battery box can be guided at the same time during docking, improving the reliability and accuracy of the guidance. Therefore, the accurate positioning of the ship battery box can be realized under the guidance of the first guide mechanism and the second guide mechanism, and the whole process does not need manual adjustment, thereby improving the battery replacement efficiency and safety. In addition, by arranging the third guide mechanism on the side close to the connecting mechanism, the third guide mechanism cooperates with the first guide mechanism to guide the ship battery box from both sides, further improving the accuracy of the docking of the ship battery box with the ship battery box base on the side with the connecting mechanism, so as to facilitate the positioning and reliable docking between the connecting mechanism and the connecting component. Further, the third guide mechanism is not arranged on the side away from the connecting mechanism, which is to avoid over-positioning of the ship battery box, and the side away from the connecting mechanism has lower positioning requirements because it does not need electrical connection.

[0009] Further, the ship battery box base further comprises a buffer assembly, a plurality of buffer assemblies are arranged at intervals on both sides of the main frame along the length direction or the width direction of the battery pack; preferably, the main frame comprises two cross beams arranged in parallel to the length direction of the ship battery box and two longitudinal beams arranged perpendicular to the length direction of the ship battery box, both ends of the two cross beams are connected with the two longitudinal beams respectively, and a plurality of buffer assemblies are arranged at intervals on the two cross beams respectively; preferably, the buffer assembly comprises a sleeve and an elastic piece, the sleeve is fixed on the cross beam, and the elastic piece is arranged in the sleeve and is higher than the sleeve in the vertical direction.

[0010] In this scheme, the ship battery box reduces the pressure on the ship battery box base through the buffer assembly when docking, providing a certain buffering effect; in order to provide enough electric energy for the ship to continue to travel, the ship battery box is large in size and heavy in quality, so that the ship battery box will generate a certain impact force on the ship battery box base when falling, and the buffer component arranged on the ship battery box base can slow down the falling of the ship battery box, avoid hard collision with the ship battery box base, and cause damage to the ship battery box and the ship battery box base, affecting the service life; since the buffer assembly is arranged at both sides of the main frame and is arranged at equal intervals, the impact force received by the ship battery box base is not only reduced by the buffer assembly, but also can be more evenly distributed to the main frame, avoiding cracks or damage to the main frame in one or more battery replacement; further, the cross beams and longitudinal beams form the main frame of the ship battery box base, so that the ship battery box base is simple and stable in structure, maintains the carrying capacity of the ship battery box, and reduces the cost; in addition, the structure of the two cross beams can evenly lay the buffer assembly on the cross beam; in addition, the sleeve limits the elastic piece, ensuring that each buffer assembly acts on the ship battery box at the corresponding position; further, arranging the elastic piece higher than the sleeve makes the bottom of the ship battery box contact the elastic piece first during the falling process, and the elastic piece acts on the ship battery box to avoid the impact on the ship battery box base when the ship battery box finally falls on the sleeve.

[0011] Preferably, the first guide mechanism comprises a limiting part and a guide part above the limiting part, the limiting part comprises a first connecting piece and a second connecting piece connected to each other, the first connecting piece and the second connecting piece both extend along the vertical direction and are connected to two adjacent side walls of the end of the longitudinal beam or the transverse beam respectively, the guide part comprises a first guide surface connected above the first connecting piece and a second guide surface connected above the second connecting piece, the first guide surface and the second guide surface are both arranged obliquely and gradually away from the longitudinal beam or the transverse beam from bottom to top in the horizontal direction; preferably, the third guide mechanism is arranged on the side wall of the longitudinal beam or the transverse beam and has a third guide surface facing the second guide mechanism, the third guide surface is arranged opposite to the first guide surface or the second guide surface and gradually away from the longitudinal beam or the transverse beam from bottom to top; preferably, the second guide mechanism is arranged on the upward side wall of the longitudinal beam or the transverse beam and is tapered, the cross section gradually decreases from bottom to top.

[0012] In this solution, the first guide mechanism specifically includes a limiting portion and a guiding portion, and the guiding portion is arranged above the limiting portion in the vertical direction; when the ship battery box is in place, the bottom first contacts the guiding portion of the first guide mechanism, and after being guided by the guiding portion, it falls into the limiting portion of the first guide mechanism and is also limited by the limiting portion. Since the ship battery replacement environment is often on board a ship and is greatly affected by wind and waves, the limiting portion can effectively prevent the ship battery box from shaking after being placed on the ship battery box base, so that the ship can remain stably placed on the ship battery box base even during navigation, avoiding deviation due to shaking and thus affecting the reliability between the connecting mechanism and the connecting assembly, and even affecting the power supply of the ship battery box to the ship; further, the limiting portion also includes a first connecting member and a second connecting member, which extend in the vertical direction and are fixed to two adjacent side walls at the end of the longitudinal beam or the transverse beam, so that the first guide mechanism is fixed at the end corner of the main frame, which can limit the two directions of each end corner of the ship battery box, improve the reliability of the limit, and avoid the ship battery box in one direction. upward offset; the guide portion also includes a first guide surface and a second guide surface, which increases the guiding area of ​​the first guide mechanism, so that the landing range of the ship battery box is increased, and even if the landing position is slightly offset, it can be correctly positioned by the guidance of the first guide surface and the second guide surface; further, since the third guide mechanism is close to the connecting mechanism side relative to the first guide mechanism, by providing a third guide surface on the third guide mechanism, and the third guide surface is arranged relative to one of the first guide surface and the second guide surface, the end angle of the ship battery box close to the connecting mechanism side can be guided from the outside and the inside in the same direction respectively, so that the ship battery box on the side close to the connecting mechanism can be more accurately aligned with the ship battery box base; further, the second guide mechanism is conical in shape, and a corresponding matching structure is provided on the ship battery box, so that they can better match each other to guide the ship battery box to fall into the preset position on the ship battery box base; since the cross-section of the second guide mechanism gradually decreases from top to bottom, the ship battery box can be guided by the second guide mechanism in all directions.

[0013] Preferably, the base of the battery box for battery replacement also includes a waterproof mechanism arranged on the connecting mechanism, and the waterproof mechanism includes a first waterproof component and / or a second waterproof component; the connecting mechanism includes a water connecting mechanism arranged upward and capable of being raised and lowered relative to the main frame, and a first waterproof component is provided above the water connecting mechanism; and / or; the connecting mechanism includes an electrical connecting mechanism arranged upward and capable of being raised and lowered relative to the main frame, and a second waterproof component is provided above the electrical connecting mechanism.

[0014] In the scheme, the connecting mechanism includes a water connecting mechanism and an electric connecting mechanism, and a waterproof mechanism is further arranged on the connecting mechanism; during the ship battery replacement process, the connecting mechanism needs to be waterproofed, especially the electric connecting mechanism, due to the influence of sea waves; the first waterproof component and the second waterproof component are arranged to respectively protect the water connecting mechanism and the electric connecting mechanism, so as to avoid the erosion of rain and sea waves.

[0015] Further, the first waterproof component includes a first waterproof door movably arranged along the length direction or the width direction of the water connecting mechanism; and / or, the second waterproof component includes a second waterproof door movably arranged along the length direction or the width direction of the electric connecting mechanism, and an extension piece is arranged on the second waterproof door to cooperate with a third waterproof door on the ship battery box to drive the third waterproof door to be synchronously opened and closed during the opening and closing of the second waterproof door; preferably, the second waterproof component further includes a first guide unit and a first sensing piece, the first guide unit is arranged on both sides of the electric connecting mechanism along the length direction or the width direction of the electric connecting mechanism, the first guide unit is connected with the second waterproof door to guide the movement of the second waterproof door, and the first sensing piece is arranged at both ends of the first guide unit along the movement direction of the second waterproof door and corresponds to the opening limit position or the closing limit position, respectively; a first sensor is arranged on one side of the second waterproof door along the movement direction of the second waterproof door, so that the first sensor controls the second waterproof door to stop moving after sensing the first sensing piece.

[0016] In the scheme, the first waterproof door and the second waterproof door are arranged on the water connecting mechanism and the electric connecting mechanism, and the waterproof function is realized by controlling the opening and closing of the first waterproof door and the second waterproof door; when the ship is not replaced, the first waterproof door and the second waterproof door are kept in the closed state, and when the ship is replaced, the first waterproof door and the second waterproof door are opened to make the connecting mechanism dock with the ship battery box. In addition, the extension piece arranged on the second waterproof door can drive the third waterproof door to be synchronously opened and closed, so that manual intervention is not needed during the opening and closing of the waterproof door, and the automation degree, reliability and safety of the ship battery replacement are improved; meanwhile, the second waterproof door and the third waterproof door can be prevented from being out of synchronization during the opening and closing process, so that one of the electric connecting mechanism on the ship or the electric connecting component on the ship battery box is not exposed for too long time to be interfered and eroded by dust, rain and the like, and the replacement time is not too long to affect the replacement efficiency; preferably, the first guide unit is arranged to guide the movement of the second waterproof door, so that the second waterproof door can slide back and forth along the predetermined route to improve the movement efficiency and reliability of the second waterproof door; when the first sensor moving with the second waterproof door senses the first sensing piece, it is confirmed that the second waterproof door moves to the opening limit position or the closing limit position, and then the driving component is controlled to stop moving, so that the second waterproof door does not move any more, which can play a safety protection role on the second waterproof door.

[0017] Further, the ship battery box is provided with two limiting blocks corresponding to the opening and closing positions, respectively, for limiting the third waterproof door from moving after being driven by the second waterproof door to the corresponding opening and closing positions; the second waterproof assembly further comprises a limiting assembly, the limiting assembly comprising a second sensor, a floating member and a second sensing member, the second sensor having two, the two second sensors being arranged on one side of the second waterproof door along the moving direction of the second waterproof door, the floating member being connected with the second waterproof door and being floatable between the two second sensors, and the floating member being connected with the driving assembly through a connecting plate to drive the second waterproof door to move under the driving of the driving assembly, the second sensing member having two, being arranged on the side wall of the floating member and corresponding to the second sensors, when the third waterproof door contacts one of the limiting blocks, the third waterproof door stops moving, the second waterproof door also stops moving, and the floating member continues to move with the driving assembly to drive the second sensing member to move to the corresponding second sensor until the second sensor senses and controls the driving assembly to stop driving.

[0018] In the scheme, the limiting blocks are arranged on the ship battery box to limit the opening and closing positions of the third waterproof door and the second waterproof door, so that the positions when the third waterproof door and the second waterproof door are opened or closed are determined, avoiding the third waterproof door from being unable to achieve electrical connection between the electrical connection mechanism and the electrical connection assembly of the ship battery box due to opening failure, and avoiding the third waterproof door from affecting the protection of the electrical connection assembly due to excessive sliding when closing. The floating member is installed on the side end of the second waterproof door in a floating connection manner, and the driving assembly drives the second waterproof door to slide through the connecting plate and the floating member. When the second waterproof door is limited by the limiting blocks and no longer moves, one of the second sensors senses the corresponding second sensing member on the same side, and the driving assembly stops moving, indicating that the second waterproof door has completed the opening or closing action, avoiding the driving assembly from continuing to drive and causing the second waterproof door to move excessively and be damaged. Meanwhile, based on the first sensor and the first sensing member, the second sensor and the second sensing member are arranged to achieve double guarantee, making the control of the driving assembly more reliable and improving the safety and reliability of the second and third waterproof doors, thereby ensuring the safety and reliability during the ship battery replacement process.

[0020] The protruding piece in the scheme is tapered or has a slope, which facilitates guiding the protruding piece to match with the matching piece to achieve linkage; further, the folded edge is arranged at the second waterproof door, which aims to improve the strength of the second waterproof door and enhance the waterproof effect of the second waterproof door; when the ship battery box is inclined, the water accumulated on the second waterproof door can flow out along the two sides of the folded edge, avoiding rainwater from entering the electrical connection mechanism inside the second waterproof door. At the same time, the second waterproof door can also avoid interference with the electrical connection mechanism and the surrounding structure during movement, thereby affecting the service life of the electrical connection mechanism.

[0021] Further, the electrical connection mechanism includes an electrical connection head and a sealing ring, the sealing ring is installed around the electrical connection head and the upper end surface thereof is higher than the electrical connection head, the sealing ring has a certain elastic deformation capacity and is not lower than the second waterproof door in the undeformed state; the folded edge guides the upper end surface of the sealing ring to abut on the lower end surface of the second waterproof door when the second waterproof door is closed.

[0022] In the scheme, the sealing ring and the second waterproof door are attached to achieve sealing of the electrical connection head. Since the sealing ring has elastic deformation capacity and is not lower than the second waterproof door when not in contact with the second waterproof door, and the folded edge guides the upper end surface of the sealing ring to abut on the lower end surface of the second waterproof door when the second waterproof door is closed, the electrical connection mechanism is well sealed.

At the same time, the bottom replacement method has lower requirements on the deck length.

[0026] Second, the present invention can keep the ship battery box stable and accurately positioned; the ship battery box has a certain inertia during the descent process, and the ship battery box base provided by the present invention is provided with a buffer spring. When the container-type ship battery box is released to fall freely at a certain height, the bottom is first pressed on the buffer spring, and then falls to the upper surface of the ship battery box base after buffering, which can reduce the impact of the box feet on the ship battery box and reduce the impact noise; the ship battery box base provided by the present invention is provided with a first guide mechanism, a second guide mechanism and a third guide mechanism. Through the guiding action of the above-mentioned guide mechanisms, the ship battery box is accurately placed in the predetermined position, and by limiting it, the displacement and overturning of the ship battery box under strong wind and wave conditions are prevented.

[0047] As Figure 1 and Figure 2As shown, the embodiment provides a ship battery box base 100, which comprises a main frame 1, a connecting mechanism 2 and a first guide mechanism 4; the main frame 1 is horizontally placed on the ship for bearing and cooperating with the ship battery box 200 to complete the battery replacement process on the ship battery box base 100; the connecting mechanism 2 and the first guide mechanism 4 are installed on the main frame 1, wherein the connecting mechanism 2 is upwardly arranged for docking with the connecting assembly at the bottom of the ship battery box 200; the first guide mechanism 4 is used to guide the ship battery box 200 to fall into the main frame 1 when the ship battery box 200 is installed on the ship. The specific battery replacement process includes: first, the discharged battery box is unloaded, that is, the connecting mechanism 2 on the ship battery box base 100 is lowered to disconnect with the connecting assembly of the discharged ship battery box 200, and then the discharged ship battery box 200 is carried away from the ship battery box base 100; and then, the full battery ship battery box 200 is installed, that is, the full battery ship battery box 200 is positioned on the main frame 1 through the guidance of the first guide mechanism 4, and then the connecting mechanism 2 of the ship battery box base 100 is lifted to connect with the connecting assembly of the ship battery box 200, thereby completing the battery replacement work. Thus, by arranging the ship battery box base 100 on the ship, the ship battery box 200 can fall from top to bottom on the ship battery box base 100 to realize the bottom replacement of the ship. By using the bottom replacement mode, firstly, the ship battery box base 100 and the ship battery box 200 are in an upper and lower docking relationship during the battery replacement process, and the ship battery box 200 can always be above the ship battery box base 100 to protect the connecting mechanism 2 on the ship battery box base 100 and the connecting assembly on the ship battery box 200; secondly, the bottom replacement mode can directly install the ship battery box base 100 on the deck, and compared with the side replacement mode, the connecting mechanism does not need to be arranged on the hull structure such as the cabin side wall, thereby avoiding the change of the ship body structure to affect the ship structure and strength, and at the same time, the bottom replacement mode has lower requirements for the length of the deck. Further, the ship battery box base 100 is provided with the first guide mechanism 4 to guide the ship battery box 200 to accurately fall into the ship battery box base 100 during docking without deviation and falling off, and to ensure that the connecting mechanism 2 on the ship battery box base 100 and the corresponding position of the ship battery box 200 are accurately docked.

[0048] In some preferred embodiments, the first guide mechanism 4 is arranged outside each end corner of the main frame 1 and is inclined from top to bottom to guide the ship battery box 200 to be placed on the main frame 1, so as to ensure that the ship battery box 200 is first contacted with the first guide mechanism 4 and then guided to fall into the ship battery box base 100 in the guided direction and angle.

[0049] As Figure 2As shown, the main body frame 1 is also provided with a second guide mechanism 5, which is arranged at each end corner of the main body frame 1 and located inside the first guide mechanism 4. The ship battery box 200 is provided with a corresponding matching structure, such as a groove, a positioning hole, etc., so that the second guide mechanism 5 can be matched by extending into the matching structure during the process of the ship battery box 200 falling onto the ship battery box base 100, thereby further guiding. That is, the first guide mechanism 4 and the second guide mechanism 5 can be matched to further improve the reliability and accuracy of guiding the ship battery box 200, thereby ensuring that the ship battery box 200 accurately falls on the preset position of the ship battery box base 100. In addition, the second guide mechanism 5 and the matching structure can also play a role in limiting the ship battery box 200 after the ship battery box 200 falls onto the ship battery box base 100.

[0050] In some embodiments, as shown in Figure 2 and Figure 3a The connecting mechanism 2 is arranged at one end of the main body frame 1 along the length direction of the ship battery box 200, and the main body frame 1 is provided with a third guide mechanism 6. The third guide mechanism 6 is arranged at the end corner of the main body frame 1 close to one end of the connecting mechanism 2, and the third guide mechanism 6 is arranged on the side away from the first guide mechanism 4 along the length direction of the ship battery box 200.

[0051] It should be pointed out that the third guide mechanism 6 is arranged only at one end of the connecting mechanism 2 on the main body frame 1, so that the end corner of the ship battery box 200 close to the connecting mechanism can be guided from the outside and the inside along the length direction, respectively, so that the alignment of the ship battery box 200 close to the connecting mechanism 2 to the ship battery box base 100 can be more accurate, thereby ensuring reliable positioning and docking between the connecting mechanism 2 and the connecting assembly.

[0052] In other embodiments, the third guide mechanism 6 can also be arranged on the side away from the first guide mechanism 4 along the width direction of the ship battery box 200, so that it can be guided from the outside and the inside along the width direction, respectively, so that the alignment of the ship battery box 200 close to the connecting mechanism 2 to the ship battery box base 100 can be more accurate.

[0053] In some preferred embodiments, the first guide mechanism 4 is higher than the second guide mechanism 5 and the third guide mechanism 6 in the vertical direction; since the first guide mechanism 4 is located at the end corner of the main frame 1, when the ship battery box 200 is in place, the contact part of the first guide mechanism 4 is the end corner of the ship battery box 200; therefore, when the ship battery box 200 is in place, the first guide mechanism 4 is first used to perform a first-level rough guiding positioning to ensure that the second guide mechanism 5 enters the matching structure of the ship battery box 200 and ensures that the ship battery box 200 falls into the third guide mechanism; more preferably, the third guide mechanism 6 is higher than the second guide mechanism 5 in the vertical direction, and the second guide mechanism 5 cooperates with the third guide mechanism 6 to achieve precise positioning of the ship battery box 200, reduce the displacement of the ship battery box 200 in the length direction, and ensure the reliability of the docking of the connecting mechanism 2.

[0054] In some preferred embodiments, a first guide mechanism 4 and a second guide mechanism 5 are provided on the left side of the main frame 1, and a first guide mechanism 4, a second guide mechanism 5 and a third guide mechanism 6 are provided on the right side of the main frame 1; when the ship battery box 200 is freely falling at a certain height, the left side of the ship battery box 200 first contacts the first guide mechanism 4 on the left side of the main frame 1 for a first-level rough positioning, and through the guiding action of the first guide mechanism 4 on the left side of the main frame 1, the positioning hole of the left corner of the ship battery box 200 falls into the second guide mechanism 5 on the left side of the main frame 1 for a second-level rough positioning; at the same time, since the left side of the ship battery box 200 is guided by the first guide mechanism 4 on the left side of the main frame 1, the right side of the ship battery box 200 abuts against the first guide mechanism 4 on the right side of the main frame 1, and the ship battery box 200 is guided by the first guide mechanism 4 on the right side of the main frame 1 and falls into the third guide mechanism on the right side of the main frame 1, and finally the positioning hole of the right corner of the ship battery box 200 falls into the second guide mechanism 5 on the right side of the main frame 1, realizing three-level fine positioning.

[0055] like Figure 2 As shown, in this embodiment, a buffer component 7 is provided on the ship battery box base 100; a plurality of the buffer components 7 are arranged at intervals on both sides of the main frame 1 along the length direction or width direction of the ship battery box 200; but it should be understood that the installation position and spacing setting method of the buffer component 7 are only preferred. In other embodiments, the buffer component 7 can be set on the main frame 1 in any form, such as being set only on one side of the main frame 1, being unevenly set on the main frame, etc., as long as it satisfies the buffering effect on the ship battery box 200; since the ship battery box 200 will have a certain impact on the main frame 1 when it is in place, the buffer component 7 is used to reduce the impact force on the main frame 1, reduce the damage to it and increase the service life of the ship battery box base 100.

[0056] See again Figure 2The main frame 1 in the embodiment includes beams 11 and longitudinal beams 12 for bearing and mounting other components and providing support for the ship battery box 200. In the embodiment, two beams 11 are arranged parallel to the length direction of the ship battery box 200, two longitudinal beams 12 are arranged perpendicular to the length direction of the ship battery box 200, the two ends of the two beams 11 are respectively connected to the two longitudinal beams 12, and a plurality of buffer assemblies 7 are respectively arranged on the two beams 11 in a spaced manner. The first guide mechanism 4 is installed on the beam 11 or the longitudinal beam 12 at the four corners of the main frame 1. The beams 11 and the longitudinal beams 12 form the main frame 1 of the ship battery box base 100, so that the ship battery box base 100 has a simple and stable structure, maintains the carrying capacity of the ship battery box 200, and reduces the cost. In addition, the two beams 11 can uniformly lay the buffer assemblies 7 on the beams 11.

[0057] As shown in Figure 3a , the buffer assembly includes a sleeve 71 and an elastic member 72. The sleeve 71 is fixed on the beam 11, and the elastic member 72 is arranged in the sleeve 71 and is higher than the sleeve in the vertical direction. The sleeve 71 limits the elastic member 72, ensuring that each buffer assembly 7 acts on the ship battery box 200 at the corresponding position. Secondly, the elastic member 72 is arranged to be higher than the sleeve 71, so that the bottom of the ship battery box 200 first contacts the elastic member 72 during falling, and the elastic member 72 acts on the ship battery box 200 to avoid the impact on the ship battery box base 100 when the ship battery box 200 finally falls on the sleeve 71.

[0058] In some preferred embodiments, referring to Figure 3a and Figure 3bThe first guide mechanism 4 includes a limiting portion 41 and a guide portion 42 located above the limiting portion 41. The limiting portion 41 includes a first connecting member 411 and a second connecting member 412 connected to each other. The first connecting member 411 and the second connecting member 412 both extend vertically and are connected to two adjacent side walls at the end of the longitudinal beam 12 or the transverse beam 11, respectively. The guide portion 42 includes a first guide surface 421 connected above the first connecting member 411 and a second guide surface 422 connected above the second connecting member. The first guide surface 421 and the second guide surface 422 are both inclined and gradually move away from the longitudinal beam 12 or the transverse beam 11 from bottom to top in the horizontal direction. When the ship battery box 200 is positioned, it first lands on the guide portion 42 and then slides onto the limiting portion 41 under the guidance of the guide portion 42. Since the ship battery replacement environment is often on board a ship and is greatly affected by wind and waves, the limit portion 41 can effectively prevent the ship battery box 200 from shaking after being placed on the ship battery box base 100, so that the ship can remain stably placed on the ship battery box base 100 even during navigation, avoiding offset due to shaking and thus affecting the reliability between the connecting mechanism 2 and the connecting components, and even affecting the power supply of the ship battery box 200 to the ship. Furthermore, the limiting portion 41 also includes a first connecting member 411 and a second connecting member 412, which extend in the vertical direction and are fixed to two adjacent side walls at the end of the longitudinal beam 12 or the transverse beam 11, so that the first guide mechanism 4 is fixed at the end corner of the main frame 1, which can limit the two directions of each end corner of the ship battery box 200, improve the reliability of the limitation, and avoid the ship battery box 200 from shifting in one direction; the guide portion 42 also includes a first guide surface 421 and a second guide surface 422, which increases the guiding area of ​​the first guide mechanism 4, so that the positioning range of the ship battery box 200 is increased, and even if the positioning position is slightly offset, it can be correctly positioned through the guidance of the first guide surface 421 and the second guide surface 422.

[0059] In some preferred embodiments, Figure 3aAs shown, the third guide mechanism 6 is disposed on the sidewall of the longitudinal beam 12 or the transverse beam 11; the third guide mechanism 6 can be connected to the sidewall of the longitudinal beam 12 or transverse beam 11 by welding or bolts, and has a third guide surface 61 facing the second guide mechanism 5; the third guide surface 61 is disposed opposite the first guide surface 421 or the second guide surface 422 and gradually moves away from the longitudinal beam 12 or transverse beam 11 from bottom to top. Because the third guide mechanism 6 is located on the side closer to the connecting mechanism 2 relative to the first guide mechanism 4, by providing the third guide surface 61 on the third guide mechanism 6 and opposing one of the first guide surface 421 and the second guide surface 422, the end corner of the ship battery box 200 on the side closer to the connecting mechanism 2 can be guided from both the outside and inside in the same direction, thereby achieving more precise alignment of the ship battery box 200 on the side closer to the connecting mechanism 2 with the ship battery box base 100.

[0060] It should be pointed out that the third guide surface 61 shown in the figure is a sloped structure, but the shape of the third guide surface 61 in the figure is only preferred. In other embodiments, a smooth curved surface or the like can be used to realize the guiding function of the third guide surface 61, and it is only necessary to ensure that the third guide surface 61 gradually moves away from the longitudinal beam 12 or the cross beam 11 from bottom to top.

[0061] In some preferred embodiments, the second guide mechanism 5 is located on the upward-facing sidewall of the longitudinal beam 12 or transverse beam 11 and is configured in a tapered shape, with a cross-section gradually decreasing from bottom to top. The second guide mechanism 5 is tapered, and a corresponding mating structure is provided on the ship battery box 200, thereby better matching each other to guide the ship battery box 200 to fall into a preset position on the ship battery box base 100. Because the cross-section of the second guide mechanism gradually decreases from top to bottom, the ship battery box 200 can be guided by the second guide mechanism in all directions. Preferably, the second guide mechanism 5 is configured in the shape of a lock tongue, and the lock tongue is oriented vertically upward. The cooperation between the lock tongue and the mating structure can enhance the limiting effect on the ship battery box 200.

[0062] In some preferred embodiments, see Figure 1 and Figure 4The ship battery box base 100 further comprises a waterproof mechanism 3 arranged above the connecting mechanism 2; the waterproof mechanism 3 comprises a first waterproof assembly 31 and a second waterproof assembly 32; the connecting mechanism 2 comprises a water connecting mechanism 21 and an electric connecting mechanism 22 arranged upward and capable of lifting relative to the main body frame 1, the first waterproof assembly 31 is arranged above the water connecting mechanism 21, and the second waterproof assembly 32 is arranged above the electric connecting mechanism 22; the first waterproof assembly 31 and the second waterproof assembly 32 are opened and closed on the main body frame 1. During the ship battery replacement process, the connecting mechanism 2 needs to be waterproofed, especially the electric connecting mechanism 22, due to the influence of sea waves; through the first waterproof assembly 31 and the second waterproof assembly 32, the water connecting mechanism 21 and the electric connecting mechanism 22 are protected respectively, so as to avoid being eroded by rain and sea waves.

[0063] It should be pointed out that the waterproof mechanism 3 can only comprise the first waterproof assembly 31 or the second waterproof assembly 32, and the connecting mechanism 2 can only comprise the water connecting mechanism 21 or the electric connecting mechanism 22; correspondingly, when the connecting mechanism 2 comprises the water connecting mechanism 21, the waterproof mechanism 3 at least comprises the first waterproof assembly 31; when the connecting mechanism 2 comprises the electric connecting mechanism 22, the waterproof mechanism 3 at least comprises the second waterproof assembly 32.

[0064] In some preferred embodiments, referring to Figure 5 The first waterproof assembly 31 comprises a first waterproof door 311 movably arranged along the length direction or the width direction of the water connecting mechanism 21; the second waterproof assembly 32 comprises a second waterproof door 321 movably arranged along the length direction or the width direction of the electric connecting mechanism 22; the second waterproof door 321 is provided with an extension piece 3211 arranged at the top of the second waterproof door 321, for synchronously opening a third waterproof door at the ship battery box 200 when the second waterproof door 321 moves, so as to make the electric connecting mechanism 22 dock with the ship battery box 200. The waterproof function is realized by controlling the opening and closing of the first waterproof door 311 and the second waterproof door 321; when the ship is not replaced, the first waterproof door 311 and the second waterproof door 321 remain in the closed state, and when the ship is replaced, the first waterproof door 311 and the second waterproof door 321 are opened to dock the connecting mechanism 2 with the ship battery box 200. In addition, the extension piece 3211 arranged on the second waterproof door 321 can drive the third waterproof door to open and close synchronously, so that manual intervention is not needed during the opening and closing of the waterproof door, and the automation, reliability and safety of the ship battery replacement are improved; at the same time, it can also avoid that one of the electric connecting mechanism 22 on the ship or the electric connecting mechanism 22 on the ship battery box 200 is exposed for too long time due to the asynchronous opening and closing of the second waterproof door 321 and the third waterproof door, so as to be disturbed and eroded by dust, rain and the like, and the replacement time is too long to affect the replacement efficiency.

[0065] In some preferred embodiments, the second waterproof component 32 also includes a first guide unit 323 and a first sensing element 3241. The first guide unit 323 is arranged on both sides of the electrical connection mechanism 22 along the length direction or width direction of the electrical connection mechanism 22. The first guide unit 323 is connected to the second waterproof door 321 to guide the movement of the second waterproof door 321. The first sensing element 3241 is respectively arranged at both ends of the first guide unit 323 along the moving direction of the second waterproof door 321 and corresponds to the open limit position or the closed limit position respectively. The second waterproof door 321 is provided with a first sensor 3242 on one side along its moving direction, so that after the first sensor 3242 senses the first sensing element 3241, it controls the second waterproof door 321 to stop moving. The movement of the second waterproof door 321 is guided by the first guide unit 323, so that the second waterproof door 321 can slide back and forth along a predetermined route, thereby improving the movement efficiency and reliability of the second waterproof door 321; through the first sensing members 3241 provided at both ends of the first guide unit 323, when the first sensor 3242 that moves with the second waterproof door 321 senses the first sensing member 3241, it is confirmed that the second waterproof door 321 has moved to the open limit position or the closed limit position, and then the driving component 33 is controlled to stop moving, so that the second waterproof door 321 no longer moves, which can play a safety protection role for the second waterproof door 321.

[0066] The ship battery box 200 is provided with two limit blocks corresponding to the open position and the closed position, respectively, for limiting the third waterproof door from moving after being driven by the second waterproof door 321 to the corresponding open position and the closed position; the second waterproof assembly 32 also includes a limit assembly, which includes a second sensor 3245, a floating member 3244 and a second sensing member 3243. There are two second sensors 3245, and the two second sensors 3245 are spaced apart and arranged on one side of the second waterproof door 321 along the moving direction of the second waterproof door 321. The floating member 3244 is connected to the second waterproof door 321 and floats between the two second sensors 3245. The floating member 3244 is connected to the drive assembly 33 via a connecting plate 3246, thereby driving the second waterproof door 321 to move under the drive assembly 33. Two second sensing members 3243 are spaced apart, corresponding to the second sensors 3245. These two members are connected to the sidewalls of the floating member 3244 via connecting plates 3246. Specifically, the second sensing members 3243 and the floating member 3244 are located on opposite sides of the connecting plate 3246. In other embodiments, the second sensing members 3243 may be directly mounted on the floating member 3244.

[0067] Thus, when the third waterproof door contacts one of the limiting blocks, the third waterproof door stops moving, the second waterproof door 321 stops moving accordingly, and the floating member 3244 continues to move with the driving assembly 33 to drive the second sensing member 3243 to move to the corresponding second sensor 3245 until the second sensor 3245 senses and controls the driving assembly 33 to stop driving. By arranging the limiting blocks on the ship battery box 200, the opening and closing positions of the third waterproof door and the second waterproof door 321 are limited, so that the position of the synchronous opening or closing is determined, avoiding the third waterproof door from being unable to achieve electrical connection between the electrical connection mechanism 22 and the electrical connection mechanism 22 of the ship battery box 200 due to the opening of the third waterproof door not being in place, and affecting the protection of the electrical connection mechanism 22 due to the over-sliding of the third waterproof door during closing. The floating member 3244 is installed on the side end of the second waterproof door 321 in a floating connection manner. During the sliding process of the driving assembly 33 through the connecting plate 3246 and the floating member 3244 to drive the ship end waterproof door, when the second waterproof door 321 is limited by the limiting blocks and no longer moves, one of the second sensors 3245 senses the corresponding second sensing member 3243 on the same side, and the driving assembly 33 stops moving. At this time, it indicates that the second waterproof door 321 has completed the opening or closing action, avoiding the driving assembly 33 from continuing to drive and causing the second waterproof door 321 to move excessively and be damaged. At the same time, based on the first sensor 3242 and the first sensing member 3241, the second sensor 3245 and the second sensing member 3243 are arranged to realize double guarantee, so that the control of the driving assembly 33 is more reliable, the safety and reliability of the second and third waterproof doors are improved, and the safety and reliability during the ship battery replacement process are ensured.

[0068] Preferably, the end of the extending member away from the second waterproof door 321 is tapered or has a slope, and the cross-sectional area gradually increases from the end away from the second waterproof door 321 to the end close to the second waterproof door 321 to guide the extending member to extend into the cooperating member of the third waterproof door to realize cooperation. The cooperating member is an open slot structure or a hole structure.

[0069] In some preferred embodiments, the end of the extending member 3211 away from the second waterproof door 321 is tapered or has a slope, and the cross-sectional area gradually increases from the end away from the second waterproof door 321 to the end close to the second waterproof door 321 to guide the extending member 3211 to extend into the cooperating member of the third waterproof door at the bottom of the ship battery box 200 to realize cooperation. It should be understood that the cooperating structure of the extending member 3211 and the third waterproof door is only preferred, and any structure that can realize the synchronous opening and closing of the second waterproof door 321 and the third waterproof door can be used as an embodiment of the present application.

[0070] It should be noted that although the second waterproof door 321 and the third waterproof door are opened synchronously by setting the protruding piece 3211 on the second waterproof door 321 in the present specification, it should be understood that the protruding piece 3211 can also be set on the third waterproof door, and a structure such as an open slot or a hole structure that cooperates with the protruding piece 3211 can be set on the second waterproof door 321.

[0071] In some embodiments, as shown in Figure 6 At least one end of the second waterproof door 321 along its moving direction is provided with a folded edge 3212 extending from the edge of the second waterproof door 321 towards the direction away from the electrical connection mechanism 22. The provision of the folded edge 3212 improves the strength of the second waterproof door 321 while enhancing the waterproof effect of the second waterproof door 321; when the ship battery box 200 is tilted, the water accumulated on the second waterproof door 321 can flow out along the two sides of the folded edge 3212, avoiding rainwater from entering the electrical connection mechanism 22 inside the second waterproof door 321. At the same time, it can also make the second waterproof door 321 avoid interference with the electrical connection mechanism 22 and its surrounding structure during movement and thus affect the service life of the electrical connection mechanism 22.

[0072] As shown in Figure 6 , Figure 7 and Figure 8 The ship battery box base 100 includes an electrical connection head and a sealing ring 221 installed circumferentially on the electrical connection head at the electrical connection mechanism 22, and the sealing ring 221 has a certain elastic deformation capacity. In the undeformed state, the upper end surface of the sealing ring 221 is not lower than the electrical connection head and the second waterproof door 321; the folded edge 3212 is used to guide the upper end surface of the sealing ring 221 to seal and abut on the lower end surface of the waterproof door 321 when the waterproof door 321 is closed, so that the electrical connection head is well sealed. Referring to Figure 8 , the sealing ring 221 is fixed on the ship battery box base 100 through a connecting seat 222, and the sealing ring 221 includes an annular O-ring 223 and a sealing ring 224 in an open shape arranged on the annular O-ring 223, and the annular O-ring 223 and the sealing ring 224 have elastic deformation capacity.

[0073] In some preferred embodiments, referring to Figure 6 and Figure 7The second waterproof assembly 32 further comprises a second mounting plate 322 and a first concertina 325; the mounting plate 322 is arranged at both ends of the first guide unit 323; the edges of both ends of the second waterproof door 321 along the moving direction of the second waterproof door 321 are provided with the first concertina 325 above the first guide unit 323 on the corresponding side of the second mounting plate 322, and the first concertina 325 at both ends of the second waterproof door 321 can be expanded and contracted with the movement of the second waterproof door 321 so that the first guide unit 323 is always covered during the movement of the second waterproof door 321. In this embodiment, the first concertina 325 is arranged between the two mounting plates 310, and the entire first guide unit 323 (slide rail) is covered to isolate it from the external environment, so that the first guide unit 323 is not affected by the humid environment and rusting problems are avoided, thereby prolonging the service life of the second guide unit 324.

[0074] In some preferred embodiments, referring to Figure 7 The second waterproof assembly 32 further comprises a protective shell 327, a horizontal groove 328 and a second concertina 326; the driving assembly 33 for driving the second waterproof door 321 to move is arranged below the upper surface of the ship battery box base 100, the horizontal groove 328 is arranged on the upper surface of the ship battery box base 100 so that the connecting plate 3246 can be arranged in the horizontal groove 328 and connected between the driving assembly 33 and the floating piece 3244, the protective shell 327 is arranged on one side of the second waterproof door 321 and covers the limiting assembly, and the two ends of the protective shell 327 are connected with the second concertina 326 covering the horizontal groove 328, the second concertina 326 at both ends of the protective shell 327 can be expanded and contracted with the movement of the protective shell 327 so that the horizontal groove 328 is always covered during the movement of the second waterproof door 321, and the second concertina 326 can be used for dust and rain prevention; the limiting assembly is isolated from the external environment by arranging the protective shell 327, and the horizontal groove 328 is isolated from the external environment by arranging the second concertina 326, which can play a protective role in isolating the electrical components in the ship battery box base 100 from the external environment, thereby avoiding problems such as rusting caused by moisture and affecting the service life.

[0075] Based on the same inventive concept, the embodiments of the present application also provide a battery replacement ship comprising the ship battery box base 100 described in any one of the preceding embodiments, as shown in Figure 6 The battery replacement ship adopts a bottom battery replacement mode, the second waterproof door 321 is opened after the ship battery box 200 is docked and matched with the ship battery box base 100, and the third waterproof door at one end of the ship battery box 200 is also opened, the connecting mechanism 2 is extended upward and automatically docked with the bottom of the ship battery box 200.
