Description

Technical Field

[0001] The utility model relates to the field of ship power exchange, and in particular to a base of a ship battery box for power exchange and a power exchange ship. Background Art

[0002] At present, electric technology has been widely used in the shipping field. Large-capacity container-type power batteries are usually used to power ships to meet the energy needs during navigation. At present, the battery box structure with side-swap power is adopted in the market. It is necessary to set an electrical connection device on the side wall of the cabin or other structure of the ship to achieve electrical connection with the battery box for power supply. Such a setting and the modification of the cabin or other structure may affect the hull structure and strength. Furthermore, when the battery box is installed on the ship, it is placed on the deck to effectively utilize the space of the deck. Corresponding to the position of the electrical connection device on the ship, the electrical connection assembly on the battery box is also installed on the side wall of the battery box for easy docking. Such a structure makes the battery box have a high requirement on the deck length when it is installed on the ship; at the same time, in order to meet the endurance requirements of the ship, the battery box will be designed to be very large, and when the battery box is installed, the electrical connection assembly on the side of the battery pack needs to be accurately positioned with the electrical connection device on the ship to achieve docking, but the huge battery box will affect the field of vision, thereby increasing the difficulty of positioning and docking when the battery box is installed during the power exchange process. Utility Model Content

[0003] The utility model aims to provide a base for a battery box for a ship for battery replacement and a battery replacement ship, and aims to solve the problems in the field of ship battery replacement that the side replacement method needs to be used to modify the hull structure such as the cabin side wall, 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 utility model is achieved by the following technical solutions:

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

[0006] In this scheme, by setting a ship battery box base on the ship, the ship battery box can be dropped from top to bottom onto the ship battery box base to achieve ship bottom replacement. By adopting the ship bottom replacement method, firstly, the ship battery box base and the ship battery box are in a vertical docking relationship during the battery replacement process, and the ship battery box can always be above the ship battery box base to protect the connection mechanism on the ship battery box base and the connection components on the ship battery box; secondly, the bottom replacement method directly installs the ship battery box base on the deck. Compared with the side replacement, there is no need to set the connection mechanism on the hull structure such as the cabin side wall, avoiding changes to the hull structure itself and affecting the hull structure and strength. At the same time, the bottom replacement method has lower requirements for the deck length. Furthermore, a first guiding mechanism is provided at the end corner of the ship battery box base to guide the ship battery box to fall accurately into the ship battery box base during docking without offset or falling off, while ensuring that the connecting mechanism located on the ship battery box base is accurately docked with the corresponding position of the ship battery box; the first guiding mechanism is provided on the outside of each end corner of the main frame of the ship battery box base, and is inclined from top to bottom, to ensure that the ship battery box first contacts with the first guiding mechanism and then is guided by it, and falls into the ship battery box base in the guided direction and angle.

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

[0008] In this solution, by setting the second guide mechanism inside the first guide mechanism, the ship battery box can guide the ship battery box at the same time when docking, thereby improving the reliability and accuracy of the guidance; therefore, under the guidance of the first guide mechanism and the second guide mechanism, the ship battery box can be accurately positioned, and the entire process does not require manual adjustment, thereby improving the efficiency and safety of battery replacement; in addition, by setting 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 docking between the ship battery box with one side of the connecting mechanism and the ship battery box base, thereby facilitating the positioning and reliable docking between the connecting mechanism and the connecting assembly. Furthermore, not setting the third guide mechanism on the side away from the connecting mechanism can avoid over-positioning of the ship battery box, and secondly, the side away from the connecting mechanism has lower positioning requirements because no electrical connection is required.

[0009] Furthermore, the ship battery box base also includes a buffer assembly, and a plurality of the buffer assemblies are spaced apart on both sides of the main frame along the length direction or the width direction of the battery pack.

[0010] In this solution, the ship battery box uses a buffer component to reduce the pressure on the ship battery box base when docking, providing a certain buffering effect; in order to provide the ship with sufficient electrical energy for endurance, the ship battery box is large in size and heavy in weight, so the ship battery box will produce a certain impact force on the ship battery box base when falling. By arranging a buffer component at the ship battery box base, the fall of the ship battery box can be slowed down, avoiding a hard collision with the ship battery box base to damage the ship battery box and the ship battery box base, thereby affecting the life; since the buffer components are located on both sides of the main frame and are arranged at equal intervals, the impact force on the ship battery box base is not only reduced by the buffer components, but also can be distributed more evenly to the main frame, avoiding cracks or damage to the main frame during one or more battery changes.

[0011] Preferably, the main frame includes two cross beams arranged 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, the two ends of the two cross beams are respectively connected to the two longitudinal beams, and the plurality of buffer components are respectively and spaced apart on the two cross beams; preferably, the buffer component includes a sleeve and an elastic member, the sleeve is fixed on the cross beam, and the elastic member is arranged in the sleeve and is higher than the sleeve in the vertical direction.

[0012] In this solution, the main frame of the ship battery box base is formed by cross beams and longitudinal beams, so that the structure of the ship battery box base is simple and stable, maintaining the bearing capacity of the ship battery box while reducing costs; in addition, the structure of the two cross beams can make the buffer components evenly laid on the cross beams; in addition, the elastic member is limited by the sleeve to ensure that each buffer component acts on the ship battery box at its corresponding position; further, the elastic member is set to be higher than the sleeve so that the bottom of the ship battery box contacts the elastic member first during the falling process, and the elastic member acts on the ship battery box to avoid the ship battery box from causing impact on the ship battery box base when it finally falls on the sleeve.

[0013] Preferably, the first guide mechanism includes a limiting portion and a guiding portion located above the limiting portion, the limiting portion includes a first connecting member and a second connecting member connected to each other, the first connecting member and the second connecting member both extend in a vertical direction and are respectively connected to two adjacent side walls at the end of the longitudinal beam or the cross beam, the guiding portion includes a first guiding surface connected to the top of the first connecting member and a second guiding surface connected to the top of the second connecting member, the first guiding surface and the second guiding surface are both inclined and gradually move away from the longitudinal beam or the cross beam from bottom to top in the horizontal direction.

[0014] In the present 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 then falls into the limiting portion of the first guide mechanism under the guidance of the guiding portion and is 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 displacement due to shaking, thereby affecting the reliability between the connecting mechanism and the connecting components, and even affecting the power supply of the ship battery box to the ship. Furthermore, the limiting part 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, respectively, so that the first guiding 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, thereby improving the reliability of the limiting and avoiding the ship battery box from shifting in one direction; the guiding part also includes a first guiding surface and a second guiding surface, which increase the guiding area of ​​the first guiding mechanism, thereby increasing the landing range of the ship battery box, and even if the landing position is slightly offset, it can be correctly positioned through the guidance of the first guiding surface and the second guiding surface.

[0015] Furthermore, the third guide mechanism is arranged on the side wall of the longitudinal beam or the cross 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 moves away from the longitudinal beam or the cross beam from bottom to top.

[0016] In this solution, since the third guide mechanism is located relative to the first guide mechanism and close to the connecting mechanism, a third guide surface is provided on the third guide mechanism, and the third guide surface is provided opposite 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 can be guided from the outside and the inside in the same direction respectively, so that the alignment of the ship battery box on the side close to the connecting mechanism with the ship battery box base can be more accurate.

[0017] Preferably, the second guide mechanism is located on the upward side wall of the longitudinal beam or the transverse beam and is configured to be conical, with a cross section gradually decreasing from bottom to top.

[0018] In this solution, 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.

[0019] Preferably, the base of the battery box for ships used 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 arranged above the water connecting mechanism; and / or; the connecting mechanism includes an electric connecting mechanism arranged upward and capable of being raised and lowered relative to the main frame, and a second waterproof component is arranged above the electric connecting mechanism.

[0020] In this solution, the connecting mechanism includes a water connecting mechanism and an electrical connecting mechanism, and a waterproof mechanism is also provided on the connecting mechanism; due to the influence of sea waves during the ship power replacement process, the connecting mechanism needs to be waterproofed, especially the electrical connecting mechanism; the water connecting mechanism and the electrical connecting mechanism are protected respectively by the first waterproof component and the second waterproof component to avoid erosion by rain and sea waves.

[0021] Further, the first waterproof component includes a first waterproof door, which is movably arranged along the length direction or width direction of the water connection mechanism; and / or, the second waterproof component includes a second waterproof door, which is movably arranged along the length direction or width direction of the electrical connection mechanism, and the second waterproof door is provided with a protruding piece for cooperating with the third waterproof door on the ship battery box to drive the third waterproof door to open and close synchronously during the opening and closing process of the second waterproof door.

[0022] In this solution, a first waterproof door and a second waterproof door are provided on the water connection mechanism and the electrical connection 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 exchanging power, the first waterproof door and the second waterproof door remain closed. When the ship is exchanging power, the first waterproof door and the second waterproof door are opened to allow the connection mechanism to dock with the ship's battery box. In addition, a protruding piece is provided on the second waterproof door to drive the third waterproof door to open and close synchronously, so that no manual intervention is required during the opening and closing of the waterproof door, thereby improving the automation, reliability and safety of ship power exchange; at the same time, it can also avoid that the electrical connection mechanism on the ship or the electrical connection component on the ship's battery box is exposed for too long due to the asynchronous opening or closing process of the second waterproof door and the third waterproof door, and is interfered and eroded by dust, rainwater, etc., and the power exchange time is long, which affects the power exchange efficiency.

[0023] Furthermore, the second waterproof component also includes a first guide unit and a first sensing element. The first guide unit is arranged on both sides of the electrical connection mechanism along the length direction or the width direction of the electrical connection mechanism. The first guide unit is connected to the second waterproof door to guide the movement of the second waterproof door. The first sensing element is respectively arranged at both ends of the first guide unit along the moving direction of the second waterproof door and corresponds to the opening limit position or the closing limit position respectively. The second waterproof door is provided with a first sensor on one side along its moving direction, so that the first sensor controls the second waterproof door to stop moving after sensing the first sensing element.

[0024] In this solution, the movement of the second waterproof door is guided by the first guide unit, so that the second waterproof door can slide back and forth along a predetermined route to improve the movement efficiency and reliability of the second waterproof door; through the first sensing element provided at both ends of the first guide unit, when the first sensor that moves with the second waterproof door senses the first sensing element, it is confirmed that the second waterproof door has moved to the open extreme position or the closed extreme position, and then the driving component is controlled to stop moving, so that the second waterproof door no longer moves, which can play a role in safety protection for the second waterproof door.

[0025] Further, the ship battery box 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 to the corresponding open position and the closed position; the second waterproof component also includes a limit component, the limit component includes a second sensor, a floating member and a second sensing member, there are two second sensors, two second sensors are arranged at intervals on one side of the second waterproof door along the moving direction of the second waterproof door, the floating member is connected to the second waterproof door and can float between the two second sensors, and the floating member is connected to the driving component through a connecting plate to drive the second waterproof door to move under the drive of the driving component, there are two second sensing members, which are spaced corresponding to the second sensors and are arranged on the side wall of the floating member, when the third waterproof door contacts one of the limit blocks, the third waterproof door no longer moves, and the second waterproof door correspondingly no longer moves, and the floating member continues to move with the driving component to drive the second sensing member to move toward the second sensor on the corresponding side until it is sensed by the second sensor to control the driving component to stop driving.

[0026] In this solution, by setting a limit block on the ship battery box to limit the opening position and closing position of the third waterproof door and the second waterproof door, the position when synchronously opened or closed is determined, so as to avoid the third waterproof door not opening properly when opening and failing to realize the electrical connection between the electrical connection mechanism and the electrical connection component of the ship battery box, and the third waterproof door sliding excessively when closing and affecting the protection of the electrical connection component. The floating member is installed at the side end of the second waterproof door in a floating connection manner. During the process of the driving assembly driving the ship end waterproof door to slide through the connecting plate and the floating member, when the second waterproof door is restricted by the limit block 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. At this time, it indicates that the second waterproof door has completed the opening or closing action, so as to avoid the driving assembly continuing to drive and causing the second waterproof door to move excessively and cause damage. At the same time, on the basis of the first sensor and the first sensing member, the second sensor and the second sensing member are set to achieve double guarantee, so that the control of the driving assembly is more reliable, and the safety and reliability of the second and third waterproof doors are improved, thereby ensuring the safety and reliability of the ship power replacement process.

[0027] Preferably, the end of the protruding piece away from the second waterproof door is set to be conical or have an inclined surface, and its cross-sectional area gradually increases from the end away from the second waterproof door to the end close to the second waterproof door to guide the protruding piece to extend into the matching piece of the third waterproof door to achieve matching; the matching piece is an open groove structure or a hole structure.

[0028] The protruding piece in the present solution is provided with a conical or inclined structure, so as to facilitate guiding the protruding piece to cooperate with the matching piece to achieve linkage.

[0029] Preferably, at least one end of the second waterproof door along its moving direction is provided with a folded edge, and the folded edge extends from an edge of the second waterproof door in a direction away from the electrical connection mechanism.

[0030] In this solution, a folding edge is provided at the second waterproof door, the purpose is 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 tilted, the accumulated water on the second waterproof door can flow out along the two sides of the folding edge, preventing 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 its surrounding structures during movement, thereby affecting the life of the electrical connection mechanism.

[0031] Furthermore, the electrical connection mechanism includes an electrical connection head and a sealing ring, the sealing ring is installed on the circumference of the electrical connection head and its upper end surface is higher than the electrical connection head, the sealing ring has a certain elastic deformation ability and is not lower than the second waterproof door setting in an undeformed state; the folded edge guides the upper end surface of the sealing ring to abut against the lower end surface of the second waterproof door when the second waterproof door is closed.

[0032] In this solution, the sealing of the electrical connector is achieved by fitting the sealing ring and the second waterproof door. Since the sealing ring has elastic deformation capability 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 face of the sealing ring to abut against the lower end face of the second waterproof door when the second waterproof door is closed, the electrical connection mechanism is well sealed.

[0057] like Figure 1 and Figure 2As shown, this embodiment provides a ship battery box base 100, including a main frame 1, a connecting mechanism 2 and a first guide mechanism 4; the main frame 1 is placed horizontally on the ship, and is used to carry and cooperate with the ship battery box 200, so that it can 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 arranged upward to dock with the connecting component 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: firstly removing the depleted battery box, that is, the connecting mechanism 2 on the ship battery box base 100 moves down and disconnects the connection component of the depleted ship battery box 200, and then the depleted ship battery box 200 is transported away from the ship battery box base 100; then installing the fully charged ship battery box 200, that is, the fully charged 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 and connected with the connection component of the ship battery box 200 to complete the battery replacement. Therefore, by setting the ship battery box base 100 on the ship, the ship battery box 200 can fall from the top to the ship battery box base 100 to realize the bottom replacement of the ship. The bottom replacement method of the ship is adopted. First, during the battery replacement process, the ship battery box base 100 and the ship battery box 200 are in a vertical docking relationship. The ship battery box 200 can always be above the ship battery box base 100 to protect the connection mechanism 2 on the ship battery box base 100 and the connection components on the ship battery box 200. Secondly, the bottom replacement method directly installs the ship battery box base 100 on the deck. Compared with the side replacement, there is no need to set the connection mechanism on the hull structure such as the cabin side wall, which avoids changing the structure of the hull itself and affecting the hull structure and strength. At the same time, the bottom replacement method has a lower requirement for the deck length. Further, the ship battery box base 100 is provided with a first guide mechanism 4 to guide the ship battery box 200 to accurately fall into the ship battery box base 100 when docking without offset and falling off, and at the same time ensure that the connection mechanism 2 located on the ship battery box base 100 is accurately docked with the corresponding position of the ship battery box 200.

[0058] In some preferred embodiments, the first guide mechanism 4 is arranged on the outside of 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, ensuring that the ship battery box 200 first contacts the first guide mechanism 4 and is guided by it, and falls into the ship battery box base 100 in the guided direction and angle.

[0059] like Figure 2As shown, the main frame 1 is also provided with a second guide mechanism 5, which is arranged at each end corner of the main frame 1 corresponding to the first guide mechanism 4 and is located on the inner side of 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 when the ship battery box 200 falls on the ship battery box base 100, the second guide mechanism 5 is extended into the matching structure to achieve matching, and plays a further guiding role. That is, the first guide mechanism 4 and the second guide mechanism 5 can cooperate with each other 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 on the ship battery box base 100. In addition, the second guide mechanism 5 cooperates with the matching structure after the ship battery box 200 falls on the ship battery box base 100, and can also play a role in limiting the ship battery box 200.

[0060] In some embodiments, Figure 2 and Figure 3a As shown, the connecting mechanism 2 is arranged at one end of the main frame 1 along the length direction of the ship battery box 200, and a third guide mechanism 6 is provided on the main frame 1; the third guide mechanism 6 is arranged on the end corner of the main frame 1 close to one end of the connecting mechanism 2, and the third guide mechanism 6 is arranged on the side of the second guide mechanism 5 away from the first guide mechanism 4 along the length direction of the ship battery box 200.

[0061] It should be pointed out that the third guiding mechanism 6 is only arranged at one end of the connecting mechanism 2 on the main 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 in the length direction respectively, so that the ship battery box 200 close to the connecting mechanism 2 can be more accurately aligned with the ship battery box base 100, thereby ensuring reliable positioning and docking between the connecting mechanism 2 and the connecting component.

[0062] In other embodiments, the third guide mechanism 6 can also be arranged on the side of the second guide mechanism 5 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 in the width direction respectively, so that the ship battery box 200 on the side close to the connecting mechanism 2 can be more accurately aligned with the ship battery box base 100.

[0063] 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 portion 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, a first-level rough guiding positioning is first performed through the first guide mechanism 4 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.

[0064] 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 primary 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 secondary 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 precise positioning.

[0065] 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 arranged on the main frame 1 in any form, such as only on one side of the main frame 1, unevenly on the main frame, etc., as long as it meets the buffering effect on the ship battery box 200; because 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.

[0066] See again Figure 2The main frame 1 in this embodiment includes: a crossbeam 11 and a longitudinal beam 12, which are used to carry and install other components and provide support for the ship battery box 200; in this embodiment, the two crossbeams 11 are arranged parallel to the length direction of the ship battery box 200, and the two longitudinal beams 12 are arranged perpendicular to the length direction of the ship battery box 200. The two ends of the two crossbeams 11 are respectively connected to the two longitudinal beams 12, and the plurality of buffer components 7 are respectively arranged on the two crossbeams 11 at intervals; the first guide mechanism 4 is installed on the crossbeams 11 or the longitudinal beams 12 at the four corners of the main frame 1. The main frame 1 of the ship battery box base 100 is formed by the crossbeams 11 and the longitudinal beams 12, so that the ship battery box base 100 has a simple and stable structure, and the cost is reduced while maintaining the carrying capacity of the ship battery box 200; in addition, the buffer components 7 can be evenly laid on the crossbeams 11 through the structure of the two crossbeams 11.

[0067] like Figure 3a As shown, the buffer assembly includes a sleeve 71 and an elastic member 72. The sleeve 71 is fixed on the crossbeam 11. 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 to ensure that each buffer assembly 7 acts on the ship battery box 200 at its corresponding position; secondly, the elastic member 72 is set higher than the sleeve 71 so that the bottom of the ship battery box 200 first contacts the elastic member 72 during the falling process, and the elastic member 72 acts on the ship battery box 200 to prevent the ship battery box 200 from causing an impact on the ship battery box base 100 when it finally falls on the sleeve 71.

[0068] In some preferred embodiments, see Figure 3a and Figure 3bThe first guide mechanism 4 includes a limiting portion 41 and a guiding 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 are both extended in the vertical direction and are respectively connected to two adjacent side walls at the end of the longitudinal beam 12 or the cross beam 11. The guiding portion 42 includes a first guiding surface 421 connected to the top of the first connecting member 411 and a second guiding surface 422 connected to the top of the second connecting member. The first guiding surface 421 and the second guiding surface 422 are both inclined and gradually move away from the longitudinal beam 12 or the cross beam 11 from bottom to top in the horizontal direction. When the ship battery box 200 is placed, it first falls on the guiding portion 42, and then slides and falls on the limiting portion 41 under the guidance of the guiding 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 deviation 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, respectively, so that the first guide mechanism 4 is fixed at the end corner of the main frame 1, and can limit the two directions of each end corner of the ship battery box 200, thereby improving the reliability of the limitation and avoiding the ship battery box 200 from shifting in one direction; the guiding portion 42 also includes a first guiding surface 421 and a second guiding surface 422, which increases the guiding area of ​​the first guiding mechanism 4, thereby increasing the landing range of the ship battery box 200, and even if the landing position is slightly offset, it can be correctly positioned through the guidance of the first guiding surface 421 and the second guiding surface 422.

[0069] In some preferred embodiments, Figure 3aAs shown, the third guide mechanism 6 is arranged on the side wall of the longitudinal beam 12 or the cross beam 11; the third guide mechanism 6 can be connected to the side wall of the longitudinal beam 12 or the cross 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 arranged opposite to the first guide surface 421 or the second guide surface 422 and gradually moves away from the longitudinal beam 12 or the cross beam 11 from bottom to top. Since the third guide mechanism 6 is close to the connecting mechanism 2 side relative to the first guide mechanism 4, by arranging the third guide surface 61 on the third guide mechanism 6, and the third guide surface 61 is arranged opposite to one of the first guide surface 421 and the second guide surface 422, the end angle of the ship battery box 200 close to the connecting mechanism 2 can be guided from the outside and the inside in the same direction respectively, so that the alignment of the ship battery box 200 close to the connecting mechanism 2 side to the ship battery box base 100 can be more accurate.

[0070] It should be pointed out that the third guide surface 61 shown in the figure is a slope 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 that the third guide surface 61 gradually moves away from the longitudinal beam 12 or the cross beam 11 from bottom to top.

[0071] In some preferred embodiments, the second guide mechanism 5 is located on the upward side wall of the longitudinal beam 12 or the cross beam 11 and is configured to be conical, and the cross section gradually decreases from bottom to top. The second guide mechanism 5 is in the shape of a cone, and a corresponding matching structure is provided on the ship battery box 200, so that they can better match each other to guide the ship battery box 200 to fall into the preset position on the ship battery box base 100; since 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 to be in the shape of a lock tongue, and the lock tongue is oriented vertically upward. The matching of the lock tongue and the matching structure can improve the limiting effect on the ship battery box 200.

[0072] In some preferred embodiments, see Figure 1 and Figure 4The ship battery box base 100 also includes a waterproof mechanism 3, which is arranged on the connection mechanism 2; the waterproof mechanism 3 includes a first waterproof component 31 and a second waterproof component 32; the connection mechanism 2 includes a water connection mechanism 21 and an electric connection mechanism 22 which are arranged upward and can be lifted and lowered relative to the main frame 1, a first waterproof component 31 is arranged above the water connection mechanism 21, and a second waterproof component 32 is arranged above the electric connection mechanism 22; the first waterproof component 31 and the second waterproof component 32 are opened and closed on the main frame 1. Due to the influence of sea waves during the ship power replacement process, the connection mechanism 2 needs to be waterproofed, especially the electric connection mechanism 22; the first waterproof component 31 and the second waterproof component 32 protect the water connection mechanism 21 and the electric connection mechanism 22 respectively, so as to avoid erosion by rain and sea waves.

[0073] It should be pointed out that the waterproof mechanism 3 may only include the first waterproof component 31 or the second waterproof component 32, and the connecting mechanism 2 may only include the water connecting mechanism 21 or the electrical connecting mechanism 22; correspondingly, when the connecting mechanism 2 includes the water connecting mechanism 21, the waterproof mechanism 3 at least includes the first waterproof component 31; when the connecting mechanism 2 includes the electrical connecting mechanism 22, the waterproof mechanism 3 at least includes the second waterproof component 32.

[0074] In some preferred embodiments, see Figure 5 The first waterproof assembly 31 includes a first waterproof door 311, which is movably arranged along the length direction or width direction of the water connection mechanism 21; the second waterproof assembly 32 includes a second waterproof door 321, which is movably arranged along the length direction or width direction of the electrical connection mechanism 22; the second waterproof door 321 is provided with a protruding piece 3211, which is arranged at the top of the second waterproof door 321, and is used to synchronously open the third waterproof door at the ship battery box 200 when the second waterproof door 321 moves, so that the electrical connection mechanism 22 and the ship battery box 200 are docked. The waterproof function is achieved by controlling the opening and closing of the first waterproof door 311 and the second waterproof door 321. When the ship is not exchanging power, the first waterproof door 311 and the second waterproof door 321 remain closed. When the ship is exchanging power, the first waterproof door 311 and the second waterproof door 321 are opened to allow the connection mechanism 2 to dock with the ship battery box 200. In addition, the protruding piece 3211 on the second waterproof door 321 can drive the synchronous opening and closing of the third waterproof door, so that no human intervention is required in the opening and closing process of the waterproof door, thereby improving the degree of automation, reliability and safety of ship power replacement; at the same time, it can also avoid the electrical connection mechanism 22 on the ship or the electrical connection mechanism 22 on the ship battery box 200 being exposed for too long due to the asynchronous opening or closing process of the second waterproof door 321 and the third waterproof door, thereby being disturbed and eroded by dust, rainwater, etc., and resulting in a long power replacement time, thereby affecting the power replacement efficiency.

[0075] 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 the 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 opening limit position or the closing 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, the second waterproof door 321 is controlled 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 to improve the movement efficiency and reliability of the second waterproof door 321; through the first sensing element 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 element 3241, it is confirmed that the second waterproof door 321 has moved to the open extreme position or the closed extreme 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 role in safety protection of the second waterproof door 321.

[0076] 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 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 can float between the two second sensors 3245. The floating member 3244 is connected to the driving assembly 33 through a connecting plate 3246 to drive the second waterproof door 321 to move under the drive of the driving assembly 33. There are two second sensing members 3243, which are arranged at intervals corresponding to the second sensors 3245 and connected to the side wall of the floating member 3244 through the connecting plate 3246. Specifically, the second sensing member 3243 and the floating member 3244 are respectively located on two opposite surfaces of the connecting plate 3246. In other embodiments, the second sensing member 3243 can also be directly arranged on the floating member 3244.

[0077] Therefore, when the third waterproof door contacts one of the limit blocks, the third waterproof door does not move anymore, and the second waterproof door 321 does not move anymore accordingly, and the floating member 3244 continues to move with the driving assembly 33 to drive the second sensing member 3243 to move toward the second sensor 3245 on the corresponding side until the second sensor 3245 senses and controls the driving assembly 33 to stop driving. By setting the limit blocks on the ship battery box 200 to limit the opening position and the closing position of the third waterproof door and the second waterproof door 321, the positions when synchronously opened or synchronously closed are determined, so as to avoid the third waterproof door not opening properly when opening and the inability to realize the electrical connection between the electrical connection mechanism 22 and the electrical connection mechanism 22 of the ship battery box 200, and the third waterproof door sliding excessively when closing and affecting the protection of the electrical connection mechanism 22. The floating member 3244 is installed at the side end of the second waterproof door 321 in a floating connection manner. During the process of the driving assembly 33 driving the ship end waterproof door to slide through the connecting plate 3246 and the floating member 3244, when the second waterproof door 321 is restricted by the limiting block 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, so as to avoid the driving assembly 33 continuing to drive and causing the second waterproof door 321 to move excessively and cause damage. At the same time, on the basis of the first sensor 3242 and the first sensing member 3241, the second sensor 3245 and the second sensing member 3243 can be set to achieve double guarantee, so that the control of the driving assembly 33 is more reliable, and the safety and reliability of the second and third waterproof doors are improved, thereby ensuring the safety and reliability of the ship's power replacement process.

[0078] Preferably, the end of the protruding piece away from the second waterproof door 321 is set to be conical or have an inclined surface, and its 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 protruding piece to extend into the matching piece of the third waterproof door to achieve matching; the matching piece is an open groove structure or a hole structure.

[0079] In some preferred embodiments, the end of the protruding member 3211 away from the second waterproof door 321 is set to be conical or have an inclined surface, and its 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 protruding member 3211 to extend into the matching member of the third waterproof door at the bottom of the ship battery box 200 to achieve matching; the matching member is an open groove structure or a hole structure. It should be understood that the matching structure at the protruding member 3211 and the third waterproof door is only preferred, and any structure that can realize the second waterproof door 321 driving the third waterproof door to open and close synchronously can be used as an embodiment of the present application.

[0080] It should be pointed out that although the present specification adopts the method of providing a protruding piece 3211 on the second waterproof door 321 so that the second waterproof door 321 and the third waterproof door are opened synchronously, it should be understood that the protruding piece 3211 can also be provided at the third waterproof door, and a structure that cooperates with the protruding piece 3211, such as an open groove or a hole structure, can be provided on the second waterproof door 321.

[0081] In some embodiments, Figure 6 As shown, at least one end of the second waterproof door 321 along its moving direction is provided with a folded edge 3212, and the folded edge 3212 extends from the edge of the second waterproof door 321 in a direction away from the electrical connection mechanism 22. The provision of the folded edge 3212 improves the strength of the second waterproof door 321 and enhances the waterproof effect of the second waterproof door 321; when the ship battery box 200 is tilted, the accumulated water on the second waterproof door 321 can flow out along the two sides of the folded edge 3212, thereby preventing rainwater from entering the electrical connection mechanism 22 inside the second waterproof door 321. At the same time, the second waterproof door 321 can also avoid interference with the electrical connection mechanism 22 and its surrounding structures during movement, thereby affecting the life of the electrical connection mechanism 22.

[0082] like Figure 6 , Figure 7 and Figure 8 As shown, the ship battery box base 100 includes an electrical connector and a sealing ring 221 installed on the circumference of the electrical connector in the electrical connection mechanism 22. The sealing ring 221 has a certain elastic deformation ability. In the undeformed state, the upper end surface of the sealing ring 221 is not lower than the electrical connector 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 against the lower end surface of the waterproof door 321 when the waterproof door 321 is closed, so that the electrical connector is well sealed. Figure 8 The sealing ring 221 is fixed on the ship battery box base 100 through a connecting seat 222. The sealing ring 221 includes an annular O-ring 223 and an open sealing ring 224 arranged on the annular O-ring 223. The annular O-ring 223 and the sealing ring 224 have elastic deformation capabilities.

[0083] In some preferred embodiments, see Figure 6 and Figure 7The second waterproof assembly 32 also includes a second mounting plate 322 and a first accordion cover 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 its moving direction and the second mounting plate 322 on the corresponding side are provided with first accordion covers 325 covering the top of the first guide unit 323, and the first accordion covers 325 at both ends of the second waterproof door 321 can be extended and retracted 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 accordion cover 325 is correspondingly installed between the two mounting plates 310 to cover the entire first guide unit 323 (slide rail) to isolate it from the external environment, so that the first guide unit 323 is not affected by the humid environment, does not cause rust and other problems, and improves the service life of the second guide unit 324.

[0084] In some preferred embodiments, see Figure 7 The second waterproof component 32 also includes a protective shell 327, a horizontal groove 328 and a second accordion cover 326. The driving component 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 opened on the upper surface of the ship battery box base 100 so that the connecting plate 3246 can be inserted therein and connected between the driving component 33 and the floating member 3244. The protective shell 327 is arranged on one side of the second waterproof door 321 and covers the upper part of the limit assembly, and the two ends are connected to the second accordion cover 326 covering the upper part of the horizontal groove 328. 26 is connected, and the second accordion covers 326 at both ends of the protective shell 327 can be extended and retracted with the movement of the protective shell 327 so that the horizontal groove 328 is always covered during the movement with the second waterproof door 321, and the second accordion covers 326 can be used to prevent dust and rain; the protective shell 327 is provided to isolate the limit assembly from the external environment, and the second accordion cover 326 is provided to isolate the horizontal groove 328 from the external environment, which can play a role in isolating and protecting the electrical components in the ship battery box base 100, avoiding problems such as moisture and rust that affect the service life.

[0085] Based on the same inventive concept, the embodiment of this specification also provides a battery-swap ship, including the ship battery box base 100 described in any of the aforementioned embodiments, such as Figure 6 As shown, the battery-swapping ship adopts the bottom battery-swapping mode. After the ship battery box 200 is docked and matched with the ship battery box base 100, the second waterproof door 321 is opened, and at the same time, the third waterproof door at one end of the ship battery box 200 is opened, and the connecting mechanism 2 extends upward and automatically docks with the bottom of the ship battery box 200. There is no need for manual assistance by sailors, which is particularly suitable for use in rainy weather conditions.
