Description

Technical Field

[0001] The utility model relates to the field of ship battery replacement, and in particular to a waterproof device for a ship battery box and a ship battery box. Background Art

[0002] At present, the replacement of petroleum energy with electricity has expanded from the field of land transportation to the field of maritime transportation. However, since many inland ports lack conditions suitable for the construction of charging pile infrastructure, the solution of replacing batteries has become one of the main technical development directions in the field of electric ships. In order to solve this problem, the current method is to build charging stations at a certain distance from the port to facilitate short-distance delivery of ship battery boxes. The vehicle is responsible for transporting and replacing the ship battery boxes between the charging station and the port terminal.

[0003] Considering that ships need to sail in waters, the demand for high battery endurance becomes very urgent. In order to meet this demand, ships need to carry ultra-large ship battery boxes. In order to achieve rapid replacement of ship battery boxes, they are usually locked on the ship deck and exposed to the outdoor environment. In addition, charging of large ship battery boxes must also be carried out in an outdoor environment. Therefore, external environmental factors may have a significant impact on the safety of ship battery boxes and their charging and discharging processes, and put forward higher requirements for the waterproof performance of ship battery boxes.

[0004] In order to ensure the safe operation of the ship battery box, effective measures need to be taken to improve its waterproof performance. This may include designing a stronger and well-sealed ship battery box casing to resist the impact of harsh weather conditions and water environment on the ship battery box. Utility Model Content

[0005] The utility model aims to provide a waterproof device for a ship battery box and a ship battery box, aiming to solve the problem of sealing and safety of the box end electrode head part of the ship battery box in the field of ship power replacement.

[0006] The purpose of the utility model is achieved by the following technical solutions:

[0007] The utility model provides a waterproof device for a ship battery box in a first aspect, which is arranged on a box body of the ship battery box to protect a box end electrode head located at the bottom of the ship battery box. The waterproof device for the ship battery box comprises a box end waterproof door and a limiting member. The box end waterproof door can be moved along the length direction or width direction of the box end electrode head to open or close the box end electrode head. One end of the limiting member is connected to the box body, and the other end is connected to the box end waterproof door, so that the box end waterproof door remains in a closed state when no external force is applied.

[0008] In this scheme, firstly, the box-end waterproof door is arranged on the bottom of the ship battery box to protect the box-end electrode head located at the bottom of the ship battery box, so that when the battery box is not docked with the ship, the box-end electrode head is always closed to prevent the box-end electrode head from being disturbed by external debris, especially in rainy weather, it can avoid the invasion of rainwater and affect the service life of the box-end electrode head; at the same time, it also avoids safety problems caused by the exposure of the box-end electrode head. Secondly, the box-end electrode head is arranged at the bottom of the ship battery box, which can facilitate the ship battery box to be placed on the ship from top to bottom for bottom-type battery replacement during the battery replacement process. Compared with the existing side battery replacement, the bottom-type battery replacement reduces the occupation of the side space, so that the length requirement of the ship deck is lower. Furthermore, through the limiting effect of the limiting member, the box-end waterproof door is kept closed when it is not subjected to external force, so that the box-end electrode head can be protected when the box-end waterproof door is not subjected to external force, and the box-end waterproof door can be opened when subjected to external force, so that the box-end electrode head can be docked with the ship to achieve battery replacement and provide energy for the ship's navigation.

[0009] Preferably, the box end waterproof door is provided with matching parts at both ends in a direction perpendicular to its moving direction to match with an external mechanism so as to drive the box end waterproof door to move under the drive of the external mechanism.

[0010] In this solution, the box-end waterproof door can be fully automated by setting a matching part. The box-end waterproof door and the box-end waterproof door can be opened and closed synchronously under the drive of an external mechanism. The whole process requires no human intervention, thereby improving the efficiency and safety of battery replacement.

[0011] Furthermore, the box end waterproof door is horizontally arranged and is provided with a folded edge at at least one end along its moving direction, and the folded edge extends from the edge of the box end waterproof door in a direction away from the box end electrode head.

[0012] In this solution, by providing a folded edge at one end of the box end waterproof door in the moving direction, on the one hand, the strength of the box end waterproof door can be increased by the added folded edge; on the other hand, extending the folded edge in the direction away from the box end electrode head can avoid interference or damage to the box end electrical connector and surrounding structures during the opening and closing process of the door.

[0013] Preferably, the box end electrode head is arranged downward and is circumferentially surrounded by a sealing ring, the box end waterproof door is located below the box end electrode head and moves horizontally, the end of the folded edge connected to the box end waterproof door is the highest point, and the other end of the folded edge away from the box end waterproof door is the lowest point, the lowest point is set to be no higher than the lower end surface of the sealing ring, and the highest point is set to be no lower than the lower end surface of the sealing ring.

[0014] In this solution, a sealing ring is arranged around the box end electrode head to ensure that the outer circumference of the box end electrode head is isolated from the external environment; further, by setting the height of the folded edge and the sealing ring, when the box end waterproof door is closed, the lower end face of the sealing ring is squeezed by the box end waterproof door and fits on the box end waterproof door, so that a sealed space is formed at the electrode head, thereby ensuring that the box end electrode head is not affected by rain, seawater and humid environment, and providing the safety and reliability of the box end battery box. At the same time, the lowest point of the folded edge is not higher than the lower end face of the sealing ring, so that the box end waterproof door will not cause damage to the sealing ring during the opening and closing process.

[0015] Furthermore, the waterproof device also includes a guiding mechanism and a limiting block, wherein the guiding mechanism is arranged on both sides of the box end electrode head along the length direction or the width direction of the box end electrode head, and the guiding mechanism is connected to the box end waterproof door to guide the box end waterproof door to move along the length direction or the width direction of the box end electrode head, and the limiting blocks are respectively arranged at both ends of the guiding mechanism along the moving direction of the box end waterproof door so that the box end waterproof door stops moving after contacting the limiting blocks.

[0016] In this scheme, by means of the guide mechanism and the limit block arranged on both sides of the box end electrode head, the box end waterproof door is made to slide back and forth along the guide mechanism to improve the reliability, stability and efficiency of the opening and closing of the box end waterproof door. Furthermore, by means of the limit block provided, the opening position and the closing position of the box end waterproof door are limited, so that the position of the box end waterproof door when it is synchronously opened or synchronously closed is determined, thereby avoiding the box end waterproof door not opening properly when opening and failing to achieve the electrical connection between the electrode head and the ship end electrode head, and the box end waterproof door sliding excessively when closing and affecting the protection of the box end electrode head.

[0017] Preferably, the waterproof device also includes a mounting plate, which is located on the side of the limit block away from the box end electrode head along the moving direction of the box end waterproof door, and the mounting plate is configured to extend downward so that the limit member is connected between the mounting plate and the box end waterproof door in a horizontal direction.

[0018] In this solution, the installation position of the limit block is determined by the position of the installation plate, thereby determining the closing limit of the box end waterproof door. At the same time, the limit piece is connected between the installation plate and the box end waterproof door, so that when the box end waterproof door is not subjected to external force, it is pulled by the installation plate and the limit piece and remains in the preset position, that is, in the closed state.

[0019] Furthermore, the box end waterproof door includes a door body and two fixed brackets, the number of the guide mechanisms is at least two, the upper ends of the two fixed brackets are respectively connected to the two guide mechanisms located on both sides of the box end electrode head, and the lower ends are respectively connected to the two ends of the door body, and the fixed bracket is provided with a first connecting portion for connecting the limit member.

[0020] In this solution, the box end waterproof door is provided as a door body and two fixed brackets to enhance the stability of the box end waterproof door when sliding; when the box end waterproof door is a single track, it may tilt to one side of the guide mechanism when sliding, and by providing at least two guide mechanisms, the box end waterproof door is more stable when the guide mechanism slides. At the same time, by providing the first connecting portion on the fixed bracket, it is convenient to connect the limiter to the fixed bracket.

[0021] Preferably, there are multiple first connecting parts, which are arranged at intervals along the moving direction of the box-end waterproof door, so that the limiting member can be connected to any one of the first connecting parts to adjust the pre-tightening force between the box-end waterproof door and the mounting plate; or, the box-end waterproof door also includes a connecting plate connected to the first connecting part, and the connecting plate is provided with multiple second connecting parts arranged at intervals along the moving direction of the box-end waterproof door, the limiting member is connected to one of the second connecting parts, and the first connecting part is connected to any other one of the second connecting parts to adjust the pre-tightening force between the box-end waterproof door and the mounting plate.

[0022] In the present solution, the adjustment of the preload force between the box end waterproof door and the mounting plate is achieved through the cooperation of multiple first connecting parts or second connecting parts and the limiter; since the limiter can be connected to any first connecting part or second connecting part, the limiter can have different preload forces by connecting the limiter to different first connecting parts or second connecting parts; as time goes by, the limiter may experience fatigue, thereby affecting its preload effect; however, in the solution, the operator can fine-tune the size of the preload force of the limiter by adjusting the connection position, thereby maintaining the stability and overall performance of the waterproof device for the ship battery box.

[0023] Furthermore, the door body is provided with extension parts at both ends along a direction perpendicular to the moving direction of the box end waterproof door, and the extension parts are provided with grooves sunken toward the box end waterproof door to form the matching part.

[0024] In this solution, by arranging matching parts at both ends of the door body, the forces at both ends of the box end waterproof door are balanced when the external mechanism cooperates with the matching parts to drive the box end waterproof door to move, so that it can move smoothly during the opening and closing process, avoiding problems such as uneven opening and closing process caused by uneven force; secondly, the matching part is arranged as a groove, which makes the structure of the matching part simple and easy to manufacture, and also facilitates the external mechanism to cooperate with the groove to act on the box end waterproof door, thereby improving the matching reliability.

[0025] The utility model provides a ship battery box in a second aspect, comprising a box body, a box end electrode head and the aforementioned ship battery box waterproof device, wherein the box end electrode head is arranged at the bottom of the box body, and the ship battery box waterproof device is arranged on the box body corresponding to the box end electrode head to protect the box end electrode head.

[0026] Compared with the prior art, the at least one technical solution adopted in the embodiments of this specification can achieve the following beneficial effects:

[0027] First, the waterproof device provided by the utility model has high protection capability. The box-end waterproof door is used to protect the box-end electrode head, and the limiting part is limited to always remain closed when not subjected to external force. At the same time, the sealing space of the utility model is realized by a sealing ring and an elastic device. When the box-end waterproof door is closed, the sealing ring receives a certain pre-tightening force, which can form a good sealing space, maintain stability in various harsh environments, and has excellent waterproof performance. This design ensures the reliability of the box-end electrical connector, so that the box-end electrical connector can maintain its performance in a dry state in the ship power replacement application scenario; the reliability of the waterproof device is crucial to ensuring the stable operation of the equipment and the safety of personnel.

[0028] Second, compared with the side-swap method, the bottom-swap method provided by the utility model can save deck space; the operating space for bottom-swap is the bottom of the container, which saves deck length space compared to the side-swap method, and can adapt to container freight ships with lower deck height and shorter length; the box-end waterproof door is arranged at the bottom of the battery box and the box-end waterproof door is arranged on the upper surface of the ship-end bracket, so that the battery box and the ship-end bracket are connected up and down, and then during the battery replacement process, the battery box is always above the ship-end bracket, so that the box-end electrode head and the ship-end electrode head can be protected by the battery box body, especially in rainy weather, to avoid the invasion of rain.

[0029] Second, the utility model is highly durable and easy to repair and replace; multiple first connection parts or second connection parts are set on the box end waterproof door so that the connection position of the limiter can be adjusted at any time, which gives the entire system flexibility; this connection method not only simplifies the installation process, but also has the ability to adjust the preload force of the limiter; over time, the limiter may experience fatigue, which affects its preload effect; however, in the utility model, the operator can fine-tune the preload force by adjusting the connection position, thereby maintaining the stability and overall performance of the waterproof device. Even when the limiter is damaged, it can be simply replaced and connected between the box end waterproof door and the mounting plate to achieve the limiting effect on the box end waterproof door.

[0030] Third, the ship battery box provided by the utility model can perform bottom battery replacement on the ship because the box end electrode head and the waterproof device are arranged at the bottom. Compared with the existing side battery replacement, the bottom battery replacement can reduce the occupation of the side space, thereby saving the length space of the deck or having lower requirements for the length space of the deck. Furthermore, in the bottom battery replacement, since the box end electrode head is located at the bottom of the ship battery box, such a position setting is more conducive to avoiding the invasion of rainwater and impurities, and improves safety and reliability, compared with the side battery replacement in which the box end electrode head is located on the side of the ship battery box.

[0044] The purpose of this embodiment is to solve the problem of sealing and safety of the box end electrode head part of the ship battery box in the field of ship battery replacement.

[0045] This embodiment provides a waterproof device for a ship battery box, which is located on the ship battery box and is intended to protect the box end electrode head 21 located at the bottom of the ship battery box. The waterproof device 1 includes a box end waterproof door 11 and a limiter 15; the box end waterproof door 11 can move along the length or width direction of the box end electrode head 21 to open or close the box end electrode head 21. One end of the limiter 15 is connected to the box body of the ship battery box 3, and the other end is connected to the box end waterproof door 11, so that the box end waterproof door 11 can remain closed even without external force.

[0046] like Figure 1 As shown, in this embodiment, the waterproof device 1 can be opened and closed on the ship battery box 3 to protect it, so that when the ship battery box is not docked with the ship, the box end electrode head 21 is always closed to prevent the box end electrode head 21 from being disturbed by external debris, especially in rainy weather, it can avoid the invasion of rainwater and affect the service life of the box end electrode head; at the same time, it also avoids the safety problem caused by the exposure of the box end electrode head 21. In this embodiment, the waterproof device 1 is arranged at the bottom of the ship battery box 3, and the bottom of the ship battery box 3 is provided with a box end electrical connector 2, which can facilitate the ship battery box to be placed on the ship from top to bottom for bottom-type power exchange during the power exchange process. The bottom-type power exchange reduces the occupation of the side space compared to the existing side power exchange, so that the length requirement of the ship deck is lower. In addition, in this embodiment, the box end waterproof door is kept closed when it is not subjected to external force through the limiting effect of the limiting member, so that the box end electrode head can be protected when the box end waterproof door is not subjected to external force, and the box end waterproof door can be opened when subjected to external force, so as to realize that the box end electrode head can be docked with the ship to achieve power exchange and provide energy for the navigation of the ship. Therefore, when it is necessary to dock with the equipment end, the waterproof device 1 moves and opens to expose the box-end electrical connector 2; when it is not necessary to dock with the box-end electrical connector 2, the waterproof device 1 moves and closes to cover the ship battery box 3 to prevent rain or seawater from entering the ship battery box 3.

[0047] like Figure 3 As shown, the box-end waterproof door 11 is provided with matching parts 112 at both ends in a direction perpendicular to its moving direction to cooperate with an external mechanism to drive the box-end waterproof door 11 to move under the drive of the external mechanism, thereby enhancing the operability and flexibility of the box-end waterproof door 11; by providing matching parts 112 at both ends of the moving direction of the box-end waterproof door 11, it can cooperate with the external mechanism more effectively, so that the box-end waterproof door 11 can be moved more easily under the drive of the external mechanism, so that the ship power replacement can be operated more conveniently, and the stability of the waterproof device 1 is also increased.

[0048] In some preferred embodiments, Figure 3 and Figure 6As shown, the box-end waterproof door 11 is arranged horizontally and is provided with a folded edge 111 at at least one end along its moving direction, and the folded edge 111 extends from the edge of the box-end waterproof door 11 in a direction away from the box-end electrode head 21. The provision of the folded edge 111 can increase the strength of the box-end waterproof door 11 on the one hand; on the other hand, the extension of the folded edge in a direction away from the box-end electrode head can avoid interference or damage to the box-end electrical connector and surrounding structures during the process of opening and closing the door.

[0049] In some preferred embodiments, Figure 3 As shown, the present embodiment also includes a box-end electrical connector 2, which has a box-end electrode head 21 arranged downward and a sealing ring 22 arranged circumferentially around the box-end electrode head 21, the box-end waterproof door 11 is located below the box-end electrode head 21 and moves horizontally, the end of the folded edge 111 connected to the box-end waterproof door 11 is the highest point, and the other end of the folded edge 111 away from the box-end waterproof door 11 is the lowest point, the lowest point is set to be no higher than the lower end surface of the sealing ring 22, and the highest point is set to be no lower than the lower end surface of the sealing ring 22. The sealing ring 22 is arranged around the box-end electrode head 21 to ensure that the outer circumference of the box-end electrode head 21 is isolated from the external environment; further, by setting the height of the folding edge 111 and the sealing ring 22, when the box-end waterproof door 11 is closed, the lower end surface of the sealing ring 22 is squeezed by the box-end waterproof door 11 and fits on the box-end waterproof door 11, so that a sealed space is formed at the box-end electrode head 21, thereby ensuring that the box-end electrode head 21 is not affected by rain, seawater and humid environment, providing the safety and reliability of the box-end battery box. At the same time, the lowest point of the folding edge 111 is not higher than the lower end surface of the sealing ring 22, so that the box-end waterproof door 11 will not cause damage to the sealing ring 22 during the opening and closing process.

[0050] Furthermore, the box-end electrical connector 2 also includes a floating plate 23 and an elastic device (not shown in the figure), the box-end electrode head 21 is installed at the center of the floating plate 23, and the sealing ring 22 is sleeved on the floating plate 23 and wrapped around the flange around the box-end electrode head 21; the floating plate 23 is provided with a guide hole 231, which is convenient for the docking of the box-end electrode head 21 and plays a role of automatic guidance; the elastic device is arranged below the floating plate 23, and is used in the process of closing the box-end waterproof door 11, so that the box-end waterproof door 11 can squeeze the box-end electrical connector 21 downward to make the floating plate 23 drop, and at the same time, the box-end waterproof door 11 contacts the sealing ring 22 to form a closed space; when the box-end waterproof door 11 is opened, the elastic device makes the floating plate 23 rise, so that the box-end electrode head 21 rises to achieve docking.

[0051] In some preferred embodiments, Figure 3 and Figure 6As shown, the waterproof device 1 also includes a guide mechanism 12 and a limit block 13. The guide mechanism 12 is arranged on both sides of the box-end electrode head 21 along the length direction or width direction of the box-end electrode head 21. The bottom edge of the box-end waterproof door 11 is parallel to the guide mechanism 12, so that the box-end waterproof door 11 is slidably arranged on the guide mechanism 12, thereby forming a sealed space covered on the box-end electrical connector 2, and the sealed space is opened by the movement of the box-end waterproof door 11 to make an electrical connection; the guide mechanism 12 is connected to the box-end waterproof door 11 to guide the box-end waterproof door 11 to move along the length direction or width direction of the box-end electrode head 21, and the limit blocks 13 are respectively arranged at both ends of the guide mechanism 12 along the moving direction of the box-end waterproof door so that the box-end waterproof door 11 stops moving after contacting the limit blocks 13, so as to avoid the box-end waterproof door 11 not opening in place when opening and failing to achieve the electrical connection between the box-end electrode head 21 and the ship-end electrode head, and the box-end waterproof door 11 sliding excessively when closing and affecting the protection of the box-end electrode head 21.

[0052] In some preferred embodiments, the waterproof device 1 further includes a fixed frame 16, and the fixed frame 16 further includes a bottom plate 161 and a mounting plate 162. The bottom plate 161 is fixed to the bottom of the ship battery box 3, and the mounting plate 162 is located on the side of the limit block 13 away from the box end electrode head 21 along the moving direction of the box end waterproof door 11, and the mounting plate 162 is arranged to extend downward so that the limit member 15 is connected between the mounting plate 162 and the box end waterproof door 11 in the horizontal direction. The arrangement of the mounting plate 162 allows the limit member 15 to be connected between the mounting plate 162 and the box end waterproof door 11, so that when the box end waterproof door 11 is not subjected to external force, it is subjected to the pulling force of the mounting plate 162 and the limit member 15 and remains in a preset position, that is, in a closed state.

[0053] In some embodiments, Figure 4 As shown, the box-end waterproof door 11 includes a door body 115 and two fixed brackets 116, the number of guide mechanisms 12 is at least two, the upper ends of the two fixed brackets 116 are respectively connected to the two guide mechanisms 12 located on both sides of the box-end electrode head 21, and the lower ends are respectively connected to the two ends of the door body 115, and the fixed bracket 116 is provided with a first connecting portion 113 for connecting the stopper 15. The box-end waterproof door 11 is provided in a form consisting of a door body 115 and two fixed brackets 116 to enhance the sliding stability of the box-end waterproof door 11; when the box-end waterproof door 11 is single-track, it may tilt to one side of the guide mechanism 12 when sliding. By providing at least two guide mechanisms 12, the box-end waterproof door 11 is more stable when the guide mechanism slides. At the same time, by providing the first connecting portion 113 on the fixed bracket 116, it is convenient to connect the stopper 15 with the fixed bracket 116.

[0054] In some preferred embodiments, there are multiple first connecting parts 113, which are arranged at intervals along the moving direction of the box end waterproof door 11, so that the limiter 15 can be connected to any of the first connecting parts 113 to adjust the pre-tightening force between the box end waterproof door 11 and the mounting plate 162. The adjustment of the pre-tightening force between the box end waterproof door 11 and the mounting plate 162 is achieved by the cooperation of multiple first connecting parts 113 and the limiter 15; since the limiter 15 can be connected to any first connecting part 113, the limiter 15 can have different pre-tightening forces by connecting the limiter 15 to different first connecting parts 113; over time, the limiter 15 may experience fatigue, thereby affecting its pre-tightening effect; however, in the scheme, the operator can adjust the connection position to achieve fine-tuning of the pre-tightening force of the limiter, thereby maintaining the stability and overall performance of the waterproof device for the ship battery box. In this embodiment, the limiter 15 is an elastic structure, such as a tension spring.

[0055] In another embodiment, the box end waterproof door 11 further includes a connecting plate 14 connected to the first connecting portion 113, and a plurality of second connecting portions 141 are provided on the connecting plate 14 and are arranged at intervals along the moving direction of the box end waterproof door, and the stopper is connected to one of the second connecting portions 141, and the first connecting portion 113 is connected to any other second connecting portion 141 to adjust the preload force between the box end waterproof door 11 and the mounting plate 162. The preload force between the box end waterproof door 11 and the mounting plate 162 can be further adjusted by providing the second connecting portion, and the reliability of the stopper 15 is ensured.

[0056] In some preferred embodiments, the door body 115 is provided with extensions at both ends along the direction perpendicular to the moving direction of the box end waterproof door 11, and the extensions are provided with grooves that are recessed toward the box end waterproof door 11 to form a matching portion 112; however, it should be understood that the matching portion in the form of a groove in this embodiment is only preferred, and any structure that can realize the external mechanism driving the box end waterproof door 11 to move through the matching portion can be used as the matching portion 112, such as a hole and a mortise and tenon structure. By providing the matching portion 112 at both ends of the door body 115, the forces at both ends of the box end waterproof door 11 are balanced when the external mechanism cooperates with the matching portion 112 to drive the box end waterproof door 11 to move, so that it can move smoothly during the opening and closing process, avoiding problems such as uneven opening and closing due to uneven forces; secondly, the matching portion 112 is set as a groove, which makes the structure of the matching portion simple and easy to manufacture, and also facilitates the external mechanism to cooperate with the groove to act on the box end waterproof door 11, thereby improving the matching reliability.
