Description

Technical Field

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

[0002] Since many inland ports do not have suitable conditions for building charging pile infrastructure, battery swapping has become one of the main technical development routes in the field of electric ships. Since the humid environment of the port is not friendly to the charging and swapping of battery packs, charging stations are generally built at a certain distance from the port, so that the battery packs will be transported and exchanged between the charging station and the port terminal by vehicles.

[0003] Given that ships need to sail in waters, the need for high battery life has become particularly urgent. In order to meet this demand, ships need to be equipped with oversized ship battery boxes to provide sufficient power. In order to achieve rapid replacement of ship battery boxes, ship battery boxes are usually locked on the ship deck, exposing them to the open air. Therefore, the replacement of ship battery boxes must be carried out in an open air environment. Then, external environmental factors may have a significant impact on the safety of ship battery boxes during the power replacement process, which increases the requirements for the waterproof performance of ship battery boxes. Among them, the requirements for the waterproof performance of the electrical connectors of ship battery boxes should be higher to avoid safety accidents.

[0004] A waterproof device and a ship battery box are disclosed in the patent document with publication number CN116417842A; this solution is provided with a locking mechanism, and a locking hole is provided on the waterproof door for fixing the waterproof door. Although the waterproof door can be reliably fixed, it has the disadvantages of complex structure and high production cost; although this solution has good protection against rainy, snowy weather and water waves, it has defects in protection in environments with high air humidity and easy condensation, and it is easy to cause safety accidents such as equipment short circuit due to condensation on the positive and negative electrodes of the high-voltage terminals. Utility Model Content

[0005] In view of this, the technical problem to be solved by the utility model is to overcome the defects of the waterproof device in the prior art, such as complex structure, high manufacturing cost and difficulty in coping with high air humidity and easy condensation environment. The purpose of the utility model is to provide a waterproof device and a ship battery box, by arranging a sealing member on the side of the waterproof door close to the ship battery box to enhance the sealing effect of the waterproof device, while simplifying the structure of the waterproof device and reducing the manufacturing cost.

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

[0007] The utility model provides a waterproof device, which is arranged on the outside of a ship battery box to protect an electric connector on the ship battery box; the characteristic is that the waterproof device comprises a waterproof door and a mounting seat, the mounting seat is arranged around the circumference of the electric connector, the waterproof door is movably arranged on the mounting seat so as to be relatively opened and closed, and a sealing member is provided on the wall surface of the waterproof door facing the electric connector so as to fit and seal with the mounting seat when the waterproof door is closed.

[0008] In this solution, firstly, the mounting seat is designed so that the waterproof door can slide along the mounting seat to achieve the effect of opening and closing the waterproof door; by arranging a sealing member on the side of the waterproof door close to the ship battery box to strengthen the sealing effect of the waterproof device, the protective performance of the waterproof device is greatly improved, which can avoid the safety accidents caused by equipment short circuit due to condensation due to high air humidity.

[0009] Preferably, the sealing member is disposed along the circumference of the electrical connector at least on a portion of the wall surface where the waterproof door overlaps with the mounting seat when the waterproof door is closed.

[0010] In this solution, the upper part of the sealing member is surrounded and arranged on the wall surface where the waterproof door and the mounting seat overlap, which can save consumables of the sealing member and reduce the manufacturing cost of the waterproof device.

[0011] Furthermore, the mounting seat includes a fixing portion connected to the ship battery box and a frame connected to the fixing portion. Along the moving direction of the waterproof door, limiting portions cooperating with the frame are provided on both sides of the waterproof door, so that the limiting portions move relative to the frame to realize the opening and closing of the waterproof door.

[0012] In this solution, the movement of the waterproof door relative to the frame is achieved through the design of the fixing portion and the frame of the mounting seat; at the same time, limiting portions are provided on both sides of the waterproof door, and the cooperation between the limiting portions and the frame effectively prevents the waterproof door from deflecting and falling off during the movement; since the limiting portions are located on both sides of the waterproof door, the waterproof door can move up and down along the frame, while the movement in the front-to-back direction and left-to-right direction relative to the ship battery box is limited by the limiting portions.

[0013] Preferably, the limiting portion includes a first folded edge extending from both sides of the waterproof door in a direction toward the electrical connector and a second folded edge extending from the first folded edge toward the center of the waterproof door. The end of the frame is located between the waterproof door and the second folded edge and is in contact with the first folded edge so that the waterproof door moves along the guide of the frame.

[0014] In this solution, by designing the limiting portion in the form of a first folded edge and a second folded edge, the waterproof door can achieve up and down movement in the frame while movement in other directions is limited by the first folded edge and the second folded edge; at the same time, the end of the frame is also designed to fit the first folded edge, so that the left and right movement of the waterproof door relative to the ship battery box is limited; and the second folded edge is limited by the frame and the fixed portion, so that the front and rear movement of the waterproof door relative to the ship battery box is limited.

[0015] Furthermore, a first limiting groove is provided above the frame, the opening of the first limiting groove faces upward, and a flange extending downward is provided on the top of the waterproof door. When the waterproof door moves downward to close, the flange extends into the first limiting groove.

[0016] In this solution, when the waterproof door is closed, the upper end of the waterproof door is limited by the first limiting groove above the frame; since the working environment of the ship battery box is on a ship that is prone to shaking, if the waterproof door is not limited when it is closed, it is easy to slip due to the bumps of the ship; by providing a flange at the top of the waterproof door to cooperate with the first limiting groove, the waterproof door can remain relatively still with the ship battery box in the closed state, preventing the movement of the waterproof door from greatly reducing the waterproof effect.

[0017] Preferably, the first limiting groove has a first side wall and a second side wall arranged opposite to each other, and at least one of the first side wall and the second side wall is inclined so that the cross-sectional area of ​​the first limiting groove in the horizontal direction gradually decreases from its opening downward, and the depth of the first limiting groove is greater than or equal to the length of the flange.

[0018] In the present solution, a guiding structure composed of a first side wall and / or a second side wall is provided on the first limiting groove, so that when the waterproof door is closed, the flange can fall into the first limiting groove without too precise a position; specifically, when the flange falls into the first side wall or the second side wall, the flange slides into the first limiting groove through the inclined side wall; and the depth of the first limiting groove is greater than or equal to the length of the flange, so that after the waterproof door falls into the first limiting groove, the flange is completely engaged with the first limiting groove to prevent the waterproof door from slipping after closing.

[0019] Furthermore, the first side wall is arranged adjacent to the waterproof door, the second side wall is located on the side of the first side wall away from the waterproof door, the second side wall is higher than the first side wall and is inclined, and a guide surface extending in a direction away from the second side wall is provided above the first side wall.

[0020] In this solution, the first side wall is close to the waterproof door, and the second side wall is away from the waterproof door. The second side wall is inclined so that the flange is guided by the second side wall. When the flange is close to the second side wall, since the height of the flange needs to be higher than the first side wall, the height of the second side wall is designed to be higher than the first side wall, which limits the flange to ensure that the flange falls into the first limiting groove and does not continue to move toward the position of the second side wall relative to the inner side of the ship battery box. At the same time, the first side wall is also provided with a guiding surface extending away from the second side wall, so that when the flange falls close to the first side wall, it can also be guided by the first side wall to slide into the first limiting groove instead of falling on the upper section of the first side wall and staying.

[0021] Preferably, a second limiting groove is provided at a side of the lower end of the frame facing the waterproof door, the opening of the second limiting groove faces upward, and when the waterproof door moves downward to close, the lower end of the waterproof door extends into the second limiting groove.

[0022] In this solution, a second limiting groove is designed at the lower end of the frame. Since the second limiting groove opens upward, the lower end of the waterproof door falls into the second limiting groove when it is closed, and the waterproof door is limited from the lower end.

[0023] Furthermore, a limiting block is provided at the lower end of the second folded edge toward one side of the frame, so that the lower end of the waterproof door is brought close to the frame and the lower end of the waterproof door is guided to extend into the second limiting groove during the downward movement of the waterproof door.

[0024] In this solution, a limiting block is provided at the lower end of the second folded edge. Since the limiting block is located close to the frame, when the waterproof door slides in the frame, the limiting block moves closer to the frame and is limited, thereby sliding into the second limiting groove in the correct position.

[0025] Preferably, the waterproof device also includes a hanging assembly and a limiting assembly, the hanging assembly includes a hook provided on the ship battery box and located above the mounting seat and a hanging ear provided above the waterproof door, when the waterproof door moves upward to open, the hanging ear cooperates with the hook to keep the waterproof door in an open state, and the limiting assembly is provided on the ship battery box and located above the hook to limit the highest point of the upward movement of the waterproof door.

[0026] In this solution, since the waterproof door needs to remain open and not fall when it is open, a hanging assembly is fixed on the ship's battery box; at the same time, since the waterproof door is easily dislocated from the mounting seat if the height is too high when it is lifted, a limiting assembly is also fixed on the ship's battery box to limit the highest lifting position of the waterproof door.

[0027] Furthermore, a rain shield is provided above the limiting assembly, the rain shield is fixed at the ship battery box, and at least one eaves-like structure extends from a fixed position, and the projection of the eaves-like structure in the vertical plane at least covers the projection of the waterproof device in the vertical plane.

[0028] In the present solution, in order to further prevent the direct scouring of the waterproof device by rainwater or seawater, a rain shield is provided above the limiting component; in order to ensure that water from above the waterproof device flows out along the outside of the rain shield, the coverage area of ​​the rain shield is larger than the component below it, thereby effectively preventing the entire waterproof device from being directly affected by rainwater and / or seawater.

[0029] In a second aspect, the utility model provides a ship battery box, comprising: a box body and the above-mentioned waterproof device, the side of the box body is provided with an electric connector for electrically connecting to an electrical connection device of a battery-exchanging ship to provide electrical energy for the battery-exchanging ship, and the waterproof device is installed on the box body and covers the electric connector to protect the electric connector.

[0030] Compared with the prior art, the beneficial effects that can be achieved by at least one of the above technical solutions adopted in the embodiments of this specification include at least:

[0031] First, the utility model has strong waterproof performance by arranging a sealing member on the inner side of the waterproof door and closely fitting with the fixing seat, which greatly improves the protection performance of the ship battery box and avoids the safety accident of equipment short circuit caused by condensation due to high air humidity;

[0032] Secondly, compared with the prior art, the utility model simplifies and optimizes the structure of the waterproof door, greatly reduces the production cost and makes the production simpler and faster. BRIEF DESCRIPTION OF THE DRAWINGS

[0047] Combination Figure 1-Figure 3 As shown, the present application provides a waterproof device 100, which is mainly used in the field of ship battery replacement, and is arranged on the outside of the ship battery box to protect the electrical connector on the ship battery box. Specifically, the waterproof device 100 includes a waterproof door 1, a seal 2 and a mounting seat 4, the mounting seat 4 is arranged around the circumference of the electrical connector, and the waterproof door 1 is slidably arranged on the mounting seat 4, so as to form a sealed space covered on the ship battery box 101, and the sealed space is opened by moving the waterproof door 1 so that the electrical connector of the ship battery box is electrically connected to the device end to realize the charging and discharging of the battery box. Among them, the device end can be a ship, and the electrical connector of the ship battery box is docked with the ship to discharge to provide energy for the ship to sail; it can also be a charging system in a battery replacement station, and the electrical connector of the ship battery box is docked with the charging system to charge in preparation for the next power replacement. The seal 2 is arranged on the wall of the waterproof door 1 facing the electrical connector, so that when the waterproof door 1 is closed, the gap between the waterproof door 1 and the mounting seat 4 is effectively sealed, so that the protection performance of the waterproof device is greatly improved, and the safety accident of equipment short circuit caused by high air humidity and condensation can be avoided.

[0048] In one embodiment, the mounting seat 4 is composed of a fixing portion 41 and a frame 42, the fixing portion 41 is connected to the ship battery box and a support plate 43 is formed on the side facing the frame 42, the support plate 43 is recessed inward relative to the fixing portion 41 and the frame 42 in the left and right direction perpendicular to the vertical direction, thereby forming a groove structure for the waterproof door 1 to slide with the fixing portion 41 and the frame 42; a screw hole is also provided on the fixing portion 41 to fix the mounting seat 4 as a whole on the ship battery box 101; the sealing space formed by the waterproof door 1 and the mounting seat 4 maintains the protection of the electrical connector, can prevent rainwater from entering the electrical connector, and improve the waterproof performance and safety performance of the ship battery box 101 in the outdoor environment; when the electrical connector of the ship battery box 101 needs to be docked with the equipment end to perform charging and discharging operations, the sliding waterproof door 1 can meet the needs at any time, and electrical connection can be made after opening, the structure is simple, and the waterproofness and safety of the ship battery box 101 can be significantly improved. It should be noted that in other embodiments, the fixing portion 41 and the frame 42 may be integrally formed, and an arc-shaped transition between the two forms a groove-like structure, that is, the support plate 43 may not be provided.

[0049] In another embodiment, the waterproof door 1 may also be moved horizontally along the mounting seat 4 to control the opening and closing of the sealed space.

[0050] Thus, the waterproof device 100 can be set in an openable and closable manner on the ship battery box 101 to protect it; the waterproof device 100 is set at the end face of the ship battery box 101, and an electrical connector accommodating port 102 is set on the side wall of the ship battery box 101 to accommodate the electrical connector, and the waterproof device 100 is set outside the electrical connector accommodating port 102; when it is necessary to dock with the equipment end, the waterproof device 100 moves and opens to expose the electrical connector; when it is not necessary to dock with the electrical connector, the waterproof device 100 moves and closes to cover the electrical connector to prevent rainwater from entering the electrical connector and to avoid condensation, dust, etc. from corroding the electrical connector.

[0051] In one example, if Figure 2 and Figure 3 As shown, the waterproof door 1 is a frame-shaped structure with folded edges on three sides.

[0052] The difference between the embodiments of this specification and the prior art is that Figure 2 and Figure 3 As shown, the waterproof door 1 is movably arranged on the side of the ship battery box 101. Through the cooperation between the sealing member 2 and the mounting seat 4 on the side of the waterproof door 1 close to the ship battery box 101, the electrical connector on the side of the ship battery box 101 is well sealed when the waterproof door 1 is closed, so that when condensation occurs due to high air humidity at sea, the electrical connector on the ship battery box 101 can remain dry.

[0053] It should be pointed out that Figure 2 and Figure 3 The waterproof device 100 shown is disposed on the side of the ship battery box 101. In other embodiments, the waterproof device 100 may also be disposed at the bottom or top of the ship battery box 101, as long as the mutual sealing between the sealing member and the mounting seat is satisfied.

[0054] like Figure 3 As shown, the sealing member 2 in this embodiment is attached to the side of the waterproof door 1 close to the ship battery box 101; when the waterproof door 1 is in a closed state, the sealing member 2 can be tightly attached to the frame to prevent rainwater from entering the electrical connector accommodating port 102; and when the sealing member 2 is in a closed state, a pre-tightening friction force is generated with the attached portion to prevent the waterproof door 1 from slipping or falling off due to bumps during transportation, and the use is safe and reliable.

[0055] It should be pointed out that the seal 2 can be a full-covering design on the inner side of the waterproof door 1 relative to the ship battery box 101, or the seal 2 can be set only on the part where the waterproof door 1 is in close contact with the mounting seat 4, so that the consumables of the seal 2 are reduced, thereby reducing the overall manufacturing cost of the waterproof device 100.

[0056] See again Figure 2 and Figure 3 The waterproof door 1 provided in this embodiment includes a lifting door 11, a lifting handle 13 arranged at the middle position of the top of the lifting door 11, and a limiting part located on both sides of the lifting door 11. The limiting part cooperates with the frame and then moves relative to the frame to realize the opening and closing of the waterproof door, and also effectively prevents the waterproof door from deflecting and falling off during the movement.

[0057] The lifting door 11 is a flat plate 111, and the limiting part includes a first folding edge 114 and a second folding edge 115. The first folding edge 114 extends from the left and right sides of the flat plate 111 in the direction toward the ship battery box or the electrical connector, and the second folding edge 115 extends from the first folding edge 114 toward the center of the flat plate 111, so that the flat plate 111, the first folding edge 114, and the second folding edge 115 form a groove structure, which is covered at the end of the frame in the left and right directions, so that the waterproof door 1 can move in the vertical direction along the frame. At the same time, the second folding edge 115 can also prevent rainwater from flowing to the electrical connector accommodating port 102, ensuring the safety of the charging operation.

[0058] In some embodiments, Figure 2 As shown, the handle 13 has an arched structure that bends away from the ship battery box 101, so that the waterproof door 1 is easy for the operator to pull. When the waterproof door 1 needs to be pulled, the operator is not likely to accidentally touch the ship battery box 101.

[0059] In some embodiments, the top of the lifting door 11 is provided with a flange 113 extending downward and a connecting portion 112 connected between the flange 113 and the flat panel 111, and the width of the connecting portion 112 is not less than the width of the top of the frame, so that when the door is closed, the end of the top of the frame is just located between the flange 113 and the flat panel 111 to play a limiting role. The lifting handle 13 can be provided on the connecting portion 112.

[0060] like Figure 6 and Figure 7 As shown, in this embodiment, the waterproof device also has a limiting mechanism 3, which includes a first limiting groove 32 for limiting the flange 113, the first limiting groove 32 is opened upward and has a first side wall 321 and a second side wall 322 that are oppositely arranged, the first side wall 321 is a side of the first limiting groove 32 that is away from the ship battery box 101, and the second side wall 322 is a side of the first limiting groove 32 that is close to the ship battery box 101 (in other words, the first side wall is arranged adjacent to the waterproof door, and the second side wall is located on the side of the first side wall away from the waterproof door). Further, the second side wall 322 can be tilted so that the cross-sectional area of ​​the first limiting groove 32 in the horizontal direction gradually decreases from its opening downward; it should be understood that in this embodiment, the second side wall 322 is tilted for preference only, and in other embodiments, the first side wall can also be tilted; in addition, when the waterproof door 1 moves downward along the support plate 43 to close the sealed space of the ship battery box 101, the flange 113 formed on the top surface of the waterproof door 1 first abuts against the first side wall 321 of the first limiting groove 32, and then slides downward along the first side wall 321. The first limiting groove 32 is inserted into the first limiting groove 32; accordingly, the depth of the first limiting groove 32 corresponds to the length of the second flange 113, which is specifically embodied as follows: the depth of the first limiting groove 32 is greater than or equal to the length of the second flange 113, so as to realize the limiting function of the waterproof door 1 from the upper side, prevent the waterproof door 1 from shaking relative to the fixing part 41, affect the waterproof performance or generate noise, etc., and improve the stability of the waterproof door 1; the second side wall 322 is set to be hollow, which can reduce materials and manufacturing costs on the one hand; on the other hand, it is also convenient for operators to observe the closing status of the waterproof door 1. Further, such a structural design allows rainwater falling on the top of the lifting door 11 to flow into the first limiting groove 32 along the flange 113, and flow into the fixing part 41 and the support plate 43 from the positions of the first limiting groove 32 corresponding to the two sides of the lifting door 11, and can be discharged along the support plate 43; and prevent rainwater from entering the electrical connector accommodating port 102.

[0061] In some preferred embodiments, the vertical height of the second side wall 322 is higher than that of the first side wall 321; it can be understood that when the flange 113 of the waterproof door falls into the first limiting groove 32, the flange 113 is higher than the first side wall 321 in the vertical direction; therefore, when the flange 113 approaches the side of the ship battery box 101, in order to ensure that the flange 113 falls into the first limiting groove 32, the second side wall 322 is set to be higher than the first side wall 321, so that the flange 113 is limited by the second side wall 322 and will not move to the inner position of the second side wall 322 relative to the ship battery box 101, thereby leaving the first limiting groove 32.

[0062] like Figure 7 As shown, in this embodiment, the limiting mechanism 3 further includes a second limiting groove 33, which is arranged at the lower end of the frame 141 toward the waterproof door, and the opening is arranged upward to realize the limiting function of the waterproof door 1 from the lower end, and combined with the upper end limiting function, further prevents the waterproof door 1 from shaking relative to the fixing part 41, ensures the stability of the waterproof door 1 on the fixing part 41, and ensures the waterproof performance. The second limiting groove 33 also provides a supporting platform for the waterproof door 1 to prevent the waterproof door 1 from sliding to the ground.

[0063] like Figure 5 As shown, in this embodiment, the frame 42 has an upper end 421 and a lower end 422; the bottom plate 331 of the second limiting groove 33 is a surface attached to the lower end 422, and the end surface of the bottom plate 331 away from the frame 141 extends upward to form a longitudinal plate 332, and the second limiting groove 33 is formed between the longitudinal plate 332 and the lower end 422; the upper end of the longitudinal plate 332 also extends obliquely outward to form a guide portion 333, and the guide portion 333 is used to guide the waterproof door 1; the second limiting groove 33 can be set to gradually increase the opening from bottom to top, or the opening can be increased only at the guide portion 333. When the waterproof door 1 is closed, the falling waterproof door 1 first contacts the guide portion 333, and gradually moves to the second limiting groove 33 between the longitudinal plate 332 and the lower end 422 under the guidance of the guide portion 333, so as to realize the lower side limiting function of the waterproof door 1; in this embodiment, the bottom plate 331 and the longitudinal plate 332 are integrally formed, and in other embodiments, the two can be fixedly connected by welding or the like.

[0064] like Figure 2 and Figure 4As shown, in this embodiment, the limiting mechanism 3 also includes a limiting block 34, which is installed on the side of the second folding edge 115 facing the frame, and can be arranged near the corner of the first folding edge 114 and the second folding edge 115, and is located at the bottom of the waterproof door 1; the bottom end of the second folding edge 115 extends inward (that is, toward the lifting door 11) to form a limiting block mounting plate 341 for fixing the limiting block 34; the limiting block 34 can ensure that the waterproof door 1 slides into the second limiting groove 33 along the guide portion 333 to prevent the waterproof door 1 from sliding into the second limiting groove 33, thereby preventing the waterproof door 1 from sliding into the second limiting groove 33. The water door 1 is offset during the sliding process; the limit block 34 makes the watertight door 1 close to the frame 141, ensuring the sealing effect of the seal 2, and at the same time makes the lower end of the watertight door 1 close to the frame 141 and guides the lower end of the watertight door 1 to extend into the second limit groove 33 during the downward movement of the watertight door 1; but it should be understood that the shape and installation position of the limit block 34 are only preferred. In other embodiments, the limit block can be installed at any position in the area covered by the first folded edge 114 and the second folded edge 115.

[0065] like Figure 2 As shown, in this embodiment, the waterproof device 100 also includes a hanging assembly, which includes a hanging ear 12 and a hook 31.
