Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of ship battery replacement, in particular to a waterproof device and a ship battery box. BACKGROUND

[0002] Since many inland ports do not have suitable conditions for building charging pile infrastructure, in the field of electric ships, the battery replacement scheme has become one of the main technical development routes. Since the humid environment of the port is not friendly to the charging and replacement of battery packs, the charging station is generally built at a certain distance from the port, so the battery pack is responsible for the transportation and exchange of the ship battery box between the charging station and the port wharf.

[0003] In view of the need for ships to sail in water, the demand for high endurance of batteries becomes particularly urgent. In order to meet this demand, the ship needs to be equipped with a super large ship battery box to provide sufficient power. In order to realize the rapid replacement of the ship battery box, the ship battery box is usually locked on the deck of the ship, which is exposed to the open air. Therefore, the replacement of the ship battery box must be carried out in the open air. Therefore, external environmental factors may have a significant impact on the safety of the ship battery box during the replacement process, which increases the requirement for the waterproof performance of the ship battery box. The waterproof performance requirement of the electrical connector of the ship battery box should be higher to avoid safety accidents.

[0004] The patent document with publication number CN116417842A discloses a waterproof device and a ship battery box; this scheme sets a locking mechanism, and a locking hole is arranged on the waterproof door for fixing the waterproof door, which can realize reliable fixation of the waterproof door, but has the disadvantages of complex structure and high manufacturing cost; this scheme has good protection against rain and snow weather and water waves, but has defects in protection against environments with high air humidity and easy condensation, and is prone to safety accidents such as short circuit of equipment due to condensation of positive and negative poles of high-voltage terminals. SUMMARY

[0005] Therefore, the technical problem to be solved by the present application 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 environments with high air humidity and easy condensation. The purpose of the present application is to provide a waterproof device and a ship battery box, which can enhance the sealing effect of the waterproof device by arranging a sealing element on the side of the waterproof door close to the ship battery box, simplify the structure of the waterproof device, and reduce the manufacturing cost.

[0006] The purpose of the present application is achieved by adopting the following technical solutions:

[0007] The application provides a waterproof device arranged outside a ship battery box to protect an electric connector on the ship battery box, characterized in that the waterproof device comprises a waterproof door and a mounting seat, the mounting seat is arranged around the electric connector, the waterproof door is movably arranged in the mounting seat and can be opened and closed, and a sealing element is arranged on the wall surface of the waterproof door facing the electric connector to seal the mounting seat when the waterproof door is closed.

[0008] In the application, the waterproof door can slide along the mounting seat to be opened and closed, a sealing element is arranged on the side of the waterproof door close to the ship battery box to enhance the sealing effect of the waterproof device, the protection performance of the waterproof device is greatly improved, and the safety accidents caused by short circuit of equipment due to condensation caused by high air humidity can be avoided.

[0009] Preferably, the sealing element is arranged on the wall surface of the waterproof door coinciding with the mounting seat when the waterproof door is closed along the circumference of the electric connector.

[0010] In the application, the sealing element is arranged on the wall surface of the waterproof door coinciding with the mounting seat, the consumption of the sealing element can be saved, and the manufacturing cost of the waterproof device is reduced.

[0011] Further, the mounting seat comprises a fixed part connected with the ship battery box and a frame connected with the fixed part, limit parts cooperating with the frame are arranged on both sides of the waterproof door along the moving direction of the waterproof door, the limit parts are moved relative to the frame to realize opening and closing of the waterproof door, preferably, the limit parts comprise first folding edges extending from both sides of the waterproof door along the direction towards the electric connector and second folding edges extending from the first folding edges towards the center of the waterproof door, the end part of the frame is located between the waterproof door and the second folding edges and is in close contact with the first folding edges, so that the waterproof door moves along the guidance of the frame.

[0012] In the scheme, through the design of the fixed part of the mounting seat and the frame, the movement of the waterproof door relative to the frame is realized; at the same time, the two sides of the waterproof door are provided with limiting parts, and through the cooperation of the limiting parts and the frame, the deviation and falling of the waterproof door during movement are effectively prevented; since the limiting parts are located on the two sides of the waterproof door, the waterproof door can move up and down along the frame, and the movement in the front-rear direction and the left-right direction relative to the ship battery box is limited by the limiting parts; further, by designing the limiting part into the form of the first and second folded edges, the waterproof door realizes the up-down movement in the frame, and the movement in other directions is limited by the first and second folded edges; at the same time, the end part of the frame is also designed to be attached to the first folded edge, so that the left-right movement of the waterproof door relative to the ship battery box is limited; and the second folded edge is limited in the front-rear movement relative to the ship battery box due to the limiting of the frame and the fixed part.

[0013] Further, the upper side of the frame is provided with a first limiting groove, the opening of the first limiting groove faces upward, the top of the waterproof door is provided with a downward extending flange, and when the waterproof door moves downward to close, the flange extends into the first limiting groove; preferably, the first limiting groove has oppositely arranged first and second side walls, at least one of the first and second side walls is inclined to gradually reduce the cross-sectional area of the first limiting groove in the horizontal direction from the opening downward, and the depth of the first limiting groove is greater than or equal to the length of the flange.

[0014] In the scheme, in the closed state of the waterproof door, 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 the ship which is easy to shake, if there is no limiting in the closed state of the waterproof door, it is easy to slip due to the bumping of the ship; by setting a flange on the top of the waterproof door, the flange is matched with the first limiting groove, so that the waterproof door can also remain relatively stationary with the ship battery box in the closed state, preventing the movement of the waterproof door from greatly reducing the waterproof effect; further, by setting a guide structure composed of the first and / or second side walls on the first limiting groove, the flange can fall into the first limiting groove without too accurate position when the waterproof door is closed; specifically, when the flange falls into the first or 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 in the first limiting groove, preventing the waterproof door from slipping after being closed.

[0015] Further, 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 the upper side of the first side wall has a guide surface extending away from the second side wall.

[0016] In the scheme, the first side wall is close to the waterproof door side, the second side wall is away from the waterproof door side, and the second side wall is inclined to guide the folding edge; when the folding edge is close to the second side wall, the height of the folding edge needs to be higher than the first side wall, so the second side wall is designed to be higher than the first side wall to limit the folding edge, so as to ensure that the folding edge falls into the first limiting groove and does not continue to move to the position of the second side wall relative to the inside of the ship battery box; at the same time, the first side wall is also provided with a guide surface extending away from the second side wall, so that when the folding edge falls close to the first side wall, it can also be guided by the first side wall to slide into the first limiting groove, and will not stay on the section behind the first side wall.

[0017] Preferably, the lower end of the frame is provided with a second limiting groove on the side of the waterproof door, the opening of the second limiting groove is upward, and when the waterproof door moves downward to close, the lower end of the waterproof door extends into the second limiting groove.

[0018] In the scheme, the second limiting groove is designed at the lower end of the frame, and the opening of the second limiting groove is upward, so that the lower end of the waterproof door falls into the second limiting groove when the waterproof door is closed, and the lower end of the waterproof door is limited.

[0019] Further, the lower end of the second folding edge is provided with a limiting block on the side of the frame, so that the lower end of the waterproof door is close to the frame and guides the lower end of the waterproof door to extend into the second limiting groove during the downward movement of the waterproof door.

[0020] In the scheme, the limiting block is provided at the lower end of the second folding edge, and the limiting block is located close to the frame, so that when the waterproof door slides in the frame, the limiting block is close to the frame and limited, so as to slide into the second limiting groove at the correct position.

[0021] Preferably, the waterproof device further comprises a hanging assembly and a limiting assembly, the hanging assembly comprises a hook arranged on the ship battery box and located above the mounting seat and a hanging ear arranged 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 arranged on the ship battery box and located above the hook to limit the highest point of upward movement of the waterproof door.

[0022] In the scheme, when the waterproof door is in an open state, it needs to be kept in an open state without falling, so the hanging assembly is fixed on the ship battery box; at the same time, when the waterproof door is lifted, if the height is too high, it is easy to cause the waterproof door to be dislocated from the mounting seat, so the limiting assembly is also fixed on the ship battery box, so as to limit the highest lifting position of the waterproof door.

[0023] Further, the limiting assembly is provided with a rain blocking piece above the limiting assembly, the rain blocking piece is fixed to the ship battery box and extends at least one eave structure from the fixed position, the projection of the eave structure in the vertical plane covers at least the projection of the waterproof device in the vertical plane.

[0024] In the scheme, in order to further prevent rainwater or seawater from directly washing the waterproof device, a rain blocking piece is arranged above the limiting component; in order to ensure that the water from above the waterproof device flows out along the outside of the rain blocking piece, the covering surface of the rain blocking piece is larger than the component below the rain blocking piece, thereby effectively preventing the whole waterproof device from being directly affected by rainwater and / or seawater.

[0025] The application provides a ship battery box in a second aspect, which comprises a box body and the waterproof device, the side of the box body is provided with an electrical connector for electrical connection with an electrical connection device of a battery replacement ship to provide electrical energy for the battery replacement ship, and the waterproof device is installed on the box body and covers the electrical connector to protect the electrical connector.

DETAILED DESCRIPTION

[0039] The embodiments of the present application will be described in detail below with reference to the drawings.

[0040] The above embodiments are only some of the embodiments of the present application, but not all the embodiments. The present application can also be implemented or applied by other different specific embodiments, and the details in the specification can be modified or changed based on different views and applications without departing from the spirit of the present application. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

[0041] It is to be understood that the embodiments described hereinbelow within the scope of the appended claims. It will be apparent to one of ordinary skill in the art that aspects described herein can be implemented in a wide variety of forms, and that any specific structure and / or function described herein is merely illustrative. An aspect described herein can be implemented alone or in combination with any other aspect(s). For example, an apparatus can be implemented using any number and combination of the aspects set forth herein. Additionally, an apparatus can be implemented using other structure and / or functionality not expressly set forth herein.

[0042] In the description of the present specification, it should be noted that unless specifically defined and limited, the terms "mounting", "connection", "connecting" should be understood broadly, for example, it can be fixed connection, or detachable connection, or integral connection; it can be mechanical connection, or electrical connection; it can be direct connection, or indirect connection through intermediate medium, or internal connection of two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances, and cannot be understood as a limitation of the present application.

[0043] In combination Figures 1-3 As shown, the present application provides a waterproof device 100, which is mainly applied to the field of ship battery replacement, and is arranged outside 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 sealing element 2 and a mounting seat 4, the mounting seat 4 is arranged around the electrical connector, and the waterproof door 1 is slidably arranged on the mounting seat 4, thereby forming a sealed space covering the ship battery box 101. The sealed space is opened by moving the waterproof door 1 to facilitate the electrical connection between the electrical connector of the ship battery box and the equipment end, thereby realizing the charging and discharging of the battery box. Wherein, the equipment end can be a ship, and the electrical connector of the ship battery box is connected with the ship to discharge the energy for the ship to sail; or it can be a charging system in the battery replacement station, and the electrical connector of the ship battery box is connected with the charging system to charge for the next battery replacement. The sealing element 2 is arranged on the wall surface of the waterproof door 1 facing the electrical connector, thereby effectively sealing the gap between the waterproof door 1 and the mounting seat 4 when the waterproof door 1 is closed, so that the protection performance of the waterproof device is greatly improved, and the safety accident of short circuit of equipment due to condensation caused by high air humidity can be avoided.

[0044] In one embodiment, the mounting base 4 is composed of a fixed part 41 and a frame 42, the fixed part 41 is connected with the ship battery box and a support plate 43 is formed on the side facing the frame 42, the support plate 43 is recessed inwardly relative to the fixed part 41 and the frame 42 in the left-right direction perpendicular to the vertical direction, thereby forming a groove structure with the fixed part 41 and the frame 42 for the sliding of the waterproof door 1; the fixed part 41 is also provided with a threaded hole for fixing the mounting base 4 as a whole on the ship battery box 101; the sealing space formed by the waterproof door 1 and the mounting base 4 can protect the electrical connector, preventing rainwater from entering the electrical connector and improving the waterproof performance and safety performance of the ship battery box 101 in outdoor environment; when the electrical connector of the ship battery box 101 needs to be connected with the equipment end to perform charging and discharging operation, the slidingly arranged waterproof door 1 can meet the needs at any time, and the electrical connection can be performed after being opened, which is simple in structure and can significantly improve the waterproofness and safety of the ship battery box 101. It should be noted that in other embodiments, the fixed part 41 and the frame 42 can be integrally formed, and the groove structure is formed by arc-shaped transition between the two, that is, the support plate 43 can not be provided.

[0045] In another embodiment, the waterproof door 1 can also move horizontally along the mounting base 4 to control the opening and closing of the sealing space.

[0046] Therefore, the waterproof device 100 can be opened and closed on the ship battery box 101 to protect it; the waterproof device 100 is arranged at the end face of the ship battery box 101, the side wall of the ship battery box 101 is provided with an electrical connector accommodating port 102 for accommodating the electrical connector, and the waterproof device 100 is arranged outside the electrical connector accommodating port 102; when it is needed to be connected with the equipment end, the waterproof device 100 is moved and opened to expose the electrical connector; when it is not needed to be connected with the electrical connector, the waterproof device 100 is moved and closed to cover the electrical connector, preventing rainwater from entering the electrical connector and avoiding corrosion of the electrical connector caused by condensation, dust, etc.

[0047] In one example, as shown in Figure 2 and Figure 3 , the waterproof door 1 is a frame structure with three sides folded.

[0048] The difference between the embodiments of the present specification and the prior art is that, as shown in Figure 2 and Figure 3 , the waterproof door 1 is movably arranged on the side of the ship battery box 101, and the cooperation of the sealing element 2 on the side close to the ship battery box 101 of the waterproof door 1 and the mounting base 4 makes the electrical connector on the side of the ship battery box 101 well sealed in the closed state of the waterproof door 1, so that the electrical connector on the ship battery box 101 can remain dry when condensation occurs due to high air humidity at sea.

[0049] It should be noted 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 on the bottom or top of the ship battery box 101, as long as the seal member and the mounting seat are sealed to each other.

[0050] 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 the 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 the closed state, a pre-tightening friction force is generated with the fitting portion to prevent the waterproof door 1 from slipping or falling off due to bumps during transportation, and the use is safe and reliable.

[0051] It should be pointed out that the seal 2 can be a full-coverage 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.

[0052] 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 in 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 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.

[0053] The lifting door 11 is a flat panel 111. Its retaining feature includes a first hem 114 and a second hem 115. The first hem 114 extends from the left and right sides of the panel 111 toward the ship's battery compartment or electrical connector, while the second hem 115 extends from the first hem 114 toward the center of the panel 111. This creates a groove structure between the panel 111, the first hem 114, and the second hem 115. This groove structure wraps around the left and right ends of the frame, allowing the waterproof door 1 to move vertically along the frame. Furthermore, the second hem 115 prevents rainwater from flowing toward the electrical connector port 102, ensuring safe charging.

[0054] In some embodiments, as Figure 2 As shown, the lifting 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 lift. When the waterproof door 1 needs to be lifted, the operator is unlikely to accidentally touch the ship battery box 101.

[0055] In some embodiments, the top of the lifting door 11 is provided with a downwardly extending flange 113 and a connecting portion 112 connecting the flange 113 and the flat panel 111. The width of the connecting portion 112 is not less than the width of the top of the frame. Therefore, when the door is closed, the end of the top of the frame is located exactly between the flange 113 and the flat panel 111, acting as a limit. The handle 13 can be provided on the connecting portion 112.

[0056] like Figure 6 and Figure 7 As shown, in this embodiment, the waterproof device further 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 the side of the first limiting groove 32 that is away from the ship battery box 101, and the second side wall 322 is the side of the first limiting groove 32 that is close to the ship battery box 101 (or, 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). Furthermore, 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 tilting of the second side wall 322 is only preferred. 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 second sidewall 322 is configured to be hollow, which reduces material consumption and manufacturing costs. Furthermore, it also facilitates operator observation of the closing state of the waterproof door 1. Furthermore, this structural design allows rainwater falling on the top of the lifting door 11 to flow along the flange 113 into the first limiting groove 32 and, from the positions of the first limiting groove 32 corresponding to the sides of the lifting door 11, flow between the fixing portion 41 and the support plate 43, and then drain along the support plate 43, preventing rainwater from entering the electrical connector accommodating opening 102.

[0057] 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, since the flange 113 of the waterproof door falls into the first limiting groove 32, the flange 113 is entirely 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 arranged to be higher than the first side wall 321, so that the flange 113 is limited by the second side wall 322 and cannot move to the inner side of the ship battery box 101, thereby leaving the first limiting groove 32.

[0058] As shown in Figure 7 , in the present embodiment, the limiting mechanism 3 further comprises a second limiting groove 33, which is arranged at the lower end of the frame 141 towards the waterproof door side and is arranged with an upward opening to realize the limiting function of the waterproof door 1 from the lower end, in combination with the upper end limiting function, further preventing the waterproof door 1 from shaking relative to the fixed part 41, ensuring the stability of the waterproof door 1 on the fixed part 41 and ensuring the waterproof performance. The second limiting groove 33 simultaneously provides a supporting platform for the waterproof door 1, avoiding the waterproof door 1 from sliding to the ground.

[0059] As shown in Figure 5 , in the present embodiment, the frame 42 has an upper end part 421 and a lower end part 422; the bottom plate 331 of the second limiting groove 33 is attached to the surface of the lower end part 422, the end face 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 part 422; the upper end of the longitudinal plate 332 further extends outwardly and obliquely to form a guide part 333, which is used for guiding the waterproof door 1; the second limiting groove 33 can be arranged with an opening that gradually increases from bottom to top, or only at the guide part 333; when the waterproof door 1 is closed, the falling waterproof door 1 first contacts the guide part 333 and gradually moves into the second limiting groove 33 between the longitudinal plate 332 and the lower end part 422 under the guidance of the guide part 333, realizing the lower limiting function of the waterproof door 1; in the present embodiment, the bottom plate 331 and the longitudinal plate 332 are integrally formed, and in other embodiments, they can be fixedly connected by welding or other methods.

[0060] As shown in Figure 2 and Figure 4As shown, in the embodiment, the limiting mechanism 3 further comprises a limiting block 34, which is installed on the side of the second folding edge 115 facing the frame, can be arranged close to the corner of the first folding edge 114 and the second folding edge 115, and is located at the lowermost part of the waterproof door 1; the lowermost end of the second folding edge 115 extends inward (that is, towards the sliding 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, preventing the waterproof door 1 from deviating during sliding; the limiting block 34 makes the waterproof door 1 close to the frame 141, ensuring the sealing effect of the sealing member 2, and at the same time makes the lower end of the waterproof door 1 close to the frame 141 to guide the lower end of the waterproof door 1 to extend into the second limiting groove 33 during the downward movement of the waterproof door 1; however, it should be understood that the shape and installation position of the limiting block 34 are only preferred, and in other embodiments, the limiting block can be installed at any position in the area covered by the first folding edge 114 and the second folding edge 115.

[0061] As shown, Figure 2 In the embodiment, the waterproof device 100 further comprises a hanging assembly, which comprises two hanging ears 12 and a hook 31; the two hanging ears 12 are installed on the sliding door 11 and are located on the two sides of the sliding handle 13, respectively; the hook 31 is fixed to the wall surface of the ship battery box 101 and is located above the mounting seat and is fixed by bolts; after the waterproof door is opened, the hanging ears 12 and the hook 31 can be matched to make the waterproof door 1 in the open sealing space state; the hook 31 is of L-shaped structure and has a folding edge at the end to prevent the hanging ears 12 from coming out of the hook 31; when the waterproof door 1 is opened and rises to a specified position, the hanging ears 12 on the waterproof door 1 are hung on the hook 31 on the ship battery box 101, ensuring that the waterproof door 1 is continuously in the open state to perform electrical connection to realize the charging and discharging operation of the ship battery box 101.

[0062] The waterproof device further comprises a limiting assembly 35, which is arranged above the hook 31 and is also fixed to the wall surface of the ship battery box to limit the lifting height of the waterproof door, avoiding that the waterproof door 1 is separated from the mounting seat due to excessive lifting.
