[0002] An electric ship is a type of electric vehicle that can be propelled by electricity generated by battery boxes or marine generators.

[0003] For electric ships using battery boxes, the battery box settings of electric ships are generally divided into fixed and replaceable types. Among them, fixed batteries are generally fixed on the ship, and the ship is directly used as the charging object during charging. The replaceable battery box is generally fixed on the ship through a movable installation. The battery box can be removed to replace or charge the battery box separately. After the replaced battery box is charged, it is reinstalled on the ship.

[0004] The replaceable battery box is usually provided with a cooling pipe, which is connected to the cooling system on the electric ship or the ship battery swap station, and utilizes the circulation of the coolant to achieve thermal balance of the battery box.

[0005] At present, the cooling pipes on the replaceable battery box are rigidly connected to the electric ship or ship battery swap station. Due to frequent replacement, hull vibration and other influences, floating often occurs, resulting in unstable connection of the cooling pipe, which may cause the cooling pipe to disconnect and cause leakage of coolant. Summary of the invention

[0006] The technical problem to be solved by the present invention is to overcome the above-mentioned defect that the cooling pipe of the replaceable battery box in the electric ship in the prior art is prone to leakage, and to provide a liquid cooling connection device with a floating function, an electric ship and a ship battery replacement station.

The liquid cooling connection device includes: a fixed base, a floating mechanism and a guiding mechanism. The floating mechanism is movably arranged on the fixed base. A pipeline joint for connecting with the liquid cooling joint on the battery box is fixed on the floating mechanism. The pipeline joint is connected to the liquid supply device; the guiding mechanism acts on the pipeline joint. The guiding mechanism is used to move the pipeline joint in its plane when performing liquid cooling connection so that it is aligned with the liquid cooling joint on the battery box.

[0009] In this solution, by setting the floating mechanism to move relative to the fixed base, the pipeline structure and the floating mechanism are relatively fixed, so that the pipeline joint can follow the floating mechanism to move relative to the fixed base, which is convenient for docking with the liquid cooling pipeline and avoids the rigid connection of the pipeline joint. During the pipeline joint connection process, the guiding mechanism can move the pipeline joint in a plane, so as to facilitate the alignment of the pipeline joint and the liquid cooling joint, and then facilitate the connection of the pipeline joint and the liquid cooling joint, avoid lateral deviation of the pipeline joint, improve the stability of the pipeline joint, avoid leakage of the pipeline joint, and thus improve the accuracy and reliability of the pipeline joint.

[0023] In this solution, the deformation amount of the first elastic member is adjusted by the waist-shaped hole, so as to better adapt to the use environment, ensure the accuracy of the guiding position, and avoid deformation of the first elastic member due to long-term use.

[0075] The present invention will be described more clearly and completely below by way of embodiments in conjunction with the accompanying drawings, but the present invention is not limited to the scope of the embodiments.

[0076] like Figure 1-Figure 9 As shown, this embodiment is a liquid cooling connection device 100 with a floating function, which can be movably arranged on a base 200, and is used to realize the connection between a liquid supply device with a coolant and a liquid cooling pipeline in a battery box, so that the coolant flows into the liquid cooling pipeline in the battery box. The liquid cooling connection device 100 includes: a fixed base 11, a floating mechanism 20 and a guiding mechanism 40. The floating mechanism 20 is movably arranged on the fixed base 11. A pipe joint 12 for connecting with a liquid cooling joint on the battery box is fixed on the floating mechanism 20, and the pipe joint 12 is connected to the liquid supply device; the guiding mechanism 40 acts on the pipe joint 12, and the guiding mechanism 40 is used to move the pipe joint 12 in its plane when performing liquid cooling connection so that it is aligned with the liquid cooling joint on the battery box. By setting the floating mechanism 20 to move relative to the fixed base 11, the pipeline structure and the floating mechanism 20 are relatively fixedly arranged, so that the pipeline joint 12 can follow the floating mechanism 20 to move relative to the fixed base 11, which is convenient for docking with the liquid cooling pipeline and avoids the rigid connection of the pipeline joint 12. During the connection process of the pipeline joint 12, the guiding mechanism 40 can move the pipeline joint 12 in the plane, so as to facilitate the alignment of the pipeline joint 12 and the liquid cooling joint, and then facilitate the connection of the pipeline joint 12 and the liquid cooling joint, avoid lateral deviation of the pipeline joint 12, improve the stability of the pipeline joint 12, avoid leakage of the pipeline joint 12, and improve the accuracy and reliability of the pipeline joint 12.

[0077] As an embodiment, the guiding mechanism 40 is connected between the floating mechanism 20 and the fixed base 11 in the horizontal direction and the vertical direction in the plane where the floating mechanism 20 is located, so that the pipe joint 12 can move horizontally or vertically in the plane. The guiding mechanism 40 can achieve accurate alignment of the pipe joint 12 and the liquid cooling joint by applying a force to the floating mechanism 20 in the horizontal direction and the vertical direction in the plane, thereby facilitating the connection between the pipe joint 12 and the liquid cooling joint, improving the accuracy and stability of the pipe joint 12, avoiding leakage of the pipe joint 12, and improving the reliability of the pipe joint 12. In other embodiments, the guiding mechanism 40 can also be set in other directions.

[0078] The floating mechanism 20 includes a mounting plate 21 for mounting the pipe connector 12 and arranged parallel to the fixed base 11, a plurality of shafts 22 penetrating the mounting plate 21 and the fixed base 11 to fix the two relative to each other, and a plurality of floating elastic members 23 sleeved on the shafts 22 and clamped between the mounting plate 21 and the fixed base 11. A through hole 24 of a predetermined size is provided on the mounting plate 21 at a position corresponding to the shaft 22. A limiting boss 25 is provided on the shaft 22 at a position located on the inner side of the mounting plate 21. The floating elastic member 23 is clamped between the fixed base 11 and the adjacent limiting boss 25. One end of the shaft rod 22 is set on the fixed base 11, and the other end of the shaft rod 22 is inserted into the through hole 24 of the mounting plate 21. The floating elastic member 23 is clamped between the limiting boss 25 of the shaft rod 22 and the fixed base 11, so that the floating elastic member 23 can apply elastic force to the mounting plate 21 through the limiting boss 25, and then the floating elastic member 23 can make the mounting plate 21 produce a tendency to move away from the fixed base 11, thereby realizing the floating of the mounting plate 21 relative to the fixed base 11.

[0079] In this embodiment, the floating elastic member 23 may be a spring, which is in a compressed state. Threads may be provided at both ends of the shaft 22, one end of the shaft 22 passes through the fixed base 11, the other end of the shaft 22 passes through the through hole 24, and nuts are screwed on both ends of the shaft 22. The shaft 22 limits the maximum distance between the mounting plate 21 and the fixed base 11 through the nuts at both ends. After the external force is transmitted to the mounting plate 21 through the pipe joint 12, the mounting plate 21 can compress the spring, thereby achieving the floating of the mounting plate 21.

[0080] As an embodiment, the diameter of the through hole 24 is larger than the outer diameter of the shaft 22 , which can avoid interference between the side wall of the through hole and the shaft 22 , avoid affecting the movement of the mounting plate 21 , and facilitate centering the mounting plate 21 relative to the fixed base 11 .

[0081] The guiding mechanism 40 includes a plurality of first elastic members 41 disposed on the upper and lower sides of the mounting plate 21 and a plurality of second elastic members 42 disposed on the left and right sides of the mounting plate 21. One end of the first elastic member 41 and the second elastic member 42 are connected to the mounting plate 21 and the other end is connected to the fixed base 11. The first elastic member 41 and the second elastic member 42 are arranged away from the shaft 22. The first elastic member 41 and the second elastic member 42 exert forces on the mounting plate 21 from multiple directions, thereby realizing the guiding and alignment function of the mounting plate 21. The structure is simple and reliable to use.

[0082] There are multiple guiding mechanisms 40, and the multiple guiding mechanisms 40 are symmetrically arranged around the pipe joint 12; the multiple guiding mechanisms 40 are symmetrically and evenly arranged around the pipe joint 12, which can apply force to the floating mechanism 20 in multiple directions, and can further improve the stability and reliability of the floating mechanism 20 and the pipe joint 12.

[0083] The correspondingly arranged shaft rod 22 and floating elastic member 23 constitute a set of floating support components, and the number of floating support components is multiple, and the multiple floating support components are arranged around the outer periphery of the pipe joint 12, and the multiple floating support components are symmetrically arranged relative to the pipe joint 12. The multiple floating support components make the mounting plate 21 more stable during movement, and prevent the pipe joint 12 from lateral deviation.

[0084] A connecting rod 43 is fixedly provided on the mounting plate 21, one end of the connecting rod 43 is passed through the mounting plate 21, the other end of the connecting rod 43 extends toward the fixed base 11, and the first elastic member 41 is connected to the connecting rod 43. The first elastic member 41 acts on the mounting plate 21 through the connecting rod 43, and the structure is simple, and the position of the first elastic member 41 can be flexibly set.

[0085] The fixed base 11 is provided with a connecting plate 44 for connecting with the first elastic member 41, and the connecting plate 44 is adjustable through the waist-shaped hole 48 to adjust the deformation of the first elastic member 41. By adjusting the deformation of the first elastic member 41 through the waist-shaped hole 48, it can better adapt to the use environment, ensure the accuracy of the guiding position, and avoid deformation of the first elastic member 41 due to long-term use.

[0086] The connecting plate 44 is arranged on the side of the fixed base 11 facing the mounting plate 21 and is arranged near the edge. An end of the connecting plate 44 near the edge is provided with an extension plate 45 facing the mounting plate 21. A transition plate 47 is provided at a position corresponding to the extension plate 45 on the end surface of the fixed base 11. The extension plate 45 is fixed to the transition plate 47 by a locking member 46 so that the position of the extension plate 45 can be adjusted. The locking member 46 includes a bolt that penetrates the extension plate 45 and the transition plate 47 in sequence and a nut that matches the bolt. The bolt penetrates the extension plate 45 and the transition plate 47 in sequence and then locks them, so that the mounting plate 21 is reliably fixed to the fixed base 200, and the long-term use of the first elastic member 41 is prevented from causing the position of the connecting plate 44 to be offset. At the same time, the position of the connecting plate 44 can be accurately adjusted by adjusting the locking member 46, thereby achieving accurate adjustment of the deformation of the first elastic member 41, which is convenient for adjusting and fixing the connecting plate 44. The structure is simple and easy to use.

[0087] like Figure 7 As shown, the outer peripheral surface of the connecting rod 43 is provided with a receiving groove 431, the first elastic member 41 is clamped in the receiving groove 431, and the distance between the end surface of the connecting rod 43 and the fixed base 11 is greater than the movement amount of the mounting plate 21 along the shaft 22. The receiving groove 431 is convenient for fixing the first elastic member 41 and can prevent the first elastic member 41 from slipping off.

[0088] In this embodiment, the first elastic member 41 and the second elastic member 42 may both be springs. In other embodiments, the first elastic member 41 and the second elastic member 42 may also be other elastic members.

[0089] The liquid cooling connection device 100 also includes a positioning mechanism 30, which is arranged between the floating mechanism 20 and the fixed base 11 along the floating direction of the floating mechanism 20, and is used to move the pipe joint 12 in its plane so that it is aligned with the liquid cooling joint on the battery box when performing liquid cooling connection. During the connection process of the pipe joint 12, the positioning mechanism 30 can make the pipe joint 12 itself move in a fine-tuned manner in the plane, further increasing the position adjustment amount of the pipe joint 12, thereby facilitating the accurate alignment of the pipe joint 12 and the liquid cooling joint, and then facilitating the connection between the pipe joint 12 and the liquid cooling joint, avoiding lateral deviation of the pipe joint 12, improving the stability of the pipe joint 12, and avoiding leakage of the pipe joint 12, thereby improving the accuracy and reliability of the pipe joint 12.

[0090] The diameter of the through hole 24 is larger than the outer diameter of the shaft 22. The shaft 22 is provided with a limit ring 26 at a position outside the mounting plate 21. The alignment mechanism 30 includes an abutment ring 31 disposed in the through hole 24 near one end of the limit ring 26 and surrounding the shaft 22, and a pagoda spring 32 sandwiched between the abutment ring 31 and the limit boss 25. The two ends of the pagoda spring 32 respectively abut against the abutment ring 31 of the shaft 22 and the limit boss 25 of the mounting plate 21, so that the mounting plate 21 can be driven to align with respect to the shaft 22, and the position of the pipe joint 12 on the mounting plate 21 can be adjusted to avoid the displacement of the mounting plate 21 relative to the shaft 22, thereby making the position of the pipe joint 12 relatively stable, avoiding the lateral displacement of the pipe joint 12, improving the stability of the pipe joint 12, avoiding leakage of the pipe joint 12, and improving the reliability of the pipe joint 12.

[0091] The pagoda spring 32 is in the shape of a pagoda, and has a top end face with the smallest diameter and a bottom end face with the largest diameter, the bottom end face abuts against the abutment ring 31, and the top end face abuts against the limiting boss 25. The small end of the pagoda spring is fixedly arranged relative to the fixed base 11, and the large end of the pagoda spring is fixedly arranged relative to the floating mechanism 20, so that when the floating mechanism 20 is offset, the large end of the pagoda spring moves with the floating mechanism 20, so that the pagoda spring is deformed perpendicular to its own axis, and then the pagoda spring can generate a reset force to drive the floating mechanism 20 to reset and prevent the floating mechanism 20 from deflecting.

[0092] As an embodiment, the pagoda spring 32 can generally refer to a spring with a large end and a small end. From the large end to the small end of the spring, the diameter of the spring gradually decreases.

[0093] The mounting plate 21 further includes a blocking washer correspondingly arranged with the shaft 22. A blocking washer is arranged between the blocking member and the mounting plate 21. The blocking washer can reduce the friction between the pagoda spring 32 and the mounting plate 21, the blocking member and the mounting plate 21, and can improve the flexibility of the movement of the mounting plate 21.

[0094] like Figure 3 As shown, the limiting boss 25 is integrally formed on the shaft rod 22. By integrally forming the limiting boss 25 on the shaft rod 22, the structure is simple and reliable.

[0095] like Figure 5 As shown, the abutment ring 31 is integrally formed in the through hole 24 of the mounting plate 21. The abutment ring 31 is integrally formed in the through hole 24 of the mounting plate 21, which is convenient for processing and manufacturing.

[0096] There are three pipe joints 12, namely a water inlet, a water outlet and a fire outlet. The multiple shafts 22 of the floating mechanism 20 are evenly arranged on the circumference of the pipe joint 12. The water inlet and the water outlet can realize the circulation of the coolant. The fire outlet can deal with sudden fire events. The multiple shafts 22 are evenly arranged on the circumference of the pipe joint 12, which facilitates better alignment of the pipe joint 12.

[0097] exist Figure 1 In the embodiment, three pipe connectors 12 are arranged in a straight line. In other embodiments, the number of pipe connectors 12 may be other values, and the plurality of pipe connectors 12 may be arranged in other forms.

[0098] There are six shafts 22 in the floating mechanism 20, which are respectively arranged at the middle positions of the upper and lower sides of the mounting plate 21 along the length direction and at four end corner positions, and the alignment components are at least arranged on the shafts 22 at the four end corner positions and in the through holes 24. The position setting of the shafts 22 is more reasonable.

[0099] This embodiment also discloses an electric ship, which includes the above-mentioned liquid cooling connection device 100 with floating function. When the liquid supply device of the electric ship is connected to the liquid cooling pipeline in the battery box through the liquid cooling joint of the above-mentioned liquid cooling connection device 100, the liquid cooling joint 12 is accurately connected with the liquid cooling pipeline by moving the liquid cooling joint 12 in its plane, thereby connecting the liquid cooling pipeline, avoiding lateral deviation of the pipeline joint 12, improving the stability of the pipeline joint 12, avoiding leakage of the pipeline joint 12, and thus improving the reliability of the pipeline joint 12.

[0100] This embodiment also discloses a ship battery swap station, which includes the above-mentioned liquid cooling connection device 100 with floating function. When the liquid supply device of the ship battery swap station is connected to the liquid cooling pipeline in the battery box through the liquid cooling joint of the above-mentioned liquid cooling connection device 100, the liquid cooling joint 12 is accurately docked with the liquid cooling pipeline by moving the liquid cooling joint 12 in its plane, thereby connecting the liquid cooling pipeline, avoiding lateral deviation of the pipeline joint 12, improving the stability of the pipeline joint 12, and avoiding leakage of the pipeline joint 12, thereby improving the reliability of the pipeline joint 12.

[0101] As an embodiment, the working process of the liquid cooling connection device 100 with floating function can be described as follows. After the battery box is in place, the liquid cooling connection device 100 moves toward the battery box, and the pipe joint 12 approaches the liquid cooling pipe of the battery box. After the pipe joint 12 and the liquid cooling pipe are engaged in place, the pipe joint 12 of the liquid supply device is connected to the connection valve on the battery box and the flow channel of the connection valve is opened, so that the cooling liquid can circulate between the battery box and the liquid supply device.

[0102] In the process of connecting the pipe joint 12 and the liquid cooling pipeline, if the pipe joint 12 and the liquid cooling pipeline are not aligned, since the pipe joint 12 is installed to the fixed base 11 through the floating mechanism 20, the position of the pipe joint 12 floats relative to the fixed base 11 under the thrust force generated by the initial contact between the two. The alignment mechanism 30 drives the axis of the pipe joint 12 to be parallel to the axis of the shaft 22, that is, the axis of the pipe joint 12 can be perpendicular to the side of the mounting plate 21, so that the pipe joint 12 and the liquid cooling joint can be aligned, which facilitates the connection between the pipe joint 12 and the liquid cooling joint, can avoid lateral deviation of the pipe joint 12, can improve the stability of the pipe joint 12, can avoid leakage of the pipe joint 12, and can improve the reliability of the pipe joint 12.

[0103] Although the specific embodiments of the present invention are described above, it should be understood by those skilled in the art that this is only for illustration and the protection scope of the present invention is defined by the appended claims. Those skilled in the art may make various changes or modifications to these embodiments without departing from the principles and essence of the present invention, but these changes and modifications all fall within the protection scope of the present invention.
