[0031] The technical solution of the present application will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application.

[0032] In addition, the technical features involved in different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other. The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements with the same or similar functions.

[0033] The first aspect of the present application provides a take-over mechanism, which is used to connect with a docking mechanism so that cooling water can flow in and out of the take-over mechanism. The docking mechanism is an interface of an external water cooling system. The water cooling system has at least one circulation branch, and the circulation branch includes: a water tank, a heat exchanger and a circulation pump. The water tank is used to store cooling water; the heat exchanger is used to cool the returned cooling water, and the circulation pump is used to provide power for the cooling water in the circulation loop.

[0034] See also Figure 1 and Figure 2 , Figure 1The figure shows a schematic structural view of one perspective of the takeover mechanism 10 according to some embodiments of the present application; Figure 2 The figure shows a schematic structural view of another perspective of the takeover mechanism 10 according to some embodiments of the present application. In some embodiments of the present application, the takeover mechanism 10 includes: a driving member 11, a mounting base 12, and two sleeve assemblies 13. The driving member 11 is connected to the mounting base 12, and the two sleeve assemblies 13 are both fixedly arranged on the mounting base 12; the driving member 11 is used to drive the mounting base 12 to move, so as to drive the sleeve assemblies 13 arranged on the mounting base 12 to move to a preset position, so that the sleeve assemblies 13 are connected to the docking mechanism 20 (see Figure 8 ).

[0035] Among them, the preset position is where the sleeve assembly 13 of the takeover mechanism 10 is connected to the docking mechanism 20 (see Figure 8 ). The docking mechanism 20 and its specific structure will be specifically described in the following embodiments.

[0036] When the takeover mechanism 10 is connected to the docking mechanism, cooling water enters the takeover mechanism 10 through the docking mechanism 20, and after heat exchange, it returns to the docking mechanism 20 from the takeover mechanism 10 again. After cooling is completed, the takeover mechanism 10 resets from the preset position to be separated from the external water cooling system. Among them, the flow direction of the cooling water is shown in the arrow in Figure 1 .

[0037] For the takeover mechanism 10 of the present application, the driving member 11 drives the mounting base 12 to move, and the mounting base 12 drives the sleeve assembly 13 to move. When the sleeve assembly 13 moves to be connected to the external water cooling system, the cooling water flows into the takeover mechanism 10 from the sleeve assembly 13 and flows out of the takeover mechanism 10 from the sleeve assembly 13 after heat exchange. That is to say, the takeover mechanism 10 only needs to make the sleeve assembly 13 perform one action to open or stop the state of the external water cooling system, with a simple and compact structure and high working efficiency.

[0038] In one specific embodiment, the driving member 11 can be a driving oil cylinder, the output shaft of the driving oil cylinder is connected to the mounting base 12, and the sleeve assembly 13 is fixedly arranged on the mounting base 12. Among them, the driving oil cylinder drives the mounting base 12 to move linearly back and forth, and drives the sleeve assembly 13 to move linearly back and forth.

[0039] In this embodiment, the driving oil cylinder has high movement accuracy, can improve the accuracy of the movement position of the sleeve assembly 13, and the linear reciprocating movement provided by the driving oil cylinder is simple and efficient.

[0040] Of course, the driving oil cylinder in this embodiment is only for illustrative purposes. Simple deformations of the driving member 11, such as changing the form of the driving member 11; such as setting a transmission device between the driving member 11 and the mounting base 12 to change the movement mode of the takeover mechanism 10, are all within the application concept of the present application.

[0041] Optionally, an oil cylinder cover is provided on the outer cover of the driving member 11, which can ensure the stable and reliable operation of the driving member 11 and facilitate the installation of the driving member 11.

[0042] In one specific embodiment, a clamping plate 15 is provided on the driving member 11. The clamping plate 15 and the mounting seat 12 are respectively arranged at opposite ends of the driving member 11. Two first connectors 17 are fixedly arranged on the clamping plate 15. Two connecting pipes 16 are connected between the two first connectors 17 and the two sleeve assemblies 13. One connecting pipe 16 is configured to input cooling water, and the other connecting pipe 16 is configured to output cooling water.

[0043] Wherein, the connecting pipe 16 is configured to be slightly longer than the length of the driving member 11 and have flexibility to bend or straighten following the movement of the sleeve assembly 13.

[0044] Please refer to Figure 3 and Figure 4 , Figure 3 which shows a schematic structural view of the mounting seat 12 from one perspective of some embodiments of the present application; Figure 4 which shows a schematic structural view of the mounting seat 12 from another perspective of some embodiments of the present application.

[0045] In some specific embodiments, the mounting seat 12 includes: a bottom plate 121, a pipe-clamping vertical plate 122 and a stop plate 123. The pipe-clamping vertical plate 122 and the stop plate 123 are arranged at intervals along the radial direction of the sleeve assembly 13, and both the pipe-clamping vertical plate 122 and the stop plate 123 are arranged on the bottom plate 121.

[0046] The sleeve assembly 13 is clamped on the pipe-clamping vertical plate 122. Specifically, positioning grooves 1222 with openings are formed at opposite ends of the pipe-clamping vertical plate 122. The positioning grooves 1222 are configured to be slightly larger than the cross-sectional area of the sleeve assembly 13. The sleeve assembly 13 is inserted into the positioning grooves 1222 from the openings of the positioning grooves 1222, so that the positioning grooves 1222 can firmly fix the sleeve assembly 13 and it is easy to be taken out from the pipe-clamping vertical plate 122 when the sleeve assembly 13 is replaced.

[0047] Further, the sleeve assembly 13 includes two adjacent pipe-clamping vertical plates 122. The two pipe-clamping vertical plates 122 act together to determine the installation position of the sleeve assembly 13 and improve the installation stability of the sleeve assembly 13.

[0048] In one specific embodiment, the bottom plate 121 further includes two adjacent bushings 1211. The two bushings 1211 are clamped with the output shaft of the driving member 11. The bushings 1211 are located on one side of the bottom plate 121, and the pipe-clamping vertical plate 122 and the stop plate 123 are arranged on the other side of the bottom plate 121.

[0049] One end of the output shaft of the driving member 11 is provided with a clamping portion (not shown), and the sleeve 1211 and the clamping portion are adapted to each other. The clamping portion and the sleeve 1211 cooperate with each other to improve the connection stability between the driving member 11 and the mounting seat 12.

[0050] In a specific embodiment, a pair of elastic washers 124 are disposed on one side of the bottom plate 121 , and two strip-shaped holes 1212 overlapping with the pair of elastic washers 124 are opened on the bottom plate 121 .

[0051] By providing an elastic washer 124 and a strip hole 1212 on the bottom plate 121 and passing a fastener through the elastic washer 124 and the strip hole 1212 , the bottom plate 121 can be flexibly and reliably installed on the cylinder cover of the driving member 11 .

[0052] During the operation of the driving cylinder, the oil pressure of the driving cylinder will drop uncontrollably, causing the sleeve assembly 13 to be in contact with the docking assembly ( Figure 8 ) has limited connection stability.

[0053] See also Figure 5 and Figure 6 , Figure 5 A schematic diagram showing the structure of the sleeve assembly 13 in some embodiments of the present application is shown; Figure 6 A schematic diagram of the exploded structure of the sleeve assembly 13 according to some embodiments of the present application is shown.

[0054] In order to solve the above problem, in a specific embodiment, the take-over mechanism 10 of some embodiments of the present application, the sleeve assembly 13 of the take-over mechanism 10 includes: a tube body 131, a sleeve body 132 and a first elastic member 133, the tube body 131 is inserted into the sleeve body 132, and the sleeve body 132 can move relative to the tube body 131; the first elastic member 133 is sleeved on the tube body 131, and is located in the gap between the sleeve body 132 and the tube body 131.

[0055] When the sleeve assembly 13 is working, the sleeve assembly 13 is driven by the driving oil cylinder to abut against the guide sleeve 23, the sleeve body 132 abuts against the guide sleeve 23, the guide sleeve 23 abuts against the first elastic member 133, and the first elastic member 133 is compressed by force. When the hydraulic pressure of the driving oil cylinder decreases, the sleeve body 132 and the guide sleeve 23 have a tendency to separate from each other, and the first elastic member 133 restores elastic deformation to drive the sleeve body 132 to have a tendency to move away from the tube body 131, so as to continue to abut against the guide sleeve 23.

[0056] The sleeve assembly 13 of the present embodiment is configured as a tube body 131, a sleeve body 132 and a first elastic member 133 so that the sleeve assembly 13 itself has elasticity. When the driving cylinder is gracefully lowered, the first elastic member 133 restores its elastic deformation so that the sleeve assembly 13 can still press against the crossing assembly, thereby improving the stability of the connection between the sleeve assembly 13 and the guide sleeve 23.

[0057] Furthermore, the tube body 131 includes: a mounting flange 1311 , an extension portion 1312 and a flange 1313 . The extension portion 1312 is disposed on the mounting flange 1311 and extends from one side of the mounting flange 1311 . The flange 1313 is disposed on the outer periphery of the extension portion 1312 .

[0058] One end of the first elastic member 133 abuts against the flange 1313, and the other end is connected to the mounting flange 1311 of the sleeve 132. When the sleeve assembly 13 is working, the flange 1313 presses the first elastic member 133; when the hydraulic pressure of the driving cylinder decreases, the first elastic member 133 restores elastic deformation to ensure that the installation of the sleeve 132 is stable and reliable.

[0059] The mounting flange 1311 is a circular plate with mounting holes distributed in an annular shape, and a second joint 18 is arranged on the mounting flange 1311. The second joint 18 is fixedly mounted through the mounting flange 1311, so that the installation of the connecting pipe 16 is stable and reliable.

[0060] The butt jointing accuracy between the sleeve mechanism and the butt jointing mechanism 20 is high. In actual work, the sleeve mechanism and the butt jointing mechanism 20 may be inaccurate or even misaligned, which affects the working stability of the sleeve mechanism.

[0061] Please refer to Figure 1 , Figure 3 and Figure 7 , Figure 1 A schematic structural diagram of a takeover mechanism 10 from one perspective of some embodiments of the present application is shown; Figure 3 A schematic structural diagram of a mounting base 12 from one viewing angle in some embodiments of the present application is shown; Figure 7 A schematic structural diagram of the ejector pin assembly 14 according to some embodiments of the present application is shown.

[0062] In a specific embodiment, the connecting mechanism 10 further includes an ejector assembly 14 , and the ejector assembly 14 is penetrated on the mounting seat 12 .

[0063] Specifically, a first through hole 1221 is formed on the pipe clamping vertical plate 122 of the mounting seat 12 , a second through hole 1231 is formed on the stop plate 123 , and the ejector assembly 14 is inserted into the first through hole 1221 and the second through hole 1231 .

[0064] The working principle of the take-over mechanism 10 is as follows: when the take-over mechanism 10 is driven to move toward the docking mechanism 20, the driving member 11 drives the mounting seat 12 to move, and the mounting seat 12 drives the ejector assembly 14 to move synchronously, and the ejector assembly 14 can move with the docking assembly 20 ( Figure 7 Correspondingly, when the connecting mechanism is driven to move away from the docking mechanism 20, the driving member 11 drives the mounting seat 12 to move, and the mounting seat 12 drives the ejector assembly 14 to move synchronously, and the ejector assembly 14 is separated from the docking mechanism 20.

[0065] Furthermore, the ejector pin assembly 14 includes: a needle body 141, an insertion rod 142, a second elastic member 143, a first limiting member 144 and a second limiting member 145. The needle body 141 is inserted at one end of the insertion rod 142 and can slide in and out along the direction in which the insertion rod 142 extends. The second elastic member 143 is sleeved on the insertion rod 142 and is located between the first limiting member 144 and the second limiting member 145. The first limiting member 144 can be movably sleeved on the insertion rod 142 and is arranged close to the needle body 141. The second limiting member 145 is fixedly arranged on the insertion rod 142.

[0066] The working principle of the ejector assembly 14 is as follows: when the connecting mechanism is driven to move toward the docking mechanism 20, the driving member 11 drives the mounting seat 12 to move, and the needle body 141 moves synchronously with the mounting seat 12 to dock with the docking mechanism 20. When the needle body 141 abuts against the docking mechanism 20, the needle body 141 is pushed back and moves along the insertion rod 142 toward the second limiter 145. The needle body 141 drives the first limiter 144 to move toward the second limiter 145 to compress the second elastic member 143 located between the first limiter 144 and the second limiter 145. Correspondingly, when the connecting mechanism is driven to move away from the docking mechanism 20, the moving member drives the mounting seat 12 to move, and the needle body 141 moves synchronously with the mounting seat 12 to separate from the docking mechanism 20, and the second elastic member 143 restores elastic deformation so that the needle body 141 continues to abut against the docking assembly.

[0067] In this embodiment, a second elastic member 143 is provided in the ejector assembly 14 , and when the oil pressure of the driving cylinder decreases, the second elastic member 143 is controlled to restore elastic deformation to abut against the needle body 141 , so as to ensure the working stability of the ejector assembly 14 .

[0068] The needle head is configured as a truncated cone column, and the cross-sectional area of ​​one end facing the docking mechanism 20 is relatively small, which can play a precise guiding role and further improve the working stability of the ejector assembly 14.

[0069] In an alternative embodiment, the ejector mechanism includes: a needle body 141 and an insertion rod 142, wherein the needle body 141 is fixedly disposed at one end of the insertion rod 142. That is, the needle body 141 is rigidly connected to the docking mechanism 20.

[0070] In another alternative embodiment, the thimble mechanism includes: a needle body 141, a plug rod 142, a second elastic member 143, and a first limiting member 144. The needle body 141 is inserted into one end of the plug rod 142 and can slide in and out along the extending direction of the plug rod 142. The second elastic member 143 is sleeved on the plug rod 142 and is located between the first limiting member 144 and the needle body 141. That is, on the basis of the original embodiment, the second limiting member 145 is cancelled. On the premise of achieving the corresponding functions, the second limiting member 145 is omitted, so that the structure of the thimble assembly 14 is simple and compact, and it is easy to assemble.

[0071] The second aspect of the present application provides a docking device. Please refer to Figure 8 and Figure 9 , Figure 8 which shows a schematic structural diagram of the adapter 100 in some embodiments of the present application; Figure 9 which shows an exploded structural diagram of the adapter 100 in some embodiments of the present application.

[0072] In a specific embodiment, the adapter 100 includes: the adapter mechanism 10 in any of the above embodiments and a docking mechanism 20, and the adapter mechanism 10 is used to connect with the docking mechanism 20.

[0073] For the docking device of the present application, by adopting the adapter mechanism 10 in any of the above embodiments, the adapter mechanism 10 drives the movement of the mounting seat 12 through the driving member 11, and the mounting seat 12 then drives the movement of the sleeve assembly 13. When the sleeve assembly 13 moves to be connected with the docking mechanism 20, the cooling water flows into the adapter mechanism 10 from the sleeve assembly 13 and flows out of the adapter mechanism 10 from the sleeve assembly 13 after heat exchange.

[0074] That is to say, the adapter mechanism 10 only needs to make the sleeve assembly 13 perform one action to open or stop the state of the external water cooling system. The structure is simple and compact, and the working efficiency is high. The docking device can improve the docking stability with the external water cooling system.

[0075] Please refer to Figure 8 , Figure 9 and Figure 10 , Figure 10 which shows a schematic structural diagram of the docking mechanism 20 in some embodiments of the present application. In some specific embodiments, the docking mechanism 20 includes: a valve 21, a mounting valve seat 22, and a guiding sleeve 23. The valve 21 is fixedly installed on the mounting valve seat 22, and the guiding sleeve 23 is fixed on the mounting valve seat 22. The direction of the circulating flow of the cooling water is exemplarily illustrated by referring to the arrow direction in Figure 8 .

[0076] Specifically, the docking mechanism 20 includes two valves 21 arranged in parallel, and the guide sleeve 23 is located between the two valves 21. The two valves 21 are arranged correspondingly to the two sleeve assemblies 13 of the takeover mechanism 10, so that the two valves 21 are respectively docked with the two sleeve assemblies 13. The guide sleeve 23 is arranged correspondingly to the ejector assembly 14, so that the guide sleeve 23 is used to dock with the ejector assembly 14.

[0077] Specifically, the takeover mechanism 100 has a working state and an idle state, and can switch between the working state and the idle state. Figure 8 As shown in FIG. 1 , the take-over mechanism 10 is connected to the docking mechanism 20, the sleeve assembly 13 of the docking mechanism 20 is connected to the valve 21, the two valves 21 are opened, and the ejector assembly 14 extends into the guide sleeve 23, so that the cooling water can flow from the docking mechanism 20 to the take-over mechanism 10, and then flow out from the take-over mechanism 10 to the docking mechanism 20 after heat exchange. The direction of the cooling water flow is as shown in FIG. Figure 8 Indicated by the direction of the arrow.

[0078] Correspondingly, when the takeover mechanism 10 is in an idle state (such as Figure 9 As shown in the figure, the take-over mechanism 10 is separated from the docking mechanism 20, the sleeve assembly 13 of the docking mechanism 20 is separated from the valve 21, the ejector assembly 14 is separated from the guide sleeve 23, and the two valves 21 are closed to separate the take-over mechanism 10 from the cooling water. In this way, the working state switching of the take-over device 100 is simple and reliable.

[0079] Furthermore, the water outlet of one of the connecting pipes 100 is connected to the water inlet of one of the valves 21 , and the water inlet of the other connecting pipe 100 is connected to the water outlet of one of the valves 21 .

[0080] It should be noted again that the docking mechanism 20 is the interface of the external water cooling system. The external water cooling system has at least one circulation branch, and the circulation branch includes: a water tank, a heat exchanger and a circulation pump. The water tank is used to store cooling water; the heat exchanger is used to cool the returned cooling water; and the circulation pump is used to provide power for the cooling water in the circulation loop.

[0081] The third aspect of the present application provides a power transmission vehicle, which is used to transmit electricity to a graphitization furnace, and a conductive electrode is provided on the end wall of the graphitization furnace. When the power transmission vehicle transmits electricity, the power transmission vehicle is connected to the conductive electrode of the graphitization furnace. The conductive electrode on the graphitization furnace is transmitted to the power transmission vehicle, which affects the service life of the power transmission vehicle.

[0082] See also Figure 8 , Figure 9 and Figure 11 , Figure 11The structural schematic diagram of the power supply vehicle according to some embodiments of the present application is shown. To solve the problem of the service life of the power supply vehicle, the power supply vehicle includes: a vehicle body 200, a conductive device 300, and the connecting pipe mechanism 10 of any of the above embodiments. Both the conductive device 300 and the connecting pipe mechanism 10 are provided on the vehicle body 200. The connecting pipe mechanism 10 is provided on the side of the power supply vehicle away from the graphitization furnace and is close to the docking mechanism 20; the conductive device 300 is used to connect with the graphitization furnace and the power transmission busbar to transmit the electricity on the power transmission busbar to the graphitization furnace.

[0083] For the power supply vehicle of the present application, by adopting the connecting pipe mechanism 10 of any of the above embodiments, the connecting pipe mechanism 10 drives the mounting seat 12 to move through the driving member 11, and the mounting seat 12 drives the sleeve assembly 13 to move. When the sleeve assembly 13 moves to be connected with the external water cooling system, the cooling water flows into the connecting pipe mechanism 10 from the sleeve assembly 13 and flows out of the connecting pipe mechanism 10 after heat exchange. During the power transmission process of the power supply vehicle, the conductive device 300 is in direct contact with the conductive electrode of the graphitization furnace, and the conductive device 300 is connected to the connecting pipe mechanism 10 to cool the cooling water of the conductive device 300 and the connecting pipe mechanism 10. In addition, arranging the water tank, heat exchanger and circulation pump of the water cooling system outside the power supply vehicle can greatly simplify the structure of the power supply vehicle and reduce the production cost of the power supply vehicle.

[0084] When the power supply vehicle conducts power transmission, when the power supply vehicle moves to a preset furnace position of a certain graphitization furnace, the conductive device 300 is connected to the power transmission busbar and is connected to the conductive electrode of the graphitization furnace, and the connecting pipe mechanism 10 is controlled to be connected to the docking mechanism 20. After the cooling water enters the connecting pipe mechanism 10, it exchanges heat with the conductive device 300 and then leaves from the connecting pipe mechanism 10. When the power supply vehicle finishes power transmission, the conductive device 300 is separated from the power transmission busbar and is separated from the conductive electrode of the graphitization furnace, and the connecting pipe mechanism 10 is controlled to be connected to the docking mechanism 20.

[0085] It should be noted that: the docking mechanism 20 is arranged on one side of the preset furnace position of the graphitization furnace and is exactly fixed at a position for cooperating with the connecting pipe mechanism 10.

[0086] Obviously, the above embodiments are only examples clearly described and not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or variations derived therefrom still fall within the protection scope of the creation of the present application.
