[0002] A power supply vehicle is a mobile device that supplies power to a graphitization furnace. The vehicle is equipped with an electrode clamping mechanism. When the vehicle supplies power to the furnace, the electrode clamping mechanism connects with the furnace's conductive electrodes. Heat is conducted from the conductive electrodes to the clamping mechanism, affecting its lifespan.

[0003] In related technologies, the electric transmission vehicle has its own water cooling system to reduce the temperature of the electrode clamping mechanism. However, existing water cooling systems are complex in structure and expensive to use.

[0004] In view of this, a new technical solution is needed to solve the above-mentioned technical problems. Utility Model Content

[0031] The technical solutions of this application will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0032] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other. Embodiments of this application are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout.

[0033] The first aspect of this application provides a connecting device for connection with a docking mechanism to allow cooling water to flow in and out. The docking mechanism serves as an interface with an external water cooling system. The water cooling system includes at least one circulation branch, comprising a water tank, a heat exchanger, and a circulation pump. The water tank stores cooling water; the heat exchanger cools the returning cooling water; and the circulation pump provides power to the cooling water in the circulation loop.

[0034] Please see Figure 1 and Figure 2 , Figure 1A schematic diagram of the structure of the receiver mechanism 10 according to some embodiments of this application is shown from one perspective; Figure 2 This diagram illustrates a structural schematic of the connecting mechanism 10 from another perspective, representing some embodiments of this application. In some embodiments of this application, the connecting 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 both sleeve assemblies 13 are fixedly mounted on the mounting base 12. The driving member 11 drives the mounting base 12 to move, thereby moving the sleeve assemblies 13 mounted on the mounting base 12 to a preset position, so that the sleeve assemblies 13 engage with the docking mechanism 20 (see [link]). Figure 8 )connect.

[0035] The preset positions are the sleeve assembly 13 of the connecting mechanism 10 and the docking mechanism 20 (see...). Figure 8 The docking mechanism 20 and its specific structure will be described in detail in the following embodiments.

[0036] With the connecting device 10 connected to the docking device 20, cooling water enters the connecting device 10 via the docking device 20, undergoes heat exchange, and then returns to the docking device 20 from the connecting device 10. After cooling is complete, the connecting device 10 returns to its preset position to separate from the external water cooling system. The flow direction of the cooling water is shown in [reference needed]. Figure 1 The arrow in the image.

[0037] The connection mechanism 10 of this application drives the mounting base 12 to move via the driving component 11. The mounting base 12 then drives the sleeve assembly 13 to move. When the sleeve assembly 13 moves to connect with the external water cooling system, cooling water flows from the sleeve assembly 13 into the connection mechanism 10 and flows out of the connection mechanism 10 after heat exchange. In other words, the connection mechanism 10 only requires the sleeve assembly 13 to perform one action to open or close the connection with the external water cooling system. The structure is simple and compact, and the working efficiency is high.

[0038] In one specific embodiment, the driving component 11 can be a driving cylinder, the output shaft of which is connected to the mounting base 12, and the sleeve assembly 13 is fixedly mounted on the mounting base 12. The driving cylinder drives the mounting base 12 to reciprocate linearly, and in turn drives the sleeve assembly 13 to reciprocate linearly.

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

[0040] Of course, the driving cylinder in this embodiment is only illustrative. Simple modifications to the driving member 11, such as changing the form of the driving member 11, or providing a transmission device between the driving member 11 and the mounting base 12 to change the movement mode of the connecting pipe mechanism 10, are all within the scope of this application.

[0041] Optionally, the drive component 11 is provided with a cylinder cover, which can ensure the stable and reliable operation of the drive component 11 and facilitate the installation of the drive component 11.

[0042] In one specific embodiment, the drive member 11 is provided with a retaining plate 15, which and the mounting base 12 are respectively located at opposite ends of the drive member 11. Two first connectors 17 are fixedly provided on the retaining plate 15, and 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] The connecting tube 16 is configured to be slightly longer than the length of the drive member 11 and is flexible to bend or straighten in response to the movement of the sleeve assembly 13.

[0044] Please see Figure 3 and Figure 4 , Figure 3 A structural schematic diagram of the mounting base 12 according to some embodiments of this application is shown from one perspective. Figure 4 A structural schematic diagram of the mounting base 12 from another perspective is shown for some embodiments of this application.

[0045] In some specific embodiments, the mounting base 12 includes: a base 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 disposed on the base plate 121.

[0046] The sleeve assembly 13 is held in place by the sleeve clamping plate 122. Specifically, each end of the sleeve clamping plate 122 has an opening for a positioning groove 1222. The positioning groove 1222 is configured to be slightly larger than the cross-sectional area of ​​the sleeve assembly 13. The sleeve assembly 13 is inserted into the positioning groove 1222 through the opening of the positioning groove 1222, so that the positioning groove 1222 securely and reliably fixes the sleeve assembly 13 and makes it easy to remove from the sleeve clamping plate 122 when the sleeve assembly 13 is replaced.

[0047] Furthermore, the sleeve assembly 13 includes two adjacent clamping vertical plates 122, which work together to determine the installation position of the sleeve assembly 13 and improve the stability of the sleeve assembly 13 installation.

[0048] In one specific embodiment, the base plate 121 further includes two adjacent bushings 1211, which engage with the output shaft of the drive member 11. The bushings 1211 are located on one side of the base plate 121, and the tube clamping plate 122 and the stop plate 123 are located on the other side of the base plate 121.

[0049] The output shaft of the drive component 11 is provided with a snap-fit ​​part (not shown). The bushing 1211 and the snap-fit ​​part are adapted to each other. The connection stability between the drive component 11 and the mounting base 12 is improved by the cooperation between the snap-fit ​​part and the bushing 1211.

[0050] In one specific embodiment, a pair of elastic washers 124 are provided on one side of the base plate 121, and two strip holes 1212 that overlap with the pair of elastic washers 124 are provided on the base plate 121.

[0051] By providing an elastic washer 124 and a strip hole 1212 on the base plate 121, and by passing fasteners through the elastic washer 124 and the strip hole 1212, the base plate 121 can be flexibly and reliably installed on the cylinder cover of the drive component 11.

[0052] During the operation of the drive cylinder, the oil pressure in the drive cylinder will drop uncontrollably, causing the sleeve assembly 13 to contact the docking assembly ( Figure 8 The connection stability is limited.

[0053] Please see Figure 5 and Figure 6 , Figure 5 A schematic diagram of the sleeve assembly 13 according to some embodiments of this application is shown; Figure 6 An exploded view of the sleeve assembly 13 according to some embodiments of this application is shown.

[0054] To address the aforementioned issues, in one specific embodiment of this application, the connecting device 10 of some embodiments includes a sleeve assembly 13 comprising: a tube body 131, a sleeve body 132, and a first elastic member 133. The tube body 131 passes through the sleeve body 132, and the sleeve body 132 is movable relative to the tube body 131. The first elastic member 133 is sleeved on the tube body 131 and is located within the gap between the sleeve body 132 and the tube body 131.

[0055] When the sleeve assembly 13 is in operation, the sleeve assembly 13 is driven by the hydraulic cylinder to abut against the guide sleeve 23. The sleeve body 132 abuts against the guide sleeve 23, and the guide sleeve 23 abuts against the first elastic element 133, which is compressed under force. When the hydraulic pressure of the driving cylinder decreases, the sleeve body 132 and the guide sleeve 23 tend to separate from each other. The first elastic element 133 restores its elastic deformation, driving the sleeve body 132 to tend to move away from the tube body 131, so as to continue to abut against the guide sleeve 23.

[0056] In this embodiment, the sleeve assembly 13 is configured as a tube body 131, a sleeve body 132 and a first elastic member 133, so that the sleeve assembly 13 itself is elastic. When the drive cylinder descends gracefully, the first elastic member 133 restores its elastic deformation, so that the sleeve assembly 13 can still press against the tribulation assembly, thereby improving the stability of the connection between the sleeve assembly 13 and the guide sleeve 23.

[0057] Furthermore, the pipe body 131 includes: a mounting flange 1311, an extension 1312, and a flange 1313. The extension 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 1312.

[0058] One end of the first elastic element 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 against the first elastic element 133; when the hydraulic pressure of the drive cylinder decreases, the first elastic element 133 restores its elastic deformation to ensure that the sleeve 132 is installed firmly and reliably.

[0059] The mounting flange 1311 is a circular plate with mounting holes arranged in a ring, and a second connector 18 is provided on the mounting flange 1311. The second connector 18 is fixedly mounted by the mounting flange 1311 to ensure stable and reliable installation of the connecting pipe 16.

[0060] The casing mechanism and the docking mechanism 20 require high docking accuracy. In actual operation, the casing mechanism and the docking mechanism 20 may not dock accurately or even misalign, which affects the stability of the casing mechanism.

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

[0062] In one specific embodiment, the receiver 10 further includes a pin assembly 14, which is mounted on the mounting base 12.

[0063] Specifically, the mounting base 12 has a first through hole 1221 on the tube clamping vertical plate 122 and a second through hole 1231 on the stop plate 123. The ejector pin assembly 14 passes through the first through hole 1221 and the second through hole 1231.

[0064] The working principle of the take-up mechanism 10 is as follows: When the take-up mechanism 10 is driven to move toward the docking mechanism 20, the driving component 11 drives the mounting base 12 to move, and the mounting base 12 drives the ejector pin assembly 14 to move synchronously. The ejector pin assembly 14 can engage with the docking assembly 20. Figure 7 Pre-positioning is performed to improve the docking accuracy of the connector assembly. Correspondingly, when the docking mechanism is driven away from the docking mechanism 20, the driving component 11 drives the mounting base 12 to move, and the mounting base 12 drives the ejector pin assembly 14 to move synchronously, and the ejector pin assembly 14 separates from the docking mechanism 20.

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

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

[0067] In this embodiment, a second elastic element 143 is provided inside the ejector pin assembly 14, and the second elastic element 143 is controlled to restore elastic deformation and abut against the needle body 141 when the hydraulic pressure of the driving cylinder drops, so as to ensure the stability of the ejector pin assembly 14 in operation.

[0068] The needle is configured as a frustum, and the cross-sectional area of ​​the 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, with the needle body 141 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 ejector mechanism includes: a needle body 141, an insert rod 142, a second elastic member 143, and a first limiting member 144. The needle body 141 is inserted into one end of the insert rod 142 and can slide in and out along the direction of extension of the insert rod 142. The second elastic member 143 is sleeved on the insert rod 142 and is located between the first limiting member 144 and the needle body 141. That is, the second limiting member 145 is eliminated based on the original embodiment. Under the premise of achieving the corresponding function, the second limiting member 145 is omitted, so that the ejector assembly 14 has a simple and compact structure and is easy to assemble.

[0071] A second aspect of this application provides a docking device. See also... Figure 8 and Figure 9 , Figure 8 A schematic diagram of the structure of a connector 100 according to some embodiments of this application is shown; Figure 9 An exploded structural diagram of a receiver 100 according to some embodiments of this application is shown.

[0072] In one specific embodiment, the connector 100 includes a connector mechanism 10 and a docking mechanism 20 as described in any of the above embodiments, wherein the connector mechanism 10 is used to connect to the docking mechanism 20.

[0073] The docking device of this application adopts the connecting mechanism 10 of any of the above embodiments. The connecting mechanism 10 drives the mounting base 12 to move through the driving member 11. The mounting base 12 then drives the sleeve assembly 13 to move. When the sleeve assembly 13 moves to connect with the docking mechanism 20, cooling water flows into the connecting mechanism 10 from the sleeve assembly 13 and flows out of the connecting mechanism 10 after heat exchange.

[0074] In other words, the connecting mechanism 10 can turn the water cooling system on or off by having the sleeve assembly 13 perform only one action. The structure is simple and compact, the working efficiency is high, and the connector can improve the stability of the connection with the external water cooling system.

[0075] Please see Figure 8 , Figure 9 and Figure 10 , Figure 10 A schematic diagram of the docking mechanism 20 according to some embodiments of this application is shown. In some specific embodiments, the docking mechanism 20 includes: a valve 21, a mounting valve seat 22, and a guide sleeve 23. The valve 21 is fixedly mounted on the mounting valve seat 22, and the guide sleeve 23 is fixedly mounted on the mounting valve seat 22. The direction of cooling water circulation flow is shown in the diagram. Figure 8 The direction of the arrows in the diagram is illustrated by example.

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

[0077] Specifically, the receiver 100 has an operating state and an idle state, and can switch between the operating state and the idle state. When the receiver 10 is in the operating state (e.g. Figure 8 As shown), the connecting mechanism 10 is connected to the docking mechanism 20. The sleeve assembly 13 of the docking mechanism 20 is connected to the valve 21. When both valves 21 are opened, the ejector assembly 14 extends into the guide sleeve 23, allowing cooling water to flow from the docking mechanism 20 to the connecting mechanism 10, undergo heat exchange, and then flow out of the connecting mechanism 10 back to the docking mechanism 20. The direction of cooling water flow is as follows: Figure 8 The direction indicated by the middle arrow.

[0078] Correspondingly, when the takeover mechanism 10 is in an idle state (e.g.) Figure 9 As shown, the connecting mechanism 10 separates from the docking mechanism 20, the sleeve assembly 13 of the docking mechanism 20 separates from the valve 21, the ejector assembly 14 separates from the guide sleeve 23, and both valves 21 are closed to separate the connecting mechanism 10 from the cooling water. In this way, the switching of the working state of the connector 100 is simple and reliable.

[0079] Furthermore, the outlet of one connector 100 is connected to the inlet of one valve 21, and the inlet of the other connector 100 is connected to the outlet of one valve 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 returning cooling water; and the circulation pump is used to provide power for the cooling water in the circulation loop.

[0081] A third aspect of this application provides a power supply vehicle for supplying power to a graphitization furnace, the graphitization furnace having conductive electrodes on its end walls. When the power supply vehicle supplies power, it connects to the conductive electrodes of the graphitization furnace. The conductive electrodes on the graphitization furnace transmit power to the power supply vehicle, affecting its service life.

[0082] Please see Figure 8 , Figure 9 and Figure 11 , Figure 11A schematic diagram of the structure of a power transmission vehicle according to some embodiments of this application is shown. To address the issue of the service life of the power transmission vehicle, the power transmission vehicle includes: a vehicle body 200, a conductive device 300, and a connecting mechanism 10 according to any of the above embodiments. Both the conductive device 300 and the connecting mechanism 10 are disposed on the vehicle body 200. The connecting mechanism 10 is disposed on the side of the power transmission vehicle away from the graphitization furnace and close to the docking mechanism 20. The conductive device 300 is used to connect to the graphitization furnace and the power transmission busbar to transmit electricity from the power transmission busbar to the graphitization furnace.

[0083] The power transmission vehicle of this application employs a connecting mechanism 10 according to any of the above embodiments. The connecting mechanism 10 drives the mounting base 12 to move via a driving component 11. The mounting base 12 then drives the sleeve assembly 13 to move. When the sleeve assembly 13 moves to connect with the external water cooling system, cooling water flows from the sleeve assembly 13 into the connecting mechanism 10 and flows out of the connecting mechanism 10 after heat exchange. During the power transmission process, the conductive device 300 is in direct contact with the conductive electrode of the graphitization furnace. The conductive device 300 is connected to the connecting mechanism 10 to cool the cooling water of the connecting mechanism 10. In addition, by arranging the water tank, heat exchanger, and circulating pump of the water cooling system outside the power transmission vehicle, the structure of the power transmission vehicle can be greatly simplified and the production cost of the power transmission vehicle can be reduced.

[0084] When the power transmission vehicle is supplying power, upon reaching a preset furnace position of a graphitization furnace, the conductive device 300 connects to the power transmission busbar and then to the conductive electrodes of the graphitization furnace. The connecting pipe mechanism 10 is then controlled to connect to the docking mechanism 20. Cooling water enters the connecting pipe mechanism 10, exchanges heat with the conductive device 300, and then exits through the connecting pipe mechanism 10. When the power transmission vehicle stops supplying power, the conductive device 300 separates from the power transmission busbar and the conductive electrodes of the graphitization furnace, and the connecting pipe mechanism 10 is controlled to connect to the docking mechanism 20.

[0085] It should be noted that the docking mechanism 20 is located on one side of the preset furnace position of the graphitization furnace and is fixed in a position that cooperates with the connecting pipe mechanism 10.

[0086] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom still fall within the scope of protection of this application.
