Description

Technical Field

[0001] The invention relates to the technical field of graphitization furnaces, in particular to a graphitization furnace device and a mobile power transmission method thereof. Background Art

[0002] The graphitization furnace is mainly used for the sintering and graphitization of carbon materials, graphitization of PI films, graphitization of thermal conductive materials, sintering of carbon fiber ropes, sintering and graphitization of carbon fiber filaments, purification of graphite powder and other high-temperature treatments that can be graphitized under carbon environments. Its operating temperature is as high as 3000°C, with high production efficiency, energy saving and power saving. It is equipped with an online temperature measurement and temperature control system, which can monitor the temperature in the furnace in real time and adjust it automatically. Since the carbon crystals smelted in the graphitization furnace need to be maintained at a temperature above 2000°C for a period of time to form a material with natural graphite properties, and the final product needs to be cooled to below 200°C to form a primary product with graphite properties, so after the current heating furnace is burned, a cooling process is required. At this stage, the power supply device needs to be shut down, and the next furnace needs to be prepared for smelting. During this process, it needs to be powered on and off.

[0003] In order to improve the utilization rate of the site, during the construction of the graphitization furnace, multiple Acheson graphitization furnaces are arranged in an array, and between two rows of Acheson graphitization furnaces, one end of each row of Acheson graphitization furnaces needs to be equipped with a power transmission car, that is, two power transmission cars are needed between the two rows of Acheson graphitization furnaces, resulting in excessively high use costs. In addition, the graphitization furnace groups are connected side by side with each other, and they need to switch back and forth between power on and power off during operation. Therefore, after a power outage, the connecting nuts between the graphitization furnace and the power transmission busbar are manually removed by the staff, which requires a lot of manpower and time, and is inconvenient to operate; in the related art, the patent with publication number CN221781269U discloses a power transmission car device and system, including a car body, a first sliding mechanism and a second sliding mechanism are provided on the car body, a first electrode clamping mechanism is provided on the first sliding mechanism, and a second electrode clamping mechanism is provided on the second sliding mechanism. The utility model sets a first sliding mechanism and a second sliding mechanism on the vehicle body, cooperates with setting a first electrode clamping mechanism on the first sliding mechanism and setting a second electrode clamping mechanism on the second sliding mechanism, so that the first clamping mechanism clamps the conductive electrodes of one row of Acheson graphitization furnaces between two rows of Acheson graphitization furnaces, and the second clamping mechanism clamps the conductive electrodes of another row of Acheson graphitization furnaces between two rows of Acheson graphitization furnaces, so that the same power transmission vehicle equipment can continue to operate to supply power to another row of conductive electrodes after powering one row of conductive electrodes is finished, effectively reducing the use cost of the power transmission vehicle; however, this power transmission vehicle equipment needs to set multiple sets of electrode clamping mechanisms, which has the disadvantages of complex structure and large space occupation. In addition, since the position of the graphitization furnace and its conductive electrode is fixed, after the power transmission vehicle moves to the position corresponding to the graphitization furnace body, it is often difficult to cope with the slight position deviation caused by the uneven ground, which easily leads to poor contact between the conductive electrode and the clamping mechanism, thereby affecting the stable transmission of current. Summary of the invention

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the purpose of the present invention is to provide a graphitization furnace device and a mobile power transmission method thereof, which allows multiple graphitization furnace bodies to share a common electrode assembly for power supply through the cooperation of a common electrode assembly, multiple groups of electrical connection assemblies and a central controller, which significantly reduces the cost of use and improves the flexibility of equipment layout. At the same time, the continuous power supply and power-off operation of the power transmission vehicle are realized through the automatic control of the electrical connection assembly, which improves work efficiency and safety.

[0017] The second aspect of the present invention provides a mobile power transmission method for a graphitization furnace device, which is applied to the graphitization furnace device of the first aspect of the present invention; the method comprises the following steps:

[0018] S100) Positioning and adjustment steps of the power transmission vehicle: preliminarily controlling the power transmission vehicle to move to a position corresponding to the plate body between any two first longitudinal chutes of the common electrode plate; detecting the horizontal state of the power transmission vehicle, and if the uneven ground causes the vehicle body base to tilt, making a small range position adjustment; if the horizontal state still cannot be achieved, continue to move to a position corresponding to the plate body between another two first longitudinal chutes until the power transmission vehicle reaches a horizontal state; when the power transmission vehicle reaches a horizontal state, controlling the electrode clamping mechanism of the power transmission vehicle to connect with the plate body to ensure stable power supply;

[0019] S200) Power supply step: the central controller identifies the target graphitization furnace body that needs power supply, starts the first driving mechanism in the corresponding electrical connection component, drives the male connection terminal to slide along the first longitudinal slide groove to be tightly plugged with the electrical contact groove of the female electrical connection member, and the current is transmitted to the sub-conductive electrode through the common electrode plate, the male connection terminal, the female electrical connection member and the cable to supply power to the graphitization furnace body; ensure that the electrical connection components corresponding to all non-target graphitization furnaces remain disconnected to prevent current from flowing by mistake;

[0020] S300) Power-off step: the central controller identifies the graphitization furnace body that needs to be powered off, starts the first driving mechanism in the corresponding electrical connection assembly, drives the male connection terminal to slide in the opposite direction along the first longitudinal sliding groove until it is disengaged from the electrical contact groove of the female electrical connector, the current is interrupted, and the graphitization furnace body stops heating;

[0021] S400) Repeat the operation steps: When the power supply vehicle completes the power supply to a target graphitization furnace, the central controller identifies the next target graphitization furnace body that needs power supply, and repeats the above positioning, power supply and power off steps to achieve continuous and efficient mobile power supply.

[0022] In the second aspect of the present invention, as an optional embodiment,

[0023] S200) The power supply steps are as follows:

[0024] The first driving mechanism is started, driving the male connection terminal to move along the first longitudinal sliding groove toward the female electrical connection piece, and the male connection terminal is tightly plugged into the electrical contact groove of the female electrical connection piece to form an electrical connection; after the central controller confirms that the electrical connection is successful, it sends a closing signal to the second driving mechanism; the second driving mechanism receives the signal, starts and drives the closing cover to move downward; during the descent of the closing cover, its notch portion is accurately aligned with and accommodates the male connection terminal, ensuring that the male connection terminal will not fall off or shift due to the movement of the closing cover; the closing cover completely covers the female electrical connection piece to form a relatively closed space;

[0025] S300) The power-off steps are as follows:

[0026] When the target graphitization furnace body needs to be powered off, the central controller sends a power-off signal to the second drive mechanism; the second drive mechanism receives the signal and reversely drives the closed cover to move upward; during the rising process of the closed cover, the notch portion thereof gradually leaves the male connection terminal, and the male connection terminal is still firmly maintained in the female electrical connector; the closed cover completely leaves the female electrical connector, exposing the female electrical connector and the male connection terminal; the central controller sends a power-off signal to the first drive mechanism in the corresponding electrical connection assembly, driving the male connection terminal to slide reversely along the first longitudinal slide groove until it is disengaged from the electrical contact groove of the female electrical connector, the current is interrupted, and the heating of the graphitization furnace body stops.

[0027] Compared with the prior art, the embodiments of the present invention have the following beneficial effects:

[0028] 1. According to the graphitization furnace device of the embodiment of the present invention, when power is required, the power transmission vehicle is first controlled to move to the position corresponding to the plate body between any two first longitudinal chutes of the common electrode plate. If the ground at the position is uneven and causes the vehicle body base to tilt to one side, the position of the power transmission vehicle can be further moved in a small range. If it is still tilted, it can be further moved to the position corresponding to the plate body between the other two first longitudinal chutes. When the power transmission vehicle at this position reaches a horizontal state, the electrode clamping mechanism of the power transmission vehicle is controlled to connect with the plate body at this position. Power supply process: The central controller identifies the target graphitization furnace body that needs to be powered and starts the first driving mechanism in the corresponding electrical connection component. The first driving mechanism drives the male connection terminal to slide along the first longitudinal chute until it is tightly plugged into the electrical contact groove of the female electrical connector. The current is transmitted to the sub-conductive electrode through the common electrode plate, the male connection terminal, the female electrical connector and the cable to power the graphitization furnace body. At the same time, the electrical connection components corresponding to all non-target graphitization furnaces will remain disconnected. This means that their male connection terminals will not be plugged into the female electrical connector, so the current will not flow to these graphitization furnaces. Power-off process: The central controller identifies the graphitization furnace body that needs to be powered off, and starts the first drive mechanism in the corresponding electrical connection assembly. The first drive mechanism drives the male connection terminal to slide in the opposite direction along the first longitudinal slide groove until it is disengaged from the electrical contact groove of the female electrical connector. The current is interrupted and the graphitization furnace body stops heating. After the power transmission vehicle completes the power supply to a target graphitization furnace, the central controller identifies the next target graphitization furnace body that needs to be powered on, and repeats the above operation. In this way, the present invention allows multiple graphitization furnace bodies to share a common electrode assembly for power supply through the cooperation of a common electrode assembly and multiple groups of electrical connection assemblies, which significantly reduces the cost of use and improves the flexibility of equipment layout. At the same time, the continuous power supply and power-off operation of the power transmission vehicle is realized through the automatic control of the electrical connection assembly, which improves work efficiency and safety. The cooperation of the first insulating support frame, the first longitudinal slide groove and the drive mechanism ensures the stable transmission of current and the safety of personnel. In addition, this design is not only suitable for flat ground conditions, but also can cope with various complex and changeable ground environments. This enables the graphitization furnace device to exert its excellent performance in a wider range of application scenarios.

[0029] 2. According to the graphitization furnace device of the embodiment of the present invention, a closing component is also arranged above each of the electrical connection components. When the first driving mechanism drives the male connection terminal to slide along the first longitudinal slide groove until it is tightly plugged into the electrical contact groove of the female electrical connector, the central controller will send a signal to the second driving mechanism. After receiving the signal, the second driving mechanism will start and drive the closing cover to move downward. During the descent of the closing cover, the notch portion of the closing cover is aligned with the male connection terminal, allowing the male connection terminal to continue to remain in the female electrical connector until the closing cover is completely covered on the female electrical connector. At this time, the female electrical connector is completely covered by the closing cover, forming a relatively closed space, which effectively prevents graphite dust, debris, etc. in the workshop from entering the interior of the female electrical connector, thereby avoiding the risk of short circuit between the contact seat and the conductive block. When the graphitization furnace body needs to be powered off or maintained, the central controller will send a signal to the second driving mechanism again. After receiving the signal, the second driving mechanism will reversely drive the closed cover to move upward. During the rising process of the closed cover, the notch portion of the closed cover gradually leaves the male connection terminal, but the male connection terminal still remains in the female electrical connector and will not fall off due to the movement of the closed cover. Finally, the closed cover completely leaves the female electrical connector, exposing the female electrical connector and the male connection terminal, which is convenient for the operator to perform power-off operations. In this way, the present invention effectively prevents graphite dust, debris, etc. in the workshop from entering the interior of the female electrical connector through the closing of the closed cover, reducing the risk of short circuit between the contact seat and the conductive block. The design of the notch enables the male connection terminal to remain in the female electrical connector when the closed cover is closed, and there is no need to pull out the male connection terminal every time the power is supplied or disconnected, which greatly improves the convenience of operation. Through the coordinated work of the central controller and the second driving mechanism, the automatic control of the closed cover is realized, and the intelligence level of the entire system is improved.

[0030] 3. According to the graphitization furnace device of the embodiment of the present invention, the second insulating support frame and the first insulating support frame of the present invention are both made of insulating materials, which effectively isolates the direct contact between the current and the base, and prevents the risk of current leakage and short circuit. The design of the male connection terminal also takes safety into consideration, and its first electrical connection part and the second electrical connection part maintain good contact with the slide groove and the electrical contact groove during the sliding process, avoiding sparks or arcs caused by poor contact.

[0031] 4. According to the graphitization furnace device of the embodiment of the present invention, the present invention drives the first electric telescopic rod, and the male connection terminal can slide along the slide groove to achieve electrical contact or separation with the female electrical connector, thereby controlling the power supply of the graphitization furnace body. This design not only improves the flexibility and accuracy of the power supply operation, but also ensures the safety of the device through components such as insulating blocks. The limit rod of the present invention not only prevents the position of the moving seat from shifting during the sliding process, but also enhances the structural stability of the driving mechanism and improves the safety of the power supply operation.

[0032] 5. According to the graphitization furnace device of the embodiment of the present invention, the width of the second longitudinal chute of the present invention is greater than the width of the first longitudinal chute, and the first longitudinal chute can limit the second vertical portion from moving downward in the vertical direction, thus playing a good limiting role. The length of the second longitudinal chute is equal to the length of the first longitudinal chute. This design ensures that the sliding distances of the male connection terminal in the first longitudinal chute and the second longitudinal chute are consistent, thereby ensuring the stability and accuracy of the power supply operation.

[0054] Embodiment 1:

[0055] Please refer to Figure 1-9 As shown, the embodiment provides a graphitization furnace device, including a base 10 and a plurality of graphitization furnace bodies 20 arranged side by side on the base 10, each graphitization furnace body 20 is provided with a sub-conductive electrode; and further including: a common electrode assembly 30, a plurality of electrical connection assemblies 40 and a central controller 50;

[0056] Specifically, the common electrode assembly 30 is arranged on the base 10 and is located on one side of the furnace tail end of the graphitization furnace body 20; the common electrode assembly 30 includes two first insulating support frames 31 and a common electrode plate 32, and the two first insulating support frames 31 are respectively installed on both sides of the base 10; the common electrode plate 32 is horizontally installed between the two first insulating support frames 31; the common electrode plate 32 is provided with a plurality of first longitudinal slide grooves 321 extending along the width direction thereof; the plate body located between any two first longitudinal slide grooves 321 on the common electrode plate 32 is used to connect with the electrode clamping mechanism of the power transmission vehicle;

[0057] Specifically, a group of electrical connection components 40 are provided at the furnace tail end of each graphitization furnace body 20, and each group of electrical connection components 40 includes a female electrical connector 41 having an electrical contact groove 411, a male connection terminal 42 and a first driving mechanism 43; the female electrical connector 41 is installed at the furnace tail end of the graphitization furnace body 20, and the female electrical connector 41 is electrically connected to the corresponding sub-conductive electrode through a cable; the male connection terminal 42 is slidably installed in the first longitudinal slide groove 321, the first driving mechanism 43 is installed on the base 10, and the output end of the first driving mechanism 43 is connected to the male connection terminal 42, and the first driving mechanism 43 is used to drive the male connection terminal 42 to move along the length direction of the first longitudinal slide groove 321 and always keep in contact with the side wall of the first longitudinal slide groove 321, so that the male connection terminal 42 is plugged in or out of the electrical contact groove 411 of the female electrical connector 41, thereby realizing power on or off between the two;

[0058] Specifically, the signal output end of the central controller 50 is connected to the signal input ends of the plurality of first driving mechanisms 43 respectively.

[0059] According to the graphitization furnace device of the embodiment of the present invention, when power needs to be transmitted, the power transmission vehicle is first controlled to move to a position corresponding to the plate body between any two first longitudinal slide grooves 321 of the common electrode plate 32. If the ground at this position is uneven and causes the vehicle base 10 to tilt to one side, the position of the power transmission vehicle can be further moved in a small range. If it is still tilted, it can be further moved to a position corresponding to the plate body between another two first longitudinal slide grooves 321. When the power transmission vehicle at this position reaches a horizontal state, the electrode clamping mechanism of the power transmission vehicle is controlled to connect with the plate body at this position.

[0060] Power supply process: The central controller 50 identifies the target graphitization furnace body 20 that needs power supply, and starts the first drive mechanism 43 in the corresponding electrical connection assembly 40. The first drive mechanism 43 drives the male connection terminal 42 to slide along the first longitudinal slide groove 321 until it is tightly plugged into the electrical contact groove 411 of the female electrical connector 41. The current is transmitted to the sub-conductive electrode through the common electrode plate 32, the male connection terminal 42, the female electrical connector 41 and the cable to power the graphitization furnace body 20. At the same time, the electrical connection assemblies 40 corresponding to all non-target graphitization furnaces will remain disconnected. This means that their male connection terminals 42 will not be plugged into the female electrical connector 41, so the current will not flow to these graphitization furnaces.

[0061] Power-off process: The central controller 50 identifies the graphitization furnace body 20 that needs to be powered off, and starts the first driving mechanism 43 in the corresponding electrical connection assembly 40. The first driving mechanism 43 drives the male connection terminal 42 to slide in the opposite direction along the first longitudinal slide groove 321 until it is disengaged from the electrical contact groove 411 of the female electrical connector 41. The current is interrupted, and the graphitization furnace body 20 stops heating.

[0062] After the power transmission vehicle completes supplying power to a target graphitization furnace, the central controller 50 identifies the next target graphitization furnace body 20 that needs power supply, and repeats the above operation.

[0063] In this way, the present invention allows multiple graphitization furnace bodies 20 to share a common electrode assembly 30 for power supply through the cooperation of a common electrode assembly 30 and multiple groups of electrical connection assemblies 40, which significantly reduces the cost of use and improves the flexibility of equipment layout. At the same time, the continuous power supply and power-off operation of the power transmission vehicle are realized through the automatic control of the electrical connection assembly 40, which improves work efficiency and safety. The cooperation of the first insulating support frame, the first longitudinal slide groove 321 and the driving mechanism ensures the stable transmission of current and the safety of personnel. In addition, this design is not only suitable for flat ground conditions, but also can cope with various complex and changeable ground environments. This enables the graphitization furnace device to exert its excellent performance in a wider range of application scenarios.

[0064] In a preferred embodiment, the first insulating support frame 31 includes a vertical connection portion 311 and a transverse support portion 312; the lower end of the vertical connection portion 311 is connected to the base 10, and the upper end thereof is connected to one end of the transverse support portion 312; the other end of the transverse support portion 312 extends horizontally toward the center line of the base 10; a plug hole is formed on the transverse support portion 312; and the two ends of the common electrode plate 32 are respectively plugged into the plug holes of the two transverse support portions 312.

[0065] On the basis of the above structure, the first insulating support frame 31 (including the vertical connection part 311 and the horizontal support part 312) is made of insulating material, which effectively isolates the direct contact between the current and the base 10, and prevents the risk of current leakage and short circuit. The two ends of the common electrode plate 32 are respectively inserted into the plug holes of the two horizontal support parts 312, so as to achieve a stable connection with the first insulating support frame. This connection method not only simplifies the installation process, but also improves the overall stability and safety of the equipment.

[0066] In a preferred embodiment, the electrical connection component 40 also includes a second insulating support frame 44, which is installed on the base 10, and a second longitudinal slide groove 441 is formed on the second insulating support frame 44 at a position directly above the first longitudinal slide groove; the male connection terminal 42 has a first electrical connection part 421 and a second electrical connection part 422, wherein the first electrical connection part 421 can be slidably inserted into the first longitudinal slide groove 321 and the second longitudinal slide groove 441, and the second electrical connection part 422 has a plug-in part whose shape and size match the electrical contact groove 411.

[0067] On the basis of the above structure, before power supply, the power transmission vehicle adjusts its position according to the ground conditions to ensure its horizontal connection with the common electrode plate 32. At the same time, the first electrical connection part 421 of the male connection terminal 42 is placed in the first longitudinal slide groove 321 and the second longitudinal slide groove 441, ready for power supply operation. When it is necessary to power a certain graphitization furnace body 20, the control system identifies the target furnace body and starts the first driving mechanism 43 in the corresponding electrical connection assembly 40. The first driving mechanism 43 drives the first electrical connection part 421 of the male connection terminal 42 to slide along the first longitudinal slide groove 321 and the second longitudinal slide groove 441 until the plug-in part of the second electrical connection part 422 is tightly plugged into the electrical contact groove 411 of the female electrical connector 41. The current is transmitted to the sub-conductive electrode through the common electrode plate 32, the male connection terminal 42 (including the first electrical connection part 421 and the second electrical connection part 422), the female electrical connector 41 and the cable, thereby powering the graphitization furnace body 20. When it is necessary to cut off the power to a graphitization furnace body 20, the control system identifies the target furnace body and restarts the first drive mechanism 43 in the corresponding electrical connection assembly 40. The first drive mechanism 43 drives the first electrical connection portion 421 of the male connection terminal 42 to slide in the opposite direction along the first longitudinal slide groove 321 and the second longitudinal slide groove 441 until the plug-in portion of the second electrical connection portion 422 is disengaged from the electrical contact groove 411 of the female electrical connector 41. The current is interrupted and the graphitization furnace body 20 stops heating. The second insulating support frame 44 and the first insulating support frame 31 are both made of insulating materials, which effectively isolate the direct contact between the current and the base 10, preventing current leakage and short circuit risks. The design of the male connection terminal 42 also takes safety into consideration. Its first electrical connection portion 421 and the second electrical connection portion 422 maintain good contact with the slide groove and the electrical contact groove 411 during the sliding process, avoiding sparks or arcs caused by poor contact.

[0068] In a preferred embodiment, the first electrical connection portion 421 includes a first vertical portion 4211 and a second vertical portion 4212 interconnected from bottom to top, the width of the first vertical portion 4211 matches the width of the first longitudinal groove 321, and the second vertical portion 4212 matches the width of the second longitudinal groove 441; the width of the second longitudinal groove 441 is greater than the width of the first longitudinal groove 321, and the length of the second longitudinal groove 441 is equal to the length of the first longitudinal groove 321.

[0069] On the basis of the above structure, the width of the second longitudinal slot 441 is greater than the width of the first longitudinal slot 321, and the first longitudinal slot 321 can limit the second vertical portion 4212 from moving downward in the vertical direction, thus playing a good limiting role. The length of the second longitudinal slot 441 is equal to the length of the first longitudinal slot 321. This design ensures that the sliding distances of the male connection terminal 42 in the first longitudinal slot 321 and the second longitudinal slot 441 are consistent, thereby ensuring the stability and accuracy of the power supply operation.

[0070] In a preferred embodiment, the first driving mechanism 43 includes a first electric telescopic rod 431, the output shaft of the first electric telescopic rod 431 passes through the side wall of the second insulating support frame 44 and extends inward, a movable seat 432 is installed on the output shaft of the first electric telescopic rod 431, an insulating block 433 is installed on the outer side of the movable seat 432, a connecting seat 434 is installed on the outer side of the insulating block 433, and the second vertical portion 4212 of the male connecting terminal 42 is connected to the connecting seat 434.

[0071] On the basis of the above structure, when it is necessary to power the graphitization furnace body 20, the control system starts the first electric telescopic rod 431. The output shaft of the electric telescopic rod begins to extend, pushing the moving seat 432, the insulating block 433 and the connecting seat 434 to move inward together. As the moving seat 432 moves, the second vertical portion 4212 of the male connecting terminal 42 also moves accordingly, gradually approaching the female electrical connector 41. When the plug-in portion of the male connecting terminal 42 is aligned with the electrical contact groove 411 of the female electrical connector 41, the first electric telescopic rod 431 stops extending. At this time, the current is transmitted to the sub-conductive electrode through the male connecting terminal 42, the female electrical connector 41 and the cable to power the graphitization furnace body 20. The power-off process is the opposite of the power-on process. When the target graphitization furnace body needs to be powered off, the central controller 50 starts the first electric telescopic rod 431 to shorten its output shaft. The movable seat 432, the insulating block 433 and the connecting seat 434 move outward together, driving the second vertical portion 4212 of the male connecting terminal 42 to gradually move away from the female electrical connector 41. When the plug-in portion of the male connecting terminal 42 completely withdraws from the electrical contact groove 411 of the female electrical connector 41, the current is interrupted and the graphitization furnace body 20 stops heating. In this way, the present invention drives the first electric telescopic rod 431, so that the male connecting terminal 42 can slide along the slide groove to achieve electrical contact or separation with the female electrical connector 41, thereby controlling the power supply of the graphitization furnace body 20. This design not only improves the flexibility and accuracy of the power supply operation, but also ensures the safety of the device through components such as the insulating block 433.

[0072] In a preferred embodiment, the first driving mechanism 43 includes a limiting rod 435 , one end of which is connected to the moving seat 432 , and the other end of the limiting rod 435 slides through the second insulating support frame 44 and extends outward.

[0073] On the basis of the above structure, when the first electric telescopic rod 431 starts and pushes the moving seat 432 to slide, the limiting rod 435 also slides in the second insulating support frame 44. Since the limiting rod 435 is installed on the moving seat 432, it will move with the moving seat 432 and keep the relative position unchanged. The limiting rod 435 maintains close contact with the inner wall of the second insulating support frame 44 during the sliding process, and limits the lateral movement or deviation of the moving seat 432 through friction or guiding action. When the moving seat 432 drives the male connecting terminal 42 to slide to a predetermined position, the limiting rod 435 also stops sliding accordingly and remains in the correct position in the second insulating support frame 44. In this way, the limiting rod 435 of the present invention not only prevents the position deviation of the moving seat 432 during the sliding process, but also enhances the structural stability of the driving mechanism and improves the safety of the power supply operation.

[0074] In a preferred embodiment, a closing component 60 is also provided above each electrical connection component 40, and the closing component 60 includes a closing cover 61 with an open bottom and a second driving mechanism 62, and a notch 611 is provided on one side of the closing cover 61 adjacent to the male connection terminal 42; the closing cover 61 is movably installed on the graphitization furnace body 20 and is located directly above the female electrical connector 41, the output shaft of the second driving mechanism 62 is connected to the closing cover 61, and the signal input end of the second driving mechanism 62 is connected to the signal input end of the central controller 50; the second driving mechanism 62 is used to drive the closing cover 61 to move up and down to cover or open the female electrical connector 41; when the closing cover 61 is descending, the notch 611 part of the closing cover 61 is aligned with the male connection terminal 42, allowing the male connection terminal 42 to continue to remain in the female electrical connector 41.

[0075] When the first driving mechanism 43 drives the male connection terminal 42 to slide along the first longitudinal sliding groove 321 until it is tightly plugged with the electrical contact groove 411 of the female electrical connector 41, the central controller 50 will send a signal to the second driving mechanism 62. After receiving the signal, the second driving mechanism 62 will start and drive the closed cover 61 to move downward. During the descent of the closed cover 61, the notch 611 of the closed cover 61 is aligned with the male connection terminal 42, allowing the male connection terminal 42 to continue to remain in the female electrical connector 41 until the closed cover 61 is completely covered on the female electrical connector 41. At this time, the female electrical connector 41 is completely covered by the closed cover 61, forming a relatively closed space, which effectively prevents graphite dust, debris, etc. in the workshop from entering the interior of the female electrical connector 41, thereby avoiding the risk of short circuit between the contact seat and the conductive block.

[0076] When the graphitization furnace body 20 needs to be powered off or maintained, the central controller 50 will send a signal to the second drive mechanism 62 again. After receiving the signal, the second drive mechanism 62 will reversely drive the closed cover 61 to move upward. During the rising process of the closed cover 61, the notch 611 of the closed cover 61 gradually leaves the male connection terminal 42, but the male connection terminal 42 remains in the female electrical connector 41 and will not fall off due to the movement of the closed cover 61. Finally, the closed cover 61 completely leaves the female electrical connector 41, exposing the female electrical connector 41 and the male connection terminal 42, which is convenient for the operator to perform the power-off operation.

[0077] In this way, the present invention effectively prevents graphite dust, debris, etc. in the workshop from entering the interior of the female electrical connector 41 by covering the closed cover 61, reducing the risk of short circuit between the contact seat and the conductive block. The design of the notch 611 allows the male connection terminal 42 to remain in the female electrical connector 41 when the closed cover 61 is covered, and there is no need to unplug the male connection terminal 42 every time the power is turned on or off, which greatly improves the convenience of operation. Through the coordinated work of the central controller 50 and the second drive mechanism 62, the automatic control of the closed cover 61 is realized, and the intelligence level of the entire system is improved.

[0078] In a preferred embodiment, the second driving mechanism 62 includes a mounting seat 621 and a second electric telescopic rod 622. The mounting seat 621 is installed on the graphitization furnace body 20 and is located directly above the female electrical connector 41. The output shaft of the second electric telescopic rod 622 extends downward through the mounting seat 621, and the closing cover 61 is fixed on the output shaft of the second electric telescopic rod 622.

[0079] When the mother electrical connector 41 needs to be closed, the second electric telescopic rod 622 will drive the closing cover 61 to move downward until the closing cover 61 completely covers the mother electrical connector 41, forming a relatively closed space. When the power needs to be cut off, the second electric telescopic rod 622 will reversely drive the closing cover 61 to move upward to expose the mother electrical connector 41, making it convenient for the operator to perform the power-off operation.

[0080] Embodiment 2:

[0081] Please refer to Figure 1-8 This embodiment provides a mobile power transmission method for a graphitization furnace device, which is applied to the graphitization furnace device of embodiment 1; and comprises the following steps:

[0082] S100) Positioning and adjustment steps of the power transmission vehicle: preliminarily control the power transmission vehicle to move to a position corresponding to the plate body between any two first longitudinal slots 321 of the common electrode plate 32; detect the horizontal state of the power transmission vehicle, and if the uneven ground causes the vehicle body base 10 to tilt, make a small range position adjustment; if it still cannot reach the horizontal state, continue to move to a position corresponding to the plate body between the other two first longitudinal slots 321 until the power transmission vehicle reaches the horizontal state; when the power transmission vehicle reaches the horizontal state, control the electrode clamping mechanism of the power transmission vehicle to connect with the plate body to ensure stable power supply;

[0083] S200) Power supply step: the central controller 50 identifies the target graphitization furnace body 20 that needs power supply, starts the first driving mechanism 43 in the corresponding electrical connection component 40, drives the male connection terminal 42 to slide along the first longitudinal slide groove 321 to be tightly plugged with the electrical contact groove 411 of the female electrical connection member 41, and the current is transmitted to the sub-conductive electrode through the common electrode plate 32, the male connection terminal 42, the female electrical connection member 41 and the cable to supply power to the graphitization furnace body 20; ensure that the electrical connection components 40 corresponding to all non-target graphitization furnaces remain disconnected to prevent current from flowing by mistake;

[0084] S300) Power-off step: the central controller 50 identifies the graphitization furnace body 20 that needs to be powered off, starts the first driving mechanism 43 in the corresponding electrical connection assembly 40, drives the male connection terminal 42 to slide in the opposite direction along the first longitudinal sliding groove 321 until it is disengaged from the electrical contact groove 411 of the female electrical connector 41, the current is interrupted, and the graphitization furnace body 20 stops heating;

[0085] S400) Repeat the operation steps: When the power transmission vehicle completes the power supply to a target graphitization furnace, the central controller 50 identifies the next target graphitization furnace body 20 that needs power supply, and repeats the above positioning, power supply and power off steps to achieve continuous and efficient mobile power transmission.

[0086] In this way, the mobile power transmission method of the present invention allows multiple graphitization furnace bodies 20 to share a common electrode assembly 30 for power supply through the cooperation of a common electrode assembly 30 and multiple groups of electrical connection assemblies 40, which significantly reduces the cost of use and improves the flexibility of equipment layout. At the same time, the continuous power supply and power-off operation of the power transmission vehicle are realized through the automatic control of the electrical connection assembly 40, which improves work efficiency and safety. The cooperation of the first insulating support frame, the first longitudinal slide groove 321 and the driving mechanism ensures the stable transmission of current and the safety of personnel. In addition, this method is not only suitable for flat ground conditions, but also can cope with various complex and changeable ground environments. This enables the graphitization furnace device to exert its excellent performance in a wider range of application scenarios.

[0087] Specifically, S200) the power supply steps are as follows:

[0088] The first driving mechanism 43 is started, driving the male connecting terminal 42 to move along the first longitudinal sliding groove 321 toward the female electrical connecting member 41, and the male connecting terminal 42 is tightly plugged into the electrical contact groove 411 of the female electrical connecting member 41 to form an electrical connection; after the central controller 50 confirms that the electrical connection is successful, it sends a closing signal to the second driving mechanism 62; the second driving mechanism 62 receives the signal, starts and drives the closing cover 61 to move downward; during the descent of the closing cover 61, its notch 611 part is precisely aligned with and contains the male connecting terminal 42, ensuring that the male connecting terminal 42 will not fall off or shift due to the movement of the closing cover 61; the closing cover 61 completely covers the female electrical connecting member 41 to form a relatively closed space;

[0089] Specifically, the power-off steps in S300 are as follows:

[0090] When the target graphitization furnace body 20 needs to be powered off, the central controller 50 sends a power-off signal to the second drive mechanism 62; the second drive mechanism 62 receives the signal and reversely drives the closed cover 61 to move upward; during the rising process of the closed cover 61, its notch 611 gradually leaves the male connection terminal 42, and the male connection terminal 42 is still firmly held in the female electrical connector 41; the closed cover 61 completely leaves the female electrical connector 41, exposing the female electrical connector 41 and the male connection terminal 42; the central controller 50 sends a power-off signal to the first drive mechanism 43 in the corresponding electrical connection component 40, driving the male connection terminal 42 to slide in the reverse direction along the first longitudinal slide groove 321 until it is disengaged from the electrical contact groove 411 of the female electrical connector 41, the current is interrupted, and the graphitization furnace body 20 stops heating.

[0091] In this way, the mobile power transmission method of the present invention effectively prevents graphite dust, debris, etc. in the workshop from entering the interior of the female electrical connector 41 by covering the closed cover 61, reducing the risk of short circuit between the contact seat and the conductive block. The design of the notch 611 allows the male connection terminal 42 to remain in the female electrical connector 41 when the closed cover 61 is covered, and there is no need to unplug the male connection terminal 42 every time the power is turned on or off, which greatly improves the convenience of operation. Through the coordinated work of the central controller 50 and the second drive mechanism 62, the automatic control of the closed cover 61 is realized, and the intelligence level of the entire system is improved.

[0092] In this embodiment, the power transmission vehicle is provided with an electrode clamping mechanism and a busbar connection mechanism that are electrically connected to each other, wherein the electrode clamping mechanism clamps the upper and lower surfaces of the common electrode in the vertical direction. In this way, by clamping the upper and lower surfaces, it can be ensured that the electrode will not loosen or fall off due to external force during the power transmission process, thereby improving the stability of power transmission. And the electrode clamping mechanism can increase the contact area between the electrode and the power transmission vehicle, which helps to reduce contact resistance, reduce energy loss, and improve power transmission efficiency. Of course, the power transmission vehicle can also adopt a conventional structure to ensure that its electrode clamping mechanism can form an electrical connection with the common electrode.

[0093] In this embodiment, sensors are installed on the closing cover 61 and the male connection terminal 42 respectively, and the signal output ends of the above sensors are connected to the signal input ends of the central controller 50 to monitor their positions and states in real time to ensure the accuracy and reliability of the closing and power-off operations.

Any non-substantial changes and replacements made by technicians in this field on the basis of the embodiments of the present invention shall fall within the scope of protection required by the embodiments of the present invention.
