Description

Technical Field

[0001] The present invention relates to the technical field of operation and maintenance equipment, and particularly to an operation and maintenance vehicle. Background Art

[0002] At present, due to the fact that direct immersion liquid cooling technology can achieve better heat dissipation effects than traditional air cooling technology, it is increasingly favored by users. Direct immersion liquid cooling refers to directly immersing electronic devices in insulating coolant, and components inside the electronic devices directly conduct heat exchange with the coolant.

[0003] However, when it is necessary to repair electronic devices, a special crane is required to take out the electronic devices from the liquid cooling cabinet, then place the electronic devices in the operation and maintenance vehicle and send them into the operation and maintenance room for operation and maintenance. After the electronic devices complete testing in the operation and maintenance room, a crane is still needed to put the electronic devices back into the operation and maintenance vehicle. After the operation and maintenance vehicle transports the electronic devices to the side of the liquid cooling cabinet, with the cooperation of the crane, the electronic devices are put back into the liquid cooling cabinet again. In this way, the whole process has many operation steps, takes a long time, and has low work efficiency. Summary of the Invention

[0062] To make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings. Apparently, the described embodiments are only a part rather than all of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0063] The present invention provides an operation and maintenance vehicle to solve the problems in the prior art that during the operation and maintenance of electronic devices, the whole process has many operation steps, takes a long time, and has low work efficiency.

[0064] Refer to Figures 1 to 2 、 Figures 4 to 7 simultaneously, the operation and maintenance vehicle includes a vehicle body 10, a maintenance mechanism 20 and a lifting mechanism 30 arranged on the vehicle body 10;

[0065] The vehicle body 10 has a first chamber 101 and a second chamber 102 that are open at the top and do not communicate with each other. The first chamber 101 is used to accommodate the electronic device 40 and dry the electronic device 40; the second chamber 102 is used to accommodate the coolant and the electronic device 40, and the electronic device 40 is immersed in the coolant;

[0066] The maintenance mechanism 20 is used to maintain the electronic device 40 in the second chamber 102;

[0067] The lifting mechanism 30 is used to transfer the electronic device 40 between the vehicle body 10 and the liquid-cooled cabinet 50 accommodating the electronic device 40.

[0068] Specifically, the vehicle body 10 has a hollow chamber with an open top. A partition can be arranged in the hollow chamber to form the first chamber 101 and the second chamber 102, and the first chamber 101 and the second chamber 102 do not communicate with each other. Among them, the first chamber 101 does not contain coolant. The first chamber 101 is used for drying the electronic device 40. After drying or during the drying process, the staff can perform simple maintenance on the electronic device 40. During this process, the electronic device 40 is in a shutdown state; a support beam is arranged at the top of the first chamber 101, and the electronic device 40 can be suspended on the support beam through lugs, or a hollow support frame is arranged inside the first chamber 101, and the electronic device 40 is placed on the support frame; during the drying process, the coolant in the electronic device 40 drips to the bottom of the first chamber 101. A drain valve and a liquid receiving tank are arranged at the bottom of the first chamber 101. The coolant collected at the bottom of the first chamber 101 can be discharged from the first chamber 101 through the drain valve, and the recovery of the coolant can be realized through the liquid receiving tank.

[0069] The space of the first chamber 101 can accommodate a plurality of electronic devices 40 , so that the plurality of electronic devices 40 can be dried and repaired at the same time, thereby improving the repair efficiency.

[0070] The second chamber 102 contains coolant. By immersing the electronic device 40 in the coolant, the coolant can cool the electronic device 40 that needs to be repaired online, thereby preventing the electronic device 40 from overheating when running in the air without a fan. A liquid inlet and a liquid outlet can also be set on the side wall of the second chamber 102 to realize the circulation of the coolant.

[0071] A maintenance mechanism 20 is provided on the vehicle body 10, and the maintenance mechanism 20 can perform maintenance on the electronic equipment 40 in the second chamber 102. The maintenance mechanism 20 includes but is not limited to a display 21, a keyboard, a mouse, etc. During the maintenance process, the electronic equipment 40 is in operation, and the heat generated by the electronic equipment 40 during the maintenance process can be dissipated into the coolant, thereby avoiding the phenomenon of local overtemperature of the electronic equipment 40. Since the maintenance mechanism 20 is integrated on the vehicle body 10, and the vehicle body 10 is provided with a second chamber 102 for holding coolant, there is no need to transport the electronic equipment 40 to a special operation and maintenance room, and it can be completed directly on the operation and maintenance vehicle in the computer room. Moreover, the lifting mechanism 30 for transferring the electronic equipment 40 between the vehicle body 10 and the liquid cooling cabinet 50 is also integrated on the vehicle body 10. In this way, there is no need to use a special crane for lifting. The lifting mechanism 30 moves with the vehicle body 10, and the two can be moved synchronously to the vicinity of different liquid cooling cabinets 50, which is more convenient to use.

[0072] For ordinary maintenance vehicles, the function is relatively simple, and it only undertakes the function of transporting the electronic equipment 40 to the maintenance room. The maintenance of the electronic equipment 40 needs to be completed in the maintenance room, and the back and forth transportation affects efficiency. The improved maintenance vehicle integrates the maintenance mechanism 20 on the vehicle body 10, and the vehicle body 10 is provided with a second chamber 102 for holding coolant, so that the electronic equipment 40 can be kept in operation and immersed in the coolant for maintenance without worrying about the electronic equipment 40 running without fan heat dissipation causing the local temperature of the components inside the electronic equipment 40 to be too high, and the cumbersome process of transporting the equipment back and forth is avoided; ordinary maintenance vehicles need to cooperate with traditional cranes. During use, the maintenance vehicle and the crane need to be moved to different liquid cooling cabinets 50, which is inconvenient to operate. The improved maintenance vehicle integrates the lifting mechanism 30 on the vehicle body 10, and the lifting mechanism 30 moves with the vehicle body 10, and can be synchronously moved to different liquid cooling cabinets 50, which is more convenient to use.

[0073] In order to more clearly understand the operation and maintenance vehicle provided by the embodiment of the present invention, the specific structure of the operation and maintenance vehicle is now described in detail.

[0074] In some embodiments,Figure 3 As shown, a first socket assembly 60a and a second socket assembly 60b are provided on the vehicle body 10. Among them, the first socket assembly 60a is used to connect to the electronic device 40 in the second chamber 102, and the second socket assembly 60b is used to connect to the maintenance mechanism 20. And a first wire harness (not shown) is provided between the first socket assembly 60a and the second socket assembly 60b, and the first wire harness is located inside the vehicle body 10.

[0075] Specifically, the first socket assembly 60a and the second socket assembly 60b may include multiple sockets, and these sockets include but are not limited to USB sockets, VGA sockets, etc. The first socket assembly 60a and the second socket assembly 60b are connected by the first wire harness, and the first wire harness can be hidden inside the vehicle body 10. In this way, the length of the exposed wire harness is reduced, the influence on the movement of the electronic device 40 caused by the too long wire harness is avoided, and the appearance of the vehicle body 10 is also neater.

[0076] When it is necessary to repair the electronic device 40 in the second chamber 102, the connection wire harness on the electronic device 40 can be connected to the corresponding socket in the first socket assembly 60a, and the connection wire harness on the maintenance mechanism 20 can be connected to the corresponding socket in the second socket assembly 60b, so as to realize the connection between the electronic device 40 and the maintenance mechanism 20.

[0077] As an example, the first socket assembly 60a can be arranged close to the second chamber 102, such as Figure 3 shown, the first socket assembly 60a is arranged on the top surface of the side wall of the second chamber 102. In this way, after the electronic device 40 is placed in the second chamber 102, the connection wire harness led out from the electronic device 40 extends as close as possible to the side wall of the second chamber 102. After the connection wire harness emerges from the coolant, it can be very conveniently inserted into the corresponding socket in the first socket assembly 60a, and it will not interfere with the up and down movement of other electronic devices 40. At the same time, since the first socket assembly 60a is relatively close to the electronic device 40, the length of the connection wire harness between the electronic device 40 and the first socket assembly 60a can be shortened; similarly, the second socket assembly 60b can also be arranged close to the maintenance mechanism 20, so that it is convenient to plug and unplug, and the length of the connection wire harness between the second socket assembly 60b and the maintenance mechanism 20 can be shortened.

[0078] Continue to refer to Figure 3 , a third socket assembly 60c and a fourth socket assembly 60d are also provided on the vehicle body 10. Among them, the third socket assembly 60c is used to connect to an external line, and the fourth socket assembly 60d is used to connect to the electronic device 40 in the second chamber 102. And a second wire harness (not shown) is provided between the third socket assembly 60c and the fourth socket assembly 60d, and the second wire harness is located inside the vehicle body 10.

[0079] In specific settings, the third socket component 60c and the fourth socket component 60d may include multiple sockets, such as but not limited to power sockets, network sockets, etc. For example, the third socket component 60c and the fourth socket component 60d include a power socket and a network socket. Correspondingly, the external wiring harness includes a power line and a network cable. When it is necessary to repair the electronic device 40, the power line can be connected to the power socket, and the network cable can be connected to the network socket. At the same time, the connection harness on the electronic device 40 is connected to the corresponding socket in the fourth socket component 60d, so as to provide a power signal and a network signal for the electronic device 40.

[0080] A second wiring harness is provided between the third socket component 60c and the fourth socket component 60d, and the second wiring harness can be hidden inside the vehicle body 10. In this way, the length of the exposed wiring harness is shortened, which avoids the influence on the up and down movement of the electronic device 40 when the wiring harness is too long, and also makes the appearance of the vehicle body 10 neater.

[0081] As an example, as Figure 3 shown, the third socket component 60c is arranged on the top surface of the side wall of the vehicle body 10 and close to the end. In this way, it is convenient to connect with the external wiring harness. Among them, the external wiring harness can be a wiring harness led out from a socket in the computer room, or an external wiring harness of the electronic device 40. For the latter, external wiring harnesses are connected to the electronic devices 40 in the liquid-cooled cabinet 50, such as power lines and network cables. When the electronic device 40 is taken out of the liquid-cooled cabinet 50 and placed inside the vehicle body 10 of the operation and maintenance vehicle, the power line of the electronic device 40 can be directly used for power supply, and the network cable of the electronic device 40 can be used for networking, without the need to take power or network from other sockets separately, reducing the trouble of being unable to operate due to the lack of nearby socket positions and the winding of long power strips.

[0082] The fourth socket component 60d is arranged close to the second chamber 102, and the fourth socket component 60d is arranged on the top surface of the side wall of the second chamber 102. In this way, when the electronic device 40 is placed in the second chamber 102, the connection harness led out from the electronic device 40 can extend as close as possible to the side wall of the second chamber 102. After the connection harness emerges from the coolant, it can be very conveniently inserted into the corresponding socket in the fourth socket component 60d, without interfering with the up and down movement of other electronic devices 40. At the same time, since the fourth socket component 60d is close to the electronic device 40, the length of the connection harness between the electronic device 40 and the fourth socket component 60d can be shortened.

[0083] In specific settings, as Figure 3 shown, the fourth socket component 60d and the first socket component 60a are integrated on a circuit board.

[0084] In summary, the operation and maintenance vehicle is provided with socket assemblies that are respectively adapted to the external wiring harness, the electronic device 40, and the maintenance mechanism 20, enabling online maintenance of the electronic device 40, and the routing of various wiring harnesses is clear and concealed, without interfering with the up and down movement of the electronic device 40.

[0085] As an example, as Figure 1 、 Figure 2 shown, the maintenance mechanism 20 includes a display 21 and a keyboard and mouse assembly 22, and the display 21 and the keyboard and mouse assembly 22 are arranged close to the second socket assembly 60b. During use, the display 21 and the keyboard and mouse assembly 22 are connected to the corresponding sockets in the second socket assembly 60b through a wiring harness. The insertion and removal of the wiring harness are very convenient. After connection, the staff can use the display 21 and the keyboard and mouse assembly 22 to perform online maintenance on the electronic device 40.

[0086] As an example, as Figure 1 shown, the vehicle body 10 includes a first side wall 1001. The first side wall 1001 is provided with a receiving groove 1003 and a bracket 1004. The bracket 1004 is used to support the keyboard and mouse assembly 22, and the bracket 1004 is rotatably connected to the first side wall 1001. When the bracket 1004 rotates above the receiving groove 1003 and covers the receiving groove 1003, the keyboard and mouse assembly 22 is received in the receiving groove 1003.

[0087] When there is no need to maintain the electronic device 40, the bracket 1004 covers the receiving groove 1003, and the keyboard and mouse assembly 22 is received in the receiving groove 1003. In this way, space can be saved and the keyboard and mouse assembly 22 can be protected; when online maintenance of the electronic device 40 is required, the bracket 1004 rotates relative to the receiving groove 1003 to a horizontal position and forms a tabletop support for the keyboard and mouse assembly 22, facilitating the staff to use the keyboard and mouse assembly 22.

[0088] Specifically, hooks (not labeled) are provided at both ends of the bracket 1004, and limit holes are provided on the side wall of the receiving groove 1003. When the bracket 1004 rotates relative to the receiving groove 1003 to a horizontal position, the end of the hook away from the bracket 1004 is hooked on the edge of the limit hole, restricting the bracket 1004 from further rotating and keeping the bracket 1004 in the horizontal position; when the bracket 1004 rotates in the opposite direction relative to the receiving groove 1003, the end of the hook disengages from the edge of the limit hole.

[0089] As an example, as Figure 3 shown, the second socket assembly 60b is arranged on the side wall of the receiving groove 1003. By arranging the second socket assembly 60b on the side wall of the receiving groove 1003, it is convenient for the connection or disconnection of the connecting wiring harness on the keyboard and mouse assembly 22 and the second socket assembly 60b.

[0090] As an example, as Figure 1 、Figure 2 As shown, the vehicle body 10 further includes a second side wall 1002, and the second side wall 1002 is perpendicular to the first side wall 1001;

[0091] A swivel arm 23 is provided between the display 21 and the second side wall 1002. The swivel arm 23 is used to set the display screen of the display 21 perpendicular to the second side wall 1002 and parallel to the first side wall 1001, and the swivel arm 23 is also used to set the display screen of the display 21 parallel to the second side wall 1002.

[0092] Based on the above, the keyboard and mouse assembly 22 is arranged on the first side wall 1001 of the vehicle body 10, and the display 21 is arranged on the second side wall 1002 of the vehicle body 10. The first side wall 1001 is perpendicular to the second side wall 1002. During use, the staff faces the first side wall 1001, so that the keyboard and mouse can be very conveniently operated. By setting the display screen of the display 21 perpendicular to the second side wall 1002 and parallel to the first side wall 1001, the maintenance personnel can face the display screen of the display 21, which is convenient for viewing the content displayed on the display screen; after the maintenance is completed, rotate the swivel arm 23 to set the display screen of the display 21 parallel to the second side wall 1002 to save the overall occupied space.

[0093] In some embodiments, a liquid receiving plate 70 is further provided on the vehicle body 10. One end of the liquid receiving plate 70 extends outside the vehicle body 10 and is used to overlap on the liquid cooling cabinet 50, and the liquid receiving plate 70 and the maintenance mechanism 20 are respectively arranged on different sides of the vehicle body 10.

[0094] As Figure 6 shown, the operation and maintenance vehicle is arranged side by side with the liquid cooling cabinet 50. When the electronic device 40 is transferred between the liquid cooling cabinet 50 and the vehicle body 10, the liquid receiving plate 70 can receive the coolant dripping from the electronic device 40 and make the coolant flow into the chamber of the vehicle body 10 or the chamber of the liquid cooling cabinet 50, avoiding the waste of coolant and the pollution of the internal environment of the computer room caused by the coolant dripping onto the ground; in addition, since the electronic device 40 needs to pass above the liquid receiving plate 70, the liquid receiving plate 70 and the maintenance mechanism 20 are arranged on different sides of the vehicle body 10, which can prevent the electronic device 40 from colliding with the maintenance mechanism 20 during movement.

[0095] In some embodiments, as Figure 7 shown, the lifting mechanism 30 includes a lifting platform 31, a lifting drive device 32, a hanging device 33, and a translation drive device 34. Among them, the lifting drive device 32 can drive the lifting platform 31 to perform lifting movement in the vertical direction. The lifting platform 31 includes a cantilever 311. The cantilever 311 is located above the first chamber and the second chamber. The translation drive device 34 and the hanging device 33 are both arranged on the cantilever 311, as Figure 4 、Figure 6 As shown, the translation drive device 34 can drive the hanging device 33 to extend horizontally above the chamber of the liquid cooling cabinet 50, or retract above the chamber of the operation and maintenance vehicle. The electronic device 40 can be suspended on the hanging device 33 and follow the hanging device 33 to achieve lifting and translation movements, so as to be transferred between the liquid cooling cabinet 50 and the operation and maintenance vehicle.

[0096] Compared with the traditional gantry crane, on the one hand, the lifting mechanism 30 is integrated on the vehicle body 10 of the operation and maintenance vehicle and can move synchronously with the operation and maintenance vehicle without separate movement. On the other hand, the lifting mechanism 30 structurally includes a lifting platform 31 that can lift in the vertical direction, and the lifting platform 31 adopts a cantilever 311 structure. The hanging device 33 is arranged on the cantilever 311 and can extend horizontally above the chamber of the liquid cooling cabinet 50 or retract above the chamber of the operation and maintenance vehicle under the drive of the translation drive device 34. The hanging device 33 and the translation drive device 34 only occupy the space above the chamber and are not easily bumped into other devices. The entire lifting mechanism 30 has a simple structure, is convenient to use, does not need to work across the liquid cooling cabinet 50 or the operation and maintenance vehicle, and occupies a small space.

[0097] Optionally, a first limit sensor 80a and a second limit sensor 80b are arranged on the vehicle body 10. The first limit sensor 80a and the second limit sensor 80b are arranged at intervals in the vertical direction and are used to detect the vertical position of the lifting platform.

[0098] The operation and maintenance vehicle further includes a control mechanism, which is used to control the lifting drive device to stop driving the lifting platform 31 to lift or lower in the vertical direction if any one of the first limit sensor 80a or the second limit sensor 80b is triggered.

[0099] Specifically, as Figure 8 shown, the first limit sensor 80a and the second limit sensor 80b are arranged on the side wall surface of the vehicle body. When the lifting platform 31 rises to the first vertical position, the first limit sensor 80a will be triggered. When the lifting platform 31 descends to the second vertical position, the second limit sensor 80b will be triggered. As long as any one of the first limit sensor 80a and the second limit sensor 80b is triggered, the lifting drive device will stop driving the lifting platform to continue moving. The first limit sensor 80a and the second limit sensor 80b limit the maximum stroke of the lifting platform 31 in the vertical direction, ensuring the safety during the hoisting process and improving the applicability of the lifting mechanism 30 in the computer room.

[0100] Optionally, a third limit sensor 80c and a fourth limit sensor 80d are arranged on the cantilever 311. The third limit sensor 80c and the fourth limit sensor 80d are arranged at intervals in the horizontal direction and are used to detect the horizontal position of the hanging device 33.

[0101] The maintenance vehicle further includes a control mechanism, which is configured to control the translation drive device 34 to stop driving the hanging device 33 from extending or retracting horizontally if any one of the third limit sensor 80c and the fourth limit sensor 80d is triggered.

[0102] Specifically, as Figure 7 shown, the third limit sensor 80c and the fourth limit sensor 80d are arranged on the cantilever 311. When the hanging device 33 moves horizontally to the first horizontal position, the third limit sensor 80c will be triggered. When the hanging device 33 moves horizontally to the second horizontal position, the fourth limit sensor 80d will be triggered. As long as any one of the third limit sensor 80c and the fourth limit sensor 80d is triggered, the translation drive device 34 will stop driving the hanging device 33 from continuing to move. The third limit sensor 80c and the fourth limit sensor 80d limit the maximum stroke of the hanging device 33 in the horizontal direction, ensuring the safety during the hoisting process and improving the applicability of the hoisting mechanism 30 in the computer room.

[0103] When specifically arranged, as Figure 1 、 Figure 2 shown, the vehicle body 10 includes a first frame 11 and a second frame 12 arranged side by side, where:

[0104] The first chamber 101 and the second chamber 102 are arranged in the first frame 11;

[0105] A power supply device is arranged in the second frame 12, and the power supply device is at least used to supply power to the lifting drive device 32 and the translation drive device 34;

[0106] A gap 13 is provided between the first frame 11 and the second frame 12. The lifting platform 31 is arranged on the side of the second frame 12 facing the first frame 11, and the lifting platform 31 is configured to descend into the gap 13 or ascend from the gap 13 under the action of the lifting drive device 32.

[0107] Continuing to refer to Figure 1 、 Figure 2 , according to different functions, the vehicle body 10 of the maintenance vehicle can be divided into two parts, namely the first frame 11 and the second frame 12. The first frame 11 has a chamber for accommodating the electronic device 40. The second frame 12 and the first frame 11 are arranged front and back, and there is a gap 13. The lifting platform 31 is arranged on the side of the second frame 12 facing the first frame 11, and the lifting platform 31 is configured to descend into the gap 13 or ascend from the gap 13 under the action of the lifting drive device 32. This gap 13 provides an avoidance space for the lifting movement of the lifting platform 31.

[0108] The second housing 12 also has a chamber which can be used to accommodate a power supply device. The power supply device can at least supply electrical energy to the lifting drive device 32 and the translation drive device 34. Specifically, the power supply device can be a rechargeable battery. In this way, each area of the vehicle body 10 of the maintenance vehicle is clearly divided, with a compact structure and high space utilization rate.

[0109] As Figure 2 , Figure 7 shown, the lifting platform 31 further includes a fixing frame 312 which is arranged vertically and fixedly connected to the cantilever 311. The fixing frame 312 is located in the gap and connected to the lifting drive device 32. The structure of the lifting platform 31 is relatively simple, including a vertically arranged fixing frame 312 and a horizontally arranged cantilever 311 which are fixedly connected to form an L-shaped structure. On the one hand, the fixing frame 312 can provide support for the cantilever 311, and on the other hand, it is connected to the lifting drive device 32, so as to drive the cantilever 311 to move up and down in the vertical direction under the drive of the lifting drive device 32. The fixing frame 312 is located on one side of the chamber and will not interfere with the chamber during the movement.

[0110] As Figure 8 shown, the lifting drive device 32 includes a ball screw 321 and a first drive motor. The ball screw 321 and the first drive motor are arranged in the second housing 12, and a long hole 1201 is provided on the side wall of the second housing 12. The nut of the ball screw is located in the long hole 1201; the lifting platform 31 is fixedly connected to the nut on the ball screw 321.

[0111] The ball screw 321 has high precision and good stability. By driving the lifting platform 31 to move up and down through the ball screw 321, the stability of the electronic device 40 can be maintained and the shaking of the electronic device 40 can be reduced. During specific installation, the ball screw 321 and the first drive motor can be arranged in the second housing 12, so that the space inside the second housing 12 can be reasonably utilized. Moreover, the second housing 12 also plays a role in protecting and shielding the ball screw 321 and the first drive motor, improving the appearance effect of the maintenance vehicle.

[0112] As Figure 9 shown, in order to ensure that the lifting platform 31 moves in the vertical direction, at least one guiding column 90 is further provided on the side wall of the second housing 12. The guiding column 90 is arranged on the same side as the lifting platform 31; a connecting seat 100 is arranged between the lifting platform 31 and the ball screw 321, and the connecting seat 100 is slidably connected to the guiding column 90.

[0113] Specifically, two guiding columns 90 are provided on the side wall of the second housing 12. These two guiding columns 90 are slidably connected to the connecting seat 100, and the connecting seat 100 is fixedly connected to the nut on the ball screw 321 and the lifting table 31 respectively. Under the action of the first driving motor, the ball screw 321 will drive the connecting seat 100 to slide along the guiding column 90, thereby driving the lifting table 31 to move up and down.

[0114] In some embodiments, as Figure 7 shown, the translation driving device 34 includes a fixed rail 341, a sliding rail 342 and a driving unit 343. The fixed rail 341 is fixedly connected to the lifting table 31, the sliding rail 342 is slidably connected to the fixed rail 341, and the hanging device 33 is arranged on the sliding rail 342; the driving unit 343 is used to drive the sliding rail 342 to slide along the fixed rail 341 so that the hanging device 33 extends or retracts.

[0115] Specifically, the extending directions of the fixed rail 341 and the sliding rail 342 are the arranging directions of the electronic devices 40 in the operation and maintenance vehicle. The hanging device 33 is arranged on the sliding rail 342. When the sliding rail 342 slides relative to the fixed rail 341, the hanging device 33 can extend above the chamber of the liquid cooling cabinet 50, so that the electronic device 40 in the liquid cooling cabinet 50 can be lifted, or the electronic device 40 can be put back into the liquid cooling cabinet 50. Similarly, the hanging device 33 can also retract above the chamber of the operation and maintenance vehicle, so that the electronic device 40 in the operation and maintenance vehicle can be lifted, or the electronic device 40 can be put back into the operation and maintenance vehicle. After the fixed rail 341 and the sliding rail 342 are assembled, they can bear the weight of the electronic device 40. Especially when the sliding rail 342 extends above the liquid cooling cabinet 50, it is necessary to ensure that the fixed rail 341 and the sliding rail 342 can still provide stable support.

[0116] Optionally, the hanging device 33 is slidably connected to the sliding rail 342. A plurality of positioning holes are arranged along the length direction of the sliding rail 342, and the hanging device 33 is detachably fixed in the positioning holes through pins. That is to say, the position of the hanging device 33 on the sliding rail 342 is variable. In this way, during use, in addition to driving the sliding rail 342 to slide along the fixed rail 341 under the action of the second driving unit 343 so that the hanging device 33 moves above the specified electronic device 40, the position of the hanging device 33 can also be adjusted so that the hanging device 33 moves above the specified electronic device 40, improving the flexibility of use.

[0117] Optionally, the driving unit 343 includes a gear, a rack, and a second driving motor. The gear is connected to the output shaft of the second driving motor, and the gear meshes with the rack. The rack is fixed on the sliding rail 342. When the second driving motor rotates, the gear drives the rack to move horizontally, and the force of the movement of the rack drives the sliding rail 342 to move smoothly. In this way, through the transmission of the gear and the rack, the movement of the electronic device 40 is relatively stable, reducing the shaking of the electronic device 40.

[0118] In addition, in order to facilitate the movement of the maintenance vehicle, a plurality of rollers (not labeled) are provided at the bottom of the maintenance vehicle. One or more of the rollers can be electric wheels, and the driving device for driving the electric wheels to rotate can be arranged in the second frame 12 of the vehicle body 10. In this way, it will be easier to move the maintenance vehicle, and the physical strength of the staff can be saved.

[0119] As can be seen from the above description, in the embodiment of the present invention, the improved maintenance vehicle has more abundant functions than the ordinary maintenance vehicle. First, a second chamber for containing coolant is provided on the vehicle body of the improved maintenance vehicle, so that the electronic device can be maintained in an operating state and immersed in the coolant for maintenance. Second, the maintenance mechanism of the improved maintenance vehicle is integrated on the vehicle body, and the maintenance of the electronic device can be directly completed in the computer room, avoiding the cumbersome process of transporting back and forth between the computer room and the maintenance room. Third, the lifting mechanism of the improved maintenance vehicle is integrated on the vehicle body, and the lifting mechanism moves with the vehicle body and can be synchronously moved to the vicinity of different liquid-cooled cabinets, making it more convenient to use.

[0120] Obviously, those skilled in the art can make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalent technologies, the present invention is also intended to include these modifications and variations.
