Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of server operation and maintenance, in particular to an operation and maintenance system. BACKGROUND

[0002] In modern data centers, with the continuous improvement of computing density and the increasing demand for energy saving and emission reduction, immersion liquid cooling technology has been widely used in the cooling system of high-performance servers due to its excellent heat dissipation efficiency and system stability. Traditional immersion liquid cooling cabinets are generally single-layer structures, with servers placed horizontally, which is convenient for manual installation, maintenance and replacement. However, with the continuous growth of the number of servers and computing demand, single-layer liquid cooling cabinets have been difficult to meet the demand of high installation density, and the space utilization rate of equipment is low.

[0003] To improve the server arrangement density in unit volume, some liquid cooling systems begin to try to use multi-layer vertical arrangement structure, so that the servers are vertically placed in multiple rows (such as the liquid cooling cabinet disclosed in announcement No. CN215872521U and the multi-layer immersion liquid cooling system disclosed in announcement No. CN118647175A), thereby significantly improving the accommodation capacity and space utilization rate of the cabinet. However, multi-layer arrangement also brings new technical challenges. Since the servers are arranged vertically at different heights, the traditional manual server removal, handling and maintenance operations become extremely difficult in a multi-layer environment, with problems such as inaccessible operation height, cumbersome handling process, easy collision or misoperation, etc., greatly increasing the maintenance difficulty and safety risk.

[0004] In addition, after running in the immersion liquid cooling environment for a period of time, the servers need to be cleaned and dried regularly to ensure stable operation and prolong the service life. The existing system often lacks dedicated automatic cleaning equipment, and usually relies on manual disassembly of the servers and transfer to other areas for cleaning, which is complex and inefficient, and does not meet the current development trend of unattended and intelligent operation and maintenance of data centers. SUMMARY

[0005] In order to construct a systematic and automated operation and maintenance scheme suitable for multi-layer immersion liquid cooling environment, the present application provides an operation and maintenance system.

[0006] The operation and maintenance system provided by the present application adopts the following technical scheme:

[0007] An operation and maintenance system, comprising a multi-layer immersion liquid cooling cabinet, a lifting and rotating server transfer vehicle and a server cleaning vehicle, the multi-layer immersion liquid cooling cabinet is used for storing multiple rows of vertically arranged servers, the lifting and rotating server transfer vehicle is used for lifting to a specified height and grabbing the servers of the corresponding row, and controlling the servers to deflect and descend into the server cleaning vehicle, and the server cleaning vehicle is used for rinsing and drying the servers.

[0008] The bottom of the multi-layer immersion liquid cooling cabinet is provided with a docking control assembly, the lifting and rotating server transfer trolley is connected with the multi-layer immersion liquid cooling cabinet through the docking control assembly, the docking control assembly can control the lifting and rotating server transfer trolley to move and align with the server to be taken out, the lifting and rotating server transfer trolley is provided with a connecting positioning piece, the server cleaning vehicle is connected with the lifting and rotating server transfer trolley through the connecting positioning piece, the lifting and rotating server transfer trolley rotates to a specified angle and is just aligned with the server entrance of the server transfer trolley, and the server transfer trolley is provided with a spacing adjusting assembly, which is used to push the servers to move and arrange in the server transfer trolley at the same spacing.

[0009] By adopting the above technical scheme, the multi-layer immersion liquid cooling cabinet, the lifting and rotating server transfer trolley and the server cleaning vehicle are arranged, and an automatic operation and maintenance system suitable for a liquid cooling environment is constructed. The docking control assembly is arranged at the bottom of the liquid cooling cabinet and has a double function: on the one hand, it can guide the lifting and rotating server transfer trolley to accurately align with the target server in the current layer after longitudinal lifting is completed, so as to realize horizontal alignment; on the other hand, it is also used to realize stable docking between the multi-layer immersion liquid cooling cabinet and the lifting and rotating server transfer trolley, so as to ensure the structural stability and operation safety of the server in the process of grabbing or releasing, and effectively prevent the equipment from deviating or falling off due to poor docking.

[0010] The connecting positioning piece is used to temporarily connect the lifting and rotating server transfer trolley and the server cleaning vehicle, and after the transfer trolley rotates to a predetermined angle, it ensures that the discharge port of the transfer trolley is accurately docked with the server entrance of the cleaning vehicle. This not only helps to keep the server path centered during transfer and prevent deviation or jamming, but also facilitates the control of the rotation angle of the transfer trolley and simplifies the docking operation. After operation and maintenance are completed, the connecting positioning piece also allows the two vehicles to be quickly separated, so as to facilitate separate storage and subsequent scheduling and management.

[0011] The spacing adjusting assembly is arranged inside the server cleaning vehicle and is used to solve the problem that the servers are dropped one by one but the entrance position is fixed. Since the lifting and rotating server transfer trolley only has lifting and rotating functions and cannot move horizontally, the servers can only be dropped one by one from the same entrance. The spacing adjusting assembly can push each server forward after it falls to make room for the next server and keep the spacing between the servers consistent, so as to realize efficient and orderly arrangement and facilitate the smooth development of subsequent cleaning and drying processes.

[0012] In summary, the application establishes a highly coordinated automatic cooperation relationship among the multi-layer immersion liquid cooling cabinet, the lifting and rotating server transfer trolley and the server cleaning vehicle, and constructs a liquid cooling server automatic operation and maintenance system with high space utilization, high maintenance efficiency and strong structural coordination.

The cooling liquid is discharged into the cooling cavity through the liquid inlet pipe to cool the liquid cooling drawer. Then, the cooling liquid overflows from above the liquid cooling cavity into the return cavity and is discharged to the heat exchanger through the liquid outlet pipe.

This structure can complete accurate identification and limit control of the rotation angle without relying on complex angle measuring elements, thereby improving the automation level and adaptability of the whole system, reducing the complexity and operation and maintenance cost of the mechanism, and enhancing the flexibility, accuracy and overall system coordination during the automatic transfer and cleaning of servers.

[0068] The electric screw 288 drives the starting of a sliding plate 285 to move, so that the third rack 286 of the sliding plate 285 drives the third gear 287 to rotate, so that the third gear 287 drives the other third rack 286 to move, so that the two sliding plates 285 move away from each other, and the two sliding plates 285 are inserted into the ears on both ends of the server, and then the motor is controlled to start, so that the cantilever plate 281 and the connecting plate 284 are synchronously lifted to move the server away from the liquid cooling drawer 12, at this time, the gravity of the server makes the guide column 282 move downward and the spring is compressed. At this time, the guide column 282 is away from the second proximity switch 293, so the electric screw 288 cannot be driven, and when the second proximity switch 293 is damaged, the electric screw 288 also cannot be driven. Avoiding the risk of unstable grabbing, server falling off and other risks caused by misoperation or misdriving, significantly improving the safety of the whole grabbing process.
