Description

Technical Field

[0001] This invention relates to an immersion cavern data center based on a water diversion tunnel and its construction and operation methods, belonging to the technical field of cavern data centers. Background Technology

[0002] Cave-based data centers, protected by external mountains, possess the significant advantage of "high structural protection," effectively meeting the high security requirements of data centers and thus being gradually promoted and implemented in Guizhou and other regions. However, cave-based data centers have relatively limited advantages in "low-carbon and energy-saving" aspects, severely restricting their development. Therefore, researching and improving "low-carbon and energy-saving" features has undoubtedly become a key breakthrough direction for the sustainable development of cave-based data centers.

[0003] Chinese patent document CN119711807B discloses a cave-type data center built based on an underground river, along with its construction and operation methods. The data center includes a mountain with an underground river flowing through caves within it. Several equipment storage tunnels are located on one or both sides of the underground river within the mountain. These tunnels are connected to the caves via ramps. Each equipment storage tunnel contains equipment racks and liquid heat exchangers. A river water transport component is connected to the liquid heat exchanger, with one end of the component, away from the heat exchanger, passing through the ramp-connected tunnels and extending into the underground river. Liquid cooling is used to cool and dissipate heat from the equipment racks. This direct temperature control method significantly improves the heat dissipation and cooling effect on the IT equipment racks, while also achieving high heat exchange efficiency and reducing the data center's operating energy consumption.

[0004] However, the cooling effect of using liquid heat exchangers to cool equipment cabinets is limited, resulting in still high energy consumption for data center operation. Summary of the Invention

[0005] To address the aforementioned technical problems, this invention provides an immersion cavern data center based on a water diversion tunnel layout, along with its construction and operation methods.

[0006] This invention is achieved through the following technical solution: A submerged cavern data center based on a water diversion tunnel includes a surface water system and a water diversion tunnel. A dam is installed on the surface water system. The water diversion tunnel is located in mountain A on one side of the surface water system and downstream of the dam. The inlet of the water diversion tunnel is connected to the outlet of the dam through a surface ditch. Several sunken data troughs are arranged longitudinally on the bottom surface of the water diversion tunnel. Sealed data compartments are placed in the sunken data troughs. A track is provided longitudinally on the arch of the water diversion tunnel. A movable suspension device is installed on the track. The execution end of the movable suspension device is equipped with a data compartment grasping device.

[0007] The bottom of the surface ditch is equipped with several sedimentation basins, or the bottom elevation of the surface ditch is lower than the bottom elevation of the water inlet of the water diversion tunnel. The surface ditch is equipped with several suspended debris interception grids.

[0008] The longitudinal slope of the water diversion tunnel is 1% to 5%, and its inlet is higher than its outlet. A sluice gate is installed at the outlet of the water diversion tunnel.

[0009] The depth of the sunken data trough is 2 / 3 to 3 / 4 of the height of the sealed data compartment, and the length and width of the sunken data trough are 0.3m to 0.5m larger than the length and width of the sealed data compartment.

[0010] The bottom surface of the sunken data trough is provided with a device lifting base; Sand suction pipes are embedded in the walls on both sides of the water diversion tunnel lining, and sand pumps are installed on the sand suction pipes. The sand inlet of the sand suction pipe is located on the side wall of the sinking data trough and close to the bottom surface of the sinking data trough. The sand outlet of the sand suction pipe is located on the side wall of the lining, and a filter bag is provided on the side wall of the lining directly below the sand outlet of the sand suction pipe.

[0011] The top of the sunken data trough is hinged with two closed doors, and the bottom of the two closed doors are movably connected to the side wall of the sunken data trough through multi-stage gas springs.

[0012] The sinking data trough has a silo indicator installed on one or both sides of the water diversion tunnel sidewall.

[0013] The sealed data compartment has a cuboid structure, with a width of 0.4 to 0.6 times the width of the water diversion tunnel and a height of 0.4 to 0.6 times the height of the water diversion tunnel. The sealed data compartment is equipped with lifting lugs on its side walls.

[0014] The arch of the water diversion tunnel has two tracks arranged side by side along its longitudinal direction. One end of the track extends outside the water diversion tunnel, crosses the surface water system, and is connected to mountain B through supporting columns. Mountain B and mountain A are located on both sides of the surface water system. A centralized evacuation area is constructed on mountain B at the supporting pillars, and a transportation road is constructed on mountain B connecting the centralized evacuation area.

[0015] The bottom of the movable suspended equipment has operating platforms on both sides of the data warehouse grabbing equipment, and the operating platforms are arranged along the longitudinal direction of the water diversion tunnel.

[0016] A construction method for an immersion cavern data center based on a water diversion tunnel layout includes the following steps: Step 1: Select the terrain where the immersion cave data center is to be built, and construct a transportation road on mountain B; Step 2: Construct a dam along the transport road and intercept part of the surface water flow through the dam. Then, build a temporary construction bridge across the surface water system. The temporary construction bridge is located downstream of the dam, with one end connected to the transport road and the other end extending to the water intake of the water diversion tunnel. Step 3: Construct a water diversion tunnel using the transportation road and temporary construction bridge. Simultaneously, complete the construction of the sinking data trench during the construction of the water diversion tunnel, and install pre-embedded steel components in the arch of the water diversion tunnel. Step 4: Construct support columns on mountain B, then use pre-embedded steel components to install the track to the arch of the water diversion tunnel, and connect one end of the track to the support columns. Step 5: Install the movable suspension equipment on the track, and install the data warehouse grabbing device on the actuator of the movable suspension equipment, and then debug the equipment; Step 6: Demolish the temporary construction bridge, intercept all surface water flow by building a dam, and then divert the surface water into ditches. Step 7: Open the dam gates to release water, and divert the surface to create ditches to guide the water flow into the water diversion tunnel; Step 8: Based on the operational requirements of the submerged cavern data center, the sealed data warehouse is systematically hoisted into the sunken data tank using a combination of mobile suspension equipment and data warehouse grabbing equipment.

[0017] An operation method for an immersion cavern data center based on a water diversion tunnel layout includes the following operating modes: Water level control mode: The water inflow of the water diversion tunnel is regulated by the water-blocking dam, and the water outflow of the water diversion tunnel is regulated by the sluice gate, so that the water level in the water diversion tunnel is always higher than the sealed data chamber in the sinking data tank. Routine maintenance mode inside the tunnel: Staff members enter the water diversion tunnel by riding a mobile suspended equipment. When the mobile suspended equipment moves to a certain sinking data tank, the sealed data tank in the sinking data tank is lifted out of the water by the cooperation of the mobile suspended equipment and the data tank grabbing equipment. Then, the staff members carry out maintenance on the sealed data tank. Full-scale maintenance outside the tunnel: Using a combination of mobile suspension equipment and data warehouse grabbing equipment, the designated sealed data warehouse inside the water diversion tunnel is grabbed out of the water and hoisted to the centralized evacuation area for full-scale maintenance, or the sealed data warehouse that has been hoisted to the centralized evacuation area is transported to the designated location for full-scale maintenance by transport vehicles. Routine inspection mode of water diversion tunnel: The silt pump is started regularly to suck the silt in the sinking data tank into the filter bag through the sand suction pipe. Staff regularly ride in and out of the water diversion tunnel on a mobile suspended equipment, and during this process, pack the silt in the filter bag and transport it out of the water diversion tunnel one by one.

[0018] The beneficial effects of this invention are as follows: 1. The sealed data warehouse is picked up by a data warehouse grabbing device. A movable suspension device moves the data warehouse grabbing device and the sealed data warehouse along a track to achieve the hoisting of the sealed data warehouse. When the sealed data warehouse is aligned with a certain sunken data tank, the movable suspension device and the data warehouse grabbing device work together to place the sealed data warehouse into the sunken data tank. At the same time, water from the surface water system is introduced into the water diversion tunnel through surface diversion, which creates an immersion cooling effect on the sealed data warehouse placed in the sunken data tank. This significantly improves the cooling effect of the sealed data warehouse and greatly reduces the operating energy consumption of the data center.

[0019] 2. By coordinating the design of the water diversion tunnel with the underground data center, and utilizing the flowing water from the water diversion tunnel to continuously cool the sealed data warehouse, a new data center system is constructed that combines the dual technological advantages of the underground data center's "high structural protection" and the underwater data center's "low carbon and energy saving," resulting in significant technological advancements and practical benefits.

[0020] 3. The water diversion tunnel has the dual functions of water diversion and sealed data storage, resulting in high project utilization and significant economic benefits.

[0021] 4. The functions of the dam are twofold: firstly, to regulate the water flow into the water diversion tunnel, preventing excessively high water levels from submerging the movable suspended equipment; secondly, to store water, ensuring a continuous and sufficient supply for immersion cooling of the sealed data warehouse within the submerged data tank. Furthermore, the dam can also serve as a hydroelectric power generation dam, utilizing the water to generate electricity and provide the necessary power for the normal operation of the data center.

[0022] 5. Since the depth of the submerged data trough is 2 / 3 to 3 / 4 of the height of the sealed data chamber, after the sealed data chamber is placed inside the trough, its top protrudes beyond the trough. This facilitates the grabbing and lifting of the sealed data chamber by the grabbing equipment, and also allows for sufficient heat exchange between the sealed data chamber and the water flow. The length and width of the submerged data trough are 0.3m to 0.5m larger than the length and width of the sealed data chamber. This facilitates the placement and removal of the sealed data chamber from the trough, and also allows for sufficient contact between the sealed data chamber and the water for heat dissipation. Simultaneously, by raising the equipment's base, a gap is created between the sealed data chamber and the bottom of the submerged data trough, facilitating heat dissipation and preventing the sealed data chamber from sinking into the sediment at the bottom of the trough.

[0023] 6. When no sealed data compartment is placed in the submerged data tank, the two sealing doors close under the push of the corresponding multi-stage gas springs, thereby sealing the top opening of the submerged data tank and preventing silt and sand in the water flow from entering the submerged data tank and causing siltation.

[0024] 7. One end of the track extends outside the water diversion tunnel, crosses the surface water system, and is connected to mountain B through supporting columns, ensuring the stable installation of the track at the suspended end. At the same time, a centralized evacuation area is built on mountain B at the supporting columns, and a transport road is built on mountain B to connect with the centralized evacuation area, realizing the connection between the transport road, the centralized evacuation area, the track, and the water diversion tunnel. On the one hand, it is convenient to transport the sealed data container to the sunken data tank in the water diversion tunnel for heat dissipation and cooling. On the other hand, it is also convenient to transport the sealed data container in the sunken data tank to the centralized evacuation area or a designated location for comprehensive maintenance.

[0025] 8. The water inflow of the water diversion tunnel is regulated by the dam and the water outflow of the water diversion tunnel is regulated by the sluice gate. Under the premise that the water level in the water diversion tunnel is lower than that of the movable suspended equipment, a continuous and sufficient water flow is ensured to submerge the sealed data chamber, so that the sealed data chamber can achieve immersion heat dissipation and cooling, thereby ensuring the heat dissipation and cooling effect of the sealed data chamber.

Detailed Implementation

[0028] The technical solution of the present invention is further described below, but the scope of protection is not limited to what is described.

[0029] like Figures 1 to 5 As shown, the present invention discloses an immersion cave data center based on a water diversion tunnel, comprising a surface water system 1 and a water diversion tunnel 5. A dam 2 is provided on the surface water system 1. The water diversion tunnel 5 is located in the mountain A4 on one side of the surface water system 1 and downstream of the dam 2. The inlet of the water diversion tunnel 5 is connected to the outlet of the dam 2 through a surface diversion ditch 3. Multiple sunken data troughs 50 are arranged longitudinally on the bottom surface of the water diversion tunnel 5. Sealed data compartments 6 are placed in the sunken data troughs 50. A track 7 is provided longitudinally on the arch of the water diversion tunnel 5. A movable suspension device 8 is provided on the track 7. A data compartment grasping device 9 is provided at the execution end of the movable suspension device 8.

[0030] Specifically, data equipment is installed and fixed inside the sealed data warehouse 6.

[0031] The sealed data warehouse 6 is picked up by the data warehouse grabbing device 9. The data warehouse grabbing device 9 and the sealed data warehouse 6 are moved along the track 7 by the movable suspension device 8 to realize the hoisting of the sealed data warehouse 6. When the sealed data warehouse 6 is aligned with a certain sunken data tank 50, the sealed data warehouse 6 is placed into the sunken data tank 50 by the cooperation of the movable suspension device 8 and the data warehouse grabbing device 9. At the same time, water from the surface water system 1 is introduced into the water diversion tunnel 5 through the surface diversion ditch 3, which forms an immersion cooling for the sealed data warehouse 6 placed in the sunken data tank 50, which significantly improves the cooling effect of the sealed data warehouse 6 and greatly reduces the operating energy consumption of the data center.

[0032] The functions of the dam 2 are twofold: firstly, to regulate the water flow into the water diversion tunnel 5, preventing the water level in the tunnel from becoming too high and submerging the movable suspended equipment 8; and secondly, to store water, ensuring a continuous supply of water for immersion cooling of the sealed data chamber 6 within the submerged data tank 50. Furthermore, the dam 2 can also serve as a hydroelectric power generation dam, utilizing the water to generate electricity and provide the necessary power for the normal operation of the data center.

[0033] The bottom of the surface ditch 3 is equipped with multiple sedimentation tanks, or the bottom elevation of the surface ditch 3 is lower than the bottom elevation of the water inlet of the water diversion tunnel 5; The surface ditch 3 is equipped with multiple suspended debris interception grids.

[0034] The longitudinal slope of the water diversion tunnel 5 is 1% to 5%, and its inlet is higher than its outlet. A sluice gate 10 is provided at the outlet of the water diversion tunnel 5.

[0035] The span-to-cab ratio of the clearance section of the water diversion tunnel 5 is greater than 1; The water diversion tunnel 5 is lined, and the arch of the lining is reinforced with steel bars.

[0036] Specifically, the sedimentation tank is used to settle the silt in the water flow, so that the silt accumulates outside the water diversion tunnel 5 and is easy to clean later; or, the bottom elevation of the surface ditch 3 is lower than the bottom elevation of the water inlet of the water diversion tunnel 5, also to make the silt accumulate outside the water diversion tunnel 5 and to facilitate subsequent cleaning.

[0037] The suspended matter interception grid is used to intercept suspended matter floating on the water surface, preventing it from entering the water diversion tunnel 5 with the water flow.

[0038] The longitudinal slope of the water diversion tunnel 5 is 1% to 5%. If the longitudinal slope is too small, the water flow velocity will be too low, which will affect the heat exchange efficiency between the sealed data chamber 6 and the water flow. If the longitudinal slope is too large, it will be not conducive to the movement of the movable suspended equipment 8 along the track 7.

[0039] The span-to-span ratio of the clearance section of the water diversion tunnel 5 is greater than 1 to ensure that the water diversion tunnel 5 has sufficient clearance to ensure that the sealed data container 6 can be grabbed and lifted above the water surface for movement or maintenance.

[0040] Reinforcing steel bars are installed in the arch of the lining to improve the arch's resistance to cracking and damage, thereby ensuring that the track 7 installed in the arch of the water diversion tunnel 5 is installed firmly and to prevent cracking and deformation of the arch after subsequent loading.

[0041] A sluice gate 10 is installed at the outlet of the water diversion tunnel 5. When the flow rate of the water diversion tunnel 5 is too low, the water flow rate of the water diversion tunnel 5 is regulated by the sluice gate 10 to ensure that there is enough water in the water diversion tunnel 5 to immerse and cool the sealed data chamber 6 in the sunken data tank 50.

[0042] The depth of the sunken data trough 50 is 2 / 3 to 3 / 4 of the height of the sealed data compartment 6, and the length and width of the sunken data trough 50 are 0.3m to 0.5m larger than the length and width of the sealed data compartment 6.

[0043] The bottom surface of the sunken data trough 50 is provided with an equipment lifting base 11; Sand suction pipes 12 are embedded in the walls on both sides of the lining of the water diversion tunnel 5, and a mud pump 14 is installed on the sand suction pipe 12. The sand inlet of the sand suction pipe 12 is located on the side wall of the sinking data trough 50 and close to the bottom surface of the sinking data trough 50. The sand outlet of the sand suction pipe 12 is located on the side wall of the lining, and a filter bag 13 is provided on the side wall of the lining directly below the sand outlet of the sand suction pipe 12.

[0044] Specifically, since the depth of the submerged data trough 50 is 2 / 3 to 3 / 4 of the height of the sealed data chamber 6, after the sealed data chamber 6 is placed inside the submerged data trough 50, the top of the sealed data chamber 6 protrudes outside the submerged data trough 50. This facilitates the gripping and lifting of the sealed data chamber 6 by the data chamber gripping device 9, and also promotes sufficient heat exchange between the sealed data chamber 6 and the water flow. Based on this, the heat dissipation unit can be placed in the upper part of the inner side of the sealed data chamber 6, and the data storage unit can be placed in the lower part of the inner side of the sealed data chamber 6, which helps to improve the heat dissipation effect of the sealed data chamber 6.

[0045] The length and width of the submerged data tank 50 are 0.3m to 0.5m larger than the length and width of the sealed data compartment 6. On the one hand, this makes it easier to place the sealed data compartment 6 into the submerged data tank 50 and to remove it from the submerged data tank 50. On the other hand, it facilitates the full contact between the sealed data compartment 6 and the water for heat dissipation.

[0046] The sealed data compartment 6 is raised by the device lifting base 11, leaving a gap between it and the bottom surface of the sunken data tank 50. This facilitates heat dissipation of the sealed data compartment 6 and prevents it from sinking into the mud and sand at the bottom of the sunken data tank 50.

[0047] The sediment pump 14 is started periodically to pump the sediment in the sinking data tank 50 into the filter bag 13 through the sand suction pipe 12. The staff regularly ride the operating platform 80 on the movable suspended equipment 8 to enter and exit the water diversion tunnel 5. During this process, the sediment in the filter bag 13 is packaged and transported out of the water diversion tunnel 5 one by one to avoid the accumulation of a large amount of sediment in the sinking data tank 50, which helps to ensure the heat exchange effect between the sealed data chamber 6 and the water.

[0048] The top of the sunken data trough 50 is hinged with two closed doors 15, and the bottom of the two closed doors 15 are movably connected to the side wall of the sunken data trough 50 through multi-stage gas springs 21.

[0049] like Figure 3 As shown, when no sealed data compartment 6 is placed in the submerged data trough 50, the two closed doors 15 are closed by the push of the corresponding multi-stage gas springs 21, thereby sealing the top opening of the submerged data trough 50 and preventing the silt in the water flow from entering the submerged data trough 50 and causing siltation.

[0050] like Figure 4 As shown, during the process of the movable suspension device 8 and the data warehouse grasping device 9 lowering the sealed data warehouse 6, when the sealed data warehouse 6 contacts the closed door 15 and presses down on the closed door 15, the two closed doors 15 gradually open downwards against the force of the multi-stage gas spring 21.

[0051] like Figure 5 As shown, after the sealed data compartment 6 is placed on the equipment lifting base 11, the closed door 15 reaches its maximum opening degree under the push of the sealed data compartment 6.

[0052] After the movable suspension device 8 and the data warehouse grabbing device 9 work together to lift the sealed data warehouse 6 out of the sunken data tank 50, the two closed doors 15 close under the push of the corresponding multi-stage gas springs 21, restoring the original state. Figure 3 The state shown.

[0053] Specifically, the multi-stage gas spring 21 adopts the structure disclosed in the patent entitled "Multi-stage Gas Spring" with publication number CN205190616U, which is prior art and will not be described in detail here. A door closer or similar device can also be used to replace the multi-stage gas spring 21.

[0054] A silo indicator 16 is provided on the side wall of the water diversion tunnel 5 on one or both sides of the sunken data trough 50.

[0055] Specifically, the position indicator 16 is used to indicate the location of the sinking data tank 50, so as to quickly find the location of the sealed data tank 6 and realize the rapid grabbing, hoisting or placement of the sealed data tank 6.

[0056] The sealed data compartment 6 is a cuboid structure, with a width that is 0.4 to 0.6 times the width of the water diversion tunnel 5 and a height that is 0.4 to 0.6 times the height of the water diversion tunnel 5. The sealed data compartment 6 is equipped with lifting lugs on its side wall.

[0057] Specifically, lifting lugs are installed on the side wall of the sealed data warehouse 6 to facilitate the reliable gripping and lifting of the sealed data warehouse 6 by the data warehouse gripping device 9.

[0058] The arch of the water diversion tunnel 5 is provided with two tracks 7 arranged side by side along its longitudinal direction. One end of the track 7 extends outside the water diversion tunnel 5, crosses the surface water system 1, and is connected to the mountain B18 through the supporting column 17. The mountain B18 and the mountain A4 are distributed on both sides of the surface water system 1. A centralized evacuation area 19 is constructed on the mountain B18 at the supporting pillar 17, and a transport road 20 is constructed on the mountain B18 to connect with the centralized evacuation area 19.

[0059] Specifically, one end of track 7 extends outside the water diversion tunnel 5, crosses the surface water system 1, and is connected to the mountain B18 via supporting column 17, ensuring the stable installation of the suspended end of track 7. If the span of track 7 across the surface water system 1 is large, a beam structure similar to a bridge can be set as the installation and fixing foundation for track 7 to ensure that the load-bearing capacity of track 7 meets the requirements. At the same time, a centralized evacuation area 19 is built on mountain B18 at the supporting column 17, and a transport road 20 is built on mountain B18 to connect with the centralized evacuation area 19, realizing the connection between transport road 20, centralized evacuation area 19, track 7 and water diversion tunnel 5. On the one hand, it is convenient to transport the sealed data chamber 6 to the sunken data tank 50 in the water diversion tunnel 5 for heat dissipation and cooling. On the other hand, it is also convenient to transport the sealed data chamber 6 in the sunken data tank 50 to the centralized evacuation area 19 or a designated location for comprehensive maintenance.

[0060] Centralized evacuation area 19 serves as a parking area for transport vehicles, a hoisting area for sealed data warehouse 6, a temporary storage area, and a comprehensive maintenance area.

[0061] The bottom of the movable suspended device 8 is provided with operating platforms 80 on both sides of the data warehouse grabbing device 9, and the operating platforms 80 are arranged along the longitudinal direction of the water diversion tunnel 5.

[0062] Specifically, the bottom of the movable suspended equipment 8 is equipped with operating platforms 80 on both sides of the data warehouse grabbing equipment 9, which facilitates the use of the operating platforms 80 to carry out daily maintenance of the water diversion tunnel 5, daily maintenance of the sealed data warehouse 6, and cleaning of silt and sand in the filter bag 13.

[0063] Track 7 is the track system for the KBK crane, which is installed and fixed to the arch of the lining inside the water diversion tunnel 5 via a suspension device. The movable suspension equipment 8 includes the traveling trolley and lifting mechanism of the KBK crane. The traveling trolley runs within track 7, and the lifting mechanism is installed at the bottom of the traveling trolley. It is equipped with a chain electric hoist to drive the data warehouse grabbing equipment 9 for lifting and lowering. The KBK crane is existing technology and will not be described in detail here.

[0064] The data warehouse grabbing device 9 can realize the functions of grabbing, hoisting and releasing the sealed data warehouse 6. The data warehouse grabbing device 9 can adopt the structure disclosed in the patent with announcement number CN223372554U and patent name "Quick Positioning and Grabbing Device for Container Gantry Crane", which is the prior art and will not be described in detail here.

[0065] A construction method for an immersion cavern data center based on a water diversion tunnel layout includes the following steps: Step 1: Select the terrain for the proposed immersion cave data center and construct a transport road 20 on mountain B18.

[0066] Step Two: Construct a dam 2 along transport road 20 to impound a portion of the water flow from surface water system 1. Then, build a temporary construction bridge across surface water system 1. The temporary construction bridge is located downstream of the dam 2, with one end connected to transport road 20 and the other end extending to the intake of water diversion tunnel 5. Impounding a portion of the water flow from surface water system 1 through the dam 2 solves the water supply problem during construction.

[0067] Step 3: Construct water diversion tunnel 5 using transport road 20 and temporary construction bridge. Simultaneously, complete the construction of sinking data trench 50 during the construction of water diversion tunnel 5, and install pre-embedded steel components in the arch of water diversion tunnel 5.

[0068] Step 4: Construct support column 17 on mountain B18, then use pre-embedded steel components to install track 7 to the arch of water diversion tunnel 5, and connect one end of track 7 to support column 17.

[0069] Step 5: Install the movable suspension device 8 on track 7, and install the data warehouse grabbing device 9 on the execution end of the movable suspension device 8, and then debug the device.

[0070] Step 6: Demolish the temporary construction bridge, intercept all the water flow of surface water system 1 through the water-blocking dam 2, then construct the surface ditch 3, and complete the construction of the sedimentation basin at the bottom of the surface ditch 3.

[0071] Step 7: The dam 2 opens its gates to release water, and the surface ditch 3 directs the water flow into the water diversion tunnel 5.

[0072] Step 8: Based on the operational requirements of the submerged cave data center, the sealed data warehouse 6 is hoisted into the sunken data tank 50 in an orderly manner through the cooperation of the movable suspension equipment 8 and the data warehouse grabbing equipment 9.

[0073] An operation method for an immersion cavern data center based on a water diversion tunnel layout includes the following operating modes: Water level control mode: The inflow rate of the water diversion tunnel 5 is regulated by the dam 2, and the outflow rate of the water diversion tunnel 5 is regulated by the sluice gate 10, so that the water level in the water diversion tunnel 5 is always higher than that in the sealed data chamber 6 in the submerged data tank 50. Provided that the water level in the water diversion tunnel 5 is lower than that of the movable suspended equipment 8, a continuous and sufficient water flow is ensured to submerge the sealed data chamber 6, enabling it to achieve immersion heat dissipation and cooling, thereby guaranteeing the heat dissipation and cooling effect of the sealed data chamber 6.

[0074] Routine maintenance mode inside the tunnel: Staff members enter the water diversion tunnel 5 by riding the operating platform 80 on the movable suspended equipment 8 and use the position indicator 16 for positioning. When the movable suspended equipment 8 moves to a certain sinking data tank 50, the movable suspended equipment 8 and the data tank grabbing equipment 9 work together to grab the sealed data tank 6 in the sinking data tank 50 out of the water. Then, the staff members carry out maintenance on the sealed data tank 6.

[0075] Full-scale maintenance outside the tunnel: The designated sealed data warehouse 6 inside the water diversion tunnel 5 is lifted out of the water and transported to the centralized evacuation area 19 for full-scale maintenance by the cooperation of the movable suspension equipment 8 and the data warehouse grabbing equipment 9.
