Description

Technical Field

[0001] This invention relates to an underwater cave-type data center based on a mountain range near water, and its construction and operation methods, belonging to the technical field of cave-type 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] Currently, a relatively effective method for reducing energy consumption is to place the data warehouse underwater for direct water cooling. However, due to the complexity of the underwater environment, the daily maintenance of underwater data warehouses has become a key technological challenge for the development of underwater data centers. There are two different approaches to the daily maintenance of underwater data warehouses: performing maintenance directly underwater and transferring the data warehouse to the surface for maintenance. Underwater maintenance solutions need to overcome the effects of high-pressure water, posing risks such as water ingress, high maintenance difficulty, and significant safety risks. In comparison, raising the data warehouse to the surface for maintenance is a more reliable solution. However, conventional methods of salvaging underwater data warehouses using floating cranes and barges suffer from low salvage efficiency and high costs, making it difficult to meet the development needs of large-scale underwater data centers.

[0004] Chinese patent document with application number CN202211556659.6 discloses an underwater data center, which is divided into fully submersible data centers and semi-submersible data centers based on the application mode. The semi-submersible data center can be entered for maintenance without the need to be raised, while the fully submersible data center can achieve efficient water surfacing through its own lifting mechanism and is easy for maintenance personnel to enter for maintenance.

[0005] However, whether it is a fully submersible data center or a semi-submersible data center, the openable manhole is exposed above the water and liquid cooling medium level during maintenance, which reduces the concealment and survivability of the underwater data center. Summary of the Invention

[0006] To address the aforementioned technical problems, this invention provides an underwater cavern-type data center based on a mountain range near water, along with its construction and operation methods.

[0007] This invention is achieved through the following technical solution: An underwater cave-style data center based on a mountain range near water includes a peninsula. One side of the peninsula is adjacent to water, and the other side has a road. Several sloping caves are constructed within the peninsula. The lower end of each sloping cave extends into the water, and the bottom of the sloping cave smoothly connects to the ground at the bottom of the water. A transport track is laid on both the bottom of the sloping cave and the ground at the bottom of the water. A train traction system is installed within the sloping cave near the road. A data train moves on the transport track and is connected to a traction rope in the train traction system.

[0008] The distance from the lower end of the slope cavern to the water surface is not less than 10m; the upper end of the slope cavern is located above the water surface, and the distance from the upper end of the slope cavern to the highest flood level of the water area is not less than 5m.

[0009] The slope cavern includes a gentle slope section and a steep slope section. The upper end of the steep slope section is connected to the lower end of the gentle slope section, and the lower end of the bottom surface of the steep slope section is smoothly connected to the ground at the bottom of the water area. The longitudinal slope of the gentle slope section is in the range of 3% to 5%, and the longitudinal length of the gentle slope section is not less than 1.5 times the length of the data train. The lower end of the gentle slope section is located above the design water level of the water area, and its distance from the design water level of the water area is not less than 2m. The gentle slope section has a maintenance passage with a width of not less than 4m on one side of the transport track. The longitudinal slope of the steep section is in the range of 20% to 40%, and the longitudinal length of the steep section is greater than n times the length of the data train, where n is the number of data trains whose transport tracks are laid on the steep section.

[0010] The transport track includes several I-shaped precast concrete monorails. The upper parts of the several I-shaped precast concrete monorails are arranged side by side in the sloping tunnel, and the lower parts are dispersed in different directions on the ground at the bottom of the water area. The end of the I-shaped precast concrete monorail away from the road is provided with a track stop. Each of the aforementioned I-shaped precast concrete monorails is equipped with a data train; The train traction system includes several traction machines, which are installed one-to-one in the sunken installation trenches inside the sloping tunnel. The data train on several I-shaped precast concrete monorails is connected one-to-one with the traction ropes of the traction machines.

[0011] The data train includes multiple frames, with adjacent frames connected by couplers. Two sets of horizontal rollers are located at the bottom of each frame, and these rollers are inserted into corresponding grooves on both sides of an I-beam precast concrete monorail. Two sets of vertical rollers are located on the inner side of the bottom of the frame, both contacting the top surface of the I-beam precast concrete monorail. A traction rope connecting block is located in the center of the inner side of the bottom of the frame, with one end of the traction rope, away from the traction machine, passing through the traction rope connecting block and equipped with an end lock. Enclosures are provided around the four edges of the top of the frame. A data storage compartment is placed on the top of the frame and is secured to the frame with clips.

[0012] The traction rope connecting block includes a rhombus-shaped block. The top of the rhombus-shaped block is connected to the vehicle frame through the connecting block. The long diagonal of the rhombus-shaped block is arranged along the length direction of the vehicle frame, and the short diagonal is arranged along the width direction of the vehicle frame. A through hole is provided on the rhombus-shaped block along the long diagonal direction. The end of the traction rope away from the traction machine is passed through the through hole on the rhombus-shaped block and then the end locking fastener is installed.

[0013] The top surface of the I-shaped precast concrete monorail is provided with multiple traction rope limiting mechanisms at intervals. The traction rope limiting mechanism includes a U-shaped base and a lever. The U-shaped base is fixed on the top surface of the I-shaped precast concrete monorail, and its U-shaped opening faces upward. One of the vertical plates of the U-shaped base has a hinged base and two spring retainers on the inner side of the U-shaped base, and the hinged base is located between the two spring retainers. The other vertical plate of the U-shaped base has a strip-shaped opening slot. The lever is used to limit the traction rope on its lower side. One end of the lever is hinged to the hinged base, and the other end passes through the strip-shaped opening slot. The two spring retainers are respectively connected to the lever through multiple sets of positioning springs.

[0014] The lever is provided with two roller limiting sleeves, and a roller is provided on the lever that rotates between the two roller limiting sleeves.

[0015] The top surface of the I-shaped precast concrete monorail is provided with multiple traction rope support wheel sets at intervals, and the traction rope support wheel sets and the traction rope limiting mechanism are arranged alternately. The traction rope support wheel set includes two support plates and a support roller. The support roller is located between the two support plates, and the central axis of the support roller is rotatably connected to the two support plates. When the traction rope support wheel assembly is installed on the transverse turning section of the I-shaped precast concrete monorail, the central axis of the support roller is arranged at an angle, and one end of the central axis of the support roller closer to the center of curvature of the transverse turning section of the I-shaped precast concrete monorail is higher than the other end; when the traction rope support wheel assembly is installed at other positions of the I-shaped precast concrete monorail, the central axis of the support roller is parallel to the top surface of the I-shaped precast concrete monorail at its location, and is arranged transversely along the I-shaped precast concrete monorail.

[0016] A protective mechanism is installed on the ground at the bottom of the water area, which encloses the I-shaped precast concrete monorail. The protective mechanism includes two deep excavation trenches and an arched protective frame. The two deep excavation trenches are arranged side by side, and an I-shaped precast concrete monorail is located between the two deep excavation trenches. Precast concrete foundations are placed in the two deep excavation trenches respectively, and the top surface of the precast concrete foundations is located above the deep excavation trenches. The two deep excavation trenches are filled with cast-in-place concrete that compacts and fixes the precast concrete foundations. The two arc-shaped ends of the arched protective frame are connected to the precast concrete foundations at the two deep excavation trenches. The arched protective frame includes multiple circumferential steel supports arranged in parallel and multiple axial connecting steel beams arranged in parallel. The two arc-shaped ends of the circumferential steel supports are connected to the precast concrete foundations at the two deep excavation trenches, and each axial connecting steel beam is connected to all the circumferential steel supports respectively. On the ground at the bottom of the water area, a hardened concrete layer is provided between two deep excavated trenches, and an I-shaped precast concrete monorail is laid on the hardened concrete layer.

[0017] A construction method for an underwater cavern-style data center located near a mountain range includes the following steps: S1. Select the peninsula and water area where the underwater cavern-style data center is to be built, and construct a road on the side of the peninsula away from the water area. S2. Material transportation is carried out using roads, and slope tunnel excavation is conducted. S3. After the slope tunnel is completed, a concrete hardening layer will be constructed on the ground at the bottom of the water area. S4. The prefabrication of the I-shaped concrete precast monorail is completed in sections on the ground in advance. Then, the traction rope limiting mechanism and traction rope support wheel set are installed on the I-shaped concrete precast monorail. Then, the I-shaped concrete precast monorail is transported to the ground inside the sloping tunnel and at the bottom of the water area, and the water surface assembly and underwater assembly of the I-shaped concrete precast monorail are completed. S5. Complete the construction of the arched protective frame on the ground and connect the two arc-shaped ends of the circumferential steel support to the precast concrete foundation. Carry out underwater trenching construction of two deep pits on the ground at the bottom of the water area. Then, put the precast concrete foundation at the bottom of the arched protective frame into the two deep pits. Next, fill the deep pits with cast-in-place concrete. S6. Install a train traction system at the end of the sloping cavern near the road, and connect the traction rope in the train traction system to the data train. Then, use the traction rope along the I-shaped precast concrete monorail to lower the data train into position, thus completing the construction of the underwater cavern-type data center.

[0018] Step S2 involves constructing a sloping tunnel using a single-head excavation method from the roadside downwards, specifically including the following steps: S21. When the unexcavated length of the slope cavern is greater than 10 meters, the slope cavern shall be excavated using water-based operations, and the groundwater that has seeped into the slope cavern shall be discharged using water pumps during the excavation process. S22. When the unexcavated length of the slope cavern is 10 meters, in order to prevent the high-pressure water in the water area from squeezing and damaging the unexcavated rock mass of the slope cavern, water is injected into the slope cavern until the water surface in the slope cavern is close to the water surface in the water area. Then, underwater operation is used to excavate the slope cavern until the slope cavern is completed.

[0019] An operational method for an underwater cave-style data center located near a mountain range includes the following working modes: Normal operating mode: The data train is parked on an underwater I-shaped precast concrete monorail, and the water in the water area is used to cool the data train. Special working mode: The train traction system pulls the data train into the steep section of the inclined tunnel, and the data train remains submerged in water, using the water in the steep section to cool the data train. Maintenance mode: When multiple I-beam precast concrete monorails are installed inside the inclined tunnel, the inclined tunnel can only meet the water discharge and maintenance needs of one data train at a time. The specific process is as follows: The designated data train is pulled to the gentle slope section of the inclined tunnel using the train traction system. Workers then use the maintenance passage to repair or maintain the data train. Alternatively, if the data train has already been pulled to the gentle slope section, the data storage compartment can be transported to a specialized location for comprehensive maintenance. After maintenance, the data storage compartment is reinstalled on the frame, and then the train traction system uses traction ropes to lower the data train along the I-shaped precast concrete monorail into the water. At this point, the maintenance work on the next data train can begin.

[0020] The beneficial effects of this invention are as follows: 1. This invention utilizes a train traction system to retrieve a data train from the water body for repair or maintenance. Compared to methods using floating cranes or barges, this method offers advantages such as higher retrieval efficiency, lower costs, no water ingress during maintenance, lower maintenance difficulty, and lower safety risks, thus meeting the development needs of large-scale underwater data centers. Furthermore, the entire maintenance process can be conducted covertly within a sloping cavern, significantly improving the concealment and survivability of underwater cavern-type data centers.

[0021] 2. The longitudinal slope of the gentle slope section is within the range of 3% to 5%, and the longitudinal slope of the steep slope section is within the range of 20% to 40%. This ensures that when the traction machine releases the traction rope, the data train can gradually move downhill under its own weight to the end of the I-shaped precast concrete monorail away from the road. Considering both the construction cost of the sloping tunnel and the climbing ability of the data train, the longitudinal slope of the steep slope section is set within the range of 20% to 40%. If the longitudinal slope is too small, it will increase the length of the sloping tunnel, increasing the construction cost; if the longitudinal slope is too large, it will increase the difficulty of climbing for the data train. The longitudinal length of the steep slope section is greater than n times the length of the data train, where n is the number of data trains laid on the transport track of the steep slope section. This ensures that when the underwater tunnel-type data center adopts a special working mode, all data trains can be staggered and parked within the steep slope section of the sloping tunnel.

[0022] 3. Compared with data trains with a power system, this invention separates the traction machine from the data train and places it above the designed water level in the water area, thus avoiding the risk of damage to the power system caused by the data train being submerged underwater for a long time.

[0023] 4. Typically, only one precast I-beam concrete monorail is laid in a sloping tunnel. However, the technical solution provided by this invention allows for the laying of two, three, or even more precast I-beam concrete monorails in a single sloping tunnel. When the transport track includes multiple precast I-beam concrete monorails, the lower parts of all the precast I-beam concrete monorails are distributed in different directions on the ground at the bottom of the water body. It is only necessary to ensure that the distance between adjacent precast I-beam concrete monorails in the sloping tunnel meets the passage requirements of a data train. This minimizes the width of the sloping tunnel, or, given a fixed width, maximizes the number of precast I-beam concrete monorails and data trains, thereby significantly increasing the number of data trains included in the underwater tunnel-type data center and reducing the investment in underwater tunnel-type data center projects.

[0024] 5. The traction rope is limited by the traction rope limiting mechanism to prevent the traction rope from lifting under tension, ensuring that the traction machine can normally pull the data train longitudinally along the I-shaped precast concrete monorail and can normally lower the data train longitudinally along the I-shaped precast concrete monorail.

[0025] 6. The support rollers have V-shaped grooves along their circumference. These grooves support the traction rope, preventing it from contacting the top surface of the I-beam precast concrete monorail and causing rapid wear. For the support rollers installed on the transverse turning sections of the I-beam precast concrete monorail, in addition to preventing rapid wear from contact with the top surface of the monorail, they also guide the traction rope, ensuring it is laid along the contour of the I-beam precast concrete monorail.

[0026] 7. When the unexcavated length of the slope tunnel exceeds 10 meters, there is a thick layer of rock separating the slope tunnel from the water area. Therefore, while strengthening drainage operations, the slope tunnel should be excavated using water-based operations to ensure construction efficiency.

[0027] 8. When using a special working mode, the data train is positioned off-center on the steep slope of the underwater cavern, which can prevent the data train from being threatened by fire when the underwater cavern data center is attacked, ensuring that the data train can operate continuously and stably, and significantly improving the survivability of the underwater cavern data center.

Detailed Implementation

[0030] The technical solution of the present invention is further described below, but the scope of protection is not limited to what is described.

[0031] like Figures 1 to 17 As shown, the underwater cave-type data center based on a mountain range near water, as described in this invention, includes a peninsula 1. One side of the peninsula 1 is adjacent to a water area 2, and the other side is provided with a road 3. Several sloping caves 4 are constructed within the peninsula 1. The lower end of each sloping cave 4 extends into the water body of the water area 2, and the bottom surface of the sloping cave 4 is smoothly connected to the ground at the bottom of the water area 2. A transport track 5 is laid on both the bottom surface of the sloping cave 4 and the ground at the bottom of the water area 2. A train traction system 7 is installed inside the sloping cave 4 near the road 3. A data train 6 is moved on the transport track 5, and the data train 6 is connected to the traction rope 72 in the train traction system 7.

[0032] Specifically, the data train 6 includes multiple train chassis and multiple data devices. Any two adjacent data train chassis are connected by a coupler. The multiple data devices are installed one-to-one on the multiple train chassis, and the outer casing of the data devices is sealed and waterproof.

[0033] A cable is used as the inner core, and steel strands are braided on the outside of the cable to form a traction rope 72. The cable is used to transmit power to the data train 6, and the steel strands are used to bear the traction force.

[0034] The data train 6 is parked on the transport track 5 at the bottom of the water area 2 and continues to work normally. The water in the water area 2 is used to cool the data train 6, realizing the low-carbon and energy-saving operation of the underwater cave-type data center.

[0035] When maintenance is required on the data train 6, the data train 6 is towed to a position near the upper end of the slope tunnel 4 by the train traction system 7. At this time, the data train 6 is above the water surface of the water area 2, and the staff can carry out maintenance or repair on the data train 6 inside the slope tunnel 4 without underwater operations; or the data train 6 can be transported to a professional site for comprehensive inspection.

[0036] In other words, this invention, by retrieving the data train 6 from the water body 2 using the train traction system 7, and then performing repairs or maintenance on the data train 6, offers advantages over methods using floating cranes, barges, or other equipment. These advantages include higher retrieval efficiency, lower costs, no water ingress during maintenance, lower maintenance difficulty, and lower safety risks, thus meeting the development needs of large-scale underwater data centers. Furthermore, the entire maintenance process for the data train 6 can be carried out covertly within the sloping cavern 4, significantly improving the concealment and survivability of the underwater cavern-type data center.

[0037] The distance from the lower end of the slope cavern 4 to the water surface of the water area 2 is not less than 10m; the upper end of the slope cavern 4 is located above the water surface of the water area 2, and the distance from the upper end of the slope cavern 4 to the highest flood level of the water area 2 is not less than 5m.

[0038] The slope cavern 4 includes a gentle slope section 41 and a steep slope section 42. The upper end of the steep slope section 42 is connected to the lower end of the gentle slope section 41, and the lower end of the bottom surface of the steep slope section 42 is smoothly connected to the ground at the bottom of the water area 2. The longitudinal slope of the gentle slope section 41 is in the range of 3% to 5%, and the longitudinal length of the gentle slope section 41 is not less than 1.5 times the length of the data train 6. The lower end of the gentle slope section 41 is located above the design water level of the water area 2, and the distance from it to the design water level of the water area 2 is not less than 2m. The gentle slope section 41 has a maintenance passage 411 with a width of not less than 4m on one side of the transport track 5. The longitudinal slope of the steep slope section 42 is in the range of 20% to 40%, and the longitudinal length of the steep slope section 42 is greater than n times the length of the data train 6, where n is the number of data trains 6 laid on the transport track 5 of the steep slope section 42.

[0039] Specifically, the lower end of the gentle slope section 41 is located above the design water level of water area 2, and the distance between it and the design water level of water area 2 is not less than 2m. This prevents water from water area 2 from flowing into the gentle slope section 41, thereby preventing the traction machine 71 within the gentle slope section 41 from being submerged, or the data train 6 being maintained within the gentle slope section 41. This ensures that the traction machine 71 can work normally and that the maintenance work on the data train 6 can be carried out normally, and also provides a guarantee for the safety of maintenance personnel within the gentle slope section 41. In addition, compared with the data train 6 with a power system, this invention separates the traction machine 71 from the data train 6 and places it above the design water level of water area 2, avoiding the risk of damage to the power system due to long-term submersion underwater with the data train 6.

[0040] The longitudinal length of the steep slope section 42 is greater than n times the length of the data train 6, where n is the number of data trains 6 laid on the transport track 5 of the steep slope section 42, ensuring that when the underwater cavern-type data center adopts a special working mode, all data trains 6 can be staggered and parked in the steep slope section 42 of the sloping cavern.

[0041] The longitudinal slope of the gentle slope section 41 is within the range of 3% to 5%, and the longitudinal slope of the steep slope section 42 is within the range of 20% to 40%. This allows the data train 6 to gradually move downwards under its own weight to the end of the I-shaped precast concrete monorail away from the road 3 when the traction machine 71 releases the traction rope 72. After comprehensively considering the construction cost of the inclined tunnel 4 and the climbing conditions of the data train 6, the longitudinal slope of the steep slope section 42 is set within the range of 20% to 40%. If the longitudinal slope is too small, it will lead to an increase in the length of the inclined tunnel 4, increasing the construction cost of the inclined tunnel 4. If the longitudinal slope is too large, it will increase the difficulty of the data train 6 climbing the slope.

[0042] A maintenance passage 411 with a width of not less than 4m is set up in the gentle slope section 41 to provide sufficient activity space for staff to carry out maintenance on the data train 6 in the gentle slope section 41. In addition, the maintenance passage 411 can also provide an external transportation channel for the data storage bin 66 of the data train 6.

[0043] The transport track 5 includes several I-shaped precast concrete monorails. The upper parts of the several I-shaped precast concrete monorails are arranged side by side in the sloping tunnel 4, and the lower parts are dispersed in different directions on the ground at the bottom of the water area 2. The end of the I-shaped precast concrete monorail away from the road 3 is provided with a track stop 51. Each of the aforementioned I-shaped precast concrete monorails is equipped with a data train 6; The train traction system 7 includes several traction machines 71, which are installed one-to-one in the sunken installation trough 43 inside the inclined tunnel 4. The data train 6 on several I-shaped precast concrete monorails is connected one-to-one with the traction ropes 72 of the several traction machines 71.

[0044] Specifically, the sunken installation groove 43 is located at the upper end of the I-shaped precast concrete monorail.

[0045] Normally, only one I-beam precast concrete monorail is laid in a sloping tunnel 4. However, the technical solution provided by this invention can lay two, three, or even more I-beam precast concrete monorails in a sloping tunnel 4. When the transport track 5 includes multiple I-beam precast concrete monorails, the lower parts of all the I-beam precast concrete monorails are distributed in different directions on the ground at the bottom of the water area 2. It is only necessary to ensure that the distance between adjacent I-beam precast concrete monorails in the sloping tunnel 4 meets the passage requirements of a data train 6, so as to minimize the width of the sloping tunnel 4, or, with a fixed width of the sloping tunnel 4, to achieve the goal of arranging as many I-beam precast concrete monorails and data trains 6 as possible, thereby significantly increasing the number of data trains 6 included in the underwater tunnel data center, and thus reducing the investment in the underwater tunnel data center project.

[0046] A track stop 51 is installed at the end of the I-shaped precast concrete monorail away from the road 3 to prevent the data train 6 from derailing from the I-shaped precast concrete monorail.

[0047] The traction machine 71 can be a winch, and the number of traction machines 71 is consistent with the number of I-shaped precast concrete monorails in the inclined tunnel 4. The traction machine 71 is installed in the sunken installation groove 43 and further anchored by anchor bolts to ensure that the traction machine 71 does not shift during operation.

[0048] The data train 6 includes multiple frames 61, and adjacent frames 61 are connected by couplers. The bottom of the frame 61 is provided with two sets of horizontal rollers 62, and the two sets of horizontal rollers 62 are inserted into the grooves on both sides of the I-shaped precast concrete monorail. The inner side of the bottom of the frame 61 is provided with two sets of vertical rollers 63, and the two sets of vertical rollers 63 are in contact with the top surface of the I-shaped precast concrete monorail. The inner side of the bottom of the frame 61 is provided with a traction rope connecting block 64. The end of the traction rope 72 away from the traction machine 71 passes through the traction rope connecting block 64, and the end is provided with an end lock 73. The top of the frame 61 is provided with a barrier 65 around its four edges. The top of the frame 61 is provided with a data storage compartment 66, and the data storage compartment 66 is snapped to the frame 61 by a buckle.

[0049] Specifically, the data train 6 includes multiple frames 61, and adjacent frames 61 are connected by couplers, which helps to improve the data train 6's ability to pass through I-shaped precast concrete monorails.

[0050] Two sets of vertical rollers 63 are installed on the inner side of the bottom of the frame 61, and both sets of vertical rollers 63 are in contact with the top surface of the I-shaped precast concrete monorail to ensure that the data train 6 rolls in contact with the I-shaped precast concrete monorail. Two sets of horizontal rollers 62 are installed at the bottom of the frame 61, and the corresponding parts of the two sets of horizontal rollers 62 are inserted into the grooves on both sides of the I-shaped precast concrete monorail, thereby confining the data train 6 on the I-shaped precast concrete monorail and preventing the data train 6 from overturning under the action of external forces such as water flow impact.

[0051] The traction rope connecting block 64 is the force-bearing structure for the traction rope 72 to transmit traction force to the data train 6. An end locking fastener 73 is provided on the end of the traction rope 72 away from the traction machine 71 to ensure a reliable connection between the traction rope 72 and the traction rope connecting block 64.

[0052] The top of the frame 61 is equipped with barriers 65 on all four sides. Specifically, three of the edges are set as fixed barriers, and the edge near the maintenance passage 411 is set as a movable barrier. The movable barrier is hinged to the frame 61 and is respectively snapped into its two adjacent fixed barriers by buckles.

[0053] The traction rope connecting block 64 includes a rhombus-shaped block 641. The top of the rhombus-shaped block 641 is connected to the frame 61 through a connecting block 642. The long diagonal of the rhombus-shaped block 641 is arranged along the length direction of the frame 61, and the short diagonal is arranged along the width direction of the frame 61. A through hole is provided on the rhombus-shaped block 641 along the long diagonal direction. The end of the traction rope 72 away from the traction machine 71 is passed through the through hole on the rhombus-shaped block 641 and then the end locking fastener 73 is installed.

[0054] Specifically, the four sides of the rhombus block 641 are used to pry open the lever 104 to improve the smoothness of the prying process.

[0055] The top surface of the I-shaped precast concrete monorail is provided with multiple traction rope limiting mechanisms 10 at intervals. The traction rope limiting mechanism 10 includes a U-shaped base 101 and a lever 104. The U-shaped base 101 is fixed on the top surface of the I-shaped precast concrete monorail, and its U-shaped opening faces upward. On one of the vertical plates of the U-shaped base 101, there is a hinge base 103 and two spring retainers 105 on the inner side of the U-shaped base 101. The hinge base 103 is located between the two spring retainers 105. The other vertical plate of the U-shaped base 101 has a strip-shaped opening slot 102. The lever 104 is used to limit the traction rope 72 on its lower side. One end of the lever 104 is hinged to the hinge base 103, and the other end passes through the strip-shaped opening slot 102. The two spring retainers 105 are respectively connected to the lever 104 through multiple sets of positioning springs 106.

[0056] Specifically, the traction rope 72 is limited by the traction rope limiting mechanism 10 to prevent it from lifting under tension, ensuring that the traction machine 71 can normally pull the data train 6 longitudinally along the I-shaped precast concrete monorail and lower the data train 6 longitudinally along the I-shaped precast concrete monorail. Figure 8 and Figure 9 As shown, in the initial state, the lever 104 is in the centered position under the spring force of the positioning springs 106 on both sides; as Figure 10 As shown, when the data train 6 moves downward along the I-shaped precast concrete monorail to a certain traction rope limiting mechanism 10, the rhombus block 641 contacts the lever 104 and pushes the lever 104 to rotate downward around the hinge axis. When the rhombus block 641 disengages from the lever 104, the lever 104 quickly swings back to the center position under the spring force of the positioning springs 106 on both sides, thereby restricting the traction rope 72 to the lower side of the lever 104 and preventing the traction rope 72 from lifting up under the tension. When the data train 6 moves upward along the I-shaped precast concrete monorail to a certain traction rope limiting mechanism 10, the rhombus block 641 contacts the lever 104 and pushes the lever 104 to rotate upward around the hinge axis. When the rhombus block 641 disengages from the lever 104, the lever 104 quickly swings back to the center position under the spring force of the positioning springs 106 on both sides, and releases the restriction on the traction rope 72.

[0057] like Figure 12 and Figure 13As shown, for the longitudinal straight section of the I-shaped precast concrete monorail, the traction rope limiting mechanism 10 can be positioned slightly to the left or right of the top surface of the I-shaped precast concrete monorail. For the lateral turning section of the I-shaped precast concrete monorail, when the I-shaped precast concrete monorail turns left, the traction rope limiting mechanism 10 is positioned slightly to the left of the top surface of the I-shaped precast concrete monorail, such as... Figure 12 As shown; when the I-shaped precast concrete monorail turns right, the traction rope limiting mechanism 10 is positioned slightly to the right of the top surface of the I-shaped precast concrete monorail, as shown. Figure 13 As shown.

[0058] The lever 104 is provided with two roller limiting sleeves 108, and a roller 107 is provided on the lever 104 that rotates between the two roller limiting sleeves 108.

[0059] Specifically, the roller 107 is axially limited by two roller limiting sleeves 108, and the friction between the traction rope 72 and the lever 104 is reduced by the roller 107, thus slowing down the wear rate of the lever 104 and the traction rope 72.

[0060] The top surface of the I-shaped precast concrete monorail is provided with multiple traction rope support wheel sets 11 at intervals, and the traction rope support wheel sets 11 and the traction rope limiting mechanism 10 are arranged alternately. The traction rope support wheel set 11 includes two support plates 111 and support rollers 112. The support rollers 112 are located between the two support plates 111, and the central axis of the support rollers 112 is rotatably connected to the two support plates 111. Specifically, the support roller 112 has a V-shaped groove along its circumference. The support roller 112 supports the traction rope 72, preventing the traction rope 72 from contacting the top surface of the I-shaped precast concrete monorail and causing it to wear out quickly.

[0061] When the traction rope support wheel assembly 11 is installed on the transverse turning section of the I-shaped precast concrete monorail, the central axis of the support roller 112 is arranged at an angle, and one end of the central axis of the support roller 112 near the center of curvature of the transverse turning section of the I-shaped precast concrete monorail is higher than the other end; when the traction rope support wheel assembly 11 is installed at other positions of the I-shaped precast concrete monorail, the central axis of the support roller 112 is parallel to the top surface of the I-shaped precast concrete monorail at its location, and is arranged transversely along the I-shaped precast concrete monorail.

[0062] Specifically, such as Figure 1 and Figure 15 As shown, when the traction rope support wheel assembly 11 is installed on the right-turning section of the I-shaped precast concrete monorail, the left end of the central shaft of the support roller 112 is lower than the right end; as Figure 1 and Figure 16As shown, when the traction rope support wheel assembly 11 is installed on the left-turning section of the I-shaped precast concrete monorail, the left end of the central axis of the support roller 112 is higher than the right end. For the support roller 112 installed on the transverse turning section of the I-shaped precast concrete monorail, in addition to preventing the traction rope 72 from contacting the top surface of the I-shaped precast concrete monorail and causing rapid wear, it also guides the traction rope 72, thus ensuring that the traction rope 72 is laid along the alignment of the I-shaped precast concrete monorail.

[0063] A protective mechanism 8 is installed on the ground at the bottom of the water area 2, which encloses the I-shaped precast concrete monorail. The protective mechanism 8 includes two deep excavation trenches 81 and an arched protective frame 82. The two deep excavation trenches 81 are arranged side by side, and an I-shaped precast concrete monorail is located between the two deep excavation trenches 81. Precast concrete foundations 83 are placed in the two deep excavation trenches 81 respectively, and the top surface of the precast concrete foundations 83 is located above the deep excavation trenches 81. The two deep excavation trenches 81 are filled with cast-in-place concrete 84 that compacts and fixes the precast concrete foundations 83. The two arc-shaped ends of the arched protective frame 82 are connected to the precast concrete foundations 83 at the two deep excavation trenches 81. The arched protective frame 82 includes multiple circumferential steel supports 821 arranged in parallel and multiple axial connecting steel beams 822 arranged in parallel. The two arc-shaped ends of the circumferential steel supports 821 are connected to the precast concrete foundations 83 at the two deep excavation trenches 81, and each axial connecting steel beam 822 is connected to all the circumferential steel supports 821 respectively. A hardened concrete layer 9 is provided on the ground at the bottom of the water area 2 between two deep excavated trenches 81, and an I-shaped precast concrete monorail is laid on the hardened concrete layer 9.

[0064] Specifically, when the data train 6 is parked on the I-shaped precast concrete monorail at the bottom of the water area 2, the protective mechanism 8 envelops the data train 6 on its inner side to form a protective barrier, preventing sinking objects in the water area 2 from colliding with the data train 6. The arched protective frame 82 adopts a frame structure to ensure that the water flow in the water area 2 can fully contact the data train 6 for fluid heat exchange, thereby ensuring the cooling effect of the water in the water area 2 on the data train 6.

[0065] A construction method for an underwater cavern-style data center located near a mountain range includes the following steps: S1. Select the peninsula 1 and water area 2 where the underwater cavern-style data center is to be built, and construct road 3 on the side of peninsula 1 away from water area 2; S2. Material transportation is carried out using road 3, and the slope tunnel 4 is excavated. S3. After the slope tunnel 4 is completed, a concrete hardening layer 9 will be constructed on the ground at the bottom of the water area 2. S4. The prefabrication of the I-shaped concrete precast monorail is completed in sections on the ground in advance. Then, the traction rope limiting mechanism 10 and the traction rope support wheel group 11 are installed on the I-shaped concrete precast monorail. Then, the I-shaped concrete precast monorail is transported to the ground inside the slope tunnel 4 and at the bottom of the water area 2, and the water surface assembly and underwater assembly of the I-shaped concrete precast monorail are completed. S5. Complete the construction of the arched protective frame 82 on the ground and connect the two arc-shaped ends of the circumferential steel support 821 to the precast concrete foundation 83. Carry out underwater trenching construction of two deep trenches 81 on the ground at the bottom of the water area 2. Then, place the precast concrete foundation 83 at the bottom of the arched protective frame 82 into the two deep trenches 81. Next, fill the deep trenches 81 with cast-in-place concrete 84. S6. Install a train traction system 7 at one end of the slope cavern 4 near the road 3, and connect the traction rope 72 in the train traction system 7 to the data train 6. Then, use the traction rope 72 along the I-shaped precast concrete monorail to lower the data train 6 into place through the train traction system 7, thus completing the construction of the underwater cavern data center.

[0066] In step S2, the inclined tunnel 4 is constructed by excavating downwards from the side of road 3 in a single-heading manner, specifically including the following steps: S21. When the unexcavated length of the slope cavern 4 is greater than 10 meters, the slope cavern 4 shall be excavated using the water-based operation method, and the groundwater that has seeped into the slope cavern 4 shall be discharged using a water pump during the excavation process.

[0067] Specifically, when the unexcavated length of the slope tunnel 4 is greater than 10 meters, there is a thick layer of rock separating the slope tunnel 4 from the water area 2. Therefore, while strengthening drainage operations, the slope tunnel 4 is excavated using water-based operations to ensure construction efficiency.

[0068] S22. When the unexcavated length of the slope cave 4 is 10 meters, in order to prevent the high-pressure water of the water area 2 from squeezing and damaging the unexcavated rock mass of the slope cave 4, water is injected into the slope cave 4 until the water surface inside the slope cave 4 is close to the water surface of the water area 2. Then, underwater operation is used to excavate the slope cave 4 until the slope cave 4 is completed.

[0069] Specifically, when the unexcavated length of the slope cavern 4 is 10 meters, the rock layer between the slope cavern 4 and the water area 2 is relatively thin. Therefore, it is necessary to prevent the high-pressure water from the water area 2 from squeezing and damaging the unexcavated rock mass of the slope cavern 4. Thus, water is injected into the slope cavern 4 to prevent the high-pressure water from the water area 2 from squeezing and damaging the unexcavated rock mass of the slope cavern 4.

[0070] An operational method for an underwater cave-style data center located near a mountain range includes the following working modes: Normal operating mode: Data Train 6 is parked on an underwater I-shaped precast concrete monorail, and the water in Water Area 2 is used to cool Data Train 6, achieving low-carbon and energy-saving operation of the underwater cavern-type data center.

[0071] Special working mode: The train traction system 7 pulls the data train 6 into the steep slope section 42 of the inclined tunnel 4, and the data train 6 remains submerged in water, using the water in the steep slope section 42 to cool down the data train 6.

[0072] Specifically, when using a special working mode, the data train 6 is positioned in a staggered manner within the steep slope section 42 of the sloping cave 4. This avoids threatening the safety of the data train 6 when the underwater cave data center is attacked by fire, ensuring that the data train 6 can operate continuously and stably, and significantly improving the survivability of the underwater cave data center.

[0073] Maintenance mode: When multiple I-beam precast concrete monorails are installed inside the inclined tunnel 4, the inclined tunnel 4 can only meet the water discharge maintenance needs of one data train 6 at a time. The specific process is as follows: The designated data train 6 is pulled to the gentle slope section 41 of the inclined tunnel 4 by the train traction system 7. The staff can then use the maintenance passage 411 to repair or maintain the data train 6. Alternatively, if the data train 6 has been pulled to the gentle slope section 41, the data storage compartment 66 can be transported to a professional site for comprehensive maintenance. After the maintenance is completed, the data storage compartment 66 is put back onto the frame 61. Then, the train traction system 7 uses the traction rope 72 to lower the data train 6 into the water along the I-shaped precast concrete monorail. At this point, the maintenance work of the next data train 6 can begin.
