Description

Technical Field

[0001] This invention relates to an underwater data center based on a dam and its construction and maintenance methods, belonging to the field of underwater data center technology. Background Technology

[0002] To reduce the energy consumption of data center operations, new types of data centers, such as cave-style data centers and underwater data centers, are emerging. Among them, underwater data centers, which are completely submerged underwater, have high heat exchange efficiency and relatively outstanding energy-saving performance, and have become a new trend in data center development.

[0003] For the routine maintenance of underwater data warehouses, there are two different methods: performing maintenance directly underwater and transferring the data warehouse to land for maintenance. Underwater maintenance requires overcoming high-pressure water, which poses risks such as water ingress, increased maintenance difficulty, and significant safety hazards. Comparatively, lifting the data warehouse to the surface for maintenance is a more reliable option. However, conventional methods of salvaging underwater data warehouses using floating cranes and barges suffer from low salvage efficiency and high costs, making them unsuitable for the development needs of large-scale underwater data centers. Summary of the Invention

[0004] To address the aforementioned technical problems, this invention provides an underwater data center based on a dam and its construction and maintenance methods.

[0005] This invention is achieved through the following technical solution: An underwater data center based on a dam includes a dam, a data storage platform, and several rail-mounted suspension devices. The top of the dam is equipped with a track along its longitudinal direction, and the rail-mounted suspension devices are all mounted on the track. The data storage platform is located on the water-facing side of the dam, and several data storage units are placed on the platform.

The rotating seat passes through the top plate of the track-type electric flatcar and is rotatably connected to the top plate of the track-type electric flatcar. A driven gear is provided at the bottom of the rotating seat. The rigid suspension frame is fixedly mounted on the rotating seat, and the rope traction component is located at the top of the rigid suspension frame.

[0009] The rigid suspension frame is equipped with a counterweight block, which is located away from the rope traction component. The rope traction component includes two electric cylinders, a winch, and a roller. The two electric cylinders are arranged side by side on the top of the rigid suspension frame. Each of the two electric cylinders has a connecting block at its actuating end, and the connecting blocks on the two electric cylinders are connected by a connecting rod. The roller is rotatably mounted on the middle of the connecting rod, and a rope groove is provided on the roller along its circumference. The winch is located on the top of the rigid suspension frame and between the two electric cylinders. The end of the winch's rope is equipped with a movable threaded sleeve.

[0010] The downstream end of the top plate of the track-type electric flatbed is provided with an anchoring longitudinal beam, and multiple anchor ropes are connected to the anchoring longitudinal beam; the steering drive mechanism includes a steering drive motor, which is located on the top plate of the track-type electric flatbed. A drive gear is mounted on the output shaft of the steering drive motor, and the drive gear meshes with the driven gear.

[0011] Two longitudinal marking lines are drawn along the top surface of the dam to divide it into a driving area, a parking area, and a storage area from downstream to upstream. Multiple transverse marking lines are also drawn along the top surface of the dam to divide the storage area into multiple data storage areas. Each data storage area has an anchor assembly on the downstream side of the track and a data storage anti-fall assembly on the upstream side of the track. A data storage unit is placed on the data storage platform at a position corresponding to each data storage area. The data storage unit is connected to the data storage anti-fall assembly or rail-mounted suspension device located in its corresponding data storage area.

[0012] The anchoring assembly includes multiple anchoring rods that are anchored side by side to the top of the dam, and the anchoring rods are located inside the dam; the data warehouse anti-fall assembly includes a fixed base and a connecting rope. The fixed base is fixedly installed on the top of the dam, one end of the connecting rope is connected to the fixed base, and the other end is provided with a movable threaded sleeve.

[0013] The data warehouse includes an openable enclosed compartment and a top-mounted suspension rope. The openable enclosed compartment contains data equipment. The top of the openable enclosed compartment is a four-sided pyramidal structure that gradually decreases in shape and size from bottom to top. One end of the top-mounted suspension rope is connected to the apex of the four-sided pyramidal structure at the top of the openable enclosed compartment, and the other end is equipped with a screw. The bottom of the openable enclosed compartment has two grooves arranged side by side. On the side of the openable enclosed compartment near the dam, multiple anti-collision longitudinal beams are arranged side by side.

[0014] A construction method for an underwater data center based on a dam includes the following steps: Step 1: Carry out the construction of the water-retaining dam. During the construction process, complete the installation of the track, data warehouse storage platform, anchor bolt components and data warehouse anti-fall components, and complete the marking and zoning of the top of the water-retaining dam and the laying of the power cables and signal cables required for the data warehouse. Step 2: Install several rail-mounted suspension devices on the track; Step 3: Move the rail-mounted suspension device to the designated data warehouse storage area, and then connect multiple anchor ropes to multiple anchor base rods in the data warehouse storage area to form a reliable anchoring system, thereby completing the preparation work before lifting the rail-mounted suspension device. Step 4: Use the data warehouse transport vehicle to transport the data warehouse along the driving area to the designated parking area corresponding to the data warehouse storage area. Then, connect the data warehouse top hoisting rope to the hoisting rope of the rail-mounted suspension device, and connect the power cable and signal cable to the data warehouse. Then, manually operate the rail-mounted suspension device to slowly place the data warehouse onto the data warehouse storage platform. After separating the top hoisting rope from the suspension rope, connect the top hoisting rope to the connecting rope on the fixed base. Step 5: Separate the anchor rope from the anchor base rod, then move the rail-mounted suspension device to the next data warehouse storage area, and repeat steps 3 and 4 to complete the installation of the next data warehouse. Step 6: Repeat step 5 until all data warehouse installations are completed, thus completing the underwater data center construction.

[0015] A maintenance method for an underwater data center located on a dam includes the following steps: Step A: Move the rail-mounted suspension device to the designated data warehouse storage area, and then connect multiple anchor ropes to multiple anchor base rods in the data warehouse storage area to form a reliable anchoring system, thereby completing the preparation work before lifting the rail-mounted suspension device. Step B: Disconnect the data warehouse roof hoisting rope from the connecting rope on the fixed base, and then connect the roof hoisting rope to the hoisting rope of the rail-mounted suspension device. Manually operate the rail-mounted suspension device to slowly lift the data warehouse to the docking area downstream of the data warehouse storage area for maintenance work, or slowly lift the data warehouse onto the data warehouse transport vehicle parked in the docking area, and disconnect the data warehouse from the power cables and signal cables. Then, transport the data warehouse to a professional site for maintenance using the data warehouse transport vehicle. Step C: After the maintenance is completed, transport the data warehouse to the corresponding docking area of ​​the designated data warehouse storage area. Then, connect the data warehouse top hoisting rope to the hoisting rope of the rail-mounted suspension device, and connect the power cable and signal cable to the data warehouse. Then, manually operate the rail-mounted suspension device to slowly place the data warehouse onto the data warehouse storage platform. After separating the top hoisting rope from the suspension rope, connect the top hoisting rope to the connecting rope on the fixed base.

[0016] The beneficial effects of this invention are as follows: 1. This invention supports the data warehouse through a data warehouse storage platform and utilizes the reservoir water of the dam to cool and de-temperature the data warehouse. The data warehouse is lifted into the water for operation and out of the water for maintenance by a platform-mounted suspension device that is set on a track and can slide longitudinally along the dam. Compared with conventional underwater data centers that use floating cranes, barges and other equipment for data warehouse salvage operations, the data warehouse salvage is more efficient and less expensive, which can meet the development needs of large-scale underwater data centers.

[0017] 2. This invention can utilize hydroelectric generator sets installed inside a dam to provide the power required for the operation of the data warehouse, realizing in-situ utilization of hydroelectric power generation. Compared with conventional underwater data centers, the utilization rate of water resources is high and the data center is highly energy-efficient.

[0018] 3. This invention utilizes a dam to construct an underwater data center, significantly reducing construction costs. Simultaneously, the reservoir water of the dam cools and de-temperatures the data warehouse, greatly reducing operating costs. The design output time (i.e., full-load operating hours) of the hydroelectric generator units in a dam is generally limited. Therefore, the data warehouse provides a stable load to the hydroelectric generator units, filling in load troughs and allowing them to operate at a more economical output range for longer periods. This avoids frequent start-stops and idling, promoting the health and extending the lifespan of the generator units. Furthermore, the data warehouse can provide auxiliary services such as frequency regulation, peak shaving, and reserve capacity to the relevant power grid. Attached Figure Description

Detailed Implementation

[0021] The technical solution of the present invention is further described below, but the scope of protection is not limited to what is described.

[0022] like Figures 1 to 11 As shown, the underwater data center based on a dam according to the present invention includes a dam 1, a data storage platform 3, and several rail-mounted suspension devices 4. The top of the dam 1 is provided with a track 2 along its longitudinal direction, and the several rail-mounted suspension devices 4 are all installed on the track 2. The data storage platform 3 is located on the water-facing side of the dam 1, and several data warehouses 5 are placed on the data storage platform 3. The several data warehouses 5 are all located below the water surface of the reservoir area of ​​the dam 1, and are all electrically connected to the hydroelectric generator set inside the dam 1.

[0023] Specifically, this invention supports the data warehouse 5 through the data warehouse storage platform 3, and uses the reservoir water of the dam 1 to cool and lower the temperature of the data warehouse 5. The data warehouse 5 is lifted into the water for operation and out of the water for maintenance by a platform-rail suspension device 4 set on the track 2 and able to slide longitudinally along the dam 1. Compared with conventional underwater data centers that use floating cranes, barges and other equipment for data warehouse 5 salvage operations, the data warehouse 5 salvage is more efficient and less expensive, which can meet the development needs of large-scale underwater data centers.

[0024] This invention utilizes a hydroelectric generator set installed inside a dam 1 to provide the power required for the operation of a data warehouse 5, realizing in-situ utilization of hydroelectric power. Compared with conventional underwater data centers, this invention has a high water resource utilization rate and strong energy efficiency.

[0025] This invention utilizes a dam 1 to construct an underwater data center, significantly reducing construction costs. Simultaneously, the reservoir water of the dam 1 is used to cool and de-temperature the data warehouse 5, greatly reducing operating costs. The design output time (i.e., full-load operating hours) of the hydroelectric generator units in the dam 1 is generally limited. Therefore, the data warehouse 5 can provide a stable load for the hydroelectric generator units, filling in load troughs and allowing them to operate at a more economical output range for longer periods. This avoids frequent start-stops and idling, promoting the health and extending the lifespan of the hydroelectric generator units. Furthermore, the data warehouse 5 can provide auxiliary services such as frequency regulation, peak shaving, and reserve capacity to the relevant power grid.

[0026] The track 2 includes two parallel rails, and the track 2 is arranged close to the water-facing side of the dam 1; the data storage platform 3 is located below the normal water level of the dam 1, and the distance between the data storage platform 3 and the normal water level of the dam 1 is not less than 10m; the data storage platform 3 includes a truss platform 31, the downstream side of the truss platform 31 is fixedly connected to the water-facing side of the dam 1, the bottom of the truss platform 31 is connected to the water-facing side of the dam 1 through multiple diagonal braces 33, and a guardrail 32 is provided at the upstream edge of the truss platform 31.

The track-type electric flatcar 41 is mounted on the track 2. The bottom of the suspension mechanism 42 is rotatably connected to the track-type electric flatcar 41.

The end of the rope 4236 of the winch 4232 is provided with a movable threaded sleeve 8.

[0031] Specifically, the counterweight 425 is used to balance the lifting weight of the suspension mechanism 42. During the process of slowly placing the data pod 5 onto the data pod storage platform 3 via the rail-mounted suspension device 4, the position of the connecting rod 4235 is adjusted by controlling the extension and retraction of the two electric cylinders 4231, thereby achieving fine-tuning of the position of the data pod 5 and ensuring that the data pod 5 lands on the data pod storage platform 3.
