Description

Technical Field

[0001] The present invention belongs to the cross-technical field of offshore wind power foundation and submarine data center, and in particular relates to a floating submarine data center. Background Art

[0002] With the rapid development of technologies such as cloud computing, big data, and artificial intelligence, the energy consumption and land occupation of data centers have become increasingly prominent. Traditional land-based data centers not only require huge infrastructure, but also consume a lot of energy for server cooling. To this end, researchers began to explore the feasibility of deploying data centers on the seabed to take advantage of natural cooling, reduce energy consumption, and improve operation and maintenance efficiency. The concept of submarine data centers was first verified by Microsoft in its Project Natick project. The project showed that the submarine environment can provide a stable temperature and a closed environment, which helps to extend the life of equipment and reduce maintenance requirements. At the same time, submarine data centers can be deployed close to coastal cities to reduce data transmission delays and improve computing efficiency. In addition, submarine deployment can reduce the occupation of land resources by data centers and provide new solutions for sustainable data storage in the future. Although submarine data centers, as an emerging data storage and computing infrastructure, have shown great potential, especially in terms of energy consumption optimization and land resource conservation. However, their widespread application still faces challenges such as energy supply, operation and maintenance management, and environmental adaptability. First, submarine data centers require a long-term and stable energy supply, and the cost of laying and maintaining submarine cables is high. Secondly, the seabed environment is complex, including high salinity, high pressure, strong corrosion, etc., which may have adverse effects on electronic equipment and materials, so it is necessary to ensure that the server can operate stably for a long time. Moreover, because the data center is placed on the seabed, traditional manual maintenance methods are greatly limited. Once hardware failure or equipment aging occurs, the cost of replacement and maintenance is extremely high.

[0003] Prior art CN217974469U discloses a submarine data center inside an offshore wind power generation foundation, which sets the submarine data center inside a single pile foundation pile and sets refrigeration and air conditioning, using seawater as a cold source to air-condition the server cabinets and power distribution equipment. However, due to the limited internal space of the wind power pile foundation, it is usually used for cable layout, maintenance channels, etc. How to reasonably arrange data center equipment in a limited space and ensure its safety is a major challenge. In addition, the extra weight and volume of the data center may affect the stability of the wind power pile foundation, requiring structural reinforcement design.

[0004] Prior art CN117212057A discloses a floating wind turbine and submarine data center fusion device, which sets the wind turbine on a tower, and connects the tower to the submarine data center through a buoy and corresponding mooring cables, so that the submarine data center is used as the anchoring foundation of the buoy. Although this invention can effectively reduce the construction cost of floating wind turbines and submarine data centers, reduce the electricity cost of submarine data centers, and effectively improve the cooling capacity of submarine data centers. However, floating wind power will produce six-degree-of-freedom motion under the action of wind, waves, and currents. This motion may be transmitted to the data center through anchors or cables, affecting its long-term stable operation. Moreover, once the submarine data center needs to be repaired or parts replaced, it may need to be temporarily disconnected, increasing the complexity of operation and maintenance.

[0005] Regarding structural maintenance, the prior art CN117082830A discloses a submarine data center, which is provided with a separate accommodation channel, an inspection channel and a cable channel in the accommodation channel, and a heat dissipation terminal is provided on the side wall inside the accommodation channel to perform convection heat dissipation with seawater, and technicians can directly enter through the inspection channel when repairing and maintaining the data terminal, which can greatly improve the maintainability of the submarine data center and improve the efficiency and convenience of maintenance. However, on the one hand, its data center is set in the horizontal channel at the bottom of the accommodation channel, and is fixedly connected to the horizontal channel by a gravity foundation, a steel pile foundation or a suction anchor foundation, which causes the data center to have a large weight and volume. On the other hand, since the horizontal channel that accommodates the data center is fixed at the bottom, it is inevitably subject to the strong scouring effect of the bottom current, which in turn causes the loss of the marine soil under the horizontal channel, causing the instability of the structure.

DETAILED DESCRIPTION

[0021] The following is a further description of a floating submarine data center in the present invention in conjunction with the accompanying drawings in the examples of the present invention. The following examples are only used to illustrate the present invention and are not intended to limit the present invention.

[0022] See also Figure 1-2The present invention provides the following technical solutions: a floating submarine data center, which includes an offshore wind power foundation 1, a floating box 2, and a data center module 3, wherein the floating box 2 is arranged at the lower part of the offshore wind power foundation 1 and is connected to the outer side of the offshore wind power foundation 1 through an active connection component, and the data center module 3 is arranged in the floating box 2.

[0023] By setting a floating box on the seabed surface, the original vortex structure of the ocean current is effectively disrupted, the erosion of the ocean current on the seabed is reduced, the scouring effect of the ocean current on the pile foundation structure is reduced, and the service life of the pile foundation is increased. In addition, since the data center module is set on the outer side of the offshore wind power foundation and is connected to the offshore wind power foundation, the technical problem that the interior of the wind power pile foundation may not be directly in contact with open seawater and an additional cooling channel needs to be designed is overcome. The external floating submarine data center can more effectively use the seawater temperature for cooling, realizing the spontaneous heat dissipation of the data center based on low temperature and improving the cooling efficiency. In addition, the internal space of the offshore wind power foundation is limited. By reasonably arranging the data center equipment on the outside of the foundation, not only the safety of the data center is ensured, but also the influence of the extra weight and volume of the data center on the stability of the wind power pile foundation is reduced.

[0024] Among them, the offshore wind power foundation 1 is a hollow structure, and a wind turbine transmission cable 12, a battery module 13 and a data center transmission cable 16 are arranged inside the foundation. The wind turbine transmission cable 12 is connected to the battery module 13 for temporarily storing electricity, and the data center transmission cable 16 is connected to the battery module 13. A power transmission cable 17 is also arranged inside it, and the power transmission cable 17 is also connected to the battery module 13. The power transmission cable 17 is responsible for transmitting excess electricity to land.

[0025] Specifically, the electricity generated by the wind turbine when it is working is transmitted to the battery module 13 by the wind turbine transmission cable 12. The battery module 13 can adjust the fluctuation of wind power generation according to its own power, and continuously and stably output power to the data center. When the battery module 13 is fully charged, it is disconnected from the wind turbine transmission cable 12, and the excess power is transmitted to the land by the power transmission cable 17; when the battery module 13 is less than 50%, the wind turbine transmission cable 12 is actively connected until it is fully charged, reducing the risk of high-power power transmission of the wind power system causing electromagnetic interference to the electronic equipment in the data center.

[0026] The offshore wind power foundation 1 further includes a pile foundation outer door 11 and a pile foundation inner door 14, wherein the pile foundation outer door 11 is located above the sea level and is used by maintenance personnel to enter the interior of the pile foundation to perform maintenance on the pile foundation and the data center, and the pile foundation inner door 14 is used to enter the data center module 3 in the floating box 2. When maintenance is required, the maintenance personnel can enter the interior of the pile foundation through the pile foundation outer door 11 to perform maintenance on the pile foundation, and then enter the floating box 2 through the pile foundation inner door 14, and finally enter the data center module 3 for maintenance.

[0027] Based on the hollow structure setting of the offshore wind power foundation, by setting up outer and inner doors of the pile foundation, it is possible to achieve the effect of no need for personnel to dive for maintenance, effectively improving the operation and maintenance efficiency of the pile foundation structure and the submarine data center.

[0028] The floating box 2 includes a buoyancy chamber 21, a pressure chamber 22 and an anchoring structure 23. The pressure chamber 22 is a hollow structure, wherein the buoyancy chamber 21 is located at the upper part of the pressure chamber 22, and is used to offset the influence of the weight of the box on the pile foundation. One end of the anchor head of the anchoring structure 23 is fixed to the bottom of the pressure chamber 22, and the other end of the anchor body is closely connected to the seabed soil layer, and the middle is connected by an anchor chain, and the force from the anchor head is transmitted to the stable stratum through the friction resistance (or supporting resistance) between the anchor body and the surrounding soil layer. The anchoring structure 23 is used to limit the sliding range of the floating box 2.

[0029] The movable connection assembly includes a linear sleeve 15 and a sliding kit 24; the linear sleeve 15 is a solid cylindrical structure, which is installed on the outside of the offshore wind power foundation 1 and is used to be movably connected with the pressure-resistant chamber 22, so that the floating box 2 can slide up and down along the outer side of the offshore wind power foundation 1 under the action of the marine environment. Its outer surface is preferably a smooth surface to improve the smoothness of the movable connection. The sliding kit 24 includes a hollow cylindrical slider 241, which is sleeved on the outer surface of the linear sleeve 15.

[0030] The sliding kit 24 also includes a flexible waterproof cushion 242, one end of which is fixed to the outside of the offshore wind power foundation 1, and the other end is connected to the outer surface of the pressure-resistant chamber 22. After the pile foundation inner chamber door 14 is opened, the inside of the floating box 2 can be entered through the flexible waterproof cushion 242. The flexible waterproof cushion 242 is used to prevent seawater from entering the pressure-resistant chamber 22 and can move up and down with the pressure-resistant chamber 22.

[0031] The data center module 3 includes a data computing center 31, a capillary tube 32, an absorber 33, a compressor 34 and a condenser 35. The capillary tube 32 is wrapped around the outside of the data computing center 31, and a refrigerant is placed inside the capillary tube 32. One end of the absorber 33 is connected to the capillary tube 32, and the other end is connected to the compressor 34. The other end of the compressor 34 is also connected to the condenser 35. The condenser 35 is located on the outer surface of the floating box 2, and the other end of the condenser 35 is connected to the capillary tube 32. The condenser 35 is embedded in the outer shell of the pressure-resistant warehouse 22 and sealed. It is preferably a honeycomb structure that can increase the contact area with seawater. When working, the refrigerant in the capillary tube 32 absorbs the heat of the data computing center 31, flows through the absorber 33, and the compressor 34 transports the compressed refrigerant to the condenser 35. When the refrigerant flows through the condenser 35, it exchanges heat with the seawater, and the exchanged refrigerant flows back into the capillary tube 32.

[0032] In addition, more preferably, the data center module 3 also includes a drying filter 36, one end of the drying filter 36 is connected to the condenser 35, and the other end is connected to the capillary tube 32. When the refrigerant flows through the condenser 35, it exchanges heat with the seawater, and then the cooled refrigerant enters the drying filter 36 for drying to prevent moisture from forming an ice layer in the refrigeration system and clogging the pipeline. The dried refrigerant flows back to the capillary tube 32 for a new round of refrigeration.

[0033] The above embodiments describe the present invention in detail, but the contents are only preferred embodiments of the present invention and cannot be considered to limit the scope of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the present invention.
