Description

Technical Field

[0001] The present invention relates to the technical field of submarine data centers, and in particular to a submarine data center and a wind power pile driver system. Background Art

[0002] With the acceleration of the global informatization process, the demand for data processing capabilities of technologies such as cloud computing, big data, artificial intelligence and blockchain continues to rise. Traditional onshore data centers face problems such as high energy consumption, large footprint and high heat dissipation costs, while submarine data centers (UDC) are gradually emerging with their unique geographical advantages. UDC uses low-temperature deep-sea seawater for natural cooling, which not only significantly reduces energy consumption, but also reduces the occupation of land resources. It has the characteristics of green environmental protection and high efficiency. At the same time, offshore wind power generation, as a pillar industry in the field of renewable energy, has been widely used around the world, especially in the North Sea of ​​Europe and the East China Sea of ​​China, where wind power installed capacity has grown rapidly. As the core supporting structure of the wind power generation system, the offshore wind power pile driver (single pile foundation) has become the mainstream design due to its simple structure and convenient construction. However, although UDC and wind power pile drivers have made great progress in technology and application, the combination of the two is still in the exploratory stage. The existing technology has many deficiencies, which limits the realization of its synergistic potential.

[0003] First, the independent deployment mode of UDC brings challenges of high cost and low efficiency. Most existing UDC designs exist in an independent modular form. For example, the "Natick" project proposed by Microsoft encapsulates the data center in a cylindrical container and sinks it to the seabed for operation. This design requires a complex seabed anchoring system, external power supply cables, and independent cooling facilities. During the deployment process, special ships and diving equipment are required to complete the installation, and the modules need to be regularly recovered for maintenance, resulting in high construction and operation costs. In addition, the power source of independent UDC usually relies on submarine cables to transmit from the onshore power grid, which has large energy transmission losses and does not fully utilize the clean energy advantages of offshore wind power, resulting in low overall energy utilization efficiency. Although there have been attempts to integrate with wind power facilities, most of them remain in the conceptual stage and lack mature engineering solutions.

[0004] Secondly, the single function of offshore wind power pile drivers limits their potential value. As the basic structure of offshore wind power generation, wind power pile drivers usually adopt a cylindrical single pile design with a diameter of 5-8 meters, which is 20-40 meters deep in the seabed to withstand the weight of wind turbines and wind and wave loads. However, its function is limited to supporting wind turbines, and the internal hollow or solid space is not effectively utilized. Considering that offshore wind farms usually occupy a vast area and the number of pile drivers is often dozens or even hundreds, if their internal space can be developed for data processing or other functions, it will greatly improve resource utilization. However, in the existing design, the pile driver is only used as a single load-bearing component, and fails to form a synergistic effect with emerging technologies such as UDC, resulting in a waste of space and function.

[0005] Thirdly, seabed scouring and extreme weather pose a severe challenge to the stability of UDC and wind power pile drivers. When the seabed current passes through the pile driver, it will form horseshoe vortex and wake vortex around the base, resulting in an increase in local flow velocity and scouring the seabed soil. Studies have shown that the scouring depth can reach 1-2 times the pile diameter (5-10 meters), and in severe cases it may even threaten the overturning safety of the pile driver. For example, in a typical sea area with a flow velocity of 1-2 meters per second, the formation of scouring pits may reach a significant level within a few months, and in extreme weather such as typhoons (flow velocity>2 meters per second), the scouring effect is further aggravated. For independently deployed UDCs, ocean current impact and seabed turbulence also increase the risk of module displacement, and the existing anchoring system is difficult to fully resist such natural forces. In addition, the wind power pile driver and UDC are not strong enough in extreme weather, and lack a comprehensive protection design for high flow velocity and strong winds and waves, resulting in limited system reliability.

[0006] There are a few attempts to combine UDC with wind power pile drivers in the prior art. Some studies propose placing UDC modules near wind farms and using wind power for power supply, or as the 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. However, these studies do not solve the problems of space integration and scour protection, and the floating wind power pile driver is difficult to be used in shallow waters. The 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, and uses seawater as a cold source to air-condition and refrigerate the server cabinets and power distribution equipment, but in such a structure, the submarine data center cannot directly contact open seawater, and additional cooling channels need to be designed for heat exchange, and the scour protection problem cannot be solved.

[0007] In general, the existing technology lacks a systematic solution that can simultaneously achieve space optimization, efficient heat dissipation, anti-scouring capability and extreme weather adaptability of UDC and wind power pile driver. In response to the above problems, the present invention proposes an innovative solution, which aims to deeply integrate UDC and wind power pile driver through the hollow internal space of the wind power pile driver, the UDC module and the bottom directional perforation design, give full play to the synergistic advantages of the two, and improve the data processing capability, renewable energy utilization efficiency and system stability in deep sea environment.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] See also Figure 1-3 The present invention provides a technical solution: a submarine data center and wind power pile driver system, comprising a wind power pile driver 1 and a UDC module 2, wherein the wind power pile driver 1 is a hollow structure, a plurality of directional perforations are arranged at the bottom of the wind power pile driver 1, and the plurality of directional perforations are located below the sea surface 6, the plurality of directional perforations include at least one water inlet hole 3 on the upstream surface and at least one water outlet hole 4 on the downstream surface, and the UDC module 2 is arranged inside the hollow structure of the wind power pile driver 1.

[0021] The water flow is diverted through the bottom perforations, diverting about 30%-40% of the ocean current into the pile, reducing the vortex intensity on the headstream surface by 30%, dispersing the wake, and reducing the scouring depth from 5 meters to 2.5 meters, reducing the seabed scouring around the base of the pile driver and enhancing long-term stability. The bottom water flow of the seawater is used to laterally scour the UDC module, efficiently cooling the UDC module, increasing the heat exchange efficiency by 45%-50%, reducing operating energy consumption, and stabilizing the operating temperature at 18-24°C.

[0022] Furthermore, the UDC modules 2 are arranged in multiple rows, and gaps are left between each row, so that water flows through the gaps to increase heat dissipation efficiency.

[0023] Furthermore, a plurality of rows of the UDC modules 2 are vertically arranged inside the hollow structure of the wind power pile driver 1 . The vertical arrangement can increase the lateral flushing area between the UDC modules and the water flow, thereby improving the heat dissipation efficiency.

[0024] Furthermore, the wind power pile driver 1 is a hollow cylindrical structure; the UDC module 2 is a cylindrical structure. The UDC modules 2 are arranged in double rows, and each row includes 6 UDC modules 2 arranged at equal intervals, each row is 12 meters high, and the interval height between two rows is 3 meters. There are 6 directional perforations, and one directional perforation is correspondingly arranged around every 2 UDC modules 2. The multiple directional perforations include 3 water inlet holes 3 on the upstream surface and 3 water outlet holes 4 on the downstream surface.

[0025] Due to the design of directional perforations, water enters through the water inlet holes on the upstream side and exits through the water outlet holes on the downstream side. Water flows in or out from one directional perforation corresponding to each two UDC modules 2 arranged at equal intervals, further optimizing the heat dissipation and scouring reduction effects. The setting of double rows of 12 modules can make full use of the hollow space, improve computing power density, and enhance scalability.

[0026] Furthermore, the UDC module 2 is fixed to the inner wall of the wind power pile driver 1 through a steel frame 5; Furthermore, a counterweight is provided at the bottom of the UDC module 2, which can lower the center of gravity of the structure, enhance the stability of the structure, and cooperate with the bottom perforated pressure distribution design to enhance the stability of the system and resist extreme weather, and is particularly suitable for deep-sea high-flow rate environments.

[0027] In addition, the wind power pile driver 1 is preferably in the form of a single pile foundation, in which case the top of the wind power pile driver 1 is connected to a wind turbine, and the bottom of the wind power pile driver 1 is buried in the seabed 8; in addition, a floating structure setting can also be adopted, and it is only necessary to ensure that the wind power pile driver has directional perforations under the sea surface, and the purpose of the invention can also be achieved in this case.

[0028] Furthermore, the outer wall of the wind power pile driver 1 is made of corrosion-resistant steel.

[0029] Furthermore, the submarine data center and wind power pile driver system also includes a power transmission system. The wind power pile driver 1 supplies power to the UDC module through a high-voltage DC cable built into the pile wall. The cable branches are connected to each row of modules to enable wind power to directly supply power to the UDC module.

[0030] Furthermore, a filter screen 7 is provided on the outside of the directional perforation. Preferably, the filter screen 7 is made of 316L stainless steel, which is resistant to seawater corrosion. The filter screen 7 has a thickness of 2 mm and covers each directional perforation. The mesh diameter is 5 mm. The filter screen 7 is installed on the outside of the directional perforation by means of buckles. When installed, it is embedded in the bottom of the directional perforation and fixed with stainless steel buckles for easy disassembly.

[0031] By setting up a filter, impurities and particles in the seawater can be intercepted, ensuring the normal operation of the water flow cooling system and the protection of the UDC module, keeping the perforations and internal water flow channels unobstructed, ensuring that the seawater is effectively diverted and flows through the module gap, achieving efficient heat dissipation and scouring reduction effects. In addition, by using the filter as a barrier to block the entry of these impurities and particles, biofilm formation and mechanical scratches can be prevented, protecting the heat dissipation performance and structural integrity of the UDC module, thereby maintaining the stability of the long-term operation of the system. The aperture setting can effectively block common marine impurities and prevent them from entering the pile, balancing the needs of intercepting impurities and water flow. When the filter is maintained, it can be regularly disassembled and cleaned by a submersible robot or manually to remove attached impurities and ensure the perforation function.
