Description

Technical Field

[0001] The present invention relates to the technical field of submarine data centers, and in particular to a modularized hemispherical pressure-resistant cabin structure for a submarine data center. Background Art

[0002] Traditional submarine cabins (such as cylindrical ones) have stress concentration problems. Long-term pressure can easily lead to fatigue cracking of welds. In addition, the capacity of a single cabin is limited. It is difficult to balance sealing and structural stability when connecting multiple cabins. The modular expansion problem has not been solved. The surface of the cut cabin is easily affected by the attachment of marine organisms, which reduces the life of the equipment.

[0003] The insufficient structural strength and poor expansion flexibility faced by submarine data center cabins in the high-pressure environment of the seabed are technical problems that need to be solved. Summary of the Invention

[0004] The present invention provides a modular submarine data center hemispherical pressure-resistant cabin structure, comprising a main cabin, an internal support assembly, and a connection assembly;

[0005] There are multiple main cabins, each of which is a fully hemispherical single-shell structure surrounded by a shell. The inner cavity of each main cabin is pre-installed with relevant functional units. A plurality of annular interfaces are formed on the cabin wall of each main cabin, and a sealing groove with a double trapezoidal cross-section is formed on the inner wall of the annular interface. For two docked main cabins, the middle hole between the two docked annular interfaces is connected to provide a cable installation space;

[0006] There are multiple internal support assemblies corresponding to the cabin bodies one by one, and each internal support assembly includes multiple semicircular arc-shaped support frames, which are distributed inside the corresponding main cabin body and fixed to the inner wall of the main cabin body;

[0007] The connecting component is an electromagnetic locking component, including a controller, a position sensor, a lock slot mechanism, a lock tongue mechanism and an electromagnetic coil. The lock slot mechanism includes a lock slot mounting shell and a lock slot configured on the lock slot mounting shell. The lock tongue mechanism includes a lock tongue mounting shell and a lock tongue configured on the lock tongue mounting shell. The lock tongue is provided with an automatic reset spring. The electromagnetic coil and the position sensor are electrically connected to the controller. The electromagnetic coil surrounds the outer ring of the lock tongue. Through holes are formed on the lock slot mounting shell and the lock tongue mounting shell. For the two main cabins to be connected, the lock slot mechanism is configured on one of the main cabins. The lock tongue mechanism is arranged on the annular interface of the other main cabin body, and the through hole on the lock slot mounting shell is connected with the middle hole of the annular interface. The controller energizes the electromagnetic coil based on the connection instruction. After the electromagnetic coil is energized, it drives the lock tongue to embed into the lock slot docking with it. The position sensor detects the distance between the lock tongue and the lock slot in real time and returns the detection information to the controller. Based on the detection information, after the lock tongue is embedded in the predetermined position in the lock slot, it is determined that the two main cabin bodies are locked and docked.

[0008] Preferably, the sealing groove is filled with two layers of sealing rings, a silicone sealing ring on the inner layer and a polytetrafluoroethylene sealing ring on the outer layer. The silicone sealing ring and the polytetrafluoroethylene sealing ring cooperate to provide a double sealing mechanism.

The power transmission between the main cabins adopts magnetic resonance coupling technology, and the data transmission adopts optical fiber and sonar dual-channel redundant design.

[0017] The modular hemispherical pressure-resistant cabin structure of the submarine data center of the present invention has the following advantages:

[0018] 1. Improved Mechanical Performance: The hemispherical cabin evenly disperses deep-sea pressure. At a water depth of 30 meters, the maximum stress is 42% lower than that of a cylindrical cabin, extending fatigue life to 30 years. The bionic honeycomb support frame increases the cabin's load-bearing capacity by 30% while reducing material usage by 15%, achieving a combination of lightweight and high strength.

[0019] 2. Optimized deployment and operation efficiency: The modular electromagnetic locking device reduces the time required to connect multiple pods to 2 hours per pod, supports automated operation of underwater robots, and reduces the deployment cycle from the traditional 6 months to 30 days.

DETAILED DESCRIPTION

[0032] The present invention will be further described below with reference to the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it. However, the embodiments given are not intended to limit the present invention. Unless there is a conflict, the embodiments of the present invention and the technical features in the embodiments may be combined with each other.

[0033] An embodiment of the present invention provides a modular hemispherical pressure-resistant cabin structure for a submarine data center, which is used to solve the technical problems of insufficient structural strength and poor expansion flexibility faced by the submarine data center cabin in a high-pressure submarine environment.

[0034] Example:

[0035] The present invention provides a modular submarine data center hemispherical pressure-resistant cabin structure, which includes a main cabin 1, an internal support assembly 2 and a connection assembly 4.

[0036] There are multiple main cabins 1, and each main cabin 1 is a fully hemispherical single-shell structure surrounded by a shell. The inner cavity of each main cabin 1 is pre-installed with relevant functional units. A plurality of annular interfaces 3 are formed on the cabin wall of each main cabin 1, and a sealing groove with a double trapezoidal cross-section is formed on the inner wall of the annular interface 3. For two docked main cabins 1, the middle hole between the two docked annular interfaces 3 is connected to provide cable installation space.

[0037] In this embodiment, the fully hemispherical monocoque is integrally formed from a high-strength, corrosion-resistant material (high-strength titanium alloy). The curvature radius of the hull is 4.5m and the thickness is 80mm. The inner wall of the main hull 1 is a biomimetic honeycomb pattern, and the outer surface of the main hull 1 is coated with an anti-biological coating. This coating uses a graphene-titanium dioxide composite coating to inhibit the attachment of marine organisms through photocatalysis.

[0038] The functional units in the main cabin 1 include servers, cooling units, solid-state batteries, fiber optic slip rings and sonar communication modules, etc. The main cabin 1 is filled with inert gas.

[0039] Specifically, the computing power cabin: the hemispherical main cabin accommodates the server cluster, and a single cabin supports a power load of 20-40kW.

[0040] Energy storage cabin: an integrated solid-state battery pack that supplies power to the computing cabin (101) through wireless power transmission technology.

[0041] Communication relay cabin: built-in fiber optic slip ring and sonar communication module to achieve inter-cabin data interconnection and sea surface communication.

[0042] The sealing groove is filled with two layers of sealing rings: an inner silicone ring and an outer PTFE ring. The inner silicone ring has a Shore hardness of 60±5 and a compressibility of 30% (in pre-compressed state), while the outer PTFE ring, reinforced with 15% glass fiber and possessing a compressive strength of ≥25MPa, fills the inner and outer sealing grooves, respectively. The double-pass trapezoidal cross-section sealing grooves, with the inner silicone ring and the outer PTFE ring, form a dual sealing mechanism to ensure effective sealing. Once the two cabins are docked, cables and other equipment can be installed through the central opening of the ring interface 3.

[0043] In this embodiment, the dual-material sealing ring realizes segmented sealing in the pressure range of 0-30 MPa.

[0044] There are multiple internal support components 2 corresponding to the cabin bodies one by one. Each internal support component 2 includes multiple semicircular support frames. The multiple support frames are distributed inside the corresponding main cabin body 1 and fixed to the inner wall of the main cabin body 1.

[0045] As a specific implementation, the internal support component 2 adopts a bionic honeycomb (2a) lightweight bracket with a thickness of 80mm and a 30° arrangement. It is integrated with the inner wall of the cabin, and the load-bearing capacity is increased by 30% while reducing material consumption.

[0046] The connecting component 4 is an electromagnetic locking component, including a controller, a position sensor, a lock slot mechanism, a lock tongue mechanism and an electromagnetic coil 13. The lock slot mechanism includes a lock slot mounting shell 5 and a lock slot 6 configured on the lock slot mounting shell. The lock tongue mechanism includes a lock tongue mounting shell 9 and a lock tongue 10 configured on the lock tongue mounting shell 9. The lock tongue 10 is provided with an automatic reset spring. The electromagnetic coil 13 and the position sensor are electrically connected to the controller. The electromagnetic coil 13 surrounds the outer ring of the lock tongue 10. A through hole is formed on the lock slot mounting shell 5 and the lock tongue mounting shell 9. For the two main cabins 1 to be connected, the lock slot mechanism is configured in one of the main cabins. 1, and the through hole on the lock slot mounting shell 5 is communicated with the middle hole of the annular interface 3. The lock tongue mechanism is arranged on the annular interface 3 of the other main cabin body 1, and the through hole on the lock tongue mounting shell 9 is communicated with the middle hole of the annular interface 3. The controller energizes the electromagnetic coil 13 based on the connection instruction. After the electromagnetic coil 13 is energized, it drives the lock tongue 10 to embed into the lock slot 6 docked with it. The position sensor detects the distance between the lock tongue 10 and the lock slot 6 in real time and returns the detection information to the controller. Based on the detection information, after the lock tongue 10 is embedded in the predetermined position in the lock slot 6, it is determined that the two main cabin bodies 1 are locked and docked.

[0047] The through hole in the center of the lock slot mounting shell has an inner sealing ring 7 and an outer sealing ring for the through hole in the lock slot mounting shell. The through hole in the center of the lock tongue mounting shell has an inner sealing ring 11 and an outer sealing ring 12 for the through hole in the lock tongue mounting shell. The inner sealing ring is filled with silicone with a Shore hardness of 60±5 and a compression rate of 30% (in pre-compressed state), while the outer sealing ring is filled with polytetrafluoroethylene (PTFE) with 15% glass fiber reinforcement and a compressive strength of ≥25MPa. The double-channel trapezoidal cross-section sealing groove, with the inner sealing groove filled with silicone and the outer sealing groove filled with PTFE, forms a dual sealing mechanism to ensure effective sealing. After the two compartments are docked, cables and other installation operations can be performed through the central through hole.

[0048] In this embodiment, multiple lock slots 6 are arranged circumferentially on the lock slot mounting housing 5. Correspondingly, multiple lock tongues 10 are arranged circumferentially on the lock tongue mounting housing 9. Lock tongues 10 are made of martensitic stainless steel, have a wedge-shaped cross-section (8° inclination), a 20mm travel, and a return spring with a preload of 150N and a compression stroke of 15mm. In the event of a power outage, the spring forces the lock back to unlock, preventing the underwater equipment from becoming stuck. The wedge-shaped lock tongue 10 automatically adjusts to within ±3mm of alignment deviation to accommodate subsea installation errors.

[0049] The working process of connection component 4 is as follows: the underwater robot sends a connection command - the electromagnetic coil is energized - the lock tongue extends 15mm - is embedded in the docking lock groove - the position sensor confirms that it is in place - the sealing ring pressure is tested - the docking is completed.

[0050] An adsorption anchor is provided at the bottom of the main cabin 1, and the main cabin 1 is supported by a crane to sink to the target seabed position and is fixed by an attached anchor.

[0051] Based on the system disclosed in this embodiment, take a submarine data center deployed at a water depth of 30 meters as an example:

[0052] 1) Cabin manufacturing:

[0053] Material selection: TA18 titanium alloy, yield strength ≥800MPa, corrosion resistance grade C5-M.

[0054] Forming process: hot isostatic pressing technology is used for integral forming to eliminate weld weaknesses.

[0055] 2) Deployment process:

[0056] Step 1: Pre-install servers, cooling units, solid-state batteries, fiber optic slip rings, and sonar communication modules on land to different functional cabins (101, 102, 103), and fill the cabins with inert gas (nitrogen + sulfur hexafluoride mixture).

[0057] Step 2: The hull is lowered to the target location by a heavy-lift vessel, and the underwater robot activates the bottom adsorption anchor to fix it.

[0058] Step 3: The robotic arm connects the adjacent cabins according to the planned path, and the electromagnetic locking device automatically closes and detects the sealing.

[0059] 3) Operation and maintenance optimization: The faulty cabin can be recovered individually by releasing the electromagnetic lock without affecting the overall structure.

[0060] The structure of this embodiment is suitable for data storage and computing equipment deployment in high-pressure submarine environments, and can also be expanded to scenarios such as ocean observation and energy equipment.

[0061] The above is a detailed introduction to the hemispherical pressure-resistant cabin structure of a modular submarine data center provided by the present invention. Specific examples are used herein to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only used to help understand the method of the present invention and its core idea. At the same time, for those skilled in the art, according to the ideas of the present invention, there will be changes in the specific implementation methods and application scopes. In summary, the content of this specification should not be understood as a limitation on the present invention.
