Abstract
Description
Technical Field
[0001] The present invention belongs to the technical field of marine engineering and data centers, and relates to a pressure-resistant emergency compartment redundancy system for a deep-sea suspended data center. Background Art
[0002] Deep-sea suspended data centers, a cutting-edge technology, currently face numerous challenges brought by the complex marine environment, particularly pressure resistance. Traditional pressure-resistant emergency chamber designs often utilize a single material and structure, making it difficult to balance the multiple requirements of high strength, lightweight, and flexibility. In practical applications, sudden pressure changes can damage the emergency chamber in the event of an emergency, such as an undersea earthquake or tsunami. This can disrupt the normal operation of the data center and even lead to serious consequences such as data loss.
[0003] While existing patents have explored pressure-resistant designs, they present significant limitations. Some focus on improving material strength while neglecting structural optimization, resulting in excessively heavy emergency chambers that hinder the flexible deployment of deep-sea suspended data centers. Other patents, while proposing multi-stage pressure relief, lack a corresponding intelligent linkage mechanism, resulting in an inaccurate and inefficient pressure relief process. Furthermore, they fail to adequately consider the rapid switching and pressure balancing of backup compartments, making it difficult to meet the extremely high reliability requirements of deep-sea environments. The construction of deep-sea suspended data centers is a key development in marine engineering, placing even higher demands on the performance of pressure-resistant emergency chambers. On the one hand, as data centers continue to expand in size and data storage and processing density increases, emergency chambers require greater pressure resistance and reliability. On the other hand, the complex and dynamic deep-sea environment requires emergency chambers to rapidly respond to pressure changes, enabling precise pressure relief and failover to ensure stable data center operation under extreme conditions. This places an urgent need for redundant design and intelligent control of pressure-resistant emergency chambers. Summary of the Invention
[0004] In view of this, an object of the present invention is to provide a pressure-resistant emergency compartment redundancy system for a deep-sea suspended data center.
[0005] In order to achieve the above object, the present invention provides the following technical solutions:
[0006] A pressure-resistant emergency compartment redundancy system for a deep-sea suspended data center comprises a pressure-resistant emergency compartment body, a multi-stage pressure relief valve, and a control system; the pressure-resistant emergency compartment body is composed of a plurality of hexagonal units spliced together; reinforcing ribs are provided between the hexagonal units and sealed by sealing rings; the pressure-resistant emergency compartment body comprises a main compartment section and a spare compartment section, which are arranged in parallel; the multi-stage pressure relief valve is provided at key compartment nodes, pressure concentration areas, and between the main compartment section and the spare compartment section; a pressure sensor is provided in the multi-stage pressure relief valve; the control system is used to open the multi-stage pressure relief valve step by step to relieve pressure based on pressure data collected by the pressure sensor, and to close the multi-stage pressure relief valve after the pressure is restored.
[0007] Furthermore, the multi-stage pressure relief valve includes three levels of pressure relief thresholds; the first level pressure relief threshold is used to deal with slight overpressure; the second level pressure relief threshold corresponds to sudden pressure fluctuations; and the third level pressure relief threshold covers extreme working conditions.
[0008] Furthermore, the multi-stage pressure relief valve is arranged between the main compartment and the spare compartment and is connected to the outside through a pipeline, thereby realizing the parallel arrangement of the main compartment and the spare compartment.
[0009] Furthermore, when a failure occurs in the main compartment, the control system closes the multi-stage pressure relief valves between the main compartment and the pipeline, and simultaneously opens the multi-stage pressure relief valves between the spare compartment and the pipeline, allowing the spare compartment to take over the work.
[0010] Furthermore, during the switching process between the main compartment and the spare compartment, the control system controls the multi-stage pressure relief valve to respond step by step according to the pressure change.
[0011] Furthermore, both ends of the pressure-resistant emergency cabin body are provided with heads.
[0012] Furthermore, the hexagonal unit has a wall thickness of 3-5 mm and is made of titanium alloy or carbon fiber composite material.
[0013] The beneficial effects of the present invention are:
[0014] 1. The present invention adopts a pressure-resistant emergency cabin with a honeycomb topology structure. Through its high specific strength and specific stiffness, it can effectively disperse pressure, reduce the weight of the cabin, and significantly improve the pressure resistance performance, making the cabin more stable and reliable in deep-sea high-pressure environments.
[0015] 2. By providing a backup compartment, this invention can quickly take over when the primary compartment fails, ensuring continuous system operation. This redundant design significantly improves system reliability and safety, reducing the risk of system failure due to single-point failures.
[0016] 3. The graded pressure relief mechanism of the multi-stage pressure relief valve of the present invention can accurately control the pressure relief amount according to different pressure conditions.
[0017] 4. The modular design of the honeycomb unit makes processing, assembly, and maintenance simpler and faster. Furthermore, by varying the number and position of the winged side panels, a variety of vertex-based multi-level honeycomb topologies can be flexibly configured to meet the performance requirements of different scenarios, further enhancing the system's adaptability and flexibility.

[0027] Example 1:
[0028] like Figure 1-2 As shown, the present invention provides a redundant system for the pressure-resistant emergency compartment of a deep-sea suspended data center, including a cylindrical main compartment 1, a honeycomb topology structure, reinforcing ribs 6 and sealing rings 7, a multi-stage pressure relief valve 3 system, a pressure sensor 4, a spare compartment 2, an intelligent linkage mechanism, etc. The various parts work together to achieve fast and precise buoyancy adjustment, effectively cope with the complex and changeable deep-sea environment, and ensure the stability and safety of the data center.
[0029] Specifically, the main compartment 1 is a cylindrical hull constructed from titanium alloy or carbon fiber composite material. Its interior features a hexagonal honeycomb topology with a wall thickness of 3-5mm for high strength and lightweight design. End caps are installed at each end to ensure containment, while internal sealing is achieved through reinforcing ribs 6 and O-rings 7, enhancing structural stability and ensuring tightness between cells. A multi-stage pressure relief valve system 3 is installed at key nodes and pressure-concentrated areas within the compartment. Equipped with built-in pressure sensors, it responds to pressure fluctuations in a step-by-step manner. Furthermore, a backup compartment 2, arranged in parallel with the main compartment 1 and sharing the same functions and dimensions, is equipped with pressure sensors 4. This allows for automatic switching and pressure balancing in the event of a failure in the main compartment 1. The entire system is controlled through an intelligent linkage mechanism, ensuring precise and efficient pressure relief during pressure fluctuations and rapid failover to the backup compartment in the event of a main compartment failure. This significantly enhances the reliability and safety of the deep-sea suspended data center in complex marine environments, ensuring stable operation under extreme conditions.
[0030] In the present invention, a plurality of hexagonal units are evenly distributed inside the cabin, and these units represent a honeycomb structure. In order to enhance the stability of the structure, reinforcing ribs 6 are provided between each hexagonal unit. O-rings are provided at the edges of the hexagonal units to ensure the sealing between the units. A plurality of parallel multi-stage pressure relief valves with built-in pressure sensors 4 are provided at the key nodes or pressure concentration areas of the cabin. The multi-stage pressure relief valve is connected to the outside of the cabin through a pipe as a pressure relief path. Pipes and multi-stage pressure relief valves are provided between the main cabin section and the spare cabin section, thereby arranging them in parallel, and a connection and switching control system with the main cabin section is provided next to the cabin.
[0031] The control system responds to pressure levels by releasing pressure in stages and closing after pressure is restored. Because deep-sea pressure increases linearly with depth (approximately 0.1 MPa per 10 meters), assuming a data center is deployed at a depth of 800-1000 meters, with a typical operating pressure of approximately 8-10 MPa, a three-stage pressure relief valve is implemented. The first-stage pressure relief threshold (8 MPa) is slightly higher than normal pressure to address minor overpressures; the second-stage (12 MPa) responds to sudden pressure fluctuations (such as undersea earthquakes or ocean current shocks); and the third-stage (15 MPa) covers extreme operating conditions (such as equipment failures or rare natural disasters), ensuring system safety under extreme pressures. Therefore, when pressure rises slightly above 8 MPa, the first-stage pressure relief channel of the multi-stage pressure relief valve opens. If the pressure continues to rise to 12 MPa, the second-stage pressure relief channel opens. When the pressure reaches 15 MPa, all pressure relief channels open, achieving rapid pressure relief. When the system pressure drops to a safe range, each pressure relief channel closes in sequence, restoring normal system operation.
[0032] Through the above solution, combined with the synergistic effect of the cellular topology and the multi-stage pressure relief valve, the deep-sea suspended data center can achieve reliable pressure resistance and emergency protection in complex marine environments, ensuring the stable operation of the data center.
[0033] Example 2:
[0034] like Figure 3 As shown, the pressure-resistant emergency compartment redundancy system of the deep-sea suspended data center of the present invention is designed by the following method:
[0035] Step 1: Divide the interior of the main emergency cabin 1 into multiple hexagonal units, set the honeycomb wall thickness to 3-5 mm, and use titanium alloy or carbon fiber composite materials to make the honeycomb units.
[0036] Step 2: Reinforcement ribs 6 are provided between the honeycomb units, which are sealed with O-rings, and the honeycomb units are designed into a modular structure.
[0037] Step 3: The multi-stage pressure relief valve 3 is installed between the main compartment 1 and the spare compartment 2, and is arranged in parallel with the multi-stage pressure relief valve 3 through the pipeline 5.
[0038] Step 4: Pressure sensors 4 are installed inside the multi-stage pressure relief valve 3 and on top of the main compartment 1 to monitor pressure changes within the system in real time. When the pressure exceeds 8 MPa, the first-stage pressure relief channel opens to partially release pressure. If the pressure rises to 12 MPa, the second-stage pressure relief channel opens to increase the pressure relief. At 15 MPa, all channels are fully opened for rapid pressure relief. Once the system pressure drops to a safe range, each channel is closed in sequence to resume operation.
[0039] Step 5: The main compartment 1 and the spare compartment 2 are arranged in parallel, with the same functions and dimensions.
[0040] Step 6: During normal operation, main compartment 1 operates while backup compartment 2 stands by. If a fault occurs in main compartment 1, the system automatically closes multi-stage pressure relief valve 3 connecting main compartment 1 to the external pipeline and simultaneously opens multi-stage pressure relief valve 3 connecting backup compartment 2 to the external pipeline, allowing backup compartment 2 to quickly take over. During this switchover, multi-stage pressure relief valve 3 responds step by step based on pressure changes.
[0041] Step 7: Install pressure sensors 4 at key locations of the main compartment 1 and the backup compartment 2 to monitor pressure changes in real time and transmit data to the control system.
[0042] Step 8: When the pressure exceeds the set threshold, the multi-stage pressure relief valve 3 is triggered. After the standby compartment 2 takes over, the system continues to monitor its operating status in real time to ensure safe operation.
[0043] Step nine: modularly assemble the honeycomb unit and the multi-stage pressure relief valve 3 and other components to complete the construction of the entire pressure emergency compartment section, and perform pressure testing and functional testing on the assembled pressure emergency compartment section.
[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not limiting. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solutions, which should all be included in the scope of the claims of the present invention.
