Description

Technical Field

[0001] The present invention relates to the field of underwater data center construction, and in particular to a corridor-cabin connection and design method of a corridor-type submarine data center. Background Art

[0002] At present, the construction of submarine data centers usually adopts an integrated module construction method, that is, all equipment, facilities and systems are pre-integrated into a complete modular unit, assembled and tested on land, and then the entire module is directly sunk to the seabed for installation.

[0003] Although this method simplifies the construction process, it also brings some problems. On the one hand, since the data cabin is completely closed, daily maintenance and repairs become extremely difficult. Usually, staff cannot directly enter the data cabin for maintenance work. On the other hand, since the data cabin is sunk in the deep sea, professional divers are usually required to perform underwater operations, which greatly increases the cost and complexity of maintenance. At the same time, the practice of directly dropping it onto the seabed after integrated construction limits its scale of application. The high maintenance cost and difficulty of operation make this practice difficult to promote on a large scale.

[0004] Therefore, a corridor-cabin construction method for submarine data centers is proposed. Due to the importance of servers in the submarine data cabin and their inaccessibility to water, a specific connection method needs to be designed to meet the airtightness requirements of the submarine data cabin, while also ensuring disassembly and maintainability. Summary of the invention

[0005] The purpose of the present invention is to solve the problem that there is currently no reliable connection design for the new corridor-cabin construction method of the submarine data center. A corridor-cabin connection and design method for a pipeline corridor-type submarine data center is proposed, which ensures the airtightness, disassembly and maintainability of the submarine data cabin, and can be widely used in the field of underwater data center construction.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] A corridor-cabin connection method for a pipe gallery-type submarine data center includes an underwater suspended pipe gallery and a submarine data cabin, characterized in that the underwater suspended pipe gallery is provided with a closed door on the side, and a connecting channel is extended at the closed door, the connecting channel and the underwater suspended pipe gallery are a whole, and a drainage channel and an air pressure balance channel are provided to connect with the underwater suspended pipe gallery, the connecting channel is connected to the submarine data cabin through a rubber waterstop, the submarine data cabin is provided with a cabin door at the connection, the edge of the cabin door is provided with a sealing ring, a cabin door handle and a rotary locking mechanism; the cabin door is also provided with a pressure balance valve; a humidity sensor is provided in the connecting channel.

[0008] As a preferred technical solution of the present invention, the enclosed door adopts a pressure-resistant watertight door, and the pressure-resistant watertight door satisfies the requirement of preventing water from seeping into the interior of the underwater suspended pipe gallery in a seawater environment within a depth of 50m.

[0009] As a preferred technical solution of the present invention, the rubber waterstop is a GINA waterstop, which is connected to the submarine data cabin by hydraulic crimping. The GINA waterstop uses an OMEGA waterstop on the inner side of the connecting channel as a second waterproof measure.

[0010] As a preferred technical solution of the present invention, the hatch is a double-layer door panel structure, which is divided into an inner and outer layer. The outer door panel is on the outside of the submarine data cabin, and the inner door panel is on the inside of the submarine data cabin. The inner and outer door panels are both provided with a main sealing ring and an auxiliary sealing ring. The auxiliary sealing ring is arranged on the inner side of the main sealing ring. The hatch door activates the rotary locking mechanism by rotating the hatch door handle to press the hatch door tightly against the door frame, thereby squeezing and deforming the main sealing ring and the auxiliary sealing ring.

[0011] As a preferred technical solution of the present invention, when the pressure difference between the inside and outside of the cabin door exceeds a threshold value ΔP, the pressure balancing valve will sound an alarm when the cabin door handle is rotated, and the threshold value ΔP is 0.05MPa.

[0012] As a preferred technical solution of the present invention, when the relative humidity of the connecting passage exceeds a threshold value M1, the humidity sensor will sound an alarm when the door handle is rotated, and the threshold value M1 is 60%.

[0013] A corridor-cabin connection design method for a pipe gallery-type submarine data center includes a non-seismic design, a seismic design, and a maintenance and repair design under seawater pressure. The method is characterized in that the maintenance and repair design includes, in addition to normal internal maintenance and repair, external structural maintenance and repair after the submarine data cabin is salvaged, and specifically includes the following steps:

[0016] S2, salvage the seabed data cabin;

[0022] As a preferred technical solution of the present invention, in step S1, the inner connection and the outer connection are connected by detachable bolts, the bolts, nuts and gaskets of the outer connection are made of materials with high corrosion resistance and the cathodic protection method of sacrificial anode is used to protect the outer connection from corrosion.

[0023] As a preferred technical solution of the present invention, in step S4, the threshold M2 is 40%.

[0042] S4. Return to the data center for installation;

[0043] The repaired or newly transferred submarine data cabin is transported back to the submarine data center and positioned at the original position of the submarine data cabin. The connecting channel is reconnected with the submarine data cabin through the rubber water stop. After the outer connection is reinstalled, the drainage channel and the air pressure balance channel are opened to drain the seawater in the connecting channel.
