Exemplary embodiments of the present disclosure are described below with reference to the accompanying drawings. It should be understood that the detailed description is intended only to teach one skilled in the art how to practice the disclosure, and is not intended to be exhaustive or to limit the scope of the disclosure.

The term "and/or" herein is merely an association describing an associated object, meaning that three relationships may exist, e.g., a and/or B, may mean: a exists alone, A and B exist simultaneously, and B exists alone. In addition, the term "at least one" herein means any one of a plurality or any combination of at least two of a plurality, for example, including at least one of A, B, C, and may mean including any one or more elements selected from the group consisting of A, B and C.

Taking a cabinet for a storage server as an example, referring to fig. 1 to 6, an underwater cabinet according to the present disclosure will be described. Referring to fig. 1, 3 and 4, a denotes an axial direction of the underwater cabinet and R denotes a radial direction of the underwater cabinet, unless otherwise specified.

After the servers are positioned in the cabinet, the underwater cabinet can be installed underwater by means of a lifting device such as a ship or shore. It should be understood that reference to "underwater" in this disclosure includes underwater in rivers, lakes, and seas.

In the present embodiment, the underwater cabinet includes a housing 10, a barrier 20, a frame 30, a floor mat 40, and legs 50.

Referring to fig. 1 and 2, the housing 10 is cylindrical, and optionally cylindrical. The housing 10 includes a cylindrical portion formed as a circumferential wall and two end caps 10b provided at both ends of the cylindrical portion. The cylindrical portion is formed by splicing a plurality of cylindrical sub-cylinders 10a in series in the axial direction a.

The inner cavity of the housing 10 is used for accommodating the server and equipment required for operation and maintenance of the server.

The housing 10 is secured underwater by feet 50 (e.g., to an underwater connection such as a shelf or other connecting support) at a depth generally below water that will allow the water to at least submerge the housing 10, and optionally the housing 10 is secured to the bottom of several to several hundred meters below water.

Referring to fig. 3 and 4, in the present embodiment, the inner cavity of the housing 10 is divided by the barrier 20 into two chambers, an apparatus chamber 10p and a buffer chamber 10q, respectively. The barrier 20 is provided with an inner door D2, and when the inner door D2 is opened, persons and equipment can be transferred between the equipment chamber 10p and the buffer chamber 10 q; with the inner door D2 closed, the apparatus chamber 10p and the buffer chamber 10q are sealed from each other, and in particular liquid cannot flow from the buffer chamber 10q to the apparatus chamber 10 p.

The equipment room 10p is a server area, and the rack 30 is disposed in the equipment room 10 p.

The buffer chamber 10q is a buffer area, and if personnel and/or equipment need to enter the server area to perform operation and maintenance on the server, the personnel and/or equipment can firstly pass through the buffer area.

An outer door D1 is provided on the end cap 10b adjacent to the buffer chamber 10q to allow personnel and/or equipment to enter the buffer chamber 10q from the outside of the housing 10 or to be transferred from within the buffer chamber 10q to the outside. With the outer door D1 open, personnel and equipment can be transferred between the outside and the buffer chamber 10 q; in the case where the outer door D1 is closed, the outside and the buffer chamber 10q are sealed from each other, and in particular, liquid cannot flow into the buffer chamber 10q from the outside.

The operation principle of the buffer is described next.

In the case where a person and/or equipment needs to enter the buffer chamber 10q from the outside, or in the case where a person and/or equipment needs to leave the buffer chamber 10q to the outside, the buffer chamber 10q is filled with water in advance so that the water pressure inside and outside the buffer chamber 10q is approximately equal, the outer door D1 can be opened more easily, and the person and/or equipment can be transferred between the outside and the buffer chamber 10q in a submerged manner more smoothly. It should be appreciated that when water is present in the buffer chamber 10q, the inner door D2 is in a closed state.

In case personnel and/or equipment need to enter the equipment chamber 10p from the buffer chamber 10q or need to enter the buffer chamber 10q from the equipment chamber 10p, the buffer chamber 10q is drained in advance. It should be understood that both the outer door D1 and the inner door D2 are in the closed state during the draining of the cushion chamber 10 q. In a state where the water in the buffer chamber 10q is at or near empty, the inner door D2 may be opened to allow personnel and/or equipment to be transferred between the equipment chamber 10p and the buffer chamber 10q to avoid water ingress in the equipment chamber 10p to damage the server or other devices.

Optionally, a water pump and an oxygen pump are disposed in the buffer chamber 10 q. The water pump is used to draw external water into the buffer chamber 10q and to discharge the water in the buffer chamber 10 q. An oxygen pump is used to fill the apparatus chamber 10p and the buffer chamber 10q with oxygen suitable for human breathing after a person enters the buffer chamber 10 q.

Optionally, a drying device is also provided in the buffer chamber 10q for drying the persons and/or equipment in the buffer chamber 10q that are ready to enter the equipment chamber 10p after the water in the buffer chamber 10q has been emptied.

The outer layer 11 and the inner layer 12 are made of a material such as a high strength, low density alloy or composite material as known in the art. The outer layer 11 and the inner layer 12 made of high-strength materials make the sub-cylinder 10a not easy to deform even under a large pressure under water. It will be appreciated that the cylindrical shape of the sub-cartridge 10a also contributes to increasing its structural strength.

The material for forming the soundproof layer 13 is, for example, a material known in the art which can reduce noise. The sound insulation layer 13 can reduce the influence of noise generated by the server on the external ecological environment.

Optionally, a liquid sensor (also called a liquid level sensor) is further arranged between the outer layer 11 and the inner layer 12. When a liquid leakage occurs due to, for example, damage to the housing 10, external water may enter between the outer layer 11 and the inner layer 12 and be sensed by the liquid sensor, and the liquid sensor can transmit a sensing signal to the control unit and provide an early warning.

Optionally, the outer surface of the outer layer 11 is provided with a plurality of outer heat dissipation fins (not shown), and the outer heat dissipation fins enable the housing 10 to have a larger contact area with external water, so as to accelerate heat dissipation.
