And after maintenance personnel finish maintenance, the first sealing door 24 is opened to enter the landing cabin, the first sealing door 24 is closed, then the second sealing door 25 is opened, the landing cabin 22 is separated, and the landing cabin returns to the ground through diving equipment.

Thus, compared with the prior art that the underwater data center is maintained by constructing the water platform and the fixed maintenance channel, the underwater data center is not required to be constructed and maintained, the construction cost is greatly reduced, and the development of the underwater data center is facilitated.

In some embodiments, as shown in fig. 2, the data pod 21 includes: a connection pod 211 and an IDC pod 212. The IDC pod 212 has electronic devices such as a computer server, a router, and a switch.

The connection pod 211 is located between the landing pod 22 and the IDC pod 212, and a first sealing door 24 is provided between the connection pod 211 and the landing pod 22; a third sealing door 26 is arranged between the connection pod 211 and the IDC pod 212, the third sealing door 26 being used to divide the IDC pod 212 and the connection pod 211 into two separate pods.

That is, the connection pod 211 is disposed between the landing pod 22 and the IDC pod 212, the connection pod 211 acting as a staging pod and maintenance personnel can enter the IDC pod 212 through the connection pod 211.

Thus, after a maintenance person opens the first sealing door 24 into the connection pod 211, the first sealing door 24 may be closed and then the third sealing door 26 opened into the IDC pod 212. That is, the connection pod 211 serves as a transit pod when maintenance personnel enter the IDC pod 212, and it is possible to prevent external water from being poured into the landing pod 22 due to an unexpected situation to flow into the IDC pod 212 to damage the electronics within the IDC pod 212 when the second sealing door 25 is opened. In this way, maintenance personnel can transfer through the connection pod 211, improving the water resistance of the IDC pod 212, and further improving the safety of the IDC pod 212.

In some embodiments, the capsule-based underwater IDC proximal maintenance system 100 further comprises: the first air conveying pipeline and the first air pump. Wherein the first gas transmission pipeline is used for communicating the underwater cabin 20 with the water cabin 10; the first air pump is provided on the first air delivery line for charging the underwater compartment 20 with oxygen.

The air pump is a device for exhausting air from an enclosed space or adding air from the enclosed space. The air pump is mainly divided into an electric air pump, a manual air pump, a foot-operated air pump and an electric air pump. The electric air pump is an air pump taking electric power as power, and air pressure is generated by continuously compressing air through electric power.

In one possible implementation, one end of the first gas transmission line communicates with the underwater compartment 20, and the other end of the first gas transmission line communicates directly with the outside air through the water upper compartment 10.

Thus, after the first air pump is started, the first air pump can convey external air into the underwater cabin 20 through the first air conveying pipeline, so that an aerobic environment is provided for maintenance personnel, and maintenance personnel can conveniently overhaul and maintain the IDC cabin 212.

In another possible implementation, one end of the first gas line communicates with the underwater compartment 20, and the other end of the first gas line communicates with an oxygen plant disposed within the water compartment 10, which is capable of producing high concentrations of oxygen. Thus, after the first air pump is started, the first air pump can convey the high-concentration oxygen produced by the oxygen production equipment into the underwater cabin 20 through the first air conveying pipeline, so that an aerobic environment is provided for maintenance personnel rapidly, and maintenance personnel can overhaul and maintain the data cabin 21 in time conveniently.

Thus, after the maintenance personnel enter the underwater cabin 20, oxygen can be input into the underwater cabin 20, and the maintenance personnel can take off the oxygen bottle, so that the maintenance personnel can conveniently overhaul and maintain.

Optionally, as shown in fig. 4, the nacelle-based underwater IDC proximal maintenance system 100 further includes: a first oxygen content detector 60 and a second oxygen content detector 70; a first oxygen content detector 60 is disposed in the landing bay 22 for detecting the oxygen content in the landing bay 22; a second oxygen content detector is provided in the data compartment 21 for detecting the oxygen content in the data compartment 21.

It will be appreciated that the data pod 21 includes: in the case of the connection pod 211 and IDC pod 212, the second oxygen content detector 70 may be provided in two, with two second oxygen content detectors 70 being provided in the connection pod 211 and IDC pod 212, respectively.

The first oxygen content detector 60 and the second oxygen content detector 70 may be oxygen content detectors, and the first oxygen content detector 60 and the second oxygen content detector 70 may also be oxygen concentration detectors, which are not limited herein.

Thus, when maintenance personnel enter the landing bay 22, the oxygen content of the IDC bay 212 and the connection bay 211 can be checked, and after the oxygen concentration of the landing bay 22 and the data bay 21 reaches a proper concentration, the oxygen cylinder is taken down, and the maintenance personnel enter the IDC bays 212 through the connection bay 211 to maintain and overhaul the electronic equipment in the IDC bays 212.

In some embodiments, the capsule-based subsea IDC proximal maintenance system 100 further comprises: and a second air pump provided on the first air delivery line for exhausting the air in the underwater compartment 20.

The second air pump may refer to the first air pump, which is not limited in this application.

In addition, it is understood that the second air pump may refer to the same air pump as the first air pump, which is capable of blowing and sucking air, thereby enabling the air to be introduced into the underwater compartment 20 or the air to be discharged out of the underwater compartment 20.

In addition, if an air pump capable of exhausting air from the underwater compartment 20 is provided, one end of the first air-sending line may communicate with the underwater compartment 20, and the other end of the first air-sending line may communicate with the outside air directly through the water compartment 10.

Thus, after the maintenance personnel leave the underwater cabin 20, the gas in the underwater cabin 20 can be discharged through the second air pump, so that the underwater cabin 20 is in an anaerobic environment, and the risks of oxidization of equipment and circuit fire are reduced.

In some embodiments, the capsule-based underwater IDC proximal maintenance system 100 further comprises: a second air delivery line and a third air pump, wherein the second air delivery line communicates the IDC compartment 212 chamber with the water compartment 10; a third air pump is provided on the second air delivery line for filling the underwater compartment 20 with inert gas.

The third air pump may refer to the description of the first air pump, and the second air delivery pipeline may refer to the description of the first air delivery pipeline, which is not repeated herein.

The inert gas may be helium, neon, or the like, and is not limited thereto in this application.

In one possible implementation, one end of the second gas line may be in communication with IDC compartment 212 and the other end of the first gas line may be in communication with inert gas equipment of the water compartment 10.

In another possible implementation, one end of the second gas line may be in communication with IDC compartment 212 and the other end of the first gas line may be in communication with a closed container filled with an inert gas within the water compartment 10.

Thus, when activated, the third air pump is capable of delivering inert gas into the IDC compartment 212 through the second gas delivery line.

In this way, after the maintenance personnel leave the underwater cabin 20, inert gas can be input into the IDC data cabin 21 through the second gas transmission pipeline, so as to prevent the electronic equipment in the data cabin 21 from firing and ensure that the underwater data center can stably operate.

In some embodiments, as shown in fig. 5, the capsule-based underwater IDC proximal maintenance system 100 further comprises: a water intake assembly 80, the water intake assembly 80 being disposed on the landing bay 22, the water intake assembly 80 for flowing external water into the landing bay 22.

Thus, before maintenance personnel need to enter the landing bay 22 in the water, the water inlet assembly 80 can be started to allow external water to enter the landing bay 22, so that the landing bay 22 is balanced with external water pressure, and the maintenance personnel can conveniently enter the landing bay 22. Alternatively, when maintenance personnel need to enter the water from the underwater compartment, the water intake assembly 80 may be activated to allow external water to enter the landing bay 22, equalizing the landing bay 22 with external water pressure, and facilitating maintenance personnel to leave the landing bay 22.

The landing bay 22 may be filled with gas, water, or both in a normal operation of the underwater IDC proximal maintenance system 100 based on a capsule, which is not limited in this application.

In one possible implementation, the water intake assembly 80 includes: the landing cabin 22 is also provided with a water inlet communicated with the outside, and the water inlet valve is arranged at the water inlet. Thus, by controlling the opening and closing of the water inlet valve, external water flows into the landing cabin 22 under the action of water pressure, so that the landing cabin is balanced with the external water pressure, and maintenance personnel can conveniently enter the landing cabin 22.

In another possible implementation, the water intake assembly may further include: the filter screen is arranged at the water inlet and is positioned at one side of the water inlet valve away from the landing cabin 22.

Thus, when external water enters the landing bay 22, impurities in the water can be filtered, so that the impurities are prevented from entering the landing bay 22 and polluting the landing bay 22.

In some embodiments, the capsule-based underwater IDC proximal maintenance system 100 further comprises: a weight 90, the weight 90 being connected to the underwater compartment 20 for suspending the underwater compartment 20 in water.

In this way, the underwater chamber 20 can be suspended in water, and the underwater chamber 20 is prevented from rising out of the water, resulting in an increase in the temperature of the underwater chamber 20.

According to the above-described capsule-based near-end maintenance system 100 for underwater IDC, when maintenance and repair of the underwater IDC capsule 212 are required, a maintenance person can put spare parts to be replaced in the waterproof spare parts bag 91, and then the maintenance person wears the wetsuit and carries the spare parts bag 91, submerging the water area in which the underwater capsule 20 is located. The water inlet assembly 80 is started, the second sealing door 25 is opened after the landing cabin 22 is filled with water, the water enters the landing cabin 22 after the water pressure inside and outside the landing cabin 22 is balanced, and the second sealing door 25 is closed. The maintenance personnel turn on the drain assembly 23 and activate the first air pump to charge the landing bay 22 with high pressure air until the water inside the landing bay 22 is empty, closing the drain assembly 23. After the maintenance personnel observe the first oxygen content detector 60 of the landing bay 22 and determine that the oxygen content is up to standard (i.e., meets the concentration required for human breathing), the wetsuit is removed. Thereafter, the maintenance personnel perform the air exchange work of the connection pod 211 and IDC pod 212 and determine that the oxygen content of the connection pod 211 and IDC pod 212 is up to standard. The maintenance personnel open the first sealing door 24, carry the spare part bag 91 into the connection pod 211, and close the first sealing door 24. After the maintenance personnel complete their own cleaning and the spare part bag 91 inside the connection pod 211, wear the protective suit, carry the spare part bag 91, open the third sealing door 26, enter the IDC pod 212, and close the third sealing door 26. The maintenance personnel complete replacement of spare parts, load the waste parts into the spare parts bag 91, open the third sealing door 26 after confirming that the oxygen content of the connecting cabin 211 and the logging cabin 22 reach the standard, carry the spare parts bag 91, enter the connecting cabin 211, and close the third sealing door 26. The maintenance personnel take off the protective suit, load the protective suit into the spare part bag 91, open the first sealing door 24, carry the spare part bag 91, enter the landing bay 22, and close the first sealing door 24. The maintenance personnel wear the wetsuit and perform the ventilation work of the connection pod 211 and the IDC pod 212, i.e. evacuate the original air and fill in inert gas (which can effectively prevent IDC fires). Thereafter, the service person activates the water intake assembly 80 and activates the second pump to pump air out of the landing bay 22 until the landing bay 22 is full of water. Finally, the maintenance personnel opens the second sealing door 25, carries the spare part bag 91, walks out of the landing bay 22, closes the second sealing door 25, and completes the maintenance task of the underwater IDC bay 21.

The foregoing is merely a specific embodiment of the present application, but the protection scope of the present application is not limited thereto, and any changes or substitutions within the technical scope of the present disclosure should be covered in the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
