Description

Technical Field

[0001] The present invention relates to the technical field of underwater data centers, and in particular to a large-scale underwater data center and a method for arranging a large-scale underwater data center. Background Art

[0002] At present, underwater data centers use a solution in which the shore station is connected to an underwater substation via an optoelectronic composite cable, and the underwater substation is connected to as many data cabins as possible.

[0003] In the actual process of large-scale deployment of data cabins, the number of cable ends that can be distributed in the substation is limited, and there are spacing requirements for the deployment of data cabins (underwater installation and deployment generally require a safety spacing of about 20m). If the substation is to connect as many data cabins as possible, the distance between the data cabin and the substation needs to be increased, and then the seabed area will be greatly increased. Even if the site area is increased, there are too many cables from the substation, and the submarine cables near the substation are prone to cross-knotting, which increases the difficulty of subsequent maintenance and deployment. Summary of the invention

[0004] In view of this, the present invention provides a large-scale underwater data center to solve the problem that when the underwater data center adopts a solution in which a shore station is connected to an underwater substation through an optoelectronic composite cable, and the underwater substation is connected to as many data cabins as possible, when it is necessary to connect as many data cabins as possible, the seabed area will be greatly increased and the submarine cables near the substation are prone to cross-knotting.

[0005] In a first aspect, the present invention provides a large-scale underwater data center, comprising:

[0006] At least one power distribution assembly, the power distribution assembly comprising a plurality of substations arranged in series;

[0007] The substation at the starting end of any of the power distribution components is connected to a main submarine cable, and the other end of the main submarine cable is suitable for connection to a shore station;

[0008] Any of the substations is connected to a number of data cabins.

[0009] The above structure connects several substations in series to form a power distribution assembly. When connecting the shore station, it is only necessary to connect the substation at the starting end to the shore station through the main submarine cable. When setting up the data cabin, several data cabins are connected to any of the substations. Since the data cabins have spacing requirements, the underwater installation and deployment generally require a safe spacing of about 20m. Therefore, by connecting several substations in series, and then connecting several data cabins to each substation, this method is different from the traditional method of connecting the shore station to an underwater substation through an optoelectronic composite cable, and the underwater substation is connected to as many data cabins as possible, that is, the data cabins are arranged in a ring around the underwater substation. The present invention can greatly reduce the distance between the data cabin and the substation, shorten the length of the submarine cable, and reduce the risk of cross-knotting of the submarine cable; the number of data cabins that can be deployed per unit seabed area is greatly increased, and the longitudinal direction of the sea area is also fully utilized.

[0010] In an optional embodiment, there are at least two power distribution components, and the power distribution components are placed in parallel.

[0011] During use, the above structure increases the number of power distribution components and thus the number of data cabins, changing the original circular layout with the substation as the center to cable layout on both sides of the substation. The entire station looks neat and orderly, greatly improving the utilization rate of the sea area.

[0012] In an optional embodiment, the data compartments connected to any one of the power distribution components are distributed in two rows on both sides of the power distribution components in this row.

[0013] In an optional implementation, the number of the data cabins disposed on both sides of the substation is the same.

[0014] In an optional implementation, any of the data cabins is individually connected to a sub-sea cable, and the other end of the sub-sea cable is connected to the substation.

[0015] In an optional implementation, the data cabin and the substation are both provided with submarine cable ends, and the sub-submarine cables are respectively connected to the submarine cable ends on the data cabin and the substation.

[0016] The above structure, by arranging the submarine cable ends on the data cabin and the substation, can conveniently connect the data cabin with the substation through the sub-submarine cable. When installing the data cabin underwater, the data cabins are laid out one by one in sequence. Before laying each data cabin, the corresponding sub-submarine cable is first picked up from the water, the waterproof protection joint of the submarine cable is removed, and the submarine cable joint is connected to the data cabin on the installation ship and powered on for testing. The installation is convenient and efficient.

[0017] In an optional implementation, a submarine cable connector is preset on any of the substations, and two adjacent substations are electrically connected by the submarine cable connector.

[0018] In the above structure, a submarine cable connector is preset on the substation. When installing the substation at the starting end of the power distribution assembly, that is, the first-level substation, the submarine cable connector on the first-level substation is connected to the main submarine cable. After the first-level substation is placed, the submarine cable connector of the first-level substation for connecting to the next-level substation is placed at a preset position, and the position coordinates are marked and recorded. When the next-level substation is connected, the next-level substation is connected to the submarine cable connector.

[0019] In an optional embodiment, the large-scale underwater data center also includes a plurality of data cabin basic bases, which are arranged on opposite sides of the substation, and a plurality of the data cabins connected to one side of the substation are placed on the data cabin basic base on the side of the substation.

[0020] In the above structure, several data cabins connected to one side of the substation share a data cabin basic base, which can provide protection for the data cabin while fixing it to prevent the data cabin from colliding with other structures placed on the seabed. In this way, there is no need to consider the safety distance requirements for the placement of different structures, and the space utilization rate is higher.

[0021] In an optional embodiment, the data cabin base is frame-shaped.

[0022] In a second aspect, the present invention provides a method for arranging a large-scale underwater data center, using a large-scale underwater data center, comprising the following steps:

[0023] Step 1: Before laying the first-level substation, connect the submarine cable connector on the first-level substation to the pre-laid main submarine cable, and remotely start the substation to test whether the main submarine cable is well connected;

[0024] Step 2: After the first-level substation is laid out, the submarine cable connector of the first-level substation used to connect to the next-level substation is placed at the preset position, and the position coordinates are recorded. When the next-level substation is connected, it will be connected to the submarine cable connector.

[0025] Step 3: Lay out the data cabin base according to the predetermined position, and coil all the submarine cables on this side from the cable coiling rack in turn, and remove the cable coiling rack;

[0026] Step 4: Lay out the data cabins one by one in order. Before laying out each data cabin, first pick up the corresponding submarine cable from the water, remove the submarine cable waterproof protection joint, connect the submarine cable joint and the data cabin on the installation ship, power on and test them, and then lay them to the underwater data cabin foundation base;

[0027] Step 5: When laying the data cabin on the other side, first lay the data cabin foundation base, and then coil all the submarine cables on this side from the cable reel rack in sequence, remove the cable reel rack, and lay the data cabins one by one in sequence;

[0028] Step 6: Repeat the above steps when deploying the next-level substation and data cabin modules.

[0029] This large-scale underwater data center layout method divides the substations into different levels. The first-level substation can be connected to the second-level substation, which retains very good scalability. Each first-level substation can be connected to the second-level substation. The size of a single substation can be made small, and there is no need to reserve too many interfaces or make too much initial one-time investment. It has good scalability. The substation connected by each main submarine cable and all the data cabin modules connected to the next-level substation are called a station. The distance between stations is greatly reduced, and the original circular layout with the substation as the center is changed to cable layout on both sides of the substation. The entire station looks neat and orderly, greatly improving the utilization rate of the sea area.

[0030] The large-scale underwater data center and the large-scale underwater data center layout method provided by the present invention have the following advantages:

[0031] 1. The present invention provides a large-scale underwater data center, comprising at least one power distribution component, wherein the power distribution component comprises a plurality of substations arranged in series, wherein the substation at the starting end of any of the power distribution components is connected to a main submarine cable, and the other end of the main submarine cable is suitable for connection to a shore station; and any of the substations is connected to a plurality of data cabins.

[0032] The large-scale underwater data center of this structure is formed by connecting several substations in series to form a power distribution component. When connecting to the shore station, it is only necessary to connect the substation at the starting end to the shore station through the main submarine cable. When setting up the data cabin, several data cabins are connected to any of the substations. Since the data cabins have spacing requirements, the underwater installation and deployment generally require a safe spacing of about 20m. Therefore, by connecting several substations in series, and then connecting several data cabins to each substation, this method is different from the traditional method of connecting a shore station to an underwater substation through an optoelectronic composite cable, and the underwater substation is connected to as many data cabins as possible, that is, the data cabins are arranged in a ring around the underwater substation. The present invention can greatly reduce the distance between the data cabin and the substation, shorten the length of the submarine cable, and reduce the risk of cross-knotting of the submarine cable; the number of data cabins that can be deployed per unit seabed area is greatly increased, and the longitudinal direction of the sea area is also fully utilized.

[0033] 2. The present invention provides a large-scale underwater data center, wherein the number of the power distribution components is at least two and the power distribution components are placed in parallel.

[0034] During use, the large-scale underwater data center with this structure increases the number of power distribution components and thus the number of data cabins, changing the original circular layout with the substation as the center to cable layout on both sides of the substation. The entire site looks neat and orderly, greatly improving the utilization rate of the sea area.

[0036] The large-scale underwater data center of this structure is equipped with submarine cable ends on both the data cabin and the substation, so that the data cabin can be conveniently connected to the substation through the sub-submarine cable. When installing the data cabin underwater, the data cabins are laid out one by one in sequence.

The installation is convenient and efficient.

[0037] 4. In a large-scale underwater data center provided by the present invention, a submarine cable connector is preset on any of the substations, and two adjacent substations are electrically connected by the submarine cable connector.

[0038] The large-scale underwater data center of this structure has a submarine cable connector preset on the substation. When installing the substation at the starting end of the power distribution assembly, that is, the first-level substation, the submarine cable connector on the first-level substation is connected to the main submarine cable. After the first-level substation is placed, the submarine cable connector of the first-level substation for connecting to the next-level substation is placed at a preset position, and the position coordinates are marked and recorded. When the next-level substation is connected, the next-level substation is connected to the submarine cable connector.

[0040] In a large-scale underwater data center of this structure, several data cabins connected to one side of the substation share a data cabin basic base, which can provide protection for the data cabin while fixing it to prevent the data cabin from colliding with other structures placed on the seabed. In this way, there is no need to consider the safety distance requirements for the placement of different structures, and the space utilization rate is higher.

[0041] 6. The present invention provides a large-scale underwater data center, which grades substations. The first-level substation can be connected to the second-level substation, retaining very good scalability. Each first-level substation can be connected to the second-level substation, and the size of a single substation can be made small.

In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0063] Example 1

[0064] At present, underwater data centers use a solution in which the shore station is connected to an underwater substation via an optoelectronic composite cable, and the underwater substation is connected to as many data cabins as possible.

[0065] In the actual process of large-scale deployment of data cabins, the number of cable ends that can be distributed in the substation is limited, and there are spacing requirements for the deployment of data cabins (underwater installation and deployment generally require a safety spacing of about 20m). If the substation is to connect as many data cabins as possible, the distance between the data cabin and the substation needs to be increased, and then the seabed area will be greatly increased. Even if the site area is increased, there are too many cables from the substation, and the submarine cables near the substation are prone to cross-knotting, which increases the difficulty of subsequent maintenance and deployment.

[0066] To this end, this embodiment provides a large-scale underwater data center to solve the problem that when the underwater data center uses a shore station to connect to an underwater substation through an optoelectronic composite cable, and the underwater substation connects as many data cabins as possible, when it is necessary to connect as many data cabins as possible, the seabed area will be greatly increased and the submarine cables near the substation are prone to cross-knotting.

[0067] In this embodiment, the large-scale underwater data center includes at least one power distribution component, which includes several substations 1 arranged in series. The substation 1 at the starting end of any power distribution component is connected to a main submarine cable 2, and the other end of the main submarine cable 2 is suitable for connection to a shore station; any substation 1 is connected to several data cabins 3.

[0068] In this embodiment, several substations 1 are connected in series to form a power distribution component. When connecting the shore station, only the substation 1 at the starting end needs to be connected to the shore station through the main submarine cable 2. When setting the data cabin 3, several data cabins 3 are connected to any substation 1. Since the data cabin 3 has a spacing requirement, the underwater installation and deployment generally requires a safety spacing of about 20m. Therefore, several substations 1 are connected in series, and then several data cabins 3 are connected to each substation 1. Compared with the traditional method of connecting a shore station to an underwater substation 1 through an optoelectronic composite cable, the underwater substation 1 is connected to as many data cabins 3 as possible, that is, the data cabins 3 are arranged in a ring around the underwater substation 1. In this embodiment, the distance between the data cabin 3 and the substation 1 can be greatly reduced, the length of the submarine cable is shortened, and the risk of cross-knotting of the submarine cable is reduced; the number of data cabins 3 that can be laid per unit seabed area is greatly increased, and the longitudinal direction of the sea area is also fully utilized (along the direction of the main submarine cable 2).

[0069] In this embodiment, if Figure 1As shown, there are two power distribution components, and the power distribution components are placed in parallel. During use, by increasing the number of power distribution components, the number of data cabins 3 is increased, and the original circular layout with the substation 1 as the center is changed to the cable layout on both sides of the substation 1. The entire station looks neat and orderly, greatly improving the utilization rate of the sea area. In some other embodiments, the number of power distribution components can also be set to three or four or other numbers, which can be selected according to needs.

[0070] In this embodiment, if Figure 1 As shown, a plurality of data cabins 3 connected to any power distribution component are distributed in two rows on both sides of the power distribution component in this row. As mentioned above, this embodiment changes the original circular layout with the substation 1 as the center to the cable layout on both sides of the substation 1, making the entire station look neat and orderly, greatly improving the utilization rate of the sea area.

[0071] In this embodiment, the number of data cabins 3 arranged on both sides of the substation 1 is the same. Figure 2 In the illustrated embodiment, the number of data cabins 3 arranged on both sides of the substation 1 is three. In some other embodiments, the number of data cabins 3 may also be set to four or other numbers, which can be selected according to the needs.

[0072] In this embodiment, if Figure 2 As shown, any data cabin 3 is individually connected to a sub-sea cable 4, and the other end of the sub-sea cable 4 is connected to the substation 1. Specifically, the data cabin 3 and the substation 1 are both provided with a sub-sea cable end 5, and the sub-sea cable 4 is connected to the sub-sea cable end 5 on the data cabin 3 and the substation 1 respectively.

[0073] By arranging the submarine cable end 5 on both the data cabin 3 and the substation 1, the data cabin 3 can be conveniently connected to the substation 1 through the sub-submarine cable 4. When installing the data cabin 3 underwater, the data cabins 3 are laid out one by one in sequence. Before laying each data cabin 3, the corresponding sub-submarine cable 4 is first picked up from the water, the submarine cable waterproof protection joint is removed, and the submarine cable joint 6 is connected to the data cabin 3 on the installation ship and powered on for testing. The installation is convenient and efficient.

[0074] In this embodiment, if Figure 2 As shown, a submarine cable connector 6 is preset on any substation 1 , and two adjacent substations 1 are electrically connected by the submarine cable connector 6 .

[0075] A submarine cable connector 6 is preset on the substation 1. When installing the substation 1 at the starting end of the power distribution assembly, that is, the first-level substation, the submarine cable connector 6 on the first-level substation is connected to the main submarine cable 2. After the first-level substation 1 is placed, the submarine cable connector 6 of the first-level substation 1 for connecting to the next-level substation is placed at a preset position, and the position coordinates are marked and recorded. When the next-level substation is connected, the next-level substation is connected to the submarine cable connector 6.

[0076] In this embodiment, the large-scale underwater data center also includes a plurality of data cabin basic bases 7, which are arranged on opposite sides of the substation 1, and a plurality of data cabins 3 connected to one side of a substation 1 are placed on the data cabin basic base 7 on this side of the substation 1.

[0077] like Figure 2 As shown, the data cabin basic base 7 is frame-shaped, and several data cabins 3 connected to one side of a substation 1 share one data cabin basic base 7. At this time, the data cabin basic base 7 and the several data cabins 3 arranged thereon constitute a large structure. During layout, it is only necessary to complete the installation connection between the large structures, and there is no need to consider the safety distance between other structures (such as a single data cabin 3), so the space utilization rate is higher.

[0078] The large-scale underwater data center provided in this embodiment is to classify the substation 1. The first-level substation can be connected to the second-level substation, retaining very good scalability. Each first-level substation can be connected to the second-level substation. The size of a single substation 1 can be made small, and there is no need to reserve too many interfaces, nor is there a need for excessive one-time investment in the early stage, and the scalability is good. The substation 1 connected to each main submarine cable 2 and all the data cabin 3 modules connected to the next-level substation are called a station, and the distance between stations is greatly reduced.

[0079] Example 2

[0080] This embodiment provides a method for arranging a large-scale underwater data center, using the large-scale underwater data center in Embodiment 1, and comprising the following steps:

[0081] Step 1: Before laying the first-level substation, first connect the submarine cable connector 6 on the first-level substation to the pre-laid main submarine cable 2, and remotely start the first-level substation to test whether the main submarine cable 2 is well connected;

When the next-level substation is connected, it is connected to the submarine cable connector 6.

[0083] Step 3: Lay out the data cabin base 7 at the predetermined position, and coil all the side cables 4 from the cable coiling rack in turn, and remove the cable coiling rack;

[0084] Step 4: Lay out the data cabins 3 one by one in order. Before laying out each data cabin 3, first pick up the corresponding sub-submarine cable 4 from the water, remove the waterproof protection joint of the submarine cable, connect the submarine cable joint 6 and the data cabin 3 on the installation ship, power on and test them, and then lay them to the underwater data cabin foundation base 7;

[0085] Step 5: When laying the data cabin 3 on the other side, first lay the data cabin base 7, and then coil all the submarine cables 4 on this side from the cable reel rack, remove the cable reel rack, and lay the data cabins 3 one by one in order;

[0086] Step 6: Repeat the above steps when deploying the next-level substation and data cabin 3 modules.

[0087] The large-scale underwater data center layout method provided in this embodiment is to classify the substation 1. The first-level substation can be connected to the second-level substation, retaining very good scalability. Each first-level substation can be connected to the second-level substation. The size of a single substation 1 can be made small, and there is no need to reserve too many interfaces, nor is there a need for excessive initial one-time investment, and the scalability is good. The substation 1 connected to each main submarine cable 2 and all the data cabin 3 modules connected to the next-level substation are called a station.

For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
