Description

Technical Field

[0001] This invention relates to the field of shipboard storage technology for underwater devices of submarine communication optical cables, specifically a submarine optical cable repeater storage box and its installation method. Background Technology

[0002] In submarine communication networks, optical fiber repeaters play a crucial role. They are responsible for receiving, amplifying, and retransmitting optical signals to ensure that the signals do not attenuate during long-distance optical cable transmission. These repeaters are usually assembled in specific locations in the submarine optical cable system to relay signals when needed.

[0003] Given the long-term and continuous nature of submarine cable-laying operations, storing a certain number of repeaters on the cable-laying vessel requires consideration of requirements such as cold insulation, prevention of mechanical damage, and convenient access. Traditional storage methods often cannot meet these needs. For example, simply stacking repeaters in the work compartment may cause them to be heated, damaged, or subject to other environmental factors. In addition, repeaters are generally large in size and numerous, but ship space is limited, so how to effectively store and manage repeaters in a limited space is also a challenge.

[0004] Document CN202320145198 discloses a marine relay container, comprising: a container body; side supports located on both sides inside the container body, a central support located in the middle of the container body, and a support frame connecting the upper ends of the side supports and the upper ends of the central support; multiple bases located at the bottom of the container body, each base having an upper inclined surface on its upper surface, with two adjacent upper inclined surfaces facing each other, and a repeater arranged between two adjacent upper inclined surfaces; and fixed seats located on the side supports or the central support, each fixed seat having an upper inclined surface on its upper surface and a lower inclined surface on its lower surface, with a repeater arranged between two adjacent upper inclined surfaces and between two adjacent lower inclined surfaces. This structure allows for the storage of repeaters in a straight line between adjacent repeaters, thus reducing the number of repeaters that can be stored.

[0005] Therefore, a new technical solution is needed to solve the above-mentioned technical problems. Summary of the Invention

[0006] To address the aforementioned issues, this invention discloses a submarine optical cable repeater storage box and its installation method. The storage box has a detachable structure and can be converted into a common area inside the cabin for other purposes when it is not needed to store repeaters, so as to make full use of the space resources on board and to store and manage more repeaters in a limited space, thereby improving access efficiency and work efficiency.

[0064] The advantages of this invention are: 1. The storage box of this invention is divided into two groups, one with three layers and the other with two layers. The internal structure of the storage box can be flexibly adjusted according to the actual number of repeaters, so that it can be used for different numbers of repeaters, saving construction time and improving work efficiency.

[0065] 2. The No. 1 and No. 2 partitions of this invention can be used to insert the perforated plate into the groove of the column according to the actual situation, and the perforated plate inserted into the groove can be pulled out for disassembly according to the usage situation. It is flexible in use, can adapt to different numbers of repeaters, and is convenient to use.

[0066] 3. Except for the base, the entire structure of the storage box of this invention is detachable, and it can be converted into a public area inside the cabin when it is not needed to store repeaters, making full use of the space resources on the ship and improving the functionality and flexibility of the ship.

[0067] 4. In this invention, the first partition and the first reverse partition are arranged in opposite directions, and the second partition and the second reverse partition are arranged in opposite directions, that is, the long plates are placed alternately. In this way, when placing repeaters, they can also be placed alternately, increasing the number of repeaters that can be stored.

[0086] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0087] like Figure 1 As shown, a submarine optical cable repeater storage box includes a box body bolted to the upper surface of a deck. The box body includes longitudinal partitions located between outer partitions. The top and sides of the longitudinal partitions are respectively provided with a top plate 30 and side panels 20. The side panels 20 are typically made of waterproof and heat-insulating materials to protect the internal equipment from environmental influences. The top plate 30 is used to enclose and cover the top of the box body. The top plate 30 is made of a material with heat-insulating and insulating properties, such as aluminum honeycomb panels, to maintain a constant temperature inside the storage box. The storage box has eight longitudinal partitions for... The storage box is divided into different storage areas to accommodate multiple repeaters or branch units. The partitions are removable, allowing for adjustments to the internal layout of the storage box as needed. The partitions feature a heat-insulating design, and the top 30 and side panels 20 of the storage box are insulated with aluminum honeycomb panels to maintain a constant internal storage temperature of 15±3℃. The aluminum honeycomb panels have excellent heat insulation and corrosion resistance, effectively preventing external temperature changes from affecting the repeaters. The two outermost longitudinal panels 40 have several vertically penetrating rectangular gaps to ensure cables can pass through the storage box.

[0088] like Figure 2-5 As shown, the enclosure is arranged in three-layer and two-layer configurations from bottom to top. The longitudinal partitions include partition 50 (first layer), partition 60 (second layer), partition 70 (reverse first layer), and partition 80 (reverse second layer). Partition 70 has three or four layers, each fixed by a groove inserted into the upright 71. Similarly, partition 60 has three or four layers, each fixed by a groove in the upright 71. The storage enclosure is divided into two groups, one with three layers and the other with two layers. Each layer can accommodate two rows of repeaters, with six repeaters 90 per row. To maximize space utilization, the terminals of the two rows of repeaters 90 are arranged in a cross pattern. This minimizes the gaps between repeaters 90. There are 10 partitions along the longitudinal direction of the repeater. The two outermost partitions facilitate the passage of optical cables connected at both ends, while the eight middle partitions are used to fix the repeater. To fit the shape of the repeater 90, the gap in the first partition 50 is used to place the lead wires at both ends of the repeater and the connecting optical cables, while the large round hole 65 in the second partition 60 is used to place the rigid part 67 in the middle section of the repeater. The internal structure of the storage box can be flexibly adjusted according to the actual number of repeaters 90, making it suitable for different numbers of repeaters 90, saving construction time and improving work efficiency.

[0089] Reverse partition 1 70 and reverse partition 2 80 are assembled in reverse order of partition 1 50 and partition 2 60 along any of their vertical sides as the axis of symmetry. In the box, partition 1 50 and partition 2 60, as well as reverse partition 1 70 and reverse partition 2 80 are arranged in sequence to form the box.

[0090] like Figure 2As shown, the bottom and top layers of the first partition 50, from one side to the other, are a unidirectional semi-long waist-shaped perforated plate 51, a unidirectional semi-short waist-shaped perforated plate 52, and a unidirectional semi-short waist-shaped perforated plate 53, respectively. The middle layer of the first partition is one or two layers, from one side to the other, which are a bidirectional semi-long waist-shaped perforated plate 53, a bidirectional semi-short waist-shaped perforated plate 54, and a bidirectional semi-short waist-shaped perforated plate 54, respectively. The outermost unidirectional semi-long waist-shaped perforated plates 51 and unidirectional semi-short waist-shaped perforated plates 52 of the upper and lower layers are arranged opposite each other. Any number of bidirectional perforated plates can be arranged between the unidirectional perforated plates, and a corresponding complete waist-shaped hole is formed between the unidirectional and bidirectional perforated plates.

[0091] A complete elongated through hole is formed at the grooves between the two sides of the bidirectional semi-elongated waist-shaped perforated plate 53 and the unidirectional semi-elongated waist-shaped perforated plate 51 or the bidirectional semi-elongated waist-shaped perforated plate 53. A complete short waist-shaped through hole is formed at the grooves between the two sides of the bidirectional semi-short waist-shaped perforated plate 54 and the unidirectional semi-short waist-shaped perforated plate 52 or the bidirectional semi-short waist-shaped perforated plate 54. The transverse length of the elongated through hole is greater than that of the short waist-shaped through hole. The semi-waist-shaped perforated plates are all half the size of the waist-shaped perforated plates. When the two are combined, they form a complete waist-shaped hole.

[0092] like Figure 3 As shown, the bottom and top layers of the second partition 60, from one side to the other, are a unidirectional semi-circular hole long plate 61, a unidirectional semi-circular hole short plate 62, and a unidirectional semi-circular hole short plate 62, respectively. The middle layer of the second partition 60 is one or two layers, from one side to the other, which are a bidirectional semi-circular hole long plate 63, a bidirectional semi-circular hole short plate 64, and a bidirectional semi-circular hole short plate 64, respectively. A large circular hole is formed between the semi-circular hole plates. The upper and lower layers are unidirectional semi-circular plates placed opposite each other, and the bidirectional hole plate and the unidirectional hole plate in the middle form a complete large circular hole.

[0093] The distance between the outer center of the unidirectional semi-circular hole long plate 61 and the bidirectional semi-circular hole long plate 63 and the C-shaped column 71 is greater than the distance from the center of the unidirectional semi-circular hole short plate and the bidirectional semi-circular hole short plate to the I-shaped slot column 72. Small semi-circular holes 661 are provided on both sides of the semi-circular grooves of the unidirectional semi-circular hole long plate 61, the unidirectional semi-circular hole short plate 62, the bidirectional semi-circular hole long plate 63, and the bidirectional semi-circular hole short plate 64. Large circular holes 65 are formed on both sides of the bidirectional semi-circular hole long plate 63 with either the unidirectional semi-circular hole long plate 61 or the bidirectional semi-circular hole long plate 63. Large circular holes 65 are formed on both sides of the bidirectional semi-circular hole short plate 64 with either the unidirectional semi-circular hole short plate 62 or the bidirectional semi-circular hole short plate 64. Small circular holes 66 are formed between the small semi-circular holes 661, and the small circular holes 66 are located within the large circular holes. On both sides of 65, small round holes 66 are located at the horizontal position where the large round hole 65 passes through the center. The thickness of the large round hole 65 is greater than that of other positions of the second partition 60. The surfaces of both the large round hole 65 and the small round hole are covered with rubber to facilitate the safe passage of optical cables from this layer connected to the opposite repeater 90. A small hole 69 is provided between two adjacent small round holes 66. Longer optical cables can be hung on this small hole 69 after being wound up. The terminals at both ends of the repeater 90 connected to the optical cable are relatively flexible. When the repeater 90 is placed horizontally, the terminals at both ends will hang down naturally, and the terminal parts pass through the gaps in the first partition 50. The gaps in the first partition 50 are also covered with rubber. The rubber layer serves to reduce the impact on the repeater and increase friction to improve the stability of the repeater 90.

[0094] The outermost columns of partition 1 50 and partition 2 60 are C-shaped slot columns 71, which are arranged opposite each other. The two columns in the middle are I-shaped slot columns 72. The outermost columns of partition 1 50 and partition 2 60 use C-shaped slot columns 71, and the middle columns use I-shaped slot columns 72, which are used to engage the perforated plates on both sides.

[0095] The ends of the C-type slot column 71 and the I-type slot column 72 are flush with the perforated plates according to the number of perforated plates placed.

[0096] Figure 6 This is a schematic diagram of the repeater storage plan for each layer of the repeater storage box. Each layer can accommodate two rows of repeaters, with six repeaters in each row. The terminals of the two rows of repeaters are arranged in a cross pattern to make full use of the space. A left terminal of a repeater from the right row is inserted between the right terminals of every two repeaters in the left row. This maximizes the saving of space on the ship and ensures that as many repeaters as possible can be stacked while occupying the same amount of space.

[0097] An installation method for a submarine optical cable repeater storage box includes the following steps:

[0098] The cabinet has two-layer and three-layer repeater stacking forms. Each layer can hold 6 repeaters on the left and right, for a total of 12 repeaters.
