Description

Technical Field

[0001] The present application relates to the technical field of submarine cable armoring, and in particular to a submarine cable armor casing device. Background Art

[0002] With the growing demand for seabed exploration, communications, and energy transmission, submarine cables face increasingly diverse and demanding operating environments. This is especially true for cables already buried in the seabed. As the ground erodes due to currents, geological changes, or human activities, some cables become exposed or even become suspended. This makes them susceptible to vibrations caused by ocean currents, which can lead to bending and failure due to their own gravity, or external damage such as anchor damage and fish bites, seriously affecting the service life and safety of the submarine cables.

[0003] Existing submarine cable armoring or protection methods typically lack modular expansion and extension capabilities. As the exposed cable length increases, the original armored casing can no longer fully protect the cable, necessitating removal and replacement, resulting in high maintenance and replacement costs. Some modular casings attempt to achieve splicing and extension through threaded connections or external fasteners, but installation requires specialized tools and precise operation, placing high demands on divers or underwater robots, making installation difficult and limiting efficiency. Summary of the Invention

[0004] The present application aims to solve at least one of the technical problems existing in the prior art. To this end, the present application proposes a submarine cable armor casing device that can meet the requirements of casing extension installation, reduce maintenance costs and installation difficulty, and improve installation convenience and economy.

[0005] The submarine cable armor casing device according to an embodiment of the present application includes:

[0006] The housing comprises a first shell and a second shell arranged at intervals, wherein the first shell and the second shell are both provided with an installation cavity and a first opening communicating with the installation cavity;

[0007] a first barrel assembly, mounted in the mounting cavity of the first housing;

[0008] a second barrel assembly installed in the installation cavity of the second housing, wherein the first barrel assembly and the second barrel assembly each include a plurality of barrel pieces sequentially arranged along a second direction;

[0009] an opening and closing mechanism for driving the first shell and the second shell to move away from or toward each other to open the outer shell, or to close the outer shell so that the barrels of the first barrel group and the second barrel group are connected and enclosed to form a barrel column;

[0010] a first pushing mechanism for pushing the tube pieces to move and splice along a first direction, and pushing the tube pieces out of the housing through the first opening;

[0011] The second pushing mechanism is used to push the first barrel group and the second barrel group along the second direction.

[0012] The submarine cable armor casing device according to the embodiment of the present application has at least the following beneficial effects: by setting an opening and closing mechanism to drive the first shell and the second shell to move away from or approach each other, so as to open or close the outer shell, the submarine cable can enter between the first shell and the second shell when the outer shell is opened, and then the outer shell is closed so that the barrel pieces of the first barrel group and the second barrel group are connected and enclosed to form a barrel column. At this time, the barrel column surrounds the outer periphery of the submarine cable to achieve the effect of protecting the submarine cable. At the same time, the current barrel piece is moved in the first direction to a vacant position by the first pushing mechanism, and then the second pushing mechanism is used to push the second barrel piece in the second direction. The first barrel group and the second barrel group enable the barrel pieces of the first barrel group and the second barrel group to be moved to the position of the original barrel piece to supplement the barrel piece, and then the newly supplemented barrel piece is pushed by the first pushing mechanism to be spliced ​​with the previous barrel piece along the first direction, so that the length of the barrel column along the first direction is extended and lengthened. When the length of the barrel column is long enough, the first pushing mechanism can push the barrel piece out of the shell from the first opening and leave the installation position of the next barrel piece vacant to facilitate the splicing of the barrel pieces. The extension and lengthening of the barrel column is achieved through the cooperation of the first pushing mechanism and the second pushing mechanism, and finally a casing surrounding the outer periphery of the submarine cable is formed. It can be seen that the submarine cable armor casing device of the present application can meet the requirements of casing extension installation without the need for divers or underwater robots to operate, which is conducive to reducing maintenance costs and installation difficulty, and improving installation convenience and economy.

[0046] The contents of this application are described in detail below in conjunction with specific embodiments. It should be noted that the following description is only for illustrative purposes and is not a specific limitation to this application.

[0047] Please refer to Figure 1 , see also Figures 2 to 5, an embodiment of the present application provides a submarine cable armor casing device 1, including an outer shell 11, a first barrel group 12, a second barrel group 13, an opening and closing mechanism 14, a first pushing mechanism 15 and a second pushing mechanism 16. The outer shell 11 includes a first shell body 111 and a second shell body 112 arranged at intervals. The first shell body 111 and the second shell body 112 are both provided with an installation cavity and a first opening 1110 communicating with the installation cavity. The first barrel group 12 is installed in the installation cavity of the first shell body 111, and the second barrel group 13 is installed in the installation cavity of the second shell body 112. The first barrel group 12 and the second barrel group 13 both include a plurality of barrel sheets arranged in sequence along the second direction y. The opening and closing mechanism 14 is used to drive the first shell body 111 and the second shell body 112 to move away from or approach each other to open the outer shell 11, or to close the outer shell 11 so that the barrel sheets of the first barrel group 12 and the second barrel group 13 are connected and enclosed to form a barrel column. The first pushing mechanism 15 is used to push the barrel pieces to move and splice along the first direction x and push the barrel pieces out of the housing 11 through the first opening 1110 . The second pushing mechanism 16 is used to push the first barrel assembly 12 and the second barrel assembly 13 along the second direction y.

[0048] The submarine cable armor casing device 1 of the embodiment of the present application drives the first shell 111 and the second shell 112 to move away from or approach each other by setting an opening and closing mechanism 14 to open or close the outer shell 11. When the outer shell 11 is opened, the submarine cable can enter between the first shell 111 and the second shell 112. Then, the outer shell 11 is closed so that the barrel pieces of the first barrel group 12 and the second barrel group 13 are connected and enclosed to form a barrel column. At this time, the barrel column surrounds the outer periphery of the submarine cable 2 to achieve the effect of protecting the submarine cable 2. At the same time, the current barrel piece is moved to a vacant position along the first direction x by the first pushing mechanism 15, and then the first barrel is pushed along the second direction y by the second pushing mechanism 16. The first barrel group 12 and the second barrel group 13 enable the barrel pieces of the first barrel group 12 and the second barrel group 13 to be moved to the position of the original barrel piece to supplement the barrel piece, and then the first pushing mechanism 15 pushes the newly supplemented barrel piece to be spliced ​​with the previous barrel piece along the first direction x, so that the length of the barrel column along the first direction x is extended and lengthened. When the length of the barrel column is long enough, the first pushing mechanism 15 can push the barrel piece out of the housing 11 from the first opening 1110, and vacate the installation position of the next barrel piece to facilitate the splicing of the barrel piece. The first pushing mechanism 15 and the second pushing mechanism 16 cooperate to achieve the extension and lengthening of the barrel column, and finally form a casing surrounding the outer periphery of the submarine cable. Therefore, the need for extending and installing the casing can be met without the operation of divers or underwater robots, which is conducive to reducing maintenance costs and installation difficulty, and improving installation convenience and economy.

[0049] Please combine Figures 6 to 8In some embodiments, the first barrel group 12 includes a first barrel piece 121 and a second barrel piece 122 arranged in sequence along the second direction y, the first barrel piece 121 is provided with a first tenon 1221, the first tenon 1221 is used for mortise and tenon connection with the first tenon groove 1211, the first tenon groove 1211 is provided with a first clamping portion 1212, the first tenon 1221 is provided with a second clamping portion 1222, the first clamping portion 1212 and / or the second clamping portion 1222 are movable along a third direction z so that the first clamping portion 1212 and the second clamping portion 1222 can be clamped or unlocked with each other, and the third direction z is perpendicular to the first direction x.

[0050] In this way, by setting two cylinder pieces and connecting them through mortise and tenon, the cylinder pieces are spliced ​​and positioned, which is beneficial to the matching connection between multiple cylinder pieces. At the same time, by setting the first clamping part 1212 and the second clamping part 1222 for snap connection, the two cylinder pieces of the first cylinder group 12 are locked after being spliced, so as to avoid the cylinder pieces from becoming loose or falling off.

[0051] Optionally, as can be seen from the above, when the first shell 111 and the second shell 112 are brought close to each other to close the outer shell 11, the tube pieces of the first tube group 12 and the second tube group 13 are connected and enclosed to form a tube column, and the tube pieces of the first tube group 12 are spliced ​​along the first direction x, and the tube pieces of the second tube group 13 are spliced ​​along the first direction x. Based on this, the third direction z is perpendicular to the first direction x and the second direction y, so that the spliced ​​casing can be locked along different directions, thereby improving the structural reliability of the casing, thereby improving the protection effect of the submarine cable and ensuring the safety of the submarine cable.

[0052] It can be understood that in other embodiments, the third direction z may also be parallel to the second direction y.

[0053] Please combine Figure 7 as well as Figures 9 to 11 In some embodiments, the first clamping portion 1212 and the second clamping portion 1222 include an active clamping portion 12122 and an elastic member 12123. The first cylinder piece 121 is provided with a first mounting groove at the first tenon groove, and the second cylinder piece 122 is provided with a second mounting groove at the first tenon. The active clamping portion 12122 can be movably installed in the first mounting groove or the second mounting groove. The elastic member 12123 is connected to the active clamping portion 12122 and is used to drive the active clamping portion 12122 to extend from the first mounting groove or the second mounting groove. When the first cylinder piece 121 and the second cylinder piece 122 are spliced, the first mounting groove is aligned or roughly aligned with the second mounting groove, and the active clamping portion 12122 of the first clamping portion 1212 pops out and extends into the second mounting groove, and the active clamping portion 12122 of the second clamping portion 1222 pops out and extends into the first mounting groove.

[0054] In this way, after the first clamping portion 1212 and the second clamping portion 1222 are clamped and locked, the first tenon 1221 is inserted into the first tenon groove 1211, and the second cylinder piece 122 cannot move forward along the first direction x (i.e., the direction close to the first cylinder piece 121) under the restriction of the first tenon groove 1211. When the second cylinder piece 122 moves backward along the first direction x (i.e., the direction away from the first cylinder piece 121), the movable clamp 12122 of the first clamping portion 1212 and the movable clamp 12122 of the second clamping portion 1222 conflict with each other, so that the first clamping portion 1212 and the second clamping portion 1222 are clamped together, and the first tenon 1221 cannot fall out of the first tenon groove 1211, so as to ensure the splicing reliability of the second cylinder piece 122 and the first cylinder piece 121, and avoid the second cylinder piece 122 and the first cylinder piece 121 from loosening and falling off.

[0055] Optionally, the elastic member 12123 may be any one of a compression spring, a tension spring or a spring sheet.

[0056] As an alternative embodiment, the elastic member 12123 may also be replaced by a telescopic rod or a cylinder.

[0057] Optionally, the first clamping portion 1212 and the second clamping portion 1222 further include a fixing seat 12121, the fixing seat 12121 is installed in the first mounting groove or the second mounting groove, the fixing seat 12121 is provided with an activity space and a first activity hole 12121a and a second activity hole 12121b communicating with the activity space, the movable buckle 12122 is movably installed in the activity space, so that the size of the movable buckle 12122 extending out of the first activity hole 12121a or the second activity hole 12121b is adjustable, one end of the elastic member 12123 is connected to the inner wall of the activity space, and the other end of the elastic member 12123 is connected to the movable buckle 12122 away from the first activity hole 12121a At one end, the movable clip 12122 is used to shrink into the active space when the second cylinder piece 122 moves along the first direction x towards the first cylinder piece 121. When the first cylinder piece 121 and the second cylinder piece 122 are spliced ​​to the first clamping portion 1212 and are aligned or roughly aligned with the second clamping portion 1222, the movable clip 12122 of the first clamping portion 1212 pops out of the first active hole 12121a and extends into the active space of the second clamping portion 1222 under the drive of the elastic member 12123. The movable clip 12122 of the second clamping portion 1222 pops out of the first active hole 12121a and extends into the active space of the first clamping portion 1212 under the drive of the elastic member 12123.

[0058] Optionally, the movable buckle 12122 includes a main body 12122a, a limiting portion 12122b and a connecting portion 12122c, the main body 12122a is a semi-cylindrical structure, the limiting portion 12122b is connected to the arc edge of the main body 12122a, and the thickness of the limiting portion 12122b is greater than the thickness of the main body 12122a, the connecting portion 12122c is arranged on the side of the limiting portion 12122b away from the main body 12122a, the fixed seat 12121 is provided with a movable track 12121c connected to the movable space, the main body 12122a is movably installed in the movable space, the limiting portion 12122b is movably installed on the movable track 12121c, and the limiting portion 12122b and the elastic member 12123 are movably passed through the second movable hole 12121b. In the initial state where the tube pieces are not spliced ​​together, the main body 12122a and the limiting portion 12122b partially extend out of the first movable hole 12121a, the straight edge of the main body 12122a faces the adjacent tube piece, and the elastic member 12123 is in a natural state without being subject to external force. For example, in the process of the second cylinder piece 122 moving toward the first cylinder piece 121 for splicing, when the first tenon 1221 of the second cylinder piece 122 is not inserted into the first tenon groove 1211 of the first cylinder piece 121, the cylinder piece is in an initial state of not being spliced, the main body 12122a and the limiting portion 12122b of the first clamping portion 1212 partially extend out of the first movable hole 12121a, and the straight edge of the main body 12122a faces the direction of the second cylinder piece 122. When the second cylinder piece 122 moves toward the first cylinder piece 121 until the first tenon 1221 is gradually inserted into the first tenon groove 1211, the main body 12122a and the limiting portion 12122b push the first tenon 1221 of the second cylinder piece 122 The downward movement shrinks in the fixed seat 12121, and the elastic member 12123 generates compression deformation and elastic restoring force as the connecting portion 12122c moves, until the second cylinder piece 122 moves to the point where the first clamping portion 1212 is aligned or roughly aligned with the second clamping portion 1222, the main body 12122a and the limiting portion 12122b are reset under the action of the elastic restoring force, so that the movable buckle 12122 of the first clamping portion 1212 is partially inserted into the active space of the second clamping portion 1222, and the movable buckle 12122 of the second clamping portion 1222 is partially inserted into the active space of the first clamping portion 1212, thereby completing the splicing of the first cylinder piece 121 and the second cylinder piece 122 along the first direction x.

[0059] In this way, the movement direction of the movable buckle 12122 in the fixed seat 12121 is limited by the limiting portion 12122b, and the movement stroke of the movable buckle 12122 is limited by the connecting portion 12122c and the second movable hole 12121b. At the same time, the connecting portion 12122c is pulled by the elastic member 12123, which can not only limit the movement stroke of the movable buckle 12122, but also provide elastic restoring force for the movable buckle 12122 when the first clamping portion 1212 and the second clamping portion 1222 are aligned, so that the first clamping portion 1212 and the second clamping portion 1222 can be clamped or unlocked with each other to complete the clamping connection between the first cylinder piece 121 and the second cylinder piece 122.

[0060] It is understandable that, as an alternative embodiment, one of the first clamping portion 1212 and the second clamping portion 1222 may be a movable clamping structure, and the other may be a groove.

[0061] Optionally, a first tenon 1221 is provided at one end of the first barrel piece 121 and the second barrel piece 122 along the first direction x, and a first tenon groove 1211 is provided at the other end of the first barrel piece 121 and the second barrel piece 122 along the first direction x. This allows the first barrel piece 121 and the second barrel piece 122 to have the same structural shape, which is beneficial to the design and manufacture of the barrel pieces. At the same time, since two adjacent barrel pieces are positioned by the mortise and tenon connection and are snap-connected by the first clamping portion 1212 and the second clamping portion 1222, and the tenon and tenon groove are provided at both ends of the barrel piece, respectively, it is possible to facilitate the front-to-back splicing of two adjacent barrel pieces, facilitate continuous splicing of the barrel pieces, and improve the convenience of extending the casing.

[0062] As an alternative embodiment, the first tube piece 121 and the second tube piece 122 may be connected by magnetic attraction through a magnetic member.

[0063] Please combine Figure 5 、 Figure 6 and Figure 12 Optionally, the second barrel assembly 13 includes a third barrel piece 131 and a fourth barrel piece 132 sequentially arranged along the second direction y. A first tongue and groove 1211 is provided at one end of the third barrel piece 131 and the fourth barrel piece 132 along the first direction x, and a first tenon 1221 is provided at the other end of the third barrel piece 131 and the fourth barrel piece 132 along the first direction x. The first tongue and groove 1211 is provided with a first clamping portion 1212, and the first tenon 1221 is provided with a second clamping portion 1222. This facilitates the positioning of the barrel pieces and locks the two barrel pieces of the second barrel assembly 13 after being spliced, preventing the barrel pieces from becoming loose or falling off.

[0064] The splicing method of the barrel pieces of the second barrel group 13 is the same as that of the barrel pieces of the first barrel group 12, and will not be repeated here.

[0065] It should be noted that the first barrel group 12 can only be provided with the first barrel piece 121 and the second barrel piece 122, and the second barrel group 13 can only be provided with the third barrel piece 131 and the fourth barrel piece 132, or the first barrel group 12 and the second barrel group 13 can also include a plurality of barrel pieces arranged in sequence along the second direction y so that the protective barrel can be extended to the target length.

[0066] For ease of reading and understanding, the first tube piece 121 is defined as being located on the side of the second tube piece 122 close to the second tube group 13, and the third tube piece 131 is defined as being located on the side of the fourth tube piece 132 close to the first tube group 12. The structure of the submarine cable armored casing device 1 is further described below based on this.

[0067] In some embodiments, the side of the tube piece facing the submarine cable is detachably connected to a liner. By setting the liner, the size of the tube column formed by the connection of the tube pieces can be adjusted to adapt to submarine cables of different diameters, which is beneficial to improving the versatility of the submarine cable armored tube device 1.

[0068] Please combine Figure 3 、 Figure 5 as well as Figures 13 and 14 In some embodiments, a first fixed stopper 113 is provided on a side of the first shell 111 close to the second shell 112, and a second fixed stopper 114 is provided on a side of the second shell 112 close to the first shell 111. The shapes of the first fixed stopper 113 and the second fixed stopper 114 match the shape of the tube sheet, and the tube sheet fits with the first fixed stopper 113 or the second fixed stopper 114 and is pushed out of the shell 11 from the first opening 1110.

[0069] In this way, by providing the first fixed stopper 113 and the second fixed stopper 114 to position the cylinder, it is possible to facilitate the connection of the cylinders of the first cylinder group 12 and the second cylinder group 13, and to facilitate guiding the movement of the cylinder when the cylinder moves along the first direction x, preventing the cylinder from flipping relative to the first fixed stopper 113 or the second fixed stopper 114, thereby ensuring that the cylinder can be pushed out of the housing 11 through the first opening 1110. In addition, by providing the first fixed stopper 113 and the second fixed stopper 114, the movement distance of the cylinder can be limited when the second pushing mechanism 16 pushes the cylinder along the second direction y, thereby limiting the position of the cylinder, allowing the cylinder to move along the second direction y until it abuts against the first fixed stopper 113 or the second fixed stopper 114, so that it can be pushed out of the housing 11 through the first opening 1110 under the push of the first pushing mechanism 15.

[0070] Optionally, the first fixed block 113 and the second fixed block 114 extend along the first direction x, one end of the first fixed block 113 is connected to the inner wall of the first shell 111 away from the first opening 1110, and the other end of the first fixed block 113 extends out of the first shell 111 from the side of the first shell 111 close to the first opening 1110, one end of the second fixed block 114 is connected to the inner wall of the second shell 112 away from the first opening 1110, and the other end of the second fixed block 114 extends out of the second shell 112 from the side of the second shell 112 close to the first opening 1110. In this way, when the tube piece extends out of the shell 11 from the first opening 1110, it can be supported by the first fixed block piece 113 and the second fixed block piece 114, which is conducive to limiting the tube column and preventing the tube column formed by the connection and enclosure of the first tube piece 121 and the third tube piece 131 from moving downward under the action of gravity, thereby facilitating the alignment accuracy of the second tube piece 122 when splicing with the first tube piece 121 along the first direction x, and the alignment accuracy of the fourth tube piece 132 when splicing with the third tube piece 131 along the first direction x, thereby facilitating the splicing of the tube pieces and facilitating the extension of the length of the protective tube.

[0071] Optionally, the first fixed block 113 is connected to the first shell 111, and a first sliding groove 1111 is provided between the first fixed block 113 and the first shell 111. The second fixed block 114 is connected to the second shell 112, and a second sliding groove 1121 is provided between the second fixed block 114 and the second shell 112. The first sliding groove 1111 and the second sliding groove 1121 extend along the first direction x and are connected to the first opening 1110. The first cylinder piece 121 and the second cylinder piece 122 are provided with a first matching portion 123, and the first matching portion 123 is provided corresponding to the first sliding groove 1111. The third cylinder piece 131 and the fourth cylinder piece 132 are provided with a second matching portion 133, and the second matching portion 133 is provided corresponding to the second sliding groove 1121. The first matching portion 123 and the second matching portion 133 are in contact and connected with the second sliding groove 1121 through the first sliding groove 1111.

[0072] In this way, by providing the first sliding groove 1111 and the second sliding groove 1121, on the one hand, the first matching portion 123 and the second matching portion 133 can be avoided to ensure that the first barrel group 12 and the second barrel group 13 will not produce structural interference when the shell 11 is closed, so as to improve the structural reliability of the submarine cable armored casing device 1. On the other hand, the first barrel group 12 and the second barrel group 13 can be moved to the target position under the drive of the opening and closing mechanism 14, so that the first barrel piece 121 and the third barrel piece 131 can be connected and enclosed to form a barrel column surrounding the outer periphery of the submarine cable when the shell 11 is closed, which is conducive to ensuring that the casing remains closed, thereby improving the protection effect of the casing on the submarine cable and improving the connection reliability of the casing. At the same time, it is also conducive to making the barrel pieces of the first barrel group 12 and the second barrel group 13 consistent with the position in the shell 11 when they are pushed out of the shell 11, so as to improve the position stability of the barrel pieces, thereby facilitating the splicing of the barrel pieces along the first direction x and facilitating the splicing extension of the casing.

[0073] Please combine Figure 7 、 Figure 8 as well as Figures 13 and 14 Optionally, the first matching portion 123 is snap-connected with the second matching portion 133, one of the first matching portion 123 and the second matching portion 133 is a protrusion structure, and the other is a groove structure, the protrusion structure includes a first protrusion and a second protrusion, the second protrusion is connected to the end of the first protrusion away from the cylinder sheet, the size of the second protrusion is larger than the first protrusion, the protrusion structure extends out of the first slide groove 1111 or the second slide groove 1121, the opening size of the groove structure is smaller than the maximum size of the groove structure, the groove structure passes through both sides of the cylinder sheet along the first direction x, and the first cylinder group 12 is staggered with the second cylinder group 13 along the first direction x.

[0074] In this way, by setting the protrusion structure to include two protrusions of different sizes, the opening size of the groove structure is smaller than the maximum size of the groove structure, so that after the protrusion structure enters the groove structure, it remains stably connected along the opening direction of the groove structure, which is beneficial to avoiding the protrusion structure from falling out of the groove structure. At the same time, since the groove structure passes through both sides of the cylinder piece along the first direction x, by setting the protrusion structure to extend out of the first slide groove 1111 or the second slide groove 1121, and the first cylinder group 12 is staggered with the second cylinder group 13 along the first direction x, it can be ensured that there is no structural interference between the cylinder pieces of the first cylinder group 12 and the second cylinder group 13 when the shell 11 is closed. The first pushing mechanism 15 pushes the cylinder piece located at the rear in the first direction x, so that the protrusion structure enters the groove structure from one side of the cylinder piece and remains stably connected with the groove structure, so as to realize the snap connection between the first matching portion 123 and the second matching portion 133, so that the two cylinder pieces are firmly connected along the second direction y, so as to improve the structural reliability of the cylinder column.

[0075] Optionally, the cylinder piece is a semicircular structure, and a first matching portion 123 and a second matching portion 133 are respectively provided at both ends of the cylinder piece in the circumferential direction centered on the first direction x, so that the two cylinder pieces can be connected to form a stable columnar structure when docked along the second direction y, thereby improving the structural reliability of the casing.

[0076] It can be understood that, as an alternative, in other embodiments, the first fitting portion 123 and the second fitting portion 133 may also be magnetic parts, so that the cylinder pieces of the first cylinder group 12 and the cylinder pieces of the second cylinder group 13 are connected by magnetic attraction, or the first fitting portion 123 and the second fitting portion 133 may also be adhesive parts, so that the cylinder pieces of the first cylinder group 12 and the cylinder pieces of the second cylinder group 13 are connected by adhesive.

[0077] In some embodiments, the first fixed baffle 113 and the second fixed baffle 114 are provided with a first positioning portion 1131, and the cylinder is provided with a second positioning portion 1213. The first positioning portion 1131 and the second positioning portion 1213 extend along the first direction x, and the second positioning portion 1213 and the first positioning portion 1131 cooperate with each other and are engaged with each other, wherein one of the first positioning portion 1131 and the second positioning portion 1213 is a ridge, and the other is a groove.

[0078] In this way, on the one hand, the displacement of the barrel can be limited along the circumference of the submarine cable, thereby improving the position stability of the barrel in the first shell 111 and the second shell 112, and avoiding the situation where the barrel escapes from the first slide groove 1111 or the second slide groove 1121 and affects the connection between the first matching part 123 and the second matching part 133, so as to improve the reliability of the submarine cable armor casing device 1. On the other hand, the movement direction of the barrel can be limited when the barrel moves along the first direction x, so as to guide the barrel to move horizontally along the first direction x and out of the outer shell 11, which is beneficial to avoid the barrel from unilaterally tilting and displacing due to uneven thrust, resulting in the barrel being unable to be smoothly pushed out of the outer shell 11 from the first opening 1110.

[0079] Optionally, the inner walls of the first shell 111 and the second shell 112 are each provided with a third positioning portion, and the cylinder is provided with a fourth positioning portion. The third positioning portion and the fourth positioning portion extend along the second direction y and engage with each other. One of the third positioning portion and the fourth positioning portion is a ridge, and the other is a groove. This can limit the circumferential movement of the cylinder along the submarine cable and prevent the cylinder from flipping relative to each other within the first shell 111 or the second shell 112, thereby pushing down an adjacent cylinder.

[0080] Please refer again Figures 2 to 6In some embodiments, as can be seen from the above, the first barrel group 12 is staggered with the second barrel group 13 along the first direction x, and the barrel pieces of the first barrel group 12 and the barrel pieces of the second barrel group 13 are snap-connected by moving along the first direction x. Based on this, the number of the first pushing mechanisms 15 is two, and the two first pushing mechanisms 15 are respectively connected to the first shell 111 and the second shell 112. The first pushing mechanism 15 is used to push the barrel pieces of the first barrel group 12 or the barrel pieces of the second barrel group 13 to move along the first direction x.

[0081] By setting up two first pushing mechanisms 15, the cylinder pieces of the first cylinder group 12 and the cylinder pieces of the second cylinder group 13 can be moved respectively along the first direction x, which is conducive to improving the flexibility of the movement of the cylinder pieces, facilitating the coordinated connection between the cylinder pieces of the first cylinder group 12 and the cylinder pieces of the second cylinder group 13, and at the same time facilitating the control of the distance moved by the cylinder pieces of the first cylinder group 12 and the cylinder pieces of the second cylinder group 13 along the first direction x, so as to make room for the cylinder pieces to move along the second direction y.

[0082] Optionally, the first pushing mechanism 15 includes a first push rod 151, a first driving member 152, a first transmission gear 153, and a first transmission rack 154. The first transmission rack 154 is provided on the first push rod 151 along the first direction x, the first transmission gear 153 is meshedly connected to the first transmission rack 154, the first driving member 152 is mounted on the first housing 111 or the second housing 112, and the output end of the first driving member 152 is connected to the first transmission gear 153. The first driving member 152 drives the first transmission gear 153 to rotate, thereby driving the first transmission rack 154 and the first push rod 151 to move along the first direction x, thereby pushing the cylindrical sheet to move along the first direction x.

[0083] Optionally, considering that the cylinder pieces are arranged within the first shell 111 and the second shell 112 along the second direction y, the cylinder pieces need to remain stable within the installation cavity. Therefore, when the first pushing mechanism 15 is disposed within the installation cavity, the first shell 111 and the second shell 112 need to be provided with a positioning structure to limit the cylinder pieces and prevent the cylinder pieces from shaking or shifting in the first direction x. To this end, the first pushing mechanism 15 is located outside the first shell 111 and the second shell 112. The first shell 111 and the second shell 112 are provided with a second opening communicating with the installation cavity. The second opening is located on a side of the first shell 111 and the second shell 112 away from the first opening 1110. The first push rod 151 is movably disposed through the second opening. This not only helps to stabilize the cylinder pieces within the installation cavity, but also simplifies the structure of the first shell 111 and the second shell 112 and helps to reduce the volume of the first shell 111 and the second shell 112.

[0084] Optionally, as can be seen from the above, the first fixed baffle 113 and the second fixed baffle 114 are provided with a first positioning portion 1131. Based on this, the first push rod 151 is provided with a second positioning portion 1213, so as to facilitate cooperation with the first positioning portion 1131 when the first push rod 151 pushes the cylinder to move along the first direction x, so as to facilitate guiding and avoiding the movement of the first push rod 151.

[0085] As an alternative embodiment, the first pushing mechanism 15 may also be an electric push rod, a hydraulic push rod, or a scissor-type telescopic bracket.

[0086] In some embodiments, the second pushing mechanism 16 includes a driving assembly 161, a first moving rod 162, a second moving rod 163, a first push plate 164 and a second push plate 165. The first moving rod 162 and the second moving rod 163 are respectively arranged on both sides of the driving assembly 161 along the second direction y, one end of the first moving rod 162 and the second moving rod 163 is connected to the driving assembly 161, the other end of the first moving rod 162 is connected to the first push plate 164, and the other end of the second moving rod 163 is connected to the second push plate 165. The first push plate 164 is located on the side of the first barrel group 12 away from the second barrel group 13, and the second push plate 165 is located on the side of the second barrel group 13 away from the first barrel group 12. The driving assembly 161 is used to drive the first moving rod 162 and the second moving rod 163 to move in a direction close to each other, so as to drive the first push plate 164 and the second push plate 165 to push the barrel sheet.

[0087] In this way, the first push plate 164 and the second push plate 165 are driven simultaneously by a driving member to move, so as to push the barrel sheets of the first barrel group 12 and the barrel sheets of the second barrel group 13 at the same time, which is beneficial to reduce energy consumption and improve the assembly efficiency of the casing.

[0088] Optionally, the drive assembly 161 includes a second drive member 1611, a second transmission gear 1612, a second transmission rack 1613, and a third transmission rack 1614. The second drive member 1611 is fixedly mounted on the housing 11. The output end of the second drive member 1611 is connected to the second transmission gear 1612. The second transmission rack 1613 and the third transmission rack 1614 are respectively meshed and connected to the second transmission gear 1612. The end of the second transmission rack 1613 away from the second transmission gear 1612 is connected to the first moving rod 162, and the end of the third transmission rack 1614 away from the second transmission gear 1612 is connected to the second moving rod 163. This can improve the smoothness of the movement of the cylindrical sheet along the second direction y.

[0089] Optionally, the drive assembly 161 is installed on the outside of the housing 11, the first shell 111 is provided with a first push groove 1112 and a first push hole 1113 communicating with the installation cavity, the first push groove 1112 is provided at the top of the first shell 111, the second shell 112 is provided with a second push groove 1122 and a second push hole 1123 communicating with the installation cavity, the second push groove 1122 is provided at the top of the second shell 112, the first push groove 1112, the second push groove 1122, the first push hole 1113 and the second push hole 1123 are arranged along the second direction. Extending toward y, the first transmission rack 154 is movably mounted on the first pushing groove 1112 and is located outside the first shell 111, the second transmission rack 1613 is movably mounted on the second pushing groove 1122 and is located outside the second shell 112, the first moving rod 162 is movably mounted on the first pushing hole 1113 and extends into the mounting cavity of the first shell 111 to be connected with the first push plate 164, and the second moving rod 163 is movably mounted on the second pushing hole 1123 and extends into the mounting cavity of the second shell 112 to be connected with the second push plate 165.

[0090] In this way, the drive assembly 161 is located outside the outer shell 11, which can reduce the components in the installation cavity, so that when the second pushing mechanism 16 pushes the cylinder to move along the second direction y, there are no other components on the moving path of the cylinder, which is conducive to the movement of the cylinder along the second direction y, and improves the reliability of the movement of the cylinder along the second direction y. At the same time, it can also simplify the structure of the first shell 111 and the second shell 112, and improve the stability of the cylinder in the first shell 111 and the second shell 112.

[0091] As an alternative embodiment, the second pushing mechanism 16 may also be an electric push rod, a hydraulic push rod, or a scissor-type telescopic bracket, etc. The second pushing mechanism 16 may be installed in the installation cavity.

[0092] In some embodiments, the housing 11 also includes a fixed bracket 115, the fixed bracket 115 is provided with a slide rail extending along the second direction y, the first shell 111 and the second shell 112 are respectively provided with a slider 1114, the slider 1114 is slidably connected to the slide rail, the opening and closing mechanism 14 is respectively connected to the first shell 111 and the second shell 112, and the opening and closing mechanism 14 is used to drive the first shell 111 and the second shell 112 to move along the second direction y so that the slider 1114 moves along the slide rail.

[0093] In this way, the cooperation between the slider 1114 and the slide rail is conducive to improving the movement stability of the first shell 111 and the second shell 112, thereby improving the operational reliability of the submarine cable armor casing device 1.

[0094] It is understandable that in other embodiments, the slide rails may also be disposed on the first housing 111 and the second housing 112 , and the slider 1114 may be disposed on the fixing bracket 115 .

[0095] Optionally, the fixed bracket 115 includes a first frame 1151, a second frame 1152 and a third frame 1153. The third frame 1153 is located between the first shell 111 and the second shell 112 along the second direction y and extends along the first direction x. The third frame 1153 is located above the first shell 111 and the second shell 112. The second driving member 1611 is installed on the third frame 1153. One end of the third frame 1153 is connected to the first frame 1151, and the other end of the third frame 1153 is connected to the second frame 1152. The first frame 1151 and the second frame 1152 are respectively provided with a slide rail extending along the second direction y, and the first shell 111 and the second shell 112 are respectively provided with a slider 1114 at both ends of the first direction x. The first frame 1151 is slidably connected to one end of the first shell 111 and the second shell 112 through the slide rail, and the second frame 1152 is slidably connected to the other end of the first shell 111 and the second shell 112 through the slide rail. This is beneficial to improving the structural reliability of the shell 11 and avoiding occupying the space between the first shell 111 and the second shell 112, which is beneficial to matching the size of the cylinder with the size of the submarine cable and improving the protective effect of the casing on the submarine cable.

[0096] Optionally, the opening and closing mechanism 14 includes a third driving member 141, a third transmission gear, a fourth transmission rack 142 and a fifth transmission rack 143. The third driving member 141 is fixedly mounted on the third frame 1153, the output end of the third driving member 141 is connected to the third transmission gear, one end of the fourth transmission rack 142 is fixedly connected to the first shell 111, and the other end of the fourth transmission rack 142 is meshed with the third transmission gear, one end of the fifth transmission rack 143 is fixedly connected to the second shell 112, and the other end of the fifth transmission rack 143 is meshed with the third transmission gear.

[0097] In this way, the third driving member 141 is started to drive the third transmission rack 1614 to rotate, so as to drive the fourth transmission rack 142 and the fifth transmission rack 143 to move relative to each other, thereby driving the first shell 111 and the second shell 112 to move closer to or away from each other, so as to close or open the outer shell 11, so that the cylinder sheet of the first cylinder group 12 is in contact with or separated from the cylinder sheet of the second cylinder group 13.

[0098] Optionally, a first avoidance groove 1115 is provided at the top of the first shell 111, and a second avoidance groove 1124 is provided at the top of the second shell 112. The first avoidance groove 1115 is provided corresponding to the fifth transmission rack 143 and is used to avoid the fifth transmission rack 143 when the first shell 111 and the second shell 112 are brought together or the outer shell 11 is closed. The second avoidance groove 1124 is provided corresponding to the fourth transmission rack 142 and is used to avoid the fourth transmission rack 142 when the first shell 111 and the second shell 112 are brought together or the outer shell 11 is closed. This can improve structural reliability, help reduce the gap between the first shell 111 and the second shell 112 when the outer shell 11 is closed, and facilitate the connection of the barrel sheets of the first barrel group 12 and the second barrel group 13.

[0099] As an alternative embodiment, the opening and closing mechanism 14 may also be a pulley transmission structure or a hydraulic pushing mechanism.

[0100] For ease of reading and understanding, the following example illustrates the working process of the submarine cable armor casing device 1:

[0101] (1) Before the submarine cable armor casing device 1 is placed under water, the outer shell 11 of the submarine cable armor casing device 1 is opened so that the first shell 111 and the second shell 112 are spaced apart. The submarine cable armor casing device 1 is lowered to the submarine cable by a diving robot or an operating vessel. The submarine cable enters between the first fixed baffle 113 and the second fixed baffle 114 through the gap between the first shell 111 and the second shell 112. The first shell 111 and the second shell 112 are driven to move toward each other by the opening and closing mechanism 14 so that the first shell 111 abuts against the second shell 112. At this time, the outer shell 11 is closed, and the first barrel 121 is spaced apart from the third direction z along the first direction x.

[0102] (2) The first driving member 152 of the first pushing mechanism 15 drives the first push rod 151 to move along the first direction x, so as to push the first cylinder piece 121 to move in the direction close to the third cylinder piece 131, so that the first matching portion 123 is matched with the second matching portion 133 (that is, the protruding structure enters the groove structure). At this time, the first cylinder piece 121 and the third cylinder piece 131 are locked along the second direction y.

[0103] (3) The first cylinder 121 and the third cylinder 131 are respectively pushed out of the first shell 111 and the second shell 112 from the first opening 1110 by the two first pushing mechanisms 15. At this time, the cylinder formed by the connection between the first cylinder 121 and the third cylinder 131 maintains central stability under the support of the first fixed block 113 and the second fixed block 114. There is a gap between the second cylinder 122 and the first fixed block 113 along the second direction y, and there is a gap between the fourth cylinder 132 and the second fixed block 114 along the second direction y. The second driving member 1611 of the second pushing mechanism 16 drives the first push plate 164 and the second push plate 165 to move simultaneously along the second direction y to push the second cylinder 122 to move. The fourth cylinder piece 132 moves to fit the first fixed block piece 113, and the fourth cylinder piece 132 moves to fit the second fixed block piece 114. Subsequently, the fourth cylinder piece 132 is pushed along the first direction x by the first pushing mechanism 15, so that the first tenon 1221 of the fourth cylinder piece 132 is mortise and tenon connected with the first tenon groove 1211 of the third cylinder piece 131, and the fourth cylinder piece 132 and the third cylinder piece 131 are snap-connected through the first clamping portion 1212 and the second clamping portion 1222. At this time, the third cylinder piece 131 and the fourth cylinder piece 132 are spliced ​​along the first direction x. Then the second cylinder piece 122 is pushed along the first direction x by the first pushing mechanism 15, so that the first tenon 1221 of the second cylinder piece 122 is mortise and tenon connected with the first tenon groove 1211 of the first cylinder piece 121, and the second cylinder and the first cylinder piece 121 are snap-connected through the first clamping portion 1212 and the second clamping portion 1222. At this time, the first cylinder piece 121 and the second cylinder piece 122 are spliced ​​along the first direction x. At the same time, in the process of the first pushing mechanism 15 pushing the second cylinder piece 122 along the first direction x, the second cylinder piece 122 and the fourth cylinder piece 132 are matched and connected through the first matching portion 123 and the second matching portion 133, so that the second cylinder piece 122 and the fourth cylinder piece 132 are locked along the second direction y, so that the first cylinder piece 121, the second cylinder piece 122, the third cylinder piece 131 and the fourth cylinder piece 132 are connected to enclose a solid columnar protective tube.

[0104] Repeat the above step (3) to continue extending the casing length according to the actual casing length requirement.

[0105] When the casing is fully extended, the housing 11 can be removed from the water. First, the first pushing mechanism 15 completely pushes the sleeve out of the first shell 111 and the second shell 112. Then, the opening and closing mechanism 14 drives the first shell 111 and the second shell 112 away from each other to open the housing 11. The housing 11 is then moved upward by a submersible robot or workboat, allowing the submarine cable to escape from the housing 11 through the gap between the first shell 111 and the second shell 112. The housing 11 continues to move until it is removed from the water.

[0106] It can be seen that the submarine cable casing device according to the embodiment of the present application has at least the following advantages:

[0107] 1) The sleeves of the first sleeve group 12 and the second sleeve group 13 are slidably connected along the first direction x by the protrusion structure and the groove structure, and can be aligned and assembled without the aid of tools, thereby ensuring a stable connection of the sleeves along the second direction y. At the same time, it has the characteristics of simple structure and convenient installation, which can reduce the accessories and tools required for the installation of the sleeve, thereby improving installation efficiency and ease of operation.

[0108] 2) The splicing of the tube segments along the first direction x combines the two connection methods of mortise and tenon and snap fasteners to achieve double interlocking, thereby providing a stable mechanical connection for the casing, improving the reliability of the tube segment splicing, and effectively preventing loosening or falling off, so that the casing can serve for a long time in the deep-sea high-pressure environment and ensure that the casing will not loosen due to water flow or vibration.

[0109] 3) The tube segments are sequentially arranged and stored in the housing 11 along the second direction y. The tube segments are pushed by the first pushing mechanism 15 and the second pushing mechanism 16 to realize automatic segmented pushing and installation of modular tube segments, thereby meeting the requirements of casing extension installation and improving construction efficiency.

[0110] 4) The submarine cable armor casing device 1 integrates modular splicing design and automatic sliding connection method. The overall assembly method is simple and the degree of automation is high. It can reduce the dependence of the operation on professional level and has strong adaptability.

[0111] 5) By providing a detachable connection between the sleeve and the liner, the diameter of the casing can be adjusted according to demand to adapt to submarine cables of different diameters, thereby improving the versatility of the submarine cable armor casing device 1.

[0112] 6) The submarine cable armor casing device 1 can be docked with a submersible robot (or an operating vessel) to achieve remote automatic deployment, which is beneficial to reducing labor costs and safety risks and improving operation safety and efficiency.
