Description

Technical Field

[0001] The present invention relates to the technical field of cable detection and repair, and in particular to an underwater unmanned platform dedicated to submarine pipeline cable detection and repair. Background Art

[0002] Submarine cables are cables wrapped with insulating materials, laid on the seabed and used for telecommunications transmission. Submarine cables are divided into submarine communication cables and submarine power cables. Submarine communication cables are mainly used for communication services. They are expensive but have a high degree of confidentiality. Submarine power cables are mainly used to transmit high-power electricity underwater. They have the same function as underground power cables, but their application scenarios and laying methods are different.

[0003] After the submarine cable is installed and put into use in the submarine pipeline, the outer insulation layer is completely exposed. The rubber insulation layer is easily damaged by rats gnawing during the water receding period of the submarine pipeline and corroded and aged by seawater, which exposes the internal core and causes cable failure. When inspecting and repairing the cables in the submarine pipeline, the outer periphery of the cable is not cleaned, resulting in impurities adhering to the outer periphery of the cable, which greatly affects the inspection and subsequent repair, causing errors in inspection and unstable repair. The adhered impurities affect the fit. In addition, when using heat shrink tubing to repair the outer periphery of the cable, it can only be heated on one side, and the heat shrink tubing cannot be heated evenly. This results in an unstable connection between the repaired heat shrink tubing and the cable periphery, and it is very easy to fall off. Summary of the Invention

[0043] An annular limiting groove 24 is provided on one side of the top of the annular limiting base 22, and an annular limiting block 25 is slidably connected to the annular limiting groove 24 on the annular limiting base 22.

[0045] See Figure 3 、 Figure 9 、 Figure 10 and Figure 12 The cam 35 is fixed to the top of the support ring 30 by bolts, and the cam 35 is fixed to the top of the support ring 30 by bolts.

A plurality of push plates 37 are evenly provided on the inner side of the two ends of the support ring 30 on one side of the heat shrinkable tube 31, and the limit ring 32 moves between the outer sides of the push plates 37. The outward movement of the electric telescopic rod 34 drives the heat shrinkable tube 31 between the limit rings 32 to expand and sleeve it onto the outer periphery of the submarine pipeline cable body 90. The push plate 37 is used to push the heat shrinkable tube 31 during the movement so that the heat shrinkable tube 31 falls off onto the outer periphery of the submarine pipeline cable body 90.

[0046] A detection rod 58 is fixedly installed in the detection hole 51 on the detection ring 50 by bolts, and a detection bottom ring 55 is installed on the detection rod 58 at the center of the detection hole 51. The top of the T-shaped movable rod 56 movably passes through the detection bottom ring 55. The detection bottom ring 55 and the electric telescopic rod 34 are connected to the PLC controller 57 through wires. The detection roller 54 fixed by bolts at the bottom center of the detection frame 53 is movably offset from the outer periphery of the submarine pipeline cable body 90. The detection roller 54 is used to detect the recessed part of the submarine pipeline cable body 90 under the action of the detection reset spring 52.

[0047] See Figure 3 and Figure 11L-shaped connecting rods 43 are fixedly installed at both ends of the inner wall of the repair ring 40 by bolts, and the other end of the L-shaped connecting rod 43 is fixedly installed on one side of the support ring 30 by bolts to support the repair ring 40. A rotating gear block 41 is fixedly installed on the outer periphery of the repair ring 40 by bolts. A repair frame 42 is movably connected to the repair ring 40 through the rotating gear block 41. A repair plate 44 is fixedly installed at the bottom of one side of the repair frame 42 by bolts. A hot air blower 45 for heating the heat shrinkable tube 31 is fixedly installed at the center of one side of the bottom of the repair plate 44 by bolts, and the outer periphery of the heat shrinkable tube 31 is rotated and heated, so that the heat shrinkable tube 31 is completely, thoroughly and evenly fitted with the outer periphery of the submarine pipeline cable body 90, achieving a stable repair effect.

[0048] A drive motor 46 is fixedly installed at the center of one side of the top of the repair frame 42 by bolts. The output end of the drive motor 46 is connected to the drive gear 47 located in the repair frame 42, and the drive gear 47 is meshed with the rotating gear block 41. The support rings 30 are in three groups, and the centers of the cleaning ring 21, the fixing ring 60, the support ring 30, the detection ring 50 and the repair ring 40 are all on the same axis. T-shaped positioning plates 48 are fixedly installed at the centers of both sides of the repair ring 40. Positioning rollers 49 that fit on both sides of the T-shaped positioning plates 48 are fixedly installed on both sides of the interior of the repair frame 42 by bolts, and are connected through to achieve cleaning, detection and repair of the submarine pipeline cable body 90.

[0049] Working principle: The submarine pipeline cable body 90 is passed through the center of the cleaning ring 21, the fixing ring 60, the support ring 30, the detection ring 50 and the repair ring 40 on the periphery of the submarine pipeline. The submarine pipeline cable body 90 is lifted out of the water surface of the submarine pipeline by the underwater drone 10. When the submarine pipeline cable body 90 is in the fixing ring 60, the gravity of the cable body itself and the elastic force of the limit spring 64 and the limit roller 66 toward the bottom make the friction roller in the fixed groove 61 rotate stably during the process of moving forward. The friction shaft 72 in the middle rotates the second pulley 75 on the fixed rod 74 synchronously through the first pulley 73 and the transmission belt 78. During the rotation process, the fixed rod 74 drives the second bevel gear 77 on the rotating shaft 71 to rotate through the engagement of the first bevel gear 76. During the rotation process, the rotating shaft 71 drives the top driving gear 26 to engage and drive the cleaning ring 21 on the annular limiting base 22 to rotate, so that the cleaning brush 23 inside the cleaning ring 21 rotates and cleans the outer periphery of the submarine pipeline cable body 90 to remove impurities.

[0050] After the impurities on the periphery of the submarine pipeline cable body 90 are cleaned, the submarine pipeline cable body 90 enters the detection roller 54 in the detection ring 50. Once it encounters a recessed area on the periphery of the submarine pipeline cable body 90, the detection roller 54 under the detection frame 53 descends under the action of the detection reset spring 52. At this time, the T-shaped movable rod 56 on the detection frame 53 penetrates and descends in the detection bottom ring 55, and the force on the detection bottom ring 55 sends a pulse signal to the PLC controller 57. At this time, the PLC controller 57 sends an extension work instruction to the electric telescopic rod 34 and the drive motor 46. When the detection roller 54 leaves the recessed area of ​​the submarine pipeline cable body 90, the pulse signal is reset to wait for the next detection.

[0051] During repair, the electric telescopic rods 34 at both ends of the top of the support ring 30 perform telescopic movement. During the extension, the limit rings 32 at both ends of the inner side are driven to move toward both ends through the support rods 36 and the support plate 35. After the limit rings 32 move to one side of the push plate 37, the push plate 37 is used to remove the compressed heat shrink tube 31 between the limit rings 32, so that the heat shrink tube 31 is sleeved onto the outer periphery of the submarine pipeline cable body 90, covering the concave part of the submarine pipeline cable body 90. The structure is simple and stable, and can achieve the effect of multiple inspection and repair of the submarine pipeline cable body 90.

[0052] When the heat shrink tube 31 covers the recessed part of the submarine pipeline cable body 90 and enters the repair ring 40, the driving motor 46 on the repair ring 40 starts to drive the repair frame 42 to rotate around the periphery of the repair ring 40. The driving gear 47 on the repair frame 42 movably engages the rotating gear block 41 on the repair ring 40, so that the repair frame 42 can rotate stably around the periphery of the repair ring 40 through the T-shaped positioning plate 48 and the positioning roller 49, driving the hot air blower 45 on the repair frame 42 to rotate and heat the heat shrink tube 31. The heating is uniform and stable, so that the heat shrink tube 31 can be thoroughly, evenly and stably fitted around the periphery of the submarine pipeline cable body 90.

[0053] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
