Description

Technical Field

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

[0002] Submarine cables are cables wrapped with insulating materials and laid on the seabed for telecommunication transmission. Submarine cables are divided into submarine communication cables and submarine power cables; submarine communication cables are mainly used for communication services, which are expensive but have a high degree of confidentiality; submarine power cables are mainly used for underwater transmission of high-power electric energy, which is equivalent to the function of underground power cables, except for the application scenarios and laying methods.

[0003] After the submarine cable is put into use in the submarine pipeline erection, since the outer peripheral insulating layer is completely exposed, the rubber insulating layer is prone to damage by rats during the ebb period of the submarine pipeline and corrosion and aging damage by seawater, resulting in the exposure of the internal core and causing cable failures. When detecting and repairing the cable in the submarine pipeline, the outer periphery of the cable is not cleaned, resulting in impurities adhering to the outer periphery of the cable greatly affecting the detection and subsequent repair, causing errors in detection and unstable repair. The adhering impurities affect the fitting. In addition, when using a heat shrinkable tube to repair the outer periphery of the cable, only one side can be heated, and the heat shrinkable tube cannot be heated evenly, resulting in an unstable connection between the repaired heat shrinkable tube and the outer periphery of the cable, and it is still extremely easy to fall off.

[0046] On the detection ring 50, detection rods 58 are fixedly installed in the detection holes 51 by bolts. At the center of the detection holes 51 on the detection rods 58, a detection bottom ring 55 is installed. The top of the T-shaped movable rod 56 movably penetrates through the detection bottom ring 55. Both the detection bottom ring 55 and the electric telescopic rod 34 are connected to the PLC controller 57 through wires. The detection roller 54 fixedly installed at the center of the bottom of the detection frame 53 is movably abutted against the outer periphery of the submarine pipeline cable body 90. The detection roller 54 is used to detect the concave part of the submarine pipeline cable body 90 under the action of the detection return spring 52.

[0047] Refer to Figure 3 and Figure 11 At both ends of the inner wall of the repair ring 40, L-shaped connecting rods 43 are fixedly installed by bolts. 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 tooth block 41 is fixedly installed on the outer periphery of the repair ring 40. The repair frame 42 is movably connected to the repair ring 40 through the rotating tooth block 41. At the bottom of one side of the repair frame 42, a repair plate 44 is fixedly installed by bolts. At the center of the bottom of one side of the repair plate 44, a hot air blower 45 for heating the heat shrinkable tube body 31 is fixedly installed to rotate and heat the outer periphery of the heat shrinkable tube body 31, so that the heat shrinkable tube body 31 completely and evenly fits with the outer periphery of the submarine pipeline cable body 90, achieving a stable repair effect.

[0048] At the center of one side of the top of the repair frame 42, a driving motor 46 is fixedly installed by bolts. The output end of the driving motor 46 is connected to a driving gear 47 located in the repair frame 42, and the driving gear 47 is meshed with the rotating tooth block 41. There are three groups of support rings 30, 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 with both sides of the T-shaped positioning plates 48 are fixedly installed on both sides of the inside of the repair frame 42. Through connection, the cleaning, detection, and repair of the submarine pipeline cable body 90 are realized.

[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 wheel 62 in the fixing groove 61 rotate stably during the forward movement. The friction shaft 72 in 2 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 meshing of the first bevel gear 76. During the rotation process, the rotating shaft 71 drives the top driving gear 26 to mesh 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 clean 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 concave portion 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 detection bottom ring 55 is subjected to force to send 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 concave portion 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, and 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 plates 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 on 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 the effect of multiple detection and repair of the submarine pipeline cable body 90 can be achieved;

[0052] When the heat-shrinkable tube body 31 covers the depression of the submarine pipeline cable body 90 and enters the repair ring 40, the drive motor 46 on the repair ring 40 starts to drive the repair frame 42 to rotate on the outer periphery of the repair ring 40. The drive gear 47 on the repair frame 42 meshes with the rotating tooth block 41 on the repair ring 40, so that the repair frame 42 rotates stably on the outer 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-shrinkable tube body 31. The heating is uniform and stable, so that the heat-shrinkable tube body 31 is completely, uniformly and stably attached to the outer periphery of the submarine pipeline cable body 90.

[0053] The embodiments of the present invention have been described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge of those skilled in the art without departing from the purpose of the present invention.
