[0038] The utility model is described in detail below with reference to the accompanying drawings.

[0039] like Figure 1-6 As shown, an underwater floating communication cable includes a core group 2 and an isolation sleeve 1 covering the core group 2, the core group 2 includes a protective sleeve 21 and a plurality of copper cores 22 arranged in the protective sleeve 21, the isolation sleeve 1 is nested in the protective sleeve 21, an outer isolation layer 13 is arranged between the isolation sleeve 1 and the protective sleeve 21, a wear-resistant hard rubber sleeve 11 is nested on the outer wall of the isolation sleeve 1, and an anti-corrosion layer 12 is coated on the surface of the wear-resistant hard rubber sleeve 11; with the cooperation of the wear-resistant hard rubber sleeve 11 and the protective sleeve 21, the copper core 22 is doubly protected to achieve the effect of waterproofing, wear resistance and corrosion resistance, and the oxidation reaction is not easy to enter the copper core 22 after long-term use, thereby improving its service life.

[0040] The outer isolation layer 13 includes an aluminum oxide mesh 14, the aluminum oxide mesh 14 is wrapped with a heat-resistant layer 15 on the outside, the heat-resistant layer 15 is wrapped with a wear-resistant mesh sleeve 16 on the outside, the wear-resistant mesh sleeve 16 is wrapped with an anti-corrosion coating 17 on the outside, and the outer surface of the anti-corrosion coating 17 is provided with a plurality of wear-resistant particles 18. The anti-corrosion layer is made of glass fiber material and has good anti-corrosion performance; the wear-resistant mesh sleeve 16 is made of copper wire material and has good wear resistance; the wear-resistant particles 18 are silicon carbide particles and have good wear-resistant protection. The heat-resistant layer 15 can improve the high temperature resistance of the wire, the wear-resistant mesh sleeve 16 and the wear-resistant particles 18 can improve the wear resistance of the wire surface, and greatly improve the service life of the anti-corrosion layer and the anti-corrosion coating 17.

[0041] The copper wire core 22 is nested with an insulating sleeve 23, and an inner isolation layer 24 surrounding the insulating sleeve 23 is arranged in the protective sleeve 21. The inner isolation layer 24 includes a filler 25 and a composite shielding layer 26. The composite shielding layer 26 is nested in the insulating sleeve 23; the filler 25 is filled into the protective sleeve 21. The composite shielding layer 26 is composed of nano-silica sol, iron, conductive filler, magnesium powder, titanium oxide, silicon carbide and graphene, which effectively eliminates the magnetic field inside the protective sleeve 21 and improves the anti-interference ability of the cable.

[0042] The fillers 25 are arranged in the gaps between the copper wire cores 22. There are certain gaps between the fillers 25, and the protective gas will fill the gaps to protect the cables.

[0043] The wear-resistant hard rubber sleeve 11 is nested with a plurality of floating structures 3 along the length direction. The floating structure 3 includes a guide sleeve 31 nested in the outer ring wall of the wear-resistant hard rubber sleeve 11. The outer ring wall of the guide sleeve 31 is formed with an annular groove 32. The annular groove 32 is installed with a floating block 33. The floating block 33 has a built-in sealing cavity 34. The sealing cavity 34 is provided with a sealing cover 35. The floating block 33 is formed with a connecting block 36. The connecting block 36 can be embedded in the annular groove 32 and slide along the annular groove 32 to adjust the position. The floating block 33 can be installed in the annular groove 32 of the guide sleeve 31 through the connecting block 36. The sealing cavity 34 formed by the floating block 33 makes the floating block 33 have buoyancy underwater, which can drive the wires and cables to float up and will not sink underwater. In addition, according to the weight of the wires and cables, a corresponding number of floating blocks 33 can be installed in the annular groove 32 to adjust the buoyancy. The sinking depth of the wires and cables can be adjusted accordingly, and the practicality is further improved; when the cable needs to be maintained, it is not necessary to salvage it in deeper water.

[0044] Specifically, since the floating block 33 has a sealed cavity 34 built therein, and the sealed cavity 34 is provided with a sealed cover 35, a counterweight block can be placed in the sealed cavity 34 through the sealed cover 35 to further adjust the buoyancy of the floating block 33, so that the sinking depth of the wires and cables can be further fine-tuned.

[0045] Furthermore, the connecting block 36 is formed with a driving cavity 39 of a hollow structure along the length direction, and stop blocks 46 that contact and cooperate with the groove wall of the annular groove 32 are slidably installed at both ends of the driving cavity 39; when the floating block 33 is embedded in the annular groove 32 of the guide sleeve 31 through the connecting block 36, the stop block 46 can move outward along the driving cavity 39, so that the stop block 46 contacts the end wall of the annular groove 32, so that the floating block 33 can be locked and connected with the annular groove 32 through the connecting block 36, thereby preventing the floating block 33 from moving.

[0046] Furthermore, the connecting block 36 is provided with a driving mechanism 4 for driving the stop block 46 to move along the length direction of the driving cavity 39. The driving mechanism 4 includes an adjusting rod 41 arranged perpendicular to the driving cavity 39. A driving slider 45 is installed at the bottom of the adjusting rod 41. The driving slider 45 moves radially to drive the stop block 46 to slide laterally. When the floating block 33 is embedded in the annular groove 32 of the guide sleeve 31 through the connecting block 36, the rotating adjusting rod 41 is continuously inserted into the driving cavity 39, and the driving slider 45 is driven by the adjusting rod 41 to move along the length direction of the adjusting rod 41, and then the stop block 46 is driven to move outward along the driving cavity 39 until it contacts the end wall of the annular groove 32, thereby realizing friction locking.

[0047] Furthermore, the contact surface of the stop block 46 and the driving slider 45 is formed with an inclined first bevel 47, and the driving slider 45 is formed with a second bevel 48 parallel to the first bevel 47; when the adjusting rod 41 is rotated and continuously inserted into the driving cavity 39, and the driving slider 45 is driven by the adjusting rod 41 to move along the length direction of the adjusting rod 41, the second bevel 48 of the driving slider 45 will slide and cooperate with the first bevel 47 of the stop block 46, driving the stop block 46 to move outward along the driving cavity 39.

[0048] Preferably, the connecting block 36 is radially provided with a sliding hole 42 connected to the driving cavity 39 along the guide sleeve 31, and the sliding hole 42 is installed with a threaded sleeve 43 threadedly matched with the adjusting rod 41, and the top of the driving slider 45 is installed with a bearing seat 44 movably connected to the end of the adjusting rod 41; when the adjusting rod 41 is rotated, the adjusting rod 41 is threadedly matched with the threaded sleeve 43 of the sliding hole 42, so that the adjusting rod 41 can be lifted and lowered, and is movably connected with the driving slider 45 through the bearing seat 44. When the adjusting rod 41 is rotated, the driving slider 45 will not rotate, thereby ensuring the lifting and lowering movement of the driving slider 45.

[0049] Preferably, the driving cavity 39 is equipped with a guide block 49, and the guide block 49 is formed with a guide surface for the driving slider 45 to slide radially. The guide block 49 is equipped with a tension spring 50, and the outer end of the tension spring 50 is connected to the stop block 46; the guide surface allows the driving slider 45 to slide radially without lateral movement. In addition, when the adjustment rod 41 moves outward and the position of the floating block 33 needs to be adjusted, the driving slider 45 will move with the movement of the adjustment rod 41. At this time, the stop block 46 will retreat into the driving cavity 39 under the elastic drive of the tension spring 50, so that the overall length of the connecting block 36 becomes smaller, and the floating block 33 can be disassembled or moved to other positions of the annular groove 32.

[0050] Furthermore, the annular groove 32 includes a top groove 37 whose width matches the length of the connecting block 36 and a bottom groove 38 that is larger than the top groove 37. The top groove 37 is connected to the bottom groove 38. The stop block 46 can move outward along the driving cavity 39 and contact the end wall of the bottom groove 38. At this time, the length of the connecting block 36 is greater than the width of the top groove 37, and the connecting block 36 will not fall off from the annular groove 32, thereby maintaining the stability of the connection.

[0051] In summary, it can be seen that the utility model has the above-mentioned excellent characteristics, which can enhance the performance unprecedented in the prior art and become a product with great practical value.

[0052] The above contents are only preferred embodiments of the present invention.
