[0021] The embodiments of the present utility model disclose a special cable for an underwater robot.

[0022] According to the appendix Figures 1-5As shown in the figure, it includes an underwater special inner cable 1. An outer fixed protection support sleeve 2 is arranged outside the underwater special inner cable 1. The fixed protection support sleeve 2 includes a front support sleeve 21 and a rear protection sleeve 22. The front support sleeve 21 includes a fixing ring 211, support columns 213 and an intermediate ring 216. The rear protection sleeve 22 includes steel cables 222 and a bottom ring 223. One end of the support column 213 is fixedly connected to the bottom of the fixing ring 211, and the other end of the support column 213 is fixedly connected to the top of the intermediate ring 216. One end of the steel cable 222 is fixedly connected to the top of the intermediate ring 216, and one end of the steel cable 222 is fixedly connected to the bottom of the bottom ring 223. The bottom ring 223 is snap-fitted inside the fixing ring 211. When using the underwater special inner cable 1, first connect multiple groups of fixed protection support sleeves 2 in series outside the underwater special inner cable 1. After the underwater special inner cable 1 is integrally fixed, then put the device into the water for use. The front support sleeve 21 of the fixed protection support sleeve 2 provides support and fixation for the underwater special inner cable 1, while the rear protection sleeve 22 enables the underwater special inner cable 1 to be bent. Multiple groups of fixed protection support sleeves 2 cooperate with each other to realize the protection, heat dissipation and support of the underwater special inner cable 1.

[0023] The underwater special inner cable 1 includes a cable core 11, an insulating protection inner layer 12 and a waterproof protection outer layer 13. The cable core 11 is arranged inside the insulating protection inner layer 12, and the insulating protection inner layer 12 is arranged inside the waterproof protection outer layer 13. The waterproof and insulation of the underwater special inner cable 1 are protected by its own protective layer. The underwater special inner cable 1 is divided into various functional cables, including power supply cables, communication cables and control cables, etc. These cables are fixedly connected inside the fixed protection support sleeve 2.

[0024] The front support sleeve 21 further includes fixing pieces 214 and rigid inner ropes 215. The fixing pieces 214 are slidably connected to the rigid inner ropes 215. The rigid inner ropes 215 are fixedly connected between the fixing ring 211 and the intermediate ring 216. The underwater special inner cable 1 is movably snap-fitted on the fixing pieces 214. The fixing pieces 214 are used to separate three groups of cables inside the front support sleeve 21 to prevent damage caused by mutual collision and play a role of fixed support. The rigid inner ropes 215, on the one hand, play a role in fixing the fixing pieces 214, and on the other hand, can still connect the fixing ring 211 and the intermediate ring 216 after the support columns 213 are damaged by impact.

[0025] An annular iron net 212 is arranged inside the front support sleeve 21, and a protective soft net 221 is arranged inside the rear protection sleeve 22. The purposes of the annular iron net 212 and the protective soft net 221 are to prevent some fish or hard stones from colliding with and biting the cable to cause damage, so as to improve the protection performance.

[0026] A rotating clamp 2111 is rotatably connected to the top end of the fixed ring 211. A clamping groove 2112 is formed in the rotating clamp 2111. A fixing bolt 2113 is arranged in the rotating clamp 2111. The rotating clamp 2111 is fixedly connected to the fixed ring 211 through the fixing bolt 2113. The rotating clamp 2111 fixedly connects the next set of fixed protection support sleeves 2 to the inside of the fixed ring 211 by means of a groove connection.

[0027] A clamping block 2231 is fixedly connected to the outer surface of the bottom ring 223. The clamping block 2231 is movably clamped in the rotating clamp 2111. During use, the fixed ring 211 of the previous set of fixed protection support sleeves 2 is movably clamped outside the bottom ring 223, and the two sets of fixed protection support sleeves 2 are fixed by the fixing bolt 2113, making the assembly and disassembly simpler.
