Undersea compression-resistant and stretch-resistant cable

Abstract

The invention discloses an undersea compression-resistant and stretch-resistant cable. The undersea compression-resistant and stretch-resistant cable comprises a waterproof sleeve; four arc-shaped grooves are formed in the inner wall of the waterproof sleeve in the circumferential direction; arc-shaped rods are arranged in the four arc-shaped grooves respectively; the two ends of the arc-shaped rods are fixedly connected with the inner walls of the corresponding arc-shaped grooves; each arc-shaped rod is sleeved with two sliding blocks; the two sliding blocks are both glidingly connected withthe corresponding arc-shaped rod; grooves are formed in the side walls of the two sliding blocks respectively; the inner walls of the grooves are rotationally connected with connecting rods; an insulating sleeve is arranged in the waterproof sleeve; four rubber rods corresponding to the positions of the arc-shaped grooves are arranged on the side wall of the insulating sleeve in the circumferential direction; one ends, far from the inner walls of the grooves, of the two connecting rods are both rotationally connected with one ends, far form the insulating sleeve, of the rubber rods; a placement groove is formed in the insulating sleeve; copper sheets are arranged in the placement groove; and four strands of cables are arranged in the insulating sleeve. The undersea compression-resistant and stretch-resistant cable is reasonable in design and simple in operation; and compression resistance requirements of the cable in the transverse direction and the longitudinal direction both can be satisfied, so that the undersea cable can resist any safety threatens caused by underwater subterranean flow.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a submarine compression and stretch resistance cable. Background technique [0002] Cables are usually made up of several wires or groups of wires. [0003] Definition 1: A wire made of one or more mutually insulated conductors and an outer insulating layer to transmit power or information from one place to another. [0004] Definition 2: A rope-like cable usually twisted by several or groups of wires (at least two in each group), each group of wires is insulated from each other, and is often twisted around a center, and the entire outer wrap Has a highly insulating covering. The cable has the characteristics of internal electrification and external insulation. [0005] Cables include power cables, control cables, compensation cables, shielded cables, high-temperature cables, computer cables, signal cables, coaxial cables, fire-resistant cables, marine cables, mining cables, al...

AI Technical Summary

Problems solved by technology

[0006] At present, most of the submarine cables use steel wire armored cables. The cables have relatively strong tensile resistance, but the compression resistance is not particularly good.
