Description

Flexible hoisting traction device for submarine cable

Technical Field

The utility model relates to the technical field of submarine cable hoisting, in particular to a flexible hoisting traction device for submarine cables.

Background

Submarine cables (submarine cables) are cables wrapped with insulating materials and laid on the sea floor for telecommunication transmission. Submarine cables are classified into submarine communication cables and submarine power cables. Now 99% of the internet data transmission is transmitted via submarine cables. In the manufacture of submarine cables, the optical fibers are first embedded in a jelly-like compound, without damaging the cable even in the case of contact with sea water. The cable is then encased in a steel tube to prevent the pressure of the water from damaging it. Then wrapping the steel wire with extremely high overall strength, sleeving the steel wire in a copper pipe, and finally sleeving a protective layer made of polyethylene material. The laying of submarine cables near the coast of the continental shelf usually uses light cables with stronger steel wires and is covered with an asphalt coating to prevent seawater corrosion.

The submarine cable is high in technological content due to the fact that the submarine cable contains transmission channels such as light, electricity and signals, meanwhile, in order to protect electronic elements such as internal optics and the like, the cable is generally coated with a plurality of layers of isolating layers, reinforcing layers, fireproof layers and waterproof layers, and finally, the submarine cable is coated with a rubber layer, so that the submarine cable is not easy to bend and tie, and metal fittings are not suitable to be used for hoisting and traction.

However, the submarine cable is inevitably required to be hoisted and pulled when being laid. The prior art generally uses metal type buckle fittings, and has the technical defects of heavy weight, easy damage to cables and inconvenient use.
