A permeable high-strength zero-buoyancy waterproof photoelectric composite umbilical cable

Abstract

The invention provides a penetration-type high-strength zero-buoyancy waterproof photoelectric composite umbilical cable. The penetration-type high-strength zero-buoyancy waterproof photoelectric composite umbilical cable comprises a buoyancy unit, a waterproof unit, a tension unit and a functional unit. The buoyancy unit comprises a modified high-molecular polyurethane permeable membrane and a glass bead filler, and a cavity between the polyurethane membrane and the tension unit is filled with glass beads. The waterproof unit comprises a waterproof sheath and a waterproof filler, and the tension unit is a tension protection net. The functional unit comprises an optical unit and an electric unit. When the photoelectric composite umbilical cable works, the gravity of an underwater section of the high-strength zero-buoyancy waterproof photoelectric composite umbilical cable is equal to the buoyancy borne by the underwater section of the high-strength zero-buoyancy waterproof photoelectric composite umbilical cable, i.e., achieving the zero buoyancy. Different buoyancy units are arranged to correspond to different types of umbilical cables, so that different types of cables can be selected according to zero buoyancy requirements. The cable has higher waterproof performances and tensile performances, and can be used for connection of underwater robots, large survey equipment and specific environment equipment in the field of military industry.

Description

technical field [0001] The invention relates to the technical field of umbilical cords, in particular to a permeable high-strength zero-buoyancy waterproof photoelectric composite umbilical cord with high tensile strength, zero buoyancy and waterproof, which is used in various deep-water submersibles, ships and towing equipment, as well as in the field of military industry . Background technique [0002] With the continuous improvement of underwater communication technology, the requirements for cables used in underwater towing, control, production and other systems are becoming more and more stringent. As a multifunctional transmission cable integrating power, digital signal, video signal and other functions, the umbilical cable can not only transmit the information collected by the towed device to the ship through optical fiber for analysis and processing, but also transmit the power to the towed device so that it can In addition to normal work, it is also the "nerve and ...

AI Technical Summary

Problems solved by technology

However, traditional umbilical cables have disadvantages such as poor resistance to deep-sea high pressure and easy loss of buoyancy under high pressure. Therefore, it is imminent to invent a zero-buoyancy umbilical cable with high strength and no loss of buoyancy.
