Self-luminous high-strength water-tight cable

By coating the outer layer of the watertight cable with a luminescent coating and combining it with a multi-layer structure design, the problem of cable maintenance difficulties caused by the dim underwater environment is solved. This achieves self-luminous positioning and high tensile strength, improving the safety and maintenance efficiency of underwater equipment.

AI Technical Summary

Technical Problem

The dark underwater environment makes it difficult to quickly and accurately identify the cable route, connection nodes and damage locations during the operation and maintenance of watertight cables, increasing the risk of misoperation and operation and maintenance costs.

Method used

Design a self-luminescent high-strength watertight cable. By coating the outer layer of the cable with a luminescent coating and combining it with a multi-layer structure to enhance the cable's tensile strength and sealing performance, including a cable core, a water-blocking layer, an encapsulation layer, a Kevlar tensile layer, and a sheath, a high-power and low-power core stranding design and an energy-storing luminescent coating are adopted.

Benefits of technology

It enables cables to emit light autonomously in dim underwater environments, facilitating rapid positioning, reducing the risk of misoperation, improving operation and maintenance efficiency, and enhancing the tensile strength and sealing performance of cables. It is suitable for complex underwater environments such as lakes and nearshore engineering projects.

Abstract

The utility model relates to cable technical field, concretely relates to a self-luminous high-strength water-tight cable, including setting in the cable core and water-blocking layer, encapsulation layer, kevlar silk tensile layer, sheath and luminous coating that cover in cable core outside in proper order, the cable core is made by the symmetrical stranding of multiple high -power core line and multiple low -power core line center, and multiple low -power core line is filled in the gap between adjacent two high -power core line respectively, the encapsulation layer adopts the way of around package or longitudinal package and is wound outside water-blocking layer, and kevlar silk tensile layer adopts the way of weaving and is wound outside encapsulation layer, and the sheath is extruded and is formed outside kevlar silk tensile layer. Water-tight cable passes through the luminous coating of outer layer, and the cable can independently emit light in the dim environment under water, is convenient for the quick positioning cable trend, connection node and damaged position when the underwater equipment operation and maintenance, reduces the time cost of manual inspection or underwater robot operation, reduces the risk that the cable is damaged due to misoperation.
