The invention provides a multifunctional armored umbilical cable used for underwater equipment. The cable comprises an umbilical cable body and an armored layer wound out of the umbilical cable body,wherein the armored umbilical cable body comprises an outer layer insulation layer, optical fiber units, main electric wires, an inner layer insulation layer and a filler among the inner layer insulation layer and the main electric wires; a plurality of auxiliary electric wires and a middle filler are arranged in the inner layer insulation layer; an inner layer insulation layer filler is arrangedin gaps among the plurality of auxiliary electric wires and the inner wall of the inner layer insulation layer; a plurality of main electric wires are wrapped on the outer side of the inner layer insulation layer; a filler among the main electric wires and the inner layer insulation layer is arranged in gaps among the main electric wires and the outer wall of the inner layer insulation layer; theouter layer insulation layer is wrapped on the outer side of the plurality of main electric wires; and gaps among the plurality of main electric wires and the inner wall of the outer layer insulationlayer are provided with ground wires and optical fiber units. The armored umbilical cable has various functions of bearing, power supply, data transmission and the like, and can effectively meet requirements on providing power, real-time data transmission and the like for deep ocean survey and operation equipment.
Description
technical field [0001] The invention relates to a multifunctional armored umbilical cable for underwater equipment. Background technique [0002] With the development and utilization of land resources gradually barren, people have turned their attention to the vast ocean. The prerequisite for the development and utilization of marine resources is ocean exploration and seabed resource exploration. Underwater equipment is the key technical equipment for ocean exploration and seabed resource exploration. The armored umbilical cable is an important device connecting the underwater equipment and the surface mother ship. The armored umbilical cable not only needs to provide power and real-time data transmission for the underwater equipment, but also bears the impact of its own weight and the complex marine environment load during the operation of the underwater equipment, and also needs to withstand the underwater equipment during the release and recovery of the underwater equipme...
