Description

High-flexibility floating cable for remote transfer offshore robot

Technical Field

The utility model relates to a cable field, in particular to high flexibility floating cable for remote transmission offshore robot.

Background

The floating cable is a cable capable of floating on the water surface, and is a cable for realizing important functions of transmitting power, signals and the like between water surface or underwater equipment and other working parts.

The offshore robot can work on the sea and can finish the work of detecting, cleaning up marine garbage and the like.

Generally, in the working process of the offshore robot, a floating cable is needed to transmit power, signals and the like, so that the floating cable can be continuously dragged, twisted and the like in the working process of the robot, bears high tensile force and rotating force, and is easily damaged.

Disclosure of Invention

In order to solve the technical problem, the utility model discloses a remote transmission offshore robot uses high flexible floating cable, the technical scheme of the utility model is implemented like this:

the utility model provides a high flexibility floating cable for remote transfer offshore robot, includes cable core and crowded package in the oversheath in the cable core outside, the cable core includes two heart yearns one and one heart yearn two, two heart yearns one and one the mutual transposition of heart yearn two, heart yearn one include first conductor and crowded package in the first insulation layer in the first conductor outside, heart yearn two include the sinle silk and crowded package in the polyester band layer in the sinle silk outside, the sinle silk includes two wires of transposition each other, the wire include the second conductor and crowded package in the second insulation layer in the second conductor outside, the oversheath with fill in the space between the cable core has the filler.

Preferably, the first core wire has a size of 20 AWG.
