Submarine cable laying device suitable for underwater remote control operation robot

Abstract

The invention discloses a submarine cable laying device suitable for an underwater remote control operation robot. The device is carried at the bottom of an underwater ROV, and accurate cable routingcontrol and recording can be realized by utilizing track control and recording functions of the ROV; the number of turns of rotation is fed back through a tensioning pulley servo motor, the laying length of the cable is accurately measured, calculated and recorded, the tensioning state of the released cable is kept through the servo motor torque for the tensioning pulley driving, and releasing andrecycling of the cable are achieved through cooperation of a cable arranging mechanism and the tensioning pulley. Attitude adjustment is carried out by combining attitude control of the ROV and an electric propulsion system of the cable laying device, and accurate plugging and unplugging of the submarine cable can be realized. The submarine cable laying device is mainly used for plugging connection and laying operation of photoelectric composite cables between main and secondary junction box nodes and between the junction box and a scientific instrument of a submarine scientific observation network, and can also be used for connection and laying of submarine cables and wires used by underwater production equipment and underwater factories.

Description

technical field [0001] The invention belongs to the field of underwater engineering equipment, and in particular relates to a submarine cable laying device suitable for an underwater remote-controlled operation robot. Background technique [0002] At present, there are mainly three platforms for ocean observation in the world: one is to use scientific research ships to conduct observations; the other is to use marine satellite remote sensing observations; the third is to establish a seabed scientific observation network for in-situ real-time observations. The submarine observation network is to place the observation instruments on the seabed or carry them on the underwater mobile observation platform, supply energy and collect information to each observation point through the wired network or mobile platform, so as to realize all-weather and all-weather monitoring of the ocean seabed underground, seabed ground, and sea water bodies. , Long-term, continuous automatic observat...

AI Technical Summary

Problems solved by technology

For the laying of optical cables between the junction boxes of the submarine scientific observation network, it is necessary to switch the operation path frequently. Due to the huge system composed of the mother ship and the furrowing plow, the laying path cannot be precisely controlled

[0006] 2. Since the mother ship needs to pull the furrowing plow forward through the wire cable, the furrowing plow cannot be too far away from the sea surface

Such requirements cannot be met by trenchers
