Method for eliminating submarine cable obstacles by submarine cable robot

Abstract

The invention discloses a method for eliminating submarine cable obstacles by a cabled underwater robot, and relates to the field of submarine cable operation and maintenance. At present, an underwater robot is only used for surveying submarine cables, measures are not taken for obstacles possibly causing the submarine cables, and the function is simple. The method comprises the following steps: when foreign matters threatening the safety of the submarine cable exist around the submarine cable, performing close-range detection and photographing on abnormal points by utilizing optical equipmentand/or acoustic equipment, and recording coordinates; using tools carried by the underwater robot with the cable and comprising a mechanical arm and a shearing device to remove small obstacles; and for a large obstacle, enabling the cable underwater robot to connect the obstacle to a rope released by an obstacle removing work ship through a manipulator, and pulling out the obstacle through hoisting equipment on the ship. According to the technical scheme, the manipulator and the shearer are arranged to replace a diver to complete submarine cable obstacle removing operation, the submarine cable operation and maintenance efficiency is improved, and the safety risk of obstacle removing operation of workers is reduced.

Description

technical field [0001] The invention relates to the field of operation and maintenance of submarine cables, in particular to a method for removing obstacles of submarine cables by a cabled underwater robot. Background technique [0002] The traditional method of removing submarine cable obstacles basically adopts the artificial launching operation mode of divers. Divers explore in different areas and sections. Due to the limitations of human body functions and diving equipment, it is difficult for operation and maintenance personnel to dive below 40m to operate the submarine cable. The situation is checked and maintained, and the physical exertion of divers is extremely high during manual operations, the risk factor is high, and the work efficiency is very low. [0003] At present, the underwater robot is only used for the survey of the submarine cable. It only adopts the avoidance method for the obstacles around the submarine cable, and does not take measures for the obstac...
