Abstract

The invention provides a child-mother ROV system. The child-mother ROV system comprises an ROV mother unit capable of sailing and / or walking underwater and an ROV child unit connected with the ROV mother unit through a first cable for detecting the wall surface of an object in water, wherein the ROV mother unit is net negative buoyancy in water, and the friction force of the wall surface to the ROV mother unit is larger than the sum of the impact force of water flow to the ROV mother unit, the first cable and the ROV child unit, so that the ROV mother unit can be anchored in water. The ROV mother unit in the child-mother ROV system provided by the invention has good underwater navigation and / or walking and anchoring capabilities; a cable, an ROV child unit and the like can be carried to adesignated position and anchored, the ROV child unit can perform small-range regional operation near the ROV mother unit, and the ROV child unit and the ROV mother unit are matched so that the comprehensive capacity and the applicability can be remarkably improved.

Description

technical field [0001] The invention relates to a cable-controlled underwater robot, in particular to a cable-controlled underwater robot with child and mother units. Background technique [0002] At present, cable-controlled underwater vehicles (Remotely Operated Vehicles, ROV) are usually only a single body, and most of them are designed to meet the needs of a certain aspect. However, for the maintenance of narrow and long underwater tunnels, culverts and other water conservancy facilities, a single ROV cannot meet the operational requirements of anti-flow and fixed-point observation at the same time. Contents of the invention [0003] In view of the problems existing in the prior art, the present invention provides a mother-son ROV system, which is characterized in that it includes: [0004] An ROV parent unit capable of navigating and / or walking underwater; [0005] An ROV subunit connected to the ROV parent unit through a first cable for detecting the wall of an obj...
