A cleaning and probing tool for buried submarine cable and its operation method

Abstract

A cleaning and detecting tool for buried submarine cables and an operation method thereof. A cleaning and detecting tool for buried submarine cables includes a horizontally arranged module mounting plate, and an underwater motor is fixedly installed on the upper surface of the module mounting plate. The output end of the underwater motor is internally connected to the water pump through a coupling; one end of the lower surface of the module mounting plate is hinged with a hydraulic cylinder, and the other end of the lower surface of the module mounting plate is installed with a hanging probe arm assembly through a swing seat. A hook assembly is installed on the head of the hanging probe arm assembly. It realizes the functions of clearing buried objects, automatic release of hooks, automatic floating of marker floats, etc., and the work is stable and reliable.

Description

technical field [0001] The invention relates to the technical field of ROV operation tools for underwater robots, in particular to a cleaning and probing tool for buried submarine cables mounted on the bottom of an ROV and an operating method thereof. Background technique [0002] With the continuous expansion of communication, deep-sea submarine exploration and deep-sea energy development, the use of deep-sea submarine cables is becoming more and more extensive, especially in the fields of underwater information search and underwater observation network construction. The use and laying amount of deep-sea submarine cables huge. [0003] Nearshore submarine cables are usually buried, and deep-sea submarine cables are usually laid. However, as time goes by, the surface of submarine cables laid in deep sea will be buried by thick silt due to the influence of deep-sea currents. Whether it is a buried cable near the shore or a cable laid in the deep sea, it is often damaged by t...

Problems solved by technology

[0004] In the prior art, the commonly used method is to tow a tension anchor on the surface maintenance mother ship, and the tension anchor is towed on the seabed until the tension anchor is towed to the sea cable, hangs it up, and then salvages it ashore. The way of hanging the submarine cable, on the one hand, can only complete the towing of the submarine cable laid on the surface of the seabed, and it is difficult to complete the towing of the submarine cable buried at a certain depth. Other submarine cables on the seabed are towed and damaged, causing irreparable economic losses
