A magnetic ROV umbilical cord cable

Abstract

A magnetic ROV umbilical cord cable The first magnetic umbilical cord cable is structured as follows: comprises three first cables in a central position, one side of the first cable is provided with afirst single-mode optical fiber, three first cables and an outer part of the first single-mode optical fiber are wrapped with silicon steel sheets, a coil is wound on the silicon steel sheets, two ends of the coil are respectively connected with a positive electrode and a negative electrode, and the outer wrapping of the silicon steel sheets is provided with a first buoyancy material; The gap ofthe three first cables is filled with a first filling material; The second magnetic umbilical cord cable is structured as follows: comprises a second single-mode optical fiber in a central position, the exterior of the second single-mode optical fiber is provided with three second cables arranged in a triangular staggered arrangement, The second cable and the second single-mode optical fiber are wrapped with a second buoyancy material, the second buoyancy material is filled with a second filling material at a gap at an inner position of the second buoyancy material, the outer portion of the second buoyancy material is wrapped with a carbon steel ring, and the outer portion of the carbon steel ring comprises a third buoyancy material. Work reliably.

Description

technical field [0001] The invention relates to the technical field of underwater cable-controlled operation robots, in particular to a magnetic ROV umbilical cable for multi-type ROV underwater cooperative operations that can prevent entanglement. Background technique [0002] In deep-sea exploration and deep-sea construction, the cable-controlled operating robot (Remotely Operated Vehicle, referred to as ROV) is deployed to the deep seabed through the retractable winch and other deck mechanical equipment of the surface mother ship, so as to complete specific tasks. The retractable winch passes Control the retractable length of the umbilical cable to adjust the operating radius of the ROV, and complete the power transmission and data communication of the ROV through the umbilical cable. As the depth of deep-sea operations gradually increases, the length of the umbilical cable of the ROV also increases, and the length of the umbilical cable released from the winch of the sur...

Problems solved by technology

In order to improve the operational efficiency of a single voyage of a surface mother ship, it is more and more urgent to deploy two or more types of ROVs from the surface mother ship for collaborative operations. Usually, one type of ROV is deployed from the port side of the deck to the seabed. Another type of ROV is deployed to the seabed from the starboard side of the deck surface. However, when two types of ROVs are deployed to the seabed at the same time, each type of ROV is connected to an independent umbilical cable with a length of more than 1,000 meters, and the umbilical cable of the ROV is usually designed as Neutral buoyancy, during the cooperative operation of two types of ROVs, the two independently retractable umbilical cables are easily entangled together, forming a twisted shape, which causes the termination of the operation task, and even causes the umbilical cable to become knotted and cannot be untied, resulting in Risk of ROV loss
