Floating submarine high-precision transient electromagnetic detection system

Abstract

The invention discloses a floating submarine high-precision transient electromagnetic detection system which includes a deck control platform, an ROV (Remote Operated Vehicle) near-seabed work platform, an underwater information acquisition control system and an umbilical cable. The ROV near-seabed work platform is connected with the deck control platform through the umbilical cable. The underwater information acquisition control system is set on the ROV near-seabed work platform. An electromagnetic detector is mounted on an ROV, and a navigation and positioning system is added to the detector, so that the electromagnetic detector can reach a specified detection point and carry out detection according to a specified trajectory. The height of the antenna of the detector relative to the seabed is accurately controlled, so that effective, fast and convenient implementation of a deep-sea transient electromagnetic instrument is realized. The floating submarine high-precision transient electromagnetic detection system has the ability of submarine electrical structure fine exploration, is suitable for rapid exploration of polymetallic sulfide and cobalt-rich crust deposits at the seabed,and provides more scientific guidance for deep-sea mining vehicles to walk and exploit the seabed in the later stage.

Description

technical field [0001] The invention belongs to the technical field of seabed electromagnetic detection, and in particular relates to a floating seabed high-precision transient electromagnetic detection system. Background technique [0002] In recent years, mineral resources have become increasingly scarce and exhausted. Countries around the world have turned their attention to the ocean. The development and utilization of marine resources is an inevitable trend for the development of human society to demand new resources. [0003] Deep seabed polymetallic sulfides are considered to be a kind of seabed polymetallic mineral resources with far-reaching significance because of their shallow water depth, relatively concentrated mining areas, relatively simple smelting process, and low smelting costs. In view of the special deep-sea exploration environment, the "rich and shallow" characteristics of seabed hydrothermal sulfide ores, and the geological task requirements of "discove...
