Dispersed deep-sea partial trial-mining system

Abstract

The invention relates to a separated blue water local mine production system, belonging to the underwater project technique. It comprises: a surface main ship, a mine producing diving device, and a lifting system. Wherein, the lifting system is formed by several lifting diving devices, which are unmanned non-cable diving devices; the mine producing diving devices are unmanned cable diving devices via the umbilical cord cable connected with the main ship, while the umbilical cord cable comprises the electric and information transmission channel; when lifting the diving devices, the mine producing diving devices and the surface main ship via the water sound to position and transmit information; when in working, the mine producing diving devices produce mine at the bed and lifting diving devices move between the mine producing diving devices and the main ship to transfer collected mine sample, and the fully loaded lifting diving devices is guided to the main ship via the mine producing diving devices; and the empty lifting diving devices is guided to the mine producing diving devices from the main ship. The invention is flexible with lower cost, high practicability, the application for variable mine sources as multi-metal concretion, abundant cobalt crustization and metallic sulfide beds.

Description

technical field [0001] The invention relates to a system in the technical field of underwater engineering, in particular to a decentralized deep-sea partial test mining system. Background technique [0002] Deep sea mining faces complex technical and economic accounting issues. A proposed deep-sea mining scheme is a shuttle mining machine-based mining system consisting of a surface mother ship and multiple shuttle mining machines. Shuttle mining machines have to perform mining and ore transportation tasks at the same time, and their technical requirements face greater conflicts, and their operating efficiency is low. At present, the more popular deep-sea mining system solutions are composed of three parts with clear division of labor, namely the mother ship (or platform), mining machine and pipeline hoisting system. The mining machine can be floating in the water near the seabed, crawling on the seabed, or towed on the seabed. The main body of the pipeline hoisting system ...

AI Technical Summary

Problems solved by technology

This system has a pipeline-type conveying device, which requires a high-power conveying device and a dedicated mother ship. The initial investment is high. The mining machine is also responsible for the task of transporting ore samples to the transfer cabin. It is difficult to balance the needs of transportation and mining. The mining machine adopts cableless The form, the continuous working time of the seabed is short, the adaptability to complex environments is poor, the mining machine works suspended in water, and cannot be used for mining such as hydrothermal deposits, etc.
