Underwater distribution type all-weather seabed mining system with sub-collection and conveying functions

Abstract

The invention relates to a separate collecting and conveying underwater distributed all-weather seabed mining system which is composed of autonomous mining vehicles, a seabed mine cabin and transfer device, a bottom-supported mineral lifting device, a seabed power distribution and control center, a suspension hose, a vertical pipe, an underwater floating device and a mining operation supporting ship. Collecting operation is carried out in the respective areas at the same time, and collected minerals are conveyed to ore cabins in the respective operation areas through suspension pipes to be stored; the seabed mineral storage and transfer device is used for simultaneously conveying the minerals to the bottom-supported mineral lifting device through pipelines after the mineral cabins in all the operation areas are full of the minerals, and the minerals are intensively conveyed to the underwater floating device through a vertical pipe by the bottom-supported mineral lifting device; the suspension hose is connected with the underwater floating device and the mining operation supporting ship to convey minerals from the underwater floating device to the mining operation supporting ship; the ore operation support ship conveys minerals to the water surface ore sand transport ship which is regularly in place; and the submarine power distribution and control center provides power supply for all underwater systems.

Description

technical field [0001] The invention relates to the technical field of marine engineering and seabed mineral development, in particular to a sub-collection and transportation underwater distributed all-weather seabed mineral development system. Background technique [0002] Deep-sea mineral resources such as polymetallic nodules, polymetallic sulfides and cobalt-rich crusts are rich in a large amount of precious metal elements. These metal elements are widely used in modern industry, cutting-edge technology and sophisticated weapons, and are indispensable key strategic raw materials . Research on deep-sea mining models belongs to cutting-edge technology research. At present, the deep-sea mining mode that is recognized by the international community as the most advantageous commercial mining in the future is: self-propelled crawler concentrator, slurry hydraulic lift + self-propelled concentrator pipeline lift mining mode. This model has been verified by the United States, ...

AI Technical Summary

Problems solved by technology

[0003] The water surface platform of the existing deep-sea mineral development model works in series with the slurry hydraulic lifting pipeline and self-propelled ore collector, and is attached to several umbilical cables for power supply and communication. The use of high-power propulsion systems is also difficult to withstand harsh sea conditions such as typhoons, and it is impossible to achieve safe surface operations and underwater all-weather operations. The release and recovery of underwater pipelines and mining machines before and after typhoons also seriously affect operating efficiency.

The surface mining ship of this model is a floating working platform for the deployment of the entire underwater mining equipment, operation support, and mineral water surface treatment, storage, and export. Most of the trial mining at sea is a short-term behavior based on technical principles and design verification. Therefore, out of economic considerations, the mining ships at this stage are basically transformed from old ships according to the requirements of sea trial verification. They are specialized and integrated. The degree of modularization and intelligence is low, and it does not meet the actual engineering requirements of commercial mining.
