Description

Deep sea ore transportation system

Technical Field

The invention relates to the technical field of transportation equipment, in particular to a deep sea ore transportation system.

Background

There are two methods of transporting submarine ore to the sea, the grab method and the slurry method, respectively. The grab bucket method is to slowly hoist a large-volume grab bucket from a ship (on a platform) to grab submarine minerals, then recycle the grab bucket to the ship (on the platform) through the crane, and repeatedly grab the grab bucket to collect mineral resources. The slurry method is to break up the ore into smaller particles by an underwater robot, then suck the slurry and the ore together to a ship (on a platform) through a lifting pipeline, and separate the slurry and the ore on the ship (on the platform). Both of these have the same drawbacks: the single operation time is slow, the operation efficiency is low, the energy consumption is high, and minerals need to continuously apply work from the deep part of the sea bottom to the sea surface.
