Cabled shuttle ore hauling submersible for deep sea mining and operation method thereof

Abstract

The invention relates to a cabled shuttle ore hauling submersible for deep sea mining and an operation method thereof. The submersible comprises a carrier frame, the interior of the carrier frame is divided into a buoyancy material arrangement area, an adjustable ballast water tank arrangement area, an equipment arrangement area and a cargo hold area, and an ore pulp cutter suction mechanical armis installed at the front part of the bow of the carrier frame; and a pumping head of the ore pulp cutter suction mechanical arm feeds ore pulp into the cargo hold area through an ore pulp pump. During operation, the shuttle ore hauling submersible is in a cabled mode, so that the influence of hard pipes of a pipeline lifting system on an operation mother ship and a mining robot is avoided; electric power and control problems are solved, and the operation capability of the submersible is improved; the cutter suction mechanical arm is adopted to self-suck minerals to the ore bin, underwater butt joint operation of the shuttle ore conveyor and the relay station is omitted, and the underwater operation difficulty is reduced; a high-capacity ballast water tank and a high-flow seawater pump areadopted to replace the weight of minerals, so that unpowered upward floating and diving of the shuttle ore hauling submersible are realized; and the use of a large-tonnage hoisting device can be avoided by the semi-submersible ore unloading mother ship, and the feasibility and efficiency of water surface ore unloading are effectively improved.

Description

technical field [0001] The invention relates to the technical field of mining equipment for deep-sea mineral resources, in particular to a cable-shuttle ore-transporting submersible for deep-sea mining and an operating method. Background technique [0002] The main modes of deep sea mining are: drag bucket type, continuous rope bucket type, shuttle boat type, mining vehicle plus pipeline lifting type. Among them, the mining vehicle plus pipeline conveying mining system is composed of a submarine mining vehicle, a mining ship and a pipeline lifting system. At present, most countries are engaged in the research of this mining system. Theoretically, the pipeline lifting mode can collect and transport minerals at the same time, with large production capacity and simple process. However, this model also faces many technical challenges, especially from the limitations of the lifting pipeline system, such as: using multiple slurry pumps to relay the mixed fluid of ore and seawater...

AI Technical Summary

Problems solved by technology

[0007] In view of the shortcomings in the above-mentioned existing production technology, the applicant provides a cabled shuttle ore transport submersible and an operation method for deep sea mining, which solves the problem of using the shuttle ore transport submersible to lift the mineral mining system. There are three technical problems of limited energy, the need for underwater docking to complete the operation of mineral transfer, and the need to hoist to the mother ship for unloading
