Exploitation system for deep sea mineral resources

Abstract

The invention discloses an exploitation system for deep sea mineral resources. The exploitation system comprises an underwater mineral collection subsystem, a mineral transfer subsystem, a water surface support subsystem, an underwater control subsystem and a supporting guarantee subsystem, wherein the underwater mineral collection subsystem comprises mining submersible groups; the mineral transfer subsystem comprises a lifting submersible; the underwater control subsystem comprises a bathyscaph, and a nuclear power station is arranged in the bathyscaph; the supporting guarantee subsystem comprises a maintenance management submersible and a communication and navigation positioning device; the bathyscaph is connected with the mining submersible groups and the maintenance management submersible through umbilical cables and supplies energy and control signals to the mining submersible groups and the maintenance management submersible. According to the exploitation system for the deep sea mineral resources, the underwater subsystems are not required to be powered by the subsystems above water, once meeting severe weather such as heavy storm waves on the sea during working, the subsystems above water can be transferred to other places to avoid stormy waves while the underwater subsystems can continue normal operation, the operation requirements are not high, and the exploitation system is insensitive to the stormy wave weather on the sea.

Description

technical field [0001] The invention relates to the technical field of marine mineral resource mining equipment, in particular to a deep sea mineral resource development system. Background technique [0002] The deep seabed contains extremely rich mineral resources, among which polymetallic nodules, cobalt-rich crusts and polymetallic sulfides are the most valuable for development. In recent years, with the rapid development of my country's economy, the demand for resources has also increased. With the significant improvement of economic strength, the marine industry has developed rapidly, providing a good foundation for the development of deep sea mining. [0003] Since the middle of the last century, extensive research has been carried out internationally on deep-sea mining technology, and various technologies such as drag bucket type, continuous chain bucket type, pipeline lifting type, and shuttle carrying type based on "surface floating platform" have been proposed.

Problems solved by technology

[0005] The purpose of the present invention is to provide a deep-sea mineral resources development system to solve the problem that the existing marine mineral resource mining device's surface mining ship tows the underwater system to carry out the collection of underwater mineral resources. Mining ships need to tow the entire system to avoid wind and waves, which requires high operational requirements and is sensitive to sea wind and waves.
