Deep sea mineral resource exploration system

Abstract

The invention discloses a deep sea mineral resource exploration system which comprises a mother operation ship, a mining system as well as a floating platform, wherein the floating platform is connected with the mother operation ship in a detachable manner; the mining system is connected with the floating platform; the mining system or the floating platform is connected with a submerging control device for enabling the floating platform to submerge under water. The deep sea mineral resource exploration system can shelter from the wind flexibly and conveniently without disassembling the whole system, can rapidly and flexibly respond to complex weather condition such as typhoon, and has the advantages of long service life, high production efficiency, good production operation continuity and the like.

Description

technical field [0001] The invention relates to the technical field of underwater mining equipment, in particular to a deep-sea mineral resources mining system. Background technique [0002] The 21st century is the ocean century. The ocean is the strategic resource base of energy, minerals and organisms needed for sustainable development of human beings. Among them, the international seabed area accounts for 49% of the earth's surface area, containing polymetallic nodules, cobalt-rich crusts and polymetallic sulfides. Abundant mineral resources and biological resources such as natural resources are reliable replacements for increasingly depleted land resources. [0003] The mining technology of marine mineral resources first started in the 1970s. Due to the rapid development of the western industrial society, the demand for resources is increasing. In order to seize the seabed mineral resources, technologically developed countries have carried out a large number of polymetal...

Problems solved by technology

When installing mining equipment, it is necessary to arrange and install the ore collection vehicle, conveying hose, intermediate cabin, hoisting pump, and conveying riser step by step in sequence. This installation method has extremely high requirements on the pipeline, and each functional block cannot be disassembled , it is difficult to maintain, and the service life of each system is not equal, forming a short board

In addition, the polymetallic nodule mining area is a typhoon-prone area, and the meteorological conditions are changeable. Most of the existing mining systems are tested in a good marine environment. When encountering severe weather such as strong winds and waves, the mining ship needs to tow the entire system to avoid the wind and waves. , or recover the equipment step by step to the ship for shelter from the wind, the disassembly and assembly of the system is time-consuming, which seriously affects the continuity of operations

Moreover, the manufacturing cost and maintenance cost of the existing mining system are high, the operation requirements are high, and it is sensitive to sea wind and waves
