Problems solved by technology

Due to the high water content of the seabed sediments is extremely soft, in order to reduce the grounding specific pressure of the ore collector, the crawler-type traveling mechanism must use a wider crawler belt to provide sufficient support. The mining machine has slipping, large turning radius, serious subsidence, and even being trapped in the sediment. At the same time, there is a problem that the height of the mining mechanism installed on the mining vehicle cannot be controlled from the bottom, which greatly reduces the mining efficiency of the mining mechanism.
Although the Archimedes spiral walking mechanism runs smoothly, it still has the disadvantages of large turning radius, easy slipping and large disturbance to the seabed
Therefore present seabed self-propelled mining vehicle of development all does not solve the problem of seabed walking mechanism

Abstract

The invention discloses an oceanic mineral resource exploitation device and exploitation method and aims to overcome the technological difficulty of the existing submarine mining vehicle and the pipeline waterpower lifting exploitation system. The exploitation device comprises a water surface mining vessel, a lifting pipe, a lifting electric pump station, a hose, a mineral crushing mechanism and a mining mechanism, wherein a plurality of perturbance jet flow nozzles, a plurality of ascending jet flow nozzles and a flow guide pipe are mounted on the mining mechanism; the flow guide pipe is communicated with the feeding hole of the mineral crushing mechanism; the lifting pipe, the lifting electric pump station, the hose and the mineral crushing mechanism are sequentially connected with the flow guide pipe in series to form an ore pulp lifting passage; the hose is fixed onto an ROV; the ROV is connected with the mining mechanism through a connecting device. The oceanic mineral resource exploitation device is not limited by the complicated terrain and gradient at the bottom of the sea, avoids the slipping and sinking of the underpan of the submarine mining vehicle on a settled layer, greatly reduces the disturbance of mineral mining to bottom sediments, and also solves the problem that the terrain clearance of the mining mechanism is difficult to control.

Description

technical field [0001] The invention relates to the field of marine mineral resource mining methods and related equipment, in particular to a marine mineral resource mining device and a mining method, which are used for collecting deep seabed minerals and transporting the seabed minerals to a surface mining vessel. technical background [0002] As the most promising emerging industry in the 21st century, the mining of marine mineral resources has been widely valued by all countries in the world. The international seabed area, which accounts for 49% of the earth's surface, contains rich metal mineral resources such as manganese nodules, cobalt-rich crusts, hydrothermal sulfides, and polymetallic ooze. It is the largest potential strategy on earth that has not been fully understood and utilized by humans Resource base, its mining method has attracted great attention and great research enthusiasm in various countries. At present, three mining methods have been researched and de...
