Description

Technical field: [0001] The invention relates to a polymetallic nodule non-continuous chain-bucket deep-sea mining system. Background technique: [0002] Mineral resources, also known as mineral resources, refer to those formed through geological mineralization, naturally occurring in the crust or on the surface, buried underground or exposed on the surface, in solid, liquid or gaseous state, and have development and utilization value A collection of minerals or useful elements. [0003] In recent years, with the development of economy, terrestrial mineral resources have been difficult to meet human demand for mineral resources, so human beings need to explore new ways of supplying mineral resources. The seabed is rich in mineral resources, and rational mining of marine mineral resources can help solve the problem of insufficient supply of land mineral resources; polymetallic nodules are rich in manganese, iron, nickel and other dozens of elements, and are a kind of extreme...

AI Technical Summary

Problems solved by technology

The complex marine environment, the fragile seabed ecological environment, the collection of seabed minerals, and the transportation of collected minerals all pose great challenges to deep-sea mining technology.

[0004] At present, most of the mining lifting methods in the world use pipelines for lifting. It is difficult to fix the pipeline structure, which is not convenient for installation, transportation and recycling. It also poses a huge challenge to the design of pipelines and delivery pumps. It will bear complex marine environmental loads such as wind, waves, and currents, which poses a huge challenge to safe operations; the towing movement of sea surface operation ships and submarine mining vehicles causes complex heave effects, combined with too long lifting pipes, it is difficult to realize multi-mining vehicles. Collaborative operation; the pipeline hoisting system is expensive, and it is difficult to realize the rapid recovery of the hoisting pipeline in the extreme marine environment. Discarding will cause great economic losses and affect the mining efficiency

[0005] The existing continuous rope-bucket-elevating deep-sea mining system relies on the self-weight of the rope bucket and the dragging of the rope to scoop up polymetallic nodules from the seabed, which has low collection efficiency and resource recovery efficiency, and has a great impact on the seabed environment; and lacks tension. In the face of complex wind, wave, current and other ocean loads, as well as the heave and tow of the sea surface operation ship, it is easy to cause the rope to be entangled, resulting in unstable performance and poor economy of the mining system
