Deep sea cobalt crust cutting device based on high pressure water jet

Abstract

The invention relates to the technical field of underwater robots and provides a deep-sea cobalt crust cutting device based on high-pressure water jet flow. The deep-sea cobalt crust cutting device comprises a high-pressure water conveying system, high-pressure water jet flow nozzle units and nozzle supports. The high-pressure water conveying system is in connection with the high-pressure water jet flow nozzle units, the tops of all nozzles in the high-pressure water jet flow nozzle units are arranged on supporting frames, the bottoms of all the nozzles are spherical, and all the nozzles are connected with the nozzle supports through spherical hinge structures correspondingly; and the nozzle supports are each of a hollow frame structure, spherical shells are fixed into frames, jet holes are formed in the spherical shells, and the lowest points of the outer surfaces of the spherical shells are higher than the bottoms of the frames. The deep-sea cobalt crust cutting device based on the high-pressure water jet flow is suitable for the landform of a seafloor cobalt crust of the South China Sea, cutting precision can be improved, and the ore dilution rate is reduced.

Description

technical field [0001] The invention relates to a technology in the field of underwater robots, in particular to a deep-sea cobalt crust cutting device based on high-pressure water jets. Background technique [0002] People's demand for energy continues to rise, and land mineral resources are constantly being consumed. Therefore, people gradually turned their attention to the ocean. Metal cobalt is an important raw material for the production of various alloys with special properties, such as anti-corrosion alloys. Seabed cobalt-rich crusts are considered to be an important source of cobalt crusts, and the cobalt content of cobalt-rich crusts can reach 1%, which is much higher than that of terrestrial cobalt deposits. [0003] The traditional ore mining method is to use a reamer head for ore cutting, but in practical applications, the reamer head wears quickly and its life is very low. At the same time, the ore dilution rate of reamer cutting is relatively high, and the p...

AI Technical Summary

Problems solved by technology

[0003] The traditional ore mining method is to use the reamer head to cut the ore, but in practical application, the reamer head wears quickly and the service life is very low

At the same time, the ore dilution rate of reamer cutting is high, and the mechanical vibration problem is serious

In contrast, the current continuous development of water jet cutting technology can solve the above problems very well, but so far there is no precedent for water jet application in the collection of deep sea cobalt-rich crusts
