METHOD FOR COLLECTING MANGANESE NODULES OF DEEP SEA MANGANESE NODULES COLLECTING ROBOT

摘要

The present invention relates to a method for collecting manganese nodules in deep sea, specifically to a method of a collecting robot for collecting manganese nodules using the Coanda effect at a colleting part of a collecting robot. The method includes a step (a) pumping sea water with a plurality of hydraulic jet spray nozzle by a pump; a step (b) of discharging sea water to a curved flow table by the spray nozzle in the step (a); a step (c) of forming water jet fluid long the flow table and diffusing; and a step (d) of flowing levitated manganese nodules on the sea-bed into a duct.
