DIMPLED LIFTING PIPE FOR MINING DEEP-SEA MINERAL RESOURCES, CAPABLE OF REDUCING REACTION TO REDUCE INFLUENCE DUE TO THE FLOW OF SEAWATER

摘要

PURPOSE: A dimpled lifting pipe(1) for mining deep-sea mineral resources is provided to reduce reaction due to the current of the deep sea by forming dimples on the surface of a lifting pipe to generate turbulence.;CONSTITUTION: A dimpled lifting pipe for mining deep-sea mineral resources comprises a collector, a lifting pipe, and a lifting pump. Multiple dimples are formed on the girth surface of the lifting pipe. The multiple dimples generate turbulence to reduce drag coefficient and reduces vibration due to the current of the deep sea.;COPYRIGHT KIPO 2010
