To provide a device for lifting seabed mineral resources up to a surface of the sea by hermetically filling liquid with smaller specific gravity in liquid phase than water at an ordinary temperature in a buoyancy tank and using its buoyancy, with respect to a system for collecting seabed mineral resources and lifting them.SOLUTION: An underwater vehicle capable of autonomous cruising is configured to: load ballast for cancelling buoyancy of a buoyancy tank in a cargo chamber when descending below the sea level; descend by making a state that specific gravity of an entire seabed resource lifting device is heavier than 1.0; and float up by making a state that specific gravity of the entire seabed resource lifting device is lighter than 1.0 by exchanging the ballast with the mineral resources at the seabed, wherein the ballast is replaced with the mineral resources at the seabed by using gravity.SELECTED DRAWING: Figure 2

    【課題】海底の鉱物資源を採取し揚収するシステムに関し、常温で液相の比重が水より少ない液体を浮力タンクに密閉充填しその浮力を利用して海底の鉱物資源を海面まで揚収する装置に関する。【解決手段】海面よりの降下時には貨物室に浮力タンクの浮力を打消すバラストを積み、海底資源揚収装置全体の比重を1.0より重い状態として降下し、海底でバラストと鉱物資源を交換して、海底資源揚収装置全体の比重を1.0より軽い状態として浮上する自律航走可能な水中航走体であり、海底においてバラストと鉱物資源とを重力を利用して置換する。【選択図】図2
