摘要

The independent device for collecting and lifting poly-metallic nodules situated at greater depths in the ocean, comprises a branch (1) that maintains a collection net (2) over the bottom of the ocean, a guidance device for modifying hydrodynamism of the independent device, and a combustion chamber (7) containing thermite or thermate intended to reheat sea water under lifting parachute (5) and a bottle of air under high pressure. The chamber further contains components to generate a complementary gas for increasing the volume of gas in the lifting parachute. The independent device for collecting and lifting poly-metallic nodules situated at greater depths in the ocean, comprises a branch (1) that maintains a collection net (2) over the bottom of the ocean, a guidance device for modifying hydrodynamism of the independent device, and a combustion chamber (7) containing thermite or thermate intended to reheat sea water under lifting parachute (5) and a bottle of air under high pressure. The chamber further contains components to generate a complementary gas for increasing the volume of gas in the lifting parachute. The lifting parachute is insulated and sealed to conserve heat and liquid trap so that water vapor produced is condensed. The poly-metallic nodules are trapped while lifting the net. The net has a square form equipped with pockets.
