Document Type and Number:
Japanese Patent JP2018028312
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a water intake means for deep water that is utilized at a deep water temperature difference power generation device.SOLUTION: This invention relates to a deep water intake means comprising a deep water storage tank provided with a water discharging opening on a water surface and a deep water intake structure provided with a riser pipe having a deep water intake opening at the other end at a lower part of the deep water storage tank, an inner passing-through member having a specific gravity lower than that of water to close the water discharging opening in which it passes through the inside part of the deep water storing tank and having the inner water surface that is the same surface out of the deep water storage tank, air above the inner through-pass member in the deep water storing tank is discharged to cause the inner through-pass member and the water surface in the deep water storage tank to be moved more above the water surface out of the deep water storage tank, thereby either sea water or lake water is discharged out of the water discharging opening to outside the deep water storage tank, either sea water or lake water in the riser pipe is moved upward to cause either the sea water or the lake water in the deep water intake structure to be circulated.SELECTED DRAWING: None
