液体揚水循環装置
Document Type and Number:
Japanese Patent JP6671061
Kind Code:
B2
Abstract:
To provide a liquid pumping and circulating device capable of performing urban type hydraulic power generation by making potential energy of a water heat pressure or the like into hydraulic power, efficiently taking it out and performing pumping and circulation.SOLUTION: A liquid pumping and circulating device comprises multiple double-axis rotary piston devices in each of which a pumping erected part, a downflow erected part and a flow direction converting part are defined so as to keep a liquid-tight state coaxially within one longitudinally long cylindrical tank for a pressure for which potential energy of a water head pressure or the like is further increased by a hydraulic pressure jack. A conical spiral blade flow passage is provided in a pressure maintenance function by making both the pumping part and the downflow part gradually narrow in a flow direction, and a lower part of the cylindrical tank is immersed in water to an extent in a liquid tub that is opened into the atmosphere, and brought into tight contact with a lowest end of the downflow part. In the multiple double-axis rotary piston devices, one double axis rotary piston device for driving repeats injection and discharge of a pressure fluid and integrally rotates drive shafts of the pumping erected part and the downflow erected part, such that a fixed quantity of water is pumped and circulated, and in the other multiple double-axis rotary piston devices, generators are driven.SELECTED DRAWING: Figure 11
