DEVICE FOR EXTRACTING ENERGY FROM FLOWING LIQUID

Japanese Patent JP2017020511

A

PROBLEM TO BE SOLVED: To provide a device capable of stably extracting energy while keeping a vertical position in retention of liquid.SOLUTION: A device includes a supporting device (12) rotatably connected to a rotating shaft (18, 30), and a turbine device (1) including at least one spiral turbine (2, 4). A shaft of each turbine is connected to an energy converter, the turbine device includes a proximal end and a distal end, the proximal end is rotatably connected to the supporting device, and the distal end is freely movable along a circular passage in a flowing liquid. As the rotating shaft is disposed vertically to the circular passage, an operation angular position about the rotating shaft can be adjusted in using the turbine device. Further the distal end of the turbine device (1) includes at least one horizontal girder (7) to stabilize the operation angular position of the turbine device, and the horizontal girder has a surface to hydrodynamically increase vertical force in accordance with increase of an operation angle about the rotating shaft of the turbine shaft.SELECTED DRAWING: Figure 1
