Claim 0:
1. A pumped-storage hydropower generation tower employing conduit turbines installed in multiple stages, comprising:
a pump (400) piped to a pumping pipe (410) to pump water contained in a lower reservoir (300) to an upper reservoir (200);
a water-guide conduit line (500) connected to an inlet water-guide conduit (510) from a bottom surface of one side of the upper reservoir (200) and extending to a position of the lower reservoir (300) along a spiral inclined passage (100) to allow a flow for power generation to pass therethrough; and
a conduit turbine unit (600) comprising:
a drive shaft (2) extending through a center of a conduit (22), the flow passing through the conduit (22);
a conduit support body (4) arranged to rotatably support the drive shaft (2), and having an arm (6) extending toward an inner surface of the conduit (22);
a propeller (7) fixed to the drive shaft (2) in between the conduit support body (4) and rotated by movement of the flow; and
a generator (10) configured to generate electricity by rotational power received from the drive shaft (2),
wherein the conduit turbine unit (600) has at least two conduit turbine units (600) disposed in the water-guide conduit line (500) in multiple stages.
