The present invention relates to an internal inline screw small hydropower generation device capable of being installed in a water treatment facility such as a water and sewage treatment plant or a duct in a small river, and generating and supplying power through power generation converting movement energy into electric energy by using power (pressure, flux) of water flowing in the duct. To this end, the small hydropower generation device, producing electric power by using water power, includes: a water duct (100) including an inlet (101) and an outlet (102) in both sides to form water pressure by making water flow inside; a rotor (200) rotated by using the water pressure of the water duct (100); and a power generating unit (300) receiving rotational force of the rotor (200) through an operating shaft (310), and producing electric power by using a power generator (330) operated by the rotational force. The rotor (200) comprises: a rotor inner wheel (210) combined with the operating shaft (310); a rotor outer wheel (220) having an internal diameter of which size is the same as the diameter of an inner wall of the outlet (102) on the edge of the inner wheel (210); and multiple rotor wings (230) combined in a radial shape between the rotor inner wheel (210) and the rotor outer wheel (220). |
