Abstract:
Provided is a hydropower generation device that can be readily withdrawn from a waterway by human power and can be reliably installed in a planned location. This hydropower generation device comprises: at least one hydropower generation module (3) having impellers (2) that each convert hydropower to rotational force; a generator (6) that generates power using the rotation of the impellers (2) of the at least one hydropower generation module (3); at least one cradle (11) that supports each of the hydropower generation modules (3) among the at least one hydropower generation module (3); and a fixing frame (10) fixed in the waterway and supporting the at least one cradle (11). The at least one cradle (11) is rotatably supported across: a position in which the hydropower generation module (3) supported by that cradle (11) has a lower end of an impeller (2) in a submerged posture positioned lower than the water surface of the waterway, relative to the fixing frame (10); and a position in which the hydropower generation module (3) supported by that cradle (11) has the entire impeller (2) positioned higher than the water surface of the waterway.
