Title: HYDRAULIC POWER GENERATION DEVICE
Abstract:
This hydraulic power generation device is provided with: a hollow shaft (32), to the outer periphery of which a spiral blade (30) is provided; a power generator (40); and a transmission (50). The hollow shaft (32) is rotatably supported by an anchor shaft (20) so as to be rotated by a water flow oriented toward the spiral blade (30). The power generator (40) is provided to the interior of the hollow shaft (32). The transmission (50) is provided to the interior of the hollow shaft (32) and transmits drive force coming from the hollow shaft (32) to a rotor (42) of the power generator (40).
