<p>This hydroelectric generator device has increased generation efficiency in efficiently converting the potential energy of falling water to electrical energy, can suppress the installation space to a small size, can have a simplified configuration, and can have a reduced cost. Drive water turbines (21) are attached in a plurality of vertical stages to a rotary shaft (20) disposed along the center line of a cylindrical space, and each drive water turbine (21) is rotated by means of the water flow dropping within the cylindrical space. The drive water turbines (21) are provided with a plurality of water flow vanes (24) that extend diagonally vertically in the same direction as the direction of rotation along the inner peripheral surface (12) of the cylindrical space. A rectifying means (30) is provided vertically between the drive water turbines (21) in a manner such that the water flow, which impacts the water flow vanes (24) of an upper drive water turbine (21) causing the drive water turbine (21) to rotate, and then drops downwards diagonally in the reverse direction from the direction of the rotation, is converted to a linear water flow that impacts at a certain angle opposing the oblique surface at the surface of the water flow vanes (24) of a lower drive water turbine (21).</p> |
