<p>PROBLEM TO BE SOLVED: To provide a wind turbine generating installation that has a simple structure and is inexpensive, and that is effective in a water channel or a river having a relatively high flow velocity and a relatively large flow volume.SOLUTION: This installation comprises two water channel walls for directing water of a river in a certain direction, a dam having an ascending inclined surface that is slowly inclined in a direction toward a water surface from a river bottom and a descending inclined surface that is inclined toward the river bottom from a peak of the ascending inclined surface, at least one water introducing duct disposed on the descending inclined surface of the dam, a lateral cross-section of a water inlet of the water introducing duct having a quadrilateral shape and being bent in an axial direction, and a propeller type water turbine generator connected to a water outlet of the water introducing duct. The propeller type water turbine generator is disposed so as to be parallel with the water surface of the river and above the water surface of the river at a normal occasion. A height from the river bottom of the water channel walls around the dam is higher than a height from the river bottom of the dam, and an inclination angle of the descending inclined surface of the dam is larger than an inclination angle of the ascending inclined surface.</p> |
