PROBLEM TO BE SOLVED: To improve power generation efficiency by reducing a loss of fluid energy by a vane.SOLUTION: A water flow power generation device in an embodiment comprises a power generator, a rotary vane, and a stationary vane. The rotary vane rotates under a water flow, and generates a driving force of the power generator. The stationary vane is provided on an upper stream side of the water flow than the rotary vane, and changes a direction of the water flow to a direction of a chord line of the rotary vane. |
