PROBLEM TO BE SOLVED: To prevent foreign materials such as dusts and floating substances from being adhered to propellers without increasing work burden of a user.SOLUTION: A flowing water power generation device (1) for changing rotational energy of propellers (12a, 13a) into electrical power by rotating the propellers with flowing water is constituted in such a way that there is provided a supporting part (11) supporting propellers to expose at least a part of each of the propellers on the water surface and immerse the residual portions of the propellers below the water surface, and plunging from surrounding air into the water and escaping from submerged state to the surrounding air of blades (35, 45) of the propellers are alternatively repeated to cause some foreign substances (54) to be easily removed from the propellers.
【課題】使用者の作業負担を増やすことなく、プロペラに対するゴミや浮遊物等の異物の付着を防止すること。【解決手段】水流によってプロペラ(12a、13a)を回転させることで、プロペラの回転エネルギーを電力に変換する流水発電装置(1)を、プロペラの少なくとも一部分を水面上に露出させ、プロペラの残りの部分を水面下に水没させるようにプロペラを支持する支持部(11)を備える構成にし、プロペラのブレード(35、45)を空中から水中への突入と水中から空中へ脱出を交互に繰り返させてプロペラから異物(54)を離れ易くした。【選択図】図1
