The present invention relates to a water turbine apparatus with bent wings, which is capable of being rotated on a vertical axis. In order to increase energy conversion efficiency by minimizing resistance to rolling caused by sound pressure generated behind the bent wings, the water turbine apparatus comprises: a water turbine (100) with a plurality of bent wings (104) attached to a drum (102) concentrically coupled to a water turbine shaft (101) rotatably fixed to a water turbine frame (112) such that the water turbine is housed in a water passage formed by a post (110) having a water turbine groove (111); a water turbine housing (114) configured to surround the water turbine (100) such that a water inlet port and a water outlet port are formed; and a water turbine cover (113) configured to block the tidal current leaked outside the bent wings (104). While the bent wings (104) pass through the water turbine housing (114) with the tidal current, potential energy is converted into rotational energy. When the bent wings pass through the water outlet port-side water turbine housing (114), sound pressure generated behind the bent wings (103) weakens to minimize resistance to rolling, thereby improving energy conversion efficiency even with a low head, enabling double-current power generation with rotation in one direction even if the tidal current passes through in any direction, and maximizing depth of water. |
