The invention provides a vertical axis three-streamline automatic opening and closing water turbine. The water turbine comprises a main shaft, a hub, a blade rotating shaft, a blade set and a limitingdevice. The blade set is provided with three streamline characteristics at the same time: (1) when the blade set is closed, the whole outer contour of the blade set forms a symmetrical streamline form; (2) the cross sections of upper and lower blades of the blade set form wing forms; and (3) the longitudinal sections of the upper and lower blades of the blade set form upwarped streamline forms, so that the three-streamline characteristics of the automatic opening and closing water turbine are formed. The water turbine uses the unique blade structure and rotary limiting structure for automatically opening and closing the blade set under the water current effect and forming acting force between the opened and closed symmetrical streamline blades to push an impeller to rotate.
