Abstract: PURPOSE: A tidal current generator is provided to install a tidal induction plate, which is extended from one side of a guide vane to a direction in which a tidal current flows, inside a duct, thereby preventing the tidal current from being stagnated by the guide vane. CONSTITUTION: A tidal current generator comprises a duct(100), a rotary shaft(200), plural blades(300), and a guide vane(400). The duct forms a water path for the inflow and the outflow of a tidal current. The rotary shaft is installed inside the duct to be vertical to the tidal current direction. The blades are radially installed at the external surface of the rotary shaft, and are rotated by the tidal current which flows inside the duct. The guide vane is formed to protrude inside the duct in order to surround the blades which receive an external force in an opposite direction to the rotary direction by the tidal current which flows inside the duct. A tidal induction plate, extended to a direction in which the tidal current flows and is coupled to the internal surface of the duct, is installed at one end of the guide vane. Two guide vanes are respectively installed at the left and right side of the rotary shaft to be mutually symmetric in a diagonal direction.

Abstract: PURPOSE: A turbine for tidal current generation is provided to prevent the lift force deterioration of a blade due to flow separation, thereby increasing the rotation efficiency of the blade for improving power generation efficiency. CONSTITUTION: A turbine for tidal current generation comprises a hub(100), plural blades(200), a generator assembly(300), and plural guides(210). The hub is rotatably installed under sea surface. The plural blades are radially installed at the external surface of the hub. The generator assembly is coupled to the hub, and receives the rotary force of the hub in order to generate electric energy. The plural guides are formed to protrude on the surfaces of the blades, and block the flow of a radially tidal current which occurs along the longitudinal surfaces of the blades. The guides are formed to protrude on the front ends of the blades for being connected with the hub and the blades. The guides protrude to be inclined to the longitudinal direction of the blades at certain angles(α).
