CONTROLLABLE PROJECTED AREA TIDAL CURRENT POWER TURBINE, MANUFACTURING METHOD OF SAME AND TIDAL CURRENT POWER METHOD IN USING SAME

摘要

The present invention relates to a variable area tidal current power turbine, a manufacturing method thereof, and a tidal current power method using the same. The purpose is to provide a variable area tidal current power turbine, a manufacturing method thereof, and a tidal current power method using the same capable of producing power at a fluid velocity lower than predetermined intensity by maximizing forward direction rotation force by controlling a distance between an area of each blade and a central shaft. For this, the variable area tidal current power turbine includes a central member, a top plate covering the central member by being installed on the top of the central member and having a top track forming an eccentricity track for the central member formed on its bottom, a bottom track covering the central member by being installed on the bottom of the central member and having a bottom track forming an eccentricity track for the central member formed on its top, and a plurality of blade parts installed around the central member. The blade parts change its area as a distance between the central member and the eccentricity track and rotate the central member while rotating around the eccentricity track.
