The present invention relates to a movable blade power generating module for a vertical shaft type wind power generator, wherein the movable blades are connected by two blade plates in a manner of movable pivot connection, the movable pivot connection constructs and controls opening and closing angle of the two blade plates, and the movable blade is provided with a windward side and a leeside. When wind reaches the windward side, the movable blades are open; and when the wind reaches the leeside, the movable blades are closed; a group of power generating modules comprising at least one permanent magnet and one induction coil are equipped at the opening and closing moving end of the two blade plates and on the moving path formed by the opening and closing motion. Through the continuous rotation of a wind wheel under the action of the wind, the mechanical energy generated by the opening and closing motion of the movable blades is converted into electric energy, thereby increasing the power generation efficiency of the wind power generator.
