PURPOSE: A windmill having a secondary rotating unit for a main blade is provided to efficiently produce electricity since fluid from a tank moves from a suction pipe to a discharge pipe by the rotation of a secondary blade to rotate a blade and thus the torque of a first vertical shaft making contact with a buoyant member increases. CONSTITUTION: A windmill having a secondary rotating unit for a main blade comprises a tank(10), fluid(11), a buoyant member(20), a blade unit(30), a first vertical shaft(40) and a vertical blade(42). This windmill further comprises a horizontal rotary plate(50), a generator(60), a second vertical shaft(70) and a secondary blade(72). This windmill further comprises a fan(82), a suction pipe(90) and a discharge pipe(91). The tank is loaded on a frame(1). The fluid is stored in the tank. The buoyant member floats on the fluid. The blade unit is formed on the upper part of the buoyant member. The vertical blade forms circumscription with the first vertical shaft. The generator is connected to the horizontal rotary plate operatively. |
