The invention relates to a universal fully-effective generating power machine belonging to generating power equipment which can fully and effectively convert conventional energy resources such as water energy, steam energy and the like and new energy resources such as wind energy, steam energy formed by solar heating, tidal water energy and the like into rotating mechanical energy. The machine mainly comprises one or a plurality of jet orifices, a regulating mechanism of the jet orifices, one or a plurality of universal fully-effective rotating wheels, a speed regulator and the like, wherein, the universal fully-effective rotating wheels correspond to the jet orifices and are arranged on a main shaft. The machine can fully develop and utilize water energy, steam energy and wind energy of all types, can fully and effectively convert the utilized water energy, steam energy and wind energy into rotating mechanical energy, can fully replace all current water turbines, steam turbines and wind turbines, and has the advantages of simple structure, reliable performance, low manufacturing cost and easy implementation. Thus, the universal fully-effective generating power machine can replace equipment of hydraulic, thermal and wind power generation industries, and can promote rapid development of new energy resource generating industries such as hydraulic fully-effective power generation, hydraulic wind power generation, solar steam power generation and the like to become main energy source power generating modes.
