Abstract

The present invention relates to a vertical rotating shaft type rotational force generator that is capable of allowing a plurality of blades rotating around blade rotation shafts and simultaneously revolving around blade revolution shafts, when receiving a pressure caused by the flow of a fluid, to provide the rotational forces generated therefrom for the blade revolution shafts. Even if no separate left and right direction control power device exists, the blade revolution shafts automatically move toward positions where rotational forces generated therein are maximized, and rotation phase angles and revolution phase angles of a plurality of blades effectively interlock with each other, so that even though the blades are located at any revolution phases, they provide the rotational forces produced to the maximum according to revolution phase always in the same rotation direction for the blade revolution shafts. Further, in the case where the flow velocity and pressure of a fluid are excessively increased due to strong winds or floods, even if no separate upward and downward direction control power device exists, the blade revolution shafts are automatically tilted in a direction where the overturning moment generated in the support and foundation of the rotational force generator and the rotating torque generated in the blade revolution shafts of blades are drastically decreased, so that the rotational force generator is prevented from turning over or collapsing due to the excessive dynamic load of the fluid, and further, the rotational force generator including each blade revolution shaft is prevented from being damaged due to excessive rotational speeds, thereby optimizing the efficiency and safety thereof.
