Title:
ROTATIONAL FORCE-GENERATING APPARATUS REVOLVING AND ROTATING ACCORDING TO FLOW OF FLUID
Document Type and Number:
WIPO Patent Application WO/2022/220481
Kind Code:
A1
Abstract:
The present invention relates to a vertical rotary shaft-type rotational force-generating apparatus in which a plurality of rotary blades that rotate about a blade rotation shaft while revolving about a blade revolution shaft provide rotational force to the blade revolution shaft when pressure is applied to the rotary blades by the flow of a fluid. The rotational force-generating apparatus having maximized energy efficiency and structural safety is characterized in that: even when there is no separate lateral direction control power device, the blade revolution shaft automatically moves to the position and in the direction in which the rotational force generated in the rotational force-generating apparatus is maximized; the rotation phase angle and the revolution phase angle of each of the rotary blades are effectively linked with each other, such that the maximum rotational force that can be generated for each of the revolution phases is provided to the blade revolution shaft in the same rotation direction regardless of what revolution phase each of the rotary blades is positioned at; and when the flow speed and flow pressure of the fluid are excessively increased by a typhoon, flood, etc., the blade revolution shaft, although lacking a separate vertical direction control power device, automatically tilts in a direction in which both the overturning moment generated in support posts and foundations of the rotational force-generating apparatus and the rotational moment generated in the blade revolution shaft of the rotary blades decrease exponentially, thus preventing the rotational force-generating apparatus from overturning due to the excessive dynamic load of the fluid, or preventing the rotational force-generating apparatus, such as the blade revolution shaft, from being destroyed by excessive rotation speed.
