Rotary-driven power generation device

A rotary-driven power generation device configured by:

• connecting a rotational drive source with high torque and low rotation speed specification to a vertical central rotational shaft;
• providing a cylindrical body, which is concentrically fixed to the central rotating shaft, on an elastically deformable rotary disk attached orthogonal to the central rotational shaft;
• attaching a plurality of power generation motors to a low plate at equal intervals relative to a center of the rotary disk and with power generation motor shafts directed to a radial direction;
• and
• bringing a wheel fixed on a tip of the power generation motor shaft into contact with an annular wheel-running track on a cylindrical body, wherein:
• when starting the rotational drive source, rotational force required to start the power generation motors is ensured by the frictional contact of the wheel with respect to the wheel-running track;
• and
• during steady rotation after starting the rotational drive source, driving force of the rotational drive source is reduced by rotational inertia of the rotary disk while the rotary disk is deformed into a dish shape by centrifugal force acting on a center of gravity of the rotary disk in order to reduce contact friction resistance caused by the wheel, the wheel-running track, and pressing force, which are about to separate from each other, and to reduce a load on the rotational drive source, so that multiple electric power is efficiently and independently output from the respective power generation motors.

A rotary-driven power generation device configured by:

• connecting a rotational drive source with high torque and low rotation speed specification to a vertical central rotational shaft;
• forming an annular fan blade between a central area and an outer peripheral area of a rotary disk attached orthogonal to the central rotational shaft,
• providing an annular wheel-running track on an outer periphery of the rotary disk so that the wheel-running track is concentric with the central rotational shaft,
• attaching a plurality of power generation motors to fixed-side members at equal intervals relative to a center of the rotary disk and with power generation motor shafts directed to a radial direction;
• and
• bringing a wheel fixed on a tip of the power generation motor shaft into frictional contact with the wheel-running track, wherein:
• during rotation of the rotary disk after starting the rotational drive source, driving force of the rotational drive source is reduced by rotational inertia of the rotary disk and multiple electric power is efficiently and independently output from power generation motor output lines of the respective power generation motors while forcibly cooling heated portions by air blown by the fan blade as the rotary disk rotates.
