Title:
POWER GENERATION DEVICE AND POWER GENERATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2021/124588
Kind Code:
A1
Abstract:
Provided are a power generation device and a power generation system, which can sustain constantly stable rotation and use a rotary body that does not cause accidents that would adversely affect people or nature. This power generation device transmits the rotation of a rotary body 1 to a shaft of a power generator and uses the rotary body as a power generation source for power generation. The power generation device comprises a rotation drive device 6 in which the rotary body is disposed in a plurality at prescribed intervals. The rotary body, which is pivotably supported on a rotary shaft 6c extending across a support body 6a and uses the weight of a solid body 5, includes: a central rotary body 2b into which the rotary shaft is inserted and which transmits rotation in only one direction to the rotary shaft; a rotary frame 2 into which the rotary shaft is inserted and which is fixed to the central rotary body; fixed pulleys 31, 32 that are fixed to both end sections of the rotary frame; a solid body movement means that includes a wire 4b for moving the solid body and an uptake drum 4a for taking up the wire, the uptake drum 4a being driven by a power-requiring motor 4; and the solid body that moves between the fixed pulleys and has a prescribed weight. A moving pulley 5a is attached to one surface of the solid body and a traveling wheel 5b is attached to another surface. The solid body movement means is further provided with a travel guide rail 4c for movement of the solid body, which is directly coupled so as to pass between both end sections of the rotary frame in the vicinity of the rotary shaft at the center, with the traveling wheel of the solid body capable of moving by running along the travel guide rail. An action is repeated in which the rotary frame rotates when the solid body at an end section of the rotary frame located on the lower side due to self-weight is hoisted by uptake of the wire by the uptake drum and is shifted to the other end section located on the upper side, and the upper-side end section to which the solid body shifted then moves downward due to the weight of the solid body. The rotary body is inclined at a prescribed angle before the rotating action or when rotation is interrupted.
