Title:
HYDROELECTRIC POWER GENERATING DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/190136
Kind Code:
A1
Abstract:
A hydroelectric power generating device according to one mode of embodiment of the present invention is provided with a water turbine (1), an electricity generator unit (2) and a drive unit (3). The water turbine (1) includes a first shaft (11) and a blade (12). The blade (12) is attached to the first shaft (11). The blade (12) is disposed in a flow path along which water flows, and by means of the water, causes the first shaft (11) to rotate about a central axis (11a) of the first shaft (11). The electricity generator unit (2) includes an electricity generator (23). The electricity generator (23) includes a second shaft (23b) and generates electricity as a result of rotation transmitted from the first shaft (11) to the second shaft (23b). The drive unit (3) causes the first shaft (11) to rotate relative to the electricity generator (23) in a plane containing the direction in which the first shaft (11) extends.
