WIPO Patent Application WO/2020/196018
Kind Code:
A1
Abstract:
A hydraulic power generation apparatus (1) is provided with: an impeller (8) which converts hydraulic power into rotary force; a power generator (10) which generates electric power by rotation of the impeller (8); and a water collecting device (22) which is installed on the upstream side of the impeller (8) and which collects water of a water channel (2) toward the impeller (8). The water collecting device (22) includes: a water collecting plate unit (23) which increases the speed of the water of the water channel (2) and guides the water to the impeller (8); and water collecting plate guides (26) for providing the water collecting plate unit (23) to the upstream side, by a predetermined distance, of the water channel (2) with respect to the impeller (8). The water collecting plate unit (23) is divided into a plurality of water collecting plates (24) in a plane (P) formed by the water flow direction (A1) and the vertical direction, and the divided water collecting plates (24) are respectively inserted into the water channel (2) along the water collecting plate guides (26).
