Abstract
The apparatus includes a water collecting plate 6 which collects water into a water inflow opening 8 while intercepting and accumulating water flowing through a waterway, and a movable gate 5 which is capable of changing flow cross-sectional area of water flow acting to the top ends of rotor blades 33 of a vertical axis turbine 3 as inflowing from the water inflow opening 8. Here, owing to changing of flow cross-sectional area with opening and closing of the movable gate 5, a flow rate can be adjusted by changing a water level at the upstream side and opening area of an orifice hole and operation of the rotor blades 33 can be stopped by blocking water passing toward the vertical axis turbine 3.
