Open-type gravity water turbine equipped with shielding plate, screen and water turbine for power generation

摘要

An open gravity-type water turbine provided with a shielding plate, a screen, and a water turbine for power generation is provided. An open gravity-type water turbine is mounted in a water channel so as to be swingable on a support shaft at the upper part of the water channel, and shields the water in the water channel to create a water flow from the upper part toward the lower part. 14, a linear screen 13 attached to the support shaft at the upper part of the waterway, and a descending rake 15 installed so as to move up and down the front surface of the screen, On the downstream side, a power generation turbine attached to a support shaft at the upper part of the water channel via a support arm 22 is provided. The shielding plate, the screen, and the water turbine for power generation are swung up, and the dust stored in the pocket between the screen and the shielding plate is caused to flow down from the lower part. When the waterways increased due to heavy rain or typhoon, the screen and power generation turbine were lifted on the surface of the water to ensure safety during floods. [Selection] Figure 1
