Filed: 1989-07-07
Abstract: PURPOSE:To efficiently take out the output of a water wheel by standing upright a casing enclosing a runner connected to a water wheel shaft and guiding water, and providing a draft tube having draft effect which is connected to the casing and inserted into a tailrace. CONSTITUTION:When a gate 19 is opened to run water into the upper water passage 12 of a generator chamber 16, the water falls down in the casing 17 of a cross flow water wheel 10 and vertically enters into a runner 3. Thus, the runner 3 is rotated to generate a power in a water wheel shaft 1, and this power is transmitted through transmitting means 20-22 to a generator 11, wherein power generation is conducted. At this time, a draft tube 18 has a head of a static draft height of water sucked from the water surface of a tailrace by the draft effect. Thus, the output of the cross flow water wheel can be efficiently taken out even at an ultra-low head.
