PROBLEM TO BE SOLVED: To provide a practical small-type hydraulic generating equipment capable of generating electricity efficiently in less-expensive cost under utilization of a slight step at a small river.SOLUTION: This invention relates to induction ducts 5 having a structure in which they are applied over a step upstream segment and a step downstream segment under utilization of a slight step at a small river, duct spoons 17 for efficiently transmitting flowing water energy to water turbine runners 16 are installed at a narrow outlet of the step downstream segment, approximate lower half part of the water turbine runners 16 is immersed in the duct spoons 17 so as to rotate the water turbine runners 16. Parallel-cross bridge tables 8 having a function capable of optionally adjusting heights of the water turbine runners 16 and the induction ducts 5 in response to a water level of the river and raising channels are arranged between water intake port bottom parts of the induction ducts 5 and the upstream bottom parts of the river step in preparation for the lowering of the water level of the river in a dry season, the water level of the river upstream is raised to utilize a head drop up to the water turbine effectively. In addition, in regard to flowing dusts at the river, a dust removing screen 18 is installed at the upstream side of the induction ducts. |
