Abstract

PURPOSE:To save a series of public work, which necessitates an enormous building cost remarkably and permit to build the miniature hydraulic power plant of low power generating cost by a method wherein the head of flow speed regulating dam or the like of the river is utilized and the structural body of the power plant is buried below the bed of the river to generate electric power. CONSTITUTION:A water intake pit 1 is installed at the upstream side of the dam 3 of the river and a water discharging pit 2 is installed at the downstream side thereof to catch the energy of head H at the lower position of the bed of river and generate electric power by a tube runner water turbine generator 8. Coarse dust, which flows into the water intake pit 1, is screened by a rough mesh screen 4 while middle and small duct is screened by a fine mesh screen 5 before flowing into a water intake tube 6. The flow of water, whose dust is screened, drives the tubular water turbine generator 8 or the like through the water intake tube 6 in the water intake pit 1 and generates electric power, thereafter, is discharged to the downstream of the dam from the water discharging pit 2. According to this method, the miniature hydraulic power plant of low power generating cost may be built.
