Water intake facilities from mountain rivers

摘要

The invention relates to hydraulic construction, namely, to the water intakes designed for water intake from mountain rivers transporting sediment, in hydropower, irrigation systems and water systems. The apparatus consists of placing on the shore supply channel water intake tip exhaust channel equipped with a flow regulator placed in the mainstream of retaining structures, river passage having avtoregulyator limit level flush holes gate catastrophic weir relief valve, relief weir the upstream and water receiving chamber separated from the feed channel broken in terms nanosozaschitnym threshold as a vertical wall with a compartment projecting towards the river about summer and separating bull. Comb nanosozaschitnogo threshold broken plan made horizontal and at the start threshold nanosozaschitnogo taken Water inlet overlapping flat gate. After the ruptured in terms nanosozaschitnogo threshold is arranged an additional washing with a washing path opening dual overlapping gate and before washing otvertishsya performed bottom insert surface with a reverse bias. The relief of the upstream weir is formed as a broken threshold in terms of a terminal section perpendicular webs avtoregulyator limit. The utility model provides increased reliability required amount of water intake, increased conveying capacity transit flow of water and thus decrease seizure sediment in water intake chamber and a discharge channel.
