FIELD: water supply; intended for self- washout of water-intake buckets and prevention of deposition of drifts in the bucket in case of variation of water stream flow conditions and underflooding (for instance, by water storage). SUBSTANCE: the upstream and downstream walls of the self-washing bucket are made in the form of separate modules representing hollow box-type constructions, in which hollow overflow walls move in the vertical direction; for adjusting the buoyancy of walls they are provided with flooding and compressed-air blow-off systems. EFFECT: provision of self-washout of water-intake bucket at variation of flow conditions and in flooding conditions. 3 dwg |
