FIELD: power industry.
SUBSTANCE: invention relates to flow energy converters located along it and taking hydraulic energy at the distance determined by the converter length. A mini hydro-electric power plant includes a screw consisting of a cylinder with blades on its surface. The cylinder is connected to the generator and located along a water flow. The blades are made in the form of several pipes uniformly located along the cylinder surface along a helicoid line. A confuser with maximum cone diameter equal to the cylinder diameter and a diffuser the minimum diameter of which is equal to a sum of the cylinder diameter and two diameters of pipes at their inlet are connected to the cylinder. Outlet ends of the pipes are provided with tips installed at a tangent to cylindrical surface.
EFFECT: invention is aimed at increase of efficiency and specific output power owing to increasing the effect of obtaining higher pressure from a moving flow and simultaneous use of a jet component of the flow.
