FIELD: power engineering.
SUBSTANCE: bottom hydraulic power plant comprises turbines, made in the form of screws 6, installed in a river flow and lowered to its bottom, for instance, from a bridge rack 1 or from a float base, a current generator 15 and its drive. The outer circuit of each turbine represents a cylindrical shell, on the outer side with a coupling 8, for instance, of spindle type, which connects the augers 6, if there are more than one of them, into blocks that may close the entire clear section of the river, if required. Each turbine in the block or the entire block are fixed in bearings on a movable frame 3 that moves preferably in the vertical plane.
EFFECT: invention makes it possible to simplify design and to increase its reliability, development of a hydraulic power plant with submerged turbines, which may take maximum of energy potential from a river during the year.
