HYDRAULIC MACHINE Russian patent published in 2004 - IPC

FIELD: power engineering.

SUBSTANCE: proposed hydraulic machine is designed for converting head of water into mechanical and electric energy. Proposed multistory hydraulic machine has skeleton firmly coupled with foundation, dam and piers on upper platforms of which load-bearing frame is encased in concrete to which skeleton of hydraulic machine is connected by its upper part. Load-bearing frame carries housing with bearings into which cylindrical shaft is fitted on which main and actuating eccentric connecting rods are secured by separate disks-eccentrics. Skeletons of chambers made in form of vertical shaft hermetically divided in storeys by covers are secured on base of hydraulic machine skeleton. Each said chamber accommodates working chamber in which square-section piston is installed which divides inner space of working chamber into underpiston and overpiston spaces. All pistons at all storeys are interconnected by rods. Upper end of upper rod is hinge-connected to common axle of narrowed power walls of main eccentric connecting rod. Side of hydraulic machine skeleton from side of upper pond of dam is called delivery side, and opposite side of skeleton from side of lower pond is called suction side. Drum-type distributors are secured at levels of all storeys of hydraulic machine on skeleton from side of upper and lower ponds. Distributors are interconnected and are set into reciprocation and rotation by chain control system of drive provided with actuating eccentric connecting rod mounted on one common cylindrical shaft with main eccentric connecting rod. Under action of pressure differential, pistons move to lower negative pressure side, and rectilinear translational movement of piston is converted by main connecting rod into rotation of cylindrical shaft, and generator connected to shaft generates electric energy.

EFFECT: increased power output, reduced consumption of water.
