HYDRAULIC UNIT FOR CONVERTING KINETIC ENERGY OF WATER FLOW INTO ELECTRIC ENERGY Russian patent published in 2005 - IPC

FIELD: hydraulic engineering.

SUBSTANCE: device is designed for converting kinetic energy of small and medium rivers into elastic energy. Proposed hydraulic unit contains hydraulic turbine installed on frame with bearings on its shaft, generator mechanically coupled with hydraulic turbine, stream shaper and device in form of plates to protect hydraulic unit from floating debris. Hydraulic unit has intermediate vertically and horizontally installed shafts with bearings interconnected by conical gears. Vertical shaft is arranged in well built near bank and communicating with river by channel made under level of maximum possible thickness of ice cover. Part of horizontal shaft connected with hydraulic turbine is arranged in said channel. Upper end of vertical shaft is connected with generator through ground horizontal shaft and step-up reduction unit. Stream shaper is made in form of flaps installed on shaft for turning to direct water stream of river to its central part between which turnable gate is installed for contacting with one of flaps to direct water stream to right-hand or left-hand side of hydraulic turbine.

EFFECT: provision of reliable operation all year round.
