WATER LIFTING METHOD AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2011 - IPC F04B1/00 F04B9/14 

FIELD: power industry.

SUBSTANCE: water lifting method involves separation operations of restricted water volume in the reservoir by means of housing, displacement of water from the housing to consumer by submerging the water lifting device into the housing. Water is displaced along the gap between housing and water lifting device body. At that, water volume extracted with the housing shall be more than volume of the specified gap, and volume weight of water lifting device body shall be more than volume weight of the liquid displaced to consumer. Device for method's implementation includes housing, water lifting device body arranged in the housing with possibility of axial movement and fixed on short end of the lever supported on the point offset from lever symmetry axis.

EFFECT: method and device allow water displacement with high efficiency of up to one cubic metre per cycle and more; energy consumptions for water displacement are reduced since operating stroke is performed owing to gravity force of water lifting device body, and energy consumptions are reduced in idle mode owing to using water buoyancy force.
