WATER LIFTING METHOD, AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2013 - IPC F04F1/08 

FIELD: engines and pumps.

SUBSTANCE: water lifting method involves an aeration operation of liquid being lifted upwards due to air ejection from atmosphere with a jet of the same liquid leaving the well through a branch pipe to water surface under action of excess pressure in the well, which is created with weight of the water lifting device, a ballast and axial force. As ballast, water is used, which is lifted out of the well, and axial force on the water lifting device housing is created with weight of an operator. Return of the water lifting device to initial position is performed due to Archimedes buoyancy force acting on the hollow housing of the water lifting device at its submersion into water. The water lifting device includes a hollow tight housing fixed on a water lifting pipe, in which a water outlet branch pipe of the well and a mixing chamber are arranged. The mixing chamber is connected through an air tube to atmosphere. In upper part of the lifting pipe the provision is made for a water collector with its unloading devices, into which air and water lifting pipes are directed. There are hydraulic sealing devices of an annular gap between walls of the housing and walls of a casing pipe of the well. At upper point of the lifting pipe there located is a pressure roller, through which a rope is hitched. One end of rope is fixed, and free end of rope is equipped with a step for arrangement of the operator.

EFFECT: invention allows reducing labour intensity of water lifting out of the well.
