METHOD OF ACCIDENT RESCUE OPERATIONS AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2015 - IPC A62B1/00 F04B9/14 

FIELD: rescue operations.

SUBSTANCE: method comprises displacing the liquid up by the body immersed in it under the influence of its gravity and returned to the initial upper position by gravity of liquid displaced by it, acting on the lever that raises the drowned body upwards, and also displacement of liquid between the well tanks in the siphon tubes. According to the invention the liquid is pushed from the housing both under the action of gravity of the immersed body and the gravity of the storage container mounted on it with the displaced liquid stored in it, the displaced liquid is first used for additional loading of the body immersed in the liquid, and after reaching the limit depth of immersion of the drowned body the load of the displaced water is removed from it and the long lever is loaded with it, that lifts the drowned body at a distance from the bearing point of the lever, corresponding to compliance to the energy conservation principle on the lever, which is expressed in equation of moments of forces acting on the lever of the opposite direction relating to the bearing point of the lever.

EFFECT: device consisting of a housing, an immersed body, and the means for its reciprocating motion enables to remove water from flooded sites due to gravity of the immersed body and the lifted water and thus provides resource saving.
