METHOD AND DEVICES FOR INCREASING DEEP WATER, PASSABILITY, EFFICIENCY, UNIVERSALITY OF VEHICLES, EFFICIENCY OF WORKS ON GROUND Russian patent published in 2023 - IPC B63G8/14 G05D16/08 B63B1/02 B63G8/24 G05D16/06 

FIELD: car industry.

SUBSTANCE: solution relates to a method for changing a submersion depth in a water environment of vehicles having engines, movable parts, electrical, oil, pneumo-hydraulic, ballast systems. The method consists in that, as working medium substance of ballast and pneumo-hydraulic systems, substance is used, which has a critical temperature above a water temperature at a sea depth; the specified working medium substance is transferred to a phase state: gaseous, liquid, or supercritical, depending on the sea depth and a required type of vehicle buoyancy. In systems on sealing devices of movable parts, the minimum pressure drop of lubricants is created before overboard pressure; in oil systems, working medium pressure is aligned with external overboard pressure, using membranes, and the minimum pressure drop relatively to external overboard pressure is created with oil pumps, or the mentioned drop is created with pressure of a spring and overboard water through washers and membranes on oil stocks in oil tanks; in electrical systems, electrolytes of liquid batteries and overboard water are separated with membrane.

EFFECT: provision of modernization of submarines and bathyscaphes, creation of deep-water construction and mining equipment, rescue and research stations, bulldozers for restoration of washed-out beaches, deepening of fairways and riverbeds, robots for lifting sunken ships, excavators capable of efficiently operating even on the seabed of the Mariana Trench.
