FLOATING TRANSPORT PLATFORM Russian patent published in 2019 - IPC B60F3/00 

FIELD: machine building.

SUBSTANCE: invention relates to transport platforms of cargo, passenger, industrial, military and agricultural machines adapted for independent movement on land (ground) and on water. Transport platform adapted for installation of functional equipment on it comprises waterproof housing, on-board electric power source made in form of internal combustion engine with connected to it generator and/or accumulator battery, as well as water and ground propellers having independent electromechanical drives. Water drive engine is made in the form of water chutes or impellers driven by electric motors of mainly annular type, having external stator and hollow rotor, inside which one or several impellers (screws, augers etc.) are installed. These motors can be counter-rotor, having external stator and two annular hollow half-rotors, mechanically connected with coaxial counter-rotors installed inside these semi-rotors. Stator can be partitioned and made with different alternation of phases in its sectors, which provides anti-rotation of the semi-rotors. Each screw (auger) attached to rotor or semi-rotor can be made without central hub and without central shaft. If a multi-phase AC generator is installed on the platform, asynchronous motors of the water drive engine can be controlled by direct connection to the generator with change of the phase alternation order. System of electrical equipment of platform implements control of its functional equipment and drives of land and water drive, as well as protection of its components from damages and emergency modes of operation.

EFFECT: invention simplifies design, improves reliability and speed of floating transport platform on water.
