WATER PUMPING SYSTEM OF A FLOATING WHEELED VEHICLE Russian patent published in 2023 - IPC B63B13/00 F04D13/02 

FIELD: floating wheeled vehicles.

SUBSTANCE: water pumping system of a floating wheeled vehicle comprises a suction cavity of a water jet, front and rear pumping valves with chutes and hydraulic drives, additionally equipped with an electronic control unit (ECU), an electric motor for controlling a bypass valve, two electromagnetic relays for controlling a hydraulic distributor, a rotation sensor for a water jet drive , an electric pump rotor rotation sensor, contactors installed two by two on the front and rear evacuation valves and on the bypass valve and providing a signal to the computer for the closed or open state of the corresponding valves. The ECU is electrically connected to the rotation sensor of the jet propulsion drive, the rotation sensor of the electric pump rotor, the evacuation electric pump, the bypass valve control motor, the electromagnetic relays for controlling the hydraulic distributor, valve contactors, the switch and indicator lamp of the evacuation electric pump, the switches for controlling the opening and closure of the evacuation valves, and the bypass valve and their indicator lights. The electrical connection of the sensors of the signalling devices indicating the presence of water in the housing with signal lamps is carried out through amplifiers and the computer.

EFFECT: increasing the level of automation of the process of pumping water entering the machine body, mobility, controllability and safety, and ensuring the completeness of pumping water from the body when the floating wheeled vehicle moves afloat.
