METHOD FOR FOAM FIRE EXTINGUISHING AT SEA OBJECTS AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2019 - IPC A62C3/10 A62C29/00 B63G8/00 

FIELD: fire safety.

SUBSTANCE: invention relates to fire-fighting equipment and is intended for use in underwater position of self-contained unmanned underwater vehicle during foam fire extinguishing at sea objects. Self-contained pilotless unmanned underwater vehicle for foam extinguishing of fire on sea objects is made in form of floating ship and comprises ship hull, in which are installed propulsion plant, self-contained power source, instruments of control, communication, navigation, detection and classification of underwater and surface objects, device for delivery of liquid fire-extinguishing agent on floating ship to fire center, crankshaft for supplying the fire extinguishing agent flow to the device for its formation and guidance thereof to the fire center in the above-water position of the above device. Floating vessel is made in the form of self-contained pilotless unmanned underwater vehicle, on which there is a device for delivery of liquid fire extinguishing agent on floating ship to fire center. Crank-type elevator for supply of liquid fire-extinguishing agent into fire source from underwater to above-water position is mounted rigidly outside on upper shell of self-contained pilotless unmanned underwater vehicle. Fire extinguishing agent flow formation and guidance device is made in the form of a foam generator. For foam fire extinguishing at sea objects, controlled area is explored by available observation means in case of fire, delivery of a fire-extinguishing facility on a floating ship and its supply to a cranked elevator, guidance of a fire-extinguishing agent flow to the fire center and extinguishing of the named center of fire with available fire extinguishing means in a surface position.

EFFECT: simplified use of the device in operation.
