METHOD OF EXTINGUISHING FIRES USING ROBOTIC FIRE EXTINGUISHING INSTALLATIONS Russian patent published in 2023 - IPC A62C37/09 A62C35/00 A62C2/24 

FIELD: firefighting.

SUBSTANCE: method of extinguishing fires using robotic fire extinguishing installations (FEI) includes detecting and determining the coordinates of the source of fire in the protected area, extinguishing the source of fire over the area by line scanning for a set time. Fire robots form jets of water and foam and deliver them to the fire using the FEI control device. Pointing the barrels at the source of fire is controlled by the ballistic data of the jet depending on the angle of inclination and pressure. The fire extinguishing parameters are optimized on the burning surface itself using a control unit for extinguishing parameters containing data on the set flow rate Q_y for the fire robot, the calculated area S_ca, the effective range R_e, the specific fire load of the protected premises g, time data extinguishing t_t of model fires depending on the fire load G_mf. The parameter for the established flow rate FEI Q_y is optimized according to the condition of necessity and sufficiency of flow. The average irrigation intensity i_av is maintained greater than or equal to the standard irrigation intensity i_n: i_av>i_n over the entire area of the protected object. The average irrigation intensity i_av is determined from the calculated irrigation area S_ca located at the most distant distance R_e of the protected object, which includes the surface area of the model fire S_mf depending on the group of premises according to fire hazard and the area of the pointing error d_S: S_ca = S_mf + d_S. The supply of fire extinguishing agent (FEA) to the irrigated area S_ia is controlled, which includes the fire area S_ca and the pointing error area d_S: S_ia =S_ca +d_S, so that the supply of fire extinguishing agent does not exceed the design area S_ca: S_ia < S_ca.

EFFECT: increasing the efficiency of extinguishing by optimizing the extinguishing parameters.
