APPARATUS FOR EXTINGUISHING BOTTOM FOREST FIRE AND LAYING FOAM SUPPORT STRIPS FOR COUNTER FIRE Russian patent published in 2020 - IPC A62C3/02 A62C5/02 

FIELD: fire safety.

SUBSTANCE: invention relates to forest fire control and production of preventive burning out of forest combustible materials, namely to portable motorized devices for fire extinguishing of forest fire of low and medium intensity, as well as laying foam support strips in order to produce annealing from them during fire extinguishing with high intensity. Device for extinguishing bottom forest fire and laying foam support strips for annealing comprises kneading tank for foam-forming liquid, fan with drive from internal combustion engine, air barrel fixed on fan blower branch pipe and equipped on end with foam generator, flexible pipeline for supply of liquid from the reservoir into the air shaft, inside which there is a regulator of air flow power and coaxially fixed pipeline, hydraulically connected to the flexible pipeline for liquid supply from the reservoir. Device is additionally equipped with a liquid pump kinematically connected to the engine shaft, wherein the pump is hydraulically connected to the foaming fluid container and with the flexible pipeline for feeding liquid into the air shaft, and inside the air shaft there is a segment gate valve with two-position manual drive, designed to control air flow power when producing foam of low or high multiplicity.

EFFECT: technical result consists in improvement of performance of device for extinguishing of forest fire and laying foam support strips for annealing due to possibility of change of foam rate and supplying the foaming composition in accordance with air flow during the process of extinguishing the process, reducing water consumption and increasing the efficiency of the forest fireman.
