FIELD: fire-fighting equipment.
SUBSTANCE: invention relates to fire-fighting equipment, to manual and stationary devices for generation of air-mechanical hybrid foam of medium expansion (MEF) and sprayed water (SW) and can be used in the manufacture of fire-fighting equipment used in extinguishing various forest, emergency transport, emergency industrial and other large-scale fires. In installation of combined fire extinguishing of air-mechanical hybrid MEF or SW, containing housing (H), installed inside H mesh cassette (MC) forming air-mechanical MEF or SW, low expansion foam (LEF) or SW foam barrel and means for supplying foamer solution (FS) or water (W) to the MC and into the barrel, H is made with semi-circular side and mating flat top and bottom surfaces, on which on the side of MEF or SW outlet from H there is an annular projection concave inside H surface, and on the side of the FS or W supply means to the MC there is an annular projection which is convex to the outside of the H surface, MC is installed in H on the FS or W supply side with a stop in the annular projection concave inside H and is made of coaxially installed with interference one inside the other inner rim, containing annular cage with through hole to accommodate barrel of LEF or SW, intermediate rim, outer rim and two located with a gap relative to each other, one of which is fixed by edges in gap between mating side surfaces of inner and intermediate rims, and the other mesh is fixed by its edges in the gap between the mating side surfaces of the intermediate and outer rims, wherein in said cage in said meshes holes are made and edges of meshes near cage through hole are fixed by means of annular washers fastened to cage, and barrel of LEF or SW is placed in the through hole of the cage in the MC and is connected to the FS or W supply means.
EFFECT: increasing the efficiency of extinguishing emergency transport, forest, industrial and other fires.
