FIRE-EXTINGUISHING DEVICE Russian patent published in 2004 - IPC

FIELD: environment protection, particularly for extinguishing fires by reflected waves of pin-point explosions.

SUBSTANCE: device comprises independent frame having adjustable cantilever members and point or constricted explosive charge arranged on cantilever members in predetermined focal point F. Device also includes reflecting screen with screen focus in F point. Reflecting screen is made as a pack of resilient multi-layer rectangular plates connected to frame and resiliently bent by means of resilient guide supports with longitudinal loads applying along characteristic reflecting screen dimension. To provide desirable strength of reflecting screen possible strength stresses appeared as a result of explosion wave are estimated and appropriate materials for screen plate layers production, number of layers, layer thickness, rigidity and mutual arrangement are selected.

EFFECT: increased strength of reflecting screen, improved efficiency.
