KOCHETOV EXPLOSION-PROOF PANEL Russian patent published in 2017 - IPC E04B1/92 

FIELD: fire safety.

SUBSTANCE: explosion-proof panel comprises a metal armoured frame with metal armoured plating and lead filler, and has four fixed bearing pipes at the butts, and four support rods which are telescopically inserted in the fixed bearing pipes of the panel are tightly sealed in the explosive object coating. Filler is made in the form of dispersed air-lead system. Lead is shaped in the form of crumbs, and the support rods are made resilient, and elastic-damping and quickly destructing disposable elements are sequentially mounted to support plates, wherein quickly destructing element is made, for example, in the form of a sleeve covering the supporting rod and made of glass type "triplex", or porcelain, or ceramic, or composite material, and elastic-damping element is designed as a sleeve of elastomer, such as polyurethane, or a polyurethane-filled spring. At least one quickly destructing element is equipped with alarm system designed as a sleeve, for example, made of glass type "triplex", or porcelain, covering the support rod and having an embedded security indicator in middle portion in the form of two truncated conical surfaces, the tops of which are directed towards each other. There is a sensor, for example, a strain gaufe, fixed on one of the surfaces, responsive to a destruction, output of which is connected to amplifier of signal incoming to input of the emergency alert system.

EFFECT: increased reliability of operation of explosion-proof devices in case of emergency explosion at the facility, and the return of these structures to original position after the explosion, emergency personnel notification.
