KOCHETOV EXPLOSION PROOF PANEL FOR EXPLOSIVE OBJECTS Russian patent published in 2016 - IPC E04B1/92 

FIELD: blasting.

SUBSTANCE: invention relates to protective devices used in explosive and radioactive facilities, such as easily detachable panels and roofs, explosion proof enclosures and screens, designed prevent emergency situation (ES). Explosion proof panel comprises metallic armoured carcass with metallic armoured lining and lead filler, It has four fixed supporting pipes fitted at its ends. In coating of explosive object are rigidly embedded four bearing rods, which are telescopically inserted into fixed branch pipe-support of panel. Filler is in form of an air-lead disperse system, wherein lead is in form of chips, and bearing rods are made flexible. Support sheets are successively fitted with elastically damping and fast-decomposing, single-action elements. Fast-decomposing element is made, for example, in form of a bushing enclosing a support rod and is made of laminated glass or porcelain or ceramics, or composite material. Elastically damping element is in form of a sleeve made from elastomer, for example polyurethane, or spring filled with polyurethane. At least one fast-decomposing element is made with an alarm system in form of a sleeve, for example, made from laminated glass, or porcelain, and female support rod, and having in middle part a built-in safety indicator in form of two truncated conical surfaces, tops of which are directed towards each other. On one of surfaces is fixed a sensor responding to destruction, for example resistive strain gauge, output of which is connected with an amplifier of a signal supplied to input of alarm system. To increase reliability of operation of explosion proof panel, in particular for its displacement on a given vertical trajectory upwards, each rod is made with a reinforced base located in coating of explosive object.

EFFECT: technical result consists in improvement of reliability of explosion-proof devices at emergency explosion on and providing return of said structures into initial position after explosion, as well as alerting personnel on emergencies.
