PROTECTIVE DEVICE FOR EXPLOSIVE OBJECTS Russian patent published in 2016 - IPC E04B1/92 

FIELD: blasting.

SUBSTANCE: invention relates to safety devices used in explosive and radioactive facilities, such as easy detachable panels and roof, blast guards and shields, excessive pressure valves. Protective device for explosive facilities, comprising a metal armored frame with armored metal plating and filler, which is made in the form of air-lead disperse system, wherein the lead is made in form of chips, and the frame has at the ends fixed branch pipes-support, and in the coating of explosive object is rigidly fixed, at least, three support rod with plates-stops in the upper part, which is telescopically inserted into fixed branch pipes-support in the metal armored frame in upper part of base rods elastic damping elements are fixed, one end of which is rigidly connected by its base with plates-stops, and the other one is arranged freely, each of the elastic damping elements is fixed by means of screws with its base, made in the form of round disk from rigid vibro-damping material of "Agat" type, on sheets-thrusts rigidly connected with rods, and the base the resilient damping element is connected to the sleeve made from elastomer with central hole PIN to pass through the sleeve has at least three holes aligned with rod, in which there are elastic elements, for example cylindrical screw Springs, upper end of which by means of fastening elements is connected with base, and bottom is in non-compressed state and protrudes beyond the sleeve bottom plane at a distance defined by the force generated with impact blast wave. End surface of sleeve connected to the base of resilient damping element is rigidly attached additional damping element made in form of at least three resilient rods, interconnected damping ring made from vibration damping material, for example, polyurethane, ring plane with rods is located above plane of armored metal frame with armored metal plating.

EFFECT: technical result-increase of reliability of explosion-proof devices at emergency explosion at the site and providing return of these structures into initial position after explosion.
