PROTECTIVE DEVICE FOR EXPLOSIVE OBJECTS Russian patent published in 2016 - IPC E04B1/98 F42D5/45 

FIELD: safety.

SUBSTANCE: invention relates to protective devices, namely, to protective devices for explosive objects. Includes metal armored frame with armored metal plating and filler. Latter is composed of air-lead disperse system. Lead is made in form of chips. Frame has at ends fixed branch pipes-support. In coating of explosive object is rigidly fixed, at least, three support rods with plates-stops in upper part. Rods telescopically inserted into fixed branch pipes-support in metal armored frame. In upper part of support rods are fixed elastic-damping elements, one end of which is rigidly connected by its base with plates-stops, and other is located freely. Each of elastic damping elements is fixed by means of screws with its base on sheets-thrusts rigidly connected with rods. Base elastic-damping element is connected to sleeve made from elastomer with central hole, through which rod is passed. Sleeve has at least three holes aligned with rod, in which there are elastic elements, for example, cylindrical helical springs. Top end thereof by means of fastening elements is connected with base, and bottom is in non-compressed state and protrudes beyond sleeve bottom plane at distance defined by force generated with impact blast wave. Higher reliability of operation of explosion protective devices at emergency explosion at the site.

EFFECT: provides for return of structures to initial position after explosion.
