PROTECTIVE DEVICE FOR EXPLOSIVE OBJECTS Russian patent published in 2018 - IPC E04B1/92 

FIELD: protective devices.

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 objects contains a metal armored frame with an armored metal shell and a filler which is made in the form of an air-lead dispersed system, wherein lead is made in form of chips, and frame has fixed branch pipes-supports at ends, and in the cover of the explosive object, at least three supporting rods with leaf stops in the upper part are rigidly fixed, which are telescopically inserted into the fixed pipe-supports in a metal armored frame. In upper part of base rods elastic damping elements are fixed, one end of which is rigidly connected by its base to plates-stops, and the other is freely disposed, each of the resiliently damping elements being fixed by means of screws with a base made in the form of a circular disk of rigid vibration cushioning material of the "Agat" type, on the stop plates rigidly connected to the rods, and the base of the resiliently damping element is connected to an elastomer bushing having a central hole through which the rod passes, the bushing having at least three holes coaxial with the stem, in which elastic elements are arranged, for example, cylindrical helical springs, the upper end of which is connected by means of fastening elements to the base, and the lower one is in an unlatched state and protrudes beyond the lower plane of the sleeve by a distance determined by the force developed by the shock blast wave, each of the support rods being hollow with a set of damping disks in the inner cavity.

EFFECT: higher reliability of explosion-resistant device operation during emergency explosion at the facility, and ensured return of these device to the original position after explosion.
