METHOD OF EXPLOSION PROTECTION WITH DAMPER DEVICE 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. Method of explosion protection consists in performing installation of the explosion-proof elements in the building enclosing structures, in which the explosive and fire hazardous equipment is operating, while for the upper enclosures they are made in the form of anti-explosion panels installed on the roof or attic of the building with the explosive equipment in it, each of which contains a metal armored frame with a metal armored skin and a filler and has four fixed pipe-legs in the ends. Four support rods are rigidly embedded in the building cover, which are telescopically inserted into the fixed pipe supports of the panel, the filler in the panel being in the form of an air-lead disperse system. To ends of support rods, on side facing metal framework there are attached additional elements, damping effect of shock wave, and between the additional elements and the metal frame with the armored metal plating on the load-bearing bars there are bushings from a rapidly disintegrating material, for example, glass of the triplex type, or pneumatic damping elements made of rubber cord shells, for example of a conical shape having a central opening, into which enters a rod, and fixed branch pipe-supports, embedded in the panel, are made in the axial section of a curvilinear shape, for example, hyperbolic. Damping element is made in the form of a homogeneous volumetric body, for example in the form of a damping plate, which is fixed in the upper part of the support rods to the stopping sheets and to which, in the direction of the shock wave, a buffer device is mounted in the form of a cone, the vertex of which is located on the axis of the opening of the protected object, wherein the damping element is formed with an internal cavity which is filled with a three-layer symmetric disperse system, the central layer being a layer of symmetry of the body with an internal cavity and surfaces equidistant to the panel surfaces, are made of a shock-absorbing material, and the adjacent layers are filled with an air-lead disperse system.

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.
