KOCHETOV METHOD FOR PROTECTION OF EXPLOSIVE OBJECTS Russian patent published in 2018 - IPC E04B1/92 

FIELD: safety.

SUBSTANCE: invention relates to protective devices used in explosion hazardous and radioactive facilities, such as blast-relief panels and roofs, blast resistant fences and dampers, excess pressure valves. Method of protection of explosion hazardous facilities consists in the fact that above the open opening of the protected facility, a protective device is installed in the form of a blast-resistant panel designed to relieve excess pressure, wherein the blast resistant panel is made in the form of a metal armored frame with an armored metal skin and a filler, in the form of an air-lead disperse system, the frame being fixed in at least three support rods with stopping sheets in the upper part, which are fixed in the protected facility and telescopically inserted into the fixed support nozzles placed in the blast resistant panel of the protective device, support rods telescopically inserted into the fixed support nozzles of the protective device, are tied to each other through the stopping sheets by elastic-damping elements, To the support rods of the blast resistant panel, telescopically inserted into fixed support nozzles fixed in the panel, to which stopping sheets for fixing the limit position of the panel are welded, a damping plate is attached to which, opposite to the panel and in the direction of the shock wave, a buffer device in the form of a cone is attached, the top of which is located on the axis of the opening of the protected facility.

EFFECT: technical result - increased reliability of explosion-protection devices in case of an explosion at the site and providing the return of these structures into their initial positions after the explosion.
