EXPLOSION-PROOF STRUCTURE DAMPING SYSTEM Russian patent published in 2018 - IPC E04B1/92 

FIELD: methods of explosion protection.

SUBSTANCE: invention relates to protective devices used in explosive facilities, such as easy detachable panels and roofs, blast guards. Explosion-proof structure damping system, containing at least three horizontally located rods, by the ends of which disks are fixed, which pass through the holes in the structure protective screen, wherein the disks located on the right side of the rods, are embedded into the building enclosures, and to the disks located on the left side of the rods disposable shock absorbers with collapsible elements are attached. Between the shock absorbers and the protective screen there elastic elements are located pressing the protective screen against the building enclosure through an elastomeric, for example, polyurethane, sealing layer, wherein each of the system shock absorbers is made disposable with collapsible elements made in the form of a placed on the rod bushing, wherein to the disks located on the left side of the rods the shock absorbers damping base is attached by screws, to which a collapsible disposable element bushing is coaxially attached to the rod by screws by means of a flange, made of a brittle quick-collapsible material, for example, porcelain or "triplex" glass, which strength is designed for a certain overpressure in the building enclosure, and the shock absorber resilient part is made in the form of at least three leaf springs placed between the left disk and the bushing-type clamping element with an internal thread cooperating with the threaded section on the rod, at that, on the side facing the left disc the clamping element is provided with grooves for fixing one of the springs ends, at that, the second end of each spring is secured to the left disk by means of hinges, and the springs are arranged with a slope of about 15÷45° in the direction of the collapsible disposable element, at that, on the collapsible disposable element bushing side surface the safety indicator in the form of a resistance strain gage is fixed, signal from which is sent to the strain amplifier via the communication line, and from the strain amplifier is to the emergency operation mode warning system unit.

EFFECT: higher reliability of collapsible explosion-proof devices during emergency explosion at site.
