摘要
FIELD: safeguards; explosion-protection devices.;SUBSTANCE: invention relates to explosion-protection devices used in explosive objects. Technical result is achieved by the fact that in explosion-protection structure for fencing explosion-hazardous premises of production facilities, containing reinforced concrete panels of size 6000×1800 mm with perimeter strap for transportation, panel is made in the form of depressions in the building wall and is formed by the planes of a regular quadrilateral truncated pyramid with a circular base, inscribed in its faces in the form of a hole with diameter Dy, there is a body base, made in the form of a plate with a central hole of diameter Dy, equal to the diameter of the hole in the building fence, which is covered by a lined cargo gate movably connected to the base by means of at least three flexible connections, for example in the form of chains, one end of which is hingedly connected to the cylindrical part of the body, and the other one is hingedly connected to the cargo gate, the cylindrical body part is connected to the middle conical and upper cylindrical parts, and in the cylindrical body part, adjoining the conical part, there is a circular diaphragm with a central hole and with at least three holes located in its peripheral part, and between the circular diaphragm and the lined cargo gate there is a bushing made of a rapidly disintegrating material, for example glass, of the "triplex" type, whose strength is calculated for a certain overpressure in the explosion-protection structure, and there is rod coaxial to the bushing, made of a rapidly disintegrating material, axisymmetric to a hole of diameter Dy and fixed to the base of the body on the lined cargo gate, right part of the rod is axisymmetrically located in the central hole of the circular diaphragm.;EFFECT: technical result is increased reliability and efficiency of safe operation of explosion-hazardous premises of production facilities.;1 cl, 2 dwg
