Large-equivalent flexible composite explosion-proof equipment

Abstract

The invention discloses large-equivalent flexible composite explosion-proof equipment. The large-equivalent flexible composite explosion-proof equipment comprises a base, a bottomless barrel body andan outer fence arranged on the base, and a top cover fixed to the top of the bottomless barrel body; the outer fence surrounds the periphery of the bottom of the bottomless barrel body; the bottomlessbarrel body comprises an inner support, a barrel body inner container, an inner flexible layer, an outer support and an outer flexible layer which are sequentially arranged from inside to outside, the top ends of the inner support and the outer flexible layer are connected with top edges, the bottom ends of the inner support and the outer flexible layer are connected with bottom edges, and a closed annular cavity is defined by the inner support, the outer flexible layer, the top edges and the bottom edges; the barrel body inner container, the inner flexible layer and the outer support are arranged in the annular cavity; the inner support, the bottom edges and the outer support are made of a first flexible material; the outer flexible layer, the top edges and the inner flexible layer are made of a second flexible material; and the barrel body inner container is filled with explosion-proof liquid. The explosion-proof equipment can effectively resist the explosion impact of large-equivalent explosives.

Description

technical field [0001] The invention belongs to the technical fields of police use, military use and public safety, and in particular relates to a large-equivalent flexible composite explosion-proof equipment. Background technique [0002] Traditional explosion-proof devices generally adopt a hard structure made of steel, which resists shock waves and fragments through its own high strength. However, when dealing with explosives with a large equivalent (≥1kg), there may be a risk of over-explosion, which not only cannot effectively protect the surrounding personnel And objects are protected from the fragments and shock waves produced by the explosion, and its own structure may be deformed and scattered under the action of large-equivalent explosives, causing secondary damage. Moreover, general explosives will have some lethal fragments such as steel balls and nails. Under the high-speed drive of the explosives, such fragments may penetrate or cause the surface of the traditi...
