Example Embodiment

[0023] The present invention will be further described in detail below with reference to the drawings and specific embodiments.

[0024] Use as figure 1 , figure 2 The indoor environment explosion-proof performance test device of a composite flexible explosion-proof device is shown, and the indoor explosion-proof performance of a flexible explosion-proof structure is experimentally evaluated. Suppose its working conditions are: protection against fragmented explosives in the business halls of ordinary small banks, and the TNT equivalent of the explosives is 3kg.

[0025] The following is the specific process of experimental evaluation:

[0026] (1) Determine the explosion-proof performance test experiment and arrange a flexible explosion-proof structure at the center of the experimental evaluation device;

[0027] (2) Install a wall-type shock wave sensor at the steel pipe in the center of the floor;

[0028] (3) According to actual needs, it is necessary to evaluate the explosion-pr...

Abstract

The invention discloses an indoor environment explosion protection performance testing device for a combined flexible explosion protection device and belongs to the field of social public security. The indoor environment explosion protection performance testing and evaluating device for the combined flexible explosion protection device comprises a floor slab (5), brick walls (1), a biological target (2), an overpressure testing device (3), a human body simulation target (6), a measured object (4) and the like, wherein the floor slab (5) is formed by pouring concrete, the floor slab (5) is arranged at the upper edges of the two brick walls (1), and the measured object (4) is arranged on a floor (7) in the center of a room. The indoor environment explosion protection performance testing device disclosed by the invention has novel design, reliable evaluation result, low experiment cost, strong generality, application to protection performance evaluation of a flexible explosion protection structure to maximum equivalent explosive in an indoor public place of a brick-concrete structure and ability in solving the problem about indoor explosion protection performance of a current flexible explosion protection structure for dealing with explosive.

Description

technical field [0001] The invention relates to an indoor environment explosion-proof performance test device of a composite flexible explosion-proof device, in particular to an indoor environment explosion-proof performance test device of a composite flexible explosion-proof device, which belongs to the field of social public security. Background technique [0002] Because of its concealment, simple implementation, and large-scale damage, explosive terrorism is likely to create a long-lasting and widespread social terror atmosphere. It has become the most commonly used, most common and most destructive form of activity by terrorists today. Explosion terrorist attacks and explosion-related criminal offenses have become one of the main threats to public security at home and abroad. [0003] The traditional use of steel explosion-proof containers for the rigid protection of explosives has many problems. For example, explosive terrorist activities are random and uncertain, that...
