1. A protective equipment for destruction of explosives, comprising four modules:
an inner fence (1.1), an outer fence (1.2), anti-leakage fence (1.3) and a top cover (1.4); an explosive being a waste military unexploded ammunition or civilian explosive;
wherein
the inner fence (1.1) and the outer fence (1.2) are each of a barrel-shaped structure with openings in two ends, wherein the inner fence (1.1) is in a straight barrel shape, the outer fence (1.2) comprises a conical section and a straight barrel section connected with a small end of the conical section, and the conical section is located below the straight barrel section; the inner fence (1.1) is coaxially arranged inside the outer fence (1.2) in a sleeving manner, and a gap is reserved between the inner fence (1.1) and the outer fence (1.2); the top cover (1.4) covers top openings of the inner fence (1.1) and the outer fence (1.2) to close the top openings of the inner fence (1.1) and the outer fence (1.2); the top cover (1.4) is provided with a through hole running through a space encircled by the inner fence (1.1); the anti-leakage fence (1.3) is arranged at the periphery of the outer fence (1.2);
the outer fence (1.2) comprises: an outer fence bottom supporting plate (1.2.1), an outer fence kinetic energy absorption layer (1.2.2), an outer fence ammunition protection layer (1.2.3), an outer fence outer supporting layer (1.2.4), an outer fence top supporting plate (1.2.5), an outer fence bottom reinforcement layer (1.2.6) and a shock wave bottom enhanced absorption layer (1.2.7);
the outer fence (1.2) is of a three-layer structure, comprising the outer fence kinetic energy absorption layer (1.2.2), the outer fence ammunition protection layer (1.2.3), and the outer fence outer supporting layer (1.2.4) in sequence from inside to outside; the ringlike outer fence top supporting plate (1.2.5) is arranged on a top axial end surface of the outer fence (1.2); the ringlike outer fence bottom supporting plate (1.2.1) is arranged on a bottom axial end surface of the outer fence (1.2);
the outer fence bottom reinforcement layer (1.2.6) and the shock wave bottom enhanced absorption layer (1.2.7) are arranged at the periphery of the bottom of the outer fence (1.2); an inner surface of the shock wave bottom enhanced absorption layer (1.2.7) is a circumferential surface, and an outer surface is a conical surface; the outer fence bottom reinforcement layer (1.2.6) is located between the shock wave bottom enhanced absorption layer (1.2.7) and the outer fence outer supporting layer (1.2.4); and
the outer fence bottom reinforcement layer (1.2.6) uses ammunition protection fiber, and the shock wave bottom enhanced absorption layer (1.2.7) is a package bag filled with explosion-proof decontamination liquid.
