Particularly, the truncated cone-shaped protruding blocks and the cone-shaped explosion-proof cover are both pressure relief structures, the protruding blocks can block metal fragments generated by primary explosion and absorb part of energy, the rest energy is absorbed by the explosion-proof cover, and the pressure of the explosion of the first explosive part is effectively increased by the energy absorption of the combined explosion-proof body.
Description of the drawings:
FIG. 1 is a schematic diagram of the structure of the present application;
FIG. 2 is a schematic diagram of the application in an exploded simulated state;
fig. 3 is a schematic diagram of the application in a simulated state when not exploded.
The specific embodiment is as follows:
the left and right are referred to hereinafter in accordance with the positional relationship shown in fig. 1.
As shown in fig. 1, the serial warhead explosion-proof body comprises a cylindrical shell 1, wherein an outer circular surface provided with a bracket 2 in the shell 1 is connected with the inside of the shell 1 through threads, a first shell 3a is arranged on the bracket 2, a first explosive part 3 is arranged in the first shell 3a, a first liner 3b is adhered to the left end of the first explosive part 3, and the first liner 3b is of a conical structure. The first casing 3a, the first liner 3b, the first explosive section 3, and the first fuse 4 constitute a first warhead.
An aluminum explosion-proof cover 5 is arranged in the shell 1 on the right side of the first fuse 4, the explosion-proof cover 5 is conical, and the outer edge surface of the explosion-proof cover 5 is in threaded connection with the shell 1. The cone head of the explosion-proof cover 5 faces the first fuze 4 to prevent the explosion, a convex block 6 made of polyurethane is adhered to the outer side of the cone head of the explosion-proof cover 5, the outer surface of the convex block 6 is in a trapezoid truncated cone structure, and the top end of the convex block is a plane and is distributed opposite to the right end face of the first fuze 4.
The second shell 7a is connected with the inner thread of the shell 1 on the right side of the explosion-proof cover 5, the second explosive part 8 is filled in the second shell 7a, the shaped charge cover 7 is adhered to the left end of the second explosive part 8, the shaped charge cover 7 is of a conical structure, and a cavity 10 is formed between the shaped charge cover 7 and the explosion-proof cover 5. The liner 7, the second casing 7a, the second explosive section 8 and the second fuze 9 constitute a second warhead.
The second explosive part 8 is filled in the liner 7, and a second fuze 9 is connected to the right end surface of the liner 7 in a threaded manner. The shell 1, the bracket 2, the first explosive part 3b, the first fuse 4, the explosion-proof cover 5, the bump 6, the explosive cover 7, the second explosive part 8 and the second fuse 9 are coaxially distributed.
