Multiple detonation holes are arranged on the upper end of the destruction device, and each detonation hole is distributed in the form of an annular array along the central axis of the destruction device. The detonation hole is cylindrical, and its space is formed by the detonation hole shell penetrating the top shell and embedded in the upper end of the charge, and the expansion charge is preloaded at the bottom of the detonation hole shell. A detonation hole plug is arranged above the expansion charge, and is used for fixing the expansion charge together with the detonation hole shell, and a circular through hole is arranged in the center of the detonation hole plug for inserting a detonating cord. One end of the detonating cord is in close contact with the expansion charge through the central through hole of the detonating hole plug, and the other end is connected with the detonating charge column. The batch, length and diameter of each detonating cord are the same. Because the detonating cord has a high detonation velocity , can achieve multi-point synchronous detonation. The third is to use the appropriate detonation sequence. When carrying out the destruction operation, firstly detonate the priming charge, the priming charge detonates the detonating cord, the detonation index detonates the expanding charge, and then detonates the main charge. The fourth is to utilize the principle of detonation wave collision. After the explosion of the expanding charge, the adjacent main charge is firstly detonated. Since the positions of the detonating holes are arranged in a circular array, detonation waves can be generated at the corresponding positions in the main charge. Based on the principle of detonation wave collision, it can generate Far greater than the overpressure of the center point detonation, so as to realize the energy amplification output of the jet. To sum up, the utility model adopts a shaped charge structure, and a plurality of detonating holes are arranged on the upper end of the detonating body, and the expansion charge is pre-installed in each detonating hole, and multi-point synchronous detonation is realized from the position of the detonating hole through the detonating cord. Using the principle of detonation wave collision and energy-gathering effect to realize the amplification and directional output of detonation energy, so as to safely and reliably detonate the ammunition to be destroyed and achieve the purpose of explosive destruction.
