Problems solved by technology

[0002] At present, for the removal of dangerous ammunition on the surface, artificial bundled explosives are mainly used to induce detonation. This method has low efficiency, poor reliability and safety.
Linear detonators can be used to remove unexploded ammunition on the surface, but linear detonators are sensitive to the explosion height. When used, they can only be attached to the shell of the warhead of unexploded bombs. Sometimes they still need to be fixed manually. Shallow and visible unexploded ordnance in the crater cannot be directly excluded

Abstract

The invention relates to a non-contact energy-gathered igniter. The non-contact energy-gathered igniter comprises a cumulative charge warhead, an explosion transmission assembly and a magnetic electric detonator which are sequentially connected. The cumulative charge warhead comprises a warhead shell, a rubber sleeve, an end cover, an energy-gathered charge shell, explosive and a cartridge shape cover. The cartridge shape cover is arranged inside the energy-gathered charge shell. An airtight clearance is reserved between the cartridge shape cover and the energy-gathered charge shell. The clearance is filled with the explosive. The energy-gathered charge shell is arranged inside the warhead shell. The rubber sleeve is located between the energy-gathered charge shell and the warhead shell. The end cover is installed at the opening of the warhead shell. The non-contact energy-gathered igniter has the beneficial effects that all types of dangerous unexploded ordnances on the earth surface can be destructed through high-speed, high-energy and high-temperature metal jet without making direct contact with the dangerous ordnances. The unexploded ordnances which is small in burial depth and visual in bullet hole can be not excavated, and therefore manual excavation danger is reduced, destruction efficiency of the dangerous ordnances can be improved, and the applied prospect is wide.

Description

technical field [0001] The invention belongs to the technical field of dangerous ammunition destruction, and relates to a method for destroying different postures, Detonating equipment for firing unexploded bombs, throwing unexploded bombs, dropping unexploded bombs, accident ammunition, ammunition with obstacles to technical disposal, old miscellaneous ammunition left over from history and dangerous explosives with unknown technical conditions under different states and terrain conditions, In particular, it relates to a non-contact gathering energy detonating device. Background technique [0002] At present, for the removal of dangerous ammunition on the surface, artificial bundled explosives are mainly used to induce detonation. This method has low efficiency, poor reliability and safety. Linear detonators can be used to remove unexploded ammunition on the surface, but linear detonators are sensitive to the explosion height. When used, they can only be attached to the she...
