The invention further provides another novel detonating device comprising explosive and an ignition device; the detonating device is characterized in that the ignition device is a nano heating tube, the inner wall of the nano heating tube is provided with a glass tube or ceramic tube of nano-metal film, the nano-metal film is electrically connected with an electrode, and the explosive warps the nano heating tube. The novel detonating device allows for cylindrical blasting and capable of generating gathering detonating waves, so that power of the explosive is increased.

Description

technical field [0001] The invention relates to the field of detonation devices, in particular to an electric detonation detonation device capable of detonating on a cylindrical surface and forming convergent detonation waves. Background technique [0002] The detonating device is a device that detonates various explosives by generating detonating energy. The detonator commonly used in blasting engineering is one of the representatives. According to different detonation methods, detonators can be divided into fire detonators, electric detonators and trigger detonators. At present, detonator fuzes mostly use single-point detonation to detonate the main charge. The detonation of the columnar explosive cannot form a converging detonation wave during the process of propagating from the axial outer surface, and its detonation wave velocity, detonation pressure and power of the explosive are also difficult to increase. In addition, the existing various fire detonators, electric d...

AI Technical Summary

Problems solved by technology

According to different detonation methods, detonators can be divided into fire detonators, electric detonators and trigger detonators. At present, detonator fuzes mostly use single-point detonation to detonate the main charge. The detonation of the columnar explosive cannot form a converging detonation wave during the propagation process from the axial outer surface, and its detonation wave velocity, detonation pressure and explosive power are also difficult to improve

In addition, the existing various fire detonators, electric detonators, and trigger detonators are unsafe to store during transportation, and the installation is complicated and costly.
