A mechanical safety detonator

Abstract

The invention relates to a mechanical safety detonator which comprises a shell, wherein an inner threaded pipe is fixed above the shell; a safety plug is arranged in the inner threaded pipe; the upper part of the shell is symmetrically connected with two rotating rods; a tension spring is connected between the two rotating rods; the two rotating rods are connected with an electric control switch and a power supply through wires; the electric control switch and the power supply are connected to a heat conduction sheet through wires; the heat conduction sheet is fixed in the shell; a first pipe, a second pipe, a third pipe and a fourth pipe are fixed below the heat conduction sheet; white phosphorus is contained in the first pipe; delay powder is arranged between the second pipe and the third pipe; detonation powder is arranged between the third pipe and the fourth pipe; a high explosive is arranged between the fourth pipe and the shell; a plurality of enhancement pills are arranged in the high explosive. The mechanical safety detonator has the advantages of reasonable structure, high safety, convenience in use, high explosion power and the like, and can achieve an ideal detonation effect.

Description

technical field [0001] The invention relates to a mechanical structure detonator, in particular to a mechanical safety detonator. Background technique [0002] The detonator is the main detonating material in blasting engineering. Its function is to generate detonation energy to detonate various explosives and detonating cords. The detonator is generally equipped with a charge head, a delay charge, a priming charge and a high explosive. The high explosive is the final detonation of the detonator. thing. Usually the charge, the delay charge, the priming charge and the high explosive are placed in each section in a detonator. After the charge is ignited, it takes a certain delay to reach the high explosive. The time of energy explosion is not concentrated enough, which will inevitably weaken the detonation effect. Moreover, putting the drug head, the delay charge, the priming charge and the high explosive all together is likely to cause safety hazards, so it is necessary to s...

Problems solved by technology

Usually, the charge, the delay charge, the priming charge and the high explosive are placed in each section of a detonator. After the charge is ignited, it takes a certain delay to reach the high explosive. The energy burst time is not concentrated enough, which will inevitably weaken the detonation effect.
