Abstract

A simple nonel detonating device, the nonel detonating device includes a nonel, an electric spark device and a detonator, and the electric spark device includes a fixed column and two discharge wires, and the fixed column is arranged on the nonel One end, one end of the discharge wire is connected to the detonator, and the other end passes through the fixed column and goes deep into the tube body of the detonator. The detonator and the fixed column are connected through a connecting sleeve. There is a step for fixing the detonating tube, and the other end of the connecting sleeve is provided with a boss matching the slot provided on the fixing post. When the utility model is in use, the detonator generates a high-voltage arc at the head of the discharge wire to detonate the explosive on the inner wall of the detonator, which can play the role of an electric detonator, because the detonator detonator has no sensitive electric detonator Explosive, so its storage and use are extremely safe; at the same time, the device has the advantages of simple structure and convenient use.

Description

A simple nonel detonating device

technical field

The utility model relates to the field of blasting equipment, and is particularly suitable for detonating plastic detonating tubes, in particular to a simple detonating tube detonating device.

Background technique

The nonel is an important invention of modern blasting equipment. It relies on a thin layer of explosive attached to the wall of the plastic tube to propagate the detonation wave. It has the advantages of stable detonation transmission and high safety performance. In 2008, the country canceled the use of fire detonators and fuses, and directly used electric detonators, which required strict control of stray currents at the blasting site.

In modern blasting technology, nonel detonators and nonel blast transmission networks are widely used, which provide a guarantee for improving the safety and reliability of blasting technology. At present, the method of detonating the nonel detonator and the nonel network is mainly an electric detonator or a trigger pen. The electric detonator is easily detonated by stray current, lightning and radio frequency electricity, and there is a huge potential safety hazard; Partial oxidation requires grinding, anti-corrosion and other maintenance, which is very inconvenient, and must be replaced after reaching the service life, which cannot be used conveniently and continuously, and there is also the problem of low detonation safety. Therefore, it is of great significance to develop a device that can replace the electric detonator and can detonate the nonel safely and reliably.

Utility model content

The technical problem to be solved by the utility model is to overcome the potential safety hazards in the nonel detonation in the prior art, and provide a simple nonel detonation device, which has the characteristics of simple structure, convenient use and high safety.

The technical solution adopted by the utility model for solving the above problems is: a simple nonel detonating device, which includes a nonel, an electric spark device and a detonator, and the electric spark device includes a fixed column And two discharge wires, the fixed column is arranged at one end of the nonel, one end of the discharge wire is connected to the detonator, and the other end passes through the fixed column and goes deep into the tube body of the nonel, the nonel and the fixed column They are connected by a connecting sleeve, the inner wall of one end of the connecting sleeve is provided with a step for fixing the nonel, and the other end of the connecting sleeve is provided with a boss matching the slot provided on the fixing column.

The detonating tube is a plastic detonating tube, the inner wall of which is coated with explosive powder.

The fixing post is made of epoxy resin.

Beneficial effects: when the nonel detonating device is in use, the high-voltage arc is generated at the head of the discharge wire by the detonator, and the explosive on the inner wall of the nonel is detonated, which can play the role of an electric detonator. Since the nonel detonating device There is no sensitive explosive in the electric detonator, so its storage and use are extremely safe; at the same time, the device has the advantages of simple structure and convenient use.
