Detonating tube electronic delay detonator and method for detonating detonator under double control of light and shock waves

Abstract

The invention relates to a detonating tube electronic delay detonator and a method for detonating the detonator under the double control of light and shock waves. The detonating tube electronic delay detonator comprises a detonating tube, a basic detonator body and an electronic delay control device. The electronic delay control device comprises an AND gate electronic delay detonation circuit, an electric firing head, a light signal converter and a shock wave circuit breaker, wherein the electric firing head is connected with the output end of the AND gate electronic delay detonation circuit, the light signal converter receives a light signal after the detonating tube is detonated to enable one control end of the AND gate electronic delay detonation circuit to be switched on, and the shock wave circuit breaker receives a shock wave signal after the detonating tube is detonated to enable the other control end of the AND gate electronic delay detonation circuit to be switched on. The electronic delay control device carries out the double control through the light and the shock waves, the light signal converter and the shock wave circuit breaker can trigger the AND gate electronic delay detonation circuit to start a delay procedure after simultaneously switching on the respectively controlled control ends, and after set time is up, the electric firing head emits fire to detonate the basic detonator body.

Description

technical field [0001] The invention relates to the technical field of detonation detonators, in particular to a nonel electronic delay detonator and a method for using light and shock wave dual control detonation nonel electronic delay detonators. Background technique [0002] With the development of blasting technology, electronic detonators have been used in conventional blasting systems, but due to the application and popularization of modern equipment, static electricity, electromagnetic waves, radio frequency stray currents, etc. have also increased relatively, which brings certain problems to the use of conventional electronic delay detonators harm. At present, most of the electronic detonators in my country use electronic leads to detonate the detonators after the detonator is energized. Tube detonators began to be developed and widely used. However, its disadvantage is that it is difficult to achieve high precision by means of chemical combustion delay, and the det...

Problems solved by technology

For example: when there is a sudden change in the external temperature, the same non-electricity in the outside world is directly discharged on the sensitive element and converted into a switching electrical signal, and when there is a sudden strong shock wave vibration in the outside world, it may cause false explosion; during use and transportation, once encountered When a certain emergency occurs, the nonel electronic delay detonator will explode by mistake, which may have a great impact on national production safety, bring losses to people and property, and lead to irreparable consequences
