Electronic ignition delay detonator

Abstract

The invention provides an electronic ignition delay detonator. The electronic ignition delay detonator comprises an electronic control module, an electric ignition powder head, a pyrotechnic delay body and a base detonator, wherein the electric ignition powder head is fixedly and electrically connected with the electronic control module with an electronic password control function and an electronic timing function to form an electronic ignition piece; the electronic ignition piece and the pyrotechnic delay body are packaged in a base detonator shell; the electric ignition powder head is opposite to an open end of the pyrotechnic delay body; and the electronic ignition piece controls the electric ignition powder head to ignite the pyrotechnic delay body after delay, and the pyrotechnic delay body burns for a set time to detonate the base detonator. The electronic ignition delay detonator not only has the management and control functions of an industrial digital electronic detonator, being convenient to use, but also has the ignition reliability of a traditional delay detonator.

Description

technical field [0001] The invention relates to the technical field of civil blasting equipment, in particular to an electronic ignition delay detonator. Background technique [0002] Industrial detonators are widely used civilian detonators. Under the requirements and promotion of relevant policies of the Ministry of Industry and Information Technology and the Ministry of Public Security, my country has widely promoted the use of industrial electronic detonators, also known as industrial digital electronic detonators. [0003] Industrial electronic detonators are mainly composed of electronic components through functional combinations to form industrial detonators that can meet the requirements of engineering blasting. There are special electronic control modules inside the industrial electronic detonators to control the ignition time and duration of the ignition elements in the detonators. Realize the specific delay time length of the industrial detonator, with the charact...

Problems solved by technology

[0005] However, since these high-precision electronic devices and electronic circuits are housed in the detonator body, the inevitable and irresistible electromagnetic occasions, induced electric shocks, detonation wave action, and seismic wave extrusion will be encountered during use. Sections, foundation piles on small working faces, small roadway excavation, hard ore deposits, ore mining and other explosive operations are strongly affected, resulting in strong induction electricity being introduced into the electronic control module in the detonator body by the foot wire connected to each detonator, forming Electrical shocks lead to failure of the electronic control module, misfiring or loss of guns

However, the detonation wave generated by the first explosive in the blast hole scans the detonator body through the ground, which will cause the entire electronic module to be impacted by a huge force. These factors will cause dangerous situations such as blind fire, lost guns, and accidental explosions of industrial electronic detonators during the actual use of guns.
