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

Embodiment 1

[0031] This embodiment provides an electronic ignition delay detonator, such as figure 1 As shown, it includes an electronic control module, an electric ignition charge 6, a pyrotechnic delay body 4 and a basic detonator.

[0032] The electronic control module is an electronic module composed of components made of analog circuits or digital circuits or analog circuits / digital circuits, with power supply functions, address code and password registers, communication and control functions, and energy release functions. The module is fixed and electrically connected with the electric ignition powder head 6 to form an electronic ignition part 7, and the exterior of the electronic ignition part 7 is wrapped in plastic to form a cylindrical plastic column to form a glue-sealed electronic ignition part 8.

[0033] The electronic igniter 7 has address code storage function, switch control password storage function, timing and control switch function, communication function with detonat...

Embodiment 2

[0043] Such as figure 2 As shown, the electronic control module is fixed and electrically connected with the electric igniter tip 6 to form an electronic igniter 7, and the exterior is not wrapped with plastic. The pyrotechnic delay body 4 of the second embodiment adopts a single-core delay body. Other structures and uses are consistent with Embodiment 1.

Embodiment 3

[0045] Such as image 3 As shown, the exterior of the electronic control module is wrapped in plastic to form a cylindrical plastic column, and the plastic column fills the matching gap between the electronic ignition part 7 and the base detonator shell 1 . The delay charge 5 is filled in the bottom of the closed end of the pyrotechnic type delay body 4 shell, and the delay charge 5 is opposite to the electric ignition charge head 6 . Other structures and uses are consistent with Embodiment 1. The structural assembly of the third embodiment is simple.

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...
