Problems solved by technology

Therefore, the existing delay detonators generally have defects such as inaccurate delay time and poor consistency of delay time, which are limited in use and cannot be used in high-precision controlled blasting
With the development of blasting technology, there is an urgent need to further improve the delay time accuracy of the delayed initiation system, and the existing delay detonators can no longer meet the requirements of high-precision controlled blasting

Embodiment Construction

[0015] Embodiment of the present invention: In this embodiment, the detonator body (1) containing the bottom explosive (3) can be manufactured by the method of the prior art. When manufacturing, an electronic device is connected to the front end of the wire (2). Delayer (5), and connect a igniting powder head (6) to the output end of the electronic delayer (5). The electronic delayer (5) can be a finished product sold in the market, but it is best to use a commercially available product. The smart chip for sale is a specially made cryptographic electronic delayer, that is, the electronic delayer (5) can be made by using a smart chip integrated block (U) with a rewritable password function of the model PLD on the market. When connecting a transistor G1 emitter, resistor R3 and capacitor C2 to pin 1 of the smart chip integrated block (U), connect a pin C3 and C4 to the pin 2 and pin 3 of the smart chip integrated block (U). The oscillating signal circuit composed of crystal oscillat...

Abstract

The prodn. method of safety detonator is that conducting wire is connected with detonator body, bottom explosive is put in bottom of detonator, force-end of conducting wire is encapsulated on top of the detonator by elastic PVC plastic plug, an electric time delay unit is connected with force-end of the conducting wire, igniting powder head is connected with out-end of the electric time delay unit. The delay time can be set to 1-30 section with equally interval 20 millisecond, delay error is less than 5 millisecond.

Description

Technical field: [0001] The invention relates to a safety detonator and belongs to the technical field of detonators. Background technique: [0002] At present, most of the deferred detonators used in the prior art use the common agent deferred body technology, which uses the method of controlling the burning time of the delayed agent to obtain the deferred time, and the delay time error is large, especially when applied to the high-level deferral. The error of the detonator is as high as hundreds of milliseconds. Even the newly-researched high-precision detonator at equal intervals has an interval of 50 milliseconds for sections above 16 and an error of 40 milliseconds. The interval for sections above 25 is 50 milliseconds. 80 milliseconds, the error reaches 60 milliseconds, the higher the segment, the greater the delay time error. Therefore, the existing delayed detonators generally have defects such as inaccurate delay time and poor consistency of delay time, which are subject...
