Description

A kind of pocket Nonel detonator timed detonation device

Technical field

The utility model is used for mine blasting timed detonation, belongs to industrial explosive material priming device field.

Background technology

2008, country was ordered after forbidding production and sales blasting cap and fuse cord, and mine is carried out quick-fried using Nonel detonator Need the safety place that the detonator using more than 500 meters is led to outside quick-fried area during broken operation, then with initiator detonation tube thunder Pipe, detonator payingoff construction is very time-consuming, and detonator is disposable, and every meter of market price wants 0.3 yuan, and 500 meters will 150 First expense.To reduce blast working cost, saving the engineering time, a kind of pocket Nonel detonator timed detonation dress has been invented Put, the priming device is placed in quick-fried area by the installation cost less than 30 yuan, during use（Do not reclaim）Or near quick-fried area（Recovery repeats Use）, after start by set date, can there is time enough to allow workmen to withdraw from quick-fried area to safety zone.

The content of the invention

The purpose of this utility model is when solving current mine blasting operation, to be led to 500 meters of long detonators outside quick-fried area Safety zone detonated again, the problem of job execution efficiency is low and costly.The volume of the utility model only have 150mm × 75mm × 50mm, it is very convenient to carry.The utility model is by storage capacitor, circuit board, direct current oscillation boosting module, mechanical fixed When device, housing, two section No. 5 batteries, battery cabin cap, timer knob, upper lid, Light-Emitting Diode, two binding posts, fire pin, Power switch, resistance, wire and screw are formed.The critical component of the priming device is that mechanical timer and small-sized direct current shake Boost module is swung, timer is the common mechanical timer of in the market, by the orderly connection of its internal switch, can control storage The charge and discharge of energy electric capacity, can regularly 1 minute to 15 minutes；The effect of small-sized DC oscillation boosting module is to save No. 5 by two 3 volts of boost in voltage are to 2000 volts caused by battery strings company.Housing, upper lid in the priming device are formed using plastic injection, it Play a part of fixed and protect inner components, upper lid and battery cabin cap use unitary design, can save injection mold Cost.Power supply is composed in series by 2 No. 5 batteries of section.Storage capacitor uses nonpolarity high pressure resistant electric capacity, is risen for storing direct current vibration High voltage electric energy caused by die block, to produce the electric spark of enough energy on percussion pin.Light-Emitting Diode uses red, Instruction as on/off.The effect of resistance is connected with Light-Emitting Diode, plays a part of partial pressure, current limliting, avoids lighting Diode burns because voltage is excessive.The effect of two binding posts is the two poles of the earth of connection percussion pin.It is thin-walled to fire pin outer electrode Metal tube, central electrode are wires, are insulating barrier between wire and thin metallic tubd.Circuit board and wire are by each electronics Part carries out soldering connection by circuit theory diagrams, formed with continuous circuit.The effect of screw is by mechanical timer, circuit Plate, upper lid are fixed together with housing.
