Abstract
The present invention relates to a digital display type blasting device with a test device, which is composed of the test device and a blasting device, wherein the test device is formed by the connection of a power supply, a test signal input end, an A/D converter and a liquid crystal display. The charging voltage stabilizer of the blasting device is formed by the connection of voltage division resistors R11, R10, a neon bulb ND, BG2 and BG3. The igniter of the blasting device is composed of a push-pull type current transformer, a voltage doubling and rectifying circuit and main capacitors C8 to C11. The present invention has the advantages of simple structure, convenient and sample use, sensitive and accurate display, safety, reliability, small volume, light weight and low manufacturing cost, and is suitable for the safe blasting of mining industry especially coal mines with methane (gas).
Description
The invention belongs to the design and the manufacturing technology field of the used exploder of mining industry, it is applicable to the safe detonation electric cap.
Current, as at home and abroad to use in the mining all kinds of exploders generally have only the detonating primer device.Connecting the situation testing arrangement though the part detonator has the test miso-fire and blows out the networking, is that light shows entirely, tests inaccurate.Since exploder can not measure exactly blow out bus short circuit, open circuit and the connection situation (detonator quantity) at detonator networking, miso-fire often appears and the busbar short-circuit of blowing out causes spark, cause accidents such as gas and coal-dust explosion.
At the defective of existing exploder, the purpose of this invention is to provide and a kind ofly measure detonator quantity that is connected and the connection situation of blowing out bus of once blowing out exactly, and have the digital display type blasting apparatus of stable-pressure device, testing arrangement with digital display.
Shell of the present invention is rectangular boxlike.Adopt the hot pressing of high strength phenolic aldehyde glass fiber to form.Leave needed display window of instrument and shift knob on the shell.
The present invention is made of testing arrangement and exploder two parts.The former is single unit, and the latter is made of stable-pressure device and two unit of trigger.
The structure of first module-testing arrangement as shown in Figure 1, its line construction such as Fig. 2.It is made up of power supply, test signal input, A/D converter, liquid crystal indicator.Each part is connected on the same circuit version successively.
This unit is used for the quality examination of detonator, blows out the inspection of bus connection situation, and can measure the number of connection of detonator in the network exactly.Can prevent the explosion accident that miso-fire and line short circuit etc. cause.
The structure of second and third unit-stable-pressure device and trigger as shown in Figure 3, its line construction is as shown in Figure 4.
Second unit-charging and voltage stabilizing device is by divider resistance R

The course of work of this unit is: when trigger charges to rated voltage, by divider resistance R
11, R
10, neon bulb ND, triode BG

3One signal voltage is provided, makes it conducting.Thereby locking BG
1The R oscillation circuit.Current transformer does not recharge, and prevents the main capacitance over-voltage breakdown.And when charging voltage descends, R
11, R
10, the signal voltage deficiency that provides of neon bulb ND is so that triode BG

3Conducting, current transformer continues charging, makes exploder guarantee that stable voltage is arranged, and damages components and parts to guarantee its safe detonation and to prevent because of the charging overvoltage.
The 3rd unit-trigger is by push-pull converter, voltage doubling rectifing circuit and main capacitance C

11Constitute.Its course of work is:
When switch placed " charging " position, current transformer was connected power supply, starting oscillation, and the high pressure of transformer secondary coil output is through diode D

4Behind the voltage multiplying rectifier, give main capacitance-electrolytic capacitor C
8-C
11Charging, when voltage reached rated value, accurate quick-fried lamp ND was luminous, and go to switch " blowing out " position and then can ignite electric cap this moment.
The present invention can be as required firing capability (detonating primer quantity: 50,100,150,200 etc.), make different series of products, as long as change relevant elements quantity and specification in the circuit.
The present invention meets the multinomial specification requirement of GB3836.1-83 " the explosive atmosphere general requirement of electric apparatus for explosive atmospheres flameproof electrical apparatus ", GB3836.4-83 " the explosion environment general requirement of electric apparatus for explosive atmospheres " and GB7958-87 " the colliery relevant requirements of capacitor blasting machine ".
Advantage of the present invention is, structure is ingenious, and is easy to use, shows sensitive and accurately, safe and reliable, and volume is little, and is in light weight, and cost is low, can satisfy mining industry, particularly safety fire cracker requirement in the colliery of methane (gas) be arranged.
