Abstract
The utility model relates to an exploder without dead bomb, which is suitable for the exploding work in the mining industry and other fields. The utility model only can explode an electric detonator when a conduction circuit is connected in good condition, and can not be charged to explode when a waste detonator and exploding lines are not really connected. The utility model is composed of a conduction measuring unit, an exploding outer connecting rated load measuring unit, a charging and voltage stabling unit, and an electric detonator exploding unit, which are interlocked and restricted mutually.
Description
The utility model belongs to the technical field of safe detonation electric cap in the mining industry.
At present, all types of exploders that use in mining activities generally have only the detonating primer device both at home and abroad; Partly exploder is provided with conducting and measures (detecting the detonator and the circuit of blowing out) device.
Because exploder can not accurately be controlled and blow out line load resistance, be connected fault with circuit blowing out the useless detonator of Shi Yinyou, the miso-fire phenomenon often appears.
At the defective of existing exploder, the purpose of this utility model is to improve its structure, carries out automatic interlock control, reaches no miso-fire, guarantees safe detonation.
Shell of the present utility model is the square box formula, is to be formed by the hot pressing of high strength phenolic aldehyde glass fiber.Leave the demonstration hole of appliance requires on the shell.
Circuit structure of the present utility model such as Fig. 1, circuit theory such as Fig. 2.
The utility model inside is made of four unit, the control of reciprocal interlocking between each unit.
First module is that conducting is measured, by power supply, the normally closed point of measuring switch, LED
1And resistance R
5Constitute.
Be mainly used in the detonator inspection and the inspection of line of blowing out, but must under the shutdown situation, carry out.
Unit second is to blow out external nominal load to measure, and is made of electric bridge, comparator and executive circuit.Switch is put and is measured the position during measurement.When the tested line resistance of blowing out during greater than rated value (overburden), executive component J
1Not adhesive, " conducting " display lamp continues luminous, and trigger does not possess entry condition.When blowing out line resistance when being equal to or less than rated value, executive component J
1Adhesive, " conducting " display lamp extinguishes, and trigger is connected.
Unit the 3rd is a trigger, is made of push-pull converter, rectification circuit, electrochemical capacitor.When switch forwarded " charging " position to, current transformer was connected power supply, starting oscillation, and the high pressure of transformer secondary coil output is through diode D
4Electrochemical capacitor C is given in rectification charging, when capacitance voltage reaches rated value, provides a signal voltage to mu balanced circuit, and accurate quick-fried display lamp is bright, switch can be forwarded to simultaneously to blow out the position and ignite.
Unit the 4th is a charging and voltage stabilizing, by divider R
14, W
2Signal comparator and executive circuit constitute.
When the trigger charging reaches rated voltage, provide a signal voltage through divider to comparator, through BG
3, GB
4Amplify, make relay J
2Adhesive is cut off the electricity supply simultaneously, and current transformer does not recharge.When capacitance voltage was lower than rated value, signal voltage was lower than comparator reference voltage, comparator output zero, and the executive circuit outage, relay recovery, current transformer continues charging, makes trigger keep a burning voltage.
The utility model can be made the different series of products of firing capability (send out number) as required, and the specification that only changes relevant elements in the circuit gets final product.
The utility model design meets every technical indicator of GB3836.1-83 " explosive atmosphere electric apparatus for explosive atmospheres flameproof electrical apparatus ", GB3836.4-83 " explosive atmosphere explosion-proof electric equipment essential safe type circuit and electrical equipment ", GB3836.1-83 " the explosion environment general requirement of electric apparatus for explosive atmospheres " and QIMTE.26J-83 " MFB series exploder is to the relevant requirements of flame-proof mine exploder ".
It is to measure in the conducting of existing exploder that the utility model does not have the miso-fire exploder, on the basis of two kinds of devices of detonating primer, has increased the ignition nominal load and has measured charging and voltage stabilizing and automatic interlocking device.
The utility model volume is little, in light weight, cost is low, safe and reliable, can satisfy the requirement of mining industry safety fire cracker.

Embodiment 1
The shell that selection is formed by the hot pressing of high strength phenolic aldehyde glass fiber, outer casing frontispiece leave the demonstration hole that needs, and inner element material with the subordinate list record is pressed the assembling of Fig. 2 principle.
Selection leaves the demonstration hole that needs by the qualified shell that the hot pressing of high strength phenolic aldehyde glass fiber forms above the shell, Fig. 2 principle is pressed in inside, is made up of the installation elements wiring board.
Selection leaves the demonstration hole that needs by the qualified shell that the hot pressing of high strength phenolic aldehyde glass fiber forms above the shell, inner principle of pressing Fig. 2 is made of four assemblies (conducting divides survey, ignites nominal load measurement, charging and voltage stabilizing, exploder).
