Accompanying drawing is the circuit diagram of the utility model embodiment.
The specific embodiment
Below in conjunction with embodiment the utility model is further specified:
As shown in the figure, this exploder is made of flameproof enclosure, power panel, control panel and exploder plate, and power panel, control panel and exploder plate are installed in the flameproof enclosure, and for preventing electromagnetic interference, is placed on respectively in the different chambeies.
Two power output ends are arranged on the power panel, and it adopts the circuit mode of transformer step-down, full-bridge rectification, filtering, voltage stabilizing to provide the two-way power supply to control panel and exploder plate.
The exploder plate adopts that the higher-order of oscillation, transformer boost, detonating of electric cap carried out in capacitor energy storage, artificial turn millisecond time-delay switch.The basic principle that adopts the exploder of MFB100 type in the present embodiment, only with the dry cell among the former figure, change the power panel power supply into, relay Q4 in the control panel can control its power supply, ND is a neon lamp, in order to the indication charged state, K is the millisecond time-delay switch, and H1 and H2 are the shot firing cable binding post.
Control panel is the core of this interlocking exploder, it be by universal logic module LOGO! , three band keys press button SB1 with lock～3, three indicator lamp LED1～3, three a current-limiting resistance R1～3 form, universal logic module LOGO! The key that contains pin I1～4 and relay Q1～4, three press button with lock is worn by class monitor and group leader, fireboss and fireman respectively; Pin I4 inserts gas detection device terminal, can carry out automatic blocking control to the bursting work place, and when gas density transfinited, the interlocking exploder can provide caution and forbid powering to the exploder plate; Three indicator lamp LED1～3 are in order to show current working state, with different colours or printed words representative " operate as normal ", " powder charge " and " explosion " operation.
On the power panel positive pole of a power output end by press button SBE1 with lock connect LOGO! Pin I1, connect pin I2 by press button SBE2 with lock simultaneously, connect pin I3 by press button SBE3 with lock, connect pin I4 by gas detection device terminal, the negative pole of this power output end is successively by relay Q1, indicator lamp LED1 is connected the positive pole of this power output end with current-limiting resistance R1, the negative pole of this power output end is successively by relay Q2 simultaneously, indicator lamp LED2 is connected the positive pole of this power output end with current-limiting resistance R2, and the negative pole of this power output end is successively by relay Q3, indicator lamp LED3 is connected the positive pole of this power output end with current-limiting resistance R3; The positive pole of another power output end is by the positive pole of power input on the relay Q4 connection exploder plate on the power panel, and the negative pole of this power output end connects the negative pole of power input on the exploder plate, and relay Q4 control is to the electric power loop of exploder plate power supply.
The operation principle of this exploder is as follows:
When getting working face does not carry out the relevant operation of explosion, on the control panel LOGO! Q1 keep adhesive, LED1 (operate as normal) lamp keeps Chang Liang; Q4 opens, and exploder plate non-transformer can not charge to detonation plate capacitor C 11～14, promptly can not carry out explosion.When the operation perforating finishes, when desiring to carry out bursting work, must operate by following several processes:
1, the class monitor and group leader withdraws from personnel, presses SB1 with key, universal logic module LOGO! I1 get electric, carry out corresponding computing after, open Q1, interrupted adhesive Q2, then Zhuan Zhi LED1 (operate as normal) extinguishes, LED2 (powder charge) flicker, the signal fireboss carries out the preceding gas detection of powder charge.
2, the fireboss carries out gas detection before the powder charge, as qualified, then presses SB2 with key, then universal logic module LOGO! I2 get electric, carry out corresponding computing after, adhesive Q2, then LED2 (powder charge) no longer glimmers, and keeps Chang Liang, gas detection is qualified before the signal powder charge, can powder charge.
3, the fireman carries out powder charge.After powder charge finishes, press SB3 with key, universal logic module LOGO! I3 get electric, carry out corresponding computing after, open Q2, interrupted at a slow speed adhesive Q3, the LED2 of device (powder charge) lamp extinguishes, LED3 (explosion) glimmer at a slow speed, powder charge is finished in signal, the preceding gas detection of application explosion, and warning is set.
4, the fireboss carries out gas detection before the explosion, as qualified, then presses SB2 with key, universal logic module LOGO! I2 get electric, carry out corresponding computing after, fast interrupted adhesive Q3, the LED3 of device (explosion) fast blink, gas detection is qualified before the signal explosion, class monitor and group leader's explosion of can ordering.
5, the class monitor and group leader rechecks operation field, operations such as warning is set, and after finishing, presses SB1 with key, universal logic module LOGO! I1 get electric, carry out corresponding computing after, the Q3 adhesive, the LED3 of device (explosion) no longer glimmers, and keeps Chang Liang, enters the blasting work state.And if only if this state, on the control panel LOGO! The Q4 adhesive, the exploder plate gets electric, the fireman can be connected to shot firing cable H1 and H2, left-handed millisecond time-delay K switch is charged.Charging finishes, and neon lamp lights, and gets final product dextrorotation millisecond time-delay K switch, carries out explosion.
6, explosion after the fireman blows a whistle.Explosion finish and passed examination after, the fireman presses SB3 with key, universal logic module LOGO! I3 get electric, carry out corresponding computing after, open Q3, interrupted at a slow speed adhesive Q1, the LED3 of device (explosion) extinguishes, LED1 (operate as normal) glimmer at a slow speed, the signal explosion finishes, and applies for carrying out the inspection of explosion after gas.At this moment, universal logic module LOGO! Q4 open, cut off power supply to the exploder plate.
7, the fireboss carries out the inspection of explosion after gas, as qualified, then presses SB2 with key, universal logic module LOGO! I2 get electric, carry out corresponding computing after, fast interrupted adhesive Q1, the LED1 of device (operate as normal) fast blink, signal big gun after gas passed examination, squad leader's normal operation of can ordering to recover.
8, the class monitor and group leader at first enters working face inspection, as possesses normal running conditions, then presses SB1 with key, universal logic module LOGO! I1 get electric, carry out corresponding computing after, adhesive Q1, then Zhuan Zhi LED1 (operate as normal) keeps Chang Liang, the signal bursting work is finished, and can recover the operation that other has nothing to do with explosion, i.e. normal operating conditions.
Like this at 2,4,7, the fireboss finished before the powder charge, it is preceding to blow out and blow out after gas detection, finished " big gun three inspections ".3,4,5 specified content of then finishing " three people interlocking is blown out ".Formed a perfect bursting work circulation.
Pin I4 on the control panel connects gas detection device terminal, can insert gas detection device as required.After the access, as on-the-spot gas exceeding limit, then powder charge and explosion two indicator lamps fast blink simultaneously, the caution relevant personnel take corresponding measure, forbid simultaneously LOGO! The Q4 adhesive, can not carry out bursting work.
