Abstract
An interlocking voltage regulation digital display exploder used for an electric detonator utilizes an electric non-consuming digital panel meter and is equipped with an interlocking control mechanism and a protective resistance Rb. A battery and a digital panel meter of the electric non-consuming digital panel meter are mutually connected with a contact point K1-1 of a delay K1. The testing terminal X1 and the testing end 1 N+ are mutually connected with the contact point K1-2 of the delay K1. The interlocking control mechanism connects a reed tube and the delay K1 between the battery and the power supply road of a circuit board. The protective resistance Rb is connected between a high voltage capacitor C and a negative electrode of the power supply. The interlocking voltage regulation digital display exploder has advantages of a good safety performance and greatly reduces the failure rate of the exploder because of the electric non-consuming digital panel meter, the interlocking control mechanism, the protective resistance and the protective main circuit.
Description
Technical field
The utility model belongs to the electric cap exploder that detonates, the design and the manufacturing technology field of the electric cap that particularly detonates interlocking voltage stabilizing digital display exploder.Be applicable to methane, coal-dust explosion and the detonate blasting site of electric cap of other engineering.
Background technology
Employed various types of exploders have had very big improvement and renewal technically in quick-fried ore deposit and engineering explosion at present.More advanced product has adopted digital panel meter to detect the detonator network, adopts stable-pressure device with technology such as prevent that electric capacity from overcharging, but also exists weak point:
1, digital panel meter uses a battery separately, or uses the battery of exploder simultaneously.Adopt the transistor electronic switch to finish auto-switch function.It is big that its major defect wastes electric current exactly, both still had the current drain of 1mA under obsolete situation.Just the electric energy of battery was exhausted substantially the battery of having to frequently change generally speaking less than one month.This not only wastes also contaminated environment of battery.2, owing in the explosion environment, contain explosion gas such as methane, coal dust in the air, there have slightly as producers' operation to be improper, and accident will create greater casualties.3, exploder in use because high-tension current impacts, often has phenomenons such as the transistor of burning, and the utilization rate of exploder is descended, and causes in the shot firing operation quick-friedly through constant error, gives to use with maintenance and all causes very big difficulty.
Summary of the invention
The purpose of this utility model is that a kind of interlocking voltage stabilizing digital display exploder that is used for detonating capsule is provided.
The utility model is achieved by the following technical solution:
1, adopts the digital panel meter of not power consumption.It is made up of battery, automatic relay switch, digital panel meter, calibrating terminal.In design the transistor Automatic Electronic Switch in the existing digital panel meter is changed into automatic relay switch.It is by calibrating terminal X
1, X
2Transistor V
1, V
2, V
3Relay K
1And contact K
1-1, K
1-2Form (seeing Fig. 1, Fig. 2).
There are three kinds of duties in this digitizing tablet.Its operation principle is:
(1) when not measuring the detonator network, because detonator network test terminal X
1, X
2Do not insert the detonator network, test point X
1End is through triode V
3PN junction, resistance R
2Draw and be high level, capacitor C
1Meet X
1End also is a high level, and the other end is through triode V
1PN junction draw and be low level, triode V
1End V
2Also and then end triode V
3Put high level because of base resistance and also end, relay K
1Not adhesive, its normally opened contact K
1-1Be in release conditions, battery to the digital panel meter power supply, do not work by digital panel meter.
(2) at calibrating terminal X
1, X
2When inserting the detonator network, test point X
1Drawn by the detonator network to be low level, triode V1 still is in cut-off state, V
2Also end.And test point X
1Low level, through resistance R
2Make triode V
3Positive bias and conducting, relay K
1Adhesive, normally opened contact K
1-1Closure, battery is powered to digital panel meter.Simultaneously, another normally opened contact K
1-2Also closed, the test lead IK of detonator network insertion digital panel meter
+And IK, digital panel meter is shown test results.
(3) during EOT, because the detonator network breaks away from calibrating terminal, test point X
1Revert to high level.This high level is through capacitor C
1Trigger triode V
1Conducting, thereby triode V
2Also and then conducting makes triode V then
3Base stage instead end relay K partially
1Discharge normally opened contact K
1-1Disconnect, digital panel meter quits work, simultaneously another normally opened contact K
1-2Also disconnect, disconnect test loop.Owing to adopted relay, can control power supply and two loops of test simultaneously, its contact does not have electric current to flow through in the circuit when disconnecting, so standby current is almost nil.Thereby solved the problem that digital panel meter wastes.
2, form control circuit with one or several tongue tubes and relay.Control the power supply of complete machine with control circuit, to realize the controlling organization (see figure 3) of multiple spot interlocking, many people interlocking.Its operation principle is:
Each tongue tube must be controlled by corresponding magnetic element, has only as tongue tube n
1, n
2When being opened by magnetic element simultaneously, could handle exploder and carry out bursting work.
Just many people such as the person of blowing out approve the ignition condition.Blow out security official, gas detection person, above-mentioned everyone respectively has a magnetic element key, opens this exploder jointly and just can finish bursting work, to stop the generation of accident can blow out the time when thinking simultaneously.
3, between the high-voltage output end of exploder and high-voltage capacitance, be connected in series a protective resistance R
b(see figure 4).Its operation principle is:
By high frequency transformer T
1The high pressure of output boosts through voltage doubling rectifing circuit, obtains a kilovolt above high pressure.This high pressure is through protective resistance R
bCurrent limliting is to high-voltage capacitor charging.During shot firing operation, it is put an electric current and flows back to negative pole through the detonator network by the positive pole of electric capacity.And protective resistance R
bPlayed preventing to blow out the effect of rush of current major loop, thereby protected major loop, reduced the fault rate of exploder.The utility model has the advantages that not power consumption of digital panel meter has many people interlocked control mechanism, security performance height.Have protective resistance, protection major loop, reduce the fault rate of exploder greatly.
