Description
Technical field
The utility model relates to a kind of safety detection device for field construction in-site measurement electric cap resistance.
Background technology
In perforation construction, whether electric cap needs to detect detonator bridge silk resistance before going into the well normal, to improve reliability and construction one-time success rate.At present, larger for its volume of safety device of job site test detonator, quality is heavier, be not easy to carry and deposit, while measuring electric cap installation and removal all more loaded down with trivial details, increased workmen's burden.
Summary of the invention
The purpose of this utility model is exactly the problem existing for existing electric cap checkout gear, provides that a kind of volume is little, quality is light, easy to carry and store, mounts and dismounts process simple while detecting electric cap, and safe and reliable electric cap safety detection device.
This device is comprised of detonator container and instrumentation two parts, wherein instrumentation comprises power supply, measures gauge outfit, measures test pencil and switch, it is characterized in that: detonator container comprises buffering aluminum hull, steel bushing, steel drum and pressure cap, steel drum is the sealing staving that top is provided with through hole, pressure cap is provided with measured hole and conductive contact, after pressure cap is threaded with steel drum through hole projection, the through hole of the downward square impact steel drum of conductive contact; Steel bushing is " U " type structure, and steel bushing wall is provided with relief hole, and steel bushing top open part is connected in steel drum through hole; Buffering aluminum hull is " U " type structure of pegging graft and coordinating with electric cap, and buffering aluminum hull top open part is connected to the opening part of cylinder sleeve; Between steel bushing and buffering aluminum hull, leave gap.
Such scheme also comprises: instrumentation also comprises current-limiting resistance, static discharger and voltage limitator.
Instrumentation also comprises constant-current source.
Such scheme further comprises: in the cavity between steel drum and steel bushing, fill buffering sand.
Steel drum is the horizontal steel cylinder that bearing capacity is very strong.
Device of the present utility model; the one, the distortion by aluminum hull after electric cap accidental explosion absorbs explosion energy; the 2nd, by the pressure release of carrying out of the steel bushing protectiveness with relief hole; the 3rd, at the steel bushing with relief hole, be surrounded by buffering outward husky; again absorb the energy that blasting cap detonation produces, the 4th, outermost layer is the horizontal steel cylinder that bearing capacity is very strong, not only firm reliable; and changed electric cap accidental explosion and impacted wave line of propagation, protection personnel preserve from.This device volume is little, quality is gently easy to carry.Its instrumentation, the one, by current-limiting resistance and constant-current source Limited Current, guarantee that electric current is controlled in detonator safe current all the time, the 2nd, the voltage by voltage limitator control action on detonator, prevent that external voltage from impacting, the 3rd, by static discharger, guarantee that all the time measuring instrument is without static, guarantee in measuring process safe and reliable.
This measurement device bridge wire of electric detonator break-make and resistance easy and simple to handle, efficiency is high, has stopped to injure because measuring accidental explosion in electric cap process operating personnel's accident, for staff provides safely powerful guarantee.
Accompanying drawing explanation
Fig. 1 is the detonator structure of container schematic diagram of a kind of typical embodiment of the utility model,
Fig. 2 is the circuit diagram of instrumentation part.
In figure:
1-pressure cap, 2-steel drum, 3-aluminum hull, 4-steel bushing, 5-measured hole, 6-conductive contact.
7-power supply, 8-static discharger, 9-voltage limitator, 10-measurement gauge outfit, 11-measurement test pencil, 12-switch, 13-current-limiting resistance, 14-constant-current source.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, be described in detail.
Embodiment 1, with reference to accompanying drawing 1 and accompanying drawing 2, the electric cap that will measure is put into aluminum hull 3, cover tightly after pressure cap, conductive contact 6 is connected with electric cap positive pole, and measured hole 5 is inserted in one end of the measurement test pencil 11 of instrumentation, measures the other end and horizontal steel drum 2 housing contacts of test pencil 11, press switch 12, measure gauge outfit 10 and show that numeral can detect electric cap resistance.In measuring process, by current-limiting resistance 13 and constant-current source 14, to control all the time output current be 5 milliamperes to instrumentation, is far smaller than detonator safe current.Voltage by voltage limitator 9 guarantee effects on detonator is always 0.2v, can prevent the impact of external voltage.By static discharger 8, guarantee all the time not static electrification of instrumentation, guarantee the safety in measuring process.Even if because measuring in electric cap process, electric cap accidental explosion, the energy that the aluminum hull 3 absorption portion blasting cap detonations that now contact with detonator produce, by the steel bushing 4 with relief hole, remaining ability is discharged in horizontal steel drum 2, the remaining ability of the husky absorption of buffering is laterally housed in steel drum, and has changed blast impulse wave line of propagation.Stopped because accidental explosion in measurement electric cap process injures operating personnel's accident, for staff provides safely powerful guarantee.
