Description
Technical field
The present invention relates to a kind of priming system extension detection means, especially a kind of photoelectric type priming system extension time inspection
Survey device.
Background technology
Detonator is indispensable instrument in various engineering explosions, and it is quick-fried that its accuracy for delaying the time is directly connected to engineering
Broken safety and quality, so needing to do sampling Detection to the extension time of every batch of delay detonator during detonator production.Mesh
Before, most detonator production producers are that fire element, delay element, basal detonator are assembled into finished product and are detected, this
Sample will use substantial amounts of detonator, and labour intensity is big, and noise is big, and testing cost is high, security risk is big.
In addition, detecting that the extension time mostly uses piezoelectric transducer or probe at present.Aborning, an induced detonation is mostly done by producer
Case, in centre position installation piezoelectric transducer, there is very big difference in the time of delaying of such centre position and surrounding.Use probe
Detection second amount, although high precision, but efficiency is low, and labour intensity is big.
The content of the invention
The purpose of the present invention, aiming at the deficiency existing for prior art, and provides a kind of photoelectric type priming system and delays
The technical scheme of time detection device, the program receives photosignal using photosensitive tube, and controls detonation velocity meter to stop counting, without
Detonator is installed, is operated simply, without security risk, accuracy of detection high, low cost, noiselessness.
This programme is achieved by the following technical measures：
A kind of photoelectric type priming system extension time detection device, includes lighttight detection case, detonation velocity meter, is arranged on inspection

As the preferred of this programme：Power interface is provided with the side wall of detection case.
The beneficial effect of this programme can be learnt according to the narration to such scheme, highly sensitive due to employing in this scenario
Degree photosensitive tube stops signal gathering light, makes detonation velocity meter（Such as the multi-functional detonation velocity meter of BC-1 types）Light and stop count, delayed
Time.The summation of the time equal to fire element, delay element and basal detonator action time of delaying of delay detonator, and basic thunder
The action time of pipe be in Microsecond grade, it is negligible, thus delay detonator the extension time be approximately equal to fire element act on when
Between with delay element delay time sum, so fire element and delay element are assembled, it is possible to utilization the invention device
The detonator delay time is detected, reaching not card detonator can also detect the extension time, both cost-effective, reduce labor intensity, and
Accuracy of detection, noiselessness, without security risk, energy-conserving and environment-protective can be improved.
As can be seen here, the present invention compared with prior art, with substantive distinguishing features and progress, its beneficial effect implemented
It is obvious.
