Abstract
The utility model relates to a civil explosive material used for detonating tube detonation network operation, in particular to a blasting cap used for a detonating tube detonation system. The blasting cap is characterized in that the blasting cap comprises a casing, priming charge, a rubber bayonet plug, a detonating tube and a delaying part, wherein the casing is a long tubular body with a corrugated closed end, the priming charge, the delaying part and the detonating tube are sequentially fixed at the bottom of the inner layer of the casing, the detonating tube is connected with a primer via the rubber bayonet plug and extends out of the casing from the inside of the casing, and the upper portion of the rubber bayonet plug extends out of the casing to be sleeved onto the outer wall of the detonating tube. The blasting cap can increase reliability and safety of detonating network and realize delaying detonation.
Description
Technical field
The industrial explosive material that the utility model uses when relating to a kind of detonator initiation net operation, particularly a kind of powder squib that is used for the detonator detonation train.
Background technology
Detonator propagation of explosion networking commonly used mainly contains two kinds of forms, and the first is made up of detonator outside detonator in the hole and the hole.When implementing mine and engineering explosion, carry out the extension of earth network and play detonator in the blast hole as lead with detonator outside the hole.But, because the explosion power of Nonel detonator is bigger, in the propagation of explosion process, destroy the networking easily, produce the demolition effect that slungshot then directly influences the networking during as the propagation of explosion blasting cap detonation, influence the reliability of engineering explosion, also have the process safe hidden danger of arranging net simultaneously.
It two is to carry out the networking by the plug-connected type contiguous block to connect, the plastics contiguous block comprise a propagation of explosion passage and more than two by the propagation of explosion passage, shock wave energy transmits by the propagation of explosion passage, pass to one or more plastic detonating tube, and these plastic detonating tubes are detonated, thereby ignite the detonator that is assemblied in the detonator other end, the use of propagation of explosion contiguous block can improve the security of blasting network.Its shortcoming is to realize the propagation of explosion of delaying, and range of application is restricted.
Summary of the invention
The purpose of this utility model is to provide a kind of powder squib that is used for the detonator detonation train, and it can improve the reliability and the security of detonator blasting circuit, realizes the extension propagation of explosion.
Technical purpose of the present utility model is achieved in that a kind of powder squib that is used for the detonator detonation train, it is characterized in that: it comprises shell, ignition charge, rubber bayonet socket plug, detonator, extension part; Shell is that an end has the elongated tubular body that wave closes up, shell internal layer bottom is fixing point gunpowder, extension part, detonator successively, by rubber bayonet socket plug and ignitron links together and stretch to outside the shell in shell, rubber bayonet socket part beyond the Great Wall extends to outside the shell, is socketed on the detonator outer wall.
It is the six lobe impressions of 0.3mm～0.1mm that described tube shell bottom has thickness.
Described ignition charge is a kind of high-energy igniter charge.
Peg graft with the plastics contiguous block in described powder squib bottom, any end of plastics contiguous block is connected with the detonator of another booster of carrying out the coffin upon burial, and a plurality of detonators and plastics contiguous block connect to form non-electric blasting networking.
Characteristics of the present utility model are: it is simple in structure, the reliability height, security is good, shock wave after the powder squib blast is by one or more plastic detonating tube of passing to of plug-connected type contiguous block safety, and make be connected the plastics contiguous block by the plastic detonating tube of propagation of explosion end by reliable initiation, thereby realized the reliable extension propagation of explosion of powder squib to many detonators.
Description of drawings
Below in conjunction with the embodiment accompanying drawing the utility model is described further.
Fig. 1 is an example structure schematic diagram of the present utility model;
Fig. 2 is the upward view of embodiment;
Fig. 3 is the utility model is connected the detonation train of forming the back with the plastics contiguous block a schematic diagram.
Among the figure: 1, shell; 2, ignition charge; 3, extension part; 4, rubber bayonet socket plug; 5, detonator; 6, powder squib; 7, plastics contiguous block.
The specific embodiment
Embodiment as shown in Figure 1 and Figure 2, it comprises shell 1, high-energy igniter charge 2, extension part 3, rubber bayonet socket plug 4, detonator 5.Be fixed in the shell 1 by ignition charge 2, extension part 3, detonator 5 carries out tight mouthful sealing and fixing by rubber bayonet socket plug 4, makes ignition charge 2, extension part 3 by in the safe and reliable shell that is fixed on sealing 1.
The shell 1 of embodiment detonator delayed denotation pipe can be made by metals such as copper, aluminium or its alloy, its length can be chosen between 10mm～100mm according to the needs of blasting energy, shell 1 internal diameter can be with reference to internal diameter and its supporting use of detonator shell, and the while is supporting with general rubber bayonet socket plug 4.Thickness is arranged at shell 1 bottom is the six lobe impressions of 0.3mm or 0.2mm or 0.1mm.Described ignition charge 2 is high-energy igniter charges commercial in the industry.
Installation step is: the high-energy igniter charge 2 and exerting pressure of packing into compresses, reinstall extension part 3, at the extension part 3 rubber bayonet socket plug 4 of packing into, in rubber bayonet socket plug 4, insert detonator 5, at last detonator 5 is connected shell 1 top by rubber bayonet socket plug 4, form powder squib 6.
During use as shown in Figure 3, powder squib 6 bottoms of embodiment and plastics contiguous block 7 are pegged graft, plastics contiguous block 7 any ends are connected with the detonator 5 of another booster 6 of carrying out the coffin upon burial, a plurality of detonators 5 and plastics contiguous block 7 connect to form non-electric blasting networking, it can form various non-electric blastings networking by plastics leads such as threeway, four-way, five-ways, using method is simple, and network connects flexibly, can be applied in all kinds of blasting engineerings.
During work, when detonator 5 reaches powder squib 6 with shock wave, the extension body that ignites, extension body burning causing ignition charge detonation, the shock wave initiation that the ignition charge detonation produces is assemblied in the detonator 5 that is no less than in the contiguous block.After the effect, the shock wave that high-energy igniter charge 2 produces is washed shell 1 bottom open, but body itself is still intact, and its energy is enough to ignite detonator 5 but can destroy network.The utility model compared with prior art has advantages such as time-delay is accurate, propagation of explosion is reliable, the network connection is easy, safe in utilization.
