Abstract
The utility model discloses a two-direction delay blasting cartridge, which applies the engineering blasting explosion propagation network. The two-direction delay blasting cartridge is formed by arranging a cartridge shell, a bayonet plug, water resistant igniting powder, high-energy igniting powder and a delay body in sequence. The utility model is characterized in that the two-direction delay blasting cartridge can realize two-direction delay blasting; when the forward explosion propagation fails, the reverse blasting action can be utilized. The utility model has high action reliability, convenient use, simultaneously no high explosive and priming utilization, and high safety performance.
Description
The utility model relates to a kind of priming system, particularly a kind of two-way extension detonating relay that is applied to the propagation of explosion network.
In existing propagation of explosion network, generally adopt delay detonator as the propagation of explosion connector, with the purpose that reaches extension and realize short-delay blasting, be characterized in containing high explosive and priming in the detonator, brisance is big, and human body and propagation of explosion network are had infringement, security is relatively poor, simultaneously, the propagation of explosion of detonator in network is unidirectional, and the detonation of a direction can not make its effect, this detonator is with regard to misfire, cause residually, it is very difficult technically to handle residual detonator, also very dangerous.
The purpose of this utility model is to provide a kind of security good, the easy to use and two-way extension detonating relay of energy beidirectional.
The technical solution that the utility model purpose realizes is: a kind of two-way extension detonating relay, it is characterized in that it is made of shell, bayonet socket plug, water-fast ignition charge, high-energy igniter charge, extension body, the extension body is positioned at the middle part of shell, and its both sides set gradually high-energy igniter charge, water-fast ignition charge, bayonet socket plug respectively.
Principle of the present utility model is: after the detonator that is connected in the arbitrary end of the utility model is excited, water-fast ignition charge, high-energy igniter charge ignite, and make the effect of extension body, through sometime at interval after, the high-energy igniter charge and the water-fast ignition charge of the output flame ignition other end of extension body, water-fast ignition charge releases energy with the reduced blast form, thereby excites the detonator of the other end, has so just realized delaying to continue quick-fried function.
The utility model compared with prior art, its remarkable advantage is: 1, function reliability improves.Because but the utility model two-way function during positive direction effect failure, can rely on detonative action in the other direction, the misfire rate is low, and residual quantity is minimum; 2, security is good.Do not adopt high explosive and priming in the utility model, brisance is very little, does the time spent not produce explosion fragment, can not produce infringement to human body and blasting network, 3, easy to use.Because the utility model either direction all can act on,, can improve operating speed so need not distinguish direction when being connected with blasting network.
Accompanying drawing is a kind of structural representation of the present utility model.
Below in conjunction with accompanying drawing embodiment of the present utility model is described.
Embodiment.In conjunction with the accompanying drawings, two-way extension detonating relay of the present utility model is made of shell (1), bayonet socket plug (2.2 '), water-fast ignition charge (3.3 '), high-energy igniter charge (4.4 '), extension body (5), shell (1) is cylindrical, can be made by materials such as copper, aluminium, shell (1) middle part is provided with the plumbous zinc extension of standard body.In extension body (5) both sides, set gradually high-energy igniter charge (4.4 ') and the water-fast ignition charge of standard (3.3 ') respectively, two kinds of ignition charges are placed in the strengthening cap (7.7 ') respectively, at shell (1) two ends, bayonet socket plug (2.2 ') is set, the bayonet socket plug is made by the high pressure PEF, small cylindrical opening (6.6 ') is set, so that being connected of the utility model and detonator (8.8 ') on it respectively.High-energy igniter charge adopts CuO, Al, Pb
3O
4The mixture that constitutes.Delay time of the present utility model can be determined according to needs, generally fix on about 100ms.
Claims (2)
1, a kind of two-way extension detonating relay, it is characterized in that it is made of shell (1), bayonet socket plug (2.2 '), water-fast ignition charge (3.3 '), high-energy igniter charge (4.4 '), extension body (5), middle part in shell (1), extension body (5) is set, in extension body (5) both sides, set gradually high-energy igniter charge (4.4 '), water-fast ignition charge (3.3 '), bayonet socket plug (2.2 ') respectively.
