Problems solved by technology

At the same time, due to the high reliability of the blasting network in large-scale project blasting, however, the quality problems of some detonators, the irregular operation of construction personnel, and the harsh construction environment of some projects are likely to cause premature detonation of detonators and cause safety accidents
The premature detonation of the detonator will cause the explosion of the entire detonation network, which will cause a devastating blow to the entire project, causing heavy casualties and property losses

Embodiment 1

[0024] figure 2 That is the structural diagram of the explosive diode of the present invention, corresponding to the working conditions: A is used as the detonating end, B is used as the output end, the outer diameter of the shell is 6.8mm, the inner diameter of the input port is 6mm, and there is a positioning step at 12mm deep into the port, and then the inner diameter begins to gradually Reduced to 3mm, held to the corners. Put the detonating cord into the B end, go deep into the positioning step 2 inside the nozzle, and fix the detonating cord to the shell with a closing machine. Then put the booster Taian (density 0.88g / cm2) from the input end 3 ) to the positioning step of the input end, and finally put in the detonating cord, squeeze and fix it on the shell with a closing machine. Finally, put an iron sheet at the detonating cord at the output end B as a verification board. When the detonating cord at the output end detonates, a pit will be left on the iron sheet, wh...

Embodiment 2

[0026] according to image 3 Schematic diagram to make an explosive diode device with a positive and negative symmetrical structure. This structure is completely symmetrical, and it can conduct positive and stable explosion transmission and reverse reliable explosion prevention experiments at one time. Choose the iron shell, according to the attached image 3 As shown, assemble, now connect the detonating cord and rubber plug at the B end to the wall of the tube shell, then install it into Taian from the other section, and finally install the detonating cord. The entire charge structure is completely symmetrical, and then one end is selected as the detonating end, then the charge of the tube shell is used as the forward explosion transfer experiment, and the other tube shell is used as the reverse flameproof end, marked and detonated. The test was repeated 10 times, and the results showed that the one at the detonating end detonated normally, while the one at the flameproof e...

Embodiment 3

[0028] Such as Figure 4 As shown, make series explosive diodes, 10 rounds of explosive diodes are connected in series, and detonate from the positive direction A. The experiment found that the explosive diodes detonated sequentially. The results show that the explosive diode has a very stable forward transmission capability.

Abstract

The invention discloses an explosion diode based on a detonation wave corner effect, and belongs to the field of explosive materials. The explosion diode comprises a constraint shell, a detonator signal channel, a high explosive, an output signal channel and the like. The constraint shell is a special unequal-inner-diameter metal pipe shell with a corner. Openings are formed in the two ends of the constraint shell, an inlet of the input end is consistent with that of the output end, but the inner diameter of the input end is gradually decreased till a small inner diameter constant value is achieved, and the inner diameter of the output end is unchanged. According to the explosion diode, explosive pressing is not needed; the process is simple and safe; high operability is achieved; the quantity of the adopted explosive is small; field assembly and explosive charging can be achieved, and even modular field assembly production can be achieved; transportation safety is greatly improved; and meanwhile the explosion diode has a reverse explosion-resistant function, and huge denotation losses, caused by premature detonation, of a whole detonating network are avoided.

Description

technical field [0001] The invention belongs to the technical field of blasting equipment, and in particular relates to an explosive diode based on the detonation wave corner effect. Background technique [0002] The mining of mineral resources is closely related to the development of my country's industry. With the depletion of easy-to-mine resources, the mining industry is facing many thorny problems such as difficult mining and harsh environments. Moreover, considering the use of explosives to mine resources, the demand for detonators is also huge. . At the same time, due to the high reliability requirements of the blasting network for large-scale engineering blasting, however, the quality problems of some detonators, the irregular operation of construction personnel, and the harsh construction environment of some projects are likely to cause premature detonation of detonators and cause safety accidents. The premature detonation of the detonator will cause the explosion o...
