The baffle igniter is an explosion-proof igniter, and can convert detonation signals into flame signals so as to realize the detonation function. As shown in fig. 1, the conventional bulkhead igniter includes a detonation initiating unit, a bulkhead, a BPN ignition charge, and the like. After the external detonation signal reaches the external detonation action end face 01 of the partition igniter, the detonation unit 02 generates flame, the residual detonation signal continues to act on the detonation partition 03 and destroys the detonation partition 03 to realize energy attenuation, and the flame generated by the detonation unit 02 ignites the BPN ignition charge 04 to realize the function of detonating the initiating explosive.

However, the related art bulkhead igniter has the following problems:

First, current baffle igniter is as solitary ignition, is difficult to install on products such as less initiating explosive device, can't be applied to all kinds of products, and the suitability is relatively poor.

Second, when delayed detonation is desired, the end of the initiating explosive device that is adjacent to the BPN ignition charge is typically provided with a delay sequence, such as a delay charge or the like. However, the BPN ignition powder adopted by the existing partition igniter has the characteristics of high output and high heat, the strength of flame generated by the BPN ignition powder is high, the range is wide, a delay structure is easy to be directly destroyed, instantaneous detonation is caused, and the delay requirement cannot be met. Therefore, in the case of time delay requirement, the baffle igniter in the prior art has poor controllability and consistency, and certain product quality risk exists.

Detailed Description

The utility model will be better explained by the following detailed description of the embodiments with reference to the drawings.

Example 1

As shown in fig. 2, the present embodiment provides an explosion-proof type detonation device, which includes a partition plate 1, and a fire cap 2. Wherein, one end of baffle 1 is connected with initiating explosive device, and the inboard of the other end of baffle 1 sets up hood 2, and the outside of the other end of baffle 1 is used for receiving detonation signal 3.

The detonation principle of the explosion-proof detonation device of the embodiment is as follows: the detonation signal 3 outside is transmitted to the partition board 1 to attenuate energy, after the detonation signal 3 acts on the partition board 1, tearing-shaped fragments can be generated on the partition board 1 towards one end face of the fire cap 2, and the attenuated detonation energy or the tearing-shaped fragments generated by the partition board 1 can reliably ignite the fire cap to generate flame signals, so that initiation is realized. The embodiment can control the explosive quantity of the fire cap so as to adjust the intensity and the range of flame generation, thereby realizing the control of the detonation effect.

The explosion-proof type detonating device of the embodiment has the following advantages:

First, the detonating device of this embodiment is simple in structure, can be widely used in various products to can regard as a whole with initiating explosive device product.

Second, the initiating device of this embodiment adopts the cap to replace BPN ignition charge among the prior art, and the intensity of the flame that the cap produced is lower, and the scope is littleer, to the initiating explosive device that needs to delay with the gunpowder medicament, the initiating device of this embodiment can guarantee the completion of the time delay sequence of gunpowder medicament reliably, ensures the time delay precision.

Third, the priming device of this embodiment omits the priming unit and employs a lower cost cap than BPN ignition charge, with good economy and cost far lower than that of a bulkhead igniter.

In addition, the fire cap in the explosion-proof type detonating device has better sealing performance and lower hygroscopicity, so that the fire cap can be stored for a longer time. The BPN ignition powder used in the partition igniter in the prior art has poor sealing performance, and the BPN ignition powder contains nitrate, so that the partition igniter has good hygroscopicity, is easy to wet and is not easy to store. Therefore, the priming device of this embodiment has a longer shelf life, with a shelf life of greater than 20 years.

Preferably, the separator 1 in this embodiment is a steel plate, and the thickness of the separator 1 is preferably 3-5mm. In this embodiment, the steel plate may be a 45-gauge steel plate, a T10A steel plate, or the like. The fire cap 2 of the present embodiment is preferably a needle-punched fire cap. The thickness of the baffle plate in this embodiment is 3-5mm, which is thicker than the prior art, and is not destroyed under the action of the detonation signal, but the fire cap generates a flame signal by generating tearing-like fragments or by the rest of the detonation energy acting on the fire cap.

The side of the cap 2 parallel to the direction of transmission of the detonation signal 3 is denoted as a first side 21, and the side of the cap 2 perpendicular to the direction of transmission of the detonation signal 3 is denoted as a second side 22. The first side 21 and the partition board 1 may be adhered by adhesive, etc. and the second side 22 is in direct contact with the partition board 1, or the second side 22 is spaced from the partition board 1 by a distance of 1-2 mm.

In the present embodiment, the second side surface 22 and the partition plate 1 are arranged in different positional relationships according to the intensity of the detonation signal 3 from the outside. Specifically, when the intensity of the detonation signal 3 from the outside is weak, the second side 22 is preferably in direct contact with the partition board 1, so as to ensure that the flame signal can be generated by the fire cap 2. When the intensity of the detonation signal 3 is stronger, the second side surface 22 and the partition board 1 can be in direct contact, and can also have a distance of 1-2mm, and in the distance range, tearing-shaped fragments generated by the partition board 1 can still ensure to touch the fire cap 2 and enable the fire cap 2 to generate a flame signal.

In this embodiment, the shape and the closed state of the partition board 1 do not have a fixed requirement, one end of the partition board 1 receiving the detonation signal 3 may be a closed structure, and the fire cap may be wrapped in the closed structure or may be a semi-open structure, and only the condition that the fire cap and the detonation signal are respectively on two sides of the end surface of the partition board far away from the initiating explosive device is required.

In addition, in addition to causing the barrier to generate tearing-like fragments by the detonation signal to ignite the cap, as shown in fig. 3, the present embodiment may further provide a striker 4 and a washer 5 between the barrier 1 and the cap 2, the striker 4 including a striker body 41 and a needle tip 42.

The positions of the baffle plate, the firing pin and the fire cap are as follows: the two end faces of the gasket 5 are respectively in contact with the firing pin body 41 and the fire cap 2 in a fitting manner, the other end face of the firing pin body 41 is in contact with the partition board 1, the needle point 42 is in contact with the fire cap 2 in a fitting manner, the gasket 5 is used for supporting the firing pin 4, and the firing pin body 41 and the needle point 42 can be respectively in contact with the partition board 1 and the fire cap 2. In this way, under the action of the detonation signal 3, the tip 42 of the striker 4 can exert an action directly on the fire cap 2, so that the fire cap 2 stably generates a flame signal.

Preferably, the gasket 5 is a rubber ring. The striker 4 may be a steel member such as a 45-gauge steel plate, a T10A steel plate, or the like.

In fact, after repeated tests, no matter the fire cap is directly contacted with the partition board or has a certain distance with the partition board, or the firing pin and the gasket are arranged between the partition board and the fire cap, the success rate of detonation is stabilized to be more than 99.9%, and the stability of detonation is excellent.
