Embodiment Construction

[0022] exist figure 1 In , a system 2 is shown having a detonating device 4 connected to a powder train 6 . A charge train 6, such as a detonating cord, extends from the detonating device 4 towards the charge or other combustible material. As shown in the figure, the detonating device 4 is configured to move from an out-of-line orientation 8 to an in-line orientation 10 in which activation of the detonating device 4 does not result in ignition of the explosive system 6, and in an in-line orientation 10 in Activation of the detonator 4 allows ignition of the explosive train 6 . The detonating device 4 includes an electronic switch 12 for receiving a signal from a remote location, which allows the repositioning of the detonating device 4 without physical manipulation by the operator and just before the detonating device 4 is activated. Thus, the detonating device 4 may remain in the off-line orientation 8 until the detonating device 4 is in a predetermined position and ready t...

Abstract

A detonator device includes a mechanism for shifting between an out-of-line orientation, wherein initiation of a detonator does not result in initiation of the explosive train, and an in-line orientation, wherein initiation of the detonator results in initiation of the explosive train.

Description

technical field [0001] The present invention relates to a safety device, and more particularly to a method and apparatus for activating a train of explosives to detonate the explosives, for example using a perforating gun. Background technique [0002] Many known gunpowders require significant shock, heat, force, or other stimulus to detonate, often referred to as secondary powders. Accordingly, a powder system, which typically includes a detonator and an intermediate, is typically used to detonate these powders efficiently. In order to provide ease and convenience of use, the detonator is usually constructed using an easily detonated priming charge. [0003] In the case of easy and convenient detonator ignition, precautions are taken to prevent accidental activation of the detonator or interruption of the powder train extending to the powder. [0004] The first known method is to physically isolate the detonator from the rest of the powder train until the moment detonatio...
