Abstract

Disclosed is an emergency rescue shaped charge cutting device with life detection function including a life detection device and a shaped charge cutting device body. The life detection device body is arranged on the inner or outer side of the shaped charge cutting device body. The shaped charge cutting device body includes a protective cover, a shaped charge cutting rope and a fuze system. The shaped charge cutting rope is embedded in the front side of the protective cover, and the detonating end of the fuze system penetrates into the interior of the protective cover from the rear side of the protective cover to be connected to the shaped charge cutting rope. Accordingly, the life detection device may be combined with the shaped charge cutting device to detect living beings and achieve precise blasting, thereby coordinating operation of the two devices and improving rescue efficiency.

Claims (10)
