CONTACT OR CONTACTLESS, OR MIXED TYPE BLASTING DEVICE (VERSIONS) Russian patent published in 2016 - IPC F42C13/00 

FIELD: blasting operations.

SUBSTANCE: invention relates to blasting operations, to initiation devices. Contact blasting device, including power supply installed inside housing, blasting mechanism and electronics unit, is characterized by that housing comprises set of seats and guides for launching ammunition rigidly fixed on common base, and in electronics unit additionally introduced objects in affected area location determining device, signal receiver, signal decoder, identification signals contact and contactless encoding unit for PA blasting, encoded and incoming signals conformity comparator unit, explosion signal delay unit, ignition device, applied is conventional or fibre-optic cable. Device is also characterized by fact that electronics unit includes spark plug and/or explosion initiation mechanical device. Contactless blasting device, including power supply installed inside housing, blasting mechanism and electronics unit is characterized by, that housing comprises set of seats and guides for launching ammunition rigidly fixed on common base, and made with possibility of actuation from built-in microphone, breloque, TV panel, and electronics unit additionally includes signal receiver, signal decoder, encoded and incoming signals conformity comparator unit, explosion signal delay unit, ignition device. Device is characterized by fact that contactless explosion initiation device is used. Mixed type blasting device, including power supply installed inside housing, blasting mechanism and electronics unit, providing preliminary introduction of code signal, its reception and recognition and/or with possibility of using conventional or fibre-optic cable, is characterized by fact that, body is made in form of multiple use platform with set of seats and guides for PA launching rigidly fixed on platform, PA contains charge and ignition system, and electronics unit additionally includes signal receiver, signal decoder, encoded and incoming signals conformity comparator unit, explosion signal delay unit, ignition device. Device is characterized by fact that PA contains ignition device using spark plug, and/or mechanical, and/or contactless blasting initiation device.

EFFECT: invention allows to ensure increased safety when used in blasting designs of domestic and industrial use pyrotechnic articles.
