NON-ELECTRICAL MEANS OF INITIATION (OPTIONS) Russian patent published in 2023 - IPC F42C19/08 F42B3/10 F42D1/04 F42D3/04 

FIELD: initiation.

SUBSTANCE: the invention relates to safe means of initiation, can be used as a small-sized, non-electrical means of initiation during blasting operations for civil purposes, such as construction, group detonation systems in the mining and oil and gas industries. In the first option the non-electric initiation means consists of a housing 1 made in the form of a cup with a variable wall thickness in cross section, the bottom of which contacts the output BB hitch 8, an intermediate hitch 7 is located between the output hitch 8 and the initiating hitch 6. The wave igniter element 4 is made in the form of a waveguide, equipped with an internal hollow element 5 and fixed in a part of the housing, with a smaller wall thickness in cross section, with an elastic dielectric nozzle 3. A dielectric gasket 2 is located between the end of the wave igniter element 4 and the initiating hitch 6. In the second option, the non-electric initiation means consists of a housing made in the form of an initiating part having a smaller wall thickness in the section where the wave igniter element is located, equipped with an internal hollow element and fixed with an elastic dielectric nozzle. In the lower part of the housing, made in the form of a cup, there is an output BB hitch bordering the bottom of the base, the initiating BB hitch and the intermediate BB hitch that are in contact with them.

EFFECT: ensuring explosion safety by eliminating the possibility of triggering from the discharge of static electricity.
