SENSOR OF SHOCK WAVE (VERSIONS) Russian patent published in 2013 - IPC A62C37/00 

FIELD: fire-prevention facilities.

SUBSTANCE: invention relates to fire-fighting equipment and can be used to activate remotely the agitating system of the fire fighting plant off-line of continuous control of fire and explosion hazard state of the controlled area in case of pulse pressure generated in the air by explosion source of shock wave, particularly in the underground workings of coal mines, at enterprises of oil-refining industry, etc. The sensor of shock wave (versions) comprises a housing with a lid, a power trigger element in the form of a plate hingedly connected on it, a spring made with the ability to reinstall one of the hitches. The means that triggers an electrical impulse is a magnetic system (version 1) or is made in the form of an accumulator battery (version 2).

EFFECT: sensor design, which provides the dynamic factor (shock wave) transformation in a remote, inaccessible and rarely visited controlled area into an electrical impulse, which effects remotely on the triggering device of the remote means of fire and explosion suppression, greatly increases the possibility of its rapid response, anticipating coming of the shock wave to it, enables to achieve reliably the functional result, with high speed, stand-alone, with the exclusion of the human factor and increase the reliability of the triggering device of fire and explosion suppression at a low cost for operation.
