SCANNING FLAME DETECTOR WITH A FUNCTION OF DETERMINING THE ANGULAR COORDINATE OF THE FIRE SOURCE Russian patent published in 2021 - IPC A62C3/00 G08B25/00 

FIELD: firefighting.

SUBSTANCE: scanning flame detector with a function of determining the angular coordinate of the fire source relates to firefighting flame detectors and is intended for detecting fire sources by ultraviolet and/or infrared radiation of the flame and determining the angular coordinates thereof. The detector has a body, on the face part whereof a window is made in the form of an optically transparent side surface of a cylinder with an arc length limited by the maximum viewing angle of the detector in the horizontal plane. An emission receiver is installed near the central axis of the body, a rotary scanning apparatus constituting a rotating cylindrical slit obturator is installed outside of the window, a slit gap is made in the lateral and the lower parts of the obturator, ensuring illumination of the sensitive element. A sectoral cut is made in the obturator opposite the slit gap, following the form of the window. The aperture angle of the sectoral cut is equal to the maximum viewing angle of the sensitive element.

EFFECT: creation of a scanning flame detector with a function of determining the angular coordinate of the fire source.
