FIRE FIGHTING DEVICE WITH FIRE SPRINKLERS Russian patent published in 2017 - IPC B05B1/04 A62C31/02 A62C37/08 

FIELD: fire safety.

SUBSTANCE: device consists of a network of main and distribution pipelines, constantly filled with liquid fire extinguishing composition with fire sprinklers, a water supply source representing a water tank and a water intake system with a filter and a pump, and two automatic water feeders. The fire sprinkler comprises a body which is made in the form of a straight case with windows at its lateral surface. At one end of the straight case, facing towards the spray device, a partition is disposed. The spray device is designed as a socket formed by the part of spherical surface with thickness "s", in which radial slots are made. The socket is attached to the end surface of the case by means of at least two arcs, disposed along the conical surface, the upper part of which is fixed at the partition, and the socket is attached to the lower part, which is the part of the spherical surface, limited by the inner and outer hemispheres. The hemispheres center lies on the line connecting the straight case axes and the partition axis. On the outer side of the spherical surface at least three grooves are made, the axes of which are located on the radial lines with respect to the hemisphere. At least three throat holes are made in the peripheral part of the hemisphere, the centers of which lie in a plane parallel to the diametral plane of the hemisphere, which is perpendicular to the axis of the straight case. The axes of the throat holes intersect at a point lying on the axis of the straight case and form an acute angle with this axis in the plane of the drawing.

EFFECT: increased efficiency of fire extinguishing due to addition of quick-acting elements to the common circuit of the automatic fire-extinguishing system.
