DRENCHER Russian patent published in 2018 - IPC B05B1/26 A62C31/02 

FIELD: fire safety.

SUBSTANCE: invention relates to firefighting equipment. Drencher contains a housing and a spraying device with a spraying element. Housing is designed as a central sleeve with an external hexagon and an internal cylindrical surfaces. Spraying element is made as a sleeve, to which by means of arcs arranged along a conical surface, an outlet is formed, which is part of the spherical surface bounded by the inner and the outer hemispheres. At the lateral surface of the central sleeve with the external hexagonal and the internal cylindrical surfaces there are at least three throttle openings inclined to the outlet. Cross section of the arcs located along the conical surface and connecting the sleeve with the outlet is made of a profiled shape, for example helical, to increase the effect of finely dispersed spraying of the foamer solution. At least three throttle openings inclined to the outlet are made with a screw thread. Direction of the screw thread in the throttle openings is made with alternating left and right directions. To the end surface of the sleeve by means of at least three inclined rods located in spaces between the arcs, a truncated diffuser is attached by means of at least three horizontal rods connecting it with the outlet. Truncated diffuser is made as a shell formed by the conical surface of the truncated cone, the smaller diameter of which is connected to the horizontal rods, and the larger diameter is equal to the diameter of the outlet section of the diffuser.

EFFECT: technical result of the invention is to increase the effectiveness of fire extinguishing.
