DEVICE FOR SPRAYING LIQUIDS, IN PARTICULAR FOR FIRE PROTECTION SYSTEMS Russian patent published in 2022 - IPC A62C35/00 A62C31/00 B05B3/04 

FIELD: fire protection.

SUBSTANCE: invention relates to the field of fire protection systems. In particular, the invention relates to the field of fire protection systems especially suitable for mine galleries, tunnels, underpasses and enclosed spaces not only of a large size. Device (100) for spraying liquids, in particular for fire protection systems, contains first tubular dispensing element (10) adapted for connection to the main supply pipeline, second tubular spraying element (12) hydraulically connected to first tubular dispensing element (10) for spraying liquids into the surrounding space. Moreover, second tubular spraying element (12) is made with the possibility of being rotated, while device (100) contains a means for rotation of second tubular spraying element (12). Second tubular spraying element (12) contains first essentially rectilinear part (13), and it is adapted for being brought into rotation around axis (X) of rotation, which is essentially parallel to the axis of the longitudinal extension of essentially rectilinear part (13). The means for rotation of second tubular spraying element (12) contains turbine (30) fixed by a key on first essentially rectilinear part (13). The means for rotation of turbine (30) contains third tubular outlet element (19) connected to first tubular element (10) for redirection of liquid from first tubular element (10) to turbine (30). Second tubular spraying element (12) contains intermediate part (14), which passes from rectilinear part (13), and rectilinear end part (15), which passes from intermediate part (14). Intermediate part (14) is curved relatively to rectilinear part (13) so that the longitudinal axis of symmetry of rectilinear end part (15) forms an angle in the range of 0-45° with a plane essentially perpendicular to the direction of the extension of first essentially rectilinear part (13). Spraying head (16) is attached to rectilinear end part (15), adapted for formation of a jet of fluid (40) coming out of rectilinear end part (15), essentially fan-shaped, or conical, or arrow-shaped, wherein device (100) contains supporting frame (18), and second tubular element (12) is made with the possibility of rotation relatively to main supporting frame (18), while the device contains a means for reduction and/or limitation of friction installed between supporting frame (18) and first essentially rectilinear part (13) of second tubular element (12).

EFFECT: ensuring the distribution of properly sprayed liquids and/or fluids without the use of compressed air or gas.
