DEVICE FOR FIRE EXTINGUISHING AND FIRE-AND-EXPLOSION PREVENTION WITH FOAM OF LOW AND MEDIUM RATIO Russian patent published in 2019 - IPC A62C15/00 

FIELD: fire safety.

SUBSTANCE: invention relates to fire extinguishing and fire-and-explosion prevention equipment, namely to devices for combined extinguishing of large-scale fires of classes A and B and for fire-and-explosion prevention of air-mechanical combined foam of low and medium ratio. To achieve technical result, device for combined fire extinguishing and fire-and-explosion prevention with foam of low and medium ratio comprises two combined low- and medium-rate combination foam generators fixed on crossbar, comprising a body with a pack of average-size foam generation nets arranged inside the body, a foaming agent water solution nozzles unit arranged in front of the body on a pack of average-size foam generation nets, low-expansion foam formation barrel, pipeline of foaming agent water solution to nozzles and foam barrel of low ratio and means of connection of foam generator to pressure pipeline. Means for automated turns of crossarm with fixed on it foam generators in vertical and horizontal planes are made with possibility of their connection to remote control system and with possibility of remote control by remote control panel or radio signals of remote control system. Device for automated turns of crossarm with fixed on it foam generators in vertical plane is made in form of actuator, comprising linear drive and electric motor, and means of automated turns of crossarm with fixed on it foam generators in horizontal plane comprises gear transmission of rotation and electric motor.

EFFECT: increased efficiency of fire extinguishing and fire-and-explosion prevention due to increased range and uniformity of foam of medium and low ratio distribution by area of fire and increased safety of process of fire extinguishing and fire-and-explosion prevention in especially fire-and-explosion hazard objects.
