FLOOR-MOUNTED GAS-POWDER FIRE EXTINGUISHING DEVICE Russian patent published in 2024 - IPC A62C35/02 A62C35/13 A62C13/02 

FIELD: fire-fighting equipment.

SUBSTANCE: invention relates to the field of fire extinguishing, namely to the floor-mounted gas-powder fire extinguishing device containing the frame supported on the floor of the room, inside the frame there is a vertically located cylinder with a powder substance and two vertically located high-pressure cylinders with gas, each of which is interconnected through a separate shut-off-start-up unit with an outlet common for both high-pressure cylinders, which is interconnected with the inlet of the cylinder with powder substance, sprayed powder outlet branch pipe of which is connected to the upper part of the cylinder with powder substance and is brought out through the upper part of the frame or the sprayed powder outlet branch pipe of which is connected to the bottom part of the balloon with the powder substance and is brought out through the lower part of the frame, at that, in the lower part of the frame there is a platform for installation of a cylinder with a powder substance on it, each shut-off-start-up unit is made with a movable element used to pierce the membrane, which isolates the cavity of the cylinder with the powder substance from the external medium, and with pyrotechnic element for formation of gas pressure and displacement of movable element towards membrane breakthrough, and wires of pyrotechnic elements are connected to communication unit used for communication with power supply, at that, the frame is made of four posts of C-shaped section, in the lower part, connected to each other by a platform with a lodgement for a cylinder with a powder substance, and two crossbars in the form of plates spaced apart along the height of the side walls, at the upper of which on the post there are elements of connection with clamps, posts on lateral sides are interconnected by spaced apart on height lower and upper crossbars, wherein upper crossbars are interconnected by upper additional crossbar, and lower crossbars are connected to each other by lower additional crossbar, on the platform for the cylinder with the powder substance between the posts carrying the crossbars, a vertically oriented post is fixed, at the level above the platform for the cylinder with the powder substance, the bearing elements of the switching unit fastening, high-pressure gas cylinders are located outside the frame, their lower part is lowered and rests against the lodgements on the lower additional crossbar for laying high-pressure cylinders, which are attached by clamps to the middle part of the upper additional crossbar and to the elements for connection with clamps on the posts, in the upper part of the frame the posts are connected to the cover, part of which is located above the high-pressure gas cylinders.

EFFECT: described is a floor-mounted gas-powder fire extinguishing device.
