This technology is a fire-suppression blind featuring a roller that stores extinguishing fluid and is rotatably mounted within a frame fixed to a structure. When a motor rotates the roller to unroll the pouch-type flame-retardant member, the extinguishing fluid flows down through the member and is sprayed via nozzles on the bottom discharge rod.
Pilotis-style buildings have open first floors with columns and parking areas, which allow oxygen to enter from all sides during a fire. The chimney effect causes flames to spread rapidly up walls and into the building via stairwells, yet these areas often lack dedicated fire-suppression systems. Existing fire blinds, which roll up to prevent fire spread, only protect the screen itself from burning and fail to block or delay the spread of flames and smoke.
In this technology, a heat-shrinkable member at the bottom of the flame-retardant material contracts when heated, wrinkling the material and changing the spray angle of the attached nozzles to direct extinguishing fluid toward the most intense flames. When deployed, a bending member on the frame seals against the roller to prevent smoke from escaping through the top gap. Upon fire detection, a motor activates, and extinguishing fluid is continuously replenished via a supply pipe connected to the tubular rotating shaft. Applicable to first-floor parking areas of multi-unit housing and villas, commercial entrances, stairwells, and underground parking access points, this system acts as a water curtain to block fire paths, providing residents on upper floors with critical time to evacuate.
