Fireproof tank box with active fire extinguishing function

Abstract

The utility model provides a kind of fireproof tank box with active fire extinguishing function, effectively solve the existing fireproof tank box and need to trigger fire extinguishing mechanism by external detection signal, active fire extinguishing efficiency is poor, it is difficult to form effective isolation, too idealized problem;Its solution technical scheme is, including horizontal rectangle cylinder, rectangle cylinder is uniformly distributed with multiple fire extinguishing units;The fire extinguishing unit includes two interlocking arc-shaped plates, movable plate is hinged on rectangle cylinder cavity inner side wall by torsion spring, arc-shaped groove is set on the side of movable plate close to arc-shaped plate, and the middle part of arc-shaped groove is hinged between the outer side wall of arc-shaped plate by torsion spring;Arc-shaped plate inner side wall is provided with sodium hydroxide-rich fire extinguishing layer;The utility model structure is ingenious, can form multiple partitioned space in fireproof tank box chamber, can adapt to different specifications of wire, can be self-adapting clamped on wire, so that flame is very difficult to pass through tank box chamber, realize active fire extinguishing of wire cable.
