Description

TECHNICAL FIELD

[0002] Fire fighting automatic sprinkling, i.e., automatic water spraying fire extinguishing system, is a fire-fighting facility that can automatically spray water to extinguish fire when fire occurs. Its components include sprinkler, which has heat-sensitive glass ball inside, filled with specific liquid. Common red glass ball sprinkler operates at 68℃, green at 93℃, etc. Different colors represent different trigger temperatures. In the early stage of fire, the temperature of the fire site rises continuously. When the temperature rises to the operating temperature of the heat-sensitive glass ball of the sprinkler, the glass ball breaks or melts off. At this time, the sprinkler starts to spray water to extinguish fire. The heat-sensitive glass ball can only detect the fire below the sprinkler, and the detection range is narrow. Because the temperature distribution of the fire site is uneven, the fire size is different, and the small detection range can cause the sprinkler to fail to trigger water spraying in time. Therefore, we propose a kind of fire nozzle that can automatically spray water. SUMMARY
