AI Technical Summary
When the temperature of traditional fire-proof roller shutter doors exceeds their heat-resistant temperature, the fire will continue to cause losses and cannot be automatically extinguished.
An inorganic cloth fire-proof roller shutter door is designed. By setting a fire-extinguishing hose in the roller shutter door and connecting it with the fire water pipe, it uses high-temperature fused plastic snaps and leakage-blocking rings to automatically spray water flow to extinguish the flame.
The automatic fire extinguishing effect when the fire spreads is achieved, the fire resistance of the fire-proof roller shutter door is enhanced, and the use of inorganic cloth materials makes it light and low-cost.

They are composed of curtain plates, rollers, motors, guide rails, brackets, protective covers and control mechanisms, which can block the spread of fire in case of fire.
[0003] Traditional fire shutter doors can only block flames for a certain period of time. When the temperature exceeds the heat resistance temperature of the fire shutter doors, the fire will continue to cause damage. Now we need a fire shutter door that can automatically extinguish fire to further control the fire. Summary of the invention

[0014] Therefore, the present invention adopts the above-mentioned inorganic fabric fireproof shutter door, which has the following beneficial effects: (1) The fire shutter door is provided with a fire extinguishing hose, which is connected to a fire hose. When the fire spreads to the fire shutter door, the high temperature melts the plastic buckle, causing the leak-proof collar to separate from the surface of the fire extinguishing hose, exposing the spray hole to extinguish the flame, thus achieving the effect of automatic fire extinguishing. (2) Using inorganic cloth as the material of rolling shutter doors makes them lighter and less expensive; (3) Can be used in large-span scenarios.
