3 The operations of the triggering device can be classified into two types, namely manual triggering and automatic triggering, when a fire occurs.
1. Automatic triggering When a fire occurs, the fire ignites the safety fuses with the steel wires.
The safety fuses are quickly exhausted. When the safety fuses with the steel wires only have the steel wires left, the diameter is greatly reduced. At this time, the gap between the bracket and the steel wires increase. By the gravity effect of the slats, the pulling force is far greater than the friction force between the bracket and the steel wire, and then the steel wires are automatic extracted from the bracket. Without the pulling force, the slats automatically drop off from the hooks of the rear-end fixed guide rail and droops down automatically, thereby closing the fire field.
2. Manual triggering When a fire just occurs and does not reach and ignite the safety fuse, the handle can be manually pulled down. When the handle is pulled down, the bracket releases, and the safety fuses with the steel wires are automatically extracted from the bracket by the effect of the pulling force, so that the slats drop off, droop and close the tunnel.
Further, the slats are all made from high-temperature resistant, fireproof and flame-retarding materials.
Further, the high-temperature resistant, fireproof and flame-retarding materials are alkali-free glass fiber cloth.
The content of the alkali-free glass fiber R20 is less than 0.8%, and the glass fiber is an alumina borosilicate element. The alkali-free glass fiber features high chemical stability, electric insulation and strength. The alkali-free glass fiber cloth is fireproof cloth formed by treatment with high-temperature-resistant, non-toxic and fireproof glue coatings. The alkali-free glass fiber cloth is the optimal fireproof material for manufacturing the fireproof protector, flame-retarding and heat-insulating materials and fireproof roller shutters. The

The quantity of the slats can be set according to the specific length and the field situations of a tunnel.

The handle 13 is partly located in the wire holding box 11 and is connected with the bracket 12. One end of each of the safety fuses 7 with the steel wires passes through the bracket 12 and droops to the tunnel ground.
In the case of no fire, the roller shutter is hooked, not affecting the ventilation and is aesthetically pleasing. When a fire occurs, the slats 1 droop to the ground.
After the slats 1 droops to the ground, the previous slats overlays the next ones one by one in succession, thus playing a better sealing role and effectively blocking the spread of the smoke.
The operations of the triggering device can be classified into two types, namely manual triggering and automatic triggering, when a fire occurs.
8 1. Automatic triggering When a fire occurs, the fire ignites the safety fuses 7 with the steel wires.
The safety fuses are quickly exhausted. When the safety fuses 7 with the steel wires only have the steel wires left, the diameter is greatly reduced. At this time, the gap between the bracket 12 and the steel wires increase. By the gravity effect of the slats 1, the pulling force is far greater than the friction force between the bracket 12 and the steel wire, and then the steel wires are automatic extracted from the bracket 12. Without the pulling force, the slats 1 automatically drop off from the hooks 9 of the rear-end fixed guide rail 5 and droops down automatically, thereby closing the fire field.
2. Manual triggering When a fire has just occurred and has not reached and ignited the safety fuse, the handle 13 can be manually pulled down. When the handle 13 is pulled down, the bracket 12 releases, and the safety fuses 7 with the steel wires are automatically extracted from the bracket 12 by the effect of the pulling force, so that the slats 1 drop off, droop and close the tunnel.
The above embodiments are only preferred embodiments of the present invention and shall not be regarded as limit of the present invention. Any modifications, equivalent changes and improvement made within the concept and principle of the present invention shall fall within the protective scope of the present invention.
