A double curtain automatic fire shutter

Abstract

The invention discloses an automatic fire resisting shutter with two pieces of shutter cloth. The automatic fire resisting shutter comprises the outer shutter cloth, the inner shutter cloth, a door roller and an automatic control device. The outer shutter cloth is arranged on the outer side of the inner shutter cloth. The door roller controls the outer shutter cloth and the inner shutter cloth to ascend and descend. The automatic control device comprises a control box, a temperature detecting probe and a smoke detecting probe. The temperature detecting probe is used for detecting the environment temperature and sending out a temperature detecting signal. The smoke detecting probe is used for detecting the concentration of environment smoke and sending out a smoke detecting signal. The input of the control box is connected with the temperature detecting probe and the smoke detecting probe and used for receiving the temperature detecting signal and the smoke detecting signal and driving the door roller to rotate. The automatic fire resisting shutter with the two pieces of shutter cloth has the advantages of being good in fire resisting performance and capable of automatically resisting fire and insulating heat in time and achieving the automatic fire extinguishing function.

Description

technical field [0001] The invention relates to a rolling shutter, in particular to a double-curtain automatic fireproof rolling shutter. Background technique [0002] With the country's large-scale infrastructure construction (such as subways, expanded airports and stadiums), the demand for rolling doors used in buildings is increasing, and the performance requirements are getting higher and higher. In these important places, the level of fire protection alert is getting higher and higher. [0003] At present, the opening or closing of the fire shutters used in densely populated shopping malls, underground parking lots, and clubs needs to be done manually. When a fire occurs outdoors, the indoor staff often cannot find the fire in time. When the fire in the external environment is large, the staff is not easy to get close to the roller blinds, and the roller blinds cannot be opened in time, which cannot protect indoor safety. . In addition, traditional fire shutters are ...

AI Technical Summary

Problems solved by technology

When a fire occurs outdoors, the indoor staff often cannot find the fire in time. When the fire in the external environment is large, the staff is not easy to get close to the roller blinds, and the roller blinds cannot be opened in time, which cannot protect indoor safety.

In addition, traditional fire shutters are mostly single-layer structures, and their fire resistance needs to be improved.

In addition, the traditional roller shutter does not have its own fire extinguishing device, so it cannot automatically extinguish the fire.

Moreover, the bottom plate of the traditional roller blind is in rigid contact with the ground, and there are gaps, so the fire prevention and smoke prevention effects need to be improved.
