A steel automatic fire shutter

Abstract

The invention discloses a steel automatic fireproof roller shutter which comprises a bottom plate, a shutter face, an automatic winding device and a guide rail assembly. The upper end of the shutter face is wound in the winding device. The bottom of the shutter face is connected with the bottom plate. The automatic winding device comprises a winding shaft, a shutter winding machine and an automatic control device. The winding shaft is connected with the shutter winding machine. The automatic control device comprises a control box and a temperature-sensing probe. The temperature-sensing probe is used for detecting environment temperature and sending out a temperature detection signal. The control box is used for receiving the temperature detection signal and drives the shutter winding machine to rotate. The guide rail assembly comprises a left guide rail and a right guide rail. The left end and the right end of the shutter face are connected with the left guide rail and the right guide rail respectively in a sliding mode. The steel automatic fireproof roller shutter has the advantages of being good in fireproof performance, and capable of preventing a fire and isolating heat in time and having the function of automatically extinguishing a fire.

Description

technical field [0001] The invention relates to a rolling shutter, in particular to a steel automatic fireproof rolling shutter. Background technique [0002] With the country's large-scale infrastructure construction (such as subways, airport expansion and stadiums), the demand for roller blinds 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 closed in time, which cannot protect indoor safety. . In addition, the traditional roller shutter does not...

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 closed in time, which cannot protect indoor safety.

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.
