Rapid isolation automatic spraying roller shutter

Abstract

The invention belongs to the technical field of fire-fighting equipment, and particularly relates to a rapid isolation automatic spraying roller shutter. The roller shutter comprises a door curtain and a guide rail, the top of the guide rail is rotationally connected with a rotating shaft through a pair of supports, the periphery of the rotating shaft is fixedly connected with a reel through spokes, gear motors are fixedly connected to the positions, corresponding to the rotating shaft, of the supports, the top of the door curtain is fixedly connected with the reel, the door curtain comprisesa group of flexible curtains which are in sliding connection with each other, and the adjacent flexible curtains are in sliding connection. According to the rapid isolation automatic spraying roller shutter, when the door curtain encounters an obstacle in the descending process, the flexible curtains at the corresponding positions stop abutting against the obstacle and stopping moving downwards, the flexible curtains at other positions continue to move downwards and make contact with the ground, and the isolation sealing performance of the door curtain to an escape way is improved.

Description

technical field [0001] The invention belongs to the technical field of fire-fighting equipment, in particular to a rapid isolation automatic spraying roller shutter. Background technique [0002] The fire shutter door is a kind of fire prevention and heat insulation facility suitable for large openings of buildings. The product plays a certain role in the design and installation of technology. Fire shutter doors are widely used in the fire partition areas of industrial and civil buildings, which can effectively prevent the spread of fire and ensure the safety of life and property. They are indispensable fire prevention facilities in modern buildings. [0003] There are also some technical solutions about fire shutters in the prior art. For example, a Chinese patent with application number 2018105001085 discloses a fire shutter door, which includes a main body and a wall. There is an axis, a baffle is welded on the right side of the axis, a door curtain is connected to the b...

AI Technical Summary

Problems solved by technology

[0005] In order to make up for the deficiencies of the prior art and to solve the problem in the prior art when a fire breaks out, the flame and toxic smoke are isolated by putting down the fireproof shutter to increase the safety of personnel evacuation, but when there is an obstacle at the bottom of the shutter door, the shutter door cannot be completely dropped , resulting in a serious decline in the sealing of the rolling shutter door, which affects the safety of fire rescue. The rapid isolation and automatic spraying rolling shutter proposed by the present invention
