Induction type double-layer fireproof roller shutter

Abstract

The invention discloses an induction type double-layer fireproof roller shutter. The induction type double-layer fireproof roller shutter comprises a guide rail, shutter surfaces, a shutter rolling machine, a roller shutter controller, scrolls, a box body and a plurality of steel wire ropes. The shutter surfaces are hung down and mounted in the fixed guide rail. The steel wire ropes are vertically arranged and connected to the side faces of the shutter surfaces or are mounted in the shutter surfaces. The upper ends of the steel wire ropes are connected with the scrolls and rotate around the central axes of the scrolls to open and close the roller shutter up and down. The roller shutter controller is arranged outside the box body. The two parallel shutter surface layers are arranged in a spaced mode, the scrolls on the shutter surface layers are arranged in parallel, and the shutter rolling machine is arranged on the same sides of the two scrolls and drives the two scrolls to rotate in the same direction. The further improvements are that the shutter surfaces are formed by compositing fireproof glass fiber decoration cloth, fireproof cloth, fireproof shutter swung fireproof blanket and fireproof aluminum foil cloth in sequence, and a spot type photoelectric smoke sensing fire detector, a spot type temperature sensing fire detector and a temperature control release device are further arranged. The induction type double-layer fireproof roller shutter can be automatically closed during fires and is low in weight and good in fireproof effect.

Description

technical field [0001] The invention relates to the technical field of rolling shutters, in particular to a fireproof rolling shutter. Background technique [0002] Fire shutters are widely used in factories and mines, commercial facades, garages, shopping malls, hospitals and other public places or residences. Although steel roller shutters have better fire performance, they are relatively heavy. The fire shutters with fire curtains are lighter in weight, but with a single-layer curtain, the fire performance is poor. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the invention proposes an induction-type double-layer fireproof roller shutter that can significantly improve the fireproof performance. [0004] The present invention achieves technical goals through the following technical solutions. [0005] Induction-type double-layer fireproof shutter, including guide rail, curtain surface, rolling door machine, rolling shutter controller, ...
