Folding-unfolding type mechanical fire canopy with automatic opening function and using method thereof

Abstract

The invention discloses a folding-unfolding type mechanical fire canopy with an automatic opening function. The folding-unfolding type mechanical fire canopy comprises a fire prevention shed capable of being folded and unfolded, a controller, a locking switch, a locking mechanism, a first connecting rope, a second connecting rope and a pulley set, wherein the controller is used for controlling folding and unfolding of the fire prevention shed and opening the fire prevention shed automatically when the temperature is larger than a certain value; the locking switch is arranged on the controller, the locking mechanism is arranged on the fire prevention shed and used for keeping opening of the fire prevention shed; the fire prevention shed and the controller are connected through the first connecting rope; the locking mechanism and the locking switch are connected through the second connecting rope; and the pulley set is used for allowing passing of the first connecting rope and the second connecting rope. The fire prevention shed is of a fan-shaped structure so as to be capable of well controlling flames and smoke in the fire prevention shed, and upward going of the flames is reduced; the fire prevention shed can be folded in a normal situation and can be opened rapidly by utilizing the electromagnet principle; and by arranging a temperature-sensitive piece, when a fire occurs indoors and a person has little time to open the fire prevention shed, the fire prevention shed is automatically opened after the temperature reaches the certain value, and thus the folding-unfolding type mechanical fire canopy has good practical value.

Description

technical field [0001] The invention relates to the field of fireproof overhanging eaves, in particular to a retractable mechanical fireproof overhanging eaves with an automatic opening function and a method for using the same. Background technique [0002] At present, with the continuous improvement of my country's economic level, high-rise buildings continue to appear, and the fire rescue of high-rise buildings has become a difficult problem. The fire in high-rise buildings spreads quickly. Under the action of wind, the fire rises up along the windows of the outer wall, and even jumps to the upper floors, making it difficult to control the fire. The fire resistance and fire extinguishing of domestic high-rise buildings mainly use spraying or fireproof overhanging eaves with fixed structures. Although the fire-proof overhangs with fixed structures can hinder the spread of flames, when a fire occurs, the unburned smoke will flow out of the windows and continue to burn outsi...
