Fireproof door capable of realizing automatic door body cooling

Abstract

The invention discloses a fireproof door capable of realizing automatic door body cooling. The fireproof door comprises a door frame, a door head and a door body, wherein the door head is transverselyerected on the door frame; the door body is hinged to one side of the door frame; a water storage cavity in transverse arrangement is arranged inside the door head; a plurality of water outlet holesare formed at the lower end surface of the door head; a plug body made of PE plastic materials is embedded in each water outlet hole; a first water inlet pipe and a first smoke sensing switch are arranged at one side of the door head; the first smoke sensing switch is used for controlling the break-and-make state of the first water inlet pipe after detecting the smoke information in an indoor position; after the indoor temperature rises to 120 DEG C or higher, the plug body is naturally molten and softened to expose the water outlet hole; water flow flowing out from the water outlet hole is poured onto the door body to cool the door body; water mist is formed, so that the smoke is prevented from passing through seams on the periphery of the door body; the inside of the door body is hollowand forms an accommodating cavity; a second water inlet pipe and a second smoke sensing switch are connected under the door body. By adopting the technical scheme, the door body can be automaticallycooled; the smoke entering is prevented; the survival possibility of people in fire hazards can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of fire doors, in particular to a fire door capable of automatically cooling a door body. Background technique [0002] After a fire broke out, people were killed mainly because of two reasons. One is that they were affected by the smoke and poisonous gas of the fire, and the other is that because they are generally high-rise buildings, it is difficult to escape to the outside after a fire and they are burned to death or killed by the smoke. . Among them, among the various components of fire smoke, carbon monoxide is the main poisonous gas. The human body will experience breathing disorders, loss of consciousness, convulsions, and even suffocation in a short period of time. And combustible materials can produce a lot of toxic smoke when they are pyrolyzed or burned, such as nitrogen oxides, formaldehyde, isocyanates, hydrogen fluoride, hydrogen chloride and other irritating gases. When the toxic gas reach...

AI Technical Summary

Problems solved by technology

[0003] At present, indoor doors are generally made of fire-resistant board materials, but in fact, due to the limitations of the material itself, the fire-resistant limit generally can only reach 160 degrees Celsius to 180 degrees Celsius, and bending damage will occur if it goes higher, and the fire scene, The indoor temperature can usually reach above 200 degrees Celsius, which means that after the fire, the fire-resistant doors are usually bent and deformed or have been burned.

At the same time, the door body is generally not sealed, and the smoke and poisonous gas can easily pass through the gaps, which further reduces the survival rate of people after the fire. It is easy to cause great damage to life and property. Even if people are lucky enough to escape outside and survive, the smoke inhaled on the road will also have a greater impact on people's health
