Intelligent fireproof door preventing smoke from leaking with high safety factor

Abstract

The invention relates to an intelligent fireproof door preventing smoke from leaking with a high safety factor. The intelligent fireproof door comprises a door frame, a door plate, a fireproof lock, an anti-fogging mechanism, and multiple strengthening mechanisms; each strengthening mechanism comprises a first motors and two strengthening assemblies; each strengthening assembly comprises a first drive shaft, a sleeve, a jack and two clamping plates; the anti-fogging mechanism comprises a top plate, a humidifying assembly, a shrinking assembly, a lifting plate, and two sliding assemblies; the shrinking assembly comprises an anti-fogging cloth, a second motor, a buffer block and a second drive shaft; the humidifying assembly comprises a water storage tank, a water pipe and a sprinkler; according to the intelligent fireproof door preventing smoke from leaking with the high safety factor, the sleeve is inserted in the jack located the inner wall of the door frame through the strengtheningmechanisms, the reinforcement of the door plate is realized, the deformation of the door plate caused by impact and extrusion of the expanded air is avoided, the safety factor of the device is improved; and not only that, through the anti-fogging mechanisms blocking ae gap between the door plate and the door frame, the smoke is prevented from diffusing, it is ensured that people can escape safely,and the practicality of the device is improved.

Description

technical field [0001] The invention relates to the field of firefighting equipment, in particular to an intelligent fire door with high safety factor against smoke leakage. Background technique [0002] Fire doors refer to doors that can meet the requirements of fire resistance stability, integrity and heat insulation within a certain period of time. In addition to the function of ordinary doors, fire doors also have the function of preventing the spread of fire and smoke. It can prevent the spread of fire within a certain period of time and ensure the evacuation of people. [0003] However, after the existing fire doors are closed, there is still a gap between the door panel and the door frame, so that when a fire occurs, smoke can flow from the gap between the door frame and the door panel into the protection range of the fire door, reducing the visibility in the protection range Not only that, when the fire is serious, due to the thermal expansion of the air, it will ha...

[0003] However, after the existing fire doors are closed, there is still a gap between the door panel and the door frame, so that when a fire occurs, smoke can flow from the gap between the door frame and the door panel into the protection range of the fire door, reducing the visibility in the protection range Not only that, when the fire is serious, due to the thermal expansion of the air, it will have a strong impact and extrusion force on the door panel, which will easily cause the deformation of the door panel, causing the fire to pass through the fire door and affect the personnel inside the fire door. Personal safety, thereby reducing the safety factor of existing fire doors
