Door structure for fire fighting access

Abstract

The invention discloses a door structure for a fire fighting access. The door structure comprises a door panel and a door frame, wherein the circumferential outer side wall of the door panel sinks inwards so as to form an annular containing groove, and a water swelling sealing rubber strip is embedded in the annular containing groove; the door panel is internally provided with a plurality of annular pipelines, and all the annular pipelines are communicates with each other; a plurality of water outlets are circumferentially formed in the door panel near the annular pipeline arranged at the outermost side, and are communicated with the bottom of the annular containing groove; the lower end of the door panel is provided with a water inlet communicated with the annular pipelines; a wall body is provided with a water supply mechanism, and the water supply mechanism is provided with a water outlet pipe. When the door is closed, the water outlet pipe is communicated with the water inlet; thewall body is provided with a smoke sensor and a controller. The smoke sensor and the water supply mechanism are separately and electrically connected with the controller. The invention provides the door structure for the fire fighting access, and a cooling passage is arranged inside the door structure; when a fire hazard occurs, a door body is cooled in time, so that the fire blocking time is prolonged.

Description

Technical field [0001] The invention relates to the technical field of fire-fighting equipment, in particular to a door structure for fire-fighting passages. Background technique [0002] Fire door refers to a door that can meet the requirements of fire stability, integrity and heat insulation within a certain period of time. It is a fire partition with a certain degree of fire resistance, such as fire compartments, evacuation stairwells, and vertical shafts. In addition to the function of ordinary doors, fire doors also have the function of preventing the spread of fire and smoke, which can prevent the spread of fire within a certain period of time and ensure the evacuation of personnel. [0003] Conventional fire doors, as long as the fire is blocked by steel or steel-wood doors with flame retardant attached, can prevent the fire from expanding within a certain period of time, but in a closed room with important equipment, it is neither possible to transfer the equipment nor eas...

AI Technical Summary

Problems solved by technology

[0003] As long as the conventional fire doors block the fire through steel or steel-wood doors with flame retardants, they can prevent the fire from expanding within a certain period of time, but in a closed room where important equipment is installed, it is neither possible to transfer the equipment nor easy to extinguish the fire. , even if the fire door can temporarily stop the fire, it is still easy to cause equipment burns and property damage

[0004] Moreover, the conventional fire doors themselves do not have the functions of cooling and heat dissipation. If the fire doors cannot be cooled and insulated in time, the time for blocking the flame will be greatly reduced. If the firefighters cannot arrive in time, the fire doors will be burned. greatly increased risk
