Intelligent automatic fire door

Abstract

The invention discloses an intelligent automatic fire door, and relates to the technical field of fire doors. The intelligent automatic fire door comprises an assembly door frame, wherein a fire doorsheet is movably hinged to one end of the assembly door frame, a bearing seat is fixedly arranged on the upper end of the front side of the assembly door frame, a driving winding roller is rotatably connected to one end of the bearing seat, a flame retardant mat wraps the surface of the driving winding roller, a balancing weight is fixedly arranged on the bottom end of the flame retardant mat, anda smoke sensor is fixedly arranged on the upper end of the back side of the assembly door frame. The surrounding smoke concentration and temperature are monitored in real time, so that when the smokeconcentration and temperature are abnormal in a fire condition, an audio and video alarm is given in time by an audible and visual alarm so as to remind emergency evacuation of personnel, when all ofthe personnel pass through the fire door, the unfolded flame retardant mat falls so as to achieve good protecting and insulating effects, so that the personnel are prevented from being scalded by high-temperature shock wave during evacuation, and the flame retardant insulation performance of the fire door is improved by a flame retardant plate layer, an insulting plate layer, a flame retardant cavity and flame retardant materials.

Description

technical field [0001] The invention relates to the technical field of fire doors, in particular to an intelligent automatic fire door. Background technique [0002] With the country's large-scale infrastructure construction, the demand for fire doors used in buildings is increasing, and the performance requirements are getting higher and higher, such as the subways being built in some large and medium-sized cities, the reconstruction and expansion of airports and stadiums, etc., fire doors It is an important part of fire-fighting equipment and an important part of social fire prevention. [0003] However, the degree of intelligent automation of traditional fire doors is low, and it is impossible to remind personnel to carry out emergency evacuation in time. Due to the poor protective and heat insulation performance of the door panels, people are easily scalded by high temperature shock waves during evacuation. The flame retardant and heat insulation performance of fire door...
