When the temperature or pressure exceeds the set upper limit of the sealing strip, the graphite-based composite expanded material overflows and expands from the edge of the embedded fireproof sealing strip 5 to fill the wall gap at the installation position to prevent the spread of fire and smoke. When a fire electrical fault occurs, the magnetorheological damper 24 switch is opened by manually pushing and pulling the handle 7 to change the locking damping, ensuring that the fire door can be manually opened for rapid escape.
[0031] Working principle: The infrared intelligent sensor 4 collects the height, moving speed, width and other parameters of the inspection robot in real time, and sends the door opening mode and door opening angle signal in real time according to the preset program; The synchronous door opening module and the folding door opening module cooperate with the door damping adjustment module to open the fire door in real time according to the received door opening signal, ensuring that the inspection robot can pass smoothly; The self-closing door module and the reset spring 19 automatically close the integrated door 6 under different door opening modes, and cooperate with the door body damping adjustment module to ensure that the fire door is closed.
