The invention relates to an automatic fire disaster door-closing device. The automatic fire disaster door-closing device comprises a main hydraulic machine, an arm lever, a rotary shaft, a connecting plate and a clamping device and further comprises a smoke monitoring device, a naked fire monitoring device and a driving device, wherein one end of the arm lever is connected with the main hydraulic machine; the rotary shaft is fixedly connected with the other end of the arm lever; one end of the connecting plate is connected with a door frame; the other end of the connecting plate is rotationally connected with the rotary shaft; the clamping device is mounted on the connecting plate; the naked fire monitoring device is installed on the connecting plate; the driving device is mounted on the connecting plate and respectively connected with the smoke monitoring device and the naked fire monitoring device; the driving device is connected with the clamping device. When presence of smoke or naked fire is monitored, the driving device drives the clamping device to be separated from the rotary shaft so that a door can be closed. By means of the automatic fire disaster door-closing device, technology upgrading cost of existing products is reduced, the device can respond in time according to the smoke and fire during operation, and the door can be controlled to be closed. Power consumption of the device is required only for monitoring of temperature changes, so that cost is reduced. The automatic fire disaster door-closing device is simple in structure and high in integration level, and mounting difficulty requirements are low.
