By starting the thermal camera 2011, the thermal camera 2011 will capture the thermal image in front and analyze whether there is a fire in the local area. When a fire is detected, the device will move to the fire scene and then start the stepper motor 2001. The stepper motor 2001 rotates to drive the first turntable 2004 and the connecting rod 2005 to rotate. The connecting rod 2005 rotates through the sliding pin to drive the groove wheel 2006 to rotate. The rotation of the groove wheel 2006 drives the second turntable 2007 to rotate. The rotation of the second turntable 2007 drives the ordinary camera 2009, the nozzle 2010 and the thermal camera 2011 to rotate.

The two second electric telescopic rods 3104 are simultaneously activated, causing them to retract. This retraction drives the two door panels 3101 to move toward opposite directions. Guided by the guide slots 3103, the door panels 3101 are retracted into the interior of the body 1001. The second stepper motor 3209 is then activated. The rotation of the second stepper motor 3209 drives the first bevel gear 3210, which in turn drives the second bevel gear 3211. The rotation of the second bevel gear 3211 drives the fourth bevel gear 3214, which in turn drives the second rotating shaft 3215. The rotation of the second rotating shaft 3215 drives the universal joint 3216, which in turn drives the screw 3206. The rotation of the screw 3206 drives the threaded sleeve 3205 to move. The movement of the threaded sleeve 3205 drives the third fixing plate 3201 to move. This causes the third fixing plate 3201 to move the sound and light alarm 3202, the laser radar 3203, and the air collector 3204, extending them outside the fuselage 1001. The laser radar 3203 then scans and constructs a map of the fire scene, planning a firefighting route for the device. The sound and light alarm 3202 then sounds an alarm, prompting people near the fire scene to leave as quickly as possible. Finally, the air collector 3204 collects air at the scene to facilitate later analysis of the cause of the fire.
