It can also promptly remind personnel to control the drone 100 to come back to add water when the water level inside the water tank 1 is low, thereby improving the stability of subsequent water spraying fire extinguishing.

[0029] Working principle: When in use, the camera 101 monitors the situation of the forest and transmits the monitored images to the controller 11 for analysis. At the same time, when the smoke sensor 102 senses the smoke, it transmits the information to the controller 11. When the controller 11 analyzes the fire event, it controls the sound and light alarm 12 to send out sound and light alarms to remind people, so that people nearby can avoid it in time. At the same time, the controller 11 transmits the signal to the external monitoring end APP, so that the people on the monitoring end can know and deal with it in time.

[0030] At the same time, the controller 11 also controls the water pump 3 and the reciprocating electric telescopic rod 14 to start. When the water pump 3 is turned on, the water inside the water tank 1 is extracted. The extracted water enters the annular tube 5 through the drain pipe 4 and the telescopic hose 6 in turn. The water inside the annular tube 5 is sprayed out through multiple atomizing nozzles 17 for water spraying and fire extinguishing. At the same time, the output shaft of the reciprocating electric telescopic rod 14 drives the U-shaped moving rod 13 to move right and left in a cycle through the connecting block. The U-shaped moving rod 13 drives the two racks 10 to move right and left in a cycle. The racks 10 drive the corresponding moving blocks 15 to slide on the positioning rods 16. 10 drives the gear 9 meshing therewith to rotate in a circular counterclockwise manner, the gear 9 drives the corresponding disc 8 to rotate in a circular counterclockwise manner, the disc 8 drives the corresponding connecting rod 18 to swing right and left in a circular manner, the two connecting rods 18 drive the annular tube 5 to swing right and left in a circular manner, the annular tube 5 drives the multiple atomizing nozzles 17 to swing right and left in a circular manner, so that the multiple atomizing nozzles 17 swing right and left in a circular manner during the process of spraying water, thereby increasing the water spraying range and improving the water spraying fire extinguishing effect. By timely and automatically swinging the water spraying fire extinguishing in a large range when a fire is sensed, the fire extinguishing effect is improved and the safety hazard is reduced;

[0031] When the water pump 3 pumps water, the liquid level inside the water tank 1 gradually decreases. The liquid level sensor 2 monitors the liquid level inside the water tank 1 and transmits the monitored liquid level value to the controller 11. When it is detected that the liquid level is lower than the preset value, the controller 11 controls the sound and light alarm 12 to emit a sound and light alarm to remind personnel, so that the personnel can know the lack of water in the water tank 1 in time and control the drone 100 to come back to add water.
