Description

Technical Field

[0001] The invention relates to the technical field of forest fire monitoring, and in particular to a forest fire monitoring drone. Background Art

[0002] Forest fire is the most dangerous enemy of forests and the most terrible disaster of forestry. It will bring the most harmful and devastating consequences to forests. Forest fire not only burns large tracts of forests and harms animals in the forests, but also reduces the forest's regeneration capacity, causes soil impoverishment, destroys the forest's role in conserving water sources, and even causes the ecological environment to lose balance. Although science in today's world is developing rapidly, humans have not yet made great progress in conquering forest fires; therefore, forest fire prevention and detection are more practical than extinguishing them.

[0003] The invention patent with patent application announcement number CN213139143U discloses a drone aerial photography device for real-time monitoring of forest fires, including a drone, wherein sleeves are fixedly connected to the left and right sides of the bottom of the drone, a baffle is matched with the inner wall gap of the sleeve, and a spring is fixedly connected to the left side of the baffle, and the present invention relates to the field of drone technology. The drone aerial photography device for real-time monitoring of forest fires has the effect of reducing dew when the drone lands through the cooperation between the sleeve, the inclined rod, the baffle, the through hole, the spring and the roller, consumes the falling kinetic energy of the drone, reduces the shaking time of the drone and protects the drone, and through the cooperation between the water tank, the water pump, the short pipe and the nozzle, the drone aerial photography device for real-time monitoring of forest fires can take water spraying measures in time when a small fire or fire precursor is found, so as to buy time for the staff to arrive at the scene.

[0004] However, the above device still has some shortcomings in actual use. The most obvious one is the lack of shielding protection for the propeller. When the drone flies in the forest, the propeller is easy to contact with branches, causing the drone to fly unbalanced or even crash. Therefore, in order to solve this problem, we proposed a forest fire monitoring drone. Summary of the invention
