The camera unit is arranged on a fixed frame, and the fixed frame is connected to a lifting push rod for driving it to move up and down. However, this device "can fold the legs under the arms during flight, reducing the flight wind resistance and improving the endurance", and the legs are still completely exposed after being folded. During the flight, the legs will generate a certain amount of wind resistance, affecting the endurance of the UAV. Summary of the invention

[0003] In view of the above-mentioned deficiencies in the prior art, the utility model provides a UAV device for forest fire monitoring operations. When the UAV device is used for forest fire monitoring operations, a bidirectional driving screw drives the supporting foot driving blocks to approach each other.
