[0002] A drone is different from a traditional airplane. It means an unmanned aircraft. Its main function is to conduct reconnaissance and transmit information back. It is mainly divided into two types: military and civilian. In order to better protect the environment in which people live, it is generally necessary to use environmental monitoring drones to fly back and forth to monitor the environment in the area.

[0003] At present, during the flight of environmental monitoring drones, such as when monitoring urban environments or outdoor environments, low-altitude flight is often required. However, the propellers of the rotors are more likely to hit obstacles during low-altitude flight. For example, a drone low-altitude flight protection device disclosed in the authorization announcement number CN218431768U surrounds the propeller of the drone body through a protective fence, thereby avoiding collision between the propeller and obstacles during low-altitude flight. For example, a portable drone protection mechanism disclosed in the authorization announcement number CN219447318U, although it is convenient for the propeller of the drone to be protected by providing a rotating block, a connecting plate, an adjustment groove, a slider, a stabilizing plate and a protective plate, and the slider and the rotating connecting plate are moved to quickly retract the protective plate and the protective rod, thereby reducing the occupied space and facilitating the carrying and storage of the protective mechanism, it does not solve the problem that the protective plate and the protective rod are mainly fixed by bolts, and tools are needed to retract them in actual use, which is inconvenient. For this reason, we propose a protective environmental monitoring drone. Utility Model Content

At this time, even if the driving ring 12 is rotated, the adjusting threaded rod 8 will not be rotated, and the movable sleeve 6 will not move abnormally due to accidental contact with the driving ring 12. It has good safety performance in use. Later, when the movable sleeve 6 needs to be extended, the driving ring 12 can be reversed.

[0022] Environmental monitoring staff can assemble the protective mechanism according to the needs of the UAV body 1 when performing environmental monitoring during low-altitude flight, and utilize the cooperation between the drive ring 12, the adjusting threaded rod 8, the fixed sleeve 5 and the movable sleeve 6 to facilitate the folding of the movable sleeve 6, thereby facilitating the folding of the protective mechanism. Utilizing the cooperation between the drive ring 12, the connecting column 10 and the drive block 9, the movable sleeve 6 can be moved without using tools.

When it needs to be folded, the half ring 13 is reversed so that the connecting block moves back along the groove until the half ring 13 is perpendicular to the driving ring 12.
