Description

Technical Field

[0001] The utility model relates to the technical field of inspection drones, in particular to an urban inspection drone. Background Art

[0002] As an innovative inspection tool, urban inspection drones integrate multiple advanced technologies to improve the efficiency and accuracy of urban management. They rely primarily on the integrated application of drone remote sensing, computer vision, and wireless communications. These technologies together form the core of the drone inspection system, enabling comprehensive and efficient inspections of urban areas.

[0003] The prior art discloses a city road parking inspection drone with announcement number CN215155621U, which includes a drone shell and a landing gear. The two sides of the bottom of the drone shell are fixedly connected to the landing gear, and the bottom of the landing gear is sleeved with a kit. The four sides of the drone shell are fixedly connected to support blocks, and the top of the support blocks is fixedly connected to a driving mechanism. A first protective mechanism is provided at the end of the support block away from the drone shell, and a second protective mechanism is fixedly installed at both ends of the drone shell. Through the arrangement of the first protective mechanism, the second protective mechanism and the kit, the above device can effectively protect the drone shell and propeller during drone inspection, avoiding damage to the drone in the event of a collision. At the same time, during landing, the kit can effectively reduce the vibration caused to the components inside the drone when hitting the ground, thereby extending the service life of the drone.

[0004] The above-mentioned urban inspection drone is equipped with a first protective mechanism, a second protective mechanism and a kit. When the drone is inspecting, the first protective mechanism and the second protective mechanism can effectively protect the drone casing and propeller. However, the above-mentioned device only has a buffer component at the bottom, and no retractable probe is installed at the bottom of the drone. When the drone is flying at a low altitude, it can detect some specific situations through contact with the ground by the probe, and cannot judge the road conditions in time, resulting in unstable landing. The effect during use is not good, and this needs to be improved. Utility Model Content
