Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicle structures, in particular to a monitoring probe structure for an unmanned aerial vehicle used for inspecting the appearance of large steel structures. Background Technique

[0002] Using an unmanned aerial vehicle to inspect the surface of a large steel structure is an efficient, flexible and low-cost inspection method. Especially when faced with complex, high-altitude or inaccessible structures, the unmanned aerial vehicle inspection shows significant advantages. The unmanned aerial vehicle can quickly cover a large area, reduce the inspection time, and improve the inspection efficiency. The unmanned aerial vehicle can easily reach areas such as high altitudes and complex structures that are difficult or impossible for humans to reach, and conduct comprehensive and multi-angle inspections. The unmanned aerial vehicle is equipped with inspection equipment such as a high-resolution camera or an infrared thermal imager, which can accurately detect cracks on the surface of the large steel structure. Through image processing technology, parameters such as the length and width of the cracks can be automatically identified and quantified. By using the structural photos or videos taken by the unmanned aerial vehicle and combining image processing technology, the deformation of the steel structure can be analyzed. This is of great significance for evaluating the stability and safety of the structure.

[0003] When the unmanned aerial vehicle inspects a large steel structure, it is necessary to bring the monitoring probe close to the surface of the steel structure for inspection. At this time, if there is a slight carelessness, it is very easy to hit the surface of the steel structure, resulting in the fall of the unmanned aerial vehicle, and it is easy to damage the monitoring probe and make it unable to continue to be used, increasing the maintenance cost of the unmanned aerial vehicle; therefore, we propose a monitoring probe structure for an unmanned aerial vehicle used for inspecting the appearance of large steel structures to solve the problems raised above.
