Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicles, in particular to an unmanned aerial vehicle for inspection. Background Technique

[0002] Due to its small size, low energy consumption and easy operation, the unmanned aerial vehicle has become a much-sought-after small aircraft at present. With the development and popularization of unmanned aerial vehicle technology, unmanned aerial vehicles have been widely used in aerial photography, agriculture, forestry, mapping and other fields.

[0003] The authorized announcement number CN212473939U discloses an unmanned aerial vehicle for inspection. The patented technology is provided with a spotlight head at the bottom of the fuselage, which enables the unmanned aerial vehicle to conduct inspections at night or in poor visibility conditions. The addition of a stepping motor can effectively control the lighting angle, and at the same time, the installation of a loudspeaker can issue a warning through the console, effectively improving the inspection effect. The shock absorber can effectively reduce the impact force generated during the takeoff and landing of the unmanned aerial vehicle. At the same time, the application of the telescopic rod enables the unmanned aerial vehicle to take off and land in different regions, protecting the unmanned aerial vehicle and facilitating inspections. However, the existing lightning protection detection work is mostly completed by manually carrying test lines, that is, the detection personnel carry test lines on the top of the building to conduct lightning protection detection on the direct lightning protection devices of the building, such as the roof lightning protection belt, lightning rod, etc. For dangerous positions such as pitched roofs and high towers, it is very difficult for the detection personnel to reach the top. Therefore, the lightning protection detection for these high-risk positions has always been blank. The detection process is highly dangerous. It is dangerous for the detection personnel to stand on the top of a high building, and it is easy to occur an accidental event where when the detection personnel throw the test line down from the top of the high building, the test line falls on the high-voltage line and causes the detection personnel to be electrocuted to death. Therefore, an unmanned aerial vehicle for inspection is needed to improve the above problems. Content of the Utility Model
