Problems solved by technology

Once the UAV crashes during flight, on the one hand, it will cause damage to the UAV itself and the survey equipment carried on it, and on the other hand, it may injure people and destroy objects, so special consideration should be given to the protection of UAV crashes
[0007] In addition, the existing civilian UAVs generally have low battery life, strong convection resistance and waterproof functions, and it is difficult to achieve long-distance and long-duration flight and all-weather earth-rock embankment inspection under severe weather conditions.

Embodiment Construction

[0037] The technical solutions of the present invention will be further described below with reference to the accompanying drawings.

[0038] like figure 1 As shown in the figure, the unmanned aerial vehicle used for emergency inspection of abnormal leakage areas of earth-rock dams in the present invention is generally configured as a delta airfoil. The device 5, the crash protection device 6, the flight control and navigation system 8 and the data acquisition system 7 are composed. The power system, rotor system, tail, non-contact charging landing gear, crash protection device, flight control and navigation system and data acquisition system are all integrated on the fuselage, wherein the power system provides the thrust of the drone to fly forward, and the rotor The system provides the necessary lift for the UAV to fly. The power system and the rotor system work independently during flight and are not related to each other.

[0039] like figure 2 As shown in the figure, ...

Abstract

The invention discloses an unmanned aerial vehicle and a method for aerial inspection of an unmanned aerial vehicle in an abnormal seepage area of ​​an earth-rock dam. The ducted fan with small thermal infrared characteristics and high mechanical efficiency and safety is used for the UAV and the rotor system to independently provide lift and thrust for the drone. The mutual inductance coil automatically charges the drone quickly, and the airbag is driven by the high-pressure helium cylinder to pop up, which can be reused. The invention enables the UAV to be used for the inspection of the abnormal seepage area of ​​earth-rock dams and damming bodies, so that the UAV has the functions of vertical take-off, hovering, and high-speed flight, and at the same time, it can realize ultra-long endurance, large load and crash. machine protection.

Description

technical field [0001] The invention relates to a method for unmanned aerial vehicle inspection operation, in particular to a method for unmanned aerial vehicle to carry out inspection operation in abnormal seepage area of ​​earth-rock dams Background technique [0002] The vast majority of reservoir dams and embankments are made of earth and rock. In recent years, with the impact of global climate change, extreme weather has frequently occurred, leakage of earth and rock dams has become prominent, and dammed lake disasters have occurred frequently. In China, from June to July 2020, major dangers occurred in many dams across the country; in October 2018, the Jinsha River formed a dammed lake, and more than 10,000 people were urgently transferred; There was a major danger of leakage; in July 2016, a partial embankment of the Qishui River, a first-class tributary of the Yangtze River, burst due to leakage and piping. Such dangers will cause serious threats to life and propert...
