Unmanned aerial vehicle and method for patrolling abnormal seepage area of earth and rockfill dam

Abstract

The invention discloses an unmanned aerial vehicle aerial survey UAV and method for an abnormal seepage area of an earth-rock dam, and the UAV comprises a power system and a rotor system which work independently, a non-contact charging landing gear, and a safety airbag. Ducted fans with small thermal infrared characteristics and high mechanical efficiency and safety are used in the power system and the rotor systems, lift force and thrust are independently provided for the unmanned aerial vehicle, an electromagnetic mutual inductance coil matched with a ground charging platform is arranged inthe non-contact charging landing gear, and the unmanned aerial vehicle is automatically and rapidly charged. The safety air bag is driven by a high-pressure helium cylinder to pop up and can be repeatedly used. According to the unmanned aerial vehicle, the unmanned aerial vehicle can be used for patrolling and detecting abnormal seepage regions of earth-rock dams and weir bodies, has the functionsof vertical take-off, hovering and top-speed flight, and can realize ultra-long endurance, heavy load and crash protection at the same time.

Description

technical field [0001] The invention relates to an unmanned aerial vehicle, in particular to an unmanned aerial vehicle used for emergency survey operations in abnormal seepage areas of earth-rock embankments and a method for using the unmanned aerial vehicle to conduct emergency surveys. 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 occurred frequently, earth-rock embankments have prominent leakage diseases, and barrier lake disasters have frequently occurred. In China, from June to July 2020, major dangers occurred in many dams across the country; in October 2018, the Jinsha River formed a barrier lake, and more than 10,000 people were transferred urgently; in August 2018, the Dongfangshan Reservoir in Hubei was Leakage occurred in a major danger; in July 2016, a local embankment of the Jushui River, a first-class tributary of the Y...

AI Technical Summary

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.
