A special expressway inspection UAV in foggy weather

Abstract

The present invention relates to the technical field of unmanned aerial vehicle, specifically a special expressway inspection unmanned aerial vehicle for foggy weather, including a remote controller, a body, a power device, a monitoring device and a buffer device; the power device includes an arm and a rotor , the arm is evenly arranged on the side of the body, and the rotor is installed at the end of the arm; the present invention is provided with a buffer device at the bottom of the drone, so that the impact of the drone is converted into The kinetic energy of the hydraulic oil in the No. 1 chamber and the elastic potential energy of the spring make the UAV recover quickly and avoid damage to the UAV due to excessive impact; The generated heat is guided to the rotor to speed up the heat dissipation of the motor and prevent the motor from malfunctioning due to poor heat dissipation.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to a highway inspection unmanned aerial vehicle dedicated to foggy weather. Background technique [0002] DJI drones have developed rapidly in recent years. Due to the advantages of relatively low cost, good maneuverability, and convenient use of drones, drones have been used in aerial photography, geological surveys, high-voltage transmission line inspections, and oil field pipelines. Inspection, highway management, forest fire prevention inspection, poison gas survey, anti-drug and emergency rescue, ambulance and other civilian fields have extremely broad application prospects. In foggy weather, the visibility is low, and accidents are prone to occur on the expressway; therefore, special expressway inspection drones are often used to inspect the expressway, discover accidents in time, and feed back the information to the expressway in time Inspectors deal with ac...

Problems solved by technology

[0003] However, when the existing highway inspection drone lands, the impact force it receives is relatively large, which can easily cause damage to the internal structure of the drone and cause the malfunction of the drone; in addition, when a car accident occurs on the highway In the event of a fire, it is difficult for rescuers to reach the scene quickly, so they often send drones to the scene to check; when the drone hovers at the scene, the smoke and ash generated by the fire easily fall on the surface of the rotor; In foggy weather, water droplets are easy to form. Smoke and ash are combined with water droplets and adhere closely to the surface of the rotor. On the one hand, it will increase the rotational resistance of the rotor. Balance; and the drone hovering at the fire scene for a long time will cause the motor of the rotor to generate a lot of heat, and the temperature of the fire scene is high, it is not easy for the motor to dissipate heat, so the motor is prone to failure due to the difficulty of heat dissipation, which will cause the drone Difficulty continuing to work
