Abstract

The invention discloses an unmanned-plane-based composite insulator hydrophobicity detector, which comprises an unmanned plane main body, a suspension frame arranged at the bottom part of the unmanned plane main body, and a spraying insulation rod suspended at the top part of the inside of the suspending frame; a first end of the spraying insulation rod is provided with a spraying head, and a second end of the spraying insulation rod is provided with a balance module; the bottom part of the suspending frame is provided with a balance assistant module, the balance module and the balance assistant module are in electric signal connection with a fly control system on the unmanned plane main body; the balance assistant module comprises a servo motor arranged on the suspending frame and connected with the fly control system through the electric signal; the output shaft of the servo motor extends out of the bottom part of the suspending frame, and the lower end part of the output shaft of the servo motor is provided with a balance rod; the end part of the balance rod is provided with a balancing weight. By using the fly control system of the unmanned plane itself, the flight gesture of the unmanned plane is sensed, thus the horizontal state of the spraying insulation rod is controlled through the common effect of the balance module and the balance assistant module, so as to achieve the purpose of eliminating the inclination inertia.

Description

technical field [0001] The invention relates to a hydrophobicity detection device, in particular to a drone-based composite insulator hydrophobicity detection device. Background technique [0002] Composite insulators in transmission lines are often polluted by dirt such as dust. When the climate is relatively humid, a large amount of dirt is attached to the surface of composite insulators, resulting in a decrease in flashover voltage, and even flashovers will occur at rated operating voltages, causing the power grid to safe operation is greatly affected. Therefore, it is necessary to check the contamination on the surface of composite insulators of transmission lines and remove the contamination. The study found that there is a certain correlation between the dirt on the surface of the composite insulator and its hydrophobicity, so the degree of dirt attached to the surface of the composite insulator can be judged according to the strength of the hydrophobicity of the comp...

Problems solved by technology

However, this invention uses a multi-rotor UAV as a platform, and when it is equipped with testing equipment to detect the hydrophobicity of composite insulators, the flight of the multi-rotor UAV relies on the tilt of the aircraft to obtain the forward component force, and it also depends on the tilt when the flight stops. When the UAV is tilted, the insulating spray boom is tilted, and the insulating spray boom for hydrophobicity detection is longer (3 meters), which leads to the inconsistency between the inertial frequency caused by the tilting of the insulating spray boom and the attitude correction frequency of the UAV flight controller. , resulting in constant pitching and swaying, unable to hover stably
