Automatic receiving and releasing device of unmanned aerial vehicle for high-voltage transmission line inspection

Abstract

The invention discloses an automatic receiving and releasing device of an unmanned aerial vehicle for high-voltage transmission line inspection, and belongs to the technical field of unmanned aerial vehicle application and power detection. The automatic receiving and releasing device of the unmanned aerial vehicle is composed of four parts, namely, a turnover-plate-type closed box which can be opened and closed automatically, a central parking apron which can be lifted and lowered automatically, a two-way push-rod-type clamping fixation mechanism installed on the central parking apron and theturnover-plate-type closed box, and a ground control system. The autonomous landing of the unmanned aerial vehicle is completed by adopting a GPS and vision complementary positioning method and a double-graphics fast recognition and positioning algorithm, so that it is ensured that the unmanned aerial vehicle lands accurately on a landing platform composed of the parking apron which can be liftedand lowered automatically and a turnover-plate-type cabin door. The automatic receiving and releasing device of the unmanned aerial vehicle for high-voltage transmission line inspection provides a practical and effective solution for unmanned and intelligent inspection operation of transmission lines, particularly for autonomous launching and automatic positioning and landing and automatic charging of the unmanned aerial vehicle in the transmission line inspection, and can be applied to ground carrying robots, automobiles or ground base stations.

Description

technical field [0001] The invention relates to an unmanned aerial vehicle automatic retractable device for patrol inspection of high-voltage transmission lines, and belongs to the technical field of unmanned aerial vehicle application and electric power detection. Background technique [0002] With the continuous improvement of my country's comprehensive national strength and the vigorous development of economy and technology, my country's demand for conventional energy (such as electric energy) is still very strong. However, according to my country's current power supply and demand forms, cities and regions with large power demand are often not suitable for building power plants nearby. This kind of long-distance electric energy transmission has buried hidden dangers for the occurrence of accidents. Moreover, because the environment of the transmission line is an open-air place in the wild, it is susceptible to damage such as broken strands, wear, and corrosion due to vari...

AI Technical Summary

Problems solved by technology

Unloading the battery not only requires a complicated mechanical structure, but also is difficult to control and takes a lot of time; although the wireless charging method is simple to control, the charging efficiency is low and the charging time is long, which will waste electric energy. Machine automatic charging technology all can not satisfy the charging requirement of unmanned aerial vehicle described in the present invention

In addition, drones must be protected in case of dust, thunderstorms and other bad weather during field operations

[0013] (3) The traditional positioning and landing method has low precision and large deviation;

[0016] For existing inventions that cannot solve the problem that wind force, wind speed and other disturbances have an impact on UAV landing during inspection of field transmission lines: existing related inventions and technologies are only applicable to good weather conditions, and the UAV position and posture deviation is small Under the autonomous recovery of UAVs, for the field operation environment such as transmission line inspection, there are not only many external interference factors, but also there will be relatively large deviations during the landing process of UAVs.

[0017] How to complete the automatic and fast charging of the UAV and the fixed protection of the UAV: ​​Since the transmission line inspection is a field operation, the UAV needs to fly for a long time and long distance, but it is limited by the UAV's own battery life. Restrictions, it needs to be carried by a ground-carrying robot or car and can be automatically and quickly charged to ensure the continuous operation of the drone

Unloading the battery not only requires a complicated mechanical structure, but also is difficult to control and takes a lot of time; although the wireless charging method is simple to control, the charging efficiency is low and the charging time is long, which will waste electric energy
