Unmanned aerial vehicle

Abstract

The invention relates to the technical field of aircrafts and discloses an unmanned aerial vehicle which comprises a machine body in communication connection with a ground station; the machine body comprises a machine main body and two wings symmetrically arranged on the two sides of the machine main body; the machine main body is internally provided with a central control unit; the machine body is in communication connection with the ground station through the central control unit; the bottom of the machine main body is provided with a first camera used for photographing a flight environmentand a second camera used for photographing the ground condition; a radar cover is detachably connected to the bottom of the machine main body and is internally provided with a laser radar; the bottomof the radar cover is provided with a laser scanning hole, through which a laser beam emitted by the laser radar passes; the first camera, the second camera and the laser radar are all electrically connected with the central control unit; and the aspect ratio of each wing is larger than or equal to 12. By adopting unmanned aerial vehicle provided by the invention, the efficiency of laser radar inspection can be improved, the quality of data acquired by the radar is improved, and the probability of collision of the unmanned aerial vehicle and the laser radar is reduced, so that the safety of the machine body is improved, and the inspection cost is lowered.

Description

technical field [0001] The invention relates to the technical field of aircraft, in particular to an unmanned aerial vehicle. Background technique [0002] In order to grasp the operation status of the transmission and distribution lines and equipment, the staff need to inspect the transmission and distribution lines on a regular basis to find out the defects of the lines and equipment in time, so as to carry out targeted maintenance and treatment, and eliminate the existing safety hazards. [0003] The efficiency of inspection of transmission and distribution lines by manual inspection is low, and the quality of inspection is difficult to guarantee. Therefore, the quality of data collected by this traditional inspection method is not high. Moreover, the current cost of employment is constantly rising, and the requirements for the relevant work of the staff are also getting higher and higher. The cost of manual inspection is relatively high, but the efficiency of inspection ...

AI Technical Summary

Problems solved by technology

From the formula P=hn / fv, it can be known that under the same radar power and flight altitude, the flight speed is inversely proportional to the scanning frequency of the laser radar, so a faster flight speed will greatly reduce the detection quality of the radar, resulting in the existing The quality of data collected by drone inspections is poor, and drones need to fly multiple times to obtain accurate data, which reduces the efficiency of inspections
