Unmanned aerial vehicle

Abstract

The invention relates to an unmanned aerial vehicle, comprising an unmanned aerial vehicle aircraft, a cradle head and a shooting device, wherein the shooting device is installed at the lower part of the cradle head, the cradle head comprises an upper cradle head plate, a cradle head damping ball and a lower cradle head plate, the cradle head damping ball is connected with the upper cradle head plate and the lower cradle head plate respectively, and the lower cradle head plate is connected with a rotary motor. The used unmanned aerial vehicle can better meet requirements of power line inspection and is compatible with multi-functional devices to meet requirements of long-line power line inspection, self-stabilizing multi-angle zooming shot and self protection.

Description

technical field [0001] The invention relates to the field of unmanned aerial vehicles, in particular to a wireless remote control, control and mechanical design of an electric line patrol unmanned aerial vehicle. Background technique [0002] Unmanned aircraft, referred to as "UAV", is an unmanned aircraft controlled by radio remote control equipment and its own program control device. UAV has the characteristics of small size, light weight, low cost, flexible operation, and high safety. It is widely used in aerial photography, detection, search and rescue, resource exploration and other fields. It is technically feasible to use drones to inspect power lines, and it is of practical significance to promote the work of drones to patrol power lines. UAV power line inspection comprehensively checks the various equipment conditions of lines and towers at a relatively fast speed. At the same time, the precision instruments carried can detect deep-seated line faults and hidden fau...

AI Technical Summary

Problems solved by technology

[0003] 1) At present, most of the four-axis and six-axis aircraft are driven by electricity, and the materials used are mostly plastic fiberglass boards, etc., resulting in the drone body being too large and heavy;

[0004] 2) The structure of the gimbal and fuselage carried by most UAVs is complex, which cannot fully achieve 360° shooting without dead angles, and even part of the angle is blocked by the fixed landing gear, and there is no camera protection device for emergency landing;

[0005] 3) The drone itself has the problem of large jitter and strong vibration during flight. In order to ensure the quality of aerial photography and protect the aerial photography equipment, it is necessary to use a self-stabilizing gimbal to cooperate with the aerial photography equipment;

[0006] 4) Most drones equipped with cameras cannot focus manually, and the captured images cannot be fully zoomed according to our requirements, and cannot provide satisfactory monitoring images;

[0007] 5) The flight height of UAVs on the market is mostly measured according to atmospheric pressure. Weather factors have a great influence, and errors are prone to occur. They rarely carry obstacle avoidance devices, and their safety needs to be improved.

[0008] Most of the drones in the existing market are involved in aerial photography, plant protection, and surveying and mapping, which cannot meet the application requirements well

As a result, every time it is used, the cruise capability is insufficient, the operation is cumbersome, and the cost increases. It is not convenient for long-term power line inspection, and it is not easy to carry
