Problems solved by technology

However, due to the huge number of line insulators, it will not be possible to replace them all within a long period of time. In addition, the online insulation detection of composite material insulators is even more difficult.

Embodiment Construction

[0032] The preferred embodiments will be described in detail below in conjunction with the accompanying drawings. It should be emphasized that the following description is only exemplary and not intended to limit the scope of the invention and its application.

[0033] figure 1 is a system schematic diagram of a flying robot used to inspect transmission line insulators. The flying robot used to detect the insulator of the transmission line is mainly composed of a three-axis aircraft or a four-axis aircraft, a flight control system and a target recognition system. Taking a quadcopter as an example, the brushless motor 1 controls the quadcopter to use the power difference of the four propellers to change the direction of motion. The component force of the combined lift generated by the four propellers in the horizontal direction determines the direction of navigation, and the component force in the vertical direction determines the direction of navigation. The force determines...

Abstract

The invention discloses a flying robot used for detecting transmission line insulator in the field of aircraft control and image transmission technique. The technical proposal is that the flying robot used for detecting the transmission line insulator consists of a three-axis aircraft or four-axis aircraft, a flying control system and an objective recognition system; the power part of the three-axis aircraft consists of three pairs of airscrews, three coaxial motors and three supporting arms; the power part of the four-axis aircraft consists of 4 direct-drive brushless motors and four airscrews; the flying control system consists of an on-board self-control system and a ground station control system; the objective recognition system consists of on-board mission load and a ground image processing system. By installing a precise navigation system on the flying robot, the flying robot exactly flies in the space above the insulator to be detected; by adopting the image gaining and transmission system, the zero-value insulator is exactly detected, the labor intensity is lightened, and the safety of the detection personnel is improved during the detection process.

Description

technical field [0001] The invention belongs to the technical field of aircraft control and image transmission, and in particular relates to a flying robot for detecting insulators of power transmission lines. Background technique [0002] Insulators are devices used to insulate and connect wires and iron towers on overhead high-voltage transmission lines, and are one of the most used insulators, especially for old lines. When there are low-value or zero-value insulators in the insulator string, flashover accidents are prone to occur in polluted environments, overvoltages and even working voltages. When the lightning overvoltage acts on the zero-value insulator, the zero-value insulator is completely broken down, and the strong lightning current and power frequency continuous current flow through the gap of the porcelain part of the zero-value insulator head, which will cause the zero-value insulator to overheat and explode. Therefore, zero-value insulators are a hidden dan...
