Multi-rotor-wing automatic positioning detector used for transmission line

Abstract

The invention relates to a multi-rotor-wing automatic positioning detector used for a transmission line. A patrol nacelle of the detector is fixedly connected with a multi-rotor-wing micro air vehicle by a connection structure; a master control board is fixed on the airframe of the multi-rotor-wing micro air vehicle; a power supply module is fixed on the patrol nacelle; a crawling mechanism is formed by a power device fixed on a side arm of the patrol nacelle and idler wheels connected with the power device; the master control board controls the power supply module to supply power for a driving mechanism of the multi-rotor-wing micro air vehicle or the power device of the crawling mechanism; an infrared video camera and a visible light camera are arranged on the inner wall of the patrol nacelle; the visible light camera is used for shooting the transmission line and the ambient environments and transmitting the information of the shot images to a ground station system by the master control board in real time; and the infrared video camera is used for detecting faults of the transmission line and transmitting the fault information to the ground station system by the master control board in real time. The multi-rotor-wing automatic positioning detector can be used in fields, has the advantages of high working efficiency and good safety, and has a real-time visual patrol function.

Description

technical field [0001] The invention relates to inspection equipment for ultra-high voltage transmission lines, in particular to a multi-rotor automatic positioning detector suitable for inspection of transmission lines. Background technique [0002] Power transmission must rely on high-voltage transmission lines. Its safe and stable operation directly affects the reliability of the power system. Due to the wide distribution of transmission lines, for example, when high-voltage transmission lines cross large-scale reservoirs, lakes and mountains, high altitudes, The complex geographical environment in the heavy ice area brings great difficulties to line maintenance. However, power lines and tower accessories have been exposed to the wild for a long time, and due to continuous mechanical tension and material aging, strands will be broken and worn. Corrosion and other damage, if not repaired and replaced in time, the original small damage and defects may expand, eventually le...

Problems solved by technology

Human line inspection is inefficient, labor-intensive, and limited by the natural environment; vehicle inspection is limited by ground traffic, and vehicle inspection cannot be realized in many places; helicopter inspection is expensive, and it is difficult to achieve the required inspection accuracy ; Although the robot patrols the line through its own joints to move over obstacles, although it solves the problem of unsafe manual work, the obstacle surmounting process is more complicated, the robot has many joints, the structure is complex, and the weight is heavy, so it is very inconvenient to operate.
