Unmanned aerial vehicle for power line patrol

Abstract

The invention belongs to the technical field of unmanned aerial vehicles, and particularly relates to an unmanned aerial vehicle for power line patrol. The unmanned aerial vehicle comprises a unmannedaerial vehicle body, connecting rods and supporting rods, wherein the bottom of the unmanned aerial vehicle body is fixedly connected with two symmetrically-distributed fixed rods; connecting sleevesare fixedly connected to the fixed rods; supporting frames are fixedly connected to the ends, away from the unmanned aerial vehicle body, of the fixed rods; the connecting rods are fixedly connectedto the two ends of the supporting frames; mounting sleeves are fixedly connected to the bottoms of the connecting rods; and first lengthening rods are detachably connected to the outward sides of themounting sleeves. According to the invention, a first annular snow removing knife and a second annular snow removing knife with proper sizes can be selected to clamp a high-voltage line, then the unmanned aerial vehicle is controlled to move along the high-voltage line so as to sweep off accumulated snow on the high-voltage line in time and prevent snow from being accumulated on the high-voltage line; and thus, the situation that the accumulated snow on the high-voltage line is iced to wrap the high-voltage line to increase the dead weight of the high-voltage line is prevented, and the high-voltage line and a high-voltage tower are prevented from being snapped and crushed due to the fact that the high-voltage line and the high-voltage tower are overwhelmed.

[0002] Unmanned aircraft, referred to as "UAV", is an unmanned aircraft operated by radio remote control equipment and its own program control device. With the continuous improvement of social industry and domestic electricity demand, the length of power transmission lines in my country is also increasing Rapid growth. According to incomplete statistics, the total mileage of my country's power transmission lines has reached 1.61 million kilometers in 2014. According to the current development speed, it is expected to exceed 1.8 million kilometers in 2020. Most of the inspections of these lines are carried out by drones. However, the existing inspection drones have a serious lack of adaptability to the terrain, especially when used on mountain slopes, operators need to work hard to open up a flat take-off and landing field, which is very inconvenient to use and greatly It increases the labor intensity of the operator, and at the same time, the drone can only take off and land at a fixed location, and cannot move with the operator, which reduces the inspection efficiency of the drone and violates the original intention of using the drone for inspection

[0003] Therefore, the Chinese patent discloses a power line inspection UAV with the application number (201920956864.9). This patented technology can reduce the operational difficulty and labor intensity of operators, and improve the inspection efficiency of electric power inspection in mountainous areas. However, the device It is impossible to clear the snow on the high-voltage line. If the snow cannot be removed in time, it may freeze on the high-voltage line and increase the load on the high-voltage line, which may lead to the risk of the high-voltage line being overwhelmed and broken.
