Unmanned aerial vehicle mounted flaming device with adjustable jetting direction and obstacle clearing unmanned aerial vehicle

Abstract

The invention provides an unmanned aerial vehicle mounted flaming device with an adjustable jetting direction and an obstacle clearing unmanned aerial vehicle. When the device is used for processing acompressed air line hanging object in a distribution network frame, a spraying angle and a spraying range are more flexible and wider. For an intermediate line hanging object of complex same-tower multi-loop erection, existing flaming operation is difficult to deeply clean. In the invention, a spray pipe can be adjusted to be at a vertical downward angle to effectively carry out flaming cleaningon the hanging objects under a working condition, a flaming defect elimination blind area is filled up, fault processing efficiency is greatly improved, and power supply reliability is guaranteed.

Description

technical field [0001] The invention relates to the technical field of high-voltage transmission line inspection, and more specifically, to an unmanned aerial vehicle with an adjustable injection direction and a fire-injecting device mounted on it and an obstacle-clearing unmanned aerial vehicle. Background technique [0002] With the continuous development of the power industry, the construction of medium-voltage overhead lines in distribution networks is becoming more and more extensive. There are a large number of medium-voltage overhead lines in distribution networks in various places, and the operating environment is complex.

[0002] With the continuous development of the power industry, the construction of medium-voltage overhead lines in distribution networks is becoming more and more extensive. There are a large number of medium-voltage overhead lines in distribution networks in various places, and the operating environment is complex. Coupled with the impact of harsh conditions such as typhoons in coastal areas, medium-voltage overhead lines There are often various floating objects, such as fishing lines, balloons, advertising banners, bird nests, etc.; on the one hand, the floating objects swing due to the influence of wind and gravity, which can easily cause phase-to-phase or phase-to-ground short-circuit trips, causing power outages; On the one hand, it is difficult to remove the floating objects due to the high height of the line and the live operation of the line

[0003] When distribution network operation and maintenance personnel deal with floating objects on medium-voltage lines, the traditional methods mainly adopt the following two methods: one is to clean up the power outage by climbing the tower. The traditional method has a long processing cycle, high labor intensity, and low safety factor. Affect the reliability of power supply and cause huge losses; the second is the cleaning of traditional fire-breathing drones with live operations. When dealing with floating objects on the complex line of multi-circuit line lights on the same tower, due to the limitation of angle and spraying distance, the clearing operation cannot be completed

In addition, traditional fire-breathing UAVs often need to adjust the attitude of the aircraft to adjust the angle of the spray gun. However, due to environmental factors such as wind and magnetic fields, it is often difficult for UAV pilots to fine-tune the UAV attitude accurately, and it is easy to adjust too much and cause no accident

[0004] The patent with the application number 201721173601.8 provides a solution with adjustable spray angle, but it is still difficult to deal with the complicated floating objects in the middle line erected by multiple circuits on the same tower, and there are many blind spots for spraying fire to eliminate defects
