In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention are described in further detail below with reference to the accompanying drawings.
In the prior art, the unmanned aerial vehicle carries an insulating rope and hangs the insulating rope on a conductor, then the insulating rope pulls a semi-static rope to be pulled to the conductor, and finally the semi-static rope lifts live working personnel or tools to a maintenance operation area. However, this method is suitable for carrying operators and/or working tools into the area to be overhauled, and cannot complete unmanned transmission line overhaul operation.
In addition, the device and the method for installing the pulley insulating rope on the high-voltage line unmanned aerial vehicle realize the installation of the pulley insulating rope on the high-voltage line under manual control, and people do not need to be specially arranged to climb a tower or even put on the line to place a lifting point when encountering potential safety hazards in the line loading and unloading process when the high-voltage line is maintained by using the maintenance robot, and a structure responsible for loading and unloading the line does not need to be additionally arranged by depending on a tower. However, this method is only used for installing the pulley insulating rope.
At present, unmanned aerial vehicles are increasingly widely used in the process of auxiliary maintenance operation. The task mounting that different operation types used is different, and its weight and structure all differ, and unmanned aerial vehicle size of a dimension and load-carrying capacity all have the difference in addition, and unmanned aerial vehicle actual flight in-process task mounting and unmanned aerial vehicle focus equilibrium, with equipment safe distance control etc. do not yet relate to, have influenced operation safety, it is big that the unmanned aerial vehicle of remote control develops the instrument and arranges the degree of difficulty in addition, has influenced unmanned aerial vehicle auxiliary operation and has developed.
Fig. 1 shows a flowchart of a method for assisting the operation of a power transmission line unmanned aerial vehicle according to an embodiment of the invention.
As shown in fig. 1, in step S101, before the unmanned aerial vehicle takes off, the mission tool is mounted on the unmanned aerial vehicle through the gravity center dynamic balancing device based on the requirement of the auxiliary work, so as to ensure that the gravity center of the mission tool and the gravity center of the unmanned aerial vehicle are maintained in the same direction.
Specifically, the gravity center dynamic balance device is shown in fig. 2 and comprises a mechanical interface 201 for interfacing with the unmanned aerial vehicle, a gyrostabilizer 202 and a mounting interface 203 for adapting to a task tool. Generally, the mechanical interface 201 can be connected to various kinds of drones, and the invention does not limit the interface type of the mechanical interface 201. The gyro stabilizer 202 can still make the connected carrier keep relatively stable in the original direction when being impacted by the outside.

Generally, the task tool includes a pulling rope winding and unwinding device, a water repellency detecting device, a flame projecting device, and the like.
As shown in fig. 1, in step S102, after the unmanned aerial vehicle takes off, the distance between the unmanned aerial vehicle and the surrounding object is measured in real time, the measured distance is compared with the safety distance, and when the distance approaches the safety distance, a prompt is sent to ensure that the distance is always greater than the safety distance.
Specifically, the safety distance is determined according to the voltage level of the power transmission conductor and the conductor installation manner, for example, the minimum safety distance for unmanned aerial vehicle flight at each voltage level is shown in tables 1-2 below.
TABLE 1 theoretical minimum safety distances for different AC voltage classes and minimum safety distances for practical operation
| AC voltage class (kV) | Theoretical minimum safe distance (m) | Minimum safe distance (m) for practical work |
| 500 | 3.0 | 5 |
| 750 | 4.0 | 6 |
| 1000 | 5.5 | 7.5 |
Generally speaking, the theoretical minimum safe distance is calculated under an ideal environment, the actual operation minimum safe distance is slightly larger than the theoretical minimum safe distance through experimental research, a range of 2m is added on the basis of the existing theoretical minimum safe distance in consideration of certain degree of predictability to serve as the actual operation minimum safe distance, and the actual requirements can be met through experimental verification.

| DC voltage class (kV) | Theoretical minimum safe distance (m) | Minimum safe distance (m) for practical work |
| ±500 | 4.0 | 6 |
| ±660 | 6.0 | 8 |
| ±800 | 8 | 10 |

Generally, the safe distance is determined before the current auxiliary operation task is executed, and what the unmanned aerial vehicle needs to do during the operation flight process is to measure the distance between the unmanned aerial vehicle and the surrounding object in real time, and specifically, the distance measurement mode includes, but is not limited to, laser distance measurement, double-sided visual distance measurement or ultrasonic distance measurement.

Specifically, in actual operation, the screw 602 is driven by the micro motor, when the screw grows, the spring 501 is pulled up, and the clamp 601 is opened; when the lead screw 602 is shortened, the spring 501 is normal, and the clamp 601 is closed. The unmanned aerial vehicle puts down duckbilled 503 through the haulage rope, and when the transmission line touched pressure sensitive sensor 502, spring 501 released, duckbilled 503 closed fixed the transmission line.
In one embodiment, after establishing the connection between the drone and the power conductor through step S103, the auxiliary equipment placement is completed by the tool placed on the duckbill.
In one embodiment, when the auxiliary work is completed, the task tool is retracted by the retraction device connected to the pull-cord, i.e. the retraction sequence is reversed from the method steps in fig. 1.
