[0082] The present invention provides a method for live cleaning of power line insulators based on an unmanned aerial vehicle, comprising the following steps:

[0083] Step S1: Prepare work arrangements,

[0084] According to the work plan, organize staff to conduct on-site surveys, fill in safety measures and other safety precautions, clearly record insulators that are not suitable for cleaning, and determine staff based on the difficulty of on-site operations;

[0089] Table 1 Staff division of labor

[0090]

[0091]

[0092] Step S2: Re-inspection by the person in charge of the work,

[0093] Check line names and double numbers;

[0094] Check whether the on-site environment meets the requirements for non-power-off cleaning operations;

[0095] Check whether the line equipment and devices meet the requirements of non-stop operation, clarify the scope of cleaning equipment, and clearly mark and exclude the insulating equipment that does not meet the requirements of non-stop washing;

[0096] Check whether the meteorological conditions meet the requirements for live working;

[0097] Check whether the safety measures listed in the work ticket in step S1 are complete, and add safety technical measures if necessary.

[0098] Step S3: Arrange the work site,

[0099] Necessary safety fences and relevant warning signs should be set up at the work site. If there are important equipment or special protection required under the working airspace, reliable materials should be used for shielding and protection;

[0100] Safety tools, materials and cleaning equipment should be arranged in a safe and orderly manner as required.

[0101] Step S4: Safety tools, materials and cleaning equipment inspection,

[0102] Check the appearance of the cleaning equipment. The cleaning equipment should be free of deformation and damage, and the basic operation should be flexible.

[0103] Safety tools should be fully qualified;

[0104] Check whether the material quantity and model are appropriate.

[0105] Step S5: Check and confirm again that the safety measures are complete and the safety fences set up in the operation area meet the requirements. Specifically, the safety fences set up below the operation area should ensure that there are no personnel or vehicles within the range of cleaning liquid dripping, drone takeoff and landing, or malfunction falling during the cleaning operation, so as not to be affected by the operation.

[0106] At the same time, the setting of safety measures should also fully consider the actual on-site working environment and meteorological environment, and make flexible and reasonable arrangements.

[0107] Step S6: After the drone takes off, test spraying is carried out in a suitable open area to confirm that the equipment can be operated reliably and flexibly.

[0108] The test spraying area should be selected in an area where the surrounding environment and people in the space below are not affected by the spraying cleaning agent.

[0109] The pressure and direction of the drone spray should ensure that the insulation is thoroughly cleaned while avoiding physical damage to the insulation material.

[0110] Among them, the vertical distance between the drone's take-off point and the wire should not be less than 8 meters, and there should be no obstructions within a 6-meter radius of the take-off point. After reaching the corresponding height of the tower, it should fly towards the tower.

[0111] Step S7: Use a drone to perform visible light appearance inspection and infrared temperature measurement on the pre-cleaning equipment. If insulation equipment has obvious visible cracks, it should not be cleaned without power outages. If equipment has abnormal temperatures, it should not be cleaned without power outages.

[0112] Step S8: Perform cleaning operations. During the operation, the minimum distance between the operating tool, i.e., the drone, and the insulating equipment should be greater than or equal to 0.7 meters to prevent equipment failure caused by insufficient safety distance.

[0113] The cleaning process includes the following steps:

[0114] Fly to the operation point according to the preset route;

[0115] Adjust the height and attitude of the drone to ensure that the high-voltage nozzle is aimed at the insulation equipment;

[0116] Start the cleaning system of the drone and flush the insulating equipment according to the established pressure and flow. During the flushing process, the aerial guardian monitors the flushing operation and the status of the insulating equipment in real time, and promptly issues reminders and stops any abnormalities.

[0117] For insulating equipment with a lot of dust accumulation, a single atomization method can be used for flushing by remotely adjusting the water pressure of the remote-controlled insulating water spray gun; for salt-alkali crystallization solidification or other solidified attachments with high viscosity, high-pressure water column flushing can be performed first, and then water mist flushing can be performed by remotely adjusting the water pressure of the remote-controlled insulating water spray gun.

[0118] Among them, during the cleaning operation in step S8, the following precautions are included:

[0119] The floor should be washed piece by piece from bottom to top, leaving no dead corners, first washing the downwind side and then the upwind side;

[0120] During the flushing process, pay attention to infrared imaging and handle any abnormalities promptly;

[0121] During the cleaning process, be sure to keep a safe distance from the insulating equipment being washed and surrounding objects;

[0122] If there is important equipment or special protection required under the working airspace, reliable materials should be used for shielding and protection;

[0123] The staff stood on the upwind side to operate and wore masks.

[0124] When the staff investigated the actual situation on site, they found that the insulation equipment formed a sewage flow during operation and the surface leakage current increased. The following protective measures were required:

[0125] 1. Flush from bottom to top in strict accordance with the order required by the flushing method technical specifications.

[0126] 2. Plan the flight route and flushing angle before flushing, and test and adjust the spray gun pressure and direction.

[0127] 3. Try to avoid splashing liquid onto nearby equipment to prevent flashover of nearby insulators in the splashing liquid mist.

[0128] 4. Pay attention to the liquid flow and infrared monitoring data during operation, and deal with any abnormalities in a timely manner.

[0129] In addition to the above necessary fixing steps, the following steps can be added according to the actual situation on site:

[0130] Specifically, it includes step S9 and step S10,

[0131] Step S9:

[0132] After the cleaning is completed, the person in charge of the work will conduct a comprehensive cleanliness inspection and record the cleaning effect, specifically record the problems found during the process, and adjust the cleaning parameters or the position of the drone according to the inspection results.

[0133] After cleaning, the cleaned insulating equipment is left with clear reagents and the surface of the insulating equipment is bright or has no residual stains, which means it is clean. Monitor the cleaned equipment on site for 15 minutes, and clear the site if there is no abnormality. After 12 hours after the operation is completed, conduct a special inspection of the cleaned equipment.

[0134] Record any deficiencies due to on-site environmental conditions or special contamination issues. After the operation is completed, special supplementary cleaning will be carried out using the insulating rod method to ensure that the insulating equipment is clean.

[0135] Step S10:

[0136] After the operation is completed, the work leader organizes the team members to clean up the tools and the site, put the drone and supporting equipment in the storage box, and inspect and clean the site. After there is no residue left, the site is evacuated. Personnel are prohibited from staying alone at the site or returning to the work site.

[0137] Also comprising step S11:

[0138] During the cleaning process, pay attention to the remaining amount of detergent and battery. If you find an alarm for detergent or battery power, return to the destination in time to replenish or replace it while ensuring safety. The replaced battery should be charged in time to ensure battery life and continuity of work. Wear gloves when adding cleaning fluid.

[0139] A live cleaning device for power line insulators based on drones.
