Description

Technical Field

[0001] This invention relates to the field of insulator cleaning technology, and more specifically to an insulator cleaning device based on a drone. Background Technology

[0002] A drone is a self-powered, radio-controlled or autonomously flying unmanned aerial vehicle capable of performing multiple tasks and being reusable. An insulator is a special insulating control that plays an important role in overhead power transmission lines. The porcelain and glass insulators of overhead power transmission lines need to be cleaned and coated with antifouling cleaning liquid (PRTV) regularly, depending on the degree of surface dirt. Before spraying, drones are needed to perform simple cleaning of the insulators to improve cleaning efficiency.

[0003] Currently, after using a cleaning device to spray water, drones operating at high altitudes need to repeatedly take off and land to replenish the water supply, which affects the cleaning efficiency of insulators. In addition, the height of the nozzles and drying fans used for cleaning on drones is often inconvenient to adjust. In actual use, operators need to repeatedly operate the drone to change its position and align it with the insulators, which increases the difficulty of operation and affects the cleaning efficiency. Therefore, our technicians have provided a drone-based insulator cleaning device to solve these problems. Summary of the Invention

[0012] As a further description of the above technical solution: the drying mechanism includes a hot air blower, which is fixedly installed on the right side of the storage box. A gas supply pipe is fixedly connected to the right side of the storage box, and a synchronization pipe is rotatably connected to the right end of the gas supply pipe. The hot air blower is internally connected to the gas supply pipe. A transfer box is fixedly connected to the synchronization pipe, and a gear ring is fixedly connected to the outer ring of the synchronization pipe.

This can maintain the stability of the drone while completing the drying operation of the cleaned insulator. At the same time, it reduces the difficulty of personnel operating the drone. There is no need to repeatedly move the drone and the insulator to a suitable angle and distance, which reduces the difficulty of cleaning the insulator. Attached Figure Description

The other end of the return pipe 18 passes through and extends into the interior of the return box 11.

[0029] The drying mechanism 13 includes a hot air blower 1301, which is fixedly installed on the right side of the storage box 2. A gas supply pipe 1302 is fixedly connected to the right side of the storage box 2. A synchronization pipe 1303 is rotatably connected to the right end of the gas supply pipe 1302.

A movable groove 1309 is provided on the sealing strip 1308, and a synchronous pipe 1303 is located inside the movable groove 1309.

The outer ring of the sealing strip 1308 is slidably connected to the inner wall of the transfer box 1304. The sealing strip 1308 can be limited.

[0030] Mounting frame 1 is installed at the cleaning position of the drone. The user fills the storage box 2 with water, and then the insulator in the high altitude can be cleaned. The drone carries mounting frame 1 to fly smoothly to the left side of the insulator. Image acquisition device 7 acquires images of the insulator and the space below. The user controls the servo motor 8 to be powered on. After the servo motor 8 is powered on, it drives the screw fixedly connected to it to rotate synchronously. The collection box 6 threaded on the screw starts to move to the right towards the outside of the mounting groove 5 until the collection box 6 is at the bottom of the insulator.

[0031] The user controls the liquid pump 3 to be powered on. After the liquid pump 3 is powered on, the water inside the storage tank 2 is drawn into the pipe and sent to the rotating nozzle 4. The water flow from the rotating nozzle 4 is sprayed onto the insulator, causing the dust and attached impurities on the surface of the insulator to fall off. The water flow, mixed with dust and impurities, falls into the collection box 6 at the bottom due to gravity. At this time, the pipe port assembly 10 of the return pump 9 is always located inside the collection box 6. The user controls the return pump 9 to be powered on. The water inlet head 1002 generates suction to absorb the water flow inside the collection box 6 and sends it into the return box 11 through the return pump 9.

[0032] After the water flows into the return box 11 through the pipe, it moves downward under the force of gravity and comes into contact with the perforated filter plate 12. The dust and impurities in the water will be blocked and adsorbed by the perforated filter plate 12, and the water will pass through the tiny holes and be discharged into the storage box 2 to complete the return.

[0033] The electromagnetic plate 15 is set to work intermittently. The electromagnetic plate 15 generates magnetism to attract the metal plate 16 at the bottom. The metal plate 16 pulls the perforated filter plate 12 upward. Then, the electromagnetic plate 15 is de-energized and the perforated filter plate 12 falls under the action of gravity, causing collision vibration. This causes dust and impurities to move to the left along the inclined perforated filter plate 12 into the processing box 17 until they enter the processing box 17. At this time, the processing box 17 collects the dust and impurities. Meanwhile, the drain plate 20 causes some of the introduced water to flow downward through the return pipe 18 into the return box 11, thereby completing the return and preventing the water from staying inside the processing box 17, which would require the processing box 17 to be replaced multiple times.

[0034] After cleaning, the servo motor 8 is manually controlled to pull the collection box 6 into the mounting slot 5. Then, the drive motor 1306 and the electric guide rail 1312 are powered on by the manual control. After the drive motor 1306 is powered on, it drives the gear fixedly connected to it to rotate synchronously. The gear ring 1305 makes the transfer box 1304 start to rotate synchronously. The electric guide rail 1312 pulls the jet pipe 1311 to move. At this time, the jet pipe 1311 moves inside the through slot 1310 and pulls the sealing strip 1308. The sealing strip 1308 moves around the synchronous wheel 1307 to achieve sealing. At this time, the drone keeps the jet pipe 1311 stable and can reach any specified position within the range. After reaching the front of the insulator, the hot air blower 1301 operates. The airflow enters the air supply pipe 1302 through the pipe, and then enters the interior of the transfer box 1304 through the connected synchronous pipe 1303. The heat flow is restricted by the sealing strip 1308 and is sprayed out through the jet pipe 1311 to complete the drying of the insulator.

[0035] In this invention, a movable collection box 6 is used to collect water sprayed onto the surface of the insulator. The collected water is then filtered through a return box 11. The filtered water is returned to the storage box 2 for reuse, thereby improving the cleaning efficiency of the drone-based insulator cleaning device. The high-altitude drone can extend the operation time and reduce the cycle of taking off and landing to replenish water. The return box 11 is equipped with a perforated filter plate 12 that can generate vibration and a processing box 17, which can collect dust and impurities on the perforated filter plate 12 to prevent clogging, thus working in conjunction with extending the drone's operating time.

[0036] By setting up a drive motor 1306 in conjunction with gears to drive the transfer box 1304 to rotate, the electric guide rail 1312 can drive the jet pipe 1311 to move. The sealing strip 1308 set inside the transfer box 1304 can keep the inside of the transfer box 1304 sealed in real time when the jet pipe 1311 moves, so that the heat flow entering the transfer box 1304 can only overflow through the jet pipe 1311. At this time, the drone can maintain stability and the jet pipe 1311 can reach any specified position. This keeps the drone stable while completing the drying operation of the cleaned insulator. At the same time, it reduces the difficulty of operating the drone by personnel, eliminating the need to repeatedly move the drone to maintain a suitable angle and distance from the insulator, thus reducing the difficulty of cleaning the insulator.

[0037] Please see Figure 2 In this case, a large-size filter plate 14 is connected to the inner wall of the mounting groove 5, and the large-size filter plate 14 is located on the right side of the pipe assembly 10.

[0038] In this invention, the large-size filter plate 14 can filter the water flowing into the collection box 6, preventing large impurities from entering the collection box 6 and clogging the pipe assembly 10 during the water recovery process.

[0039] Please see Figure 5 Among them, a guide rod 19 is fixedly connected to the inner wall of the mounting groove 5, and the collection box 6 is slidably connected to the guide rod 19.

[0040] In this invention, the guide rod 19 can restrict the collection box 6, so that the collection box 6 always maintains stable horizontal movement.
