Description

TECHNICAL FIELD

[0002] With the development of China's industry, the rapid increase in the mileage of electrified railways, and the continuous rise in residential electricity consumption, the capacity and voltage of the power supply network are also increasing accordingly, which requires the power supply system to have higher safety and stability. In the power supply system, high-voltage insulators are an important component, and their maintenance condition is very important for the safe operation of the line. Due to long-term exposure to the environment, a layer of conductive dirt will form on the surface of the insulator, which can cause accidents such as pollution flashover, posing a great threat to the normal operation of the power grid.

[0003] Common insulator surface treatment methods include: mechanical method, which removes the substances attached to the surface of the insulator by mechanical means, such as using a scraper or grinding method; chemical method, which uses chemicals to dissolve the deposits or generate other forms of substances that are easy to clean or discharge, for example, using hydrochloric acid or sulfuric acid to clean the surface of the insulator in a corrosive environment, which can remove most of the dirt and rust; physical method, including high-pressure water gun cleaning, sandblasting, etc., high-pressure water gun can flush away the particles deposited on the surface of the insulator, and sandblasting can completely remove the dirt and rust layer.

[0004] However, the mechanical method can effectively remove most of the substances attached to the surface of the insulator, but there will still be some sticky and firm attachments and particles embedded in the pores on the surface of the insulator, which cannot be completely removed by this method.

[0045] When the insulator needs to be cleaned, the unmanned aerial vehicle 1 adopts the FlyCart 30, first makes the unmanned aerial vehicle 1 move to the position close to the insulator, and makes the spray gun 8 and the ducted fan 9 be located below the insulator, then drives the movement of the second adjusting plate 5 under the movement of the adjusting winding assembly 13, the second adjusting plate 5 drives the movement of the steering plate 6, thereby driving the movement of the spray gun 8 and the ducted fan 9, adjusts the position of the spray gun 8 and the ducted fan 9, moves the spray gun 8 and the ducted fan 9 to the appropriate cleaning position, adjusts the movement of the winding assembly 13, drives the synchronous rotation of the winding wheel 12, the winding wheel 12 corresponds to the winding or unwinding of the water pipe 11, facilitates the movement of the water pipe 11 following the movement of the spray gun 8, avoids the winding and scattering of the water pipe 11 due to looseness, avoids affecting the spray cleaning of the spray gun 8, then drives the rotation of the steering plate 6 under the cooperation of the steering assembly 7, the steering plate 6 drives the rotation of the spray gun 8 and the ducted fan 9, adjusts the angle of the spray gun 8 and the ducted fan 9, makes the flushing angle greater than or equal to 60°, and then flushes the insulator from bottom to top, then under the work of the high-pressure water pump 10, the high-pressure water pump 10 adopts a high-pressure plunger pump with a pressure greater than 10 MPa, a flow of 12 L / min, and a weight less than 5 kg, the sprayed high-pressure water column can reach more than 3 meters, and the water pipe 11 adopts a 2cm high-pressure water pipe, ensures sufficient flow and water pressure, can pump out the water in the water tank 3, the water tank 3 adopts a large capacity of 35L, and a water inlet is arranged on one side of the water tank 3 for input of the flushing water, the flushing water adopts industrial distilled water, and the electrical conductivity is 0.1μs / cm, and the resistivity is 10000 kΩ·cm. The water is delivered to the spray gun 8 through the water pipe 11, facilitating the cleaning of the insulator. After the cleaning is completed, the duct fan 9 is turned on. The duct fan 9 is a 90 mm high-speed duct fan, which can generate a thrust of 6-8 kg during operation. The residual water droplets can be blown dry at a distance of 2-3 meters from the insulator. At the same time, the electric heating wire 14 in the duct fan 9 starts to work. The electric heating wire 14 is distributed in a ring shape in the duct fan 9, which facilitates the uniform blowing of hot air, thereby facilitating the rapid air drying of the insulator. Dust screens 15 are arranged at the openings of the two ends of the duct fan 9, which are used for dustproof protection of the duct fan 9, avoiding dust from floating into the inside of the duct fan 9 and affecting the blowing. When the surface of the dust screen 15 adheres to a large amount of dust, the rotation of the rotating assembly 16 drives the rotation of the rotating plate 17 and the cleaning brush 18. When the rotating plate 17 and the cleaning brush 18 are upwardly rotated and contacted with the dust screen 15, the switch assembly 22 controls the liquid supply assembly 21 to work, and sprays cleaning agent on the dust screen 15, and cooperates with the cleaning brush 18 to clean. When the rotating plate 17 and the cleaning brush 18 are downwardly rotated and separated from the dust screen 15, the switch assembly 22 controls the liquid supply assembly 21 to stop working, thereby facilitating the automatic cleaning of the dust screen 15, avoiding the adhesion of dust to the dust screen 15 and affecting the blowing of the duct fan 9, facilitating the rapid air drying of the insulator, and improving the air drying efficiency of the insulator. The steering assembly 7, the spray gun 8, the duct fan 9, the high-pressure water pump 10, the adjusting and winding assembly 13, the electric heating wire 14, the rotating assembly 16 and other structures are remotely controlled through image transmission and communication of the Zhi Fei W330 platform.

[0046] Example Two

[0047] Referring to Figures 2-4The steering assembly 7 comprises support plates 701 fixed at the top end of the second adjusting plate 5, a first gear 702 rotatably connected between the two support plates 701, a first driving motor 703 fixed on one side of one of the support plates 701 and fixed with the first gear 702, a rack 704 slidably arranged at the top end of the second adjusting plate 5 and engaged with the first gear 702, a first sliding block 705 fixed at the bottom end of the rack 704, a first sliding slot 706 formed in the top end of the second adjusting plate 5 and through which the first sliding block 705 slides, a second sliding block 707 fixed at one end of the rack 704, a second sliding slot 708 formed in one side of the steering plate 6 and through which the second sliding block 707 slides, the water pipe 11 comprises a first high-pressure pipe 1101, a rotary joint 1102 and a second high-pressure pipe 1103, the rotary joint 1102 is fixed at one end of the winding wheel 12, the rotary joint 1102 is communicated with the high-pressure water pump 10 through the first high-pressure pipe 1101, one end of the second high-pressure pipe 1103 is wound around the outer wall of the winding wheel 12 and communicated with the rotary joint 1102, the other end of the second high-pressure pipe 1103 is communicated with the spray gun 8, the adjusting and winding assembly 13 comprises a lead screw 1301 rotatably arranged in the first adjusting plate 4 and threadedly connected with the second adjusting plate 5, a second driving motor 1302 fixed on one side of the first adjusting plate 4 and fixed with the lead screw 1301, a first bevel gear 1303 sleeved on the outer wall of the lead screw 1301, and a second bevel gear 1304 fixed at the bottom end of the winding wheel 12 and engaged with the first bevel gear 1303.

[0048] When the unmanned aerial vehicle 1 is in the air and the positions of the spray gun 8 and the ducted fan 9 need to be adjusted, first, the rotation of the lead screw 1301 is driven by the movement of the second driving motor 1302, and the second adjusting plate 5 is inserted and moved in the first adjusting plate 4, thereby driving the spray gun 8 and the ducted fan 9 to move closer to or farther away from the unmanned aerial vehicle 1. When moving closer, the rotation of the first bevel gear 1303 is driven by the lead screw 1301, and the rotation of the second bevel gear 1304 is driven by the first bevel gear 1303, thereby driving the rotation of the winding wheel 12. The winding wheel 12 winds the water pipe 11 during rotation. When moving farther away, the lead screw 1301 is reversed by the second driving motor 1302, and the winding wheel 12 is reversed by the cooperation of the first bevel gear 1303 and the second bevel gear 1304, thereby unwinding the water pipe 11. Thus, when the spray gun 8 moves, the water pipe 11 can be appropriately positioned relative to the spray gun 8, and the water pipe 11 is prevented from being wound and knotted when it is in a loose state, thereby preventing the water supply of the spray gun 8 from being affected. Specifically, the rotary joint 1102 is fixed on the end axis of the winding wheel 12, and one end of the rotary joint 1102 penetrates through the outer wall of the winding wheel 12 and extends out, and then the end is connected with the second high-pressure pipe 1103. The other end of the second high-pressure pipe 1103 is connected with the spray gun 8. Thus, when the winding wheel 12 rotates, the second high-pressure pipe 1103 is wound. The other end of the rotary joint 1102 is connected with the first high-pressure pipe 1101, and the end and the first high-pressure pipe 1101 are in a rotating state. Thus, the winding wheel 12 is prevented from pulling the first high-pressure pipe 1101 when it rotates. The other end of the first high-pressure pipe 1101 is connected with the high-pressure water pump 10. Thus, the high-pressure water pump 10 can deliver the water in the water tank 3 to the spray gun 8 through the first high-pressure pipe 1101, the rotary joint 1102, and the second high-pressure pipe 1103 in sequence. When the positions of the spray gun 8 and the ducted fan 9 are adjusted, the rotation of the first gear 702 is driven by the movement of the first driving motor 703, and the horizontal movement of the rack 704 is driven by the meshing of the first gear 702 and the rack 704. At the same time, the rack 704 is conveniently supported by the sliding cooperation of the first sliding block 705 and the first sliding groove 706, thereby maintaining the stability of the movement of the rack 704. The rack 704 drives the movement of the second sliding block 707, so that the second sliding block 707 slides in the second sliding groove 708. Thus, the rotation of the steering plate 6 is driven by the horizontal left-right movement of the rack 704, and the spray gun 8 and the ducted fan 9 are driven to rotate by the steering plate 6. The angle of the spray gun 8 and the ducted fan 9 is adjusted, so that the angle between the spray gun 8 and the ducted fan 9 and the second adjusting plate 5 is greater than or equal to 60°. Thus, the insulator can be washed from bottom to top, thereby facilitating the rapid cleaning of the insulator.
