Description

Technical Field

[0001] The invention relates to the technical field of circuit maintenance, in particular to an insulator string surface cleaning device. Background Art

[0002] Transmission lines are key facilities in power systems that transmit electrical energy from power plants to various power consumption areas. It consists of conductors, towers, brackets, insulators, etc., and is mainly responsible for efficient and stable transmission of electricity. The insulator string is a key component used to suspend and support the conductors in the transmission line. It can prevent the conductors from short-circuiting with the tower and withstand the mechanical tension of the line. It is usually composed of multiple ceramic or composite insulators in series, with excellent electrical insulation performance and mechanical stress resistance. Due to the influence of external environmental pollution, dust, salt spray and other factors, dust easily accumulates on the surface of the insulator, reducing the insulation performance and even causing discharge failures. Therefore, the cleaning and maintenance of the insulator string is an important task to ensure the normal operation of the transmission line, and regular cleaning of the insulator string is a necessary measure to ensure the reliability and safety of the transmission line.

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] Embodiment 1: This embodiment provides an insulator string surface cleaning device, specifically, Figure 1-Figure 4 , Figure 8-Figure 10 As shown, it includes a drone 1, on which a cleaning assembly 2 is mounted; the drone 1 includes a fuselage frame 113, on which a water tank 105 and a plurality of swing arms 106 are arranged, on which a flight motor 112 is mounted, on which a wing 102 is arranged, and on which a plurality of support legs 103 are arranged. The water tank 105 is loaded with cleaning water for flushing insulators, the support legs 103 are used to support the drone 1, the swing arms 106 are used to support the flight motor 112, and the flight motor 112 drives the wing 102 to control the take-off and landing of the drone 1.

[0032] The cleaning assembly 2 includes a mounting plate 206, which is mounted on the fuselage frame 113. A driving unit and an adjusting unit are arranged on the mounting plate 206. The driving unit is provided with a cleaning unit, and the adjusting unit is used to control the position of the cleaning unit. The driving unit is used to start the cleaning unit to clean the surface of the insulator string, and the adjusting unit is used to adjust the position of the cleaning unit to achieve embracing and giving way and cleaning operations on insulator strings of different sizes.

[0033] The driving unit includes a plurality of second gears 209 rotatably connected to the mounting plate 206, and also includes a first adjusting arm 208, a third adjusting arm 212, and a second adjusting arm 211, wherein the first adjusting arm 208, the second adjusting arm 211, and the third adjusting arm 212 are all rotatably connected with a third gear 210, and the first adjusting arm 208, the second adjusting arm 211, and the third adjusting arm 212 are respectively rotatably connected to different second gears 209, and the third gear 210 is meshed with the second gear 209; a driving motor 204 is installed on the mounting plate 206, and the driving motor 204 is transmission-connected to a second gear 209, and a belt 213 is provided on the mounting plate 206, and the belt 213 is sleeved on a plurality of second gears 209.

[0034] Start the driving motor 204, which drives a second gear 209. The second gear 209 drives the remaining second gears 209 through the belt 213, so that multiple second gears 209 rotate synchronously and in the same direction. The second gear 209 drives multiple third gears 210 to rotate synchronously respectively. The third gears 210 are used to drive the cleaning unit.

[0035] The cleaning unit includes a first cleaning head 202, which is fixedly connected to the third gear 210. The first cleaning head 202 is provided with a plurality of flushing holes 218 and a cleaning brush strip 216. The water tank 105 is provided with a plurality of water hoses 207, which are connected to the first cleaning head 202.

[0036] When the third gear 210 rotates, it drives the first cleaning head 202, and at the same time, the cleaning water in the water tank 105 flows into the first cleaning head 202. Therefore, the first cleaning head 202 rotates and sprays cleaning water, and at the same time, the cleaning brush strip 216 cleans the surface of the insulator string to improve the cleaning effect.

[0037] The adjusting unit includes a first adjusting link 201 and a second adjusting link 219 rotatably connected to a third adjusting arm 212, the second adjusting link 219 is rotatably connected to the second adjusting arm 211, and the first adjusting link 201 is rotatably connected to the first adjusting arm 208; and also includes an adjusting motor 203 installed on the mounting plate 206, and the adjusting motor 203 is transmission-connected to the first adjusting arm 208.

[0038] Start the adjusting motor 203, and the adjusting motor 203 drives the first adjusting arm 208 to rotate. When the first adjusting arm 208 rotates, the third adjusting arm 212 is pushed to rotate through the first adjusting link 201, and the third adjusting arm 212 further pushes the second adjusting link 219 to rotate the second adjusting arm 211, thereby realizing the synchronous rotation of the first adjusting arm 208, the second adjusting arm 211, and the third adjusting arm 212 to adjust the position of the cleaning unit.

[0039] When cleaning the insulator string, the staff remotely starts the flight motor 112, at which time the wing 102 starts to rotate, and the drone 1 starts to take off. When the drone 1 approaches the insulator string, the adjustment motor 203 starts, and at this time, multiple cleaning units start to move away from each other, and then the insulator string enters from the opening of the fuselage frame 113 and the mounting plate 206. Then the adjustment motor 203 is controlled to reverse, and at this time, multiple cleaning units start to move closer to achieve the positioning of the insulator string, ensuring that the insulator string is coaxial with the fuselage frame 113 and the mounting plate 206. Then the drive motor 204 is started, and the power of the drive motor 204 is transmitted to the first cleaning head 202. The first cleaning head 202 starts to drive the cleaning brush strip 216 to rotate and clean the surface of the insulator string. At the same time, the water pump in the water tank 105 starts to spray water from the flushing hole 218 to flush the surface of the insulator. As the cleaning operation proceeds, the drone 1 starts to slowly descend so that the cleaning unit cleans all positions of the insulator string one by one until the insulator string is cleaned. Then, the water spraying is stopped, the driving motor 204 stops rotating, and the regulating motor 203 is started, so that the cleaning units are in operation, the drone 1 is moved away from the insulator string, and then the drone 1 can be retracted.

[0040] Embodiment 2: This embodiment is further expanded on the basis of the above embodiment. Fig.10 , Fig.11 As shown, the first cleaning head 202 is rotatably connected to the second cleaning head 215, the water hose 207 is connected to the second cleaning head 215, the second cleaning head 215 is fixedly connected to the support frame 214, the support frame 214 is installed on the first adjusting arm 208 or the second adjusting arm 211 or the third adjusting arm 212, and the second cleaning head 215 is provided with a guide hole 217; the water in the water tank 105 enters the second cleaning head 215 through the water hose 207, then passes through the guide hole 217, and finally sprays out from the flushing hole 218.

[0041] The cleaning water flows from the water supply hose 207 to the second cleaning head 215. Since the support frame 214 limits the second cleaning head 215, when multiple cleaning units are close to the insulator string, the direction of the guide hole 217 is just aligned with the insulator string. At this time, the guide hole 217 will only supply water to the flushing hole 218 facing the insulator string. Therefore, when the cleaning brush strip 216 cleans the surface of the insulator string, only the flushing hole 218 facing the insulator string will spray water back, thereby preventing unnecessary consumption of water and improving working endurance.

[0042] The other parts of this embodiment are the same as those of the above embodiment and will not be described in detail.

[0043] Embodiment 3: This embodiment is further expanded on the basis of the above embodiment. Fig. 9As shown, the mounting plate 206 is rotatably connected to a detection arc ring 205, the detection arc ring 205 is meshed with a plurality of second gears 209, and a visual detection device for observing the surface condition of the insulator is arranged on the detection arc ring 205.

[0044] When the multiple second gears 209 rotate, the second gears 209 will also drive the detection arc ring 205 to rotate. The rotation of the detection arc ring 205 will drive the visual inspection equipment to surround the insulator string. As the cleaning operation proceeds, the drone 1 will also move downward from the top of the insulator string, so as to achieve the visual inspection equipment to obtain all-round images of the insulator string, thereby improving the accuracy of the detection.

[0045] The other parts of this embodiment are the same as those of the above embodiment and will not be described in detail.

[0046] Embodiment 4: This embodiment is further expanded on the basis of the above embodiment. Figure 5 As shown, the fuselage frame 113 is rotatably connected to the retracting and releasing arc circle 108, and a retracting and releasing motor 110 is provided on the fuselage frame 113. A first gear 109 is installed on the retracting and releasing motor 110, and the retracting and releasing arc circle 108 is meshed with the first gear 109. The retracting and releasing arc circle 108 is rotatably connected to a plurality of pull rods 111, and the pull rods 111 are rotatably connected to the swing arm 106.

[0047] Before the cleaning operation, the retractable motor 110 is started, the retractable motor 110 drives the first gear 109 to rotate, the first gear 109 drives the retractable arc 108 to rotate, the retractable arc 108 pushes the pull rod 111 when rotating, the pull rod 111 pushes the swing arm 106, at this time the swing arm 106 drives the flight motor 112 away from the fuselage frame 113; after the cleaning operation, the retractable motor 110 is reversed, at this time the swing arm 106 drives the flight motor 112 close to the fuselage frame 113. In this way, the retractable and retractable wings 102 are realized, on the one hand, the overall size of the drone 1 is reduced by retracting and retracting, the space occupied is reduced, and it is convenient for transportation; on the other hand, the probability of the wings 102 and the swing arm 106 being hit is reduced to prevent them from being deformed and damaged.

[0048] The other parts of this embodiment are the same as those of the above embodiment and will not be described in detail.

[0049] Embodiment 5: This embodiment is further expanded on the basis of the above embodiment. Figure 4 As shown, a first protective top cover 101 is installed on the retractable arc circle 108, and a second protective top cover 107 is rotatably connected to the first protective top cover 101.

[0050] Before the cleaning operation, manually move the second protective cover 107 so that the second protective cover 107 completely overlaps with the first protective cover 101, so that the insulator string can enter the drone 1; after the cleaning operation, move the second protective cover 107 and rotate it relative to the first protective cover 101, so that the second protective cover 107 blocks the opening of the first protective cover 101. At this time, the first protective cover 101 and the second protective cover 107 jointly protect the folded wing 102 below.

[0051] The other parts of this embodiment are the same as those of the above embodiment and will not be described in detail.

[0052] Embodiment 6: This embodiment is further expanded on the basis of the above embodiment. Figure 7 As shown, a wing seat 114 is installed on the flight motor 112 , and a connecting end is provided on the wing 102 , and the connecting end is rotatably connected to the wing seat 114 .

[0053] The shape of the connecting end of the wing 102 is as follows: Figure 7 As shown, when the flight motor 112 drives the wing seat 114 to rotate, the two wings 102 are in opposite directions. When the flight motor 112 stops rotating, one of the wings 102 can be manually moved so that the two wings 102 are in the same direction, so as to be stored and reduce the volume.

[0054] The other parts of this embodiment are the same as those of the above embodiment and will not be described in detail.

[0055] Embodiment 7: This embodiment is further expanded on the basis of the above embodiment. Figure 1-Figure 4 As shown, the support leg 103 is rotatably connected to the water tank 105 , the support leg 103 has an elastic telescopic function, and a protective plate 104 is provided at the end of the support leg 103 .

[0056] When the drone 1 takes off, the support leg 103 is no longer pressed down by the drone 1 and begins to recover its length. At this time, the support leg 103 can be manually rotated 90 degrees. Figure 1 In the state shown, the protective plate 104 can surround and protect the wing 102; prevent the wing 102 from hitting the tower or wires due to excessive movement caused by operational errors during the cleaning process; after the cleaning is completed, the support foot 103 is pushed back to its original position, and the support foot 103 is compressed and shortened after contacting the ground, and provides a buffer, and finally the support foot 103 supports the drone 1.

[0057] The other parts of this embodiment are the same as those of the above embodiment and will not be described in detail.

[0058] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Any simple modification or equivalent change made to the above embodiment based on the technical essence of the present invention shall fall within the protection scope of the present invention.
