Description

Technical Field

[0001] The present invention relates to the technical field of electric power maintenance, and in particular to a high-voltage switch detection tool. Background Art

[0002] High-voltage disconnectors are typically located above ground in substations. These disconnectors are connected to hardware via cables, which are fixed to overhead cables to complete the connection between the disconnector and the hardware. Consequently, there's a significant cable tilt between the disconnector and the hardware. Since disconnectors are exposed outdoors year-round, they can experience problems such as loose bolts, corrosion of hardware, and cable cracking. To ensure stable grid operation, staff regularly inspect the disconnectors to prevent unforeseen circumstances.

[0003] In the existing technology, the main maintenance method is non-stop power supply. Inspection personnel need to wear heavy electromagnetic shielding clothing in advance during maintenance, and then establish the same potential between the climbing equipment used and the power line. Only then can the personnel carry out maintenance work on the climbing equipment. This not only creates a dangerous working environment, but also the wearing and taking off of electromagnetic shielding clothing back and forth consumes a lot of physical strength of the personnel.

[0012] The high-voltage switch detection tool proposed by the present invention has the beneficial effect that the high-voltage switch detection tool provided by the present invention can change its shape accordingly according to the environment in which the disconnector is located.

The contact between the outer tire structure and the cable surface is line contact, which greatly increases the contact area between the outer tire structure and the cable, thereby increasing the friction between the outer tire structure and the cable to prevent the outer tire structure from slipping due to the slippery cable surface when working.

DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0030] Example 1

[0031] Reference Figure 1-9 A high-voltage switch inspection tool comprises an arcuate connector 1, on which a camera 33 is mounted. Two connecting rods 2 are fixedly connected to the arcuate connector 1. The connecting rods 2 are connected to a mounting plate 5 via a connecting structure. The connecting structure comprises a connecting plate 3, on which a slide rail 34 is fixedly mounted. A slide groove 31 is fixedly mounted on the connecting rod 2. The slide groove 31 is slidably engaged with the slide rail 34. A fixing bolt 32 is threadedly engaged with the slide groove 31. The fixing bolt 32 is used to lock the slide groove 31 to the slide rail 34.

[0032] like Figure 2-4, multiple rotating shafts 8 are rotatably installed on the connecting plate 3, and the rotating shaft 8 is rotatably connected to the mounting plate 5. A driving rack 9 and two driven racks 13 are slidably matched on the mounting plate 5. The driving rack 9 and the two driven racks 13 are equidistantly distributed on the mounting plate 5. A motor 4 is provided on the connecting plate 3, and a driving gear 6 is fixed to the output end of the motor 4. A driven gear 7 is fixed to the rotating shaft 8. The driving gear 6 matches the driven gear 7. The driving rack 9 and the two driven racks 13 correspond to the rotating shaft 8 one by one, and the driving rack 9 and the two driven racks 13 slide with the rotating shaft 8. An L-shaped connecting ear 801 is rotatably installed on the rotating shaft 8, and a driving bevel gear 24 is fixed to the rotating shaft 8.

[0033] When the motor 4 is working, it drives the driving gear 6 to rotate. The rotation of the driving gear 6 drives the driven gear 7 to rotate. The rotation of the driven gear 7 drives the rotating shaft 8 to rotate. The rotation of the rotating shaft 8 drives the driving bevel gear 24 to rotate.

[0034] like Figure 5-8 The driving rack 9 and the two driven racks 13 are all fixed with an arc-shaped skateboard 17, and the skateboard 17 is slidably matched with the outer tire structure 18. The first gear 10 and the second gear 12 are rotatably mounted on the mounting plate 5. The first gear 10 matches the driving rack 9, and the second gear 12 matches the driven rack 13. The first gear 10 and the second gear 12 are transmitted by a belt 11. The mounting plate 5 is slidably matched with a connecting block 14, which is fixedly connected to the driving rack 9, and a locking bolt 15 is threaded on the connecting block 14.

[0035] When the connecting block 14 slides on the mounting plate 5, it drives the active rack 9 to move. The movement of the active rack 9 drives the first gear 10 to rotate. The rotation of the first gear 10 drives the second gear 12 to rotate through the belt 11. The rotation of the second gear 12 drives the driven rack 13 to move, thereby moving the slides 17 on the active rack 9 and the two driven racks 13 to change the shape of the tire structure 18.

[0036] A first friction wheel 19 is rotatably mounted on the active rack 9, and a first end face gear 20 is fixedly connected to the first friction wheel 19. A first spline shaft 21 is rotatably mounted on the active rack 9, and a first drive wheel 22 is fixedly connected to the first spline shaft 21. The first drive wheel 22 matches the first end face gear 20. A first bevel gear 23 is rotatably mounted on the connecting ear 801 near the active rack 9, and the first bevel gear 23 is slidably fitted on the first spline shaft 21. The first bevel gear 23 matches the active bevel gear 24.

[0037] like Figure 7-11During the rotation process, the active bevel gear 24 will drive the first bevel gear 23 to rotate. The rotation of the first bevel gear 23 will drive the first spline shaft 21 to rotate. The rotation of the first spline shaft 21 will drive the first driving wheel 22 to rotate. The rotation of the first driving wheel 22 will drive the first end face gear 20 to rotate. The rotation of the first end face gear 20 will drive the first friction wheel 19 to rotate. Since the first friction wheel 19 is against the outer tire structure 18, the first friction wheel 19 will drive the outer tire structure 18 to rotate on the skateboard 17 during the rotation process.

[0038] like Figure 7-12 A second friction wheel 29 is rotatably mounted on the driven rack 13, and a second end face gear 30 is fixedly connected to the second friction wheel 29. A second spline shaft 27 is rotatably mounted on the driven rack 13, and a second drive wheel 28 is fixedly connected to the second spline shaft 27. The second drive wheel 28 matches the second end face gear 30. An inner spline tube 25 is rotatably mounted on the connecting ear 801 near the driven rack 13, and a second bevel gear 26 is fixedly connected to the inner spline tube 25. The second bevel gear 26 matches the driving bevel gear 24, and the second spline shaft 27 is slidably fitted in the inner spline tube 25.

[0039] During the rotation of the active bevel gear 24, the second bevel gear 26 is driven to rotate. The rotation of the second bevel gear 26 drives the inner spline tube 25 to rotate. The rotation of the inner spline tube 25 drives the second spline shaft 27 to rotate. The rotation of the second spline shaft 27 drives the second driving wheel 28 to rotate. The rotation of the second driving wheel 28 drives the second end gear 30 to rotate. The rotation of the second end gear 30 drives the second friction wheel 29 to rotate. Since the second friction wheel 29 is against the outer tire structure 18, the second friction wheel 29 will drive the outer tire structure 18 to rotate on the skateboard 17 during the rotation process.

[0040] Workflow:

[0041] When there is no ice on the cable surface: when inspecting the cable of the high-voltage disconnector, the distance between the two tire structures 18 is adjusted by moving the slide groove 31 on the slide rail 34, so that the two tire structures 18 can be clamped on the cable of the disconnector.

[0042] After the two outer tire structures 18 are clamped on the cable, the motor 4 is started. When the motor 4 is working, it drives the driving gear 6 to rotate. The rotation of the driving gear 6 drives the driven gear 7 to rotate. The rotation of the driven gear 7 drives the rotating shaft 8 to rotate. The rotation of the rotating shaft 8 drives the driving bevel gear 24 to rotate.

[0043] in:

[0044] During the rotation process, the active bevel gear 24 will drive the first bevel gear 23 to rotate. The rotation of the first bevel gear 23 will drive the first spline shaft 21 to rotate. The rotation of the first spline shaft 21 will drive the first driving wheel 22 to rotate. The rotation of the first driving wheel 22 will drive the first end face gear 20 to rotate. The rotation of the first end face gear 20 will drive the first friction wheel 19 to rotate. Since the first friction wheel 19 is against the outer tire structure 18, the first friction wheel 19 will drive the outer tire structure 18 to rotate on the skateboard 17 during the rotation process.

[0045] During the rotation of the active bevel gear 24, the second bevel gear 26 is driven to rotate. The rotation of the second bevel gear 26 drives the inner spline tube 25 to rotate. The rotation of the inner spline tube 25 drives the second spline shaft 27 to rotate. The rotation of the second spline shaft 27 drives the second driving wheel 28 to rotate. The rotation of the second driving wheel 28 drives the second end gear 30 to rotate. The rotation of the second end gear 30 drives the second friction wheel 29 to rotate. Since the second friction wheel 29 is against the outer tire structure 18, the second friction wheel 29 will drive the outer tire structure 18 to rotate on the skateboard 17 during the rotation process.

[0046] Based on the above description, it can be seen that the tire structure 18 rotates under the drive of the first friction wheel 19 and the second friction wheel 29, and since the two tire structures 18 are clamped on the cable, the arc-shaped connecting member 1 will be driven to move on the cable during the rotation of the tire structure 18, thereby causing the camera 33 on the arc-shaped connecting member 1 to move on the cable. The camera 33 will capture images of the cable surface during the movement, and the captured images will be wirelessly sent to the terminal. The inspector can inspect the cable surface through the images collected by the terminal.

[0047] When the cable surface is frozen: open the locking bolt 15 and slide the connecting block 14 on the mounting plate 5. The connecting block 14 will drive the active rack 9 to move during the sliding process. Figure 5 and Figure 7 As shown, the connecting block 14 drives the active rack 9 to move downward, and the downward movement of the active rack 9 drives the first gears 10 on both sides to rotate, the first gear 10 drives the second gear 12 to rotate through the belt 11, and the second gear 12 drives the driven rack 13 to move obliquely downward. The oblique downward movement of the two driven racks 13 will increase the distance between the two slides 17, and the outer tire structure 18 between the two slides 17 will become the shape of a crawler track.

[0048] After the outer tire structure 18 is in the shape of a crawler track, the locking bolt 15 is tightened, and the above-mentioned working process when there is no ice on the cable surface is repeated.

[0049] The high-voltage switch detection tool provided by the present invention can change its shape accordingly according to the environment in which the isolating switch is located.

[0050] In a high temperature environment, the outermost insulation layer of the disconnector cable softens in the high temperature environment. During the inspection, the outer tire structure 18 is made circular, and the circular outer tire structure 18 is in point contact with the cable surface to reduce the contact area between the outer tire structure 18 and the cable surface to prevent the heat dissipation performance of the cable from being affected.

[0051] In a rainy and snowy environment, the cable surface of the disconnector becomes slippery due to the influence of rain and snow. During the inspection, the outer tire structure 18 is made into a track shape. The contact mode between the outer tire structure 18 and the cable surface is line contact, which greatly increases the contact area between the outer tire structure 18 and the cable, thereby increasing the friction between the outer tire structure 18 and the cable to prevent the outer tire structure 18 from slipping due to the slippery cable surface when working.

[0052] Example 2

[0053] like Figure 5-6 and Figure 12-13 As shown, the tire structure 18 includes an inner ring 1801 and an outer ring 1805. The inner ring 1801 can be slidably engaged on the slide plate 17, and the outer ring 1805 is sleeved on the inner ring 1801. A plurality of elastic support members 1802 are provided between the inner ring 1801 and the outer ring 1805. A slot 1804 is provided on the outer ring 1805. A plurality of anti-sliding blocks 1803 can be slidably engaged in the slot 1804. The anti-sliding blocks 1803 are fixedly connected to the inner ring 1801, and a pressure block 16 is fixedly connected to the connecting block 14.

[0054] Based on the above description, it can be seen that when the connecting block 14 slides, the shape of the tire structure 18 will change, such as Figure 12 As shown in the figure, the track shape of the outer tire structure 18 is shown. Driven by the connecting block 14, the pressure block 16 passes between the two slides 17 and is squeezed on the inner ring 1801. The inner ring 1801 has elastic deformation ability. After the inner ring 1801 is squeezed by the pressure block 16, the anti-slider 1803 on the inner ring 1801 will pass through the slot 1804, increasing the friction coefficient of the outer ring 1805.

[0055] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
