Description

Technical Field

[0001] The invention belongs to the technical field of power transmission lines, and in particular relates to a foreign matter cleaning device for overhead power transmission lines. Background Art

[0002] Overhead transmission lines are transmission lines that use insulators to fix transmission wires on towers erected on the ground to transmit electric energy. Compared with underground transmission lines, overhead transmission lines do not require large-scale underground excavation and pipeline laying, and have lower construction costs. During the operation of transmission lines, they are polluted by industrial pollution, dust, sea salt particles (in coastal areas), etc. These pollutants adhere to the surface of the insulator. When encountering humid weather such as fog, drizzle, and snowmelt, the surface dirt layer of the insulator will be wetted, causing the insulation performance of the insulator to drop sharply. In this case, dirty flashover may occur. Cleaning the surface of the wire can remove impurities such as dirt, optimize the conductive performance of the wire, and thus reduce the loss of electric energy during transmission. This is of great significance for achieving efficient power transmission and reducing energy costs.

[0003] Currently, most of the cleaning of foreign objects on transmission lines is done manually. During the cleaning process, workers need to take protective safety measures and move along the direction of the transmission line to clean. Although manual cleaning is very effective, it also leads to low cleaning efficiency and a high risk factor. Summary of the invention

[0006] Through the above technical solution, the fixed cylinder cleaning assembly and the limited rotation mechanism enable the fixed cylinder cleaning assembly to achieve rotational cleaning. When the brush plate and the wet sponge plate are worn or damaged, they can be quickly removed from the first mounting cylinder and the second mounting cylinder and replaced, thereby improving the overall cleaning efficiency of the device.

[0007] Furthermore, the limited rotation mechanism includes a connecting seat fixedly installed between the second mounting frame, an adjusting threaded rod is rotatably connected between the connecting seats, a first motor is fixedly installed on one side of the connecting seat, an output end of the first motor is fixedly connected to the adjusting threaded rod, two connecting blocks are threadedly connected on the adjusting threaded rod, and the threads on both sides of the adjusting threaded rod are in opposite directions, and the lower ends of the two connecting blocks are respectively fixedly connected with fixing rings, and limited blocks are fixedly connected on both sides of the fixing ring.

[0008] Through the above technical solution, the output end of the first motor drives the adjusting threaded rod to rotate.

[0011] Furthermore, support seats are symmetrically installed on both sides of the second mounting frame, and a guide rod is fixedly connected between the support seats on the same side, and the guide rod is slidably connected to the limit block.

[0012] Through the above technical solution, when the fixed ring moves, the limit blocks on both sides of the fixed ring can move along the direction of the guide rod, so that the movement of the fixed rings on both sides is more stable, and the guide rod can prevent the fixed ring from being disturbed by lateral force and deviating.

[0037] like Figure 1-Figure 7As shown, the fixed barrel cleaning assembly 2 includes a first mounting barrel 21 and a second mounting barrel 22, the first mounting barrel 21 and the second mounting barrel 22 are rotatably connected, the first mounting barrel 21 and the second mounting barrel 22 are respectively fixedly connected to the outside with a fixing frame 23, and a plurality of positioning columns 24 are fixedly installed on the fixing frame 23, and the positioning columns 24 on the outside of the first mounting barrel 21 and the second mounting barrel 22 are aligned with the positioning groove 48, so that the fixed barrel cleaning assembly 2 can be fixed while the internal cleaning assembly 3 can also rotate to clean the surface of the power transmission line; the cleaning assembly 3 includes the first mounting barrel 21 and the second mounting barrel 22. A fixedly installed magnetic base 31 has a first magnetic pole block 32 fixedly installed on the magnetic base 31, a second magnetic pole block 33 is arranged on the first magnetic pole block 32, a brush plate 34 is fixedly installed on the second magnetic pole block 33 on one side, and a wet sponge board 35 is fixedly installed on the second magnetic pole block 33 on the other side. Different cleaning components 3 are installed according to the line diameter of the transmission line to ensure that the brushes inside the brush plate 34 and the wet sponge board 35 can closely adhere to the surface of the transmission line. When the cleaning component 3 needs to be replaced, the second magnetic pole block 33 connected to the lower ends of the brush plate 34 and the wet sponge board 35 is directly removed from the first magnetic pole block 32.

[0038] like Figure 1-Figure 8 As shown, the fixing assembly 5 includes an upper fixing seat 51 fixedly connected to the second mounting frame 11, a lower fixing seat 52 is arranged at the lower side of the upper fixing seat 51, and the lower fixing seat 52 is fixedly connected to one side of the first mounting frame 1, and positioning holes 53 are provided on the upper fixing seat 51 and the lower fixing seat 52, and a bolt head 54 is arranged on the upper fixing seat 51, and a long bolt 55 is fixedly connected to the lower end of the bolt head 54, and a locking nut 56 is threadedly connected to the lower end of the long bolt 55.

[0039] like Figure 1-Figure 9As shown, the device driving mechanism 6 includes a driving support frame 61 fixedly installed between the first mounting frame 1, and a mounting shell 62 is symmetrically fixedly installed on the driving support frame 61. A fixing column 63 is rotatably connected in the mounting shell 62 on one side, and a bidirectional threaded rod 64 is rotatably connected in the mounting shell 62 on the other side. One end of the bidirectional threaded rod 64 is fixedly connected to the output end of the third motor 65, and the third motor 65 is fixedly connected to the upper end of the mounting shell 62. Two moving seats 66 are symmetrically arranged on the bidirectional threaded rod 64 and the mounting shell 62, respectively. The moving seat 66 on one side is threadedly connected to the bidirectional threaded rod 64, and the moving seat 66 on the other side is slidably connected to the fixing column 63, and the corresponding moving seats 66 are rotatably connected to each other. The two-way threaded rod 64 is dynamically connected with a connecting shaft 67, and a motor driving wheel 68 is fixedly installed in the middle of the connecting shaft 67. The threads on both sides of the two-way threaded rod 64 are in opposite directions. The third motor 65 drives the two-way threaded rod 64 to rotate. Since the threads on both sides of the two-way threaded rod 64 are in opposite directions, the two moving seats 66 on the two-way threaded rod 64 simultaneously drive the connecting shaft 67 and the motor driving wheel 68 to slide toward the central power transmission line until the motor driving wheels 68 on both sides are close to the power transmission line, and the power supply of the motor driving wheel 68 is started. The motor driving wheel 68 drives the device to roll in the direction of the power transmission line, so that the cleaning component 3 can rotate and clean the power transmission line while moving in the direction of the power transmission line.

[0040] The working principle of this embodiment is as follows: when the power transmission line needs to be cleaned, different cleaning components 3 are installed according to the line diameter of the power transmission line to ensure that the brushes inside the bristle plate 34 and the wet sponge plate 35 can be in close contact with the surface of the power transmission line. When the cleaning component 3 needs to be replaced, the second magnetic pole block 33 connected to the lower end of the bristle plate 34 and the wet sponge plate 35 can be directly removed from the first magnetic pole block 32;

[0041] The fixed cylinder cleaning assembly 2 is turned to open, and the power transmission line is placed in the middle of the fixed cylinder cleaning assembly 2. The fixed cylinder cleaning assembly 2 is closed. Further, the first mounting frame 1 and the second mounting frame 11 are turned together, and the long bolt 55 is aligned with the positioning hole 53 and inserted. At the same time, the locking nut 56 is aligned with the lower end of the long bolt 55 and spirally rotated to fix it. The locking and fixing between the first mounting frame 1 and the second mounting frame 11 is completed, and the fixed cylinder cleaning assembly 2 is placed on the fixed base 15, and the positioning column 24 outside the first mounting cylinder 21 and the second mounting cylinder 22 is aligned with the positioning groove 48, and the first motor 42 is started. The output end of the first motor 42 is driven by the first motor 42. The threaded rod 41 is adjusted to rotate. Since the threads on both sides of the threaded rod 41 are in opposite directions, the connecting blocks 43 on both sides simultaneously drive the fixing ring 44 and the limiting ring 47 to slide toward the fixing barrel cleaning assembly 2, and the positioning column 24 can be engaged in the positioning groove 48. The power supply of the second motor 411 is started, and the output end of the second motor 411 drives the gear 412 to rotate. The gear 412 can transmit power to the gear ring 410 through meshing. The gear ring 410 can drive the limiting ring 47 and the fixing barrel cleaning assembly 2 to rotate through the connecting frame 49, thereby causing the cleaning assembly 3 in the fixing barrel cleaning assembly 2 to rotate to clean the surface of the power transmission line.

[0042] Start the third motor 65, and the third motor 65 drives the bidirectional threaded rod 64 to rotate. Since the threads on both sides of the bidirectional threaded rod 64 are in opposite directions, the two moving seats 66 on the bidirectional threaded rod 64 simultaneously drive the connecting shaft 67 and the motor drive wheel 68 to slide toward the central power transmission line until the motor drive wheels 68 on both sides are close to the power transmission line. Start the power supply of the motor drive wheel 68, and the motor drive wheel 68 drives the device to roll in the direction of the power transmission line, so that the cleaning component 3 can rotate and clean the power transmission line while moving in the direction of the power transmission line.
