Description

Technical Field

[0001] The utility model relates to the technical field of insulator monitoring, in particular to a monitoring device for dirt on insulators of high-voltage transmission towers. Background Technique

[0002] Insulators of high-voltage transmission towers are important components used to support high-voltage transmission lines. Their main functions are to insulate the power lines during power transmission, prevent current from flowing to the ground through the tower, and support and fix the conductors at the same time. These insulators are usually made of insulating materials such as ceramics, glass fiber reinforced plastics or silicone rubber, etc., to ensure their good insulation performance.

[0003] For the traditional on-line monitoring device for the dirt degree of insulators of high-voltage transmission towers, it is installed on the high-voltage tower for a long time. The through hole of the detection box faces the insulator. After the driving mechanism drives the sliding door to open automatically, the electric telescopic lens inside extends outwards to conduct on-line monitoring of the insulator. However, when the electric telescopic lens in the detection box is opened and extends out of the detection box, due to the limitation of the detection range of the electric telescopic lens, it can only monitor one side of the insulator and cannot achieve large-range monitoring of the insulator, which is inconvenient to use.

[0004] Therefore, the utility model provides a monitoring device for dirt on insulators of high-voltage transmission towers to solve the above problems. Content of the Utility Model

The driving mechanism can drive the detection probe to move, expanding the monitoring range of the detection probe.

The output end of the servo motor passes through the fixed plate and is fixedly connected to the driving gear. One end of the transmission rack away from the driving gear is fixedly connected to the sliding plate. Through the drive of the servo motor, the detection probe can be driven through the cooperation of the transmission rack and the driving gear, and slide in the opposite direction to achieve a wide range of monitoring of the insulator.

Through the opening, the control gear can mesh with the toothed ring, ensuring the normal drive of the toothed ring.

[0015] (III) Beneficial effects

[0016] The monitoring device for the insulator dirt of the high-voltage transmission tower has a simple structure and is convenient to use.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0023] Embodiment 1

[0024] The present invention provides a monitoring device for the insulator dirt of the high-voltage transmission tower. As Figures 1-4 shown, the monitoring device includes a support plate 1, electric push rods 11 symmetrically arranged on the support plate 1, and a fixed plate 2 fixedly installed at the telescopic end of the electric push rods 11;

[0025] On one side of the fixed plate 2 away from the electric push rod 11, sliding plates 21 are symmetrically arranged. On one side of the fixed plate 2 away from the electric push rod 11, sliding grooves 22 are symmetrically arranged. A driving mechanism 23 for driving the sliding plates 21 is arranged in the sliding grooves 22. An annular plate 3 is fixedly installed on the sliding plates 21. One end of the annular plate 3 is provided with a detection probe 4.

[0026] During use, the support plate 1 can be fixed at the installation position of the insulator on the high-voltage transmission tower, and the two annular plates 3 can face the insulator. When monitoring is required, the electric push rod 11 can be turned on to drive the fixed plate 2 and the annular plate 3 to move, so that the two annular plates 3 are located at the outer edge of the insulator. Then, the driving mechanism 23 can be turned on to drive the two annular plates 3 to move in opposite directions, so that the condition of the dirt on the surface of the insulator can be monitored through the detection probe 4. After the monitoring is completed, the electric push rod 11 can be shortened to reset.

[0027] Specifically, the driving mechanism 23 includes a transmission rack 231 slidably installed in the sliding groove 22, a driving gear 232 rotatably installed at one end of the fixed plate 2 away from the electric push rod 11 and meshing with the transmission rack 231, and a servo motor 233 fixedly installed at one end of the fixed plate 2 away from the driving gear 232. The output end of the servo motor 233 passes through the fixed plate 2 and is fixedly connected to the driving gear 232. One end of the transmission rack 231 away from the driving gear 232 is fixedly connected to the sliding plate 21. When the servo motor 233 is turned on, it can drive the driving gear 232 to rotate. The driving gear 232 meshes with the transmission rack 231, and the transmission rack 231 slides in the sliding groove 22. Therefore, when the driving gear 232 rotates, it can drive the two sliding plates 21 to slide in opposite directions, realizing the driving of the sliding plates 21.

[0028] Embodiment 2

[0029] Different from Embodiment 1, a through hole 31 is opened at one end of the annular plate 3. A guiding hole 32 communicating with the through hole 31 is opened on the annular plate 3. A toothed ring 33 is slidably installed in the through hole 31. A control mechanism 34 for driving the toothed ring 33 is arranged on the annular plate 3. A connecting gear 331 adapted to the guiding hole 32 is rotatably installed at one end of the toothed ring 33 close to the sliding plate 21. The detection probe 4 is fixedly connected to the connecting gear 331. A plurality of teeth 321 distributed in an annular array and meshing with the connecting gear 331 are fixedly installed in the guiding hole 32.

[0030] In use, the control mechanism 34 can drive the gear ring 33 to rotate in the through hole 31 within the annular plate 3. The detection probe 4 is rotationally connected to one end of the gear ring 33 through the connecting gear 331. Therefore, when the gear ring 33 rotates, it can drive the detection probe 4 to rotate through the cooperation of the connecting gear 331 and the teeth 321, enabling the detection probe 4 to always face the insulator during movement and achieving large-range monitoring of the insulator.

[0031] Specifically, the control mechanism 34 includes a control motor 341 fixedly installed on the annular plate 3 and a control gear 342 fixedly installed at the output end of the control motor 341 and meshing with the gear ring 33. An opening 35 for the control gear 342 to mesh with the gear ring 33 is formed at one end of the annular plate 3 close to the sliding plate 21. When the control motor 341 rotates, it can drive the control gear 342 to rotate. The control gear 342 passes through the opening 35 and meshes with the gear ring 33, thus enabling the driving of the gear ring 33.

[0032] The above is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and the inventive concept of the present invention, making equivalent replacements or changes, shall be covered by the protection scope of the present invention.
