Description

Technical Field

[0001] The invention belongs to the technical field related to insulator contamination monitoring, and in particular relates to a non-contact insulator contamination monitoring device. Background Art

[0002] The contamination flashover of insulators seriously affects the safe operation of the power supply system. In fog, dew, drizzle or acid wet precipitation, the flashover voltage of the insulator surface drops greatly after the contamination absorbs water, resulting in the occurrence of contamination flashover accidents. Therefore, it is very necessary to understand the degree of contamination on the surface of insulators in a timely, simple and large-scale manner, formulate targeted and accurate cleaning cycle strategies, and realize fast, non-destructive and non-contact insulator contamination live monitoring.

[0003] After searching, the patent publication number is CN118942813A, which discloses a Chinese patent of a high-strength combined electric porcelain insulator and a method thereof. By setting a locking component, a front connector and a rear connector, when the front connector and the rear connector are installed with the two ends of the installation column, the locking component can be controlled to work synchronously. When the locking component is working, the first trapezoidal block and the second trapezoidal block can be controlled to move along the window and to interfere with and limit the two sides of the insulating porcelain plate. Compared with the traditional installation method of the insulating porcelain plate, the device can stably fix the insulating porcelain plate, and can also use the bird-repelling monitoring component, which can not only prevent birds from building in the sky, but also prevent birds from building in the sky. The nest can also monitor the status of the insulator, which is convenient for maintenance personnel to promptly inspect the insulator when the insulator is broken; however, there are some shortcomings when the above device is actually used. The shape of the insulator is round. When it is currently monitored for contamination, it is often monitored by infrared or ultraviolet monitoring methods. However, due to the special shape of the insulator, it is necessary to move the monitoring position multiple times for all-round contamination monitoring. Otherwise, the monitoring results are not accurate enough. This monitoring method has high requirements on time cost. Based on this, a non-contact insulator contamination monitoring device is proposed that can solve the above problems. Summary of the invention

The terms "first", "second", etc. in the specification and claims of this application or the above drawings are used to distinguish different objects, rather than to describe a specific order.

[0031] Reference to "embodiment" herein means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of this application. The phrase does not necessarily refer to the same embodiment at each occurrence in the specification, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0032] An embodiment of the present invention provides a non-contact insulator pollution monitoring device, as Figures 1 - 10As shown in the figure, it includes a laser monitoring head 1, which is connected to a moving unit. The moving unit is used to drive the laser monitoring head 1 to move in the axial direction of the insulator body 2. The moving unit is connected to a rotating unit, and the rotating unit is used to drive the laser monitoring head 1 to rotate in the circumferential direction of the insulator body 2. An angle adjustment unit for finely adjusting the angle of the laser monitoring head 1 is provided on the moving unit.

[0033] When the above device is actually used, the moving unit drives the laser monitoring head 1 to move in the axial direction of the insulator body 2. At the same time, the rotating unit also drives the laser monitoring head 1 to perform a circular motion, enabling the monitoring of various positions of the insulator body 2. Driven by the moving unit, it can cooperate with the angle adjustment unit to drive the laser monitoring head 1 to adjust the angle on the basis of linear motion and circular motion, thereby enabling the all-round monitoring of the dirt on the insulator body 2.

[0034] The insulator body 2 is sleeved outside the cable body 20. First through grooves 21 for the cable body 20 to pass through are provided on both the first side plate 3 and the second side plate 8. A contact unit for contacting the cable body 20 is provided in the first through groove 21.

[0035] Combined Figure 5 As shown, the contact unit includes second clamping grooves 22 opened in the first side plate 3 and the second side plate 8. A first clamping plate 23 is clamped in the second clamping grooves 22. The side surface of the first clamping plate 23 is connected to the side wall of the second clamping groove 22 through a first spring 24 for providing elastic force. A third connecting rod 25 extending out of the second clamping groove 22 is fixedly connected to the side surface of the first clamping plate 23. A contact curved plate 26 is fixedly connected to the end of the third connecting rod 25.

[0036] A plurality of fourth connecting rods 44 arranged in an array for connecting with an external unmanned aerial vehicle are fixedly connected to the upper end of the second connecting rod 9.

[0037] When the above contact unit is actually used, an external unmanned aerial vehicle lifts the entire device through the fourth connecting rod 44 and places it at the position of the insulator body 2 for monitoring. When placing, the contact curved plate 26 contacts the side surface of the cable body 20, and under the action of the first spring 24, it can stably contact cable bodies 20 with different diameters. And when monitoring, the unmanned aerial vehicle is in a hovering state.

[0038] The mobile unit includes two first side plates 3 symmetrically arranged. The two first side plates 3 are connected by a first connecting rod 4. A mobile motor 5 is fixedly connected to the side of the first side plate 3. The output end of the mobile motor 5 is fixedly connected to a reciprocating lead screw 6. The end of the reciprocating lead screw 6 is rotatably connected to the first side plate 3. A reciprocating slider 7 is sleeved outside the reciprocating lead screw 6. The first connecting rod 4 passes through the reciprocating slider 7. The lower end of the reciprocating slider 7 is connected to the laser monitoring head 1 through an angle adjustment unit.

[0039] When the above-mentioned mobile unit is actually used, the rotation of the mobile motor 5 drives the rotation of the reciprocating lead screw 6, which in turn drives the reciprocating slider 7 to move in a straight line direction. The reciprocating slider 7 can drive the laser monitoring head 1 to move reciprocally to monitor the contamination of the insulator body 2.

[0040] Combined with Figure 3 and Figure 10 The rotating unit includes two second side plates 8 symmetrically arranged. The two second side plates 8 are connected by a plurality of second connecting rods 9. A rotating motor 11 is fixedly connected to the side of one of the second side plates 8 through a third connecting plate 10. The output end of the rotating motor 11 is fixedly connected to a guide shaft 12. A plurality of symmetrically arranged guide shafts 12 are rotatably connected to the side of the second side plate 8. A conveyor belt 13 for transmission is arranged in cooperation with the outside of the plurality of guide shafts 12. The two outer guide shafts 12 are fixedly connected to a rotating gear 14. A first set of teeth 15 is arranged on the side of the rotating gear 14. A guide ring body 16 is fixedly connected to the second side plate 8. The guide ring body 16 is in an open shape. A rotating ring body 17 is sleeved outside the guide ring body 16. Both the guide ring body 16 and the rotating ring body 17 are in an open-shaped structure, which can facilitate the contact of the entire device with the cable body 20. The rotating ring body 17 is fixedly connected to the first side plate 3. A first clamping groove 18 that cooperates with the guide ring body 16 is arranged on the rotating ring body 17. Due to the symmetric arrangement of the rotating gears 14, when the rotating ring body 17 rotates to drive the laser monitoring head 1 to rotate, it is ensured that when one rotating gear 14 disengages from the second set of teeth 19, the other side can always drive the whole to rotate, ensuring the stability of the rotation of the entire device. A second set of teeth 19 that meshes with the first set of teeth 15 is arranged on the side of the rotating ring body 17.

[0041] When the above-mentioned rotating unit is actually used, the rotating motor 11 rotates to drive the guide shaft 12 to rotate, drives the conveyor belt 13 to rotate periodically, and then can drive the rotating gear 14 to rotate. The engagement of the first gear teeth 15 and the second gear teeth 19 can drive the rotating ring body 17 to rotate around the guide ring body 16. The rotating ring body 17 can drive the second side plate 8 to rotate, and then drive the laser monitoring head 1 to rotate, so as to perform all-round pollution monitoring on the insulator body 2.

[0042] Combined with Figure 6 , Figure 7 , Figure 8 and Figure 9 , the angle adjustment unit includes two symmetrically arranged first connecting plates 27 fixedly connected to the lower end of the reciprocating slider 7. The two first connecting plates 27 are fitted with a first rotating cylinder 28. The first rotating cylinder 28 is connected to the laser monitoring head 1. A second rotating cylinder 29 is arranged on the outer side of the first rotating cylinder 28. The first rotating cylinder 28 and the second rotating cylinder 29 are connected by a rotation limiting unit. A plurality of first push plates 30 distributed in a circumferential array are fixedly connected to the side surface of the second rotating cylinder 29. A second push plate 31 cooperating with the first push plate 30 is fixedly connected to the first side plate 3.

[0043] An annular clamping protrusion 32 is fixedly connected to the side surface of the second rotating cylinder 29, and an annular clamping groove 33 cooperating with the annular clamping protrusion 32 is formed on the first connecting plate 27.

[0044] When the reciprocating slider 7 moves reciprocally, whenever the first push plate 30 arranged on the second rotating cylinder 29 moves to the position where it contacts the second push plate 31, it will drive the first rotating cylinder 28 to rotate by a certain angle under the drive of the rotation limiting unit. Then, with the combined action of the moving unit and the rotating unit and the fine adjustment of the angle, the pollution monitoring of the insulator body 2 is more comprehensive.

[0045] The laser monitoring head 1 is fixedly connected to the laser monitoring main body 45. A first connecting block 34 is fixedly connected to the upper end of the laser monitoring main body 45. A second connecting plate 35 is fixedly connected to the side surface of the first connecting block 34. A second connecting block 36 whose inner diameter size fits the inner diameter of the first rotating cylinder 28 is fixedly connected to the side surface of the second connecting plate 35. A plurality of first clamping blocks 37 distributed in a circumferential array are fixedly connected to the inner wall of the first rotating cylinder 28. A circumferential array of third clamping grooves 38 cooperating with the first clamping blocks 37 is formed on the second connecting block 36. The second connecting plate 35 is magnetically connected to the first rotating cylinder 28.

[0046] The initial position of the laser monitoring head 1 can be adjusted according to requirements. Specifically, the first clamping block 37 is inserted into the third clamping groove 38, and the second connecting plate 35 is magnetically connected to the first rotating cylinder 28 to ensure the stability of the connection. The angle of the laser monitoring head 1 in the initial position is defined.

[0047] The rotation limiting unit includes a plurality of fourth connecting plates 39 fixedly connected to the outer side of the first rotating cylinder 28 and distributed in a circumferential array. The side surface of the fourth connecting plate 39 is rotatably connected to the first limiting plate 41 through a first rotating shaft 40. A torsion spring 42 is sleeved on the outer side of the first rotating shaft 40. A plurality of second limiting plates 43 distributed in a circumferential array are fixedly connected to the inner wall of the second rotating cylinder 29. The first limiting plate 41 and the second limiting plate 43 face in opposite directions.

[0048] When the rotation limiting unit is actually used, when the first push plate 30 and the second push plate 31 are in contact, the first push plate 30 drives the second rotating cylinder 29 to rotate. The first limiting plate 41 does not rotate under the action of the torsion spring 42. Under the action of the first limiting plate 41 and the second limiting plate 43, the first rotating cylinder 28 can be driven to rotate, and then the laser monitoring head 1 is driven to rotate by a certain angle. When the first push plate 30 and the second push plate 31 are separated, the first limiting plate 41 rotates around the first rotating shaft 40. The rotation of the second limiting plate 43 does not drive the first limiting plate 41 to rotate, and thus does not drive the laser monitoring head 1 to rotate in angle. The angle adjustment can be carried out again only after the reciprocating slider 7 moves to the next cycle.

[0049] In summary, the working principle of the present invention is as follows: The moving motor 5 rotates to drive the reciprocating lead screw 6 to rotate, and then drives the reciprocating slider 7 to move in a straight line direction. The reciprocating slider 7 can drive the laser monitoring head 1 to move reciprocally to monitor the contamination of the insulator body 2; the rotating motor 11 rotates to drive the guide shaft 12 to rotate, drives the conveyor belt 13 to rotate periodically, and then can drive the rotating gear 14 to rotate. The meshing of the first tooth row 15 and the second tooth row 19 can drive the rotating ring body 17 to rotate around the guide ring body 16. The rotating ring body 17 can drive the second side plate 8 to rotate, and then drive the laser monitoring head 1 to rotate to perform all-round contamination monitoring on the insulator body 2; when the reciprocating slider 7 moves reciprocally, whenever the first push plate 30 provided on the second rotating cylinder 29 moves to the position in contact with the second push plate 31, it will drive the first rotating cylinder 28 to rotate by a certain amount of angle under the drive of the rotation limiting unit. Then, with the cooperation of the moving unit and the rotating unit and the addition of angle fine-tuning, the contamination monitoring of the insulator body 2 is more comprehensive.

[0050] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
