Description

Technical Field

[0002] With the rapid development of economic construction and the gradual improvement of people's living standards, the electricity demand for urban infrastructure has gradually increased. To meet the electricity demand of the whole society, the number of power grid infrastructure projects in China has increased significantly in recent years. When the high-voltage transmission line is out of service for maintenance, it is necessary to inspect the inner wire cores of each transmission line. At present, the wire cores are detected by flaw detection. During maintenance, operators need to climb the poles and towers to perform various tasks such as flaw detection on the high-voltage transmission lines in the high-altitude environment. This method has low safety and is prone to safety hazards of falling from a height. At the same time, when constructing power grid infrastructure projects, in order to avoid electric leakage in the power transmission lines, workers will install insulators between the transmission lines and tower equipment. After long-term use, the dust attached to the insulators will cause the insulation performance of the insulators to decline. Therefore, during operation and maintenance, workers need to clean the insulators to eliminate the safety hazards of the power grid. However, cleaning the insulators manually has low cleaning efficiency, is time-consuming and laborious, and also has the safety hazard of falling from a height. Summary of the Invention

[0026] In addition, in the present invention, descriptions such as "first", "second", etc. are for descriptive purposes only, and do not particularly refer to the meaning of order or sequence, nor are they used to limit the present invention. They are merely used to distinguish components or operations described with the same technical terms, and should not be construed as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, features defined with "first", "second" may explicitly or implicitly include at least one such feature. In addition, the technical solutions and technical features between various embodiments can be combined with each other, but it must be based on the ability of those of ordinary skill in the art to implement. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0027] The present invention provides the following embodiments:

[0028] Embodiment 1: The embodiment of the present invention provides a power grid operation and maintenance inspection system, as Figures 1 - 5 shown, which includes a substrate 1. Wheels 2 are respectively provided at the lower end corners of the substrate 1. A working plate 3 is correspondingly provided at the upper end of the substrate 1. A first support shaft 9 is connected to the front side of the working plate 3. First support blocks 8 are symmetrically provided on the left and right sides of the first support shaft 9. The first support blocks 8 are fixedly connected to the upper end of the substrate 1. A second support shaft 7 is connected to the rear side of the working plate 3. Second support blocks 6 are symmetrically provided on the left and right sides of the second support shaft 7. The second support blocks 6 on the left and right sides are respectively and correspondingly connected to the first telescopic cylinders 4 on the left and right sides. The first telescopic cylinders 4 on the left and right sides are fixedly connected to the third support blocks 5 on the left and right sides. A third support shaft is fixedly provided between the third support blocks 5 on the left and right sides. The third support shaft is rotatably connected to the substrate 1. An inspection table is provided at the upper end of the working plate 3. A protection detection mechanism and a protection rod 25 are installed on the inspection table. The protection detection mechanism is correspondingly arranged with the cleaning mechanism. The cleaning mechanism is installed on the substrate 1.

[0029] The working principle of the above technical solution is:

[0030] The setting of the wheel 2 facilitates the movement of the substrate 1 and the structures mounted thereon. The telescopic cylinders 4 on the left and right sides synchronously expand and contract. When the telescopic cylinders 4 expand and contract, they can drive the working plate 3 to rotate around the support shaft 9, thereby adjusting the angle of the working plate 3 and the structures mounted thereon. The setting of the maintenance platform is used to provide a working space for maintenance personnel. The guardrails 25 on the maintenance platform can protect the maintenance personnel and prevent them from falling from a height, facilitating the maintenance personnel to manually maintain the transmission lines in the power grid. By installing a protection detection mechanism on the maintenance platform, it further protects the maintenance personnel on the platform, solving the technical problem that during maintenance, operators need to climb the pole tower to perform various tasks such as detecting the flaws of high-voltage transmission lines in a high-altitude environment. This method has low safety and is prone to safety hazards such as falling from a height. The protection detection mechanism can also detect the flaws of the inner core of the transmission line. After detecting damage to the inner core of the transmission line, the maintenance personnel can promptly repair the damaged area. The coordinated work of the cleaning mechanism and the protection detection mechanism can automatically clean the insulators without manual cleaning, saving time and effort and avoiding the risk of falling from a height during manual cleaning, solving the technical problems of low cleaning efficiency, time-consuming and laborious manual cleaning of insulators, and also having the safety hazard of falling from a height.

[0031] Embodiment 2: On the basis of Embodiment 1, as Figures 1 - 5 shown, the maintenance platform includes a guide block 10 at the upper end of the working plate 3. The upper end of the guide block 10 is provided with a guide convex groove 11. The guide convex groove 11 is slidably connected to a guide slider 34. A guide rod 12 is rotatably provided in the guide convex groove 11. A spiral groove 44 is provided on the guide rod 12. The spiral groove 44 is slidably connected to a guide ball. The guide ball is rotatably arranged in the through hole of the guide slider 34. The through hole of the guide slider 34 cooperates with the guide rod 12. The guide rod 12 passes through the front end of the guide convex groove 11 and is fixedly connected to an external convex block 16;

[0032] Symmetrically arranged fixing blocks 61 are provided at the left and right ends of the guide slider 34. The fixing blocks 61 on the left and right sides are respectively connected to the base blocks 17 on the left and right sides in a one-to-one correspondence. The base blocks 17 on the left and right sides are respectively arranged on the left and right sides of the upper end of the working plate 3, and the base blocks 17 are slidably connected to the working plate 3. A sliding groove is provided at the upper end of the base block 17. The sliding groove is slidably connected to a movable block 18. A telescopic cylinder 2 is fixedly provided between the sliding groove and the movable block 18. An inspection plate 39 is fixedly provided between the movable blocks 18 distributed left and right.

[0033] The working principle of the above technical solution is as follows:

[0034] The provision of the guiding convex groove 11 guides the sliding of the guiding slider 34. When the guiding slider 34 slides, it drives the guiding ball and the fixed block 61 to move. The guiding ball slides along the spiral groove 44, thereby driving the guiding rod 12 to rotate. The guiding rod 12 drives the external convex block 16 to rotate. When the fixed block 61 moves, it drives the base block 17 to slide along the upper end of the working plate 3. When the second telescopic cylinder in the base block 17 expands and contracts, it can drive the movable block 18 to slide along the sliding groove, and the movable block 18 drives the inspection plate 39 to move up and down. The upper end of the inspection plate 39 serves as the working space for the maintenance personnel, which can change the height of the maintenance personnel and facilitate the maintenance personnel to perform maintenance work on transmission lines at different heights.

[0035] Embodiment 3: On the basis of Embodiment 2, as Figures 1 - 5 shown, the upper end of the left movable block 18 is rotatably connected to the second rotating disk 15. Protective rods 25 are respectively provided on the front and rear sides of the second rotating disk 15. The protective rods 25 are fixedly connected to the first rotating disk 19. The first rotating disk 19 is rotatably connected to the upper end of the right movable block 18. The front protective rod 25 is a threaded rod, and the rear protective rod 25 is a cylindrical rod. The front protective rod 25 is threadedly connected to the front protective shell 26, and the rear protective rod 25 is slidably connected to the rear protective shell 26. A working shell 30 is fixedly provided between the front and rear protective shells 26. An opening for the protective rod 25 to pass through is provided on the working shell 30;

[0036] The first rotating disk 19 is fixedly connected to the first gear 20. An opening groove 23 is provided at the front end of the right movable block 18. A movable rod 22 is rotatably provided in the opening groove 23. The movable rod 22 is fixedly connected to the third gear 21. The third gear 21 is correspondingly meshed with the first gear 20. The movable rod 22 passes through the side end of the opening groove 23 and is fixedly connected to the external operating block. The first rotating disk 19 is eccentrically connected to the second gear 24. The third gear 21 is correspondingly meshed with the second gear 24. The second gear 24 is fixedly connected to the front protective rod 25.

[0037] The working principle of the above technical solution is:

[0038] When maintenance personnel stand on the maintenance board 39, they need to stand between the protective bars 25 on the front and rear sides. The protective bars 25 can be connected to the protective hooks worn by the maintenance personnel to protect the maintenance personnel and prevent them from falling. By driving the movable rod 22 to move left and right through the operation block, the third gear 21 meshes with the second gear 24. Then, rotate the operation block, and the operation block drives the movable rod 22 to rotate. The movable rod 22 drives the second gear 24 to rotate through the third gear 21. The second gear 24 drives the front protective bar 25 to rotate. When the front protective bar 25 rotates, it drives the front protective shell 26 to move left and right. The front protective shell 26 drives the rear protective shell 26 to move synchronously through the working shell 30, so that the front and rear protective shells 26 move to the corresponding positions of the maintenance personnel to further protect the maintenance personnel. When the direction of the transmission line is inclined along the vertical plane, by driving the movable rod 22 to move through the operation block, the third gear 21 meshes with the first gear 20. By driving the movable rod 22 to rotate through the operation block, the movable rod 22 drives the first gear 20 to rotate through the third gear 21. The first gear 20 drives the first rotating disk 19 to rotate. The first rotating disk 19 drives the second rotating disk 15, the front and rear protective shells 26 and the working shell 30 to rotate through the protective bar 25, which is convenient for adjusting the angle of the protective shell 26 while keeping the maintenance board 39 horizontal. At this time, it is necessary to ensure that the sector gear 14 is not meshed with the rack 13;

[0039] When not operating the operation block, the third gear 21 is meshed with the first gear 20, so that the third gear 21 cannot rotate, and further the first gear 20 cannot rotate, ensuring that the first rotating disk 19 and the corresponding second rotating disk 15 are in a static state. Optionally, a threaded hole can be provided on both the operation block and the right movable block 18. The two threaded holes are connected to the screw rod. When the operation block needs to be operated, the screw rod is unscrewed and separated from the threaded hole on the right side of the movable block 18, so that the operation block can move freely. After the operation block is not operated, the screw rod is connected to the threaded hole on the right side of the movable block 18, ensuring the limiting effect of the third gear 21 on the first gear 20. When rotating the operation block, the rotation angle of the operation block is 360° or a multiple of 360°.

[0040] Example 4: On the basis of Example 3, as Figures 1 - 5As shown in the figure, the protection detection mechanism includes a working cavity 42 provided at the upper end of the working shell 30. A driving motor 41 is fixedly installed at the left end of the working shell 30. The telescopic motor shaft of the driving motor 41 penetrates through the center of the second rotating disk 15 and the left end of the working shell 30 and enters the working cavity 42, and is fixedly connected to a sector bevel gear 43. A rotating shaft 38 is rotatably provided between the front and rear ends of the working cavity 42. Bevel gears 40 are respectively provided on the front and rear sides of the rotating shaft 38. The bevel gears 40 are correspondingly meshed with the sector bevel gear 43. The rotating shaft 38 penetrates through the side end of the working cavity 42 and is fixedly connected to an external fourth gear 28. The fourth gear 28 is meshed with a toothed ring 27. The toothed ring 27 is fixedly connected to a rotating sleeve 29. Through holes one are provided through the front and rear ends of the protective shell 26. The rotating sleeve 29 is rotatably provided in the through holes one of the protective shells 26 on the front and rear sides. A number of flaw detectors or a number of cleaning brushes are circumferentially and evenly arranged in the through hole two of the rotating sleeve 29. Slots are provided at the upper ends of the protective shell 26 and the rotating sleeve 29. The slots are communicated with the through hole two;

[0041] The telescopic motor shaft of the driving motor 41 is fixedly connected to a first pulley 31. The first pulley 31 is connected to a second pulley 33 through a conveyor belt 32. The second pulley 33 is fixedly connected to a sector gear 14 through a connecting shaft. The connecting shaft is rotatably connected to the left base block 17. The sector gear 14 is correspondingly meshed with a rack 13. The rack 13 is fixedly arranged on the upper left side of the working plate 3. The conveyor belt 32 is in contact with a tension pulley 35. The tension pulley 35 is rotatably connected to a mounting seat 36. The mounting seat 36 is fixedly connected to a first fixing plate 60 through a number of first springs 37. The first fixing plate 60 is fixedly connected to the left base block 17. The mounting seat 36 is slidably connected to the left base block 17.

[0042] The working principle of the above technical solution is as follows:

[0043] A slot is provided for the power transmission line to pass through and enter the through hole II. The maintenance personnel keep a certain distance from the outside of the rotating sleeve 29 to avoid accidental contact between the maintenance personnel and the power transmission line, thus preventing safety accidents. When maintaining the power transmission line, the fixed section of the telescopic motor shaft is fixedly connected to the first pulley 31. The fixed section of the telescopic motor shaft is rotatably connected to the center of the second rotating disc 15. The movable section of the telescopic motor shaft is rotatably connected to the left end of the working shell 30. Thus, when the working shell 30 moves, it can drive the telescopic motor shaft to freely expand and contract, and the rotation of the telescopic motor shaft will not drive the second rotating disc 15 to rotate. Control the driving motor 41 to work. The motor shaft of the driving motor 41 drives the first pulley 31 and the sector bevel gear 43 to rotate. The first pulley 31 drives the second pulley 33 to rotate through the conveyor belt 32. Due to the setting of the tension pulley 35, when the first pulley 31 moves up and down with the movable block 18, the conveyor belt 32 drives the tension pulley 35 to move. The tension pulley 35 drives the first spring 37 to deform through the mounting seat 36, so that the conveyor belt 32 always remains in a tensioned state. Thus, the first pulley 31 always drives the second pulley 33 to rotate through the conveyor belt 32. The second pulley 33 drives the sector gear 14 to rotate through the connecting shaft. When the toothed section of the sector gear 14 meshes with the rack 13, since the rack 13 is fixedly installed on the working plate 3, the sector gear 14 rolls in the front-back direction. Thus, it drives the left base block 17 to slide along the upper end of the working plate 3 through the connecting shaft. The left base block 17 drives the left and right fixed blocks 61, the guide sliders 34 and the right base block 17 to move synchronously. The left and right base blocks 17 drive the left and right movable blocks 18 to move synchronously. The movable blocks 18 drive the front and rear protective shells 26 to move synchronously. The protective shells 26 drive the rotating sleeve 29 to move. After the toothed section of the sector gear 14 disengages from the rack 13, the left base block 17 stops moving, making the protective shell 26 stationary. At this time, the sector bevel gear 43 starts to mesh with the bevel gear 40. Specifically, when the sector bevel gear 43 meshes with the front bevel gear 40, the sector bevel gear 43 is not in a meshing state with the rear bevel gear 40. At this time, the sector bevel gear 43 drives the front bevel gear 40 to rotate a certain angle. The front bevel gear 40 drives the rotating shaft 38 to rotate a certain angle. The rotating shaft 38 drives the fourth gear 28 to rotate a certain angle. The fourth gear 28 drives the toothed ring 27 to rotate a certain angle. After the sector bevel gear 43 disengages from the front bevel gear 40, when the sector bevel gear 43 meshes with the rear bevel gear 40 and drives the rear bevel gear 40 to rotate, the rear bevel gear 40 drives the rotating shaft 38 to rotate in the reverse direction by a certain angle. The rotating shaft 38 drives the toothed ring 27 to rotate in the reverse direction by a certain angle through the fourth gear 28. The purpose of driving the toothed ring 27 to rotate reciprocally is achieved, and the protective shell 26 remains stationary during the reciprocal rotation of the toothed ring 27. The toothed ring 27 drives the rotating sleeve 29 to rotate reciprocally. The rotating sleeve 29 drives the flaw detector to rotate reciprocally. Thus, the flaw detector can perform a full-range detection on the periphery of the power transmission line, improving the detection effect on the inner wire core of the power transmission line.The flaw detector is connected to the alarm through a controller. After the flaw detector detects damage to the inner core of the power transmission line, the controller controls the alarm to sound an alarm, reminding the maintenance personnel to repair the corresponding part of the power transmission line where the flaw detector is located at this time. The flaw detector refers to CN202210753680 - A high-voltage power transmission line operation and maintenance equipment. When the sector bevel gear 43 and the bevel gears 40 on both the front and back sides are not engaged, the serrated section of the sector gear 14 is in engagement with the rack 13, enabling the reciprocating rotation and intermittent movement of the rotating sleeve 29, so as to detect the power transmission line while moving along its length direction. The reciprocating rotation and movement of the rotating sleeve 29 only need to be driven by the driving motor 41, without the need for multiple electrical components to cooperate with each other for driving, which is convenient for the maintenance personnel to operate. When the direction of the power transmission line is inclined along the vertical plane, by controlling the operation block, the inspection plate 39 is kept horizontal while adjusting the angle of the protective shell 26. After the base block 17 moves to the maximum stroke, the driving motor 41 is controlled to work in the reverse direction, so that the base block 17 and its corresponding connected rotating sleeve 29 return to their original positions. Then, the base plate 1 is moved the same distance as the maximum stroke of the base block 17 to continue the inspection of the power transmission line. The moving direction of the base plate 1 is the same as the horizontal direction of the power transmission line.,

[0044] Embodiment 5: On the basis of Embodiment 4, as Figures 1 - 7 shown, the cleaning mechanism includes a storage tank 45. The right end of the storage tank 45 is fixedly connected to a pressure shell 47. The storage tank 45 and the pressure shell 47 are fixedly arranged on the front side of the upper end of the base plate 1. The upper end of the storage tank 45 is provided with a storage chamber. The upper end of the storage chamber is provided with a cover plate one 46. The right end of the storage tank 45 is provided with an outlet. A diversion plate 57 is inclined in the outlet. The left end of the pressure shell 47 is provided with a pressure chamber. The left end of the pressure chamber is communicated with the outlet. The upper end of the pressure chamber is provided with a cover plate two 58. The right end of the pressure chamber is communicated with the inlet of a liquid spraying pipe 49. The liquid spraying pipe 49 is fixedly connected to a mounting block 50. The outlet of the liquid spraying pipe 49 is correspondingly arranged at the rear side of the through hole two. The mounting block 50 is fixedly connected to the rear end of the right movable block 18;

[0045] The cleaning mechanism further includes a push plate 59 slidably arranged in the pressure chamber. The upper end of the push plate 59 is fixedly connected to a push block 48. The push block 48 penetrates through the cover plate two 58 and is fixedly connected to an external connecting plate 53. The connecting plate 53 is fixedly connected to a mating block one 54. The inclined end of the mating block one 54 is slidably connected to the inclined end of a mating block two 55. The mating block two 55 is fixedly connected to a sliding plate 56. The sliding plate 56 is slidably connected to the upper end of the base plate 1. The sliding plate 56 is fixedly connected to a fixing plate two 51 through a spring two 52. The fixing plate two 51 is fixedly arranged on the upper end of the base plate 1. One end of the sliding plate 56 away from the spring two 52 contacts the convex block 16.

[0046] The working principle of the above technical solution is:

[0047] A plug block is provided at the outlet of the liquid spraying pipe 49. When cleaning the insulator, the maintenance personnel do not need to be on the maintenance board 39. At this time, the telescopic cylinder one 4 is controlled to expand and contract to drive the working board 3 to rotate. As the working board 3 rotates, the convex block 16 is always in contact with the sliding board 56. The liquid spraying pipe 49 is a flexible pipe and can move freely. The telescopic cylinder one 4 and the telescopic cylinder two are any one of a pneumatic telescopic cylinder, an electric telescopic cylinder, and a hydraulic telescopic cylinder. Until the length direction of the working board 3 is parallel to the length direction of the insulator, then the movable block 18 is controlled to move, so that the insulator enters the through hole two through the slotted opening. The flaw detection sensor in the through hole two is replaced with a cleaning brush. The driving motor 41 is controlled to work, so that the rotating sleeve 29 rotates and moves intermittently. The cleaning brush cleans the circumferential side of the insulator and gradually moves along the length of the insulator to clean the insulator. And when the guiding slider 34 moves along with the left base block 17, it can drive the external convex block 16 to rotate through the guiding rod 12. When the protruding section of the convex block 16 contacts the sliding board 56, it pushes the sliding board 56 to move, and the spring two 52 is compressed. After the protruding section of the convex block 16 is separated from the sliding board 56, under the elastic action of the spring two 52, the sliding board 56 returns to its original position. The sliding board 56 drives the matching block two 55 to move left and right. The matching block two 55 drives the matching block one 54 to move up and down. The matching block one 54 drives the pushing block 48 to move up and down through the connecting plate 53. The pushing block 48 drives the pushing plate 59 to move up and down. When the pushing plate 59 moves downward, the pushing plate 59 pushes the cleaning liquid in the pressure chamber into the liquid spraying pipe 49, opens the plug block at the outlet of the liquid spraying pipe 49, so that the liquid spraying pipe 49 sprays the cleaning liquid to the rear side of the through hole two, thereby cleaning the insulator. When the pushing plate 59 moves upward, the cleaning liquid stored in the storage tank 45 enters the pressure chamber through the outlet under the action of gravity to supplement the pressure chamber. The setting of the flow guiding plate 57 ensures that the flow direction of the cleaning liquid is from the storage tank 45 to the pressure chamber. And when the rotating sleeve 29 moves, the liquid spraying pipe 49 sprays liquid. When the rotating sleeve 29 rotates, the pressure chamber is supplemented with liquid, and at this time the liquid spraying pipe 49 does not spray liquid. Then the insulator is further brushed by the cleaning brush, which improves the cleaning efficiency of the insulator. And the above cleaning process does not require manual cleaning, which saves time and effort and also avoids potential safety hazards.
