In order to meet the electricity demand of the whole society, the number of power grid infrastructure projects in my country has been significantly increased in recent years. When the high-voltage transmission line is shut down for maintenance, the internal core of each transmission line must be inspected. At present, the core is inspected by flaw detection. During maintenance, operators need to climb the pole tower to perform flaw detection and other tasks on the high-voltage transmission line in a high-altitude environment. This method has low safety and is prone to safety hazards of falling from heights. At the same time, during the construction of power grid infrastructure projects, in order to avoid leakage in the power transmission line, the staff will install insulators between the transmission line and the tower equipment.

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.

[0021] The working principle of the above technical solution is: The setting of the guide convex groove 11 guides the sliding of the guide slider 34. When the guide slider 34 slides, it drives the guide ball and the fixed block 61 to move. The guide ball slides along the spiral groove 44, thereby driving the guide rod 12 to rotate. The guide 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 telescopic cylinder 2 in the base block 17 is extended and retracted, it can drive the movable block 18 to slide along the sliding groove. 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 of the maintenance personnel. It can change the height of the maintenance personnel, making it convenient for the maintenance personnel to inspect the power transmission lines at different heights.

[0022] Embodiment 3: Based on embodiment 2, Figure 1-Figure 5 As shown, the upper end of the movable block 18 on the left is rotatably connected to the rotating disk 2 15, and the front and rear sides of the rotating disk 2 15 are respectively provided with protective rods 25, the protective rod 25 is fixedly connected to the rotating disk 1 19, and the rotating disk 1 19 is rotatably connected to the upper end of the movable block 18 on the right, 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, and a working shell 30 is fixedly provided between the front and rear protective shells 26, and the working shell 30 is provided with an opening for the protective rod 25 to pass through; The rotating disk 19 is fixedly connected to the gear 1 20, and an opening groove 23 is provided at the front end of the movable block 18 on the right side. A movable rod 22 is rotatably provided in the opening groove 23. The movable rod 22 is fixedly connected to the gear 3 21, and the gear 3 21 is correspondingly meshed with the gear 1 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 rotating disk 19 is eccentrically connected to the gear 2 24, and the gear 3 21 is correspondingly meshed with the gear 2 24. The gear 2 24 is fixedly connected to the protective rod 25 on the front side.

[0023] The working principle of the above technical solution is: When the maintenance personnel stand on the maintenance plate 39, they need to stand between the protection bars 25 on the front and rear sides. The protection bars 25 can be connected to the protection hooks worn by the maintenance personnel to protect the maintenance personnel and prevent them from falling. The movable bar 22 is driven to move left and right by the operating block, so that the gear three 21 is meshed with the gear two 24, and then the operating block is rotated. The operating block drives the movable bar 22 to rotate. The movable bar 22 drives the gear two 24 to rotate through the gear three 21, and the gear two 24 drives the front protection bar 25 to rotate. When the front protection bar 25 rotates, it drives the front protection shell 26 to move left and right. The front protection shell 26 drives the rear protection shell 26 to move synchronously through the working shell 30, so that the front The protective shells 26 on the rear sides are moved to the corresponding positions of the maintenance personnel to further protect the maintenance personnel. If the direction of the transmission line is in an inclined state along the vertical plane, the movable rod 22 is driven to move through the operating block, so that the gear three 21 is engaged with the gear one 20, and the movable rod 22 is driven to rotate through the operating block. The movable rod 22 drives the gear one 20 to rotate through the gear three 21, and the gear one 20 drives the rotating disk one 19 to rotate. The rotating disk one 19 drives the rotating disk two 15, the protective shells 26 and the working shell 30 on the front and rear sides to rotate through the protective rod 25. While the maintenance plate 39 is kept horizontal, the angle of the protective shell 26 can be conveniently adjusted. At this time, it is necessary to ensure that the sector gear 14 is not engaged with the rack 13; When the operating block is not operated, gear three 21 is meshed with gear one 20, so that gear three 21 cannot rotate, and gear one 20 cannot rotate, thereby ensuring that rotating disk one 19 and its corresponding rotating disk two 15 are in a stationary state. Optionally, a threaded hole can be set on the operating block and the movable block 18 on the right side, and the two threaded holes are connected to the screw. If the operating block needs to be operated, the screw is loosened and separated from the threaded hole on the right side of the movable block 18, so that the operating block can move freely. After the operating block is not operated, the screw is connected to the threaded hole on the right side of the movable block 18, which ensures the limiting effect of gear three 21 on gear one 20. When the operating block is rotated, the rotation angle of the operating block is 360° or a multiple of 360°.

[0024] Embodiment 4: Based on embodiment 3, Figure 1-Figure 5As shown, the protection detection mechanism includes a working chamber 42 arranged 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, a telescopic motor shaft of the driving motor 41 passes through the center of the rotating disk 15 and the left end of the working shell 30 to enter the working chamber 42 and is fixedly connected with a fan-shaped bevel gear 43, a rotating shaft 38 is rotatably arranged between the front and rear ends of the working chamber 42, and bevel gears 40 are respectively arranged on the front and rear sides of the rotating shaft 38, and the bevel gear 40 is correspondingly meshed with the fan-shaped bevel gear 43, The rotating shaft 38 passes through the side end of the working chamber 42 and is fixedly connected to the gear 4 28 outside. The gear 4 28 meshes with the ring gear 27. The ring gear 27 is fixedly connected to the rotating sleeve 29. The front and rear ends of the protective shell 26 are penetrated with a through hole 1. The rotating sleeve 29 is rotatably arranged in the through hole 1 of the protective shell 26 on the front and rear sides. A plurality of flaw detection sensors or a plurality of cleaning brushes are evenly arranged in the circumferential direction in the through hole 2 of the rotating sleeve 29. The upper end of the protective shell 26 and the upper end of the rotating sleeve 29 are provided with a slot, and the slot is connected with the through hole 2. The telescopic motor shaft of the driving motor 41 is fixedly connected to the pulley 1 31, the pulley 1 31 is connected to the pulley 2 33 through the conveyor belt 32, the pulley 2 33 is fixedly connected to the fan gear 14 through the connecting shaft, the connecting shaft is rotatably connected to the base block 17 on the left side, the fan gear 14 is correspondingly meshed with the rack 13, the rack 13 is fixedly set on the left side of the upper end of the working plate 3, the conveyor belt 32 is in contact with the tensioning wheel 35, the tensioning wheel 35 is rotatably connected to the mounting seat 36, the mounting seat 36 is fixedly connected to the fixed plate 1 60 through a plurality of springs 1 37, the fixed plate 1 60 is fixedly connected to the base block 17 on the left side, and the mounting seat 36 is slidably connected to the base block 17 on the left side.

[0025] The working principle of the above technical solution is: The slot is opened for the transmission line to pass through and enter the through hole 2. 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 transmission line, thereby causing a safety accident. When the transmission line is being repaired, the fixed section of the telescopic motor shaft is fixedly connected to the pulley 1 31, the fixed section of the telescopic motor shaft is rotationally connected to the center of the rotating disk 2 15, and the movable section of the telescopic motor shaft is rotationally connected to the left end of the working shell 30, so that the telescopic motor shaft can be driven to freely extend and retract when the working shell 30 moves, and the rotation of the telescopic motor shaft will not drive the rotating disk 2 15 to rotate, and the driving motor 41 is controlled to work. The motor shaft of the driving motor 41 drives the pulley 1 31 and the fan-shaped bevel gear 43 to rotate, and the pulley 1 31 drives the pulley 2 33 to rotate through the conveyor belt 32, and the tensioning The arrangement of the wheel 35 is such that when the pulley 1 31 moves up and down with the movable block 18, the conveyor belt 32 drives the tensioning wheel 35 to move, and the tensioning wheel 35 drives the spring 1 37 to deform through the mounting seat 36, so that the conveyor belt 32 always keeps a tensioned state, so that the pulley 1 31 always drives the pulley 2 33 to rotate through the conveyor belt 32, and the pulley 2 33 drives the sector gear 14 to rotate through the connecting shaft. When the serrated segment of the sector gear 14 meshes with the rack 13, since the rack 13 is fixedly mounted on the working plate 3, the sector gear 14 rolls in the front and rear direction, thereby driving the base block 17 on the left side to slide along the upper end of the working plate 3 through the connecting shaft, and the base block 17 on the left side drives the fixed blocks 61 on the left and right sides, the guide slider 34 and the base block 17 on the right side to rotate simultaneously. The base blocks 17 on the left and right sides drive the movable blocks 18 on the left and right sides to move synchronously, the movable blocks 18 drive the protective shells 26 on the front and rear sides to move synchronously, the protective shells 26 drive the rotating sleeve 29 to move, and after the sawtooth segment of the sector gear 14 is disengaged from the rack 13, the base block 17 on the left side no longer moves, so that the protective shell 26 is in a stationary state. At this time, the sector bevel gear 43 begins to mesh with the bevel gear 40. Specifically, when the sector bevel gear 43 is meshed with the bevel gear 40 on the front side, the sector bevel gear 43 is not in a meshing state with the bevel gear 40 on the rear side. At this time, the sector bevel gear 43 drives the bevel gear 40 on the front side to rotate a certain angle, the bevel gear 40 on the front side drives the rotating shaft 38 to rotate a certain angle, and the rotating shaft 38 drives the gear four 28 to rotate A certain angle, gear four 28 drives the ring gear 27 to rotate a certain angle, after the fan bevel gear 43 is disengaged from the front bevel gear 40, when the fan bevel gear 43 is meshed 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 opposite direction by a certain angle, and the rotating shaft 38 drives the ring gear 27 to rotate in the opposite direction by a certain angle through gear four 28, thereby achieving the purpose of driving the ring gear 27 to rotate reciprocatingly, and during the reciprocating rotation of the ring gear 27, the protective shell 26 remains stationary, the ring gear 27 drives the rotating sleeve 29 to rotate reciprocatingly, and the rotating sleeve 29 drives the flaw detector to rotate reciprocatingly, so that the flaw detector performs all-round detection of the circumference of the transmission line, thereby improving the detection effect of the internal core of the transmission line.The flaw detector is connected to the alarm through the controller. After the flaw detector detects that the internal core of the transmission line is damaged, the controller controls the alarm to sound an alarm, reminding the maintenance personnel to repair the part of the transmission line corresponding to the flaw detector at this time. The flaw detector refers to CN202210753680-A high-voltage transmission line operation and maintenance equipment. When the fan-shaped bevel gear 43 and the bevel gears 40 on the front and rear sides are not engaged, the sawtooth section of the fan gear 14 is in a meshing state with the rack 13, so that the reciprocating rotation of the rotating sleeve 29 and the movement of the rotating sleeve 29 are intermittent, so that it is moved along the length direction of the transmission line while being repaired. The reciprocating rotation and movement of the rotating sleeve 29 only need to be driven by the driving motor 41, and there is no need for multiple electrical parts to cooperate with each other to drive, which is convenient for maintenance personnel to operate. If the direction of the transmission line is in an inclined state along the vertical plane, the control operation block is used to keep the inspection plate 39 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 the corresponding rotating sleeve 29 are restored to their original positions, and then the base plate 1 is moved to the same distance as the maximum stroke of the base block 17, and the transmission line is continued to be repaired. The moving direction of the base plate 1 is the same as the direction of the transmission line along the horizontal plane.

[0027] The working principle of the above technical solution is: The outlet of the liquid spray pipe 49 is provided with a blocking block. When cleaning the insulator, the maintenance personnel do not need to be on the maintenance plate 39. At this time, the telescopic cylinder 14 is controlled to extend and retract to drive the working plate 3 to rotate. As the working plate 3 rotates, the protrusion 16 is always in contact with the sliding plate 56. The liquid spray pipe 49 is a hose and can move freely. The telescopic cylinder 14 and the telescopic cylinder 2 are any one of a pneumatic telescopic cylinder, an electric telescopic cylinder and a hydraulic telescopic cylinder until the length direction of the working plate 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 passage through the slot. In hole 2, the flaw detection sensor in through hole 2 is replaced with a cleaning brush, and the driving motor 41 is controlled to work so that the rotating sleeve 29 rotates and moves intermittently. The cleaning brush cleans the peripheral side of the insulator and gradually moves along the length of the insulator to clean the insulator. When the guide slider 34 moves with the base block 17 on the left, the external protrusion 16 can be driven to rotate through the guide rod 12. When the protruding section of the protrusion 16 contacts the sliding plate 56, the sliding plate 56 is pushed to move. The spring 2 52 is compressed. After the protruding section of the protrusion 16 is out of contact with the sliding plate 56, Under the elastic action of the second spring 52, the sliding plate 56 returns to its original position, the sliding plate 56 drives the second matching block 55 to move left and right, the second matching block 55 drives the first matching block 54 to move up and down, the first matching block 54 drives the push block 48 to move up and down through the connecting plate 53, the push block 48 drives the push plate 59 to move up and down, when the push plate 59 moves downward, the push plate 59 pushes the cleaning liquid in the pressure chamber into the spray pipe 49, opens the block at the outlet of the spray pipe 49, and makes the spray pipe 49 spray the cleaning liquid to the rear side of the second through hole, thereby cleaning the insulator, and the push plate 59 When moving upward, the cleaning liquid stored in the storage box 45 enters the pressure chamber through the outlet under the action of gravity, and the pressure chamber is replenished with liquid. The setting of the guide plate 57 ensures that the flow direction of the cleaning liquid is from the storage box 45 to the pressure chamber, and the spray pipe 49 sprays liquid when the rotating sleeve 29 moves, and the pressure chamber is replenished with liquid when the rotating sleeve 29 rotates. At this time, the spray pipe 49 does not spray liquid, and then the insulator is further brushed with a cleaning brush, thereby improving the cleaning efficiency of the insulator. The above cleaning process does not require manual cleaning, which saves time and effort and avoids safety hazards.
