[0020] In the description of the present invention, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention.

[0021] The present invention will be further described below with reference to the accompanying drawings.

[0022] like Figures 2 to 5 , in order to solve the problem that the self-cleaning part interferes with the insulation effect.

[0023] The fixing frame 11 is detachably connected to a splint 103 by means of screws and nuts. An umbrella-shaped ceramic part 00 is provided below the fixing frame 11. Two slide rails 101 are rotatably connected to both sides of the lower end of the fixing frame 11. Each slide rail 101 is slidably connected to a chuck 105, and a cleaning mechanism is provided between the two chucks 105.

[0024] When installing this insulator, first fix the top of the umbrella-shaped ceramic part 00 to the cable support structure, and fix the cable to the bottom of the umbrella-shaped ceramic part 00. Then, place the fixing frame 11 on the cable support structure, and then use the clamping plate 103 to clamp the support structure. The fixing frame 11 and the clamping plate 103 are both provided with strip-shaped assembly slots. Custom screws and nuts that pass through the assembly slots can be detachably connected to adapt to the width of different support structures. Initially, the two slide rails 101 are in an upward folded state. At this time, the clamping head 105 fixes the cleaning mechanism directly below the fixing frame 11. When cleaning, the two slide rails 101 rotate downward from the fixing frame 11 to form an extended symmetrical track. Then, the two clamping heads 105 are driven downward, which in turn drives the cleaning mechanism to move from top to bottom, so that the cleaning mechanism cleans the umbrella-shaped ceramic part 00 layer by layer, thereby removing impurities such as bird droppings and dust attached to it, thereby ensuring the insulation effect of the umbrella-shaped ceramic part 00.

[0025] like Figures 2 to 8 , in order to solve the problem of cleaning the umbrella-shaped ceramic part 00 by the cleaning mechanism.

[0026] The cleaning mechanism includes two lifting platforms 12, each of which can be detachably connected to the corresponding chuck 105. The two lifting platforms 12 are rotatably connected to a second rotating ring 13, and the second rotating ring 13 is fixed with two symmetrically arranged brackets 301. Each bracket 301 is rotatably connected to a cleaning rod 303.

[0027] A snap-fit ​​assembly is provided between the chuck 105 and the corresponding lifting platform 12 for quick docking, facilitating assembly and disassembly during processing. When the chuck 105 moves, the lifting platform 12 is synchronously moved up and down, thereby driving the second rotating ring 13 to move in the vertical direction of the umbrella-shaped ceramic piece 00, so that the cleaning rod 303 can closely contact the curved surface of the umbrella skirt of the umbrella-shaped ceramic piece 00. When the second rotating ring 13 is driven to rotate, the bracket 301 on it rotates accordingly, and the corresponding cleaning rod 303 moves accordingly. The front end of the cleaning rod 303 is provided with a brush, which can clean the surface of the umbrella-shaped ceramic piece 00 through friction.

[0028] like Figures 2 to 8 , to further increase the cleaning effect.

[0029] A first rotating ring 203 is rotatably connected between the two lifting platforms 12. Each cleaning rod 303 is provided with a bevel gear 304. A bevel gear ring is provided on the side of the first rotating ring 203. The bevel gear 304 is meshed with the bevel gear ring.

[0030] When the second rotating ring 13 rotates, it drives the bracket 301 to rotate synchronously, and the bevel gear 304 connected to the bracket 301 rotates. When the second rotating ring 13 rotates, the first rotating ring 203 rotates synchronously in the opposite direction. At this time, the bevel gear 304 and the first rotating ring 203 move relative to each other, and then the bevel gear ring on the first rotating ring 203 engages to drive the bevel gear 304 to rotate, thereby driving the cleaning rod 303 to rotate synchronously.

[0031] like Figure 7 and Figure 8 , in order to solve the problem that the cleaning rod 303 cleans the umbrella-shaped ceramic part 00 layer by layer.

[0032] Each bracket 301 is fixedly connected to an electric telescopic rod 302 , a movable end of each electric telescopic rod 302 is fixedly connected to a fixed plate, and each cleaning rod 303 is rotatably connected to the corresponding fixed plate.

[0033] The cleaning rod 303 is provided with a slide groove, through which the bevel gear 304 is slidably connected to the cleaning rod 303, so that the reciprocating movement of the cleaning rod 303 does not affect the tooth meshing between the bevel gear 304 and the first rotating ring 203. When the first rotating ring 203 and the second rotating ring 13 rotate to clean the umbrella-shaped ceramic member 00, the electric telescopic rod 302 is in a retracted state, thereby driving the fixed plate, so that the inner end of the cleaning rod 303 is close to the inside of the umbrella-shaped ceramic member 00. The brush at the front end of the cleaning rod 303 is round, so when the cleaning rod 303 rotates, it can clean the surface of the umbrella-shaped ceramic member 00. The splint 103 drives the cleaning mechanism to move from top to bottom as a whole, and then cleans the umbrella-shaped ceramic piece 00 layer by layer from top to bottom. After each layer is cleaned, the electric telescopic rod 302 is driven to extend. At this time, the cleaning rod 303 is pulled between the umbrella-shaped ceramic piece 00 and the splint 103. At this time, the splint 103 drives the lifting platform 12 to move downward. The cleaning rod 303 does not affect the movement. After the cleaning rod 303 moves to the lower layer, the electric telescopic rod 302 retracts. Similarly, the cleaning rod 303 moves into the umbrella-shaped ceramic piece 00 for cleaning, thereby achieving the purpose of cleaning the umbrella-shaped ceramic piece 00 layer by layer. At the same time, the electric telescopic rod 302 makes it easy to control the cleaning rod 303 to extend to different lengths, thereby meeting the cleaning requirements of different umbrella-shaped ceramic pieces 00. A sliding groove is provided on the cleaning rod 303, and the bevel gear 304 is slidably connected to the cleaning rod 303 through the sliding groove thereon, so that the reciprocating movement of the cleaning rod 303 does not affect the tooth meshing on the bevel gear 304 and the first rotating ring 203.

[0034] like Figures 6 to 8, in order to solve the problem of the rotation of the second rotating ring 13.

[0035] Each gear 201 is rotatably connected to the corresponding lifting platform 12 . A first tooth shape is provided on one side of the second rotating ring 13 . The first tooth shape is engaged with the two gears 201 .

[0036] In order to solve the problem of inconvenient driving of the second rotating ring 13 and the complexity of controlling the rotation angle separately, the gear 201 is engaged with the first tooth profile on the second rotating ring 13. The driving gear 201 can engage and drive the second rotating ring 13 to rotate stably, simplifying the transmission structure and facilitating the control of the cleaning rod 303 to clean around the umbrella-shaped ceramic piece 00.

[0037] like Figures 6 to 8 , in order to solve the problem that the cleaning rod 303 rotates around the umbrella-shaped ceramic part 00 while rotating on its own to clean it.

[0038] The first tooth profile is provided on the inner side of the second rotating ring 13 , and the second tooth profile is provided on the outer side of the first rotating ring 203 . The gear 201 is meshed with the second tooth profile.

[0039] In order to ensure that the cleaning rod 303 rotates to increase the cleaning effect on the umbrella-shaped ceramic part 00, when the gear 201 rotates and drives the second rotating ring 13 to rotate, the cleaning rod 303 follows and moves around the umbrella-shaped ceramic part 00, thereby driving the bevel gear 304 to move relative to the first rotating ring 203, and then being meshed and driven to rotate. The rotation of the cleaning rod 303 itself is synchronized with its movement around the umbrella-shaped ceramic part 00. At this time, the brush on the cleaning rod 303 rolls on the surface of the umbrella-shaped ceramic part 00, affecting the cleaning effect. Then, in the present invention, the first rotating ring 203 is driven to rotate by the meshing of the gear 201 and the second tooth shape, thereby increasing the meshing drive speed of the first rotating ring 203 on the bevel gear 304, thereby increasing the rotation speed of the cleaning rod 303 itself and enhancing the cleaning effect on the umbrella-shaped ceramic part 00. Through the rotation of a single gear 201, the cleaning rod 303 is controlled to rotate around the umbrella-shaped ceramic part 00 while rotating to clean it, thereby facilitating the control of the start and stop of the cleaning rod 303, so that it can clean the umbrella-shaped ceramic part 00 layer by layer.

[0040] like Figures 2 to 5 , to solve the problem of the cleaning mechanism moving up and down.

[0041] A wire wheel 102 is rotatably connected to the fixed frame 11 , and two lifting wires 104 are wound around the wire wheel 102 . The other end of each lifting wire 104 is fixedly connected to a corresponding clamp 105 .

[0042] Initially, the two lifting lines 104 are wound around the pulley 102, driving the pulley 102 to rotate. At this time, the lifting lines 104 are released, and the cleaning mechanism moves downward at the same time as the chuck 105 due to its own gravity; similarly, when the pulley 102 rotates in the opposite direction, the lifting lines 104 are wound around it, thereby achieving the purpose of controlling the cleaning mechanism to move upward.

[0043] like Figures 2 to 9 , in order to realize the control of each part during the cleaning process of the insulator itself.

[0044] A first motor is provided on the fixing frame 11 , and a second motor is provided on one of the lifting platforms 12 . The first motor, the second motor and the electric telescopic rod 302 are all controlled by a control circuit.

[0045] The output shaft of the first motor is connected to the reel 102, and the output shaft of the second motor is connected to the gear 201. The first motor, the second motor and the electric telescopic rod 302 are all controlled by the control circuit. The control circuit can adopt timing setting or remote control. Relying on the unified scheduling of the control circuit, the motor drive and the telescopic rod movement are precisely coordinated, making the cleaning process automated and coherent, and improving cleaning efficiency and effect.

[0046] like Figure 9 , in order to solve the problem of extending and storing the rotating rod 106 each time cleaning.

[0047] Two rotating rods 106 are fixedly connected to each slide rail 101 , and two pushing rods 202 are fixedly connected to each lifting platform 12 .

[0048] Initially, the push rod 202 contacts the rotating wheel 107, thereby supporting the rotating rod 106 and tilting it upward, thereby ensuring that the slide rail 101 is in an upward folded and stored state, avoiding affecting the insulation effect of the insulator. When the lifting platform 12 moves downward, the push rod 202 moves with it, gradually reducing its support for the rotating rod 106, thereby causing the rotating rod 106 to rotate, and then the slide rail 101 rotates under its own gravity and becomes vertical. Permanent magnets that can attract each other are set between each slide rail 101 and the fixed frame 11 to ensure its stability after extension. Each push rod 202 is fixed below the lifting platform 12, ensuring that the chuck 105 moves downward onto the slide rail 101 only after the slide rail 101 moves to a fixed position. The setting of the rotating wheel 107 can convert the sliding friction between the push rod 202 and the rotating rod 106 into rolling friction, reducing resistance.

[0050] S1: Cut the clay raw materials into umbrella-shaped ceramic pieces of different diameters and lengths according to the required insulation effect;

[0051] S2: sintering and shaping it into an umbrella-shaped ceramic piece 00;

[0052] S3: Set different slide rails 101 according to the length of the umbrella-shaped ceramic piece 00, and then install and fix the cleaning mechanism between the two chucks 105;

[0053] S4: Pair and package the umbrella-shaped ceramic piece 00 and the fixing frame 11.
