[0002] An insulator is a special insulating control component that plays an important role in overhead transmission lines. A porcelain insulator is an insulator made of electrical porcelain, and the electrical porcelain is baked from quartz, feldspar, and clay as raw materials. The porcelain surface of the porcelain insulator is usually covered with porcelain glaze to improve its mechanical strength, prevent water infiltration, and increase surface smoothness. Among various insulators, porcelain insulators are the most commonly used.

[0016] S1: First, fix the insulator body so that the insulator body is in a vertical state;

[0017] S2: Then aim the image acquisition camera at one side of the insulator body, and at the same time adjust the distance between the image acquisition camera and the insulator body (1) so that the first mounting seat and the second mounting seat at both ends of the insulator body are within the shooting range;

[0018] S3: Then, operate the image acquisition camera to shoot the surface of the insulator body. During this process, intermittently rotate the insulator body to enable the image acquisition camera to shoot the surroundings of the insulator body. Upload the image information to the computer to detect the image and judge whether there are defects on the surface of the insulator body;

[0019] S4: After the detection is completed, remove the insulator body.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] 1. By setting the position-adjusting rotating member, rotating exhaust member, and one-way pulling unit, when the wind blows the wind vane plate, the reversing bevel gear will drive the transmission shaft to rotate clockwise, thereby causing the reciprocating lead screw to rotate clockwise. During this process, the second follower gear rotates counterclockwise. At this time, the second sleeve rotates relative to the transmission shaft. When the transmission gear ring rotates counterclockwise, the reversing bevel gear will drive the transmission shaft to rotate clockwise through the second follower gear, second sleeve, second pawl, and second ratchet ring, so that the reciprocating lead screw always rotates clockwise. In this way, when the second pawl rotates, the reciprocating lead screw always rotates clockwise, thus realizing the one-way rotation of the reciprocating lead screw, so that the reciprocating moving distance of the movable sleeve block is always equal. Then, in cooperation with the rotating exhaust member and the one-way pulling unit, the surface of the insulator body can be cleaned by the airflow, thus achieving the self-cleaning effect.

[0022] 2. By setting the rotating exhaust member and the one-way pulling unit, when the movable sleeve block drives the pin to contact the C-shaped clamping plate, the pin will be extruded by the inclined surface at one end of the pin, causing the pin to move relative to the plug pin. When the pin aligns with the locking hole, the pin will be inserted into the locking hole under the elastic restoring force of the third return spring. When the movable sleeve block moves away from the air storage chamber, it will drive the piston rod to move through the pin and the locking hole, so that the outside air enters the air storage chamber through the rotating exhaust member. When the partition plate contacts one end of the L-shaped guide rod as the movable sleeve block moves, the partition plate will be blocked, causing the first return spring to be compressed, so that the guide rail moves relative to the side connecting shaft, so that the plug pin drives the pin to move downward, so that the pin is separated from the locking hole. At this time, the piston rod will be restored under the elastic restoring force of the second return spring, so that the piston rod discharges the air inhaled into the air storage chamber, thus achieving the effect of supplying air to the rotating exhaust member and realizing the intermittent exhaust effect of the rotating exhaust member.

The following describes the embodiments according to the overall structure of the present invention.

[0034] Please refer to Figures 1 to 8 , in an embodiment of the present invention, an anti-fouling self-cleaning line post porcelain insulator includes an insulator main body 1, a first mounting seat 2, and a second mounting seat 3. A first clamping seat 20 is installed on the outer wall of the second mounting seat 3. A connection chamber 19 is installed on one side of the first clamping seat 20 away from the second mounting seat 3. An adjustment and rotation member is provided on the connection chamber 19. A reciprocating lead screw 9 is connected to the connection chamber 19 through the adjustment and rotation member. At one end of the connection chamber 19 away from the first clamping seat 20, L-shaped guide rods 10 are installed on both sides of the reciprocating lead screw 9. A movable sleeve block 23 is sleeved on the reciprocating lead screw . The movable sleeve block 23 is slidably connected to the L-shaped guide rods 10. Gas storage chambers 11 are installed on both sides of the connection chamber 19. A piston rod 24 extending outside the gas storage chamber 11 is inserted into the interior of the gas storage chamber 11. A second return spring 45 connected to the piston rod 24 is provided on the inner wall of the gas storage chamber 11. One-way pulling units connected to the piston rod 24 are provided at both ends of the movable sleeve block 23. A rotary exhaust member is provided on the gas storage chamber 11.

[0035] In this embodiment, during the use of the insulator body 1, the position-adjusting rotating member is driven by wind power to operate. Through the operation of the position-adjusting rotating member, the reciprocating lead screw 9 only rotates clockwise. During the rotation of the reciprocating lead screw 9, the movable sleeve block 23 reciprocates along the reciprocating lead screw 9. When the movable sleeve block 23 approaches the connection bin 19, the operation of the one-way pulling unit causes the movable sleeve block 23 to be connected to the piston rod 24. When the movable sleeve block 23 moves to the end of the reciprocating lead screw 9 away from the connection bin 19, the piston rod 24 pumps external air into the air storage bin 11. At the same time, the movable sleeve block 23 is separated from the piston rod 24. At this time, the piston rod 24 will be restored under the elastic restoring force of the second return spring 45, so that the air inside the air storage bin 11 is sprayed on the surface of the insulator body 1 through the rotary exhaust member, so as to realize the self-cleaning of the insulator body 1.

[0036] Please refer specifically to Figure 1 , Figure 2 , Figure 3 , Figure 4 , the position-adjusting rotating member includes a second clamping seat 21 installed on the top of the first clamping seat 20. One end of the second clamping seat 21 is installed with a second positioning ring 8. The outer wall of the second positioning ring 8 is rotatably connected with a transmission gear ring 16 through a bearing. The top of the transmission gear ring 16 is installed with a first positioning ring 7. The top of the first positioning ring 7 is provided with a wind vane plate 17. The inside of the connection bin 19 is rotatably connected with a transmission shaft 36 through a bearing. One end of the transmission shaft 36 is fixedly connected with one end of the reciprocating lead screw 9. The top of the connection bin 19 is provided with a rotating link 28 extending into the connection bin 19. The top of the rotating link 28 is installed with a transmission spur gear 25 meshing with the transmission gear ring 16. The bottom of the rotating link 28 is installed with a reversing bevel gear 29. A first ratchet ring 31 is arranged on the transmission shaft 36. A first sleeve 32 located on one side of the first ratchet ring 31 is rotatably connected to the transmission shaft 36 through a bearing. One end of the first sleeve 32 away from the first ratchet ring 31 is installed with a first follower gear 33 meshing with the reversing bevel gear 29. A second sleeve 35 is arranged on the transmission shaft 36 on the side of the rotating link 28 away from the first sleeve 32. One end of the second sleeve 35 is provided with a second follower gear 34 meshing with the reversing bevel gear 29. A second ratchet ring 37 is arranged on the transmission shaft 36 at the end of the second sleeve 35 away from the second follower gear 34. The outer wall of the first sleeve 32 is provided with a first pawl 30 meshing with the first ratchet ring 31. The outer wall of the second sleeve 35 is provided with a second pawl 38 meshing with the second ratchet ring 37.

[0037] In this embodiment, when the wind blows the wind blade plate 17, the wind blade plate 17 drives the transmission gear ring 16 to rotate through the first positioning ring 7. At this time, the transmission gear ring 16 will drive the transmission spur gear 25 to rotate. When the wind blade plate 17 drives the transmission gear ring 16 to rotate clockwise through the first positioning ring 7, the transmission spur gear 25 will drive the reversing bevel gear 29 to rotate through the rotating link 28. At this time, the reversing bevel gear 29 will drive the transmission shaft 36 to rotate clockwise through the first follower gear 33, the first sleeve 32, the first pawl 30, and the first ratchet ring 31, so as to make the reciprocating lead screw 9 rotate clockwise. During this process, the second follower gear 34 rotates counterclockwise. At this time, the second sleeve 35 rotates relative to the transmission shaft 36. When the transmission gear ring 16 rotates counterclockwise, at this time, the reversing bevel gear 29 will drive the transmission shaft 36 to rotate clockwise through the second follower gear 34, the second sleeve 35, the second pawl 38, and the second ratchet ring 37, so as to make the reciprocating lead screw 9 always rotate clockwise. In this way, when the second pawl 38 rotates, the reciprocating lead screw 9 always rotates clockwise. In this way, the one-way rotation of the reciprocating lead screw 9 can be realized, so that the distance that the movable sleeve block 23 reciprocates is always equal.

[0038] Please refer specifically to Figure 4 , the tooth orientations of the first ratchet ring 31 and the second ratchet ring 37 are equal, and the first pawl 30 and the second pawl 38 are both clamped to the first sleeve 32 and the second sleeve 35 through torsion springs.

[0039] In this embodiment, by setting this structure, when the rotating link 28 rotates, the transmission shaft 36 always rotates in one direction, so as to realize the one-way rotation of the reciprocating lead screw 9.

[0040] Please refer specifically to Figure 3 、 Figure 8 , the number of wind blade plates 17 is set to be multiple, and the multiple wind blade plates 17 are equidistantly distributed along the center of the first positioning ring 7.

[0041] In this embodiment, by setting this structure, the wind can blow the first positioning ring 7 to rotate from different directions.

[0042] Please refer specifically to Figure 2 、 Figure 3 、 Figure 5 、 Figure 6 、 Figure 7, the unidirectional pulling unit includes a C-shaped clamping plate 41 installed at one end of the piston rod 24 away from the air storage bin 11. A locking hole 46 is provided on the C-shaped clamping plate 41. The two ends of the movable sleeve block 23 are inserted with pins 49. The outside of the pin 49 is inserted with a locking pin 47. A third return spring 48 connected to the inner wall of the locking pin 47 is arranged at the top of the pin 49. Side connecting shafts 50 located below the locking pin 47 are arranged on both sides of the pin 49. A guide rail 51 is sleeved on the outside of the side connecting shaft 50. A first return spring 43 is installed on one side of the movable sleeve block 23 away from the C-shaped clamping plate 41. One end of the first return spring 43 is provided with a baffle plate 42 connected to the guide rail 51.

[0043] In this embodiment, when the movable sleeve block 23 drives the locking pin 47 to contact the C-shaped clamping plate 41, the locking pin 47 will be squeezed by the inclined surface at one end of the locking pin 47, causing the locking pin 47 to move relative to the pin 49. When the locking pin 47 is aligned with the locking hole 46, the locking pin 47 will be inserted into the locking hole 46 under the action of the elastic restoring force of the third return spring 48. When the movable sleeve block 23 moves away from the air storage bin 11, it will drive the piston rod 24 to move through the locking pin 47 and the locking hole 46, so that the outside air enters the air storage bin 11 through the rotary exhaust part. When the baffle plate 42 contacts one end of the L-shaped guide rod 10 as the movable sleeve block 23 moves, the baffle plate 42 will be blocked, causing the first return spring 43 to be squeezed, so that the guide rail 51 moves relative to the side connecting shaft 50. In this way, the pin 49 can drive the locking pin 47 to move downward, so that the locking pin 47 is separated from the locking hole 46. At this time, the piston rod 24 will be restored by the elastic restoring force of the second return spring 45, so that the piston rod 24 discharges the air inhaled into the air storage bin 11, thus realizing the effect of supplying air to the rotary exhaust part and realizing the intermittent exhaust effect of the rotary exhaust part.

[0044] Please refer specifically to Figure 7 , the guide rail 51 is composed of an inclined section 511 and a horizontal section 512. The diameter of the side connecting shaft 50 is equal to the inner wall width of the guide rail 51.

[0045] In this embodiment, by setting this structure, the pin 49 cannot move relative to the movable sleeve block 23 when the side connecting shaft 50 is located at the horizontal section 512 position. When the side connecting shaft 50 moves to the inclined section 511 position, the pin 49 will move through the inclined section 511 and the side connecting shaft 50, so as to realize the precise limit of the pin 49.

[0046] Please refer specifically to Figure 7 , one end of the C-shaped clamping plate 41 is provided with an inclined surface. The diameter of the locking pin 47 is equal to the diameter of the locking hole 46. A ball is rotatably connected to the top of the locking pin 47 through a rotating shaft.

[0047] In this embodiment, this structure is provided to reduce the friction between the top of the bayonet 47 and the locking hole 46 , while also improving the stability of the bayonet 47 when inserted into the locking hole 46 .

[0048] Please refer to Figure 3 、 Figure 5 、 Figure 6 、 Figure 8 The rotary exhaust member includes a worm gear ring 18 rotatably connected to the outside of the second mounting seat 3. The worm gear ring 18 is located above the first clamping seat 20. An injection pipe 6 is installed on the top of the worm gear ring 18. A nozzle head 5 is provided on the side of the injection pipe 6 close to the insulator body 1. The top of the air storage bin 11 is rotatably connected to a worm gear 22 meshing with the worm gear ring 18 through a bearing. Small transmission bevel gears 4 are installed at both ends of the worm gear 22. A shift gear 44 is provided on the top of the air storage bin 11. The top of the shift gear 44 is provided with a small transmission bevel gear. A large transmission bevel gear 27 is meshed with the gear 4, and a support rod 40 is provided on one side of the C-shaped clamping plate 41. One end of the support rod 40 is provided with a shift rack 26 meshed with the shift gear 44. An air intake pipe 15 is installed at one end of the air storage bin 11, and a first one-way valve 13 is provided at one end of the air intake pipe 15. A filter bin 14 is provided at the bottom of the first one-way valve 13, and a second one-way valve 39 is provided at one end of the air storage bin 11, which is located above the air intake pipe 15. One end of the second one-way valve 39 is connected to a hose 12 connected to the jet pipe 6.

[0049] In this embodiment, when the piston rod 24 moves in a direction away from the air storage bin 11, outside air enters the air storage bin 11 through the filter bin 14, the first one-way valve 13, and the air inlet pipe 15. At the same time, the shift rack 26 shifts the shift gear 44 to rotate, thereby causing the large transmission bevel gear 27 to drive the worm gear ring 18 to rotate 180 degrees through the small transmission bevel gear 4 and the worm gear 22. When the piston rod 24 is restored under the action of the elastic restoring force of the second return spring 45, the air sucked into the air storage bin 11 through the piston rod 24 will pass through the second one-way valve 39, the hose 12, the injection pipe 6, and finally be ejected by the injection head 5, so that the air is sprayed on the surface of the insulator body 1. Thereafter, the shift rack 26 drives the shift gear 44 to rotate in the opposite direction, causing the injection head 5 to rotate during the injection process, so that the surface of the insulator body 1 can be cleaned by the airflow, thereby achieving a self-cleaning effect.

[0050] Please refer to Figure 6 The air inlet of the first one-way valve 13 is connected to the filter bin 14 , and the air inlet of the second one-way valve 39 is connected to the air storage bin 11 .

[0051] In this embodiment, this structure is provided to achieve a one-way flow of air inside the air storage bin 11 .

[0052] Please refer toFigure 2 , Figure 3 The centers of the worm gear ring 18, the second positioning ring 8, and the insulator body 1 are coaxial.

[0053] In this embodiment, by setting this structure, the distance between the insulator body 1 and the jet head 5 remains constant when the jet pipe 6 rotates.

[0054] The following provides a detection method for a pollution-proof and self-cleaning line post insulator in combination with the above-mentioned pollution-proof and self-cleaning line post insulator, which specifically includes the following steps:

[0055] S1: First, fix the insulator body 1 so that the insulator body 1 is in a vertical state;

[0056] S2: Then, aim the image acquisition camera at one side of the insulator body 1, and at the same time adjust the distance between the image acquisition camera and the insulator body 1 so that the first mounting seat 2 and the second mounting seat 3 at both ends of the insulator body 1 are within the shooting range;

[0057] S3: Then, operate the image acquisition camera to take pictures of the surface of the insulator body 1. During this process, intermittently rotate the insulator body 1 so that the image acquisition camera takes pictures of the surroundings of the insulator body 1.
