Description

Technical Field

[0001] This invention relates to the field of insulator testing technology, and in particular to a non-destructive testing device for the bonding strength of the adhesive interface of porcelain insulators. Background Technology

[0002] Porcelain insulators are electrical insulating products made of electrical ceramics. Their porcelain surfaces are typically covered with a porcelain glaze to improve mechanical strength and prevent water seepage. Non-destructive testing of the bonding strength of the adhesive interface of porcelain insulators refers to a technical method that assesses the bonding strength and internal defects of the adhesive composite interface formed between the metal fittings and the porcelain component using cement adhesive, without damaging the insulator itself. In practical applications, ultrasonic testing technology is widely used to detect internal defects in the adhesive parts of porcelain insulators. With technological advancements, testing systems integrating intelligent sensors and intelligent sensing elements can achieve accurate acquisition, real-time processing, and intelligent analysis of ultrasonic signals. Furthermore, industrial vision and visual intelligence technologies are introduced to assist in imaging and intelligent identification of the appearance, sensor positioning, and defect characterization of the adhesive interface, thus forming a multi-dimensional complement to ultrasonic data. Simultaneously, the reliable operation and industry promotion of the entire testing system rely on the comprehensive integration of fundamental support capabilities such as new material testing, metrology, related standardization, and certification and accreditation services.

[0003] When using ultrasonic testing to check the bonding strength of porcelain insulators, a coupling agent such as glycerin or machine oil needs to be applied. Existing equipment is prone to uneven application, affecting signal stability and interpretation accuracy.

[0023] In this invention, the dustproof coating detection component 5 further includes: Two guide wheel frames 521 are arranged opposite each other on the lower side of the suspension plate 508, and guide wheels 527 are respectively provided inside the two guide wheel frames 521; Two lifting plates 514 are respectively installed inside the corresponding slide rail frame 510.

The other ends of the multiple telescopic springs 515 are respectively fixedly connected to the inner wall of the corresponding slide rail frame 510. Two connecting ropes 519 are provided, with one end of each rope being mounted on the same mounting block 520, and the other ends of each rope being fixedly connected to the corresponding lifting plate 514 after passing over the corresponding guide wheel 527.

[0024] In this invention, the dustproof coating detection component 5 further includes: A compression oil cylinder 509 is provided on the lower side of one of the lifting plates 514, and an oil brush holder 517 is also provided on the lower side of one of the lifting plates 514. Two oil equalization cylinders 525 are mounted on an oil brush holder 517. An oil brush body 518 is also mounted on the lower side of the oil brush holder 517. The two oil equalization cylinders 525 are connected to the inside of the oil brush body 518. Two oil supply pipes 526, one end of which is set on the oil compression cylinder 509, and the other end of which is respectively inserted into the interior of the corresponding oil equalization cylinder 525; Two oil pumps 524 are respectively installed on the outer wall of the corresponding oil pipeline 526.

[0025] In this invention, the dustproof coating detection component 5 further includes: The oil recovery cylinder 513 is located on the lower side of another lifting plate 514, and an oil scraper 522 is also located on the lower side of the other lifting plate 514. Oil scraper plate 523 is located on the lower side of oil scraper frame 522. Two oil suction pipes 528 are provided on the upper side of oil scraper plate 523. The other ends of the two oil suction pipes 528 are inserted into the inside of recovery oil cylinder 513. Two oil pumps 529 are installed on the outer wall of the corresponding oil pipe 528.

[0026] In this invention, the dustproof coating detection component 5 further includes: Two rotating shafts 507 are respectively mounted on the movable block 503. One end of each rotating shaft 507 is provided with a movable gear 506, and the two movable gears 506 respectively mesh with the corresponding semi-circular toothed rings 502. Two moving motors 13 are located inside the moving block 503, and the drive ends of the two moving motors 13 are respectively connected to the other end of the corresponding rotating shaft 507 through couplings.

[0027] Specifically, after the two porcelain insulator bodies 7 are fixed, the drive motor 8 is turned on to drive the bidirectional lead screw 9 to rotate, thereby bringing the two moving plates 10 closer together. During this process, the two semi-circular dust-proof chambers 501 move closer together and merge into a complete and sealed annular dust-proof chamber, and multiple semi-circular toothed rings 502 merge into two complete circular toothed rings. At this time, the detection position of the porcelain insulator adhesive interface is located inside the annular dust-proof chamber and is completely isolated from the outside. Subsequently, the two moving motors 13 are turned on to drive the two rotating shafts 507 to rotate the corresponding moving gears 506. Since the two moving gears 506 mesh with the corresponding semi-circular toothed rings 502, the two moving gears 506 can drive the moving block 503 along the complete and sealed annular... The complete moving groove inside the dust-proof chamber moves around the porcelain insulator adhesive interface. When detecting the detection position of the porcelain insulator adhesive interface, the moving block 503 first moves the oil brush body 518 to the starting point of the detection position. Then, by turning on the two oil pumps 524, the oil inside the compressed oil cylinder 509 is delivered to the inside of the two oil equalization cylinders 525 through the two oil pipes 526. With the buffer of the two oil equalization cylinders 525, the oil evenly wets the oil brush body 518. Then, driven by the moving block 503, the oil brush body 518 evenly applies oil to the detection position from the starting point to the ending point. After the oiling is completed, the extension of the electric telescopic rod 516 moves the ultrasonic detector 512 closer to the detection position until the ultrasonic detector 512 contacts the detection position. With coupling oil as the medium, the ultrasonic detector 512 tests the bonding strength of the porcelain insulator's adhesive interface. When the ultrasonic detector 512 approaches the detection position, the setting block 520 moves and pulls the two connecting ropes 519. Since the two lifting plates 514 are connected to the setting block 520 via their respective connecting ropes 519, when the two connecting ropes 519 are pulled, the two lifting plates 514 overcome the elastic force of the corresponding telescopic springs 515 and rise along the corresponding slide rails 510, thereby moving the oil brush body 518 and the scraper plate 523 away from the detection position to avoid obstructing the ultrasonic detector 512's detection work. After the detection at this position is completed, the ultrasonic detector is moved away by the retraction of the electric telescopic rod 516. When device 512 moves away from the detection position, and the two lifting plates 514 lack the tension of the corresponding connecting ropes 519, the two telescopic springs 515 push the oil brush body 518 and the oil scraper plate 523 to contact the end and start points of the detection position again. When applying oil to the next detection area, the moving block 503 drives the oil brush body 518 to move and apply oil to the next detection area. As the oil scraper plate 523 moves in the previous detection area, it scrapes off the residual oil on its surface. At the same time, by turning on the two oil pumps 529, the residual oil adhering to the surface of the oil scraper plate 523 enters the interior of the oil scraper plate 523 through the holes, and then is transported by the two oil pipes 528 to finally enter the recovery oil cylinder 513 for recovery.This allows for the cleaning and collection of residual engine oil after testing without interrupting the testing process.

[0028] In specific application scenarios, two semi-circular dust-proof chambers 501 are combined into a complete, sealed annular dust-proof chamber, completely isolating the detection position from the outside world. This effectively prevents dust and impurities from interfering with ultrasonic detection, ensuring a clean detection environment and improving detection reliability. Multiple semi-circular toothed rings 502 are combined in pairs to form a complete circular toothed ring, providing a continuous and stable annular meshing track for the moving gear 506. This ensures that the moving block 503 can move smoothly and uninterruptedly around the entire circumference of the detection position. The oil pump 524 delivers oil through the oil pipe 526 into the oil distribution cylinder 525. After being buffered by the oil distribution cylinder 525, the oil brush is evenly soaked, ensuring consistent oil application and uniform coating, improving the quality of the coupling agent coverage, and providing a stable medium for ultrasonic detection. The electric telescopic rod 516 can flexibly control the ultrasonic detector 512 to move closer to or away from the detection position, ensuring precise positioning after oiling. The contact with the ceramic surface avoids interference between the oiling process and the detection, ensuring that the detection action is independent and controllable. When the ultrasonic detector 512 approaches, the setting block 520 pulls the connecting rope 519, causing the lifting plate 514 to rise against the elastic force of the telescopic spring 515, automatically lifting the oil brush body 518 and the oil scraper plate 523 away from the detection position. After the ultrasonic detector 512 retracts, the telescopic spring 515 resets, causing the oil brush body 518 to re-contact the detector. This structure requires no additional power and cleverly achieves automatic avoidance between the oiling and detection actions, avoiding interference. During the movement, the oil scraper plate 523 scrapes away the residual oil after detection, and the oil collected in the oil scraper plate 523 is recovered into the recovery oil cylinder 513 through the oil pump 529 and the oil pipe 528 via the oil extraction pipe, realizing online cleaning and recovery without interrupting the detection process. This keeps the detection area clean and saves coupling agent resources.

[0029] Reference Figure 1 , Figure 2 and Figure 8 In a preferred embodiment, the clamping component 6 further includes: The movable seat 607 is mounted on two movable rails 608, and a clamping groove plate 601 is provided on the upper side of the movable seat 607. Two fixing slotted plates 604 are arranged opposite each other on one side of the clamping slotted plate 601.

[0030] In this invention, the clamping assembly 6 further includes: Two movable blocks 602 are disposed opposite each other inside the clamping slot plate 601, and movable slot plates 605 are respectively provided on one side of the two movable blocks 602. Multiple movable grippers 606 are respectively disposed inside the corresponding movable slot plate 605 and fixed slot plate 604; Two clamping telescopic rods 603 are arranged opposite each other on the other side of the clamping slot plate 601, and the telescopic rods of the two clamping telescopic rods 603 are respectively fixedly connected to the corresponding movable blocks 602.

[0031] Specifically, when performing ultrasonic testing on the bonding strength of the porcelain insulator body 7, one of the porcelain insulator bodies 7 is first placed on one side of one of the fixed slot plates 604. At this time, one side of the porcelain body of the porcelain insulator body 7 is in contact with multiple movable grippers 606 on the fixed slot plate 604. Then, by activating one of the clamping telescopic rods 603, one of the movable blocks 602 moves the movable slot plate 605 on it toward one of the fixed slot plates 604 until multiple movable grippers 606 on the movable slot plate 605 contact the other side of the porcelain body of the porcelain insulator body 7. The movable gripper 606 on the movable slot plate 605 and the multiple movable grippers 606 on the fixed slot plate 604 merge and contact each other, thereby tightly clamping and fixing the porcelain insulator body 7. Due to the mobility of the multiple movable grippers 606 on the corresponding movable slot plate 605 and fixed slot plate 604, it is suitable for clamping porcelain insulator bodies 7 of different lengths. After one porcelain insulator body 7 is fixed, the other porcelain insulator body 7 can be fixed by repeating the previous work through another fixed slot plate 604, another movable slot plate 605 and another clamping telescopic rod 603.

[0032] In specific application scenarios, since the positions of multiple movable grippers 606 on the movable slot plate 605 and the fixed slot plate 604 can be flexibly adjusted, and the movable slot plate 605 can be moved in conjunction with the clamping telescopic rod 603, it can adapt to the clamping requirements of porcelain insulator bodies 7 of different lengths, greatly improving the versatility and adaptability of the clamp and ensuring a secure fixation.

[0033] Reference Figure 1 and Figure 2 In a preferred embodiment, it also includes: The switching motor 12 is located on the lower side of the base 4, and the drive end of the switching motor 12 is connected to one end of the switching shaft 11 via a coupling. The drive motor 8 is mounted on the U-shaped frame 3, and the drive end of the drive motor 8 is connected to one end of the double-acting lead screw 9 via a coupling.

[0034] Working principle: When performing ultrasonic testing on the bonding strength of the porcelain insulator body 7, one of the porcelain insulator bodies 7 is first placed on one side of one of the fixed slot plates 604. At this time, one side of the porcelain body of the porcelain insulator body 7 contacts multiple movable grippers 606 on the fixed slot plate 604. Then, by activating one of the clamping telescopic rods 603, one of the movable blocks 602 moves the movable slot plate 605 on it toward one of the fixed slot plates 604 until multiple movable grippers 606 on the movable slot plate 605 contact the other side of the porcelain body of the porcelain insulator body 7. At this time, multiple movable grippers 606 on the movable slot plate 605 contact the other side of the porcelain body of the porcelain insulator body 7. The movable gripper 606 on the movable slot plate 605 and the multiple movable grippers 606 on the fixed slot plate 604 merge and contact each other, thereby tightly clamping and fixing the porcelain insulator body 7. Due to the mobility of the multiple movable grippers 606 on the corresponding movable slot plate 605 and fixed slot plate 604, it is suitable for clamping porcelain insulator bodies 7 of different lengths. After one porcelain insulator body 7 is fixed, the other porcelain insulator body 7 can be fixed by repeating the previous work through another fixed slot plate 604, another movable slot plate 605 and another clamping telescopic rod 603. After the two porcelain insulator bodies 7 are fixed, the drive motor 8 is turned on to drive the bidirectional lead screw 9 to rotate, thereby bringing the two moving plates 10 closer together. During this process, the two semi-circular dust-proof chambers 501 move closer together and merge into a complete and sealed annular dust-proof chamber, and multiple semi-circular toothed rings 502 merge into two complete circular toothed rings. At this time, the detection position of the porcelain insulator adhesive interface is located inside the annular dust-proof chamber and is completely isolated from the outside. Subsequently, the two moving motors 13 are turned on to drive the two rotating shafts 507 to rotate the corresponding moving gears 506. Since the two moving gears 506 mesh with the corresponding semi-circular toothed rings 502, the two moving gears 506 can drive the moving block 503 along the inside of the complete and sealed annular dust-proof chamber. The entire moving groove of the device moves around the adhesive interface of the porcelain insulator. Multiple moving wheels 504 greatly reduce the resistance during the movement of the moving block 503. When detecting the adhesive interface of the porcelain insulator, the moving block 503 first moves the oil brush body 518 to the starting point of the detection position. Then, by activating two oil pumps 524, the oil inside the compressed oil cylinder 509 is delivered through two oil pipes 526 to the inside of two oil equalization cylinders 525. With the buffer of the two oil equalization cylinders 525, the oil evenly wets the oil brush body 518. Then, driven by the moving block 503, the oil brush body 518 evenly coats the detection position from the starting point to the ending point with oil. After oiling is completed, the extension of the electric telescopic rod 516 allows the ultrasonic probe to... The ultrasonic detector 512 moves closer to the detection position until it contacts the position. With the coupling oil acting as a medium, the ultrasonic detector 512 detects the bonding strength of the porcelain insulator's adhesive interface. As the ultrasonic detector 512 approaches the detection position, the setting block 520 moves and pulls the two connecting ropes 519. Since the two lifting plates 514 are connected to the setting block 520 via their respective connecting ropes 519, when the ropes 519 are pulled, the two lifting plates 514 overcome the elastic force of their corresponding extension springs 515 and rise along their corresponding slide rails 510. This moves the oil brush body 518 and the scraper plate 523 away from the detection position, preventing them from interfering with the ultrasonic detector 512's detection operation. After the detection at this location is completed, the ultrasonic detector 512 is moved away from the detection location by the retraction of the electric telescopic rod 516. Simultaneously, when the two lifting plates 514 lack the tension of the corresponding connecting ropes 519, the two telescopic springs 515 push the oil brush body 518 and the oil scraper plate 523 back into contact with the end and start points of the detection location. When applying oil to the next detection area, the moving block 503 drives the oil brush body 518 to move and apply oil to the next detection area. As the oil scraper plate 523 moves through the previous detection area, it scrapes away any residual oil on its surface. At the same time, by activating the two oil pumps 529, the residual oil adhering to the surface of the oil scraper plate 523 enters the interior of the oil scraper plate 523 through the holes.The oil is then transported through two extraction pipes 528 and finally enters the recovery oil cylinder 513 for recovery, thus cleaning and collecting the residual engine oil after testing without interrupting the testing process.
