[0045] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0047] In the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them.

A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0048] In the description of this embodiment, the terms "upper", "lower", "right", etc., directions or positional relationships are based on the directions or positional relationships shown in the drawings, and are only for the convenience of description and simplification of operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0049] This embodiment provides a flaw detection device, such as Figure 1-Figure 6 As shown, it is used to perform flaw detection on insulators (not shown in the figure), and the flaw detection device includes an equipment ring 1, a conveying mechanism 2, a detection mechanism 3 and a feedback mechanism 4. The equipment ring 1 includes a support frame 11 and a rotating ring 12, and the rotating ring 12 is rotatably arranged on the support frame 11; the conveying mechanism 2 includes a conveyor belt 21, and the conveyor belt 21 is configured to drive the insulator to pass through the rotating ring 12. Along the conveying direction of the conveyor belt 21, the conveyor belt 21 is spaced apart with a plurality of accommodating grooves 211, and the accommodating grooves 211 are used to accommodate and position the insulators; the detection mechanism 3 is connected to the rotating ring 12, and the detection mechanism 3 can perform flaw detection on the insulator and mark the damaged insulator; the feedback mechanism 4 is connected to the rotating ring 12 and is spaced apart from the detection mechanism 3, and the feedback mechanism 4 can identify the marked insulator.

[0050] The receiving groove 211 of the conveyor belt 21 in the device can adapt to the insulator, so that it can be stably carried during transmission and pass through the rotating ring 12 in an orderly manner, ensuring the stable position of the insulator during flaw detection. This effectively avoids marking deviations caused by unstable positions, prevents mislabeling of normal insulators, and improves marking accuracy. At the same time, the stable position greatly reduces flaw detection errors, makes data accurate and reliable, promotes accurate flaw detection, and also facilitates batch processing, improves overall flaw detection efficiency, enhances accuracy and reliability, meets the flaw detection needs of mass production, and improves the quality and stability of flaw detection operations.

[0051] In this embodiment, if Figure 5As shown, the detection mechanism 3 includes a first bracket assembly 31, a detector 32 and a spray gun 33. One end of the first bracket assembly 31 is connected to the inner wall of the rotating ring 12, and the detector 32 and the spray gun 33 are arranged at the other end of the first bracket assembly 31. The detector 32 can detect flaws in the insulator, and the spray gun 33 can mark the damaged insulator. The detector 32 is used to detect internal damage of the insulator. Since it detects the internal condition, if inkjet marking is not performed, it is difficult to distinguish whether the insulator is intact only by appearance after the detection is completed. The detection mechanism 3 is connected to the rotating ring 12. When the insulator is transmitted, it can not only detect flaws using the detector 32, but also mark the damaged insulator through the spray gun 33, so that the flaw detection results can be presented in a timely and intuitive manner, thereby avoiding the confusion of subsequent classification and collection.

[0052] In this embodiment, the detector 32 uses an ultrasonic flaw detector, which detects internal damage by using changes in reflection, refraction and other characteristics of ultrasonic waves when propagating inside the insulator. In other embodiments, the detector 32 may also use a radiographic flaw detector, which uses radiation to penetrate the insulator and forms an image based on the difference in the degree of radiation absorption by different internal structures.

[0053] In this embodiment, if Figure 5 As shown, the spray gun 33 includes an ink bottle 331, and the ink bottle 331 supplies ink for the spray gun 33. When a damaged insulator is detected, the spray gun 33 can take ink from the ink bottle 331 according to instructions and spray it accurately at a specific location. Because the ink bottle 331 has a storage capacity of ink, the spray gun 33 does not need to frequently refill ink, and can continuously and efficiently mark multiple damaged insulators, thereby improving the efficiency and accuracy of the flaw detection process.

[0054] In this embodiment, if Figure 5 As shown, the first bracket assembly 31 includes a telescopic rod 314, and the detector 32 and the spray gun 33 are arranged at one end of the telescopic rod 314 close to the insulator. The telescopic rod 314 is used to adjust the distance between the detector 32 and the spray gun 33 and the insulator. Before the flaw detection operation begins, the two can be adjusted to the most suitable distance according to the size specifications, shape characteristics and accuracy requirements of the insulator. For insulators with larger sizes or special shapes, appropriately increasing the distance can ensure that the detector 32 can fully scan its internal structure and the spray gun 33 can also mark at the appropriate position; and for situations with higher accuracy requirements, shortening the distance can enable the detector 32 to obtain more accurate internal damage information, and the marking of the spray gun 33 is also more detailed and accurate.

[0055] Specifically, Figure 5As shown, the first bracket assembly 31 also includes a first mounting seat 311, a first fastener 312, a first clamping member 313, a first fixing frame 315 and a second fixing frame 316. The first fastener 312 penetrates the first mounting seat 311 and the rotating ring 12 to fix the first mounting seat 311 on the inner wall of the rotating ring 12. The first mounting seat 311 is provided with a first clamping groove 3111 at one end away from the rotating ring 12. One end of the first clamping member 313 is clamped and matched with the first clamping groove 3111. The other end of the first clamping member 313 is plugged and matched with the telescopic rod 314. The telescopic rod 314 is connected to the detector 32 through the first fixing frame 315, and the telescopic rod 314 is connected to the spray gun 33 through the second fixing frame 316. The various parts of the first bracket assembly 31 are detachably connected, which is convenient for rapid replacement when a component fails, reduces maintenance time cost and improves availability, and is also conducive to disassembly during transportation and storage to reduce space occupation, ensuring stable and efficient flaw detection operations.

[0056] In this embodiment, if Figure 6 As shown, the feedback mechanism 4 includes a second bracket assembly 41 and a rangefinder 42. One end of the second bracket assembly 41 is connected to the rotating ring 12, and the rangefinder 42 is connected to the other end of the second bracket assembly 41. The rangefinder 42 is used to identify the marked insulator. The second bracket assembly 41 provides support and positioning for the rangefinder 42. After the spray gun 33 marks the insulator, the rangefinder 42 can capture the marking signal to determine its position during transmission, avoid manual recognition errors, and improve the efficiency and accuracy of flaw detection and subsequent processing processes.

[0057] Specifically, the rangefinder 42 is an infrared rangefinder. When the ink coating is not sprayed on the surface of the insulator, the distance data measured by the infrared rangefinder is in a normal range. Once the ink coating is sprayed on the surface of the insulator by the spray gun 33, its thickness increases, causing the distance detected by the infrared rangefinder to become smaller accordingly. Through this change in distance data, the marked insulator can be accurately identified, providing a reliable basis for subsequent classification and processing operations. In other embodiments, other types of rangefinders 42 may also be selected, such as laser rangefinders, ultrasonic rangefinders, etc., which are not specifically limited here.

[0058] In this embodiment, if Figure 6 As shown, the feedback mechanism 4 also includes an alarm component 43, which is arranged at one end of the second bracket component 41 away from the rotating ring 12. The alarm component 43 includes a buzzer 431 and a warning light 432. The buzzer 431 is used to generate an audio signal, and the warning light 432 is used to present light signals of different colors. When the rangefinder 42 recognizes the marked insulator, the alarm component 43 is activated. The buzzer 431 sounds to attract attention, and the warning light 432 changes color to distinguish. The sound and light work together to help the staff to detect in time and accurately, and reduce classification errors.

[0059] Optionally, the alarm component 43 only includes a buzzer 431 to emit an audio signal. When the rangefinder 42 identifies the marked insulator, the buzzer 431 is activated, which can effectively attract the auditory attention of the staff, and is low in cost and easy to implement. Optionally, the alarm component 43 only includes a warning light 432. After the rangefinder 42 identifies the marked insulator, the warning light 432 is activated, which is suitable for quiet scenes or scenes where visual attention is easy to concentrate, reducing costs and energy consumption, and enhancing practicality and adaptability.

[0060] In this embodiment, if Figure 6 As shown, the second bracket assembly 41 includes a second mounting seat 411 and a mounting frame 414, one end of the second mounting seat 411 is connected to the inner wall of the rotating ring 12, the rangefinder 42 and the mounting frame 414 are connected to the other end of the second mounting seat 411, and the mounting frame 414 is installed with an alarm assembly 43. The second mounting seat 411 and the mounting frame 414 ensure that the positions of the rangefinder 42 and the alarm assembly 43 are relatively fixed during the operation of the equipment.

[0061] Specifically, Figure 6 As shown, the second bracket assembly 41 also includes a second fastener 412, a second clamping member 413 and a connecting rod 415. The second fastener 412 penetrates the second mounting seat 411 and the rotating ring 12 to fix the second mounting seat 411 to the inner wall of the rotating ring 12. The second mounting seat 411 is provided with a second mounting groove 4111 and a second clamping groove 4112 at one end away from the rotating ring 12. One end of the second clamping member 413 is clamped and matched with the second clamping groove 4112, and the other end of the second clamping member 413 is plugged and matched with the rangefinder 42. The connecting rod 415 penetrates the mounting frame 414, and its two ends are connected to the groove wall of the second mounting groove 4111. The second bracket assembly 41 ensures the stable operation of the rangefinder 42 and the alarm assembly 43, and improves the flaw detection efficiency and equipment reliability.

[0062] In this embodiment, if Figure 4 As shown, first mounting grooves 121 are respectively provided at both ends of the rotating ring 12 for mounting the detection mechanism 3 and the feedback mechanism 4 . The first mounting grooves 121 provide mounting positions for the detection mechanism 3 and the feedback mechanism 4 .

[0063] In this embodiment, if Figure 1 and Figure 3 As shown, the flaw detection device is provided with a set of detection mechanism 3 and feedback mechanism 4. In other embodiments, multiple sets of detection mechanism 3 and feedback mechanism 4 can be provided according to the detection frequency of the detection mechanism 3, the transmission speed of the transmission belt 21 and the rotation speed of the rotating ring 12, and the number of settings is not limited here. When multiple sets of detection mechanism 3 and feedback mechanism 4 are provided, the detection mechanism 3 and the feedback mechanism 4 are provided at intervals to enhance the coordination between the flaw detection, spraying and feedback work.

[0064] In this embodiment, if Figure 1 and Figure 2 As shown, the conveying mechanism 2 includes a base assembly 22 and two connecting shafts 23. The conveying belt 21 is arranged around the outer periphery of the base assembly 22. The two connecting shafts 23 are respectively arranged at both ends of the base assembly 22 and are rotatably connected to the base assembly 22. One of the two connecting shafts 23 is a driving shaft, which can abut against the conveying belt 21 to drive the conveying belt 21 to operate. The base assembly 22 plays a role in firmly supporting the conveying belt 21, evenly bearing the weight of the conveying belt 21 and the insulator, and avoiding deformation and sagging of the conveying belt 21 due to uneven force, thereby ensuring that the conveying mechanism 2 can smoothly convey the insulator, and improving the continuity and work efficiency of the insulator flaw detection.

[0065] In this embodiment, if Figure 2 As shown, the base assembly 22 includes a first slot plate 221 and a second slot plate 222. The first slot plate 221 is inserted into the rotating ring 12. Two first connecting parts 2211 are arranged at intervals at both ends of the first slot plate 221. Two second connecting parts 2221 are arranged at intervals at both ends of the second slot plate 222. The first connecting part 2211 is detachably connected to the second connecting part 2221 through a connecting shaft 23. With such a design, the base assembly 22 and the rotating ring 12 are closely matched to form a stable frame, which not only stably supports the transmission belt 21 to ensure the smooth transmission of the insulator, but also facilitates equipment assembly, commissioning, maintenance and component replacement due to the detachable connection, improves the efficiency and flexibility of the insulator production or testing process, and ensures smooth and reliable operation of the system.

[0066] Specifically, Figure 2 As shown, between two first connection parts 2211 and two second connection parts 2221, space is provided for the connection shaft 23 to contact with the conveyor belt 21. The two ends of the connection shaft 23 are stepped, and the connection shaft 23 includes a large diameter section and a small diameter section connected to each other, and the small diameter section is adapted to the first connection part 2211 and the second connection part 2221 to achieve rotatable connection therewith. The large diameter section located between the two small diameter sections is connected to the conveyor belt 21, and the outer surface of the large diameter section is flush with or higher than the side surface of the first connection part 2211 and the second connection part 2221. After the conveying mechanism 2 is started, the connection shaft 23 rotates and transmits power to make the conveyor belt 21 operate, so as to realize efficient and smooth conveying of insulators on the conveyor belt 21.

[0067] Furthermore, friction lines are provided on the outer surface of the large diameter section of the connecting shaft 23 and the inner wall surface of the transmission belt 21. This design increases the friction between the two, thereby improving the force transmission effect between the connecting shaft 23 and the transmission belt 21, ensuring the high efficiency and stability of power transmission, and enabling the insulator to operate more stably during the transmission process.

[0068] In this embodiment, if Figure 2As shown, a first guide groove 2212 is provided on the side of the first slot plate 221 away from the second slot plate 222, a second guide groove 2222 is provided on the side of the second slot plate 222 away from the first slot plate 221, and the conveyor belt 21 is arranged in the first guide groove 2212 and the second guide groove 2222. This enables the conveyor belt 21 to stably move along the predetermined guide groove track during operation, effectively preventing it from experiencing unstable phenomena such as lateral deviation or shaking, improving the accuracy and reliability of the operation of the conveyor belt 21, and thus ensuring the stability of the insulator on the conveyor belt 21.

[0069] In this embodiment, the base assembly also includes a support frame (not shown), one end of which is connected to both sides of the first slot plate 221 and the second slot plate 222, and the other end of which is connected to the ground to provide support for the entire conveying mechanism 2.

[0070] In this embodiment, if Figure 3 As shown, the equipment ring 1 includes a power assembly 13, the power assembly 13 includes a driving gear 133, the outer periphery of the rotating ring 12 is provided with a tooth structure, the support frame 11 is annular, the rotating ring 12 is rotatably arranged on the inner periphery of the support frame 11, the support frame 11 is provided with a through hole 113, and the driving gear 133 is meshed with the rotating ring 12 through the through hole 113. With the help of gear transmission, the power transmission is accurate and efficient, and the stability is strong. The annular support frame 11 provides a stable support for the rotating ring 12, ensuring smooth rotation without deviation, compact structure, small footprint, and flexible placement.

[0071] Specifically, the support frame 11 is provided with an inner ring groove 111, and the rotating ring 12 is rotatably arranged in the inner ring groove 111, providing a stable rotating track for it, constraining the direction, preventing deviation and shaking, and allowing the detection mechanism 3 and the feedback mechanism 4 to operate smoothly.

[0072] Specifically, Figure 3 and Figure 4 As shown, the power assembly 13 also includes a power source 131 and a transmission shaft 132. The power source 131 includes a motor 1311 and a motor seat 1312. A fixing portion 112 is provided on the side wall of the support frame 11 near the through hole 113. The motor 1311 is fixedly connected to the fixing portion 112 through the motor seat 1312. The output end of the motor 1311 is connected to the transmission shaft 132. The transmission shaft 132 is penetrated by a driving gear 133 to ensure that the power can be stably and efficiently transmitted from the motor 1311 to the driving gear 133 through the transmission shaft 132. This makes the power transmission process from the motor 1311 to the driving gear 133 efficient and smooth, reduces the loss and fluctuation of energy in the transmission link, and enhances the reliability and durability of the operation of the equipment ring 1.

[0073] In this embodiment, the equipment ring 1 further includes a support 14 , one end of the support 14 is connected to the support frame 11 , and the other end of the support 14 is connected to the ground, providing stable support for the support frame 11 .

[0074] This embodiment also provides a flaw detection method, which uses the above-mentioned flaw detection device to detect flaws on insulators. The flaw detection method includes:

[0075] S1: placing the insulators one by one in the receiving grooves 211 on the conveyor belt 21;

[0076] S2: The rotating ring 12 rotates, and the detection mechanism 3 performs flaw detection on the insulator located inside the rotating ring 12;

[0077] S3: Determine whether the insulator is damaged, if so, execute step S4;

[0078] S4: the detection mechanism 3 marks the damaged insulator;

[0079] S5: The feedback mechanism 4 identifies the marked insulator.

[0080] By placing the insulator on the receiving groove 211 of the conveyor belt 21, the orderliness and stability of the insulator in the conveying link are guaranteed, and the influence of the chaos or displacement during transmission on the accuracy of the flaw detection is avoided. During the flaw detection process, it can be determined whether the insulator is damaged. Once the damage is found, the detection mechanism 3 will mark it immediately, and then the feedback mechanism 4 can identify it. In this way, the smooth process from detection, marking to identification has established an efficient and reliable flaw detection and feedback mechanism, which reduces the probability of misjudgment and missed detection, ensures that the damaged insulator can be identified and located in time, meets the flaw detection needs of mass production, improves the quality and stability of the flaw detection operation, provides a guarantee for the quality control of insulators, and ensures the safety and reliability of insulator-related application scenarios.
