Description

Technical Field

[0001] The invention relates to the technical field of pot-type insulator detection, in particular to an automatic pot-type insulator infrared thermal imaging detection device and method. Background Art

[0002] In recent years, with the widespread application of gas insulated switchgear (GIS) in power systems, the stability and reliability of basin insulators as one of the key components are crucial to the safety of power grids. However, due to frequent accidents such as flashover, breakdown and explosion, these failures are mostly caused by tiny defects inside the insulators and aging problems after long-term operation. Under long-term energized conditions, these defects will gradually expand and eventually lead to serious discharge phenomena.

[0003] At present, the detection methods of pot insulators mainly include two categories: electrical and non-electrical. Although electrical detection methods such as pulse current method and ultra-high frequency method can quantitatively detect partial discharge, the former is susceptible to electromagnetic interference, and the latter requires high skills of operators and is difficult to find microcracks. Non-electrical methods such as ultrasonic detection and X-ray imaging technology also have certain limitations and cannot meet the needs of efficient and accurate detection. In contrast, infrared thermal imaging technology has the advantages of non-contact, rapid response and intuitive image display, which is suitable for rapid detection of large-area components. However, there is currently no perfect automated infrared thermal imaging detection device. Manual operation is not only time-consuming, but also very complicated to adjust the position and angle of the device when facing insulators of different sizes and shapes. Especially when large insulators need to be detected on both sides, manual operation is inefficient, the consistency of detection results is poor, and product re-inspection and analysis are difficult, which makes it difficult to meet the needs of daily detection of power grid insulators.

[0004] Therefore, developing an efficient automatic infrared thermal imaging detection device for pot-type insulators that can improve detection efficiency and consistency of results is a technical problem that needs to be solved urgently. Summary of the invention

[0005] In view of the above problems or problems existing in the prior art, the present invention is proposed.

[0006] Therefore, the purpose of the present invention is to provide an automated infrared thermal imaging detection device for pot-type insulators, which can solve the problems of low infrared detection efficiency of pot-type insulators, poor consistency of detection results, difficulty in product re-inspection and analysis, cumbersome operation, and difficulty in fitting the angle to the uneven surface of the pot-type insulator under manual operation.

[0037] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0038] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0039] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments.

[0040] Example 1, reference Figure 1-2 , which is the first embodiment of the present invention, and provides an automatic infrared thermal imaging detection device for pot-type insulators, including a pot-type insulator 100;

[0041] Testing table 200;

[0042] The detection unit 300 includes a detection head 301, a thermal excitation source 302 disposed inside the detection head 301, and a detector 303 electrically connected to the thermal excitation source 302;

[0043] The clamping unit 400 is used for adaptively performing three-axis rotation thermal excitation on the pot-type insulator 100 .

[0044] Further, the clamping unit 400 includes a first clamping group 401 and a second clamping group 402 disposed on one side of the first clamping group 401;

[0045] The first clamping group 401 is used to clamp the detection head 301 to adjust the position and angle;

[0046] The second clamping group 402 is fixedly connected to the center of the testing platform 200 and is capable of clamping and rotating the pot-type insulator 100 .

[0047] Furthermore, the first clamping group 401 includes a fixing seat 401a fixedly mounted on the end of the testing platform 200, a mechanical arm 401b disposed on the top of the fixing seat 401a, and a mounting end 401c disposed on the end of the mechanical arm 401b.

[0048] It should be noted that the device performs infrared thermal imaging detection on the pot-type insulator 100 to determine whether there are defects. Figure 1 As shown, its surface is uneven. If infrared thermal imaging is directly used to detect the pot-type insulator 100, it is difficult to achieve the purpose of uniform detection and the detection results are difficult to achieve consistency. However, under the adjustment of the clamping unit 400, the device can be well fitted on the uneven surface of the pot-type insulator 100, which can improve the uniformity of thermal excitation and increase the effective signal collection area of ​​the detector, which is more accurate and convenient than manual operation.

[0049] Preferably, the testing platform 200 is a rectangular table with supporting legs, on which the testing unit 300 and the clamping unit 400 are fixed. Four sets of supporting legs with adjustable heights are installed at the bottom of the testing platform 200, which can keep the testing platform 200 in a horizontal state, facilitate maintaining the testing unit 300 and the clamping unit 400 on the same horizontal plane, and improve the accuracy of the test results.

[0050] Preferably, the detection unit 300 is composed of a detection head 301 fixedly mounted at the end of the mounting end 401c, a thermal excitation source 302 arranged on the inner side of the detection head 301, and a detector 303 electrically connected to the thermal excitation source 302. Specifically, the detection head 301 is designed as a rectangular parallelepiped structure with a hollow interior, which can effectively accommodate and protect the thermal excitation source 302 and the detector 303. This design not only provides a stable installation platform, but also concentrates the infrared heat waves released by the thermal excitation source 302 onto the surface of the pot-type insulator 100 through efficient thermal wave convergence, thereby enhancing the sensitivity of the detector 303 to temperature changes and improving the accuracy and resolution of the detection results. The closed structure of the detection head 301 helps to maintain the stability of the internal environment, reduce the influence of external factors such as wind speed and temperature fluctuations on the thermal excitation and detection process, and improve the consistency and reliability of the detection results. The thermal excitation source 302 and the detector 303 are prior art. The thermal excitation source 302 releases infrared heat waves to hit the surface of the pot-type insulator 100, and then uses the infrared imaging function of the detector 303 to determine whether the pot-type insulator 100 has defects.

[0051] Better, such as Figure 2 As shown, a set of fixing seats 401a are fixedly welded at the side of the testing platform 200, a set of mechanical arms 401b are fixedly connected to the fixing seats 401a, and a mounting end 401c at the end of the mechanical arms 401b is used to mount the testing platform 200. The mechanical arm 401b can adjust the position of the mounting end 401c, and by adjusting the angle and position of the mounting end 401c, the thermal excitation source 302 and the detector 303 thereof can be attached to the uneven surface of the pot-type insulator 100.

[0052] Preferably, the mechanical arm 401c is a three-axis mechanical arm that can be adjusted in three-dimensional space. First, the three-axis mechanical arm 401b can achieve precise positioning in three-dimensional space, ensuring that the thermal excitation source 302 and the detector 303 are always in the best working position. By flexibly adjusting the angle and position of the mounting end 401c, the mechanical arm 401b can adapt to pot-type insulators of different shapes and sizes, thereby improving the coverage and accuracy of the detection. In addition, the high-precision adjustment capability of the mechanical arm 401b helps to keep the distance between the thermal excitation source 302 and the detector 303 and the surface of the insulator constant, ensuring uniform thermal excitation and consistency of the detection signal, thereby improving the reliability and repeatability of the detection results. Secondly, the automatic adjustment function of the mechanical arm 401b greatly reduces the need for manual intervention and significantly improves the detection efficiency. The operator only needs to set parameters through the control system to automatically complete complex positioning and adjustment tasks, reducing the possibility of human error. This not only saves a lot of human resources, but also shortens the time required for each detection, making large-scale, high-frequency detection more feasible.

[0053] In summary, by adjusting the position and angle of the thermal excitation source 302 and the detector 303 by the first clamping group 401, the observation angle of the detection head 301 can fit the uneven surface of the basin insulator 100, thereby improving the uniformity of thermal excitation and increasing the effective signal collection area of ​​the detector, which is more accurate and convenient than manual operation.

[0054] Example 2, reference Figure 3 to Figure 5 , which is the second embodiment of the present invention, and is different from the first embodiment in that it includes a second clamping group 402 including a vertical rotating member 402a fixedly arranged at the center of the detection platform 200, a bidirectional linear rail 402b arranged on the top of the vertical rotating member 402a, two groups of supporting columns 402c arranged on the bidirectional linear rail 402b, and a clamping member 402d arranged on the supporting column 402c.

[0055] Furthermore, the two groups of support columns 402c are symmetrically arranged on the bidirectional linear track 402b, and the bidirectional linear track 402b is equipped with a motor M to drive the two groups of support columns 402c to move relative to each other.

[0056] Furthermore, the support column 402c is slidably connected to the bidirectional linear rail 402b via a moving seat N; the support column 402c is a ladder column that is narrow at the top and wide at the bottom, and an arc groove 402c-1 is provided through the end thereof.

[0057] Furthermore, the clamping member 402d includes a horizontal flip axis 402d-1 installed on the inner side of the arc groove 402c-1 and a clamping claw 402d-2 arranged on the inner side of the horizontal flip axis 402d-1.

[0058] Furthermore, the clamping jaw 402d-2 is fixed to the front end of the horizontal flip shaft 402d-1;

[0059] The horizontal flip axis 402d-1 is vertically embedded in the arc groove 402c-1.

[0060] Furthermore, the clamping jaw 402d-2 is C-shaped, and a fixing hole Q is provided through the upper and lower surfaces thereof;

[0061] The fixing hole Q can be fixedly connected to the flange hole on the surface of the pot body of the pot type insulator 100 .

[0062] It should be noted that the second clamping group 402 is fixedly connected to the center of the test bench 200 and can clamp and rotate the pot insulator 100. Among them, the vertical rotating member 402a is installed on the end face of the test bench 200. The vertical rotating member 402a is a prior art and can achieve relative rotation relative to the table surface of the test bench 200. A set of bidirectional linear rails 402b is fixedly connected to the axis of the vertical rotating member 402a. The bidirectional linear rails 402b are also prior art and can drive the support columns 402c at the end to perform relative movement, synchronously converge or move away.

[0063] Preferably, the vertical rotating member 402a may be a rotating turntable. Under manual or electric drive, the bidirectional linear rail 402b is driven to rotate in the vertical direction. The bidirectional linear rail 402b may be a linear screw assembly, which may be driven by the motor M to drive the support column 402c to move relative to each other.

[0064] Preferably, the movable seat N is threadedly connected to the supporting column 402c, and the movable seat N is a sliding bearing, which can move relative to the bidirectional linear rail 402b so as to clamp pot insulators 100 of different sizes.

[0065] Preferably, the support column 402c is a trapezoidal block that is narrow at the top and wide at the bottom, and its wider ground is fixedly connected to the movable seat N to increase its stability. The narrower shape at the top of the support column 402c facilitates the turning of the pot-type insulator 100 during inspection.

[0066] Preferably, arc grooves 402c-1 are formed through the end portions of the two groups of supporting columns 402c, and the arc grooves 402c-1 are U-shaped grooves for easy installation / disassembly of the clamping member 402d.

[0067] Preferably, the clamping member 402d is composed of a horizontal flip shaft 402d-1 and a clamping claw 402d-2 fixedly mounted at the front end of the horizontal flip shaft 402d-1. The horizontal flip shaft 402d-1 can rotate relative to the arc groove 402c-1, thereby flipping and adjusting the angle of the pot insulator 100 clamped in the clamping claw 402d-2.

[0068] Preferably, the horizontal flip shaft 402d-1 can be a supporting round rod, and a half-circle gear mark is provided on the arc surface of the arc groove 402c-1, which matches the gear mark provided on the horizontal flip shaft 402d-1, so that the horizontal flip shaft 402d-1 can be lifted and flipped, and then placed on the arc groove 402c-1 for angle limiting.

[0069] Preferably, the clamp 402d-2 is C-shaped, and fixing holes Q are provided on both the upper and lower surfaces thereof. The inner cavity of the clamp 402d-2 is rectangular, and can fit tightly on the side of the pot-type insulator 100. The fixing holes Q provided on the clamping surface of the clamp 402d-2 can be connected to the flange holes of the pot-type insulator 100 by bolts, thereby adapting to the detection of pot-type insulators 100 of various sizes.

[0070] The other results are the same as those in Example 1.

[0071] When in use, firstly, two sets of clamping jaws 402d-2 are connected to the flange holes on both sides of the pot-type insulator 100 by bolts to ensure that the clamping jaws are firmly fixed and can stably support the insulator. Next, the motor M controls the bidirectional linear rail 402b to drive the moving seat N and the supporting column 402c to limit the clamping jaws 402d-2 to ensure the stability of the insulator during the detection process.

[0072] The vertical rotating member 402a at the end of the testing platform 200 can adjust the vertical position of the pot-type insulator 100, so that it can be accurately tested at different heights. At the same time, the horizontal flip axis 402d-1 can adjust the horizontal rotation position of the pot-type insulator 100, so that the insulator can be tested at multiple angles as needed, thereby achieving full coverage.

[0073] This device can freely adjust the position and angle of the sample and the detection head, and adapt to pot-type insulators of different sizes and appearances. It is more accurate, convenient and stable than manual adjustment. The motion setting parameters are recorded, and the same operation can be repeated when the same model sample is repeatedly tested, which greatly improves the consistency of the test results and reduces the difficulty of defect re-inspection. In this way, the efficiency of infrared thermal imaging detection of pot-type insulator defects can be greatly improved.

[0074] In summary, under the setting of the adaptive three-axis fixed detection device, the mobile seat N and the support column 402c can fine-tune the clamping claw 402d-2 through the precise control of the motor M and the bidirectional linear rail 402b, so as to ensure the accurate position of the pot-type insulator 100 during the detection process. This not only improves the accuracy of the detection results, but also reduces human errors and achieves high-precision positioning. The combined use of the vertical rotating member 402a and the horizontal flip axis 402d-1 allows the pot-type insulator 100 to rotate and tilt freely in multiple dimensions, so that it can be fully and multi-angled. This flexibility is particularly suitable for insulators with complex shapes and uneven surfaces, ensuring that each part can be fully thermally stimulated and data collected.

[0075] Embodiment 3 is the third embodiment of the present invention, which is different from the first two embodiments in that it also includes an automatic infrared thermal imaging detection method for pot-type insulators, specifically:

[0076] Use the clamp to pass through the flange hole on the edge of the basin insulator and fix it to ensure the sample is stable;

[0077] The distance between the clamping arms can be adjusted through the vertical rotating parts, bidirectional linear rails and supporting columns to adapt to insulator samples of different sizes;

[0078] The horizontal turning axis is used to realize the horizontal rotation of the pot insulator so as to carry out double-sided inspection;

[0079] The vertical rotating part at the bottom can drive the entire device and the sample to rotate vertically to achieve precise angle positioning;

[0080] The mechanical arm is used to clamp the detection head and fine-tune its position and angle to make it fit the uneven surface of the insulator;

[0081] The thermal excitation source inside the detection head applies active infrared thermal excitation to the sample;

[0082] The detector collects the temperature change field data of the sample surface caused by thermal radiation and heat conduction.

[0083] It should be noted that the clamp is passed through the flange hole on the edge of the pot insulator and fixed to ensure that the sample is stable during the entire detection process. The distance between the clamping arms is adjusted by the vertical rotating part, the bidirectional linear rail and the supporting column to adapt to insulator samples of different sizes, ensuring the versatility and flexibility of the system. The horizontal flip axis is used to achieve horizontal rotation of the pot insulator for double-sided detection to ensure that each surface can be fully inspected by thermal imaging. The bottom vertical rotating part can drive the entire device and the sample to rotate vertically to achieve precise angular positioning, ensuring that the detection head can fully scan the insulator at different heights and angles. The robotic arm is used to clamp the detection head and fine-tune its position and angle to make it fit the uneven surface of the insulator tightly, ensuring that the thermal excitation source 302 and the detector 303 maintain the best working distance and angle with the insulator surface. The thermal excitation source inside the detection head applies active infrared thermal excitation to the sample, causing the surface temperature of the insulator to change. The detector collects the sample surface temperature change field data caused by thermal radiation and heat conduction. After numerical processing and model calculation, an intuitive thermal imaging image is generated to reveal the defects, cracks and coating thickness inside the insulator. This comprehensive design not only improves the accuracy and consistency of detection, but also significantly improves the detection efficiency and reliability of the results.

[0084] It is important to note that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
