Description

Technical Field

[0001] The present invention belongs to the field of detection technology, and specifically relates to a measuring device characterized by mechanical technology, and more particularly to a detection device and a detection method for a metal flange of a basin-type insulator. Background Art

[0002] The metal flange consists of a shielding ring and a flange body. Since the shielding ring and the flange body are manufactured separately and then assembled, the mechanical vibration during handling before assembly and assembly can easily cause the shielding ring of the metal flange to deform. Therefore, the installed metal flange needs to be tested for multiple parameters. The shielding ring serves as a support for the insulating basin and plays an important role in current shielding. After production, it needs to be surface roughened and silver-plated. The plating strength needs to be tested. However, since the shielding ring needs to be provided with a connecting column for connecting to the flange body, the shielding ring is not a single circular ring, but a special-shaped part with a protruding connecting column. Therefore, traditional testing methods are inconvenient and incomplete.

[0003] Therefore, due to the technical problem that it is difficult to synchronously detect parameters such as the shielding ring curvature, coating strength, and shielding ring connecting column coating strength, it is necessary to design a basin-type insulator metal flange detection device and detection method.

[0004] It should be noted that the above information disclosed in this background technology section is only used to understand the background technology of the present application concept, and therefore, the above description is not considered to constitute information of the prior art.

[0045] Basin insulators are important components in gas-insulated switchgear (GIS). Most of them are made of a composite material composed of AI2O3 particles and epoxy resin, which is cast to form an insulating basin. The insulating basin is then connected to a metal flange to form a basin insulator. The metal flange includes a shielding ring and a flange body. However, the inventors found that since the shielding ring and the flange body are manufactured separately and then assembled, the mechanical vibration before assembly and during assembly can easily cause the metal flange to deform. Therefore, it is necessary to perform multiple parameter tests on the installed metal flange. In addition, the shielding ring serves as a support for the insulating basin and plays an important role in current shielding. After production is completed, it needs to be roughened and silver-plated, and the plating strength needs to be tested. However, since the shielding ring is a ring-shaped special-shaped part, how to ensure full contact with the workpiece is an urgent problem that needs to be solved.

[0046] The defects in the above solutions are the results obtained by the inventors after practice and careful research. Therefore, the discovery process of the above problems and the solutions proposed by the present disclosure in this article should be the contributions made by the inventors to the present disclosure during the disclosure process.

[0047] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0048] The following embodiments of the present invention are described in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features therein may be combined with each other.

[0049] like Figure 1 and Figure 2As shown, at least one disclosed embodiment provides a pot-type insulator metal flange detection device, comprising: a first detection mechanism 1 and a second detection mechanism 2 of the same structure, wherein a shielding ring 31 of a metal flange 3 passes through the first detection mechanism 1 and the second detection mechanism 2, and the first detection mechanism 1 and the second detection mechanism 2 move in opposite directions along the shielding ring 31 to simultaneously detect the curvature of the shielding ring 31 and the strength of the surface coating of the shielding ring 31; wherein the first detection mechanism 1 comprises: two clamping plates 11 stacked up and down; between the two clamping plates 11 An arc-shaped through hole 111 is formed through which the shielding ring 31 passes. One end of the through hole 111 is circular, and an arc-shaped notch 112 is provided at the other end so that the edge of the through hole 111 is in complete contact with the outer wall of the shielding ring 31; the two clamps 11 move synchronously along the shielding ring 31 to scrape the coating through the edge of the through hole 111. If the coating strength is unqualified, debris will be scraped off. If the curvature of the shielding ring 31 is unqualified, the clamps 11 will be blocked and unable to move along the shielding ring 31, thereby realizing simultaneous detection of the curvature and coating strength of the shielding ring 31.

[0050] In this embodiment, the arc-shaped through hole 111 can adapt to the curvature of the shielding ring 31 , so that the first detection mechanism 1 and the second detection mechanism 2 can move in opposite directions along the shielding ring 31 .

[0051] Specifically, Figure 2 The position indicated by the dashed line is the arc-shaped notch 112. The through hole 111 is configured as an arc so that it can fully cover the outer wall of the shielding ring. In addition, as an optional embodiment, the air channel 122 is close to the arc-shaped notch 112 and is located on the rear side of the arc-shaped notch's movement direction. When the through hole 111 slides past a certain position of the shielding ring, the air channel 122 moves to that position. At this time, if the coating strength is not up to standard, the sliding of the arc-shaped notch 112 will cause the coating to loosen, and then the air channel will suck in the debris. To ensure the comprehensiveness of the debris collection, the debris can also be collected manually at the same time. That is, the debris that cannot be sucked in or that falls is large will be collected by manual re-inspection.

[0052] In this embodiment, when inspecting the shielding ring 31 , the first inspection mechanism 1 and the second inspection mechanism 2 gradually approach each other, and when moving to the connecting column 33 , the first inspection mechanism 1 and the second inspection mechanism 2 contact each other, and the cross-section of the two slide grooves 113 after contact is circular.

[0053] In this embodiment, the clamping plates 11 and the connecting plates 13 are detachable, so that the shielding ring 31 can pass through the through hole 111 after the two clamping plates 11 are respectively installed on the connecting plates 13 .

[0054] In this embodiment, the upper and lower clamping plates 11 are attached together.

[0055] In this embodiment, the edge of the through hole 111 can contact the outer wall of the shielding ring 31, and the coating of the shielding ring 31 can be scraped by the edge. If debris can be scraped off, it is determined that the coating strength is unqualified.

[0056] like Figure 3 and Figure 4 As shown, in an optional embodiment, a sliding groove 113 is opened on the side walls of the two splints 11 along the length direction of the splint 11, and the sliding groove 113 is connected to the arc-shaped notch 112, and the cross-section of the sliding groove 113 is semicircular; a guide groove 114 is opened on the inner wall of the sliding groove 113 along the length direction of the sliding groove 113; a curved plate 12 is slidably arranged in the sliding groove 113, and the curved plate 12 is adapted to the sliding groove 113, and the outer wall of the curved plate 12 is in contact with the inner wall of the sliding groove 113; a slider 121 is provided on the curved plate 12 to adapt to the guide groove 114 and be inserted into the guide groove 114; the edge of one side of the curved plate 12 close to the arc-shaped notch 112 is adapted to the edge of the arc-shaped notch 112;

[0057] When the first detection mechanism 1 and the second detection mechanism 2 move to the connecting column 33 on the shielding ring 31, the corresponding clamping plates 11 on the first detection mechanism 1 and the second detection mechanism 2 contact, and the two arc-shaped plates 12 wrap the connecting column 33. The two arc-shaped plates 12 move synchronously toward the arc-shaped notch 112, and the connecting column 33 is scraped by the arc-shaped plates 12. If debris falls from the connecting column 33 when the arc-shaped plates 12 move, it is judged that the surface coating of the connecting column 33 is unqualified.

[0058] In this embodiment, when the first detection mechanism 1 and the second detection mechanism 2 move to the connecting column 33, the side walls of the two arc plates 12 contact each other. At this time, the two arc plates 12 just wrap the connecting column 33, and the side of the arc plate 12 away from the through hole 111 is flush with the side where the connecting column 33 and the flange body 32 are connected. At this time, the moving arc plate 12 can perform a complete inspection of the coating coated on the connecting column 33; the side of the arc plate 12 in contact with the connecting column 33 can be a friction surface.

[0059] In this embodiment, the cooperation between the slider 121 and the guide groove 114 can prevent the arc plate 12 from falling and prevent the arc plate 12 from rotating when moving, so that the arc plate 12 can be accurately aligned with the edge of the arc notch 112.

[0060] In this embodiment, only the portion of the connecting column 33 close to the shielding ring 31 is coated with a coating. When there is a certain space between the side of the arc plate 12 away from the through hole 111 and the side where the connecting column 33 and the flange body 32 are connected, the edge of the other side of the arc plate 12 is farther away from the shielding ring 31 than the coating on the connecting column 33, so that when the arc plate 12 moves toward the arc notch 112, the coating area on the connecting column 33 can be completely scraped for detection.

[0061] In this embodiment, one side of the arc plate 12 close to the arc notch 112 is adapted to the arc notch 112, so that the arc plate 12 can fit with the edge of the arc notch 112 after movement, completing the complete detection of the connecting column 33. At this time, the moving path of the arc plate 12 covers the outer wall of the shielding ring 31 at the connection position between the shielding ring 31 and the connecting column 33, completing the strength detection of the coating at all positions of the shielding ring 31 and the outer wall of the connecting column 33.

[0062] In this embodiment, when the curvature of the shielding ring 31 is unqualified, the movement of the clamping plate 11 is hindered and the clamping plate 11 cannot move. At this time, it is determined that the curvature of the shielding ring 31 is unqualified.

[0063] In this embodiment, if the arc-shaped plate 12 cannot move to contact the arc-shaped notch 112 , it is determined that the size of the connecting post 33 or the connection position between the connecting post 33 and the shielding ring 31 is unqualified.

[0064] In an optional embodiment, an air duct 122 is provided on the splint 11, and one end of the air duct 122 is located in the through hole 111; the air duct 122 is connected to an air source, and the air source is electrically connected to a control module, and the control module controls the air source to pump air out of the air duct 122 to collect fallen debris through the air duct 122, and to move the arc plate 12 toward the arc notch 112.

[0065] In this embodiment, there may be a gap between the inner wall of the through hole 111 and the shielding ring 31. The debris scraped off the through hole 111 may be collected through the air duct 122. When the debris is collected, it is determined that the plating strength of the shielding ring 31 is unqualified.

[0066] In this embodiment, a plurality of air ports 16 are provided on the side wall of the splint 11. The air ports 16 are arranged near the non-circular edge of the through hole 111. The air ports 16 are connected to the air duct 122. The connection position can be inside the splint 11, so that when debris is scraped off by the non-circular edge of the through hole 111, the debris is collected through the air ports 16. After the arc plate 12 wraps the connecting column 33, the air pressure in the area where the arc plate 12 is located is reduced through part of these air ports 16, so that the arc plate 12 moves toward the arc notch 112 of the through hole 111.

[0067] After the air is exhausted, the air in the air outlet 16 is exhausted, and the air in the air outlet 16 is exhausted, so that the air in the air outlet 16 is exhausted, and the air in the air outlet 16 is exhausted, so that the air in the air outlet 16 is exhausted, and the air in the air outlet 16 is exhausted, so that the air in the air outlet 16 is exhausted, and the air in the air outlet 16 is exhausted, so that the air in the air outlet 16 is exhausted, and the air in the air outlet 16 is exhausted, so that the air in the air outlet 16 is exhausted, and the air in the air outlet 16 is exhausted, so that the air in the air outlet 16 is exhausted, and the air in the air outlet 16 is exhausted,

[0068] In this embodiment, if debris blocks the air port 16 and / or the air duct 122, it can be judged that the plating of the connecting column 33 and / or the shielding ring 31 is unqualified by the blockage of the air port 16 or the air duct 122. This situation can be manually judged when the metal flange 3 to be inspected is replaced, that is, when the first inspection mechanism 1 and the second inspection mechanism 2 are disassembled, it is manually judged whether there is debris remaining in the through hole 111 and other positions. If so, it is judged that debris blocks the air port 16 and / or the air duct 122 during the inspection process.

[0069] like Figure 5 As shown, in an optional embodiment, the clamping plate 11 is arranged on the connecting plate 13, and the connecting plate 13 is connected to the driving motor 15 through the connecting shaft 14; the driving motor 15 is electrically connected to the control module, and the control module controls the driving motor 15 to drive the connecting shaft 14 to rotate, so as to drive the connecting plate 13 to rotate, so that the through hole 111 moves along the shielding ring 31.

[0070] In this embodiment, after inspecting a connecting column 33 and the corresponding shielding ring 31, the clamping plate 11 can be disassembled and the position of the flange body 32 can be moved, and then the clamping plates 11 can be reassembled to inspect other connecting columns 33 and shielding ring 31.

[0071] In an optional embodiment, the length direction of the clamping plate 11 is radially parallel to the shielding ring 31, and the end face of the clamping plate 11 contacts the inner wall of the flange body 32 in the metal flange 3. When the clamping plate 11 moves, the end face of the clamping plate 11 contacts the inner wall of the flange body 32 to detect the curvature of the inner wall of the flange body 32.

[0072] In this embodiment, if the curvature of the inner wall of the flange body 32 is not up to standard, the rotation of the clamping plate 11 will be prevented.

[0073] In an optional embodiment, the drive motor 15 of the first detection mechanism 1 is arranged above the metal flange 3, the drive motor 15 of the second detection mechanism 2 is arranged below the metal flange 3, and both drive motors 15 are arranged on the base; the rotation center of the clamping plate 11 in the first detection mechanism 1, the rotation center of the clamping plate 11 in the second detection mechanism 2 and the center of the shielding ring 31 are on the same straight line.

[0074] In an optional embodiment, the base is provided with a conveyor belt 4 electrically connected to the control module, and the control module controls the conveyor belt 4 to transport the metal flange 3.

[0075] In this embodiment, the two driving motors 15 are arranged one above the other to avoid obstruction to the movement of the clamping plate 11 .

[0076] In this embodiment, the moving direction of the first detection mechanism 1 during the detection of the shielding ring 31 can be as follows: Figure 7 As shown in F1, the moving direction of the second detection mechanism 2 can be as follows: Figure 7 As shown in F2; when the connecting column 33 is detected, the moving direction of the arc plate 12 can be as follows Figure 8 As shown in G.

[0077] At least one other disclosed embodiment also provides an inspection method using the above-mentioned basin-type insulator metal flange inspection device, including: synchronously moving two clamps 11 in opposite directions along the shielding ring 31 so that the edge of the through hole 111 scrapes the coating; and judging the coating strength of the shielding ring 31 by obtaining information on debris falling after scraping; judging whether the curvature of the shielding ring 31 is qualified by obtaining rotation information of the clamp 11; that is, if there is falling debris, the coating strength is judged to be unqualified; and if the clamp 11 is blocked and cannot move along the shielding ring 31, the curvature of the shielding ring 31 is judged to be unqualified.

[0078] In summary, the present basin-type insulator metal flange detection device includes: a first detection mechanism 1 and a second detection mechanism 2 with the same structure, the shielding ring 31 of the metal flange 3 passes through the first detection mechanism 1 and the second detection mechanism 2, and the first detection mechanism 1 and the second detection mechanism 2 move along the shielding ring 31 to detect the curvature of the shielding ring 31 and the surface coating strength of the shielding ring 31; wherein the first detection mechanism 1 includes: two clamping plates 11 stacked up and down; a through hole 111 is formed between the two clamping plates 11 for the shielding ring 31 to pass through, one end of the through hole 111 is circular, and an arc-shaped notch 112 is provided at the other end so that the edge of the through hole 111 is in full contact with the outer wall of the shielding ring 31; the two clamping plates 11 move synchronously along the shielding ring 31 to scrape the coating through the edge of the through hole 111. If the coating strength is unqualified, debris is scraped off. If the curvature of the shielding ring 31 is unqualified, the clamping plates 11 are blocked and cannot move along the shielding ring 31, thereby achieving simultaneous detection of the curvature and coating strength of the shielding ring 31.
