Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of chromium-plated superconducting wire processing and detection, in particular to a chromium-plated superconducting wire processing and detection device and a detection method thereof. BACKGROUND

[0002] The chromium-plated superconducting wire processing and detection device is a professional device for detecting the quality of chromium-plated superconducting wire. The chromium-plated superconducting wire has a chromium layer plated on the surface of the superconducting wire to improve its hardness, wear resistance, corrosion resistance, and electrical properties. Such wire has a wide range of applications in the fields of electric power and magnetic levitation, and therefore, the quality thereof is extremely high. The corrosion resistance test is one of the important means for evaluating the corrosion resistance of the chromium-plated layer. The salt spray test can be used to test the corrosion resistance of the chromium-plated layer, and the salt spray test chamber is a device for evaluating and testing the corrosion resistance of products or metal materials by artificially simulating the salt spray environment in the chamber.

[0003] In the prior art, a salt spray tester disclosed in CN212586211U includes a test chamber, a spraying mechanism, and a placing mechanism. The spraying mechanism and the placing mechanism are arranged inside the test chamber. The placing mechanism includes a placing plate arranged in the test chamber and a plurality of support columns. The placing plate is horizontally arranged in the test chamber. Each support column is vertically and spacedly arranged on the placing plate. The upper end of each support column is provided with at least one limiting column. The outer diameter of each limiting column gradually decreases in the upward direction. The support column and the limiting column have the same axis. The test surface of the test product forms a certain angle with the vertical direction.

[0004] However, in actual use, the sprayed salt mist is generally not allowed to be recycled. Even if the sprayed salt mist in the spraying pipe is guided by the guide cover, the salt mist still spreads, but the salt water droplets may still flow back to the spraying pipe, causing mixing of the salt water solution, which is not conducive to the accuracy of the detection data and affects the experimental results.

[0005] Therefore, the present application provides a chromium-plated superconducting wire processing and detection device and a detection method thereof to solve the problem that the sprayed salt mist in the conventional salt spray tester flows back to the spraying pipe, causing pollution of the salt water solution and affecting the accuracy of the detection data. The sprayed salt mist can be collected separately to avoid flowing back to the salt water tank, and the spraying pipe can be self-cleaned to remove salt scale on the wall surface and avoid blocking the pipeline.

[0022] Embodiment two, refer to the attached Figures 1-18 On the basis of the embodiment one, in order to realize the integration of the salt mist detection mechanism and the waste mist collection mechanism, the assembly and disassembly of the two are facilitated. The limiting piece comprises an upper support ring plate 311, an annular embedding groove 3110 is formed in the upper side inner wall of the upper support ring plate 311, an embedding block 3111 is movably connected to the inner surface of the annular embedding groove 3110, and the embedding block 3111 is fixedly installed on the lower surface of the fixed cylinder seat 51; a salt mist flowing cavity 510 is formed in the inner wall of the fixed cylinder seat 51, the salt mist flowing cavity 510 is a tapered cavity with a narrow lower part and a wide upper part, a spiral groove 5100 is formed in the inner side wall of the salt mist flowing cavity 510, an active groove 5101 is formed in the upper side inner wall of the fixed cylinder seat 51, a buffer piece is arranged on the inner side of the active groove 5101, and a lead-out hole 5102 is formed in the inner wall of the active groove 5101; the buffer piece comprises a guide column 533 and an abutting elastic wire 5331, the two ends of the guide column 533 are fixedly connected with the inner walls of the two ends of the active groove 5101, the abutting elastic wire 5331 is movably sleeved on the upper side outer surface of the guide column 533, the upper end of the abutting elastic wire 5331 is fixedly connected with the inner cavity top surface of the active groove 5101, and the lower end of the abutting elastic wire 5331 is fixedly connected with the upper surface of the lifting circular plate 532. In this embodiment, the threaded collar 31 is threadedly connected to the upper end of the spray outer tube 3. A limiting member is used to limit and support the fixed cylinder seat 51. The annular groove 3110 on the upper surface of the upper support ring plate 311 and the insert 3111 connected to the bottom of the fixed cylinder seat 51 form a preliminary limiting. At this point, by rotating the fixed cylinder seat 51, the assembly between the fixed cylinder seat 51 and the top of the spray inner tube 5 is completed. The limiting member here not only supports the installation of the fixed cylinder seat 51 but also connects the connecting wall cylinder 32 and auxiliary scraping components. This is achieved by opening a groove on the side wall of the salt spray flow chamber 510... The spiral groove 5100 is used to guide the salt spray from the inner spray tube 5. It is worth noting that the addition of the buffer can ensure that the top of the lifting plate 532 is not impacted during the rising process of the sealing column 53 and the lifting plate 532. Through the cooperation of the guide column 533 and the abutting elastic wire 5331, the lifting plate 532 is stably guided. When the sealing column 53 and the lifting plate 532 are not pushed, the reverse elastic force of the abutting elastic wire 5331 can drive the sealing column 53 and the lifting plate 532 to reset, thereby sealing the outlet hole 5102.

[0023] Example 3, refer to Appendix Figures 1-18 Based on Embodiment 2, in order to enable the sealing column 53 to move vertically while also rotating horizontally, thereby driving the inner tube rotating component to rotate: The sealing component also includes a lifting circular plate 532, the outer ring surface of which is movably connected to the inner wall of the movable groove 5101. A bearing is provided on the central inner wall of the lifting circular plate 532, and a protrusion 531 is rotatably connected to the inner side of the bearing. The protrusion 531 is fixedly installed on the upper top surface of the sealing column 53. The lower outer surface of the sealing column 53 is movably abutting against the lower inner wall of the fixed cylinder seat 51. A guide vane 530 is fixedly added to the outer side of the sealing column 53. The guide vane 530 is configured as multiple sets and arranged in a circular array about the central axis of the sealing column 53. In this embodiment, refer to Figure 6 and Figure 11As shown, when the salt mist in the spray inner tube 5 is sprayed upward, the salt mist will first drive the blocking plug column 53 to move upward, and the lifting disc 532 moves inside the activity groove 5101. When the salt mist spray pressure reaches a certain degree, the salt mist can be guided through the inclined distribution of the guide vane plate 530 on the surface of the blocking plug column 53 and the design of the spiral groove 5100. The blocking plug column 53 will rotate under the continuous pushing action of the salt mist, which can accelerate the flow speed of the salt mist in the salt mist flow chamber 510, and at the same time, trigger the inner tube rotating part to disturb the salt mist in the inner cavity of the spray inner tube 5. It should be noted that after the blocking plug column 53 and the lifting disc 532 are lifted, the guide hole 5102 is connected with the salt mist flow chamber 510. At this time, the salt mist is discharged to the buffer chamber 5103 through multiple groups of guide holes 5102, and the salt mist is uniformly distributed and sprayed, guiding the spray to spread evenly around.

[0024] Embodiment four, refer to the attached Figures 1-18 On the basis of embodiment three, in order to realize the delicate degree of salt mist spraying, avoid the salt mist from top to bottom to form large water droplets directly falling on the wire surface to affect the detection result: The upper outer surface of the fixed cylinder seat 51 is fixedly installed with a fixed sleeve ring 511. The outer surface of the fixed sleeve ring 511 is threadedly connected with an adapter seat 512. The upper end of the adapter seat 512 is fixedly installed with a conical flow guide cover 513. The outer wall of the conical flow guide cover 513 is uniformly provided with a flow guide groove 5130. The inner side of the adapter seat 512 and the outer side of the fixed cylinder seat 51 form a buffer chamber 5103. The inner wall of the adapter seat 512 is provided with a salt mist dividing part. The salt mist dividing part comprises a spray sub-pipe 5121. The spray sub-pipe 5121 is connected with the inner wall of the buffer chamber 5103. The inner wall of the spray sub-pipe 5121 is fixedly installed with a rice-shaped frame 5122. In this embodiment, the fixed sleeve ring 511 connected to the upper outer ring of the fixed cylinder seat 51 is threadedly connected between the fixed sleeve ring 511 and the adapter seat 512. At this time, the adapter seat 512 is assembled. In order to make the salt mist sprayed from the buffer chamber 5103 to the spray sub-pipe 5121 pass through the rice-shaped frame 5122, the salt mist can be further divided into multiple small units, the uniformity of the salt mist distribution in the salt mist test machine body 1 is increased, and the accuracy of the chromium-plated superconducting wire corrosion resistance detection is further improved. It should be noted that the length of the spray sub-pipe 5121 exceeds the outer wall of the adapter seat 512, which can block the salt water flowing down the flow guide groove 5130 to avoid backflow. It is worth noting that, as shown in the Figure 6 As shown, the maximum diameter of the adapter seat 512 is smaller than the inner diameter of the upper support ring plate 311, so that the salt water flowing down can quickly enter the connecting wall cylinder 32 for collection.

[0025] Embodiment five, refer to the attached Figures 1-18Based on Example 4, in order to achieve auxiliary cleaning of the salt scale generated on the inner and outer walls of the spray inner tube 5 and the inner wall of the spray outer tube 3, and reduce the pressure of subsequent cleaning: The inner tube rotating component includes a connecting rod 54, the upper end of which is fixedly connected to the lower end of the sealing column 53. A rotating blade 541 is fixedly installed on the outer surface of the connecting rod 54. An inner tube scraper 5411 is fixedly connected to the outer side of the rotating blade 541. The outer surface of the inner tube scraper 5411 is movably connected to the inner wall of the spray inner tube 5. An electromagnet is provided on one side surface of the rotating blade 541. The auxiliary wall scraping component includes a concave cylindrical waist 320, a rotating ring 321, and a lower auxiliary ring plate 33. The concave cylindrical waist 320 is located at the middle of the connecting wall cylinder 32 and is integrally formed. The rotating ring 321 is rotatably installed on the outer inner wall of the concave cylindrical waist 320. A toothed ring 322 is fixedly connected to the outer ring surface of the rotating ring 321. A gear 323 meshes with the outer surface of the toothed ring 322. A rotating rod 324 is fixedly installed on the inner surface of the center of the gear 323. The surfaces are rotatably connected to the inner wall of the concave cylinder waist 320. A salt crystal scraper 3241 is fixedly installed on the outer surface of the rotating rod 324. An electromagnet 2 is fixedly installed on the upper surface of the toothed ring 322. The output end of the electromagnet 2 is electrically connected to the electromagnet 1. The lower auxiliary ring plate 33 is fixedly installed at the lower end of the connecting wall cylinder 32. An annular scraper 331 is fixedly installed on the inner annular surface of the lower auxiliary ring plate 33. The outer surface of the annular scraper 331 is movably connected to the outer surface of the spray inner tube 5. The reason for setting the lower auxiliary ring plate 33 and the annular scraper 331 at the bottom of the connecting wall cylinder 32 is to ensure that the annular scraper 331 can make close contact with the outer side wall of the spray inner tube 5 during the process of disassembling the connecting wall cylinder 32 and the threaded collar 31 from the spray outer tube 3, so as to achieve auxiliary cleaning of salt crystals generated on the outer wall of the spray inner tube 5 and reduce the pressure of subsequent cleaning by personnel.

[0026] In this embodiment, reference is made to 13 and Figure 17 As shown, when electromagnet one and electromagnet two are energized, they are two magnetic poles that attract each other. When the inner tube rotating part rotates due to the rotation of the sealing column 53, the connecting rod 54 drives the rotating blade 541 and the inner tube scraper 5411 to clean the side wall of the spray inner tube 5. Electromagnet one rotates synchronously, thus attracting electromagnet two installed on the toothed ring 322. At this time, the toothed ring 322 rotates inside the concave cylinder waist 320 through the rotating ring 321.
