Description

Technical Field

[0001] The present invention relates to the technical field of fluorescent penetrant detection, and in particular to a fluorescent penetrant detection line penetration slot with high penetration efficiency. Background Art

[0002] Fluorescent penetrant testing is a non-destructive testing method that uses a penetrant containing fluorescent dyes to penetrate tiny pores or defects on the surface of the object being tested. After removing excess penetrant, ultraviolet light is used to make the fluorescent dye in the defect glow, thereby clearly showing the location, size and shape of the defect, thereby achieving rapid and accurate detection of surface defects of the object being tested. The penetrant slot is a key component in the fluorescent penetrant testing system.

[0003] After searching, the Chinese patent with publication number CN117214193B discloses a combined fluorescent penetrant detection device, including a searchlight mechanism, a positioning mechanism fixedly arranged inside the searchlight mechanism, a cleaning mechanism fixedly arranged on the top of the searchlight mechanism, and a coating mechanism arranged on the bottom of the cleaning mechanism. The fluorescent penetrant detection device can complete the automatic coating operation, improve the coating efficiency, and will not have the problem of incomplete coating of a certain part of the straight pipe. Through this device, the functions of automatic cleaning, automatic coating, automatic flaw detection and recording can be combined together, so that manual operation is not required, and thus the penetration detection efficiency of pipe fittings can be greatly improved.

[0004] The above-mentioned fluorescent penetrant testing device can automatically spray fluorescent dyes on cylindrical materials to achieve fast and comprehensive spraying, but the above-mentioned device cannot automatically adjust according to the diversity and complexity of the samples, and the fixed spray port cannot be flexibly adjusted according to the specific shape and size of the sample. This results in the operator having to manually adjust the equipment when testing different samples, adding additional manual operation links. The lack of adaptability not only reduces the efficiency of fluorescent penetrant testing, but may also lead to waste of fluorescent dyes due to the inability to accurately control the spraying amount and range.

[0005] Therefore, it is necessary to design a fluorescent penetration detection line penetration slot with high penetration efficiency to solve the above problems. Summary of the invention

[0017] The present invention has the following beneficial effects: 1. By setting a fixed column, a sliding cylinder and a smear plate, the system can adapt to samples with different surface shapes and flatness through the relative sliding of the sliding cylinder and the fixed column. The relative sliding of the sliding cylinder can keep the nozzle assembly at the optimal spray height with the sample, which can ensure that the fluorescent material is sprayed evenly and sufficiently on the sample surface, thereby improving the fluorescence penetration efficiency. The smear plate can evenly scrape and press the fluorescent dye onto the sample surface, and can fully immerse it even in grooves or uneven parts, which helps to improve the detection quality and speed up the detection speed, making the entire detection process more efficient. 2. By setting the limit ring and nozzle, the system has high flexibility and can automatically adjust the position of spraying dye according to samples of different lengths. When the sample is short, the nozzle assemblies on both sides are automatically closed because they are not in contact with the sample, avoiding unnecessary spraying and saving dye; 3. By setting the airbag as a clamping element, it can flexibly adapt to pipes of different shapes and sizes (such as round pipes, square pipes, etc.). The deformation ability of the airbag ensures a close fit with the inner surface of the sample, thereby achieving stable and effective clamping, greatly enhancing the versatility and practicality of the system. Through the synergistic effect of the sealing plate and the pressure relief port, the pressure in the system is maintained stable, which not only ensures the stable clamping of the sample by the airbag, but also avoids the potential safety hazards caused by excessive pressure, ensuring the safe and stable operation of the system. Through the linkage mechanism of the movable door and the sealing block, the effect of being unable to work when the door is opened and being able to operate normally when the door is closed is achieved, effectively avoiding the potential safety hazards caused by forgetting to shut down or other situations, and improving the safety and stability of the system; 4. By setting the cooperation of the slider and the slot, the system can automatically realize the linkage between the rotating cylinder and the rotating shaft after the airbag is inflated to stably clamp the sample, ensuring that the sample will not rotate with the system before the clamping is stable, thereby reducing the risk of sample falling off and improving the safety of use. When the airbag clamps stably and drives the sample to rotate, the system can automatically drive the mounting plate and the nozzle assembly down to the working position through the transmission mechanism of the synchronous belt, rotating disk, gear and rack, and can realize the function of automatically starting the fluorescent dye spraying. Through the design of automatic linkage, intelligent drive and precise positioning, the system can efficiently complete the steps of sample clamping, rotation and fluorescent dye penetration, thereby improving the detection efficiency.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] Reference Figure 1-10A fluorescent penetrant detection line penetration slot with high penetration efficiency includes a shell 1; a driving motor 2, fixedly installed in the shell 1; two guide frames 3, symmetrically fixedly installed on the upper top wall inside the shell 1; a guide plate 31, which is U-shaped and slidably installed in the two guide frames 3; a mounting plate 32, fixedly installed on the guide plate 31; a plurality of fixed columns 33, fixedly installed on the end of the mounting plate 32 away from the top surface of the shell 1, and distributed in a linear array; a plurality of sliding cylinders 34, slidably sleeved on the fixed columns 33; a plurality of springs 35, sleeved on the fixed columns 33, and the two ends are respectively fixedly connected to the sliding cylinder 34 and the mounting plate 32; a plurality of connecting plates 36, arranged on the sliding cylinder 34; a plurality of The smear plate 37 is fixedly mounted on the end of the connecting plate 36 away from the mounting plate 32; the movable door 92 is hinged on the housing 1 and adapted to the housing 1; the nozzle assembly is arranged at the end of the sliding cylinder 34 away from the mounting plate 32; the clamping assembly is arranged on the driving motor 2; the linkage assembly is arranged between the clamping assembly and the driving motor 2; the cleaning assembly is arranged in the housing 1; the nozzle assembly includes: two limit rings 4, both fixedly sleeved on the sliding cylinder 34; the sliding ring 41 is slidably sleeved on the sliding cylinder 34 and located between the two limit rings 4; the nozzle 43 is slidably mounted in the sliding cylinder 34; the plug plate 42 is fixedly mounted on the end of the nozzle 43 extending into the sliding cylinder 34; the feed port 44 is opened on the nozzle 43; Among them, the side wall of the sliding ring 41 is fixedly connected to the connecting plate 36, and the connecting plate 36 is fixedly connected to the nozzle 43; the smear plate 37 is made of a flexible rubber strip; the sample is set on the clamping assembly, and the guide plate 31 slides downward along the guide frame 3 under the action of the driving assembly, driving the mounting plate 32 to move downward until the smear plate 37 contacts the sample to be tested, and can continue to move downward a distance. At this time, the smear plate 37 drives the connecting plate 36 and then drives the sliding cylinder 34 to maintain a position in contact with the sample, the fixed column 33 slides into the sliding cylinder 34, and the mounting plate 32 compresses the spring 35 to keep the smear plate 37 in close contact with the sample, and the smear plate 37 abuts the sample and can control the sliding cylinder 34 and the nozzle 43 through the connecting plate 36. The head assembly is always at an optimal distance from the sample surface during the rotation of the sample, and the fluorescent dye is evenly scraped and pressed onto the sample surface through the smear plate 37, which can avoid the problem that the dye sprayed on the grooves or uneven parts cannot be fully immersed. When the mounting plate 32 descends to the working position, the smear plate 37 abutting against the sample drives the connecting plate 36 and then drives the nozzle 43 to move up relative to the sliding cylinder 34, and the plug plate 42 no longer blocks the outlet of the sliding cylinder 34. The dye can be sprayed out from the feed port 44 and the nozzle 43. When the sliding ring 41 moves relatively upward to the top limit ring 4, the sliding ring 41 can drive the sliding cylinder 34 and the fixed column 33 to slide relative to each other, thereby ensuring that the nozzle 43 is in the optimal spraying position unchanged while allowing the fluorescent dye to be sprayed out.

[0022] Reference Figure 1-7 , Fig. 9 and Fig.10The clamping assembly includes: a U-shaped rod 5, fixedly mounted on the output end of the driving motor 2; a connecting rod 51, rotatably mounted on the U-shaped rod 5; a piston plate 52, hinged at the other end of the connecting rod 51; a sealing box 53, fixedly mounted on the inner bottom wall of the shell 1, and slidably connected to the piston plate 52; an air pipe 54, fixedly mounted on the sealing box 53; a rotating shaft 55, fixedly mounted on the other end of the U-shaped rod 5; a rotating cylinder 56, mounted on the rotating shaft 55, and having an air path inside; an air bag 57, fixedly mounted on the rotating cylinder 56, and connected to the air path inside the rotating cylinder 56; a rotating joint 58, mounted on the rotating shaft 55 and connected to the other end of the air pipe 54, and the air outlet end of the rotating joint 58 is connected to the rotating cylinder 56; a voltage stabilizing assembly, arranged on the rotating joint 58 On; a protection component is arranged on the rotary joint 58; the pressure stabilizing component includes: a fixed cylinder 8, fixedly mounted on the rotary joint 58 and connected to the air outlet end of the rotary joint 58; a sealing plate 81, slidably mounted in the fixed cylinder 8; a spring three 82, fixedly mounted between the sealing plate 81 and the fixed cylinder 8; wherein the fixed cylinder 8 is provided with a pressure relief port between the sealing plate 81 and the top surface of the fixed cylinder 8; the protection component includes: a relief groove, which is provided at one end of the rotating cylinder 56 away from the driving motor 2 and is connected to the air path in the rotating cylinder 56; a sealing block 9, which is slidably mounted in the relief groove, and an air hole is provided on its side wall; a spring four 91, which is fixedly mounted between the sealing block 9 and the relief groove; a blocking portion 93, which is fixedly mounted on the movable door 92 and is adapted to the sealing block 9 The airbag 57 is provided with a plurality of reinforcing strips 11 which are arranged in a circular array and are parallel to the length direction of the rotating cylinder 56; the driving motor 2 drives the U-shaped rod 5 to rotate, and then drives the connecting rod 51 to drive the piston plate 52 to reciprocate in the sealing box 53, so that the gas can be pumped into the air path inside the rotating cylinder 56 through the rotating joint 58 in one direction through the two one-way valves arranged in the sealing box 53, and then transmitted to the airbag 57 through the air path. By reciprocatingly pumping air, the airbag 57 can be inflated to fit tightly with the inner wall of the sample and reach a certain pressure state, which is sufficient to provide a certain friction force to drive the sample to move. At this time, the sample can be clamped. When the air pressure threshold is reached inside the airbag 57, the air pressure pushes the sealing plate 81 in the fixed cylinder 8 outward and compresses the elastic Spring three 82, when the sealing plate 81 moves a certain distance, the pressure relief port opened on the fixed cylinder 8 is connected with the air outlet end of the rotary joint 58, so that the gas pumped into the U-shaped rod 5 is released through the pressure relief port. When loading the sample, the movable door 92 is opened first. At this time, the blocking part 93 leaves the sealing block 9, and the sealing block 9 slides out of the clearance groove under the action of the spring four 91, so that the gas in the gas path is released through the air holes on the sealing block 9, so as to realize the timely start of the drive motor 2 and avoid the generation of high pressure. When the loading is completed, the movable door 92 is closed, and the blocking part 93 can press the sealing block 9 into the clearance groove, thereby sealing the clearance groove. The system can pump gas into the airbag 57 to achieve clamping, which can achieve the effect that the system cannot work when the door is opened and can only operate normally when the door is closed.

[0023] Reference Figure 6-8 The linkage assembly includes: four slide grooves 6, which are arranged on the rotating cylinder 56 at positions corresponding to the airbags 57 and are distributed in a ring array; four sliders 61, which are slidably installed in the four slide grooves 6 respectively; a plurality of springs 62, which are fixedly installed between the sliders 61 and the slide grooves 6; four slots 63, which are arranged on the rotating shaft 55 and are adapted to the sliders 61; a driving assembly, which is arranged on the rotating cylinder 56; the driving assembly includes: a fixed plate 7, which is fixedly installed on the inner top wall of the housing 1 at a position corresponding to the rotating cylinder 56; a rotating disk 71, which is rotatably installed on the fixed plate 7; a gear 72, which is fixedly installed The gear 72 is mounted on the rotating disk 71; the synchronous belt 73 is sleeved on the rotating disk 71 and the rotating cylinder 56; the rack 74 is fixedly mounted on the guide plate 31 and is slidably connected to the guide frame 3, and the rack 74 is meshed with the gear 72; the connecting block 75 is slidably mounted in the guide frame 3 and is adapted to the rack 74, and one end of the connecting block 75 is provided with teeth adapted to the rack 74; the yield spring 76 is fixedly mounted between the connecting block 75 and the rack 74; a plurality of return springs 38 are fixedly mounted between the end of the mounting plate 32 away from the fixed column 33 and the inner top wall of the housing 1; when the air pressure in the airbag 57 is reduced, the airbag 57 is rotated to rotate. When the threshold is reached, the airbag 57 generates enough pressure on the inner wall of the sample and thus generates enough friction. At this time, the airbag 57 will generate the same pressure inward under the action of air pressure. The airbag 57 squeezes inward, and the slider 61 can slide inward along the slide groove 6, compressing the spring 2 62 and the slider 61 can be inserted into the slot 63. At this time, the rotation of the shaft 55 will drive the slider 61 and then drive the rotating cylinder 56 and the airbag 57 to rotate. When the rotating cylinder 56 rotates, the rotating disk 71 can be driven to rotate through the synchronous belt 73, and then the gear 72 can be driven to rotate. When the gear 72 rotates, it can drive the meshing member 55 to rotate. The rack 74 slides downward along the guide frame 3, thereby driving the guide plate 31 to move downward, thereby realizing the function of moving the nozzle assembly downward. When the guide plate 31 moves downward to the bottom working position, the gear 72 is meshed with the connecting block 75, and as the gear 72 rotates, it continuously drives the connecting block 75 to compress the yield spring 76. After the yield spring 76 is compressed, the gear 72 can leave the connecting block 75 and continue to rotate. At this time, the connecting block 75 is reset under the action of the yield spring 76, and the action of being pressed down by the gear 72 is repeated, thereby realizing that the rack 74 and the nozzle assembly are always in the working position when the gear 72 rotates.

[0024] Reference Figure 1 and Figure 7The cleaning component includes: a wastewater tank 10, which is fixedly installed in the shell 1 at a position corresponding to the nozzle 43; two fixed blocks 101, which are symmetrically fixedly installed on the top outer wall of the wastewater tank 10 away from the movable door 92; two telescopic rods 102, which are respectively rotatably installed on the fixed blocks 101; two scrapers 103, which are symmetrically slidably installed on the inner side wall of the wastewater tank 10; wherein, one end of the two telescopic rods 102 is hinged to the mounting plate 32, and the other end is hinged to the scraper 103; when the mounting plate 32 moves down to the working position under the action of the gear 72, the scraper 103 can be lifted to the top of the side wall of the wastewater tank 10 through the telescopic rod 102. After the spraying is completed, when the mounting plate 32 moves up, the scraper 103 can be slid downward along the inner wall of the wastewater tank 10 through the telescopic rod 102, and the dye on the side wall of the wastewater tank 10 is cleaned to the bottom of the wastewater tank 10, and then discharged through the wastewater treatment system, which can reduce the residual dye on the side wall of the wastewater tank 10.

[0025] The specific working principle of the present invention is as follows: When fluorescent penetration is performed on a tubular sample to be tested, the movable door 92 is opened, and the sample is set on the clamping assembly. The guide plate 31 slides downward along the guide frame 3 under the action of the driving assembly, driving the mounting plate 32 to move downward until the smear plate 37 contacts the sample to be tested, and then it can continue to move downward for an end distance. At this time, the smear plate 37 drives the connecting plate 36 and then drives the sliding cylinder 34 to maintain a position in contact with the sample, the fixed column 33 slides into the sliding cylinder 34, and the mounting plate 32 compresses the spring 35 to keep the smear plate 37 in close contact with the sample. By setting the splash range and spray amount of the nozzle assembly, the optimal spray height of the nozzle assembly can be determined. The spraying degree is adjusted to ensure uniform and sufficient spraying of the fluorescent material. The smear plate 37 abuts against the sample and can control the sliding cylinder 34 and the nozzle assembly to always be at the best distance from the sample surface through the connecting plate 36 during the rotation of the sample, which can not only achieve sufficient and efficient spraying of the fluorescent dye, but also reduce the waste of the fluorescent dye. In addition, the sprayed dye can be rotated with the sample to the smear plate 37, and the fluorescent dye can be evenly scraped and pressed onto the sample surface through the smear plate 37, avoiding the problem that the dye sprayed on the groove or uneven part cannot be fully immersed. When the mounting plate 32 is at the top of the housing 1, the smear plate 37 drives the connecting plate 36 under the action of gravity. The plate 36 and the nozzle 43 are both at the bottom. At this time, the sliding ring 41 is in contact with the limiting ring 4 at the bottom, and the plug plate 42 blocks the discharge of the sliding cylinder 34. At this time, even if the function of spraying fluorescent dye is started, the dye cannot be sprayed out from the bottom. When the mounting plate 32 is lowered to the working position, the smear plate 37 abutting against the sample drives the connecting plate 36 and then drives the nozzle 43 to move up relative to the sliding cylinder 34. The plug plate 42 no longer blocks the outlet of the sliding cylinder 34, and the dye can be sprayed out from the feed port 44 and the nozzle 43. When the sliding ring 41 moves relatively upward to the top limiting ring 4, the sliding ring 41 can drive the sliding cylinder 34 and the fixed column 33 to slide relative to each other. While ensuring that the nozzle 43 is in the optimal spraying position, the fluorescent dye is allowed to spray out. At this time, if the sample length is short, the nozzle assemblies on both sides can remain in a closed state without spraying the dye because the smear plate 37 does not contact the sample and then slides to release the limit of the nozzle 43, so that the system can be applied to samples of different sizes and the position of spraying the dye can be automatically adjusted according to the sample size. This can not only improve the adaptability of the system to different samples, but also reduce unnecessary spraying to save dye. It should be noted that the working principle and connection method of the storage and supply device of the fluorescent dye are existing mature technologies, which will not be described in detail here. Different pipes (such as round pipes, square pipes, etc.) have different internal structures and sizes. The U-shaped rod 5 is driven to rotate by the driving motor 2, and then the connecting rod 51 is driven to drive the piston plate 52 to reciprocate in the sealing box 53, so that the gas can be pumped into the gas path inside the rotating cylinder 56 through the rotary joint 58 in one direction through the two one-way valves arranged in the sealing box 53, and then transmitted to the airbag 57 through the air path. By reciprocatingly pumping air, the airbag 57 can be inflated to fit tightly with the inner wall of the sample and reach a certain pressure state, which is sufficient to provide a certain friction force to drive the sample to move. At this time, the sample can be clamped, and the airbag 57 is inflated with the sample. The method of abutting against the inside of the sample can be applicable to samples of different shapes. The airbag 57 can produce a certain deformation according to the shape of the sample to fit the inner surface wall of the sample, so as to achieve stable clamping. A reinforcing strip 11 can be set on the airbag 57 to increase the area of ​​the airbag 57 and the inner surface wall of the sample and the friction between the airbag 57 and the sample, and to increase the strength of the airbag 57 to drive the sample to move. The ideal pressure threshold of inflation is preset for the airbag 57. When the air pressure threshold is reached inside the airbag 57, the air pressure can push the sealing plate 81 in the fixed cylinder 8 outward and compress the spring 3 82. When the sealing plate 81 moves a certain distance, the fixed cylinder 8 The opened pressure relief port is connected with the air outlet end of the rotary joint 58, so that the gas pumped into the U-shaped rod 5 is released through the pressure relief port. When the air pressure in the system is low, the sealing plate 81 slides to close the air outlet end, and then the gas continues to be pumped into the airbag 57 to achieve pressurization. The pressure in the system can be maintained stable at a preset value through the sealing plate 81 and the pressure relief port, which can not only ensure the stable clamping of the sample by the airbag 57, but also avoid the hidden dangers caused by excessive pressure. The pressure threshold can be adjusted by adjusting the elastic pressure of the compression spring 3 82 on the sealing plate 81. When loading the sample, the movable door 92 is opened first, and the blocking portion 93 leaves the sealing block 9 at this time. The sealing block 9 slides out of the clearance groove under the action of the spring 91, so that the gas in the gas path is released through the air holes on the sealing block 9, so as to realize the timely start of the driving motor 2, and also ensure that the normal air pressure is maintained in the system, which can avoid the safety hazards caused by forgetting to shut down or other situations when the system is loading samples. When the loading is completed, the movable door 92 is closed, and the blocking part 93 can press the sealing block 9 into the clearance groove, so as to seal the clearance groove. The system can pump gas into the airbag 57 to achieve clamping, which can achieve the effect that the system cannot work when the door is opened and can only operate normally when the door is closed, thereby improving the safety and stability of the system. When the airbag 57 is inflated, the output end of the driving motor 2 drives the U-shaped rod 5 and the rotating shaft 55 to rotate. At this time, the slider 61 is pushed outward along the slide groove 6 for a distance under the action of the spring 2 62. At this time, the rotating cylinder 56 will not rotate with the rotation of the rotating shaft 55. When the air pressure in the airbag 57 reaches the threshold, the airbag 57 generates enough pressure on the inner wall of the sample and can generate enough friction. At this time, the airbag 57 will also generate the same pressure inward under the action of the air pressure. By squeezing the airbag 57 inward, the slider 61 can slide inward along the slide groove 6, compressing the spring The slider 62 and the slider 61 can be inserted into the slot 63. At this time, the rotation of the shaft 55 will drive the slider 61 and then drive the rotating cylinder 56 and the airbag 57 to rotate. The airbag 57 drives the sample to rotate through the friction force. Through the cooperation of the slider 61 and the slot 63, the airbag 57 can automatically realize the linkage between the rotating cylinder 56 and the rotating shaft 55 after stably clamping the sample, and drive the sample to rotate, thereby facilitating the penetration of the fluorescent dye and ensuring that the sample does not rotate with the system before the clamping is stable, reducing the possibility of the sample falling off and improving the safety of use. When the gear 72 rotates, the rotating disk 71 can be driven to rotate through the synchronous belt 73, thereby driving the gear 72 to rotate. When the gear 72 rotates, the rack 74 meshing therewith can be driven to slide downward along the guide frame 3, thereby driving the guide plate 31 to move downward, thereby realizing the function of moving the nozzle assembly downward. When the guide plate 31 moves downward to the bottom working position, the gear 72 is meshed with the connecting block 75, and as the gear 72 rotates, the connecting block 75 is continuously driven to compress the yield spring 76. After the yield spring 76 is compressed, the gear 72 can leave the connecting block 75 and continue to rotate. At this time, the connecting block 75 is reset under the action of the yield spring 76, and the action of being pressed down by the gear 72 is repeated, so that the rack 74 and the nozzle assembly are always in the working position when the gear 72 rotates, which can ensure the stability of the clamping and drive the sample to start rotating, and automatically drive the mounting plate 32 and the nozzle assembly to move down to the working position, and keep the working position unchanged when the sample rotates, so as to stably saturate the sample with fluorescent dye. When the spraying of fluorescent dye is completed, the mounting plate 32 can return to the top of the housing 1 under the action of the reset spring 38 and separate from the sample; When the mounting plate 32 moves down to the working position under the action of the gear 72, the scraper 103 can be lifted to the top of the side wall of the wastewater tank 10 through the telescopic rod 102. After the spraying is completed, when the mounting plate 32 moves up, the scraper 103 can be slid downward along the inner wall of the wastewater tank 10 through the telescopic rod 102, and the dye on the side wall of the wastewater tank 10 is cleaned to the bottom of the wastewater tank 10, and then discharged through the wastewater treatment system, which can reduce the residual dye on the side wall of the wastewater tank 10 and achieve system cleaning.
