Description

Technical Field

[0001] The present invention relates to the technical field of air tightness detection, in particular to an automatic high-voltage air tightness detection platform for magnetic core tubes. Background Art

[0002] As people pay more and more attention to the hygiene and safety of drinking water, magnetic core antibacterial tubes have been widely used in building water supply and drainage, home decoration and other fields because of the high-efficiency antibacterial ion layer (such as silver ions) contained in their inner walls, which can effectively inhibit the growth of harmful bacteria such as Escherichia coli and Staphylococcus aureus.

[0003] The airtightness of magnetic core antibacterial tubing is directly related to the safety of the water supply system and the stability of its antibacterial properties. Leakage not only wastes water resources but also can allow bacteria to invade, destroying the antibacterial environment within the tubing and reducing water quality. Therefore, reliable airtightness testing of magnetic core antibacterial tubing is a key step in ensuring its performance.

[0004] Currently, existing magnetic core tube airtightness testing devices on the market primarily use air pressure tests or water pressure tests to inspect magnetic core tubes. However, existing testing devices are typically only capable of performing simple pressure tests on the entire magnetic core tube. When a leak is detected in the magnetic core tube, existing devices lack effective means of locating the leak point. Maintenance personnel often need to visually inspect the leak section by section. This method is not only inefficient but also difficult to accurately locate tiny leaks or those hidden in complex structures. Therefore, it is necessary to design an automatic high-pressure airtightness testing station for magnetic core tubes. Summary of the Invention

[0022] Reference Figure 1-Figure 2, a magnetic core tube automatic high-voltage airtightness testing platform, including a tube body 1 and a base 2, a fixing component, the fixing component is used to fix the tube body 1 on the base 2, the fixing component is composed of a fixing seat 3, a fixing ring 4 and a clamping ring 5, the fixing seat 3 is fixedly installed on the base 2, the fixing ring 4 is fixedly installed on the fixing seat 3, the clamping ring 5 is hinged on the fixing ring 4, and the side walls of the clamping ring 5 and the fixing ring 4 are fixedly installed with fixing blocks, and the two fixing blocks are fixed by bolts. When the tube body 1 is fixed, the fixation between the clamping ring 5 and the fixing ring 4 is first released, and then the tube body 1 is placed between the two fixing rings 4, and then the two clamping rings 5 are turned over and fixed to the two fixing rings 4 respectively, so that the tube body 1 can be clamped and fixed.

[0023] Reference Figures 1-10 , an automatic high-pressure airtightness test bench for a magnetic core tube, further comprising a mounting seat 10, the mounting seat 10 is slidably mounted on the base 2, and a pressure head 12 is fixedly mounted on the mounting seat 10 through a fixed rod 11, the pressure head 12 is used to input high-pressure gas into the tube body 1, a supercharger 14 is fixedly mounted on the side wall of the mounting seat 10, a one-way air intake pipe 13 connected to the supercharger 14 is fixedly mounted in the fixed rod 11 and the pressure head 12, a connecting seat 15, the connecting seat 15 is slidably mounted on the base 2, and a sliding rod 16 is slidably mounted on the connecting seat 15 through an adjusting assembly, and a detection head 1 that cooperates with the pressure head 12 is fixedly mounted on one end of the sliding rod 16 close to the fixed rod 11 7. A detection component is installed on the detection head 17. The detection component starts to detect after the pressure head 12 inputs high-pressure gas into the tube body 1. The outer surfaces of the pressure head 12 and the detection head 17 are provided with sealing rings for sealing the tube body 1. When the pressure head 12 and the detection head 17 enter the tube body 1 from both ends respectively, the two ends of the tube body 1 are in a sealed state. At this time, the booster 14 is started, and high-pressure gas can be input into the tube body 1 through the one-way air intake pipe 13, so that the internal pressure of the tube body 1 increases. The one-way air intake pipe 13 is a pipeline provided with a one-way valve, and the one-way valve is located in the pressure head 12, which is used to allow the high-pressure gas output by the booster 14 to enter the tube body 1 in one direction.

[0024] The detection assembly consists of a groove 18, a sealing plate 19, a touch rod 21, a touch switch 22, a wire 23, a warning light 24 and a plurality of springs 20. The groove 18 is opened on the side wall of the detection head 17 near the pressure head 12. The sealing plate 19 is slidably sealed and connected in the groove 18. A plurality of springs 20 are installed between the sealing plate 19 and the groove 18. The touch rod 21 is fixedly mounted on the sealing plate 19. The touch switch 22 is fixedly mounted at the bottom of the groove 18, and the position of the touch switch 22 corresponds to that of the touch rod 21. The warning light 24 is fixedly mounted on the slide bar 16. The wire 23 is connected between the warning light 24 and the touch switch 22. When the internal pressure of the tube body 1 increases, the air pressure causes the sealing plate 19 to overcome the elastic force of the spring 20. When the pressure of the tube body 1 input by the booster 14 reaches the specified range but the warning light 24 does not light up, it also indicates that there is a gas leakage problem in the tube body 1.

[0025] Two symmetrically arranged guide blocks 26 are fixedly installed on the inner wall of the connecting seat 15, and two guide grooves 25 are provided on the side wall of the slide rod 16 to cooperate with the corresponding guide blocks 26. The cooperation between the guide blocks 26 and the guide grooves 25 can limit the moving direction of the slide rod 16 on the connecting seat 15. The adjustment component consists of a side groove 27, a fixed rack 28, a servo motor 29 and a driving gear 30. The side groove 27 is provided at the top of the slide rod 16, the fixed rack 28 is fixedly installed in the side groove 27, and the servo motor 29 is provided with a driving gear 30. 9 is fixedly mounted on the side wall of the connecting seat 15, the driving gear 30 is rotatably mounted in the connecting seat 15, and the driving gear 30 is meshed with the fixed rack 28. A driving rod is fixedly connected between the output end of the servo motor 29 and the driving gear 30. When the servo motor 29 rotates, the meshing effect of the driving gear 30 and the fixed rack 28 can be used to make the slide bar 16 slide on the connecting seat 15, thereby adjusting the distance between the detection head 17 and the pressure head 12, so that the air tightness of the tube body 1 of different lengths can be detected.

[0026] A slide groove 6 is provided on the base 2, and two support rods 7 are slidably installed in the slide groove 6, one of the support rods 7 is fixedly connected to the mounting seat 10, and the other support rod 7 is fixedly connected to the connecting seat 15. A servo motor 8 is fixedly installed on the side wall of the base 2, and the output end of the servo motor 8 is fixedly connected to a threaded rod 9. One end of the threaded rod 9 located in the slide groove 6 is threadedly connected to the two support rods 7. When the servo motor 8 is working, the threaded rod 9 can slide along the slide groove 6 through the cooperation of the threaded rod 9 and the two support rods 7, so that the pressure head 12 and the detection head 17 can move in the pipe body 1 at the same time, and the position of the detection area between the two in the pipe body 1 is changed, so that the pipe body 1 can be segmented for detection, which is convenient for finding the leakage point of the pipe body 1, and because the sliding rod 16 can slide on the connecting seat 15, when the pipe body 1 leaks, the size of the detection area can be controlled by adjusting the distance between the detection head 17 and the pressure head 12, so that the leakage point can be found more accurately.

[0027] The fixed-point part is used to locate the leakage point on the pipe body 1. The positioning part includes a storage chamber 31 opened on the detection head 17, and the storage chamber 31 is filled with soapy water. A plurality of one-way spray holes 32 are opened between the end of the detection head 17 close to the pressure head 12 and the bottom of the storage chamber 31. The one-way spray holes 32 are designed to allow the soapy water stored in the storage chamber 31 to be sprayed outward in one direction from the end of the storage chamber 31 close to the slide rod 16. After adjusting the distance between the pressure head 12 and the detection head 17 and applying pressure to the pipe body 1, the sprayed soapy water is located in the detection area. As the servo motor 8 runs, the detection area moves in the pipe body 1. When the leakage point is located in the detection area, the soapy water therein can overflow from the leakage point, so the leakage point position can be accurately determined.

[0028] The detection head 17 is equipped with a pressure assembly that matches the storage chamber 31. The pressure assembly consists of a piston ring 33, a contact ring 35, a plurality of support rods 34, and a plurality of springs 36. The piston ring 33 is slidingly sealed and connected to the storage chamber 31. The plurality of support rods 34 are all sealed and slidably mounted on the detection head 17. One end of the plurality of support rods 34 located in the storage chamber 31 is fixedly connected to the piston ring 33. The contact ring 35 is fixedly mounted between the other ends of the plurality of support rods 34. The plurality of springs 36 are all mounted between the contact ring 35 and the detection head 17. The elastic force of spring 2 36 is used to keep the contact ring 35 away from the detection head 17 when it is not subjected to thrust. When the contact ring 35 is subjected to thrust, it drives the piston ring 33 to move in the storage chamber 31, thereby squeezing out the soapy water for leak point positioning. An addition port communicating with the storage chamber 31 is provided on the side wall of the detection head 17, and a sealing plug 41 is installed on the inner thread of the addition port. The addition port is designed to add soapy water into the storage chamber 31, and the sealing plug 41 is designed to ensure the sealing of the addition port when no soapy water is needed.

[0029] A plurality of locking assemblies that cooperate with the pressure assembly are also installed between the detection head 17 and the pressure head 12. The locking assembly keeps the pressure assembly fixed when the pressure head 12 and the detection head 17 are not close to each other. The locking assembly consists of a positioning block 37, a positioning groove, a receiving groove, a screw rod 38, a fixed gear 39 and a docking rack 40. The positioning block 37 receiving groove is opened in the detection head 17, and the positioning block 37 is slidably installed in the receiving groove. The positioning groove is opened on the side wall of the support rod 34, and the positioning groove cooperates with the positioning block 37. The screw rod 38 is rotatably installed on the detection head 17, and the screw rod 38 is located in the receiving groove. One end is threadedly connected to the positioning block 37, the fixed gear 39 is fixedly mounted on the screw rod 38, the docking rack 40 is fixedly mounted on the pressure head 12, and the docking rack 40 cooperates with the fixed gear 39. When the docking rack 40 is separated from the fixed gear 39, the screw rod 38 is in a stationary state. At this time, the positioning block 37 is located in the positioning groove, so the support rod 34 and the detection head 17 maintain a fixed position. Therefore, the increase in pressure in the tube body 1 at this time will not cause the piston ring 33 to move in the storage chamber 31, which can avoid the problem of soapy water spraying out during the overall air tightness test of the tube body 1, making it difficult to clean the inside of the tube body 1 later; When there is a gas leakage problem in the pipe body 1, the detection head 17 is first moved closer to the pressure head 12, and then the booster 14 is started to increase the pressure in the pipe body 1 so that the warning light 24 lights up. Then, the detection head 17 is moved closer to the pressure head 12 for a certain distance again, so that the pressure head 12 pushes the contact ring 35 close to the detection head 17, so that soapy water is sprayed out. Then, the servo motor 8 is started to move the detection head 17 and the pressure head 12 at the same time in the pipe body 1, so as to achieve accurate positioning of the leakage point.

[0030] The inner diameter of the contact ring 35 is larger than the diameter of the sealing plate 19. The size design here can avoid the sealing plate 19 and the contact ring 35 from contacting each other and causing movement interference. The length of the docking rack 40 is less than or equal to the distance between the bottom of the storage chamber 31 and the end of the detection head 17 away from the slide rod 16. The length of the docking rack 40 is greater than or equal to the depth of the groove 18. The size design here can ensure that when the pressure head 12 contacts and pushes the contact ring 35, the locking assembly has released the position limit of the support rod 34.

[0031] Both servo motor 1 8 and servo motor 2 29 can adopt ACM6004M2H model servo motors. The touch switch 22, warning light 24 and supercharger 14 are existing products. Their working principles and specific structures are not explained here. In addition, a controller can be fixedly installed on the base 2, and the controller can be electrically connected to the servo motor 1 8, servo motor 2 29 and supercharger 14 to automatically control the operation of servo motor 1 8, servo motor 2 29 and supercharger 14. The controller can specifically adopt KV-16AT model controller.

It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention.
