Description
Technical Field
[0001] This invention belongs to the technical field of water immersion phased array probes, and more specifically, it relates to a water immersion phased array probe mounting device. This invention also relates to an adjustment method for the water immersion phased array probe mounting device. Background Technology
[0002] Water immersion phased array ultrasonic testing is a non-contact inspection method that uses water as the coupling medium. It offers advantages such as stable waveforms, no damage to the probe, high sensitivity, strong resolution, good beam controllability, minimal impact from workpiece surface roughness, and ease of automation. However, with wear and tear on the mechanical transmission components of the phased array ultrasonic testing equipment and maintenance of its mechanical parts, the parallelism between the workpiece surface and the probe surface deteriorates, forming a certain angle. This reduces the directivity of the sound beam incident on the workpiece, decreasing the equipment's detection sensitivity and the accuracy of defect quantification.
[0003] Existing technology includes a device titled "A Slipper-Type Local Water Immersion Low-Frequency Phased Array Probe for Wind Turbine Blade Inspection," with publication number CN210221921U. This technology discloses a slipper-type local water immersion low-frequency phased array probe for wind turbine blade inspection. The probe body is mounted on a water boot using limiting screws and limiting screw clips. A water nozzle is mounted on the water boot and connected to a water pump via a water pipe. A hidden water channel is machined inside the water boot. An encoder is limited by limiting holes and is assembled on the water boot using encoder screws and threaded holes. The wear-resistant screw is screwed in through the wear-resistant screw adjustment hole, with the head of the wear-resistant screw protruding from the bottom of the water boot. The rubber water sealing ring is bonded to the outer edge of the water outlet at the bottom of the water boot with epoxy resin. The lower surface of the piezoelectric chip is plated with a positive electrode layer, and the upper surface of the piezoelectric chip is plated with a negative electrode layer. A matching layer is bonded to the positive electrode layer with epoxy curing.

[0004] However, this technology does not address the technical issues and solutions of this application. Summary of the Invention
[0005] The technical problem to be solved by the present invention is to provide a water-immersion phased array probe installation device that is simple in structure and can effectively solve the problems of large deviation in the directivity of the sound beam incident on the workpiece, low detection sensitivity, and inaccurate quantitative determination of equipment defects caused by the wear of mechanical transmission components and maintenance of mechanical components of phased array superdetection equipment, which leads to the deterioration of the parallelism between the workpiece surface and the probe surface. This ensures the detection quality of wheels.
[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows:
[0007] This invention is a water immersion phased array probe installation device. An opening is provided on the longitudinal adjustment displacement plate. One end of the longitudinal adjustment fixing plate is connected to the longitudinal adjustment displacement plate. The other end of the longitudinal adjustment fixing plate extends through the opening to the other side of the longitudinal adjustment displacement plate. A longitudinal adjustment screw is screwed onto the position where the longitudinal adjustment fixing plate extends through the opening to the other end of the longitudinal adjustment displacement plate.
[0008] The longitudinal adjustment displacement plate is connected to the lateral adjustment fixing plate. The lateral adjustment fixing plate and the lateral adjustment displacement plate are movably connected by two or more connecting pins. A lateral adjustment screw is screwed onto the lateral adjustment displacement plate, and the lateral adjustment screw is screwed onto the lateral adjustment fixing plate.
[0009] The lateral adjustment displacement plate is connected to the probe mounting plate, and a phased array probe is mounted on the probe mounting plate.
[0010] The longitudinal adjustment fixing plate is connected to the longitudinal adjustment fixing plate positioning plate.
[0011] The lower bend of the longitudinal adjustment fixing plate is connected to the lower end of the longitudinal adjustment displacement plate via the longitudinal adjustment plate connecting plate; the upper bend of the longitudinal adjustment fixing plate extends through the opening to a position near the upper end of the longitudinal adjustment displacement plate.
[0012] A longitudinal adjusting screw is screwed into the screw hole on the upper bend.
[0013] The side of the longitudinal adjustment displacement plate is connected to the side of the transverse adjustment fixing plate via a transverse adjustment plate connecting plate, and the transverse adjustment fixing plate and the transverse adjustment displacement plate are arranged in parallel.
[0014] A lateral adjustment screw is screwed into the screw hole on the lateral adjustment displacement plate.
[0015] This invention also relates to a simple adjustment method for a water-immersion phased array probe installation device that effectively solves the problems of large deviation in the directivity of the sound beam incident on the workpiece, low detection sensitivity, and inaccurate quantitative analysis of equipment defects caused by the wear of mechanical transmission components and maintenance of mechanical components in phased array superconducting probe equipment, resulting in poor parallelism between the workpiece surface and the probe surface. This method ensures the detection quality of wheels.
[0016] The adjustment method includes longitudinal adjustment of the phased array probe and the wheel rim surface:
[0017] S1. Rotate the longitudinal adjustment screw clockwise or counterclockwise, and the longitudinal adjustment displacement plate will deflect clockwise or counterclockwise with the longitudinal adjustment plate connecting plate as the fulcrum, thereby adjusting the longitudinal angle between the phased array probe and the wheel rim surface.
[0018] S2. When rotating the longitudinal adjustment screw fulcrum clockwise or counterclockwise, observe the height of the echo on the bottom surface of the wheel rim in the A-scan interface of the phased array probe in the control system. When the echo on the bottom surface of the wheel rim in the A-scan interface reaches its highest point, it is considered that the phased array probe is longitudinally parallel to the wheel rim surface at this time.
[0019] The adjustment method also includes lateral adjustment of the phased array probe and the wheel rim surface:
[0020] S1. Rotate the lateral adjustment screw clockwise or counterclockwise, and the lateral adjustment displacement plate will deflect clockwise or counterclockwise with the lateral adjustment plate connecting plate as the fulcrum, thereby realizing the lateral angle adjustment between the phased array probe and the wheel rim surface;
[0021] S2. When rotating the lateral adjustment screw clockwise or counterclockwise, observe the height of the echo on the bottom surface of the wheel rim in the A-scan interface of the phased array probe in the control system. When the echo on the bottom surface of the wheel rim in the A-scan interface reaches its highest point, it is considered that the phased array probe is laterally parallel to the wheel rim surface.
[0022] The working principle and beneficial effects of the technical solution adopted in this invention are as follows:
[0023] The water-immersion phased array probe installation device of this invention comprises components such as a longitudinal adjustment displacement plate, a longitudinal adjustment fixing plate, a lateral adjustment fixing plate, and a lateral adjustment displacement plate. An opening is provided on the longitudinal adjustment displacement plate. When connecting the components, the longitudinal adjustment fixing plate needs to be fixedly connected to a longitudinal adjustment fixing plate positioning plate. This ensures the longitudinal adjustment fixing plate is fixed in position, preventing swaying or shaking, and also serves as a fixed point for the entire device arrangement. One end of the longitudinal adjustment fixing plate is connected to the longitudinal adjustment displacement plate, establishing a connection between the two. The longitudinal adjustment displacement plate can shift its position relative to the longitudinal adjustment fixing plate when subjected to external force. The other end of the longitudinal adjustment fixing plate extends through the opening to the other side of the longitudinal adjustment displacement plate, where a longitudinal adjustment screw is screwed in. When the longitudinal adjustment plate is connected to the lateral adjustment fixing plate, changes in the angle of the longitudinal adjustment plate will cause changes in the angle of the lateral adjustment fixing plate. The lateral adjustment fixing plate and the lateral adjustment adjustment plate are connected by two or more connecting pins, meaning they can only move closer or further apart. The lateral adjustment fixing plate is fixed in place. Tightening the lateral adjustment screws on the lateral adjustment plate, which are also screwed onto the lateral adjustment fixing plate, will change the position of the lateral adjustment plate relative to the lateral adjustment fixing plate. When the lateral adjustment plate is connected to a phased array probe, its lateral movement will change the lateral position of the phased array probe. Specifically, adjustments are made by rotating the longitudinal adjustment screws clockwise or counterclockwise, changing their relative position to the longitudinal adjustment plate. When the longitudinal adjustment screw is turned clockwise, force is applied to the longitudinal adjustment displacement plate, pushing the upper part of the plate away from the longitudinal adjustment fixing plate. This causes the plate to flip downwards, adjusting its longitudinal angle in one direction, thus changing the longitudinal angle of the phased array probe in that direction. When the longitudinal adjustment screw is turned counterclockwise, force is applied to the longitudinal adjustment displacement plate, pushing its upper part closer to the longitudinal adjustment fixing plate. This causes the plate to flip upwards, ultimately adjusting its longitudinal angle in the opposite direction, thus changing the longitudinal angle of the phased array probe in the opposite direction. Rotating the lateral adjustment screw clockwise or counterclockwise changes its relative position to the lateral adjustment displacement plate.When the lateral adjustment screw is turned clockwise, it applies force to the lateral adjustment displacement plate and the lateral adjustment fixing plate, pushing the lateral adjustment displacement plate gradually away from the lateral adjustment fixing plate, ultimately adjusting the lateral angle of the phased array probe in one direction. When the lateral adjustment screw is turned counterclockwise, it applies force to the lateral adjustment displacement plate and the lateral adjustment fixing plate, pushing the lateral adjustment displacement plate gradually closer to the lateral adjustment fixing plate, ultimately adjusting the lateral angle of the phased array probe in the other direction. The device of this invention has a simple structure and can effectively solve the problems of large beam directivity deviation, low detection sensitivity, and inaccurate quantitative analysis of defects caused by wear of mechanical transmission components and maintenance of mechanical components in phased array superdetection equipment, resulting in poor parallelism between the workpiece surface and the probe surface. This ensures the quality of wheel detection. Attached Figure Description

Detailed Implementation
[0038] The following description, with reference to the accompanying drawings, provides a more detailed explanation of the specific embodiments of the present invention, including the shape and structure of each component, the relative positions and connections between the parts, the functions and working principles of each part:
[0039] As attached Figure 1 -Appendix Figure 10As shown, this invention is a water-immersion phased array probe mounting device. An opening 12 is provided on the longitudinal adjustment displacement plate 4. One end of the longitudinal adjustment fixing plate 5 is connected to the longitudinal adjustment displacement plate 4, and the other end of the longitudinal adjustment fixing plate 5 extends through the opening 12 to the other side of the longitudinal adjustment displacement plate 4. A longitudinal adjustment screw 3 is screwed onto the position where the longitudinal adjustment fixing plate 5 extends through the opening 12 to the other end of the longitudinal adjustment displacement plate 4. The longitudinal adjustment displacement plate 4 is connected to a transverse adjustment fixing plate 8. The transverse adjustment fixing plate 8 and the transverse adjustment displacement plate 9 are movably connected by two or more connecting pins. A transverse adjustment screw 2 is screwed onto the transverse adjustment displacement plate 9, and the transverse adjustment screw 2 is also screwed onto the transverse adjustment fixing plate 8. To address the shortcomings of the prior art, an improved technical solution is proposed. In setting up the structure, components such as the longitudinal adjustment displacement plate 4, the longitudinal adjustment fixing plate 5, the transverse adjustment fixing plate 8, and the transverse adjustment displacement plate 9 are fabricated separately, with an opening 12 provided on the longitudinal adjustment displacement plate 4. When connecting components, the longitudinal adjustment fixing plate 5 needs to be fixedly connected to the longitudinal adjustment fixing plate positioning plate 13. This not only fixes the position of the longitudinal adjustment fixing plate 5, preventing it from swinging or shaking, but also makes the longitudinal adjustment fixing plate 5 a fixed point for the entire device arrangement. One end of the longitudinal adjustment fixing plate 5 is connected to the longitudinal adjustment displacement plate 4, thus connecting one end of the longitudinal adjustment fixing plate 5 to the longitudinal adjustment displacement plate 4. When subjected to external force, the longitudinal adjustment displacement plate 4 can change its position relative to the longitudinal adjustment fixing plate 5. The other end of the longitudinal adjustment fixing plate 5 extends through the opening 12 to the other side of the longitudinal adjustment displacement plate 4, and the longitudinal adjustment screw 3 is screwed onto the position where the longitudinal adjustment fixing plate 5 extends through the opening 12 to the other end of the longitudinal adjustment displacement plate 4. The longitudinal adjustment displacement plate 4 is connected to the lateral adjustment fixing plate 8. Therefore, changes in the angle of the longitudinal adjustment plate 4 will cause changes in the angle of the lateral adjustment fixing plate 8. The lateral adjustment fixing plate 8 and the lateral adjustment displacement plate 9 are movably connected by two or more connecting pins. Thus, the lateral adjustment fixing plate 8 and the lateral adjustment displacement plate 9 can only change their distance from each other. The lateral adjustment fixing plate 8 is in a fixed state. Therefore, by turning the lateral adjustment screw 2 screwed onto the lateral adjustment displacement plate 9, which is also screwed onto the lateral adjustment fixing plate 8, the position of the lateral adjustment displacement plate 9 relative to the lateral adjustment fixing plate 8 will change. The lateral adjustment displacement plate 9 is connected to the phased array probe 1. Therefore, the lateral movement of the lateral adjustment displacement plate 9 will cause a change in the lateral position of the phased array probe 1. Specifically, during adjustment, the relative position of the longitudinal adjustment screw 3 relative to the longitudinal adjustment displacement plate 4 will change by rotating the longitudinal adjustment screw 3 clockwise or counterclockwise.When the longitudinal adjusting screw 3 is turned clockwise, it applies force to the longitudinal adjusting displacement plate 4, pushing the upper part of the plate away from the longitudinal adjusting fixing plate 5. This causes the plate to flip downwards, adjusting its longitudinal angle in one direction, thus changing the longitudinal angle of the phased array probe 1 in one direction. When the longitudinal adjusting screw 3 is turned counterclockwise, it applies force to the longitudinal adjusting displacement plate 4, pushing its upper part closer to the longitudinal adjusting fixing plate 5. This causes the plate to flip upwards, ultimately adjusting its longitudinal angle in another direction, thus changing the longitudinal angle of the phased array probe 1 in another direction. The relative position of the lateral adjusting screw 2 to the lateral adjusting displacement plate 9 changes when the lateral adjusting screw 2 is rotated clockwise or counterclockwise. When the lateral adjustment screw 2 is turned clockwise, it applies force to the lateral adjustment displacement plate 9 and the lateral adjustment fixing plate 8, pushing the lateral adjustment displacement plate 9 gradually away from the lateral adjustment fixing plate 8, ultimately causing the phased array probe 1 to adjust its lateral angle in one direction. When the lateral adjustment screw 2 is turned counterclockwise, it applies force to the lateral adjustment displacement plate 9 and the lateral adjustment fixing plate 8, pushing the lateral adjustment displacement plate 9 gradually closer to the lateral adjustment fixing plate 8, ultimately causing the phased array probe 1 to adjust its lateral angle in the other direction. This invention's device has a simple structure and effectively solves the problems of large beam directivity deviation, low detection sensitivity, and inaccurate quantitative analysis of defects caused by wear of mechanical transmission components and maintenance of mechanical components in phased array superconducting detectors, resulting in poor parallelism between the workpiece surface and the probe surface. It is a water-immersion phased array probe installation device that ensures the detection quality of wheels. The device of the present invention can effectively achieve stepless adjustment of the probe angle, and combined with the real-time monitoring of the reflected wave state of the workpiece (wheel) surface by the software of the control system, it can accurately adjust the parallelism between the phased array probe surface and the workpiece surface.
[0040] The lateral adjustment displacement plate 9 is connected to the probe mounting plate 10, and the phased array probe 1 is mounted on the probe mounting plate 10. This structure ensures a reliable connection to the phased array probe 1.
[0041] The longitudinal adjustment fixing plate 7 is connected to the longitudinal adjustment fixing plate positioning plate 13. This structure enables the longitudinal adjustment fixing plate 7 to be fixedly connected, serving as a fulcrum for the device's operation.
[0042] The lower bend 14 at the lower end of the longitudinal adjustment fixing plate 5 is connected to the lower end of the longitudinal adjustment displacement plate 4 via the longitudinal adjustment plate connecting plate 6; the upper bend 15 at the upper end of the longitudinal adjustment fixing plate 5 extends through the opening 12 to a position near the upper end of the longitudinal adjustment displacement plate 4. A longitudinal adjustment screw 3 is screwed into the screw hole on the upper bend 14. In this structure, with the lower bend 14 at the lower end of the longitudinal adjustment fixing plate 5 connected to the lower end of the longitudinal adjustment displacement plate 4 via the longitudinal adjustment plate connecting plate 6, rotating the longitudinal adjustment screw can change the longitudinal state of the longitudinal adjustment displacement plate 4 relative to the longitudinal adjustment fixing plate 5, thereby achieving longitudinal adjustment of the phased array probe 1.
[0043] The longitudinal adjustment displacement plate 4 is connected to the side of the transverse adjustment fixing plate 8 via the transverse adjustment plate connecting plate 7. The transverse adjustment fixing plate 8 and the transverse adjustment displacement plate 9 are arranged in parallel. A transverse adjustment screw 2 is screwed into the screw hole on the transverse adjustment displacement plate 9. In this structure, the longitudinal adjustment displacement plate 4 is connected to the transverse adjustment fixing plate 8 via the transverse adjustment plate connecting plate 7. When the transverse adjustment screw 2 is rotated, it can cause the transverse state of the transverse adjustment displacement plate 9 to change relative to the transverse adjustment fixing plate 8, thereby realizing the longitudinal adjustment of the phased array probe 1.
[0044] Appendix of the present invention Figure 6 Appendix Figure 7 Appendix Figure 9 Appendix Figure 10 Appendix Figure 11 Appendix Figure 12 In the diagram, the horizontal axis represents time, and the vertical axis represents the height of the echo.
[0045] This invention also relates to a simple adjustment method for a water-immersion phased array probe installation device that effectively solves the problems of large deviation in the directivity of the sound beam incident on the workpiece, low detection sensitivity, and inaccurate quantitative analysis of equipment defects caused by the wear of mechanical transmission components and maintenance of mechanical components in phased array superconducting probe equipment, resulting in poor parallelism between the workpiece surface and the probe surface. This method ensures the detection quality of wheels.
[0046] The adjustment method includes longitudinal adjustment of the phased array probe 1 and the rim surface of the wheel 11:
[0047] S1. Rotate the longitudinal adjusting screw 3 clockwise or counterclockwise. The longitudinal adjusting displacement plate 4 deflects clockwise or counterclockwise with the longitudinal adjusting plate connecting plate 6 as the fulcrum, thereby adjusting the longitudinal angle between the phased array probe 1 and the rim surface of the wheel 11; S2. When rotating the longitudinal adjusting screw fulcrum 3 clockwise or counterclockwise, observe the height of the echo from the bottom surface of the rim in the A-scan interface of the wheel rim of the wheel 11 scanned by the phased array probe 1 in the control system in real time. Figure 6 When the echo from the bottom surface of the wheel rim in the A-scan interface reaches its maximum, such as Figure 7If so, it is assumed that the phased array probe 1 is longitudinally parallel to the rim surface of wheel 11.
[0048] The adjustment method also includes lateral adjustment of the phased array probe 1 and the rim surface of the wheel 11:
[0049] S1. Rotate the lateral adjustment screw 2 clockwise or counterclockwise. The lateral adjustment displacement plate 9 deflects clockwise or counterclockwise with the lateral adjustment plate connecting plate 7 as the fulcrum, thereby adjusting the lateral angle between the phased array probe 1 and the rim surface of the wheel 11; S2. While rotating the lateral adjustment screw 2 clockwise or counterclockwise, observe the height of the echo from the bottom surface of the rim in the A-scan interface of the wheel 11 rim, as scanned in real time by the phased array probe 1 in the control system. Figure 9 When the echo from the bottom surface of the wheel rim in the A-scan interface reaches its maximum, such as Figure 10 If so, it is assumed that the phased array probe 1 is laterally parallel to the rim surface of wheel 11.
[0050] The water-immersion phased array probe installation device of the present invention comprises components such as a longitudinal adjustment displacement plate 4, a longitudinal adjustment fixing plate 5, a lateral adjustment fixing plate 8, and a lateral adjustment displacement plate 9. An opening 12 is provided on the longitudinal adjustment displacement plate 4. When connecting the components, the longitudinal adjustment fixing plate 5 needs to be fixedly connected to the longitudinal adjustment fixing plate positioning plate 13. This ensures the position of the longitudinal adjustment fixing plate 5 is fixed, preventing it from swinging or shaking, and also serves as a fixed point for the entire device arrangement. One end of the longitudinal adjustment fixing plate 5 is connected to the longitudinal adjustment displacement plate 4, establishing a connection between the longitudinal adjustment fixing plate 5 and the connecting longitudinal adjustment displacement plate 4. The longitudinal adjustment displacement plate 4 can change position relative to the longitudinal adjustment fixing plate 5 when subjected to external force. The other end of the longitudinal adjustment fixing plate 5 extends through the opening 12 to the other side of the longitudinal adjustment displacement plate 4, where a longitudinal adjustment screw 3 is screwed. The longitudinal adjustment displacement plate 4 is connected to the lateral adjustment fixing plate 8. Therefore, changes in the angle of the longitudinal adjustment plate 4 will cause changes in the angle of the lateral adjustment fixing plate 8. The lateral adjustment fixing plate 8 and the lateral adjustment displacement plate 9 are movably connected by two or more connecting pins. Thus, the lateral adjustment fixing plate 8 and the lateral adjustment displacement plate 9 can only change their distance from each other. The lateral adjustment fixing plate 8 is in a fixed state. Therefore, by turning the lateral adjustment screw 2 screwed onto the lateral adjustment displacement plate 9, which is also screwed onto the lateral adjustment fixing plate 8, the position of the lateral adjustment displacement plate 9 relative to the lateral adjustment fixing plate 8 will change. The lateral adjustment displacement plate 9 is connected to the phased array probe 1. Therefore, the lateral movement of the lateral adjustment displacement plate 9 will cause a change in the lateral position of the phased array probe 1. Specifically, during adjustment, the relative position of the longitudinal adjustment screw 3 relative to the longitudinal adjustment displacement plate 4 will change by rotating the longitudinal adjustment screw 3 clockwise or counterclockwise. When the longitudinal adjusting screw 3 is turned clockwise, it applies force to the longitudinal adjusting displacement plate 4, pushing the upper part of the plate away from the longitudinal adjusting fixing plate 5. This causes the plate to flip downwards, adjusting its longitudinal angle in one direction, thus changing the longitudinal angle of the phased array probe 1 in one direction. When the longitudinal adjusting screw 3 is turned counterclockwise, it applies force to the longitudinal adjusting displacement plate 4, pushing its upper part closer to the longitudinal adjusting fixing plate 5. This causes the plate to flip upwards, ultimately adjusting its longitudinal angle in another direction, thus changing the longitudinal angle of the phased array probe 1 in another direction. The relative position of the lateral adjusting screw 2 to the lateral adjusting displacement plate 9 changes when the lateral adjusting screw 2 is rotated clockwise or counterclockwise.When the lateral adjustment screw 2 is turned clockwise, it applies force to the lateral adjustment displacement plate 9 and the lateral adjustment fixing plate 8, pushing the lateral adjustment displacement plate 9 gradually away from the lateral adjustment fixing plate 8, ultimately causing the phased array probe 1 to adjust its lateral angle in one direction. When the lateral adjustment screw 2 is turned counterclockwise, it applies force to the lateral adjustment displacement plate 9 and the lateral adjustment fixing plate 8, pushing the lateral adjustment displacement plate 9 gradually closer to the lateral adjustment fixing plate 8, ultimately causing the phased array probe 1 to adjust its lateral angle in the other direction. The device of this invention has a simple structure and can effectively solve the problems of large beam directivity deviation, low detection sensitivity, and inaccurate quantitative analysis of defects caused by wear of mechanical transmission components and maintenance of mechanical components in phased array superdetection equipment, resulting in poor parallelism between the workpiece surface and the probe surface. This ensures the quality of wheel detection.
