Ultrasonic array sensor device with special structure

Abstract

This utility model belongs to the field of ultrasonic testing technology, and in particular to a special structure ultrasonic array sensing non-destructive testing device. The proposed solution includes an ultrasonic sensing testing body; this special structure ultrasonic array sensing non-destructive testing device is equipped with threaded grooves and threaded columns. By activating a first motor, a hollow rotating cylinder can be driven to rotate. Since the threaded column cannot rotate, the rotation of the hollow rotating cylinder causes the threaded column to rise and fall, indirectly driving the rising column to rise and fall. During the rising and falling of the rising column, a pulling plate can be moved. The movement of the pulling plate allows the arc-shaped top plate to slide along a first slide rail via a first slider. The relative movement of the four sets of arc-shaped top plates can quickly position and fix them from the inside of the annular component, avoiding the common problem of most ultrasonic array sensing non-destructive testing devices lacking positioning and fixing components for the annular component, which makes it inconvenient and unstable for non-destructive testing of the annular component.

[0013] This invention proposes a special structure ultrasonic array sensing non-destructive testing device. Compared with the prior art, the advantages of this invention are: 1. This special structure ultrasonic array sensor non-destructive testing device is equipped with threaded grooves and threaded columns. By turning on the first motor, the hollow rotating cylinder can be driven to rotate. Since the threaded column cannot rotate, the rotation of the hollow rotating cylinder can cause the threaded column to rise and fall, indirectly driving the lifting column to rise and fall.

The movement of the pulling plate can cause the arc-shaped top plate to slide through the first slider and the first slide rail. The relative movement of the four sets of arc-shaped top plates can be quickly positioned and fixed from the inside of the ring component.

This special structure ultrasonic array sensing non-destructive testing device is equipped with a first gear plate and an annular rack plate. The operation of the second motor can drive the first gear plate to rotate. The rotation of the first gear plate can cause the annular rack plate to slide through the annular slider and the annular slide rail. Similarly, the sliding of the annular rack plate can cause the second gear plate to rotate. The rotation of the second gear plate can cause the rotating plate to rotate. The rotation of the rotating plate can push the movable plate to move, which indirectly drives the lifting plate to rise and fall. The rising and falling of the lifting plate can remove or put the annular component to be tested from the liquid inside the water tank, avoiding manual handling and increasing the practicality of the device.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-5 This utility model provides a technical solution: a special structure ultrasonic array sensing non-destructive testing device, including an ultrasonic sensing detection body 1, a water tank 2 disposed inside the ultrasonic sensing detection body 1, a lifting plate 3 disposed inside the water tank 2, a fixing frame 4 fixed above the lifting plate 3, a first motor 5 disposed inside the fixing frame 4, a first rotating shaft 6 disposed at the rotating end of the first motor 5, and a hollow rotating cylinder 7 fixed at the other end of the first rotating shaft 6, the inner wall of the hollow rotating cylinder 7 having an opening A threaded groove 8 is provided, and a threaded column 9 is threadedly connected to the inner side of the threaded groove 8. A lifting column 10 is fixed above the threaded column 9. A pulling plate 12 is provided on one side of the lifting column 10. A second rotating shaft 11 is provided at the connection between the lifting column 10 and the pulling plate 12. An arc-shaped top plate 14 is provided at the other end of the pulling plate 12. A third rotating shaft 13 is provided at the connection between the pulling plate 12 and the arc-shaped top plate 14. A first slider 15 is fixed at the bottom end of the arc-shaped top plate 14. A first slide rail 16 is provided on the outer side of the first slider 15.

[0018] Furthermore, a control panel 17 is installed on the front wall of the water tank 2, and an ultrasonic array sensor probe 18 is installed on the inner wall of the water tank 2. The ultrasonic sensing detection body 1 mainly works through the coordinated operation of multiple sets of micro-sensor array elements. First, the system outputs an electrical signal to the array element, which drives the array element to convert electrical energy into ultrasonic waves. The ultrasonic waves are transmitted to the object under test through the matching layer. When the ultrasonic waves propagate in the object, they will be reflected when they encounter defects, and will be transmitted to the bottom surface and reflected again when they encounter defect-free areas. The array element receives these reflected waves, converts them back into electrical signals, and amplifies and reduces noise. Then, through algorithm alignment and superposition of multi-channel signals, information such as the location and size of defects is extracted, and finally a visual image is generated to help determine whether there are problems with the object.

[0019] Furthermore, the hollow rotating cylinder 7 and the first rotating shaft 6 form a rotating structure through the drive of the first motor 5. The hollow rotating cylinder 7 is connected to the threaded column 9 through the threaded groove 8. When the first motor 5 is turned on, the hollow rotating cylinder 7 can be driven to rotate. Since the threaded column 9 cannot rotate, the rotation of the hollow rotating cylinder 7 can cause the threaded column 9 to rise and fall, indirectly driving the lifting column 10 to rise and fall.

[0020] Furthermore, the lifting column 10 forms a rotating structure with the pulling plate 12 via the second rotating shaft 11, and the pulling plate 12 forms a rotating structure with the arc-shaped top plate 14 via the third rotating shaft 13. The arc-shaped top plate 14 forms a sliding structure with the first slider 15 and the first slide rail 16. During the lifting and lowering process of the lifting column 10, the pulling plate 12 can be moved, and the movement of the pulling plate 12 can cause the arc-shaped top plate 14 to slide via the first slider 15 and the first slide rail 16. The relative movement of the four sets of arc-shaped top plates 14 can quickly position and fix them from the inside of the annular component.

[0021] Furthermore, a second motor 19 is fixed to the top surface of the ultrasonic sensing detection body 1. A fourth rotating shaft 20 is provided at the rotating end of the second motor 19. A first gear plate 21 is fixed to the other end of the fourth rotating shaft 20. An annular rack plate 22 is meshed with the lower side of the first gear plate 21. An annular slider 23 is fixed below the annular rack plate 22. An annular slide rail 24 is provided on the outer side of the annular slider 23. The first gear plate 21 and the fourth rotating shaft 20 form a rotating structure through the drive of the second motor 19. The first gear plate 21 and the annular rack plate 22 form a meshing structure. The annular rack plate 22 forms a sliding structure through the annular slider 23 and the annular slide rail 24. Through the operation of the second motor 19, the first gear plate 21 can be driven to rotate. The rotation of the first gear plate 21 can cause the annular rack plate 22 to slide through the annular slider 23 and the annular slide rail 24.

[0022] Furthermore, a second gear plate 25 is provided on the upper side of the annular rack plate 22. A connecting post 26 is fixed to one end of the second gear plate 25, and a bearing 27 is provided on the outer side of the connecting post 26. A rotating plate 28 is fixed to the other end of the connecting post 26. The annular rack plate 22 and the second gear plate 25 form a meshing structure. The second gear plate 25 forms a fixed structure with the rotating plate 28 through the connecting post 26. The connecting post 26 forms a rotating structure with the ultrasonic sensor detection body 1 through the bearing 27. Through the meshing structure of the annular rack plate 22 and the second gear plate 25, the sliding of the annular rack plate 22 can cause the second gear plate 25 to rotate, and the rotation of the second gear plate 25 can cause the rotating plate 28 to rotate.

[0023] Furthermore, a movable plate 30 is provided at the other end of the rotating plate 28. A fifth rotating shaft 29 is provided at the connection between the rotating plate 28 and the movable plate 30, and a sixth rotating shaft 31 is provided at the connection between the lifting plate 3 and the movable plate 30. The rotating plate 28 and the movable plate 30 form a rotating structure through the fifth rotating shaft 29, and the movable plate 30 and the lifting plate 3 form a rotating structure through the sixth rotating shaft 31. The rotation of the rotating plate 28 can push the movable plate 30 to move, indirectly driving the lifting plate 3 to rise and fall. The rising and falling of the lifting plate 3 can remove or put the annular component to be tested from the liquid inside the water tank 2, avoiding manual handling.

[0024] Working principle: First, the first motor 5 is turned on, which drives the hollow rotating cylinder 7 to rotate. Since the threaded column 9 cannot rotate, the rotation of the hollow rotating cylinder 7 causes the threaded column 9 to rise and fall, indirectly driving the lifting column 10 to rise and fall. During the rising and falling of the lifting column 10, the pulling plate 12 can move. The movement of the pulling plate 12 causes the arc-shaped top plate 14 to slide through the first slider 15 and the first slide rail 16. The relative movement of the four sets of arc-shaped top plates 14 can quickly position and fix the annular component from the inside. Then, the operation of the second motor 19 drives the first gear plate 21 to rotate. The rotation of the first gear plate 21 causes the annular rack plate 22 to slide through the annular slider 23 and the annular slide rail 24. The sliding of the annular rack plate 22 causes the second gear plate 25 to rotate. The rotation of the second gear plate 25 causes the rotating plate 28 to rotate. The rotation of the rotating plate 28 can push the movable plate 30 to move, indirectly driving the lifting plate 3 to rise and fall. The rising and falling of the lifting plate 3 can put the annular component to be tested into the liquid inside the water tank 2 for testing.
