[0002] When ultrasound propagates through a medium, it produces numerous physical, chemical, and biological effects. Ultrasonic waves are widely used in industry, agriculture, national defense, and biomedicine due to their strong penetrating power, excellent directionality, large information-carrying capacity, and ease of rapid and accurate nondestructive testing. Ultrasonic transducers are energy converters that convert alternating electrical signals into acoustic signals, or vice versa, within the ultrasonic frequency range.

[0058] The third transmission assembly 25 includes a support frame 251 , a fifth gear 252 , a sixth gear 253 and a third conveyor belt 254 . The mounting assembly 22 includes a rotating wheel 221 and a clamping plate 222 . The support frame 251 is L-shaped. The support frame 251 has a first section and a second section. The first section and the second section are arranged vertically, the first section is parallel to the mounting plate 21, and the first section and the second section are horizontal. The first section of the support frame 251 is fixed on the first rotating shaft 232, and the side of the first rotating shaft 232 away from the second gear 235 passes through the support frame 251, that is, the support frame 251 is fixedly sleeved on the first rotating shaft 232, and the side of the second rotating shaft 242 away from the fourth gear 245 is fixed with the fifth gear 252, and the side of the second section close to the fifth gear 252 is installed with the sixth gear 253, and a transfer gear is also provided at the connection between the first section and the second section.

The transfer gear is used to change the movement direction of the third conveyor belt 254, and the third conveyor belt 254 as a whole presents a right-angle bend transmission. The side of the sixth gear 253 facing away from the second section is fixedly connected to the rotating wheel 221. The central axis of the sixth gear 253 coincides with the central axis of the rotating wheel 221. A support plate is fixed to the side of the rotating wheel 221 facing away from the sixth gear 253.

The two clamping plates 222 are arranged opposite each other, forming a clamp between the two clamping plates 222. The ultrasonic component is fixedly clamped between the two clamping plates 222. The ultrasonic component is a device that can emit ultrasound.

[0059] When testing the transducer, the electrical control component is connected to each drive component and various limit components to control movement, output, and record data. It is necessary to put an ultrasonic medium such as water into the housing base 1, and the medium must not cover the ultrasonic component. The first drive component 231 is started, and the first drive component 231 drives the first gear 234 to rotate. The first gear 234 drives the second gear 235 to rotate through the first conveyor belt 233. The second gear 235 drives the support frame 251 to rotate through the second rotating shaft 242, thereby driving the mounting assembly 22 and the third transmission assembly 25 to rotate as a whole with the central axis of the first rotating shaft 232 as the rotation center. The second drive member 241 is activated, driving the third gear 244 to rotate. The third gear 244 drives the fourth gear 245 via the second conveyor belt 243. The fourth gear 245 drives the fifth gear 252 via the second rotating shaft 242. The fifth gear 252 drives the sixth gear 253 via the third conveyor belt 254. The sixth gear 253 drives the rotating wheel 221 to rotate as a whole about the central axis of the sixth gear 253. The support plate is eccentrically fixed to the rotating wheel 221, thereby causing the ultrasonic component to rotate in a circular manner about the central axis of the sixth gear 253. The transducer is clamped and fixed by the aforementioned mounting assembly 22. The first transmission assembly 23, the second transmission assembly 24, and the third transmission assembly 25 can then be driven to multiple positions, thereby adjusting the transducer's angle and collecting data at different angles. This allows a single device to perform multi-angle transducer testing without missing any data, thereby reducing uncertainty and error in subsequent use of the entire system. This makes it relatively simple to perform transducer performance testing. It should be noted that all driving parts in this application are provided with hand wheels and can be adjusted manually.

[0060] In this embodiment, if Figures 1 to 7 As shown, the mounting assembly 22 also includes an adjusting wheel 223, two adjusting wheels 223 are provided, a threaded rod is installed on one side of the adjusting wheel 223, the threaded rod passes through the two clamps 222 and is threadedly connected to the clamps 222, and the ultrasonic component is also located between the two threaded rods. The construction personnel can rotate the screw adjusting wheel 223 to drive the two clamps 222 to deform and further clamp the ultrasonic component to prevent the ultrasonic component from falling off during movement.

[0061] In this embodiment, if Figures 1 to 7 As shown, the ultrasonic sound field distribution detection device also includes a three-axis motion structure 3, namely an X-axis motion component 31, a Y-axis motion component 32 and a Z-axis motion component 33, wherein the X-axis is parallel to the direction in which the horizontal section of the mounting plate 21 extends parallel to the Y-axis, and the Z-axis is perpendicular to the X-axis in the horizontal plane; the Z-axis is in the vertical direction.

[0062] The X-axis motion assembly 31 includes an X-axis motor 321, a seventh gear 312, an X-axis connecting plate 313, a first guide rail 314, and a first rack 315. The first guide rail 314 and the first rack 315 are fixed parallel to the X-axis on two opposing outer walls of the housing base 1. Each outer wall corresponds to one first guide rail 314 and one first rack 315, while the other side wall only has one first guide rail 314. The first rack 315 is located below the first guide rail 314. The two X-axis connecting plates 313 are mounted on the two first guide rails 314. The X-axis motor 321 is fixed to the X-axis connecting plate 313 near the first rack 315. The output end of the X-axis motor 321 is fixedly connected to the seventh gear 312, and the central axis of the output end of the X-axis motor 321 coincides with the central axis of the seventh gear 312. The seventh gear 312 meshes with the first rack 315. A crossbeam 34 is fixed between the two X-axis connecting plates 313.

[0063] The Y-axis motion assembly 32 includes: a Y-axis motor 321, an eighth gear 322, a Y-axis connecting plate 323, a second guide rail 324, and a second rack 325. The second rack 325 is fixed to the side of the beam 34 away from the angle positioning structure 2 in a direction parallel to the Y-axis. The second guide rail 324 is fixed to the horizontal top surface in a direction parallel to the Y-axis. In order to ensure the stability of subsequent movement, two second guide rails 324 are provided, and the two guide rails are spaced apart on both sides of the top surface of the beam 34. The Y-axis connecting plate 323 is mounted on the guide rail, and the Y-axis motor 321 is fixed to the Y-axis connecting plate 323. The output end of the Y-axis motor 321 is fixedly connected to the eighth gear 322, and the central axis of the output end of the Y-axis motor 321 coincides with the central axis of the eighth gear 322. The eighth gear 322 is meshed with the second rack 325. The top surface of the Y-axis connecting plate 323 is vertically fixed with a Z-axis bracket 334-Z.

[0064] The Z-axis motion assembly 33 includes: a Z-axis motor 321, a screw moving assembly 332 and a Z-axis connecting plate 333. The Z-axis motor 321 is fixed to the top of the Z-axis bracket 334-Z, and the output end of the Z-axis motor 321 faces downward. The output end of the Z-axis motor 321 is fixedly connected to the screw in the screw moving assembly 332. The Z-axis connecting plate 333 is horizontally fixed to the nut in the screw moving assembly 332. The other end of the Z-axis connecting plate 333 is connected to the fixed structure 4. The fixed structure 4 includes a fixed plate 41, a fixed shaft 42 and a fixed block 43. The fixed plate 41 is vertically fixed to the Z-axis connecting plate 333. The bottom of the fixed plate 41 is fixedly connected to the fixed shaft 42. The fixed shaft 42 extends horizontally along the X-axis direction toward the angle positioning device. The side of the fixed shaft 42 away from the Z-axis connecting plate 333 is fixedly connected to the fixed block 43. The fixing block 43 is V-shaped, with the top corner of the fixing block 43 facing upward. A vertical through hole is provided on the fixing shaft 42, and the sensor 5 is passed through the hole.

[0065] When the sensor 5 needs to be moved so that it faces the ultrasonic component, the X-axis motor 321 is activated. This drives the seventh gear 312 to rotate. The seventh gear 312, in conjunction with the first rack 315, drives the X-axis connecting plate 313 to move along the first guide rail 314 in the X-axis direction, thereby driving the crossbeam 34. Limiters are also provided on both sides of the first rack 315 to limit the position of the X-axis driver and the seventh gear 312, preventing them from falling off the first rack 315 or the first guide rail 314. When the sensor 5 needs to be moved along the Y-axis, the Y-axis motor 321 is activated. This drives the eighth gear 322 to rotate. The eighth gear 322, in conjunction with the second rack 325, drives the Y-axis connecting plate 323 to move along the second guide rail 324 in the Y-axis direction, thereby driving the Z-axis bracket 334-Z movement. When movement in the Z-axis is required, the Z-axis motor 321 is driven, and the Z-axis motor 321 drives the screw in the screw moving assembly 332 to rotate, and then drives the fixed structure 4 to move through the nut. By setting the three-axis motion structure 3 to drive the sensor 5 to move, no matter where the ultrasonic component is, the sensor 5 can be moved directly below it until the sensor 5 is located at a suitable position below the ultrasonic component, so that the distance between the sensor 5 and the ultrasonic component is the optimal detection distance, thereby improving the quality and efficiency of the detection. By setting the fixed shaft 42 and the fixed block 43, a certain distance is set between the sensor 5 and the three-axis motion structure 3 to avoid the occurrence of collision between the angle positioning structure 2 and the three-axis motion structure 3 during use, which may cause device failure.

[0066] The specific steps for using the ultrasonic sound field distribution detection device provided in this embodiment are as follows:

[0067] When testing the transducer, the ultrasonic component is placed between the two clamps 222, and the electrical control components are connected to each drive component and various limit components to control movement and output and record data. It is necessary to put an ultrasonic medium such as water into the housing base 1, and the medium needs to submerge the ultrasonic component. The first drive component 231 is started, and the first drive component 231 drives the first gear 234 to rotate. The first gear 234 drives the second gear 235 to rotate through the first conveyor belt 233. The second gear 235 drives the support frame 251 to rotate through the second rotating shaft 242, thereby driving the mounting assembly 22 and the third transmission assembly 25 to rotate as a whole with the central axis of the first rotating shaft 232 as the rotation center. The second driving member 241 is activated, which drives the third gear 244 to rotate. The third gear 244 drives the fourth gear 245 to rotate via the second transmission belt 243. The fourth gear 245 drives the fifth gear 252 to rotate via the second rotating shaft 242. The fifth gear 252 drives the sixth gear 253 to rotate via the third transmission belt 254. The sixth gear 253 drives the rotating wheel 221 to rotate as a whole about the central axis of the sixth gear 253. The support plate is eccentrically fixed to the rotating wheel 221, thereby causing the ultrasonic component to rotate in a circular manner about the central axis of the sixth gear 253.

[0068] Meanwhile, the drive sensor 5 is located below the ultrasonic component. When movement along the X-axis is required, the X-axis motor 321 is activated, which drives the seventh gear 312 to rotate. The seventh gear 312, in conjunction with the first rack 315, drives the X-axis connecting plate 313 to move along the first guide rail 314 in the X-axis direction, thereby driving the crossbeam 34 to move. Limiters are also provided on both sides of the first rack 315 to limit the position of the X-axis drive component and the seventh gear 312, preventing them from falling off the first rack 315 or the first guide rail 314. When movement along the Y-axis is required, the Y-axis motor 321 is activated, which drives the eighth gear 322 to rotate. The eighth gear 322 and the second rack 325 cooperate to drive the Y-axis connecting plate 323 to move along the second guide rail 324 in the Y-axis direction, thereby driving the Z-axis bracket 334-Z movement. When movement in the Z axis is required, the Z axis motor 321 is driven, and the Z axis motor 321 drives the screw in the screw moving assembly 332 to rotate, and then drives the fixed structure 4 and the sensor 5 to move along the Z axis through the nut until the sensor 5 is located in the appropriate position below the ultrasonic component, and the X axis motor 321, the Y axis motor 321 and the Z axis motor 321 stop moving.

[0069] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
