[0029] 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.

[0030] Example 1: As Figures 1-6 As shown, the present invention provides an ultrasonic water immersion scanning detection device, including a storage frame 1 and a support leg 3. Multiple baffles 2 are fixedly installed on the outer surface of the storage frame 1, forming an immersion tank together with the baffles 2. A support frame 5 is fixedly installed at the other end of the storage frame 1 away from the support leg 3. A transverse moving motor 6 is fixedly installed on the outer surface of the support frame 5. A transverse moving screw 7 is fixedly installed on the output shaft of the transverse moving motor 6. A slide 4 and a transverse moving seat 8 are located at the other end of the storage frame 1 away from the support leg 3. A transverse moving block 9 is threadedly connected to the outer surface of the transverse moving screw 7. A longitudinal displacement seat 11 is fixedly installed on the outer surface of the transverse moving block 9. A sliding block 10 is fixedly installed at the other end of the shift seat 11 away from the transverse shift block 9. A longitudinal shift motor 12 is fixedly installed on the outer surface of the longitudinal shift seat 11. A longitudinal shift lead screw 13 is fixedly installed on the output shaft of the longitudinal shift motor 12. A longitudinal shift block 14 is threaded on the outer surface of the longitudinal shift lead screw 13. A vertical shift seat 15 is fixedly installed on the outer surface of the longitudinal shift block 14. A vertical shift motor 16 is fixedly installed on the outer surface of the vertical shift seat 15. A vertical shift lead screw 17 is fixedly installed on the output shaft of the vertical shift motor 16. A mounting bracket 18 is threadedly connected to the outer surface of the vertical shift lead screw 17. A flaw detection probe assembly 19 is fixedly installed on the outer surface of the mounting bracket 18.

[0031] Specifically, the flaw detection probe assembly 19 includes a connecting frame 1901, a probe housing 1902 fixedly mounted on the outer surface of the connecting frame 1901, connecting lines 1903 on both the inner and outer surfaces of the probe housing 1902, a sealing sleeve 1904 fixedly mounted on the outer surface of the connecting lines 1903, and a probe body 1905 fixedly mounted on the outer surface of the probe housing 1902. The sealing sleeve 1904 corresponds one-to-one with the connecting lines 1903. The advantage is that when the test piece is placed in a water immersion tank, ultrasonic waves are emitted by the probe body 1905 for flaw detection, the connecting lines 1903 are responsible for transmitting signals, and the sealing sleeve 1904 effectively prevents moisture in the water immersion environment from seeping into the probe through the connecting lines 1903, protecting the precision components inside the probe from moisture damage, ensuring stable and accurate flaw detection, extending the service life of the flaw detection probe assembly 19, and reducing maintenance costs.

[0032] Specifically, the sliding block 10 and the slide seat 4 are slidably connected, the longitudinal moving block 14 and the longitudinal displacement seat 11 are slidably connected, and the mounting bracket 18 and the vertical moving seat 15 are slidably connected. The advantage is that during the detection process, when the transverse moving motor 6 drives the transverse moving screw 7 to rotate, causing the transverse moving block 9 and the upper component to move laterally, the slidably connected sliding block 10 and slide seat 4 ensure that the longitudinal displacement seat 11 follows smoothly, avoiding shaking or deviation; the same applies when the longitudinal displacement motor 12 and the vertical moving motor 16 are working. The various sliding connection structures cooperate with each other, enabling the flaw detection probe assembly 19 to move in three-dimensional space and scan the object being detected from all directions.

[0033] Specifically, a wave-damping plate 24 is fixedly installed on the inner surface of the storage rack 1. The outer surface of the wave-damping plate 24 is provided with wave-damping holes 25 and wave-damping grooves 26. The advantage is that when the water waves in the immersion tank encounter the wave-damping plate 24, some of the energy is dispersed through the wave-damping holes 25 and some is conducted and consumed along the wave-damping grooves 26, which effectively reduces the interference of water wave reflection and refraction on flaw detection, makes the ultrasonic wave propagation path more stable, and makes the echo signal received by the probe body 1905 clearer and more accurate, thus improving the flaw detection accuracy.

[0034] Example 2: Figures 2-6 As shown, this is an improvement on the previous embodiment.

[0035] Specifically, the outer surface of the baffle 2 is provided with a water inlet pipe 20 and a water outlet pipe 22, the outer surface of the water inlet pipe 20 is provided with a solenoid valve one 21, the outer surface of the water outlet pipe 22 is provided with a solenoid valve two 23, and the water outlet pipe 22 is located at one end of the water tank away from the sliding seat 4. The advantage is that before the water is injected, it is checked whether the water inlet pipe 20 and the water outlet pipe 22 are connected tightly, and whether the solenoid valve one 21 and the solenoid valve two 23 can normally open and close. When injecting water, open the solenoid valve one 21, water flows into the water tank from the water inlet pipe 20, and after the water level reaches the required level, close the solenoid valve one 21, start detection; after detection is completed, open the solenoid valve two 23, and water is discharged from the water outlet pipe 22. The "L" shaped water inlet pipe 20 and water outlet pipe 22 design facilitates connection of external water pipes, and flange connection at both ends ensures sealing to prevent water leakage; reasonable water inlet and outlet layout combined with solenoid valve control facilitates water injection and drainage operation of the water tank, improves work efficiency, and ensures smooth detection process.

[0036] Specifically, the water inlet pipe 20 and the water outlet pipe 22 are both "L" shaped in cross section, and the water inlet pipe 20 and the water outlet pipe 22 are both flange connected at both ends. The advantage is that on the one hand, it is convenient to flexibly arrange the pipeline in limited space, and adapt to the overall structure of the device; on the other hand, the high-strength sealing of the flange connection eliminates the risk of water leakage, whether it is long-term soaking detection or frequent water change operation, it can stably supply water and drain water, ensure normal operation of the device, and reduce downtime maintenance time caused by pipeline problems.

[0037] Specifically, the outer surface of the storage rack 1 is fixedly provided with supporting legs 3, and the baffle 2 is a transparent baffle. The advantage is that during the detection process, the transparent baffle 2 allows the operator to directly observe the situation inside the water tank, such as water level, presence or absence of foreign matter, and movement state of the flaw detection probe assembly 19, without the need for additional cover opening to check, which not only facilitates real-time monitoring of the detection process and timely discovery and handling of abnormalities, but also avoids frequent opening of the baffle 2 to interfere with the detection environment, ensures detection accuracy, and improves operation convenience and safety.

[0038] Working principle: During use, water can be injected through the inlet pipe 20. A wave-damping plate 24 is fixedly installed on the inner surface of the storage frame 1. When the device is running, water waves in the immersion tank encounter the wave-damping plate 24. Some energy is dispersed through the wave-damping holes 25 on the wave-damping plate 24, and some is dissipated along the wave-damping groove 26, effectively reducing the interference of water wave reflection and refraction on flaw detection. This makes the ultrasonic wave propagation path more stable, and the echo signal received by the probe body 1905 is clearer and more accurate, improving the flaw detection accuracy. The test piece is then placed inside. The transverse movement motor 6 drives the transverse movement screw 7 to rotate, causing the transverse movement block 9 and the longitudinal displacement seat 11 above to move laterally. The sliding block 10 and the sliding seat 4 ensure the longitudinal displacement seat 11 moves smoothly. The longitudinal displacement motor 12 drives the longitudinal displacement screw 13 to rotate, causing the longitudinal displacement seat 11 to move laterally. The vertical moving block 14 and the vertical moving seat 15 above it move longitudinally. The vertical moving motor 16 drives the vertical moving screw 17 to rotate, which drives the mounting frame 18 and the flaw detection probe assembly 19 to move vertically. Through the cooperation of the motors, screws and sliding structures in these three directions, the flaw detection probe assembly 19 can move in three-dimensional space to scan the object being inspected from all directions. At this time, the probe body 1905 emits ultrasonic waves. The ultrasonic waves propagate in water and generate reflected waves after encountering the object being inspected. The reflected waves are received by the probe body 1905. The connecting line 1903 is responsible for transmitting the received signal to the subsequent processing system to detect the internal defects of the object being inspected. The sealing sleeve 1904 can effectively prevent water in the water immersion environment from seeping into the probe through the connecting line 1903, protecting the precision components inside the probe and ensuring stable and accurate flaw detection.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
