Description

Technical Field

[0001] This utility model relates to the field of microcrack detection technology, specifically a device for detecting microcracks in high-pressure vessels based on time-series data aggregation analysis. Background Technology

[0002] High-pressure vessels are sealed containers capable of withstanding pressure, with extremely wide applications and playing a vital role in many sectors of industry, civil use, and scientific research. The safety of high-pressure vessels is paramount; the presence of microcracks can severely impact the safe operation of ultra-high-pressure vessels. If microcracks can be detected before a vessel ruptures, pressure relief and maintenance can be performed, preventing accidents such as ruptures. However, detecting microcracks in vessels has always been a challenging and crucial aspect of the process. Generally, microcracks appear inside the vessel wall before a pressure vessel ruptures. At this stage, the pressure change within the vessel is minimal and difficult to detect. If use continues, these microcracks may continue to expand, eventually leading to a rupture accident.

[0003] To address these issues, it's necessary to regularly inspect used containers to check for potential bursting hazards. Ultrasonic detection technology is a common method in industrial inspection. It transmits ultrasonic waves to the object being tested. When these waves travel through areas with microcracks, they generate fluctuations that are transmitted back to the detector. After signal and noise processing, the acoustic signals are converted into electrical signals. Then, through relevant data analysis methods such as time-series data aggregation analysis, fault diagnosis is performed on the damaged areas, thus identifying the microcrack regions. In existing technologies, inspectors typically manually place the probe surface against the surface of the object being tested and apply appropriate stress. The acoustic crystal inside the probe emits sound waves that are transmitted into the object. During the test, the inspector's hand must continuously hold the probe against the object's surface, causing hand tremors that affect the detection data. Furthermore, the manually applied stress is uncertain, making it impossible to guarantee the consistency of each measurement, leading to measurement errors. Multiple measurements of the same area are required to obtain the most accurate data, impacting the detection speed. Additionally, the lack of post-detection data analysis makes it impossible to propose solutions for related faults. Summary of the Invention

Detailed Implementation

[0022] 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.

[0023] Please see Figure 1-2 A device for detecting microcracks in high-pressure vessels based on time-series data aggregation analysis includes a support ring 1. Three connecting blocks 11 extend outwardly at equal intervals along the circumference of the support ring 1. Each connecting block 11 has a hinge hole 12 at its end, through which a support rod 2 is connected. A telescopic rod is mounted on the support rod 2, and an adjustment knob 21 is located between the telescopic rod and the support rod 2. A magnetic strip 223 is connected to the lower end of the telescopic rod via a foot 22. The height of the telescopic rod can be controlled by adjusting the knob 21, thereby better securing the detection device to the surface of the object being detected via the magnetic strip 223. The device is also mounted on the foot 22. The magnetic strip 223 has a bending function, which allows it to better adhere to the curved surface of the high-pressure tank during installation, resulting in a more secure fit. This ensures that the device does not detach from the object being tested when stress is applied by the torque block 6. The support ring 1 has a threaded hole at its center, in which the torque block 6 is installed. A limit block 4 is located at the lower end of the torque block 6, and a spring 5 connects the limit block 4 to the support ring 1. A hollow cylindrical head 41 is located at the lower end of the limit block 4, and a probe 3 is installed on the cylindrical head 41. The lower end face of the probe 3 has a contact surface 31, and a transmission line 7 is connected to the probe 3. Both the torque block 6 and the limit block 4 have wiring holes at their centers, through which the transmission line 7 connects to the data analyzer. The data analyzer can analyze the generation area and expansion degree of microcracks based on the signals fed back by the ultrasonic waves and provide relevant repair suggestions based on the feedback data.

[0024] like Figure 3-4As shown, one end of the foot 22 is provided with a universal ball joint 222, and the other end is provided with a snap-fit ​​groove 221. The universal ball joint 222 ensures contact and fit in various positions and directions when the device is fixed. There are three springs 5, and their installation positions are consistent with the three connecting blocks 11 extending outward on the support ring 1. The inner cavity of the cylindrical head 41 is provided with a threaded hole, and the probe 3 is installed on the cylindrical head 41 through the threaded hole. Through the pulling between the spring 5 and the limiting block 4, in conjunction with the thread on the torque block 6, the force of the torque block 6 when adjusting the stress can be more precisely controlled, ensuring the accuracy of the detection. The connection between the connecting block 11 and the support rod 2 is hinged. This allows the three support rods 2 to rotate relative to the connecting block 11, better fixing the probe foot 22.

[0025] Working principle: During measurement, the relevant model of probe head 3 is installed on the cylindrical head 41. The transmission line 7 passes through the wiring groove from the lower end of the limiting block 4 and connects to the probe head 3. The probe head 3 is then tightened, and the device is installed on the surface of the object being measured. The height of the three telescopic rods and the angle between the hinge support rod 2 and the connecting block 11 are adjusted by rotating the adjustment knob 21, so that the magnetic strip 223 on the foot 22 at the lower end of the telescopic rod can better adhere to the surface of the object being measured. After fixing the detection device, the torque block 6 is rotated to make the contact surface 31 of the lower end of the probe head 3 fit with the surface of the object being measured. Then, the torque block 6 is rotated to apply appropriate stress. After the adjustment is completed, the switch on the data analysis instrument is turned on so that the probe head 3 emits ultrasonic waves that are transmitted to the object being measured for measurement. The detection results are obtained by analyzing the feedback sound wave data. Multiple measurements can be performed to fit the most accurate data, and then corresponding repair suggestions can be given.

[0026] In summary, this high-pressure vessel microcrack detection device based on time-series data aggregation analysis, through the cooperation of the support ring 1 and the torsion block 6, allows the inspector to apply appropriate stress between the probe head 3 and the surface of the object being inspected by rotating the torsion block 6 according to the inspection requirements. This makes the measurement data more accurate and consistent, reduces the number of measurements, and speeds up the measurement process. By processing and analyzing the measurement data using the time-series data aggregation analysis method, the detection results are more reliable, and corresponding repair suggestions can be given based on the degree of microcrack propagation. The support rod 2 on the connecting block 11, in conjunction with the adjustment knob 21 on the support rod 2, allows for angle and height adjustment according to different surface curvatures of the object being inspected, enabling the device to adapt to most inspection surfaces and increasing its application scenarios. Through the threaded hole on the cylindrical head 41, different models of the probe head 3 can be replaced as needed to meet various inspection requirements.
