[0002] At present, as a non-invasive monitoring technology, ultrasonic thickness measurement has been widely used in the field of non-destructive testing. Due to the limited monitoring range of a single ultrasonic probe, it is easy to cause the emergence of monitoring blind spots. In contrast, using multiple probes for monitoring can effectively avoid this risk. However, existing multi-point monitoring technical solutions often only focus on the monitoring range of the probes, but ignore factors such as the applicability of the technology, the coupling effect of the probes, and the maintenance cost. To overcome the deficiencies of the existing technology, the utility model provides an array type thickness measuring device applicable to the field of ultrasonic thickness measurement, aiming to improve the monitoring range, applicability, probe coupling effect and reduce the maintenance cost.

An ultrasonic probe is installed through the center of the base. Two fixed positioning components are installed on the side wall of the ultrasonic probe. Both of the two fixed positioning components are installed with fixing screws. One end of the fixing screw is installed into one of the groups of threaded holes preset on the base. A disc spring is also assembled between the two fixed positioning components and the fixing screws. Fixed clamps are installed on both sides of the outer wall of the base.

[0005] Preferably, the fixed clamp is located in the inner cavity of the groove opened on the outer wall of the base.

[0006] Preferably, the installation direction of the ultrasonic probe is that the probe wire outlet is parallel to the pipeline axis or perpendicular to the pipeline axial direction.

[0007] Preferably, the disc spring is used to offset elastic deformation and increase the pre-tightening force.

[0008] Preferably, the device further includes a control unit, the control unit is electrically connected to the ultrasonic probe, and the control unit is used to process ultrasonic signals in real time and output measurement results.

[0009] An array thickness measuring device applicable to the field of ultrasonic thickness measurement proposed by the present utility model has the following beneficial effects: By adopting an array design, the present utility model can achieve all-round monitoring of the pipe wall thickness, effectively reduce the monitoring blind area, and improve the measurement accuracy and reliability. Two groups of threaded holes provided on the base allow the ultrasonic probe to be adjusted in different directions, thereby adapting to the installation requirements of different pipes and enhancing the applicability of the device. Through the combined use of the fixed positioning component and the disc spring, it can ensure that the ultrasonic probe is closely attached to the outer wall of the pipe, thereby improving the coupling effect of the probe and ensuring the stability of signal transmission.

[0016] Please refer to Figures 1-3, the present utility model provides a technical solution: an array thickness measuring device applicable to the field of ultrasonic thickness measurement, including a pipeline to be measured 1. A plurality of bases 2 are arranged on the outer wall circumference of the pipeline to be measured 1. Two groups of threaded holes are respectively arranged on the bases 2. One group is perpendicular to the axial direction of the pipeline, and the other group is parallel to the axial direction of the pipeline. An ultrasonic probe 3 is installed through the center of the base 2. Two fixed positioning components 7 are installed on the side wall of the ultrasonic probe 3. Two fixed positioning components 7 are both installed with fixing screws 4. One end of the fixing screw 4 is installed into one of the preset threaded holes of the base 2. A disc spring 5 is also assembled between the two fixed positioning components 7 and the fixing screws 4. Fixed clamps 6 are installed on both sides of the outer wall of the base 2. The fixed clamp 6 is located in the inner cavity of the groove opened on the outer wall of the base 2.

The control unit is used to process ultrasonic signals in real time and output measurement results.

[0017] The detailed connection means are well-known techniques in the art. The following mainly introduces the working principle and process. The specific work is as follows: In practical applications, the operator selects a suitable base 2 according to the size and shape of the pipeline to be measured and fixes it on the outer wall of the pipeline. The two groups of threaded holes of the base 2 allow the ultrasonic probe 3 to be finely adjusted in the vertical and horizontal directions to adapt to the installation requirements of different pipelines.

[0018] The ultrasonic probe 3 is positioned through the two fixed positioning components 7 on its side wall to ensure that the probe maintains an appropriate distance and angle from the outer wall of the pipeline. The fixing screw 4 passes through the fixed positioning component 7 and is screwed into the threaded hole of the base 2. Through the elastic action of the disc spring 5, a pre-tightening force is applied to the ultrasonic probe 3 to ensure that the probe is closely attached to the outer wall of the pipeline, thereby improving the signal transmission stability and measurement accuracy.

[0019] After the probe installation and adjustment are completed, the control unit starts to work. The control unit receives and processes ultrasonic signals in real time through the electrical connection with the ultrasonic probe 3. The algorithm built in the control unit can analyze the signals and output the results. The operator can conduct further analysis and decision-making based on the displayed results.

At the same time, the structural design of the fixed clamp 6 ensures the stability of the device in harsh environments and reduces the maintenance cost. The introduction of the control unit not only improves work efficiency but also facilitates the operator to record and analyze measurement data, providing convenience for subsequent data processing and quality control.
