Description

Technical Field

[0001] The utility model relates to the field of ultrasonic detection devices, and particularly relates to a tubular ceramic membrane ultrasonic detection device based on a multi-slider linkage clamping mechanism. Background Art

[0002] As a kind of inorganic membrane, the ceramic membrane has the advantages of high treatment efficiency and simple operation, and has now received extensive attention in many fields such as sewage treatment. However, due to the certain brittleness of the ceramic membrane, damage may occur during production and use, and these damages will affect the water treatment efficiency of the ceramic membrane. Therefore, it is very important to detect defects in the ceramic membrane. When the traditional ultrasonic detection device detects defects in the tubular ceramic membrane, the detection personnel need to hold the ultrasonic probe and then move the probe along the surface of the tubular ceramic membrane. However, due to the special surface of the tubular ceramic membrane, it is difficult for the traditional ultrasonic detection device to ensure full coverage of the detection, resulting in missed detection.

[0003] In 2022, Sun Jin et al. from the Jiangdu Institute of Advanced Equipment Engineering and Technology, Yangzhou University, proposed a non-destructive testing method for complex-curved surface tubular membranes with flexible phased array time delay (publication number: CN114778701A). This invention first determines the array arrangement form of the transducer according to the complex curved surface of the tubular ceramic membrane, and establishes a relevant flexible phased array time delay acoustic field focusing model, and then scans the tubular ceramic membrane to obtain scanning information. However, this method requires a customized flexible probe, and the cost is relatively high.

[0004] Since there are few patents on ultrasonic detection devices for tubular ceramic membranes, for this reason, patents on detection devices for other tubular products made of other materials were further retrieved.

[0005] In 2022, Zhang Fang et al. from Sinosteel Zhengzhou Research Institute of Metal Products Co., Ltd. proposed a scanning device for in-service ultrasonic testing of butt welds of welded steel pipes (authorization announcement number: CN216747577U). This utility model first wraps the fastening hoop around the surface of the steel pipe, then installs the fixing frame and the probe guide rail on the fastening hoop, and finally hangs the probe carrier with the embedded probe on the guide rail, realizing the ultrasonic testing of the steel pipe and avoiding the adverse effects of manual control of the probe. However, when facing the detection tasks of tubular products of different sizes, this device needs to process fastening hoops of corresponding sizes, having problems such as poor interchangeability and cumbersome processing. In 2023, Zhang Xunkai proposed a non-destructive testing device for engineering pipelines (publication number: CN116626175A). This invention first installs a fixing ring on the surface of the pipeline to be detected, then uses fixing bolts to drive the clamping plate to fix the pipeline, and finally pushes the ultrasonic probe to slide along the limiting groove of the fixing ring, capable of achieving full-coverage detection of pipelines of different sizes. Although this device solves the problem of poor interchangeability, its fixing function depends on fixing bolts in different directions, having the problem of poor concentricity. This problem may cause the ultrasonic probe to not be in full contact with the pipeline surface, and this problem becomes more obvious as the diameter gap between the pipeline and the fixing ring expands.
