Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, in particular to a fixing device for a non-metallic ultrasonic detector for quickly positioning a probe. Background Art

[0002] The non-metallic ultrasonic detector is an instrument used to detect the internal structure and properties of non-metallic materials. It is based on the principle of ultrasonic detection. It transmits ultrasonic waves into the non-metallic material and receives relevant signals during the propagation of ultrasonic waves for analysis and detection. The non-metallic ultrasonic detector is mainly used to detect the strength, crack depth, concrete homogeneity, damage layer thickness, concrete thickness, pile body integrity, internal structural defects, and internal defects of steel tube concrete. The ultrasonic transducer probe converts the electrical signal into an ultrasonic signal, which is propagated inside the non-metallic material. When the ultrasonic wave encounters defects, interfaces or different media inside the material, reflection, refraction and scattering will occur. Another receiving transducer receives these reflected wave signals, converts them back into electrical signals, and transmits them to the detector for analysis and processing.

[0003] Prefabricated concrete pipe piles are mostly cylindrical in shape. Before use, they need to be inspected for pile integrity and internal structural defects using a non-metallic ultrasonic detector.
