Description

Technical Field

[0001] The utility model relates to the technical field of concrete detection, in particular to an ultrasonic device for detecting internal defects of concrete. Background Art

[0002] Ultrasonic instruments for concrete testing use the ultrasonic rebound comprehensive method to detect and locate defects inside concrete. They can detect the depth and width of concrete cracks, etc., and record the quality of concrete by converting ultrasonic length, sound time and amplitude into test data.

[0003] A Chinese patent with publication number CN219201455U was searched and disclosed an ultrasonic testing device for concrete testing.

[0004] The above technical solution includes a storage box and an adjustable shoulder strap, the storage box is provided with adjustable shoulder straps on both sides, a shock-absorbing groove is provided inside the storage box, an ultrasonic detector is placed on the left side inside the shock-absorbing groove, a wire take-up groove is placed inside the shock-absorbing groove, a rubber strip is provided outside the ultrasonic detector, a wire reel is provided on the right side of the ultrasonic detector, the wire take-up groove is placed inside the wire reel, and a crank is provided in the middle of the wire reel. The ultrasonic detection equipment for concrete detection is provided with a crank, a wire reel, a wire take-up groove, and a cleaning ring. After the manual detection is completed, the crank is turned to retract the wire take-up groove that has been inspected into the wire reel. When the wire take-up groove is recycled in the cleaning ring, dust on the surface is removed, and stains are avoided from being brought into the wire reel during storage, thereby solving the problem of dust contamination of cables.

[0005] However, in the above scheme, when performing single-sided flat measurement, it is necessary to mark multiple detection points on the detection plane and then perform detection at the detection points, which is very troublesome and affects the detection efficiency. Before detection, it is necessary to apply a lubricant to fill the gaps on the contact surface. It can also protect the surface of the detection equipment, but the lubricant can easily cause the equipment to deviate, resulting in inaccurate detection results.

[0006] To this end, we propose an ultrasonic device for internal defect detection in concrete. Utility Model Content
