Defect detection device and method for storage tank bottom plate based on ultrasonic detection

Abstract

The present application relates to an ultrasonic detection-based storage tank floor defect detection device and a method thereof. The device includes a fixing frame, a detector is arranged on the fixing frame, a detection probe is arranged on the detector, and a fixing frame is arranged on the fixing frame to match the storage tank. The two ends of the arc-shaped plate are respectively connected with a number of rollers, a through hole is opened on the fixing frame, a fixing rope is passed through the through hole, one end of the fixing rope is provided with a fixing piece, and the other end of the fixing rope is There is an adjusting block, the fixing piece and the adjusting block are detachably connected by a connecting assembly, and the adjusting block is also provided with an adjusting assembly for retracting and releasing the fixed rope. The roller is pressed between the fixed rope and the storage tank, and the detection probe is inclined and arranged toward the bottom plate of the storage tank. The technical effect of the present application is that the detector can stably detect the defects of the bottom plate of the storage tank through the detection probe, thereby improving the accuracy of the detection result of the defect of the bottom plate of the storage tank.

Description

technical field [0001] The present application relates to the technical field of storage tank inspection, and in particular, to an ultrasonic inspection-based storage tank bottom plate defect detection device and a method thereof. Background technique [0002] Storage tanks are storage containers used to store acid, alkali, alcohol and other refined chemicals. In order to ensure the safety of storage tanks, the bottom plate of storage tanks is usually inspected for defects on a regular basis to reduce the possibility of safety problems caused by storage tank leakage. ;Ultrasonic testing uses ultrasonic technology to detect, which is one of the five conventional non-destructive testing methods, and is often used to detect defects at the bottom of storage tanks. [0003] Announcement No. CN211652706U discloses an ultrasonic testing device for steel structure weld detection, including an ultrasonic weld detector and an ultrasonic detection probe. The front surface of the ultras...

Problems solved by technology

[0004] The above-mentioned technical solution has the following defects: when using the above-mentioned detection device to perform ultrasonic detection on the bottom plate of the storage tank, it is necessary for the staff to hold the detector and the detection probe around the periphery of the storage tank to detect the bottom plate of the storage tank, and the hand-held detection method is difficult to guarantee The stability of the detection probe during the detection process is prone to the situation that the distance between the detection probe and the storage tank is not fixed during the detection process, resulting in poor accuracy of the detection results of the storage tank floor defect
