Abstract
The invention discloses an angle adjustment calibration test block and an angle adjustment method of an ultrasonic wave water logging transverse wave detection line focusing probe. A test block is installed on an ultrasonic wave water logging detection device, and a line focusing probe of the ultrasonic wave water logging detection device is adjusted according to the test block, so that only a probe frame needs to be moved according to each kind of detected metal pipe bars with different diameters, so that a central line focusing probe is moved to the focusing distance part just above the axles of the metal pipe bars, so that the ultrasonic wave transverse waves at the positive direction and the negative direction can be detected, so that the position of the probe is not required to be adjusted so as to achieve the required incident angle and the corresponding water distance of the ultrasonic wave, and meanwhile, the manufacture of the metal pipe bars with different diameters and the corresponding manual defect test sample is not required in order to find out the corresponding defects effectively via eccentric adjustment parameters through the system testing after probe adjustment. Additionally, according to the method, the line focusing probe can be accurately positioned at the parts of +/-20 degrees, so that the fault detection leakage safety hazard caused by the eccentric distance calculating value error is eliminated.
