In the present embodiment, the upper body housing 5 include...

Embodiment 2

[0066] The present embodiment provides an ultrasonic probe couplant automatic perfusion recovery device, which adds a detection mechanism and display mechanism on the basis of Example 1. Among them, the detection structure includes a level gauge and barometer, while the display mechanism is used to display the values of the level gauge and barometer. The level gauge is used to detect the level of the coupling solution in the reservoir 8, which may reflect the amount of coupling liquid used during the detection process, so that the personnel can make timely replenishment. Barometer is used to detect the air pressure in the sealing chamber, which can prevent the air pump 4 from over-pumping, facilitate the control of the air pressure difference, and also allow personnel to check the sealing in the sealing cavity.

Abstract

The invention discloses an ultrasonic probe coupling agent automatic perfusion recovery device and a method thereof. The device includes an upper main body shell, a lower main body shell, an air pump, an ultrasonic probe, a perfusion mechanism, a filter recovery mechanism and a probe clamping mechanism. The inside of the upper body shell has a sealed cavity, and the lower body shell has a coupling space. The air pump is used to extract the air in the upper main body shell or release the air in the upper main body shell to generate an air pressure difference between the sealed cavity and the coupling space. The ultrasonic probe is used to detect the surface to be tested of the workpiece to be tested, and the filling mechanism is used to fill the coupling space with coupling liquid for coupling with the ultrasonic probe. The filter recovery mechanism includes a collector, a filter tube and a power pump, and the probe clamping mechanism includes a clamping part and a contact part. The invention can ensure that the coupling liquid always fills the gap between the ultrasonic probe and the surface to be tested, realizes automatic liquid-coupled ultrasonic non-destructive testing, and reduces detection differences caused by changes in coupling conditions.

Description

Technical field [0001] The present invention relates to an automatic perfusion recovery device in the field of nondestructive testing technology, in particular to an ultrasonic probe couplant automatic perfusion recovery device, further relates to an ultrasonic probe couplant automatic perfusion recovery method. Background [0002] Ultrasonic non-destructive testing technology is one of the non-destructive testing methods applied in workpiece defect and stress detection, which can realize accurate detection of the location and size of workpiece defects, workpiece thickness inspection and workpiece internal stress detection. Conventional ultrasonic testing requires a certain finish on the inspected surface of the workpiece to be measured, and coupling between the ultrasonic probe and the inspected surface needs to be coupled by a couplant. In the actual ultrasonic testing process, there are detection errors caused by volatilization of couplants, and these errors are often more obv...
