Embodiment 1

[0039] Example 1, such as figure 1 , figure 2 and image 3 as shown,

[0040] The present invention discloses a hydraulic adjustment device for an array type eddy current detection probe, which is used for flawless detection of metal surfaces in electromagnetic eddy current detection. The hydraulic adjustment device includes a hydraulic adjustment chamber 1 and more than one hydraulic column 11. The array of hydraulic columns 11 is distributed on the surface of the hydraulic adjustment cavity 1, and each hydraulic column 11 is used to correspond to a probe coil; wherein, the hydraulic adjustment cavity 1 and the hydraulic column 11 are made of deformable soft materials such as soft rubber As a result, the hydraulic adjustment chamber 1 and the hydraulic column 11 are connected as an overall airtight communication structure that allows liquid or gas to flow.

[0041] Wherein, the hydraulic adjustment chamber 1 is a cylinder, and the hydraulic columns 11 of the same cylinder...

Embodiment 2

[0061] Such as Figure 4 , 5 , 6, and 7, the difference from Embodiment 1 is that the hydraulic adjustment chamber 1 is a semicircular sphere, except that it has the same technical characteristics and functions as Embodiment 1, such as Figure 6 As shown, when the hydraulic adjustment chamber 1 is flattened, it has the effect of changing the elastic force of the hydraulic adjustment device. Additionally, if Figure 7 As shown, the hydraulic column 11 and the probe coil are distributed in a circular arrangement.

Abstract

The invention discloses an array type eddy current detection probe with a hydraulic adjusting device and a detection method thereof. The hydraulic adjusting device of an array type eddy current detection probe is used for metal surface traceless flaw detection in electromagnetic eddy current detection and comprises a hydraulic adjusting cavity (1) and one or more hydraulic columns (11), the hydraulic columns (11) are distributed on the surface of the hydraulic adjusting cavity (1) in an array mode, and each hydraulic column (11) is used for corresponding to one or one set of probe coils. The invention further discloses an array type eddy current detection probe with the hydraulic adjusting device and an array type eddy current detection method with the hydraulic adjusting device. Accordingto the invention, the problem that the stress of the probe is not uniform in array eddy current detection is well solved, so that the array probe coats the curved surface of the test sample with themost balanced elastic pressure, and the optimal test effect is achieved.

Description

technical field [0001] The invention relates to the technical field of eddy current sensor detection, relates to an array type eddy current detection probe for electromagnetic eddy current detection of metal surface flawless flaw detection, in particular to an array type eddy current detection probe and a detection method thereof. Background technique [0002] The advancement of non-destructive testing technology has promoted the development of life-cycle safety systems in aviation, aerospace, electric power, petrochemical, metallurgy, machinery and other fields. As one of the five conventional detection methods, eddy current detection technology has also experienced the development of new technologies such as single frequency, single channel, multi-frequency, multi-channel, spectrum analysis, and large-scale array eddy current detection technology. From the definition in the relevant terms of the country, if there are four or more detection channels, it can be regarded as a...
