[0027] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0028] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.

[0029] The main function of the ultrasonic imaging centralizer is to keep the probe tube in a coaxial position within the existing hole, so that the energy emitted by the probe tube can be effectively received, thereby improving the data quality.

[0030] The centralizers currently used usually use multiple retaining rings to fix on the probe tube to ensure the coaxial relationship between the probe tube and the centralizer body, and then make the outer diameter of the centralizer match the aperture of the existing hole to achieve the purpose of coaxiality of the three. However, when the aperture of the hole changes, another set of centralizers matching it is required to work. Because the centralizers currently used generally use imported materials, have a long purchase cycle and high prices, the operation cost is very high.

[0031] Based on this, the present embodiment provides a deep hole ultrasonic imaging test method, which can adapt to existing holes of more sizes after the centralizer body and the probe are combined by arranging the centralizer plate and the spring between the outer wall of the centralizer body and the existing hole. The adjustment ability of the spring can effectively improve the practicality and applicability of the centralizer. The setting of the centralizer plate can also be used to improve the stability of the centralizer, thereby improving the data quality of the probe detection.

[0032] The following is a detailed description of the embodiments:

[0033] Reference Figures 1 to 3 As shown, a deep hole ultrasonic imaging test method provided in this embodiment includes the following steps:

[0034] Step 1: Sleeve at least one centralizer body 11 on the outer wall of the probe tube 2;

[0035] Step 2: Press the centralizing sheet 12 toward one side of the centralizer body 11 and compress the spring 13 until the diameter of the entire centralizer is smaller than the diameter of the existing hole 3;

[0036] Step 3: Place the probe tube 2 and the centralizer body 11 together into the existing hole 3;

[0037] Step 4: Insert the probe 2 to the set position to complete the ultrasonic imaging test.

[0038] Among them, by arranging the straightening piece 12 and the spring 13 between the outer wall of the straightening device body 11 and the existing hole 3, the straightening device body 11 and the probe 2 can be combined to adapt to existing holes 3 of more sizes. The adjustment ability of the spring 13 can effectively improve the practicality and applicability of the straightening device. The setting of the straightening piece 12 can also be used to improve the stability of the straightening device, thereby improving the data quality detected by the probe 2.

[0039] In some embodiments, a spring group is disposed on the outer wall of the centralizer body 11 , and the spring group includes no less than three springs 13 .

[0040] In a further embodiment, multiple springs 13 of the same spring group are evenly arranged on the outer wall of the stabilizer body 11 along the circumferential direction; such an arrangement can more accurately locate the coaxiality of the probe 2, the stabilizer body 11 and the existing hole 3, thereby ensuring the coaxiality accuracy of the three.

[0041] In some embodiments, there are multiple spring groups, and the multiple spring groups are arranged on the outer wall of the stabilizer body 11 along the axial direction of the stabilizer body 11; such an arrangement can increase the density of the springs 13 and the stabilizer plates 12, making the coaxial positioning of the stabilizer more accurate.

[0042] In some embodiments, the centralizing piece 12 is disposed at an end of the spring 13 away from the centralizer body 11 .

[0043] Continue to refer to Figure 1 and Figure 2 As shown, the straightening piece 12 is provided with an arc surface structure that matches the inner wall of the existing hole 3; such a configuration can further improve the fit between the straightening piece 12 and the inner wall of the existing hole 3, thereby improving the coaxiality accuracy of the centralizer body 11, the probe 2 and the existing hole 3; in some embodiments, the straightening piece 12 is provided with an arc surface structure bent toward one side of the centralizer body 11 at both ends along the axial direction of the centralizer body 11, so that the straightening piece 12 can play a guiding role when entering the existing hole 3, making it more convenient for the centralizer to enter the existing hole 3.

[0044] Continue to refer to Figure 3As shown, the spring 13 is a leaf spring structure, the center of the spring 13 protrudes toward the side away from the centralizer body 11, and the central part of the spring 13 forms a centralizing piece 12; in some embodiments, at least one end of the spring 13 is slidably connected to the outer wall of the centralizer body 11; in a further embodiment, the spring 13 is arranged parallel to the axial direction of the centralizer body 11; the spring 13 with a leaf spring structure has a better supporting effect and is not easy to tilt due to the friction between the centralizing piece 12 and the inner wall of the existing hole 3; at the same time, the spring 13 with a leaf spring structure can slide with the outer wall of the centralizer body 11 at one end, so that the spring 13 can fit the outer wall of the centralizer body 11 under the state of being compressed to the limit, thereby making the entire centralizer more practical and applicable, and can be suitable for existing holes 3 of smaller sizes; moreover, the spring 13 with a leaf spring structure has a simple structure, is easy to process, has a low cost, and has a low failure rate; it should also be noted that the spring 13 with a leaf spring structure can use its slopes on the front and rear sides along the axial direction of the centralizer body 11 to more easily enter the interior of the existing hole 3 and play a guiding role.

[0045] In some embodiments, the inner wall of the centralizer body 11 is interference fit with the outer wall of the probe tube 2 .
