The upper half of the vertical box 2 is provided with a sliding channel 4, and a sliding box 5 is slidably connected inside the sliding channel 4. A positioning box 6 is fixedly connected to one end of the two sliding boxes 5 that are close to each other, and the PE pipe body 20 is positioned between the two positioning boxes 6.

[0027] When the two positioning boxes 6 move toward each other, the PE pipe body 20 can be clamped and fixed. Since the positions of the two positioning boxes 6 are adjustable, the pipe wall detection device can meet the needs of PE pipe bodies 20 of different lengths, thereby improving the applicability of the pipe wall detection device.

[0028] In order to control the movement of the sliding box 5 , a block 22 is fixedly connected to one end of the sliding box 5 away from the positioning box 6 , and an electric push rod 15 is fixedly connected between the block 22 and the vertical box 2 .

[0029] To improve the stability of positioning, the positioning box 6 is truncated and has a larger outer diameter near the end of the sliding box 5. The inclined outer wall of the positioning box 6 abuts against the end of the positioning box 6, which can improve the stability of positioning the PE pipe body 20 and meet the requirements of PE pipe bodies 20 of different diameters, further improving the applicability of the pipe wall detection device.

[0030] In actual use, a rubber block may be provided on the outer wall of the positioning box 6 to improve the sealing performance.

There are multiple first air grooves 8, and the multiple first air grooves 8 are equidistantly distributed. The first air grooves 8 cooperate with the second air grooves 11.

[0032] Since the slide box 5 needs to slide inside the slide channel 4, in order to keep the slide box 5 connected with the vertical box 2, the second wind slot 11 is sealed with a second magnet 12, the second magnet 12 is fixedly connected with a second spring 13, the second spring 13 is fixedly connected with a support block 14 at one end away from the second magnet 12, and the support block 14 is fixedly connected to the inner wall of the vertical box 2.

[0033] Specifically, when one of the first air slots 8 corresponds to the second air slot 11, since the magnetic properties of the first magnet 9 and the second magnet 12 on the side close to each other are the same, the first magnet 9 and the second magnet 12 move in opposite directions, so that a gap appears between the first magnet 9 and the first air slot 8, and a gap appears between the second magnet 12 and the second air slot 11, and the sliding box 5 is connected with the vertical box 2;

[0034] In specific use, the sliding channel 4, the second wind slot 11, the second magnet 12 and other structures can be set to a suitable length to ensure that when the sliding box 5 moves, there is always a first wind slot 8 corresponding to it, and the first magnet 9 and the second magnet 12 repel each other.

[0035] In order to improve the accuracy of detection, a support box 16 is arranged between the two vertical boxes 2. The top of the support box 16 is connected to an arc box 17 for supporting the PE pipe body 20. The top of the arc box 17 is provided with a suction hole 18.

[0039] Next, close the solenoid valve on the air inlet end corresponding to the support box 16, open the solenoid valve on the air inlet end connected to the external atmospheric environment, control one of the positioning boxes 6 to move, and fit it to the end of the PE pipe body 20, and blow away the impurities inside the PE pipe body 20 through the air hole 7 to achieve the function of impurity cleaning;

[0040] Then control the other positioning box 6 to move and fit on the other end of the PE pipe body 20 to deliver gas to the inside of the PE pipe body 20.
