[0023] The fixing plate 46 is fixedly installed on the support frame 7. The two ends of the rotation adjustment frame 14 are rotationally clamped on the support frame 7. The middle parts of the two rotation adjustment gear discs 10 are respectively fixedly connected to the two ends of the rotation adjustment frame 14. The first support limit ring 21 and the second support limit ring 33 are both fixedly connected to the rotation adjustment frame 14. The two ends of the fixed limit frame 28 are fixedly connected to the rotation adjustment frame 14. The air jet ring 23 and the detection ring 25 are located inside the first support limit ring 21. Precise and rapid detection is achieved by the air jet ring 23 and the detection ring 25 closely adhering to the outer wall of the power pipe 2.

[0024] Both ends of the power pipe 2 are clamped in the first support limit ring 21 and the second support limit ring 33, and the front end of the power pipe 2 is sealed and blocked by the sealing plug plate 16, making the detection precise.

[0025] The photosensitive sensors 42 and the nitrogen sensors 44 are wirelessly signal-connected to the controller 5, and the alarm 4 is electrically connected to the controller 5 through a wire, enabling automatic detection and alarm reminder.

[0026] Working principle: Start the third motor 34 in each driving and limiting device 12. The driving wheel 36 can be driven to rotate by the third motor 34. The rotating driving wheel 36 can drive the synchronous rotating wheel 38 and the driving conveying wheel 39 to rotate in a specified direction through the synchronous belt 35. After the front end of the power pipe 2 to be detected is inserted into the middle of the second support frame 32, the power pipe 2 can be driven by the rotating driving conveying wheels 39, so that the power pipe 2 can conveniently slide along the inside of the second support limiting ring 33 and the second support frame 32, and the feeding during detection can be completed easily and labor-saving. And when the power pipe 2 slides a specified distance, the front end of the power pipe 2 enters the first support limiting ring 21, and the front end of the power pipe 2 is hermetically sealed by the sealing plug plate 16. At this time, each third motor 34 stops running, and each first electric push rod 18 is started. The sliding adjustment plate 17 can be made to slide downward synchronously along the first support frame 20 through the first electric push rod 18, so as to drive each extrusion limiting wheel 15 to move. The power pipe 2 is extruded and limited and fixed by the evenly distributed extrusion limiting wheels 15. And during the feeding process, the first motor 9 is started. The first driving gear 8 is driven to rotate by the first motor 9. The rotating first driving gear 8 rotates synchronously through the synchronous driving rod 6. The rotating first driving gear 8 can make the rotating adjustment gear disc 10 rotate. The rotating adjustment gear disc 10 can drive the rotating adjustment frame 14 to rotate. The rotating adjustment frame 14 can drive the three limiting and sealing devices 11, the driving and limiting devices 12 and the moving detection device 13 to rotate, so that the power pipe 2 can be clamped and placed between the driving and limiting device 12 and the limiting and sealing device 11, and the feeding and fixing before detection can be conveniently completed; After each power tube 2 is loaded and positioned, the second electric push rod 45 is started. The second electric push rod 45 drives the sealing disc 40, the first detection plate 41 and the second detection plate 43 to be inserted into the interior of the power tube 2. The sealing disc 40 is in close contact with the inner wall of the power tube 2, so that the interior of the power tube 2 is blocked. At this time, the second motor 30 in the moving detection device 13 on the same side as the induction part 3 is started. The second motor 30 can drive the second driving gear 31 to rotate. The rotating second driving gear 31 can drive the sliding tooth plate 29 to slide slowly along the fixed limiting frame 28, so as to drive the detection ring 25 and the air jet ring 23 to slide along the outer wall of the power tube 2. At this time, the fixing plate 46 drives the sealing disc 40, the first detection plate 41 and the second detection plate 43 to slide slowly along the interior of the power tube 2. At this time, the annular lamp tube 26 and the lamp beads 27 can irradiate strong light on the outer wall of the power tube 2. Nitrogen is transported to the interior of the air jet ring 23 through the nitrogen delivery pipe 22, and nitrogen is discharged from the annular gap arranged inside the air jet ring 23. Therefore, when the detection ring 25 and the air jet ring 23 move slowly along the outside of the power tube 2, when there are gap cracks and holes on the power tube 2, light or gas will enter the interior of the power tube 2. At this time, the photosensitive sensor 42 and the nitrogen sensor 44 can detect and sense the presence of light and gas inside the power tube 2. Therefore, it can be judged that there are gaps and holes on the power tube 2. At this time, the alarm 4 alarms, so that the cracks and holes at specific positions on the power tube 2 can be detected conveniently and accurately. During the detection process, by rotating the adjusting gear disc 10, each power tube 2 can be indirectly driven to rotate, and continuous detection can be realized, greatly improving the detection efficiency.
