[0031] Please see Figure 9The sensing unit 3 includes a sealing plate 40, a first detection plate 41, a photosensitive sensor 42, a second detection plate 43, a nitrogen sensor 44, a second electric push rod 45, and a fixing plate 46. The second electric push rod 45 is fixedly mounted on the fixing plate 46. The sealing plate 40 is fixedly connected to the front end of the second electric push rod 45. The first detection plates 41 are symmetrically fixedly mounted on the sealing plate 40, and the second detection plate 43 is fixedly mounted between the two first detection plates 41. The photosensitive sensor 42 is uniformly fixedly mounted on the outer end of the first detection plate 41, and the nitrogen sensor 44 is uniformly fixedly mounted on the outer end of the second detection plate 43. The second electric push rod 45 plays a role in movement and adjustment, and the photosensitive sensor 42 and the nitrogen sensor 44 can realize two detection methods, so that the detection results are accurate.

[0032] The fixed plate 46 is fixedly installed on the support frame 7. The two ends of the rotating adjustment frame 14 are rotatably engaged with the support frame 7. The middle parts of the two rotating adjustment gears 10 are fixedly connected to the two ends of the rotating adjustment frame 14 respectively. The first support limiting ring 21 and the second support limiting ring 33 are both fixedly connected to the rotating adjustment frame 14. The two ends of the fixed limiting frame 28 are fixedly connected to the rotating adjustment frame 14. The air jet ring 23 and the detection ring 25 are located inside the first support limiting ring 21. The air jet ring 23 and the detection ring 25 are in close contact with the outer wall of the power pipe 2 to achieve accurate and rapid detection.

[0033] The two ends of the power pipe 2 are secured in the first support limiting ring 21 and the second support limiting ring 33, and the sealing plate 16 seals and blocks the front end of the power pipe 2, making the detection accurate.

[0034] The photosensitive sensor 42 and the nitrogen sensor 44 are wirelessly connected to the controller 5, and the alarm 4 is electrically connected to the controller 5 via a wire, enabling automatic detection and alarm reminders.

[0035] Working principle: The third motor 34 in each drive limit device 12 is activated, which drives the drive wheel 36 to rotate. The rotating drive wheel 36 drives the synchronous rotating wheel 38 and the drive conveyor wheel 39 to rotate in a specified direction via the synchronous belt 35. After the front end of the power tube 2 to be tested is inserted into the middle of the second support frame 32, the rotating drive conveyor wheels 39 drive the power tube 2, making it easy for the power tube 2 to slide along the second support limit ring 33 and the inside of the second support frame 32, thus completing the loading during testing with ease. After the power tube 2 has slid a specified distance, the front end of the power tube 2 enters the first support limit ring 21, and the front end of the power tube 2 is sealed by the sealing plate 16. At this time, each third motor 34 stops running, and each first electric push rod 18 is activated, which drives the first electric push rod 18 to rotate in a specified direction. The push rod 18 allows the sliding adjustment plate 17 to slide down synchronously along the first support frame 20, thereby driving each extrusion limiting wheel 15 to move. The power tube 2 is extruded, limited, and fixed by the evenly distributed extrusion limiting wheels 15. During the feeding process, the first motor 9 is started, which drives the first drive gear 8 to rotate. The rotating first drive gear 8 rotates synchronously through the synchronous drive rod 6. The rotating first drive gear 8 can cause the rotating adjustment gear 10 to rotate. The rotating rotating adjustment gear 10 can drive the rotating adjustment frame 14 to rotate. The rotating rotating adjustment frame 14 can drive the three limiting sealing devices 11, the drive limiting device 12, and the moving detection device 13 to rotate. This allows the power tube 2 to be securely placed between the drive limiting device 12 and the limiting sealing device 11, facilitating the feeding and fixing process before detection.

[0036] After each power tube 2 has been loaded and positioned, the second electric push rod 45 is activated. The second electric push rod 45 drives the sealing disc 40, the first detection plate 41, and the second detection plate 43 to insert into the interior of the power tube 2. The sealing disc 40 then comes into contact with the inner wall of the power tube 2, sealing its interior. At this time, the second motor 30 in the moving detection device 13, located on the same side as the sensing unit 3, is activated. The second motor 30 drives the second drive gear 31 to rotate. The rotating second drive gear 31 drives the sliding toothed plate 29 to slowly slide along the fixed limiting frame 28, thereby causing the detection ring 25 and the air jet ring 23 to slide along the outer wall of the power tube 2. Meanwhile, the fixed plate 46 drives the sealing disc 40, the first detection plate 41, and the second detection plate 43 to slowly slide along the interior of the power tube 2. At this time, the ring lamp tube 26 and the lamp beads... 27 can irradiate strong light onto the outer wall of the power tube 2, and deliver nitrogen to the interior of the jet ring 23 through the nitrogen delivery pipe 22. The nitrogen is discharged through the annular gap inside the jet ring 23. Therefore, when the detection ring 25 and the jet ring 23 move slowly along the outside of the power tube 2, when there are gaps, cracks, or 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 determined that there are gaps and holes on the power tube 2, and the alarm 4 will sound. Thus, it is possible to conveniently and accurately detect cracks and holes at specific locations on the power tube 2. During the detection process, rotating the adjusting gear 10 can indirectly drive the rotation of each power tube 2, which can achieve continuous detection and greatly improve the detection efficiency.

[0037] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
