[0025] This embodiment will be described in detail with reference to the accompanying drawings when in use.

[0026] In this embodiment, the pipe to be inspected is made of stainless steel. The inspection site is the weld seam at the connection between adjacent stainless steel pipes 1. The weld seam is sprayed with a penetrant test reagent for easy observation. After spraying the test reagent, the weld seam is wiped clean, which makes it easier to identify and improves the accuracy of the inspection.

[0027] The system includes a support plate 2, which is horizontally arranged. Two parallel rotating shafts are rotatably connected to the lower end of the support plate 2. Coaxially arranged traveling wheels 3 are fixedly connected to both ends of the rotating shafts. There are multiple traveling wheels 3, and the outer circumference of each traveling wheel 3 is engaged with the inner side of the stainless steel tube 1, so that the outer circumference of the traveling wheel 3 is always in close contact with the inner side of the stainless steel tube 1. This not only avoids slippage during movement, but also provides stable support for subsequent wiping actions, preventing the support plate 2 from shaking or shifting during wiping. The rotating shafts are connected by a belt, so that each traveling wheel 3 rotates synchronously. The rotating shafts are driven by a drive motor fixedly connected to the lower end surface of the support plate 2.

[0028] A transverse rotating rod 4, coaxially arranged with the stainless steel pipe 1, is rotatably connected to the upper end of the support plate 2. The axis of the transverse rotating rod 4 always coincides with the axis of the stainless steel pipe 1. The transverse rotating rod 4 is driven by a drive motor fixedly connected to the upper end of the support plate 2. The extension direction of the transverse rotating rod 4 is the direction in which the support plate 2 moves driven by the traveling wheels 3. A vertical rod 5, perpendicular to the transverse rotating rod 4, is fixedly connected to the extended end of the transverse rotating rod 4. The middle part of the vertical rod 5 is fixedly connected to the transverse rotating rod 4. A nozzle 6 is fixedly connected to one end of the vertical rotating rod. The extended end of the nozzle 6 has a spray nozzle, which extends obliquely outward. A scrubbing plate 7 is connected to the other end of the vertical rod 5 via an elastic telescopic rod. The outer side of the scrubbing plate 7 is connected to the stainless steel pipe. The inner wall of the vertical rod 5 is engaged with the inner wall of the stainless steel tube 1. When the vertical rod 5 is rotated by the horizontal rotating rod 4, the nozzle 6 sprays the penetrant test reagent at an angle towards the direction of travel. The scrubbing plate 7 at one end of the vertical rod 5 performs a circular motion and scrubbing action. The scrubbing plate 7 consists of two parts: a scrubbing component 12 and a water guiding component 13. The scrubbing component 12 is made of elastic material and adheres to the inner wall of the stainless steel tube 1 through the elasticity of the material. The water guiding component 13 is made of rubber and the side of the water guiding component 13 that contacts the scrubbing component 12 is arranged at an angle. This allows excess liquid generated after scrubbing to be scraped off by the water guiding component 13 and guided to the direction of travel. This keeps the surface clean during subsequent testing.

[0029] The vertical rod 5 and the nozzle 6 are connected at one end with a hollow structure, which is connected to the middle of the horizontal rotating rod 4. A water inlet 8 is provided in the middle of the horizontal rotating rod 4. Water is injected into the water inlet 8, and the injected water will spray out of the nozzle 6. A water supply sleeve 9 is rotatably connected to the horizontal rotating rod 4 at the position corresponding to the water inlet 8. The two ends of the water supply sleeve 9 are located outside the water inlet 8, and the lower end of the water supply sleeve 9 is fixedly connected to the support plate 2. The water supply sleeve 9 is connected to the water tank 11 through the water supply pipe 10, so that water can be continuously injected into the water inlet 8 when the position of the water supply sleeve 9 remains unchanged. This also ensures that the rotating connection part maintains a certain degree of sealing.

[0030] Multiple cameras 14 and lighting lamps are fixedly connected to the support plate 2 to form a camera device. Each camera 14 extends towards a different position on the inner wall of the stainless steel pipe 1. The camera 14, illuminated by the lighting lamp, acquires images. The images can be transmitted in real time through a signal transmission device or stored. During the inspection process, the camera moves inside the stainless steel pipe 1. When it reaches the weld area to be inspected, it is first cleaned. After cleaning, it continues to move to the corresponding position of the camera device and the weld area to acquire images, thereby inspecting the welding quality of the weld.

[0031] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of the claims of this patent application.
