[0019] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0020] like Figure 1-3As shown, a circular tube flaw detection device includes a base plate 1. Transmission components 2 are symmetrically arranged at both ends of the top of the base plate 1. The transmission components 2 include a square shell 21. A U-shaped plate 22 is symmetrically slidably connected inside the square shell 21. A conduction roller 23 for clamping the circular tube is rotatably connected inside the U-shaped plate 22. A detection component 3 is arranged in the middle of the top of the base plate 1. Slide grooves 24 are symmetrically arranged on both sides of the square shell 21. A slider 25 is fixedly connected to both sides of the U-shaped plate 22. Two sliders 25 are slidably connected inside the corresponding slide grooves 24. A reduction motor 26 is fixedly connected to one end of one slider 25. The output shaft of the reduction motor 26 is fixedly connected to one end of the conduction roller 23.

[0021] According to the above structure, in use, the round tube passes between the two transmission rollers 23 of the transmission component 2. The reduction motor 26 drives one of the transmission rollers 23 to rotate, thereby driving the round tube forward. When the round tube passes the detection component 3, the detection component 3 will detect the round tube and thus perform flaw detection. In use, the distance between the two transmission rollers 23 can be adjusted by sliding the two U-shaped plates 22, thereby adapting to round tubes of different diameters.

[0022] like Figure 2 and 3 As shown, arc-shaped protrusions 27 are provided in the middle of both sides of the square shell 21, and support frames 210 are fixedly connected to both sides of the square shell 21. The bottom end of the support frame 210 is fixedly connected to the top end of the substrate 1.

[0023] According to the above structure, during use, the square shell 21 is fixedly mounted on the base plate 1 by the support frame 210. The arc-shaped protrusion 27 is set to provide space for the round tube to pass through between the two transmission rollers 23, so as to meet the flaw detection of round tubes of different sizes.

[0024] like Figure 3 As shown, a lead screw 28 is rotatably connected to the middle of one end of the U-shaped plate 22 via a bearing. The lead screw 28 passes through the square shell 21 and is threadedly connected to the square shell 21. A handle 29 is fixedly connected to one end of the lead screw 28.

[0025] According to the above structure, when adjusting the position of the U-shaped plate 22, the screw 28 is rotated by the handle 29 to adjust the position of the U-shaped plate 22 up and down. The sliding grooves 24 on both sides of the U-shaped plate 22 slide inside the corresponding sliding grooves 24, thereby improving the stability of the U-shaped plate 22 when sliding.

[0026] like Figure 4 As shown, the detection component 3 includes a polygonal hole 32 fixedly connected to the top of the substrate 1, and a camera 33 equidistantly distributed around the axis of the circular plate 31 on the side wall of the polygonal hole 32.

[0027] According to the above structure, during the inspection, the camera 33 is electrically connected to the computer terminal of the peripheral device. When the round tube passes through the camera 33 during the inspection, the camera 33 takes a picture of the round tube and transmits the captured image to the computer terminal. The computer processes the image and identifies the rust and dents on the surface of the round tube. Based on the damage detected by the corresponding camera 33, the location of the damage can be quickly located.

[0028] The working principle of this utility model is as follows: In use, the round tube passes between the two transmission rollers 23 of the transmission component 2. The reduction motor 26 drives one of the transmission rollers 23 to rotate, thereby driving the round tube forward. When the round tube passes through the detection component 3, the detection component 3 will detect the round tube, thereby performing flaw detection. In use, the distance between the two transmission rollers 23 can be adjusted by sliding the two U-shaped plates 22 to accommodate round tubes of different diameters. The arc-shaped protrusion 27 is set to provide space for the round tube to pass between the two transmission rollers 23, satisfying the flaw detection of round tubes of different sizes. When the U-shaped plate 22 is in position, the screw 28 is rotated by the handle 29 to adjust its position up and down. The sliding grooves 24 on both sides of the U-shaped plate 22 slide inside the corresponding grooves 24, thereby improving the stability of the U-shaped plate 22 when sliding. During the inspection, the camera 33 is electrically connected to the computer terminal of the peripheral device. When the round tube passes through the camera 33 during the inspection, the camera 33 takes a picture of the round tube and transmits the captured image to the computer terminal. The computer processes the image and identifies rust and dents on the surface of the round tube. Based on the damage detected by the corresponding camera 33, the location of the damage can be quickly located.

[0029] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
