Description

Technical Field

[0001] This utility model relates to the field of pipeline cleaning technology, specifically to a device for detecting lint and debris in pipelines. Background Technology

[0002] Pickling and passivation is a chemical reaction used to remove rust and corrosion from steel surfaces, as well as various types of oil, rust, scale, weld spots, and other contaminants. After treatment, the surface becomes a uniform silver-white color, greatly improving the corrosion resistance of stainless steel. It is suitable for various types of stainless steel parts, plates, and equipment.

[0003] The inner wall of the stainless steel pipe is pickled and passivated, and after cleaning and drying, the cleaning effect is tested for lint. Currently, only ultraviolet light is used to test the inner wall at the pipe opening, and it is not possible to test the inner wall in the middle and deep inside of the pipe. Utility Model Content

[0032] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of the invention. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

They are used only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0034] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0035] like Figures 1-3 As shown, this utility model discloses a device for detecting lint in pipes, including a support part and a detection part. The support part sends the detection part into the pipe, and the detection part detects the inside of the pipe.

[0036] The support unit includes a support rod 1, one end of which is connected to a cuboid support 3. An extension assembly is movably connected to the end of the support rod 1 away from the support 3, and the length of the extension assembly is adjustable. The extension assembly includes multiple extension rods 2, each with the same outer diameter as the support rod 1. Both ends of the extension rod 2 are coaxially provided with threaded grooves and threaded rods. The end of the support rod 1 away from the support 3 is also coaxially provided with a threaded groove. Multiple extension rods 2 can be sequentially threaded to the end of the support rod 1 away from the support 3. The number of extension rods 2 is selected according to the length of the pipe, allowing the detection unit to completely detect the depth of the pipe.

[0037] The support unit also includes a guide assembly, which guides the support rod 1 and multiple extension rods 2, allowing them to slide axially into the pipe. The guide assembly also provides support, especially when there are many extension rods 2. This support prevents operators from exerting excessive force, causing fatigue or hand tremors, and thus avoiding interference with pipe inspection operations. The number of guide assemblies can be adjusted; two or more can be placed at the pipe opening as needed.

[0038] The guiding assembly includes an annular guide ring 7, the inner diameter of which is not less than the outer diameter of the support rod 1 and the extension rod 2. Multiple universal balls 12 are evenly rotatably arranged on the inner circumference of the guide ring 7. Four support rods are arranged radially on the outer circumferential wall of the guide ring 7, with equal spacing between them. The ends of the support rods furthest from the guide ring 7 are provided with rubber ball heads 10.

[0039] The support rod includes a fixed rod 9, which is connected to the outer circumference of the guide ring 7. The outer wall of the fixed rod 9 has an external thread. A movable cylinder 8 is fitted onto the fixed rod 9, and the inner wall of the movable cylinder 8 has an internal thread that mates with the external thread. The movable cylinder 8 is threadedly engaged with the fixed rod 9. A ball head 10 is located at the end of the movable cylinder 8 furthest from the guide ring 7. By rotating the movable cylinder 8 on the fixed rod 9, the length of the support rod can be adjusted to match the inner diameter of the pipe.

[0040] The testing unit includes four sets of testing components mounted on the support 3. The four sets of testing components are arranged on the four sides of the support 3, and each set of testing components tests one-quarter of the pipe cross-section.

[0041] The detection assembly includes a detection cover 4 mounted on a support 3. The detection cover 4 is made of opaque polypropylene material. The detection cover 4 is frustum-shaped and its smaller diameter end is connected to the support 3. An ultraviolet lamp 6 is mounted on the support 3 inside the detection cover 4. The ultraviolet lamp 6 is annular and coaxial with the detection cover 4. A camera 5 is mounted on the support 3 at the center of the inner side of the ultraviolet lamp 6.

[0042] The support 3 is equipped with wiring that is electrically connected to the cameras 5 and ultraviolet lamps 6 of the four detection components. The wiring extends from the side wall where the support 3 is connected to the support rod 1. The detection unit also includes a control box 11 that is electrically connected to the wiring. The control box 11 contains a power supply and control circuit that is electrically connected to the wiring. The control box 11 is equipped with a display screen and buttons that display the images captured by the four cameras 5.

[0043] During the inspection, the support rod 1 is first passed through the guide ring 7, and then the guide ring 7 is placed into the pipe opening. By rotating the movable cylinder 8, the position of the movable cylinder 8 on the fixed rod 9 is adjusted, thereby adjusting the length of the support rod so that the guide ring 7 is in the center of the pipe, and the ball head 10 at the end of the support rod is pressed against the inner wall of the pipe, thus fixing the guide assembly. Then, the camera 5 and ultraviolet light 6 of the inspection unit are turned on, and the support rod 1 is extended into the pipe to inspect the inner wall of the pipe. The image captured by the camera 5 is transmitted to the display screen. As the support rod 1 is extended, an extension rod 2 is added to the end of the support rod 1. The number of extension rods 2 added is based on the length of the pipe, achieving a complete inspection of the inside of the pipe.

[0044] The above embodiments are merely preferred embodiments of this utility model and are not intended to limit the technical solutions of this utility model. Any technical solution that can be implemented based on the above embodiments without creative effort should be considered to fall within the scope of protection of this utility model patent.
