Description

Technical Field

[0001] This utility model relates to the field of water supply pipeline flaw detection technology, and in particular to a self-cleaning industrial pipeline inner wall flaw detection device. Background Technology

[0002] Industrial water supply pipelines are important infrastructure to ensure normal production operations. Their long-term underground or overhead operation makes them prone to defects such as cracks and leaks due to corrosion, wear, and pressure shock. If these defects are not detected in time, they may cause serious problems such as water outages and pollution.

[0003] Traditional pipeline inspection methods have significant shortcomings: manual inspection requires excavation or dismantling of pipelines, which is not only time-consuming, labor-intensive, and costly, but also affects normal water supply; although some pipeline robots can achieve trenchless inspection, they generally suffer from functional disconnect—they lack effective cleaning mechanisms, and scale, rust, and other deposits on the inner walls of pipelines can obstruct the inspection lens, leading to missed defects; the lighting system and inspection lens are not well coordinated, making it difficult to obtain clear images in dimly lit pipeline environments, which affects the accuracy of inspection.

[0004] To address this, a self-cleaning industrial pipeline internal wall flaw detection device is proposed. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0034] Reference Figures 1-4 This utility model provides a self-cleaning industrial pipeline inner wall flaw detection device, comprising:

[0035] The housing 1 has an underwater camera 2 mounted on one end, and a control system is installed inside the housing 1; the control system uses a microcontroller or PLC.

[0036] A transparent cover 3 is detachably connected to one end of the outer shell 1 and covers the underwater camera 2.

[0037] Lighting components are mounted on the inner wall of the transparent housing 3;

[0038] A drive assembly is installed inside the housing 1. A cleaning wheel assembly is installed at the output end of the drive assembly. The cleaning wheel assembly extends out of the housing 1 and is located at the end of the housing 1 away from the underwater camera 2. The cleaning wheel assembly is in contact with the inner wall of the water supply pipe.

[0039] Automatic walking wheel assembly, the automatic walking wheel assembly is provided in several groups, the several groups of automatic walking wheel assemblies are circumferentially installed on the outer wall of the housing 1, and the automatic walking wheel assembly is in contact with the inner wall of the water supply pipe;

[0040] Among them, the underwater camera 2, lighting components, drive components and several sets of walking wheel components are all electrically connected to the control system;

[0041] With this configuration, the underwater camera 2 is encased in a transparent housing 3, preventing impurities from directly contaminating the lens. An illumination component installed on the inner wall of the transparent housing 3 allows for uniform illumination of the pipe's inner wall, forming a clear imaging system with the underwater camera 2. This system can accurately capture details of defects such as cracks and corrosion. The drive component moves the cleaning wheel component to clean scale and impurities from the pipe's inner wall before inspection, ensuring an unobstructed view for the camera and reducing the risk of missed detections. This improves the flaw detection accuracy of water supply pipelines and allows for stable operation even in dark, impurity-laden industrial pipelines, providing reliable inspection assurance for the safe operation of industrial water supply pipelines.

[0042] This invention features several sets of automatic walking wheel assemblies circumferentially mounted on the outer wall of the outer casing 1, which are in close contact with the inner wall of the water supply pipe, thus improving the walking stability of the device. The cleaning wheel assembly operates synchronously with the walking function, eliminating the need for manual cleaning of the pipe in advance and saving preparation time. The underwater camera 2 collects images in real time and transmits them to the control system, enabling simultaneous walking and inspection. Flaw detection can be completed without stopping the water supply, significantly shortening the inspection cycle and reducing the impact on industrial production.

[0043] The solution has been further optimized, and the automatic walking wheel assembly includes:

[0044] Support 4, one end of which is fixedly connected to the outer wall of the outer casing 1;

[0045] A rotating shaft 5 is rotatably connected to the end of the bracket 4 away from the outer casing 1. Two walking wheel bodies 6 are respectively installed on both sides of the rotating shaft 5, and the walking wheel bodies 6 are in contact with the inner wall of the water supply pipe.

[0046] The drive unit is mounted on the bracket 4. The output shaft of the drive unit is connected to the rotating shaft 5 for transmission. The drive unit is electrically connected to the control system.

[0047] The further optimized scheme includes a first motor 7 mounted on a bracket 4, a first bevel gear 8 mounted on the output shaft of the first motor 7, a second bevel gear 9 mounted on the rotating shaft 5, the first bevel gear 8 and the second bevel gear 9 meshing and transmitting power, the first motor 7 being electrically connected to the control system, and the first motor 7, the first bevel gear 8 and the second bevel gear 9 being covered by a waterproof cover 10.

[0048] One end of the bracket 4 is fixed to the outer wall of the housing 1, providing support for the entire assembly. The rotating shaft 5 is rotatably connected to the end of the bracket 4 furthest from the housing 1, with the wheel bodies 6 on both sides contacting the inner wall of the water supply pipe. The first motor 7 is mounted on the bracket 4 and electrically connected to the control system, providing power to the wheel bodies. After the first motor 7 starts, its output shaft drives the first bevel gear 8 to rotate. Since the first bevel gear 8 meshes with the second bevel gear 9 on the rotating shaft 5, power is transmitted to the rotating shaft 5 through gear transmission, driving the wheel bodies 6 to rotate. The waterproof cover 10 covers the first motor 7, the first bevel gear 8, and the second bevel gear 9, effectively preventing water and impurities from entering the pipe, protecting the drive components, and ensuring their stable operation.

[0049] In a further optimized design, the drive assembly includes a second motor 11 mounted on the inner wall of the housing 1. The second motor 11 is electrically connected to the control system. The output shaft of the second motor 11 is mounted with a drive shaft 12 via a coupling. The end of the drive shaft 12 extends out of the housing 1 and is fixedly connected to the cleaning wheel assembly.

[0050] Further optimization of the solution: the cleaning wheel assembly includes a cleaning wheel body 13 fixedly mounted on the drive shaft 12, and a number of cleaning brushes 14 are installed on the outer side wall of the cleaning wheel body 13. The number of cleaning brushes 14 are arranged at equal intervals around the circumference, and the cleaning brushes 14 are in contact with the inner wall of the water supply pipe.

[0051] The second motor 11 is mounted on the inner wall of the housing 1 and is controlled by the control system. When the second motor 11 starts, its output shaft drives the drive shaft 12 to rotate via a coupling. The end of the drive shaft 12 extends out of the housing 1 and is fixedly connected to the cleaning wheel assembly, thereby driving the cleaning wheel body 13 to rotate. Several cleaning brushes 14 arranged circumferentially at equal intervals on the outer wall of the cleaning wheel body 13 contact the inner wall of the water supply pipe. During rotation, the cleaning brushes 14 can clean the scale and impurities on the inner wall of the pipe. This structure ensures uniform cleaning range, improves cleaning effect, and provides a clear field of view for the flaw detection work of the underwater camera 2.

[0052] Further optimization of the design includes a lighting assembly comprising several lighting lamps 15, which are equally spaced and mounted on the inner wall of the transparent housing 3. Each of the lighting lamps 15 is electrically connected to the control system. The control system can control the activation, deactivation, and brightness of the lighting lamps 15. When the device is operating, the lighting lamps 15 illuminate, and light is evenly distributed from inside the transparent housing 3 onto the inner wall of the pipe, providing sufficient light for the underwater camera 2. This ensures that the underwater camera 2 can clearly capture details of defects on the inner wall of the pipe, improving the accuracy of flaw detection.

[0053] The design was further optimized by installing a laser locator and a miniature inkjet marker at the front end of the outer casing 1, which are linked with the underwater camera 2 and the control system. When the underwater camera 2 detects a pipeline defect, the laser locator emits a laser to mark the defect location, and the miniature inkjet marker sprays water-soluble fluorescent ink as a temporary mark. The control system simultaneously records the three-dimensional coordinates of the defect (combined with the device's travel distance and angle sensor data), facilitating rapid location by subsequent maintenance personnel and improving defect handling efficiency.

[0054] A further optimized design includes a connecting frame 16 installed inside the outer casing 1. Several brackets 4, with their ends furthest from the rotating shaft 5, extend into the outer casing 1 and are fixedly connected to the connecting frame 16. The connecting frame 16 connects multiple brackets 4 into a single unit, enhancing the stability and robustness of the connection between the brackets 4 and the outer casing 1. This makes the automatic walking wheel assembly more stable during device movement, reducing the impact of vibration and other factors on the detection process.

[0055] To further optimize the design, anti-slip grooves are provided on the outer wall of the walking wheel body 6. These grooves increase the friction between the walking wheel body 6 and the inner wall of the water supply pipe. This effectively prevents the walking wheel body 6 from slipping when the device moves along the pipe, especially when the inner wall of the pipe is damp or has a certain slope, ensuring the stability of the device's movement and the accuracy of the detection path.

[0056] To further optimize the design, an electric telescopic rod is added to the connection between the bracket 4 and the outer shell 1. The telescopic rod is electrically connected to the control system. After the device enters the pipeline, the control system uses the image of the pipeline's inner diameter captured by the underwater camera 2 to drive the electric telescopic rod to extend and retract, adjusting the distance between the walking wheel body 6 and the outer shell 1. This ensures that the automatic walking wheel assembly is always in close contact with the inner wall of pipelines of different diameters, expanding the device's applicability.
