[0002] In industrial production, municipal engineering and other fields, pipelines are important infrastructure for transporting fluids, and their safe and stable operation is crucial. During long-term use, pipelines are prone to damage such as cracks, corrosion pits and wear on the outer wall due to factors such as medium corrosion, mechanical wear and external pressure. If these damages are not detected in time, they may lead to serious safety accidents such as leaks and explosions, causing huge economic losses and environmental pollution.

[0003] Traditional methods for detecting pipeline damage still have shortcomings. Some detection devices have poor versatility and are difficult to adapt to pipelines of different widths and volumes. They cannot accurately position and stably clamp the pipeline during detection. Specialized clamps need to be frequently changed for pipelines of different volumes, which not only increases the cost of equipment procurement and maintenance, but also prolongs the preparation time before detection and reduces the detection efficiency. Therefore, this application provides a detection device for buried steel pipeline damage to meet the needs. Utility Model Content

Detailed Implementation

[0028] The following is a detailed description of a device for detecting damage to buried steel pipelines provided by this utility model, with reference to the accompanying drawings and specific embodiments. It should be noted that, to make the embodiments more detailed, the following embodiments are the best and preferred embodiments; those skilled in the art can also use other alternative methods to implement some known technologies. Furthermore, the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit this utility model.

[0029] like Figures 1-7As shown, an embodiment of this utility model provides a detection device for damage to buried steel pipelines, including an operating table 1, on which a damage detection device 2 is installed for detecting damage to the outside of the pipeline.

[0030] Specifically, the detection device 2 includes a first slider 201, which is arc-shaped and works in conjunction with a first sliding groove 202 on the surface of the operating table 1. The first slider 201 can slide within the first sliding groove 202. A first spring 203 is fixedly connected to the inner wall of the first sliding groove 202. One end of the spring is connected to the first slider 201. When the first slider 201 is subjected to external force and slides within the first sliding groove 202, the first spring 203 plays a role in buffering and resetting, enabling the first slider 201 to adapt to the irregular shape of the pipe surface during the detection process and always maintain good contact with the outer wall of the pipe, thus ensuring the accuracy and stability of the detection.

[0031] A housing 205 is fixedly installed on the side of the first slider 201 near the first slot 204. A sensor 209 is installed inside the housing 205. A sleeve 206 is fixedly connected to the inner wall of the housing 205, and a second spring 207 is fixedly connected to the inner wall of the sleeve 206. One end of the second spring 207 is connected to a sliding rod 208, which can slide on the inner wall of the sleeve 206, allowing it to adaptively adjust to the surface undulations of the pipe during detection. A sensor 209, an eddy current sensor 209, is installed at the end of the sliding rod 208 away from the sleeve 206. The sensor 209 is a MiYi eddyNCDT. The 3301 series, specifically the 209 eddy current sensor, boasts high accuracy and stability, adaptability to various industrial environments, a measurement range of up to 50mm, and good linearity. It can accurately detect minute damage to pipe surfaces. The 209 eddy current sensor utilizes the principle of electromagnetic induction. When an alternating current flows through the coil of the 209 sensor, an alternating magnetic field is generated around it. If there are cracks, corrosion pits, or other damage on the outer wall of the pipe, it will cause changes in the electromagnetic properties of the pipe surface, such as conductivity and permeability, thereby altering the induced current in the coil of the 209 sensor. This change in current is detected to determine whether there is damage to the outer wall of the pipe. This is a conventional technical method and will not be elaborated upon further here.

[0032] A detachable protective strip 210 is designed at the end of the slide rod 208 near the sensor 209. The protective strip 210 is inclined and its function is to protect the sensor 209 during the detection process, preventing damage caused by direct friction or collision between the sensor 209 and the pipe surface. It also avoids interference from impurities and debris on the pipe surface during the detection process, ensuring the accuracy of the detection results. A insertion slot 401 is provided on the side of the slide rod 208 near the sensor 209, into which the protective strip 210 can be directly inserted for quick installation. A bolt 402 is threadedly connected to the outer wall of the slide rod 208. The bolt 402 passes through the slide rod 208 and is threadedly connected to the protective strip 210. This double fixing method ensures the stability of the protective strip 210 during the detection process and prevents it from falling off.

[0033] Furthermore, a positioning component 3 for positioning the pipeline during inspection is also installed on the operating table 1. The positioning component 3 includes a second sliding groove 301, and a third spring 302 is fixedly connected to the inner wall of the second sliding groove 301. One end of the third spring 302 is connected to a second slider 303. The second slider 303 is also arc-shaped and can slide within the second sliding groove 301. The third spring 302 provides elastic support for the second slider 303, enabling it to closely fit the pipeline surface during inspection and play a positioning role. This ensures that the position of the inspection device 2 on the pipeline is stable and avoids affecting the inspection results due to positional deviation.

[0034] The second slider 303 has an installation groove 304, in which a cleaning pad 305 is slidably mounted. Before inspecting the pipeline, the cleaning pad 305 can clean the pipeline surface, removing dust, oil, and other impurities, thus improving the accuracy of the inspection. A sliding groove 306 is provided on one side of the second slider 303, and a fourth spring 307 is fixedly connected to the inner wall of the sliding groove 306. One end of the fourth spring 307 is connected to a limiting block 308. A limiting groove 309 is provided on the side of the cleaning pad 305 near the limiting block 308. The limiting block 308 and the limiting groove 309 are inserted into each other. When it is necessary to replace the cleaning pad 305... At 05:00, simply press the limiting block 308 gently to disengage it from the limiting groove 309, overcoming the elastic force of the fourth spring 307, and the cleaning pad 305 can be removed from the mounting groove 304. When installing a new cleaning pad 305, place it into the mounting groove 304, and the limiting block 308 will automatically insert into the limiting groove 309 under the action of the fourth spring 307, achieving quick installation and fixation. In addition, the limiting block 308 has anti-slip texture, which increases the friction between the limiting block 308 and the limiting groove 309, further improving the stability of the cleaning pad 305 installation and preventing it from falling off during cleaning.

[0035] When it is necessary to inspect the outer wall of the pipe for damage, the two second sliders 303 are slid to move away from each other according to the width and volume of the pipe. This process compresses the third spring 302. After adjusting to the appropriate position, the pipe is placed between the two second sliders 303. Subsequently, the second spring 207 returns to its original shape and pushes the second sliders 303 closer together to precisely limit and clamp the pipe. After clamping, the pipe is pushed to slide towards the sensor 209. The cleaning cotton pad 305 inside the second slider 303 simultaneously cleans the outer wall of the pipe, effectively removing dust and avoiding impurities from affecting the detection accuracy, thus achieving simultaneous detection and cleaning.

[0036] When the cleaning pad 305 needs to be replaced, slide the limit block 308 to disengage it from the limit groove 309. This operation will compress the fourth spring 307. After the limit block 308 is disengaged, the old cleaning pad 305 can be taken out from the mounting groove 304. Then, install the new cleaning pad 305 into the slide groove 306, release the limit block 308, and the fourth spring 307 will return to its original shape, pushing the limit block 308 to re-engage with the limit groove 309, thus completing the quick replacement of the cleaning pad 305.

[0037] After cleaning, the pipeline enters the detection device 2. By sliding the first slider 201 and compressing the first spring 203, the pipeline is clamped and fixed for a second time. When the outer wall of the first slider 201 is tightly attached to the pipeline, the pipeline continues to move towards the detection device 2. When the pipeline contacts the inclined protective strip 210, the outer wall will squeeze the protective strip 210. This squeezing force is transmitted to the slide rod 208 through the protective strip 210. After the slide rod 208 is stressed, it drives the protective strip 210 and the sensor 209 to slide along the inner wall of the sleeve 206, while compressing the second spring 207. As the pipeline continues to move, the protective strip 210 slides along the outer wall of the pipeline. The second spring 207 returns to its original shape and pushes the slide rod 208 to reset. At this time, the sensor 209 completes the damage detection of the outer wall of the pipeline between the two protective strips 210. This design can not only adapt to the detection needs of pipelines of different sizes, but also reduce the direct contact between the sensor 209 and the pipeline through the protective strip 210, effectively protecting the sensor 209.

[0038] If the protective strip 210 needs to be replaced, simply remove the bolt 402 on the slide bar 208, pull out the old protective strip 210 from the insertion slot 401, insert the new protective strip 210, and then tighten the bolt 402 again. The operation is simple and quick.

To provide the public with a thorough understanding of this utility model, specific details have been described in detail in the above preferred embodiments; however, those skilled in the art can fully understand this utility model even without these detailed descriptions.

[0040] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
