Description

Technical Field

[0001] This utility model relates to the field of cleaning device technology, and in particular to an automatic cleaning device for pipelines. Background Technology

[0002] Pipeline cleaning refers to the cleaning of the inside of pipelines to prevent scaling, blockage, or corrosion on the inner walls. This process aims to restore the normal function of the pipeline, extend its service life, and ensure the safety and efficiency of fluid transportation. Pipeline cleaning can be categorized into the following main methods based on the tools and techniques used: Chemical cleaning: Dissolving scale inside the pipeline with chemical agents, followed by cleaning using a circulating pump station. This method is suitable for pipelines with complex shapes, providing thorough cleaning quickly. High-pressure water cleaning: Using high-pressure water flow (typically above 50 MPa) to remove scale from the inner walls of the pipeline. This method is suitable for short-distance, large-diameter pipelines, offering speed and low cost. Pipeline pigging technology: Using a pipeline pig (PIG) ​​moving inside the pipeline to remove accumulated scale. This method is particularly suitable for cleaning long-distance pipelines, such as oilfield pipelines. Mechanical scraping: Placing mechanical scrapers or other tools inside the pipeline to remove attached scale. This method is commonly used for cleaning oil transportation pipelines.

[0003] In some existing mechanical cleaning equipment, the scraper of the cleaning device has poor adhesion to the inner wall of the pipe, making it difficult to adapt to pipes of different inner diameters or subtle changes in the inner wall of the pipe. During the cleaning process, gaps can easily form between the scraper and the inner wall due to fluctuations in the inner diameter of the pipe or the shaking of the device itself, resulting in incomplete cleaning. Residual impurities will still affect the normal use of the pipe. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Example 1

[0025] Reference Figure 1 and Figure 2 An automatic cleaning device for pipes includes a connecting rod 1, a first mounting block 2 on one side of the connecting rod 1, two mounting grooves 3 on the outer periphery of the connecting rod 1, a bracket 4 in each of the two mounting grooves 3, and a mounting plate 5 rotatably mounted on each of the brackets 4.

[0026] A scraper 6 is installed on one side of the mounting plate 5. The scraper 6 is used to clean the pipe by adhering to the inner wall of the pipe.

[0027] An elastic limiting component is provided on one side of the mounting groove 3 to apply elastic force to the mounting plate 5 so that the scraper 6 on one side of the mounting plate 5 fits against the inner wall of the pipe.

[0028] In use, this device uses a connecting rod 1 with two mounting slots 3 on its outer circumference. Each mounting slot 3 contains a bracket 4, and a mounting plate 5 is rotatably mounted on each bracket 4. A scraper 6 is mounted on one side of the mounting plate 5. The scraper 6 is tightly fitted against the inner wall of the pipe to clean the pipe. An elastic limiting component is provided, with one end connected to one side of the mounting plate 5 to restrict the rotation of the mounting plate 5. This ensures that the scraper 6 on one side of the mounting plate can always be in contact with the inner wall of the pipe, ensuring a stable and reliable cleaning process.

[0029] Furthermore, the scraper 6 is arc-shaped, and the arc-shaped end of the scraper 6 extends from one side of the mounting plate 5 toward the first mounting block 2. The scraper 6 and the mounting plate 5 are integrally formed. The arc-shaped design can better adapt to the curvature of the inner wall of the pipe, increase the contact area with the inner wall of the pipe, and improve cleaning efficiency. The integrally formed structure enhances the connection strength between the scraper 6 and the mounting plate 5, reduces the possibility of component loosening, and extends the service life of the device.

[0030] Furthermore, the elastic limiting component includes a first mounting rod 7 disposed on the inner wall of the mounting groove 3 and a second mounting rod 8 disposed on one side of the mounting plate 5. A hook spring 9 is disposed between the first mounting rod 7 and the second mounting rod 8. The two ends of the hook spring 9 are respectively connected to the first mounting rod 7 and the second mounting rod 8. The elastic limiting component adopts a combination of the first mounting rod 7, the second mounting rod 8 and the hook spring 9, which has a simple structure and is easy to install and maintain. The hook spring 9 can provide a stable elastic force, effectively limiting the rotation of the mounting plate 5 and ensuring the fit between the scraper 6 and the inner wall of the pipe.

[0031] Furthermore, the hook spring 9 extends obliquely outward from one end of the second mounting rod 8 and connects to the first mounting rod 7. The elastic force of the hook spring 9 can apply elastic force to the second mounting rod 8 to drive the mounting plate 5 to rotate, so that one end of the mounting plate 5 is in contact with the inner wall of the mounting groove 3. The elastic force generated by the oblique setting of the hook spring 9 can stably squeeze the second mounting rod 8, drive the mounting plate 5 to rotate and make one end of the mounting plate 5 in contact with the inner wall of the mounting groove 3, thereby ensuring that the scraper 6 is in close contact with the inner wall of the pipe, making the transmission of elastic force more direct and efficient, further improving the reliability of the scraper 6's contact, and ensuring the smooth progress of the cleaning work.

[0032] Furthermore, a sealing element 10 is installed on the outer periphery of the first mounting block 2, which fits against the inner wall of the pipe. The outer periphery of the sealing element 10 is provided with a groove 11, and a plurality of cleaning elements 12 are provided in the groove 11. The sealing element 10 on the outer periphery of the first mounting block 2 fits against the inner wall of the pipe, which can reduce the leakage and backflow of impurities during the cleaning process and enhance the sealing of the cleaning environment. The cleaning elements 12 remove a certain amount of deposits with sufficient rigidity, but cannot remove hard or thick deposits.

[0033] Furthermore, the sealing element 10 and the cleaning element 12 are integrally formed, and both the sealing element 10 and the cleaning element 12 are made of rubber. The integral structure of the sealing element 10 and the cleaning element 12 improves the firmness of the connection between the two and avoids the problem of component separation. The rubber material has good elasticity and wear resistance, which can not only ensure the tight fit between the sealing element 10 and the inner wall of the pipe, but also allow the cleaning element 12 to better adapt to the inner wall of the pipe during the cleaning process, while extending the service life of the sealing element 10 and the cleaning element 12.

[0034] Furthermore, the mounting plate 5 is horizontal on the side closest to the inner wall of the mounting groove 3, and the mounting block is horizontal on the side closest to the inner wall of the mounting groove 3, so that it can fit tightly against the inner wall of the mounting groove 3, which enhances the stability of the mounting block in the mounting groove 3, reduces shaking during the cleaning process, ensures the stability of components such as the scraper 6, and thus improves the cleaning effect.

[0035] Furthermore, the first mounting block 2 is shaped like a frustum, which reduces the resistance it encounters when moving within the pipeline, facilitating smooth movement of the device within the pipeline. At the same time, the frustum-shaped structure can better cooperate with components such as the sealing element 10, improving the overall structural rationality and operational stability.

[0036] Example 2

[0037] Reference Figure 3 and Figure 4 The connecting rod 1 has a socket 13 at its end away from the first mounting block 2. A plug 14 is disposed within the socket 13. A second mounting block 15 is disposed on one side of the plug 14. By installing another connecting rod 1 on the other side of the second mounting block 15, the scrapers 6 on the two connecting rods 1 can be staggered to expand the cleaning range inside the pipe. The connecting rod 1 connects to the second mounting block 15 through the cooperation of the socket 13 and the plug 14. This detachable connection method facilitates the flexible assembly of multiple connecting rods 1 according to pipe cleaning needs. When another connecting rod 1 is installed on the other side of the second mounting block 15, the scrapers 6 on the two connecting rods 1 can be staggered. This effectively expands the cleaning coverage of the inside of the pipe, avoiding blind spots that exist when cleaning with a single connecting rod 1 and scraper 6. The staggered scraper 6 can clean the inner wall of the pipe from different angles, improving the thoroughness of the cleaning. It is especially suitable for cleaning long pipes or pipes with little change in inner diameter, enhancing the practicality and applicability of the device. In addition, a bolt (not shown in the figure) can be installed through the connecting rod 1 from one side of the mounting groove 3. The bolt abuts against the insert 14 in the socket 13, restricting the insert 14 within the socket 13. This connection structure is simple and stable, ensuring stable cooperation of multiple connecting rods 1 during the cleaning process and ensuring the smooth progress of the cleaning work.

[0038] Additionally, it should be noted that the two embodiments of this application can clean the pipe by inserting the application into one end of the pipe and exiting from the other end.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
