Description

Technical Field

[0001] This invention relates to the field of water conservancy engineering technology, specifically to a pneumatic self-propelled water conservancy engineering pipeline positioning and detection device. Background Technology

[0002] With the accelerating pace of urbanization and the increasing demand for urban transportation, the construction and maintenance of road systems in urban areas such as roads, highways, stations, and airports have become a key focus of urban development. Double-wall corrugated pipes are a common type of road surface pipeline, ensuring the smooth flow and safety of numerous underground pipelines. However, due to their long service life, these pipes frequently suffer damage, leading to ruptures and leaks, threatening transportation safety. To avoid the impact of road excavation and construction on traffic, trenchless pipeline repair technology has emerged. Trenchless repair of double-wall corrugated pipes under the road surface is one such common solution. This method uses camera technology to detect the location of pipeline damage and then repairs the pipe using non-destructive techniques, thus achieving pipeline maintenance and renewal. The specific steps are as follows: High-definition camera technology is used to observe and detect the inner and outer walls of the double-wall corrugated pipe. By observing the images inside the pipe, the location and condition of the damage are identified, and pipeline repair techniques are then applied. Mechanical repair of pipelines typically utilizes fiberglass reinforced materials to repair double-wall corrugated pipes. This material boasts advantages such as high strength, corrosion resistance, and aging resistance, effectively reinforcing the pipeline structure and preventing damage. The trenchless repair method for double-wall corrugated pipes under road surfaces is suitable for the repair and replacement of pipelines in various road surfaces, including urban roads, highways, stations, and airports. Compared to traditional open-cut pipeline repair methods, the trenchless repair method offers the following advantages: First, it eliminates the need to excavate both the pipeline and the road surface, reducing the need to open existing hardened surfaces, avoiding the impact of road excavation on transportation and the damage to the surrounding environment, and lowering construction costs. Second, the trenchless repair method combines advanced pipeline imaging technology with repair machinery, enabling rapid and accurate location of pipeline damage and quick repair, significantly improving construction efficiency. Furthermore, the trenchless repair method avoids the impact of excavation on surrounding buildings and facilities, reducing safety hazards and ensuring construction safety. This repair method is also an efficient repair method for water conservancy pipelines located underground and underwater. However, due to the special nature of water conservancy pipelines, the break point is usually located far from the inspection port. At this time, traditional pipeline repair machinery is affected by the internal environment of the pipeline during repair, and cannot treat the dirt on the inner wall of the pipeline or grind the break point. As a result, the firmness and effect of the repair cannot be guaranteed after the repair is completed. Summary of the Invention

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

[0027] Please see Figure 1-10 The present invention provides a technical solution: a pneumatic self-propelled water conservancy engineering pipeline positioning and detection device.

[0028] Example 1

[0029] This embodiment discloses: an operating vehicle 1, a computer 2 is provided on top of the operating vehicle 1, and a rotating take-up roller 3 is installed inside the operating vehicle 1. An air pipe 5 is wound around the surface of the take-up roller 3. The operating vehicle 1 is placed on one side of the water conservancy pipeline 4, and a traveling vehicle 6 is placed inside the water conservancy pipeline 4. A rotating traveling wheel 7 is installed on the lower side surface of the traveling vehicle 6. A connector 8 is fixedly provided on one side outer surface of the traveling vehicle 6, and the traveling vehicle 6 is fixedly connected to the air pipe 5 through the connector 8. A drive mechanism is provided on the traveling vehicle 6, which enables the traveling vehicle 6 to move and clean the inner wall of the water conservancy pipeline 4. The drive mechanism includes: an air passage 9, which is located inside the upper end of the traveling vehicle 6. A rotating drive impeller 10 is installed inside the air passage 9. A drive wheel 11 is fixedly connected to the lower end of the shaft of the drive impeller 10. A driven wheel 12 is fixedly installed on the outer surface of one end of the shaft of the traveling wheel 7 inside the traveling vehicle 6. A connecting pipe 13 is fixedly installed on one side surface of the traveling vehicle 6. A bearing pipe 14 is fixedly installed on one side surface of the connecting pipe 13. An exhaust hole 15 is opened on the side surface of the bearing pipe 14. A rotating cleaning disc 16 is installed at one end of the bearing pipe 14. The shaft of the cleaning disc 16 passes through the bearing pipe 14. A rotating impeller 17 is fixedly installed at one end of the shaft of the cleaning disc 16 inside the bearing pipe 14. A rotating rod 18 is installed on the side surface of the cleaning disc 16. A cleaning brush 19 is fixedly installed on the outer surface of one end of the rod 18. The drive impeller 10 and the air passage 9 are tangentially arranged, and one end of the air passage 9 passes through the side surface of one end of the traveling vehicle 6 where the connecting pipe 13 is located. The drive impeller 10 is connected to the driven wheel 12 through the drive wheel 11, and the driven wheel 12 and the traveling wheel 7 are concentrically arranged. The rotating rod 18 is evenly distributed on the side surface of the cleaning disc 16, and the rotating rod 18 is in contact with the inner surface of the water pipe 4 through the cleaning brush 19. When the traveling vehicle 6 needs to move inside the water pipe 4, the computer 2 placed on the upper end of the operating vehicle 1 controls the externally installed air pump to start. The air pump injects air into the air passage 9 through the air pipe 5 and the connector 8. When the gas moves inside the air passage 9, it drives the drive impeller 10 to rotate. The drive impeller 10 drives the traveling wheel 7 to rotate through the meshing of the drive wheel 11 and the driven wheel 12. At this time, the traveling wheel 7 drives the traveling vehicle 6 to move by contacting the inner wall of the water pipe 4. During the process, the take-up roller 3 is driven to rotate to unwind the air pipe 5. During the movement of the traveling vehicle 6, the air discharged from the air passage 9 drives the rotating impeller 17 to rotate through the connecting pipe 13 and the bearing pipe 14 and is discharged through the exhaust hole 15. At this time, the rotating impeller 17 drives the cleaning disc 16 to rotate. The cleaning disc 16 causes the rotating rod 18 to rotate through centrifugal force and uses the cleaning brush 19 to scrape and clean the dirt on the inner wall of the water pipe 4 that the traveling vehicle 6 passes through.

[0030] Example 2

[0031] This embodiment discloses, based on embodiment 1, that: a support mechanism is provided at the upper end of the traveling vehicle 6, and the inner wall of the water pipe 4 is wiped and cleaned through the support mechanism; The support mechanism includes: a connecting groove 22, which is located at the upper end of the air passage 9; a switching plate 23 is slidably installed on the inner surface of the traveling vehicle 6 where the connecting groove 22 is located; a switching pneumatic push rod 24 is fixedly installed on the inner surface of the traveling vehicle 6 where the connecting groove 22 is located; a pressing plate 25 is fixedly installed at one end of the switching pneumatic push rod 24; a switching groove 26 is opened on the surface of the pressing plate 25; a rotating camera 20 is installed on the upper surface of the traveling vehicle 6; an adjusting motor 21 is fixedly installed on the upper surface of the traveling vehicle 6; the output shaft of the adjusting motor 21 is fixedly connected to the camera 20; and a pressure hose 27 penetrates the upper surface of the traveling vehicle 6; a closing ring 28 is fixedly connected to the upper end of the pressure hose 27. The switching plate 23 is connected to the traveling vehicle 6 by sliding friction, and the lower end of the switching plate 23 is in contact with the inner bottom surface of the air passage 9. A spring is connected between the switching plate 23 and the inner surface of the traveling vehicle 6. One end of the extrusion plate 25 is designed to be inclined upwards, and the lower surface of the extrusion plate 25 is in contact with the inner surface of the connecting groove 22 of the traveling vehicle 6. The switching groove 26 is located directly above the connecting groove 22. The lower surface of the upwardly inclined end of the extrusion plate 25 is in contact with the upper side surface of the switching plate 23. The lower end of the pressure hose 27 is connected to the upper interior of the traveling vehicle 6, and the upper end of the pressure hose 27 is connected to the closing ring 28. A spring is connected between the inner surface of the closing ring 28 and the outer surface of the traveling vehicle 6, and a sponge material is provided on the outer surface of the closing ring 28. During the inspection, the camera 20 is rotated by the motor 21 to visually inspect the inner wall of the cleaned water pipe 4. The image is then transmitted to the computer 2 for the staff to view. When a leak is found, the take-up roller 3 drives the traveling carriage 6 to retract, allowing the closed ring 28 near the cleaning disc 16 to retract behind the leak point. At this time, the switching pneumatic push rod 24 is activated, which moves the extrusion plate 25. The extrusion plate 25 slides, causing one end of the inclined surface to press against the switching plate 23. The switching plate 23 slides down, compressing the spring between itself and the traveling carriage 6 to seal the air passage 9. At this time, the switching groove 26 moves to the position directly opposite the connecting groove 22. The gas cannot be discharged through the connecting pipe 13 but is discharged upward through the connecting groove 22 and into the upper part of the traveling carriage 6. At this time, the air passes through the pressure hose 27. Injecting the sealing ring 28 causes the sealing ring 28, which was contracted on the surface of the traveling vehicle 6 by the spring, to expand and open. At this time, the sealing ring 28 adheres to the inner surface of the water pipe 4 through the surface foam material. Then, the switching pneumatic push rod 24 is activated, which drives the extrusion plate 25 to move. The extrusion plate 25 slides so that the inclined surface at one end no longer extrudes the switching plate 23. The switching plate 23 slides upward under the support of the spring between it and the traveling vehicle 6, releasing the seal on the air passage 9. At this time, the switching groove 26 moves to a position that is misaligned with the connecting groove 22. At this time, the gas is discharged through the connecting pipe 13. At the same time, the upper end of the traveling vehicle 6 is sealed, keeping the sealing ring 28 expanded. Then, the traveling vehicle 6 is continued to move until both sealing rings 28 have moved to wipe and clean the inner wall of the leak point of the water pipe 4, so that the moisture and dirt on the inner wall of the leak point of the water pipe 4 are removed, making it easy to repair.

[0032] Example 3

[0033] This embodiment discloses, based on Embodiments 1 and 2: A repair mechanism is provided on one side of the traveling vehicle 6. The repair mechanism includes: a fixing ring 29, which is fixedly disposed at one end of the traveling vehicle 6. A rotating mounting ring 30 is installed on the outer surface of the fixing ring 29. A shifting motor 31 is fixedly installed on the side surface of the mounting ring 30. A shifting gear 32 is fixedly disposed at one end of the rotating shaft of the shifting motor 31. A fitting pneumatic push rod 33 is fixedly installed on the side surface of the mounting ring 30. An electromagnet 35 is fixedly installed at the upper end of the fitting pneumatic push rod 33. A repair plate 34 is adsorbed on the side surface of the electromagnet 35. A toothed block is fixedly provided on the side surface of the fixed ring 29, and the shift gear 32 is connected to the fixed ring 29 by meshing through the toothed block on the side surface of the fixed ring 29; The repair plate 34 has an arc-shaped design, and the side of the repair plate 34 facing the electromagnet 35 is made of iron material. The side of the repair plate 34 facing the inner surface of the water pipe 4 is made of the same material as the water pipe 4, and the side of the repair plate 34 facing the inner surface of the water pipe 4 is coated with adhesive. After the inner wall of the leak point in the water pipe 4 is cleaned, the traveling vehicle 6 moves so that the repair plate 34 is directly facing the leak point. Then, the shifting motor 31 is started. The shifting motor 31 drives the shifting gear 32 to rotate. Through the meshing of the shifting gear 32 with the toothed blocks on the surface of the fixing ring 29, the mounting ring 30 rotates inside the fixing ring 29 until the mounting ring 30 drives the pneumatic push rod 33 to be directly facing the leak point. Then, the pneumatic push rod 33 is started to drive the repair plate 34, which is attracted above the electromagnet 35. The repair plate 34 is bonded to the inner wall of the leak point in the water pipe 4 by the adhesive coated on its surface. After a period of time, when the repair plate 34 is completely bonded to the inner wall of the water pipe 4, the electromagnet 35 is de-energized and releases the attraction on the iron side of the repair plate 34, completing the separation of the repair plate 34.
