Description

Technical Field

[0001] This utility model relates to the field of natural gas pipeline technology, specifically a natural gas pipeline relocation and diversion device that does not interrupt transmission. Background Technology

[0002] Currently, during the maintenance, switching, or relocation of natural gas pipelines, most operations are conducted without interrupting gas supply to users. This typically involves installing a device with branch pipes and a perforation mechanism on the upstream pipeline via welding or bolting. After opening a hole using the perforation mechanism, natural gas is diverted to a temporary pipeline through the branch pipe, allowing for relocation of the downstream pipeline without affecting user gas usage. However, in practice, welding or bolting methods are generally inefficient, inconvenient, time-consuming, and labor-intensive. Furthermore, they hinder the rapid sealing of the downstream pipeline, making necessary operations difficult. Therefore, we propose a natural gas pipeline relocation and diversion device that allows for uninterrupted gas supply. Utility Model Content

[0003] The technical problem this invention aims to solve is to overcome existing defects and provide a natural gas pipeline relocation and diversion device that allows for uninterrupted transmission. The device uses a connecting assembly to lock the upper and lower clamping sleeves onto the upper and lower surfaces of the natural gas pipeline, respectively. A drive assembly then rotates a rotating shaft, which in turn rotates a drill bit. Simultaneously, a first electric push rod moves a sliding cover downwards, which in turn moves the rotating shaft and drill bit downwards. Under the combined action of the rotating shaft and the downward-moving drill bit, a hole is created in the natural gas pipeline. Simultaneously, the downward movement of the rotating shaft causes a collar, mounting bracket, and storage tank to pass through the first through hole. At this point, the storage tank is located inside the natural gas pipeline. The activation of the airbag assembly effectively seals the downstream section of the natural gas pipeline. This design not only allows for maintenance, replacement, or relocation of the downstream section of the natural gas pipeline without interrupting transmission, but also offers convenient operation and high maintenance efficiency, effectively solving the problems in the prior art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a natural gas pipeline relocation and diversion device that does not interrupt transmission, comprising an upper clamping sleeve, a lower clamping sleeve, a sliding cover, a rotating shaft, a connecting assembly, and a driving assembly;

[0005] The upper clamping sleeve and the lower clamping sleeve are connected by a connecting assembly. A flow divider box is installed on the upper surface of the upper clamping sleeve. A first through hole is opened in the middle of the upper clamping sleeve, and the upper clamping sleeve communicates with the flow divider box. A sealing groove is opened on the upper surface of the flow divider box. A sealing plate is installed on the lower end of each sliding cover. The sealing plate is slidably installed in the sealing groove. A branch pipe is installed on the upper surface of the flow divider box. A drive assembly is installed on the inner bottom surface of the sliding cover. A rotating shaft is installed at the output end of the drive assembly. A drill bit is installed at the lower end of the rotating shaft. The rotating shaft is located in the first through hole. A collar is rotatably mounted in the middle of the rotating shaft. A mounting bracket is mounted on one side of the collar. A storage box is mounted on the lower end of the mounting bracket. An airbag assembly is provided in the storage box. A sliding plate is mounted on the other side of the collar. A sliding groove is opened on the inner side of the diversion box. The sliding plate and the sliding groove are slidably connected. A fixed bracket is mounted on the outer side of the diversion box. A first electric push rod is mounted on the fixed bracket. A connecting bracket is mounted on the telescopic end of the first electric push rod. The outer end of the connecting bracket is connected to the sliding cover.

[0006] Furthermore, the connecting assembly includes bolts, nuts, and upper fixing plates installed on both sides of the upper clamping sleeve. Lower fixing plates are installed on both sides of the lower clamping sleeve. The upper and lower fixing plates have multiple corresponding second through holes evenly spaced. The bolts pass through the corresponding second through holes on the upper and lower fixing plates, and nuts are threaded onto the lower ends of the bolts. The upper and lower fixing plates are locked together by the bolts and nuts to clamp the natural gas pipeline.

[0007] Furthermore, the drive assembly includes a motor bracket mounted on the bottom surface inside the sliding cover, on which a motor is mounted. The output shaft of the motor is connected to the upper end of the rotating shaft via a coupling, and the input end of the motor is electrically connected to the output end of an external controller. The external controller controls the motor's operation, which in turn drives the rotating shaft to rotate, thus electrically completing the rotation of the rotating shaft.

[0008] Furthermore, the airbag assembly includes an airbag and a second electric push rod installed inside the storage tank. An mounting plate is installed at the end of the second electric push rod, and the airbag is fixedly connected to the mounting plate. A through groove is formed in the upper part of the storage tank, and an inflation pipe is installed on the upper surface of the airbag. The inflation pipe is located within the through groove, and its upper end passes through the top surface of a sliding cover. An inflation pump is installed on the sliding cover, and the inflation pipe is connected to the outlet of the inflation pump. An inflation valve is provided on the inflation pipe. When it is necessary to seal the downstream section of the natural gas pipeline, an external controller controls the inflation pump to operate. The inflation pump inflates the gas through the inflation pipe into the airbag, causing the airbag to expand and seal the downstream section of the natural gas pipeline.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: This natural gas pipeline relocation and diversion device, when in use, locks the upper and lower clamping sleeves onto the upper and lower surfaces of the natural gas pipeline respectively through the connecting assembly. Then, the drive assembly drives the rotating shaft to rotate, which in turn drives the drill bit to rotate. At the same time, the first electric push rod operates, causing the sliding cover to move downward. The downward movement of the sliding cover causes the rotating shaft and the drill bit to move downward. Under the action of the rotating and downward-moving drill bit, a hole is opened in the natural gas pipeline. Simultaneously, the downward movement of the rotating shaft causes the collar, mounting bracket, and storage tank to pass through the first through hole. At this time, the storage tank is located inside the natural gas pipeline. At the same time, the airbag assembly operates to effectively seal the downstream section of the natural gas pipeline. This setup not only allows for the inspection, replacement, or relocation of the downstream section of the natural gas pipeline without interrupting the supply, but also offers convenient operation and high maintenance efficiency.

[0016] The upper clamping sleeve 1 and the lower clamping sleeve 15 are connected by a connecting assembly. A flow divider box 8 is installed on the upper surface of the upper clamping sleeve 1. A first through hole 24 is opened in the middle of the upper clamping sleeve 1, and the upper clamping sleeve 1 and the flow divider box 8 are connected. A sealing groove 27 is opened on the upper surface of the flow divider box 8. A sealing plate 25 is installed on the lower end of the sliding cover 3. The sealing plate 25 is slidably installed in the sealing groove 27. A branch pipe 5 is installed on the upper surface of the flow divider box 8.

Inside the first through hole 24, a collar 26 is rotatably installed in the middle of the rotating shaft 9. A mounting bracket 10 is installed on one side of the collar 26. A storage box 11 is installed at the lower end of the mounting bracket 10. An airbag assembly is provided inside the storage box 11. A sliding plate 21 is installed on the other side of the collar 26. A sliding groove 20 is opened on the inner side of the diversion box 8. The sliding plate 21 and the sliding groove 20 are slidably connected. A fixed bracket 2 is installed on the outer side of the diversion box 8. A first electric push rod 7 is installed on the fixed bracket 2. A connecting bracket 6 is installed at the telescopic end of the first electric push rod 7. The outer end of the connecting bracket 6 is connected to the sliding cover 3.

[0017] In use, the upper clamping sleeve 1 and the lower clamping sleeve 15 are locked onto the upper and lower surfaces of the natural gas pipeline by the connecting assembly. Then, the drive assembly drives the rotating shaft 9 to rotate, which in turn drives the drill bit 17 to rotate. At the same time, the first electric push rod 7 drives the sliding cover 3 to move downward, which in turn drives the rotating shaft 9 and the drill bit 17 to move downward. Under the action of the rotating and downward moving drill bit 17, a hole is opened in the natural gas pipeline. At the same time, the downward movement of the rotating shaft 9 drives the collar 26, the mounting bracket 10, and the storage tank 11 to pass through the first through hole 24. At this time, the storage tank 11 is located inside the natural gas pipeline. At the same time, the gasbag assembly can effectively seal the downstream section of the natural gas pipeline. This setup not only allows for the inspection, replacement, or relocation of the downstream section of the natural gas pipeline without interrupting the supply, but also makes the operation convenient and the maintenance efficiency high.

[0018] The connecting assembly includes bolts 13, nuts 14, and upper fixing plates 12 installed on both sides of the upper clamping sleeve 1. Lower fixing plates 23 are installed on both sides of the lower clamping sleeve 15. Multiple corresponding second through holes are evenly distributed on the upper fixing plates 12 and 23. Bolts 13 pass through the corresponding second through holes on the upper and lower fixing plates 12 and 23, and nuts 14 are threaded onto the lower ends of the bolts 13. The upper fixing plates 12 and 23 are locked together by bolts 13 and nuts 14 to clamp the natural gas pipeline between the upper clamping sleeve 1 and the lower clamping sleeve 15.

[0019] The drive assembly includes a motor bracket 19 mounted on the bottom inner surface of the sliding cover 3. A motor 18 is mounted on the motor bracket 19. The output shaft of the motor 18 is connected to the upper end of the rotating shaft 9 via a coupling. The input end of the motor 18 is electrically connected to the output end of an external controller. The external controller controls the operation of the motor 18, which drives the rotating shaft 9 to rotate, thereby completing the rotation of the rotating shaft 9 electrically.

An mounting plate 28 is installed at the end of the second electric push rod 30, and the airbag 29 is fixedly connected to the mounting plate 28. A through groove is provided at the top of the storage tank 11. An inflation pipe 22 is installed on the upper surface of the airbag 29, and the inflation pipe 22 is located within the through groove. The upper end of the inflation pipe 22 passes through the top surface of the sliding cover 3. An inflation pump 4 is installed on the sliding cover 3, and the inflation pipe 22 is connected to the outlet of the inflation pump 4. An inflation valve is provided on the inflation pipe 22. When it is necessary to seal the downstream section of the natural gas pipeline, an external controller controls the inflation pump 4 to operate. The inflation pump 4 inflates the gas through the inflation pipe 22 into the airbag 29, causing the airbag 29 to expand and seal the downstream section of the natural gas pipeline.

[0021] The working principle of the natural gas pipeline relocation and diversion device provided by this utility model is as follows: In use, the upper clamping sleeve 1 and the lower clamping sleeve 15 are locked to the upper and lower surfaces of the natural gas pipeline respectively by the connecting assembly. Then, the drive assembly drives the rotating shaft 9 to rotate, which in turn drives the drill bit 17 to rotate. At the same time, the first electric push rod 7 drives the sliding cover 3 to move downward, which in turn drives the rotating shaft 9 and the drill bit 17 to move downward. Under the action of the rotating and downward moving drill bit 17, a hole is opened in the natural gas pipeline. At the same time, the downward movement of the rotating shaft 9 drives the collar 26, the mounting bracket 10 and the storage tank 11 to pass through the first through hole 24. At this time, the storage tank 11 is located inside the natural gas pipeline. At the same time, the airbag assembly can effectively seal the downstream section of the natural gas pipeline. This setup not only allows for the inspection, replacement or relocation of the downstream section of the natural gas pipeline without interrupting the supply, but also makes the operation convenient and the maintenance efficiency high. The upper fixing plate 12 and the lower fixing plate 23 are locked together by bolts 13 and nuts 14 to clamp the natural gas pipeline between the upper clamping sleeve 1 and the lower clamping sleeve 15. An external controller controls the motor 18, which drives the rotating shaft 9 to rotate, thus electrically completing the rotation of the shaft 9. When it is necessary to seal the downstream section of the natural gas pipeline, the external controller controls the inflation pump 4 to operate. The inflation pump 4 inflates the gas through the inflation pipe 22 into the gas bag 29, causing the gas bag 29 to expand and seal the downstream section of the natural gas pipeline.

[0022] It is worth noting that in this embodiment, the core chip of the external controller is an ATMIE microcontroller, specifically the AT89C51. The motor 18 and the air pump 4 can be freely configured according to the actual application scenario. The external controller controls the operation of the motor 18 and the air pump 4 using methods commonly used in the prior art, and the content not described in detail in this specification belongs to the prior art known to those skilled in the art.
