Description

Technical Field

[0001] This utility model relates to a pipeline detection and positioning device, specifically a carbon rod drag-type pipeline detection and positioning device, belonging to the field of gas pipeline detection technology. Background Technology

[0002] In recent years, urban development has entered a period of rapid growth, with infrastructure construction continuously upgrading. Road reconstruction projects focus on optimizing the traffic network, widening main roads, and adding overpasses; urban beautification projects reshape the city's appearance by creating scenic belts and increasing green coverage; and stormwater and sewage improvement projects aim to improve drainage systems and enhance the city's flood control and drainage capabilities. The intensive implementation of these projects has made the utilization of underground space increasingly complex, posing unprecedented challenges to the precise management and efficient maintenance of underground gas pipeline networks. During construction, gas pipelines frequently intersect and overlap with other pipelines. Improper construction can easily lead to safety accidents such as gas leaks. Therefore, how to safely and efficiently conduct gas pipeline inspections has become a key issue in urban construction.

[0003] Traditional gas pipeline detection methods are increasingly revealing their limitations in today's complex construction environments. For long-distance pipelines, traditional methods require multiple positioning and repeated measurements, resulting in extremely low efficiency. When encountering complex pipeline routes such as tees, bends, and diameter changes, the positioning accuracy drops significantly, making it difficult to accurately determine the actual pipeline path. Furthermore, traditional detection relies on frequent excavation of pits, which not only damages urban roads, green belts, and other public facilities, incurring high repair costs, but also may damage other underground pipelines, threatening the safety of the gas pipeline network. Therefore, a carbon rod drag-type pipeline detection and positioning device is proposed. Utility Model Content

[0004] In view of this, the present invention provides a carbon rod drag-type pipeline detection and positioning device to solve or alleviate the technical problems existing in the prior art, and at least provides a beneficial option.

[0005] The technical solution of this utility model embodiment is implemented as follows: a carbon rod drag-type pipeline detection and positioning device includes a gas pipeline, and a detection and positioning component is provided inside the gas pipeline. The detection and positioning component includes two support frames, a drag plate, a limiting plate, a contact wheel, a limiting ring, four support sleeves, a sliding rod, a support spring, and a connecting rod.

[0006] The two support frames are fixedly connected by a connecting rod. The drag plate is fixedly connected to one side of one support frame, the limiting plate is fixedly connected to one side of the other support frame, the four support sleeves are symmetrically fixedly connected inside the support frame, the sliding rod is slidably connected to the inner side wall of the support sleeve, the limiting ring is fixedly connected to the outer side wall of the sliding rod, the support spring is sleeved on the outer side wall of the sliding rod, and the contact wheel is installed at one end of the sliding rod.

[0007] More preferably, one end of the support spring abuts against the limiting ring, and the other end of the support spring abuts against the support sleeve.

[0008] More preferably, the limiting plate has a through hole inside, and a carbon rod is slidably connected inside the through hole.

[0009] More preferably, a positioning sleeve is fixedly connected to one side of the drag plate, and the end of the carbon rod away from the limiting plate is inserted into the interior of the positioning sleeve.

[0010] More preferably, four threaded pressure plates are symmetrically fixedly connected to one side of the limiting plate, and the outer side wall of the carbon rod is attached to the inner side wall of the four threaded pressure plates.

[0011] More preferably, all four threaded pressure plates are arc-shaped and coaxially arranged, and the outer walls of the four threaded pressure plates are threadedly connected to a threaded locking disc.

[0012] More preferably, a towing hook is fixedly connected to the side of the towing plate away from the support frame.

[0013] More preferably, the support frame is located inside the gas pipeline, and the outer wall of the contact wheel is attached to the inner wall of the gas pipeline.

[0014] The present invention has the following advantages due to the adoption of the above technical solution:

[0015] This invention uses a traction rope to pull a tow plate, allowing the support frame to move inside the gas pipeline. Simultaneously, a carbon rod moves within the gas pipeline. While the carbon rod moves, workers use an electromagnetic sensor outside the gas pipeline to capture real-time changes in the electromagnetic field. If the gas pipeline has defects such as deformation, blockage, or corrosion, abnormal changes in the electromagnetic field will occur, allowing for the identification of a problem at the corresponding location, thus achieving the purpose of detection and location. Compared to existing technologies, this invention uses a detection and location component to move the carbon rod within the gas pipeline, thereby achieving precise location of the fault point. This eliminates the need for excavating an operating pit, reducing detection costs and improving detection efficiency. Furthermore, during the detection process, the cooperation of support springs, sliding rods, and other structures increases the passability of the detection and location component.

In addition to the illustrative aspects, embodiments, and features described above, further aspects, embodiments, and features of the present invention will become readily apparent from the accompanying drawings and the following detailed description.

Detailed Implementation

[0024] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0025] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0026] like Figures 1-5As shown, this utility model embodiment provides a carbon rod drag-type pipeline detection and positioning device, including a gas pipeline 31. The gas pipeline 31 is provided with a detection and positioning component 101. The detection and positioning component 101 includes two support frames 11, a drag plate 12, a limiting plate 15, a contact wheel 20, a limiting ring 21, four support sleeves 22, a sliding rod 23, a support spring 24, and a connecting rod 25.

[0027] Two support frames 11 are fixedly connected by a connecting rod 25. A drag plate 12 is fixedly connected to one side of a support frame 11. A drag hook 13 is fixedly connected to the side of the drag plate 12 away from the support frame 11. Through the cooperation of the drag hook 13 and the drag plate 12, the detection and positioning component 101 can be dragged. During the dragging process, the gas pipeline 31 can be detected.

[0028] The support frame 11 is located inside the gas pipeline 31, and the outer side wall of the contact wheel 20 is attached to the inner side wall of the gas pipeline 31;

[0029] When the detection and positioning component 101 detects the gas pipeline 31, it drives the carbon rod 16 to move inside the gas pipeline 31. When the carbon rod 16 moves inside the gas pipeline 31, it changes the distribution of the surrounding electromagnetic field. Then, the staff uses an electromagnetic sensor on the outside of the gas pipeline 31 to capture these electromagnetic field change signals in real time. If the gas pipeline 31 has defects such as deformation, blockage, or corrosion, it will cause abnormal changes in the electromagnetic field, which can then determine that there is a problem in the gas pipeline 31 at the corresponding location, thus achieving the purpose of detection and positioning.

[0030] In this utility model, the carbon rod 16 and the electromagnetic sensor are both existing technologies, so their working principle, internal structure and usage will not be described in detail.

[0031] The limiting plate 15 is fixedly connected to one side of another support frame 11. Four support sleeves 22 are symmetrically fixedly connected to the inside of the support frame 11. The sliding rod 23 is slidably connected to the inner side wall of the support sleeve 22. The contact wheel 20 is installed at one end of the sliding rod 23. When the detection and positioning component 101 is dragged, the support frame 11 moves in the gas pipeline 31 through the four contact wheels 20. The contact wheels 20 can reduce the friction during movement.

[0032] In one embodiment, the limiting ring 21 is fixedly connected to the outer wall of the sliding rod 23, and the support spring 24 is sleeved on the outer wall of the sliding rod 23. One end of the support spring 24 abuts against the limiting ring 21, and the other end of the support spring 24 abuts against the support sleeve 22. The limiting ring 21 is pushed by the support spring 24, and the limiting ring 21 drives the sliding rod 23. The sliding rod 23 moves away from the support frame 11 inside the support sleeve 22, so that the contact wheel 20 can keep in contact with the inner wall of the gas pipeline 31. Under the combined action of the four contact wheels 20, the support frame 11 can be kept in the middle position of the gas pipeline 31, which enhances the stability during travel.

[0033] In one embodiment, a through hole 19 is provided inside the limiting plate 15, and a carbon rod 16 is slidably connected inside the through hole 19. A positioning sleeve 14 is fixedly connected to one side of the drag plate 12. The end of the carbon rod 16 away from the limiting plate 15 is inserted into the inside of the positioning sleeve 14. Through the cooperation of the through hole 19 and the positioning sleeve 14, the position of the carbon rod 16 can be limited, thereby enhancing the stability of the carbon rod 16.

[0034] In one embodiment, four threaded pressure plates 18 are symmetrically fixedly connected to one side of the limiting plate 15. The outer side wall of the carbon rod 16 is attached to the inner side wall of the four threaded pressure plates 18. The four threaded pressure plates 18 are all arc-shaped and coaxially arranged. The outer side walls of the four threaded pressure plates 18 are threadedly connected to a threaded locking disc 17. The threaded pressure plates 18 are made of plastic. The wall thickness of the threaded pressure plates 18 gradually increases on the side away from the limiting plate 15. Therefore, when the threaded locking disc 17 is rotated clockwise, the threaded locking disc 17 moves along the threaded pressure plates 18 and gradually moves away from the limiting plate 15. The threaded pressure plates 18 can gradually lock the carbon rod 16, thereby ensuring the stability of the carbon rod 16. During the movement, the carbon rod 16 will not fall off.

[0035] In operation, the present invention involves: installing and fixing the carbon rod 16 by inserting it sequentially into the through hole 19 and the positioning sleeve 14; then rotating the threaded locking disc 17 clockwise, causing it to move along the threaded pressure plate 18 and gradually move away from the limiting plate 15; the threaded pressure plate 18 gradually locks the carbon rod 16, thus ensuring its stability; passing a traction rope through the gas pipeline 31 and connecting it to the tow hook 13; then placing the detection and positioning component 101 inside the gas pipeline 31; and having the support frame 11 connected to the gas pipeline through four contact wheels 20. When the pipe 31 comes into contact, the support spring 24 is compressed and pulled by the traction rope to drag the towing plate 12. The support frame 11 moves inside the gas pipe 31. At the same time, the carbon rod 16 moves inside the gas pipe 31. When the carbon rod 16 moves inside the gas pipe 31, the staff uses an electromagnetic sensor on the outside of the gas pipe 31 to capture the electromagnetic field change signal in real time. If the gas pipe 31 has defects such as deformation, blockage, or corrosion, it will cause abnormal changes in the electromagnetic field. In this way, it can be determined that there is a problem in the gas pipe 31 at the corresponding location, thus achieving the purpose of detection and positioning.

[0036] Compared with the prior art, this utility model uses the detection and positioning component 101 to drive the carbon rod 16 to move inside the gas pipeline 31, thereby achieving accurate positioning of the fault point of the gas pipeline 31, eliminating the step of digging an operation pit, reducing detection costs, and improving detection efficiency. Moreover, during the detection process, the passability of the detection and positioning component 101 is increased by the cooperation of the support spring 24, sliding rod 23 and other structures.

[0037] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
