Description

Technical Field

[0001] This invention relates to the field of pipeline shaping and repair technology, and in particular to an integrated device for pipeline deformation detection and shaping. Background Technology

[0002] Pipeline transportation is the mainstay of oil and gas transportation in my country. By the end of 2019, the total length of long-distance oil and gas pipelines in my country had reached 139,000 kilometers, of which buried pipelines accounted for a large proportion. Due to earthquakes, ground movement, crustal changes, heat transport deformation, construction damage, and other reasons, buried pipelines often experience varying degrees of deformation or even rupture, resulting in a decrease in oil and gas transmission rates or even production stoppages. This poses a crisis to the safe operation of pipelines, and if not dealt with in a timely manner, it often leads to catastrophic consequences. To ensure the safe operation of pipelines, deformation and pressure testing should be conducted before commissioning and after geological disasters. However, accurately locating the deformation of buried pipelines remains a significant challenge. While existing diameter detectors can detect pipeline deformation, they rely on odometer wheels to locate the deformation. The calculation of the deformation location is based on the number of wheel rotations. However, the odometer wheel may slip rapidly during its movement, leading to an underestimation of the calculated distance, or rotate along a non-linear trajectory along the pipeline wall, resulting in an overestimation. This leads to a large cumulative error. Although various algorithms exist to correct and compensate for the odometer wheel-based positioning method, for long-distance buried pipelines, the distance between the located deformation location and the actual deformation location still exists, significantly complicating subsequent reshaping construction and increasing costs. Currently, pipeline deformation detection and pipeline reshaping are two separate construction stages. Deformation detection must be performed first, followed by pipeline excavation and reshaping. This results in a long overall construction period and low efficiency. Furthermore, pipeline excavation is costly, especially since some pipelines cross ponds, rivers, and highways, and backfilling is required after excavation and reshaping, further increasing construction costs. Summary of the Invention

[0003] The purpose of this invention is to provide an integrated device for pipeline deformation detection and shaping, so as to solve the problem that pipeline deformation detection and pipeline shaping are two separate construction steps in the prior art, resulting in a long overall construction cycle and high construction cost.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: An integrated device for detecting and shaping pipeline deformation includes a cylindrical body sealed at both ends. The cylindrical body is provided with a flexible support component and a flexible drive component for interference fit with the inner wall of the pipeline. A flexible shaping cylinder is sealed on the outside of the cylindrical body, forming a shaping and pressurizing cavity between the two. The cylindrical body or the shaping cylinder is provided with a pressurizing channel communicating with the shaping and pressurizing cavity. The outer diameter of the shaping cylinder is greater than or equal to the inner diameter of the pipeline before deformation. The cylindrical body is provided with a front stop structure and a rear stop structure for blocking the shaping cylinder from the front and rear ends, respectively. The outer diameter of the front stop structure is smaller than the inner diameter of the pipeline that can be deformed, and the outer diameter of the rear stop structure is smaller than the outer diameter of the shaping cylinder that is opened and equal to the inner diameter of the pipeline that can be deformed.

[0005] Furthermore, the shaping cylinder includes a large-diameter section and front and rear small-diameter sections connected to both ends of the large-diameter section. The front and rear small-diameter sections are sealed and fitted outside the cylinder body so that the large-diameter section and the cylinder body form the shaping and pressurizing cavity. The front baffle structure and the rear baffle structure are respectively fitted on the front and rear small-diameter sections and respectively form stops with the front and rear ends of the large-diameter section.

[0006] Furthermore, front and rear small diameter sections are respectively fitted with front and rear sealing sleeves, which are fixed relative to the cylinder body to seal and press the front and rear small diameter sections onto the cylinder body.

[0007] Furthermore, the front sealing sleeve has a first outward flange at its rear end, which forms a stop with the front end of the large diameter section. The first outward flange constitutes the front stop structure. The rear sealing sleeve has a second outward flange at its front end, which forms a stop with the rear end of the large diameter section. The second outward flange constitutes the rear stop structure.

[0008] Furthermore, a first sealing sleeve is provided between the front small diameter section and the cylinder to achieve a sealed fit between the front small diameter section and the cylinder, and a second sealing sleeve is provided between the rear small diameter section and the cylinder to achieve a sealed fit between the rear small diameter section and the cylinder. Both the first and second sealing sleeves are fixed on the cylinder.

[0009] Furthermore, both the first and second sealing sleeves are threaded onto the cylinder.

[0010] Furthermore, the flexible support component includes a first support cup and a second support cup, which are respectively disposed at the front and rear ends of the cylinder to support the cylinder.

[0011] Furthermore, the cylinder is equipped with an oil storage chamber, which is connected to the pressurization channel via an oil pipeline. An oil pump is connected to the oil pipeline, and the cylinder is also equipped with a controller. The controller is electrically connected to the oil pump to control the operation of the oil pump to achieve oil delivery or return.

[0012] Furthermore, the cylinder is also equipped with power supply components for supplying power to the controller and the oil pump.

[0013] Furthermore, a pressure sensor is provided at the rear end of the cylinder for detecting the pressure inside the pipe on the rear side of the cylinder, and the pressure sensor is electrically connected to the controller.

[0014] Beneficial Effects: This invention is a pioneering creation. The cylinder is sealed at both ends and equipped with a flexible support component and a flexible drive component. After the device is placed inside the pipe, the flexible support component is interference-fitted with the inner wall of the pipe, providing support for the device. The flexible drive component is also interference-fitted with the inner wall of the pipe, allowing the pumped liquid pressure to act on the flexible drive component, pushing it and thus propelling the entire device forward. During the forward movement of the device, the shaping cylinder remains in an unopened state. Because the outer diameter of the front baffle structure is smaller than the pipe's allowable deformation inner diameter, and the outer diameter of the rear baffle structure is smaller than the opening outer diameter of the shaping cylinder but equal to the pipe's allowable deformation inner diameter, the device can be used within the allowable deformation range of the pipe section. When encountering a pipe section with significant deformation (i.e., the inner diameter of the deformed pipe is smaller than the allowable deformation inner diameter), the front baffle can pass through the deformed section, while the rear baffle is blocked and cannot pass, preventing the device from proceeding. In this case, hydraulic oil or gas can be injected into the shaping and pressurizing chamber via an oil or gas source, causing the shaping cylinder to expand. The shaping cylinder then compresses the deformed section of the pipe, performing the shaping operation. Once the shaping is complete, the hydraulic oil or gas in the shaping and pressurizing chamber is returned to the oil or gas source, allowing the expanded shaping cylinder to return to its original shape. The rear baffle can then pass smoothly through the deformed section, completing the pipe deformation detection and shaping for that location. This invention's integrated pipe deformation detection and shaping device can detect and shape all pipe deformations in a single operation, breaking the previous limitations of separate buried pipe detection and shaping operations. This significantly shortens the construction cycle, greatly improves work efficiency, and eliminates the need for pipe excavation, significantly reducing construction costs.

[0016] When buried pipelines deform, the deformed area cannot be directly observed. Therefore, devices such as diameter detectors are typically used to detect the deformation and then reshape it. If the pipeline deformation is minor and within the allowable deformation range (i.e., the deformed inner diameter is between the original inner diameter and the allowable deformation inner diameter), reshaping is not necessary. However, if the deformation exceeds the allowable range (i.e., the deformed inner diameter is smaller than the allowable deformation inner diameter), reshaping is required. The allowable deformation inner diameter refers to the minimum inner diameter within the allowable deformation range. Currently, pipeline deformation detection and reshaping are two separate processes, which are not only time-consuming and inefficient but also costly.

[0017] To overcome the shortcomings of existing technologies, this invention proposes an integrated device for pipeline deformation detection and reshaping. The basic concept of this invention is to combine a pipeline deformation detection structure and a pipeline reshaping structure into a single device and insert it into the pipeline. After detecting pipeline deformation, the deformed part is directly reshaped by the pipeline reshaping structure. All pipeline deformations can be detected and reshaped in one operation without the need to excavate the pipeline, thereby shortening the construction cycle and reducing construction costs.

[0018] Based on the above inventive concept, the embodiments of the present invention will be described in detail below.

[0019] like Figure 1As shown, the integrated pipe deformation detection and shaping device of the present invention includes a cylindrical body 8, which is a through-type structure. A front end cap 1 is threadedly connected to the front opening of the cylindrical body 8, and a first sealing ring 18 is provided between the front end cap 1 and the front end cap 18 to seal the front end of the cylindrical body 8. Similarly, a rear end cap 17 is threadedly connected to the rear end opening of the cylindrical body 8, and a second sealing ring 29 is provided between the rear end cap 17 and the rear end cap 17 to seal the rear end of the cylindrical body 8. A mileage wheel 31 is provided at the right end of the rear end cap 17, and the mileage wheel 31 is fixedly connected to the rear end cap 17 by bolts. A shaping cylinder 7 is fitted externally to the cylindrical body 8. The shaping cylinder 7 is made of flexible material and includes a large-diameter section and two small-diameter sections connected at the front and rear ends of the large-diameter section. The large-diameter section is used for expanding and shaping the pipe, and the two small-diameter sections are fitted externally to the cylindrical body 8, forming a shaping and pressurizing cavity between the large-diameter section and the cylindrical body 8. This structural design of the shaping cylinder 7 provides a larger sealing contact area with the cylindrical body 8, resulting in a better sealing effect. A front sealing sleeve 2 is fitted externally to the front small-diameter section. The left end of the front sealing sleeve 2 is fixedly connected to the front end cover 1 by bolts. The front sealing sleeve 2 seals and presses the front small-diameter section tightly onto the cylinder 8. A first sealing sleeve 19 is provided between the front small-diameter section and the cylinder 8 to achieve a sealing fit. A rear sealing sleeve 12 is fitted externally to the rear small-diameter section. The right end of the rear sealing sleeve 12 is threaded onto the cylinder 8. The rear sealing sleeve 12 seals and presses the rear small-diameter section tightly onto the cylinder 8. A second sealing sleeve 23 is provided between the rear small-diameter section and the cylinder 8 to achieve a sealing fit. The compression method presses the front and rear ends of the shaping cylinder 7 onto the cylinder 8 to achieve a seal. The compression is reliable and can ensure that the ends of the shaping cylinder 7 will not separate from the cylinder 8 or move relative to it when the pressure inside the shaping cylinder 7 is high, making the seal at both ends of the shaping cylinder 7 more reliable. The first sealing sleeve 19 and the second sealing sleeve 23 are both fixedly connected to the cylinder 8 by threads, making assembly convenient.

[0020] The front sealing sleeve 2 has a first outward flange at its rear end. This first outward flange fits tightly against the front end of the large-diameter section of the shaping cylinder 7 to form a stop. The first outward flange constitutes a front stop structure for stopping the shaping cylinder 7 from the front end. The rear sealing sleeve 12 has a second outward flange at its front end. This second outward flange fits tightly against the rear end of the large-diameter section to form a stop. The second outward flange constitutes a rear stop structure for stopping the shaping cylinder 7 from the rear end. By setting the front and rear stop structures, the expansion of the shaping cylinder 7 in the front-rear direction is restricted, constraining the shaping cylinder 7 to expand only in the radial direction, thereby ensuring the shaping effect. Setting the first outward flange at the rear end of the front sealing sleeve 2 to form the front stop structure and setting the second outward flange at the front end of the rear sealing sleeve 12 to form the rear stop structure helps to reduce the number of parts in the device, making assembly convenient and ensuring reliable stopping.

[0021] The outer diameter of the first outward flange is smaller than the maximum outer diameter of the shaping cylinder 7 (i.e., the expanded outer diameter of the shaping cylinder 7), and smaller than the allowable deformation inner diameter of the pipe, so that the shaping cylinder 7 can enter the deformed position of the pipe for shaping operations. The outer diameter of the second outward flange is slightly smaller than the expanded outer diameter of the shaping cylinder 7 and equal to the allowable deformation inner diameter of the pipe. The second outward flange can only pass through when the deformed inner diameter of the pipe is larger than the outer diameter of the second outward flange; otherwise, it will be blocked here and shaping operations will be required.

[0022] The front sealing sleeve 2 is fitted with, from left to right, a first support cup 3, a first spacer ring 4, a first drive cup 5, and a first adjusting spacer ring 6. The left end of the first support cup 3 is tightly fitted with the front end cover 1, and the right end of the first adjusting spacer ring 6 is tightly fitted with the first outward flange at the rear end of the front sealing sleeve 2. The inner diameter of the left end of the front sealing sleeve 2 is small and is in close contact with the outer circumference of the cylinder 8.

[0023] The outer side of the cylinder 8 is fitted with a second adjusting spacer 14, a second driving cup 15, a second spacer 27, and a second supporting cup 16 in sequence between the rear sealing sleeve 12 and the rear end cover 17. The left end of the second adjusting spacer 14 is tightly fitted with the rear sealing sleeve 12, and the right end of the second supporting cup 16 is fitted with the rear end cover 17.

[0024] The first adjusting spacer ring 6 and the second adjusting spacer ring 14 are used to adjust the tightness between the components to ensure reliable installation and operation. The first support cup 3 and the second support cup 16 are respectively located at the front and rear ends of the cylinder 8, and together they form a flexible support component that can provide more stable support for the device. In addition, by setting spacer rings, which work in conjunction with the cups, the support strength of the cylinder 8 can be enhanced, making the support more reliable.

[0025] The cylinder 8 contains, from left to right, an oil storage chamber 9, an oil pump 21, a fixed base 22, a drive motor 13, a controller 25, and a power supply component 26. The oil storage chamber 9 stores hydraulic oil. The cylinder 8 has a pressurization channel 11 connecting to the shaping and pressurizing chamber. The oil storage chamber 9 and the pressurization channel 11 are connected via an oil pipeline 20. The oil pump 21 is connected to the oil pipeline 20, which also has a flow meter and pressure gauge assembly 10 connected to it. The drive motor 13 is fixedly mounted on the right end of the fixed base 22. The fixed base 22 has a through hole in its center. The motor shaft passes through the through hole and is connected to the drive shaft of the oil pump 21 via a coupling, enabling the oil pump 21 to rotate in both directions to achieve oil delivery or return. The oil pump 21 is specifically a gear pump, a current product. The power supply component 26 is specifically a battery, used to power the controller 25, drive motor 13, and other components. The drive motor 13, flow meter and pressure gauge assembly 10, and odometer wheel 31 are all electrically connected to the controller 25 via wires 24, and the controller 25 performs data analysis and control. A pressure sensor 30 is located at the rear end of the cylinder 8, on the right side of the rear end cover 17. The pressure sensor 30 is used to detect the pressure inside the pipeline at the rear of the cylinder 8. The pressure sensor 30 is electrically connected to the controller 25, and the controller 25 can analyze the data transmitted from the pressure sensor 30 to determine whether there is a malfunction in the pipeline pumping.

[0026] Inside the cylinder 8, at the right end of the battery, there is also a signal transmitting coil 28. The signal transmitting coil 28 is electrically connected to the controller 25 and can transmit electromagnetic pulse signals to penetrate the signal shield of the pipeline. When the device malfunctions and cannot pass through the deformed position of the pipeline after the reshaping operation, the controller 25 will control the signal transmitting coil 28 to transmit electromagnetic pulse signals to inform the operators of its position. The operators will then calculate the cumulative discharge by pumping, and use the signal receiver to locate the device by excavation.

[0027] Before operation, a portion of hydraulic oil is pumped into the shaping and pressurizing chamber through the oil pump 21. Then, 60%-80% of the space in the oil storage chamber 9 is filled with hydraulic oil. After that, the device is placed in the launching tube of the pipeline and the device is pushed forward by pumping. The first support cup 3 and the second support cup 16 can play a good supporting role and support the entire device. The first drive cup 5 and the second drive cup 15 drive the entire device forward under the push of the pumped fluid. When encountering pipe deformation, the outer diameter of the first outer flange of the front sealing sleeve 2 is small, allowing it to pass through the deformed part of the pipe. However, the outer diameter of the second outer flange of the rear sealing sleeve 12 is larger and will be blocked by the deformed part, preventing the device from moving forward. At this time, the controller 25 can know that the device has stopped operating through the data transmitted by the odometer wheel 31. Then, it retrieves the data transmitted by the pressure sensor 30 for analysis to determine whether the inability to move forward is due to pipe deformation, a pumping malfunction, or a work stoppage. The basic judgment principle is as follows: When the odometer wheel 31 transmits information that the device cannot move forward, if the pressure sensor 30 at the rear end shows that the pressure is continuously increasing, it indicates that the inability to move forward is due to pipe deformation, and a reshaping operation is required; if the pressure sensor 30 at the rear end shows that the pressure remains unchanged or continuously decreases, it indicates that the inability to move forward is due to a pumping malfunction or a work stoppage, and a reshaping operation is not required.

[0028] Shaping Operation: Once it is determined that the device cannot move forward due to pipeline deformation, the controller 25 starts to control the drive motor 13 to drive the oil pump 21 to rotate in the forward direction. At this time, the flow direction of hydraulic oil is: oil reservoir 9 → oil pump 21 → shaping cylinder 7. The hydraulic oil in the oil reservoir 9 is pumped into the shaping and pressurizing chamber for shaping operation. The flow meter and pressure gauge assembly 10 records data in real time. The pumping operation at the pipeline launching end continues to maintain the pushing pressure in the pipeline. When the data recorded by the flow meter and pressure gauge assembly 10 reaches the pre-set shaping limit of the shaping cylinder 7, it indicates that the pipeline shaping has met the requirements and can be maintained for a period of time. Then, the controller 25 controls the drive motor 13 to drive the oil pump 21 to rotate in the reverse direction. At this time, the flow direction of hydraulic oil is: shaping cylinder 7 → oil pump 21 → oil reservoir 9, realizing oil return and restoring the expanded shaping cylinder 7 to its original shape. The second outer flange of the rear sealing sleeve 12 passes through the pipeline deformation part, and the mileage wheel 31 resumes operation. The pipeline deformation detection and shaping at this point are completed.

[0029] The integrated pipeline deformation detection and reshaping device of this invention has the advantage of being able to detect and reshape all pipeline deformations in a single operation. The device is reliable and breaks through the limitations of separate detection and reshaping operations for buried pipelines, shortening the construction cycle, significantly improving work efficiency, and is simple in principle and easy to operate, eliminating the need for pipeline excavation and greatly reducing construction costs. This device can operate independently or in conjunction with a pipeline pig, a diameter gauge, and a magnetic flux leakage detector. Furthermore, it facilitates easy location and positioning for operators in extremely complex operating conditions, making it widely applicable and with a promising market prospect.

[0030] Of course, the present invention is not limited to the embodiments described above.

[0031] For example, in another embodiment, a shaping cylinder with a different structure is provided. The shaping cylinder does not have a large-diameter section and a small-diameter section. The radial dimensions of each part are the same and larger than the outer diameter of the cylinder. The two ends of the shaping cylinder are directly vulcanized and fixed to the cylinder body. The front baffle structure and the rear baffle structure are directly fitted onto the outer circumferential surface of the cylinder body and respectively fit with the front and rear ends of the shaping cylinder to form a stop. The front baffle structure and the rear baffle structure can be the front sealing sleeve and the rear sealing sleeve in the above embodiment, or they can be ordinary retaining rings.

[0032] For example, in another embodiment, a different fixing method for the shaping cylinder is provided, in which the small diameter sections at both ends of the shaping cylinder are directly vulcanized and fixed to the cylinder body.

[0033] For example, in another embodiment, different front and rear stop structures are provided. The rear end of the front sealing sleeve and the front end of the rear sealing sleeve are not provided with outward flanges. Instead, a front stop ring and a rear stop ring are provided as the front and rear stop structures, respectively. The front and rear stop rings are respectively fitted onto the front and rear small diameter sections of the shaping cylinder. The front stop ring is pressed against the front end of the large diameter section of the shaping cylinder by the front sealing sleeve, and the rear stop ring is pressed against the rear end of the large diameter section of the shaping cylinder by the rear sealing sleeve, thereby forming a stop for the shaping cylinder from both the front and rear ends.

[0034] For example, in another embodiment, both the first and second sealing sleeves are fitted onto the cylinder body with an interference fit, thereby fixing the two sealing sleeves onto the cylinder body. Other fixing methods can also be used for the first and second sealing sleeves, which will not be listed here.

[0035] For example, in another embodiment, both the first and second sealing sleeves are made of rubber and are fixed to the cylinder by a vulcanization process.

[0036] For example, in another embodiment, instead of setting the first and second sealing sleeves, the front and rear small diameter sections of the shaping cylinder are directly sealed and pressed against the outer circumferential surface of the cylinder.

[0037] For example, in another embodiment, a support cup is provided only at the left end of the cylinder, and a drive cup may not be provided at the left end. A drive cup is provided only at the right end of the cylinder, and a support cup may not be provided at the right end. The support cup at the left end and the drive cup at the right end together support the device. Of course, more support cups can be provided; or the drive cup at the left end of the cylinder can be omitted, and only the drive cup at the right end of the cylinder can be retained.

[0038] For example, in another embodiment, instead of setting up an oil tank inside the cylinder, a continuous oil pipe is connected to the rear end of the device. The continuous oil pipe is connected to a pressurization channel, and the shaping cylinder is pressurized through the continuous oil pipe to expand and shape the cylinder.

[0039] For example, in another embodiment, the entire device is powered by a cable, in which case a battery may or may not be installed inside the cylinder.

The scope of patent protection of the present invention shall be determined by the claims. Similarly, any equivalent structural changes made based on the description and drawings of the present invention shall also be included within the scope of protection of the present invention.
