Description

Technical Field

[0001] The utility model relates to the technical field of oil and gas pipeline monitoring, in particular to an oil and gas pipeline monitoring device. Background Art

[0002] During the process of transporting media, oil and gas pipelines are extremely vulnerable to the impact and corrosion of the media. Therefore, the technology for real-time detecting the pipeline wall has emerged as the times require. Ultrasonic thickness measurement probes are generally installed at the pipeline elbows where the repeated impact and corrosion are the greatest to detect the thickness change at the pipeline elbows. Since the pipeline diameters are inconsistent and the outer walls of the pipeline elbows are mostly arc-shaped, and the ultrasonic thickness measurement probes need to be in close contact with the outer wall of the pipeline, the existing technology uses a magnetic attraction method to improve the installation speed of the monitoring probes. However, in the application of existing oil and gas pipelines, there is a phenomenon that the outer wall of the elbow is uneven, resulting in some deviation when simply using the magnetic attraction method for positioning. Content of the Utility Model

[0003] In order to overcome at least one of the above-mentioned defects of the existing technology, the utility model provides an oil and gas pipeline monitoring device, which can solve the problem that the monitoring probe positioned by the magnetic attraction method cannot accurately monitor the old pipelines.

[0004] The technical solution adopted by the utility model to solve its problem is as follows:

[0005] An oil and gas pipeline monitoring device includes:

[0006] A plurality of monitoring probes, each monitoring probe includes a housing, a magnet and a thickness measurement sensor. The magnet is annular and assembled on one end face of the housing. The housing is provided with a through hole, and the thickness measurement sensor is arranged in the through hole. The through hole and the annular magnet are coaxially arranged. Adjusting screws are provided at the four corner points of the housing;

[0007] A connecting plate for connecting adjacent monitoring probes;

[0008] Wherein, a plurality of the monitoring probes are evenly distributed along the circumferential direction of the pipeline to be monitored.

[0009] By adopting the above scheme, the design of the annular magnet enables the monitoring probe to be quickly positioned on the pipeline, thereby improving the installation efficiency. The annular magnet is closely attached to the pipeline surface, ensuring that the monitoring probe is firmly adsorbed and maintaining good stability even in a vibrating environment. In addition, the adjusting screws provided at the four corner points of the housing allow users to finely adjust the position of the monitoring probe according to the actual situation. It is applicable to those old pipelines with uneven surfaces. Through the adjusting screws, the monitoring probe can adapt to different pipeline curvatures and surface conditions, ensuring that the thickness measurement sensor is in close contact with the outer wall of the pipeline, and thus improving the accuracy of the monitoring data.

[0010] In addition, multiple monitoring probes are evenly distributed along the circumferential direction of the pipeline, enabling all-round monitoring, avoiding monitoring blind spots caused by a single monitoring point, and improving the reliability and integrity of the overall monitoring.

[0011] Furthermore, it further includes a communication module, the communication module is communicatively connected to all the thickness measurement sensors, there are three monitoring probes, the communication module and the three monitoring probes are arranged at equal intervals in sequence along the circumferential direction of the pipeline to be monitored, and both sides of the communication module are respectively connected to the shells of the adjacent monitoring probes through the connecting plates.

[0012] By adopting the above scheme, the monitoring of the elbow of the oil and gas pipeline transportation pipeline mainly focuses on the outer wall of the elbow, followed by the pipe walls on both sides of the elbow. The wear of the inner wall of the elbow due to the impact of the transmission medium is the smallest. Therefore, this part of the elbow is not monitored, but a communication module is set. The communication module is communicatively connected to all thickness measurement sensors, can collect data from each monitoring probe in real time, and synchronously transmit these data to a remote terminal, providing a basis for remote monitoring and facilitating the timely discovery and handling of potential problems.

[0013] Furthermore, the shell includes a base, an assembly cylinder and a cover plate. One end of the assembly cylinder is connected to the base, and the other end is connected to the cover plate. The thickness measurement sensor is arranged in the assembly cylinder.

[0014] By adopting the above scheme, the shell is divided into three parts: the base, the assembly cylinder and the cover plate, making the monitoring probe easy to assemble and disassemble, facilitating maintenance and component replacement. The modular design also helps with standardized production and reduces manufacturing costs. And the thickness measurement sensor is installed in the assembly cylinder, making the installation of the sensor simpler and facilitating the alignment and debugging work between the sensor and the pipeline.

[0015] Furthermore, the base is provided with an assembly groove for installing the connecting plate, and the depth of the assembly groove is the same as the thickness of the connecting plate.

[0016] By adopting the above scheme, the matching design of the assembly groove and the connecting plate enables the connecting plate to be easily inserted into the assembly groove of the base, simplifies the installation steps, improves the installation efficiency, and the depth of the assembly groove matches the thickness of the connecting plate, ensuring that the connecting plate will not shake or loosen during installation, thereby enhancing the connection stability between the monitoring probes.

[0017] Furthermore, it further includes a storage module, and the storage module is communicatively connected to the communication module.

[0018] By adopting the above solution, since most of the oil and gas pipelines are laid in remote areas or environments with poor signals, correspondingly, the monitoring devices are also located in remote areas or environments with poor signals. The storage module can ensure the integrity and accuracy of the monitoring data, continuously collect data even without instant communication, and then the storage module can transmit the stored information to the satellite within a time period measured in days. In this way, it can be ensured that even without communication for a long time, the monitoring data can be regularly transmitted, ensuring the timely collection of data. And the urgency of monitoring the wall thickness of the pipeline is not so strong. This setting method reduces the dependence on real-time communication, and even without the ability of instant communication, the monitoring system can continue to operate and record data.

[0019] Furthermore, the storage module is arranged inside the housing of the communication module, and the storage module is electrically connected to the communication module.

[0020] By adopting the above solution, integrating the storage module inside the housing of the communication module makes the entire monitoring device more compact, reduces additional hardware requirements, and facilitates installation and maintenance.

[0021] In summary, the oil and gas pipeline monitoring device provided by the present utility model has the following technical effects:

[0022] 1. The design of the annular magnet enables the monitoring probe to be quickly positioned on the pipeline, improving the installation efficiency;

[0023] 2. The annular magnet is closely attached to the surface of the pipeline, ensuring that the monitoring probe can maintain good stability even in a vibrating environment.

[0024] 3. The adjusting screws provided at the four corner points of the housing allow users to finely adjust the position of the monitoring probe according to the actual situation, which is applicable to old pipelines with uneven surfaces.

[0025] 4. Through the adjusting screws, the monitoring probe can adapt to different pipeline curvatures and surface conditions, ensuring that the thickness measurement sensor is in close contact with the outer wall of the pipeline, improving the accuracy of the monitoring data.

Obviously, what is described here is only a part of the examples of the present invention, not all of the examples.

[0030] For the convenience of understanding the embodiments of the present invention, the following will take specific embodiments as examples and make further explanatory descriptions in conjunction with the drawings, and each embodiment does not constitute a limitation to the embodiments of the present invention.

[0031] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present invention belongs. The terms used in the description of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0033] Refer to Figure 1 - Figure 2 , the present invention discloses an oil and gas pipeline monitoring device, including a plurality of monitoring probes 1 and a connecting plate 2. The monitoring probe 1 includes a housing 11, a magnet 12 and a thickness measurement sensor 13. The magnet 12 is annular and is assembled on one end face of the housing 11. The housing 11 is provided with a through hole, and the thickness measurement sensor 13 is arranged in the through hole. The through hole and the annular magnet 12 are coaxially arranged. Adjusting screws 14 are provided at the four corner points of the housing 11. The connecting plate 2 is used to connect adjacent monitoring probes 1. Among them, a plurality of monitoring probes 1 are circumferentially and evenly arranged along the monitored pipeline 4.

[0034] The working principle of the above structure is that the magnet 12 is directly adsorbed on the pipeline 4 to be monitored. When a number of monitoring probes 1 are evenly distributed and adsorbed in the above manner, and then a number of monitoring probes 1 are connected end to end through the connecting plate 2, a wall thickness monitoring device evenly distributed along the circumference of the pipeline 4 to be monitored is formed. If the monitoring probe 1 is not aligned with the pipeline 4 to be monitored, the height of the adjusting screws 14 provided at the four corner points of the housing 11 can be adjusted to make the thickness measuring sensor 13 perpendicular to the pipe wall of the pipeline 4 to be monitored. Thus, on those old pipelines with uneven surfaces, through the adjusting screws 14, the monitoring probe 1 can adapt to different pipeline curvatures and surface conditions, ensuring that the thickness measuring sensor 13 is in close contact with the outer wall of the pipeline, thereby improving the accuracy of the monitoring data.

[0035] In this embodiment, since the monitoring of the elbows of the oil and gas pipeline conveying pipeline mainly focuses on the pipe wall on the outer side of the elbow, followed by the pipe walls on both sides of the elbow, and the wear of the pipe wall on the inner side of the elbow due to the impact of the transmission medium is the smallest, so the monitoring is not carried out for this part of the elbow, but a communication module 3 is set up.

[0036] Specifically, the monitoring device further includes a communication module 3. The communication module 3 is communicatively connected to all the thickness measuring sensors 13. There are three monitoring probes 1. The communication module 3 and the three monitoring probes 1 are arranged at equal intervals in sequence along the circumference of the pipeline 4 to be monitored. Both sides of the communication module 3 are respectively connected to the housing 11 of the adjacent monitoring probe 1 through the connecting plate 2. The above communication module 3 is communicatively connected to all the thickness measuring sensors 13, which can collect the data from each monitoring probe 1 in real time and synchronously transmit these data to a remote terminal, providing a basis for remote monitoring and facilitating the timely discovery and handling of potential problems.

[0037] In some embodiments, for the convenience of assembling the monitoring probe 1, the housing 11 includes a base 111, an assembly cylinder 112 and a cover plate 113. One end of the assembly cylinder 112 is connected to the base 111, and the other end is connected to the cover plate 113. The thickness measuring sensor 13 is arranged inside the assembly cylinder 112.

[0038] Specifically: The housing 11 is divided into three parts: the base 111, the assembly cylinder 112 and the cover plate 113, making the monitoring probe 1 easy to assemble and disassemble, facilitating maintenance and replacement of components. The modular design also helps with standardized production and reduces manufacturing costs. And the thickness measuring sensor 13 is installed inside the assembly cylinder 112, making the installation of the sensor simpler and also facilitating the alignment and debugging work between the sensor and the pipeline.

[0039] In some embodiments, in order to improve the connection stability between several monitoring probes 1, the base 111 is provided with an assembly groove for installing the connecting plate 2, and the depth of the assembly groove is the same as the thickness of the connecting plate 2. Specifically, the matching design of the assembly groove and the connecting plate 2 enables the connecting plate 2 to be easily inserted into the assembly groove of the base 111, simplifies the installation steps, and improves the installation efficiency. The depth of the assembly groove matches the thickness of the connecting plate 2, ensuring that the connecting plate 2 will not shake or loosen during installation, thereby enhancing the connection stability between the monitoring probes 1.

[0040] In some embodiments, since most of the oil and gas pipelines are laid in remote areas or environments with poor signals, correspondingly, the monitoring device is also located in remote areas or environments with poor signals. Considering that the data on pipeline wall thickness monitoring will not be damaged due to overly thin pipe walls in a very short time, therefore, the monitoring device provided by the present utility model further includes a storage module, and the storage module is communicatively connected to the communication module 3.

[0041] Specifically, the storage module can ensure the integrity and accuracy of the monitoring data, continuously collect data even in the absence of instant communication, and then the storage module can transmit the stored information to the satellite in a time cycle based on days. In this way, it can be ensured that even in the case of no communication for a long time, the monitoring data can be regularly sent out to ensure the timely collection of data. And the urgency of monitoring the pipeline wall thickness is not that strong. This setting method reduces the dependence on real-time communication, and even in the absence of instant communication capabilities, the monitoring system can continue to operate and record data.

[0042] Furthermore, to facilitate the assembly of the storage module and the communication module 3, the storage module is arranged inside the housing of the communication module 3, and the storage module is electrically connected to the communication module 3. Integrating the storage module inside the housing of the communication module 3 makes the entire monitoring device more compact, reduces additional hardware requirements, and facilitates installation and maintenance.

[0043] The technical means disclosed in the solution of the present utility model are not limited to the technical means disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements are also regarded as the protection scope of the present utility model.
