Description

Technical Field

[0001] This utility model relates to an installation structure and monitoring device for monitoring leaks in oil and gas well pipelines. Background Technology

[0002] Oil and gas well pipelines face a significant risk of leakage during long-term use. Leaks can cause substantial losses of oil and gas resources, severely impact the surrounding environment, and even trigger safety accidents. Therefore, real-time and reliable leak monitoring of oil and gas well pipelines is crucial.

[0003] Currently, existing leak monitoring installation structures for oil and gas well pipelines require specific installation configurations for different wells and pipelines. These structures have poor adaptability and lack flexibility, often making it difficult to effectively adjust the preload between the monitoring device and the pipeline after installation. This can lead to swaying between the device and the pipeline, affecting the reliability of monitoring. Therefore, this paper proposes a new leak monitoring installation structure and monitoring device for oil and gas well pipelines. Utility Model Content

[0004] The purpose of this utility model is to provide an installation structure and monitoring device for monitoring leaks in oil and gas well pipelines, so as to solve the problem mentioned in the background art that the existing installation structures for monitoring leaks in oil and gas well pipelines have poor adaptability and cannot be flexibly adjusted.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an installation structure for monitoring leaks in oil and gas well pipelines, including an upper sleeve and a lower sleeve disposed on the outer periphery of the oil and gas well pipeline. Both the upper and lower sleeves are semi-circular in shape, allowing them to fit snugly around the outer periphery of the oil and gas well pipeline. A pre-tightening force fine-tuning component is disposed in the middle of the lower sleeve, and an inner lining top plate is disposed above the pre-tightening force fine-tuning component, with the inner sidewall of the inner lining top plate engaging with the inner sidewall of the lower sleeve. A connecting seat plate for connecting an oil and gas well pipeline leak monitoring device is disposed above the upper sleeve.

[0006] The lower sleeve is adjusted by the pre-tightening force fine-tuning component to raise the inner liner top plate and adjust the pre-tightening force between the upper sleeve, the lower sleeve and the oil and gas well pipeline.

[0007] The lower part of the lower sleeve is provided with a limiting plate, and the limiting plate is stepped in shape.

[0008] Preferably, the preload fine-tuning component includes an internal groove formed on the inner wall side of the limiting plate, an adjusting cylinder is provided inside the internal groove, and the tail end of the adjusting cylinder is connected to the inner lining top plate.

[0009] Preferably, the adjusting cylinder is provided with an adjusting screw inside, and an adjusting bolt is provided at the tail end of the adjusting screw, and the adjusting bolt extends outside the limiting plate so that an external hex wrench can rotate the adjusting screw through the adjusting bolt.

[0010] Preferably, the inner wall of the adjusting cylinder is provided with an internal thread, and the internal thread cooperates with the adjusting screw.

[0011] Preferably, guide wings are provided on both sides of the adjusting cylinder, and the guide wings are rectangular in shape;

[0012] The built-in groove has limiting grooves on both sides that cooperate with the guide wing.

[0013] Preferably, both sides of the upper and lower sleeves are provided with connecting holes, and the connecting holes are provided with fixing bolts, the lower part of which is fixed by a nut.

[0014] Preferably, the upper sleeve, the lower sleeve, and the inner wall of the inner lining top plate are all provided with rubber pads.

[0015] Preferably, an oil and gas well pipeline leakage monitoring device includes an oil and gas well pipeline leakage monitoring installation structure.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] This invention, through the pre-tightening force fine-tuning component, can flexibly adjust the pre-tightening force between the upper and lower sleeves and the oil and gas well pipeline, preventing loosening of the connection between the monitoring device and the pipeline, and improving the stability and reliability of monitoring.

[0018] It can be adapted to different specifications of oil and gas well pipelines, solving the problem of poor compatibility of existing installation structures and improving the ability to adapt to different pipeline conditions.

[0019] The fit between the inner lining top plate and the inner wall of the lower sleeve ensures a stable connection between the monitoring device and the pipeline, reducing errors caused by loosening or instability, thereby improving monitoring stability.

[0020] The design of the adjusting screw and adjusting bolt allows for easy external adjustment using tools (such as an Allen wrench), facilitating the optimization and adjustment of the preload. This prevents shaking between the monitoring device and the pipeline due to improper preload, improving the reliability of monitoring and overcoming the shortcomings of existing structures in effectively adjusting the preload. It also facilitates maintenance and repair.

[0021] Thanks to the stability of the installation structure and the preload adjustment function, the device will not experience monitoring errors caused by shaking or loosening during long-term use, thereby reducing the impact of external interference on the monitoring results.

Detailed Implementation

[0031] To address the problem of poor adaptability and inflexible adjustment of existing oil and gas well pipeline leakage monitoring installation structures, this utility model provides an oil and gas well pipeline leakage monitoring installation structure and its monitoring device. The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0032] Please see Figure 1-8This utility model provides an installation structure for monitoring leaks in oil and gas well pipelines, including an upper sleeve 1 and a lower sleeve 2 disposed on the outer periphery of the oil and gas well pipeline. The upper sleeve 1 and the lower sleeve 2 are both semi-circular arc-shaped so that they fit on the outer periphery of the oil and gas well pipeline. A pre-tightening force fine-tuning component 3 is disposed in the middle of the lower sleeve 2. An inner lining top plate 4 is disposed above the pre-tightening force fine-tuning component 3, and the inner sidewall of the inner lining top plate 4 mates with the inner sidewall of the lower sleeve 2. A connecting seat plate 9 for connecting an oil and gas well pipeline leak monitoring device is disposed above the upper sleeve 1. The pre-tightening force fine-tuning component 3 includes an internal groove 31 opened on the inner wall of a limiting plate 21. An adjusting cylinder 32 is disposed inside the internal groove 31, and the tail end of the adjusting cylinder 32 is connected to the inner lining top plate 4. An adjusting screw 33 is provided inside the adjusting cylinder 32, and an adjusting rod 34 is provided at the tail end of the adjusting screw 33. The adjusting rod 34 extends to the outside of the limiting plate 21, so that an external hex wrench can rotate the adjusting screw 33 through the adjusting rod 34. An internal thread 321 is provided on the inner wall of the adjusting cylinder 32, and the internal thread 321 cooperates with the adjusting screw 33. Guide wings 35 are provided on both sides of the adjusting cylinder 32, and the guide wings 35 are rectangular in shape; limiting grooves 311 that cooperate with the guide wings 35 are provided on both sides of the built-in groove 31.

[0033] Both sides of the upper sleeve 1 and the lower sleeve 2 are provided with connecting holes 5, and the connecting holes 5 are provided with fixing bolts 6. The lower part of the fixing bolts 6 is connected and fixed by nuts 7. The upper sleeve 1, the lower sleeve 2 and the inner wall of the inner lining top plate 4 are all provided with rubber pads 8.

[0034] The lower sleeve 2 adjusts the lifting of the inner lining top plate 4 through the pre-tightening force fine-tuning component 3, thereby adjusting the pre-tightening force between the upper sleeve 1, the lower sleeve 2 and the oil and gas well pipeline.

[0035] The lower part of the lower sleeve 2 is provided with a limiting plate 21, and the limiting plate 21 is stepped in shape.

[0036] An oil and gas well pipeline leakage monitoring device includes an oil and gas well pipeline leakage monitoring installation structure.

[0037] The working principle of the oil and gas well pipeline leakage monitoring installation structure and its monitoring device provided by this utility model is as follows:

[0038] Place the lower sleeve 2 at the bottom of the oil and gas well pipeline, and then connect the upper sleeve 1 to the lower sleeve 2 with the fixing bolt 6;

[0039] When it is necessary to adjust the preload between the upper sleeve 1 and the lower sleeve 2 and the pipe, an Allen wrench can be used. By turning the adjusting rod 34 with the Allen wrench, the adjusting screw 33 will be rotated. Since the inner wall of the adjusting cylinder 32 has an internal thread 321 that matches the adjusting screw 33, the rotation of the adjusting screw 33 will cause the adjusting cylinder 32 to move axially.

[0040] The axial movement of the regulating cylinder 32 causes the inner liner top plate 4 to move upward or downward. When the inner liner top plate 4 moves upward, it abuts against the side of the oil and gas well pipeline, thereby increasing the pre-tightening force of the upper sleeve 1 and lower sleeve 2 on the oil and gas well pipeline; conversely, when the inner liner top plate 4 moves downward, the pre-tightening force decreases. The cooperation of the guide wings 35 and the limiting grooves 311 on both sides ensures the smoothness and accuracy of the movement of the regulating cylinder 32, avoids the regulating cylinder 32 from deflecting during the movement, and ensures the uniformity of the pre-tightening force adjustment.

[0041] Then, the monitoring device is installed onto the upper sleeve 1 via the connecting base plate 9, thus completing the installation and fixing of the monitoring device.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
