Description

Technical Field

[0001] The invention relates to the technical field of natural gas pipelines, and in particular discloses an unmanned monitoring device for safety risks in a natural gas operation area. Background Art

[0002] During the natural gas transportation process, with long-term use, the pipeline may become fragile or even rupture due to aging or erosion by external factors, which may lead to natural gas leakage. Therefore, in order to prevent this situation from causing greater harm, the natural gas center needs to arrange regular monitoring of the pipeline to detect and deal with leakage problems in time.

[0003] For safety, efficiency and other reasons, the most commonly used method is to use drones equipped with monitoring devices to inspect pipelines. However, this method has certain defects - the air flow fluctuations generated by drones during flight will accelerate the flow of gas, causing errors in the readings of the monitoring device, affecting the accuracy of the monitoring results and posing safety hazards; in addition, drones usually monitor from above the pipeline, which leads to a monitoring blind spot below the pipeline, that is, the monitoring cannot fully cover the pipeline. If the drone is designed to fly around the pipeline, although some blind spots can be made up, the flight distance of the drone will be greatly increased, affecting the monitoring efficiency. Summary of the invention

[0025] As Figure 1 , Figure 3 and Figure 4 shown in the figure, it further includes: an adjusting component arranged between the cross frame 14 and the rotating arm 15, and the adjusting component is used to adjust the surrounding range of the total frame, so that the monitoring device can be applicable to natural gas pipelines 01 of different sizes.

[0027] like Figure 1 , Figure 7 and Figure 8 As shown, it also includes: a marking component arranged on the mounting frame 11, the marking component is used to mark the leakage position on the pipeline 01, and a group of marking components are arranged on the upper and lower mounting frames 11, and the marking components include: the guide rail 41 fixedly installed on the mounting frame 11, and the guide rails 41 of the two groups of marking components are circled outside the pipeline 01 together; the moving block 42 slidably installed on the guide rail 41; the electric wheel 43 rotatably installed on the moving block 42, and the electric wheel 43 rolls in contact with the guide rail 41 to control the moving block 42 to move on the guide rail 41; the electric push rod 44 fixedly installed on the moving block 42 ; the motor C45 fixedly mounted on the telescopic end of the electric push rod 44; the cross bar 46 fixedly mounted on the output end of the motor C45; the marking pen 47 slidably mounted on the end of the cross bar 46; the elastic member 48 fixedly mounted between the marking pen 47 and the cross bar 46, the elastic member 48 is a compression spring; the fixing member B49 arranged on the cross bar 46, the cross bar 46 is divided into two, the fixing member B49 is a combination of a sleeve frame and an adjusting bolt, after changing the distance between the two parts of the cross bar 46, the sleeve frame and the cross bar 46 are compressed using the adjusting bolt, so that the cross bar 46 can be adjusted and fixed after adjustment.

[0028] like Figure 1 and Figure 7As shown, it further includes a blower 51 fixedly installed on the upper and lower layers of the mounting frame 11. The blower 51 is used to blow impurities on the pipeline 01, so that the marker pen 47 can mark smoothly, preventing impurities from affecting the marking effect.

[0029] Before using the monitoring device, adjust the distance between the two layers of the mounting frame 13 according to the size of the pipeline 01. Assume that the monitored pipeline 01 is a pipeline 01 of a larger size at this time. Control the motor A21 to control the upper rotating arm 15 to rotate upward and the lower rotating arm 15 to rotate downward, so as to control the two layers of the mounting frame 13 to separate from each other, achieving the purpose of expanding the range of the total frame, and untie the fixing member B49. Adjust the size of the marking range of the marker pen 47 by adjusting the length of the cross bar 46; after completion, remove the upper mounting frame 11 from the upper mounting frame 13, and untie the fixing member A16 to separate the upper mounting frame 13, disassemble the total frame from an annular shape into a linear shape. At this time, the monitoring device can be wound around the pipeline 01, and the magnetic wheel 33 is magnetically fixed outside the pipeline 01, so that the cross frame 14 and the rotating arm 15 slide relative to the mounting frame 13, that is, the monitoring device adapts to the size of the pipeline 01. Finally, use the fixing member A16 to fix the upper mounting frame 13 and install the upper mounting frame 11 back on the upper mounting frame 13, that is, complete the preparatory work before the monitoring device conducts monitoring.

[0030] After that, start the hub motor 32, and the monitoring device can be driven to move forward along the pipeline 01. Since the pipeline 01 is generally assembled using flanges, and the diameter of the flange is larger than that of the pipeline 01, the monitoring device automatically crosses obstacles by setting a traveling component. When moving to the flange, the motor B35 controls the mounting block 31 to retract towards the cross frame 14, so that the magnetic wheel 33 bypasses the flange. In particular, when each group of traveling components crosses obstacles in turn, among the three groups of traveling components on the same side, no matter which group crosses the obstacle, the other two groups remain connected to the pipeline 01, so as to ensure that the monitoring device can have stable support.

[0031] When the monitor 12 detects an increase in the local natural gas concentration in the pipeline 01, it can be determined that there is a natural gas leak in the pipeline 01. First, the blower 51 on the corresponding position side is started to blow impurities on the pipeline 01 within the blowing range. Subsequently, the marking component on the corresponding position side operates. The electric wheel 43 rotates to move the moving block 42 to the position of the natural gas leak. The electric push rod 44 extends to make the marking pen 47 abut against the pipeline 01, and the elastic member 48 is stretched. Then, the motor C45 operates to control the cross bar 46 to rotate one circle, so that the marking pen 47 draws a circle on the pipeline 01, so as to quickly find the leak position during subsequent maintenance. The elastic member 48 keeps the marking pen 47 in contact with the pipeline 01 all the time to ensure the marking effect.

[0032] After the monitoring operation is completed, remove the upper mounting bracket 11 and release the fixing member A16, and then the monitoring device can be removed from the pipeline 01.

[0033] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
