[0002] Natural gas pipelines are an important infrastructure for transporting natural gas. They are usually made of steel pipes because steel pipes have high strength, good sealing and aging resistance, and can withstand large pressure and temperature changes. During the transportation of natural gas, pipelines need to be monitored to prevent natural gas leaks.

[0003] Therefore, a long-distance pipeline leakage monitoring device, with the publication number CN216280701U, is first fixed by first connecting the upper connecting block and the lower connecting block through the outer rod thread, and then rotating the inner rod to drive the inner rod to move downward along the outer rod thread, thereby driving the support block to move downward from the center of the first support rod and the second support rod, so that the first support rod and the second support rod are supported to both sides, increasing the friction with the lower connecting block. An installation cavity is opened at the connection between the upper connecting block and the lower connecting block, and a monitoring body is installed in the installation cavity.

[0004] However, because the upper connecting block and the lower connecting block are fixed at specific positions on the surface of the pipeline, in actual use, the monitoring body set in the installation cavity only detects a certain point of the pipeline, and cannot achieve the detection effect of the entire area, and cannot accurately detect leaks in open positions.

[0021] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] like Figure 1-4 As shown, a long-distance pipeline leakage monitoring device includes an ultrasonic detector 12 and a track 1 set along the direction of the long-distance pipeline. The ultrasonic detector 12 can be FlexSonic TMThe acoustic wave detector is designed to identify the unique ultrasonic frequency components of events such as gas leaks. If a pressurized gas leak occurs, the frequency components of the sound generated exceed the audible part of the spectrum and extend into the ultrasonic region (above 20kHz). The surface of the track 1 is slidably connected to a slide 7, and the ultrasonic detector 12 is mounted on the surface of the slide 7. The surface of the slide 7 is fixedly connected to a connecting seat 10. The side of the connecting seat 10 is fixedly connected to a number of plug-in plates 14 distributed in a linear array and passing through the mounting holes of the ultrasonic detector 12. By moving the slide 7 along the surface of the track 1, the ultrasonic detector 12 can be moved to any area of ​​the long-distance pipeline. The top edge of the side of the connecting seat 10 is plugged with a plug strip. 16. There are two rotating handles 13 symmetrically arranged about the inserting strip 16 for rotation connection near the top edge. Several inserting plates 14 are divided into two rows according to their positions, and one swinging edge of the two rotating handles 13 is respectively engaged with the side edges of the inserting plates 14 at the two rows. The two sides of the bottom surface of the inserting strip 16 are respectively rotatably connected to the other swinging edge ends of the two rotating handles 13, and the top edge of the inserting strip 16 is fixedly connected to the elastic rope 5 connected to the top edge of the connecting seat 10. In actual use, the elastic rope 5 ensures that the position of the inserting strip 16 is stable, and the rotation connection between the inserting strip 16 and the rotating handle 13 is utilized to keep the two rotating handles 13 as shown in FIG. Figure 2 In the state shown, the two rotating handles 13 are used to clamp the two rows of plug plates 14 to prevent the ultrasonic detector 12 from falling from the plug plates 14. By pressing down the plug strips 16 to elastically stretch the elastic rope 5, the plug strips 16 are lowered to rotate the rotating handles 13 to disengage from the plug plates 14, so that the ultrasonic detector 12 can be directly removed from the plug plates 14.

[0024] In addition: several pairs of clamps 3 are embedded in the surface of the track 1, and the outer sides of each pair of clamps 3 are flush with the surface of the track 1 and are fixed by embedded bolts. The outer wall of one of the clamps 3 in each pair of clamps 3 is fixedly connected to a connecting rod 4 for connecting to the surface of the long-distance pipeline. The connection between the connecting rod 4 and the clamp 3 is utilized to achieve that the track 1 is fixed at the same distance from the surface of the long-distance pipeline. A slot 2 spanning several clamps 3 is provided on the surface of the track 1 along the center line direction. An electric roller 8 is embedded and rotatably connected to the inner wall of the slot 2 on the slide 7. The electric roller 8 is driven to rotate by installing a motor on the slide 7, and the electric roller 8 is driven to roll in the slot 2 to drive the slide 7 to move on the surface of the track 1.

[0025] In addition: the top edge of the connecting seat 10 is also fixedly connected to a connecting frame 17, the top of the connecting frame 17 is rotatably connected to a solar panel 6, and the bottom edge of the side of the connecting seat 10 is provided with a battery 11 electrically connected to the solar panel 6, the ultrasonic detector 12 and the electric roller 8. According to common sense, equipment that matches the solar panel 6 is selected and installed on the side of the connecting seat 10 to realize the transmission of electricity generated by the solar panel 6 to the battery 11 for storage.

[0026] In addition: the bottom position of the connecting frame 17 is rotatably connected to two winding wheels 18, two traction ropes 9 are wound around the two winding wheels 18, and the traction ropes 9 on the two winding wheels 18 are respectively connected to the two sides of the solar panel 6 relative to the connecting frame 17. The end faces of the two winding wheels 18 on the same side extend outward through the connecting frame 17 and are fixedly connected with a gear 19. The two gears 19 are meshed and connected, and one of the gears 19 is driven by a motor. The surface of the connecting frame 17 is also provided with two pulleys 15 driven by a belt strip, one of which is fixed on the end face of the rotation point of the solar panel 6, and the other pulley is fixed on the end face of the rotation point of the solar panel 6. 15 is fixed on the end face of one of the gears 19. In actual use, the motor is used to drive the corresponding gear 19 to rotate, and then the other meshing gear 19 is reversed, so that the two winding wheels 18 can rotate in opposite directions. The two additional pulleys 15 ensure that the solar panel 6 rotates synchronously. Therefore, the angle is adjusted by rotating the solar panel 6, and the two winding wheels 18 rotate in opposite directions to release or reel in the tilt of the solar panel 6. That is, the traction rope 9 is used to pull the side of the solar panel 6 obliquely to prevent the solar panel 6 from tilting or turning over due to wind.

[0027] Working principle: When in use, the track 1 is fixed to the surface of the long-distance pipeline using the connecting rod 4 and the clamp 3, and the battery 11 is used to drive the electric roller 8 to rotate, so that the slide 7 moves along the surface of the track 1, and then the connecting seat 10 moves. The movement of the connecting seat 10 drives the ultrasonic detector 12 installed on its surface to move, thereby realizing detection of different areas on the surface of the long-distance pipeline.

[0028] The wiring diagram of the motor, solar panel 6, battery 11 and ultrasonic detector 12 in the present invention is common knowledge in the field, and its working principle is a well-known technology. The model is selected according to the actual use. Therefore, the control method and wiring arrangement of the motor, solar panel 6, battery 11 and ultrasonic detector 12 are not explained in detail.
