Description

Technical Field

[0001] This utility model relates to the field of natural gas pipeline corrosion monitoring technology, specifically an intelligent natural gas pipeline corrosion monitoring device. Background Technology

[0002] Natural gas pipelines are pipelines that transport natural gas (including associated gas from oil fields) from extraction sites or processing plants to urban gas distribution centers or industrial users. They are also known as gas transmission pipelines. Using natural gas pipelines to transport natural gas is the main way to transport large quantities of natural gas on land. Natural gas pipelines account for about half of the world's total pipeline length. During long-term use, natural gas pipelines may leak due to corrosion of the inner wall. Therefore, it is necessary to monitor the corrosion of natural gas pipelines so that maintenance can be carried out in the first instance.

[0003] The published patent document CN217981330U discloses an online corrosion monitoring device for natural gas pipelines. This patent document describes a device using an electric motor. When the electric motor starts working, its output drives a series of interconnected structures. This causes a small gear to rotate, which in turn drives a large gear, displacing four arc-shaped plates and allowing the entire device to connect to different pipelines. However, the aforementioned patent document fixes the monitoring device inside the natural gas pipeline, requiring a gas shutdown operation, and it cannot monitor natural gas pipelines protected within a box culvert. Utility Model Content

[0004] The purpose of this invention is to provide an intelligent natural gas pipeline corrosion monitoring device, which solves the problems mentioned in the background art.

[0005] This application provides an intelligent natural gas pipeline corrosion monitoring device, comprising two semicircular components. Each semicircular component has two sets of walking components inside. Each set of walking components includes a long rod and an extension rod. The long rod is fixedly connected to the inner wall of the semicircular component, and a groove is formed on the side of the long rod away from the inner wall of the semicircular component. One end of the extension rod is located inside the groove and is fixedly connected to a spring, and the extension rod is slidably connected to the groove. A U-shaped component is fixedly installed at the end of the extension rod outside the groove. A roller is rotatably installed inside the U-shaped component, and a servo motor is fixedly installed on one side of one of the U-shaped components. The output end of the servo motor is fixedly installed to one of the rollers. An ultrasonic corrosion detector is fixedly installed on one side of one of the long rods.

[0006] Optionally, a cleaning assembly is provided on the lower part of one side of one of the extension rods. The cleaning assembly includes a support plate and two brushes. The support plate is fixedly installed on one side of the extension rod, and a mounting hole is opened in the middle of the support plate. An ultrasonic probe passes through the mounting hole. A threaded shaft is threaded through and threadedly connected to the support plate. A threaded hole is opened in the middle of the threaded shaft. A threaded shaft matching the threaded hole is fixedly installed on the top of the brush. The upper end of the threaded shaft is inside the threaded hole. The ultrasonic probe is located between the two brushes.

[0007] Optionally, the ultrasonic corrosion detector is electrically connected to the ultrasonic probe via a wire. A power supply box is fixedly installed on the inner wall of one of the semi-circular parts. A controller is provided on the front side of the power supply box, and a power storage device is provided inside the power supply box. The ultrasonic corrosion detector and the servo motor are electrically connected to the power storage device via the controller, and the controller is wirelessly connected to a mobile terminal.

[0008] Optionally, a bakelite screw is threaded through and connected to one side of the support plate, and a rubber pad is fixedly connected to one end of the bakelite screw, which contacts and abuts against the ultrasonic probe.

[0009] Optionally, four mounting bolts pass through between the two semicircular parts, and each mounting bolt is fitted with a matching nut.

[0010] Optionally, a handle may be fixedly mounted on the outer wall of one of the semicircular components.

[0011] Compared with the prior art, the beneficial effects of the technical solution of this application are as follows:

[0012] 1. The technical solution of this application uses a walking assembly consisting of a long rod, an extension rod, a slide, a spring, a U-shaped part, a roller, and a servo motor to drive the ultrasonic corrosion detector to move along the outside of the natural gas pipeline. It can be used for corrosion monitoring of natural gas pipelines protected by box culverts without stopping the gas supply. This makes the monitoring device suitable for natural gas pipelines of different diameters and can automatically move and adjust the various positions of the natural gas pipeline corrosion monitoring. It has a high degree of intelligence and can monitor the corrosion of natural gas pipelines protected by box culverts without stopping the gas supply.

[0013] 2. The technical solution of this application completes the installation of the cleaning component by attaching a brush to the outer wall of the natural gas pipeline and then rotating the threaded shaft one to allow the threaded shaft two to enter the interior of the threaded hole.

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0021] Please see Figure 1-2 This utility model provides an intelligent natural gas pipeline corrosion monitoring device, including two semi-circular parts 1. Each semi-circular part 1 has two sets of walking components 2 inside. Each set of walking components 2 includes a long rod 21 and an extension rod 22. The long rod 21 is fixedly connected to the inner wall of the semi-circular part 1, and a groove 23 is opened on the side of the long rod 21 away from the inner wall of the semi-circular part 1. One end of the extension rod 22 is inside the groove 23 and is fixedly connected to a spring 24. The extension rod 22 is slidably connected to the groove 23. A U-shaped part 25 is fixedly installed on the end of the extension rod 22 outside the groove 23. A roller 26 is rotatably installed inside the U-shaped part 25.

An ultrasonic corrosion detector 4 is fixedly installed on one side of one long rod 21. The ultrasonic corrosion detector 4 is model UM6800.

[0022] In this technical solution, by fitting two semi-circular parts 1 onto the natural gas pipeline protected by the box culvert, the elastic force of the spring 24 can drive the extension rod 22 to move towards the slide groove 23, so that the roller 26 is always attached to the outer wall of the natural gas pipeline. Then, by driving one of the rollers 26 to rotate through the servo motor 27, the ultrasonic corrosion detector 4 can move along the outside of the natural gas pipeline. It is suitable for natural gas pipelines of different diameters and can automatically move and adjust the various positions of the natural gas pipeline corrosion monitoring. It has a high degree of intelligence and can monitor the corrosion of natural gas pipelines protected by the box culvert without stopping the gas supply.

[0023] In some technical solutions, such as Figure 1 and Figure 3 As shown, a cleaning assembly 3 is provided on the lower part of one side of an extension rod 22. The cleaning assembly 3 includes a support plate 31 and two brushes 32. The support plate 31 is fixedly installed on one side of the extension rod 22, and a mounting hole 33 is opened in the middle of the support plate 31. An ultrasonic probe 10 passes through the inside of the mounting hole 33. A threaded shaft 34 is threaded through and threadedly connected to the support plate 31. A threaded hole 36 is opened in the middle of the threaded shaft 34. A threaded shaft 35 matching the threaded hole 36 is fixedly installed on the top of the brushes 32. The upper end of the threaded shaft 35 is inside the threaded hole 36. The ultrasonic probe 10 is located between the two brushes 32.

[0024] In use, the cleaning component is installed by attaching the brush 32 to the outer wall of the natural gas pipeline and then rotating the threaded shaft 34 to allow the threaded shaft 35 to enter the threaded hole 36. During the movement of the monitoring device, the brush 32 will clean the debris attached to the natural gas pipeline, thus not affecting the detection results of the ultrasonic probe 10.

[0025] In some technical solutions, such as Figure 1 and Figure 3 As shown, the ultrasonic corrosion detector 4 and the ultrasonic probe 10 are electrically connected by wires. A power supply box 5 is fixedly installed on the inner wall of a semi-circular part 1. A controller 6 is set on the front side of the power supply box 5, and a power storage power supply is set inside the power supply box 5. The ultrasonic corrosion detector 4 and the servo motor 27 are electrically connected to the power storage power supply through the controller 6, and the controller 6 is wirelessly connected to a mobile phone terminal.

[0026] In use, the ultrasonic corrosion detector 4 and servo motor 27 can be easily controlled remotely via the controller 6, which is wirelessly connected to a mobile terminal.

[0027] In some technical solutions, such as Figure 3-4As shown, a bakelite screw 37 is threaded through and connected to one side of the support plate 31. A rubber pad 38 is fixedly connected to one end of the bakelite screw 37, and the rubber pad 38 contacts and abuts against the ultrasonic probe 10.

[0028] In use, the ultrasonic probe 10 passing through the mounting hole 33 can be fixed by bakelite screw 37, and the friction on the ultrasonic probe 10 can be reduced by rubber pad 38.

[0029] In some technical solutions, such as Figure 1 As shown, four mounting bolts 7 pass through the two semicircular parts 1, and each mounting bolt 7 is fitted with a matching nut 8.

[0030] In use, the two semi-circular parts 1 can be easily installed and removed by using the mounting bolts 7 and nuts 8.

[0031] In some technical solutions, such as Figure 1 As shown, a handle 9 is fixedly installed on the outer wall of a semi-circular part 1.

[0032] When in use, the monitoring device is easy to carry using the handle 9.

[0033] Working principle: During use, two semi-circular parts 1 are fitted onto the natural gas pipeline protected by the box culvert. Due to the elasticity of the spring 24, the extension rod 22 can be moved towards the slide groove 23, so that the roller 26 is always attached to the outer wall of the natural gas pipeline. Then, the brush 32 is attached to the outer wall of the natural gas pipeline. Then, the threaded shaft 1 34 is rotated so that the threaded shaft 2 35 enters the inside of the threaded hole 36. The servo motor 27 drives one of the rollers 26 to rotate, so that the ultrasonic corrosion detector 4 can move along the outside of the natural gas pipeline. The brush 32 will clean the debris attached to the natural gas pipeline, so as not to affect the detection results of the ultrasonic probe 10.
