Description

[0002] Natural gas is a gaseous fossil fuel composed primarily of methane. It is primarily found in oil and gas fields, with a small amount also found in coal seams. Like crude oil, natural gas is buried in closed underground geological structures. Some are stored in the same layers as crude oil, while some exist separately. With the development of city gas, gas facilities have become popular in all major, medium and small cities.

[0027] See also Figure 1 - Figure 5 As shown, this embodiment provides a city gas pipeline leakage detection and positioning device, including a pipeline body 1, and also includes:

[0028] The upper clamps 2 are symmetrically arranged on the outside of the pipe body 1, and one side of each of the two upper clamps 2 is hinged with a lower clamp 3;

[0029] The plugboard 14 is fixedly connected to the bottom of the two upper clamps 2, and the bottom of the two lower clamps 3 is fixedly connected to the mounting frame 12. The interior of the two mounting frames 12 is provided with a guide groove for the movement of the plugboard 14.

[0033] The angle adjustment component is arranged above the pipe body 1 and is used to adjust the angle of the detection and positioning component, thereby facilitating the disassembly and assembly between the entire device and the pipe body 1 by the staff.

[0034] The above working principle: when it is necessary to inspect and process the pipe body 1, it is only necessary to first fix the upper clamp 2 and the lower clamp 3 through the fixing component. At this time, the entire device can be fixedly installed on the outside of the pipe body 1. When the entire device is fixed and installed, the detection and positioning component starts to operate. At this time, the detection and positioning component can effectively perform leakage detection on the pipe body 1. When the detection and positioning component detects the leakage location, it will transmit the signal to the staff's mobile phone or other devices, so that the staff can view it. During the operation of the detection and positioning component, the horizontal adjustment component also starts to operate synchronously. At this time, the horizontal adjustment component can drive the detection and positioning component to move synchronously, so that the detection and positioning component can move horizontally on the outside of the pipe body 1, thereby effectively improving the detection efficiency of the detection and positioning component and the accuracy of the results. At the same time, it can facilitate the detection and positioning component to locate the leaking part of the pipe body 1.

At this time, the entire device can be fixedly installed on the outside of the pipe body 1.

[0036] Taking into account that when gas leakage occurs in the pipeline body 1, the pipeline body 1 needs to be inspected, so the detection and positioning component includes an arc plate 7 symmetrically arranged on the outside of the pipeline body 1, and laser detectors 8 are fixedly installed on the opposite sides of the two arc plates 7. The outsides of the two arc plates 7 are fixedly connected to displays 9. The two laser detectors 8 and the displays 9 are electrically connected through wires. The outsides of the two displays 9 are provided with alarm lights 10. When gas detection processing is required for the pipeline body 1, the laser detector 8 starts to run. At this time, the pipeline body 1 can be effectively detected and processed by the laser detector 8. When the laser detector 8 detects the location of the gas leakage, it will transmit the data to the display 9. At this time, it is convenient for the staff to view the data and it is convenient for the staff to locate the leakage location of the pipeline body 1.

When the laser detector 8 detects the leakage part of the pipeline body 1, it will transmit a signal to the controller, and the controller will control the drive motor 5 to stop running. At this time, it is convenient for the staff to locate the leakage position of the pipeline body 1, which effectively improves the positioning efficiency and accuracy of the pipeline body 1.

The insides of multiple turntables 27 are evenly spaced with guide grooves for the movement of the insertion rods 26. When the inclination angle of the laser detector 8 needs to be adjusted or the entire device needs to be disassembled, it is only necessary to pull the outer plate 24 first. At this time, the outer plate 24 will drive the side plate 23 to move synchronously, and the side plate 23 will then drive the contact plate 21 to move synchronously on the outside of the slide bar 20. During the movement of the resistance plate 21, the resistance spring 22 is squeezed, the outer plate 24 also drives the connecting block 25 to move synchronously, and the connecting block 25 drives the insertion rod 26 to move synchronously. When the insertion rod 26 is out of the guide groove inside the turntable 27, the arc plate 7 is dialed. At this time, the arc plate 7 drives the L-shaped plate 11 to move synchronously, and the L-shaped plate 11 drives the rotating rod 18 to rotate synchronously, and the rotating rod 18 drives the turntable 27 to rotate synchronously. When the inclination angle adjustment of the laser detector 8 is completed or the angle of the arc plate 7 is sufficient for the staff to adjust the device When the entire assembly is disassembled, the outer plate 24 is loosened, and the resistance spring 22 is reset, driving the resistance plate 21 to move synchronously, and the resistance plate 21 then drives the outer plate 24 to move synchronously, and the outer plate 24 then drives the connecting block 25 and the insertion rod 26 to move synchronously.
