Description

Technical Field

[0001] The utility model relates to the field of natural gas transportation. More specifically, the utility model relates to a leakage detection device for natural gas pipeline transportation. Background Art

[0002] Natural gas pipelines are mainly used for the long-distance transportation of natural gas, and they are mainly buried underground, with some above the ground. Due to the particularity of the medium transported by natural gas pipelines, if leakage occurs, it will bring huge potential safety hazards. Therefore, during the use of natural gas pipelines, it is necessary to detect the leakage of natural gas pipelines. For the part of the natural gas pipeline above the ground, traditionally, workers hold detectors to conduct inspections. However, since the pipeline is relatively long, manual inspection is inefficient and slow, and it is very difficult to detect leaks in a timely manner when they occur. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a leakage detection device for natural gas pipeline transportation, which can detect the leakage of natural gas pipelines to ensure that leaks can be detected in a timely manner when they occur in natural gas pipelines.

[0004] The technical solution for the utility model to solve the above technical problems is as follows: A leakage detection device for natural gas pipeline transportation includes:

[0005] Two positioning plates, which are sleeved on the natural gas pipeline at intervals;

[0006] A driving mechanism, which is arranged on the two positioning plates;

[0007] A moving ring, which is sleeved between the two positioning plates and connected to the driving mechanism, and the driving mechanism drives the moving ring to move between the two positioning plates;

[0008] Multiple detection probes, which are evenly distributed on the inner side of the moving ring;

[0009] A controller, which is electrically connected to all the detection probes.

[0010] Furthermore, in the leakage detection device for natural gas pipeline transportation, the positioning plate includes:

[0011] Two sector-shaped first plate bodies, which are sleeved on the natural gas pipeline, and a sector-shaped second plate body is coaxially arranged on the outer side of the first plate body, and the second plate bodies are detachably connected.

[0012] Furthermore, in the leakage detection device for natural gas pipeline transportation, connecting plates are respectively arranged on both sides of the second plate body, and the adjacent two connecting plates are detachably connected.

[0013] Further, in the gas pipeline transportation air leakage detection device, the driving mechanism includes:

[0014] A threaded rod rotatably arranged between the two second plate bodies and in transmission connection with a reduction motor arranged on one of the positioning plates;

[0015] A moving block connected to the moving ring. The moving block is provided with a threaded through hole and is threadedly connected to the threaded rod through the threaded through hole;

[0016] At least one limiting rod arranged between the two second plate bodies. The limiting rod penetrates through the moving ring and is slidably connected thereto.

[0017] Further, in the gas pipeline transportation air leakage detection device, two annular cleaning rings are arranged at intervals on the inner side of the moving ring, and the detection probe is located between the two cleaning rings.

[0018] The gas pipeline transportation air leakage detection device of the present utility model drives the moving ring to perform a linear reciprocating motion on the gas pipeline through the driving mechanism, and the air leakage condition of the gas pipeline is detected in real time by multiple detection probes on the moving ring, ensuring that any leakage in the gas pipeline can be detected in a timely manner.

[0024] The following further describes the present utility model in detail with reference to the drawings, so that those skilled in the art can implement it according to the description in the specification.

[0025] It should be noted that in the description of the present utility model, the orientation or positional relationship indicated by the terms "lateral", "longitudinal", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings.

[0026] Figures 1-4 A gas pipeline transportation leakage detection device provided by an embodiment of the present utility model includes:

[0027] Two positioning plates 1, which are sleeved on the gas pipeline at intervals;

[0028] A driving mechanism, which is arranged on the two positioning plates 1;

[0029] A moving ring 2, which is sleeved between the two positioning plates 1 and is connected to the driving mechanism, and the driving mechanism drives the moving ring 2 to move between the two positioning plates 1;

[0030] A plurality of detection probes 3, which are evenly distributed inside the moving ring 2;

[0031] A controller, which is electrically connected to the detection probes 3.

[0032] In this embodiment, the two positioning plates 1 are respectively fixed on the gas pipeline, and a moving ring 2 is arranged between them. The driving mechanism is fixed by the positioning plate 1, and the driving mechanism drives the moving ring 2 to move between the two positioning plates 1. A plurality of detection probes 3 are arranged inside the moving ring 2. The detection probes 3 adopt existing gas sensors. The detection ranges of the plurality of detection probes 3 are connected to present a ring shape, so as to improve the driving of the driving mechanism to drive the moving ring 2 to move. Thus, the gas pipeline can be detected by the detection probes 3, whether the pipeline leaks is detected and sent to the controller. The controller is communicatively connected to the server or the mobile client through a wireless communication module, which is convenient for the staff to remotely obtain the detection result. When leakage occurs, it can be processed in time.

[0033] Preferably, as another embodiment of the present utility model, the positioning plate 1 includes:

[0034] Two sector-shaped first plate bodies 4, which are sleeved on the gas pipeline. A sector-shaped second plate body 5 is coaxially arranged outside the first plate body 4, and the second plate bodies 5 are detachably connected.

[0035] In this embodiment, connecting plates 6 are respectively arranged on both sides of the second plate body 5, and the adjacent two connecting plates 6 are detachably connected. Such asFigures 1-2 As shown in the figure, holes are drilled in the connecting plate 6, and bolts are arranged in the holes. By tightening the nuts on the bolts, the two connecting plates 6 can be fixed. The two ends of the two second plate bodies 5 are respectively fixed, and the two first plate bodies 4 can be fixed on the natural gas pipeline.

[0036] Preferably, as another embodiment of the present invention, the driving mechanism includes:

[0037] A threaded rod 7, which is rotatably arranged between the two second plate bodies 5 and is in transmission connection with a reduction motor arranged on one of the positioning plates 1;

[0038] A moving block 8, which is connected to the moving ring 2. The moving block 8 is provided with a threaded through hole and is threadedly connected to the threaded rod 7 through the threaded through hole;

[0039] At least one limiting rod 9, which is arranged between the two second plate bodies 5. The limiting rod 9 penetrates through the moving ring 2 and is slidably connected to it.

[0040] In this embodiment, the reduction motor drives the threaded rod 7 to rotate, and the threaded rod 7 drives the moving block 8 to rotate. However, under the limitation of the limiting rod 9, the moving block 8 moves linearly along the threaded rod 7, thereby driving the moving ring 2 to reciprocate along the length direction of the natural gas pipeline.

[0041] Preferably, as another embodiment of the present invention, two annular cleaning rings 10 are arranged at intervals on the inner side of the moving ring 2, and the detection probe 3 is located between the two cleaning rings 10.

[0042] In this embodiment, cleaning rings 10 are respectively arranged on both sides of the multiple detection probes 3. The surface of the natural gas pipeline is cleaned by the cleaning rings 10, and the dust on the surface of the natural gas pipeline is reduced to affect the detection accuracy of the detection probe 3.
