Description

Technical Field

[0001] The utility model relates to the technical field of mechanical engineering, and particularly relates to an underground pipeline leakage monitoring and alarming device. Background Technique

[0002] In urban construction and industrial production, underground pipelines play a crucial role, such as transporting various fluid media such as water, oil, and gas. However, due to the long-term exposure of underground pipelines to complex environments and being affected by factors such as corrosion, aging, geological changes, and external construction, pipeline leakage accidents occur frequently.

[0003] Traditional underground pipeline leakage detection methods have many deficiencies. On the one hand, the detection means are not sensitive enough to detect small leakage situations in a timely manner, resulting in the gradual deterioration of leakage problems without being noticed, causing waste of resources and environmental pollution, and even potentially triggering safety accidents. On the other hand, the installation process of traditional detection equipment is complex and cumbersome, consuming a large amount of time and labor costs, which is not conducive to rapid deployment and emergency response.

[0009] The beneficial effects of the present utility model are as follows:

[0010] 1. By providing a detection component, the present utility model can sense the change in pressure inside the pipeline.

[0012] 3. By providing a diversion ring, the diversion holes on the diversion ring not only facilitate the flow of water in the pipeline but also guide the water flow to the fixed frame, ensuring that the leaked water can smoothly enter the transparent shell for alarm, improving the working stability and reliability of the device.

[0013] 4. By providing a quick-connection component, the present utility model can quickly install the device onto the pipeline. The operation is simple and convenient, greatly improving the installation efficiency and saving installation time and labor costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] Please refer to Figure 1 - Figure 6 , the present utility model provides a technical solution: an underground pipeline leakage monitoring and alarm device, including: a fixed cylinder 1; a quick-connection component 2, the outer wall of the quick-connection component 2 is fixedly connected to the outer wall of the fixed cylinder 1, and two groups of quick-connection components 2 are provided; a detection component 3, the outer wall of the detection component 3 is fixedly connected to the inner wall of the fixed cylinder 1; the detection component 3 includes a flow guide ring 31, a flow guide hole 32 is opened in the wall of the flow guide ring 31, and the flow guide holes 32 are annularly arranged along the central axis of the flow guide ring 31, the outer wall of the fixed cylinder 1 is fixedly connected to a fixed frame 33, a sealing ring is fixed on the top of the fixed frame 33, and the fixed frames 33 are annularly arranged along the central axis of the fixed cylinder 1, the inner wall of the fixed frame 33 is slidably connected to a mounting plate 36, the inner wall of the mounting plate 36 is fixedly connected to a sealing plate 37, the top of the mounting plate 36 is fixedly connected to a transparent shell 38, the material of the transparent shell 38 is a transparent material, the outer wall of the fixed frame 33 is rotatably connected to a limit disk 35, and the outer wall of the flow guide ring 31 is fixedly connected to the inner wall of the fixed cylinder 1.

[0024] The outer wall of the limit disk 35 is in contact with the outer wall of the mounting plate 36, a drainage groove 34 is opened in the wall of the flow guide ring 31, and the drainage grooves 34 are annularly arranged along the central axis of the flow guide ring 31, the quick-connection component 2 includes a mounting seat 22, a positioning ring 25 is fixedly connected to the outer wall of the mounting seat 22, the position of the pipeline is restricted by the positioning ring 25, a hoop 21 is fixedly connected to the outer wall of the mounting seat 22 through a fixed shaft, and the inner wall of the hoop 21 is slidably connected to a bolt 23.

[0025] The outer wall of the mounting base 22 is fixedly connected to the outer wall of the fixed cylinder 1. The outer wall of the bolt 23 is threadedly connected with a limit button 24. By squeezing the clamping hoop 21 with the limit button 24, the position of the pipeline can be restricted by the clamping hoop 21. The outer wall of the limit button 24 is slidably connected to the outer wall of the clamping hoop 21.

[0026] Working principle:

[0027] During use, first install the detection and alarm device on the pipeline. Just cut off the pipeline and connect the two cut ends of the pipeline to the quick-connect components 2 at both ends of the detection and alarm device. The detection and alarm device can be quickly installed on the pipeline through the quick-connect components 2. Then, the detection work on the pipeline can be carried out. When the pipeline leaks, the pressure in the pipeline will decrease instantly, triggering the detection component 3 on the fixed cylinder 1, and the detection component 3 will prompt the personnel that the pipeline has leaked, so as to check the pipeline.

[0028] When using the quick-connect component 2, just slide the inner wall of the pipeline along the outer wall of the positioning ring 25 to the mounting base 22. After the pipeline wraps the positioning ring 25 and abuts against the mounting base 22, the limit button 24 on the bolt 23 can be rotated. By pressing the clamping hoop 21 with the limit button 24, the pipeline can be tightened by the clamping hoop 21, and the pipeline can be fixed on the positioning ring 25.

[0029] When the pipeline leaks, the pressure in the pipeline will decrease instantly. This is because the leakage point will cause the liquid in the pipeline to flow out, resulting in a decrease in the liquid volume in the pipeline, thus causing the pressure to drop. The transparent shell 38 in the detection component 3 is relatively isolated from the outside under normal circumstances, and the pressure inside it remains relatively stable. Therefore, when the pressure in the pipeline becomes smaller, that is, the pressure at the fixed frame 33 becomes smaller, there is a pressure difference on both sides of the sealing plate 37. The sealing plate 37 is made of nitrile rubber and can maintain the sealing of the pipeline within a certain pressure range. However, when the pressure difference on both sides exceeds its bearing limit, the sealing plate 37 will be damaged, allowing the water in the pipeline to enter the drainage groove 34 along the drainage holes 32 on the diversion ring 31 and then enter the transparent shell 38 through the drainage groove 34. When there is water flow in it, it can clearly warn the staff that the pipeline has leaked, so as to quickly take inspection and repair measures and effectively reduce the losses caused by leakage.

[0030] When the sealing plate 37 needs to be replaced, just stop the pipeline and rotate the limit disc 35 so that the groove on the limit disc 35 aligns with the mounting plate 36, and the mounting plate 36 can be slid out of the fixed frame 33. Then, the mounting plate 36 and the transparent shell 38 can be replaced together. The drainage holes 32 on the diversion ring 31 not only facilitate the water flow in the pipeline to pass through, reducing the resistance to the water flow, but also can effectively guide the water flow into the fixed frame 33 when leakage occurs, ensuring that the leaked water can smoothly enter the transparent shell 38 for alarm.

All other embodiments obtained by those of ordinary skill in the art and related fields based on the embodiments of the present utility model without creative efforts shall fall within the scope of protection of the present utility model.
