Description

Technical Field

[0001] The utility model mainly relates to the field of mining pipelines, and in particular to a mining pipeline leakage detection device. Background Art

[0002] As the primary energy source for economic development, coal is known as black gold. Its development and mining have provided tremendous impetus for economic development and social progress. In the early days of coal mining, there were no gas extraction or ventilation systems, relying solely on natural ventilation. As mining progressed, natural ventilation could no longer meet production safety requirements, leading to the development of forced ventilation systems. To prevent dust storms caused by excessive dust concentrations during mining and transportation, water supply and drainage systems were used underground in coal mines, leading to the development of coal mine pipelines.

[0003] Early coal mine pipelines primarily consisted of cast iron and steel pipes. Due to the complex geological conditions underground in coal mines, acidic and other corrosive gases can severely corrode pipeline systems, ultimately leading to failure. In recent decades, countries around the world have adopted various methods to mitigate pipeline corrosion, including cathodic protection, plating, and coating, which have, to a certain extent, played a positive role in protecting pipelines.

[0004] With the development of science and technology and the economy, new technologies have been applied to underground coal mine pipes, especially plastic pipes. This has led to rapid development of underground coal mine pipes, and the emergence of many new products with excellent performance, light weight, and easy installation and use. These include glass fiber reinforced plastic sand-filled pipes and solid-wall polyethylene flame-retardant and antistatic pipes.

[0005] During the operation of the specific embodiment, the inventors found the following defects:

[0006] Because mining pipelines transport high-pressure liquids or gases for a long time, and debris falls inside the mine, the debris and the pipeline structure can easily cause pipeline leakage. It is necessary to use a detection device to detect the pipeline leakage point. However, the pipeline is set in an arc shape, so only the leakage location can be determined, and the exact leakage point cannot be determined.

[0007] It should be noted that the above content belongs to the technical knowledge scope of the inventor. Since the technical content in this field is vast and too complicated, the above content of this application does not necessarily constitute prior art. Utility Model Content

When it is necessary to detect the leakage point of the mining pipeline, the inflatable rings 104 on the inner sides of the two fitting rings 101 are fitted with the mining pipeline, and then the two fitting structures 1 are fixed to the outer wall of the mining pipeline through the connecting structure 3. Thereafter, air is inflated into the interior of the inflatable ring 104 through an air pump to expand the inflatable ring 104. Then, the inflatable ring 104 is fitted with the outer wall of the mining pipeline to seal the gap between the mining pipeline and the fitting ring 101, and the spacer sealing plate 105 is fitted with the outer wall of the mining pipeline.
