Description

Technical Field

[0001] The utility model relates to the technical field of thermal pipeline cleaning, in particular to a pipe cleaning device. Background Art

[0002] Thermal pipelines are also called thermal pipe networks. As an important part of the urban heating system, thermal pipe networks undertake the important task of transporting heat energy to various users. However, with the long-term use of the pipelines, scale, rust and other impurities will inevitably adhere to the inside. The accumulation of these impurities will not only affect the circulation of water in the pipelines, reduce the heating efficiency, but also may cause pipeline blockage;

[0003] Pipe cleaning usually requires disassembling the pipes at various locations and then cleaning them step by step. In recent years, some pipe cleaning devices have appeared on the market. Most of these devices use brushes and scrapers to clean the pipe walls. However, these devices still have some problems in actual use. First of all, brushes and scrapers are key components of cleaning devices and have limited service life. During use, due to friction with the pipe wall and impact of impurities, the bristles and scrapers are easily worn or damaged. Once these components are damaged, the cleaning effect will be greatly reduced. However, traditional cleaning devices are often not easy to replace brushes and scrapers. In addition, impurities cleaned by brushes and scrapers often accumulate at the bottom of the pipe and are difficult to discharge by themselves. Therefore, we propose an in-pipe cleaning device.
