[0002] In the field of pipeline maintenance and detection, the collection and proper storage of pipeline foreign matters are crucial for accurately judging the pipeline condition and formulating effective maintenance strategies. The device integrating filtration and collection can help maintenance personnel accurately obtain samples of foreign matters in the pipeline, providing accurate and reliable basis for subsequent analysis and detection, which helps maintenance personnel to deeply understand the operation condition of the pipeline and find the root cause of potential problems, so as to formulate a more scientific and reasonable maintenance scheme, further improve the operation efficiency and safety of the pipeline system. In the pipeline maintenance and detection work, it is a very practical and indispensable tool. Therefore, a pipeline foreign matter storage device is particularly needed.

[0003] However, the existing pipeline foreign matter storage device generally adopts a complex mechanical connection structure such as bolt fastening and flange connection in the installation and fixing link, which often needs to be operated in multiple procedures with the help of special tools such as wrenches and sleeves. Not only does it greatly increase the installation time and labor cost, but also easily leads to sealing failure due to errors in the assembly process, affecting the operation stability of the equipment. After completing the foreign matter collection task, the disassembly process is also tedious and long, and needs to be operated in reverse with the help of tools again. Frequent disassembly and assembly can easily cause part wear and fatigue, significantly shorten the service life of the equipment, and increase the operation and maintenance cost.
