Description

Technical Field

[0001] This invention relates to the field of gas pipeline construction technology, and in particular to a gas pipeline cleaning device for gas pipeline construction. Background Technology

[0002] In gas pipeline construction, a pipeline cleaning device is a key tool used to ensure the cleanliness and smooth flow of gas inside the pipeline, thereby ensuring the safety and efficiency of gas delivery. A pipeline cleaning device typically consists of a series of tools and equipment, and the appropriate cleaning device can be selected based on the specific pipeline size, material, and construction environment.

[0003] A gas pipeline cleaning device, disclosed in CN213162278U, belongs to the field of gas pipeline construction technology. The device includes a cleaning ball and a traction ball, connected by a traction rope. The diameter of the cleaning ball is larger than the inner diameter of the pipeline to be cleaned, while the diameter of the traction ball is smaller. The cleaning ball comprises a spherical double-layered airbag and a liquid-retaining sponge block inside the airbag. The sponge block contains cleaning fluid, and its four corners are arc-shaped to match the airbag. An adhesive layer is provided at each corner. This design utilizes the cleaning layer, which is fitted over the airbag, to clean the inner wall of the pipeline. The cleaning ball is pulled in from one end of the pipeline and out from the other using the traction rope, completing the cleaning process. The device is simple in structure, easy to operate, and significantly improves the efficiency of gas pipeline cleaning.

[0004] The aforementioned pipeline cleaning device uses a sponge ball as a cleaning tool, which can be damaged due to friction with the gas pipeline during actual use. As a consumable, it is inconvenient to replace. Furthermore, during the cleaning process, dirt inside the gas pipeline will accumulate on one side of the cleaning ball's forward direction, affecting the cleaning effect and efficiency, thus limiting its practicality. Therefore, a new type of pipeline cleaning device for gas pipeline construction is provided to solve the above problems. Summary of the Invention
