A device for cleaning the inner wall of an adaptive curved pipe

Abstract

The invention discloses an adaptive cleaning device for the inner wall of an elbow, which belongs to the technical field of cleaning the inner wall of the pipe. According to the size of the pipe diameter of the elbow, an appropriate amount of gas is injected into the cleaning bag to make the cleaning bag contact and squeeze the inner wall of the pipe. The pulling of the pull rope by the traction device makes the pushing force of the sliding ball inside the cleaning bag, and under the cooperation of the spiral channel and the soft sliding rod, adapt to the bending of the elbow, and perform a rotation-forward movement inside the elbow, and the elbow The inner walls are squeezed and rubbed against each other to effectively remove impurities and dirt on the inner wall of the elbow. Moreover, because the expanded cleaning bag has a certain elastic deformation function, it can not only adapt to the bending of the elbow, but also make corresponding deformation according to the change of the pipe diameter. Therefore, the present invention can realize the process of cleaning the inner wall of the reducing elbow to a certain extent.

Description

technical field [0001] The invention relates to the technical field of pipe inner wall cleaning, and more specifically relates to an adaptive elbow inner wall cleaning device. Background technique [0002] Pipeline has a wide range of applications and various types. It is a system, including: connected equipment and facilities, pipes, valves, pipe fittings, supports and hangers, etc. It is one of the most important transportation systems together with aviation, highways, and railways. [0003] After the pipeline has been used for a long time, some dirt will accumulate on the inner wall of the pipeline. Because the inner wall of the pipeline is special, if the dirt accumulates for a long time, it will oxidize and form acidic substances, which will easily cause corrosion and rust on the inner wall of the pipeline. [0004] At present, there is no suitable cleaning device for cleaning the inner wall of the pipeline to clean the inner wall of the pipeline, and it is generally wa...

Problems solved by technology

[0003] After the pipeline has been used for a long time, some dirt will accumulate on the inner wall of the pipeline. Because the inner wall of the pipeline is special, if the dirt accumulates for a long time, it will oxidize and form acidic substances, which will easily cause corrosion and rust on the inner wall of the pipeline.

[0004] Nowadays, there is no suitable cleaning device for cleaning the inner wall of the pipeline to clean the inner wall of the pipeline. Generally, it is washed by a high-pressure water gun

However, for some curved pipes with variable shapes, there are many blind spots in the inner wall of the pipe, and it is difficult to make the water flow fully act on the inner wall of the elbow by using the flushing method, and there are problems such as insufficient cleaning force and incomplete cleaning area
