Self-rotating pipeline cleaning device

The invention discloses a self-rotating pipeline cleaning device which comprise a water feeding mechanism, a sweeping mechanism and a pre-sweeping mechanism. The water feeding mechanism is used for spraying water on the inner wall of a pipeline. The pre-sweeping mechanism is used for sweeping bricks, stones, ash blocks and other large-size sundries. The sweeping mechanism successfully sweeps dust and other small-size sundries. Under the effect of counter-acting force of water spray, a cylinder can rotate autonomously for washing through a brush. Compared with the prior art, the self-rotating pipeline cleaning device improves work efficiency, reduces cleaning cost, has strong applicability, is applicable to cleaning of pipes of various models by changing its size, meets use requirements of customers, and can be popularized and used in industries conveniently.
