The present invention relates to a hollow cylindrical cleaning device for removing the internal fixed foreign matter of the hollow cylinder, such as water and sewage pipe, more specifically to effectively remove the fixed foreign matter in the hollow cylinder, in particular, the fluid pressure rather than electric power Since there is no structure, there is no fear of electric malfunction due to dust and moisture generated during actual operation, and the overall structure is simplified, and the present invention relates to a hollow cylindrical cleaning device which reduces the device manufacturing cost and extends the service life of the device.

Hollow cylinders, such as water and sewage pipes, for example, steel pipes, concrete structures, or various types of hollow cylinders, such as synthetic resin pipes are used in the various types of foreign matter, such as rust or scale Foreign matter such as scale is generated.

Or, foreign matter contained in the fluid flowing inside is attached to the inner surface of the hollow cylinder, the foreign matter in such a hollow cylinder is easy to adhere over time, once fixed, the situation is very difficult to remove.

However, in the case of scales such as rust or scale among fixed foreign matters in the hollow cylinder body, the corrosion of steel pipes, which are most often used for piping, is accelerated and the life thereof is shortened. This can cause serious problems such as leakage of internal fluid.

And, even in the case of concrete structures or plastic pipes, but not steel pipes, the scale will cause corrosion in the metal joints of the structures or pipes and consequently shorten the life as steel pipes.

In addition, these various types of fixed foreign matters may impede the flow of the fluid flowing inside the hollow cylinder and, in severe cases, cause excessive pressure on the localized portion of the hollow cylinder, eventually causing damage to the hollow cylinder itself. In particular, such sticking foreign matters cause other problems that become pollutants that contaminate fluids flowing in the hollow cylinder, for example, tap water.
