対する破壊力が乏しい。(B) Conventional technology A conventional cleaning device will be explained based on a drawing.In order to rotate the nozzle, which is attached to the end of the hose, along the circumferential direction inside the pipe, the spring attached to the end of the nozzle is bent. , the hose rotation drive device (18) shown in Figure 5 that rotates the entire hose is used, but if the hose is inserted into a pipe with many bends, the rotational speed will vary by 2 to 3 times depending on the frictional resistance between the pipe and the hose and other factors. If the nozzle passes through more than one bend, the nozzle will not turn along the circumferential direction inside the pipe. In addition, in order to rotate a hose over 10 meters in length, the hose must have the necessary hardness for rotation, which makes it difficult to insert it into narrow pipes with many bends. In addition, in other technologies, the nozzle (27) in Fig. 7 only rotates around the axis of the nozzle, and especially in horizontal piping, the distance from the nozzle hole outlet to the deposits on the upper part of the pipe is long. Therefore, it has poor destructive power against deposits. Further, the nozzle shown in FIG. 6 simply injects fluid from nozzle holes radially formed from the axis of the nozzle, and has less destructive power against deposits than the device shown in FIG. 7.
（ハ）発明が解決しようとする問題点

することも目的としている。(c) Problems to be solved by the invention However, in such a cleaning device, when the piping is placed horizontally or the piping has many bends, the nozzle hole outlet is subject to rotational movement along the circumferential direction inside the pipe in the vicinity of deposits. Cleaning is insufficient because the equipment is not cleaned properly. In particular, in the apparatus shown in FIG.
) is required, and the hose must be hard enough to transmit rotation. This invention makes the hose flexible so that it can be inserted into narrow pipes with many bends, and the nozzle always performs a turning motion along the circumferential direction of the pipe even in the pipe with many bends, so that the flow rate and pressure of the fluid can be adjusted. It is also intended to be smaller in size than conventional devices, and to eliminate the need for a rotary drive device (18) that rotates the hose.

Further, in order to rotate the nozzle around the axis of the nozzle, it is fixed to the rotating part of the rotation medium (2), and the hose is fixed to the fixed part of the rotation medium (2). and the nozzle form a flow path. In addition, in order to always contact the inner wall regardless of the upper part of the inner wall of the horizontal piping, the nozzle hole that is drilled in the radial direction from the axis of the nozzle is set as the nozzle hole outlet in one half of the cross section perpendicular to the axis of the nozzle.

ある。At the same time, fluid is ejected from a nozzle hole (7) formed radially from the axis of the nozzle (1), and the reaction force moves the nozzle (1) in the direction of being pressed against the inner wall of the pipe. The nozzle (1) turns along the circumferential direction of the inner wall of the tube due to this rotational movement and the reaction force in one direction. As a result, dirt and deposits inside the pipe are cleaned by the destructive force of the fluid ejected from the nozzle hole.
