水管内に送り出し、管内壁を洗浄する。In the above structure, the high-pressure water is jetted obliquely rearward of the inner wall of the drain pipe from the plurality of jet holes of the nozzle, and the jet force generates a propulsive force in the nozzle, while the terminal device or the driving device produces high pressure. The high pressure hose is fed into the drain pipe while rotating the hose, and the inner wall of the pipe is washed.

て非常に高価であるなどの欠点があった。However, in the above embodiment, in order to rotate the nozzle inside the pipe, it is necessary to rotate the high-pressure hose at a constant speed with a terminal or a driving device. Therefore, as the length of the high pressure hose becomes longer or the number of bent portions of the pipe becomes larger, the rotational force becomes more problematic, and the apparatus itself is very expensive as a whole.

離することができる配管洗浄装置を得るにある。"Problems to be Solved by the Invention" In view of the drawbacks of the conventional techniques as described above, the present invention needs to rotate a high pressure hose using a terminal device or a drive device in order to impart a rotational force to a nozzle. Therefore, even if there are two or more bent parts of the pipe, these bent parts do not affect the rotational force of the nozzle itself and the turning force of the nozzle with respect to the pipe, and the cleaning range is expanded. In addition, the cleaning device is inexpensive, and further, the nozzle can be turned along the inner peripheral wall of the pipe or according to the bend of the pipe as desired to crush and remove the deposits in the pipe in a well-balanced manner. To get.

球体13が固定的に取付けられている。12 is fixedly attached to the tip of the nozzle 8, and when the nozzle 8 is rotated by the jet reaction force, the nozzle is fixed to the inner wall of the pipe 1.
It is an elongated nozzle guide member that abuts and guides the inner peripheral wall of the pipe so as to be wound along 2a. As the elongated nozzle guide member 12, for example, a rubber tube, a vinyl tube, a metallic wire rod, or the like may be used, but it is desirable that the material itself has an elastic force in consideration of the forward / backward movement of the bent portion of the tube. . Also, the elongated nozzle guide member 12 is
As shown in the drawing, the tip portion 12a is bent and formed so as to deviate from the center line of the shaft hole 11 of the nozzle 8. Further, a metallic sphere 13 is fixedly attached to the tip portion 12a so that the elongated nozzle guide member 12 and the like can be easily advanced following the bent portion of the pipe.

Wash water flows into. At this time, the nozzle 8 slightly slides toward the tip side due to the pressure of the fluid, but the tubular blade fixing body 10a fixedly attached to the insertion end of the tubular connecting portion 8a of the nozzle abuts on the plate 7. It does not come off from the nozzle support 3.

It is injected from 9a, 9b, 9c, 9d. At this time, the nozzle 8 is rotated in the circumferential direction by the jet reaction force. Then, this rotation power is a blade that receives the fluid energy that tries to pass through the shaft hole 11.
The bearing 5 that supports the nozzle 10 and the nozzle 8 further increases the height.

The tip portion 12a or the spherical body 13 of the tube 1 is always in contact with the inner peripheral wall 1a of the tube 1, whereby the nozzle 8 is guided and runs along the inner peripheral wall 1a of the tube 1 as shown in FIG. Therefore, even if the pipe to be cleaned has a larger diameter than that shown in FIG. 1, the nozzle 8 rotates without separating or significantly separating from the inner peripheral wall of the pipe. Further, since the injection hole 9 is obliquely directed to the inner peripheral wall of the pipe simultaneously with the rotation, the nozzle 8 advances due to the propulsive force.

That is, the blade fixing member and the blade are not provided at the insertion end of the tubular connecting portion 8a of the nozzle 8A, while the ring 15 as a stopper member that is screwed to the insertion end and abuts the bearing plate 7 is provided. The point is that it is provided integrally with the nozzle 8A. Further, the tip portion 12a of the elongated nozzle guide 12A is the same in that it is bent so as to be displaced from the center line of the shaft hole 11 of the nozzle, but the tip portion 12a is provided with a metallic sphere.
