When a high-pressure hose is let out and the nozzle is advanced along a water pipe, the tip of the flexible guide may hit a foreign object firmly attached to the pipe wall. In this case, since the nozzle ejects high-pressure water backward, the ejected water does not directly hit the foreign object, making it impossible to crush the foreign object. Therefore, the free guide is blocked by foreign objects and cannot move forward.

is connected to one end of. Injection holes 12 and 14 for reverse injection formed in the nozzle 4 communicate with the inside of the high-pressure hose 2 through an axial hole 16 of the nozzle 4 and an axial hole of the hose joint portion 4a. A protruding shaft 20 is provided at the tip of the nozzle 4 and has a through hole 18 extending over its entire length and communicating with the shaft hole 16 . Reference numeral 6 denotes a flexible guide made of a hollow spherical metal member, and an opening is formed at the rear of the guide. The flexible guide 6 is rotatably fitted into the hemispherical portion 20a of the protruding shaft 20. An ejection hole 8 is formed at the tip of the free guide 6, and the hole 8 communicates with a square hole 22 bored in the inner wall of the tip of the free guide 6. A square convex portion 20b is formed at the tip of the protruding shaft 20 so as to face the square hole 22 and fit therein. The high pressure hose 2 is connected to a known terminal device 1, as shown in FIG.
0 to the pump outlet. The terminal device 10 is equipped with a device for controlling an on-off valve for high-pressure water, feeding out the high-pressure hose 2 wound around a drum, winding the high-pressure hose 2 around the drum, and rotating the high-pressure hose 2, that is, rotating the drum. It is set up. In addition, in the figure, 24 is a drain pipe. In this embodiment, the flexible guide is made of one hollow spherical metal member, but as shown in FIG.

とする。 The drain pipe 24 is cleaned by injecting high-pressure water pressurized by a pump from the injection holes 12 and 14 of the nozzle 4 attached to the tip of the high-pressure hose 2, as shown in FIG. At the same time, the nozzle 4 is moved forward in the pipe by the propulsive force of the high-pressure water that is sprayed in the opposite direction while crushing and peeling off the deposits inside the pipe by the high-pressure water that is sprayed from the nozzle 4 in the opposite direction. At this time, the high-pressure water fills the interior of the flexible guide 6 through the through hole 18, and the outer wall surface of the hemispherical portion 20a comes into close contact with the inner wall surface of the flexible guide 6 near the rear opening. This prevents water from flowing out from the contact area between the flexible guide 6 and the hemispherical part, and the jet water coming out of the jet hole 8 at the tip of the flexible guide 6 crushes the deposits in the front of the pipe, and this direct jet water The inside of the pipe is cleaned with the reverse jet water from the nozzle 4. When the tip of the flexible guide 6 hits an obstacle, the contact between the sliding portion of the flexible guide 6 and the hemispherical portion 20a breaks down, and water flows from this portion. At this time, a pressure drop occurs inside the flexible guide 6, and the protruding shaft 20 moves forward due to the pushing force of the high-pressure hose 2, so that the convex portion 20b engages with the square hole 22. As a result, the rotation of the high-pressure hose 2 is transmitted to the flexible guide 6, causing a swinging phenomenon in the flexible guide 6, and when the flexible guide 6 is in contact with a protrusion at the joint of the pipe, it comes off from this protrusion, and the nozzle 4 to enable progress.
本発明は上述のごとく、自在ガイドの先端から
高圧水を噴出させるようにしたので、管内の前方
付着物を直射粉砕することができ、効率的に管内
を洗浄することができる効果が存する。
As described above, in the present invention, high-pressure water is ejected from the tip of the flexible guide, so it is possible to directly crush the deposits on the front inside the pipe, and there is an effect that the inside of the pipe can be efficiently cleaned.
