在ガイドは異物に進行を阻止され、前に進むことができ
なくなる。When the high-pressure hose is let out and the nozzle is advanced along the drain pipe, the tip of the flexible guide may hit a foreign object firmly attached to the pipe wall. In this case, since the nozzle is ejecting high-pressure water backwards, the ejected water does not directly hit the foreign object and cannot crush the foreign object. Therefore, the flexible guide is blocked by the foreign object and cannot move forward. become unable to do so.

の構造は第1図に示す構造と同一である。In FIG. 1, 4 is a nozzle, and a hose joint portion 4a formed therein is connected to one end of the high pressure hose 2. In FIG. Injection hole 1 for reverse injection formed in nozzle 4
2 and 14 communicate with the inside of the high-pressure hose 2 through the shaft hole 16 of the nozzle 4 and the shaft hole of the hose joint portion 4a. A projecting shaft 20 is provided at the tip of the nozzle 4 and has a through hole 18 that communicates with the shaft hole 16 extending through its entire length. 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. Said high pressure hose 2
is connected to the outlet of the pump via a known terminal 10, as shown in FIG. 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 composed of one hollow spherical metal member, but as shown in FIG.
A hollow spherical metal member 32 is rotatably fitted into the hemispherical portion 30 of this protrusion #28, and the plurality of hollow spherical metal members form a plurality of flexible guides 6.
may be configured. The ejection hole 34 at the tip of the member 32 is a through hole 36. .. It communicates with the shaft hole 16 of the nozzle 4 via 18. Square holes 36, 38 are formed in the members 32, 26,
Each of the protruding shafts 28, 20 is formed with a protrusion, the structure of which is the same as that shown in FIG.
次に本実施例の作用について説明する。Next, the operation of this embodiment will be explained.
排水管24の洗浄は、第5図に示すように、ポンプで加
圧した高圧水を高圧ホース2の先端に取り付けたノズル
4の噴射孔12.14から噴射させることにより行う。The drain pipe 24 is cleaned by injecting high-pressure water pressurized by a pump from the injection holes 12, 14 of the nozzle 4 attached to the tip of the high-pressure hose 2, as shown in FIG.

し、半球形部20aの外壁面は自在ガイド6の後部開口
部分の近傍内壁面に密着する。これにより。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. Due to this.

進行を可能とする。Water no longer flows out from the contact area between the flexible guide 6 and the hemispherical tip, and the water jetted out from the spout hole 8 at the tip of the flexible guide 6 crushes the deposits in the front of the pipe, and this direct jetted water and the nozzle 4 Clean the inside of the pipe with reverse jet water. When the tip of the flexible guide 6 hits an obstacle, the flexible guide 6 and the hemispherical part 20a
The adhesion between the joints breaks down and water flows from this area. When a pressure drop occurs inside the flexible guide 6, the pushing force of the high-pressure hose 2 causes the protruding shaft 2o to move forward and the convex portion 20b engages with the square hole 22, thereby allowing the high-pressure hose 2 to rotate freely. 6, a swinging phenomenon occurs 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, allowing the nozzle 4 to advance.
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.
