Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a rotating cleaning device used for cleaning pipes such as drain pipes in apartments, building piping equipment, etc.

[Conventional technology]

Conventionally, the head at the distal end of a high-pressure hose used in a rotating cleaning device is composed of a nozzle, a snake wire, and a flexible guide, which are connected in a straight line.

[Problem that the invention seeks to solve]

When the high pressure hose is advanced along the horizontal pipe, the high pressure hose travels along the bottom surface of the horizontal pipe. The pressure of the nozzle's high-pressure water jet decreases as it gets closer to the inner wall of the pipe, so higher pressure and a larger amount of water are required to crush hardened solids adhering to the upper part of the pipe. It was not possible to clean the inside evenly.

The present invention aims to eliminate the above-mentioned defects.

[Means to solve problems]

In order to achieve the above purpose, a nozzle is provided at the tip of a high-pressure hose, a flexible guide is connected to the tip of the nozzle, high-pressure water is sprayed diagonally backward from the nozzle, and the spraying force provides a propulsive force to the nozzle. In an apparatus for cleaning the inside of a pipe with high-pressure water sprayed from the nozzle, the high-pressure hose is sent into a pipe while rotating the high-pressure hose, and the tip of the nozzle is set relative to the center axis of the high-pressure hose. It is tilted at a predetermined angle.

[Effect]

Therefore, when the high-pressure hose 2 is rotated and advanced into the drainage horizontal pipe, the nozzle 6 turns around the pipe peripheral wall due to the inclination of the tip of the nozzle 6 with respect to the high-pressure hose 2.
The nozzle 6 evenly cleans the peripheral wall of the pipe.

A shaft 34 is installed in a direction perpendicular to the central axis of the connecting rod 30, and the shaft 34 is loosely fitted into the hole of the connecting rod 30. A connecting rod 36 is protruded from the center of the bottom of the guide 32, and a hole 38 is formed at the tip of the connecting rod 36 in a direction that is at an angle of 90 degrees with respect to the direction of the hole in the connecting rod 30. It is set up. Reference numeral 40 denotes a tip guide made of a cylindrical metal member, and a shaft 42 is installed in the vicinity of the open end in a direction perpendicular to the central axis of the guide 40, and the shaft 42 is inserted into the hole of the connecting rod 36. 38 is loosely fitted. The respective guides 18, 26, 32, 40 are connected to the shafts 20, 2 with respect to the connecting rods 14, 22, 30, 36.

46 is a drain pipe.

Next, the operation of this embodiment will be explained.

The drain pipe 46 is cleaned by spraying high-pressure water pressurized by a pump into the injection hole 8 of the nozzle 6 attached to the tip of the hose 2.
This is done by injecting from the At the same time, the high-pressure water injected from the nozzle 6 crushes and peels off the deposits inside the pipe, and at the same time, the nozzle 6 moves forward in the pipe by the propulsive force of the high-pressure water that is injected from now on. In the horizontal pipe 46a,
As shown in FIG. 3, by rotating the high-pressure hose 2 within the pipe, the water jetted from the nozzle 6 hits the inner wall of the pipe obliquely, and the nozzle 6 rotates around the peripheral wall of the pipe. In the vertical main pipe 46b, the nozzle 6 rotates by rotating the high-pressure hose 2 at a constant speed, and the jet water sprayed from the plurality of injection holes 8 of the nozzle 6 evenly sprays the inner wall of the pipe and efficiently moves inside the pipe. Wash. Incidentally, the snake wire can also be omitted as shown in FIG. 6.

〔effect〕

As described above, in the present invention, the nozzle is inclined with respect to the high-pressure hose, so when the high-pressure hose is rotated, the nozzle rotates along the circumference of the pipe, and the high pressure of the water jetted from the nozzle removes the hard deposits on the pipe wall. It can be pulverized in a single section, with no loss of injection pressure or water volume.
It has the effect of efficiently and completely cleaning the inside of the pipe.
