Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pipe cleaning apparatus used for cleaning drainage pipes (pipes) of condominiums, buildings, factories, etc. using high pressure water.

[0002]

2. Description of the Related Art Conventionally, an example of actual rotation of a pipe cleaning apparatus of this type is disclosed in Japanese Patent Laid-Open No. 1-315379. This actual example was proposed by the present inventor,
Basically, a cylindrical nozzle support to which the insertion end of the hose is attached, and an unbalanced force that is rotatably supported by this nozzle support via a mini bearing and is directed to the inner wall of the pipe. It is composed of a nozzle having an injection hole and an elongated nozzle guide member integrally attached to the nozzle and guiding the nozzle along the inner peripheral wall of the pipe.

However, in the above structure, since the guide member provided on the nozzle support is elongated,
It is not possible to easily clean the inside of small-diameter pipes or complicated pipes, and because the nozzle rotates via a mini bearing, cleaning water enters between the inner ring and the outer ring, and the nozzle rotatability is improved. However, there was a problem regarding the durability of the cleaning device.

[0004]

In view of the above-mentioned conventional drawbacks, the present invention makes it possible to easily clean the inside of a small-diameter pipe or a complicated pipe, and to arrange the revolving structure along the inner peripheral wall of the pipe. In addition, the revolving structure rotates smoothly with respect to the nozzle support in combination with the water film bearing function, and the nozzle support slides on the inner wall of the pipe to rotate the revolving structure. It is an object of the present invention to provide a pipe cleaning device that does not impose a force on the force and can easily remove or remove deposits attached to the inner wall of the pipe.

[0005]

In the pipe cleaning apparatus of the present invention, a bearing portion is formed on the front end side, a hose is attached on the rear end side, and a main flow path is provided in the axial center direction. It comprises a nozzle support and a cylindrical revolving body that is loosely fitted to the bearing of the nozzle support so as to form a film having the function of a fluid bearing. A groove-shaped fluid reservoir that can communicate with the fluid supply passage formed in the bearing is formed in the circumferential direction, and an unbalanced force injection hole is formed in the revolving structure so as to communicate with the fluid reservoir. A guide portion for guiding the revolving structure along the inner peripheral wall of the pipe is projected at an appropriate portion of the peripheral body portion of the body.

In the above structure, a rotating member (rotating wheel or sphere) for positively rotating the revolving structure so that the bearing function of the water film sufficiently acts may be provided on the outer peripheral portion of the revolving structure. . Further, in the case of positively removing the adhered matter adhering to the inner wall of the pipe, it is desirable to form the end portion of the guide portion into a blade shape or separately provide a blade body.

[0007]

First, the pipe cleaning device is inserted into the pipe, and the pump supplies the cleaning water at a predetermined pressure to the hose. Then,
The wash water flows from the insertion end of the hose into the main channel of the nozzle support.

However, when the washing water flows into the main passage,
By the jets jetted from the first self-propelled jet hole and the fluid supply passage and the jets jetted from the second self-propelled jet hole, respectively, the pipe cleaning device self-propels into the interior of the pipe. To run.

By the way, the cleaning water flowing into the main flow passage is
It passes through the fluid supply path and vigorously flows into the fluid pool to form a pool, and at the same time, it flows into the gap between the outer peripheral wall of the bearing portion and the inner peripheral wall of the revolving structure to form a film having a bearing function.

The pipe cleaning device is pressed against the inner wall of the pipe by the reaction force of the jet injected from the unbalanced force injection hole, and is smoothly guided by the guide portion in the turning direction to the inner peripheral wall of the pipe. Turn at a fast speed along. At this time, in the case of the embodiment in which the end portion of the guide portion is formed in a blade shape, the adhered matter strongly adhered to the inner wall of the pipe is efficiently removed. Further, the self-propelled injection hole and the unbalanced force injection hole remove and deposit the deposits in the pipe.
