The brush 3 is preferably flocked perpendicularly to the surface of the central shaft 2 and is implanted to circular arc shape in section.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cleaning tool for cleaning the inside of a pipe, and more particularly to a pipe cleaning tool using dry air and compressed air.

[0002]

2. Description of the Related Art Conventionally, when cleaning the inside of a detachable pipe, cleaning using a brush with a long handle or cleaning using high-pressure water has been performed, but such work is troublesome. In addition, there is a problem that a large amount of time is required for drying in the case of washing. In addition, a method has been adopted in which the inside of the pipe is cleaned by passing the inside of the pipe with compressed air using a scourer-like cleaning tool having a large number of brushes implanted on the surface.

[0003]

However, in this case, the contact between the inside of the pipe and one of the bristles of the brush becomes a point, and the corresponding contact becomes a straight line due to the transfer of the brush by the compressed air, and the adhered matter inside the pipe, etc. Is difficult to remove and clean without fail, and there is a problem that the transfer is easily hindered by deposits inside the piping.

SUMMARY OF THE INVENTION [0004] In view of the above, an object of the present invention is to provide a pipe cleaning tool that reliably removes and cleans deposits and the like inside a pipe and smoothly moves inside the pipe.

[0005]

A first aspect of the present invention for achieving the above object comprises a central shaft and a cleaning unit having a brush implanted on the surface of the central shaft, wherein the central shaft is a hollow cylinder. A screw rotor is fixedly provided inside the central shaft.

In the present invention having the above-described structure, the cleaning tool cleans the inside of the pipe with a brush and moves while rotating with compressed air.

A second aspect of the present invention is characterized in that the rotating shaft comprises a central shaft and a cleaning unit having a brush implanted on the surface of the central shaft, and a rotating blade for rotating the central shaft is provided on the end surface of the central shaft. And

In the present invention having the above structure, the rotating blades are provided on the end face of the central shaft, so that the rotating blades can be made large, and thus the rotation efficiency is improved.

According to a third aspect of the present invention, the brush of the cleaning section is
It is characterized in that the flocking at the central portion in the longitudinal direction is slightly longer than the flocking at the end face and is planted in an arc shape.

In the present invention having the above-described structure, the brush implantation length of the cleaning section is made longer at the central portion than at the end face, so that the movement in the pipe is smooth and does not hinder.

According to a fourth aspect of the present invention, in the second aspect of the present invention, the rotary blade is attached so as to adjust the torsion angle.

According to the present invention having the above structure, the ratio between the rotational force and the propulsive force of the pipe cleaning tool can be changed.

[0013]

1 to 3 show a first embodiment of a pipe cleaning tool according to the present invention. The pipe cleaning tool 1 has a central axis 2 of a hollow cylinder and is implanted on the surface of the central axis 2. A screw-shaped rotor 4 is inserted into the brush 3 and the center shaft 2. The outer diameter of the rotor 4 is substantially the same as the inner diameter of the center shaft 2,
Insert by press fitting. In order to transmit the rotational force of the rotor 4 to the central shaft 2 properly, it is bonded and fixed by bonding means such as welding at several connecting points 5. In the figure, reference numeral 6 denotes a screw shaft.

The brush 3 is made of the same material as a so-called scourer or the like used at home or a wire used for a metal brush or the like. The brush 3 is implanted at right angles to the surface of the central shaft 2 and is arranged in an arcuate cross-sectional shape that is longer as it approaches the central planted 3b than the length of the implanted hair 3a at both end surfaces of the central shaft 2. Is preferred.

In the above construction, when cleaning the pipe, a pipe cleaning tool 1 adapted to the inner diameter of the pipe W is inserted into the end face of the pipe W removed as shown in FIG. 2, and the compressed air jet bracket 21 is attached to the end face. It is fixed by bolts 22 using the mounting holes of the piping. Various brackets 21 are prepared according to the type of piping.

The bracket 21 is connected to an accumulator A for storing compressed air, and blows out compressed air sent from the accumulator A into the piping. In FIG. 3, the compressed air A1 jetted from the bracket 21 hits the surface 4a of the rotor 4 to generate a rotational force X and a propulsive force Y. The pipe cleaning tool 1 is rotated by the rotational force X, and at the same time, the inside of the pipe is pushed by the air pressure to move.

The outer diameter of the center shaft 2 is determined according to the inner diameter of the pipe to be cleaned. If the pipe has a relatively small diameter, the screw-shaped rotor 4 to be inserted into the center shaft 2 is used. In such a case, the pipe cleaning tool 10 of the second embodiment is used.

FIG. 4 shows a second embodiment of the present invention. A pipe cleaning tool 10 has a brush 12 made of a large number of flocks, which is planted on the surface of a small-diameter central shaft 11 in the same manner as the pipe cleaning tool 1. As in the case of the cleaning tool 1, the cross section has a middle and high arc shape.
A rotating blade 13 such as a swirling fan is fixed to one end face of the center shaft 11. The rotating blade 13 has its central portion 16 fixed to the central shaft 11 by a fixing means such as welding, and transmits the rotating motion of the rotating blade 13 to the central shaft 11. The rotating blade 13 has a plurality of blades 14a, 14b, 14c, 14d.
.. (Hereinafter collectively referred to as blades 14) (four blades in the example in the figure), each of which has a blade shaft 15a, 15b, 15
c, 15d (hereinafter collectively referred to as blade shaft 15)
Is fixed to the center portion 16 by a set screw 17 so as to be rotatable around the blade shaft 15.

The outer diameter of the rotary blade 13 is smaller than the outer diameter of the brush 12 on the end face of the central shaft 11 in order to avoid interference with the inside of the pipe. The pipe cleaning tool 10 can be used not only when the inside diameter of the pipe is small, but also when the inside diameter is relatively large.

In FIG. 3, the ratio of the rotational force X to the propulsive force Y changes depending on the screw arrangement angle α of the rotor 4. The same applies to the twist angle of the rotating blade of the pipe cleaning tool 10 of the second embodiment. FIG. 6 shows a twist angle adjustment procedure, and shows an example in which the twist angle of the rotating blade of the pipe cleaning tool 10 can be adjusted. That is, by rotating the blade shaft 15 at an appropriate angle and fixing it with the set screw 17,
The rotary blade 14 is adjusted and held at a required angle β. Accordingly, in the case of the pipe cleaning tool 10, the ratio between the rotational force X and the propulsion force Y can be appropriately changed according to the contamination in the pipe.

[0021]

As described above, according to the present invention, the rotating blades are attached to the cleaning section in which the brush is implanted, and the pipe cleaning tool is not only moved in the pipe by compressed air but also moved with rotation. As a result, dirt in the pipe is reliably removed, and the transfer is not hindered. Also,
When the brush to be implanted on the surface of the central shaft is implanted in an arc-shaped cross section, the transition in the pipe becomes smooth. Further, when the twist angle of the rotating blade can be freely adjusted, it is easy to appropriately change the rotational force and the propulsive force of the pipe cleaning tool according to the contamination of the pipe, and the cleaning method is to use compressed air. Since it is used, there is an effect that drying after cleaning is unnecessary.
