The present invention relates to a device for cleaning the inside of a pipe using a fan brush. More specifically, the fan brush is rotated by a strong air pressure and a hydraulic pressure, and at the same time, the foreign substances on the inner surface of the pipe are removed neatly by a rotating cap that rotates. It is to be done.

In general, sewage pipes scattered with various wastes and debris, and chimneys of factories that are dusty with soot had to be regularly located for smooth communication. If the inside of the pipe is not regularly located, the pipe is clogged by foreign matter and dirt flows back out, and if the foreign matter is stuck inside the pipe for a long time, the corrosion of the pipe has occurred. If not, the operator directly cleans the inside of the pipe by using the equipment, but if the inside of the pipe is deep and curved, the high pressure hose is pushed into the inside of the pipe, and a strong water pressure is supplied to prevent soil, dirt or dust inside the pipe. It can be removed by the injection force of.

However, the above-described prior art cannot clean the foreign matter adhered to the inner surface of the tube without cleaning for a long time, no matter how strong the hydraulic pressure is sprayed, and also the force of the hydraulic pressure becomes relatively weak when the tube is bent and the uneven part is relatively weak. Only a large amount of water was consumed, there was a problem that can not clean the inner surface of the tube. Furthermore, a method based on air pressure is also used, but this also does not solve the above problems of the prior art.

The present invention has been proposed in order to solve the problems of the prior art as described above, the inside of the tube using a fan brush to remove the foreign matter on the inner surface of the tube by rotating the fan brush by the strong air pressure and hydraulic pressure injection force The purpose is to provide a device.

When described in detail according to the accompanying drawings of the present invention for the achievement of the neck as follows.

As shown in FIGS. 1 and 2, a second bearing 13 is inserted into the guide groove 12 in one housing 11 of the flexible tube 9 having the threaded portion 10, thereby providing a strong air pressure. A fan brush 1 coupled to the second bearing 13 to be rotated smoothly by the discharge of water pressure, and a collecting portion 19 and a tip portion that allow the air pressure and the water pressure to vortex in a conical shape. At the same time, a plurality of ejection holes 15 are laid and the rotating cap 14 is provided with a shaft 18 at the center thereof, and the other end thereof is guided so that the other end can be coupled to one side of the fan brush 1. It consists of the blowoff pipe 20 provided with the housing 11a in which the bearing 13 was inserted in the groove 12a. In addition, the fan brush 1 is installed at a predetermined position of the shaft 18, the first bearing 8 and the first fan 2 is installed so that it can be rotated smoothly by the pressure of the air pressure and water pressure, the circular body (3) On the outer circumferential surface, a plurality of fastening holes 7 are laid so that the fastening bolt 4 formed with the + magnetic groove 6 and the brush 5 is fastened. In addition, the rotation cap 14 is provided with a third bearing 17 and the first fan 16 is installed at a predetermined position of the shaft 18 so that it can be rotated smoothly by the pressure of the air pressure and the hydraulic pressure. Reference numeral 23 is a suction line.

Referring to the effects of the present invention configured as described above are as follows.

3 (a) and 3 (b) show an exemplary view of cleaning the sewage pipe 21 and the like, and (c) is an exemplary view of cleaning the chimney 21a. As shown in FIG. 3 (a), first, the hose 22 is connected to the threaded portion 10 of the flexible pipe 9, and then the air pressure and the hydraulic pressure are strongly discharged from the supply part not shown. A plurality of fan brushes 1 are introduced into the sewer pipe 21 while rotating. At this time, the flexible tube 9 and the inner shaft 18 is formed of a flexible material to facilitate the operation in the curved tube 21.

On both sides of the fan brush (1) is to allow a plurality of housings (11, 11a) formed with guide grooves (12, 12a) and a plurality of flexible pipes (9) connected to each other, the guide grooves (12, 12a) The fan brush 1 is provided with first and second bearings 8 and 13, and the fan brush 1 is provided with a first fan 2 so that the fan brush 1 is discharged by air pressure and water pressure. ) Can be rotated smoothly.

A fastening bolt 4 having a plurality of brushes 5 formed therein is installed on the outer circumferential surface of the body 3 of the fan brush 1 that is rotated in this way so that the foreign substance A attached to the inner surface of the pipe 21 is brushed 5. It can be removed by the rotation of the. At this time, when the brush 5 of the fastening bolt 4 is worn out for a long time, loosen the fastening bolt 4 by using a tool such as a screwdriver in the + self-groove 6 and replace it with a new one. It can be fastened to.

The air pressure and the water pressure transferred while rotating the plurality of fan brushes 1 are collected 19 of the shaft 18 while rotating the rotary cap 14 provided with the third bearing 17 and the second fan 16. By no longer moving forward by the rotation of the rotary cap 14 to obtain a propulsion force through the inclined blowout hole 15 at a predetermined angle to be able to eject the air pressure and water pressure in the vortex type.

When the inner surface of the tube 21 is cleaned in the above manner, and the hose 22 is pulled out by a driving force (not shown), the plurality of fan brushes 1 as shown in FIG. The flexible tube 9 is fastened to the outside thus drawn out.

At this time, the rotating cap 14 is drawn out of the foreign matter (A) remaining in the inside of the tube 21 by the air pressure and water pressure ejected to the rear while the plurality of fan brushes (1) is rotated and such foreign matter (A) is Inhaled by the suction pipe (23) is gathered in a place not shown.

The present invention is to be used to supply only the air pressure when cleaning the chimney pipe (21a) and to use the air pressure and water pressure or, if necessary, at the same time when cleaning the sewage pipe (21).

As described above, the present invention is to eject a strong air pressure and water pressure to rotate a plurality of fan brushes and at the same time to vortex by the rotation cap to rotate the air pressure and water pressure to remove the foreign matter on the inner surface of the tube, It is a very useful invention that can reduce the working time and improve the work efficiency.
