Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tool for cleaning a drain pipe for draining rainwater. 2. Description of the Related Art Generally, drain pipes for draining rainwater are buried on the floor of a building or on a veranda. The inflow port of this drain pipe has various shapes such as a rain gutter inserted therein and a structure in which a dust cover having a number of slits is attached. However, the drainage pipes are installed in a narrow space between the floor of the upper floor of the building and the ceiling of the lower floor, so that the inlet is vertical, Is bent laterally to form an L shape. For this reason, on a veranda with a small flow of rainwater,
Even if a dust cover is attached to the inflow port, there is a problem that fine dust collects in the L-shaped portion of the drain pipe and the drain pipe is clogged. When the drain pipe is clogged and cannot be drained in this way, a specialized repair contractor is called for cleaning. In this method, high-pressure water is injected into the clogged drainage pipe to remove debris that has clogged up inside.However, this operation requires a large pump truck and requires a lot of manpower, so repair costs are high. There was a high problem. SUMMARY OF THE INVENTION [0004] The present invention is to provide a drain pipe cleaning tool which eliminates the above-mentioned drawbacks and which can easily remove clogged drain pipe dust with an extremely simple device. is there. [0005] The drain cleaning tool according to the first aspect of the present invention According to an aspect of the flexible tube distally,
Removably attaches by penetrating the center of cylindrical sponge
A disc-shaped holding plate made of an elastic material and having a smaller outer diameter than this sponge is detachably attached to the flexible tube.
In addition , the sponge is sandwiched and fixed from both sides, and a connection portion of a water hose is formed on a rear end side of the flexible tube. [0006] How to use the drain cleaning tool of the effects of the present invention, first connect the water supply hose to the connection portion of the drain cleaning tool, off
While spraying water from the tip of the flexible tube, the drain pipe cleaning tool is pushed into the drain pipe while moving it back and forth from the inlet. Since the outer diameter of the sponge is formed to be slightly larger than the inner diameter of the drain pipe, the sponge is compressed and comes into close contact with the inner wall of the drain pipe. In this way, the sponge rubs the inner wall of the drainage pipe with a sponge while spraying water to drop off and remove the attached dust. Further, the flexible tube bends freely along the shape of the drainage pipe and reaches the inside of the drainage pipe. Similarly, the inner wall is rubbed with a sponge while pushing the accumulated dust with the pressing plate at the tip, thereby forming a muddy state. Rinsed trash can be washed away with water and cleaned. Drain pipe cleaning tools are disassembled and assembled.
Since it has a structure, if the sponge and the holding plate are replaced according to the inner diameter of the drain pipe to be cleaned, cleaning can be performed under optimum conditions. An embodiment of the present invention will be described below in detail with reference to FIGS. In the drawing, reference numeral 1 denotes a drainage pipe cleaning tool, which penetrates the distal end side of a bellows-shaped flexible flexible tube 2 through the center of two cylindrical sponges 3, 3, and from both sides of the sponges 3, 3. It is sandwiched and fixed between disc-shaped pressing plates 4 and 4 formed of an elastic body such as a rubber plate. As shown in FIG. 2, a disc-shaped pressing plate 4 made of an elastic body is also mounted between the sponges 3 and 3. The outer diameter of the cylindrical sponge 3 is slightly larger than the inner diameter of the drain pipe 5 to be cleaned, and the outer diameter of the disc-shaped holding plate 4 is formed to be slightly smaller than the inner diameter of the drain pipe 5. [0009] Further, holding plates 4 provided on both sides of the sponge 3,
The fixing structure of 4 is a flexible flexible tube 2
At the tip side of and slightly above this, stop bolts 7, 7 are penetrated in the lateral direction and are detachably attached. Stopper rings 8, 8 are attached to the side of the stop bolts 7, 7,
Pressing plates 4, 4 are supported beside the stopper rings 8, 8, and sponges 3, 3 are held between the pressing plates 4, 4. Therefore, the assembling method is to fix the upper fixing bolt 7 by penetrating the flexible flexible tube 2 in the lateral direction and then from the distal end side of the flexible flexible tube 2 to the stopper ring 8, the disc-shaped holding plate 4, The cylindrical sponge 3, the holding plate 4, the sponge 3, the holding plate 4, and the stopper ring 8 are inserted in this order, and finally, the stop bolt 7 on the tip side is inserted into the flexible flexible tube 2.
In this case, the cylindrical sponges 3 are clamped from both sides by the holding plates 4 and fixed. Flexible tube 2
A connection portion 10 of a water hose 9 provided with an annular concave and convex portion is attached to an upper end side of the water hose. Next, a case where the drain pipe 5 is cleaned by the drain pipe cleaning tool 1 having the above structure will be described. First, a dust cover (not shown) attached to the inflow port 6 of the drain pipe 5 is removed, and a water hose 9 is connected to the connection portion 10 of the drain pipe cleaning tool 1.
And water 11 is sprayed from the tip of the flexible tube 2. In this way, as shown in FIG. 3, the drain pipe cleaning tool 1 is inserted into the drain pipe 5 from the inflow port 6. In this case, since the outer diameter of the sponge 3 is formed slightly larger than the inner diameter of the drain pipe 5, the sponge 3 is pressed and shrunk and comes into close contact with the inner wall of the drain pipe 5. In this way, while spouting the water 11, the inner wall of the drain pipe 5 is rubbed with the sponge 3, and the attached dust 12 is dropped and washed away. Further, when the drain pipe cleaning tool 1 is pushed in while being moved back and forth, the flexible flexible tube 2 bends freely along the shape of the drain pipe 5 as shown in FIG. Reach Similarly, the water 11 is supplied to the accumulated dust 12, and the inner wall is rubbed with the sponge 3 while being pressed by the pressing plate 4 at the tip, and the mud-like dust 12 is washed away with the water 11 and cleaned. be able to. Accordingly, since the sponge 3 supported by the holding plate 4 rubs the inner wall of the drain pipe 5 and forcibly removes the dust 12 in a muddy state, the water pressure is sufficient with tap water, and a large pump is required. Not easy to clean. The drain pipe cleaning tool 1 has a structure in which the sponge 3 and the holding plate 4 are detachably attached to the flexible tube 2 so that it can be easily disassembled and assembled. If the sponge 3 and the holding plate 4 having different outer diameters are replaced with each other, cleaning can be performed efficiently under optimum conditions. As described above, according to the drain pipe cleaning tool of the present invention, it is possible to easily remove the clogged dust from the drain pipe by connecting it to a water hose with an extremely simple device. Can be. Further, since the drain pipe cleaning tool has a disassembled and assembled structure , if the sponge and the holding plate are replaced according to the inner diameter of the drain pipe to be cleaned, cleaning can be performed under optimum conditions. Further formed with flexible tubing
Since it is bent, it can be freely bent along the shape of the drain pipe and inserted into the drain pipe, and the dust accumulated on the horizontal portion can be washed away with water and cleaned.
