The connecting unit is air-tightly connected to the wall, so that the water sprayed back during the dredging process can be prevented from splashing to the outside.

Description

How to unclog drain pipes

The present invention relates to a drainage pipeline, in particular to a method for dredging the drainage pipeline.

Generally, when the drainage pipe is blocked by foreign objects and needs to be dredged, a water pipe is usually inserted into the drainage pipe and flushed with a high-pressure water column.

However, when the high-pressure water column is used to unclog the drainage pipe, although the water column is pressurized, since a lot of water has accumulated in the drainage pipe, the pressurized water column will reduce the impact force after contacting the accumulated water, so it will be blocked when the water column is blocked. When the position is deep or the foreign matter adheres to the pipe wall of the drainage pipe, the high-pressure water column cannot effectively displace the foreign matter, so the drainage pipe cannot be effectively dredged.

In addition, in the process of dredging the drainage pipeline, the accumulated water is often affected by the impact force of the high-pressure water column, causing the pressure to increase and spray back to the drainage outlet, which not only affects the dredging operation, but also causes the accumulated water to splash to The surface around the drain is dirty and needs to be improved.

Therefore, it is an object of the present invention to provide a method for dredging a drain which overcomes at least one of the disadvantages of the prior art.

Therefore, the method for dredging a drainage pipe of the present invention is suitable for passing the pressurized water and air to unclog a drainage pipe arranged on a wall. The method for dredging the drainage pipeline includes the following steps 1 and 2.

Step 1: Corresponding a body unit of a drainage pipe dredging device to the drainage pipe, and air-tightly butting a connecting unit of the drainage pipe dredging device to the wall body.

Step 2: Input the pressurized water and air through the end of the body unit relatively far from the drainage pipe and enter the drainage pipe through the body unit to dredge the drainage pipe.

The effect of the present invention is: by air-tightly connecting the connecting unit to the wall, the water sprayed back during the dredging process can be prevented from splashing to the outside of the drainage pipe dredging device, and the pressurized water and The air is input into the drainage pipe through the body unit. Since the air molecules are small, it can help to pass through the gap between several foreign objects in the water, so it can effectively promote the relative displacement of the foreign objects to dredge the drainage pipe.

Referring to FIG. 6 to FIG. 8 , a second embodiment of the method for dredging a drainage pipe of the present invention is similar to the first embodiment, and the differences are:

The wall 11 also has a surrounding surface 113 surrounding one end of the drainage pipe 12 adjacent to the drainage port 121 .

Referring to FIGS. 7 to 10 , in step 1, the base member 21 of the main body unit 2 has an insertion section 214 suitable for being inserted into the drainage pipe 12 and whose outer diameter is smaller than the hole diameter of the drainage pipe 12 . The exposed section 215 outside the wall body 11 and a dredging section 216 connected to the side of the insertion section 214 opposite to the exposed section 215 .

The drainage inlets 221 of the drainage chamber 22 are disposed in the exposed section 215 , and the drainage outlet 222 is formed in the dredging section 216 .

The air pressure chamber 23 of the body unit 2 has a first air port 233 formed in the exposed section 215 and a second air port 234 formed in the insertion section 214 .

The connecting unit 3 includes a set of connecting pieces 34 arranged on the insertion section 214 of the base piece 21 , and two connecting pieces 34 respectively connected to opposite ends of the connecting piece 34 and extending the connecting pieces 34 along the extending direction of the base piece 21 . The collar 35 is positioned relative to the insertion section 214 . A chamber 36 having a variable volume and communicating with the second air port 234 is formed between the connecting member 34 and the inserting section 214 of the base member 21 . In this embodiment, the collar 35 located above the connecting piece 34 is fixed to the base piece 21 , and the collar 35 located below the connecting piece 34 is screwed to the base piece 21 .

In the drainage pipe dredging device, the base member 21 is partially inserted into the drainage pipe 12 and gas is supplied to the first air port 233 to increase the volume of the chamber 36, so that the connecting member 34 is forced against the surrounding surface 113, It is airtightly connected with the surrounding portion 112 of the wall body 11 (see the first figure from the left of FIG. 10 ).

After completing the dredging operation of the drainage pipe 12 according to the first step and the second step, the first air port 233 is pumped to reduce the volume of the chamber 36, so that the connecting piece 34 is no longer pressed against the surrounding surface. 113 (see the first picture from the right in FIG. 10 ), and then the base member 21 can be taken out from the drainage pipe 12 .

It is worth mentioning that, in the present embodiment, the outer surface of the connecting member 34 is formed with four spaced apart and annular protruding ribs 341 around the inserting section 214 . When the connecting member 34 presses against the surrounding surface 113 , the protruding ribs 341 can form a multi-stage air-tight connection with the surrounding surface 113 to achieve a better water blocking effect. For example, in FIG. 8 , the two protruding ribs 341 are pressed against the surrounding surface 113. When the water is sprayed back, the two protruding ribs 341 pressing against the surrounding surface 113 can provide a two-stage blocking effect, that is to say, when the pressure in the drainage pipe 12 is too high, the water sprayed back When the pressure is too large to rush through between the lower rib 341 and the surrounding surface 113 , the upper rib 341 can further block and prevent the water from rushing up further.

In this way, the second embodiment can also achieve the same purpose and effect as the first embodiment.

To sum up, in the method for dredging a drainage pipe of the present invention, by air-tightly connecting the connecting unit 3 of the drainage pipe dredging device to the wall body 11, it is possible to prevent the water sprayed back during the dredging process from splashing on the drainage. The pipe unblocks the outside of the device, and by feeding the pressurized water and air into the drainage pipe 12 through the body unit 2 of the drainage pipe unblocking device, since the molecules of the air are small, it can help to pass several foreign objects in the water. Therefore, the relative displacement of the foreign objects can be effectively pushed to dredge the drainage pipe 12, so the purpose of the present invention can be achieved.
