Description

Sewer pipe cleaning device {Sewer pipe cleaning device}

The present invention relates to a sewage pipe cleaning device that cleans sludge and clears clogged parts of sewage pipes, and more particularly, cleans the sludge accumulated in the sewer pipes while rotating it while inserting a wire into the sewer pipe. It relates to a sewage pipe cleaning device that can be easily performed by a single operator.

In general, the sewage pipe is a small sewage pipe connected to a home or building is connected to a main sewer pipe buried under a road, and the sewage used at home flows through the small sewer pipe to the river through the main sewer pipe.

In this way, the small sewer pipe connected to the main sewer pipe is formed with a small diameter, so various dirt and sludge are accumulated inside the sewer pipe and decayed, causing odor and clogging the sewer pipe.

Conventionally, in order to pierce the clogged sewer pipe, compression by a piston was used, but this is not only cumbersome but also requires a lot of force, resulting in poor workability because it uses human power and compresses the inlet of the sewer pipe. There was a problem.

In order to solve this problem, a "sewer pipe cleaner" as in Registered Utility Model No. 20-0286381 has been disclosed. It is drawn out through a discharge hole formed vertically in the front, and the wire is formed by inserting a wire wire having a spiral head coupled to the tip inside the synthetic resin pipe, and a rotation handle is coupled to rotate the wire wire at the rear of the storage box.

It moves to the position of the clogged sewer pipe, releases the wire from the drum, continuously inserts the spiral head at the tip of the wire wire into the clogged sewer pipe, and rotates the rotary handle at the rear of the container to rotate the wire wire, so that the spiral head rotates to prevent clogging. It cleans foreign substances in the sewer pipe with little force, so it is easy to drill.

However, in the conventional device described above, it is difficult for one person to work because the operation of continuously inserting the spiral head of the tip of the wire wire into the clogged sewage pipe and the operation of rotating the wire wire by rotating the rotation knob at the rear of the storage box must be performed at the same time. Since they have to work together, there is a problem of poor economics and workability.

Of course, an electric motor may be installed instead of the rotary handle so that the wire wire connected to the motor shaft of the electric motor can be rotated more simply by electric power. It still had the problem of being difficult to work with at the same time.

In addition, in the conventional device, since the wire is vertically discharged from the front of the container to the vertical discharge port, when the wire is pulled out in an inclined direction instead of forward, the wire retracting operation is hindered by frictional resistance on the vertical discharge port. there was

In addition, the motor shaft of the electric motor is connected to the wire of the wire, and the electric motor must be coupled to the rotational axis of the drum in a straight position to connect the power line, so the device is bulky and the appearance of the product is reduced. there was also

Next, let's take a look at the operation and action of the present invention configured as above.

First, the sewage pipe cleaning and blockage piercing device 100 of the present invention is moved to a work place where the sewage pipe 2 is blocked.

In this state, the foot switch 50 is placed adjacent to the clogged sewage pipe 2.

In addition, the flexible tubular body 23 wound around the rotating drum 20 in the cylindrical body 10 is pulled out together with the rotating wire 22 and moved to the position of the clogged sewage pipe 2.

That is, the rotating drum 20 inside the cylindrical body 10 rotates around the rotating shaft 12 by pulling the flexible tube body 23 to the outside through the outlet 32 formed in the upper cover 30. While doing so, the flexible tubular body 23 and the rotating wire 22 wound around the outer periphery of the rotating drum are unwound together and drawn to the outside, thereby moving them to the location of the clogged sewer pipe 2.

At this time, the outlet 32 of the upper cover has an upward slope in a tubular shape, so that the flexible body 23 is pulled out more naturally without additional resistance from the outlet 32 due to an external force pulling the flexible body 23.

In this way, after the flexible tube body 23 is withdrawn to an appropriate length, the fixing bolt 33 of the outlet 32 is tightened to pressurize the flexible tube body 23 so that it does not appear or come out anymore.

On the other hand, in the process of withdrawing the flexible body 23 by the rotation of the rotating drum 20, the motor shaft 42 of the electric motor 40 is connected to the rear end of the rotating wire 22, so that the rotating drum 20 Along with that, the electric motor 40 also rotates.

At this time, the coupler 43 and the flexible pipe body 23 connected to the motor shaft 42 of the electric motor 40 may be directly connected, but rotated by the connectors 44 and 45 as shown in FIG. 7 Since the drum 20 is connected to a separate jarrabar tube body 24 and the jarra bar tube body 24 is naturally bent and installed inside the rotary drum, it rotates more naturally together with the rotary drum 20.

In addition, when the electric motor 40 is rotated by the rotary drum 20, the electric motor 40 and the foot switch 50 are continuously connected to the ground through the power line.

This is coupled to the rotary drum 20 at the center of the bottom in a ring shape and connected to the power line connected to the electric motor 40. Even if the fixed contact part 65 connected to the power line connected to the foot switch 50 is grounded and the rotating contact part 60 rotates together when the rotary drum rotates, the fixed contact part 65 Since the ground state is continuously maintained, the foot switch 50 and the electric motor 40 are electrically connected to continue to be maintained.

In this way, in the state in which the work is ready, one worker places the operation head 21 at the tip of the rotating wire 22 inserted into the flexible pipe body 23 into the clogged drain 2 at the cleaning position and clogging position of the sewer. insert up to

At the same time, when one worker presses and manipulates the footrest 51 of the foot switch 50 using his foot, the motor shaft 42 of the electric motor 40 electrically connected to the foot switch rotates while flexi The rotating wire 22 inside the pipe body rotates, and the operating head 21 at the tip of the rotating wire rotates and expands outward to clean the sludge accumulated inside the sewer pipe and to pierce the clogged part inside the sewer pipe.

That is, a single worker rotates the rotary wire 22 by operating the foot switch 50 with his foot while inserting the operating head 21 of the tip of the rotary wire into the clogged sewer 2 with his hand and piled up in the sewer pipe. Since it cleans the sludge and unclogs the clogged part, it is possible for one worker to clean the sludge and unclog the sewer by himself.

In particular, by pressing and adjusting the footrest 51 of the footrest switch 50, the rotational speed of the rotating wire 22 by the electric motor 40 can be increased or decreased to more effectively pierce the clogged part of the sewer. .

After such use, the foot switch 50 is separately carried, and the flexible body 23 and the rotating wire 22 are re-wound around the rotary drum 20 and carried.

In addition, the battery of the foot switch 50 can be recharged after use and used.

Therefore, the present invention draws out the rotating wire 22 wound around the rotating drum 20 together with the flexible tube body 23 from the cylindrical body 10 and inserts it into the clogged sewer pipe, and the power transmission by manipulating the foot switch 50 By controlling the operation of the motor, the rotating wire is rotated to clean the sludge accumulated in the sewer pipe and to clear the clogged drain, so it is easy to work by one worker.
