Therefore, when the inclined protrusion 42 is installed, it is preferable to arrange the inclined portion so as to face the direction in which the foreign matter 1 mixed in the upper and the sewage flows.

In addition, it is preferable that both ends of the inner tube body 40 is fixed to the protrusion 12 protruding inwardly from both ends of the outer tube body 10 through an adhesive means.

Subsequently, the air pump 50, the electronic control valve 60, the first and second pressure sensors 70 and 70 ', the control unit 80 and the flow checking device 80 will be described in sequence.

The air pump 50 is a known compressor, the power supply is received from the outside, the operation control is operated by the control signal of the control unit 80 to be described later.

In the case of the air pump 50 is provided with an air supply pipe 51 is connected to the air bag (30).

The air supply pipe 51 has an extension part 51a extending from an air discharge port (not shown) of the air pump 50, one end of which is connected at equal intervals along the longitudinal direction of the extension part 51a, and the other end of the external pipe body. It consists of branches 51b which penetrate through the 10 and are respectively connected to the plurality of airbags 30.

The first and second pressure sensors 70 and 70' are provided at both front and rear ends of the inner tube 40 to receive the hydraulic pressure applied to the inner front and rear ends of the inner tube 40. Measure

The control unit 80 receives the measured values from the first and second pressure sensors 70 and 70 ', respectively, and compares the measured values with each other, but the measured values between the two pressure sensors 70 and 70' differ by more than the set value. If this occurs, the air pump 50 and the electronic control valve 60 to control the operation to remove the foreign matter (1).

In more detail, when the foreign matter (1) mixed in the water and sewage along the inner tube (40) is gradually deposited by the deposition of the foreign matter (1) in the process of moving to block some sections of the pipe water and sewage Is no longer flowing, and the first and second pressure sensors 70 and 70 'installed at both ends of the inner tube 40 are respectively sensed (measured), and the detected signal (measured value) is controlled by the control unit. And a value measured by each of the first pressure sensor 70 and the second pressure sensor 70 'exceeds a predetermined reference value (pressure difference between the first pressure sensor and the second pressure sensor). In this case, the control unit 80 is to control the operation of the air pump 50 and the electronic control valve 60, as mentioned above.

In the present embodiment, each of the first and second pressure sensors 70 and 70 'is installed in each of the outer pipes 10, but this is only one embodiment. For example, the inside of one outer pipe 10 is provided. Since the first pressure sensor 70 may be installed at the front end and the second pressure sensor 70 'may be installed at the inner end of the other outer tube 10, the present invention may not be limited thereto. not.

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

As shown in FIG. 6A, when the upper and the sewage flow into the inner tube 40 while the foreign substance 1 is accumulated inside the inner tube 40, the fluid resistance is caused by the foreign substance 1 to the upper and lower sewage. As a result, the pressure of the front end portion (inflow portion) of the inner tube body 40 becomes higher than that of the rear end portion (flow portion).

In addition, since the pressure difference between the front and rear ends of the inner tube 40 increases as the amount of the foreign matter 1 increases, the inner tube 40 is measured by measuring the pressure difference between the front and rear ends of the inner tube 40. The amount of foreign matter (1) accumulated in the interior can be measured indirectly.

Therefore, when the pressure difference between the front and rear ends of the inner tube 40 measured by the first and second pressure sensors 70 and 70 'becomes larger than the preset pressure difference, the control unit 80 is internal By determining that a large amount of foreign matter 1 is accumulated in the pipe body 40, the air pump 50 and the electronic control valve 60 are controlled to supply high pressure air to each air bag 30.

In this case, as shown in FIG. 6B, the control unit 80 first opens the electronic control valve 60 at the front (a portion into which the upper and lower water flows) so that high pressure air is supplied to the front air bag 30. Afterwards, the high-pressure air is supplied to the airbag 30 at the rear side (the portion where the upper and lower water flows out).

In addition, the control unit 80 closes the electronic control valve 60 so that no more air is supplied to the airbag 30 when the set time elapses after the electronic control valve 60 is opened, and the airbag 30 Since the air supplied into the inside is discharged into the inner tube 40 through the air holes (31, 41), the air bag 30 is gradually reduced to return to its original size.

As such, when air is sequentially supplied and inflated from the front airbag 30 to the rear airbag 30, the airbag 30 presses the circumferential surface of the inner tube 40 in order from the front to the rear to the inner tube. By narrowing the inner diameter of the 40, the foreign matter 1 accumulated in the inner tube body 40 is pushed out and discharged backward.

This action is similar to inserting the inside of the sundae into the entrance of the sundae and filling the inside of the sundae and pushing the circumference of the sundae by hand and pushing it backward so that the contents are pushed backward.

At this time, the high-pressure air supplied into the air bag 30 is introduced into the inner tube 40 through the air holes 31 and 41 so that the foreign matter 1 accumulated in the inner tube 40 is accumulated. By floating upward, the foreign matter 1 is discharged to the rear more effectively.

In addition, the foreign matter 1 is caught by the inclined protrusion 21 and is pushed back only without backward flow.

Therefore, when the foreign body 1 is accumulated inside the pipe body A, in particular, the inner pipe body 40 in a state in which the pipe body A is configured to connect to the pipe body A, in particular, the inner pipe body 40, the control unit 80 By detecting this and controlling the air pump 50 and the electronic control valve 60 to be inflated sequentially from the front air bag 30 to the rear air bag 30, foreign matter accumulated in the inner tube 40 (1) is pushed backwards and discharged, and this process can be repeated to completely discharge the foreign matter (1).

The water and sewage pipe connecting structure configured as described above sequentially supplies air to the plurality of airbags 30 coupled to the outside of the inner tube 40, and pushes the foreign substances 1 accumulated in the inner tube 40 to the rear side. By taking out and discharging, there is an advantage that can prevent the foreign matter (1) accumulated in the interior of the water and sewage pipe line to be blocked.

In addition, the flanges 11 of the adjacent outer tube 10 can be interconnected via the tube connector 20, so that the separation and separation of the outer tube 10 can be greatly improved. have.

In addition, the control unit 80 measures the pressure difference between the inner and rear ends of the inner tube 40 by using the first and second pressure sensors 70 and 70 ′ provided at both front and rear ends of the inner tube 40. Indirectly by measuring the amount of the foreign matter (1) accumulated in the inner tube (40) automatically removes the foreign matter (1) inside the inner tube (40), effectively removing the foreign matter (1) before a lot of foreign matter (1) There is an advantage to this.

In addition, the airbags 30 and the inner tube 40 have air holes 31 and 41 communicating with each other, and the high-pressure air supplied into the airbags 30 is provided through the air holes 31 and 41. Since the foreign matter 1 that flows into the inner tube 40 and accumulated in the inner tube 40 rises upward, the foreign substance 1 may be discharged to the rear more effectively.

It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the present invention as defined by the appended claims.
