Referring to FIG. 1, the present invention is a drainage device that drains water to a drainage reservoir 20 lower than the reservoir 10 through a highest point T higher than the reservoir 10 using potential energy.

Potential energy applied to the present invention serves to push up the rear fluid in the direction in which the fluid is lowered by increasing the degree of vacuum further to the rear of the pipe when the fluid is stored in the pipe and then descends.

To this end, the reservoir 10 should be located at a higher position than the reservoir 20, and the potential energy therebetween uses a drop generated as it is changed into kinetic energy.

In order to generate the above-mentioned drop, a certain amount of water must be stored, and the drop and acceleration generated by lowering the water increase the degree of vacuum in the rear.

First, a certain amount of water must be stored to generate a drop. The water should be supplied from a reservoir 10 located at a relatively high position, and for this purpose, the present invention locates an inlet 32 under the water surface of the reservoir 10 and discharges the reservoir lower than the water level of the reservoir 10. Positioning the discharge port 34 in the 20, the pumping pipe 30 is installed to the suction port 32 and the discharge port 34 side, the non-return valve 36 and the fluid storage valve 38 is installed.

Pumping pipe 30 applied to the present invention is bisected at the highest point (T) located between the reservoir (10) and the reservoir (20).

The dividing pumping pipe 30 is provided with the aforementioned non-return valve 36 and the fluid storage valve 38, and the place where the drop is generated after storing the water of the reservoir 10 is the highest point (T). ), The water is filled from the fluid storage valve 38 to the same position as the water surface of the reservoir 10.

Pumping pipe diameter (mm) Amount of water discharged (ton / min) 100 1.8 200 7.2 300 16.2 500 44.9 1000 179.6

In selecting the size of the pumping pipe 30 applied to the present invention, for example, when a large amount of water to be drained per unit time for the purpose of flood prevention can be installed by applying a plurality of Ø1000mm or more, When the amount of water to be drained per unit time is small, such as in the case of using a wastewater treatment plant located near the drainage site for wastewater generated from a plant, etc., Ø100 mm or less may be applied.

Again, in order to store water for generating kinetic energy due to a drop in the pumping pipe 30 as described above, a vacuum pipe 40 is installed at intervals with the pumping pipe 30.

The vacuum pipe 40 is made of a relatively smaller diameter than the pumping pipe 30, one side is in communication with the pumping pipe 30 at a position higher than the fluid storage valve 38 installed in the pumping pipe (30). The first drain pipe 42 is provided, the other side is located below the water surface of the reservoir (10).

As above, the pumping pipe 30 is communicated by the first drain pipe 42 of the vacuum pipe 40 is supplied with the water of the reservoir 10, and, at the highest point of the pumping pipe 30, the vacuum pipe ( The connecting pipe 50 which is connected after being branched to 40 is installed.

The first drain pipe 42 and the connection pipe 50 serves as a passage for supplying water to the pumping pipe 30 in common.

In the present invention, various control valves are installed to supply water to the pumping pipe 30.

These control valves are provided with first, second, third, fourth and fifth shut-off valves 44, 46, 48, 52 and 90, and in particular, the first and third shut-off valves 44 and 48 on the vacuum pipe 40. Is provided, the fourth drain valve (52) is provided as the first drain pipe (42), and the second shutoff valve (46) is provided as the connecting pipe (50).

Preferably, the second shut-off valve 46 is to control the flow of water flowing between the pumping pipe 30 and the vacuum pipe 40 through the connecting pipe (50).

The drainage device having the above configuration must pump water to generate kinetic energy using a drop after supplying the water of the reservoir 10 to the pumping pipe 30 through the vacuum pipe 40.

To this end, in the vicinity of the vacuum pipe 40 and the first drain pipe 42 is connected to the vacuum pump 60 is installed to generate a vacuum pressure to the vacuum pipe 40 to suck the water of the reservoir (10) The water supply pipe 30 supplies water for generating a drop through the first drain pipe 42.

Next, the operation of the drainage device using the vacuum pressure according to the present invention provided with the above components and the effects thereof will be described in detail with reference to FIGS. 2, 3A, and 3B.

2 and 3a and 3b is an operating state diagram showing a process of filling the pumping water using the drainage device according to the present invention.

First, in order for the water of the reservoir 10 to be discharged continuously through the terrain higher than the reservoir 10 through the pumping pipe 30 to the drainage of the terrain lower than the reservoir, the water of the reservoir 10 pumping pipe 30 A preliminary procedure is required to fill water in the pumping pipe 30 from the non-return valve 36 installed to the fluid storage valve 38.

To this end, the non-return valve 36 and the fluid storage valve 38 installed in the pumping pipe 30 are temporarily closed.

Subsequently, the second shutoff valve 46 installed in the connecting pipe 50 is closed, and the first and third shutoff valves 44 and 48 on the vacuum pipe 40 and the fourth shutoff valve on the first drain pipe 42 are closed. Open 52.

This is for supplying water to the pumping pipe 30 through the first drain pipe 42.

After opening or closing the shut-off valves 44, 46, 48, 52 as described above to operate the vacuum pump 60 to generate a vacuum pressure in the vacuum pipe (40).

The generated vacuum pressure gradually reaches the reservoir 10 and begins to pump the water of the reservoir 10. The pumped water is filled with the pumping pipe 30 through the first drain pipe 42, and the water filled in the pumping pipe 30 is filled to the same position as the water surface of the reservoir 10.

In the present invention, the pumped water is filled up to the highest point T of the pumping pipe 30 to generate kinetic energy using the maximum drop.

To this end, as shown in FIG. 3A, the fourth shutoff valve 52 is closed and the second shutoff valve 46 on the connecting pipe 50 is opened to operate the vacuum pump 60.

In this case, as shown in FIG. 3B, the non-return valve 36 on the pumping pipe 30 may be selectively opened or closed. This does not significantly affect maintaining the vacuum force because the second shut-off valve 46 is open in generating the vacuum pressure.

Again, the vacuum pressure is increased by the operated vacuum pump 60, and optionally through the connecting pipe 50 of the pumping pipe 30 or the vacuum pipe 40, the check valve 36 is opened, After the water is pumped up to the highest point (T) of the pumping pipe (30).

If necessary, the water filled in the pumping pipe 30 in the present invention may be filled up to the non-return valve 36 and the fluid storage valve 38 of the pumping pipe (30).

As described above, the water filled in the pumping pipe 30 is concentrated inside the air at the highest point (T). In the present invention, the air vent 54 is installed in order to reliably generate a vacuum pressure and supply water smoothly, thereby discharging air in the pumping pipe 30.

When water is filled in the pumping pipe 30 as above, the second blocking valve 46 is closed to prevent outside air from penetrating into the pumping pipe 30.

Subsequently, the fluid storage valve 38 is opened to discharge the water in the pumping pipe 30, and the backflow prevention valve 36 is opened with a time difference. When the fluid storage valve 38 is opened, water in the pumping pipe 30 is discharged to the drain 20, and the discharged water is dropped and converted into kinetic energy to generate a vacuum pressure in the pumping pipe 30 to the rear.

At this time, the falling speed is a variable for generating a vacuum pressure may optionally open the air vent 54 installed at the highest point (T) of the pumping pipe (30).

Continuously falling water sucks up the water in the opposite pumping pipe 30 on the basis of the highest point T, and starts to pump the water of the reservoir 10.

The pumped water as described above is pumped continuously, the water is discharged through the outlet 34 of the pumping pipe (30).

In particular, in the present invention, in addition to the method of filling the water pumping pipe 30 by the operation of the vacuum pump 60 is provided with a separate pumping pump 65 to pump the water directly to the connecting pipe 50 to the pumping pipe ( 30) may be filled with water. At this time, the third blocking valve 48 and the fourth blocking valve 52 are closed.

On the other hand, the gas contained in the water passing through the pumping pipe 30 while the drainage is continuously proceeded to the highest point (T) of the pumping pipe 30 can no longer move along the pumping pipe 30 Accumulated in the pumping pipe 30, and as the accumulation amount increases, the amount of water drained may be gradually reduced or the drainage may be stopped.

The gas contained in the water passing through the pumping pipe 30 is discharged out of the pumping pipe 30 through the air vent 54.

In the present invention, when the water in the pumping pipe (30) is not left in the flowing state in the winter (cold), there is a risk of freezing of the pumping pipe (30).

In order to prevent this it is necessary to discharge the water out of the pumping pipe (30). The water in this pumping pipe 30 is preferably discharged to a reservoir or reservoir. To this end, the present invention opens the air vent 54 in a state where the non-return valve 36 and the fluid storage valve 38 are opened to discharge the water in the pumping pipe 30.

In addition, water located in the direction of the non-return valve 36 based on the highest point T is discharged to the reservoir 10 through the inlet 32.

In the present invention, it is also possible to perform various functions using the above drainage device. That is, when the drainage is started along the pumping pipe 30 and continuously flows from the reservoir 10 to the tank 20, the pumping pipe 30 preferably stores fluid with the highest point T of the pumping pipe 30. A small hydro power installation, not shown, may be provided between the valves 38 to obtain electricity. At this time, in order to rotate the turbine of the generator, the flow rate of water should be considered bar installed at intervals of 50m or more spaced apart from the installed turbine, but installed on the downwardly extending pumping pipe (30).

The electricity obtained by the small hydro generator installed on the pumping pipe 30 may be used as electric power for operating the vacuum pump 60, or may be used as a neighboring household electricity in which the pumping pipe 30 is embedded.

In other words, as will be clear from the electric description, the present invention can prepare for flooding by pumping water at a relatively high place by using potential energy of water and discharging it to a drainage place at a low place. It can be widely applied to facilities.

In the present invention, it goes without saying that various other modifications are possible. For example, if necessary, the reservoir 70 is installed at a position higher than the reservoir 10 in the drainage reservoir 20 discharged as shown in FIG. 4, and the pipe 80 is installed to install the reservoir at a high place ( The water of the drain 20 may be reversely supplied to 10).
That is, when the water in the reservoir 20 is sucked by the temporary power M installed in the suction pipe 84 and pumped into the reservoir 70, the water in the reservoir 70 is continuously dropped through the pipe 80. At this time, a vacuum pressure is generated in the water storage pipe 86 by the generated drop kinetic energy, and the vacuum pressure sucks the water in the reservoir 20 through the water storage pipe 86 to drain the water discharged into the water pipe 80. Refill with (70). At this time, the water sucked through the reservoir pipe 86 is continuously sucked by the vacuum pressure and starts to be sucked into the reservoir 70 to stop the temporary power (M).
When the water of the drainage reservoir 20 is continuously sucked through the reservoir pipe 86 as described above, the water is discharged to the reservoir 10 through the reservoir 70 and the pipe 80.
Preferably, the pipe 80 connected to the reservoir 70 is located at a lower position than the reservoir 86.

In addition, as another embodiment of the present invention, as shown in Figure 4, the water inlet 82 is installed at the highest position (T) of the pipe 80 connected to the reservoir 10, the water inlet 82 Injecting is continuously dropped into the reservoir 10 through the pipe 80. The falling kinetic energy generates a vacuum pressure from the highest position (T) to the pipe (80) in the direction of the reservoir 70, the vacuum pressure sucks water in the reservoir 70 and discharges it toward the reservoir (10). .
The discharged water of the reservoir 70 generates a vacuum pressure in the reservoir pipe 86 again, and the vacuum reservoir pipe 86 sucks water from the reservoir 20 and discharges it into the reservoir 70, and the reservoir ( The water of 70 is again sucked into the pipe 80 and finally discharged to the reservoir 10.
At this time, since the water in the reservoir 70 is sucked into the pipe 80 for the vacuum pressure of the reservoir pipe 86, the water in the reservoir 70 continuously through the suction pipe 84 using the above-mentioned temporary power (M). Can be filled.

Further, as shown in FIG. 5, the fifth shutoff valve 90 is installed on the vacuum pipe 40, and the second drain pipe 92 serving the same role as the first drain pipe 42 is provided below. Branching may be configured to communicate with the pumping pipe (30).

That is, the first and second shutoff valves 44 and 46 are opened, and the third, fourth and fifth shutoff valves 48, 52 and 90 are closed. (38) is closed) and when the vacuum pump 60 is operated, the vacuum pipe 40 below the fifth shut-off valve 90 is vacuumed by the vacuum pump 60, and the vacuum is continuously pumped. The vacuum pipe 40 below the third shut-off valve 48 in the direction of the connection pipe 50 and the reservoir 10 is evacuated to suck water from the reservoir 10 and the reservoir (30) in the pump pipe 30. The water of 10) may be filled to the highest point T or the first shutoff valve 44 may be opened using the pump pump 65. Accordingly, all modifications existing within the spirit and scope of the present invention are included in the claims.

As described above, according to the present invention, it is possible to reduce the installation and management cost of a huge dam to prevent flooding, to prevent the environmental destruction problem caused by the formation of the flooded basin by the installation of the dam, drained by a large diameter pumping pipe Even if the device is installed, the water required for the drainage operation can be provided in the pump pipe by laying a vacuum pipe having a small diameter can exhibit an excellent effect in terms of energy efficiency.

For example, if the water of Chungju Lake becomes flooded and discharged by opening the floodgate, the river will be flooded and flooded, which can cause enormous property damage. By draining the water to the nearby Daecheong Lake, the discharge amount of the Chungju Lake is reduced to prevent flooding.
