Description

Facility for water supply and beforehand discharge using siphon triggering pipe

The present invention relates to a water supply and pre-discharge facility, in particular, by inserting the outlet of the trigger pipe designed to be deeper from the surface than the inlet through the side of the effluent pipe, even if the low water quantity does not meet the pre-set discharge standard Water supply and pre-discharge facilities triggering the discharge of water downstream through von Yeosu.

In Korea, there is a big variation in precipitation and seasonality. Recently, abnormal patterns of different patterns continue to appear. The most obvious countermeasure against climate change is to secure water reservoirs such as reservoirs and dams. In Korea, the amount of water available per capita is only one sixth of the world average, but water consumption is high. As a result, water use exceeds 40% of available water resources, which leads to a very poor water stress. Considering climate change and domestic water resources situation, more real-time operation and efficient utilization of existing water resources such as dams is very important.

The time when water is stored in dams or reservoirs is the summer rainy season. However, to prevent flooding during the rainy season, it is necessary to increase the reservoir capacity by discharging the water stored in the dam or reservoir downstream before the summer rainy season begins, in late spring. On the other hand, considering the late autumn, winter, and early spring climates, the waters stored during the summer rainy season should be confined to dams or reservoirs, and of course, prepared for drought.

Water from dams or reservoirs is discharged downstream through certain gates. Opening and closing of gates is also accomplished by automatic management systems, but it is common for dams and reservoir managers to determine and implement them on a case-by-case basis. If a person opens and closes a dam or reservoir gateway, it may be accurate on the one hand, but depending on the stewardship, the timing or amount of water released will vary.

The water stored in the dam reservoir must have a certain amount of water flowing downstream for the purpose of agriculture and so on. However, there is a disadvantage that the management is required because the opening and closing of the gate to be adjusted automatically or manually.

Recently, using the principle of siphon, when a certain standard of water stored in a dam or a reservoir is reached, the stored water is discharged through a siphon tube by itself.

Referring to Figure 1, the position of the inlet 12 and the outlet 32 of the siphon Yeosu channel used in the conventional siphon Yeosu channel technology (Registration No. 10-0738903, July 6, 2007) is the first installation As it was fixed, it was fixed at the low water discharge time when it was naturally discharged through the siphon pipe. In other words, even when water is required downstream, there is a disadvantage in that water is not discharged downstream through a siphon tube, ie, a siphon channel, if water is stored that is less than a predetermined low water quantity, which is a condition for discharge.

The technical problem to be solved by the present invention, by using a siphon trigger pipe inserted into the side of the siphon channel to the outlet of the siphon trigger pipe designed to be deeper than the inlet water outlet, the discharge standard is set in advance It is to provide a water supply and pre-discharge facility that triggers the discharge of water downstream through the siphon channel, even if it does not reach.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. Like reference numerals in the drawings denote like elements.

Figure 2 is an embodiment of the water supply and pre-discharge facility using the siphon trigger pipe according to the present invention.

Referring to FIG. 2, the water supply and pre-discharge facility 200 using the siphon trigger pipe according to the present invention includes a siphon filter channel 220 and a siphon trigger tube 230.

The siphon flow channel 220 has a first diameter of a predetermined size and consists of a waste water pipe 222 for discharging water flowing from the end of the water inlet 221 to the end of the water outlet 223. Yeosu inlet 221 is installed inside the reservoir 210, the yeosu pipe 222 is installed in the downstream direction along the slope 212 of the reservoir 210 over the embankment 211 of the reservoir 210. , Yeosu outlet 223 is located inside the downstream water tank 240 having a constant depth that is a lower position (d1) than the Yeosu inlet 221.

The siphon triggering pipe 230 has a second diameter of a predetermined size, and is composed of a triggering pipe 232 for discharging water flowing from the triggering inlet 231 which is one end to the triggering outlet 233 which is the opposite end. The trigger pipe 232 penetrates the reservoir 210 in a horizontal direction, the trigger inlet 231 is installed inside the reservoir 210, and the trigger outlet 233 is installed in the downstream direction of the reservoir 210, and triggered. The outlet 233 is inserted into the sewage pipe through hole 224 installed in the downstream direction along the inclined surface 212 of the reservoir 210 among the side surfaces of the sewage pipe 222 in the second diagonal direction. Here, the second oblique direction refers to a direction in which the position of the drain pipe through hole 224 is lower than that of the outer through hole 214 (d5).

The trigger inlet 231 may be installed at a position d2 lower than the water surface in comparison with the inlet 221, and the trigger outlet 233 may be installed at a position d4 higher than the outlet 223. The trigger outlet 233 is installed at a position d3 lower than the trigger inlet 231.

It is preferable that a 1st diameter is large compared with a 2nd diameter.

The portion of the middle portion of the siphon channel 220 that passes over the embankment 211 of the reservoir 210, the siphon channel 220 in a manner of reducing the negative pressure formed inside the siphon channel 220. A sewage pipe pressure reducing valve 225 is installed to adjust the pressure of the water) and the amount of water flowing through the siphon filtration channel 220.

At least one of near the trigger inlet 231 and near the trigger outlet 233 constituting the siphon trigger tube 230, a trigger pipe flow control valve 234, 235 for reducing the internal air pressure of the trigger tube 232. Is installed.

At least one of the Yeosu inlet 221 and the triggering inlet 231 is preferably provided with vortex prevention facilities (226, 236).

Figure 3 is another embodiment of the water supply and pre-discharge facility using the siphon trigger pipe according to the present invention.

Another embodiment 300 of the water supply and pre-discharge facility using the siphon trigger pipe according to the present invention shown in Figure 3 is compared with the embodiment shown in Figure 2, the trigger pipe 232 is a reservoir 210 ) Through the first diagonal direction rather than the horizontal direction, and the end portion of the Yeosu outlet 223 is formed in the "U-shaped" or "V-shaped" form (dotted circle) Since it is the same except that the position is higher than the lowest point of the yeosu pipe 222, it will not be described in detail here.

The trigger tube 232 penetrating the reservoir 210 horizontally or in a first oblique direction may be a design option that can be selected depending on the shape, material and any need of the dike.

The first oblique direction is a direction in which the position of the outer through hole 214 formed in the outer surface of the reservoir 210 is lower than the inner through hole 213 formed in the inner surface of the reservoir 210.

2 shows the case where the effluent outlet 223 is installed inside the downstream water tank 240, and in FIG. 3, the portion (dotted source) where the effluent tube 222 and the effluent outlet 223 contact each other is "V." It shows the case bent in the form of ". The reason why the Yeosu outlet 223 is to be installed in the downstream water tank 240 and the reason that the portion (dotted source) where the Yeosu pipe 222 and the Yeosu outlet 223 contact each other should be bent in the form of "V". This is because the inside of the sewage pipe 222 may be a vacuum when the Yeosu outlet 223 is submerged in water, and the siphon phenomenon may be induced when the inside of the Yeosu pipe 222 is vacuumed.

Hereinafter, the operation of the water supply and pre-discharge facility using the siphon trigger pipe according to the present invention will be described.

4 illustrates a process in which water flows through the siphon channel by the siphon trigger tube.

4A illustrates a case in which water stored in the reservoir 210 falls short of the inlet 231 as well as the inlet 221. In this case, the water stored in the reservoir 210 may not be discharged through the effluent pipe 222 and the trigger pipe 232. In addition, the air pressure inside the effluent pipe 222 and the inside of the trigger pipe 232 is equal to atmospheric pressure.

4B illustrates a case in which the water stored in the reservoir 210 does not reach the water inlet 221 but affects the trigger inlet 231. Since the trigger inlet 231 is installed at a higher position than the trigger outlet 233, the water of the reservoir 210 opens the trigger outlet 233 through the trigger pipe 232 by the water pressure of the water stored in the reservoir 210. Is released downstream through. Since the diameter of the trigger tube 232 is generally designed to be thin, the amount of water discharged downstream through the trigger tube 232 will not be large. Although the effluent outlet 223 is submerged in the discharged water, the discharged water penetrates into the inside of the effluent pipe 222 only as high as the downstream water tank 240. Since the Yeosu inlet 231 is open, it can be seen that the interior of the Yeosu tube 222 is not in a vacuum state.

4C illustrates a case in which the water stored in the reservoir 210 reaches the trigger inlet 231 as well as the inlet 221. At this time, the water stored in the reservoir 210 is not discharged downstream through the yeosu pipe 222, but the yeosu inlet 221 is blocked, and the air inside the yeosu outlet 223 along with the water entered through the trigger pipe 232 As it exits to the outside through), the interior of the yeosu pipe 222 becomes a vacuum. Even when the inside of the effluent pipe 222 is in a vacuum state, a small amount of water is continuously discharged downstream through the trigger pipe 232. Since the water discharged downstream through the trigger pipe 232 to discharge the air inside the yeoseo pipe 222 along the yeosu outlet 233 together, the yeosu pipe previously had the same height as the yeosu outlet 223 ( The water filling the inside of the 222 gradually rises along the yeosu pipe 222 and starts to form a water column, and at the same time, the water stored in the reservoir 210 also rises at the yeosu inlet 221 to form near the yeosu outlet 223. It forms a water column with the same height as the water column. As the air inside the sewage pipe 222 continues to escape through the Yeosu outlet 223, the air pressure in the sewage pipe 222 falls, and thus the water column formed at both ends of the sewage pipe 222. The height will increase.

4D shows that as the height of the water column formed on the side of the inlet 221 increases to the horizontal free pipe 222 directly above the bank 211, the horizontal portion of the free pipe 222 on the bank 211 is eventually formed. The case where the flow to the Yeosu outlet 223 is described below. 4D illustrates the state using the true siphon principle.

Water supply and pre-discharge facility using the siphon trigger pipe according to the present invention is to discharge the water of the reservoir 210 downstream through the yeosu pipe 222, in particular, only the siphon yeoseo 220 installed In this case, it is possible to supply the water downstream even if the conditions for supplying the water downstream are not met.

In addition, the siphon triggering pipe 230 is not only a function of triggering the main function of the siphon channel 220, but also as shown in Figure 4b, the water in the reservoir 210 is not enough, but still supply of water from the downstream If desired, this can be achieved without opening the gateway installed in the reservoir 210.

By using the sewage pipe pressure reducing valve 225 installed on the upper portion of the sewage pipe 222, it is possible to control the amount of water discharged downstream through the sewage pipe 222. Using the triggering pipe flow rate control valves 234 and 235 installed in the triggering pipe 232 may control the amount of water discharged downstream through the triggering pipe 232. By adjusting the flow rate control valves 234 and 234, the flow rate of the water flowing through the inside of the triggering pipe 232 is adjusted, and the water flowing through the triggering pipe 232 completely fills the inside of the triggering pipe 232. Use it to proceed. When the flowing water does not completely fill the inside of the trigger pipe 232, no negative pressure is formed in the trigger pipe 232, which causes a decrease in flow velocity and flow rate, and thus, in the siphon channel 220. This is because the phone phenomenon may be delayed or not occur at all.

If the flow control valve 235 installed near the trigger outlet 233 of the trigger pipe flow control valves 234 and 235 installed in the trigger pipe 232 while the water is completely filled in the trigger pipe 232, The inside of the trigger tube 232 will be completely filled with water. While maintaining this state, when the reservoir 210 is filled with less water, and only reaches the trigger inlet 231, when the flow control valve 235 is opened, the water in the reservoir 210 is opened. It will be discharged downstream through the trigger tube 232. That is, if the height of the water stored in the reservoir 232 is normal, even if it is not enough to be discharged downstream through the trigger tube 232, using the water filled in the inside of the trigger tube 232 to the reservoir 210 A function may be performed to allow the stored water to be discharged downstream.

In the vortex prevention facilities 226 and 236 installed at the inlet 221 and the trigger inlet 231, the water flowing through the interior of the effluent tube 222 and the trigger tube 232 is the effluent tube 222 and the trigger tube 232. ) To move in a state filled with full.

In the above description, the technical idea of the present invention has been described with the accompanying drawings, which illustrate exemplary embodiments of the present invention by way of example and do not limit the present invention. In addition, it will be apparent to those skilled in the art that various modifications and imitations can be made without departing from the scope of the technical idea of the present invention.
