As shown in FIGS. 1 to 6, the water intake device for selectively extracting water in accordance with the present invention includes a water intake portion 110, a buoyancy portion 130, an inclined inflow portion 11, a control portion 220, and a tilting outflow portion 13.

Here, selective water extraction refers to selective acquisition of surface water, middle water and deep water by adjusting the water depth.

The water intake portion 110 of the first embodiment includes a water intake hole 115, an inflow portion 120, a weight portion, an extension portion 150, and a buoyancy portion 130.

The water intake portion 110 preferably takes the shape of a triangular pyramid or an inverted pyramid, and the inside is empty to allow water to flow in.

The water intake hole 115 is formed in the center of the lower surface of the water intake portion 110 and is connected to the inclined inflow portion 11 to allow surface water to flow into the inclined inflow portion 11.

The inflow portion 120 is a protrusion having a plurality of triangles formed on the upper side of the water intake portion 110.

Here, preferably, the inflow portion 120 is formed around the upper side of the water intake portion 110 and is formed to protrude in a triangular shape, but is not limited.

That is, the inflow portion 120 may be formed in a semicircular shape or a polygonal shape to change the amount of water taken according to different water intake purposes.

A weight portion (not shown) is attached to the water intake portion 110 and adjusts the water depth of the water intake portion 110 by weight gain.

One side of the extension 150 is formed to be elongated.

The extension portion 150 is formed to be elongated at the same angle on one or both sides of the upper side of the water intake portion 110 and has the same height as the upper side of the water intake portion 110 to allow water to flow into the water intake hole 115.

Here, the extension portion 150 serves to increase the water intake area to increase the water flow rate of the water intake hole 115.

Further, here, it is preferable that the extension portion 150 is formed on the upper side of the inflow portion 120.

The buoyancy unit 130 is attached to the water intake unit 110 and applies buoyancy to the water intake unit 110.

Here, the buoyancy portion 130 is preferably tubularly coupled to the upper side of the water intake portion 110 or symmetrically coupled to both sides of the upper side.

One side of the inclined inflow portion 11 is connected to the above-mentioned water intake hole 115 and flows into the above The surface water of the water hole 115 is taken out, and the length and position are adjusted when the water taking portion 110 is moved by the buoyancy portion 130, the weight portion, and the water flow.

Here, the inclined inflow portion 11 includes the position fixing portion 212.

The position fixing portion 212 is formed at a portion that is in contact with the ground and fixes the inclined inflow portion 11.

That is, it is preferable that the position fixing portion 212 fixes the position of the inclined inflow portion 11 by the weight or by a joint member using the ground and the inclined inflow portion 11, for example, bolting or the like.

Further, the control unit 220 is connected to the inclined inflow portion 11 and the inclined outflow portion 13 and moves to the inclined outflow portion 13 by adjusting the amount of water taken in by the surface water sucked from the water intake unit 110.

Here, the control unit 220 further includes a first regulating valve that allows or blocks the flow of the outside air to the inside of the control unit 220, and an air pump that discharges the air inside the control unit 220 to the outside.

That is, preferably, the control unit 220 controls the output of the air pump to form a vacuum state by the flow of the air in the inclined outflow portion and the inclined inflow portion 11, thereby generating a siphon phenomenon, thereby adjusting the amount of water taken.

At this time, the siphon phenomenon occurs in a state where the inclined inflow portion 11 and the oblique outflow portion 13 are filled with water and the outside air is blocked. Preferably, the tilting is performed by a water pump (not shown) or a shunt tube 227. The outflow portion 13 is filled with water to maintain a vacuum state.

Specifically, the control unit 220 stops the siphon phenomenon by opening the above-described first regulating valve to cause external air to flow into the inside of the control portion to block the flow of water, or by closing the above The first regulating valve and starting the air pump discharge the air inside the control portion to the outside to start the siphon phenomenon.

That is, when the first regulating valve is opened, water does not flow, and if the first regulating valve is closed and the air pump is turned on, the water originally in the inclined inflow portion passes through the control portion 220 and is discharged to the inclined outflow portion 13.

In addition, the control portion may further include a shunt tube 227 and a second regulating valve (not shown).

Here, one side of the branch pipe 227 is submerged under the water surface, and the other side is combined with the above-described outflow portion 13 to move the water flowing from the one side to the other side, thereby inducing a siphon phenomenon.

Further, a second regulating valve (not shown) opens the water gate to allow water to flow into the above-mentioned branch pipe 227, or closes the water gate to block the inflow of water.

The inclined outflow portion 13 allows the surface water flowing into the control portion 220 to flow out.

That is, preferably, the inclined outflow portion 13 discharges the surface water flowing in through the control portion 220 to the outside.

Here, the inclined outflow portion 13 includes a fixing member 232 and an outflow regulating plate 234.

The fixing member 232 is fixedly formed inside the tube.

The outflow regulating plate 234 has a plate shape, and one side of the outflow direction in which the water supply flows out is hingedly coupled to the fixing member, and the other side in the inflow direction in which the water supply flows in is coupled to the fixing member by a spring that applies elasticity to the inside.

Here, the spring 236 can be combined with the fixing member 232 and the outflow regulating plate 234 in two ways, and has a coil spring shape between the fixing member 232 and the outflow regulating plate 234. The combination is bonded to the rear side of the fixing member 232 and the outflow regulating plate 234 in the form of a leaf spring.

Therefore, the other side of the outflow regulating plate 234 which is coupled to the fixing member 232 by the spring 236 is opened in accordance with the flow rate to reduce the outflow amount when the flow rate is fast, and does not decrease the outflow amount when the flow rate is slow.

Here, the spring 236 adjusts the extent to which the outflow regulating plate 234 is opened in accordance with the flow rate of water flowing through the inside of the inclined outflow portion 13.

That is, according to the strength and the torsion force of the spring 236, the degree of opening of the outflow regulating plate 234 according to the flow velocity of the water is different, thereby adjusting the outflow amount.

Further, the inflow portion is combined with one or more inflow portions formed on the four surfaces of the water intake portion, and the inclined inflow portion 11 separates the oblique inflow portion 11 and is connected to the water intake portion.

Further, the buoyancy portion 130 is tubular and adjusts the buoyancy by adjusting the internal air pressure.

Figure 7 is a cross-sectional view of a siphon spillway A in accordance with a second embodiment of the present invention.

As shown in Fig. 7, at the lower end of the inclined outflow portion 13, a lower end connecting pipe 5 and an upper connecting pipe 6 are coupled in a "V" shape. The lower end connecting pipe 5 is in the form of an extension of the outflow port of the inclined outflow portion 13 in the horizontal direction, and the upper connecting pipe 6 is connected to the end of the lower end connecting pipe 5 and inclined upward. Preferably, the upper end notch connecting pipe 7 of the upper connecting pipe 6 is formed to be elongated in the form of a level.

Since the inclined outflow portion 13, the lower end connecting pipe 5, and the upper connecting pipe 6 have a "V" shape, water may accumulate in the intermediate portion between the inclined outflow portion 13 and the upper connecting pipe 6. As described above, for the start of the siphon spillway A, most of the outflow port 19 where the water needs to be filled to the inclined outflow portion 13 is The height of the submerged, and the water accumulated in the lower end connecting pipe 5 plays such a role.

The lower end connecting pipe 5, the upper connecting pipe 6, and the notch connecting pipe 7 are formed of the same material and a similar form as the inclined outflow portion 13, thereby forming an integral communication pipe. Therefore, it is not necessary to form another downflow tank 8 on the outer side of the lower side of the siphon spillway A in order to accommodate a certain amount of water. Since the lower end connecting pipe 5 and the upper connecting pipe 6 are cylindrical pipe structures, they can be buried in the interior of the dam or the dam. Further, since the water is discharged to the outside through the lower end connecting pipe 5, the upper connecting pipe 6, and the notch connecting pipe 7, there is no need to worry that the water inside thereof permeates into the interior of the dam or the dam or leaks.

Figure 8 is a cross-sectional view showing a dam or dam D in which a siphon spillway A of the second embodiment of the present invention is disposed.

As shown in FIG. 8, the siphon spillway A of the present invention is provided with an integral lower end connecting pipe 5, an upper connecting pipe 6 and a notch connecting pipe 7 which can replace the downflow water tank 8 and the water tank masonry wall 9, without additional external structure. . Therefore, it is not difficult to induce the siphoning effect only by the siphon spillway A, and the integrated siphon spillway A is buried in the interior of the dam and the dam in a state where only the lower side outlet port 19 is opened.

At this time, the upper end portion of the siphon spillway A is covered with the Jiangyong concrete structure or the like, and therefore the usage rate of the upper end portion is also increased.

That is, the upper portion of the siphon spillway A can be used for landscaping or as a roadway. In addition, when constructing the dam or dam, it is not necessary to install another structure in the middle, and the function of the siphon spillway A can be automatically completed by embedding the siphon spillway A inside. In addition, it can prevent problems such as water penetration into the concrete interior or the concrete downflow water tank and the water tank wall.

Figure 9 is a cross-sectional view showing a siphon spillway A of a water intake device for adjusting water depth to selectively take water according to a third embodiment of the present invention.

As shown in FIG. 9, a siphon spillway A of a water intake device for adjusting water depth for selectively taking water according to a third embodiment of the present invention includes: a siphon body 1 having a slanting inflow from the water storage tank W to the upper end D1 of the dam D a portion 11 extending from the inclined inflow portion 1 and extending over the dam D and an inclined outflow portion 13 formed to extend downward along the slope surface of the dam D2; the water level adjusting tube 4 from the siphon body The inclined inflow portion 11 extends through the bank D to the inclined outflow portion 13 and is provided with an opening and closing valve 21 at the end portion on the side of the inclined inflow portion 11; the branch pipe 3 is provided at the end portion of the water level adjusting tube 4 on the side of the inclined inflow portion 11 Adjusting the water level of the other height and providing an opening and closing valve at one end; the opening and closing valve 41 is provided at an end portion adjacent to the overflow tank of the inclined inflow portion 11 , bent and extended upward so that the other end portion is located on the extension portion, and An opening and closing valve 41 is provided in the middle.

Here, preferably, the siphon body 1 is a subordinate concept of the siphon spillway A, and includes only the inclined inflow portion 11, the extension portion, and the inclined outflow portion 13.

In the third embodiment of the present invention, only one branch pipe 3 is provided in the above-described water level adjusting pipe 4, but a plurality of pipes may be provided at different heights as needed to finely adjust the water level. The flow altering device 15 provided at a predetermined interval in the inclined outflow portion 13 of the siphon body 1 fills the first flowing water and flows downward to form a waterfall effect, and discharges the air in the siphon body 1 by the waterfall effect, thereby siphoning A vacuum state is formed in the main body 1 to exhibit a complete siphon effect.

The lower end portion 42 of the highest full water level in the winter close to the air discharge portion 2 is moved upward by 2 cm from the full water level in the winter, and the upper end portion 21 is communicated to the upper portion of the extended portion 12 of the siphon body 1.

The siphon spillway A of the water intake device for adjusting the water depth for selectively taking water according to the second embodiment of the present invention having the above-described structure is expected to have large rainfall such as concentrated rainfall or flood When it is necessary to discharge the water in the reservoir in advance or to prevent the concentrated rainfall or flood from being required to drain the storage water of the reservoir, open the opening and closing valve 43 provided on the water level adjusting pipe 4 and close the other opening valve 31, 23, the water in the water storage tank W flows into the water level adjusting pipe 4 and flows to the inclined outflow portion 13 of the siphon body 1, so that the water flowing into the inclined outflow portion 13 in the siphon body 1 is filled until the flow converting device 15 flows downward. Forming a waterfall effect, and the air in the siphon body 1 is discharged together with the outflowing water due to the above-mentioned waterfall effect, forming a vacuum state in the siphon body 1, so that the water in the water storage tank W passes through the vacuum state in a few seconds or tens of seconds. The siphon body 1, that is, the inclined inflow portion 11 flows out and is discharged through the inclined outflow portion 13 through the extension portion, thereby easily maintaining the water level of the reservoir in the water surface of the emergency drainage period.

Fig. 10 is a schematic longitudinal cross-sectional view showing a common reservoir for comparing the water storage amount of the reservoir of the second embodiment of the present invention.

In addition, water can be supplied to the agricultural tank cover in the spring, and the water level close to the height of the dam can be stored during the motive or busy season of November to February when the rainfall is insufficient. This is because, in the winter and busy seasons, there is less rain, there is no need to worry about the sharp rise of the water level in the reservoir, and a lot of agricultural water is needed. When the water exceeds the maximum full water level in the winter and is discharged through the siphon body 1 as the highest water level in the above-described above-described present invention, the water passing through the siphon body 1 passes through the air discharge portion 2 in a state where the opening and closing valve 23 is closed. The lower end portion 22 is such that the height of the lower end portion 22 is lower than the height of the full water level water, so that the lower end portion 22 passes the water level ratio of the full water level to block the inflow of air, and the full water level flows to the inclined outflow portion 13 of the siphon body 1, The water flowing into the inclined outflow portion 13 in the siphon body 1 is filled up to the flow converting device 15 and flows to the lower portion to form a waterfall effect, because the air in the siphon body 1 is discharged together with the outflow water, and is formed in the siphon body 1 due to the waterfall effect. In the vacuum state, the above siphon effect is automatically generated, and water is easily discharged, so even The water level of the reservoir becomes higher than the existing full water level, and it can automatically induce the siphon effect to effectively discharge water when it exceeds the highest water level in winter, so that there is no need to worry about the occurrence of a break or flood, and, as shown in Figure 1, it can be stored. Up to 260% more water than the existing full water storage.

In addition, in June to August when there is a lot of rainfall, since it is not necessary to store water, the water level of the branch pipe 3 which is equal to the existing full water level can be maintained. That is, when the opening and closing valve 33 of the branch pipe 3 is opened at the normal water level and the opening and closing valves 43 and 23 are closed, the water flows through the branch pipe 3 through the water level adjusting pipe 4 to the siphon body of the inclined outflow portion 13 when the rain exceeds the normal full water level. 1 and filled into the flow converting device 15 and flowing to the lower part to form a waterfall effect, because the air in the siphon main body 1 is discharged together with the outflowing water, and a vacuum state is formed in the siphon main body 1 so that the water in the water storage tank W is Within a few seconds or tens of seconds, the siphon body 1 in a vacuum state, that is, the inclined inflow portion 11 flows out and is discharged through the inclined outflow portion 13 through the extension portion, so that it is easy to discharge water exceeding the normal full water level in the summer, and maintain the water level of the reservoir at The water level of the normal full water level.
