Description

{A Bottom-water of Reservoir Discharge Device}

Unlike the ocean where ocean currents are generated, it is difficult to vertically circulate water between the upper water layer and the lower water layer. In particular, the heating of the surface layer of the lake by the summer sun strongly increases the surface water temperature, and the thermocline is formed strongly, which further blocks the vertical circulation, making circulation of the low layer water more difficult. As a result, green algae phenomenon occurs due to eutrophication in the lower layer water of the lake, and the turbidity caused by the flood in the summer does not improve even over time, causing water pollution due to water pollution. In addition, the low - level water of this lake has stagnated at the bottom of the lake for a long time without exchange (circulation) with the surface waters and maintains eutrophication and anaerobic condition.

In the case of recently installed dams or reservoirs, it may be included in consideration of a device capable of discharging the low-level water of such a lake in the design stage. However, since such a device is not equipped in the conventional facility, It is necessary to install and use a device capable of circulating or discharging the low-level water.

Conventional devices, however, either merely forcibly inject oxygen into the lower layer water of the lake or to bring the lower layer water up to mix with the surface waters of the lake, or to force the lower layer water of the lake to be discharged outside the lake However, when the low-level water of the lake is simply discharged to the outside as in the prior art, the eutrophication or the anaerobicization has already proceeded and the contamination of the river around the lake is increased due to the discharge of the contaminated low-level water.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear.

1 to 11, a low-level water discharging device according to an embodiment of the present invention includes a low-level water discharging device 10 for discharging low-level water of a lake 11 and discharging the water over the dam 12, And the other end of the siphon pipe (20) is located at a height lower than the height of the dam (12) over the dam (12); A fixing sinker (30) for stably fixing one end of the siphon pipe (20) to the bottom of the elevator (11); A safety rope 40 installed along the siphon pipe 20 so as to extend over the siphon pipe 20 and the siphon pipe 20 so as to extend over the siphon pipe 20 and to securely operate the siphon pipe 20 when the siphon pipe 20 is disassembled; A pipe sinker 50 for fixing the middle of the siphon pipe 20 installed in the water of the lake 11; And a safety buoy 60 connected to one end of the siphon pipe 20 by the mooring rope 70 to float on the water surface of the sail 11 to indicate the position of one end of the siphon pipe 20, siphon operation to discharge the lower layer water of the lake 11 to the outside.

2, one end of the siphon pipe 20 is located at the bottom of the arc 11 and the other end of the siphon pipe 20 is connected to the dam 12, more specifically, To prevent the risk of collapse of the weir 12 when the height of the float 12 is equal to or greater than a predetermined height, the float 13 is formed to have a height slightly lower than the maximum height of the weir 12, The lower layer water at the bottom of the lake 11 flows into one end of the siphon pipe 20 by using the siphon principle according to the change in the water level of the lake 11 so that the siphon pipe 20 So that it can be discharged to the outside through the other end. The process of discharging the low-level water through the siphon pipe 20 according to the change of the water level of the lake 11 will be described later. In the present invention, the siphon pipe 20 is formed of a flexible material (for example, a material such as a high-pressure hose using rubber or synthetic resin) that can withstand a high pressure while being bendable, (20) can be easily and easily installed while being lowered into the water of the lake (11) without an operation such as the construction of a separate water film. That is, in the case of a siphon pipe formed of a rigid material which is not bent, such as a conventional steel pipe or a stainless steel pipe, a siphon pipe 11 is provided for installing the entire siphon pipe over the dam 12 from the bottom of the siphon 11, It is necessary to connect the steel pipe (or stainless steel pipe) at the bottom and the bottom of the dam (12), and it is necessary that the installation work of the installation site is performed beforehand and that the installation and dismantling (maintenance) Time and money-consuming problems. Therefore, if the siphon pipe 20 is formed of a flexible material capable of being bent and able to withstand high pressure as in the present invention, the siphon pipe 20 may be pre- ) Is made of a soft material so that connection and assembling work at the site (usually at the upper part of the dam 12 can also be easily performed)) is fixed to the drainage channel 13 and the other end side of the siphon pipe 20 The siphon pipe 20 can be naturally bent while being bent in accordance with the bent part such as the vicinity of the boundary between the lower part of the dam 12 and the floor of the elevator 11 in the process of gradually lowering the siphon pipe 20 into the arcade 11 The description of the safety rope 40 and the piping sink 50 used in the process of installing and fixing the siphon pipe 20 will be described later) The installation work can be performed more easily, and the installation and dismantling (maintenance) can be performed easily and quickly. In the present invention, the siphon pipe 20 is not installed at a different place in the dam 12, but the siphon pipe 12 is provided in the seawater 12 where the surface water (water near the water surface) Even when the low-level water of the lake 11 is discharged through the siphon pipe 20, it is mixed with the surface waters of the lake 11 that sweeps the waterway 13 all the time, Thereby minimizing the influence on the change in the surrounding water quality (a detailed description thereof will be provided later).

8, the fixed pier 30 is configured to stably fix one end of the siphon pipe 20 to the bottom of the pier 11. The piercing pier 30 has a predetermined weight (a hexahedron shape) One end of the siphon pipe 20 is fixed on the weight 310 and then the upper part of the spheric pipe 310 and the siphon pipe 20 are surrounded by the net 320 and the lower layer water is supplied to one end of the siphon pipe 20 Foreign matter or the like at the bottom of the ladle 11 is firstly filtered by the netting 320 in the course of the inflow, thereby preventing clogging of the siphon pipe 20 due to foreign matter or the like. Further, a separate connecting hook 330 may be formed in the fixing pier 30 to provide a portion where the mooring rope 70 or the safety rope 40 to be described later can be connected and fixed.

The safety rope 40 is installed along the bottom of the arcade 11 and along the dam 12 or connected to the siphon pipe 20 for safe operation when the siphon pipe 20 is dismantled. 9, for example, the safety rope 40 extends equally along the longitudinal direction of the siphon pipe 20 and is connected to a siphon pipe (not shown) 20). As described above, the safety rope 40, which is divided and connected to the siphon pipe 20 along the longitudinal direction of the siphon pipe 20, connects the siphon pipe 20 of a soft material to the siphon 11 In the process of installing the siphon pipe 20 in accordance with the curved portion such as the vicinity of the boundary between the bottom of the lake 11 and the bottom of the lake 11 and the bottom of the lake 11, (Safety measures) can be installed in a double (or triple) manner so that the siphon pipe 20 does not fall out of the work or out of position through a process of connecting a work rope or the like to the work pipe 40, Let's do it. Further, even when the siphon pipe 20 is to be maintained or disassembled, the safety rope 40 may be usefully used for lifting up the siphon pipe 20 .

The pipe sinker 50 has a structure in which a middle portion of the siphon pipe 20 installed in the water of the lake 11 is fixed in position. As shown in FIG. 9, the pipe sinker 50 has a predetermined weight And is connected to the middle of the siphon pipe 20 installed along the bottom of the lake 11 to allow the siphon pipe 20 to be fixed without deviating from the fixed position. If the siphon pipe 20 is moved to a position other than the predetermined position, the siphon pipe 20 may be damaged due to friction between the siphon pipe 20 and the bottom of the elevator 11 or the dam 12 The pipe sinker 50 prevents the siphon pipe 20 from being fixed by fixing the position of the siphon pipe 20.

The safety buoy 60 is connected to one end of the siphon pipe 20 by the mooring rope 70 to indicate the position of the one end of the siphon pipe 20 and is floated on the water surface of the mooring 11, As shown in Fig. 11, the safety buoy 60 includes a surface 610 that is exposed above the water surface; A body 620 in contact with the water surface; And a water tank 630. The water tank 630 is protruded on one side of the water tank 630 to distribute the water flow to the left and right sides of the buoy to uniformly distribute the water to the rudder 631 And a mooring hole 632 formed at regular intervals along the vertical direction of the rudder 631. [

The display 610 collectively refers to a portion exposed above the water surface in the buoy, and includes a lighting device 611 for actively and visually displaying whether or not the safety buoy 60 is present, And a retroreflector 612 that allows the position to be detected. The material of the target 610 may be formed of HDPE (High Density Polyethylene), and the inside of the target 610 may be filled with a foamable resin. In particular, a separate UV protection material for preventing discoloration may be applied to the outside due to the characteristics of the target 610 exposed above the water surface.

As shown in FIG. 11 and the like, the support body 620 is provided with the body 610 and the later-described body 610 so as to improve buoyancy and balance (stability) The body 620 may be made of HDPE (High Density Polyethylene), and a foamed resin may be filled in the body 620 to form an outer high density polyethylene (HDPE) HDPE) is partially damaged, the safety buoy 60 can float without being flooded.

11, the overall shape of the non-permeable portion 630 is different from that of the floating body 620 and the non-permeable portion 630, as shown in FIG. 11, And is formed in a conical shape on the distal end portion of the inner tube 630 so that the vertical resistance of the buoys 630 is reduced to a diameter smaller than the outer diameter of the body 620 having a larger diameter, The safety buoy 60 can be prevented from being damaged by moving the safety buoy 60 in conjunction with the sudden change in the water level of the lake 11 such as flood.

11, the rudder 631 is formed as a plate protruding in a vertical direction from one side of the barrel 630. The rudder 631 distributes the flow of water constantly to right and left sides of the buoy, Minimizing shaking. Accordingly, the rudder 631 positioned below the water surface makes the safety buoy 60 unlike other buoys, and thus it can be rotated or shaken infinitely so that the safety buoy 60 and the siphon pipe 20 It is also possible to prevent the mooring rope 70, which connects the mooring rope 30 and the mooring rope 70, from twisting or winding. A plurality of mooring holes 632 are formed at regular intervals along the vertical direction of the rudder 631. The mooring holes 632 are formed by adjusting the positions of the mooring rings 710 coupled to the mooring holes 632, Thereby making it possible to adjust the point at which the rope 70 is coupled to the safety buoy 60. That is, since the shaking or balance of the safety buoy 60 depends on the difference between the upper cross-sectional area and the lower cross-sectional area centering on the point where the mooring rope 70 is coupled to the safety buoy 60, A plurality of mooring holes 632 formed at predetermined intervals along the vertical direction of the rudder 631 may be used to adjust the joining position of the mooring ring 710 and the mooring rope 70 as necessary to provide a safety buoy 60 to be minimized.

Hereinafter, the low-level water discharge process using the low-level water discharge apparatus of the present invention according to the water level change of the lake 11 will be described with reference to Figs.

3, when the water level of the lake 11 is kept lower than the height of the waterway 13 of the dam 12, the water of the lake 11 is discharged to the outside through the siphon pipe 20, And the water level inside the siphon pipe 20 is maintained at the same level as the water level of the lake 11.

4, when the water level of the lake 11 is increased due to heavy rain or flood, and the water level of the lake 11 becomes equal to the height of the waterway 13 of the lake 12, The water of the water surface (surface water) starts to flow over the water path 13 at this time. At this time, the low water of the water surface 11 is also filled in the siphon pipe 20 and is discharged through the other end of the siphon pipe 20 (In the present invention, the low-level water discharged through the siphon pipe 20 is mixed with the surface water discharged through the siphosphorus 13 and discharged to the outside, Thereby minimizing the impact on the surrounding water quality).

5, when the water level of the lake 11 further rises and the water level of the lake 11 becomes higher than the water level of the lake water 13 of the lake 12, Not only the amount of the overflow of the siphon pipe 13 is increased but also the water pressure corresponding to the water head difference between the water level of the sump 11 and the other end (discharge port) of the siphon pipe 20 is increased, (11) The amount of low-level water discharged through the lake is also increased.

6, when the water level of the lake 11 is gradually lowered and the water level of the lake 11 becomes equal to the height of the waterway 13 of the lake 12, (11) through the other end of the siphon pipe (20) by the water pressure equal to the water head difference between the water level of the sump pipe (11) and the other end of the siphon pipe (20) Is continuously performed.

7, when the water level of the sump 11 is further lowered and the water level of the sump 11 becomes equal to the height of the other end of the siphon pipe 20, (11) The outflow of the low-level water stops and the water level inside the siphon pipe 20 becomes equal to the water level of the lake 11 again. Thereafter, when the water level of the lake 11 is continuously lowered, the state returns to the state shown in Fig. 3 in advance.

10, the low-level water of the lake 11 discharged along the runway 13 of the dam 12 through the low-level water discharge device according to the present invention is discharged from the low- The contamination degree is reduced due to contact with sufficient oxygen through surface aeration in the process of dropping into the reservoir 14 formed on the lower surface of the dike 12 and the friction aeration and / or dike 12, thereby minimizing adverse effects on the surrounding water quality.

10, the low-level water of the lake 11 discharged through the other end of the siphon pipe 20 is first discharged from the other end of the siphon pipe 20 through the end of the siphon pipe 13, (See (1) in Fig. 10), friction with the slope surface 131 of the freeness 13 and spreading on the slope surface 131, thereby increasing the contact area with the air, (Ie, 'friction aeration'), and the low-level water with a high degree of pollution such as eutrophication due to anaerobic condition is contacted with sufficient oxygen through the above-mentioned friction aeration The pollution degree can be reduced.

10, the low-level water of the lake 11 which falls through the inclined plane 131 of the drainage path 13 stores the reservoir 14 formed at the dropping point, that is, (Refer to ② in FIG. 10) and the scattering due to the impact, sufficient contact with the outside air is made (this is referred to as 'sleep aeration'), so that the anaerobic The contamination degree of the low-layer water in a state of high pollution such as eutrophication due to the state can be further reduced by contact with sufficient oxygen again through the above-mentioned water aeration.

While the present invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, Should be interpreted as belonging to the scope.
