Description

[Background Art] [0002] Green algae prevention and sludge release system for upstream of dam

The present invention relates to a system for preventing the occurrence of green tides and discharging sedimented sludge by allowing stagnant water in the upper deep section to flow downstream using the siphon principle.

It is used to keep the water flow and to maintain and control a certain quantity of water. It functions to temporarily store the water flowing from the upstream. However, there is a problem that the soil, organic matter, and garbage that have flowed from the upper stream of the volcano are clogged and accumulated. As a result, the amount of dissolved oxygen decreases as the depth of the upstream part of the beam decreases. As the water becomes stagnant and green tide is generated, water pollution of rivers and streams and destruction of environmental ecosystem are caused.

Conventionally, in order to solve such a problem, there have been derived "underwater beam with guide tube (Korean Patent Laid-open Publication No. 1994-0018527)" and "underwater accumulation in sediment (Korean public utility model 1995-0033385)". However, in the case of the above-mentioned "underwater pipe with induction pipe, " there is a problem in that sediment accumulates between the induction pipe and the induction pipe and is not discharged to the downstream, and the induction pipe is blocked by the sediment, In this case, the sediment is discharged through the hole. However, there is a problem that the quantity of water, which is the original function of the underwater ship, can not be maintained properly.

On the other hand, a siphon device that lifts the liquid at a high place and moves it to a low place without tilting or moving the container is widely used in real life. "Automatic discharge system of inner ash deposits (Korean Patent No. 10-0424282)" is intended to discharge sediments in the lower part of the underwater in the upstream side of the stream to the downstream side using the siphon principle. However, the siphon principle does not mean that low water can be moved to a high place, but even if there is a rather high jaw, it is possible to cross the jaw if the final destination is lower than the original position. Taking the water from low to high without energizing creates a new potential energy, which is against the first law of thermodynamics. [Refer to Fig. 1] below, which corresponds to Fig. 4 of the "automatic aspiration system of the internal ash deposits (Korean Patent No. 10-0424282)", is an idea that can not be implemented in violation of the first law of thermodynamics .

[Reference Figure 1]

 Further, in order to operate the siphon, the pipe through which the water moves must be filled with the liquid. The above-mentioned " automatic discharge system of the inner ash deposits (Korean Patent No. 10-0424282) " It is difficult to consider the case where the drainage passage 16 formed between the underwater basins 6a, 6b, 6c, and 6d and the underwater beam 3 is filled with water, so that the siphon principle can not be implemented.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

As shown in Fig. 1, the present invention is characterized in that: " beam 110 installed to divide upstream and downstream across a river; An inflow portion 120 formed below the upstream floor at a lower portion of the downstream side of the beam; The inlet port 131 is disposed at the uppermost floor of the river and the outlet port 132 is disposed at the inlet port 120. The flow pipe which is routed over the beam 110 to reach the recessed portion 120 130); And an on-off valve 135 coupled to the flow pipe; , The water in the uppermost stream portion of the stream is sucked into the flow pipe inlet port (131) by the siphon principle and is discharged to the discharge port (132). .

The present invention is provided in a beam 110 installed in a river such as a river or a river. According to the present invention, by discharging the water in the deep part of the stream to the siphon principle, it induces the circulation of the water between the surface layer and the deep part of the river, and the water in the deep part It is intended to protect the ecosystem by increasing the dissolved oxygen concentration and to obtain the effect of cleaning and dredging by discharging sediments accumulated on the bottom of the beam along with the water of the deep part to the downstream side.

The siphon principle is useful when moving water from a high place to a low place without powering it. Therefore, to move water (deep water) upstream of the beam on the basis of beam, the downstream floor must be lower than the upstream floor. However, since the bottom of the stream is formed of a continuous surface, the lower portion of the lower surface of the beam 110 is formed with the lower portion 120 lower than the upper floor.

The inlet port 131 is disposed at the uppermost floor of the stream and the outlet port 132 is disposed at the inlet port 120. The flow pipe 130 passing over the inlet port 120 allows the water Can be moved downstream. By the formation of the recess 120 and the arrangement of the flow pipe 130, the oxygen vacancies on the upstream floor are discharged downstream, and water circulation is performed, so that the amount of dissolved oxygen is increased in the upper deep portion to protect the ecosystem . In addition, the increase of dissolved oxygen in the upper deep part suppresses the elution of nutrients (anaerobic decomposition inhibition) and consequently the occurrence of green algae is suppressed.

However, by connecting the opening and closing valve 135 to the flow pipe 130 in order to prevent the water level control function, which is the original function of the beam, from being lost, the water movement can be controlled and the water level in the upstream can be adjusted.

Meanwhile, as shown in FIG. 2, a plurality of branch pipes 140 can be coupled to the flow pipe 130. A suction port 141 is formed at the distal end of the branch pipe 140. The water in the upper portion of the stream is sucked into the suction port 131 of the flow pipe 130 by the siphon principle and sucked into the branch pipe suction port 141 and discharged to the discharge port 132 of the flow pipe 130 do. Further, another branch pipe (hereinafter, referred to as 'auxiliary branch pipe') is further coupled to the branch pipe 140 as necessary, and water is sucked into the suction pipe 142 of the branch pipe, ). ≪ / RTI > By connecting the branch pipe 140 to the flow pipe 130, the water at the bottom of the upstream river can be sucked evenly, and the effect of cleaning and dredging can be obtained through suction and discharge of sediment. 2, the depressed portion 120 may be formed so that the periphery of a point where the discharge port 132 of the flow pipe 130 faces is recessed from the bottom surface.

The filter 150 as shown in FIG. 3 can be coupled to the inlet 131, 141 of the flow pipe 130 and the branch pipe 140, respectively. By controlling the mesh size of the screen 150, a relatively large object such as a piece of stone or wood can be prevented from clogging the pipe and the sludge such as mud can be sucked-discharged.

The inlet ports 131 and 141 of the flow pipe 130 and the branch pipe 140 are bent in the upward direction as shown in Fig. 3 to induce vortex generation around the suction port, Only light sludge can be configured to be inhaled with water.

Also, though not separately shown, by bending the suction ports 131 and 141 of the flow pipe 130 and the branch pipe 140 downward, induction of vapors around the suction port and suction / discharge of the sediment can be performed more efficiently . However, in this case, since the flow path 130 or the branch pipe 140 may be clogged, it is possible to prevent a relatively large object from being clogged with the pipe due to the combination of the filtering wire 150 described above.

The inlet ports 131 and 141 of the flow pipe 130 and the branch pipe 140 may be bent upward or downward according to the state of the upstream floor of the beam 110 as described above.

4, the screw blades 160 coupled in a spiral manner along the inner circumferential surfaces of the inlet ports 131 and 141 of the flow pipe 130 and the branch pipe 140 are coupled to each other, And generate a vortex around the suction port. A flow of water rotates around the suction ports 131 and 141 as a result of the flow of water rotating around the screw blades 160 as the water is sucked, thereby generating a local flow at the upper deep portion, Of the sediment in the water.

Such a screw blade 160 can be constructed in the same manner as the screw nozzle disclosed in the registered patent 10-1168663 "Water tank equipped with screw nozzle ". However, the screw nozzle 160 differs from the screw nozzle 160 in that the screw nozzle 160 generates a vortex while sucking water if the screw nozzle 160 functions to generate a vortex while spraying water.

5, the water pump 170 is coupled to the flow pipe 130 so that when the siphon operation is not performed because the water level in the upstream is low, the water pump 170 is actuated, Can be configured to operate. In other words, the water flow can be given to the stagnant water in the wet season to prevent the water flow, the flow rate can be controlled by the on-off valve 135, and the operation of the water feed pump 170 can be stopped when the siphon operation is progressed.

The open / close valve 135 may be installed in the upstream section and the downstream section of the flow pipe 130, as shown in FIG. 6, instead of the feed pump 170, It is possible to solve the problem that air is introduced into the flow pipe 130 or the siphon operation can not be performed because the water level in the upstream side is low due to the connection of the water pipe 180. [

The supplementary water pipe 180 is branched from the open / close valve 135 of the flow pipe 130 and opens to the atmosphere. The supplementary water pipe 180 is connected to an injection valve 181. As shown in FIG. 6, the funnel-type replenishing water injecting unit 182 extending upward can be coupled to the upper end of the replenishing water pipe 180 to improve the convenience and efficiency of the replenishing water injecting operation.

In this configuration, the siphon action is generated by the non-dynamic force, and both of the on-off valve 135 mounted on the upstream section and the downstream section of the flow pipe 130 are closed, the injection valve 181 is opened, (The air in the flow pipe 130 at this time is discharged through the makeup water pipe 180). After the injection valve 181 is closed, the opening / closing valve 135 is fully opened, Let it happen.

Further, as shown in Fig. 7, the siphon action can be induced by the power. To this end, the opening / closing valve 135 is installed in the upstream section and the downstream section of the flow pipe 130, respectively, and the replenishing water pipe 180 is coupled between the opening and closing valves of the flow pipe 130. same. However, the air pipe 190 must be coupled to the flow pipe 130 and the supplementary water pipe 180 must extend up to the upstream of the stream and the supplementary water pump 185 ) Must be combined. The air tube 190 is also branched from the open / close valve 135 of the flow tube 130 to be open to the air. The air tube 190 is connected to an air discharge valve 195.

With this configuration, both of the opening / closing valve 135 mounted on the upstream section and the downstream section of the flow pipe 130 are closed, and the air discharge valve 195 is opened. (The air in the flow pipe 130 is discharged through the air pipe 190), and then the air discharge valve 195 is closed , The opening / closing valve (135) are all opened to cause the siphon action to occur with no force.

8, the hydroelectric power generator 200 is coupled to the downstream section of the flow pipe 130 to generate electric power by water falling along the flow pipe 130 have.
