Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001]

The present invention relates to a lower water discharge system capable of preferentially discharging a lower water layer of water dewatered by a dam or a beam and more particularly to a lower water discharge system capable of selectively discharging a lower water layer And a method of operating the same.

Generally, a water intake installed in the lateral direction of a waterway such as a river or a river is used to store water, and a water gate is installed to control the water volume.

The water intake is provided by blocking a water source such as a river or a river, and the function of raising the water level and drawing water through the water channel is provided. In particular, a part of the beam is opened to form a waterway, and a water gate capable of being opened and closed is installed to control the water intake.

Specifically, the water intake can be classified into high-level information composed of concrete structures and movable beams automatically adjusting the water level.

The fixed viewer may form the entire section of the beam only by the gate. There are two types of upper and lower flow types, in which water flows consist of rubber tubes or steels, and the water flows upward from the upstream when the water level rises, . In addition, the opening / closing device of the water gate is a mechanical wire rope drum type and a hydraulic driving type.

However, since the bottom discharge type sluice gate is caught by the bottom of the sluice from the upper part to cause a problem in the operation of the machine, the upper sluice type sluice gate is mainly used.

In the case of the upper flood type watershed, the water level gradually increases due to the flow rate continuously flowing from the upstream while maintaining the set water level. At this time, the inflow water exceeding the set water level is discharged to the downstream side mostly at the upper layer located at the upper part of the watercourse, so the lower layer water and various sediments located at the lower part of the watercount accumulate. As a result, eutrophication and pollutants become prolonged, resulting in environmental problems such as water pollution.

Korean Patent No. 10-0799359 (a pneumatic movable beam capable of discharging a low-level water), in order to solve the above-mentioned problem of contamination of the lower layer water, discharges the submerged low-level water to the bottom of the fresh water, thereby preventing contamination of the fresh water, A foreign matter is prevented from accumulating on the bottom of the pneumatic movable beam.

However, such a configuration basically expands / contracts the air pressure of the rubber tube, thereby releasing the lower layer water when the rubber tube is conducted / rolled. Therefore, since the working fluid is compressible, the rubber tube can not be rapidly turned over / We can not implement it as we aimed at lower water discharge. In addition, there is a structural problem that it takes a long time to discharge the stored water because the lower layer water can be discharged only after almost all the domestic water that has been stored is lost.

Korean Patent No. 10-0799359 (published on January 30, 2008) Korean Patent No. 10-1074864 (issued October 19, 2011) Korean Registered Utility Model No. 20-0464944 (Bulletin published on January 24, 2013)

SUMMARY OF THE INVENTION Accordingly, it is a primary object of the present invention to provide a lower water discharge system capable of selectively discharging lower water having deteriorated water quality due to insufficient dissolved oxygen, thereby preventing water quality deterioration of the entire water.

A second object of the present invention is to provide a method of operating a lower water discharge system capable of selectively discharging the lower water of the water that has been dewatered by a dam or beam using the above-described lower water discharge system.

In order to accomplish the first object of the present invention, in one embodiment of the present invention, the movable beam installed in the water channel to restrict the movement of water, and the lower water layer formed by the movable beam at one end And the other end corresponding to the one end is disposed in a direction opposite to the fresh water and is disposed below the water surface of the fresh water, and a middle portion between the one end and the other end is coupled to the upper portion of the water receptacle, And a discharge pipe that is moved up and down of the lower layer water discharge system.

In order to attain the second object of the present invention, in one embodiment of the present invention, one end of the discharge pipe is disposed in the lower layer water desiccated by the movable beam installed with the gate, A discharge duct installation step of arranging the other end of the water outlet and connecting the central part of the discharge pipe located between the one end and the other end to the upper part of the water inlet; And an upper layer water blocking step of raising the hydrological gate so as to expose the upper layer water to the water surface so as to block the discharge of the upper layer water.

According to the present invention, it is possible to solve the problem that the existing moving beam can not discharge the lower layer water by installing the discharge pipe in the existing movable beam.

Further, since the present invention uses the discharge pipe using the siphon principle, no additional power is used to discharge the lower layer water of the fresh water formed by the movable beam.

Further, according to the present invention, the lower layer water of fresh water can be discharged even in the closed state of the water gate installed in the movable beam, so that only the lower layer water having a high dissolved oxygen content can be stored and only the lower layer water having low dissolved oxygen content can be discharged.

Further, in the present invention, since the lowest position of the dam or the reservoir can be arbitrarily selected at the position where the lower layer water is sucked, it is not possible to discharge only the lower layer at the front end of the beam, By moving one end of the flexible pipe, it is possible to discharge the lower layer water accumulated at a desired site.

1 and 2 are perspective views for explaining a lower layer water discharge system according to an embodiment of the present invention, and FIG. 3 is a perspective view for explaining a main body of the movable beam according to the present invention.

1 to 3, the lower layer water discharge system according to the present invention includes a movable beam 100 installed in a water channel, a dam, a reservoir or the like to restrict movement of water, And a discharge pipe (200) installed in the movable beam (100) so as to discharge the lower layer water.

Hereinafter, each component will be described in more detail with reference to the drawings.

The lower water discharge system according to the present invention includes the movable beam (100).

The movable beam 100 is installed in a water channel such as a river or a river, and a water gate 111 is installed so that a manager can selectively discharge fresh water. At this time, the movable beam 100 may be composed of the body part 120 and at least one water-receiving part 110 provided to the body part 120 according to the width and depth of the water channel, or may be composed of a single water- It is possible.

As shown in FIG. 3, the main body 120 is formed to have a length equal to the width of the water channel so that movement of the water moving along the water channel of the river or stream is restricted in a certain section, And has a height higher than the water surface by concrete or the like.

The water dispenser 110 is installed in a discharge port formed in the main body 120 so as to selectively discharge the water discharged through the movable beam 100. When the water is discharged, It may be formed in any configuration as long as the upper end thereof can move to a lower position.

As a specific aspect, the hydrologic portion according to the present invention can be configured to include the hydrologic gate 111, the chamber 112, and the driving means, as shown in Figs. 4 and 5.

The upper part of the water gate 111 is moved upward and downward to move the upper part out of the water surface so as to block the discharge of the fresh water through the discharge port or to move the upper part into the water surface to discharge the fresh water through the discharge port. As shown in FIG. For example, the water gate 111 may be formed to have a rectangular parallelepiped structure in which a hollow is formed and an open bottom is opened.

The chamber 112 is embedded in the bottom surface of the discharge port and is formed to have a longer length and a longer width than the gate 111 so that the gate 111 can enter into the chamber. For example, if the water gate 111 is formed to have a rectangular parallelepiped structure, the chamber 112 is preferably formed to have a rectangular parallelepiped structure. For example, the chamber 112 may be formed to have a rectangular parallelepiped structure in which a hollow is formed and an upper portion is opened.

The driving means is installed inside the chamber 112 and functions to raise and lower the water gate 111 according to a control signal transmitted from the outside.

The driving means according to the present invention includes a hydraulic pipe 113 connected to the hydraulic pressure application means provided outside the chamber 112 such as a hydraulic jack or a hydraulic pump and a hydraulic pipe 113 connected to the hydraulic pipe 113, And a hydraulic cylinder 114 installed between the hinge 112 and the hinge 111 to move the hinge 111 up and down. If necessary, a hydraulic hose 115 may be provided between the hydraulic pipe 113 and the hydraulic cylinder 114.

According to another aspect of the present invention, there is provided a driving apparatus for a vehicle, comprising: a communication module receiving a control signal transmitted by wire or wireless; a hydraulic pressure applying means for receiving a control signal through the communication module; And a hydraulic cylinder 114 connected to the hydraulic pipe 113 and installed between the chamber 112 and the water gate 111 to raise and lower the water gate 111 under the control of the hydraulic pressure applying means .

The upper end of the piston rod 116 of the hydraulic cylinder 114 is connected to the upper end of the inner side of the water gate 111 to perform a function of raising or lowering the water gate 111. In other words, as the hydraulic pressure is applied to or released from the hydraulic cylinder 114, the gate 111 rises as shown in FIG. 4 or the gate 111 descends as shown in FIG.

The lower water discharge system according to the present invention includes a discharge tube (200).

The discharge pipe 200 is configured to discharge the lower layer water of water to the outside of the water even if the movable beam 100 does not discharge the water directly. A part of which is coupled to the water gate 111 to enable the water gate 111 to be opened. At this time, it is preferable to use a flexible pipe having elasticity as the discharge pipe 200.

More specifically, the discharge pipe 200 is disposed in the lower water layer of the fresh water formed by the movable beam 100, and the other end corresponding to the one end is disposed in the opposite direction to the fresh water, do. In addition, the central portion located between the one end and the other end of the discharge pipe 200 is coupled to the upper portion of the water gate 111, and is moved up and down on the water surface according to the rising and falling of the water gate 111.

Even if both ends of the discharge pipe 200 are disposed at a position lower than the water surface of the fresh water, since the middle part, which is one of the parts connecting the both ends, is disposed at a position higher than the water surface of the fresh water, The flow of water is blocked. Accordingly, even if both ends of the discharge pipe 200 are positioned lower than the water surface, the water introduced into one end of the discharge pipe 200 can not be discharged to the outside of the fresh water through the other end of the discharge pipe 200.

However, since the discharge pipe 200 according to the present invention is installed in the movable beam rather than the high information, when the water gate 111 of the movable beam 100 descends to a position lower than the water surface as shown in FIG. 6, (230) is moved below the water surface together with the water gate (111) to be located lower than the water surface. Accordingly, in the discharge pipe 200, the lower layer water of the fresh water flowing into the one end 210 is discharged through the other end 220 due to the gravity effect applied to the water surface. In other words, the water introduced into the one end 210 of the discharge pipe is discharged through the other end 220 of the discharge pipe while pushing the air remaining in the middle portion 230 of the discharge pipe toward the other end 220 of the discharge pipe.

If necessary, a fixture 400 may be provided between the discharge pipe 200 and the water gate 111. The fixture 400 is configured to fix the center portion 230 of the discharge pipe to the upper portion of the water gate 111 so that the discharge pipe 200 is not separated from the water gate 111, Any fastener may be used as long as it is used.

For example, the fixture 400 may be a box-shaped block having front and rear open sides. At this time, the box-shaped block is fixed to the water gate 111 by its bottom surface being coupled to the upper surface of the water gate 111 through a screw or the like. And the outlet pipe 200 is coupled through the open front and rear faces of the box-shaped block.

In addition, the one end 110 of the discharge pipe needs a fixed fixture 500 to prevent the discharge pipe 200 from being swept by the flow of water without contacting the ground directly. The fixture 500 catches the discharge pipe 200 in contact with the ground to prevent the discharge pipe 200 from being swept by the water flow and at the same time separates the suction port of the discharge pipe 200 from the ground at a predetermined interval It is possible to prevent impurities in the bottom from mixing into the discharge pipe 200 and clogging the discharge pipe 200.

In one embodiment, the fixture 500 according to the present invention may be a fixed weight installed at one end 210 of the discharge pipe and fixing one end 210 of the discharge pipe to the ground. The fixed weft is configured to restrict the movement of the discharge tube 200 so that the one end 210 of the discharge tube 210 maintains the initial position even with an external force such as water flow, and may be formed in a block structure such as a rectangular parallelepiped. 2, one end of the fixed weight is connected to one end 210 of the discharge pipe, one or more water intake holes 510 through which water flows into the side surface, and the water intake hole 510 and the discharge pipe A moving path of water is formed between one end 210 of the water-

As another embodiment, a fixture (not shown) may be used as the fixture 500 according to the present invention between the discharge pipe 200 and the water gate 111. Such a cradle is configured to limit the movement of the discharge tube 200 so that one end 210 of the discharge tube and the other end 220 of the discharge tube maintain their initial positions even in the case of water flow or wind force. Includes two cradles.

The first cradle is installed between the end of the discharge pipe 210 disposed in the water despooled through the movable beam 100 and the side surface of the water gate 111, and may be composed of a plurality of first bars. At this time, the first rod may be coupled to the discharge tube 200 and the water gate 111 through screws or wires.

The second cradle is installed between the other end of the discharge pipe 220 disposed in the opposite direction of the water despooled through the movable beam 100 and the side surface of the water gate 111 and may be composed of a plurality of second bars . At this time, the second rod may be coupled to the discharge tube 200 and the water gate 111 through screws or wires.

The lower water discharge system according to the present invention may further include an air discharge unit.

The air discharge unit is installed in the discharge pipe 200 to smoothly remove the air remaining in the discharge pipe 200 moved below the water surface and includes the opening and closing unit 310 and the air valve 320, Valve 320 only.

Even if the central portion 230 of the discharge pipe is lowered below the water surface as the water gate 111 is lowered below the water surface, the air in the discharge pipe 200 can not be discharged to the outside of the discharge pipe 200, Problems that are not discharged can be prevented. In other words, even if the water flows into the other end 220 of the discharge pipe 220 before the air inside the discharge pipe 200 is completely discharged to the other end 220 of the discharge pipe 220 and the remaining air moves to the inside of the middle part 230, And the air inside the discharge pipe 200 is discharged to the outside of the discharge pipe 200 through the discharge pipe 320.

More specifically, the opening / closing part 310 is installed at the other end of the discharge pipe 200 so as to restrict the movement of water through the discharge pipe 200. At this time, the other end 220 of the discharge pipe 200 refers to the end of the discharge pipe 200 disposed outside the water that has been dumped by the movable beam 100 at both ends.

In one embodiment, the opening and closing part 310 according to the present invention may be configured as a tube plug for sealing the other end of the discharge tube 200 manually by an administrator.

As another embodiment, the opening and closing part 310 according to the present invention may include a motor that operates in accordance with a control signal transmitted from a remote location, and a motor that is shaft-coupled to the rotation shaft of the motor and opens and closes the other end 220 of the discharge pipe And a cover plate. At this time, the cover plate may be provided with a sealing portion formed of rubber, silicone, or the like on a surface contacting the other end 220 of the discharge tube. Such a sealing part provides a function of blocking water from being discharged through the other end 220 of the discharge pipe when the other end 220 of the discharge pipe is sealed by the cover plate.

The air valve 320 is configured to discharge the air remaining in the discharge pipe 200 before the discharge of the fresh water and to introduce the air to stop the discharge of the water being discharged. An air valve may be used. At this time, the air valve 320 is installed in the middle portion 230 of the discharge pipe contacting the upper portion of the water gate 111.

If the opening / closing part 310 can not be installed at the other end of the discharge pipe 200, it is preferable that the other end of the discharge pipe 200 is disposed below the water surface formed outside the movable pipe 100. This is to perform the discharge of the lower layer water using the siphon principle even if the opening / closing part 310 is not provided at the other end of the discharge pipe 200 of the present invention.

If necessary, the lower water discharge system according to the present invention may further include an air pipe 600 and a float switch 700.

The air pipe 600 provides a space in which the float switch is installed and is installed at an upper portion of the air valve 320 to communicate with the air valve 320 or at a central portion 230 of the discharge pipe to be connected to the discharge pipe 200, Respectively. The air pipe (600) is formed with a vent at a side thereof to provide a passage through which the air discharged from the air valve (320) and water are discharged into the fresh water.

The float switch 700 controls the operation of the air valve 320 by sensing the water flowing into the air valve 320. The float switch 700 generates a closing signal of the air valve 320 as the water contacts the float switch 700 Air valve 320, generates a rising signal of the movable beam 100, and transmits it to the driving means of the movable beam.

More specifically, the float switch 700 is installed inside the air pipe 600. At this time, it is preferable that the floater included in the float switch 700 and the air valve 320 are installed in the discharge pipe 200 in a direction perpendicular to the gravity direction.

Further, the floater of the float switch 700 is installed inside the air pipe 600 adjacent to the air valve 300 to sense that air is completely removed from the inside of the discharge pipe 200.

When the upper end of the float switch 700 is moved to a lower position than the water surface of the movable beam 100, the float switch 700 is installed inside the air pipe 600 so as to be disposed at a position lower than the water surface. . This is because if the float switch 700 is lower than the water surface, it is possible to detect that the water has flowed into the float switch 700 after the air has run out and the air is completely lost. That is, when the float switch 700 floats on the water, it can be determined that the discharge pipe 200 satisfies the condition of the siphon pipe.

8 is a flowchart for explaining a method of operating a lower water discharge system according to the present invention.

8, a method for operating a lower water discharge system according to the present invention includes a discharge pipe installation step (S100) for installing a discharge pipe (200) on a movable beam (100) An air discharge step S200 for lowering the upper part of the water level down to the water level and an upper water level blocking step S300 for blocking the discharge of the upper layer water by raising the water level door 111 so that the upper part of the water level door 111 is exposed above the water level do.

Specifically, in the step of installing the discharge pipe (S100), one end (210) of the discharge pipe is disposed in the lower layer water desnosed by the movable beam (100) provided with the water gate (111) And the middle portion 230 of the discharge pipe located between the one end 210 and the other end 220 is coupled to the upper portion of the water gate 111. [

The air discharging step S200 may include a discharge tube sealing process for sealing the other end 220 of the discharge tube with the opening and closing part 310 before the descending of the water gate for lowering the upper part of the water gate 111 down to the water surface, And an air valve opening process for opening the air valve 320 communicated with the central portion 230.

As described above, when the central portion of the discharge pipe 200 becomes lower than the water surface, the water is sucked into the one end 210 of the discharge pipe arranged in the lower water layer by the water pressure. At this time, the water flowing into the discharge pipe 200 starts to fill up from the other end 220 of the discharge pipe more than the middle part 230 of the discharge pipe due to the height difference, and the air inside the discharge pipe 200 gradually flows into the air valve 320, respectively.

9 is a flowchart for explaining another embodiment of a method of operating a lower water discharge system according to the present invention.

9, when the air remaining in the discharge pipe 200 is completely removed between the air discharging step S200 and the upper water blocking step S300, the air valve 320 is closed and the other end (S250) for controlling the opening and closing part (310) to discharge the lower layer water so that the lower layer water outlet (220) is opened.

In addition, in the upper layer water blocking step S300, the water gate 111 is raised so that the upper part of the water gate 111 is exposed above the water surface so that the discharge of the upper layer water is blocked. As a result, the discharge of the upper layer water through the water gate 111 is blocked, and only the lower layer water is discharged through the discharge pipe 200.

If necessary, the method of operating the lower water discharge system according to the present invention may further include an air valve opening step (S400) after the upper water barrier step.

The air valve opening step S400 is a step of opening the air valve 320 such that the air is introduced into the discharge pipe 200 through the air valve 320. The air introduced into the air valve 320 flows through the discharge pipe 200 to prevent the discharge of the lower layer water continuously. As a result, by controlling the air to flow into the discharge pipe 200, the discharge of the lower water through the discharge pipe 200 is naturally prevented.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit and scope of the invention as defined in the appended claims. It can be understood that it is possible.
