Description

Hydrogate App {Floodgate appartus}

The present invention relates to a valve installed in a hydrological facility, and more particularly, to prevent inundation damage caused by flooding or sea level rise in advance, and to promote stable drainage through a drainage passage, through the miniaturization of a hydrological gate and a miniaturization of a hydrological facility structure. It relates to a hydrological device for reducing the cost.

In general, water gates for various uses are installed at the end of waterways such as rivers and rivers in the direction of waterways and rivers to provide smooth drainage to the external water side of the internal water, and to serve as a dimension to block the reverse flow of the internal water. It has three functions: water drainage, which uses water resources, and forced drainage of forced water drainage when the external water level rises.

In regard to the dimensional problem of the conventional hydrological gate, the ditches are installed in the waterways of rivers, river banks, and embankments, and are normally opened to drain the upstream internal water to the downstream external water. If the water level rises above a certain level, the water gate is first lowered to close the waterway, preventing the inflow of water into the domestic water. At this time, if the water gate is closed, the inflow of external water can be blocked, but the internal water is not naturally drained, so if the rainfall persists, the water level will rise, and low-level houses or farmland without a separate drainage system will cause flood damage due to flooding. There was a problem.

Therefore, drainage pumping station or rainwater pumping station is installed to prevent flooding due to flooding of low-lying houses or farmland, and it is necessary to purchase drainage pumping and reservoir site, civil engineering and hydrological construction work for drainage pumping station, drainage pump and electric facility materials cost. Due to enormous budgetary demands such as overhead, overhead cranes, equipment cost, and mechanical and electrical construction costs, there was a problem in that the drainage pumping station could not be constructed in response to the entire demand.

In particular, there are no spaces to install drainage pumping stations in low-lying areas around rivers or cities connected to large rivers, and central governments and local governments are unable to finalize their projects due to landowners' high demand for land compensation. Construction of drainage pumping stations has not been realized in response to demand.

Therefore, when an annual typhoon or a recent frequent guerrilla torrential rain or rainy season occurs, the external water level suddenly rises and the domestic water level rises at the same time. .

In order to solve the problems of the dimensions and forced drainage, the water gate in which an opening is formed in a square plate-shaped body of water and the pump is integrated into this opening is Korea Utility Model Registration No. 20-0361664 (backflow prevention valve and submersible pump are provided. Han hydrology), Republic of Korea Patent Registration No. 10-0497044 (Pump integrated hydrology and its driving method), Republic of Korea Patent Application Publication No. 10-2005-0104220 (Pump integrated hydrology), Republic of Korea Patent Registration No. 10 -0563369 (drainage for drainage), Korea Utility Model Registration No. 20-0390498 (drainage of hydrologic) and Korea Utility Model Registration No. 20-0403219 (drainage of hydrologic).

However, the above-mentioned water gate integrating the valve and the pump causes a problem that water leakage occurs due to the uniformity or vibration in the water gate due to the vibration caused by the operation of the pump, and thus requires countermeasures. And manufacturing costs are high, there is a problem that the installation and maintenance costs are set high, such as to repair the corresponding parts to separate the entire hydrology in case of failure, and to replace the entire hydrology when replacing.

Embodiments of the present invention are to use the roller gate and the pump unit in a separate state, respectively, and to achieve the stable use of the roller gate and the convenience of installation, maintenance and reduction of the corresponding unit cost.

According to an aspect of the invention, the roller gate is installed to be opened and closed on the drainage path formed in the hydrological equipment; A pump unit spaced apart from the roller gate and installed independently and provided to forcibly drain the domestic water introduced through the drainage path to the outside of the hydrological facility; A bypass flow path formed between the drain path and the pump unit and provided such that the internal water introduced through the drain path is discharged to the outside through the pump unit without passing through the roller gate; An auxiliary gate provided at a front end position of the roller gate, the auxiliary gate being opened and closed in cooperation with the roller gate; A driving unit providing a driving force necessary for raising and lowering the roller gate; And a control unit configured to control the operation state of the pump unit and the driving unit by receiving the sleep information sensed by the sensing sensor installed in the drainage passage, wherein the control unit discharges the discharge port when the reverse flow of the sea water occurs through the discharge port due to sea level rise. The pump unit maintains the closed state of the pump unit so that the seawater introduced through the bypass flows back to the auxiliary gate and controls the auxiliary gate to be opened only when the pump unit is turned on. It characterized in that the control to discharge the domestic water introduced into the drain to the outlet.

Referring to FIG. 4, the controller 600 provides information on the current level of the drainage passage 10 through the sensor 4 installed in the drainage passage 10 for the operation of the driving unit 500 and the pump unit 200. It receives the input, and controls the operating state of the drive unit 500 and the pump unit 200 based on the input information.

For example, the controller 600 controls the pump unit 200 to be operated solely in a state where the operation of the driving unit 500 is stopped when the water level of the drain 10 is low, and the water level of the drain 10 is controlled. When the high water level is controlled so that both the driving unit 500 and the pump unit 200 is operated. The detection sensor 4 includes a first detection sensor 4a provided on the right side of the roller gate 100 and a second detection sensor 4b installed close to the position of the left outlet 11 on the basis of the drawing. The first detection sensor 4a detects sleep information of the drainage path 10, and the second detection sensor 4b detects sleep information of the outlet 11.

The use state of the hydrological device according to an embodiment of the present invention configured as described above will be described with reference to the drawings.

5 to 6, the control unit 600 receives the sleep information of the drainage channel 10 detected by the first detection sensor 4a and determines the current sleep state of the drainage channel 10. For example, when the water level of the drainage path 10 is lower than the low water level or the dangerous water level, the control signal is transmitted only to the pump unit 200 without transmitting the control signal to the driving unit 500. For reference, when the water level of the drainage channel is in a low water level state, the roller gate 100 is kept in a closed state, and the internal water flows into the front end of the pump unit 200 through the bypass flow path 300 is maintained and the auxiliary gate ( 400 is kept open.

The controller 600 may control the operation state of the pump unit 200 differently according to the water level of the drain 10, and when the water level of the drain 10 is less than or equal to the dangerous level, transmits a control signal to the submersible pump.

The pump unit 200 has the gate 202 rotated to the outside by the internal water discharged while the submersible pump is driven, and the internal water introduced into the drainage path 10 is the bypass flow path 300 and the pump as shown by the arrow. It is discharged outward through the outlet 11 via the unit 200.

The controller 600 analyzes the sleep information introduced through the first sensor 4a after a predetermined time elapses to determine whether the pump unit 200 is stopped or continuously operated, and the water level of the drain 10 When it is lowered, the operation of the pump unit 200 is stopped after a predetermined time elapses.

If the controller 600 receives the water level information input through the first detection sensor 4a and determines that the water level of the drain 10 is not reduced, the controller 600 transmits a control signal to the driving unit 500 to provide the roller gate ( Lift 100).

When the roller gate 100 is raised, the weight (2) is lifted upward, the tension of the wire 410 is partially released and the auxiliary gate 400, which was kept open, is closed.

Therefore, a large amount of domestic water introduced into the drain 10 is discharged to the discharge port 11 through a space opened below the elevated roller gate 100 as shown by the arrow, and after a predetermined time has elapsed When the water level of 10 drops, the roller gate 100 returns to its original position, and the auxiliary gate 400 switches to the open state.

Referring to FIG. 7, when precipitation increases due to a rainy season or a typhoon, a large amount of domestic water flows through the drainage path 10. If the sluice device 1 is installed adjacent to the sea, the backwater of the seawater is made through the outlet 11 by rising sea level, and the left side water level of the roller gate 100 is relatively higher than the right water level, thereby causing flood damage. Since the controller 600 determines the water level information input through the first to second detection sensors 4a and 4b and the roller gate 100 maintains the closed state according to the determination result, the pump unit The control signal 200 is transmitted to operate.

The pump unit 200 is maintained in a closed state so that the seawater introduced through the outlet 11 before the operation is not moved to the auxiliary gate 400 through the bypass flow path 300, and the pump unit 200 is operated. Only when the gate 202 is rotated to the outside, the domestic water flowing into the drain 10 is discharged through the outlet 11 via the bypass passage 300 as shown by the arrow.

Therefore, even when the sea level rises, the stable hydrological device can be operated. Through this, the water level of the drainage passage 10 can be kept constant. It is possible to reduce the fire cost, and do not need to maintain the entire floodgate in case of failure and maintenance, and to reduce the convenience of maintenance, installation and maintenance cost by replacing and maintaining only the relevant parts of the pump unit if necessary. .

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 of the invention as set forth in the appended claims. The present invention can be variously modified and changed by those skilled in the art, and it is also within the scope of the present invention.
