The present invention relates to storm drainage of the combined sewer system, and more particularly, to a storm drain control device that is capable of controlling the amount of sewage collected from storm drains to the drain pipe line according to the amount of sewage flowing into storm drains.

In general, sewage or wastewater or rainwater generated in homes and factories is collected by a drainage facility through an indoor pipe as shown in FIG. 1 and connected to a combined public sewer (10), and the contaminated sewage (10) is (20) is installed between the tea house (30) is a certain amount or more during the rainfall is discharged to the river, etc., the tea house (30) is connected to the sewage end treatment plant (40) sewage flowed in from the storm water chamber (20) The wastewater is sent to the sewage treatment plant 40, and the sewage treated in the sewage treatment plant 40 is discharged to the stream.

Here, the rainwater soil refers to a facility for collecting certain amount of sewage in rainy weather at a confluence type sewer and transporting it to a sewage treatment plant and discharging the remaining sewage into water bodies such as rivers. In other words, in the combined sewer, all the sewage is collected in Cheongcheon, but when a large amount of rainwater flows in, such as rainy weather, a large amount of rainwater is collected and sent to the sewage treatment plant, which increases the construction and maintenance costs of the treatment plant. It is uneconomical due to large diameter conduit. Therefore, if the amount of sewage planned for each discharge area reaches the planned amount of sewage (3 times the maximum maximum amount of time) during rainy weather, more rainwater is required to be installed so that it can flow to the discharge stream. Such a structure is called storm silt.

The stormwater inlet is connected to the sewage inlet and the rainwater inlet, and at one side of the bottom, a connection pipe is connected to the sewage pipe to the collecting pipe, and a monthly wearware is installed at the bottom of the sewage, and the sewage corresponding to the amount of tea collection The rainwater collected after collecting through the ware and entering through the conduit through the connecting pipe and overflowing the overflowware is immediately discharged to the river.

By the way, the conventional rainwater toss is to install an orifice in the connection pipe for ease of maintenance, this is a problem that the connection pipe is often occluded and cause an overflow accident.

That is, in the case of the conventional structure, the connection pipe is generally applied to 200 mm or more in consideration of maintenance, such as prevention of occlusion, but in most storm soils, the orifice diameter of several tens of mm is required. According to this structure, a hole for an orifice of several tens of millimeters is formed and provided in the connecting pipe.

Accordingly, when a solid or similar solid orifice, such as an empty can or a PET bottle, is introduced in the related art, an orifice is occluded, and even in Cheongcheon, sewage accidents that are discharged into the river beyond the overflowware are not allowed to flow into sewage pipes. Get up.

In order to solve this problem, a screen or the like is installed in the front end of the orifice in the related art, but requires frequent maintenance.

In addition, as shown in FIG. 7, the sewage flowing into rainwater silsoil has high water quality at the beginning of rainfall and then goes to the middle of the rainfall, and the water quality decreases and the amount of inflow sewage increases. Therefore, in terms of water conservation of rivers, it is necessary to collect as much of the initial sewage as possible and to collect less after mid-rainfall.

However, the conventional collection structure through the orifice collects a small amount when the high concentration sewage occurs at the beginning of the rainfall, and collects a large amount when the rainfall level is increased due to the continuous rainfall, so that the collection flow rate and the pollution load are not proportional. There is some irrationality.

Accordingly, the present invention has been made to solve the above-mentioned conventional problems, the object is to provide an excellent soil chamber flow control device that can prevent the occlusion accident.

In addition, the present invention is to control the amount of sewage in accordance with the concentration of sewage with the inflow of sewage to collect as much as possible early sewage high rainfall sewage and low sewage sewage in the latter half of the rainfall provides a stormwater flow control device that can collect a small amount There is another purpose.

In addition, the present invention is another object of the present invention to provide a rainwater tosoil flow control device that is able to collect only the planned sewage amount by adjusting the amount of tea according to the rainwater flowing in the rain.

In order to achieve the object as described above, the present invention is rotatably installed in the width direction in the upper rainwater chamber, and the gate to selectively open and close the rainwater soil, and connected to the upper end at a predetermined angle with the gate and the width of the rainstorm soil And a water level sensing plate arranged in a direction to rotate the gate in an open state by its own weight.

Here, an opening through which sewage flows may be further formed at a lower end of the gate.

Accordingly, as the level of sewage flowed into rainwater silos increases, the water level sensing plate lowered by its own weight is rotated by the sewage, and the gate connected to the water level sensing plate is rotated to close the rainwater silos and the sewage is formed on the gate. It is only collected through the opening so that only the desired amount can be planned.

In addition, the opening is preferably formed to a size capable of collecting three times the maximum amount of time sewage, which is the planned sewage during rain.

The present invention may further include an angle adjusting means for adjusting the angle between the gate and the water level sensing plate.

In addition, the present invention may further include a weight adjusting means for adjusting the rotation moment of the water level sensing plate.

In addition, the present invention may be further installed between the gate and rainwater tosoil for adjusting the opening and closing strength of the gate.

In addition, the present invention may further include a confirmation means connected to the gate to detect the degree of gate rotation to determine the degree of opening of the rainwater tossile.

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

1 is a schematic view showing a general sewage system, Figure 2 is a schematic side view showing the configuration of the stormwater flow control apparatus according to an embodiment of the present invention, Figure 3 is a rainwater according to an embodiment of the present invention It is a schematic front view which shows the chamber chamber flow control apparatus.

According to the above drawings, the control device according to the present embodiment is installed in the upper rainwater chamber 20, the installation frame 50 is fixed in the width direction, and the installation frame 50 is rotatably installed in the rainwater soil ( 20 is disposed in the width direction to selectively open and close the rainwater toil chamber 20, and at the lower end thereof, a gate 51 having an opening 52 through which the sewage flows out, and rotatably installed at the lower end of the installation frame 50. The water level sensing plate 54, which is disposed in the width direction in the width direction and is pushed and rotated by the sewage, is installed between the gate 51 and the water level sensing plate 54, and the gate 51 and the water level sensing plate 54. Is installed on one side of the angle adjusting means and the water level sensing plate 54 to maintain a constant angle, and is connected to the weight adjusting means and the gate 51 for adjusting the rotation moment of the water level sensing plate 54. Located outside rainwater chamber 20, gate 51 times The opening degree of the solid tosyl 20 according to the degree include detection means to determine the degree.

Wherein the installation frame 50 is fixed to the inner top of the rainwater chamber 20, a structure capable of supporting the gate 51 and the water level sensing plate 54 is installed via the rotary shaft 53 at the lower end It does not specifically limit in surface mounting structure.

In addition, the gate 51 is a plate structure rotatably installed on the lower end of the installation frame 50 via the rotation shaft 53, as shown in FIG. ) Is formed so that the sewage flowing into the stormwater chamber 20 can flow through the opening 52 while the gate 51 is closed.

In addition, since the gate 51 is positioned horizontally on the upper urethane chamber 20, both side ends of the gate 51 form a straight line shape.

Therefore, when the gate 51 is rotated in a vertical state to close the rainwater tosoil 20, an arc-shaped gap is generated between both side ends of the gate 51 and the inner circumferential surface of the rainwater tosoil 20. In the blocking plate 55 is further installed on both inner circumferential surface of the rainwater chamber 20 in order to prevent the occurrence of the gap in the size corresponding to the gap.

Accordingly, when the gate 51 is rotated in a vertical state to the stormwater chamber 20 to close the stormwater chamber 20, the stormwater chamber 20 is closed by the gate 51 and the blocking plate 55, and the stormwater chamber is closed. Sewage introduced into the 20 can be collected only through the opening 52 formed in the gate 51.

Here, the opening 52 is not limited in form or structure except that the opening 52 should be formed in a size capable of collecting three times the maximum amount of time sewage that is the planned sewage during rain.

Meanwhile, the water level sensing plate 54 is a plate structure rotatably installed on the installation frame 50 via the rotation shaft 53, and maintains a predetermined angle with the gate 51 through the angle adjusting means. Installed in one state.

The water level sensing plate 54 is preferably disposed in the width direction in the rainwater soil chamber 20 so as to be pushed out by the flow rate of the sewage flow into the rainwater soil chamber 20 to secure the maximum area in contact with the sewage.

In addition, the water level sensing plate 54 is not particularly limited in form, and has a structure that is heavier than the gate 51 in load, and the gate 51 connected through an angle adjusting means is the water level sensing plate 54. It is possible to maintain the open state by).

That is, the gate 51 and the water level sensing plate 54 are connected to the rotation axis 53 by the angle adjusting means is connected. Therefore, since the level of the water level sensing plate 54 is heavier than the gate 51, the water level sensing plate 54 can be lowered and the gate 51 can be lifted up and opened.

Here, the lower end of the gate 51 is preferably formed in an arc shape in order to avoid interference with the inner upper end of the rainwater chamber 20 when lifted up.

On the other hand, the angle adjusting means is for adjusting the operation start level of the gate 51, the screw shaft 56 is provided on the front of the gate 51 and the water level sensing plate 54, respectively, opposite to both ends A female threaded hole in a direction is formed to include a turnbuckle 57 to which the respective screw shafts 56 are fastened.

Accordingly, when the turnbuckle 57 is rotated in one direction, the length of the screw shaft 56 is tightened or released, thereby adjusting the angle of the gate 51 and the water level sensing plate 54.

In addition, the weight adjusting means is for adjusting the sensitivity of the water level sensing plate 54 when the operation level of the gate 51 is started, and is installed in a vertical direction on the front of the water level sensing plate 54 and on the surface. The guide rod 58 is a threaded process, and the weight 59 is fastened to the male screw of the guide rod 58.

Accordingly, as the weight 59 is rotated by lowering the weight 59 along the guide rod 58 by changing the weight 59, the center of gravity of the water level sensing plate 54 is changed, so that the water level sensing plate 54 is formed around the rotation shaft 53. It can change the rotation moment of).

Thus, the gate 51 can be opened and closed at the desired level through the angle adjusting means and the weight adjusting means. That is, by adjusting the angle of the gate 51 and the water level sensing plate 54 to adjust the position of the tip of the gate 51, for example, by rotating the turnbuckle 57 to tighten the screw shaft 56 and the gate 51 As the angle between the water level sensing plate 54 decreases, the position of the tip of the gate 51 is lowered. On the contrary, if the screw shaft 56 is released by rotating the turnbuckle 57, the gate 51 and the water level sensing plate ( As the angle between 54 increases, the tip position of the gate 51 becomes high.

In addition, when the weight 59 is moved along the guide rod 58 installed in the water level sensing plate 54, the rotation moment of the water level sensing plate 54 is changed to adjust the operation sensitivity of the water level sensing plate 54. For example, when the weight 59 is lowered along the guide rod 58 to the lower end of the water level sensing plate 54, the rotational moment of the water level sensing plate 54 becomes larger and the operation level of the gate 51 becomes higher. will be.

In addition, the gate 51 has a structure in which the opening degree is controlled by the elastic force of the spring installed between the rainwater soil chamber 20 and the gate 51 in addition to the water level detecting unit and the weight 59.

To this end, as shown in FIG. 2, a wire 60 is connected to the gate 51, and the wire 60 extends through the installation frame 50 to the outside of the rainwater tortilla 20 to mediate the spring 61. The structure is connected to. Accordingly, when the wire 60 is pulled in accordance with the rotation of the gate 51, the spring 61 is compressed to control the degree of rotation of the gate 51.

Referring to Figure 4 in more detail with respect to the installation structure of the spring 61 and the wire 60, the spring 61 is fitted to the wire 60, the housing 62 separately installed outside the rainwater chamber 20 A nut 64 constituting the sheet of spring 61 is fastened to the tip of the wire 60 so as to be caught by the tip of the spring 61.

Therefore, when the wire 60 is pulled, the spring 61 is elastically compressed between the housing 62 and the nut 64 to apply a rotational pressure to the gate 51, and if necessary, the nut 64 is connected to the wire 60. It is possible to adjust the tension of the spring 61 by rotating about.

Reference numeral 63, which is not described in FIG. 4, is a sheath surrounding the wire.

On the other hand, the checking means is installed in the housing 62, as shown in Figure 4 is connected to the front end of the wire 60, the indicator for displaying the opening amount of the gate 51 according to the degree of pulling the wire 60 It is made of 65.

Hereinafter, the operation of the present invention will be described with reference to FIG. Reference numerals not shown in the following description refer to reference numerals described above.

When the amount of sewage flowing into the rainwater silos 20 in Cheongcheon is small, the sewage is collected into the collecting pipe 30 as it is while the gate 51 is completely open.

That is, when the amount of sewage is small, since the sewage flowing along the bottom of the rainwater sediment chamber 20 does not reach the water level detecting plate 54, the water level detecting plate 54 is kept down by its own weight. Thus, the gate 51 is rotated in a horizontal state to completely open the stormwater chamber 20.

This is because the gate 51 and the water level sensing plate 54 are connected to each other via the screw shaft 56 and the turnbuckle 57, and the water level sensing plate 54 which is heavier than the gate 51 has its own weight. By rotating around the axis of rotation 53 with the upper installation frame 50 to form a vertical state, the gate 51 is pushed by the screw shaft 56 and the turnbuckle 57 is rotated in a horizontal state Will be.

Accordingly, all of the sewage of Cheongcheon-si can be collected by the tea house 30.

In this state, when the rainfall starts and the sewage flows into the storm sediment 20, the level in the storm sediment 20 rises, so that the water level detecting plate 54 detects the level gradually increasing to close the gate 51. do.

That is, when the rising sewage reaches the bottom of the water level detecting plate 54 and the water level is gradually increased further, the water level detecting plate 54 is gradually locked to the sewage and is pushed by the flow rate of the sewage, and the installation frame 50 It starts to rotate about the rotation axis 53 of the ().

Here, the water level sensing plate 54 is rotated down by the load and the rotational moment generated by the weight 59 and the gate 51 of the spring 61 connected by the wire 60. The water level sensing plate 54 starts to rotate when the flow rate of the sewage is pulled upward by the elastic force to overcome the elastic force of the spring 61 of the rotation moment of the water level sensing plate 54.

As the water level sensing plate 54 is rotated, the gate 51 connected to the water level sensing plate 54 via the turnbuckle 57 and the screw shaft 56 rotates toward the water surface and gradually descends. The tip of the gate 51 comes into contact with the sewer surface.

When the gate 51 contacts the water surface and is submerged in the sewage, the contact area between the sewage and the gate 51 increases, and the gate 51 rotates vertically by the flow rate to close the stormwater chamber 20 and close the water pressure. As a result, the gate 51 remains closed.

As such, when the gate 51 closes the storm drain chamber 20, the storm storm chamber 20 is closed by the blocking plate 55 provided between the gate 51, the gate 51 side end, and the storm storm chamber 20. And only the sewage flows through the openings 52 formed under the gate 51.

Therefore, only the planned amount of tea collected through the opening 52 may be collected in the tea pipe.

Here, the opening and closing amount of the gate 51 can be confirmed through the indicator 65 installed outside the rainwater chamber 20. As the gate 51 is rotated, the wire 60 is pulled and the tip of the wire 60 is pulled out. The indicator 65 installed at is to move the needle in proportion to the pulling of the wire 60 to display the current degree of opening of the gate 51.

On the other hand, when the water level is gradually lowered after the end of the rainfall, the water pressure applied to the gate 51 is also gradually lowered and the rotation moment of the water level sensing plate 54 and the spring caught on the gate 51 than the water pressure applied to the gate 51. When the elastic return force of 61 is a large point, the gate 51 is gradually rotated and lifted to open the rainwater soil chamber 20.

And when the sewage is lowered below a certain level, the gate 51 is completely rotated to open the rainwater soil chamber 20 100% and the sewage is collected entirely.

FIG. 6 is a graph comparing the amount of sewage collection in the storm drain chamber 20 in which the conventional storm drain chamber 20 and the flow control apparatus according to the present embodiment are installed. As shown in the graph, the initial rainfall in the present embodiment There is more sewage than the stormwater chamber 20 installed in the conventional orifice, and after the middle of the rain, the storm pipe 20 according to the present embodiment, whereas the conventional pipe structure without the orifice is introduced into the sewage than the planned collection volume It can be seen that only the planned amount is drawn.

That is, the conventional stormwater chamber 20 is operated in an irrational collection method in which high concentration sewage is collected less when the initial rainfall level is low, and a large amount is collected when the sewage concentration is lowered due to high water level. In other words, sewage is collected irrespective of the pollutant load, which seriously adversely affects the quality of the river, and does not make the most of the limited drainage channel capacity. On the other hand, in the rainwater soil chamber 20 in which the control device is installed, since the gate 51 is normally open at all times, there is no fear of blockage due to coarse suspended matter, and all the initial water having high water quality is collected and only the flow rate to be collected in rainy weather. It will be possible to prevent excessive inflow of sewage into the sewage treatment plant, thereby reducing the power cost of the treatment plant and reducing the difficulty of operating the sewage treatment plant due to the inflow of water.

As described above, it can be seen that the present invention provides a significantly improved stormwater flow control apparatus. While exemplary embodiments of the present invention have been shown and described, various modifications and other embodiments may be made by those skilled in the art. Such modifications and other embodiments will be considered and included in the appended claims without departing from the true spirit and scope of the invention.

According to the storm drain control apparatus according to the present invention as described above, it is possible to prevent the usual overflow accident, it is possible to prevent the storm storms clogged by the impurities.

In addition, the opening and closing of rainwater soils is automatically made according to the flow rate of sewage, thereby saving time and money required for rainwater soil management.

In addition, by controlling the collection volume by considering the flow rate and water quality of the sewage flowing into the stormwater chamber, it is possible to collect the maximum pollutant load in the limited collection channel capacity, thus maximizing the efficiency of the collection channel and The inflow of sewage, which does not need to be transferred to the treatment plant, can reduce the difficulty of operating the plant due to waste of power costs for the sewage treatment and deterioration of inflow water quality.
