In addition, in the present invention, since the control water level can be maintained by operating the control flood gate, there is no risk of flooding downstream, and even if the control water gate is opened in advance before it starts to rain, there is no risk of all water upstream flowing out. Furthermore, because the above-mentioned control sluice is mainly operated, not only is there less burden on sediment inflow from the lower part, but the unmanned automatic control of the upper overflow type does not generate a large flow rate, and there is no risk of discharging all water, so there is less concern about safety accidents. Since the control water level is maintained only with the above-mentioned control gate, there is an effect of reducing power.

Next, in a state where the upper overflow is being achieved, the control water gate (20) is opened by the winch (5) based on the second excess water level height value (2.25 m) that exceeds the first excess water level height value (2.15 m). ) rises, allowing interrupted discharge through the lower part of the discharge groove 110 of the main sluice 10 for a certain period of time.

For example, when the management water level value calculated by the management water level calculation unit corresponds to the second excess water level height value (2.25 m) set through the setting unit, the main water gate 10, as shown in FIGS. 7 and 8, The control sluice 20 is raised to a certain height in the upper direction of the main sluice 10 by the lifter 5 so that intermediate discharge can be achieved through the lower part of the discharge groove 110, thereby opening the main sluice 10. The lower part of the discharge groove 110 may be partially opened for a certain period of time (5 minutes).

Figure 9 is a front view schematically showing the main sluice gate raised along with the control sluice gate for middle and lower discharge, and Figure 10 is a side view of Figure 9.

Next, in a state where interrupted discharge is being performed, the control gate (20) is opened by the lifter (5) based on the third excess water level height value (2.35 m) that exceeds the second excess water level height value (2.25 m). ), the main sluice gate 10 rises to a certain height, so that intermittent discharge and lower discharge through the lower part of the main sluice gate 10 can be performed for a certain period of time.

For example, when the management water level value calculated by the management water level calculation unit corresponds to the third excess water level height value (2.35 m) set through the setting unit, as shown in FIGS. 9 and 10, the main water gate 10 The main sluice 10 is operated together with the control sluice 20 by the lifter 5 so that lower discharge can be achieved along with intermediate discharge through the lower part of the discharge groove 110 and the lower part of the main sluice 110. It can be raised to a certain height for a certain amount of time (5 minutes).

Figure 11 is a front view schematically showing the main sluice gate raised higher than the initial elevation height for bottom discharge, and Figure 12 is a side view of Figure 11.

Next, in a state where bottom discharge is being performed along with middle discharge, the lifter (5) based on the fourth excess water level height value (more than 2.36 m) exceeds the third excess water level height value (2.35 m). The main sluice gate 10 may be raised higher than the initial rise height for a certain period of time and the control sluice gate 20 may be raised for a certain period of time.

For example, when the management water level value calculated by the management water level calculation unit corresponds to the fourth excess water level height value (2.36 m or more) set through the setting unit, the main water gate 10, as shown in FIGS. 11 and 12 The main sluice 10 is opened by the lifter 5 for a certain period of time ( It can rise higher than the initial rise height for 3 minutes) and the control water gate 20 can be raised for a certain period of time (3 minutes).

In this way, in the present invention, since the control water level can be maintained by operating the control flood gate (20), there is no risk of flooding downstream, and even if the control flood gate (20) is opened in advance before it starts to rain, all the water upstream is lost. There is no fear of it escaping, and furthermore, since the control sluice 20 mainly operates, not only is there less burden on the inflow of lower sediments, but the unmanned automatic control of the upper overflow type does not generate a large flow rate, and there is no risk of discharge of all water. There is less risk of safety accidents, and there is an advantage in that there is a power reduction effect because the control water level is maintained only with the control water gate 20.

Figure 13 is an enlarged rear view schematically showing an example of a guide roller part, and Figure 14 is a schematic diagram of one side fixed water stop rubber, one side protruding water stop rubber, the other side fixed water stop rubber, and the other side protruding water stop rubber of an example guide roller part and an example water stop part. This is a partially enlarged floor plan shown as .

Next, in order to smoothly raise and lower the control sluice gate (20), the control water gate 20 is moved from one side to the other side of the control water gate 20 and from the other side of the control water gate 20 to one side.

It is located in between and can be manually rotated forwards and backwards and moved left and right in place together with the auxiliary movement axis 213c.

In this way, the position of the guide roller part 21 can be adjusted by moving left and right depending on the left and right spacing between the guide rail 140 of the main water gate 10 and the guide roller part 21 of the control water gate 20. The control water gate 20 can move up and down more smoothly.
