The present invention also discloses a control method for online treatment of the combined system of storage tanks, emergency flood corridors and drainage pumping stations: the control system of the control box 11 is preset with a dangerous water level height H ₁ , and the dangerous water level height H ₁ is less than The highest height H ₂ of the water tank 3 is 1mm≤H ₂ -H ₁ ≤3mm; the real-time water level height in the drainage pool 4 obtained by monitoring the second liquid level gauge 8 is H ₃ , and H ₃ is equal to the water level of the natural water body; The real-time water level height in the sump 2 monitored by the first liquid level gauge 7 is H ₄ ; the real-time height of the weir gate door plate of the bottom opening weir gate 6 is H ₅ ;

When it is sunny and H ₄ <H ₁ , the drainage pump 9 is closed, and H ₅ >H ₃ ; when it is rainy and H ₄ <H ₁ , the drainage pump 9 is closed, H ₃ increases, and the bottom opening weir gate 6 is in the control box 11 rises under control, H ₅ increases with the increase of H ₃ and H ₅ >H ₃ ; when it rains and H ₄ >H ₁ and H ₅ <H ₃ , the bottom opening weir gate 6 is closed and drainage The pump 9 works under the control of the control box 11, and the water in the sump 2 is discharged into the drainage basin 4.

When using this invention:

1. When it is sunny, the on-line processing storage tank 1 does not enter the water. At this time, the height of the top of the weir door panel of the bottom opening weir gate 6 is higher than the height of the water level in the drainage tank.

2. When it rains, the first liquid level gauge 7 in the sump 2 monitors that the real-time water level in the sump 2 does not exceed the dangerous water level preset by the control box 11. At the same time, the water level of the natural water body rises due to rainfall, so the drainage pool 4 The real-time water level will rise with the rise of the water level of the natural water body. At this time, the second liquid level gauge 8 in the drainage pool 4 will feed back the real-time water level signal monitored to the control box 11 so as to drive the weir gate plate of the lower opening weir gate 6 to rise. The top height of the weir gate door plate is always positioned at the upper end of the real-time water level of the drainage pond 4 .

3. When the rain time is too long or the rainstorm is too long, the first liquid level gauge 7 in the sump 2 monitors that the real-time water level in the sump 2 exceeds the dangerous water level preset by the control box 11, indicating that the water level in the drainage area 4 is too high, The weir door plate of the bottom-opening weir gate 6 rises to the limit position, the bottom-opening weir gate 6 is in a closed state, and the drainage is not smooth; at this time, the control box 11 controls the drainage pump 9 to work to forcefully drain the rainwater in the sump to prevent rainwater pour back.

4. When heavy rainfall occurs and the on-line processing storage tank is too late to deal with it, the hydraulic automatic gate 12 on the water diversion corridor 14 is opened to discharge the flood.

The bottom-opening weir gate of the present invention adopts gravity water outlet in a sunny day or a light rain state, and only when the gravity water outlet is too late, the drainage pump 9 is turned on to realize strong drainage.

It should be understood that the above description is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of Any changes or substitutions should fall within the protection scope of the present invention.
