The hump tops of the siphons 28 are flush with the water level 12 of the water retaining building 13. A ventilation pipeline 27 and an electromagnetic valve 41 are provided at the top of each siphon 28. Water inlets of the siphons 28 are all bell-shaped, and the water inlets of the siphons 28 are all located at the lower portion of the upstream side of the base 26, and are all located between every two vertical partitions 22 in the water filter tank 18. A water outlet of each siphon 28 is located on the downstream side of the base 26. The water outlets of the siphons 28 are all round nozzles. The water outlets are provided with a flap valve 36 separately. The flap valves 36 slope to the downstream. The top surface of the base 26 is provided with an operation room 43, and a row of photovoltaic panels 44 is mounted on a roof of the operation room 43. A water pump 39 is mounted in the operation room 43. A water inlet pipe 37 of the water pump 39 penetrates into the water filter tank 18 along the upstream surface of the base 26. A filter 38 is disposed on the water inlet pipe 37. A water outlet pipe of the water pump 39 communicates with a pressure water pipe 35 in the base 26. Water level sensors 42 are mounted on the upstream and downstream surfaces of the base 26 of the siphonic drainage 25 to monitor the river level, the underground water level and the sea level. Water quality sensors 40 are mounted on plate walls of the vertical partitions 22 in the water filter tank 18 to monitor the change of the water quality of the estuary underground reservoir 11. Round water permeable plates 21 are arranged on the sloping plate 20 of the water filter tank 18. The water permeable plates 21 are all ^-shaped micro-arched plates.

The base 26 rides on a soil foundation 10 on both sides of the cut-off wall 14. A bottom surface of a middle portion of the base 26 is connected to a top surface of the cut-off wall 14. The pipe wall of the water curtain section 32 of the siphon 28 is provided with a circle of water outlet holes 33 distributed at equal intervals.

The device adopts an upstream face of the water fdter tank 18 as a sloping plate 20, and a micro-arched water permeable plate 21 is disposed on the sloping plate 20, which is advantageous for filtering underground water in a large area, and being large in bearing capacity and structural stress. The base 26 of the siphon 28 has a saddle-shaped cross section. The base 26 rides on a soil foundation 10 on both sides of the water retaining wall 14, which is advantageous for reducing the self-weight and the structural stress, and fixing the siphon 28. A circle of water outlet holes is provided on the pipe wall of the water curtain section 32 of the siphon 28, and the lower edge of each water outlet hole has a circular arc-shaped drainage groove, which is advantageous for forming a closed water curtain when water is drained from the water outlet holes, such that a vacuum is formed in the hump section 30. The continuously effluent water in the water outlet holes will form a pipe flow in the water outlet section 31 under the action of gravity, and under the action of atmospheric pressure, the water level in the water inlet section 29 will rise over the hump top to form a siphoning, such that the siphon 28 achieves drainage in the presence of a small water head difference.
When the device is in operation, the photovoltaic panel 44, the water pump 39, the electromagnetic valve 41, a flap valve tum-on/off sensor, the water level sensor 42 and the water quality sensor 40 are first connected to a control cabinet through a cable, and the control cabinet is powered on to prepare for changing water to ensure the water quality of the estuary underground reservoir 11.
When water in the estuary underground reservoir 11 does not need to be changed during a water storage period, since the hump top of the siphon 28 is the height of the water level 12 of the water retaining building 13, as long as the electromagnetic valve 41 is turned on, air is allowed to enter the siphon 28 from the ventilation pipeline 27, a vacuum is not formed in the hump section 30, and the water of the river 4 does not flow into the sea 1 regardless of the change of a sea level
2. Since the water outlets of all the siphons 28 are provided with the flap valves 36, the flap valves 36 close the water outlets of the siphons 28 under the action of the self-weight and the water pressure of the sea 1, and seawater does not flow into the estuary underground reservoir 11. When the water level of the river is higher than the water level 12 of the water retaining building 13 and the sea level 2, river water automatically flows to the sea 1 through gaps of the underground gravels 8, the plurality of water filter pipes 16, the water filter tank 18, the row of siphons 28 and the flap valves 36 thereof, and the stilling pool 17. In order to increase the drainage amount of the siphon 28, the electromagnetic valve 41s of the ventilation pipelines 27 on all the siphons 28 are turned off, a vacuum is generated in the hump section 30 of the siphon 28, a siphon is formed under the action of atmospheric pressure, the water in the estuary underground reservoir 11 is drained into the sea 1 with a large drainage amount, and the water in the estuary underground reservoir 11 is changed. When the water level of the river is lower than the crest level of the hump section in the siphon 28 and higher than the sea level 2 and the water in the estuary underground reservoir 11 needs to be changed, the electromagnetic valve 41 on the ventilation pipeline 27 is turned off, and then the water pump 39 is turned on to make water sprayed from all the water outlet holes 33 via the pressure water pipe 35 and the water circulation ring 34 and gathered into a closed water curtain in the water curtain section 32, such that a vacuum is formed in the hump section 30, the water in the estuary underground reservoir 11 is drained into the sea 1 through the siphon 28 under the action of siphoning, and the water pump 39 is turned off after the siphonic water discharge is generated in the siphon 28, and until the water level of the river is flush with the sea level 2 or lower than the sea level 2, the siphon 28 will no longer drain. When the water level of the river rises above the sea level 2 or the sea level 2 drops below the river level, the electromagnetic valve 41 is repeatedly turned off, the water pump 39 is turned on, a closed water curtain is generated in the water curtain section 32, a vacuum is formed in the hump section 30 again, and the siphon 28 continues to drain.

(2) When the water level of the river is lower than the hump top of the siphon 28 and higher than the sea level 2, the siphon 28 siphons for drainage: the water level sensors 42 mounted on the upstream and downstream sides of the base 26 transmit signals of the water level of the river or the underground water level and the sea level 2 to the control cabinet, the water quality sensor 40 mounted in the water fdter tank 18 transmits a water quality signal of the estuary underground reservoir 11 to the control cabinet, and the control cabinet controls the electromagnetic valve 41 and the water pump 39 according to a set operation scheme and program. When the water quality sensor 40 outputs a signal indicative of that the water quality of the estuary underground reservoir 11 does not meet the standard requirements, the control cabinet controls to turn off the electromagnetic valve 41 and turn on the water pump 39, water in the water outlet pipe of the water pump 39 is sprayed from the water outlet holes 33 to form a closed water curtain through the pressure water pipe 35 and the water circulation ring 34 on the water curtain section 32, a vacuum is generated in the hump section 30 to form a siphon under the action of atmospheric 5 pressure, and the water in the estuary underground reservoir 11 is drained into the sea 1 through the water inlet section 29, the hump section 30, the water curtain section 32, the water outlet section 31 and the flap valve 36 of the siphon 28. When the water quality sensor 40 outputs a signal indicative of that the water quality of the estuary underground reservoir 11 meets the standard requirements, the control cabinet controls to turn on the electromagnetic valve 41, and air 10 is input into the hump section 30 of the siphon 28 from the ventilation pipeline 27, such that a vacuum is not formed in the hump section 30, the siphon 28 cannot siphon, and the water in the estuary underground reservoir 11 is not drained into the sea 1.
