The water in the water storage tank can be excess water collected during the flood season, or can be introduced from elsewhere. The water pump can also be started to supply water to the water storage tank when the siphon is not draining.
[0029] The water collecting pool 18 is a trapezoidal pool, the front plate 19 of the water collecting pool 18 is inclined to the upstream, and the rear plate 21 of the water collecting pool 18 is inclined to the downstream. The front plate 19 is provided with a row of mutually spaced water filtering plates 20 parallel to the axis of the dam, the top of the front plate 19 is provided with a sediment trap 22, an inverted filter is laid between the front plate 19 and the sediment of the river bed 2, a plurality of partition walls 23 perpendicular to the dam axis are provided on the bottom plate of the water collecting pool 18, and a trash rack cover 24 is provided at the top of the water collecting pool 18. The role of the water filtering plate is to filter the water in the gravel of the river bed and prevent the sediment from entering the water collecting pool. Orifices are reserved in the construction of the front panel and then the water filtering plate is installed on the orifices. The role of the sediment trap is to stop the sediment on the river bed from entering the water collecting pool. The concrete of the sediment trap is poured on the top surface of the front plate. The role of the inverted filter is to filter the water between the gravels of the river bed. When the foundation pit of the water collecting pool is excavated, the inverted filter material is first laid and then the front plate is constructed.

A flip pit 29 is provided on the inner wall of the straight-through pipe 26 at the extension of the center line of the branch pipe a 27, and the flip pit 29 has a pit surface with a circular' arc shape. When the water flows into the branch pipe a, it rushes to the flip pit 29 and is deflected by the flip pit, which is advantageous to rapidly realizing siphonic water discharge at the beginning of siphoning. During the siphonic water discharge process, the pressure of the water flow in the outlet pipe can be increased and the kinetic energy of the water flow in the outlet pipe can be increased so that the pipe flow can always be formed in the outlet pipe for siphonic water discharge. The lower portion of the straight-through pipe 26 is communicated with a branch pipe b 28, the water inlet of the branch pipe b 28 is communicated with the outlet pipe 16 of the corresponding water pump 15, and the branch pipe b 28 intersects with the upper portion of the straight-through pipe 26 at an angle of intersection of less than 90o. The water outlet of the branch pipe b is located at the side of the straight-through pipe, and the position of the water outlet of the branch pipe b should not affect the deflecting action of the flip pit as much as possible. The branch pipe b 28 is connected to the circular arc of the inner wall of the lower portion of the straight-through pipe 26, reducing water head loss, and avoiding cavitation.

When a short circuit occurs between the two contacts, the sensor outputs a signal. The water outlet sensor of the embodiment is simple in structure, durable, and low in cost. In the technical solution of the present invention, a commercially available conventional water flow sensor can also be selected as the water outlet sensor.
[0031] As shown in Lig. 6, the housing 36 of the negative pressure sensor 35 has a cylindrical shape, an elastic disc 37 is provided at a front end of the housing 36, and a water stop is provided between the housing 36 and the elastic disc 37.

In the embodiment, the negative pressure sensor 35 is provided for instructing the situation that a negative pressure is formed in the hump pipe. When the siphon fault occurs, the siphon is easily repaired (for example, the siphon is insufficiently airtight, resulting in the fact that a negative pressure cannot be formed and siphoning cannot be achieved). The negative pressure sensor of the embodiment is simple in structure, durable, and low in cost. In the technical solution of the present invention, a commercially available conventional negative pressure sensor can also be selected as the negative pressure sensor.
[0032] Embodiment 2 [0033] The embodiment provides a method for siphonic water replacing using floodwater resources in a reservoir, comprising the following steps.
AO 19.09.1071 NL [0034] (1) On the dam 6, a plurality of mutually spaced inlet pipes 9 are installed along the upstream dam slope, the water inlets of the inlet pipes 9 are installed at the bottom of the water collecting pool 18, a plurality of mutually spaced humps pipe 10 are installed along the dam top, a drainage device 25 is installed at the end of the hump pipes 10, a plurality of mutually spaced outlet pipes 11 are installed along the downstream dam slope, the water outlets of the outlet pipes 11 are all located at the bottom of the inside of the apron 7, and the inlet pipe 9, the hump pipe 10, the drainage device 25 and the outlet pipe 11 are sequentially connected from the upstream to the downstream to form a row of parallel siphons 8. An air inlet 12 is installed in the through hole at the top of the downstream side of all the hump pipes 10, a negative pressure sensor 35 and an inlet valve are installed on the air inlets 12, and a water outlet sensor 30 is installed in the through hole at the top of the water outlet of all the outlet pipes 11.
[0035] (2) A water storage tank 13 is built and a photovoltaic panel is installed on the bank 3 at two dam abutments, the water delivery pipes 14 of the left water storage tank 13 are laid to each of the siphons 8 on the left side of the dam 6, and each of the water delivery pipes 14 is communicated with the branch pipe a 27 of the respective drainage device 25 through the valve a. The water delivery pipes 14 of the right water storage tank 13 are laid to each of the siphons 8 on the right side of the dam 6, and each of the water delivery pipes 14 is communicated with the branch pipe a 27 of the respective drainage device 25 through the valve a.
[0036] (3) Respective waterpumps 15 and control cabinets 17 are installed beside each of the siphons 8 at the top of the dam 6, the inlet pipes of all the water pumps 15 extend below the upstream water level 4 of the dam 6, and the outlet pipes 16 of all the water pumps 15 are communicated with the branch pipe b 28 of the respective drainage device 25 through the valve b. The photovoltaic panels are coupled with the cables of all the control cabinets 17, and all the control cabinets 17 are coupled with the cables of the respective water pump 15, the valve a, the valve b, the inlet valve, the negative pressure sensor 35 and the water outlet sensor 30.
[0037] (4) The drainage device 25 causes the siphon 8 for siphonic water discharge: the control cabinet 17 turns off the inlet valve and the valve b and turns on the valve a, water in the water storage tank 13 flows from the water delivery pipe 14 into the branch
AO 19.09.1071 NL pipe a 27 of the drainage device 25, and the water flow deflects via the flip pit 29 and closes the water outlet of the outlet pipe 11. At the same time, the control cabinet 17 turns on the water pump 15 and the valve b, water flow enters the drainage device 25 from the branch pipe b 28, the pressure and the kinetic energy of the water flow in the outlet pipe 11 is increased. Water flows out from the water outlet after the outlet pipe 11 forms a pipe flow, the water outlet sensor 30 outputs a water outflow signal, the control cabinet 17 turns off the valve a, the water pump 15 and the valve b, and the water in the outlet pipe 11 continues to flow out from the water outlet under the action of gravity and inertia, so that a negative pressure is formed in the hump pipe 10. At this time, the negative pressure sensor 35 outputs a signal for generating a negative pressure in the hump pipe 10. Under the atmospheric pressure, the water upstream of the dam 6 is pressed into the siphon from the water inlet of the inlet pipe 9, the water level in the inlet pipe 9 gradually rises until it flows from the hump pipe 10 into the drainage device 25 and the outlet pipe 11, and water flows from the water outlet of the outlet pipe 11 into the apron 7 to form siphonic water discharge in the siphon 8 to replace the water in the bottom of the reservoir and the gravel layer in the bottom of the reservoir. During the siphonic water discharge process of the siphon 8, once the upstream and downstream water levels change, the siphonic water after flowing through the hump pipe 10 is deflected by the flip pit of the drainage device 25, so that the pipe flow can always be formed in the outlet pipe 11 for siphon water discharge. If no siphon 8 is required for water discharge, as long as the control cabinet 17 turns on the inlet valve to allow air to enter the siphon 8, the vacuum in the hump pipe 10 is destroyed, and the siphon 8 immediately stops water discharge.
