The water inlet of the siphon 61 is close to the bottom of the water collecting well 1, but needs to be kept a certain distance away from the bottom of the water collecting well 1 to ensure that the water body smoothly enters the siphon 61. The siphon drainage system 6 is used for conveying the water in the water collecting well 1 to the drainage ditch 9 through the siphon 61 by utilizing the siphon principle when the water level in the water collecting well 1 is higher than the water level in the drainage ditch 9.

The diameter of siphon 61 may be determined based on the proximity of siphon discharge flow to the sump 1 control area discharge design flow.
In this embodiment, the vacuum pump 65 is preferably a water-ring vacuum pump 65 with a minimum power of 0.81KW, the pumping rate is 450L/min, and under normal conditions, the water-ring vacuum pump 65 can pump air in the siphon 61 completely within 1 minute, and is rapid in pumping and response speed, so that the drainage efficiency of the system is higher.
It is understood that the vacuum pump 65 in the present embodiment may also adopt other types, powers and pumping rates of the vacuum pump 65, which can be determined according to the specific situation.
In this embodiment, the power is solar photovoltaic power generation 5, drives suction pump 3 and draws water the work, realizes continuously incessantly drawing water.
When the power supply is a solar photovoltaic power generation power supply 5, the solar photovoltaic power generation power supply 5 comprises a solar cell panel 51 and an inverter 52. The solar panel 51 is connected to the water pump 3 via the inverter 52. The solar panel 51 is configured to receive solar radiation and convert light energy into direct current electric energy, and the inverter 52 is configured to convert the direct current electric energy into alternating current electric energy to supply power to the water pump 3.
In this embodiment, the siphon drainage mode and the water pump 3 drainage mode are alternately operated day and night. Specifically, in the water discharge mode of the water suction pump 3, which is operated alone in the daytime, the solar cell panel 51 supplies alternating current to the water suction pump 3 through the inverter 52, and the water suction pump 3 discharges the water in the water collection well 1 into the water discharge ditch 9 through the water discharge pipe 4. And at night, the solar photovoltaic power generation power supply 5 does not supply power to the water suction pump 3, the water discharge mode of the water suction pump 3 does not operate, the siphon 61 is vacuumized through the vacuum pump 65 at the moment, when the water outlet pipe 66 connected with the water outlet of the vacuum pump 65 can completely discharge water flow (namely no gas exists in the discharged water flow), the check valve 64 on the air inlet pipe 63 is turned off at the moment, the vacuum pump 65 is controlled to stop working, so that the water body in the water collecting well 1 can be directly discharged into the drainage ditch 9 through the siphon 61, the vacuum pump 65 and the water outlet pipe 66 can be directly pulled out at the moment, and the water suction pump is connected into the water collecting well when used next time.
Based on field observation, the water level of a water collecting well 1 in the existing solar energy hidden pipe drainage system at night rises and is restored to be close to the peripheral underground water level, the water level of the water collecting well 1 is higher than the water level of a drainage ditch 9, so that a forward water level difference is formed between the water collecting well 1 and the drainage ditch 9, at the moment, in order to improve the drainage efficiency, auxiliary drainage at night is feasible by adopting a siphon drainage mode, the drainage efficiency can be higher, and compared with a mode of paving a power line or adding a storage battery for the continuous drainage of a water suction pump 3, the method for auxiliary drainage at night by adopting the siphon drainage mode has lower drainage cost.
In this embodiment, can also add the battery on solar photovoltaic power generation 5's basis, charge for the battery through solar cell panel 51, the battery can last for the suction pump 3 power supply to solve the problem that solar photovoltaic power generation 5 can not supply power when night or cloudy.

In this embodiment, the inverter 52 may further have a water level control function, and the water level control function sets a water level control command for the water pump 3 in the inverter 52 to ensure that the orifice (i.e., the water inlet) of the siphon 61 is submerged in water all the time. When the water level in the water collecting well 1 and the distance between the pipe orifices of the siphon pipes 61 inserted into the water collecting well 1 reach the preset threshold value, the inverter 52 stops supplying power to the water suction pump 3, the siphon drainage system 6 is prevented from stopping working after the water level of the water collecting well 1 is lower than the pipe orifices of the siphon pipes 61, and the siphon drainage mode is invalid, so that the siphon drainage system 6 can continuously and stably run, and the integral drainage efficiency of the device is ensured.
In this embodiment, the preset threshold is preferably 0.5m, that is, when the distance between the water level of the water collecting well 1 and the orifice of the siphon 61 reaches 0.5m, the water pumping mode of the water pump 3 fails to work, so as to ensure the stable operation of the siphon water pumping mode, and after the water level of the water body injected into the water collecting well 1 by the water collecting pipe 2 increases, the water pump 3 is started to perform water pumping. It is easy to understand that even if the water level of the water collecting well 1 is lower than the orifice of the siphon pipe 61 to cause the siphon drainage system 6 to be ineffective, after the water level is up, the air in the siphon pipe 61 can be pumped by the vacuum pump 65, and the siphon drainage mode is opened again.
It should be noted that the preset threshold in this embodiment is set to 0.5m, which is only a preferred value, and is not fixed and unique, and may also be set to a value of 0.4m, or a value of 0.8m, 1.0m, etc., and any value corresponding to the specific value of the preset threshold should be within the protection scope of the present invention.

If a method of adding a storage battery on the basis of the solar cell panel 51 is adopted, assuming that the pumping power of the water pump 3 is 2.2KW and the reduction coefficient is 0.65, the required output power of the solar cell panel 51 is about 3.4 KW. The sunlight irradiation time is 8 hours, if a siphon drainage mode or a communication drainage mode is adopted, the operation is carried out from 20 nights to 6 morning in the next morning, the operation is carried out for 10 hours totally, the operation is calculated according to the configuration of a storage battery for 10 hours, a 2.2KW water suction pump 3 consumes 2.2 degrees of electricity when operating for 1 hour, 22 degrees of electricity is consumed when operating for 10 hours, the storage battery with 24V100Ah has the storage capacity of 2.4 degrees, then 24V91.7Ah is required when operating for 2.2 degrees, 24V122.3Ah is actually required when operating for 2.2 degrees, and 24V1223Ah is required when operating for 10 hours, and the storage battery with the nominal capacity of 0.75 is taken as the actual capacity (considering the discharge depth). The actual output power of the 1KW solar panel 51 is 0.65KW, and when calculated according to 8 hours running time, the power generation amount is 5.2 degrees per day, and the 22-degree power generation amount needs to be additionally provided with about 4.2KW solar panels, so that it can be seen that the cost of laying the solar panel 51 is increased by at least 1.2 times, and in addition, the cost of the storage battery needs to be considered. Therefore, the drain cost for adding the storage battery is significantly increased. Obviously, although the method of adding a storage battery or installing an electric wire can improve the overall drainage efficiency, compared with the method of auxiliary drainage in the siphon drainage mode proposed in embodiment 1 or self-flowing drainage in the connected drainage mode proposed in embodiment 2, the method of the present invention is obviously superior in technical and economic cost, has lower cost and higher drainage efficiency, and is also beneficial to environmental protection.
