[0038] Among them, a filter screen is arranged on the top of the collection tray 13, and the periphery of the collection tray 13 is pre-buried in a concave position on the ground. In addition to the filter screen arranged on the top, a filter screen is also arranged on the circumference of the ground arrangement to perform step interception.

[0039] Among them, an electric cylinder 1401 is fixedly installed on the upper part of the electromagnetic gate valve 14, and the telescopic end of the electric cylinder 1401 is connected to the gate valve body 1402. The gate valve body 1402 fits and slides in the electromagnetic gate valve 14. When the electric cylinder 1401 contracts, the gate valve body 1402 is lifted to open the electromagnetic gate valve 14.

[0040] Among them, two groups of valve pistons 2001 are fixedly arranged above the middle connection of the double-control valve 20, and the telescopic end of the valve piston 2001 is fixedly arranged with a valve plate page 2002, and the valve plate page 2002 is inserted in the valve piston 2001 to control the closure; a guide frame 2101 is fixedly arranged on the inner rear side of the protection chamber 21, and a sliding block 2102 is slidably arranged on the front side of the guide frame 2101; side pistons 2103 are fixedly arranged on the front ends of both sides of the guide frame 2101, and the telescopic ends of the side pistons 2103 on both sides are fixed on both sides of the sliding block 2102; a control electric cylinder 2104 is fixedly arranged on one side of the guide frame 2101, and the telescopic end of the control electric cylinder 2104 is fixedly connected to the sliding block 2102; the side pistons 2103 on both sides are respectively connected with the two groups of valve pistons 2001; a connecting chamber 22 is fixedly arranged at the rear end of the rear tee 19, a downpipe is arranged at the bottom of the connecting chamber 22, and a limiting rod 2201 is fixedly arranged at the middle rear of the connecting chamber 22.

[0041] When this embodiment is used, all parts except the photovoltaic base station 1 and the collecting tray 13 are pre-buried, and maintenance wells are set for parts that need to be frequently inspected, such as the water quality detector 4, the flow meter 5, the branch solenoid valve 6, etc. The specific number and specifications are determined according to the actual project needs. The photovoltaic base station 1 is later built on the ground, and the side of the collecting tray 13 is buried in a concave position on the ground, and the edge is kept flush with the ground; the length of the connecting straight pipe 3 and the corrugated pipe 8 is customized as needed, and buried at a depth of 1-1.2 meters below the ground in the planting area. The end of the corrugated pipe 8 away from the connecting straight pipe 3 is tilted upward, retaining a certain slope for drainage; the photovoltaic base station 1 provides power generation function and provides a source of electricity. The water quality detector 4, flow meter 5, branch solenoid valve 6, upper solenoid valve 12, electric cylinder 1401, control electric cylinder 2104 and two-way water pump 23 are all provided with lines extending to the power distribution processing warehouse 101, and remote control is provided by the remote transmission antenna 102 to ensure the strength of the signal; the transmitting end of the remote transmission antenna 102 transmits a signal, which is received by the control terminal program and then decided and controlled. The control terminal program can be a mobile phone APP or a computer application software. Manual control and automatic control are set to automatically execute various tasks when the manual response times out.

[0042] Under normal conditions, the upper solenoid valve 12 and the solenoid gate valve 14 are closed, the rear double-control valve 20 is open, and the double-control valve 20 connected to the two-way water pump 23 on the side is closed. When the groundwater level rises, or when the upper part is fully irrigated, the water body enters the bellows 8 after intercepting the sediment through the sand core filter layer 9, passes through the connector 7 from the bellows 8 to enter the connecting straight pipe 3, passes through the branch solenoid valve 6, the flow meter 5 and the water quality detector 4 in turn, enters the main integrated tee 2 and converges, and finally flows into the connecting bin 22 and is discharged through the drainage ditch to achieve drainage and desalination.

[0043] The soil moisture content and salinity are monitored daily to understand the soil moisture content and other indicators. At the same time, drainage is regulated according to the flow rate and other indicators measured by the flow meter 5 and the EC and other indicators measured by the water quality detector 4. If the EC of the drainage water body is lower than the set threshold, the drainage is stopped and the branch electromagnetic valve 6 is closed to avoid excessive drainage and waste of water resources. If the EC of the water body meets the standard, but the soil salt content is still high, the low salt water can be reused. The state of the two sets of side pistons 2103 is swapped by controlling the electric cylinder 2104 to control the movement of the sliding block 2102, and then the two sets of valve pistons 2001 drive the two sets of valve plate leaves 2002 to swap, so that the two-way water pump 23 is connected to the main integrated tee 2. The two-way water pump 23 can be used to pump water out of the ground, and then connected to the irrigation equipment on the ground for irrigation and salt washing. In addition, in order to ensure that the soil has a certain moisture content and avoid drought in crops due to soil water shortage, the branch electromagnetic valve 6 can be closed when the salt content does not affect the growth of crops to reduce the drainage volume.

[0044] In the arid areas of Northwest China, rainstorms are prone to occur in summer. It is difficult for a short period of heavy rain to fully infiltrate, which may lead to floods, soil erosion and destruction of farmland infrastructure. At this time, the upper solenoid valve 12 can be opened to directly use the channel formed by the main integrated tee 2 to transmit and discharge water from underground to the drainage ditch, thereby alleviating the flood control pressure on the upper farmland and protecting the farmland infrastructure.

[0045] When long-distance water delivery is required, the main integrated tee 2 can also serve as a water delivery pipeline to reduce irrigation costs. In particular, when the water quality of the drainage ditch is good and the soil salt content is high, the water in the drainage ditch can be pumped out by the two-way water pump 23, transported through the main integrated tee 2, and discharged from the collection tray 13 to flood the soil and drain salt.

[0046] Embodiment 2:

[0047] Please refer to the instruction manual Figures 5 to 7 :

[0048] After long-term operation of embodiment 1, it is inevitable that silt and salt crystals will accumulate inside the main integrated tee 2. When it is necessary to remove salt crystals and silt during long-term operation, the crystal removal robot 17 is remotely controlled to work to achieve the purpose of removing salt crystals and silt.

Piston 1706; eight groups of guide rods 1707 are fixedly provided at the front end of the motor seat 1701, and positioning seats 1708 are slidably provided in two adjacent groups of guide rods 1707, and the positioning seats 1708 are fixedly connected to the telescopic end of the moving piston 1706; positioning pistons 1709 are fixedly provided on the outside of the positioning seats 1708, and rubber clamping feet 1710 are fixedly provided on the telescopic end of the positioning piston 1709; the outsides of the four groups of positioning seats 1708 are connected by connecting air pipes 1711, and a turning pipe is provided at the side of the connecting air pipes 1711 to the rear and is connected to a micro air pump B1712; a ring-shaped battery compartment 1713 is fixedly provided at the front end of the guide rod 1707.

[0051] Among them, two sets of annular electrodes for docking and charging are arranged at the front end of the annular battery compartment 1713 and the rear end of the annular electrode seat 1501.

[0052] Among them, two groups of centrally symmetrical cleaning rubber blades 1801 are fixedly arranged on the outside of the processing shaft 18, and the cleaning rubber blades 1801 are attached to the inner wall of the main integrated tee 2; and an exhaust fan 1802 is fixedly arranged on the outside of the processing shaft 18.

[0053] When this embodiment is used, first close all branch electromagnetic valves 6 to drain the water in the main integrated tee 2 as much as possible to reduce the water content of sediment in the pipeline. Open the electromagnetic gate valve 14 to connect the main integrated tee 2 with the outside world, and transmit signals through the internal control antenna 16 to control the crystal removal robot 17 to work.

[0054] When the crystal removal robot 17 needs to be moved, the remote control micro air pump A1705 and the micro air pump B1712 work, the micro air pump A1705 controls the air pressure in the traveling piston 1706, and then the traveling piston 1706 drives the positioning seat 1708 to move, and the micro air pump B1712 controls the air pressure in the positioning piston 1709, which can control the extension and retraction of the rubber foot 1710, and the double extension and retraction of the traveling piston 1706 and the positioning piston 1709 can be used to move forward and backward: first extend the positioning piston 1709, then extend the traveling piston 1706, and then contract the positioning piston 1709, and then contract the traveling piston 1706, and repeat this process to push the crystal removal robot 17 to move backward as a whole; conversely, the traveling piston 1706 can be extended first, then the positioning piston 1709 is extended, and then the traveling piston 1706 is contracted, and then the positioning piston 1709 is contracted, so as to prompt the crystal removal robot 17 to return to the front tee 11;

[0055] At the same time, the driving motor 1702 is started to drive the processing shaft 18 to rotate, and the cleaning rubber blade 1801 and the exhaust fan 1802 rotate synchronously. The cleaning rubber blade 1801 scrapes the salt crystals on the inner wall of the main integrated tee 2 and breaks up the sediment deposited at the bottom. The exhaust fan 1802 blows the salt crystals and the broken sediment backwards, thereby further dispersing the sediment and salt crystals. After the crystal removal is completed, the crystal removal robot 17 is reset to Figure 7 When the front end of the annular battery compartment 1713 contacts the rear end of the annular electrode holder 1501, the battery stops moving and starts charging.

[0056] The limit rod 2201 can limit the movable range of the crystal removal robot 17. After resetting, the electromagnetic gate valve 14 is closed, the upper electromagnetic valve 12 is opened, and water is poured into the main integrated tee 2 through the collection plate 13. The water is discharged through the connecting bin 22 to achieve the cleaning of the sediment and salt crystals in the pipeline, making the cleaning more thorough.
