[0002] At present, the soil salinity three-dimensional salt regulating and controlling device is a device used to regulate and control soil salinity. Irrigation water flows in the soil pores, dissolving the salt and bringing it to the lower soil layer. This process is similar to the effect of dissolution and scouring. Due to the existence of the drainage system, water containing high salt can be discharged, thereby reducing the salt content of the upper soil layer. Many saline-alkali lands are difficult to grow crops due to excessive salt. By using this three-dimensional salt regulating and controlling device, the soil salinity can be effectively reduced, making the saline-alkali land gradually suitable for growing crops. When the salt-laden water is discharged through pipes to control the salt in the soil, the water will carry the soil along with it as it seeps downward. The soil will easily clog the pipes when it moves with the water, affecting the discharge of the seeping water and making it impossible for the salt in the soil to be discharged along with the water, thereby controlling the salt in the soil.

The soil driven by the seeping water passes through the strip grooves at the bottom of the outer cover tube, so that the bottom of the inner wall of the outer cover tube fits tightly with the bottom of the outer side of the inner guide tube, so that the soil can enter the inner guide tube from the contact position together with the flowing water, and be introduced into the water collection system with the flowing water, so as to avoid the infiltrating water driving the soil to enter the pipe and fail to flow with the water flow, resulting in soil accumulation, blocking the water inlet gap of the pipe, making it impossible for the water containing salt to be discharged smoothly, affecting the salt control effect, both ends of the inner wall of the outer cover tube are fixedly installed with sealing end rings, the inner wall of the sealing end ring is tightly fitted with the two ends of the outer side of the inner guide tube, and both ends of the inner guide tube are fixedly installed with connectors, and the inner guide tube is connected to the water collection system through the connectors.

[0005] Preferably, a grating plate is fixedly installed on the inner wall of the water collecting box, and the grating plate divides the interior of the water collecting box into two areas, and the top of the outer side of the grating plate is evenly provided with grating grooves. The grating plate cooperates with the drain pipe, and when the seeping water is pumped out, the grating plate divides the interior of the water collecting box into two areas, and the water inlet position and the water outlet position are separated, so as to avoid the suction force during extraction from driving a large amount of soil entrained by the water, and prevent the soil from entering the extraction pipeline together with the water.

When the water in the irrigation pipe gradually increases and the water outlet hole on the upper side of the outer side of the irrigation pipe begins to be discharged, the irrigation water discharge pressure is increased by cooperating with the inner push rod and the water pressure, so that when the water is discharged from the upper water outlet hole, it can be sprayed out a farther distance, so that the land is evenly irrigated and the salt in the soil is more evenly entrained to infiltrate, and the outer side of the inner push rod is arc-shaped.

[0008] The present invention provides a soil salinity three-dimensional salt regulation and control device, which has the following beneficial effects: 1. The three-dimensional soil salt regulating and controlling device cooperates with the inner conduit through the outer cover tube. When diverting the seeping water, the inner conduit is wrapped by the outer cover tube to increase the contact area with the soil. At the same time, the spiral hollow groove is used to make the seeping water enter the inner part of the outer cover tube better. After the water enters the outer cover tube, the soil driven by the seeping water passes through the strip groove at the bottom of the outer cover tube, so that the bottom of the inner wall of the outer cover tube is tightly fitted with the bottom of the outer side of the inner conduit, so that the soil can enter the inner conduit together with the flowing water from the contact position, and is introduced into the water collection system with the flowing water, so as to avoid the seeping water driving the soil to enter the pipe and fail to flow with the water flow, resulting in soil accumulation, blocking the water inlet gap of the pipe, making it impossible for the water carrying salt to be smoothly discharged, and affecting the salt control effect.

[0009] 2. The soil salinity three-dimensional salt regulation and control device guides the water introduced into the water collecting tank through a drainage pipe, so that when the water is introduced into the water collecting tank, it is introduced from the bottom layer of the internal space of the water collecting tank, so that the soil entrained in the water directly enters the bottom of the internal space of the water collecting tank, thereby preventing the soil from directly entering the extraction position, causing the extraction pipe to be blocked by the soil, and making it impossible to extract the water entrained with salt.

[0010] 3. The soil salinity three-dimensional salt regulation and control device cooperates with the drainage pipe through the grid plate. When extracting the seeping water, the grid plate divides the inside of the water collecting tank into two areas, separating the water inlet position and the water outlet position, avoiding the suction force during extraction to drive a large amount of soil entrained by the water, and preventing the soil from entering the extraction pipeline together with the water.

[0011] Fourth, the three-dimensional soil salinity regulating and controlling device increases the distance between the two sides of the inner push rod and the water outlet of the irrigation pipe from top to bottom through the arc of the inner push rod. When the water in the irrigation pipe gradually increases and begins to be discharged from the upper water outlet of the outer side of the irrigation pipe, the inner push rod cooperates with the water pressure to increase the irrigation water discharge pressure, so that when the water is discharged from the upper water outlet, it can be sprayed out to a farther distance, so that the land can be evenly irrigated and the salt in the soil can be more evenly entrained to infiltrate.

[0012] 5. The three-dimensional soil salinity control device cooperates with the arc cover plate through the hollow floating rod. After the water level around the irrigation pipe rises, the hollow floating rod drives the arc cover plate to move together, blocking the water outlet below the outer side of the irrigation pipe to prevent floating impurities on the soil surface from blocking the water outlet below. At the same time, the inner push rod and water pressure are cooperated to increase the water pressure when the water is discharged from the upper water outlet, so that the water can diffuse to a farther range, make the soil and water fully contact, and make the water better carry the salt in the soil to infiltrate.

A spiral hollow groove is provided, and an inwardly concave strip groove is provided at the center position of the bottom of the outer cover tube 21. Sealing end rings 24 are fixedly installed at both ends of the inner wall of the outer cover tube 21. The inner wall of the sealing end ring 24 is tightly fitted with the two ends of the outer side of the inner conduit 22. The strip depression at the center position of the bottom of the outer cover tube 21 prevents a gap from appearing at the bottom between the outer cover tube 21 and the inner conduit 22, so that the soil driven by the infiltration of salt entrained by water can pass through the strip groove of the inner conduit 22 together with the water after entering the outer cover tube 21, and enter the water collection system 3 driven by the water flow. Connectors 25 are fixedly installed at both ends of the inner conduit 22, and the inner conduit 22 is connected to the water collection system 3 through the connector 25.

[0017] The second embodiment is based on the first embodiment. Figure 6 to Figure 7 As shown, the water collection system 3 includes a water collection box 31, a connecting pipe 33 is fixedly installed on the top of the water collection box 31, and the connecting pipe 33 is evenly installed on the top of the water collection box 31 along the axial direction, and the end of the connecting pipe 33 away from the water collection box 31 is connected to the inner conduit 22 through the connector 25, and a drainage pipe 34 is fixedly installed on the top of the inner wall of the water collection box 31. The drainage pipe 34 is evenly installed inside the water collection box 31 along the axial direction, and the connecting pipe 33 is connected to the inner conduit 22 through the connector 25, so that the derived water enters the drainage pipe 3 along the connector 25 and the connecting pipe 33 4, enters the water collecting box 31 through the drainage pipe 34. When introduced into the water collecting box 31, the drainage pipe 34 cooperates with the grille plate 35. When the water carrying salt is introduced, the water is discharged from the bottom layer of the internal space of the water collecting box 31 under the action of the drainage pipe 34, so that the soil impurities in the water directly enter the bottom layer of the water collecting box 31, and the top end of the drainage pipe 34 penetrates the water collecting box 31 and extends to the outside thereof, the top end of the drainage pipe 34 is fixedly connected to the inner wall of the connecting pipe 33, and there is a gap between the bottom end of the drainage pipe 34 and the bottom of the inner wall of the water collecting box 31.

[0018] A grid plate 35 is fixedly installed on the inner wall of the water collecting box 31. The grid plate 35 divides the inside of the water collecting box 31 into two areas, and the top of the outer side of the grid plate 35 is evenly provided with grid grooves. A water pumping pipe 37 is fixedly installed on the inner wall of the water collecting box 31. The water pumping pipe 37 is located on the side of the grid plate 35 away from the drain pipe 34, and an empty groove is provided at the bottom of the outer side of the water pumping pipe 37. The grid plate 35 divides the inside of the water collecting box 31 into two areas. The water is filtered through the grid grooves on the top of the outer side of the grid plate 35, so that the water collection capacity reaches When it reaches a certain level, the water containing salt passes through the grille plate 35 and enters the area of ​​the pumping pipe 37. The water containing salt is pumped by the pumping pump 6 using the connecting pipe 7, so that the water enters the connecting pipe 7 through the pumping pipe 37 and the fixed joint 32, and the salt in the soil is pumped out together with the water, so as to control the salt content in the soil. An outer sliding cover 36 is slidably installed on the outer side of the pumping pipe 37, and a fixed joint 32 is fixedly installed on the bottom end of the pumping pipe 37. The top end of the fixed joint 32 is connected to the water inlet of the pumping pump 6 through the connecting pipe 7.

[0019] The third embodiment is based on the first and second embodiments. Figures 8 to 9 As shown, the irrigation system 4 includes a fixed pipe 41, the water inlet of the fixed pipe 41 is connected with the water outlet of the irrigation water pump 5 through a pipeline, and the water outlet of the fixed pipe 41 is fixedly installed with a flange joint 42, and the fixed pipe 41 is fixedly connected with the irrigation pipe 43 through the flange joint 42. The water drawn by the irrigation water pump 5 is discharged from the water outlet, enters the fixed pipe 41 through the pipeline, and is introduced into the irrigation pipe 43 through the flange joint 42 at the water outlet of the fixed pipe 41. The irrigation water source is discharged through the water outlet holes symmetrically arranged on the outside of the irrigation pipe 43 and flows into the soil surface, so that the water source entrains the salt in the soil and continuously infiltrates. The outside of the irrigation pipe 43 is symmetrically provided with water outlet holes, and the top of the inner wall of the irrigation pipe 43 is fixedly installed with an inner push rod 44, and the outer side of the inner push rod 44 is arc-shaped.

[0020] Arc groove plates 47 are fixedly installed at both ends of the outer side of the irrigation pipe 43. The outer side of the arc groove plate 47 is evenly provided with convex blocks, and the bottom of the outer side of the arc groove plate 47 is provided with arc grooves. Hollow floating rods 45 are slidably installed at the arc grooves of the arc groove plate 47. The hollow floating rods 45 are symmetrically installed along the center position of the axis of the arc groove plate 47, and arc cover plates 46 are fixedly installed on the outer side of the hollow floating rods 45. During the irrigation process, the water source in the irrigation pipe 43 is firstly discharged from the water outlet at the bottom to irrigate the soil on both sides of the irrigation pipe 43, and at the same time, the water source in the irrigation pipe 43 is firstly discharged from the water outlet at the bottom to irrigate the soil on both sides of the irrigation pipe 43. The debris on both sides of the irrigation pipe 43 impacts and flushes it open. When the water infiltration speed is low, the water level around the irrigation pipe 43 rises, and at the same time drives the hollow float rod 45 to slide in the arc groove of the arc groove plate 47, rising with the water level. During the sliding process, the arc cover plate 46 is driven to close the water outlet below the outer side of the irrigation pipe 43. The arc cover plate 46 is located between the arc groove plates 47, and the two ends of the arc cover plate 46 are in contact with the opposite surfaces of the arc groove plates 47. The side of the arc cover plate 46 close to the irrigation pipe 43 is arc-shaped and fits the outer side of the irrigation pipe 43.

[0021] During use, the salt content of the land is tested by the test personnel. When the salt content is high, the irrigation water pump 5 and the pumping water pump 6 are controlled by the control system 1. When the salt content of the land surface is high, the irrigation water pump 5 extracts water with a lower salt content and transports it to the irrigation system 4 through a pipeline to irrigate the land, so that the water with a lower salt content absorbs the salt in the soil and continuously infiltrates to take away the salt in the soil. When the water infiltrates to the position of the drainage system 2, the infiltrating water carries the salt in the soil into the drainage system 2, and the incoming water is guided by the drainage system 2 to flow into the water collection system 3 at both ends. After entering the water collection system 3, the pumping water pump 6 is controlled by the control system 1 to pump out the water with a higher salt content collected in the water collection system 3 through the connecting pipe 7, thereby achieving the control of the salt content of the land.

[0022] When the soil is irrigated by the irrigation system 4, the water pumped by the irrigation water pump 5 is discharged from the outlet, enters the fixed pipe 41 through the pipeline, and is introduced into the irrigation pipe 43 through the flange joint 42 at the outlet of the fixed pipe 41. The irrigation water source is discharged through the outlet holes symmetrically arranged on the outside of the irrigation pipe 43 and flows into the soil surface, so that the water source entrains the salt in the soil and continuously infiltrates. At the same time, during the irrigation process, the water source in the irrigation pipe 43 is first discharged from the lowest outlet hole to irrigate the soil on both sides of the irrigation pipe 43, and at the same time, it impacts the debris on both sides of the irrigation pipe 43 and flushes it open. When the water infiltration speed is low, the water level around the irrigation pipe 43 rises, and at the same time drives the hollow float rod 45 to slide in the arc groove of the arc groove plate 47, rising with the water level, and driving the arc cover plate 46 to close the outlet hole below the outer side of the irrigation pipe 43 during the sliding process.

[0023] When the irrigation water carries salt and infiltrates into the drainage system 2, the water carrying salt enters the outer cover pipe 21 through the spiral grooves on the surface of the outer cover pipe 21. After entering the inner cover pipe 21, the water enters the inner conduit 22 through the grooves of the support groove ring 23 inside the outer cover pipe 21 and the grooves on the surface of the inner conduit 22. The water is guided to the water collection system 3 on both sides through the inner conduit 22. At the same time, the strip-shaped depression at the center of the bottom of the outer cover pipe 21 eliminates a gap at the bottom between the outer cover pipe 21 and the inner conduit 22, so that the soil driven by the infiltration of the water carrying salt can pass through the grooves of the inner conduit 22 together with the water after entering the outer cover pipe 21, and enter the water collection system 3 driven by the water flow.

[0024] When the water containing salt is introduced into the water collection system 3 through the drainage system 2, the connecting pipe 33 is connected with the inner conduit 22 through the connector 25, so that the water flows out along the connector 25 and the connecting pipe 33 into the drainage pipe 34, and then enters the water collection tank 31 through the drainage pipe 34. When the water containing salt is introduced into the water collection tank 31, the drainage pipe 34 cooperates with the grid plate 35, and when the water containing salt is introduced, the water is led out from the bottom layer of the internal space of the water collection tank 31 under the action of the drainage pipe 34, so that the soil impurities in the water are directly discharged. The water enters the bottom layer of the water collecting box 31, and the grille plate 35 divides the inside of the water collecting box 31 into two areas. The water is filtered through the grille grooves on the top of the outer side of the grille plate 35. When the water collection volume reaches a certain level, the water containing salt passes through the grille plate 35 and enters the area of ​​the pumping pipe 37. The water containing salt is pumped by the pumping pump 6 through the connecting pipe 7, so that the water enters the connecting pipe 7 through the pumping pipe 37 and the fixed joint 32, and the salt in the soil is pumped out together with the water, so as to control the salt content in the soil.
