A three-dimensional soil salinity regulation and control device

Abstract

This invention discloses a three-dimensional soil salinity regulation and control device. This invention relates to the field of soil salinity control technology. Because water infiltrates and flows, it carries soil along with it, which can easily clog pipes and affect the outflow of infiltrated water. By using an outer casing pipe in conjunction with an inner conduit pipe, the outer casing pipe wraps around the inner conduit pipe during the drainage of infiltrated water, increasing the contact area with the soil. Simultaneously, a spiral groove is used to allow the infiltrated water to better enter the interior of the outer casing pipe. After the water enters the outer casing pipe, the soil carried by the infiltrated water passes through a strip-shaped groove at the bottom of the outer casing pipe, causing the bottom of the inner wall of the outer casing pipe to fit tightly against the bottom of the outer side of the inner conduit pipe. This allows the soil to enter the inner conduit pipe along with the flowing water from the contact point and be guided into the water collection system. This avoids soil accumulation and blockage of the pipe caused by the infiltrated water carrying soil into the pipe and being unable to flow with the water.

Description

Technical Field

[0001] This invention relates to the field of soil salinity control technology, specifically to a three-dimensional soil salinity regulation and control device. Background Technology

[0002] Currently, the three-dimensional soil salinity regulation and control device is a device used to regulate and control soil salinity. Irrigation water flows through the soil pores, dissolving salt and carrying it to the lower soil layer. This process is similar to the action of dissolution and flushing. Due to the existence of the drainage system, water containing high salt content can be discharged, thereby reducing the salt content of the upper soil layer. Many saline-alkali lands are difficult for crops to grow due to excessive salt content. By using this three-dimensional salt regulation and control device, soil salinity can be effectively reduced, making saline-alkali land suitable for crop cultivation.

[0003] When using pipes to drain water carrying salt to control soil salinity, the water infiltrates and flows, causing the soil to move along with it. This movement of soil can easily clog the pipes, affecting the drainage of the infiltrated water and preventing the salt in the soil from being drained away with the water, thus hindering the control of soil salinity. Summary of the Invention

[0004] To achieve the above objectives, the present invention provides the following technical solution: a three-dimensional soil salinity regulation and control device, comprising:

[0005] The control system has irrigation pumps and water pumps installed on its two sides respectively.

[0006] An irrigation system installed on the land surface, the irrigation system being connected to the outlet of an irrigation pump via pipes;

[0007] A drainage system, with water collection systems installed at both ends, and a connecting pipe installed at the top of the water collection system, which is connected to the inlet of a water pump through the connecting pipe.

[0008] Both the drainage system and the water collection system are buried deep in the soil, and the drainage system is located directly below the irrigation system.

[0009] The drainage system includes an inner conduit, on the outer side of which a supporting groove ring is fixedly installed. The supporting groove ring is axially and evenly installed on the outer side of the inner conduit, and has uniformly spaced through grooves on its outer side. The outer side of the inner conduit also has uniformly spaced strip grooves. An outer cover pipe is fixedly installed on the outer side of the supporting groove ring. The outer cover pipe has uniformly spaced spiral grooves on its outer side, and a recessed strip groove is located at the center of its bottom. Through the cooperation of the outer cover pipe and the inner conduit, when guiding infiltrated water, the outer cover pipe wraps around the inner conduit, increasing the contact area with the soil. Simultaneously, the spiral grooves allow the infiltrated water to better enter the interior of the outer cover pipe. After the water enters the interior of the outer cover pipe, it flows downwards... The seeping water carries soil through the grooved groove at the bottom of the outer casing, ensuring a tight fit between the bottom of the inner wall of the outer casing and the bottom of the outer side of the inner conduit. This allows the soil to enter the inner conduit along with the flowing water from the contact point and be guided into the water collection system. This prevents the seeping water from carrying soil that cannot flow with the water flow after entering the pipe, leading to soil accumulation, clogging the water inlet gap, and preventing the smooth discharge of water carrying salt, thus affecting the salt control effect. Both ends of the inner wall of the outer casing are fixedly installed with sealing end rings, and the inner walls of the sealing end rings are tightly fitted with both ends of the outer side of the inner conduit. Both ends of the inner conduit are fixedly installed with connectors, and the inner conduit is connected to the water collection system through the connectors.

[0010] Preferably, the water collection system includes a water collection tank, a connecting pipe fixedly installed on the top of the water collection tank, the connecting pipe being evenly installed axially on the top of the water collection tank, and the end of the connecting pipe away from the water collection tank being connected to an inner conduit via a connector. A drain pipe is fixedly installed on the top of the inner wall of the water collection tank, the drain pipe being evenly installed axially inside the water collection tank, and the top end of the drain pipe penetrating the water collection tank and extending to its outer side. The top end of the drain pipe is fixedly connected to the inner wall of the connecting pipe. The drain pipe guides the water entering the water collection tank, so that when the water enters the water collection tank, it is introduced from the bottom of the internal space of the water collection tank, allowing the soil carried in the water to directly enter the bottom of the internal space of the water collection tank, avoiding the soil directly entering the extraction position, causing the soil to block the extraction pipe and preventing the water carrying salt from being extracted. There is a gap between the bottom end of the drain pipe and the bottom of the inner wall of the water collection tank.

[0011] Preferably, a grating plate is fixedly installed on the inner wall of the water collection tank, which divides the interior of the water collection tank into two areas. The top of the outer side of the grating plate is evenly provided with grating grooves. By cooperating with the drain pipe, when pumping out the seeping water, the grating plate divides the interior of the water collection tank into two areas, separating the water inlet and outlet positions, thus preventing the suction force during pumping from carrying a large amount of soil with the water and preventing soil from entering the pumping pipe with the water. A pumping pipe is fixedly installed on the inner wall of the water collection tank. The pumping pipe is located on the side of the grating plate away from the drain pipe, and a slot is provided at the bottom of the outer side of the pumping pipe. An outer sliding cover is slidably installed on the outer side of the pumping pipe, and a fixed joint is fixedly installed at the top of the pumping pipe. The top of the fixed joint is connected to the inlet of the water pump through a connecting pipe.

[0012] Preferably, the irrigation system includes a fixed pipe, the inlet of which is connected to the outlet of an irrigation pump via a pipe, and a flange joint is fixedly installed at the outlet of the fixed pipe. The fixed pipe is fixedly connected to an irrigation pipe via the flange joint. The irrigation pipe has symmetrically arranged outlet holes on its outer side, and an inner push rod is fixedly installed at the top of the inner wall of the irrigation pipe. The arc shape of the inner push rod causes the distance between the two sides of the inner push rod and the outlet holes of the irrigation pipe to gradually increase from top to bottom. As the water in the irrigation pipe gradually increases and begins to flow out from the outlet holes on the upper outer side of the irrigation pipe, the inner push rod, in conjunction with the water pressure, increases the pressure of the irrigation water flow, allowing the water to spray a greater distance when it flows out from the upper outlet holes, thus ensuring uniform irrigation of the land and more evenly carrying salts in the soil for infiltration. The outer side of the inner push rod is arc-shaped.

[0013] Preferably, both ends of the outer side of the irrigation pipe are fixedly installed with arc-groove plates. The outer side of the arc-groove plates is uniformly provided with protrusions, and the bottom of the outer side of the arc-groove plates is provided with arc grooves. Hollow floats are slidably installed at the arc grooves of the arc-groove plates. The hollow floats are symmetrically installed along the center position of the axis of the arc-groove plates, and arc-shaped cover plates are fixedly installed on the outer side of the hollow floats. Through the cooperation of the hollow floats and the arc-shaped cover plates, after the water level around the irrigation pipe rises, the hollow floats drive the arc-shaped cover plates to move together, blocking the water outlet below the outer side of the irrigation pipe, preventing impurities floating on the soil surface from blocking the water outlet below. At the same time, in conjunction with the inner top rod and water pressure, the water pressure when water is discharged from the upper water outlet is increased, allowing the water to spread to a farther range, so that the soil and water can fully contact each other, and the water can better carry the salt in the soil to seep down. The arc-shaped cover plates are located between the arc-groove plates, and the two ends of the arc-shaped cover plates are in contact with the opposite surfaces of the arc-groove plates. The side of the arc-shaped cover plates near the irrigation pipe is arc-shaped and fits against the outer side of the irrigation pipe.

[0014] This invention provides a three-dimensional soil salinity regulation and control device. It has the following beneficial effects:

[0015] I. This three-dimensional soil salinity regulation and control device uses an outer casing pipe and an inner conduit pipe in conjunction. When guiding infiltrated water, the outer casing pipe wraps around the inner conduit pipe, increasing the contact area with the soil. At the same time, the spiral groove allows the infiltrated water to better enter the interior of the outer casing pipe. After the water enters the interior of the outer casing pipe, the soil carried by the infiltrated water passes through the strip groove at the bottom of the outer casing pipe, making the bottom of the inner wall of the outer casing pipe and the bottom of the outer side of the inner conduit pipe fit tightly. This allows the soil to enter the interior of the inner conduit pipe along with the flowing water from the contact point and be guided into the water collection system. This avoids the situation where the soil carried by the infiltrated water cannot flow with the water flow after entering the pipe, resulting in soil accumulation, clogging the water inlet gap of the pipe, and preventing the water carrying salt from being smoothly discharged, thus affecting the salinity control effect.

[0016] Second, this three-dimensional soil salinity regulation and control device guides the water into the collection tank through a drainage pipe, so that when the water enters the collection tank, it enters from the bottom of the internal space of the collection tank, allowing the soil carried in the water to directly enter the bottom of the internal space of the collection tank, avoiding the soil from directly entering the extraction position, causing the soil to block the extraction pipe and preventing the water carrying salt from being extracted.

[0017] Third, this three-dimensional soil salinity regulation and control device, through the cooperation of a grating plate and a drainage pipe, divides the inside of the water collection tank into two areas when extracting infiltrated water, separating the water inlet and outlet positions, to avoid the suction force during extraction carrying a large amount of soil with the water, and to prevent soil from entering the extraction pipeline along with the water.

[0018] IV. This three-dimensional soil salinity regulation and control device, through the arc shape of the inner top rod, gradually increases the distance between the two sides of the inner top rod and the water outlet of the irrigation pipe from top to bottom. As the water in the irrigation pipe gradually increases, when it begins to be discharged from the water outlet on the upper outer side of the irrigation pipe, the inner top rod, in conjunction with the water pressure, increases the pressure of the irrigation water discharge, allowing the water to be sprayed a longer distance when discharged from the upper water outlet, so that the land is evenly irrigated and the salt in the soil is more evenly infiltrated.

[0019] V. This three-dimensional soil salinity regulation and control device uses a hollow float and an arc-shaped cover plate to move the hollow float and arc-shaped cover plate together after the water level around the irrigation pipe rises. This blocks the water outlet below the outer side of the irrigation pipe, preventing floating impurities on the soil surface from clogging the lower water outlet. At the same time, in conjunction with the inner top rod and water pressure, the water pressure when water is discharged from the upper outlet is increased, allowing the water to spread to a farther range, ensuring full contact between the soil and water, and enabling the water to better carry salts in the soil and infiltrate downwards.

Detailed Implementation

[0030] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.

[0031] First embodiment, such as Figures 1 to 5 As shown, the present invention provides a technical solution: a three-dimensional soil salinity regulation and control device, comprising:

[0032] Control system 1, with irrigation water pump 5 and water pump 6 installed on both sides of the control system 1 respectively;

[0033] Irrigation system 4 is installed on the land surface and is connected to the outlet of irrigation pump 5 via a pipe.

[0034] Drainage system 2, with water collection system 3 installed at both ends, and connecting pipe 7 installed at the top of water collection system 3. Water collection system 3 is connected to the inlet of water pump 6 through connecting pipe 7.

[0035] Both drainage system 2 and water collection system 3 are buried deep in the soil, and drainage system 2 is located directly below irrigation system 4;

[0036] The drainage system 2 includes an inner conduit 22, on the outside of which a support groove ring 23 is fixedly installed. The support groove ring 23 is evenly installed axially on the outside of the inner conduit 22, and the outside of the support groove ring 23 is evenly provided with through grooves. The outside of the inner conduit 22 is evenly provided with strip grooves. An outer cover pipe 21 is fixedly installed on the outside of the support groove ring 23. Water carrying salt enters the interior of the outer cover pipe 21 through the spiral grooves on the surface of the outer cover pipe 21. After entering the interior, the water enters the inner conduit 22 through the grooves of the support groove ring 23 inside the outer cover pipe 21 and the strip grooves on the surface of the inner conduit 22. The water is then guided to the water collection systems 3 on both sides through the inner conduit 22. The outside of the outer cover pipe 21 is evenly provided with through grooves. The outer casing 21 has a spiral groove, and a recessed strip groove is provided at the center of the bottom of the outer casing 21. Sealing end rings 24 are fixedly installed at both ends of the inner wall of the outer casing 21. The inner wall of the sealing end ring 24 is tightly fitted to the two ends of the outer side of the inner conduit 22. The strip groove at the center of the bottom of the outer casing 21 ensures that there is no gap between the outer casing 21 and the inner conduit 22 at the bottom. This allows the soil carried by the water during the infiltration of salt to enter the outer casing 21 and pass through the groove of the inner conduit 22 with the water, and enter the water collection system 3 under the drive of 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 connectors 25.

[0037] The second embodiment is based on the first embodiment; please refer to [link / reference]. Figures 6 to 7As shown, the water collection system 3 includes a water collection tank 31. A connecting pipe 33 is fixedly installed on the top of the water collection tank 31. The connecting pipe 33 is evenly installed axially on the top of the water collection tank 31, and the end of the connecting pipe 33 away from the water collection tank 31 is connected to the inner conduit 22 through a connector 25. A drain pipe 34 is fixedly installed on the top of the inner wall of the water collection tank 31. The drain pipe 34 is evenly installed axially inside the water collection tank 31. The connecting pipe 33 is connected to the inner conduit 22 through the connector 25, so that the drained water enters the drain pipe 34 along the connector 25 and the connecting pipe 33. In step 4, water enters the water collection tank 31 through the drain pipe 34. When water is introduced into the water collection tank 31, the drain pipe 34 cooperates with the grid plate 35. When water carrying salt is introduced, the water is discharged from the bottom of the internal space of the water collection tank 31 under the action of the drain pipe 34, so that the soil impurities in the water directly enter the bottom of the water collection tank 31. The top of the drain pipe 34 penetrates the water collection tank 31 and extends to its outside. The top of the drain pipe 34 is fixedly connected to the inner wall of the connecting pipe 33, and there is a gap between the bottom of the drain pipe 34 and the bottom of the inner wall of the water collection tank 31.

[0038] A grating plate 35 is fixedly installed on the inner wall of the water collection tank 31, dividing the interior of the water collection tank 31 into two areas. The top of the outer side of the grating plate 35 has evenly spaced grating grooves. A water suction pipe 37 is fixedly installed on the inner wall of the water collection tank 31, located on the side of the grating plate 35 away from the drain pipe 34. The bottom of the outer side of the water suction pipe 37 has a hollow groove. The grating plate 35 divides the interior of the water collection tank 31 into two areas, filtering water through the grating grooves on the top of the outer side of the grating plate 35, thus increasing the water collection volume. Once a certain amount is reached, the water carrying salt passes through the grid plate 35 and enters the area of ​​the pumping pipe 37. The water pump 6 uses the connecting pipe 7 to pump the water carrying salt, 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 extracted along with the water, thus controlling the salt content in the soil. An outer sliding cover 36 is slidably installed on the outside of the pumping pipe 37, and a fixed joint 32 is fixedly installed at the top of the pumping pipe 37. The top of the fixed joint 32 is connected to the inlet of the pumping pipe 6 through the connecting pipe 7.

[0039] The third embodiment is based on embodiments one and two; please refer to [link / reference]. Figures 8 to 9As shown, the irrigation system 4 includes a fixed pipe 41. The inlet of the fixed pipe 41 is connected to the outlet of the irrigation pump 5 through a pipe. A flange joint 42 is fixedly installed at the outlet of the fixed pipe 41. An irrigation pipe 43 is fixedly connected to the fixed pipe 41 through the flange joint 42. The water pumped by the irrigation pump 5 is discharged from the outlet, enters the fixed pipe 41 through the pipe, 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 symmetrically arranged outlet holes on the outside of the irrigation pipe 43 and flows into the soil surface, so that the water source carries the salt in the soil and continuously seeps down. The irrigation pipe 43 has symmetrically opened outlet holes on the outside, and an inner top rod 44 is fixedly installed on the top of the inner wall of the irrigation pipe 43. The outer side of the inner top rod 44 is arc-shaped.

[0040] Both ends of the outer side of the irrigation pipe 43 are fixedly installed with arc-groove discs 47. The outer side of the arc-groove discs 47 is evenly provided with protrusions, and the bottom of each outer side of the arc-groove disc 47 has an arc groove. Hollow floats 45 are slidably installed in the arc grooves of the arc-groove discs 47. The hollow floats 45 are symmetrically installed along the center of the axis of the arc-groove discs 47, and arc-shaped cover plates 46 are fixedly installed on the outer side of the hollow floats 45. During irrigation, the water in the irrigation pipe 43 is first discharged through the lowest outlet hole to irrigate the soil on both sides of the irrigation pipe 43, while simultaneously irrigating the irrigation... Debris impacts both sides of the irrigation pipe 43, causing it to be pushed aside. When the water infiltration rate is low, the water level around the irrigation pipe 43 rises, simultaneously causing the hollow float 45 to slide within the arc groove of the arc groove plate 47, rising along with the water level. During the sliding process, the arc cover plate 46 seals 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 both 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 closest to the irrigation pipe 43 is arc-shaped and fits against the outer side of the irrigation pipe 43.

[0041] In use, the salinity of the soil is tested by inspectors. When the salinity is high, the irrigation pump 5 and the water pump 6 are controlled by the control system 1. When the salinity of the soil surface is high, the irrigation pump 5 draws water with lower salinity and delivers it to the irrigation system 4 through pipelines to irrigate the land. The water with lower salinity absorbs the salt in the soil and continuously infiltrates, carrying away the salt. When the water infiltrates to the drainage system 2, the infiltrated water carries the salt in the soil into the drainage system 2. The drainage system 2 guides the incoming water to flow into the collection systems 3 at both ends. After entering the collection system 3, the water pump 6 is controlled by the control system 1 and pumps out the water with higher salinity collected in the collection system 3 through the connecting pipe 7, thereby controlling the salinity of the soil.

[0042] When irrigating the soil through the irrigation system 4, the water pumped by the irrigation pump 5 is discharged from the outlet and enters the fixed pipe 41 through the pipe. At the outlet of the fixed pipe 41, it is introduced into the irrigation pipe 43 through the flange joint 42. The irrigation water source is discharged through the symmetrically arranged water outlets on the outside of the irrigation pipe 43 and flows into the soil surface, so that the water source carries the salt in the soil and continuously seeps down. At the same time, during the irrigation process, the water source in the irrigation pipe 43 is first discharged from the bottom water outlet to irrigate the soil on both sides of the irrigation pipe 43. At the same time, it impacts and washes away the debris on both sides of the irrigation pipe 43. When the water seepage rate is low, the water level around the irrigation pipe 43 rises, which drives the hollow float 45 to slide in the arc groove of the arc groove plate 47 and rises with the water level. During the sliding process, the arc cover plate 46 drives the lower water outlet on the outside of the irrigation pipe 43 to close.

[0043] When irrigation water carrying salt seeps into drainage system 2, the salt-laden water enters the outer casing pipe 21 through the spiral groove on its surface. After entering, the water flows into the inner conduit pipe 22 through the groove of the support ring 23 inside the outer casing pipe 21 and the groove on the surface of the inner conduit pipe 22. The inner conduit pipe 22 then guides the water to the water collection systems 3 on both sides. At the same time, the strip-shaped indentation at the center of the bottom of the outer casing pipe 21 ensures that there is no gap between the outer casing pipe 21 and the inner conduit pipe 22 at the bottom. This allows the soil carried by the salt-laden water during its infiltration to enter the outer casing pipe 21 and then pass through the groove of the inner conduit pipe 22 along with the water, and enter the water collection system 3 under the influence of the water flow.

[0044] When water carrying salt is introduced into the water collection system 3 through the drainage system 2, the connecting pipe 33 is connected to the inner conduit 22 through the connector 25, allowing the water to flow along the connector 25 and the connecting pipe 33 into the drain pipe 34. The water then enters the water collection tank 31 through the drain pipe 34. During the introduction into the water collection tank 31, the drain pipe 34, in conjunction with the grating plate 35, directs the water carrying salt from the bottom of the water collection tank 31's interior space, allowing soil impurities in the water to be directly discharged. The water enters the bottom layer of the water collection tank 31. At the same time, the grating plate 35 divides the inside of the water collection tank 31 into two areas. The water is filtered through the grating groove on the top of the outer side of the grating plate 35. After the water collection reaches a certain level, the water carrying salt passes through the grating plate 35 and enters the area of ​​the water pumping pipe 37. The water pump 6 uses the connecting pipe 7 to pump the water carrying salt. The water enters the connecting pipe 7 through the water pumping pipe 37 and the fixed joint 32, and the salt in the soil is extracted along with the water to control the salt content in the soil.

All other embodiments obtained by those skilled in the art and related fields based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention.
