Abstract
Description
Technical Field
[0001] This application relates to the field of drainage technology, and more specifically, to a drainage system for saline-alkali soil. Background Technology
[0002] Saline-alkali land often suffers from poor drainage, soil salinization, and secondary salinization. Poor drainage is detrimental to crop growth. To prevent soil salinization, drainage structures need to be installed in saline-alkali land to improve yields.
[0003] The prior art publication (announcement) document with the number CN216930769U provides a drainage system for saline-alkali land. In this related technology, after the brine collected in the collection well reaches a certain level, the switch of the second pump is turned on. The brine collected in the collection well is pumped out through the second pumping pipe, the second pump, and the drainage pipe. At this time, the brine flowing out of the drainage pipe is recycled, and after professional treatment, the brine is discharged.
[0004] Although the existing technical solutions mentioned above can achieve the relevant beneficial effects through the existing technical structure, they still have the following defects: the water collected in the sump not only cannot play an automatic discharge function, but also requires electric drive for discharge, resulting in poor drainage performance.
[0005] In view of this, we propose a soil drainage system for saline-alkali land. Utility Model Content
[0006] To address the problems mentioned in the background art, this application provides a soil drainage system for saline-alkali land.
[0007] The saline-alkali land drainage system provided in this application adopts the following technical solution:
[0008] A drainage system for saline-alkali land includes a collection well, a manifold and a discharge cylinder are fixedly connected to the outside of the collection well, and multiple infiltration cylinders are fixedly connected to one side of the manifold in a linear, equally spaced structure. Cotton and linen columns are inserted inside the infiltration cylinder and the manifold, and the discharge cylinder is installed at a lower height than the manifold.
[0009] By adopting the above technical solution, the collection well connects the manifold and the discharge pipe. When the infiltration pipe buried in the soil layer collects the excess water into the collection well through the manifold, the water in the collection well is automatically discharged through the discharge pipe due to the height difference between the discharge pipe and the manifold, thus ensuring a good drainage effect of the drainage system.
[0010] As an optional solution to the technical solution of this application, the water collection well is composed of two parts, a well cylinder and a well cover, which are hinged together. A water baffle is fixedly connected to the inner wall of the well cylinder. An extension plate is slidably connected to one side of the water baffle. An electric telescopic rod is hinged to one end of the extension plate. The other end of the electric telescopic rod is hinged to the side wall of the well cylinder through a hinge seat.
[0011] By adopting the above technical solution, a water collection well is formed by hinged connection of the well barrel and the well cover. After the well cover is flipped open, maintenance operations can be carried out on the drainage structure inside the well barrel. Furthermore, the extension and retraction adjustment of the electric telescopic rod can drive the extension plate to adjust its height, thereby regulating the water storage inside the water collection well. This allows the drainage structure to store and retain water according to the water requirements of different crops, meeting the needs of crop growth.
[0012] As an optional solution to the technical solution in this application, a water pump is fixedly connected to one side of the manhole cover, a water delivery pipe is fixedly connected to the output pipe end of the water pump, a suction pipe is fixedly connected to the input pipe end of the water pump, and the suction pipe passes through the discharge cylinder and is fixedly connected to a filter cylinder.
[0013] By adopting the above technical solution and using a water pump, external water can be drawn into the well through a suction pipe, causing the water inside the well to flow in reverse, replenishing the soil, improving the survival rate of crops, and thus achieving high yield.
[0014] As an optional solution to the technical solution in this application, the water supply pipe is arranged with an inclined structure.
[0015] By adopting the above technical solution, water can be discharged at the closed end of the well shaft and then flow in reverse by using a water pipe with an inclined structure.
[0016] As an optional solution to the technical solution in this application, a buoyancy ring is slidably connected to the outside of the filter cartridge.
[0017] By adopting the above technical solution, the buoyancy ring can be used to protect the outside of the filter cartridge, causing it to float under changes in water level, thereby scraping and cleaning the outside of the filter cartridge and ensuring the permeability of the filter cartridge.
[0018] In summary, this application includes at least one of the following beneficial technical effects:
[0019] 1. This application connects the manifold and the discharge pipe by using a water collection well. When the infiltration pipe buried in the soil layer collects the excess water into the water collection well through the manifold, the water in the water collection well is automatically discharged through the discharge pipe due to the height difference between the discharge pipe and the manifold, thus ensuring a good drainage effect of the drainage system.
[0020] 2. This application utilizes a water pump to draw external water into the well shaft through a suction pipe, causing the water inside the well shaft to flow in reverse, replenishing the soil, improving crop survival rate, and thus achieving high yield. Attached Figure Description

[0025] The present application will be further described in detail below with reference to the accompanying drawings.
[0026] Reference Figure 1-3 The saline-alkali soil drainage system described in this application includes a water collection well 1. A manifold 2 and a discharge cylinder 3 are fixedly connected to the outside of the water collection well 1. Multiple infiltration cylinders 4 are fixedly connected to one side of the manifold 2 in a linear and equally spaced structure. Cotton and linen columns 5 are inserted inside the infiltration cylinders 4 and the manifold 2, and the discharge cylinder 3 is lower than the installation height of the manifold 2.
[0027] This saline-alkali soil drainage system connects the collection well 1 with the confluence pipe 2 and the discharge pipe 3. When the infiltration pipe 4 buried inside the soil layer collects excess water into the collection well 1 through the confluence pipe 2, the water in the collection well 1 is automatically discharged through the discharge pipe 3 due to the height difference between the discharge pipe 3 and the confluence pipe 2, thus ensuring a good drainage effect of the drainage system.
[0028] Reference Figure 3 and Figure 1 The water collection well 1 in the saline-alkali soil drainage system described in this application embodiment is composed of two parts, a well cylinder 11 and a well cover 12, which are hinged together. A water-proof plate 13 is fixedly connected to the inner wall of the well cylinder 11. An extension plate 14 is slidably connected to one side of the water-proof plate 13. An electric telescopic rod 15 is hinged to one end of the extension plate 14. The other end of the electric telescopic rod 15 is hinged to the side wall of the well cylinder 11 through a hinge seat.
[0029] This saline-alkali soil drainage system uses a well shaft 11 and a well cover 12 hinged together to form a water collection well 1. After the well cover 12 is flipped open, maintenance operations can be performed on the drainage structure inside the well shaft 11. The extension and retraction adjustment of the electric telescopic rod 15 can drive the extension plate 14 to adjust its height, thereby regulating the water storage inside the water collection well 1. This allows the drainage structure to store and retain water according to the water requirements of different crops, meeting the needs of crop growth.
[0030] Reference Figure 3 and Figure 1 In the saline-alkali soil drainage system described in this application embodiment, a water pump 16 is fixedly connected to one side of the well cover 12, a water delivery pipe 17 is fixedly connected to the output pipe end of the water pump 16, a water suction pipe 18 is fixedly connected to the input pipe end of the water pump 16, the water suction pipe 18 passes through the discharge cylinder 3 and is fixedly connected to a filter cylinder 19, and the water delivery pipe 17 is set with an inclined structure, wherein a buoyancy ring is slidably connected to the outside of the filter cylinder 19.
[0031] This saline-alkali soil drainage system utilizes a water pump 16 to draw external water into the well 11 through a suction pipe 18, causing the water inside the well 11 to flow in reverse, replenishing the soil, improving crop survival rates, and ultimately achieving high yields. The inclined water pipe 17 discharges water to the closed end of the well 11 for reverse flow, and the buoyancy ring protects the outside of the filter cylinder 19, causing it to float with changes in water level, thus scraping and cleaning the outside of the filter cylinder 19 and ensuring its permeability.
[0032] Working principle: When water seeps into the soil layer and flows through the infiltration cylinder 4 to the confluence cylinder 2, and then into the collection well 1, the water level in the collection well 1 rises continuously. After the water level exceeds the height of the extension plate 14, the excess water is discharged through the discharge cylinder 3, so that the water volume inside the collection well 1 is kept appropriate.
[0033] When the crop requires a large amount of water, the length of the electric telescopic rod 15 is shortened so that the extension plate 14 is raised, and the water-blocking plate 13 is stacked to achieve water accumulation inside the water collection well 1.
[0034] When the weather is relatively dry and crops need to be watered, the water pump 16 is started to draw in external water, which is collected in the water collection well 1 and flows in reverse through the manifold 2 to wet the soil.
