Description

Technical Field

[0001] The utility model relates to the field of environmental management, in particular to a device for improving and managing saline-alkali land. Background Art

[0002] There are many reasons for the formation of saline-alkali land. Natural factors, such as drought, can cause groundwater levels to rise, bringing salt to the surface. Evaporation of the water leaves the salt in the soil's surface. Furthermore, coastal areas are affected by seawater infiltration, which can increase soil salinity.

[0003] Traditionally, saline-alkali land improvement methods rely on freshwater irrigation, which dissolves the salt in the soil and drains it away. However, this approach has several drawbacks: Freshwater irrigation requires large quantities of water, leading to significant waste of water resources. Furthermore, in areas with high groundwater levels, freshwater irrigation can hinder the timely removal of moisture from the soil, resulting in excessive soil moisture and plant death. To address these shortcomings, we propose a device for improving and managing saline-alkali land. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a device for improving and treating saline-alkali land.

[0005] In order to solve the problems existing in the prior art, the present invention adopts the following technical solution: a device for improving and treating saline-alkali land, comprising:

[0006] saline-alkali land;

[0007] The drainage structure includes a saline-alkali land water suction pipe and a water delivery pipe pre-buried in the saline-alkali land, wherein a partition is fixedly installed on the inner wall of the water delivery pipe, and the partition is used to divide the interior of the water delivery pipe into a drainage chamber and a water inlet chamber;

[0008] An irrigation structure comprising a water reservoir opened on the surface of saline-alkali land and a water supply component;

[0009] The water supply assembly includes a water supply pipe buried in the inner wall of the saline-alkali land, a spray pipe fixedly installed on the surface of the water supply pipe, and a pumping component arranged inside the water reservoir.

[0010] Preferably, the pumping component includes a water pump fixedly installed on the inner wall of the water reservoir, a tee pipe fixedly installed on the water outlet end of the water pump, and a water inlet pipe and a circulation pipe respectively connected to the tee pipe.

[0011] Preferably, the circulation pipe is located inside the water reservoir, and the end of the water inlet pipe away from the water pump is connected to the interior of the water inlet cavity.

[0012] Preferably, solenoid valves are provided on the surfaces of the water inlet pipe and the circulation pipe, and a nozzle is provided on the surface of the circulation pipe.

[0013] Preferably, one end of the spray pipe extends above the saline-alkali land.

[0014] Preferably, one end of the water supply pipe is connected to the interior of the water inlet cavity, one end of the saline-alkali land water suction pipe is connected to the interior of the drainage cavity, and one end of the water delivery pipe extends to the interior of the water reservoir.

[0015] Preferably, a gate is provided at the drainage end of the water reservoir, and an overflow groove is provided on the surface of the gate.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. By setting up drainage structures and irrigation structures, in areas with high groundwater levels, the saline-alkali land suction pipe can be used to absorb moisture in the saline-alkali soil above the saline-alkali land suction pipe into the saline-alkali land suction pipe, and then discharged into the reservoir along the drainage cavity. Afterwards, saline-alkali modifiers can be added to the reservoir, and the irrigation structure can be used to draw the water and saline-alkali modifiers in the reservoir into the spray pipe, and the saline-alkali land can be sprayed, thereby improving the soil of the saline-alkali land. The excess water and saline-alkali modifiers sprayed into the saline-alkali land will be reabsorbed by the saline-alkali land suction pipe and then discharged into the reservoir, thereby recycling water resources and avoiding waste of water resources.

[0018] 2. By setting up a pumping component, when the saline-alkali improver is poured into the water reservoir, the solenoid valve on the surface of the water inlet pipe is closed, and the solenoid valve on the surface of the circulation pipe is opened, and then the water pump is driven to work, so that the water in the water reservoir can be pumped into the circulation pipe by the water pump, and then sprayed back into the water reservoir along the nozzle. The water flow sprayed from the nozzle is used to drive the flow of water in the water reservoir, thereby accelerating the mixing of the saline-alkali improver with the water in the water reservoir.

[0019] 3. By setting up a water pipe, the interior of the water pipe is divided into a drainage chamber and a water inlet chamber by a partition. Therefore, the drainage chamber can be used to discharge the excess water transported in the saline-alkali land suction pipe, and the water pumped in by the water pump can be transported along the inside of the water inlet chamber to the water supply pipe, thereby reducing the laying of pipelines and saving costs.

DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0029] See also Figure 1-6 The utility model provides a technical solution: a device for improving and managing saline-alkali land, comprising: saline-alkali land 1, a drainage structure, and an irrigation structure.

[0030] See Figure 2 and Figure 5 The drainage structure includes a saline-alkali land water suction pipe 2 and a water delivery pipe 3 pre-buried in the saline-alkali land 1. A partition 4 is fixedly installed on the inner wall of the water delivery pipe 3, and the interior of the water delivery pipe 3 is divided into a drainage chamber 5 and a water inlet chamber 6 by the partition 4. The saline-alkali land water suction pipe 2 is an existing technology, which can discharge the brine in the saline-alkali land 1 and reduce the salinity of the soil, so it will not be repeated.

[0031] See Figure 2 、 Figure 3 and Figure 6 The irrigation structure includes a water reservoir 7 opened on the surface of the saline-alkali land 1, and a water supply component. The water supply component includes a water supply pipe 8 buried in the inner wall of the saline-alkali land 1, a spray pipe 9 fixedly installed on the surface of the water supply pipe 8, and a pumping component arranged inside the water reservoir 7. One end of the spray pipe 9 extends to the top of the saline-alkali land 1. The spray pipe 9 can be used to spray irrigation on the surface of the saline-alkali land 1. The sprayed water is used to irrigate the saline-alkali land 1, so that the salt in the soil can be dissolved and penetrate deep into the soil.

[0032] One end of the water supply pipe 8 is connected to the interior of the water inlet chamber 6, one end of the saline-alkali land water suction pipe 2 is connected to the interior of the drainage chamber 5, and one end of the water delivery pipe 3 extends to the interior of the water reservoir 7. In areas with high groundwater levels, the saline-alkali land water suction pipe 2 can be used to absorb moisture in the soil of the saline-alkali land 1 above the saline-alkali land water suction pipe 2 into the saline-alkali land water suction pipe 2 and discharge it into the water reservoir 7 along the drainage chamber 5.

[0033] A gate 16 is provided at the drainage end of the water reservoir 7 , and an overflow groove 17 is provided on the surface of the gate 16 . When there is a lot of water in the water reservoir 7 , the excess water will be discharged from the water reservoir 7 along the overflow groove 17 .

[0034] See Figure 1 and Figure 4 The pumping components include a water pump 10 fixedly installed on the inner wall of the water reservoir 7, a tee pipe 11 fixedly installed at the water outlet end of the water pump 10, and a water inlet pipe 12 and a circulation pipe 13 respectively connected to the tee pipe 11. The circulation pipe 13 is inside the water reservoir 7. The end of the water inlet pipe 12 away from the water pump 10 is connected to the interior of the water inlet chamber 6. Solenoid valves 14 are provided on the surfaces of the water inlet pipe 12 and the circulation pipe 13, and a nozzle 15 is provided on the surface of the circulation pipe 13.

[0035] A saline-alkali improver or neutralizer is added to the water reservoir 7. At this time, the solenoid valve 14 on the surface of the circulation pipe 13 is closed, and the solenoid valve 14 on the surface of the water inlet pipe 12 is opened. The water pump 10 is driven to draw the water and saline-alkali improver in the water reservoir 7 into the water inlet chamber 6, and transport them along the water supply pipe 8 to the spray pipe 9, and spray the saline-alkali land 1, so that the soil of the saline-alkali land 1 can be improved, and the excess water and saline-alkali improver sprayed into the saline-alkali land 1 will be reused by the saline-alkali land suction pipe 2, and then discharged into the water reservoir 7, so that water resources can be recycled and reused, avoiding waste of water resources.

[0036] After the saline-alkali improver is poured into the water reservoir 7, the solenoid valve 14 on the surface of the water inlet pipe 12 is closed, and the solenoid valve 14 on the surface of the circulation pipe 13 is opened. Then, the water pump 10 is driven to work, so that the water in the water reservoir 7 can be pumped into the circulation pipe 13 by the water pump 10, and re-sprayed into the water reservoir 7 along the nozzle 15. The water flow sprayed by the nozzle 15 drives the water in the water reservoir 7 to flow, thereby accelerating the mixing of the saline-alkali improver with the water in the water reservoir 7.

[0037] The interior of the water supply pipe 3 is divided into a drainage chamber 5 and a water inlet chamber 6 by the partition 4. Therefore, the drainage chamber 5 can be used to discharge excess water transported in the saline-alkali land suction pipe 2, and the water pumped in by the water pump 10 can be transported along the interior of the water inlet chamber 6 to the water supply pipe 8, thereby reducing the laying of pipelines and saving costs.

[0038] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited thereto. Any equivalent replacement or change made by a person skilled in the art based on the technical solution and concept of the present invention should be included in the protection scope of the present invention.
