Description

Technical Field

[0001] The utility model relates to the field of salt drainage systems, in particular to a saline-alkali land stratified improved salt drainage system. Background Art

[0002] Saline-alkali land is a type of salt accumulation, which refers to land where the salt contained in the soil affects the normal growth of crops. Saline-alkali soil is formed under certain natural conditions. The essence of its formation is mainly the horizontal and vertical redistribution of various soluble salts on the ground, which causes the salt to gradually accumulate on the soil surface in the salt-accumulating area. After the formation of saline-alkali land, the soil will become compacted, reducing the soil's labor force, which is not conducive to the absorption of nutrients by crops and hinders crop growth. Therefore, it is necessary to effectively manage the saline-alkali land.

[0003] According to the published patent 202121265399.8, a stratified improved salt drainage system for saline-alkali land includes a crop layer, a saline-alkali layer and a salt washing component, wherein the salt washing component includes a water-filtering geotextile, a salt-washing pipe and a water-guiding cotton rope, wherein the water-filtering geotextile has two layers, the salt-washing pipe is arranged between the two layers of the water-filtering geotextile, the water-filtering geotextile is buried between the crop layer and the saline-alkali layer, and there are two water-guiding cotton ropes, the opposite ends of the two water-guiding cotton ropes are respectively connected to the salt-washing pipes, and the opposite ends of the water-guiding cotton ropes are respectively buried in the crop layer and the saline-alkali layer, in order to achieve During the process of the invention, the inventor found that at least the following problems in the prior art have not been solved: the water-filtering geotextile penetrates into the saline-alkali layer, and fresh water is transported into the salt-washing pipe. The water-introducing cotton can introduce fresh water into the crop layer and the saline-alkali layer respectively, which solves the problem of not being able to provide moisture to the crop layer, reduce the salinity of the crop layer, and dissolve the salt in the saline-alkali layer. During use, the traditional saline-alkali land stratification improvement and salt drainage system cannot recycle the salt precipitated in the canal, and cannot recycle the fresh water of the saline-alkali land. The salt drainage system is inefficient in stratifying and improving saline-alkali land. For this reason, it is necessary to design a new technical solution to solve it. Utility Model Content

[0004] The purpose of the utility model is to overcome the shortcomings of the prior art, meet the actual needs, and provide a saline-alkali land stratification improvement and salt drainage system to solve the technical problems that the current saline-alkali land stratification improvement and salt drainage system cannot recycle the salt precipitated in the canal and the evaporated fresh water, and the salt drainage system has low efficiency in stratification improvement of saline-alkali land.

[0005] In order to achieve the purpose of the utility model, the technical solution adopted by the utility model is: designing a stratified improved salt drainage system for saline-alkali land, including a base layer, a groundwater layer is arranged above the base layer, a soil layer is arranged above the groundwater layer, a water channel is opened between the base layer, the groundwater layer and the soil layer, two sides of the water channel are connected with V-shaped water guide plates through two support rods, a transparent arc plate is arranged above the V-shaped water guide plate, and limit plates are arranged on both sides of the transparent arc plate, a drainage pipe is arranged inside the groundwater layer, a water storage tank is arranged at one end of the water channel, a submersible pump is arranged inside the water storage tank, the submersible pump is connected to a water pipe through a water supply pipe, one side of the water pipe is connected to a drip pipe, and both ends of the water pipe are fixedly connected to support columns.

[0006] Preferably, one end of the two support rods is fixedly connected to the inner wall of the water channel, and the other end of the two support rods is fixedly connected to both ends of the V-shaped water guide plate.

[0007] Preferably, both ends of the transparent arc-shaped plate are placed on the upper surface of the limiting plate, and one end of the limiting plate is fixedly connected to the inner wall of the water channel.

[0008] Preferably, one end of the drainage pipe extends to the interior of the water channel, and one end of the V-shaped water guide plate extends to the interior of the water tank.

[0009] Preferably, one end of the water delivery pipe is sealed and connected to the water outlet of the submersible pump, and the other end of the water delivery pipe is sealed and connected to one end of the water guide pipe.

[0010] Preferably, a plurality of the drip pipes are provided and evenly distributed on the water guide pipe, and the plurality of the drip pipes are located above the soil layer.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] The utility model combines a water channel, a V-shaped water guide plate, a transparent curved plate, a drainage pipe, a water storage tank, a submersible pump, a water delivery pipe, a water guide pipe and a drip pipe. When the salt in the soil layer penetrates into the groundwater layer, the drainage pipe will transport the water in the groundwater layer to the water channel. Under the irradiation of sunlight, the water in the water channel will evaporate, so that the salt precipitated in the water channel can be recycled.

[0013] The evaporated water will adhere to the transparent curved plate and then drip onto the V-shaped water guide plate, which will then transport the water to the water storage tank. The submersible pump will then pump the water out and use the water pipe to transport the water to the inside of the water guide pipe. The water pipe will then transport the water to the drip pipe, which will then drip water to the soil to improve its salinity. This way, while recycling salt, it can also recycle fresh water from the saline-alkali land, thereby improving the efficiency of the salt drainage system in stratifying and improving saline-alkali land.
