Description

Technical Field

[0001] The present invention relates to the technical field of saline-alkali land treatment, and in particular to a self-cleaning saline-alkali land concealed pipe-vertical shaft photovoltaic drainage system. Background Art

[0002] It is widely used in the management of large-scale saline-alkali land, among which concealed pipe drainage technology is a widely promoted engineering measure.

[0003] For example, Chinese patent CN115735457B discloses a concealed pipe device for draining salt and reducing alkali in saline-alkali soil, comprising three parts: parallel salt-alkali drainage main pipes, salt-alkali drainage auxiliary pipes arranged between the main pipes, and a micro-power generation device. The salt-alkali drainage main pipes are alternately and evenly spaced with contraction portions and diffusion portions, and the two ends of the salt-alkali drainage auxiliary pipes are respectively connected to the contraction portions of two adjacent salt-alkali drainage main pipes, so that the salt-alkali drainage main pipes and the salt-alkali drainage auxiliary pipes form a square mesh structure, and the salt-alkali drainage main pipes adjacent to each other are connected by the micro-power generation device. The present invention collects salt in the soil by arranging the salt-alkali drainage main pipes and the salt-alkali drainage auxiliary pipes, and discharges the salt into open ditches or artificial wells to achieve soil desalination and improve the soil environment. On the other hand, the flow of water is used to drive the micro-generator through power blades to generate electricity, electrolyze the brackish water, and utilize the electrolysis to collect metal cations and salts in the brackish water, thereby reducing the salt content in the brackish water and gradually improving the soil environment.

[0004] After a long period of drainage, the above structure will cause salt crystallization and sediment precipitation in the pipe. The drainage impact will gradually increase over time, and it cannot be directly cleaned underground, which is not conducive to practical use.
