Abstract

This application relates to the field of irrigation technology, specifically disclosing a water-saving irrigation and drainage device for farmland, including a buried infiltration body, a water storage tank, a sprinkler assembly, and a surface pumping assembly. The buried infiltration body is installed below the field surface. The water storage tank is connected to both the buried infiltration body and the sprinkler assembly via pipes, and the surface pumping assembly is connected to the pipes connecting the water storage tank and the sprinkler assembly. Compared to existing technologies, this application not only utilizes the buried infiltration body to collect excess groundwater but also treats surface water accumulation through the surface pumping assembly, significantly improving drainage efficiency. Simultaneously, the entire device stores the collected water for irrigation, improving irrigation water efficiency and avoiding water waste. Moreover, the connections between the components are simple and reasonable, making construction relatively easy. A single buried infiltration body can be installed underground independently, eliminating the need for extensive field excavation and reducing construction difficulty.
