In Northwest China, the rainfall is low and the climate is dry, but the groundwater is shallow, the wind resources are abundant. It has social and environmental benefits to take wind power as the driving force, extracting groundwater to irrigate and rehabilitating degraded natural ecosystems. This paper briefly describes the development history of wind water pumping in China, analyzes the problems existing in the selected wind water pumping machines, and makes some improvements. Taking the Hailiutu ranch in the Middle Banner of Inner Mongolia as an experimental site, the groundwater reserves are estimated by drilling data, and the geological conditions of the site are determined. According to the annual rainfall, sunshine, daily mean wind speed, groundwater migration and evaporation, the energy of the available wind energy is calculated and the quantity of the water pumping unit is determined according to the annual water requirement of the site. According to the location of the experimental site, a reasonable overview scheme has been worked out, and a set of irrigation system has been designed, and its feasibility has been analyzed. The test of a single set of equipment shows that the scheme is feasible. The system uses natural energy, one investment and permanent income, so it has good prospects for popularization and application.
