Desert irrigation and sand control technique by natural-energy power generation

Abstract

The invention relates to a novel technique capable of electrically irrigating and sprinkling deserts on site by power generated from natural wind energy or solar energy. The novel technique comprises a power generation system and a pumping and irrigating system. The power generation system comprises a wind-energy or solar power generator 1 and a variable-frequency voltage regulator 2. The pumping and irrigating system comprises an accumulator 3, a water pump 4, a temperature sensor 18, an electric-heating thermal insulation pool 5, a sprinkling irrigation device 6, an antifreeze water pipe 17 and an antifreeze sprinkling irrigation valve 16. Power generated by the wind energy or solar power generator 1 through natural wind energy or solar energy is regulated by the variable-frequency voltage regulator 2 to output a voltage-stabilized power supply (220V-230V) to drive the water pump 4 of the pumping and irrigating system to pump water, the underground water pumped all day long is irrigated to the desert surfaces by the irrigating device 6 through the temperature sensor 18 and the antifreeze water pipe 17 sequentially. The novel technique has the advantages of stabilizing sand to realize environmental protection, changing climatic environments of deserts, forming earth surface water and soil protection and functioning in ecological virtuous cycle, and is environment friendly, clean and low in cost.

Description

technical field [0001] The invention belongs to a sand control project in the field of sand control and protection of natural environment, and specifically relates to a desert sand control technology using natural energy to generate electricity for irrigation. Background technique [0002] So far, several large desert freshwater lakes in China, such as Lop Nur in the Taklamakan Desert in Xinjiang, have long since dried up and disappeared. The remaining Hongjiannao freshwater lake is also facing a trend of shrinking year by year. In addition, the current sandstorm in Beijing and Tianjin has not been eliminated. signs. [0003] In order to eliminate or reduce the losses caused by deserts to human beings as early as possible, a major sand control engineering technology is needed to suppress and transform them. Contents of the invention [0004] The purpose of the technology of the present invention is to use natural energy (wind energy or solar energy) to generate electricit...
