An intelligent drip irrigation system with solar pumped storage

Abstract

The invention relates to a pumped storage dripping irrigation system, in particular to a solar pumped storage intelligent dripping irrigation system suitable for most well irrigation areas and well-canal irrigation areas. The invention aims to combine solar energy generation and pumped storage to provide water source with relative stable pressure for the dripping irrigation, and provide a pumped storage dripping irrigation system with low dripping irrigation system head loss and high uniformity of irrigation through adopting an advanced sensor and an intelligent automatic control system. The solar pumped storage intelligent dripping irrigation system has the advantages of being environmentally friendly, high in energy-saving and intelligence, low in cost, capable of complying with social development, high in environmental benefits, social benefits and of considerable economic benefits, and comparatively wide in application prospect.

Description

technical field [0001] The invention relates to a pumped-storage drip irrigation system, in particular to an intelligent drip irrigation system of solar energy pumped-storage suitable for most well irrigation areas and well-canal combined irrigation areas. Background technique [0002] my country is a country with an extreme shortage of water resources, and farmland irrigation is a major user of water resources, accounting for about 65% of the country's total water supply. At present, the average annual water use of agricultural irrigation is 360 billion m3, mainly ground irrigation, and the irrigation water use efficiency is only about 0.50. With the large-scale implementation of water-saving irrigation in farmland in my country, in some typical well irrigation areas and well-canal combined irrigation areas (such as the Yellow River irrigation area and the Northeast canal irrigation area), more and more drip irrigation technology is used, which greatly saves water resources...

AI Technical Summary

Problems solved by technology

When additional power is used, on the one hand, the cost of the irrigation system will be increased; on the other hand, the electricity generated by solar photovoltaics during the non-irrigation period cannot be effectively used, resulting in a waste of resources

However, when additional storage equipment is provided for the drip irrigation system, it will be limited by many factors such as battery capacity and environmental pollution, which is not conducive to the sustainable development of photovoltaic power generation irrigation.

[0005] At present, the drip irrigation system has high energy consumption, high operating costs, lack of effective crop water demand signal sensor feedback and intelligent control system, and when solar power is used for agricultural irrigation, there is also a problem that photovoltaic power generation is not synchronized with farmland water demand, and irrigation The guarantee is not high and the utilization efficiency of photovoltaic power generation is low, etc.
