Solar photovoltaic power generation water-saving irrigation system

Abstract

The invention discloses a solar photovoltaic power generation water-saving irrigation system and relates to the technical field of application of photovoltaic power generation systems. An upper water level limit sensor and a lower water level limit sensor are mounted at the upper water level limit part and the lower water level limit part of a water storage tank respectively and are electrically connected with a wiring control cabinet through wires respectively; the wiring control cabinet is mounted on an upright column at the lower end of a photovoltaic component; the photovoltaic component is electrically connected with the wiring control cabinet through a wire; a solar tracking controller is mounted at the connecting part of the photovoltaic component and the upright column; the lower end of the water storage tank is connected with a submerged pump through a water inlet pipe; the submerged pump is electrically connected with the wiring control cabinet through a wire; one side of the water storage tank is connected with a water pipe through an electric water drain valve; the electric water drain valve is electrically connected with the wiring control cabinet through a wire; the tail end of the water pipe is connected with a radial rotation spraying nozzle. By virtue of the combination of water-saving irrigation and photovoltaic power generation, a great amount of energy is saved, the degree of automation is high, a great amount of labor is saved, and the irrigation effect is better.

Description

Technical field: [0001] The invention relates to the application technical field of a photovoltaic power generation system, in particular to a solar photovoltaic power generation water-saving irrigation system. Background technique: [0002] It is predicted that by 2050, the world's total population will increase from 7 billion to 9 billion, and human demand for food will increase by another 70% to 100% from the current level. The world's fresh water resources are increasingly scarce, and human demand for food is also increasing. Fresh water resources have become a threat to agricultural development and the security of the world's food supply. To solve the problem of limited arable land, shortage of fresh water resources and rising world food demand, the development of water-saving irrigation becomes the key. [0003] Water-saving irrigation is an irrigation measure to obtain the maximum yield or profit with the minimum amount of water, that is, to maximize the crop yield a...
