Wind-powered water-pumping irrigation system

Abstract

A wind-powered water-pumping irrigation system comprises a wind power transmission part, a mechanical transmission part, a hydraulic transmission part, and a water storage irrigation part. Blades of the wind power transmission part rotate under the effect of wind power and transmit the wind power to a main shaft of the mechanical transmission part through hubs. The main shaft is a crank rocker mechanism formed by a crank shaft being connected with another output crank shaft through a connecting rod. The main shaft drives the output crank shaft to swing reciprocally. Torsion generated by the wind power is transmitted to an optical shaft at the bottom of a tower frame through a transmission steel pipe. The optical shaft is connected with two steel wire ropes which are respectively connected with two ends of a piston inside a hydraulic cylinder of the hydraulic transmission part. The optical shaft is driven by the output crank shaft to swing so as the enable the piston to move reciprocally up and down. Through reversing of four one-way valves, underground water is pumped into a water storage pool of the water storage irrigation part. The wind-powered water-pumping irrigation system is low in manufacturing cost, simple in structure, capable of saving a generator set which is high in price, simple and convenient to operate, low in failure rate, large in economical benefit and social benefit, and applicable to popularization and use in wide, remote and border areas which are rich in wind energy.

Description

technical field [0001] The invention relates to water storage irrigation technology, in particular to a wind-driven water-lifting irrigation system. Background technique [0002] In our country, agriculture is a basic industry, and grain production is very important. Increasing grain production is a basic national policy, and an important breakthrough for increasing grain production is to further expand the irrigated area. Due to the shortage of energy in remote areas and the inconvenience of erecting power grids, the irrigated area is limited. Further expansion, the vast areas of Northeast, Northwest, and North my country with abundant wind resources, the development of wind power water pumping irrigation is an important way to develop agricultural production in these areas. Existing wind power water lifter has two kinds, and a kind of is to lift water by energy conversion wind power, promptly by air compressed air power transmission power or by electric power generation ele...

AI Technical Summary

Problems solved by technology

There are two types of existing wind-powered water lifters. One is to lift water by wind power through energy conversion, that is, to drive power through air compression or power transmission through electric power generation. Among them, air compression transmission has low transmission efficiency and is not suitable for promotion.

Wind power generation requires equipment such as gear transmission behind the windmill, generator, control device and grid connection, and the high cost is difficult to promote

The other is the mechanical wind-powered water lifter, which is composed of two functional parts: a windmill and a water-lifting pump. The water-lifting pump generally adopts a reciprocating pump, so that the efficiency of the wind-powered water lifter is not high, the flow rate is small, and the head is low.

Many key issues (such as high-efficiency wind rotor design, high-efficiency matching of fans and water pumps) have not been well resolved, and a large-scale market has not yet formed
