A wind pumping system

Abstract

The invention discloses a wind-power water pumping system. The wind-power water pumping system comprises a machine frame, a pull rod, a piston, a cylinder body and a wind power conversion mechanism, and is characterized in that the wind power conversion mechanism is composed of a bottom plate, a rotating shaft, a first oil cylinder and / or a second oil cylinder, a telescopic rod, an impeller and a wind power adjusting mechanism; the rotating shaft is arranged on the rotatable bottom plate; the lower end of the telescopic rod is fixed to the first oil cylinder; the pull rod is connected with the upper end of the telescopic rod; and the wind power adjusting mechanism adjusts the telescopic length of the telescopic rod according to the current wind speed so as to control the water pumping frequency and the stroke of the pull rod. According to the wind-power water pumping system, when the external wind speed is low, the stretching length of the telescopic is small, when the wind speed is high, the stretching length of the telescopic is large, and the pull rod conducts water pumping operation at the large stroke and the high speed; and as the magnitude and the speed, formed through water pumping, of the reacting force forces the speed of the impeller to be stable relatively, the piston at the lower end of the pull rod can move up and down in a reciprocating mode at the relatively stable speed regardless of the magnitude of the wind speed, and steady water pumping operation is conducted.

Description

technical field [0001] The present invention relates to a wind-driven water pumping system, in particular to a wind-powered water pumping system which can automatically adjust the pumping speed according to the magnitude of the wind force. Background technique [0002] Wind energy is not only available everywhere, but also has huge reserves, which can be described as inexhaustible energy. Water is a necessary condition for the growth of animals and plants. The normal growth of animals and plants can only be guaranteed if drinking water for animals is guaranteed and plants are fully irrigated. However, in some areas, the growth of plants still has the situation of "depending on the sky". For example, in the vast northwest grasslands of China, grazing is the way of life of local nomadic peoples. Due to the vast area of ​​grasslands, many places have neither built irrigation facilities nor With electricity, the grassland cannot be irrigated in the dry season, and the water nee...

Problems solved by technology

At present, there are systems that use wind energy to generate electricity and then use electricity to pump water. This system has low utilization rate of wind energy, unstable current and voltage, and has disadvantages of large investment and easy damage to electrical components.

There may also be mechanical energy that directly converts wind energy into pumping water. The pumping frequency is slow when the wind is small, and the pumping frequency is fast when the wind is strong. The frequency is very high, which can easily cause mechanical damage
