Solar water pumping device

Abstract

The invention provides a solar water pumping device which comprises a rack, a power storage and supply assembly, a photovoltaic panel assembly and a flexible shaft pump assembly. The solar water pumping device provided by the invention overcomes the defects of long power grid transmission distance, high investment cost of power supply equipment and the like, and achieves the purposes of taking solar photovoltaic power generation as water pumping energy and pumping water on site. When being used for irrigation, the solar water pumping device has positive significance for reducing the irrigation operation cost and the irrigation equipment engineering investment cost, and has more pertinence and practicability for irrigation of remote fields which are not suitable for large-scale irrigation equipment. The effect of supplying water to farmlands, pasturing fields, forests and grassland, farmhouses and courtyards without power supply of a power grid is achieved.

Description

technical field [0001] The invention belongs to the technical field of solar energy, in particular to a solar water pumping device. Background technique [0002] At present, farmlands, pasture fields, forests and grasslands, farmhouses, courtyards, etc. use commercial grids to supply power to water pumps for pumping or irrigating, often due to location constraints, long transmission distances from the grid and high investment costs for power supply equipment, making fields or forests and grasslands The current situation of poor irrigation conditions cannot be improved for a long time. Existing solar water pumping devices have shortcomings such as fragmented structure, voltage level, and DC / AC conversion. If a solar energy pump can be invented to achieve the purpose of pumping or irrigating water without AC / DC conversion, it will have a great impact on pumping water. Or irrigation energy saving and lower pumping or irrigation costs have positive significance. Contents of t...
