Problems solved by technology

The storage cost of this product is high, and the efficiency of solar energy utilization is low
[0005] Although there are also DC photovoltaic water pumps without electricity storage on the market, due to the slanting sunlight, the power generation of photovoltaic cell modules is unstable, which makes the water supply pressure of the pump fluctuate greatly, which affects the water output of the DC photovoltaic water pump without electricity storage.

Abstract

The invention discloses a sunflower type electricity-storage-free solar photovoltaic pump. The sunflower type electricity-storage-free solar photovoltaic pump comprises a panel photovoltaic assembly,a two-dimensional sun following device, a controller, a direct current motor and a pump body. The sun following device is composed of a photoelectric sensor for receiving sun light, a tracking mechanism and a processing circuit, and the tracking mechanism and the processing circuit are used for driving the panel photovoltaic assembly to rotate. The tracking mechanism comprises a left height angletracking unit, a right height angle tracking unit and an inclination axis sun azimuth tracking unit, and the two ends of the inclination axis sun azimuth tracking unit are installed on the two heightangle tracking units. The photovoltaic assembly is installed on the inclination axis sun azimuth tracking unit. The two height angle tracking mechanisms interact through a linkage device to improve the work efficiency of the sun following device. An output shaft of the direct current motor is connected with the pump body, electricity generated by the panel photovoltaic assembly drives the direct current motor to rotate through a wire and the controller, and then the direct current motor drives the pump body to pump water.

Description

technical field [0001] The invention relates to the field of solar photovoltaic technology, in particular to solar photovoltaic equipment. Background technique [0002] Solar energy reserves are large, widely distributed, clean and safe. Photovoltaic water pump technology is just such a technology that can make full use of solar energy and does not consume fuel and other organic energy sources. No pollution is conducive to environmental protection and energy saving, and solar photovoltaic cells have long life and low maintenance costs. This technology is widely used in domestic water supply. It has broad application prospects in irrigation and arid areas. Photovoltaic water pumps have many advantages such as no noise, full automation, high reliability, and good adaptability between water supply and evaporation. Various forms of water pumps are energy-consuming products. The electric energy consumed by pump products in the world accounts for about 20% of the total power gen...
