Abstract

An automatic tracking solar energy collection device based on piezoelectric drive, including a structural support, a triangular support mechanism is connected below the structural support, a solar collection plate and a solar azimuth measuring disc are connected above the structural support, and the signal output of the solar azimuth measuring disc is transmitted to three A top-to-top linear piezoelectric drive attitude adjustment mechanism, through which the solar collector plate and the sun are aligned; the invention has the advantages of higher tracking accuracy and higher conversion efficiency.

Description

technical field [0001] The invention relates to the field of solar power generation, in particular to a piezo-driven automatic tracking solar collector. Background technique [0002] With the development of modern industry, human beings have higher and higher demand for energy, while traditional energy such as petroleum, coal and other fossil fuels have limited reserves, and the use of them will cause serious environmental pollution. Therefore, the development of green energy has important epochal significance . As one of the most common green energy sources, solar energy itself has the advantages of "unlimited" reserve characteristics, universality, and cleanliness. However, because solar energy is a low-density, intermittent, and spatially changing energy source, the maximization of solar energy collection has become a research focus and hotspot. At present, there are a large part of solar energy equipment on the market, such as solar water heaters, solar cells, etc., bu...
