Technical Field

The invention relates to the field of ecological bionic photovoltaic power generation systems, in particular to a photovoltaic blade supporting mechanism with rotatable tree-shaped branches for photovoltaic power generation.

Background

Photovoltaic power generation supporting mechanism mainly realizes photoelectric conversion through the photovoltaic board, and the power generation system is incorporated into the power networks in suburb photovoltaic power generation field and rural area commonly, and photovoltaic power generation is applied to road illumination more under the urban environment, and present most photovoltaic power generation supporting mechanism simple structure, photovoltaic board are installed on the coplanar through frame construction more, and area is great relatively, and the appearance is not pleasing to the eye, and photoelectric conversion efficiency is low. In order to further expand the applicable scene of photovoltaic power generation and enable a photovoltaic power generation supporting mechanism to have more ornamental value, domestic and foreign companies and mechanisms provide an ecological bionic photovoltaic power generation system, the system combines a photovoltaic power generation system with various bionic trees to form a multipurpose power generation device with various functional combinations, and the most representative works are solar trees (eTrees) researched and developed by Israel Sologic corporation and photovoltaic trees provided by scientific and technological engineering corporation of the eleventh design research institute of electronics in the information industry in China. The solar tree (eTree) is composed of a main trunk, branches and a plurality of photovoltaic panels, can provide power charging, free Wi-Fi and cold water, and the photovoltaic panels are located in different planes, so that the solar tree is high in wind-digging capacity and has high power generation efficiency; the photovoltaic tree mainly comprises a bionic trunk and a large photovoltaic panel array arranged on the crown, the photovoltaic panel array is horizontally arranged, and the photovoltaic tree has a certain difference compared with a solar tree (eTree) in the aspects of wind resistance, attractiveness, photoelectric conversion efficiency and the like although the photovoltaic tree is simple in structure.

Although ecological bionic photovoltaic power generation systems have achieved certain results in recent two years, no matter a solar tree (eTree) or a photovoltaic tree, the spatial pose of blades cannot be adjusted after the system is operated, so that a photovoltaic panel installed on the bionic tree cannot receive sunlight at an optimal angle through posture adjustment, and further optimal power generation efficiency cannot be achieved. In order to improve the photoelectric conversion efficiency, two schemes of photovoltaic day-by-day and photovoltaic panel three-dimensional arrangement can be adopted, namely the photovoltaic panel can be adjusted to face the sunlight through real-time posture, so that the photoelectric conversion efficiency can be improved; the photovoltaic panels are arranged in a three-dimensional mode, photoelectric conversion efficiency is improved mainly by increasing the light receiving area of the photovoltaic panels, and occupied area is saved. However, on the premise that the tree-shaped photovoltaic power generation supporting mechanism has a large light receiving area and strong wind resistance, and the photovoltaic blades can be adjusted to face the sun through postures, the tree-shaped photovoltaic power generation supporting mechanism has lower cost and manufacturing cost, and becomes an engineering problem to be solved urgently.
