Abstract

The invention relates to a dual-shaft support structure of concentration photovoltaic panel, comprising a vertical rotation shaft and a pitching rotation shaft; a vertical rotation shaft driving mechanism is arranged in a cavity column; a vertical rotation shaft is provided with a horizontal support disk; the horizontal support disk is provided with the pitching rotation shaft and a driving mechanism of the pitching rotation shaft; a worm shaft of a turbine worm reducer of a pitching rotation shaft driving mechanism is connected with a universal joint; one end of a driving arm is connected with a shaft of the universal joint; and the other end of the driving arm is connected with a driving disk of the pitching rotation shaft. A main support frame for supporting the concentration photovoltaic panel is fixed on two ends of the pitching rotation shaft; and the main support frame is provided with an upper support frame. The dual-shaft support structure of concentration photovoltaic panel has the outstanding advantages that the structure is simple and compact, the manufacturing cost is low, the controlling is reliable and the precision is high.

Description

technical field [0001] The invention belongs to solar energy receiving equipment, in particular to a biaxial support structure of a concentrated photovoltaic panel. Background technique [0002] Concentrating photovoltaic panels are composed of particulate gallium arsenide cells, Fernier lenses and supports, and are a new generation of solar power generation technology with high conversion efficiency. In solar power generation equipment using concentrating photovoltaic panels, a dual-axis support structure composed of a vertical rotation axis and a pitching rotation axis is commonly used. It is to make the concentrated photovoltaic panel track the change of the sun's altitude angle. [0003] In the existing technology of dual-axis support structure, the vertical shaft and the pitch shaft are respectively driven by the motor and its reducer, but the connection structure between the vertical shaft and the pitch shaft and the bracket on which the concentrated photovoltaic pane...
