The invention provides a light-sensing tracking control mechanism suitable for a single axis photovoltaic panel tracking device and simple in structure and low in cost. A limiting mechanism is installed on a low vertical column of the single axis photovoltaic panel tracking device, and a grating groove is also installed on the inner side of a high vertical column. In the limiting mechanism, a position detecting head is installed below a rotating shaft, the position detecting head penetrates into two travel switches, the two travel switches are a first travel switch and a second travel switch,the two travel switches are respectively installed on a first bracket and a second bracket, the two brackets are installed on a bracket of the limit mechanism, and the two brackets have adjustable tilt angles. The position detecting angle of the position detecting head when touching the first travel switch and when touching the second travel switch is 90 degrees to 120 degrees. A photosensitive element is installed at the bottom end of the grating groove in the high vertical column.
Description
technical field [0001] The invention relates to the field of photovoltaic power generation, and is specifically applied to controlling a single-axis photovoltaic panel tracking device to track the sun. Background technique [0002] At present, the single-axis sun tracking device generally sets the motor to rotate once every certain time for cost considerations, and the photovoltaic panel returns to the same position every day, and then restarts the next day; this setting makes the motor in the whole system rotate The rotation frequency is high, but its tracking process is relatively lagging, and it cannot track the sun's trajectory well, and the power generation efficiency is affected. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a light-sensing tracking control mechanism suitable for a single-axis photovoltaic panel tracking device with a simple structure and low cost. [0004] The technical solution adopted...
