The invention relates to a photovoltaic blade, comprising: a rotating shaft; a photovoltaic plate arranged on the rotating shaft, and capable of rotating around the rotating shaft, and driving the rotating shaft to rotate when rotating, wherein, a photoelectric conversion unit is arranged on the photovoltaic plate; a power generation unit connected with the rotating shaft, and used for convertingthe energy of the photovoltaic plate driving the rotating shaft to electric energy. According to an embodiment of the present invention, As the photovoltaic plate can drive the rotate shaft to rotatewhen the photovoltaic plate rotates, and the power generation unit can convert the energy that the photovoltaic plate can drive the rotating shaft to rotate when the photovoltaic plate is rotated intoelectric energy, so that when the photovoltaic plate is subjected to a force other than the rotating shaft, for example, wind force, the energy generated by the force can be converted into electric energy instead of being accumulated into potential energy that bends photovoltaic plate, thereby avoiding damage to the photovoltaic plate.
Description
technical field [0001] The invention relates to the field of optoelectronic technology, in particular to a photovoltaic blade, a photovoltaic power generation device and a control method of the photovoltaic blade. Background technique [0002] In order to improve the power generation efficiency of the photovoltaic power generation device, the photovoltaic power generation device is generally placed in an open area without obstacles to block the light. However, the wind in the open area is generally large, and the photovoltaic blades in the current photovoltaic power generation devices are mostly fixed, which causes the photovoltaic blades in the photovoltaic power generation device to withstand large wind power, which is easy to cause damage to the photovoltaic blades. SUMMARY OF THE INVENTION [0003] The present invention provides a photovoltaic blade, a photovoltaic power generation device and a control method for the photovoltaic blade, so as to solve the deficiencies ...
