For the suspension cable supporting flexible support in the existing market, the two ends and the middle of the suspension cable are mostly fixed with the upper support, and then the photovoltaic module is fixed on the suspension cable to form the photovoltaic power generation support with the fixed photovoltaic module inclination angle. However, as the land for photovoltaic, especially better light resource land, is less and less, the cost of land cost in the investment of the photovoltaic power station is higher and higher, and the demand of high return rate of limited land and shortened cost recovery period follows.
For the photovoltaic module, the power generation efficiency is related to the sunlight incidence angle, and the closer to the vertical irradiation (90 degrees), the higher the power generation efficiency, so according to the characteristic, the best solution for improving the power generation efficiency of the photovoltaic module is to adjust the inclination angle of the photovoltaic module.
The prior inclination angle adjusting device for the flexible photovoltaic support generally adopts a hinged mode to realize inclination angle adjustment of a photovoltaic module, and the inclination angle adjusting device does not consider the exaggerated pretightening force and the huge bending moment brought to the inclination angle adjusting device by the internal force of the suspension cable, so that a structural part connected with the suspension cable is easily bent and the hinged part is easily broken. Meanwhile, in the inclination angle adjusting process, the internal force of the suspension cable changes constantly, and the instability risk of the inclination angle adjusting device is further aggravated. The invention provides an inclination angle adjusting device and a flexible photovoltaic support to solve the technical problem.
