Description

Self-adaptive photovoltaic support with intelligent light following and active wind shielding functions

Technical Field

The utility model relates to a photovoltaic field, more specifically relates to a self-adaptation photovoltaic support with intelligence is followed spot, is initiatively kept away wind function.

Background

At present, a fixed photovoltaic bracket is mostly adopted by the photovoltaic bracket, the bracket requires that the best installation inclination angle is calculated in advance by combining the conditions of local geographic environment, climate and the like at the beginning of design, and the calculation needs to refer to the climate data of local calendar year. According to the inclination angle setting situation, the method can be divided into the following steps: fixed type of optimum dip angle, fixed type of pitched roof and fixed type of adjustable dip angle.

The optimal inclination angle fixing type is that the local optimal installation inclination angle is calculated firstly, and then all the arrays are fixedly installed by adopting the inclination angle, so that the optimal inclination angle fixing type is widely used in flat roof power stations at present. The flat roof-concrete foundation support is the most common installation form in the existing flat roof power station, the support needs to be manufactured with a concrete foundation first and maintained to be strong enough to carry out subsequent support installation, and the application period is long. The wind resistance of the plane roof-concrete ballast support is relatively poor, and the maximum local wind power needs to be fully considered when the weight of the counterweight is designed. The ground power station-metal pile support is widely applied to the ground power station, and has the defects that pile driving is difficult in hard soil areas, pile driving is easy to damage a zinc coating in areas containing more broken stones, and the corrosion resistance is poor when the ground power station-metal pile support is used in saline-alkali areas.

The fixed bearing capacity of the inclined roof is poor, most of components on the inclined roof are directly tiled and installed, and the azimuth angle and the inclination angle of the components are generally consistent with those of the roof.

The fixed type with the adjustable inclination angle refers to that the inclination angle of the fixed type support is adjusted periodically at the turning point of the change of the solar incident angle, so that the direct sunlight absorption is increased, and the irregular adjustment mode has larger workload.

At present, a fixed photovoltaic support is basically adopted, the inclination angle of the photovoltaic support is fixed at a certain angle, the support does not have any function of adjusting the inclination angle, the support passively receives natural irradiation of the sun, the sunlight utilization rate is poor, the power generation amount is small, and the yield is low.
