Description

TECHNICAL FIELD

[0001] The present application relates to the field of photovoltaic power generation devices, and in particular to a foldable photovoltaic carport. BACKGROUND

[0002] With the widespread use of renewable energy, many highway toll station carport roofs have adopted photovoltaic panels to generate electricity from solar energy to provide clean energy for the toll station. However, in southern coastal cities, this kind of photovoltaic carport faces a significant problem: typhoon weather. Typhoons in these areas are frequent and strong, and traditional fixed photovoltaic roofs are easily damaged or even collapsed in typhoon weather, causing economic losses and safety hazards.

[0003] Existing photovoltaic carports at highway toll stations are usually composed of several fixed photovoltaic panels spliced together and installed on the top of the carport through a steel frame structure. This fixed structure can effectively collect solar energy under normal weather conditions, but in the face of typhoons, due to the large area of photovoltaic panels and the inability to fold or adjust the angle, it is easily impacted by strong winds. Strong winds not only damage the photovoltaic panels themselves, but also can cause serious damage to the entire steel frame structure, causing the photovoltaic panels to collapse and even posing a threat to passing vehicles and pedestrians.

[0004] In addition, even after the typhoon weather, the damaged photovoltaic panels and steel frame structure need to be repaired and replaced, which not only increases the operating costs of the toll station, but also can affect the normal toll collection work. Therefore, how to design a photovoltaic carport that can adapt to typhoon weather, so that it can automatically fold or adjust the angle under strong wind conditions to reduce wind pressure and wind resistance, has become a problem to be solved.
