Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic brackets, and in particular to a multi-row and multi-span flexible photovoltaic bracket. Background Art

[0002] At present, flexible photovoltaic brackets are mainly tightened by straightening 2 to 3 steel cables. A large number of photovoltaic panels are installed on the steel cables, which will increase the impact of wind on the photovoltaic panels. When the wind blows, a large number of photovoltaic panels are prone to high-frequency vibration, which in turn causes the photovoltaic panel installation components to loosen and cause the photovoltaic panels to fall off. For this reason, it is necessary to develop multi-row and multi-span flexible photovoltaic brackets with wind resistance.

[0003] The multi-row and multi-span flexible photovoltaic bracket disclosed in Chinese patent CN219780033U is provided with vertical support plates symmetrically on both sides of the photovoltaic frame, and two end holes are opened through the upper and lower ends of the front side of each vertical support plate. The flexible connection component used for the arranged connection of the photovoltaic bracket is connected between two adjacent vertical support plates, thereby improving the wind resistance stability of the bracket.

[0004] The multi-row and multi-span flexible photovoltaic bracket disclosed in Chinese patent CN217469875U has two frames respectively provided with a horizontal support plate and a vertical support plate. The vertical support plates are symmetrically arranged on both sides of the horizontal support plates. Through holes are arranged inside the vertical support plates, and the two ends of the horizontal support plates are respectively inserted into the inside of the through holes. The outside of the vertical support plates is nested at the two ends of the horizontal support plates through butterfly nuts, thereby improving the wind resistance stability of the bracket.

[0005] The multi-row flexible photovoltaic bracket disclosed in Chinese patent CN116404957A has steel strands for arranging photovoltaic panel brackets fixed between the tops of adjacent supporting columns, and a steel strand lifting suspension device corresponding to the number of steel strands for lifting the steel strands is fixed on the top of each supporting column, thereby improving the wind resistance stability of the bracket.

[0006] However, the structural setting of the multi-row flexible photovoltaic bracket disclosed in the above patent is still insufficient to cope with strong winds in harsh environments. Especially when dealing with strong winds in extremely harsh environments, the stability of the multi-row flexible photovoltaic bracket is poor, and it is still difficult to avoid the possibility of photovoltaic panels falling off.
