Description

Technical Field

[0001] The utility model relates to the technical field of lightning protection devices, and more specifically, to a lightning protection device for a photovoltaic power station. Background Art

[0002] A photovoltaic power station lightning protection device is a device used to protect photovoltaic power station equipment from lightning strikes or lightning. It usually includes components such as lightning rods, lightning strips, and lightning nets. It is designed to guide lightning underground or away from photovoltaic power station equipment to prevent lightning strikes from damaging the equipment. This device is designed to improve the stability and reliability of the photovoltaic power station system and ensure that the solar power generation system can operate normally without being affected during lightning weather. The fixed height of the lightning protection device causes great inconvenience in repairing and replacing lightning rods. Since the height cannot be adjusted, additional measures need to be taken to deal with height mismatches when repairing or replacing lightning rods, which increases the complexity and difficulty of the operation.

[0003] The bottom of the existing lightning rod is supported and fixed by a bracket to prevent it from tipping over. Since the lightning rod is installed at a high position, it needs to be supported by a straight rod, which results in a longer straight rod. When fixing the straight rod, it usually requires multiple people to work together to straighten the straight rod, and then connect and fix the bottom of the straight rod to the connecting frame. This installation method requires more manpower and is inconvenient to operate.

[0004] After parts are damaged, existing devices have the problem of inconvenient disassembly and maintenance. Due to design or structural limitations, damaged parts may be difficult to disassemble easily, requiring more time and labor to repair or replace, which brings certain troubles to maintenance work.
