[0002] my country's marine mudflats are open and unobstructed, with long sunshine hours, and have sufficient photovoltaic power generation resources. However, mudflat photovoltaics are in the harsh and severe corrosive environment of the ocean. The photovoltaic bracket system is subject to corrosion from high chloride ions, scouring by oxygen-rich seawater, strong ultraviolet radiation, and alternating dry and wet erosion. Compared with the dry northwest of my country, the corrosion environment makes steel corrode faster. Traditional hot-dip galvanizing anti-corrosion methods will produce a large amount of zinc salts in the marine mudflat environment and gradually fail. At the same time, photovoltaic brackets are mostly fixed with bolts. The hot-dip galvanizing at the connection between the photovoltaic bracket and the bolts is easily worn, making the photovoltaic bracket and the bolts more easily corroded during use, damaging the photovoltaic bracket and reducing the service life of the photovoltaic bracket.

When the connecting tube 7 connects the support arm 4 to the connecting arm 5, the locking assembly 6 is locked in the support arm 4, and cooperates with the fixation of the connecting tube 7 to further improve the stability of the connection between the support arm 4 and the connecting arm 5, without the need for bolt connection, and can reduce the height of the seaside. The corrosion of chloride ions effectively prevents the bracket from loosening and being damaged during use. The support arm 4 and the connecting arm 5 are respectively provided with a sealing assembly 8 that cooperates with the connecting tube 7. The connection will have a certain degree of wear during use. The sealing assembly 8 can seal the connection between the connecting tube 7 and the support arm 4 and the connecting arm 5, effectively reducing the contact erosion of seawater and air containing chloride ions.
