[0005] In order to save the time consumed in galvanizing and improve the efficiency of the galvanizing process and production, the present application provides a photovoltaic bracket galvanizing device.

[0006] This application provides a technical solution that adopts the following:

[0007] A photovoltaic bracket galvanizing device comprises a mounting base, a roller group is rotatably connected inside the mounting base, a protective cover is arranged on the surface of the mounting base, a mounting rod is arranged inside the protective cover, a plurality of connecting blocks are sleeved on the mounting rod, and a fastener for locking the connecting block and the mounting rod is arranged on the connecting block; each of the connecting block side walls is provided with a nozzle, each of the nozzles is connected to a conduit, a shunt pipe is arranged on the top end of the protective cover, and the ends of the plurality of conduits facing away from the nozzles are connected to the shunt pipe.

[0008] By adopting the above technical solution, according to the size of the photovoltaic bracket that needs to be galvanized, a suitable number of connecting blocks are selected, and they are adjusted to the appropriate position by sliding on the mounting rod. After the position adjustment is completed, the mounting rod and the connecting block are fixed with fasteners to improve the stability of the nozzle during use and prevent the nozzle from being deflected due to the reaction force generated when the zinc liquid is sprayed out.
