Solar photovoltaic module tracking device and installing method thereof

The invention relates to a photovoltaic tracker, in particular to a solar photovoltaic module tracking device and an installing method of the solar photovoltaic module tracking device. The solar photovoltaic module tracking device comprises stand columns, a main shaft is arranged between every two adjacent stand columns and provided with a photovoltaic module, every two adjacent main shafts are connected through a connecting shaft, the connecting shafts are fixed to the stand columns, the upper end face of each stand column is a stand column installing face, a through hole is formed in the upper portion of each stand column, and one connecting shaft is arranged in each through hole through a bearing structure. The through holes are formed in the stand columns, the connecting shafts are installed in the through holes through the bearing structures, and after pre-installation, a whole stand column combination is hammered in through a pile driver. The solar photovoltaic module tracking device is convenient to install, simple in structure and capable of reducing field installation difficulty and requirements, the installing method can shorten the installing period and reduce cost, and the technical problems that in the prior art, a photovoltaic module tracker has many components, the installing period is long, field installation is very difficult, and field installation is demanding are solved.
