Solar energy is a clean energy source without pollution, and a solar photovoltaic panel can convert solar energy into electric energy. In order to convert solar energy into electric energy to the greatest extent, in general, a solar photovoltaic panel is arranged on a rotatable vertical support, a solar tracking controller controls a driving system to drive the vertical support to drive a solar photovoltaic panel to rotate, and the solar photovoltaic panel is always irradiated by sunlight after chasing the sunlight. Typically, a large solar photovoltaic power generation base is provided with thousands of solar photovoltaic panels, as shown in fig. 1 and 2, each solar photovoltaic panel 1 is fixed on a rotatable upright 2, and a set of driving devices for driving the solar photovoltaic panels to rotate is mounted on each upright. The driving device comprises a planetary gear motor 3, a worm 4 and a big worm wheel 5 with the diameter of 250 cm. A fixed base 6 is arranged below each upright post 2, the fixed base 6 is fixed on the ground, a big worm wheel 5 with the diameter of 250 cm is arranged on the fixed base 6, and the upright posts 2 are fixedly connected with the big worm wheel 5.
