The invention relates to a large-power soft-driving
pitch tracking three-dimensional
solar light collecting device which consists of a solar panel, a
speed reduction box body, a support base, motors, a
spur gear, a worm rod, a worm wheel, a vertical driving shaft, a small driving
spur gear, a large driving
spur gear, a circular connecting
pipe, a horizontal driving shaft, a
control system circuit board and a
pitch tracking driving mechanism, wherein the
pitch tracking driving mechanism is arranged outside the
speed reduction box body and connected with the horizontal driving shaft. The large-power soft-driving pitch tracking three-dimensional
solar light collecting device can drive the solar panel to track the sun light in the horizontal and the vertical directions by two motors through the mechanical driving mechanism which comprises the vertical driving shaft, the horizontal driving shaft, the worm wheel, the worm rod, the spur gear and the like, and can be used for driving the solar panel of the
solar street light to realize the automatic tracking of the
solar light collection.
