Patent ID: 8624101

Claim:
An adjustable solar power generation apparatus, comprising: a solar power generation unit comprising: a fixed lens unit comprising a fixed barrel and a converging lens configured for converging sunlight, the fixed barrel having a first end and an opposite second end, the fixed barrel comprising a rim surrounding the first end thereof, the converging lens positioned at the second end of the fixed barrel; a movable barrel located inside and threadedly engaged with the fixed barrel, the movable barrel comprising an inner bottom surface facing the converging lens and an outer bottom surface, the inner bottom surface and the outer bottom surface located at opposite sides of a bottom of the movable barrel; a solar cell located on the inner bottom surface for receiving the converged sunlight; and a drive unit located outside the movable barrel and connected to the movable barrel: a base being substantially a cylinder and comprising an upper surface and a lower surface at opposite sides thereof, the upper surface defining a recess, the rim in contact with the upper surface, the drive unit located at the bottom of the recess and driving the movable barrel to move toward or away from the converging lens so as to move the solar cell toward or away from the converging lens to adjust a light intensity of the converged sunlight received by the solar cell, the recess thereby providing a moving space for the movable barrel to move toward or away from the converging lens; and a supporting bar connected to the lower surface of the base.
