technical field [0001] The invention relates to a complete machine of a robot photovoltaic power generation unit with a variable focal length focusing lens.

However, the existing lens zoom structure usually realizes the adjustment of the focal length through the combination of multiple lenses overlapping with the displacement mechanism. The stability is also poor, and it cannot be applied to occasions where the axial space is limited, such as solar power generation devices. [0003] Therefore, the exterior of the solar panel in the existing solar power generation device has no optical focusing structure, and only relies on natural light for photovoltai...

Problems solved by technology

[0002] In order to adapt to the change of external light intensity, for example, in rainy weather with low light intensity, the focal length of the condenser lens needs to be reduced, and at noon when the light intensity is relatively strong, the focal length of the condenser lens needs to be increased. However, the existing lens zoom structure usually realizes the adjustment of the focal length through the combination of multiple lenses overlapping with the displacement mechanism. The stability is also poor, and it cannot be applied to occasions with limited axial space, such as solar power generation devices

[0003] Therefore, the exterior of the solar panel in the existing solar power generation device has no optical focusing structure, and only relies on natural light for photovoltaic power generation. In low rainy weather, the efficiency of photovoltaic power generation is very low, and even photovoltaic power generation cannot be carried out. When the intensity of sunlight is relatively strong, the temperature is high, and the sun shines on the solar panel, which makes the temperature rise of the panel too high and shortens the service life of the solar panel
