Power generation technologies that utilize solar energy to produce electricity include solar power generation that uses solar heat to drive a heat engine to generate electricity, and solar power that generates electricity from solar cells using solar light.

Here, a solar cell used for solar power generation includes a semiconductor compound element that converts sunlight directly into electricity.

As the solar cell used for the photovoltaic power generation, usually silicon and a composite material are usually used. Specifically, a solar cell uses a P-type semiconductor and an N-type semiconductor in combination, and utilizes a photoelectric effect to generate electricity by receiving sunlight.

Then, the wedge member 220 is inserted into the wedge member groove 135 on the bottom surface of the second support unit 130, and the bottom surface of the second support unit 130 is coupled to the coupling plate 210. .

Therefore, even if the fastener 240 is spaced apart from or removed from the wedge member 220, the wedge member 220 is prevented from being separated from the wedge member groove 135, so that the fastening 240 is coupled with the rotation shaft 146. have.

This increases safety of the coupling between the power transmission unit 140 and the second support unit 130 through the removal prevention unit 200, and thus more safety of the components disposed above the second support unit 130. Strong support is expected.

In addition, by improving the coupling structure of the support frame 110, the assemblability according to the scale is increased, and also has the effect of complementing the rigidity of the support frame 110.

While the present invention has been described with reference to exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims. Therefore, the true technical protection scope of the present invention will be defined by the technical spirit of the appended claims.
