Solar power generation is a method of generating electricity by converting sunlight into DC electricity. As demand for radioactive waste and the environmental pollution caused by chemical fuels, the demand for renewable energy has increased by 48% every year since 2002, It is also growing fastest among all energy technologies. In addition, the price is lowered due to technological development and large-scale production, and the support policy of the country is growing.

In recent years, the aging of the solar power industry has been promoted as an alternative to land use and pneumonitis prior to farming, since agriculture and agriculture in rural areas and low-cost imported salt increase agriculture and pneumatic transfer. On the other hand, since the waste farmland and the pneumonite are soft grounds made of muddy and soft material, it is difficult to apply the concrete which is the basis of the existing photovoltaic power generation structure, and when the slope of the forest is sloped, Maintenance is difficult.

Therefore, the basis of the photovoltaic power generation structure installed on the soft ground and the slope is replaced with an anchor and a spiral file which are easy to install, and the patent prior arts corresponding thereto are disclosed in Korean Patent Laid-open No. 10-2017-0089357 (Apr. The supporting structure for supporting the solar cell module is improved on the ground so that the coupling support can be fastened while the spiral strut is penetrated into the ground, so that the support is directly penetrated on the ground without forming holes in the ground, Korean Patent No. 10-1602953 (Feb. 19, 2016) discloses a support structure for a solar cell module, which comprises a spiral lower file fixed to the ground and fixed on the ground, A support for supporting the module support frame, which is coupled to the upper file and to which the flashlight module is mounted; And a height adjusting means for coupling the upper file and the supporting rods to each other so as to adjust the height of the upper file.

However, when the above-mentioned prior arts are examined, the spiral installed on the ground is convenient to install. However, when installed on the soft ground, the solar light structure falls down due to the load of the photovoltaic module and supporting strut, Is oxidized and damaged, or when the ground itself falls or rises, it can not be prepared.

The integral spiral 20 is rotated to adjust the height, 16 so as to be fixed with bolts and nuts so that the threaded projections of the integral spiral 20 are caught by the protruding threads or projections in the horizontal direction to prevent the integral spiral 20 from rotating.

In other words, the first fixing means 40 is formed by separating one plate type having a cavity so that the integral plate 22 is abutted into two plate types, and a horizontally protruding screw thread or a stencil plate is formed as an integral spiral 20 of the integral spiral 20 so as to have the same thickness as the spacing of the threads of the outer peripheral surface and to be caught by projecting threads of the outer peripheral surface of the integral spiral 20 to prevent the integral spiral 20 from rotating.
