Description

  The present invention relates to a solar power generation device, and more particularly to a tracking type solar power generation device that performs wire control having an inclined anchor portion.

  Usually, a solar power generation system is fixed on a building, and the direction of solar power cannot be adjusted according to the position of the sun, so the utilization rate of solar energy is greatly reduced. In the wind solar hybrid power generation system, the solar power generation module is fixed by a pillar supporting the wind power generator, but the solar power generation module of this type of system is usually small. Since the central portion of the solar power generation module is tilted and fixed directly to the column, if the area of the solar power generation module is too large, it may be damaged by strong winds. This is because the bonding strength between the column and the solar power generation module is insufficient, so that the strong wind cannot be resisted. Further, when an external force is suddenly applied to the solar power generation module, the solar power generation module is easily destroyed because the rigidity of the solar power generation module is too high. Therefore, the conventional solar power generation system still has room for improvement.

  The inventor disclosed an elastic wire control tracking type solar power generation device according to Taiwan Patent Registration No. M421480, and disclosed a traction control device for a tracking type solar power generation mechanism according to Taiwan Patent Publication No. 2014118646. Both of these two tracking power generators need to be fixed to one fixed structure. The fixing structure is, for example, a steel plate or the ground. If a large steel plate or a cross-shaped steel structure is used as a fixed structure, the cost of the steel material is very high. If the ground is a fixed structure, the ground constructed from concrete must be a fixed structure. In the case of large-scale power generation, none of the above-described inventions can effectively reduce the cost, and if concrete is used, it is necessary to wait for the time for the concrete to harden, which is inappropriate for quick construction. The present invention improves on the above two patents and therefore includes the entire contents of the two patents for reference.
