Description

Elastic limit wire control chasing solar power generation equipment

The present invention relates to an elastic limit wire control sun-type solar power generation device, and particularly relates to a solar power generation device that utilizes a middle column and a wire to control the solar energy recovery function of the solar power generation module.

Usually, the solar power generation system is fixed on the building and cannot be adjusted in accordance with the position of the sun, so that the utilization rate of the solar energy is greatly reduced. Alternatively, a wind-solar hybrid power generation system uses a column supporting a wind power generator to fix a solar power generation module, but the solar power generation module under such a system is usually small. Since the central portion of the solar power module is directly inclined to the column, if the area of the solar power module is too large, it will be destroyed by strong wind because the joint strength between the column and the solar power module is insufficient to resist strong wind. Alternatively, when an external force is suddenly applied to the solar power generation module, the solar power generation module is easily damaged because the rigidity of the solar power generation module is too high. Therefore, there is still room for improvement in conventional solar power generation systems.

On the other hand, when a cable is used in conjunction with an elastic element for control, the elastic element may exceed its elastic limit due to encountering a typhoon, thereby damaging or even destroying the entire solar power plant.

Therefore, an object of the present invention is to provide a solar power generation device that utilizes a center pillar and a wire to control the solar energy recovery function of the solar power generation module, thereby achieving stable elastic support and the effect of chasing the sun.

In order to achieve the above object, the present invention provides an elastic limit wire control chasing solar power generation device, which is mounted on a fixed structure, and the solar power generation device comprises a solar power generation module, a middle column, first and second winding devices.

The first and second winding devices are disposed on or in the center pillar. The first wire has a first end connected to the first corner portion and a second end connected to the first winding device, and the first wire can be wound around the first winding device. The second wire has a first end connected to the second corner portion and a second end connected to the second winding device, and the second wire can be wound around the second winding device. The third wire has a first end connected to the third corner portion and a second end connected to the first winding device, and the third wire can be wound around the first winding device. The fourth wire has a first end connected to the fourth corner portion and a second end connected to the second winding device, and the fourth wire can be wound around the second winding device. The azimuth angle of the solar power generation module is adjusted by rotating one or both of the first winding device and the second winding device. The first to fourth elastic anchor portions are elastically mounted to the fixed structural body and respectively correspond to the first to fourth corner portions, and the first to fourth wires respectively pass through the first to fourth elastic anchor portions to form two A W-shaped structure, one or each of the first to fourth elastic anchor portions includes an elastic member and a limiting member connected in parallel, and the limiting member limits a maximum amount of deformation of the elastic member.
