Sun tracing device

Abstract

A sun tracing device includes a power unit having an elevating element, a supporting plate carrying a photoelectric transformation unit, and an adjusting unit coupled to the power unit and the supporting plate. The power unit is used to lift / lower the adjusting unit, so that the adjusting unit can rotate and / or lift / lower the supporting plate.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This Non-provisional application claims priority under 35 U.S.C. §119(a) on Patent Application No(s). 097135137 filed in Taiwan, Republic of China on Sep. 12, 2008, the entire contents of which are hereby incorporated by reference.BACKGROUND OF THE INVENTION[0002]1. Field of Invention[0003]The present invention relates to a sun tracing device that can automatically return a risen solar panel back by a weight instead of extra forces.[0004]2. Related Art[0005]As the global warming is getting serious, an industry, especially the solar energy industry, based on environment protection and energy saving has become popular. Since the solar energy industry shares similar materials and manufacturing properties with the matured semiconductor and panel industries, it has become the first choice for the high-tech companies that are interested in environment protection and energy saving, and have sufficient technology and human resources.[0006]Other t...

AI Technical Summary

Benefits of technology

[0009]In view of the foregoing, the present invention is to provide a sun tracing device, on which a solar panel can more accurately aim at the sun by an adjusting movement such as a rough adjustment (lifting / lowering) and a fine adjustment (rotating and / or slightly lifting / lowering).

[0010]The present invention is also to provide a sun tracing device including a photoelectric transformation unit. The sun tracing device of the present invention can be returned to an initial state from a rising state so as to effectively reduce the energy consumed by the sun tracing device, hence increase the overall electro-optic conversion efficiency of the photoelectric transformation unit.

[0013]The power unit is further connected to a containing unit substantially, and the power unit and the containing unit contain a fluid flowing between the power unit and the containing unit. Moreover, the power unit and / or the containing unit are further connected to an external power unit, so as to provide the power for driving the fluid from the containing unit to the power unit. Therefore, after the external power unit drives the fluid from the containing unit to the power unit, the fluid would have a higher energy. At this time, the weight of the sun tracing device may be transferred to a fluid with a higher energy by the elevating element of the power unit (e.g. led by the weight of the supporting plate, the solar panel, or other structures), so that the fluid can automatically flow back to the containing unit under the weight effect of the sun tracing device.

[0014]As described above, a sun tracing device of the present invention is used to lift or lower the height of the adjusting unit by the power unit, and is used to finely adjust the tilt angle of the supporting plate by the adjusting unit. For the energy conversion is performed by the flowing of the fluid, the sun tracing device can be returned to the initial state automatically by its own weight; thus, no extra force for the sun tracing device is needed in the sun tracing process. In addition, the sun tracing device of the present invention can be directionally adjusted according to the moving speed and the angle variation of the sun. Compared to the prior art, the sun tracing device of the present invention can gradually return the lifted power unit back to the initial position by its own weight effect (e.g. the weight of the supporting plate, solar panel, or other structures for pressing the power unit), such that no extra force have to be applied, hence the energy can be saved and the solar cell can accurately aim at the sun.

Problems solved by technology

Other than the limitation of the materials used by the solar system, the solar energy can be easily restricted for its own properties.
