A foldable dual-axis light-following solar cell support

Abstract

The invention discloses a foldable dual-axis sun tracking solar cell support comprising a base rod, a vertical axis steering mechanism, a horizontal axis steering mechanism and a foldable unfolding plate mechanism. The unfolding plate mechanism comprises a fixed frame, a primary unfolding frame and a multi-link transmission mechanism. The multi-link transmission mechanism comprises a worm and gearreduction motor, a driving crank, a first connecting rod, a second connecting rod and a third connecting rod. The worm and gear reduction motor drives the first connecting rod through the driving crank so as to drive opening and closing of the secondary unfolding frame through the second connecting rod and the third connecting rod. The foldable dual-axis sun tracking solar cell support has an unfolding and folding function so that the support can be folded to reduce windward area in inclement weather, and the center of mass of the support changes little in the folded and unfolded state to reduce the torsional moment of the rotating shaft.

Description

technical field [0001] The invention relates to the field of solar battery supports, in particular to a foldable dual-axis light-following solar battery support. Background technique [0002] There are four main structures of solar battery brackets, which are fixed non-adjustable structure, fixed adjustable structure, single-axis light tracking structure, and dual-axis light tracking structure. After experiments and research, compared with fixed The power generation of the type bracket increases by more than 30%, so the significance of the solar battery bracket with dual-axis light tracking is very great. At present, the most common ones are fixed adjustable and fixed non-adjustable brackets. This kind of bracket has high rigidity, simple structure and low cost. The solar cell support with dual-axis light tracking generally uses two orthogonal axes as the rotation axes to provide rotation, one of which is in the vertical direction and the other is in the horizontal directio...

AI Technical Summary

Problems solved by technology

[0003] Dual-axis light tracking solar battery brackets are not common, the main reason is that the structure is more complex, the stiffness is lower than that of fixed brackets, and the cost is much higher than that of fixed brackets; it is easy to be damaged in severe weather such as strong wind and snow

The appearance of the foldable solar cell support enables the support to be folded back under severe weather conditions to protect the device from being destroyed, but there are certain problems in the folding mechanism of the existing foldable frame that greatly reduce the rigidity of the support, such as the folded state and The shift in the center of mass of the solar cell frame in the deployed state places additional torsional stress on the device

In addition, the rotation self-locking of some small dual-axis follower brackets relies on the self-locking of the motor itself, which also makes the device easy to damage
