Description

Photovoltaic tracking installation structure

technical field

The invention relates to the field of photovoltaics, in particular to a photovoltaic tracking installation structure.

Background technique

The current solar tracking bracket is driven by a worm gear (also known as a reducer), and a worm gear is used to limit the position, but the whole bracket is always in a single-point stress state by using a worm gear and worm, so this installation structure will lead to stress. Concentrated on the point of force, and secondly, in the case of long-term single-point force, the worm gear is easily damaged by fatigue, or directly damaged in strong wind conditions. Although electric push rods or gears are currently used instead of worm gears for installation, the use of electric push rods or gears still has the same defects as worm gear installations.

The life of the reducer reduces the probability of damage; when extreme weather occurs, the external force load exceeds the design conditions, and the damping rod bears the damage load to protect the reducer. The cost of the damping rod is 5%-10% of the reducer, which can Reduce maintenance costs; and because the torsional load is shared by the damping rod and the main beam, the design cross-sectional area of the main beam is reduced, and the construction cost is saved.
