Description

Flexible drive solar tracking system with damping mechanism

technical field

The invention relates to the field of photovoltaic supports, and further relates to a flexible driving solar tracking system with a damping mechanism.

Background technique

Photovoltaic tracking bracket is a common tracking device in the field of solar photovoltaic power generation. It can adjust the angle of the solar panel so that the solar panel is exposed to the front of the sun at any time of the day to improve power generation efficiency.

At present, the photovoltaic tracking brackets on the market have many ways to adjust the angle of the solar panel, and adjusting the rotation of the solar panel through the movement of the pulling rope is one of the many ways. For example, the Chinese utility model patent with application number 202021629273.X (flat single-axis solar tracking bracket and tracking system with single drive belt and multiple rotations) adjusts the angle of the solar module by pulling the traction rope. The Chinese utility model patent (solar tracking system) with application number 202120676928.7 adjusts the angle of the solar panel through the main rope.

It should be pointed out that the photovoltaic support is usually installed in an open-air environment, and it is inevitable to encounter severe weather such as strong winds in the open-air environment. When the cable is too long, the expansion and contraction of the cable due to its own gravity sagging and its own elasticity cannot be ignored. In severe weather environments such as strong winds, the cable will inevitably be tensed and loosened with the wind, which will drive the photovoltaic support. The large shaking will affect the stability of the tracking system.

To sum up, it is necessary to improve the existing photovoltaic tracking brackets.
