Description
Technical Field

Background
Compared with a traditional fixed photovoltaic support, the tracking photovoltaic support has the advantages that the time for the component to face the sun is more, the received sunlight illumination is more sufficient, and the power generation efficiency is remarkably improved.
The tracking photovoltaic support is mainly divided into horizontal single-axis tracking and double-axis tracking, and the difference between the horizontal single-axis tracking and the double-axis tracking is that the horizontal single-axis tracking and the double-axis tracking are used for tracking the east-west direction of the sun in the east-rising-west-falling direction only. The double-axis tracking is to track in two directions, namely, the tracking in an east-west direction and the tracking in a north-south direction with different sun altitude angles along with different seasons. The effect of the tracking in the north-south direction is more obvious along with the higher latitude. Therefore, compared with the flat single-axis tracking, the double-axis tracking has the remarkable improvement of the generating capacity.

In the prior art, in order to reduce the shielding of the main beam on the photovoltaic module on the secondary beam and increase the solar energy received by the photovoltaic module, the photovoltaic module is usually arranged above the main beam. If the height position of the secondary cross beam and the photovoltaic module is only improved, the gravity center of the whole structure can be improved, the main cross beam can be subjected to a large torque, and meanwhile, the stand column bears a large bending moment, so that the whole power generation device is unstable.

The mass of the rotating mechanism is mainly concentrated on the photovoltaic module, the photovoltaic module is arranged above the main beam, the gravity center of the rotating mechanism is higher than the rotation axis center of the main beam, namely higher than the rotation axis center of the rotating mechanism, when the main beam rotates along the rotation axis center of the main beam, the main beam drives the rotating mechanism to deflect, and the gravity center of the rotating mechanism deviates from the position right above the upright post supporting point. The gravity center shift can form certain bending moment on the upright post, and when the bearing force of the upright post is too large, the collapse of the device can even be caused, so that serious accidents are caused.
In order to reduce the influence of center of gravity shift, in the prior art, a secondary cross beam is generally required to be arranged below a main cross beam, the main cross beam is connected with the secondary cross beam through a specially designed connecting structure, then an assembly supporting structure is arranged on the secondary cross beam, the bottom end of the supporting structure is lower than the main cross beam, the top of the supporting structure is higher than the main cross beam, finally a photovoltaic assembly is arranged on the supporting structure, and the center of gravity of a rotating mechanism is adjusted to be right above a stand column supporting point by arranging the secondary cross beam into a counterweight form.
