Description

Technical Field

[0001] The utility model relates to the field of photovoltaic brackets, in particular to a windproof and earthquake-resistant photovoltaic tracking bracket system. Background Art

[0002] With growing global energy demand and increasing emphasis on renewable energy, solar energy, a clean, renewable energy source, has gained widespread application. As a crucial component of solar power generation systems, photovoltaic tracking systems ensure that photovoltaic panels always face the sun, significantly improving power generation efficiency. However, in practical applications, photovoltaic tracking systems face various challenges, particularly in areas prone to strong winds.

[0003] As disclosed in patent publication number CN215990667U, titled "Wind-resistant reinforcement system for flat single-axis photovoltaic support system," a wind-resistant reinforcement system for a flat single-axis photovoltaic support system is disclosed, comprising a connecting beam, a steel wire rope, and a steel wire rope length adjustment device. The connecting beam is disposed on both sides of the main axis beam on the bottom surface of the photovoltaic panel, between two adjacent transverse support beams, and is fixedly connected to the two adjacent transverse support beams. A steel wire rope length adjustment device for adjusting the length of the steel wire rope is installed on each column. After the steel wire rope is wound around the rope length adjustment device, its first end is fixedly connected to the connecting beam on one side of the main axis beam, and its second end is fixedly connected to the connecting beam on the other side of the main axis beam. This improves the stress state in the flat single-axis photovoltaic support system, reduces concentrated force, and enhances the strength and stability of the flat single-axis photovoltaic support system.

[0004] In summary, the existing photovoltaic tracking bracket system is usually designed as a flat single-axis tracking type. Although the flat single-axis tracking type improves the power generation efficiency, it is easily damaged due to the rigid design of the bracket structure when natural disasters such as strong winds and earthquakes occur, resulting in bracket deformation, damage to the photovoltaic panels, and even failure of the entire system.

[0030] Working process:

[0031] When multiple groups of photovoltaic support mechanisms 1 operate synchronously and normally, due to the precise synchronization of the astronomical algorithm, the connecting rod damping mechanism 2 rotates and adjusts synchronously with the photovoltaic support mechanism 1. When extreme weather and strong winds come, the external photovoltaic support mechanism 1 is more severely affected by the environment than the internal photovoltaic support mechanism 1, resulting in lower rotation synchronization of the photovoltaic support mechanism 1. At this time, the connecting rod damping mechanism 2 distributes the force of the external photovoltaic support mechanism 1 to the internal photovoltaic support mechanism 1, so that the photovoltaic tracking support system shares the force, increases the synchronization of the photovoltaic support mechanism 1, and effectively improves the stability of the photovoltaic support mechanism 1. During the whole process, the connecting rod damping mechanism 2 plays a role in wind resistance and stability.

[0032] The photovoltaic bracket mechanism 1 of this patent can synchronously track the sun to maintain the optimal angle, thereby improving the solar energy absorption efficiency and power generation; this patent optimizes the center of gravity design of the photovoltaic tracking bracket system, and the connecting rod damping mechanism 2 combines multiple groups of photovoltaic bracket mechanisms 1 arranged side by side into an overall structure to ensure that under the action of strong winds, multiple groups of photovoltaic bracket mechanisms 1 can jointly withstand extreme environments and maintain balance, reducing the risk of overturning; this patent achieves the goal of improving power generation efficiency while effectively reducing the impact of natural disasters such as strong winds and earthquakes on the photovoltaic tracking bracket system.
