Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic bracket reinforcement, in particular to a node reinforcement structure of a photovoltaic bracket. Background Art

[0002] In a photovoltaic power generation system, a photovoltaic bracket is a key component for installing photovoltaic panels, and its stability is directly related to the safe operation and power generation efficiency of the entire photovoltaic system. With the wide promotion of photovoltaic power generation technology, the design and construction of photovoltaic brackets have received increasing attention. However, since photovoltaic brackets are usually exposed to outdoor environments and need to withstand the influence of various natural conditions such as wind loads and snow loads, higher requirements are imposed on their structural stability and durability.

[0003] At present, some photovoltaic brackets are adjustable brackets. In this type of adjustable bracket, a polymer material with a square outer and a round inner is filled in the gap between the main shaft and the column ring. The square main shaft is manually rotated within the column ring through a counterweight and a counterweight swing arm. After rotation, it is adjusted to an appropriate angle through an adjusting arm, and the adjusting arm is fixed to an adjusting arm holder connected to the column. This type of adjustable bracket does not consider the unbalanced wind loads on both sides of the main shaft of the photovoltaic panel, ignores the actual existing torque of the main shaft, and the column and the main shaft are movably connected, so the torque of the main shaft cannot be transmitted to the column. When facing wind load effects, it often cannot effectively bear the resulting unbalanced bending moment, which will greatly reduce the structural stability of the photovoltaic bracket and even cause the collapse of the entire bracket system, resulting in economic losses and safety hazards. Summary of the Utility Model
