Description

Technical Field

[0001] The utility model relates to a photovoltaic light-chasing swing rod. Background Art

[0002] Photovoltaic light-chasing swing arm is a photovoltaic tracking system that acts on photovoltaic panels. It swings to keep the photovoltaic components at the best solar radiation angle to maximize the solar energy absorption efficiency. Photovoltaic light-chasing swing arms on the market generally include a swing arm disc and a swing arm main rod. The swing arm disc is provided with a disc positioning boss, and the disc positioning boss is provided with a positioning column. They are basically all made of one-piece injection molding. Due to factors such as frequent swinging of the swing arm and long-term exposure of plastic, the swing arm main rod and the positioning column are easily worn, which reduces the accuracy of the swing arm and requires replacement of the entire swing arm. In addition, the existing swing arm cannot be adapted to a variety of different models of swing arms due to the fixed position of the disc positioning boss, and has low adaptability and poor flexibility. In view of this, the existing photovoltaic light-chasing swing arm is improved and optimized. Utility Model Content
