Description

Technical Field

[0001] The utility model relates to the technical field of wind prevention for photovoltaic tracking brackets, and particularly relates to a wind prevention assembly for a photovoltaic tracking bracket provided with a wind guiding member. Background Technique

[0002] In the construction and operation of photovoltaic power stations, as a key device for supporting and adjusting solar photovoltaic panels, the stability and safety of photovoltaic tracking brackets are directly related to the overall performance and economic benefits of the power station. With the continuous progress of photovoltaic technology and the continuous growth of the global demand for renewable energy, the application of photovoltaic tracking brackets is becoming increasingly widespread. However, in the actual operation process, especially in areas with strong winds, photovoltaic tracking brackets are easily affected by wind-induced resonance, resulting in damage or even failure, seriously affecting the stable operation and power generation efficiency of the power station.

[0003] In a photovoltaic tracking bracket with a wind prevention mechanism disclosed in the patent No. CN218734074U, it includes a photovoltaic support plate and a solar panel installed inside the photovoltaic support plate. One side of one end of the photovoltaic support plate is screwed with an anemometer electrically connected to an external power supply through a mounting seat. Four corners of the bottom end of the photovoltaic support plate are symmetrically distributed with a support mechanism. The support mechanism includes a support, a ball head hinge shaft and a lifting frame. The support and the lifting frame, as well as the lifting frame and the photovoltaic support plate, are all hinged through the ball head hinge shaft. The utility model provides a photovoltaic bracket that can be folded and stored in bad weather or strong winds to reduce the windward area. In strong wind weather, the lifting frame can be folded to make the photovoltaic support plate carry the solar panel and fold with the support, which is equivalent to lying flat on the ground or a building to reduce the windward area of the photovoltaic support plate and avoid being blown down and damaged.

[0004] In the above-mentioned prior art, the photovoltaic panel realizes the folding of the lifting frame through the cooperation of the support mechanism and the lifting frame, keeps the photovoltaic panel in a horizontal state to realize wind resistance, but the photovoltaic bracket still presents a bare state and lacks corresponding external wind resistance protection. In the case of strong winds, the wind acting on the photovoltaic tracking bracket will still cause damage to the photovoltaic bracket, resulting in possible displacement, inclination or even collapse of the photovoltaic tracking bracket. Therefore, corresponding improvements are needed. Content of the Utility Model
