Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic brackets, and in particular to a dynamic load self-adaptive photovoltaic bracket. Background Art

[0002] To facilitate the installation of photovoltaic modules, they are typically mounted on brackets. Traditional photovoltaic brackets are typically fixed at a fixed angle or rely on motors or hydraulic systems to adjust their angle to adapt to environmental changes. However, these designs present several challenges: The use of motors or hydraulic systems requires continuous power, making them prone to failure in remote areas or inclement weather, and resulting in high maintenance costs. In strong winds, the photovoltaic panels face a large area of ​​windward contact, and the brackets lack a buffer structure, making them susceptible to wind pressure shock, leading to structural deformation or overturning. When snow covers the photovoltaic panels, manual cleaning or single electric heating snow removal is required, which is inefficient and energy-intensive. Some adjustable brackets fail to automatically reset after the wind pressure subsides, requiring manual intervention. For example, Publication No. CN119602683A discloses a high-wind protection device for photovoltaic tracking brackets. This device deploys protective panels to reduce wind resistance, but requires complex mechanical linkage and cannot accommodate snow accumulation. Publication No. CN220830426U discloses a self-adjusting photovoltaic bracket that relies on electric actuators to adjust the bracket height, resulting in high energy consumption and inability to adapt to environmental changes. Therefore, there is an urgent need for a photovoltaic bracket that does not require continuous power supply and can adapt to wind pressure and snow accumulation. Summary of the Invention
