Technical Field

[0001] The present invention relates to the technical field of solar power generation, and in particular to a fixed solar power generation array bracket. Background Art

[0002] With the development of science and technology and the enhancement of environmental awareness, the application field of solar photovoltaic power generation as a new energy source is expanding. Solar panels are the core part of the solar power generation system. Their function is to convert the sun's radiation energy into electrical energy, or send it to batteries for storage, or drive loads. Therefore, solar panels need to be installed outdoors, such as on roofs and other places that are fully exposed to sunlight.

[0003] Solar panels are generally mounted on solar supports and placed in the sun to absorb light energy. Common solar supports include fixed supports and tracking supports. Fixed supports are widely used due to their simple structure, low cost, and maintenance-free characteristics.

[0004] In the existing technology, solar photovoltaic panels are installed at an angle to more fully absorb solar energy and convert it into electrical energy. However, in extreme weather with strong winds, the large area of ​​the solar photovoltaic panels creates greater resistance to airflow. Strong airflow can easily damage the solar photovoltaic panels, shortening their service life. Summary of the Invention

[0009] By adopting the above technical solution, the problem of airflow damaging the solar photovoltaic panel in windy weather is solved. In windy weather, the driving shaft drives the mounting shaft to rotate, thereby driving the third shaft seat to flip, and then driving the mounting plate to flip, so that the mounting plate is converted from an inclined state to a horizontal state, reducing the impact of strong winds on the mounting plate.

[0023] By adopting the above technical solution, one end of the connecting plate is moved out from the inside of the mounting plate and moved into the reserved groove at the end of an adjacent set of solar array brackets. When the second drive shaft stops rotating, multiple sets of springs drive the connecting plate to reset.

[0029] 1. The present invention solves the problem of airflow damaging the solar photovoltaic panel in windy weather by providing a mounting plate, a third axle seat and a support plate. In windy weather, the driving shaft drives the mounting shaft to rotate, thereby driving the third axle seat to flip, and then driving the mounting plate to flip, so that the mounting plate is converted from an inclined state to a horizontal state, reducing the impact of strong winds on the mounting plate. At the same time, the two ends of the support plate are displaced, and the support plate provides auxiliary support for the mounting plate in the horizontal state, further improving the stability of the mounting plate. After the mounting plate is in a horizontal state, the airflow cannot directly impact the solar photovoltaic panel, thereby protecting the solar photovoltaic panel and improving the service life of the solar photovoltaic panel.

[0030] 2. The present invention is provided with a wind wheel, a connecting plate and a reserved groove. When the mounting plate is in a horizontal state, the strong wind drives the wind wheel to rotate, thereby driving a group of second drive shafts to rotate, and then driving a group of drive gears to rotate. A group of second drive shafts drives the transmission gears to rotate, thereby driving another group of second drive shafts, and then driving another group of drive gears to rotate, and the two groups of drive gears rotate in opposite directions. The two groups of drive gears are respectively engaged with the two groups of tooth plates.

When the wind wheel rotates, a set of second drive shafts are driven to rotate, thereby driving the linkage shaft to rotate, and further driving a set of movable shafts to rotate. The two sets of movable shafts are connected by a synchronous belt, so the two sets of movable shafts rotate synchronously. Since the inner walls at both ends of the scraper are respectively threadedly connected to the outer walls of the two sets of movable shafts, the scraper is displaced and cleans the surface of the solar photovoltaic panel to prevent dust in the strong wind from falling onto the smooth surface of the solar photovoltaic panel and being adsorbed and accumulated, affecting the subsequent use effect of the solar photovoltaic panel.
