Description

Technical Field

[0001] The utility model specifically relates to the technical field of photovoltaic brackets, in particular to a lightweight photovoltaic bracket and a photovoltaic power station. Background Art

[0002] Photovoltaic power station refers to a photovoltaic power generation system that is connected to the power grid and transmits electricity to the power grid. It is a green energy project encouraged by the state. It can be divided into grid-connected power generation systems with batteries and without batteries. Solar power generation is divided into solar thermal power generation and photovoltaic power generation. Solar power generation usually refers to solar photovoltaic power generation.

[0003] Chinese patent announcement number CN 206259888 U discloses a photovoltaic bracket and a photovoltaic bracket group, which relate to the field of solar photovoltaic power generation. The photovoltaic bracket includes a bracket column, an angle adjustment strut, a bracket diagonal beam, a first transmission rod and a fixing. One end of the bracket column is hinged to the bracket diagonal beam. One end of the bracket diagonal beam is hinged to one end of the angle adjustment strut. A serration groove is provided on the angle adjustment strut, and a first gear is provided on the first transmission rod, and the first gear cooperates with the serration groove. The first transmission rod is rotatably connected to the bracket column to adjust the distance from the first gear to the connecting part. The angle adjustment strut can be connected to the bracket column through a fixing;

[0004] The above-mentioned photovoltaic bracket can be rotated slightly to change the inclination angle of the photovoltaic panel; however, the rotation of the above-mentioned photovoltaic bracket is achieved through the meshing of two gears, and the bracket is rotated by controlling the rotation of the gears. At the same time, the gears are also subject to the reaction force generated by the bracket due to gravity. The photovoltaic bracket is placed in open spaces or roofs and other places, which are exposed to wind and sun all year round. The gears are prone to rust and the like under the influence of the external environment, and the two gears are known to be in a state of forced meshing, which will cause increased wear. After long-term use, the gears will be damaged, which may cause the two gears to fail to rotate normally, and may also cause the two gears to idle, resulting in the gears being unable to support the bracket normally.

[0032] By adopting the above technical solution, when in use, multiple brackets 1 are evenly placed in a straight line on the roof or the ground, and multiple fixing seats 4 are fixedly connected to the ground or the roof by bolts.
