Problems solved by technology
[0005] However, the disadvantages of the existing electric push rod and long connecting rod drive crank mechanism transmission scheme are: the connecting rod is heavy, the driving power is large, the work efficiency is low, and the installation is inconvenient
The disadvantages of the wire rope and pulley (or reel) transmission scheme are: it is greatly affected by wind resistance, and at the same time requires a large wire rope tension, which is difficult to control, resulting in an inaccurate rotation angle, which cannot make the battery panel components absorb better. Solar power, poor practicality

The invention discloses a rotating bracket for a solar battery assembly. The rotating bracket comprises a support, a winding drum, a drawing device, a supporting shaft and a bracket, wherein an axis of the winding drum is in a vertical direction and the winding drum is rotatably arranged on the support; the drawing device drives the winding drum by a steel wire rope to change horizontal movement of the drawing device to rotary movement of the winding drum; the supporting shaft extends along a vertical direction and is coaxially arranged on the winding drum; and the bracket is arranged on the supporting shaft and the solar battery assembly is arranged on the bracket. According to the rotating bracket disclosed by the embodiment of the invention, influences by wind resistance are small; and the rotating bracket has the advantages of compact and simple structure, convenience for installation and low driving energy consumption. The invention further discloses a solar battery system.
Description
technical field [0001] The invention relates to the field of solar power generation, in particular to a slewing support for a solar battery assembly and a solar battery system. Background technique [0002] Solar photovoltaic power generation system is a power generation system that converts solar radiation energy into electrical energy through solar cells. It is mainly composed of solar battery components, tracking slewing bracket for installing battery components, controller and inverter. The controller controls the tracking slewing bracket to track the position of the sun in real time, so that the solar battery is always facing the sun, thereby maximizing the utilization of solar energy and outputting more power. [0003] Traditional solar photovoltaic power generation tracking systems commonly use two driving methods to drive the slewing bracket: (1) multiple slewing brackets are driven individually; (2) multiple slewing brackets are linked. Since the linkage of multip...
