Description

Technical Field

[0001] The utility model relates to the field of photovoltaic brackets, in particular to a photovoltaic bracket capable of 360-degree movable rotation. Background Art

[0002] With the country's vigorous advocacy of photovoltaic power generation, a new energy source with energy-saving and environmental protection significance, the construction of photovoltaic power station projects has been carried out in various places. The main income of photovoltaic power stations is the income from power generation. Therefore, increasing the power generation is also an important way to solve the problem of long investment recovery period of power stations. The power generation of photovoltaic power stations is affected by the geographical location of the photovoltaic power station, the time and position of the sun in the year, and the installation inclination of solar photovoltaic modules.

[0003] Since there are many barren mountains in the eastern part of my country, most of them belong to hilly areas, and the mountains are changeable and the landforms are complex, in order to obtain the best power generation efficiency of solar photovoltaic modules, it is necessary to adjust the installation angle of solar photovoltaic modules according to the topography of the power station. The existing fixed photovoltaic brackets have a fixed installation angle of photovoltaic modules, and the inclination cannot be adjusted at any time according to the geographical location of the project. The factors of the changing position of the sun in different seasons and times are not taken into account. Therefore, the power generation efficiency of the photovoltaic power station cannot be optimized.

[0004] In addition, the existing patent No. 2015206453753 discloses a 360° rotating and tilt-adjustable photovoltaic bracket, which specifically includes a base with a horizontal upper surface, a column fixed at one end to the base, a bracket connected to the end of the column not connected to the base, and a diagonal brace, one end of which is connected to the column, and the other end of which is connected to one end of the bracket through an angle connector, and the bracket is connected to the column through an adapter. All the weight of the photovoltaic panel is supported and connected by a single column. In the case of a large number of photovoltaic modules, the supporting capacity of the column will be strictly tested. If multiple support columns are set for support, the rotation of the photovoltaic panel cannot be achieved in the prior art. Utility Model Content
