Biaxial flexible photovoltaic tracking bracket

Abstract

The invention discloses a biaxial flexible photovoltaic tracking bracket. The biaxial flexible photovoltaic tracking bracket comprises a bracket body; the bracket is used for installing and fixing solar cell panels; the bracket is horizontally provided with multiple solar cell panel sets; the solar cell panel sets are arranged on at least two steel wire ropes; brace rods are arranged at two ends of the steel wire ropes; the brace rods can turn over along the axis of the solar cell panel sets corresponding to the bracket; an overturning mechanism for driving the brace rods to rotate is arranged on the bracket; the solar cell panel sets are composed of multiple solar cell panels; one ends of the solar cell panels are hinged corresponding to the steel wire ropes; and north and south angle adjusting mechanisms for driving the solar cell panels to rotate are arranged at the other ends of the solar cell panels. The flexible steel wire ropes are used as cell panel support beams; structural installation cannot be influenced by the position and the height; a foundation height levelling upright post does not need to be adjusted; the biaxial flexible photovoltaic tracking bracket can be used in any terrain; furthermore, the span can be increased by above 10 m; and thus, installation and use requirements of multiple scenes can be satisfied.

Description

technical field [0001] The invention relates to the field of photovoltaic power generation, in particular to a biaxial flexible photovoltaic tracking bracket. Background technique [0002] In a solar photovoltaic power generation system, the maximum power generation effect can be achieved if the incident angle of sunlight is perpendicular to the panel surface, but the general power station uses the annual average best fixed inclination to install the panels, which cannot achieve the ideal power generation effect. In general photovoltaic power plants, the structure supporting the battery panels is rigid, which requires high land flatness and installation accuracy, and the cost is high. In particular, my country's photovoltaic installations are gradually moving eastward. Due to the poor power consumption capacity in the west, excess power has limited power generation. There are many mountainous areas in the central and eastern regions of my country, fish ponds, agricultural f...

Problems solved by technology

[0002] In the solar photovoltaic power generation system, the incident angle of sunlight is perpendicular to the surface of the battery panel to achieve the maximum power generation effect, but the general power station uses the annual average best fixed inclination to install the battery panel, which cannot achieve the ideal power generation effect

In ordinary photovoltaic power stations, the structure supporting the battery panels is rigid, which requires high land flatness and installation accuracy, and the cost is high

Especially at present, my country's photovoltaic installations are gradually moving eastward. Due to the poor power consumption capacity in the west, excess power has limited power generation.

There are many mountainous areas in the central and eastern regions of my country, fish ponds, agricultural facilities, and industrial and commercial roofs. In these photovoltaic installation scenarios, ordinary rigid beam supports need to adapt to complex environments, which are expensive and difficult to construct.

[0003] In the existing technology, the beams used to support the battery panels on the fixed brackets are rigid components. If the terrain is undulating, crossing waters, and large-span structures, it cannot meet the use and design requirements, or the cost is very high.

[0004] In the traditional uniaxial tracking, the main girder is a rigid profile. Due to the deformation of the main girder due to factors such as foundation settlement, installation, and terrain, it will be stuck due to deformation and cannot rotate. Moreover, the moment of the inclined uniaxial is unbalanced, and the lower end bearing is easy to Damaged, the bearing still needs to be maintained, and the cost is high
