Description

Technical Field

[0001] The utility model belongs to the technical field of photovoltaic brackets, and particularly relates to a photovoltaic bracket. Background Art

[0002] Photovoltaic power generation utilizes solar energy, a renewable energy source. Unlike non-renewable energy sources such as fossil fuels, solar energy is ubiquitous and has huge energy, which can meet human needs for energy. Photovoltaic power generation systems can be divided into two types: centralized photovoltaic and distributed photovoltaic, depending on their scale and operation mode. Centralized photovoltaics are generally large in scale and are mainly installed in relatively wide areas such as mountains, water surfaces, and deserts. They collect solar energy through a large number of photovoltaic panels or solar tracking systems, and convert it into electrical energy and transmit it to users far away from the power generation site; while distributed photovoltaic power stations are generally small in scale, but the installation location is more flexible and can make full use of space resources, such as curtain walls, roofs, highway slopes, etc.

[0003] Frame beam is a common slope support structure. This type of beam is usually exposed on the slope surface and distributed in a grid pattern. It is used to reinforce and stabilize the slope to prevent slope landslide and instability. The frame beam slope occupies a large area. For distributed photovoltaics, this part of the space is worth using. The slope photovoltaic brackets on the market are generally fixed by piling. Obviously, this is not suitable for slope structures with frame beams.

[0004] In view of the above situation, it is necessary to provide a photovoltaic support structure that is easy to construct and has a stable structure to solve the above technical problems. Utility Model Content
