Description

Distributed non-load-bearing photovoltaic support on cement roof

technical field

The utility model relates to the technical field of photovoltaic equipment, in particular to a distributed non-load photovoltaic support on a cement roof.

Background technique

With the vigorous development of the photovoltaic industry, large-scale ground power stations are increasingly restricted. Cement flat roofs account for a large proportion of distributed photovoltaic systems. However, due to the small size and complexity of cement roofs, a project consists of multiple roofs. Moreover, the irregular arrangement of the roof components results in a variety of supports, and the installation is time-consuming and labor-intensive. The existing cement roof distributed photovoltaic power station support is divided into fixed support and ballast photovoltaic support. The fixed support needs to add cement piers or cement strip bases on the original cement roof as the support foundation. Due to the heavy weight of the cement piers and cement strip bases, the constant load of the cement roof is increased, which has a great impact on the original structure, and the cement piers and cement strips Base installation is labor-intensive and time-consuming. The ballast-type photovoltaic support needs to be fixed by the bottom guide rail, and the support is fixed on the bottom guide rail with cement briquettes. However, the ballast-type photovoltaic support uses a large amount of weight blocks, and the installation costs materials and time.

Utility model content

Preferably, the bent leg is V-shaped, and a section of the bent leg near the lower end is arranged horizontally.

Preferably, the included angle of the bent legs is an obtuse angle.

Preferably, the bent leg is a one-time bent shaped part.

Preferably, the bent leg, the adapter and the pressing block are fixed through bolt connection.

Preferably, the back plate, the side plate and the bent legs are fixed through bolt connection.

The beneficial effects of the utility model:

1. The unit modular structure design is adopted, the bracket unit and the array unit can be pre-spliced in the factory, the stringing method is flexible and follow-up, saving on-site installation time, bolt connection assembly, no welding points, the installation process is simple and easy to shape, safe and reliable.

2. The entire photovoltaic support has passed the wind tunnel test. In practical applications, no load-bearing blocks are required, and the wind pressure has less influence on the support. The lightning protection system of the entire power station is undertaken by the support structure. It only needs to be connected with the support with flat iron on the outermost periphery. Form a lightning protection system.

3. The overall array photovoltaic bracket forms a whole array through the side panels and the back panel, which has the advantages of light weight, convenient installation, convenient disassembly, fewer components, less material, low cost, and no damage to the roof.
