Description

Positive pressure fixed support system for solar photovoltaic panels

Technical Field

The utility model mainly relates to solar photovoltaic power generation technology, in particular to a positive pressure type fixed support system for solar photovoltaic panels.

Background technique

Solar energy is the energy generated by the continuous nuclear fusion reaction process of sunspots inside or on the surface of the sun. Solar energy has the advantages of abundant resources, longevity, wide distribution, safety, cleanliness and reliable technology. Since solar energy can be converted into many other forms of energy, its application range is very wide. To obtain electricity from solar energy, it needs to be achieved through photoelectric conversion of solar cells.

When installing existing solar photovoltaic panels, most of them are first installed in an aluminum frame, and then the aluminum frame is connected to the base by bolts. The molding cost of the aluminum frame is extremely high, and the aluminum frame is easy to deform. The weight of the photovoltaic panel is large. After long-term use, the photovoltaic panel will fall off under the action of wind and rain.

In order to solve the stability problem of the aluminum frame, the prior art also proposes to replace the aluminum frame with a steel frame. When the steel frame is connected to the base, in order to ensure the convenience of installation, a connecting edge extending outside the outline of the steel frame will be formed on the steel frame so that the bolts can be installed without being interfered by the steel frame itself. However, the connecting edge extending outside the outline of the steel frame does not play any role in the overall strength of the steel frame. It only plays a connecting role. This steel frame and the base are divided into two independent parts. In order to ensure the load-bearing capacity and structural strength of the frame itself, the wall thickness of the frame is often made thicker, and the frame profile material consumption is large and the cost is high. In addition, in order to adapt to this connecting edge structure extending outside the outline of the steel frame, the overall size of the steel frame becomes larger, which further increases the material cost of the steel frame. In addition, this bolt penetration installation structure is extremely inconvenient during on-site installation, which affects the installation efficiency.
