One of the most important requirements for any type of photovoltaic support is that the structure must be firm and reliable, capable of bearing wind load and other external effects. At the same time, after installation, it must be safe and reliable to achieve the maximum use effect with the minimum installation cost, and to minimize the number of maintenance and maintenance costs.

[0003] The main structure of the photovoltaic support currently in wide use is an installation rail, and installation grooves are provided on the upper and lower installation surfaces of the rail, or installation grooves are provided on one surface and long circular holes are provided continuously and at intervals on the other surface, such as C-shaped steel. The installation grooves or long circular holes in the lower part of the rail are used to connect the bottom fixing member to fix the rail on a building or the ground, and the installation grooves in the upper part of the rail are used to bolt the pressing block to press and fix the solar component on the rail. This type of photovoltaic support has simple structure, low cost and relatively simple operation, and has been widely used. However, since a plurality of installation grooves or long circular holes are provided continuously on the rail, the processing steps of the rail are more, the processing cost is increased, and the structural continuity of the material is damaged, thereby reducing the structural strength of the rail.

[0004] Therefore, there is an urgent need for a photovoltaic support with simple structure, convenient installation, low cost and high strength. SUMMARY

[0025] Referring to Figs. 1-4The utility model relates to a kind of clamping type photovoltaic support, including guide rail 1 and buckle 2;

[0026] The cross section of the guide rail 1 is a rectangular frame 11, and the clamping portions 12 are arranged on both sides of the top surface of the rectangular frame 11. The C-shaped mounting groove 13 is arranged at the bottom of the rectangular frame 11. The clamping portion 12 is a protruding rectangular frame 11 with a barb structure. The C-shaped mounting groove 13 is connected with the fixing member 4 fixed on the roof or ground through the T-shaped bolt 3.

[0027] The buckle 2 is a C-shaped structure. The connecting grooves 21 for clamping with the clamping portions 12 are arranged at the two open ends of the C-shaped structure of the buckle 2. The connecting portions 22 for connecting the mounting bolts 5 are arranged in the middle of the C-shaped structure of the buckle 2. The ends of the connecting grooves 21 are provided with hooks that are clamped in the barb of the protruding edge. The clamping of the connecting grooves 21 and the clamping portions 12 is achieved. The connecting portions 22 include two L-shaped legs 23 symmetrically arranged on the inner side of the middle of the C-shaped structure of the buckle 2. The mounting nuts 8 are placed in the connecting portions 22. The mounting bolts 5 are connected with the mounting nuts 8 in sequence through the pressing blocks 7 and the buckle 2.

[0028] Since the buckle 2 is a C-shaped structure, it has a certain opening deformation ability when subjected to an opening tension. Therefore, when the connecting grooves 21 of the buckle 2 are tightly pressed on the top surface of the guide rail 1, the hooks of the buckle 2 are subjected to the outward expansion force of the protruding edge of the guide rail 1. The hooks of the connecting grooves 21 can easily slide into the barb of the protruding edge of the guide rail 1. The buckle 2 is clamped with the clamping portions 12 through the hooks of the connecting grooves 21.

[0029] The photovoltaic modules 6 are laid on the top surface of the guide rail 1. The pressing blocks 7 are connected with the buckle 2 through the mounting bolts 5. The pressing blocks 7 tightly fix the photovoltaic modules 6 on the guide rail 1, and the installation and fixation of the modules are completed.

[0030] The photovoltaic support of the utility model adopts the clamping mode of the guide rail 1 and the buckle 2. The guide rail 1 adopts a complete rectangular cross-sectional structure, which is simple in structure and does not need to open multiple installation grooves or long waist holes. It has higher structural strength. For the guide rail made of aluminum alloy, it can be extruded in one step, which is simpler to process and manufacture and has lower cost. The guide rail 1 and the buckle 2 are clamped, which is simple and convenient to operate and has high installation efficiency.

[0031] In addition: It should be noted that the above specific embodiments are only one optimization scheme of the patent. Any changes or improvements made by the person skilled in the art based on the above concept are within the protection scope of the patent.
