DETAILED DESCRIPTION

[0023] The technical solution of the present invention is further elaborated in detail below in conjunction with specific embodiments. The parts that are not described and disclosed in detail in the following embodiments of the present invention should be understood as the existing technologies known or should be known to those skilled in the art, such as the model of the main support plate 1, the model of the first support rod 2, the model of the second support rod 3, and the connection method between the main support plate 1 and the support leg 102.

[0024] Example 1

[0025] A frame structure of a spliced ​​photovoltaic bracket, such as Figure 1 and Figure 5 As shown, the frame structure is formed by splicing four main support plates 1 to form a rectangular space for accommodating photovoltaic modules 4. The longitudinal section of each main support plate 1 is an arc convex upward, and a cavity 101 with an opening facing downward is formed inside. A number of horizontal first support rods 2 and vertical second support rods 3 are penetrated along the length direction of the main support plate 1, wherein the first support rod 2 passes through the bottom opening of the cavity 101, and both ends are fixedly connected to the side wall of the main support plate 1. The cavity 101 can also be used as a wiring space, so that the wiring of the photovoltaic module 4 is more neat and orderly. The bottom end of the second support rod 3 passes through the main support plate 1 and the first support rod 2 downward in sequence and is fixed to form a multi-point fixed connection between the main support plate 1 and the first support rod 2. The second support rod 3 forms a fixed point at the intersection with the main support plate 1, the second support rod 3 forms a fixed point at the intersection with the first support rod 2, and the first support rod 2 forms a fixed point at the intersection with the main support plate 1. The multiple fixed points make the coordination effect between the main support plate 1, the first support rod 2 and the second support rod 3 better, and make the support strength higher. The top end of the second support rod 3 protrudes from the top of the main support plate 1, and the photovoltaic component 4 is placed on the main support plate 1, and the edge of the photovoltaic component 4 abuts against the end of the second support rod 3 higher than the main support plate 1, and the lower surface of the photovoltaic component 4 contacts the top of the main support plate 1. The contact area between the edge of the photovoltaic component 4 and the second support rod 3 is reduced, and the heat dissipation effect is better. At the same time, it also ensures the supporting effect of the frame structure on the photovoltaic component 4.

[0026] The four main support plates 1 are connected by connectors 5 to form a rectangular space for accommodating the photovoltaic module 4. To facilitate connection, the connector 5 is a metal connector, and the cross section of the metal connector is fan-shaped. The side of the metal connector is fixedly connected to the ends of the adjacent main support plates 1, and can be specifically arranged to be welded, so that the connection is tighter and more stable. In order to ensure a better support effect of the frame structure, support legs 102 are arranged at both ends of the main support plate 1.

A clamping platform 302 is formed between the side wall of the second support rod 3 and the upper surface of the bearing platform 301. The edge of the photovoltaic module 4 abuts against the clamping platform 302, which is conducive to the dissipation of waste heat generated by the edge of the photovoltaic module 4 and ensures the support strength of the frame structure.
