[0023] The connecting mechanism includes a connecting block 3 fixedly connected to the lower end surface of the outer frame 1. A sliding groove is opened on one side of the connecting block 3 close to the photovoltaic panel 2. A sliding block 4 is slidably connected to the inner wall of the sliding groove. A limiting plate 13 is fixedly connected to one end of the connecting block 3. The limiting plate 13 closes one end of the sliding groove, so that the sliding block 4 is positioned after sliding in the sliding groove, avoiding slipping over and resulting in loose clamping between the sliding block 4 and the sliding groove. Connecting blocks 3 are fixedly connected to the lower end surfaces of two adjacent outer frames 1. A sliding groove is opened on one side of the connecting block 3 close to the photovoltaic panel 2. A sliding block 4 matching the sliding grooves on two adjacent connecting blocks 3 is slidably clamped in the sliding groove, so that two adjacent outer frames 1 are connected together. This connecting mechanism has a simple structure, and this sliding connection and clamping method between the sliding block 4 and the sliding groove makes the installation simple, realizes rapid installation, and improves the installation efficiency;

[0024] The grounding mechanism includes a connecting column 5, an upper connecting screw 6 and a lower connecting screw 11 fixedly connected to the center of the bottom surface of the sliding block 4. A threaded hole is opened on the bottom surface of the connecting column 5, and the upper connecting screw 6 is threadedly connected to the threaded hole in the connecting column 5. Fixing rings 7 are fixedly connected to the middle parts of the upper connecting screw 6 and the lower connecting screw 11. The upper part of the upper connecting screw 6 above the fixing ring 7 is provided with threads matching the threaded hole in the connecting column 5 and the lower part has no threads. The lower part of the lower connecting screw 11 below the fixing ring 7 is provided with threads and the upper part has no threads. An upper joint 8 is movably connected to the outer surface of the upper connecting screw 6 above the fixing ring 7, and a grounding wire 9 is fixedly connected to one end of the upper joint 8;

[0025] The bottom end of the ground wire 9 is fixedly connected with a lower joint 10. The lower joint 10 is movably connected to the outer surface of the lower connecting screw 11 below the fixing ring 7. The ends of the upper joint 8 and the lower joint 10 away from the ground wire 9 are both arc-shaped ends with round holes. The upper joint 8 and the lower joint 10 are respectively movably sleeved on the threaded ends of the upper connecting screw 6 and the lower connecting screw 11 through the round holes. The bottom end of the lower connecting screw 11 is threadedly connected with a ground stake 12. The top of the ground stake 12 is provided with a threaded hole matching the lower connecting screw 11.

[0026] The grounding mechanism is quickly installed by sleeving the upper joint 8 and the lower joint 10 on the threaded ends of the upper connecting screw 6 and the lower connecting screw 11 respectively, and then threadedly connecting the threaded ends with the threaded holes in the connecting column 5 and the ground stake 12 respectively. Cross bars 14 are fixedly connected to the non-threaded ends of the upper connecting screw 6 and the lower connecting screw 11. The upper connecting screw 6 and the lower connecting screw 11 can be tightened more conveniently through the cross bars 14, further improving the installation efficiency.

[0027] The functional principle of the present utility model can be described through the following operation methods:

[0028] During use, connecting blocks 3 are fixedly connected to the lower end faces of two adjacent outer frames 1. A sliding groove is provided on one side of the connecting block 3 close to the photovoltaic panel 2. A sliding block 4 matching the sliding grooves on two adjacent connecting blocks 3 is slidably clamped in the sliding grooves, so that two adjacent outer frames 1 are connected together. When multiple outer frames 1 need to be connected, only by sliding and clamping the sliding block 4 in the sliding grooves on two adjacent connecting blocks 3 between every two outer frames 1, the connection of multiple consecutive outer frames 1 can be realized. This connection mechanism has a simple structure, and this connection method of sliding and clamping the sliding block 4 and the sliding groove makes the installation simple, realizes quick installation, and improves the installation efficiency.

[0029] The connection of the grounding mechanism is to first sleeve the upper joint 8 and the lower joint 10 on the threaded ends of the upper connecting screw 6 and the lower connecting screw 11 respectively, and then screw the upper connecting screw 6 and the lower connecting screw 11 into the threaded holes in the connecting column 5 and the ground stake 12 respectively and tighten them through the cross bars 14. Due to the simple structure of the grounding mechanism and the setting of the cross bars 14, the grounding mechanism is quickly installed, improving the installation efficiency.
