[0044] In order to cooperate with the insertion of the insertion rod 17 into the slot 19, the fixing frame 18 is also equipped with an elastic member, which is a spring 20. The spring 20 is installed in the fixing frame 18 and sleeved on the insertion rod 17. The side wall fixing ring of the insertion rod 17 is provided with a stopper 21, one end of the spring 20 is fixedly connected to the stopper 21, and the other end of the spring 20 is fixedly connected to the inner wall of the fixing frame 18.

[0045] In practice, the distance between the transverse frame 3 of each photovoltaic module 37 and the edge of the photovoltaic module 37 is different. In order to facilitate the edge wrapping piece 12 to be suitable for different photovoltaic modules 37, the lower stopper 15 is first driven to slide in the slide groove 16, and when the edge of the photovoltaic module 37 is aligned with the edge wrapping space, the edge wrapping piece 12 is then driven to move toward the photovoltaic module 37, and the photovoltaic module 37 is inserted into the edge wrapping space. Then, the bolts 9 and nuts 10 are tightened in sequence, and the lower stopper 15 is fixed in the slide groove 16, and the edge wrapping piece 12 is wrapped around the edge of the photovoltaic module 37.

[0046] See also Figure 5 In order to facilitate the adjustment of the installation angle of the photovoltaic module 37, a rotating seat 22 is fixedly installed in the stand 1. A rotating rod 23 is rotatably installed in the rotating seat 22, and an adjustment groove 24 is opened on the outer wall of the rotating seat 22, and the adjustment groove 24 is opened along the arc length direction of the rotating seat 22. A connecting block 25 is fixedly connected to the side wall of the rotating rod 23, and one end of the connecting block 25 extends outside the adjustment groove 24, and the arc length of the adjustment groove 24 is the swing path of the connecting block 25. One end of the connecting block 25 is welded to the bottom surface of the middle cross frame 3.

[0047] In order to facilitate the rotation of the rotating rod 23 in the rotating seat 22, the stand 1 is equipped with a swing mechanism, which includes a disc 26 and a swing rod 27. One end of the rotating rod 23 passes through the rotating seat 22 and the stand 1 in sequence, and extends outside the stand 1. The disc 26 is coaxially fixed to one end of the rotating rod 23.

One end of the swing rod 27 is hinged to the top surface of the slider 28, and the other end of the swing rod 27 is eccentrically hinged to the bottom surface of the disc 26.

[0048] In order to facilitate the movement of the slider 28, the stand 1 is equipped with a driving assembly, which includes a screw 29. An adjustment seat 30 is fixedly installed on the outer wall of the stand 1, and the screw 29 is rotatably installed in the adjustment seat 30. A transmission block 31 is slidably installed on the outer wall of the stand 1, and the transmission block 31 is slidably installed along the vertical direction of the stand 1 through a dovetail block. The screw 29 thread penetrates the transmission block 31, and a transmission rod 32 is fixedly connected to the side of the transmission block 31 facing the slider 28, and the transmission rod 32 is fixedly connected to the slider 28.

[0049] When the screw 29 is rotated, the screw 29 drives the transmission block 31 to move in the vertical direction, and the transmission block 31 then drives the slider 28 to move in the vertical direction through the transmission rod 32. The slider 28 then drives the disk 26 to rotate through the swing rod 27, and the disk 26 drives the rotating rod 23 to rotate, and the rotating rod 23 then drives the photovoltaic assembly 37 to swing through the connecting block 25. In addition, since the screw 29 has a self-locking function, when the screw 29 is loosened, the photovoltaic assembly 37 is fixed at the current tilt angle.

[0050] It is worth mentioning that in this embodiment, the screw 29 has two sections of threads with opposite thread directions, and the transmission block 31, the transmission rod 32, the slider 28 and the rocker 27 are each provided in two groups. The two groups of rocker 27 make the rotation of the disc 26 more stable.

[0051] See also Figure 3 In order to facilitate clamping the edge of the photovoltaic module 37 in the edge wrapping space, a press seat 33 is installed on the inner side of the upper stopper 13. A rotating member 38 is threadedly connected to the top surface of the upper stopper 13, and one end of the rotating member 38 is rotatably connected to the top surface of the press seat 33. In this embodiment, the rotating member 38 is a bolt, and the material of the press seat 33 is rubber.

[0052] When the edge of the photovoltaic module 37 is inserted into the edge wrapping space, the rotating member 38 is tightened, and the rotating member 38 drives the pressing seat 33 to press against the surface of the photovoltaic module 37. Under the action of the rotating member 38, it is conducive to adapting to photovoltaic modules 37 of different thicknesses and improving the stability of the edge wrapping of the photovoltaic module 37 by the edge wrapping member 12.

The side wall of the press seat 33 is also fixedly connected with a water receiving pipe 35, which is respectively connected to the multiple water holes 34, and the end of the water receiving pipe 35 away from the press seat 33 is connected to a water source.

[0054] When the surface of the photovoltaic module 37 needs to be cleaned, the water source is turned on, and the water flows into the pressure seat 33 through the water receiving pipe 35, and then the water is sprayed out from the multiple water holes 34 respectively, thereby cleaning the surface of the photovoltaic module 37.

[0055] It should be noted that see Figure 1 The side wall of the stand 1 is fixedly connected with a reinforcing rib 36, and one end of the reinforcing rib 36 away from the stand 1 is fixedly connected to the ground. Under the action of the reinforcing rib 36, the strength of the stand 1 is increased, and the stability of the stand 1 supporting the photovoltaic module 37 is improved.

[0056] Working principle of a photovoltaic module fixing device:

[0057] When the photovoltaic module 37 needs to be installed on the roof, the photovoltaic module 37 is first connected and fixed through the horizontal frame 3 and the vertical frame. Then the photovoltaic module 37 is pre-placed flat on the vertical frame 1, and the connecting block 25 is welded to the horizontal frame 3 in the middle of the bottom surface of the photovoltaic module 37, and the first support plate 4 is fixedly connected to the horizontal frame 3 at both ends of the bottom surface of the photovoltaic module 37. Under the fixed support of the support rod 6 and the connecting block 25, the photovoltaic module 37 is horizontally fixed on the vertical frame 1.

[0058] When the inclination angle of the photovoltaic assembly 37 needs to be adjusted, the bolt 9 and the nut 10 on the sub-pole frame 7 are first loosened, and then the screw rod 29 is rotated, the screw rod 29 drives the transmission block 31 to move in the vertical direction, and the transmission block 31 then drives the slider 28 to move in the vertical direction through the transmission rod 32. The slider 28 then drives the disk 26 to rotate through the swing rod 27, and the disk 26 drives the rotating rod 23 to rotate, and the rotating rod 23 then drives the photovoltaic assembly 37 to swing through the connecting block 25. When the photovoltaic assembly 37 rotates to the desired inclination, the screw rod 29 is loosened. Since the screw rod 29 has a self-locking function, when the screw rod 29 is loosened, the photovoltaic assembly 37 is fixed at the current inclination angle. Finally, in order to prevent the screw rod 29 from rotating and causing the photovoltaic assembly 37 to swing, the bolts 9 and the nuts 10 are tightened respectively, so that the photovoltaic assembly 37 is stably fixed at the current swinging angle.

[0059] In summary, the photovoltaic assembly 37 is supported and fixed by the stand 1 composed of three columns, which not only reduces the floor space occupied by the photovoltaic assembly 37 but also improves the utilization rate of the rooftop space.

[0060] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
