[0027] The technical scheme in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model and not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.

[0028] The core of the utility model is to provide a top bracing device for photovoltaic module installation, which can more conveniently fix photovoltaic module.

[0029] The utility model provides a top bracing device for photovoltaic module installation specific embodiment one, please refer to Figures 1 to 3 , including chassis 2 and the top bracing part 1 connected in the top end of chassis 2. Top bracing part 1 includes a plurality of circumferentially spaced top bracing rod 11, here circumferential refers to with chassis 2 as the axle, the direction around the axle, thereby each top bracing rod 11 is arranged radially around the top end of chassis 2. Top bracing rod 11 is telescopic rod, thereby through the telescopic of top bracing rod 11, changes the interval between the both ends of top bracing rod 11.

[0030] In the process of fixing the photovoltaic module 4, the top support rod 11 can be retracted first to leave space below the frame 41 of the photovoltaic module 4, and then the photovoltaic module 4 is placed above the top support part 1 and supported by the top support part 1. At this time, since the top support rod 11 avoids the frame of the photovoltaic module 4, the frame 41 of the photovoltaic module 4 will not collide with the top support rod 11. Then the top support rod 11 is controlled to extend to laterally abut against the frame 41 of the photovoltaic module 4 to fix the photovoltaic module 4. The fixing is firm, the lifting action during the fixing of the photovoltaic module 4 can be reduced, the photovoltaic module 4 is more conveniently fixed, and the possibility of injuring the worker is reduced. At the same time, since the top support rod 11 is telescopic, it can cope with photovoltaic modules 4 of different sizes, and ensure that the top support rod 11 can adaptably extend into the frame 41 of photovoltaic modules 4 of different models.

[0031] Further, the top support part 1 is rotatably connected to the top end of the base frame 2. As shown in Figure 2 and Figure 3 When the support force of the top support rod 11 and the frame 41 of the photovoltaic module 4 form an included angle to form a torsional force, the photovoltaic module 4 can be held or the gravity of the photovoltaic module 4 is used to make the top support rod 11 rotate relative to the base frame 2 during the extension to abut against the frame 41 of the photovoltaic module 4. It is not necessary to manually adjust the angle of the photovoltaic module 4, which further facilitates the installation of the photovoltaic module 4, ensures the firmness of the support, effectively avoids the displacement between the photovoltaic module and the top support part 1 after the photovoltaic module is fixed, and improves the safety.

[0032] The top support part 1 can be rotatably connected to the base frame 2 through a bearing, a gear assembly, a shaft coupling or the like, or directly rotatably inserted or sleeved on the top end of the base frame 2. Of course, in other embodiments, the top support part 1 can also be fixed to the top end of the base frame 2.

[0033] During the process of placing the photovoltaic module 4 above the top support part 1, manual positioning and alignment will also be performed, so the top support part 1 only needs the base frame 2 to have a small rotatable angle and be able to be finely adjusted, for example, 5° or 10°, to further improve the convenience of assembly and avoid large rotation of the top support part 1 relative to the base frame 2.

[0034] Further, a locking structure is arranged between the base frame 2 and the top support part 1 to lock the angle between the top support part 1 and the base frame 2, so as to avoid the top support part 1 and the photovoltaic module 4 assembled thereon from shaking relative to the base frame 2. Specifically, the locking structure can include a plug rod which is inserted into the top support part 1 and the base frame 2 to achieve locking, and can also be a bolt structure.

[0035] In the top support part 1, as shown in Figure 1 and Figure 3As shown, the top support portion 1 also includes a support head 12 fixed to one end of the top support rod 11. The other end of the top support rod 11 is connected to the top of the base frame 2.

[0036] By adding the support head 12, the side of the frame 41 can be matched for support, increasing the support area, forming an effective support for the frame 41 of the photovoltaic module 4, and improving the support stability. Of course, in other embodiments, the top support rod 11 can also be directly supported at the top corner between the side faces of the frame 41, or an angled support head 12 can be added.

[0037] The support head 12 and the top support rod 11 are arranged in a T-shape as a whole. Figure 1 The support head 12 extends from two opposite sides of the top support rod 11, so that the support head 12 and the top support rod 11 form a T-shaped structure.
