[0033] Please refer to Figures 1 to 8 As shown, this embodiment discloses a photovoltaic support, including a column 600, an inclined beam 500, a cross beam 400, purlins 200, a pressing block 300 and a reinforcement structure for the photovoltaic module. The inclined beam 500 is arranged at the top of the column 600, and a plurality of cross beams 400 are installed at the top of the inclined beam 500 at a certain interval, and the cross beam 400 is perpendicular to the inclined beam 500; a plurality of purlins 200 are arranged at intervals on the top of the cross beam 400, and the purlin 200 is perpendicular to the cross beam 400 to form a three-layer support structure for the photovoltaic module. The pressing block 300 fixes the photovoltaic module 100 on the purlin 200, and the reinforcement structure further strengthens the fixed connection between the photovoltaic module 100 and the purlin 200. The reinforcement structure of this embodiment is suitable for strengthening the fixation between the frame 101 of the photovoltaic module 100 and the purlin 200.

[0034] Please refer to Figure 3 and Figure 8 As shown, in an embodiment of the present application, the reinforcement structure includes a reinforcement member 1 and a fastener 3. The reinforcement member 1 surrounds the outer periphery of the purlin 200 and at least partially fits with the lower surface and the side surface of the purlin 200. The fastener 3 is used to penetrate the frame 101 on the lower side of the photovoltaic module 100 and the reinforcement member 1 to fasten and connect the reinforcement member 1, the frame 101 and the purlin 200.

[0035] Please refer to Figure 1 、 Figure 2 、 Figure 6 、 Figure 7As shown, in another embodiment of the present application, the reinforcement structure further includes a connecting member 2. The reinforcing member 1 surrounds the outer periphery of the purlin 200 and at least partially fits with the lower surface and the side surface of the purlin 200. The connecting member 2 is disposed above the reinforcing member 1 and at least partially located between the photovoltaic module 100 and the purlin 200. The fastener 3 tightly connects the reinforcing member 1, the connecting member 2, and the frame 101.

[0036] Please refer to Figures 1 to 3 、 Figures 6 to 8 As shown, the reinforcing member 1 is in an inverted "U" shape, including an enclosing portion 11 and a mounting portion 12. The enclosing portion 11 surrounds the outer periphery of the purlin 200 and at least partially fits with the lower surface and the side surface of the purlin 200. The mounting portion 12 is disposed on the upper side of the enclosing portion 11. The mounting portion 12 is connected to the connecting member 2 and the frame 101. The fastener 3 passes through the frame 101 on the lower side of the photovoltaic module 100, the connecting member 2, and the mounting portion 12 to tightly connect the reinforcing member 1, the connecting member 2, the frame 101, and the purlin 200; or, the mounting portion 12 is connected to the frame 101, and the fastener 3 passes through the frame 101 on the lower side of the photovoltaic module 100 and the mounting portion 12 to tightly connect the reinforcing member 1, the frame 101, and the purlin 200.

[0037] Further, the enclosing portion 11 includes a bottom plate 111 and two side plates 112 disposed at both ends of the bottom plate 111. The bottom plate 111 at least partially fits with the lower surface of the purlin 200. The two side plates 112 are perpendicular to the bottom plate 111 and at least partially fit with the two side surfaces of the purlin 200. There are two mounting portions 12, which are respectively disposed at one ends of the two side plates 112 away from the bottom plate 111. The two mounting portions 12 respectively extend in directions away from each other from the two side plates 112.

[0038] Please refer to Figure 2 、 Figure 5 、 Figure 6 As shown, the mounting portion 12 is provided with a first through hole 121, the connecting member 2 is provided with a second through hole 21, and the frame 101 is provided with a third through hole 102. The first through hole 121, the second through hole 21, and the third through hole 102 are axially corresponding. The fastener 3 passes through the first through hole 121, the second through hole 21, and the third through hole 102 to tightly connect the reinforcing member 1, the connecting member 2, and the frame 101.

[0039] Please refer to Figures 1 to 3 As shown, in this embodiment, the reinforcing member 1 is a symmetric structure. Preferably, the enclosing portion 11 has an upward opening 110, and the connecting member 2 covers the opening 110, which is convenient for installation.

[0040] Furthermore, the plane where the installation part 12 is located is not higher than the upper surface of the purlin 200. With such a setting, there is a certain gap between the installation part 12 and the frame 101 of the photovoltaic module 100. When the fastener 3 passes through the frame 101 and locks with the installation part 12, the gap between the installation part 12 and the frame 101 can be reduced to the minimum or they can be in mutual contact. The two can generate mutual tensile forces, which can press the frame 101 of the photovoltaic module onto the purlin 200, making the connection between the purlin 200 and the frame 101 of the photovoltaic module more firm and stable, thereby further strengthening the connection stability between the photovoltaic module 100 and the purlin 200, and there is no need to drill holes in the purlin 200 on site;

[0041] Or, when the fastener 3 locks and fixes the frame 101, the connecting member 2 and the reinforcing member 1, the gap between the connecting member 2 and the reinforcing member 1 can be reduced to the minimum or the two can be in mutual contact. The two can generate mutual tensile forces, which can press the frame 101 of the photovoltaic module onto the purlin 200, thereby further strengthening the connection stability between the photovoltaic module 100 and the purlin 200. Preferably, the plane where the installation part 12 is located is lower than the upper surface of the purlin 200.

[0042] Please refer to Figures 5 to 8 As shown, when the long side frame of the photovoltaic module 100 is installed parallel to the length direction of the purlin 200, that is, when the photovoltaic module 100 is placed vertically, the reinforcement structure of this embodiment can be used for the reinforcement and fixation of adjacent photovoltaic modules 100. That is, the two installation parts 12 of each reinforcing member 1 are respectively fixedly connected to the frames 101 of adjacent two photovoltaic modules 100. At this time, at least part of the lower surface of the frame 101 is in contact with the upper surface of the purlin 200 to achieve connection stability;

[0043] When the reinforcement structure includes the connecting member 2, the two installation parts 12 of each reinforcing member 1 are respectively fixedly connected to the frames 101 and the connecting members 2 of adjacent two photovoltaic modules 100.

[0044] Furthermore, the reinforcement structure of this embodiment can also be used for the reinforcement and fixation of the outer photovoltaic module 100. When used for the reinforcement and fixation of the outer photovoltaic module 100, one installation part 12 is fixedly connected to the frame 101 and the connecting member 2 of the outer photovoltaic module 100, and the other installation part 12 is directly fixedly connected to the connecting member 2.

[0045] In this embodiment, both the reinforcing member 1 and the connecting member 2 are made of rigid materials, specifically metal or alloy materials; the reinforcing member 1 is of an integral structure, and can be specifically formed by bending a sheet of material. The right angles formed by bending exist between the side plate 112 and the bottom plate 111, and between the mounting portion 12 and the side plate 112. In this way, it is not easy to damage the frame 101 and the purlin 200 during installation, and it is simple to manufacture and convenient to install. Since the distance between the frame 101 and the mounting portion 12 is small, the fastener 3 can use a short-head bolt to lock the frame 101 and the reinforcement structure, saving costs.

[0046] The reinforcement structure has a wide range of applications and can be applied to purlins of various different models such as U-shaped, C-shaped, Z-shaped, and square. While at least part of the reinforcing member 1 fits against the lower surface and the side surface of the purlin 200, when using the fastener 3 to lock the reinforcing member 1 to the frame 101 of the photovoltaic module 100, due to the support of the two side plates 112 of the reinforcing member 1, the purlin 200 will not be deformed due to the tensile force generated between the reinforcing member 1 and the frame 101. The reinforcing member 1 can be bent and formed according to the shape of the purlin 200 in actual applications, and cooperates with the connecting member 2 to completely surround the purlin 200, having a good fixing effect and connection stability.

[0047] When installing the photovoltaic support of this embodiment, first use the pressing block 300 to fix the base of the photovoltaic module 100 to the purlin 200, and then use the reinforcement structure to reinforce the connection between the photovoltaic module 100 and the purlin 200. When installing the reinforcement structure, first surround the outer periphery of the purlin 200 with the reinforcing member 1 from bottom to top, then place the connecting member 2 between the frame 101 and the purlin 200 to make the first through hole 121, the second through hole 21, and the third through hole 102 axially corresponding. Finally, use the fastener 3 to pass through the first through hole 121, the second through hole 21, and the third through hole 102 to lock and fix the frame 101, the connecting member 2, and the reinforcing member 1, so as to complete the secondary reinforcement and fixation of the photovoltaic module 100, which can avoid the situation that the photovoltaic module 100 is blown away due to the deformation and failure of the pressing block 300, and the situation that other non-deformed pressing blocks are also pulled and deformed and failed due to the blowing away of the photovoltaic module 100, effectively protecting the photovoltaic module 100 and the pressing block 300.

[0048] In summary, compared with the prior art, the reinforcement structure of the photovoltaic module and the photovoltaic support of the present utility model have the following advantages: The inverted "r" shaped reinforcement member 1 is adopted. The reinforcement member 1 can cooperate with the connecting member 2. The reinforcement member 1 surrounds the outer periphery of the purlin 200 and at least partially fits with the lower surface and the side surface of the purlin. The connecting member 2 is arranged between the photovoltaic module 100 and the purlin 200. The frame 101 of the photovoltaic module 100 is fixedly connected to the connecting member 2 and the reinforcement member 1 through the fastener 3. Thus, on the basis of fixing and installing the photovoltaic module 100 on the purlin 200 by using the pressing block 300, the photovoltaic module 100 is secondarily reinforced and fixed, which can effectively avoid the situation that the photovoltaic module 100 is blown away due to the deformation and failure of the pressing block 300, and further avoid the situation that the non-deformed pressing block 300 is also pulled and deformed and fails due to the blowing away of the photovoltaic module 100, playing a certain protective role for the pressing block 300. The reinforcement structure of the photovoltaic module and the photovoltaic support have safe and stable structures, convenient installation, low cost and strong practicability.
