[0028] Please refer to Figures 1 to 10 As shown, the utility model discloses a photovoltaic fixing part 100, which is used to fix a photovoltaic assembly (i.e., a photovoltaic panel 200) on the main shaft 300 of a photovoltaic bracket, and includes a pressing block 1, a purlin 2, and a fastener 3. The pressing block 1 is used to be crimped with the upper surface of the photovoltaic panel 200, and the purlin 2 is used to abut against the lower surface of the photovoltaic panel 200. The fastener 3 is used to fix the pressing block 1 and the purlin 2 to the main shaft 300. The fastener 3 connects the pressing block 1 and the purlin 2. By adjusting the fastener 3, the photovoltaic panel 200 can be fixed on the main shaft 300 where the photovoltaic panel 200 is to be installed. The utility model also discloses a photovoltaic combination structure, and the photovoltaic combination structure of the utility model includes the above-mentioned photovoltaic fixing part 100. The photovoltaic fixing member 100 includes a pressing block 1 and a purlin 2 connected by a fastener 3. The pressing block 1 and the purlin 2 are respectively on opposite sides of the photovoltaic panel 200, and the pressing block 1 and the purlin 2 clamp the photovoltaic panel 200 together. Compared with the prior art, the photovoltaic combination structure of the utility model includes a photovoltaic fixing member 100, and the photovoltaic fixing member 100 includes a pressing block 1, a purlin 2 and a fastener 3; the photovoltaic panel 200 is fixed on the main shaft 300 by passing the fastener 3 through the pressing block 1 and the purlin 2, so the assembly positioning can be completed by adjusting the fastener 3, and the assembly is fast and convenient with high connection strength.
[0029] Please refer to Figure 1 and Figure 2, the pressing block 1 includes a bottom 11, a pair of side portions 12 vertically and identically bent and extended from both sides of the bottom 11, and a pair of wing portions 13 reversely bent and extended from the ends of the pair of side portions 12. The fastener 3 passes through the bottom 11 to press the pair of wing portions 13 against the upper surface of the photovoltaic panel 200. That is to say, the cross-section of the pressing block 1 in the left-right direction shown in Figure 1 is in a "J" shape.
[0030] Please refer to Figure 1 and Figure 2 , the purlin 2 includes a bottom wall 21, a pair of side walls 22 vertically and identically bent and extended from both sides of the bottom wall 21, and a pair of wing walls 23 reversely bent and extended from the ends of the pair of side walls 22. The fastener 3 passes through the bottom wall 21 to make the pair of wing walls 23 abut against the lower surface of the photovoltaic panel 200. That is to say, the cross-section of the purlin 2 in the left-right direction is also in a "J" shape. By setting the structure of the pressing block 1 to be the same "J" shape as that of the purlin 2, the pressing block 1 can be processed through the production line of the purlin 2 without the need to design and develop new molds or processes additionally, which is convenient for industrialization and low-cost processing.
[0031] Therefore, please refer to Figures 1 to 6 , a first chamber 10 is formed between the bottom 11 and the pair of side portions 12, and a second chamber 20 is formed between the bottom wall 21 and the pair of side walls 22. Please refer particularly to Figure 3 , the second chamber 20 has an opening (not labeled) corresponding to the bottom wall 21 up and down; the width dimension W1 of the bottom 11 in the transverse direction is smaller than the width dimension W2 of the opening in the transverse direction, and the bottom 11 can smoothly enter the second chamber 20 through the opening. That is to say, the first "J" shape of the cross-section of the pressing block 1 in the left-right direction shown in Figure 1 (in combination with referring to the upper "J" shape in Figure 3 ) can pass through the opening, and at least part of it can fall into the second "J" shape of the cross-section of the purlin 2 in the left-right direction shown in Figure 1 (in combination with referring to the lower "J" shape in Figure 3 ). It can be understood that the height at which the two "J" shapes fall in the up-down direction, that is, the range of the numerical value that the fastener 3 can adjust.
[0032] Please refer to Figures 4 to 6 shown, the height dimension H1 of the side portion 12 in the vertical direction is greater than the height dimension H2 of the side wall 22 in the vertical direction, and the wing portions 13 are correspondingly arranged above the wing walls 23 and there is always a distance between the wing portions 13 and the corresponding wing walls 23. Specifically, it can be understood that in Figure 5In the first state of the initial assembly of the pressing block 1 and the purlin 2 shown, the spacing distance between the flying wing portion 13 and the wing fin wall 23 is D1; in Figure 6 In the second state where the pressing block 1 and the purlin 2 shown are assembled in place, the spacing distance between the flying wing portion 13 and the wing fin wall 23 is D2 and D2 < D1. The effect of D2 < D1 is that it ensures that the height difference value by which at least part of the first "Ji" shape can fall into the second "Ji" shape via the opening is D1 - D2. That is, in the present invention, the height difference value is adapted to the thickness of the photovoltaic panel 200 for better clamping and fixing.
[0033] Please refer to Figure 1 , Figure 2 and Figure 7 , Figure 8 , the present invention further includes a connecting plate 4. There are two fasteners 3 in the photovoltaic fixing member 100. In a specific embodiment, the fastener 3 includes a bolt 31 and a nut 32, that is, there are two bolts 31 and two nuts 32. The fasteners 3 are arranged front and back on opposite sides of the main shaft 300; the connecting plate 4 connects the fasteners 3 together below the main shaft 300. Please refer to Figure 8 , by means of the connecting plate 4, the photovoltaic fixing member 100 of the present invention realizes a closed-loop space, and thus can be fixedly sleeved on the main shaft 300.
[0034] Please refer to Figure 2 , the fastener 3 includes a bolt 31 and a nut 32. In a specific embodiment, the bolt 31 is a straight type including a head 311 and a rod portion 312. The rod portion 312 of the bolt 31 penetrates through the pressing block 1 and the purlin 2, and the nut 32 is sleeved on the rod portion 312 of the bolt 31. By adjusting the screwing degree of the nut 32 on the rod portion 312 of the bolt 31 relative to the head 311, the pressing block 1 and the purlin 2 can be tightened or loosened. It can be understood that, please refer to Figure 2 and Fig.10, screw the nut 32 to make it move upward relative to the head 311, and the nut 32 gradually compresses the pressing block 1 and the purlin 2 in the process of getting closer and closer to the head 311, so as to clamp the photovoltaic panel 200; conversely, screw the nut 32 to make it move downward relative to the head 311, and the nut 32 gradually loosens the pressing block 1 and the purlin 2 in the process of getting farther and farther away from the head 311, so as to release the photovoltaic panel 200. In other embodiments not shown in the figure, the fastener 3 can also be a single U-bolt, and locking the U-bolt in the first chamber 10 of the pressing block 1 can also fix the pressing block 1 and the purlin 2. Therefore, it can be understood that the present invention does not limit the form of the bolt 31.
[0035] Please refer to Figure 2 , Figure 5 and Figure 6 The utility model further includes a gasket plate 5. The gasket plate 5 is clamped between the head 311 of the bolt 31 and the bottom 11 of the pressing block 1, and its function is to relieve the pressure; the connecting plate 4 can be clamped between the nut 32 and the main shaft 300, so as to achieve the fixing function of the photovoltaic fixing member 100 of the utility model on the main shaft 300.
[0036] The utility model relates to a photovoltaic combination structure, which includes a photovoltaic panel 200 and a main shaft 300. The key point is that the photovoltaic combination structure of the utility model also includes the photovoltaic fixing member 100 as described above.
[0037] In summary, compared with the prior art, the photovoltaic combination structure of the utility model includes a photovoltaic fixing part 100, and the photovoltaic combination structure of the utility model includes a photovoltaic fixing part, and the photovoltaic fixing part includes a pressing block, a purlin and a fastener; the pressing block 1 and the purlin 2 are respectively on opposite sides of the photovoltaic panel 200, and the pressing block 1 and the purlin 2 clamp the photovoltaic panel 200 together, and then the photovoltaic component is fixed to the purlin through the fastener, and the cooperation of the two improves the connection strength between the photovoltaic component and the purlin; the fastener includes a bolt and a nut, and the photovoltaic panel 200 is fixed to the main shaft 300 by passing the bolt 31 through the pressing block 1 and the purlin 2. Therefore, the structure of the utility model is simple, and when adjusting the fastener 3, it is only necessary to tighten the nut 32 below to complete the assembly positioning, and the assembly is fast and convenient with high connection strength.
