[0029] In a specific embodiment, this embodiment provides a BIPV roof photovoltaic module fixing device, which is mainly used to fix the photovoltaic module 2 to the tile 1. Specifically, the BIPV roof photovoltaic module fixing device mainly includes an intermediate connector 4, a clamp 5, a support 6 and a fastener 3.

[0030] The support 6 is used for fixed installation on the tile 1, and the fastener 3 is used for clamping on the outer protrusion of the photovoltaic component 2 along the inner and outer directions. The fastener 3 is clamped on the protrusion along the inner and outer directions, which means that the depth direction of the groove 31 on the fastener 3 for clamping on the protrusion is the inner and outer direction. The photovoltaic component 2 is fixed in the lateral direction by clamping on the protrusion through the groove 31. For the convenience of description, the inside and outside referred to here and in the context refers to the stacking direction of the tile 1 and the photovoltaic component 2, wherein the photovoltaic component 2 is stacked on the outside of the tile 1. The fastener 3 is buckled on the photovoltaic component 2 from the outside of the photovoltaic component 2, which not only limits the lateral movement of the photovoltaic component 2 through the groove 31, but also limits the outward movement of the photovoltaic component 2 through the fastener 3. The inner side of the photovoltaic component 2 can directly or indirectly abut against the tile 1, so that the fastener 3 can buckle the photovoltaic component 2 on the tile 1.

[0031] The inner and outer sides of the intermediate connecting member 4 are rotatably connected to the support 6 and the fastener 3, respectively, so that the intermediate connecting member 4 can rotate relative to the support 6, and the fastener 3 can rotate on the basis of the intermediate connecting member 4. The intermediate connecting member 4 in this structure is like a crank in a crank slider mechanism, and the fastener 3 is like a connecting rod connected between the crank and the slider in the crank slider mechanism, so that when the position of the fastener 3 relative to the support 6 is restricted, the rotation between the fastener 3 and the intermediate connecting member 4 is prevented, and at the same time the rotation between the intermediate connecting member 4 and the support 6 is restricted, thereby achieving fixation.

[0032] Specifically, after the installation is completed, one side of the fastener 3 in the rotation direction is used to press on the outside of the photovoltaic component 2, and the other side is against the clamp 5 fixedly installed on the bracket to limit the rotation of the intermediate connector 4 relative to the support 6 and relative to the fastener 3, so as to keep the fastener 3 in the current clamping position. The fastener 3 is limited from both sides of the rotation direction by the photovoltaic component 2 supported and fixed by the tile 1 and the clamp 5 fixed on the support 6, so that the fastener 3 cannot rotate. Because of the limitation of the intermediate connector 4, the end of the intermediate connector 4 connected to the fastener 3 cannot rotate, so that the fastener 3 cannot move or rotate, so that the fastener 3 and the support 6 remain relatively fixed.

[0033] In the BIPV roof photovoltaic component fixing device, during installation, the photovoltaic component 2 is placed on the tile 1 so that the inner side of the photovoltaic component 2 directly or indirectly rests on the tile 1. Then the support 6 is placed, and the hinged connection between the intermediate connector 4 and the support 6 and the fastener 3 is assembled, and then the hinge shafts at both ends of the intermediate connector 4 are rotated so that the card slot 31 of the fastener 3 moves toward the raised portion on the outer side of the photovoltaic component 2, and moves in the inner and outer directions at the raised portion to be stuck on the raised portion of the photovoltaic component 2, and the fastener 3 is pressed on the outer side of the photovoltaic component 2. Then the card 5 is installed so that the card 5 pushes the fastener 3 from the other side of the rotation direction so that the fastener 3 cannot be deflected in the reverse direction, and then the card 5 is fixed, thereby completing the fixing of the photovoltaic component 2. In the BIPV roof photovoltaic component fixing device, the fastener 3 is used to press the outer side of the photovoltaic component 2 to cooperate with the bearing of the tile 1, so that the photovoltaic component 2 can be fixed well. The fastener 3 and the support 6 are fixed by an intermediate connector 4 with hinged ends, and a clamp 5 is used to limit the rotation of the fastener 3 relative to the intermediate connector 4, so that the fastener 3 can be well pressed to maintain the buckling of the fastener 3. This buckling method ensures the buckling pressure between the fastener 3 and the photovoltaic module 2, thereby ensuring the buckling effect. In summary, the BIPV roof photovoltaic module fixing device can effectively solve the problem of poor fixing effect of the photovoltaic module 2.

[0034] In order to facilitate disassembly and assembly, it is preferred here that the intermediate connector 4 and the support 6 as well as the fastener 3 are rotationally connected by a longitudinally extending cylinder 7 and a semicircular groove 8 rotatably matched with the cylinder 7, so that during installation, force is transmitted between the cylinder 7 and the bottom of the semicircular groove 8 to push the fastener 3 onto the photovoltaic component 2. This allows the intermediate connector 4 to be assembled with the support 6 and the fastener 3 later during assembly.

[0035] Specifically, in order to facilitate the application of thrust, the fastener 3 is preferably L-shaped, that is, the fastener 3 is formed by two folding sections arranged vertically and connected. One of the folding sections of the fastener 3 extends inward, that is, the inner folding section, and the inner end of the inner folding section is rotatably connected to the intermediate connector 4, while the other folding section of the fastener 3 extends laterally, that is, the lateral folding section, which extends laterally toward the photovoltaic component 2 and is provided with a slot 31 with an opening facing inward at the end for matching with the protruding portion of the photovoltaic component 2, and for the convenience of engagement, the depth of the slot wall of the slot 31 close to its inner folding section can be made smaller than the depth of the slot wall away from its inner folding section, wherein the depth of the slot wall is the length of the slot wall in the inner and outer directions. By making the fastener 3 L-shaped, the clamp 5 can push the fastener 3 laterally, so that the fastener 3 is pressed inward on the photovoltaic component 2, and at this time, the clamp 5 is like a wedge that is clamped inward to the lateral side of the fastener 3.

[0036] Furthermore, in order to facilitate the installation of the fastener 3, the support 6 is preferably in a groove shape with an opening facing outward, and the intermediate connector 4 and the inner extension section of the fastener 3 are both located in the groove cavity of the support 6, wherein the groove of the support 6 has a first folding plate extending inwardly to be rotatably connected with the intermediate connector 4, so that the intermediate connector 4 and the first folding plate transmit resistance inwardly and outwardly in the installed state. The inner end of the inner extension section of the fastener 3 has a second folding plate extending outwardly to be arranged opposite to the first folding plate, and the second folding plate is rotatably connected to the intermediate connector to transmit resistance in the inner and outer directions, and the inner extension section of the fastener 3, which is away from the intermediate connector 4, resists against the clamp 5. At this time, the inner side of the transverse fold section of the intermediate connecting member 4 can be made to abut against the outer end face of the slot wall of the support 6. It should be noted that the distance between the slot wall plate close to the inner extension fold section in the above-mentioned slot 31 and the inner extension fold section is slightly larger than the width of the slot edge of the support 6, so that the slot edge can be inserted into the slot cavity formed between the slot 31 and the inner extension fold section, and there is a certain movable gap in the transverse direction to avoid mutual interference, thereby ensuring that the fastener 3 is buckled into place.

[0037] As described above, the intermediate connector 4 is rotatably connected with the support 6 and the fastener 3 through the cylinder 7 and the semicircular groove 8. The intermediate connector 4 may be provided with cylinders 7 on both the inner and outer sides, and the support 6 and the fastener 3 may be provided with semicircular grooves 8 correspondingly. Alternatively, one of the inner and outer sides of the intermediate connector 4 may be provided with cylinders 7 and the other may be provided with semicircular grooves 8, and one of the support 6 and the fastener 3 may be provided with semicircular grooves 8 correspondingly, and the other may be provided with cylinders 7. For the convenience of setting, it is preferred that the intermediate connector 4 is provided with semicircular grooves 8 on both the inner and outer sides, and the cylinders 7 are provided on the first folding plate and the second folding plate. The diameters of the cylinders 7 on the first folding plate and the second folding plate may be equal, and the first folding plate and the second folding plate may be connected to the middle of the cylinder 7.

[0038] Furthermore, considering that multiple photovoltaic modules 2 are generally required to be arranged side by side in the lateral direction, for the convenience of installation, it is preferred that fasteners 3 are arranged on both lateral sides of the clamp 5, and the clamp 5 can be inserted between the fasteners 3 on both sides along the inner and outer directions to abut against the fasteners 3 on both sides, just like a wedge is embedded between the two fasteners 3 to push the fasteners 3 on both sides to buckle the photovoltaic modules 2 on both sides. It should be noted that the fasteners 3 on both sides are connected to the notches on both sides of the support 6 by intermediate connectors 4, and can be arranged symmetrically on both sides.

[0039] Furthermore, in order to facilitate installation, the semicircular groove 8 is generally open at both ends in the longitudinal direction. In order to prevent the cylinder from detaching from the semicircular groove along the longitudinal direction, it is preferred here that limit baffles 51 are provided on both lateral sides of the end faces of both ends of the clamp 5 to prevent the cylinder 7 from detaching from the semicircular groove 8 in the longitudinal direction.

[0040] Further, in order to facilitate the installation of the support 6 and the shoulder, it is preferred that the inner end of the support 6 has a limiting groove 61 that matches the tile 1, wherein the shape of the limiting groove 61 is set according to the corresponding convex strip on the tile, such as the attached Figure 5 The trapezoidal limiting groove shown in the figure can also be as shown in the figure. Figure 6 The angle limit groove shown in the figure can also be as shown in the figure. Figure 7 The Butler limit groove shown. A connecting rod 9 is penetrated in the transverse middle part of the clamp 5, and the inner end of the connecting rod 9 passes through the support 6 for connection with the tile 1. The connecting rod 9 can be a screw or a bolt. The clamp 5 is pushed inward by the connecting rod 9 to ensure that the shoulder is embedded between the two fasteners 3 to ensure the buckling effect of the two fasteners 3. In order to ensure the buckling effect, it is preferred here that when the fastener 3 is buckled on the photovoltaic component 2, the outer end of the inner extension section of the fastener 3 is biased toward its corresponding photovoltaic component 2 compared to the inner end, so as to be arranged in an inclined state.
