[0025] Next, exemplary embodiments according to the present application will be described in more detail with reference to the drawings. It should be noted that these exemplary embodiments can be implemented in many different forms and should not be construed as being limited only to the embodiments described herein.

[0026] An embodiment of the present application provides an installation jig for a photovoltaic module, which is used to fix the photovoltaic module and fix the photovoltaic module on the purlin of a photovoltaic installation bracket, so as to fixedly install the photovoltaic module in an outdoor application scenario. Figure 1 The structural schematic diagram of the installation jig provided by the embodiment of the present application is shown, as Figure 1 shown, the installation jig includes a clamping member 100 and a pressing member 200. Figure 2 The structural schematic diagram of the clamping member 100 provided by the embodiment of the present application is shown. Figure 3 The structural schematic diagram of the pressing member 200 provided by the embodiment of the present application is shown.

[0027] As Figures 2 to 3 shown, the clamping member 100 is used to clamp and fix the photovoltaic module. The photovoltaic module generally includes an aluminum frame surrounding the periphery. The clamping member 100 clamps the aluminum frame to facilitate the fixed installation of the photovoltaic module. The clamping member 100 includes a first fixing block 110, an intermediate plate 120 and a second fixing block 130 fixedly connected in sequence. The intermediate plate 120 has a bent portion 121 bent toward the second fixing block 130. A clamping groove 131 is formed between the bent portion 121 and the second fixing block 130. The clamping groove 131 is used to clamp the photovoltaic module. A rib is provided in the clamping groove 131 so that the rib cooperates with the groove on the aluminum frame. The photovoltaic module can be inserted into the clamping groove 131 from the side and pushed along the rib, so that the photovoltaic module is clamped in the clamping groove 131 and firmly clamped. Further, the outer edge of the bent portion 121 can be bent toward the second fixing block 130 to tighten the opening of the clamping groove 131, so that the outer edge of the bent portion 121 can abut against the aluminum frame of the photovoltaic module to firmly clamp the photovoltaic module.

[0028] The upper side surface 102 of the first fixing block 110 is inclined downward toward the intermediate plate 120, forming a first inclined groove 101 with the intermediate plate 120. The first fixing block 110 can be used to fix the clamping member 100 on the purlin 400 of the installation bracket. The clamping member 100 can be fixed by pressing from above the first fixing block 110.

[0029] In the embodiment of the present application, the upper side surface 102 of the first fixing block 110 is inclined downward toward the intermediate plate 120, and the height of the intermediate plate 120 is higher than the height of the first fixing block 110, so that a first inclined groove 101 is formed between the upper side surface 102 of the first fixing block 110 and the intermediate plate 120.

[0030] The pressing member 200 is used to press the first fixing block 110 from the upper side surface 102 of the first fixing block 110, so that the clamping member 100 can be fixed on the purlin 400 of the mounting bracket. The pressing member 200 includes a bottom plate, a first convex block 210 disposed in the middle of the bottom plate, and two lugs 220 disposed on both sides of the first convex block 210. The bottom plate forms the pressing body of the pressing member 200, which connects the first convex block 210 and the two lugs 220. The first convex block 210 and the two lugs 220 are used to achieve the functions of limiting and pressing. The middle part of the bottom plate can be a part of the first convex block 210, and both sides can also belong to a part of the lugs 220 respectively. That is, the bottom plate can be the connecting area where the first convex block 210 and the two lugs 220 are connected to each other, and it is not necessary to have a plate-like structure. The bottom plate, the first convex block 210 and the lugs 220 are of an integral structure, and an approximate T-shape is formed after integral molding. The lugs 220 are hung on the first fixing block 110 in two opposite clamping members 100. By pressing the first convex block 210, the two clamping members 100 can be pressed and fixed. The lower side surface 221 of the lug 220 inclines towards the bottom plate along the direction towards the first convex block 210, forming a second inclined groove 201 with the first convex block 210; the second inclined groove 201 is adapted to the first inclined groove 101, so that when the lug 220 is hung on the first fixing block 110, the first inclined groove 101 and the second inclined groove 201 are fitted.

[0031] As Figures 1 to 5 shown, in the embodiment of the present application, by fitting the first inclined groove 101 and the second inclined groove 201, at least two contact surfaces are formed. When the photovoltaic module is subjected to upward or downward wind force, the photovoltaic module drives the clamping member 100 to have a rotational force of upward or downward inclination. In the first contact surface 501, based on the characteristics of its inclined surface, the lug 220 has an acting force in the inclined direction on the first fixing block 110, which can be used to resist the rotational force, thereby enhancing the wind resistance.

[0032] In one example, the photovoltaic module is subjected to an upward wind force or an upward and leftward inclined wind force, Figure 4 and the photovoltaic module on the right side in the figure has a tendency to rotate counterclockwise upward and leftward. The force of the second contact surface 502 will resist the leftward rotation of the middle plate 120. At the same time, in the first contact surface 501, there is a force that inclines downward and leftward to resist the upward and leftward force. Compared with the setting where the upper side surface 102 is flush, this inclined setting method cancels more of the acting force of the wind, and thus has stronger wind resistance.

[0033] In one example, the photovoltaic module is subjected to a downward wind force. The clamping member 100 on the right side in the figure has a tendency to rotate clockwise to the right. In the first contact surface 501, there is a downward and leftward resistance force to resist the rightward rotation of the first fixing block 110.

[0034] The cooperation between the first inclined groove 101 and the second inclined groove 201 can also limit the distance between two opposite clamping members 100, so as to ensure that the side of the hanging ear 220 is in contact with the middle plate 120, thereby generating a mutual acting force on the second contact surface 502; further, it can also ensure that the first convex block 210 is in contact with the first fixing block 110, so as to generate a mutual acting force on the third contact surface 503.

[0035] In the embodiment of the present application, through the cooperation between the first inclined groove 101 and the second inclined groove 201, better mechanical properties are provided to resist strong winds and the wind resistance ability is improved.

[0036] In one embodiment, the angle of the first inclined groove 101 is 15° - 75°, and the depth of the first inclined groove 101 is 3 - 10 cm.

[0037] The angle of the first inclined groove 101 can be understood as the included angle formed by the upper side surface 102 of the first fixing block 110 and the middle plate 120. The upper side surface 102 of the first fixing block 110 needs to have a certain inclination to provide a force in the inclined direction to resist strong winds. The middle plate 120 can be vertically arranged, and the vertical arrangement here can be understood as being perpendicular to the purlin 400. Therefore, a first inclined groove 101 is formed between the inclined upper side surface 102 of the first fixing block 110 and the middle plate 120. The angle of the first inclined groove 101 depends on the inclined setting angle of the first fixing block 110.

[0038] The angle of the first inclined groove 101 can be set according to the climate environment of the photovoltaic module installation location. In areas with stronger winds, a smaller inclination angle can be set, that is, the upper side surface 102 of the first fixing block 110 is set closer to the middle plate 120; in areas with weaker winds, a larger inclination angle can be set.

[0039] The angle of the first inclined groove 101 cannot be too small, otherwise the width of the hanging ear 220 will be too thin, affecting the pressing effect of the pressing member 200, resulting in insufficient downward pressure to resist strong winds.

[0040] If the angle of the first inclined groove 101 is too large, the resistance in the inclined direction will be insufficient, and it is difficult to achieve the effect of resisting strong winds.

[0041] Therefore, in the embodiment of the present application, the angle of the first inclined groove 101 is limited to 15° - 75°, for example, 15°, 30°, 50°, 60° or 75° are all feasible. Preferably, the angle of the first inclined groove 101 can be limited to 30° - 70° to ensure the strong wind resistance effect of the photovoltaic module.

[0042] Similarly, if the depth of the first inclined groove 101 is too deep, the depth of the hanging ear 220 needs to be relatively deep to fit with the first inclined groove 101, which will result in a relatively wide width of the hanging ear 220, causing a relatively large distance between the two opposite clamping members 100 and wasting the space on the purlin 400. If the depth of the first inclined groove 101 is too shallow, the resistance of the hanging ear 220 to the inclined direction is insufficient, and it is difficult to achieve the effect of resisting strong winds.

[0043] Therefore, in the embodiment of the present application, the angle of the first inclined groove 101 is limited to 3 - 10 cm, and for example, 3 cm, 4 cm, 6 cm, 10 cm are all feasible.

[0044] In one embodiment, the lower edge of the upper side surface 102 of the first fixing block 110 is lower than the height of the second fixing block 130, and the upper edge of the upper side surface 102 of the first fixing block 110 is higher than the height of the second fixing block 130.

[0045] The upper side surface 102 of the first fixing block 110 is inclined, so the heights of the two edges of the upper side surface 102 of the first fixing block 110 are different. The higher one is the upper edge, and the lower one is the lower edge.

[0046] It can be known that when the photovoltaic module rotates, it takes the second fixing block 130 as the fulcrum. In the embodiment of the present application, by making the upper edge higher than the height of the second fixing block 130 and the lower edge lower than the height of the second fixing block 130, the force at the center position of the first contact surface 501 can resist the rotational force of the photovoltaic module, enhancing the resistance effect. It can also make the force on the second contact surface 502 act on both the second fixing block 130 and the photovoltaic module simultaneously, further enhancing the resistance effect.

[0047] In one embodiment, the height by which the first convex block 210 protrudes from the hanging ear 220 is 1 / 4 - 1 / 2 of the height of the first fixing block 110.

[0048] The height by which the first convex block 210 protrudes from the hanging ear 220 can be the height by which it protrudes from the lower edge of the hanging ear 220.

[0049] The first convex block 210 needs to protrude from the hanging ear 220 so that the first convex block 210 is clamped between the two opposite clamping members 100, generating a horizontal resistance force on the two clamping members 100. If the height by which the first convex block 210 protrudes from the hanging ear 220 is too low, it is difficult to generate sufficient resistance force in the horizontal direction.

[0050] The first convex block 210 can extend to abut against the purlin 400 or be close to the purlin 400, but such a structure will consume more material costs and is not convenient for pressing the first fixing block 110.

[0051] The height by which the first bump 210 protrudes from the ear 220 is 1 / 4 to 1 / 2 of the height of the first fixing block 110, and for example, it can be 1 / 4, 1 / 3 or 1 / 2.

[0052] In one embodiment, when the ear 220 is hung on the first fixing block 110, the height of the bottom plate is higher than or flush with the height of the bending portion 121.

[0053] In the embodiment of the present application, the bottom plate of the pressing member 200 presses on the first fixing block 110 instead of the bending portion 121, which can avoid damaging the photovoltaic module under a large pressing force.

[0054] The height of the bottom plate being higher than or flush with the height of the bending portion 121 can ensure the abutment of the ear 220 and the middle plate 120, so that mutual acting forces are generated at the position of the second contact surface 502, and the acting area of the acting forces is large, providing stronger wind resistance.

[0055] In one embodiment, it further includes a locking bolt 300. The pressing member 200 is provided with a first bolt hole 202 penetrating through the bottom plate and the first bump 210. The clamping member 100 is disposed on the purlin 400 of the photovoltaic bracket, and the purlin 400 is provided with a second bolt hole; the two ears 220 of the pressing member 200 are respectively hung on two relatively arranged clamping members 100, and the locking bolt 300 passes through the first bolt hole 202 and the second bolt hole and is locked.

[0056] In the embodiment of the present application, the pressing member 200 is tightly fixed to the purlin 400 through the locking bolt 300, thereby fixing the clamping member 100 on the purlin 400.

[0057] In the embodiment of the present application, as Figure 3 shown, the clamping member 100 is a long strip-shaped sheet metal part to completely clamp the entire frame of the photovoltaic module and clamp the photovoltaic module stably. The first fixing block 110, the middle plate 120 and the second fixing block 130 in the clamping member 100 can be integrally formed.

[0058] In the pressing member 200, the bottom plate, the first protruding portion and the ear 220 can be integrally formed. Among them, the ear 220 and the first protruding portion can adopt a hollow structure design. For example, as Figure 3 shown in the hollow structure, it can reduce the mass of the pressing member 200 and lower the material cost while providing resistance.

[0059] The length of the pressing member 200 can be less than that of the clamping member 100. Two to six pressing members 200 can be arranged on one clamping member 100, that is, the clamping member 100 is fixed to the purlin 400 by 2-6 bolts 300. The 2-6 pressing members 200 are evenly distributed on the clamping member 100. For example, in the case of two pressing members 200, they can be respectively arranged at the head end and the tail end of the clamping member 100.

[0060] In one embodiment, the first fixing block 110 or the second fixing block 130 is a ribbed plate block with a hollow structure.

[0061] In the first fixing block 110, the pressing member 200 presses on the upper side 102 of the first fixing block 110, so as to achieve the effect of pressing the clamping member 100. Therefore, the first fixing block 110 only needs to have a stable or firm upper side 102, and the rest of the structure can be not limited. By setting the first fixing block 110 with a hollow structure, the structure of the first fixing block 110 can be made stable, so that the upper side 102 has a certain height, or the height of the upper side 102 can be set according to requirements, and the consumption of materials can be reduced, and the weight of the clamping member 100 can be reduced.

[0062] Similarly, in the second fixing block 130, a clamping groove 131 is formed between the upper side of the second fixing block 130 and the bending part 121 to clamp the photovoltaic module. Therefore, the second fixing block 130 only needs to have a stable or firm upper side, and the rest of the structure can be not limited. By setting the second fixing block 130 with a hollow structure, the structure of the second fixing block 130 can be made stable, so that the upper side of the second fixing block 130 has a certain height, or the height of the upper side of the second fixing block 130 can be set according to requirements, and the consumption of materials can be reduced, and the weight of the clamping member 100 can be reduced.

[0063] In the embodiment of the present application, in order to further enhance the application of the photovoltaic module in extreme environments, a reinforcing layer can also be added inside the photovoltaic module. The reinforcing layer is arranged in the adhesive film between the backboard glass and the battery cells. The reinforcing layer divides the adhesive film into two adhesive films, and the two adhesive films are respectively located on opposite sides of the reinforcing layer.

[0064] The reinforcing layer can be a TPU (Thermoplastic polyurethanes) adhesive film or a PVB (PolyVinylButyral Film) adhesive film.

[0065] The embodiment of the present application also provides a mounting bracket for a photovoltaic module, including a purlin 400 and a mounting jig in any implementation aspect of the above embodiment. The cooperation between the purlin 400 and the mounting jig is as described above.

[0066] In one embodiment, the purlin 400 is provided with a second bolt hole. On the side of the purlin 400 facing away from the installation jig, a second protrusion 410 is provided, and the second bolt hole passes through the second protrusion 410.

[0067] In the embodiment of the present application, by providing the second protrusion 410 on the purlin 400, when the nut is tightened, it can be locked with a greater force, so that the nut is tightly screwed on the second protrusion 410. The second protrusion 410 can withstand a greater pressure, so that the pressing member 200 and the purlin 400 are firmly locked, further improving the strong wind resistance.

[0068] In one embodiment, the clamping member 100 in the installation jig is fixed to the purlin 400 by threads, and the fixing bolt passes through the hollow position of the first fixing block 110 or the second fixing block 130 to the purlin 400.

[0069] Based on the hollow setting of the first fixing block 110 or the second fixing block 130, the fixing bolt can be screwed in from the edge of the clamping member 100. The fixing bolt passes through the bottom of the first fixing block 110 or the second fixing block 130 and the purlin 400, and is tightened and fixed by a nut from the direction of the purlin 400 facing away from the clamping member 100, further enhancing the stability of the clamping member 100, thereby improving the strong wind resistance of the photovoltaic module.

[0070] The embodiment of the present application further provides a photovoltaic system, including: a plurality of photovoltaic modules, and the plurality of photovoltaic modules are installed on the installation bracket according to any one of the above embodiments.
