Description

Technical Field

[0002] Building Integrated Photovoltaic (BIPV) uses photovoltaic modules as building components or building materials, making them part of the building and also having the function of generating electricity. BIPV can avoid occupying too much land resources, which is especially important for urban buildings where land is expensive. BIPV converts solar energy into electrical energy, which can reduce the overall outdoor temperature, and at the same time can play a peak-shaving role in the power grid, achieving the effect of building energy conservation.

[0003] There are basically two ways to lay photovoltaic roofs. One is a flat-laying structure, that is, adjacent photovoltaic tiles are laid flat; the other is an overlapped structure, that is, adjacent photovoltaic tiles are laid overlapping. Among them, the flat-laying structure currently usually sets a guide rail bracket fixed to the metal tiles on the roof under the photovoltaic module to support the photovoltaic module to be laid flat on top of the metal tiles. However, due to the large spacing between the guide rail brackets, the photovoltaic modules between the guide rail brackets are suspended. Therefore, during installation and maintenance, workers should avoid stepping on the photovoltaic modules to prevent damage to the photovoltaic modules; further, it is necessary to set up maintenance passages between the photovoltaic modules for workers to walk, resulting in the photovoltaic modules being unable to cover the entire roof.

DETAILED DESCRIPTION

[0030] Below, the present application is further described in conjunction with specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0031] In the description of the present application, it should be noted that directional words, such as the terms "center", "lateral", "longitudinal", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", etc., indicating directions and positional relationships are based on the directions or positional relationships shown in the accompanying drawings, which are only for the convenience of narrating the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and cannot be understood as limiting the specific scope of protection of the present application.

[0032] It should be noted that the terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0033] One or more embodiments of the present application disclose a photovoltaic assembly 4 clamping device 1 for mounting the photovoltaic assembly 4 on a metal tile 2. Figures 1 to 4 , including a fixing member 20, a pressing member 30 and a fastener 40. The fixing member 20 is suitable for being installed on the metal tile 2, and the fixing member 20 has a bearing surface 211 for receiving the photovoltaic module 4. When the fixing member 20 is installed on the metal tile 2, the supporting height of the bearing surface 211 is consistent with the supporting height of the metal tile 2, so that the bearing surface 211 and the tile rib 82 of the metal tile 2 jointly support the photovoltaic module 4; the pressing member 30 is suitable for being installed on the fixing member 20, and a clamping area 10 is formed between the pressing member 30 and the bearing surface 211 to clamp the photovoltaic module 4; the fastener 40 detachably connects the pressing member 30 and the fixing member 20.

[0034] That is to say, when the photovoltaic component 4 is installed in the clamping area 10 of the clamping device 1, the bearing surface 211 of the fixing part 20 is able to support the photovoltaic component 4, and the back side of the photovoltaic component 4 is abutted against the tile rib 82 of the metal tile 2, so that the bearing surface 211 and the tile rib 82 of the metal tile 2 can support the photovoltaic component 4 at the same time, which is beneficial to improve the bearing capacity of the photovoltaic component 4. During installation and maintenance, the staff can directly step on the photovoltaic component 4 without setting up maintenance passages between the photovoltaic components 4, so that the photovoltaic components 4 can cover the entire roof, thereby increasing the power generation.

[0035] It is worth mentioning that the photovoltaic module installation method in the related art is to install the fixing parts on the metal tile, and then install the long rail bracket on the fixing parts, and use the rail bracket to fix and install the photovoltaic module; however, the rail bracket is a long profile, so it is not easy to bend, and it is difficult to install on the tile roof with a curved surface, and it is large in size and not conducive to transportation. In the present application, the photovoltaic module 4 is fixed and installed by the fixing parts 20 and the clamping parts 30. The fixing parts 20 and the clamping parts 30 are small in size, easy to carry, and the cost is lower than that of the rail bracket, which is conducive to reducing costs. In addition, the clamping device 1 is installed on the metal tile 2 at intervals, so that multiple positions of the photovoltaic module 4 can be dispersedly clamped, which is conducive to installing the photovoltaic module 4 on a curved roof.

[0036] In some embodiments, reference Figure 3 , Figure 4 and Figure 6 , the fixing member 20 is installed at the trough position 81 of the metal tile 2. Under the condition that the fixing member 20 supports the photovoltaic module 4, the support height of the bearing surface 211 of the fixing member 20 is consistent with the support height of the tile rib 82 of the metal tile 2. In other words, after the photovoltaic module 4 is installed in the clamping device 1, the contact surface of the bearing surface 211 and the photovoltaic module 4 is coplanar with the contact surface of the tile rib 82 of the metal tile 2 and the photovoltaic module 4, so as to avoid the height difference between different parts of the photovoltaic module 4 after installation, thereby helping to reduce the risk of stress concentration in the photovoltaic module 4. It can be understood that when the fixing member 20 is installed at the trough position 81 of the metal tile 2, the fixing member 20 is easy to connect with the purlin 3 under the metal tile 2, so as to improve the reliability of the installation of the fixing member 20, and further fix the metal tile 2 and the purlin 3.

[0037] In some embodiments, the clamping member 30 includes a clamping member 31 and a positioning member 32. The clamping member 31 is detachably connected to the fixing member 20 via a fastener 40. One end of the clamping member 31 is suitable for abutting against the fixing member 20. The other end of the clamping member 31 is detachably connected to the positioning member 32 to form a clamping area 10 between the positioning member 32 and the fixing member 20.

[0038] That is to say, referring to Figure 1 and Figure 2 The clamping member 31 is suitable for connecting the positioning member 32 and the fixing member 20 to form a clamping area 10 to position the photovoltaic module 4 in the height direction; the positioning member 32 is suitable for fitting with the surface of the photovoltaic module 4 to further position the photovoltaic module 4 in the horizontal direction. In addition, by replacing different positioning members 32, clamping areas 10 with different heights can be formed so that the pressing member 30 can be adapted to photovoltaic modules 4 of different thicknesses. In addition, by disassembling the clamping member 31 and the positioning member 32, the clamping member 31 or the positioning member 32 can be repaired or replaced respectively, which is conducive to reducing maintenance costs.

[0039] In some embodiments, reference Figure 2 , Figure 3 and Figure 6 The clamping member 31 has a through hole 3111; the fixing member 20 has a roughly long strip-shaped connecting structure 22, and the fastener 40 is suitable for passing through the through hole 3111 and the connecting structure 22 to connect the clamping member 31 and the fixing member 20, and the fastener 40 is suitable for moving along the extension direction of the connecting structure 22 to adjust the relative position of the clamping member 31 and the fixing member 20, thereby adjusting the position of the positioning member 32 connected to the clamping member 31, so that the distance between the two positioning members 32 located on the opposite sides of the same photovoltaic component 4 is adapted to the span of the photovoltaic component 4, reducing the risk of the photovoltaic component 4 being squeezed by the positioning member 32 and generating stress. Further, the difficulty of installing the photovoltaic component 4 on the clamping device 1 is reduced, which is conducive to improving the installation efficiency.

[0040] It is worth mentioning that a fixing member 20 can be connected to two clamping members 30 through a connecting structure 22, and the opening directions of the clamping areas 10 of the two clamping members 30 are opposite, so that the adjacent two side edges of two adjacent photovoltaic components 4 can be clamped by the two clamping members 30 on a fixing member 20, so that the number of fixing members 20 can be reduced, which is beneficial to reducing costs, and at the same time, it is beneficial to reduce the distance between two adjacent photovoltaic components 4, so that the arrangement of the photovoltaic components 4 is more compact.

[0041] Specifically, refer to Figure 2 The clamping member 31 includes a first transverse section 311, a first connecting section 312 and a second connecting section 314; a through hole 3111 is provided on the first transverse section 311 to be connected to the fixing member 20 through the fastener 40, the first connecting section 312 extends from one end of the first transverse section 311 to the fixing member 20 along the vertical direction, and the second connecting section 314 extends from the other end of the first transverse section 311 to the fixing member 20 along the vertical direction. The end of the second connecting section 314 is detachably connected to the positioning member 32. When the end of the first connecting section 312 abuts against the fixing member 20, a clamping area 10 is formed between the positioning member 32 and the bearing surface 211 of the fixing member 20.

[0042] Furthermore, the clamping member 31 also includes a first extension section 313, which extends laterally from the end of the first connecting section 312 away from the first transverse section 311, thereby increasing the contact area between the clamping member 31 and the fixing member 20, which is beneficial to improving the connection reliability between the clamping member 31 and the fixing member 20.

[0043] Furthermore, the clamping member 31 further includes a second extension section 315, which extends laterally from the end of the second connecting section 314 away from the first transverse section 311, thereby increasing the contact surface between the clamping member 31 and the positioning member 32. In addition, the second extension section 315 has a clamping groove 3151 on one side facing the positioning member 32, and the clamping groove 3151 extends from one end of the second extension section 315 toward one end of the first connecting section 312 (refer to Figure 2 The extending length of the snap-in groove 3151 is greater than the diameter of the groove so that the positioning member 32 is snap-fitted into the snap-in groove 3151; the positioning member 32 includes a fitting portion 321 suitable for fitting with the photovoltaic component 4, a clamping area 10 is formed between the fitting portion 321 and the fixing member 20, and a snap-in portion 322 is protrudingly provided on one side of the fitting portion 321 toward the second extension section 315, the snap-in portion 322 is suitable for being accommodated in the snap-in groove 3151 so that the positioning member 32 is connected to the clamping member 31, and the snap-in portion 322 is suitable for moving along the extending direction of the snap-in groove 3151.

[0044] Specifically, refer to Figure 2 The fitting portion 321 is in an "L" shape, including a main fitting section 3211 and a secondary fitting section 3212. The secondary fitting section 3212 is connected to one side of the main fitting section 3211 close to the first connecting section 312 of the clamping member 31. The lower surface of the main fitting section 3211 is suitable for fitting with the upper surface of the photovoltaic component 4. The upper surface of the main fitting section 3211 is protrudingly provided with a clamping portion 322 to be connected to the clamping member 31 through a clamping groove 3151. The secondary fitting section 3212 is suitable for fitting with the side of the photovoltaic component 4 to position the photovoltaic component 4 in the horizontal direction.

[0045] In a specific embodiment, referring to Figure 1 and Figure 2 The engaging groove 3151 extends along the length direction of the clamping member 31 (refer to Figure 2 The second extension section 315 is provided with a plurality of second extension sections 315 extending along the length of the second extension section 315, so that the clamping portion 322 of the positioning member 32 is adapted to enter the clamping groove 3151 from any end of the clamping member 31, thereby making the installation easier. Figure 2The clamping member 31 and the positioning member 32 are extended in a direction perpendicular to the paper surface, and the length of the clamping portion 322 is consistent with the length of the positioning member 32, which is conducive to making the clamping member 31 and the positioning member 32 both in the form of profiles, thereby reducing the manufacturing cost. In other words, the cross-sections of the clamping member 31 and the positioning member 32 along their length directions are consistent everywhere, so that they can be manufactured in the form of profiles, and then the clamping member 31 and the positioning member 32 can be obtained by cutting the profile of the required length, and the through hole 3111 can be set on the first transverse section 311 by drilling, which is conducive to simplifying the manufacturing process of the clamping member 31 and the positioning member 32, so that the manufacturing of the clamping member 31 and the positioning member 32 is convenient.

[0046] Furthermore, in an optional embodiment, the material of the clamping member 31 and the positioning member 32 is aluminum alloy, so as to reduce the weight of the clamping member 31 and the positioning member 32 , which is beneficial to reducing the load of the metal tile 2 .

[0047] In some embodiments, reference Figure 1 and Figure 3 The clamping device 1 also includes a connector 50; the fixing member 20 includes a first transverse fixing section 21, a second fixing section 23 and a supporting section 24. The first fixing section 21 is provided with a bearing surface 211 to support the photovoltaic module 4. The first fixing section 21 is also provided with a connecting structure 22 to connect with the clamping member 31. The first fixing section 21 is connected to a supporting section 24 at each of the opposite ends. The supporting section 24 extends in a direction away from the clamping member 31 to support the first fixing section 21, so that the supporting height of the bearing surface 211 is consistent with the supporting height of the tile rib 82 of the metal tile 2. The end of the supporting section 24 is connected to the second fixing section 23, and the second fixing section 23 is connected to the metal tile 2 through the connector 50, so that the fixing member 20 is installed at the trough position 81 of the metal tile 2.

[0048] In a specific embodiment, the connecting member 50 is a self-tapping screw, so as to facilitate the installation of the fixing member 20 on the purlin 3, which is beneficial to improve the installation efficiency.

[0049] Further, see Figure 1 The supporting section 24 of the fixing member 20 is connected to the opposite sides of the first fixing section 21 along the width direction, that is, the supporting section 24 extends along the length direction of the fixing member 20 to improve the bearing capacity of the supporting section 24, which is beneficial to improving the structural strength of the fixing member 20.

[0050] Further, refer to Figure 1 The connecting structure 22 extends along the length direction of the positioning member 32, which is beneficial to reducing the size of the fixing portion and is beneficial to making the fixing portion in the form of a profile.

[0051] It is worth mentioning that, referring to Figure 1When the clamp 31 is installed on the fixing member 20, the length direction of the clamp 31 is perpendicular to the length direction of the fixing member 20, so that the position of the positioning member 32 can be adjusted in two perpendicular directions. Specifically, the positioning member 32 and the clamp 31 are connected by the clamping portion 322 and the clamping groove 3151, and the clamping groove 3151 extends along the length direction of the clamp 31, so that the positioning member 32 can move along the length direction of the clamp 31; the clamp 31 and the fixing member 20 are connected by the fastener 40, and the connecting structure 22 extends along the length direction of the fixing member 20, so that the clamp 31 can move along the length direction of the fixing member 20; and then when the length direction of the clamp 31 is perpendicular to the length direction of the fixing member 20, the positioning member 32 can move along the length direction of the clamp 31 and the length direction of the fixing member 20, so that the position adjustment range of the positioning member 32 can be increased, which is conducive to reducing the installation difficulty of the photovoltaic module 4.

[0052] It is worth mentioning that, in some optional embodiments, referring to Figure 1 The length of the positioning member 32 is greater than the length of the clamping member 31, so that the contact area between the positioning member 32 and the photovoltaic component 4 is increased, thereby improving the connection reliability; the length of the clamping member 31 is less than the width of the fixing member 20, so that the fixing member 20 can stably support the clamping member 31.

[0053] In a specific embodiment, referring to Figure 1 and Figure 4 , the fixing member 20 is in a "J" shape. That is, the two opposite ends of the first fixing section 21 are each connected to a supporting section 24, and the supporting section 24 extends in a direction away from the clamping member 31 to support the first fixing section 21; the end of each supporting section 24 is respectively connected to a second fixing section 23, and the second fixing section 23 extends laterally away from the first fixing section 21 and is connected to the metal tile 2 through the connecting member 50.

[0054] Further, see Figures 3 to 5 , the fastener 40 is a bolt, and the connecting structure 22 is a through hole 221 and a long hole 222. Specifically, a through hole 3111 is provided on the first transverse section 311 of the clamping member 31, suitable for the rod of the bolt to pass through; a through hole 221 and a long hole 222 connected to the through hole 221 are provided on the first fixing section 21 of the fixing member 20, the through hole 221 is suitable for the head of the bolt to pass through, and the long hole 222 is suitable for the rod of the bolt to pass through, and the bolt can move along the extension direction of the long hole 222 to adjust the relative position of the clamping member 30 and the fixing member 20. Specifically, the through hole 221 is provided in the middle area of ​​the first fixing section 21, and the long hole 222 extends along the length direction of the fixing member 20. So as to facilitate the installation of a clamping member 30 at each end of the fixing member 20.

[0055] In another specific embodiment, referring to Figure 6, the fixing member 20 is in a "mouth" shape. That is, the two opposite ends of the first fixing section 21 are each connected to a supporting section 24, and the supporting section 24 extends in a direction away from the clamping member 31 to support the first fixing section 21; the second fixing section 23 is disposed below the first fixing section 21 and connected to the metal tile 2 through the connecting member 50, and the ends of the two supporting sections 24 are respectively connected to one end of the second fixing section 23.

[0056] Furthermore, the fastener 40 is a bolt, and the connecting structure 22 is a connecting groove 223 provided on the fixing member 20. Specifically, a through hole 3111 is provided on the first transverse section 311 of the clamping member 31, suitable for the rod of the bolt to pass through; a connecting groove 223 is provided on the first fixing section 21 of the fixing member 20, suitable for accommodating the head of the bolt, so that the bolt can move along the extending direction of the connecting groove 223 to adjust the relative position of the pressing member 30 and the fixing member 20. It is worth mentioning that a supporting structure can also be provided between the connecting groove 223 and the second fixing section 23 to enhance the structural strength of the fixing member 20.

[0057] Specifically, the cross section of the connecting groove 223 can be "convex" to form an opening located at the first fixing section 21, suitable for the rod of the screw to pass through. It can be understood that the connecting groove 223 is formed along the length direction of the fixing member 20 (refer to Figure 6 The connecting groove 223 is formed in a "mouth" shape and is located below the first fixing section 21. The connecting groove 223 is connected to the through hole 221 and the long hole 222 provided in the first fixing section 21, so that the head of the screw can enter the connecting groove 223 from any end of the fixing section 20 and move along the extending direction of the connecting groove 223.
