Description

Technical Field

[0001] This utility model relates to the field of photovoltaic equipment technology, and in particular to a hook device and a photovoltaic module installation structure. Background Technology

[0002] In the residential photovoltaic (PV) sector, mounting devices are typically used to install PV modules on rooftops. A traditional type of roofing tile is the curved tile, such as the small black tile, which is usually made of clay. In the application of small black tiles, they are laid in layers to cover the roof.

[0003] A traditional hook has a fixed height. When used on roofs with curved tiles, the hook may not fit the tile well because the tile has an uneven, curved structure. This can cause the hook to crush the tile or the tile to be excessively lifted by the hook, making the roof prone to leaks.

[0004] Therefore, how to reduce the impact of hooks on roofs with curved tiles is a technical problem that needs to be solved by those skilled in the art. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide a hook device and a photovoltaic module installation structure including the above-mentioned hook device. When this hook device is used, the impact on the roof with curved tiles can be reduced.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A hook device includes a base and an intermediate support member. The intermediate support member includes a support arm and two connecting arms, which are respectively fixed to both ends of the support arm. The two connecting arms can be switched as a first connecting arm and a second connecting arm. The first connecting arm is fixedly connected to the base and has a downward-folding structure relative to the support arm, while the second connecting arm has an upward-folding structure relative to the support arm. When the two connecting arms are respectively used as the first connecting arms and fixedly connected to the base, the height difference between the first intersection point formed between the support arm and the first connecting arm and the bottom surface of the base is different.

[0008] Preferably, a second intersection point is formed between the support arm and the second connecting arm, and the support arm gradually tilts downward along the direction from the first intersection point toward the second intersection point.

[0009] Preferably, the intermediate support member has a Z-shaped structure, and the two connecting arms are arranged in parallel with different lengths.

[0010] Preferably, the two connecting arms are integrally formed with the support arm.

[0011] Preferably, reinforcing ribs are provided between the two connecting arms and the support arm.

[0012] Preferably, it further includes an upper support component; the upper support component includes a first upright plate and a first horizontal plate fixed to the top of the first upright plate, the second connecting arm is fixedly connected to the first upright plate, and the first horizontal plate is located above the second connecting arm.

[0013] Preferably, the two connecting arms are respectively provided with arm connecting holes, and the first upright plate is provided with upper support component connecting holes; the arm connecting holes of the second connecting arm are bolted to the upper support component connecting holes by a second fastener, and the upper support component connecting holes have multiple positions in the height direction for the second fastener to be installed.

[0014] Preferably, the base includes a second upright plate and a second horizontal plate fixed to one side of the bottom of the second upright plate, and the first connecting arm is fixedly connected to the second upright plate; the first connecting arm and the second horizontal plate are located on the same side of the second upright plate, and the bottom end of the first connecting arm is located above the second horizontal plate; or, the first connecting arm and the second horizontal plate are located on opposite sides of the second upright plate.

[0015] Preferably, arm connection holes are provided on the two connecting arms, and base connection holes are provided on the base; the arm connection hole of the first connecting arm is fastened to the base connection hole by a first fastener, and the base connection hole has multiple positions in the height direction for the first fastener to be installed.

[0016] A photovoltaic module mounting structure includes a hook device as described above, and a roof structure layer, a first layer of curved tiles, and a second layer of curved tiles arranged sequentially from bottom to top. The base is fixed downward to the roof structure layer between two adjacent first layer curved tiles, and the support arm is located above one of the first layer curved tiles. The second layer curved tiles are concave-facing and fastened above two adjacent first layer curved tiles, with one end resting above the support arm. The top of the hook device is higher than the second layer curved tiles to support the photovoltaic module.

[0017] The hook device provided by this utility model includes a base and an intermediate support. The intermediate support includes a support arm and two connecting arms, which are respectively fixed to both ends of the support arm. The two connecting arms can be switched as a first connecting arm and a second connecting arm. The first connecting arm is fixedly connected to the base, and the first connecting arm is a downward-folding structure relative to the support arm, while the second connecting arm is an upward-folding structure relative to the support arm. When the two connecting arms are respectively used as the first connecting arm and fixedly connected to the base, the height difference between the first intersection point formed between the support arm and the first connecting arm and the bottom surface of the base is different.

[0018] Because the two connecting arms can switch to act as the first connecting arm, the distance between the first intersection point of the support arm and the bottom surface of the base in the height direction can be changed, so that the hook device can have different shapes after assembly. It can adjust the height of at least part of the structure of the support arm relative to the mounting surface on the bottom surface of the base. Moreover, this adjustment does not require adding or removing parts, and can be adapted to curved tiles of different heights. It solves the problem of excessive squeezing and breaking of curved tiles, reduces roof leakage, and effectively reduces the impact on the roof with curved tiles. Attached Figure Description

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] The core of this utility model is to provide a hook device and a photovoltaic module installation structure including the hook device. When this hook device is used, the impact on the roof with curved tiles can be reduced.

[0040] For a specific embodiment of the hook device provided by this utility model, please refer to Embodiment 1. Figures 1 to 5 It includes: base 1 and intermediate support 2.

[0041] like Figure 2 As shown, the intermediate support 2 includes a support arm 23 and two connecting arms 24. The two connecting arms 24 are fixed to both ends of the support arm 23 and are respectively located on both sides of the support arm 23. Specifically, the two connecting arms 24 extend on both sides of two opposite surfaces of the support arm 23, and the support arm 23 and the two connecting arms 24 have an angle of less than 180°.

[0042] The two connecting arms 24 can be switched to serve as the first connecting arm 21 and the second connecting arm 22. The first connecting arm 21 is the structure in the intermediate support member 2 that is fixedly connected to the base 1, and the upper part of the second connecting arm 22 is used to support the photovoltaic module. Figure 3 and Figure 5As shown, the base 1 is used to fix the roof structure layer 7. The first connecting arm 21 is fixedly connected to the base 1. The first connecting arm 21 is a downward structure relative to the support arm 23, and the second connecting arm 22 is an upward structure relative to the support arm 23. Here, upward and downward refer to the positional relationship between the connecting arm 24 and the support arm 23. The processing method is not limited. The processing method can be to bend and folded into shape, or it can be fixed and connected by welding or other methods to form a flip-type shape structure.

[0043] It should be noted that, in order to make the structure clear, the description of the embodiments in this application is based on a preset height direction. The positive and negative directions in the height direction are the up and down directions, respectively, and should not be construed as limiting this application.

[0044] When the two connecting arms 24 are respectively used as the first connecting arms 21 and fixedly connected to the base 1, the height difference between the first intersection point a formed between the support arm 23 and the first connecting arm 21 and the bottom surface of the base 1 is different, such as... Figure 5 and Figure 8 The two cases shown, Figure 5 The height difference is less than Figure 8 The height difference. Additionally, the second intersection point b formed between the support arm 23 and the second connecting arm 22.

[0045] It should be noted that the switching operation between the two connecting arms 24 is performed before the hook device is assembled. After the hook device is assembled, it is determined whether it can be switched again based on the assembly method between the base 1 and the intermediate support 2. For example, if the base 1 and the intermediate support 2 are connected by bolts or other detachable methods, the two connecting arms 24 can be switched again. If the base 1 and the intermediate support 2 are connected by welding or other non-detachable methods, the switching operation cannot be performed.

[0046] Specifically, before the hook device itself is assembled, mainly before the separate base 1 and intermediate support 2 are connected as one unit, one of the two connecting arms 24 is selected as the first connecting arm 21 according to the height of the arc-shaped tile 6. This makes the distance between the first intersection point a of the support arm 23 and the bottom surface of the base 1 in the height direction larger when the height of the arc-shaped tile 6 is large, and the distance between the first intersection point a of the support arm 23 and the bottom surface of the base 1 in the height direction smaller when the height of the arc-shaped tile 6 is small.

[0047] When applied to a roof covered with two layers of curved tiles (e.g., small black tiles), such as Figure 5As shown, the base 1 is fixed to the roof structure layer 7 and located between adjacent lower curved tiles 6. The base 1 is fixedly connected to the first connecting arm 21, which is located below the first intersection point a of the support arm 23. With the support of the base 1, one of the support arms 23 is suspended above the lower curved tile 6, specifically with a certain gap from the lower curved tile 6. The second intersection point b can be located in the middle of the lower curved tile 6, which can reduce the risk of the intermediate support 2 excessively pressing down on the lower curved tile 6. The upper curved tile 6 has its concave surface facing down and one end overlaps the support arm 23. The second connecting arm 22 is located above the second intersection point b of the support arm 23 and is used to support the photovoltaic module.

[0048] Because the two connecting arms 24 can switch to function as the first connecting arm 21, thereby changing the height distance between the first intersection point a of the support arm 23 and the bottom surface of the base 1, the hook device can be assembled into different shapes. This allows adjustment of the height of at least a portion of the support arm 23 relative to the mounting surface of the base 1, without the need for adding or removing parts. It can accommodate curved tiles 6 of different heights, solving the problem of excessive pressure causing tile breakage, reducing roof leaks, and effectively minimizing the impact on the roof where the curved tiles 6 are laid. Of course, depending on actual needs, the tiles can also be of other shapes besides the curved tile 6.

[0049] Furthermore, to improve the fit between the hook device and the curved tile 6, such as... Figure 3 As shown, the support arm 23 gradually tilts downwards along the direction from the first intersection point a towards the second intersection point b. On the roof, as... Figure 5 As shown, the concave surface of the lower layer of curved tile 6 is on top, and the first intersection point a of the support arm 23 is higher than the second intersection point b. The first intersection point a is located at the edge of the lower layer of curved tile 6, and the second intersection point b is located at the middle of the lower layer of curved tile 6, which matches the tilt direction of the concave surface of the lower layer of curved tile 6. The fit between the support arm 23 and the lower layer of curved tile 6 is good. The concave surface of the upper layer of curved tile 6 is on the bottom, and the first intersection point a of the support arm 23 supports the higher middle part of the concave surface of the upper layer of curved tile 6, while the second intersection point b supports the lower edge of the concave surface of the upper layer of curved tile 6. The fit between the support arm 23 and the upper layer of curved tile 6 is also good. This can improve the fit between the support arm 23 and the upper layer of curved tile 6, so as to ensure the fit and coverage between different layers of tiles and further reduce the risk of roof leakage.

[0050] Furthermore, the intermediate support 2 has a Z-shaped structure. It should be noted that the Z-shaped structure of the intermediate support 2 mainly refers to the overall structure formed by the two connecting arms 24 flipping in the opposite direction relative to the support arm 23. It does not restrict the individual structural design of the connecting arms 24 and the support arm 23. For example, the connecting arms 24 and the support arm 23 can be set as flat plate structures, or as curved plates, corrugated plates, etc.

[0051] At this time, as Figure 2 As shown, the intermediate support 2 only includes a support arm 23 and two connecting arms 24 that are flipped in the opposite direction to the support arm 23, without any other arms, which simplifies the structure while meeting functional requirements. Of course, in other embodiments, the intermediate support 2 may also include other arms, for example, another arm that docks to the first intersection point a or the second intersection point b, or the intermediate support 2 may be H-shaped as a whole. In addition, when switching the two connecting arms 24 as the first connecting arm 21, this can be achieved by flipping the intermediate support 2; for example, when the two connecting arms 24 are parallel, the intermediate support 2 is flipped 180° as a whole.

[0052] For example, such as Figure 2 As shown, the two connecting arms 24 are arranged in parallel and have different lengths, namely the shorter first arm 241 and the longer second arm 242. Here, the length refers to the distance between the free end of the connecting arm 24 and the intersection point of the connecting arm 24 and the support arm 23. When the two connecting arms 24 serve as the first connecting arms 21, the height difference between the first intersection point a and the base 1 can be easily achieved. Of course, in this embodiment, the two connecting arms 24 can also have an included angle greater than 0.

[0053] For example, such as Figure 2 As shown, both connecting arms 24 and the support arm 23 form an acute angle to ensure that after assembly onto the roof, the support arm 23 is better adapted to the tilt direction of the curved tile 6, resulting in a first intersection point a being higher than the second intersection point b. Of course, in other embodiments, the connecting arms 24 and the support arm 23 can also be arranged vertically.

[0054] For example, the two connecting arms 24 and the support arm 23 are integrally formed. For instance, the intermediate support member 2 is a bent part formed by bending the same plate, or the two connecting arms 24 and the support arm 23 are directly cast into a single structure. This integral forming process can improve structural strength. Of course, in other embodiments, the connecting arms 24 and the support arm 23 can also be fixed into a single structure by welding or bolting different plates.

[0055] For example, such as Figure 4 As shown, reinforcing ribs 25 are respectively provided between the two connecting arms 24 and the support arm 23 to further improve the deformation resistance of the intermediate support 2. In some embodiments, during processing, the two bends between the support arm 23 and the two connecting arms 24 are rounded corner structures, and both are formed by stamping an arc-shaped outer edge to create a bulge towards the center at the bend, forming stamped ribs 25 to enhance the bending and deformation resistance of the intermediate support 2 and reduce the pressure of the support arm 23 on the lower tile. Alternatively, the reinforcing ribs 25 can also be additionally welded to the triangular plate of the intermediate support 2.

[0056] Furthermore, such as Figure 1 As shown, the hook device also includes an upper support component 3 for directly connecting the photovoltaic module. Of course, in other embodiments, the photovoltaic module can also be directly connected using an intermediate support component 2.

[0057] Among them, such as Figure 1 As shown, the upper support component 3 includes a first vertical plate 31 and a first horizontal plate 32 fixed to the top of the first vertical plate 31. Specifically, the upper support component 3 can be an L-shaped structure, or a T-shaped structure in other embodiments. In some embodiments, the first vertical plate 31 and the first horizontal plate 32 are respectively flat plates arranged perpendicularly to each other. The second connecting arm 22 is fixedly connected to the first vertical plate 31, and the first horizontal plate 32 is located above the second connecting arm 22. Using the first horizontal plate 32 as a connection structure with the photovoltaic module increases the contact area and ensures the structural strength of the connection.

[0058] For example, such as Figure 1 and Figure 5 As shown, the first horizontal plate 32 is provided with component connection holes, specifically strip holes or round holes, and the number can be one or more. The component connection holes of the first horizontal plate 32 are used to fix the photovoltaic module to the third fastener 8, specifically fixed below the photovoltaic module connection part 9 in the photovoltaic module. In some embodiments, the third fastener 8 is a combination of hexagon socket head cap screws.

[0059] For example, such as Figure 1 As shown, each of the two connecting arms 24 is provided with an arm connecting hole 243. The arm connecting holes 243 are respectively bolted to the upper support component connecting hole 33 on the upper support component 3 and the base connecting hole 13 on the base 1. For example, a combination of carriage bolts can be used for bolting, which allows for flexible assembly and disassembly.

[0060] In some embodiments, the arm connection holes 243 on the connecting arm 24 are all set as square holes, for example, square holes or rectangular holes, which are adapted to the square neck shape of the carriage bolt head in the carriage bolt assembly, allowing for a relatively tight fit, and the carriage bolt assembly does not rotate after bolting. In other embodiments, the connecting arm 24 and the corresponding base 1 and upper support component 3 can also be fixedly connected by welding or other methods.

[0061] In some embodiments, the connecting arm 24 is provided with an arm connection hole 243. At least one arm connection hole 243 on the connecting arm 24 is a strip-shaped hole extending along the length direction of the connecting arm 24, so that the base 1 and the upper support member 3 can be bolted to different positions in the height direction of the strip-shaped hole, increasing the height adjustment range of the hook device. Of course, in other embodiments, multiple arm connection holes 243 can be provided on the connecting arm 24. In addition, the fastener used for bolting may have only one installation position in the arm connection hole 243 and cannot move in the arm connection hole 243.

[0062] For example, such as Figure 1and Figure 3 As shown, the first upright plate 31 is provided with an upper support component connection hole 33, and the arm connection hole 243 of the second connecting arm 22 is bolted to the upper support component connection hole 33 by the second fastener 5.

[0063] In some embodiments, such as Figure 1 As shown, the upper support component connection hole 33 has multiple positions for installing the second fastener 5 in the height direction, so that the height of the upper support component 3 relative to the intermediate support component 2 is adjustable. This allows for leveling of the photovoltaic module connection parts 9, such as the inclined beams of the photovoltaic modules, and better adapts to uneven roof structures. Of course, in other embodiments, the second fastener 5 may have only one installation position in the upper support component connection hole 33 and cannot move within the upper support component connection hole 33.

[0064] In some embodiments, such as Figure 1 As shown, the upper support component connecting hole 33 is a strip-shaped hole extending along the height direction. When the second fastener 5 is connected to the same position as the second connecting arm 22, the fixed connection height of the upper support component 3 relative to the intermediate support member 2 can be adjusted by moving the second fastener 5 up and down in the upper support component connecting hole 33. Alternatively, the upper support component connecting hole 33 can also be a round hole or a square hole, but the size of the second fastener 5 is smaller than the upper support component connecting hole 33 to achieve adjustable height position in the upper support component connecting hole 33.

[0065] In some embodiments, such as Figure 5 As shown, the side of the second connecting arm 22 is fitted to the side of the first upright plate 31. In addition, the bottom end of the second connecting arm 22 can be fitted to or spaced from the bottom surface of the first horizontal plate 32 to improve the stability of the connection between the intermediate support 2 and the base 1.

[0066] Furthermore, such as Figure 1 As shown, the base 1 includes a second vertical plate 11 and a second horizontal plate 12 fixed to one side of the bottom of the second vertical plate 11. At this time, the bottom surface of the second horizontal plate 12 is specifically the bottom surface of the base 1, which is used to contact the mounting surface of the hook device to be installed, such as the top surface of the roof structure layer 7, to ensure the contact area with the mounting surface and ensure the support capacity.

[0067] For example, the second upright plate 11 and the second horizontal plate 12 form an L-shaped structure, specifically with an included angle of 90°. In some embodiments, the second upright plate 11 can be centrally fixed to one side of the second horizontal plate 12 to improve the support capacity of the base 1. In addition, the second horizontal plate 12 is provided with one or more holes to connect to the second upright plate 11, specifically for bolting.

[0068] For example, such as Figure 3 and Figure 5As shown, the first connecting arm 21 and the second horizontal plate 12 are located on the same side of the second vertical plate 11, and the bottom end of the first connecting arm 21 is located above the second horizontal plate 12. Specifically, the bottom end of the first connecting arm 21 may have a height difference with or be in contact with the second horizontal plate 12; or, in other embodiments, such as Figure 6 and Figure 8 As shown, the first connecting arm 21 and the second horizontal plate 12 are located on both sides of the second vertical plate 11. The bottom end of the first connecting arm 21 can have a height difference with or be attached to the roof structure layer 7, so that the intermediate support 2 can be flexibly assembled on the base 1.

[0069] In some embodiments, such as Figure 5 As shown, the side of the first connecting arm 21 is fitted against the side of the second vertical plate 11. Additionally, the bottom end of the first connecting arm 21 can be fitted against the top surface of the second horizontal plate 12; or, as... Figure 8 As shown, the bottom end of the first connecting arm 21 can be fitted to the top surface of the roof structure layer 7, thereby improving the stability of the connection between the intermediate support 2 and the base 1.

[0070] In some embodiments, such as Figure 1 and Figure 3 As shown, a base connection hole 13 is provided on the base 1, specifically opened on the second upright plate 11. The arm connection hole 243 of the first connecting arm 21 is bolted to the base connection hole 13 by the first fastener 4, and the base connection hole 13 has multiple positions for the first fastener 4 to be installed in the height direction, so that the height of the intermediate support 2 relative to the base 1 is adjustable, which can further increase the range of relative height between the intermediate support 2 and the base 1, and further adapt to the height of the tile, mainly adapting to the height of the tile below the support arm 23.

[0071] In some embodiments, such as Figure 1 As shown, the base connection hole 13 is a strip-shaped hole extending along the height direction. When the first fastener 4 is connected to the same position as the first connecting arm 21, the fixed height of the intermediate support 2 relative to the base 1 can be adjusted by moving the first fastener 4 up and down in the base connection hole 13. Alternatively, the base connection hole 13 can also be a round hole or a square hole, but the size of the first fastener 4 is smaller than the base connection hole 13 to achieve adjustable height position in the base connection hole 13. Of course, in other embodiments, the first fastener 4 may only have one installation position in the base connection hole 13 and cannot move in the base connection hole 13.

[0072] In some embodiments, for two connecting arms 24, when the shorter first arm body 241 is used as the first connecting arm 21, such as Figure 4As shown, the first connecting arm 21 and the second horizontal plate 12 are located on the same side of the second vertical plate 11; when the intermediate support 2 is flipped, with the longer second arm 242 serving as the first connecting arm 21, as... Figure 8 As shown, the first connecting arm 21 and the second horizontal plate 12 are located on both sides of the second vertical plate 11. Meanwhile, compared with the previous case, the first fastener 4 is flipped to face the assembly.

[0073] The hook device in this embodiment is used for the installation of photovoltaic modules on the roof. During the installation process, based on the structure of the curved tile 6, one of the two connecting arms 24, the first arm 241 and the second arm 242, is selected as the first connecting arm 21 to serve as the connection structure with the base 1, and the other is selected as the second connecting arm 22.

[0074] (a) such as Figures 3 to 5 As shown, the curved tile 6 is a first type of curved tile 61 with a smaller height and shallower concave depth. In this case, the first arm 241 with a shorter length is used as the first connecting arm 21 to adapt to the height of the first type of curved tile 61. The hook device formed by connecting the first connecting arm 21, the base 1, and the upper support component 3 is the first type of hook. The first type of hook is suitable for houses with smaller tiles. When used to connect photovoltaic modules, the upper support component 3 is fixed to the lower part of the photovoltaic module connection 9 (e.g., the inclined beam of the photovoltaic module) by the third fastener 8. The base 1 is fixed to the roof structure layer 7 through the space between the lower first type of curved tiles 61. At this time, since the first arm 241 with a shorter length is selected as the first connecting arm 21, the height of the first connecting arm 21 is smaller, and the fit with the shallow first type of curved tile 61 is better.

[0075] (ii) such as Figures 6 to 8 As shown, the curved tile 6 is a second type of curved tile 62 with a larger height and a larger concave depth. In this case, the longer second arm 242 is used as the first connecting arm 21 to adapt to the height of the second type of curved tile 62. The hook device formed by connecting the first connecting arm 21, the base 1, and the upper support component 3 is the second type of hook. The second type of hook is suitable for house types with larger tiles. In the process of connecting photovoltaic modules, the upper support component 3 is fixedly connected to the photovoltaic module connection part 9 (e.g., the inclined beam of the photovoltaic module) through the third fastener 8. The base 1 is fixed to the roof structure layer 7 through the space between the lower layer of second type of curved tiles 62. At this time, because the longer second arm 242 is selected as the first connecting arm 21, the height of the first connecting arm 21 is larger, and the fit with the deeper second type of curved tile 62 is better.

[0076] The hook device in this embodiment has the following advantages: the intermediate support 2 can be fixed to the base 1 in different installation positions, allowing the hook device to accommodate at least two different tile heights; the intermediate support 2 and the upper support component 3 can be fixed at different heights, and the intermediate support 2 and the base 1 can be fixed at different heights, enabling further fine-tuning of the height of the intermediate support 2 or the upper support component 3, which can further adapt to the height of the tiles and photovoltaic modules; the intermediate support 2 has reinforcing ribs 25, which have good resistance to deformation, thereby reducing the possibility of roof leakage from different angles.

[0077] In addition to the hook device described above, this utility model also provides a photovoltaic module installation structure, which includes a hook device.
