Description

Technical Field

[0001] This utility model relates to the field of photovoltaic bracket technology, and in particular to a height-adjustable photovoltaic bracket hook. Background Technology

[0002] Photovoltaic power generation is one of the most widely used methods for producing clean electricity, and photovoltaic brackets are an important component in the construction of photovoltaic power plants.

[0003] Currently, there are few types of hooks suitable for rooftop fixed photovoltaic brackets. Usually, the hook structure is an integrated fixed type, and most of the hooks are suitable for ordinary large tile roofs. However, there is little research on fixed hooks suitable for small terracotta tile roofs. Small terracotta tiles themselves have low strength. If they are subjected to force on the tile surface when bearing weight, like ordinary hooks, it is easy to cause the tile to break. In particular, there are very few types of hooks that can adjust the support height.

[0004] Therefore, it is necessary to research a hook that can be used on small terracotta tile roofs, protect the tiles, be flexible and convenient to install, and have an adjustable height. Utility Model Content

[0005] The purpose of this utility model is to provide a height-adjustable photovoltaic bracket hook to solve the problems existing in the prior art. It can be used on small terracotta tile roofs, reduce the breakage of the tiles, and is flexible and convenient to install with adjustable height.

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

[0007] This utility model provides a height-adjustable photovoltaic bracket hook, including a fixed base, a central connecting plate, and a supporting bending plate arranged vertically from bottom to top. The fixed base includes a base plate, a clearance plate, and a first connecting plate fixedly connected vertically from bottom to top. The base plate is used to fix to a wooden beam, rafter, or sheath at the bottom of a tiled roof. The clearance plate is used to be installed in the installation gap of the tiled roof, with its lower end fixedly connected to the base plate and its upper end fixedly connected to the lower end of the first connecting plate. The first connecting plate is located above the tiled roof and has a first elongated hole. The central connecting plate has a U-shaped groove. The U-shaped groove contains... One end is provided with a first connecting hole, and the other end of the U-shaped groove is provided with a second connecting hole; the lower end of the supporting bending plate has a second connecting plate; the second connecting plate has a second elongated hole; the upper end of the first connecting plate and the lower end of the second connecting plate are both slidably disposed in the U-shaped groove in the vertical direction; the first elongated hole of the first connecting plate corresponds to the first connecting hole of the middle connecting plate; the second elongated hole of the second connecting plate corresponds to the second connecting hole of the middle connecting plate; connecting bolts are inserted into the first elongated hole and the first connecting hole, and into the second elongated hole and the second connecting hole, and the threaded end of the connecting bolt is threadedly connected to a connecting nut.

[0008] Preferably, both the first connecting hole and the second connecting hole are oblong holes.

[0009] Preferably, the supporting bending plate further includes a horizontal mounting plate, one end of which is fixedly connected to the upper end of the second connecting plate; the horizontal mounting plate is provided with mounting holes.

[0010] Preferably, the first connecting plate, the second connecting plate, and the middle connecting plate are all U-shaped plates.

[0011] Preferably, the second connecting plate is further provided with a third elongated hole, which is located on the side of the second elongated hole near the middle connecting plate; and the extension direction of the third elongated hole is the same as the extension direction of the second elongated hole; the third elongated hole can correspond to the second connecting hole of the middle connecting plate.

[0012] Preferably, the base plate has at least two fixed elongated holes, and a clamp can be inserted into the fixed elongated holes.

[0013] Preferably, the base plate is also provided with a plurality of small round holes, and self-tapping screws can be inserted into the small round holes.

[0014] Preferably, the mounting hole is an oblong hole.

[0015] Preferably, the clearance plate includes a vertical plate and a horizontal plate; the lower end of the vertical plate is fixedly connected to the base plate, and the horizontal plate and the base plate are both located on the same side of the vertical plate; one end of the horizontal plate is fixedly connected to the upper end of the vertical plate; and the other end of the horizontal plate is fixedly connected to the lower end of the first connecting plate.

[0016] Preferably, the connecting bolt is a high-strength bolt.

[0017] The present invention achieves the following technical advantages over the prior art:

[0018] This utility model provides a height-adjustable photovoltaic bracket hook, which is fixed to the wooden beams, rafters, or shingles at the bottom of the tiled roof via a base plate. This directly transfers the force of the entire hook to the roof's supporting structure, rather than the tiles bearing the load. By placing the clearance plate in the gap, excessive local pressure caused by direct contact between the hook and the tiles is avoided, thus reducing the possibility of tile breakage. The upper end of the first connecting plate and the lower end of the second connecting plate are both slidably positioned vertically within the U-shaped groove of the middle connecting plate. This sliding connection method allows for flexible adjustment of the relative positions of the various components during installation, according to actual needs. For example, if the hook height needs to be finely adjusted on-site, simply slide the first and second connecting plates along the U-shaped groove; there is no need to disassemble or make complex adjustments to the entire hook. The elongated hole provides a certain displacement space for the bolts, ensuring the reliability of the connection while adjusting the height. After the height is adjusted, the connecting bolts and nuts can tightly fix the various components together, ensuring the stability of the hook during use.

[0019] Furthermore, the first connecting hole and the second connecting hole adopt an elongated oval hole structure, which, together with the structure of the first elongated oval hole and the second elongated oval hole, can achieve a larger height adjustment range.

[0020] Furthermore, the presence of the horizontal mounting plate provides a stable mounting surface for the photovoltaic (PV) system. During installation, installers can place the connecting parts of the system directly on the horizontal mounting plate and secure them through the mounting holes.

[0021] Furthermore, the U-shaped plate structure has excellent bending resistance when subjected to external forces. When the photovoltaic support is subjected to external forces such as wind load or snow load, the two side plates of the U-shaped plate can effectively resist bending moment, greatly enhancing the deformation resistance and load-bearing capacity of the hook, and ensuring the overall stability of the hook.

[0022] Furthermore, the third elongated hole works in conjunction with the second elongated hole. Compared to the case with only a single elongated hole, the double elongated hole design can better distribute external forces, reduce component damage caused by excessive local stress, and thus extend the service life of the hook.

[0023] Furthermore, the base plate has a fixed elongated hole that can be used to insert clamps, providing a flexible and diverse way to fix the hooks. On small terracotta tile roofs, different roof structures may have different requirements for fixing methods. The clamps can be adjusted according to the shape and size of the roof beams, rafters, or sheathings, and can better adapt to various irregular support structures. On the actual installation site, construction workers can quickly adjust the position and tightness of the clamps according to the actual situation of the roof. This on-site adjustability greatly improves installation efficiency.

[0024] Furthermore, the small round holes allow for the insertion of self-tapping screws. This design, combined with the clamp fixing method, provides a more stable installation effect. The clamps are mainly used to hold the wooden beams, rafters, or roof boards at the bottom of the roof, while the self-tapping screws can further fix the base plate to these supporting structures. This dual fixing method makes the installation of the hooks on the small terracotta tile roof more secure and reliable. Multiple self-tapping screws are fixed to the roof supporting structure through the small round holes, which can distribute the force borne by the hooks to multiple points. This avoids the force being concentrated on a few fixing points, reducing the risk of excessive local pressure causing damage to the roof structure or loosening of the hooks.

[0025] Furthermore, various complex situations may arise at the actual installation site. The design of the elongated hole facilitates fine-tuning during the installation process. If it is found that the initial installation position of the photovoltaic bracket and the hook is not perfectly matched during installation, such as a deviation of a few millimeters, the construction personnel can easily adjust the position of the photovoltaic bracket through the elongated hole without the need for complicated operations such as re-drilling or replacing the hook. This greatly improves the efficiency and convenience of installation.

[0026] Furthermore, the structure of vertical and horizontal plates is adopted to accommodate the installation gaps on the roof surface. The structure of the avoidance plate forms a stable force transmission path. The force is transmitted from the photovoltaic bracket to the first connecting plate, then through the horizontal plate to the vertical plate, and then from the vertical plate to the bottom plate, and finally distributed to the supporting structure such as the wooden beams on the roof.

[0027] Furthermore, in photovoltaic support systems, hooks need to withstand various external forces such as the weight of the photovoltaic support itself, wind loads, and snow loads. High-strength bolts have high tensile and shear strength, which can effectively resist these external forces, prevent relative displacement between the various components of the hooks, and ensure the stability of the entire structure.

[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 purpose of this utility model is to provide a height-adjustable photovoltaic bracket hook to solve the problems existing in the prior art. It can be used on small terracotta tile roofs, reduce the breakage of the tiles, and is flexible and convenient to install with adjustable height.

[0040] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0041] Example 1

[0042] This embodiment provides a height-adjustable photovoltaic bracket hook, such as... Figures 1-4 As shown, the system includes a fixed base 10, a central connecting plate 20, and a supporting bending plate 30 arranged vertically from bottom to top. The fixed base 10 includes a base plate 11, a clearance plate 12, and a first connecting plate 13, which are fixedly connected vertically from bottom to top. The base plate 11 is used to fix the system to the wooden beams, rafters, or sheathing boards at the bottom of the tiled roof. The clearance plate 12 is used to be installed in the installation gap of the tiled roof. The lower end of the clearance plate 12 is fixedly connected to the base plate 11, and the upper end of the clearance plate 12 is fixedly connected to the lower end of the first connecting plate 13. The first connecting plate 13 is located above the tiled roof and has a first elongated hole 131. The central connecting plate 20 has a U-shaped groove. A first connecting plate is provided at one end of the U-shaped groove. Hole 21, and a second connecting hole 22 is provided at the other end of the U-shaped groove; the lower end of the supporting bending plate 30 has a second connecting plate 32; the second connecting plate 32 has a second elongated hole 321; the upper end of the first connecting plate 13 and the lower end of the second connecting plate 32 are both slidably disposed in the U-shaped groove in the vertical direction; the first elongated hole 131 of the first connecting plate 13 corresponds to the first connecting hole 21 of the middle connecting plate 20; the second elongated hole 321 of the second connecting plate 32 corresponds to the second connecting hole 22 of the middle connecting plate 20; connecting bolts 40 are provided in the first elongated hole 131 and the first connecting hole 21 and the second elongated hole 321 and the second connecting hole 22, and the threaded end of the connecting bolt 40 is threadedly connected to a connecting nut 41.

[0043] By fixing the base plate 11 to the wooden beams, rafters, or sheathing boards at the bottom of the tiled roof, the force of the entire hook is directly transferred to the roof's supporting structure, rather than being borne by the tiles. By placing the clearance plate 12 in the gap, excessive local pressure caused by direct contact between the hook and the tiles is avoided, thus reducing the possibility of tile breakage. The upper end of the first connecting plate 13 and the lower end of the second connecting plate 32 are both slidably positioned vertically within the U-shaped groove of the middle connecting plate 20. This sliding connection method allows for flexible adjustment of the relative positions of the various components during installation, according to actual needs. For example, if the height of the hook needs to be finely adjusted at the installation site, it is only necessary to slide the first connecting plate 13 and the second connecting plate 32 along the U-shaped groove, without having to disassemble or make complex adjustments to the entire hook. The elongated hole provides a certain displacement space for the bolt, ensuring the reliability of the connection while adjusting the height. The connecting bolt 40 and the connecting nut 41 can tightly fix the various components together after the height is adjusted, ensuring the stability of the hook during use.

[0044] The following are the relevant settings instructions for the fixed base 10:

[0045] Among the optional solutions in this embodiment, the more preferred one is as follows: Figure 1 and Figure 2 As shown, the clearance plate 12 includes a vertical plate 121 and a horizontal plate 122. The lower end of the vertical plate 121 is fixedly connected to the base plate 11, and the horizontal plate 122 and the base plate 11 are both located on the same side of the vertical plate 121. One end of the horizontal plate 122 is fixedly connected to the upper end of the vertical plate 121, and the other end of the horizontal plate 122 is fixedly connected to the lower end of the first connecting plate 13. The structure of the vertical plate 121 and the horizontal plate 122 is used to accommodate the installation gaps on the roof surface. The structure of the clearance plate 12 forms a stable force transmission path. The force transmitted from the photovoltaic bracket to the first connecting plate 13 is transmitted to the vertical plate 121 through the horizontal plate 122, then to the base plate 11 through the vertical plate 121, and finally distributed to the supporting structures such as the wooden beams of the roof.

[0046] Specifically, the included angle between the vertical plate 121 and the bottom plate 11 can be 90°. The included angle between the vertical plate 121 and the horizontal plate 122, as well as the included angle between the horizontal plate 122 and the first connecting plate 13, are set according to the installation gap of the roof surface, such as an acute angle.

[0047] Among the optional solutions in this embodiment, the more preferred one is as follows: Figure 1 and Figure 2As shown, the base plate 11 has at least two elongated holes 111 for fixing, and clamps can be inserted into these holes. The presence of these holes on the base plate 11 provides a flexible and diverse method for fixing the hooks. On small terracotta tile roofs, different roof structures may have different requirements for fixing methods. The clamps can be adjusted according to the shape and size of the roof beams, rafters, or sheathings, better adapting to various irregular support structures. On-site, construction workers can quickly adjust the position and tightness of the clamps according to the actual roof conditions, greatly improving installation efficiency.

[0048] Among the optional solutions in this embodiment, the more preferred one is as follows: Figure 1 and Figure 2 As shown, the base plate 11 also has multiple small round holes 112, through which self-tapping screws can be inserted. This design, combined with the clamp fixing method, provides a more stable installation. The clamp is mainly used to hold the wooden beams, rafters, or roofing boards at the bottom of the roof, while the self-tapping screws further fix the base plate 11 to these supporting structures. This dual fixing method makes the installation of the hooks on the small terracotta roof more secure and reliable. Multiple self-tapping screws fixed to the roof supporting structure through the small round holes 112 can distribute the force borne by the hooks to multiple points, thus avoiding the concentration of force on a few fixing points and reducing the risk of excessive local pressure leading to roof structure damage or hook loosening.

[0049] Specifically, clamps are used to secure the hooks to the wooden or concrete beams of the lower roof; self-tapping screws are used to secure them to the wooden beams, purlins, or roofing panels of the lower roof. These two methods significantly improve the hooks' adaptability to different roof structures.

[0050] The following are the relevant settings for the central connecting plate 20:

[0051] Specifically, the first connecting hole 21 and the second connecting hole 22 of the middle connecting plate 20 are symmetrically arranged.

[0052] The following are the relevant settings for supporting the bending plate 30:

[0053] Among the optional solutions in this embodiment, the more preferred one is as follows: Figure 1 and Figure 3 As shown, the supporting bending plate 30 also includes a horizontal mounting plate 31, one end of which is fixedly connected to the upper end of the second connecting plate 32; the horizontal mounting plate 31 has mounting holes 311. The presence of the horizontal mounting plate 31 provides a stable mounting surface for the photovoltaic bracket. When installing the photovoltaic bracket, the installer can place the connecting part of the bracket directly on the horizontal mounting plate 31 and fix it through the mounting holes 311.

[0054] Among the optional solutions in this embodiment, the more preferred one is as follows: Figure 1 and Figure 3 As shown, mounting hole 311 is an oblong hole. In actual installation sites, various complex situations may be encountered. The oblong hole design facilitates fine-tuning during installation. If it is found that the initial installation position of the photovoltaic bracket and the hook is not perfectly matched during installation, for example, there is a deviation of a few millimeters, the construction personnel can easily adjust the position of the photovoltaic bracket through the oblong hole without the need for complicated operations such as re-drilling holes or replacing hooks. This greatly improves the efficiency and convenience of installation.

[0055] Regarding other related settings:

[0056] Among the optional solutions in this embodiment, the more preferred one is as follows: Figures 1-3 As shown, the first connecting plate 13, the second connecting plate 32, and the middle connecting plate 20 are all U-shaped plates. The U-shaped plate structure has good bending resistance when subjected to external forces. When the photovoltaic bracket is subjected to external forces such as wind load or snow load, the two side plates of the U-shaped plate can effectively resist bending moment, greatly enhance the deformation resistance and load-bearing capacity of the hook, and ensure the overall stability of the hook.

[0057] Specifically, the interlocking structure of the U-shaped plates can greatly reduce the rotation at the connecting bolts 40°, reduce their loosening, and ensure the overall stability of the hook.

[0058] Specifically, the U-shaped plate structure can significantly enhance its cross-sectional moment of inertia, thereby increasing the bending resistance of the component and improving the load-bearing capacity and overall stability of the hook.

[0059] Specifically, during use, the slots of the first connecting plate 13, the second connecting plate 32, and the middle connecting plate 20 must be aligned. This ensures that the middle connecting plate 20 provides supporting bending moment while preventing rotation between adjacent parts, thus improving the load-bearing capacity and overall stability of the hook, and enhancing the anti-loosening properties of the connecting bolts 40.

[0060] Among the optional solutions in this embodiment, the more preferred one is as follows: Figures 1-3 As shown, both the first connecting hole 21 and the second connecting hole 22 are elongated oval holes. The elongated oval structure of the first connecting hole 21 and the second connecting hole 22, together with the structure of the first elongated oval hole 131 and the second elongated oval hole 321, enables a greater height adjustment range.

[0061] Specifically, the interlocking of the elongated holes reduces the difficulty of connecting the 40 pairs of holes of the bolts.

[0062] Specifically, the elongated hole design allows for adjustment of the hook height during installation according to the roof's requirements. This is especially beneficial when the bracket height must meet the ridge height requirements, greatly enhancing the hook's applicability on-site.

[0063] Among the optional solutions in this embodiment, the more preferred one is as follows: Figure 1 and Figure 3 As shown, the second connecting plate 32 is also provided with a third elongated hole 322, which is located on the side of the second elongated hole 321 near the middle connecting plate 20; and the extension direction of the third elongated hole 322 is the same as the extension direction of the second elongated hole 321; the third elongated hole 322 can correspond to the second connecting hole 22 of the middle connecting plate 20. The third elongated hole 322 cooperates with the second elongated hole 321. Compared with the case of only a single elongated hole, the double elongated hole design can better distribute external forces, reduce component damage caused by excessive local stress, and thus extend the service life of the hook.

[0064] In the optional solutions of this embodiment, it is more preferred that the connecting bolt 40 is a high-strength bolt. In the photovoltaic support system, the hook needs to withstand various external forces such as the weight of the photovoltaic support itself, wind load, and snow load. High-strength bolts have high tensile strength and shear strength, which can effectively resist these external forces, prevent relative displacement between the various components of the hook, and ensure the stability of the entire structure.

[0065] Specifically, the connecting bolt 40 is a common galvanized high-strength hexagonal bolt or a common stainless steel high-strength hexagonal bolt. When it is used for connection, it may also include two washers, a spring washer, a nut and other components. The usage method is the same as the existing usage method, and will not be described in detail here.

[0066] Specifically, the usage process of the height-adjustable photovoltaic bracket hook in this embodiment is as follows: First, the first connecting plate 13 and the middle connecting plate 20, as well as the second connecting plate 32 and the middle connecting plate 20, are assembled into a whole using connecting bolts 40 and connecting nuts 41. At this time, the connecting bolts 40 and connecting nuts 41 only need to be slightly tightened. Then, according to the hook positioning point on the roof, the tile surface is lifted, and the base plate 11 of the fixed base 10 is fixed to the wooden beam or concrete beam using clamps, or the hook base plate 11 is fixed to the wooden beam, wooden rafter or wooden board using self-tapping screws. Then, the tile roof is restored, and the clearance plate 12 protrudes from the tile roof through the gap of the overlapping tile surface. Next, the upper bracket is installed and fixed on the horizontal mounting plate 31 of the supporting bending plate 30 using bolts and corresponding nuts, and the bolts are tightened at the same time. Finally, the connection height of the fixed base 10, the middle connecting plate 20 and the supporting bending plate 30 is adjusted and the connecting bolts 40 and connecting nuts 41 are tightened. At this point, the overall installation of the hook is completed.

[0067] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of ​​this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
