Description

Technical Field

[0001] This utility model relates to the field of photovoltaic panel accessories technology, specifically to an adjustable aluminum hook assembly for photovoltaic panels. Background Technology

[0002] With the rapid development of my country's economy, energy demand continues to rise. The large-scale use of traditional fossil fuels (such as coal, oil, and natural gas) not only faces the problem of resource depletion but also leads to serious environmental pollution. The rise of new energy sources has gradually replaced a large amount of fossil fuels, and solar power generation has become an important part of new energy. Currently, most solar power generation is achieved by using sunlight to irradiate solar panels, which has increased the market demand for photovoltaic systems. However, photovoltaic systems require corresponding mounting brackets for support during installation.

[0003] In existing photovoltaic systems installed on tiled roofs, aluminum hooks are used to ensure the photovoltaic modules are securely attached to the roof. For example, Chinese patent document CN208623592U discloses an adjustable leveling hook for solar photovoltaic roof ceramic tiles, comprising a base plate, a support plate, and a mounting plate. The base plate and support plate are both elongated flat plates. One end of the support plate is vertically fixed to one end of the base plate. The mounting plate is an L-shaped elongated plate, with one end movably connected to the support plate, forming a U-shaped structure. Both the base plate and the mounting plate have through holes on their other ends. During installation, the base plate is first fixed to the roof purlins or cement surface using self-tapping screws or expansion screws. Then, the guide rail is fixed to the mounting plate using hex bolts and sliding nuts. However, after the base plate is installed on the roof, the support height adjustment range of the hook is small, and the position of the guide rail installed on the mounting plate cannot be adjusted. When there are different regions or different roof designs, the difficulty of disassembly and assembly will increase significantly. In addition, the arrangement of the wooden beams or load-bearing structures under the roof tiles is different, and a single style of aluminum hook may not be fully applicable. If the installers do not confirm in advance, it will be very inconvenient to use it during installation and fixing. Utility Model Content

[0021] An adjustable aluminum hook assembly for photovoltaic panels includes a fixed base, a supporting arm, and a fixing component mounted on the supporting arm. One end of the supporting arm has a clamping part, and the other end has a mounting part that mates with the fixing component. The supporting arm and the mounting part together form a placement cavity for the photovoltaic tile to extend into. The clamping part is height-adjustable and mounted on the fixed base. The mounting part has an adjustment hole, which is an oblong hole. The fixing component includes a pressure block and a locking bolt. The pressure block is slidably disposed in the adjustment hole by the locking bolt. The pressure block engages with one side of a guide rail. The locking bolt is used to fix the guide rail to the mounting part.

[0022] With its height-adjustable clamping section and sliding, adjustable, and fixed clamping block design, this system is compatible with roof tiles of varying thicknesses (such as terracotta and glazed tiles) and photovoltaic panel rails of different specifications, solving the installation mismatch problem caused by traditional hooks due to tile size differences. The clamping block is installed on the adjustment hole via locking bolts and adjusting nuts. Loosening the adjusting nut allows the clamping block to slide within the adjustment hole, facilitating later adjustments to the photovoltaic panel angle or replacement of damaged parts without disassembling the entire structure, making operation simple and convenient.

[0023] The present invention will be further described and illustrated below with reference to specific embodiments and the accompanying drawings:

[0024] Please refer to Figures 1 to 4An adjustable aluminum hook assembly for photovoltaic panels includes a fixed base 10, a support arm 20, a fixing component 30, and an adjusting bolt 40. The fixed base 10 is fixed to a wooden beam or load-bearing structure under the roof tiles by screws or other means. One end of the support arm 20 is connected to the fixed base 10 and fixed by the adjusting bolt 40. The other end of the support arm 20 is connected to the fixing component 30.

[0025] The fixed base 10 includes a mounting platform 11 and a mounting plate 12. The mounting plate 12 has a plate-like structure, which allows the bottom surface of the mounting plate 12 to have a large contact area with the surface of the roof. The mounting plate 121 is provided on its surface, and the mounting holes 121 are used to fix the mounting plate 12 to the roof with fasteners such as screws. The mounting platform 11 is located on one side of the mounting plate 12. The mounting platform 11 and the mounting plate 12 are composed of an integrally formed aluminum profile. The mounting platform 11 has serrated grooves 111 on both sides, and the grooves 111 are provided with limiting grooves with a certain inclination angle.

[0026] One end of the support arm 20 is provided with a pressing part 21, and the other end is provided with a mounting part 22 that cooperates with the fixing component 30. The support arm 20 and the mounting part 22 enclose a placement cavity 23, which is U-shaped and is used to accommodate the tile extending into it to ensure stability when installed on the tile. The surface of the pressing part 21 is provided with an assembly hole 211 through which the rod of the adjusting bolt 40 passes. The end of the pressing part 21 that cooperates with the mounting platform 11 is provided with a mating part 24. The mating part 24 is provided with a threaded hole 242 that aligns with the assembly hole 211 and is used for threaded connection of the adjusting bolt 40.

[0027] The surface of the mounting part 22 is provided with adjustment holes 221 and a plurality of anti-slip teeth 222 arranged in a continuous array along the length direction. The anti-slip teeth 222 are small protrusions, and their shape can be triangular, rectangular, or other shapes suitable for increasing friction. When the guide rail 50 is fixed by the fixing component 30, the anti-slip teeth 222 abut against the bottom of the guide rail 50, which can effectively prevent the guide rail 50 from sliding during installation or use, ensuring the stability of the guide rail 50.

[0028] The inner side of the mating part 24 is provided with serrated teeth 241 that match the slot 111 along its axial direction. The side of the teeth 241 that mates with the slot 111 is provided with a certain slope, which makes it easier to align and snap into the slot 111 during installation, reducing installation difficulty and improving installation efficiency. In addition, the limiting groove of the slot 111 can provide a better biting effect, making the fit between the teeth 241 and the slot 111 tighter and more stable.

[0029] The adjusting bolt 40 includes a head and a screw portion. The diameter of the head of the adjusting bolt 40 is smaller than the diameter of the mounting hole 211. The head of the adjusting bolt 40 can pass through the mounting hole 211 and be disposed in the clamping part 21, and is threadedly connected to the threaded hole 242 on the mating part 24. The screw portion of the adjusting bolt 40 passes through the threaded hole 242 and is disposed on the top of the mounting platform 11. The top surface of the mounting platform 11 is provided with a top holding surface 112, which is used to thread-abut against the screw portion of the adjusting bolt 40.

[0030] In the process of adjusting the height of the clamping part, the following steps are taken: After the locking teeth 241 of the mating part 24 are engaged with the slot 111 of the mounting platform 11, the adjusting bolt 40 is turned clockwise. The tail end of the screw part of the adjusting bolt 40 is tightly abutted against the top support surface 112, which provides stable support. As the screw part of the adjusting bolt 40 is further screwed in, the pressure on the top support surface 112 increases. Due to the abutting action between the tail end of the screw part of the adjusting bolt 40 and the top support surface 112, the mating part 24 is pushed upward. The locking teeth 241 on the mating part 24 are tightly engaged with the slot 111 on the mounting platform 11. Even with external force, the locking teeth 241 cannot be separated from the slot 111, making the engagement between the locking teeth 241 and the slot 111 even tighter and further enhancing the stability of the structure.

[0031] When the adjusting bolt 40 is turned counterclockwise, the screw part of the adjusting bolt 40 will gradually unscrew out of the threaded hole 242 of the mating part 24. The contact between the tail end of the screw part and the top holding surface 112 of the mounting platform 11 will gradually weaken. The retaining teeth 241 on the mating part 24 and the retaining groove 111 on the mounting platform 11 will return to normal engagement. At this time, the mating part 24 can be removed from the side of the fixed platform without jamming or sudden loosening. This can greatly shorten the installation and disassembly time and improve the operating efficiency.

[0032] This utility model achieves flexible adjustment of the height of the pressing part 21 through the cooperation of the locking teeth 241 and the locking groove 111 and the cooperation of the adjusting bolt 40, which can adapt to tiles of different thicknesses or other installation requirements. This design not only improves versatility and adaptability, but also simplifies the installation process.

[0033] The fixing component 30 includes a pressure block 31, a locking bolt 32, and an adjusting nut 33. The pressure block 31 includes a fixing part 311 and a snap-fit ​​part 312. The fixing part 311 has a fixing hole 3111 for the locking bolt 32. The locking bolt 32 passes through the fixing part 311 and the adjusting hole 321 and is screwed into the adjusting nut 33. One end of the snap-fit ​​part 312 has a snap-fit ​​groove 3121. The snap-fit ​​groove 3121 is consistent with the thickness of the side plate of the guide rail 50, ensuring that the guide rail 50 can be tightly snapped into the snap-fit ​​groove 3121, thereby improving the stability of the guide rail 50.

[0034] The installation process of the guide rail 50 is as follows: First, place one side of the photovoltaic panel guide rail 50 into the snap-fit ​​groove 3121 of the pressure block 31, ensuring that the guide rail 50 fits tightly with the snap-fit ​​groove 3121. Pass the locking bolt 32 through the fixing part 311 of the pressure block 31 and the adjustment hole 221 of the support arm 20. Tighten the adjusting nut 33 to firmly fix the pressure block 31 onto the support arm 20, thereby fixing the guide rail 50 onto the support arm 20. When it is necessary to adjust the position of the guide rail 50, the adjusting nut 33 can be loosened, and the position of the pressure block 31 can be moved in the adjustment hole 221 as needed to adjust the position of the guide rail 50. After the adjustment is completed, the adjusting nut 33 is tightened again to ensure the stability of the pressure block 31 and the guide rail 50. The operation is simple and convenient. Moreover, it can also be installed according to different heights of the side of the photovoltaic panel guide rail 50, that is, the snap-fit ​​groove 3121 of the pressure block 31 can be adjusted and matched, making it more versatile.

[0035] The bottom end of the fixing part 311 is provided with an abutment block 313, which abuts against the surface of the mounting part 22. A clamping gap is reserved between the abutment block 313 and the surface of the mounting part 22, so that the position of the pressure block 31 can be adjusted by loosening the adjusting nut 33 that cooperates with the locking bolt 32 during the installation process, thereby adapting to the installation of photovoltaic panel guide rails 50 of different thicknesses. The clamping gap can provide a certain buffer space to prevent damage to components due to excessive clamping during the installation process.

[0036] The clamping part 21 has a first window 212 that extends through the left and right sides and communicates with the assembly hole 211 and the threaded hole 242. Through the first window 212, the user can directly observe the installation status of the adjusting bolt 40 and ensure that the adjusting bolt 40 is correctly installed and in the appropriate position. The mating part 24 and the top holding surface 112 of the mounting platform 11 form a second window 243. Through the second window 243, the user can directly observe the mating situation between the mating part 24 and the mounting platform 11 and ensure that the retaining teeth 241 and the retaining groove 111 are correctly engaged. The user can also observe the engagement position of the retaining grooves 111. The user can observe the direction of the adjusting bolt 40 by combining the first window 212 and the second window 243, which reduces the difficulty of operation.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
