Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic brackets, and in particular to a photovoltaic panel and metal roof mounting bracket. Background Art

[0002] Metal roofing is a roofing material that combines a structural layer and a waterproof layer using metal sheets. Widely used in the construction industry, metal roofing is waterproof, durable, and lightweight. It also offers excellent corrosion resistance, durability, and maintainability, making it an ideal roofing material.

[0003] Currently, installing photovoltaic panels on metal roofs requires the use of mounting brackets at the base. Traditional mounting brackets are ineffective. They either lack a tight seal during slot installation, allowing rainwater to seep through the slots, or are bolted directly to raised areas on the roof panel, which can lead to the risk of collapse due to excessive weight. Furthermore, these brackets lack proper tension support after installation, and the impact of rapidly lowering the panels can easily damage them. Furthermore, the mounting brackets are susceptible to loosening and shaking of the fixings when subjected to upward wind, resulting in poor stability.

[0004] Therefore, it is necessary to improve the existing mounting bracket. Summary of the Invention

The connecting plate has a connecting column and is arranged at the upper end of the outer side of the purlin. The elastic structure contacts the connecting column and abuts against the lower end of the inner side of the purlin. The second fixing member is used to fix the photovoltaic panel to the purlin.

[0006] Furthermore, a wire fixing component is provided at the outer lower end of the purlin; The wire fixing component includes a mounting frame fixed to the purlin and an adjustable pressing structure; The adjustable pressing structure includes a wire contact end and a movable adjustment end connected to each other; The wire contact end is arranged inside the mounting frame.

[0009] Furthermore, the purlin and the first fixing member are connected via an adjustable component; The adjustable component includes a plurality of nuts for adjusting the distance between the purlin and the beam.

[0010] Furthermore, a sealing ring is provided at the connection between the first fixing member and the crossbeam.

[0011] Furthermore, the second fixing member includes an edge holder, a connection holder, a screw and a nut; The screw is arranged at the upper end of the purlin.

[0012] Furthermore, the second fixing member includes a plurality of slides, and screws are provided on the tops of the slides. A sliding groove is provided at the outer upper end of the purlin, and the slide plate is slidably connected in the sliding groove.

[0013] Furthermore, the elastic structure includes a limit spring and a damper; The damper is abutted against the connecting column via a limit spring, and the damper is arranged at the lower end inside the purlin.

[0014] The present invention also provides a metal roof with a photovoltaic panel, which is provided with the above-mentioned photovoltaic panel and a metal roof mounting bracket.

[0023] Please refer to Figure 1 、 Figure 2 and Figure 4The second fixing member 4 includes a plurality of slides 41, edge clamps 44, connecting clamps 45, third screws 42, and fixing nuts 43.

[0025] Please refer to Figure 1 and Figure 5 A wire fixing component 5 is also provided at the lower end of the exterior of the purlin 2.

The turning handle 5221 is disposed outside the mounting bracket 51 through the second screw 5222. The guide rod 53 is disposed in a through-hole defined in the mounting bracket 51 and is fixed to the wire contact end 521. A flexible pad is provided at the portion of the wire contact end 521 that contacts the wire.

[0026] The following describes in detail the construction process of the photovoltaic panel and metal roof mounting bracket of this embodiment. S101. A groove is formed on the metal roof to communicate with the crossbeam. After the groove is formed, the lower end of the mounting screw sleeve 11 is placed into the groove to contact the crossbeam. Then, the mounting bolt 12 is placed into the mounting screw sleeve 11 and tightened to fix the mounting bolt 12 to the crossbeam. After the mounting screw sleeve 11 is fixed, glue is applied to the bottom of the sealing ring 15. After the glue is applied, the fixing nut 43 is turned to push the sliding sleeve 14 and the sealing ring 15 downward to fit tightly against the roof, thereby improving the overall stability and safety of the bracket. S102, insert the first screw 13 into the installation screw sleeve 11. After the first screw 13 is installed, first screw the second adjusting nut 162 onto the first screw 13 and adjust it to a suitable height. Then, place the purlin 2 onto the first screw 13 so that the bottom is in contact with the second adjusting nut 162. After the purlin 2 is placed, extend the first adjusting nut 161 inward and screw it onto the first screw 13 to tighten it. This secures the purlin 2. S103. Lower the photovoltaic panel 6 onto the purlin 2. When the photovoltaic panel 6 is lowered, it presses the connecting plate 31, causing the connecting plate 31 to move into the purlin 2. When the connecting plate 31 moves downward, it presses the limit spring 321 and the damper 322. The limit spring 321 and the damper 322 store energy when they shrink and deform, which not only reduces the impact force generated at the moment of dropping, but also improves the wind resistance effect during subsequent use. Move the slide 41 to adjust the third screw 42 to a suitable position, and fix the photovoltaic panel 6 on the purlin 2 through the edge clamp 44, the connecting clamp 45 and the fixing nut 43. S104. After the photovoltaic panel 6 is installed, its connecting wire is passed out from the mounting frame 51. After the connecting wire is straightened, it is placed in the arc groove in the wire contact end 521. The handle 5221 is held by hand to drive the second screw 5222 to rotate. When the second screw 5222 rotates, it will drive the wire contact end 521 to move upward with the cooperation of the guide rod 53 to clamp the connecting wire, which can improve the positioning effect of the connecting wire, reduce the maintenance burden of personnel, and has good flexibility.

[0027] In summary, the present invention is directly fixedly connected to the crossbeam after the roof is grooved, which solves the problem that the traditional mounting bracket is affected by the roof material during the installation process, avoids the situation that the roof is depressed due to excessive load after the bracket is installed, and improves the overall stability and safety of the bracket. The present invention can absorb and offset the collision force generated at the moment of placement of the photovoltaic panel by providing a buffer component, and can also improve the wind resistance of the photovoltaic panel during subsequent use, solving the problem that the traditional mounting bracket cannot provide appropriate tension to the photovoltaic panel from below, and can improve the stable fixation of the photovoltaic panel in a strong wind environment. The present invention solves the problem that the traditional connecting wire directly falls to the roof after being plugged in by providing a wire fixing component. When the roof connecting wire is pulled by wind or by mistake during maintenance by personnel, it is very easy to cause the connecting wire to separate and fall off from the photovoltaic panel, thereby improving the positioning effect of the connecting wire, reducing the maintenance burden of personnel, and having good flexibility.

[0028] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
