Description

Technical Field

[0001] This utility model relates to the field of maintenance cable tray technology, and in particular to a maintenance cable tray for photovoltaic roofs. Background Technology

[0002] With the rapid development of photovoltaic power generation technology, photovoltaic roof systems have become an important application direction due to their advantages such as saving land, high integration with buildings, and aesthetics. However, photovoltaic roofs face challenges such as component cleaning, inspection, and cable maintenance during long-term operation.

[0003] A search revealed Chinese patent CN218406122U, which discloses a maintenance cable tray for photovoltaic roofs. The tray includes a load-bearing bridge deck, columns, and C-shaped support feet. The load-bearing bridge deck comprises slotted aluminum profiles and hollow rectangular aluminum profiles. Two slotted aluminum profiles are arranged with their slots facing each other, and each slot is combined with one of the two sides of the hollow rectangular aluminum profile. The columns include rectangular aluminum profiles and right-angled trapezoidal aluminum profiles. The columns are respectively positioned at the four corners below the load-bearing bridge deck. C-shaped support feet are located below the columns. Each C-shaped support foot comprises a C-shaped aluminum profile and a rubber pad, with the rubber pad located on the inner side of the C-shaped aluminum profile.

[0004] Based on the above search results combined with existing technologies, the findings were as follows:

[0005] While the aforementioned patent can provide a walking path during the inspection and maintenance of photovoltaic panels, it uses C-shaped support feet for clamping and support. However, C-shaped support feet can only adapt to the crests in specific roof panels, which limits its use and makes it unsuitable for different roofs. This results in poor practicality and thus certain limitations. Utility Model Content

[0006] To address the aforementioned technical issues, this utility model proposes a maintenance cable tray for photovoltaic roofs, which enables stable fixed installation and ensures stability during use.

[0007] The technical solution to achieve the purpose of this utility model is as follows: a maintenance cable tray for photovoltaic roofs, including a pair of fixed seats, with connecting ear plates fixedly installed at both ends of the bottom of the fixed seats, I-shaped seats provided on the surface of the pair of fixed seats, two pairs of L-shaped limiting plates symmetrically fixedly installed on the outer side of the I-shaped seats, and walkway plates fixedly installed on the surface of the I-shaped seats, and also including fixing components.

[0008] The fixing component is mounted on the I-shaped base.

[0009] The fixing component includes two pairs of U-shaped clamping plates fixedly installed at the bottom of the I-shaped base. The U-shaped clamping plates are slidably engaged with the fixing base. The I-shaped base has a sliding groove. A bidirectional threaded rod is rotatably installed inside the sliding groove. A hexagonal rotating block is fixedly installed at one end of the bidirectional threaded rod.

[0010] In some embodiments, a pair of movable plates are threadedly connected to the bidirectional threaded rod, the movable plates are slidably engaged with the sliding groove, a pair of insert rods are fixedly installed on one side of each movable plate, and a pair of insertion holes are provided on each fixed base, the insert rods are slidably engaged with the insertion holes.

[0011] In some embodiments, a connecting plate one and a connecting plate two are fixedly installed on both sides of the walkway plate, respectively. A plurality of protrusions are fixedly installed on the connecting plate one at equal intervals, and a plurality of slots are opened on the connecting plate two at equal intervals. The protrusions and the slots slide together.

[0012] In some embodiments, the walkway slab has multiple through holes at equal intervals, and multiple anti-slip strips are fixedly installed at equal intervals on the surface of the walkway slab.

[0013] Compared with existing technologies, the significant advantages of this invention are:

[0014] Firstly, this utility model, through the setting of a fixed base and connecting ear plate, can fix the fixed base to the photovoltaic support frame with bolts, without the need for cooperation with the roof, thereby improving the practicality of the device. Secondly, through the setting of a U-shaped clamping plate, the I-shaped base can be pre-fixed, and then the moving plate and the insertion rod are moved by the double-line threaded rod, so that the insertion rod and the insertion hole are interlocked, thereby further improving the stability of the fixed installation of the I-shaped base, thereby improving the stability of the walkway plate installation, and thus improving the stability and safety of the device during use.

[0015] Secondly, this utility model, through the cooperation of the U-shaped card plate, the movable plate and the plug rod, not only makes operation convenient, but also greatly improves the stability of the fixed installation of the I-shaped base, thereby improving the stability of the walkway board and ensuring the safety of construction personnel when walking.

[0016] This solves the problem that while existing technologies can provide a walking path for inspecting and maintaining photovoltaic panels, they rely on C-shaped support feet for clamping and support. However, C-shaped support feet can only adapt to the crests in specific roof panels, resulting in limited use and poor practicality for different roof types. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0025] This utility model provides an improved maintenance cable tray for photovoltaic roofs. The technical solution of this utility model is as follows:

[0026] like Figures 1-4 As shown, a maintenance cable tray for photovoltaic roofs includes a pair of fixed bases 1, with connecting lugs 2 fixedly installed at both ends of the bottom of each fixed base 1. I-shaped bases 4 are provided on the surface of each pair of fixed bases 1, and two pairs of L-shaped limiting plates 11 are symmetrically fixedly installed on the outer side of each I-shaped base 4. A walkway plate 12 is fixedly installed on the surface of the I-shaped base 4. The cable tray also includes a fixing component. The connecting lugs 2 facilitate the connection between the fixed bases 1 and the photovoltaic mounting frame, providing a stable foundation for the installation of the I-shaped base 4 and the walkway plate 12. Furthermore, the fixing component improves the stability of the fixed installation of the I-shaped base 4, thereby ensuring the stability of the walkway plate 12 during use.

[0027] The fixing component is set on the I-shaped base 4.

[0028] The fixing component includes two pairs of U-shaped clamping plates 5 fixedly installed at the bottom of the I-shaped base 4. The U-shaped clamping plates 5 are slidably engaged with the fixing base 1. The I-shaped base 4 is provided with a sliding groove 6. A bidirectional threaded rod 7 is rotatably installed inside the sliding groove 6. A hexagonal rotating block 8 is fixedly installed at one end of the bidirectional threaded rod 7. The sliding groove 6 provides support for the installation of the bidirectional threaded rod 7. The hexagonal rotating block 8 ensures that the rotation of the threaded rod can be easily controlled during installation, thereby realizing the control of the fixing component.

[0029] Furthermore, a pair of movable plates 9 are connected to the bidirectional threaded rod 7 by threads. The movable plates 9 slide with the sliding groove 6. A pair of insert rods 10 are fixedly installed on one side of each movable plate 9. A pair of insertion holes 3 are opened on each fixed base 1. The insert rods 10 slide with the insertion holes 3. By using the movable plates 9 and insert rods 10, they are interlocked through the insertion holes 3, thereby improving the stability of the fixed installation of the I-shaped base 4.

[0030] Furthermore, connecting plate one 13 and connecting plate two 15 are fixedly installed on both sides of the walkway 12, respectively. Multiple protrusions 14 are fixedly installed at equal intervals on connecting plate one 13, and multiple slots 16 are opened at equal intervals on connecting plate two 15. The protrusions 14 and slots 16 slide together. Multiple walkway 12 can be spliced ​​together by connecting plate one 13 and connecting plate two 15, so as to facilitate adjustment according to the required passage length and ensure that there are no gaps at the splicing point, thus affecting the movement of construction personnel.

[0031] Furthermore, multiple through holes 18 are equidistantly provided on the walkway 12, and multiple anti-slip strips 17 are fixedly installed equidistantly on the surface of the walkway 12. The through holes 18 ensure that water will not accumulate on the walkway 12 in rainy weather, while the anti-slip strips 17 effectively increase the friction of the surface of the walkway 12, thereby ensuring that construction personnel will not slip when walking, thus affecting the overall safety of the device.

[0032] The specific working method is as follows: After the photovoltaic panel mounting frame is fixed, the fixing seat 1 is fixed to the frame with bolts through the connecting ear plate 2. After the fixing seat 1 is fixed, the I-shaped seat 4 is pre-locked and fixed to the fixing seat 1 through the U-shaped clamp plate 5. After the I-shaped seat 4 is fixed, the hexagonal rotating block 8 is used to rotate the bidirectional threaded rod 7 through the external hexagonal wrench, thereby moving the moving plate 9 and the insertion rod 10, so as to realize the insertion rod 10 and the insertion hole 3 to lock together, further improving the fixed installation effect of the I-shaped seat 4, thereby improving the overall stability of the installation. Finally, the walkway plate 12 is fixed and installed to the I-shaped seat 4 with fixing bolts. At this point, the entire maintenance cable tray installation is completed.

[0033] The technical means disclosed in this utility model are not limited to those described above, but also include technical solutions composed of equivalent substitutions of the above technical features. Matters not covered in this utility model are common knowledge to those skilled in the art.
