Description

Technical Field

[0002] As the global energy structure shifts towards clean energy, distributed photovoltaic (PV) power generation systems are increasingly being used in residential settings. Balconies, as an effective space available in urban residences, are gradually becoming an important scenario for PV installation.

[0003] Existing balcony photovoltaic (PV) mounting systems still have many shortcomings in practical applications. Traditional PV mounting systems are mostly designed with fixed dimensions, requiring customization based on the specifications of specific PV modules. They cannot flexibly adapt to PV panels of different power and size, forcing users to replace the entire mounting system when changing modules, increasing operating costs. Balcony wall thickness varies, and the mounting holes or fixing structures of existing systems are mostly pre-sized, unable to be adjusted according to wall thickness, limiting their application range. Traditional mounting system installation relies on drilling holes for expansion bolts, requiring specialized tools and construction personnel, and can damage the wall structure, thus reducing the applicability of PV mounting systems.

The second telescopic component 12 includes an inner telescopic short arm 121 and an outer telescopic short arm 122 that is slidably sleeved on the outside of the inner telescopic short arm 121. An adjustment component 3 is provided on the outer telescopic short arm 122 to restrict the outer telescopic short arm 122 from sliding outside the inner telescopic short arm 121. Specifically, both the outer telescopic long arm 111 and the inner telescopic long arm 112 are vertically arranged hollow square tubular structures; the two sets of frame bodies 1 are the left support and the right support, which are set in mirror image opposite each other. By adjusting the distance between the left support and the right support, it can be adapted to the installation of rectangular photovoltaic modules 2 of different widths. Please see Figure 1 , Figure 2 and Figure 3 The inner telescopic long arm 112 and the outer telescopic long arm 111 are provided with slots 7 along the axial direction. The side wall of the photovoltaic module 2 is located inside the slots 7. In this way, the distance between the two sets of frame bodies 1 can be adjusted based on the width of the installed photovoltaic module 2, so that this photovoltaic bracket can be adapted to the installation of rectangular photovoltaic modules 2 of different widths.

[0022] Please see Figure 1 , Figure 2 and Figure 3 The second telescopic component 12 also includes a short arm fixing screw 123. One end of the inner telescopic short arm 121 is fixedly connected to the top end of the inner telescopic long arm 112. The other end of the inner telescopic short arm 121 is slidably fitted with an outer telescopic short arm 122. A threaded sleeve is threadedly fitted on the outer side of the short arm fixing screw 123. The threaded sleeve is fixedly connected to the top of the inner telescopic short arm 121. A rotating tube is rotatably fitted on the end of the short arm fixing screw 123 away from the first telescopic component 11. The rotating tube is fixedly connected to the top of the outer telescopic short arm 122. A groove is opened on the top of the outer telescopic short arm 122. The threaded sleeve is slidably connected to the inside of the groove. Specifically, the second telescopic component 12 is a horizontally arranged hollow square tube structure; the short arm fixing screw 123 includes a screw part and a long rod part, a threaded sleeve is threadedly fitted in the screw part area, and a rotating tube is rotatably connected to the outside of the long rod part; two telescopic corrugated covers can be fitted on the outside of the short arm fixing screw 123 to improve the dustproof effect of the short arm fixing screw 123. Since the telescopic corrugated cover is an existing technical structure, its usage form, installation method and connection method are all existing technical means, and this application will not elaborate on them in detail.

[0023] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The adjustment assembly 3 includes a ratchet support 31 installed at the bottom of the outer telescopic short arm 122. A pair of ratchet wheels 32 are provided on the ratchet support 31. A storage rod is fixedly connected between the two ratchet wheels 32. A steel cable 33 is fixedly wound on the storage rod. A small hole 4 is opened at the top of the ratchet support 31 to pass through the outer telescopic short arm 122. The end of the steel cable 33 passes through the small hole 4, the interior of the outer telescopic short arm 122, the interior of the inner telescopic short arm 121, and the interior of the inner telescopic long arm 112 in sequence, and is fixedly connected to the bottom wall inside the outer telescopic long arm 111.

The rotatable wheel is used to reduce the friction of the steel cable 33 in contact with other objects and to change the force or direction of movement of the steel cable 33. The rotatable wheel is generally set at the bend where the direction of movement of the steel cable 33 changes.

[0024] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 A shaft is fixedly connected to one side of the ratchet 32.

Specifically, the ratchet support 31 has a through-hole at the corresponding position of the shaft, and the shaft is rotatably connected inside the shaft hole. One end of the telescopic handle 17 has a convex groove that matches the protrusion, thus facilitating the removal and installation of the telescopic handle 17. The telescopic handle 17 drives the protrusion to rotate, and the protrusion drives the ratchet 32 ​​to rotate via the shaft. The ratchet 32 ​​uses a storage rod to wind or release the steel cable 33, and the steel cable 33 pulls the outer telescopic arm 111 and the inner telescopic arm 112 to extend and retract relative to each other. The ratchet 32 ​​and the ratchet support 31 are existing technical structures and equipment, and their specific connection methods, specific forms and usage methods are all existing technical means, which will not be described in detail in this application.

The other end of the support seat screw 5 is threaded with an inner support seat 6. Specifically, the inner support seat 6 can be held in place by hand and then the support seat screw 5 can be rotated, or the inner support seat 6 can be fixed by the friction of the inner support seat 6 pressing against the wall panel and then the support seat screw 5 can be rotated; the support seat screw 5 and the inner support seat 6 form the inner support assembly; Specifically, the mounting plate has a through-hole axial hole 2 on the side opposite to the second protrusion, and the second shaft is rotatably connected inside the second shaft hole. The second protrusion is adapted to the convex groove on the telescopic handle 17. The cross-section of the convex groove is a square cavity. The cross-sections of the first protrusion and the second protrusion are square structures. In this way, the ratchet support 31 and the support screw 5 can share a telescopic handle 17. When using the telescopic handle 17, it is only necessary to connect the convex groove on the telescopic handle 17 with the second protrusion or the first protrusion, and then rotate the telescopic handle 17. The telescopic handle 17 can drive the support screw 5 or the ratchet 32 ​​to rotate.

[0026] Specifically, a telescopic corrugated cover can be fitted on the outside of the support base screw 5. The two ends of the telescopic corrugated cover are fixedly connected between the inner support base 6 and the mounting plate, respectively. Since the telescopic corrugated cover is an existing technical structure, its usage, installation method and connection method are all existing technical means, and this application will not elaborate on them.

[0027] Specifically, several fixing holes can be provided on the first telescopic component 11 of the frame 1 to fix the frame or edge of the photovoltaic module 2 to the frame 1, thereby further improving the stability of the photovoltaic module 2 installation.

[0030] Please see Figure 1 A connecting plate 13 is fixedly connected between the two external telescopic long arms 111, and the connecting plate 13 is located at the bottom of the photovoltaic module 2; Specifically, the bottom end of the telescopic arm 111 is provided with a drain outlet to drain rainwater that has seeped into the first telescopic component 11; the connecting plate 13 is used to fix the two sets of frame bodies 1 so that the photovoltaic bracket as a whole forms a U-shaped structure, further improving the strength of the photovoltaic bracket and enhancing the stability of the photovoltaic module 2 installation.

[0031] Please see Figure 1 , Figure 2 and Figure 3 A hollow adapter 14 is fixedly sleeved between the top end of the inner telescopic long arm 112 and one end of the inner telescopic short arm 121, and an upper limit component 15 is installed at the bottom of the hollow adapter 14. Specifically, during the installation of the photovoltaic bracket, the surface of the upper limit positioner 15 abuts against the wall surface to achieve the positioning of the upper end of the photovoltaic bracket. Through the cooperation of the upper limit positioner 15 and the lower limit positioner 9, the installation direction of the photovoltaic bracket is ensured to be vertical, and the bracket 1 is quickly positioned during installation.

[0032] The primary application of this photovoltaic (PV) bracket is on balcony walls. However, due to its telescopic adjustment design, it is also suitable for installation on other types of walls such as perimeter walls and parapet walls. The specific installation scenario will depend on the actual site conditions. The working process of this PV bracket is as follows: The long sides of the rectangular photovoltaic module 2 are respectively inserted into the slots 7 of the first telescopic components 11 of the two sets of frames 1 to complete the assembly of the photovoltaic bracket and the photovoltaic module 2; preferably, the connecting plate 13 can be installed in the fixing holes of the first telescopic components 11 of the two sets of frames 1 by bolts to further improve the stability of the photovoltaic module 2 installation.

[0033] Place the assembled photovoltaic bracket vertically, ensuring the upper surface of the bottom plate 8 of the photovoltaic bracket contacts the lower surface of the wall; ensure the lower limit member 9 of the bottom plate 8 abuts against the wall surface to achieve initial positioning of the lower part of the photovoltaic bracket; adjust the height of the first telescopic component 11 so that the surface of the second telescopic component 12 of the photovoltaic bracket contacts the upper surface of the wall; ensure the upper limit member 15 abuts against the wall surface to achieve positioning of the upper end of the photovoltaic bracket; adjust the horizontal extension distance of the second telescopic component 12 to adapt to the thickness of the wall; after the position is determined, insert the short arm fixing screw 123 to lock the relative position of the inner telescopic short arm 121 and the outer telescopic short arm 122; adjust the relative position of the inner support base 6 and the wall, and simultaneously lock the height of the first telescopic component 11 to ensure the stable installation of the photovoltaic bracket.
