Technical Field
[0001] This utility model relates to the field of photovoltaic equipment installation technology, specifically a quick-installation bracket structure for a rooftop photovoltaic system. Background Technology
[0002] With the rapid development of the new energy industry, solar energy, as a clean and renewable energy source, is being widely used, and the number of rooftop photovoltaic systems being installed is increasing day by day. In the installation process of rooftop photovoltaic systems, the support structure plays an important role in supporting photovoltaic modules, and its installation efficiency and stability directly affect the construction progress and safety of the entire photovoltaic system.
[0003] Currently, most rooftop photovoltaic (PV) mounting systems on the market use fixed-size frame structures, with PV modules directly bolted to the brackets. This traditional structure has the following problems: different specifications of PV modules, such as size, require matching special brackets, and the entire bracket needs to be replaced when replacing modules, resulting in insufficient versatility and increased equipment procurement and maintenance costs; fixing PV modules often relies on multiple scattered bolts, requiring point-by-point alignment and tightening during installation, which is not only time-consuming and labor-intensive, but may also lead to uneven stress on the modules due to inconsistent bolt tightness, affecting their service life; traditional brackets are mostly integrated rigid structures, which are large in size and difficult to fold, occupying a lot of space during transportation and increasing logistics costs; at the same time, rooftop installation space is often limited, and the bracket structure also increases the difficulty of on-site handling.
[0004] Therefore, it is necessary to propose a rapid installation support structure for rooftop photovoltaic systems. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides a quick-installation bracket structure for rooftop photovoltaic systems. It has the advantages of being adaptable to different photovoltaic modules, simplifying the installation process, improving transportation convenience, and ensuring structural stability, thus solving the problems mentioned in the background technology.
[0006] This utility model provides the following technical solution: a quick-installation bracket structure for a rooftop photovoltaic system, comprising a hollow base, a support plate, and photovoltaic modules:
[0007] A support plate is provided on the upper surface of the hollow base, and a photovoltaic module is attached to the upper surface of the support plate.
[0008] The bearing plate has slots on both sides, and a bidirectional lead screw is rotatably fitted inside the slot. A moving block is threaded onto the outer surface of the bidirectional lead screw. An L-shaped clamping plate is fixedly installed on the upper surface of the moving block. An insertion slot is opened on both sides of the L-shaped clamping plate, and an auxiliary clamping plate is inserted into the insertion slot. The auxiliary clamping plate and the interior of the L-shaped clamping plate are engaged with the edges and corners of the photovoltaic module.
[0009] Preferably, connecting columns are fixedly installed at both ends of the upper surface of the hollow base, and hinge blocks are installed at the ends of the connecting columns. The lower surface of the bearing plate is installed with the hinge blocks.
[0010] Preferably, U-shaped plates are snapped onto both sides of the upper surface of the hollow base, and expansion bolts are connected to the upper part of the U-shaped plates. The expansion bolts pass through the hollow part of the hollow base and connect to the external mounting surface.
[0011] Preferably, the outer surface of the movable block slides into the interior of the slot.
[0012] Preferably, the insertion slot has a connecting hole inside, and the auxiliary card plate is threadedly connected to the insertion part of the insertion slot with a connecting bolt, and the connecting bolt is threadedly connected to the inside of the connecting hole.
[0013] Preferably, the end of the bidirectional lead screw is fixedly connected to a toothed throttle, the outer surface of the toothed throttle is engaged with a limiting toothed ring, the side of the bearing plate is provided with an insertion hole, and the side end of the limiting toothed ring is inserted into the inside of the insertion hole.
[0014] Compared with the prior art, the present invention has the following beneficial effects:
[0015] 1. This type of rooftop photovoltaic system quick-installation bracket structure uses bidirectional screw rods installed in the slots on both sides of the support plate. These screw rods, along with a moving block, drive the L-shaped clamping plate to move, allowing for rapid adjustment of the L-shaped clamping plate's position to accommodate photovoltaic modules of different sizes, thus achieving snap-fit fixation of the photovoltaic module's edges. Simultaneously, auxiliary clamping plates are inserted into the L-shaped clamping plate's slots to further secure the photovoltaic module's corners, enhancing the fixing effect. The entire process requires no complex operations, significantly improving installation efficiency.
[0016] 2. This type of rooftop photovoltaic system quick-installation bracket structure features U-shaped plates snapped onto both sides of the upper surface of the hollow base. These plates, along with expansion bolts passing through the hollow portion of the base, connect to the external mounting surface. This not only ensures the stability of the hollow base installation but also facilitates pre-positioning of the base through the snap-fit structure of the U-shaped plates, simplifying the installation process. Furthermore, hinge blocks are installed at the ends of the connecting columns on both sides of the upper surface of the hollow base. The lower surface of the support plate is installed with the hinge blocks, allowing the support plate and the hollow base to rotate via the hinge blocks. This enables the bracket structure to be stored away, reducing the overall space occupied and facilitating storage and handling during transportation, thus improving the portability of the device.
[0017] 3. This type of rooftop photovoltaic system quick-installation bracket structure features a sliding fit between the outer surface of the moving block and the inside of the slot, ensuring smooth movement of the moving block under the drive of the bidirectional screw and preventing the L-shaped clamp from shifting. The auxiliary clamp is threadedly connected to the connecting hole in the insertion slot via connecting bolts, which can firmly fix the auxiliary clamp onto the L-shaped clamp and prevent it from loosening. The toothed handle at the end of the bidirectional screw meshes with the limiting toothed ring, and the side end of the limiting toothed ring is inserted into the insertion hole on the side of the bearing plate, which can limit the rotation of the bidirectional screw and prevent the L-shaped clamp from changing position due to external force, thus ensuring the stability of the overall structure.

[0028] 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.
[0029] Please see Figure 1-4 A quick-installation bracket structure for a rooftop photovoltaic system includes a hollow base 1, a support plate 2, and photovoltaic modules 4.
[0030] A support plate 2 is provided on the upper surface of the hollow base 1, and a photovoltaic module 4 is attached to the upper surface of the support plate 2.
[0031] Both sides of the support plate 2 have slots 210, and a bidirectional lead screw 220 is rotatably fitted inside the slots 210. A moving block 211 is threaded onto the outer surface of the bidirectional lead screw 220. An L-shaped clamping plate 230 is fixedly installed on the upper surface of the moving block 211. Both sides of the L-shaped clamping plate 230 have insertion slots 231, and an auxiliary clamping plate 240 is inserted into the insertion slots 231. The auxiliary clamping plate 240 and the interior of the L-shaped clamping plate 230 engage with the edges and corners of the photovoltaic module 4.
[0032] By rotating the bidirectional lead screw 220, the screw is threaded into the moving block 211, causing the moving block 211 to slide within the slot 210, thereby adjusting the position of the L-shaped clamping plate 230. The L-shaped clamping plate 230 is inserted into the auxiliary clamping plate 240 through the insertion slot 231, forming a surrounding structure for the edges and corners of the photovoltaic module 4.
[0033] Specifically, the combination design of the L-shaped clamp 230 and the auxiliary clamp 240 enables rapid positioning and fixing of photovoltaic modules 4 of different sizes, which enhances the clamping stability, reduces installation steps, and improves efficiency.
[0034] like Figure 1 As shown, in this embodiment, connecting posts 130 are fixedly installed at both ends of the upper surface of the hollow base 1, and hinge blocks 140 are installed at the ends of the connecting posts 130. The lower surface of the bearing plate 2 is installed with the hinge blocks 140.
[0035] The connecting column 130 is fixed to the hollow base 1, and the hinge block 140 at its end is connected to the bearing plate 2 through a rotating structure, so that the bearing plate 2 can rotate around the hinge block 140.
[0036] Specifically, it allows the support plate 2 to be folded to fit snugly against the hollow base 1 during transportation or storage, reducing the overall space occupied and improving portability.
[0037] like Figure 1 and Figure 2 As shown, in this embodiment, U-shaped plates 110 are snapped onto both sides of the upper surface of the hollow base 1. Expansion bolts 120 are connected to the upper part of the U-shaped plates 110, and the expansion bolts 120 pass through the hollow part of the hollow base 1 to connect with the external mounting surface.
[0038] U-shaped plates 110 are snapped onto both sides of the hollow base 1, and are fastened to the roof or other external mounting surfaces by means of expansion bolts 120 passing through the hollow structure of the hollow base 1.
[0039] Specifically, the snap-fit design of the U-shaped plate 110 enables the quick pre-positioning of the hollow base 1, and the expansion bolts 120 ensure that the base is firmly installed. At the same time, the hollow structure reduces the overall weight and reduces the load-bearing pressure on the installation surface.
[0040] like Figure 3 As shown, in this embodiment, the outer surface of the movable block 211 slides into the interior of the slot 210.
[0041] The size of the movable block 211 matches the inner wall of the slot 210, restricting the movable block 211 to slide only along the direction of the slot 210, thus preventing the movable block 211 from shifting when the bidirectional lead screw 220 rotates.
[0042] Specifically, this ensures the stability of the L-shaped card plate 230 during its movement, prevents the photovoltaic module 4 from becoming loose due to offset, and improves structural reliability.
[0043] like Figure 3 As shown, the insertion slot 231 in this embodiment has a connecting hole 232 inside. The auxiliary card plate 240 is threadedly connected to the insertion part of the insertion slot 231 by a connecting bolt 241. The connecting bolt 241 is threadedly connected to the internal thread of the connecting hole 232.
[0044] After the auxiliary plate 240 is inserted into the insertion slot 231, the two are fixed by passing the connecting bolt 241 through the auxiliary plate 240 and threading it into the connecting hole 232.
[0045] Specifically, it prevents the auxiliary clamp 240 from loosening or falling off during use and enhances the clamping strength of the four corners of the photovoltaic module.
[0046] like Figure 4 As shown, in this embodiment, a toothed throttle 221 is fixedly connected to the end of the bidirectional lead screw 220. A limiting toothed ring 3 engages with the outer surface of the toothed throttle 221. An insertion hole 250 is provided on the side of the bearing plate 2, and the side end of the limiting toothed ring 3 is inserted into the insertion hole 250.
[0047] Rotating the toothed handle 221 can drive the bidirectional lead screw 220 to rotate; after adjustment, insert the limiting toothed ring 3 into the insertion hole 250 so that it meshes with the toothed handle 221 and restricts the rotation of the toothed handle 221.
[0048] Specifically, the toothed throttle 221 facilitates manual adjustment of the bidirectional lead screw 220, and the engagement of the limiting toothed ring 3 with the insertion hole 250 can lock the position of the bidirectional lead screw 220, preventing external force from causing the L-shaped clamping plate 230 to loosen, and ensuring the long-term stability of the photovoltaic module 4.
[0049] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
