[0002] Photovoltaic support systems are widely used in distributed photovoltaic (PV) power generation systems, serving as crucial components for a reliable connection between the roof and PV modules. Currently, PV support structures vary widely depending on the PV modules and rooftops used. Since PV modules are installed outdoors, drainage during rain is particularly important.

[0003] Existing photovoltaic support structures are unstable. For example, a photovoltaic waterproof support with Chinese utility model patent application number CN202021840695.1 uses clamps. The clamps are fitted on the outside of the longitudinal water tank and fixedly connected to the support frame to fix the longitudinal water tank. The clamps are only set at the intersection of the transverse and longitudinal water tanks to fix the transverse and longitudinal water tanks and photovoltaic panels. The number of clamps is small, and the clamp structure is simple and unstable, which cannot fix the transverse and longitudinal water tanks and photovoltaic panels well. Utility Model Content

[0034] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the embodiments of this disclosure will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the embodiments of this disclosure and are not intended to limit the embodiments of this disclosure.

[0035] like Figure 1 As shown, one embodiment of this disclosure proposes a photovoltaic waterproof bracket, which includes: an M-shaped main waterproof bracket 100, used to be installed above a crossbeam 140 and below a photovoltaic module 600, the central area of ​​the M-shaped main waterproof bracket 100 being a water-guiding groove 120; a crossbeam 200, installed on the M-shaped main waterproof bracket 100, specifically, the crossbeam 200 is fastened to the M-shaped main waterproof bracket 100 by bolts; and a pressure block 300, the pressure block 300 being fastened to the side of the photovoltaic module 600 and the crossbeam 200 by bolts.

[0036] In this embodiment, multiple crossarms and pressure blocks are provided along the length of the M-shaped main waterproof bracket. Tightening the bolts drives the pressure blocks to move towards the crossarms, thereby securing the edges of the photovoltaic modules by bringing the pressure blocks and crossarms closer together. The M-shaped main waterproof bracket of this embodiment serves both as a water guide and a fixation point for the photovoltaic modules. Furthermore, the M-shaped structure improves structural stability and load-bearing capacity, and provides good bending and torsional resistance.

[0037] like Figure 2 As shown, the photovoltaic waterproof bracket also includes a U-shaped water guide channel 500, which spans between two adjacent M-shaped main waterproof brackets 100, with both ends of the U-shaped water guide channel 500 located above the water guide groove 120; the U-shaped water guide channel 500 is used to set the mounting frame of the photovoltaic module 600.

[0038] In this embodiment of the present disclosure, two adjacent photovoltaic module mounting frames are provided within the U-shaped water guide channel. The two ends of the longitudinal U-shaped water guide channel are respectively mounted on the transverse M-shaped main waterproof support. The port of the longitudinal U-shaped water guide channel is located above the water guide groove in the central area of ​​the M-shaped main waterproof support. The port of the longitudinal U-shaped water guide channel has a water guide slope facing the water guide groove. Figure 3 As shown, two adjacent photovoltaic module mounting frames are set inside a U-shaped water guide channel, and the two mounting frames are connected by waterproof adhesive 610. If there is leakage between the two mounting frames, the water will enter the U-shaped water guide channel.

[0039] like Figure 4 and Figure 5 As shown, the specific structure of the M-type main waterproof bracket includes: two upper edge support surfaces 110 for supporting the U-shaped water guide channel 500; a central area water guide groove 120 located between the two upper edge support surfaces 110, the bottom surface of the central area water guide groove 120 being horizontal and also used for mounting on the crossbeam 140; and two outer support legs 130, the ends of which have outwardly folded flanges, the flanges being flush with the bottom surface of the central area water guide channel and used for fixing to the crossbeam 140.

[0040] The water-guiding groove of the M-type main waterproof bracket in this embodiment is used for drainage, and it can be directly fixed to the crossbeam by screws 150 through the flange, making the M-type main waterproof bracket more stable. Figure 4 As shown, when the length of the M-type main waterproof bracket is insufficient, it can be spliced ​​using screws of size 160.

[0041] like Figure 1 and Figure 6 As shown, the crossbeam 200 has downwardly bent fastening portions 210 at both ends, which fasten to the upper support surface 110 of the M-shaped main waterproof bracket 100; the fastening portions 210 of the crossbeam 200 are fastened to the side wall of the outer support leg 130 of the M-shaped main waterproof bracket 100 by bolts. A through hole is provided in the central area of ​​the crossbeam 200.

[0042] The crossarm of this embodiment can be fastened to the two upper support surfaces and spanned between the two outer support legs. The width and shape of the crossarm can be set according to actual conditions, and the crossarm can be made of aluminum alloy.

[0043] like Figure 1 and Figure 6As shown, the pressure block includes: a central pressure block 310, the central pressure block 310 having a groove in its central region, the groove having a first through hole in its central region, the first through hole being fastened to the through hole by bolts; and / or; a side pressure block 320, the side pressure block 320 having two sequentially connected first bending structures 321 and second bending structures 322, the transverse plane of the first bending structure 321 being used to snap onto the upper surface of the photovoltaic module; the transverse plane of the second bending structure 322 having a second through hole in its central region, the second through hole being fastened to the through hole by bolts.

[0044] In other words, the pressure block has two structures depending on its location: a central pressure block and a side pressure block, both of which can be made of aluminum alloy. Multiple central and side pressure blocks are respectively installed along the corresponding M-shaped main waterproof bracket.

[0045] Specifically, the medium pressure block 310 is used to be disposed between two adjacent photovoltaic modules 600; the end of the groove has a counter that flips outward, and the two counters are respectively used to engage with the surfaces of the two adjacent photovoltaic modules 600.

[0046] In other words, a medium pressure block is used between the edges of two adjacent photovoltaic modules and the M-type main waterproof bracket. The M-type main waterproof bracket and photovoltaic modules on both sides are secured by tightening the bolts between the medium pressure block and the crossarm.

[0047] The side pressure block 320 is used to be installed on the M-shaped main waterproof bracket 100 with a photovoltaic module 600 on one side; the horizontal structure of the first bending structure 321 of the side pressure block 320 is used to snap onto the surface of the photovoltaic module 600, and the end of the vertical structure of the second bending structure 322 of the side pressure block 320 is set on the crossbeam 200.

[0048] In other words, the edge pressure block is set on the M-type main waterproof bracket with photovoltaic modules on only one side. Such an M-type main waterproof bracket is usually located on the outermost side. At this time, the edge pressure block is used to tighten the photovoltaic modules and the M-type main waterproof bracket on one side by tightening the bolts between the edge pressure block and the crossarm.

[0049] like Figure 1 As shown, the photovoltaic waterproof bracket further includes: a cover plate 400, which covers the intermediate pressure block 310. The cover plate 400 has an installation sleeve in the central area facing the groove. The central area of ​​the installation sleeve has an installation cavity. The installation sleeve is located in the groove of the intermediate pressure block 310, and the installation cavity is fitted outside the bolt.

[0050] The cover plate is placed on the middle pressure block to prevent water from entering the groove.

[0051] like Figure 7As shown, another embodiment of this disclosure provides a distributed residential photovoltaic power generation system, including: a photovoltaic waterproof bracket and photovoltaic modules as described above. Multiple M-shaped main waterproof brackets 100 and U-shaped water guide channels 500 are provided. The M-shaped main waterproof brackets 100 are spaced apart on both sides of a ridge maintenance board 800, and their ends are respectively used to connect the ridge maintenance board and the gutter. The horizontally arranged M-shaped main waterproof brackets 100 and the vertically arranged U-shaped water guide channels 500 form a grid, and the photovoltaic modules 600 are arranged within the grid. Each photovoltaic module includes a photovoltaic panel and mounting frames disposed around its perimeter. The vertically arranged mounting frames on both sides of the photovoltaic module are respectively disposed within corresponding U-shaped water guide channels 500. At least two pressure blocks 300 are provided on both sides of the photovoltaic panel in the horizontal direction, and the pressure blocks 300 and corresponding crossbeams 200 fix the edges of the photovoltaic panel to the M-shaped main waterproof brackets 100.

In this embodiment, multiple horizontal M-shaped main waterproof supports and multiple vertical U-shaped drainage channels intersect perpendicularly to form a grid on both sides of the ridge maintenance board, with photovoltaic modules installed within the grid. The mounting frames on both sides of the photovoltaic modules are located within the U-shaped drainage channels 500, and the mounting frames on both sides of the vertical channels are screwed onto the M-shaped main waterproof supports. Water drainage from the photovoltaic modules enters the M-shaped main waterproof supports and flows into the gutters for discharge. Figure 7 and Figure 8 As shown, multiple longitudinal U-shaped drainage channels are installed on both sides of the ridge maintenance panel along its width. One side of the longitudinal U-shaped drainage channel is located below one side of the ridge maintenance panel to collect drainage from the ridge maintenance panel. The other side of the longitudinal U-shaped drainage channel has a photovoltaic module mounting frame. The remaining longitudinal U-shaped drainage channels each have two adjacent photovoltaic module mounting frames (details omitted). The two ends of the longitudinal U-shaped drainage channels are located above the transverse M-shaped main waterproofing bracket, facilitating the collection of drainage from the longitudinal U-shaped drainage channels. Multiple photovoltaic module edges are supported on both sides of the transverse M-shaped main waterproofing bracket along its length to collect drainage from the photovoltaic modules. Each photovoltaic module has two pressure blocks along its edge to secure it to the M-shaped main waterproofing bracket. The two ends of the transverse M-shaped main waterproofing bracket connect to the area below the ridge maintenance panel and the area above the gutter, respectively, draining the collected drainage from the photovoltaic modules and the ridge maintenance panel into the gutter.
