Abstract
Description
Technical Field
[0001] This utility model relates to the field of photovoltaic panel technology, specifically to a novel waterproof photovoltaic panel. Background Technology
[0002] In traditional waterproof photovoltaic panel systems, there is a large vertical gap between the photovoltaic module frame and the connecting bracket. During strong winds and heavy rain, wind and rain can easily penetrate through this gap, causing the entire system to fail in its waterproofing.
[0003] For example, in the Chinese invention patent with publication number CN119362973A and patent name "Waterproof Photovoltaic Panel Support System", it is specifically disclosed that the system includes a photovoltaic panel unit, a bracket, a pressure foot, and a water-guiding plate. The bracket has a drainage cavity, and the upper part of the drainage cavity is formed with a notch and a bent support part. The photovoltaic panel unit is supported on the support part and forms a drainage barrier. There is a longitudinal gap between two adjacent photovoltaic panel units. The longitudinal gap is connected to the drainage cavity through the notch. A connecting part is formed on the bracket. The water-guiding plate is pressed on two adjacent photovoltaic panel units and locked to the connecting part through the pressure foot.
[0004] However, although the waterproof support system in the above scheme drains water through the drainage chamber of the bracket, its drainage barrier only relies on the photovoltaic panel unit to cover the load-bearing part. It does not solve the problem of vertical gaps between the component frame and the bracket. Wind and rain may still enter through the gaps. It lacks an effective vertical sealing and directional drainage structure, cannot block the wind and rain penetration path, and the seepage water is easy to accumulate inside the system.
[0005] Therefore, a novel waterproof photovoltaic panel is proposed to address the aforementioned problems. Utility Model Content

[0038] The present invention will be further described below with reference to the embodiments.
[0039] Example:
[0040] This case proposes a novel waterproof photovoltaic panel, see attached document. Figure 1-8 It mainly includes at least two parallel supports 1, and the structure shown in this embodiment is three supports 1.
[0041] A concave-shaped water guide channel 2 is placed horizontally between the connected brackets 1. Three water guide channels 2 are respectively provided between adjacent brackets 1. The three brackets 1 and several water guide channels 2 form a grid-shaped bracket structure. A rectangular frame structure 3 composed of two component long frame 31 and two component short frame 32 is set on the adjacent brackets 1. That is, a rectangular frame structure 3 for assembling photovoltaic panels is set in each of the four opening spaces in the grid-shaped bracket structure.
[0042] It should be noted that the frame structure 3 is provided with a recess 30 for assembling the photovoltaic panel 4. The cross-section of the long frame 31 and the short frame 32 of the module includes a U-shaped space, with a right-angle pressure plate vertically provided on one side of its upper end. The recess 30 is located at the recess of the right-angle pressure plate. It should be noted that the top of the right-angle pressure plate has a certain degree of elasticity and its top is tilted downwards, which can provide a certain pressure on the photovoltaic panel inserted into the recess 30 to prevent the photovoltaic panel from loosening. This structure is a known technology and will not be described in detail here.
[0043] The cross-section of the bracket 1 is shaped like a "Z". Two drainage grooves 11 are formed in the recesses on both sides of the bracket 1. A waterproof cover plate 5 is provided at the upper end of the short frame 3 of the component. Specifically, the two long frames 31 of the components in the adjacent frame structure 3 are symmetrical to each other, and the adjacent short frames 32 of the components are similar. The cross-section of the waterproof cover plate 5 is in the shape of an isosceles trapezoid, with inclined surfaces on both sides that can guide rainwater. The inclined surfaces are inclined towards the drainage groove 11 and / or the water guide groove 2.
[0044] Specifically, the waterproof cover plate 5 has several rivets spaced apart along the extension direction of the plate body in the middle. The rivets penetrate the plate body and are detachably mounted on the top of the bracket 1 with the rivets facing downwards.
[0045] Waterproof strips 6 are provided between the waterproof cover plate 5 and the long frame 31 and / or the short frame 3 of the component. The waterproof strips 6 extend in the same direction as the long frame 31 and / or the short frame 3 of the component, which further improves the waterproof effect of the frame structure 3.
[0046] Meanwhile, in order to allow rainwater on the waterproof cover plate 5 in the frame structure 3 to be smoothly discharged to the drainage channel 11 and / or the water guide channel 2, in this embodiment, the lower edge width of the component long frame 31 and / or the component short frame 3 is smaller than the inner width of the drainage channel 11 and / or the water guide channel 2. Thus, under the action of the inclined surface of the waterproof cover plate 5, the rainwater will be smoothly guided into the drainage channel 11 and / or the water guide channel 2.
[0047] To facilitate the flow of water from the horizontal water guide channel 2 to the drainage channel 11, an opening 33 is provided between the adjacent long frame 31 and short frame 32 of the component, as shown in the attached figure. Figure 7 As shown, the connection between the long border 31 and the short border 32 of the component is achieved.
[0048] The vertical photovoltaic module frame is pressed onto the bracket 1 by a vertical waterproof cover plate 5 and a waterproof strip 6, with no gaps between them, to prevent wind from blowing rainwater directly into the gaps.
[0049] However, in most existing technologies, there are vertical gaps between the component frames and the supports, allowing wind and rain to still seep in through these openings, as shown in the attached image. Figure 8 - Appendix Figure 9 As shown, the gap is attached. Figure 9 As shown in the shaded area.
[0050] The drainage channel 11 on the shaped bracket 1 can drain away rainwater that seeps in from the gaps, preventing rainwater from entering the bottom of the entire photovoltaic BIPV system.
[0051] In the horizontal direction, the adjacent short frame 32 of the photovoltaic module is also equipped with a waterproof cover plate 5 and a waterproof strip 6, which can drain away most of the rainwater.
[0052] The horizontal water channel 2 below can catch the water seepage from the waterproof cover plate 5 and guide the seepage into the drainage channel 11 on the bracket 1 to drain away.
[0053] It is worth noting that in this embodiment, the photovoltaic panel bracket is connected to other bracket bodies through purlins 7. The assembly position is selected according to the actual application scenario, such as support base, wall, and other structures. In order to avoid directly drilling holes in the panel body, this embodiment connects to the mounting surface through purlins 7 that are detachably set on the bracket 1.
[0054] The purlin 7 is detachably mounted on the bracket 1 via a presser foot 72. The presser foot 72 includes a bent surface that can fit onto an adjacent bracket 1. In this embodiment, the presser foot 72 and the purlin 7 can be assembled in two ways. In the first way, the purlin 7 is directly connected to the presser foot 72 via screws 71. The presser foot 72 has holes corresponding to the screws 71, as shown in the attached figure. Figure 5 As shown.
[0055] The second method involves fixing the pressure foot 72 to the purlin 7 with bolts, as shown in the attached diagram. Figure 2-4 As shown.
[0056] Drainage channels 11 are pre-formed in the recesses on both sides of the bracket 1, and concave water guide channels 2 are horizontally overlapped between adjacent brackets 1. The two ends of the water guide channels 2 are connected to the drainage channels 11 of the bracket.
[0057] The short frame 32 of the component in the rectangular frame structure 3 is overlapped between the adjacent brackets 1, and the recess 30 in the frame structure 3 is embedded in the photovoltaic panel 4 and pressed by the detachable sloping waterproof cover plate 5.
[0058] A waterproof sealant strip 6 is embedded between the waterproof cover plate 5 and the frame structure 3 to form a vertical seal. The slope of the waterproof cover plate 5 is inclined toward the water guide channel 2 to ensure that rainwater is guided to the water guide channel 2.
[0059] An opening 33 is reserved at the joint between the long frame 31 and the short frame 32 of the component, and the two sides of the waterproof cover plate 5 are inclined so that the seepage water falls directly into the lower water guide channel 2.
[0060] The water guide channel 2 directs the collected water into the main drainage channel 11 of the bracket, and finally discharges it from the side of the system. The purlin 7 is fixed to the bracket 1 by Z-shaped connectors 72 or screws 71, allowing for fine-tuning of the position to accommodate installation errors.
[0061] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
