Description

Technical Field

[0001] This invention relates to the field of solar photovoltaic power generation technology, and in particular to a waterproof support system for photovoltaic panels. Background Technology

[0002] Solar energy is the energy produced by the continuous nuclear fusion reactions inside or on the surface of the sun, particularly in sunspots. Solar energy boasts advantages such as abundant resources, long lifespan, wide distribution, safety, cleanliness, and reliable technology. Because it can be converted into various other forms of energy, its applications are extremely broad. Obtaining electricity from solar energy requires photovoltaic conversion using solar cells.

[0003] Most existing photovoltaic (PV) systems involve first erecting a support structure, then installing PV panels on top of it. To ensure the overall waterproof integrity of the system, a continuous waterproof cover is used to press against the surface of adjacent PV panels, connecting the cover to the support structure below. This secures the PV panels and creates a complete waterproof surface between the cover and the panels. However, this creates a narrow, enclosed space between the cover, adjacent panels, and support structure. Water entering this space can easily create a "steamer effect," accelerating corrosion of the PV panels. Summary of the Invention

[0067] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0068] Example 1: like Figures 1 to 5 As shown, a first embodiment of the waterproof support system for photovoltaic panels of the present invention includes a photovoltaic panel unit 1 and a bracket 2. The bracket 2 has a drainage cavity 21, and a bearing edge 22 is bent at the upper part of the drainage cavity 21. The photovoltaic panel unit 1 is supported on the bearing edge 22 of the bracket 2 and forms a drainage barrier. A water-guiding pressure plate 4 is installed on the bracket 2 for pressing and fixing the photovoltaic panel unit 1 and for guiding rainwater to drain quickly. There is a longitudinal gap 3 between two adjacent photovoltaic panel units 1, and the longitudinal gap 3 communicates with the drainage cavity 21. When installing this waterproof support system, the brackets 2 are first erected at intervals, and then the photovoltaic panel units 1 are supported on the bearing edges 22 of adjacent brackets 2 to form a drainage barrier. Then, they are pressed and fixed by the water-guiding pressure plate 4. The water-guiding pressure plate 4 can quickly drain rainwater while fixing the photovoltaic panel unit 1, avoiding rainwater accumulation and providing good waterproof effect. Even if rainwater seeps into the longitudinal gap 3, it can be quickly drained away through the drainage cavity 21, thereby avoiding the formation of a steaming effect by rainwater residue that causes corrosion of the profile and extending the service life.

[0069] In this embodiment, the photovoltaic panel unit 1 includes a photovoltaic panel 11 and a longitudinal frame 12 and a transverse frame 13 covering the edge of the photovoltaic panel 11. A longitudinal gap 3 is formed between the longitudinal frames 12 of two adjacent photovoltaic panel units 1. The longitudinal frame 12 is supported on the bearing edge 22. The water guide plate 4 is pressed on the longitudinal frame 12 and is fastened to the bracket 2 by the anchor 5. In this structure, the longitudinal frame 12 and the transverse frame 13 surround the edge of the photovoltaic panel 11, which plays a protective role. The longitudinal frame 12 is supported on the bearing edge 22. When the two are under force, they share the force, which improves the structural strength. The water guide plate 4 is pressed on the longitudinal frame 12 and then locked and fixed by the anchor 5. Its structure is compact and the connection is stable.

[0070] In this embodiment, the drainage cavity 21 has side edges 23 bent on both sides, and a drainage groove 24 bent at the bottom of the side edges 23. A water collection groove 25 is bent on the supporting edge 22. In this structure, the water collection groove 25 can collect and discharge rainwater in the longitudinal gap 3, further avoiding the steaming effect. The drainage groove 24 can also guide and discharge the infiltrated rainwater, providing waterproof performance for the overall structure.

[0071] In this embodiment, a water guide channel 6 is provided below two adjacent horizontal frame edges 13, and the water guide channel 6 is installed between the drainage channels 24 of two adjacent supports 2. In this structure, the water guide channel 6 guides the rainwater that seeps up and down in the horizontal direction to the drainage channel 24 for discharge, ensuring the waterproof effect.

[0072] In this embodiment, a drain hole 251 is provided at the bottom of the water collection tank 25, and the longitudinal gap 3 is connected to the drainage chamber 21 through the drain hole 251. In this structure, rainwater that seeps into the longitudinal gap 3 enters the drainage chamber 21 through the drain hole 251 and is discharged.

[0073] In this embodiment, the anchor component 5 includes an anchor bolt 51 and a locking nut 52. The anchor bolt 51 passes through the water guide plate 4 and the drainage hole 251, and is then locked in place by the locking nut 52. In this structure, the anchor bolt 51 directly passes through the drainage hole 251 and is then threadedly fastened to the locking nut 51, without the need for additional punching. Specifically, the diameter of the drainage hole 251 is larger than that of the anchor bolt 51, and the anchor bolt 51 does not affect the drainage of the drainage hole 251.

[0074] In this embodiment, the water guiding pressure plate 4 has water guiding slopes 41 formed at both ends. The water guiding slopes 41 provide good water guiding effect.

[0075] In this embodiment, the waterproof support system also includes a base 7 disposed below the bracket 2, and the base 7 is fastened to the bracket 2 via a connecting component 8. Specifically, the base 7 is a purlin, which is fixed to the purlin by the bracket 2 via the connecting component 8, and the waterproof support system is installed on the roof.

[0076] In this embodiment, the connecting component 8 includes a connecting bolt 81 and a pressure block 82. One end of the pressure block 82 presses into the drainage groove 24, and the other end presses onto the base 7. The connecting bolt 81 passes through the pressure block 82 and is fastened to the base 7. In this structure, one end of the pressure block 82 presses into the drainage groove 24, and the other end presses onto the base 7. When the connecting bolt 82 is tightened, it drives the pressure block 81 to press and fix the bracket 2 onto the base 7. The operation is simple and convenient, and the connection is stable. There is no need to punch additional holes in the bracket 2 for connection and fixation, which ensures the structural strength of the bracket 2.

[0077] Example 2: like Figures 6 to 7 As shown, the second embodiment of the waterproof support system for photovoltaic panels of the present invention is basically the same as that of embodiment 1, except that: In this embodiment, a waterproof strip 10 is provided between the longitudinal frame 12 and the bearing edge 22. This structure, with the waterproof strip 10 placed in the crimping gap, further improves the waterproofing and seepage prevention effect.

[0078] In this embodiment, a recessed groove 221 for placing the waterproof adhesive strip 10 is bent on the supporting edge 22. In this structure, the recessed groove 221 facilitates the placement of the waterproof adhesive strip 10.

[0079] Example 3: like Figures 8 to 12 As shown, the third embodiment of the waterproof support system for photovoltaic panels of the present invention is basically the same as that of embodiment 1, except that: The system includes a photovoltaic panel unit 1 and a support frame 2. The support frame 2 has a drainage cavity 21, with a notch 26 formed on the upper part of the drainage cavity 21 and a bent support edge 22. The photovoltaic panel unit 1 is supported on the support edge 22 of the support frame 2, forming a drainage barrier. A water-guiding plate 4 is installed on the support frame 2 to press and fix the photovoltaic panel unit 1 and to guide rainwater for rapid discharge. There is a longitudinal gap 3 between two adjacent photovoltaic panel units 1, and the longitudinal gap 3 is connected to the drainage cavity 21 through the notch 26. In this embodiment, by forming the notch 26 on the upper part of the support frame 2, rainwater that seeps into the longitudinal gap 3 can fall directly into the drainage cavity 21 through the notch 26 for rapid discharge, avoiding the formation of a steaming effect by rainwater residue that causes corrosion of the profile, thereby extending the service life of the overall structure.

[0080] In this embodiment, the drainage cavity 21 has side edges 23 bent on both sides, and a drainage groove 24 bent at the bottom of the side edges 23. A connecting edge 27 is bent at the top of the drainage groove 24. In this structure, the drainage groove 24 can guide and discharge infiltrated rainwater, providing waterproof performance for the overall structure.

[0081] In this embodiment, the anchor component 5 includes an anchor bolt 51 and a buckle plate 53. The buckle plate 53 is located at the bottom of the bearing edge 22 and spans the notch 26. The anchor bolt 51 passes through the water guide pressure plate 4 and is fastened to the buckle plate 53. Its structure is simple and the connection is reliable.

[0082] In this embodiment, the connecting component 8 includes a connecting bolt 81, which passes through the connecting edge 27 and is fastened to the base 7. Its operation is simple and convenient, and the connection is stable.

[0083] Example 4: like Figures 13 to 17 As shown, the third embodiment of the waterproof support system for photovoltaic panels of the present invention is basically the same as that of embodiment 1, except that: The system includes a photovoltaic panel unit 1 and a support frame 2. The support frame 2 has a drainage cavity 21, with a notch 29 formed on the upper part of the drainage cavity 21 and a bent support edge 22. The photovoltaic panel unit 1 is supported on the support edge 22 of the support frame 2, forming a drainage barrier. There is a longitudinal gap 3 between two adjacent photovoltaic panel units 1. The longitudinal gap 3 is connected to the drainage cavity 21 through the notch 29. Multiple pressure plates 9 are distributed in a dotted pattern in the longitudinal gap 3 for pressing and fixing adjacent photovoltaic panel units 1. In this embodiment, by forming a notch 26 on the upper part of the support frame 2, rainwater that seeps into the longitudinal gap 3 can fall directly into the drainage cavity 21 through the notch 26 for rapid discharge, avoiding the formation of a steaming effect caused by rainwater residue and resulting in profile corrosion. Furthermore, the photovoltaic panel unit 1 is pressed and fixed on the support frame 2 by the dotted pressure plates 9, eliminating the need for a through strip cover plate, which reduces material usage and does not close the longitudinal gap 3, further avoiding the formation of a steaming effect.

[0084] In this embodiment, the anchor component 5 includes an anchor bolt 51 and a buckle plate 53. The buckle plate 53 is located at the bottom of the bearing edge 22 and spans the notch 26.

The bearing edge 22 extends into the drainage cavity 21 and is bent into a buckle edge 28. The anchor component 5 includes an anchor bolt 51 and a fastening plate 54. The fastening plate 54 is fastened to the two buckle edges 28, and the anchor bolt 51 passes through the pressure plate 9 and is fastened to the fastening plate 54. In this structure, the fastening plate 54 is fastened to the buckle edge 28, and then the anchor bolt 51 is used to lock and fix it, which drives the pressure plate 9 to press and fix the photovoltaic panel unit 1 to the bearing edge 22. Its structure is simple, the connection is firm, and it is not easy to loosen.

[0086] Example 6: like Figures 23 to 27 As shown, the fifth embodiment of the waterproof support system for photovoltaic panels of the present invention is basically the same as embodiment 3, except that: In this embodiment, a water guide channel 6 is provided below two adjacent horizontal frame 13. The water guide channel 6 is fastened between two adjacent brackets 2 and communicates with the drainage chamber 21 of the two adjacent brackets 2. Specifically, the bracket 2 has openings so that rainwater in the water guide channel 6 can be discharged into the drainage chamber 21. Its structure is simple and easy to implement.

[0087] In this embodiment, the connecting component 8 includes connecting bolts 81 and corner brackets 83. The corner brackets 83 are located on both sides of the bracket 2. The connecting bolts 81 pass through the corner brackets 83 and are fastened to the base 7.
