Description

Technical Field

[0001] This utility model relates to the field of photovoltaic panel technology, and in particular to a sealing and waterproof structure for the ridge of a double-column photovoltaic carport. Background Technology

[0002] The main principle of photovoltaic (PV) power generation is the photoelectric effect of semiconductors, which converts light energy into electrical energy. Existing PV panels are typically fixed to rooftops or other building structures using brackets, leaving them exposed to the elements all day. Therefore, rainwater easily accumulates in low-lying areas and joint gaps during rainy weather, leading to corrosion at the joints and reducing the lifespan of the PV structure. Furthermore, rainwater seeping from the bracket joint gaps in existing PV installations falls directly onto the roof, easily causing corrosion at the roof joints. Prolonged seepage can also lead to roof leaks.

[0003] The existing technology, application number 2024104507606, describes a rooftop distributed photovoltaic panel installation structure and its construction method. The existing technology has a complex structure and requires the use of several sets of pressure blocks, installation plates, connecting plates, and other structures for installation, which is time-consuming, labor-intensive, and troublesome to construct.

[0004] Therefore, it is necessary to design a waterproof sealing structure for the ridge of a double-column photovoltaic carport to solve the above problems. Utility Model Content

The main waterproof plate comprises a main board and horizontal water guide channels respectively arranged on both sides of the main board. The main board has a Z-shaped cross-section and is specifically composed of a top panel, side panels respectively arranged on both sides of the top panel, and a bottom plate respectively connected to the side panels. The side panels are perpendicular to the top panel, and the bottom plate is at an obtuse angle to the side panels.

[0008] Preferably, the photovoltaic panels are laid in a herringbone pattern on the photovoltaic panel support, the main waterproofing plate is placed in the middle of the two photovoltaic panels, and the vertical water guide channels are respectively set on the photovoltaic panel support arranged in the longitudinal row and on the outermost two sides of the photovoltaic panels.

[0009] Preferably, the vertical water guide channel is configured in an M-shape and is installed in conjunction with the photovoltaic panel via connecting fasteners.

[0010] Preferably, the transverse water guide channel includes a lower panel, vertical plates respectively disposed on both sides of the lower panel, and a baffle plate disposed on the top of the vertical plates; wherein one side of the vertical plate is perpendicular to the lower panel, and the other side of the vertical plate is disposed at an obtuse angle to the lower panel, the bottom plate of the main board is placed on the lower panel, and the side panel is attached to the obtuse angle vertical plate.

[0011] Preferably, a sealing structure is also provided between the main waterproofing plate and the photovoltaic panel.

[0012] The beneficial effects of this utility model are: This technical solution sets up a simple water guiding structure and adopts a practical combination method to directly set the main waterproof plate on the horizontal water guiding groove.

[0019] Reference Figures 1 to 5A waterproof sealing structure for the ridge of a double-column photovoltaic carport includes a steel main frame 1, several groups of photovoltaic panels 2 evenly laid on the photovoltaic panel support, a vertical water guide channel 3 laid between the longitudinal rows of photovoltaic panels, and a main waterproof plate 4 placed in the middle of the photovoltaic panel support and horizontally arranged in the middle of the photovoltaic panels.

[0020] The photovoltaic panels are laid in a herringbone pattern on the photovoltaic panel support. The main waterproof board is placed in the middle of the two photovoltaic panels. The vertical water guide channels are respectively set on the photovoltaic panel support arranged in the longitudinal row and are located on the outermost two sides of the photovoltaic panels.

[0021] The vertical guide water channel 3 is configured in an M-shape and is installed in conjunction with the photovoltaic panel through connecting fasteners.

[0022] The main waterproof plate 4 includes a main plate 41 and transverse water guide grooves 42 respectively disposed on both sides of the main plate;

[0023] The main board 41 has a Z-shaped cross-section. Specifically, it consists of a top panel 411, side panels 412 respectively disposed on both sides of the top panel, and a bottom plate 413 respectively connected to the side panels. The side panels 412 are perpendicular to the top panel 411, and the bottom plate 413 is set at an obtuse angle to the side panels 412, which is more than 90°, to facilitate the inclined flow of water. The specific angle is determined according to the tilt angle of the photovoltaic panel.

[0024] The horizontal water guide channel 42 includes a lower panel 421, vertical plates 422 respectively disposed on both sides of the lower panel, and a water baffle 423 disposed on the top of the vertical plates. The vertical plate on one side is perpendicular to the lower panel, and the vertical plate on the other side is set at an obtuse angle to the lower panel. The vertically disposed vertical plate mainly serves to block water, while the obtusely disposed vertical plate is designed to facilitate installation with the main board 41. The angles of the two are similar, which facilitates installation. The water baffles 423 disposed on both sides extend in the same direction. The water baffle 423 on the side of the vertical plate that is perpendicular to the lower panel is mainly used to prevent water from overflowing due to excessive flow or rainwater from splashing out. It also serves to assist the photovoltaic panel in preventing water from overflowing and provides support.

[0025] In the specific installation, the base plate 413 on one side of the motherboard 41 is placed on the lower panel 421, and the side panel 412 on this side is attached to the vertical plate 422 with an obtuse angle; in fact, the two sides of the motherboard are pressed onto the horizontal water guide groove 42.

[0026] In the first implementation case, during installation, a horizontal water guide channel is first placed according to the width of the photovoltaic panel and installed in the gap between the photovoltaic panels. Then, the main waterproof plate is placed, and a vertical water guide channel 3 is placed between the photovoltaic panels, with one end of the vertical water guide channel 3 connected to one end of the horizontal water guide channel. Finally, the photovoltaic panels are placed on one side of the horizontal water guide channel and fixed in place using fasteners in conjunction with the vertical water guide channel 3. When there is water, it flows in along the main waterproof plate and into the gap between the photovoltaic panels. Finally, silicone strips are inserted. The silicone strips are recommended but not essential; waterproofing is possible even without silicone strips. The water flows in and out of the horizontal water guide channel, then flows from the port into the vertical water guide channel 3.

[0027] The second implementation case is to lay the equipment according to the implementation case 1, and place the silicone strip 43 or other sealing components between the main waterproof plate and the photovoltaic panel. Since more water will flow directly out through the photovoltaic panel after the silicone strip is placed, instead of rainwater being collected through the horizontal water channel and then flowing out through the vertical M-shaped water channel, this method is more convenient and faster.

[0028] The advantages of this utility model are that, by setting a simple water guiding structure and adopting a practical combination method, the main waterproof plate is directly placed on the horizontal water guiding groove. Water flow is achieved through the pressing of the photovoltaic panel itself. The product has a simple structure, is easy to manufacture, has low cost, and can be installed quickly, thereby saving time and improving efficiency.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
