Description

Technical Field

[0001] This utility model relates to the technical field of photovoltaic support structures, and in particular to a waterproof support suitable for installing photovoltaic modules on trapezoidal color steel tile roofs. Background Technology

[0002] With the rapid development of distributed photovoltaic (PV) power generation systems, rooftop PV projects have become increasingly popular due to their lack of additional land use and the ability to directly install PV modules on building rooftops. These systems generate and utilize electricity locally by fixing PV panels and their supports to the building roof, reducing reliance on grid transmission systems and thus finding widespread application in buildings of all sizes.

[0003] Currently, corrugated steel sheets are a widely used roofing material in many types of building structures, such as industrial plants and residential buildings. With their unique plate-like structure, corrugated steel sheets are typically formed through stamping or rolling processes into a series of strip-shaped protrusions with specific cross-sectional shapes (such as trapezoids, triangles, or rectangles), thereby enhancing the material's strength and durability.

[0004] However, existing mounting brackets for fixing photovoltaic panels face some challenges when applied to corrugated steel roofs:

[0005] Specifically, the existing photovoltaic installation frame is not well-suited to the surface of the corrugated steel sheet, which may require drilling or other modifications to the corrugated steel sheet during installation. This not only damages the original structural integrity of the roof but may also lead to maintenance problems such as water leakage.

[0006] Therefore, there is an urgent need for a technical solution that can effectively solve the above problems and improve the stability and waterproof performance of photovoltaic panels during the installation process on corrugated steel roofs.

[0007] In view of this, the inventor has designed a waterproof bracket specifically for the installation of photovoltaic modules on trapezoidal color steel tile roofs, which leads to this invention. Summary of the Invention

[0019] Preferably, the second locking hole is an elongated kidney-shaped hole, and the extending direction of the second locking hole is distributed along the length direction of the connecting segment.

[0020] Preferably, the water tank fixing member is in a "C" shape with an open bottom and includes second side walls arranged vertically and in parallel on both sides and a support wall connected between the tops of the two second side walls. The top surface of the support wall forms the lower pressing surface. The bottoms of the two second side walls extend integrally in a direction away from each other to form a connecting edge. A third locking hole for locking and cooperating with the support track is provided on the connecting edge. A V-shaped limiting portion is symmetrically provided between the support wall and the two second side walls on both sides. The opening of the limiting portion faces upward so that a limiting area is formed by enclosing between its side walls and the second side walls. The two side walls of the main water tank are limited and fixed in the limiting area.

[0021] Preferably, continuous convex second reinforcing ribs are provided between the support wall and the limiting portions on both sides.

Detailed Implementation

[0047] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0048] As prior art of this utility model, the general form of a 700 color steel tile roof is that an integral strip-shaped protrusion 710 is formed on a flat roof surface by stamping or rolling. The strip-shaped protrusion 710 is generally in the shape of an isosceles trapezoid with a cross-section, which serves as the installation base for the waterproof bracket. The specific structure of the waterproof bracket is described below through an embodiment:

[0049] Please see Figures 1 to 11 This is a waterproof bracket for installing photovoltaic modules on trapezoidal color steel tile roofs, which is the preferred embodiment of the present utility model. It includes a connecting clamp 100, a support rail 200, a main water tank 300, a water tank fixing component 400, and a pressing component 500, as detailed below:

[0050] like Figure 3 , 5 As shown in Figure 6, the connecting clamp 100 is provided with at least one set, including a locking member 110 that is adapted to the shape of the strip protrusion 710 of the color steel tile 700 roof and can be detachably fixed, and a connecting shaft 120 protruding from the upper end of the locking member 110.

[0051] Specifically, in this embodiment, the locking member 110 has a trapezoidal cross-section and includes a bottom wall 111 horizontally distributed at the top and first side walls 112 extending symmetrically and obliquely downward along both sides of the bottom wall 111. The two first side walls 112 and the bottom wall 111 enclose each other to form a downward-opening mounting groove 113. The shape of the mounting groove 113 is adapted to the cross-sectional shape of the strip protrusion 710 of the color steel tile 700, so that the locking member 110 can fit perfectly on the strip protrusion 710, which facilitates locking and fixing.

[0052] Furthermore, in this embodiment, the connecting shaft 120 is integrally fixed to the upper end face of the bottom wall 111, the bottom wall 111 is attached to the upper end face of the trapezoidal strip protrusion 710 of the color steel tile 700, and the two first side walls 112 are respectively attached to the two side walls of the strip protrusion 710.

[0053] like Figure 6 As shown, a first locking hole 114 is provided through the first side wall 112. The first locking hole 114 is locked and fixed to the strip-shaped protrusion 710 of the color steel tile 700 by a self-tapping screw. In this embodiment, after the self-tapping screw passes through the first locking hole 114, it is locked into the side wall of the strip-shaped protrusion 710 of the color steel tile 700, and glue is applied inside to improve the connection strength and sealing effect.

[0054] like Figure 6 Specifically, the bottom wall 111 and the first side walls 112 on both sides are provided with continuously distributed protruding first reinforcing ribs 115. The protruding direction of the first reinforcing ribs 115 is towards the direction away from the opening of the mounting groove 113, thereby strengthening the overall structural strength of the locking member 110 through the first reinforcing ribs 115, making the connection between the waterproof bracket and the color steel tile 700 roof more stable.

[0055] like Figure 4 , 5 As shown in Figure 6, the support rail 200 is linear and detachably disposed between adjacent connecting shafts 120. In this embodiment, the connecting shaft 120 is a threaded rod with two symmetrically arranged on both sides of the upper end face of the same bottom wall 111. The support rail 200 is shaped like a downward-opening "U", and the bottom of its two side walls extends horizontally in a mutually distancing direction to form two connecting segments 210. The two connecting segments 210 are plate-shaped, and both ends of their length are symmetrically provided with second locking holes 211 that are opposite to the position of the connecting shaft 120. The support rail 200 is fixed to the bottom wall 111 by threaded engagement with the connecting shaft 120 through a first nut (not shown in the figure). The distance between the two connecting shafts 120 on the same locking member 110 is adapted to the distance between the two second locking holes 211 that are opposite to the position on the adjacent connecting segments 210.

[0056] Specifically, the second locking hole 211 is an elongated waist-shaped hole, and the extension direction of the second locking hole 211 is distributed along the length direction of the connecting section 210.

[0057] Therefore, after the connecting clamps 100 on both sides are locked and fixed to the two trapezoidal strip protrusions 710 respectively, the support rail 200 is placed horizontally between the two connecting clamps 100 in a position perpendicular to the strip protrusions 710. The two second locking holes 211 on the same side of the support rail 200 are respectively aligned with the two connecting shafts 120 at the upper end of the corresponding locking member 110. Then the support rail 200 is lowered so that the two connecting shafts 120 pass through the two second locking holes 211 respectively. Finally, the corresponding first nut is locked in to lock and fix this side of the support rail 200 to the upper end of the aforementioned locking member 110. The above operation is repeated to lock and fix the other side of the support rail 200 to the upper end of another locking member 110, thereby forming a stable installation base between the two strip protrusions 710, which facilitates the subsequent installation and fixing of the photovoltaic module 600 and the main water tank 300.

[0058] The elongated, waist-shaped hole allows for easy adjustment of the support rail 200's position according to the actual installation location, thus accommodating installation position errors within a certain range.

[0059] like Figure 4 , 5 As shown, the main water tank 300 is linear and is placed vertically on the upper end of the support rail 200. In this embodiment, the main water tank 300 is U-shaped with the opening facing upward, and the two sides of the main water tank 300 form inclined outward extending tank walls 310, thereby forming a linear extending water guiding channel 320 in the middle of the main water tank 300, which facilitates the guiding of water flow between adjacent photovoltaic modules 600.

[0060] like Figure 5 , 7 As shown, the water tank fixing member 400 has a clamping structure for clamping and fixing the main water tank 300 to the upper end of the support rail 200 and a lower clamping surface located above the main water tank 300 (not shown in the figure).

[0061] In this embodiment, the water tank fixing member 400 is in the shape of an "U" with the opening facing downward, and includes a second side wall 410 arranged vertically and parallel to both sides and a support wall 420 connecting the tops of the two second side walls 410. The top surface of the support wall 420 forms a downward pressing surface (not shown in the figure). The bottoms of the two second side walls 410 extend integrally in a direction away from each other to form a sheet-like connecting edge 430. The connecting edge 430 is provided with a third locking hole 431 that locks into the support rail 200.

[0062] Specifically, there are two third locking holes 431, symmetrically distributed on both sides of the connecting edge 430. When locking the water tank fixing component 400, simply move the connecting edge 430 to any position on the upper surface of the support rail 200, and then use the corresponding self-tapping screws and nuts to lock the two connecting edges 430 on the end face of the support rail 200. This allows the water tank fixing component 400 to be fixed at any position on the support rail 200. The water tank fixing components 400 between adjacent support rails 200 continue to cooperate to fix the two side edges of the photovoltaic module 600 frame, thereby finally locking the photovoltaic module 600 onto the upper end of the color steel tile 700 roof.

[0063] Furthermore, a V-shaped limiting part 440 is symmetrically provided between the support wall 420 and the second side walls 410 on both sides. The opening of the limiting part 440 faces upward so that its side wall and the second side wall 410 enclose and form a limiting area 441. The two side walls of the main water tank 300 are limited and fixed within the limiting area 441.

[0064] Specifically, in this embodiment, the walls 310 on both sides of the main water tank 300 extend obliquely into the limiting area 441. When installing the main water tank 300, it is first placed horizontally between two adjacent and parallel supporting rails 200 in a direction perpendicular to the supporting rail 200. At this time, the main water tank 300 and the strip-shaped protrusions 710 of the color steel tile 700 are distributed in parallel. Then, the water tank fixing member 400 is pressed in from above the main water tank 300, so that the walls 310 on both sides are correspondingly inserted into the limiting area 441. After the connecting edges 430 on both sides of the water tank fixing member 400 are locked and fixed to the upper end face of the supporting rail 200, the position of the main water tank 300 on that side is pressed and fixed. Repeat the above process to lock and fix the other side of the main water tank 300 to another supporting rail 200, thereby completing the installation and fixing of the main water tank 300. At this time, the upper end of the water tank fixing member 400 forms a lower pressing surface, which serves as the installation foundation for the subsequent support and fixing of the photovoltaic module 600.

[0065] Furthermore, a series of raised second reinforcing ribs 450 are provided between the support wall 420 and the limiting parts 440 on both sides. The protruding direction of the second reinforcing ribs 450 is towards the opening direction of the water tank fixing member 400, thereby strengthening the overall structural strength of the water tank fixing member 400 through the second reinforcing ribs 450, making the connection between the main water tank 300 and the support track 200 more stable.

[0066] like Figure 7 , 8 As shown in Figure 9, the clamping component 500 is located at the upper end of the lower clamping surface and has an upper clamping surface that can be adjusted up and down (not shown in the figure), which is used to cooperate with the lower clamping surface to clamp and fix the frame 610 of the photovoltaic module 600.

[0067] Specifically, in this embodiment, the clamping assembly 500 includes an edge clamping member 510 for locking and fixing the edge of the photovoltaic module 600 and a middle clamping member 520 for fixing adjacent photovoltaic modules 600, as detailed below:

[0068] like Figure 7 As shown, the edge pressing member 510 includes a first pressing plate 511 that is bent in an L-shape, a third side wall 512, and a first locking bolt 513 that penetrates vertically through the first pressing plate 511. A fourth locking hole 421 that is locked and engaged with the first locking bolt 513 is provided on the lower pressing surface (i.e., the support wall 420). The lower end surface of the first pressing plate 511 forms an upper pressing surface (not shown in the figure). The upper pressing surface, the third side wall 512, and the lower pressing surface enclose a pressing space 515 for the frame 610 of the photovoltaic bracket to pass through.

[0069] The third sidewall 512 is integrally bent along the edge of the first pressure plate 511, and the two sides of the third sidewall 512 continue to be bent vertically towards the direction close to the first pressure plate 511 to form a bending edge 514. The two bending edges 514 and the third sidewall 512 enclose a clearance area (not shown in the figure). The first locking bolt 513 penetrates the first pressure plate 511 vertically along the clearance area. The pressing space 515 is located adjacent to the clearance area. After the frame 610 of the photovoltaic module 600 is pressed into the pressing space 515, it is in close contact with the edge of the bending edge 514.

[0070] The clearance area formed by the bending edge 514 allows for clearance of the first locking bolt 513, preventing interference between the first locking bolt 513 and the frame 610 of the photovoltaic module 600 pressed into the clamping space 515, thereby facilitating the clamping and fixing of the edge of the photovoltaic module 600.

[0071] The process of fixing the edge of the photovoltaic module 600 is as follows: The frame 610 of the photovoltaic module 600 is overlapped with the upper end face (i.e., the lower pressing surface) of the water tank fixing member 400. Then, the first pressing plate 511 and the third side wall 512 of the edge pressing member 510 are integrally placed on the edge of the frame 610, so that the lower end face (i.e., the upper pressing surface) of the first pressing plate 511 is in contact with the upper end face of the frame 610, and the edge of the bent edge 514 is in contact with the side wall of the edge. Then, the first locking bolt 513 is inserted, with its lower end passing through the fourth locking hole 421. Finally, the portion of the first locking bolt 513 passing through the fourth locking hole 421 is locked with the corresponding nut, pressing and fixing the upper and lower end faces of the frame 610 of the photovoltaic module 600, thus finally and stably fixing it to the upper end of the water tank fixing member 400 at that position. Repeating the above process, other positions on the same side of the frame 610 of the photovoltaic module 600 can be pressed and fixed to other water tank fixing members 400 at corresponding positions.

[0072] like Figure 8 , 9As shown, the intermediate pressure component 520 includes a sheet-shaped second pressure plate 521 and a second locking bolt 522 that vertically penetrates the second pressure plate 521. A fourth locking hole 421 that engages with the first locking bolt 513 is provided through the lower pressure surface. The lower end surface of the second pressure plate 521 forms an upper pressure surface (not shown in the figure). The upper pressure surface and the lower pressure surface enclose a pressure space 515 located on both sides of the second locking bolt 522 for the frame 610 of the adjacent photovoltaic bracket to pass through.

[0073] Specifically, in this embodiment, the second pressure plate 521 is square-shaped, the second locking bolt 522 penetrates the second pressure plate 521 vertically along its center, and the bottom of the second locking bolt 522 is engaged with the corresponding nut.

[0074] The process of fixing adjacent photovoltaic modules 600 is as follows: the frames 610 of adjacent photovoltaic modules 600 are simultaneously overlapped on the upper surface of the water tank fixing member 400, so that the frames 610 of photovoltaic modules 600 are symmetrically distributed with the fourth locking hole 421 as the boundary. Then, the second pressure plate 521 is placed on the upper side of the frames 610 of the two photovoltaic modules 600, so that the hole in the center of the second pressure plate 521 for passing through the second locking bolt 522 is aligned with the fourth locking hole 421. Finally, the fourth locking bolt is inserted, so that it passes through the second pressure plate 521 and the fourth locking hole 421 at the upper end of the water tank fixing member 400 in one go. After connecting the corresponding nuts, the frames 610 of adjacent photovoltaic modules 600 are pressed and fixed on both sides of the intermediate pressure member 520.

[0075] Preferred, such as Figure 10 As shown, a dustproof strip 800 is provided between adjacent support rails 200 to cover the installation gap between adjacent photovoltaic panels.

[0076] Specifically, in this embodiment, the dustproof strip 800 is long and flat, and the middle of the dustproof strip 800 is recessed downward to form a V-shaped limiting groove 810. The limiting groove 810 extends along the length of the dustproof strip 800. The second pressure plate 521 has symmetrically arranged positioning parts that extend downward and engage with the limiting groove 810. The cross-sectional shape of the positioning parts is adapted to the limiting groove 810. Thus, the dustproof strip 800 can be installed along the gap between adjacent photovoltaic modules 600. Through the mutual cooperation between the positioning parts and the limiting groove 810, the dustproof strip 800 is limited, thereby sealing the gap between adjacent photovoltaic modules 600 and preventing dust from entering the interior of the photovoltaic module 600.

[0077] In addition, such as Figure 11As shown, it also includes a channel plate 900, which can replace the photovoltaic module 600 and is installed and fixed between adjacent water tank fixing parts 400. It is closely distributed with the photovoltaic module 600, thereby forming a channel for maintenance personnel to walk between adjacent photovoltaic modules 600. Its edges are pressed and fixed by the middle pressure part 520 and the side pressure part 510 (not shown in the figure).

[0078] In particular, the surface of the passage plate 900 is also provided with several cylindrical anti-slip protrusions 910, thereby increasing friction and preventing maintenance personnel from slipping when walking.

[0079] The beneficial effects of this utility model are as follows:

[0080] This utility model uses a locking member 110 that adapts to the shape of the strip-shaped protrusions 710 on the roof of the color steel tile 700, so that the support track 200 can be fixed more stably and conveniently between the strip-shaped protrusions 710, better fit the roof of the color steel tile 700, and the structure is stable and not easy to loosen. At the same time, it does not damage the original structure of the roof of the color steel tile 700, protects the original roof, and makes it less prone to water leakage.

[0081] In addition, by fixing the main water tank 300 to the support rail 200, the original structure of the roof can be protected, the water conduction capacity can be increased, and the waterproof effect can be fully achieved. After the installation of the photovoltaic module 600, the roof can also be protected from direct sunlight in strong sunlight weather or season, thereby reducing the roof temperature and effectively improving the environmental comfort of the factory or house.

[0082] In addition, by connecting and fixing the main water tank 300 to the support rail 200 through the water tank fixing component 400, the main water tank 300 can be prevented from shifting or falling off due to external factors such as strong winds, thus greatly improving the installation stability of the main water tank 300; at the same time, it can raise the installation height of the photovoltaic module 600 and the main water tank 300, avoiding the photovoltaic module 600 from getting wet during water diversion.

[0083] Adjacent water tank fixing parts 400 can also cooperate with each other to increase the load area and effectively distribute the load of the photovoltaic module 600.

[0084] Specifically, the intermediate pressure component 520 and the edge pressure component 510 can be used to press and fix the sides of the photovoltaic module 600 and adjacent photovoltaic modules 600, making them stable and firmly locked onto the water tank fixing component 400.
