[0005] As a limitation of this utility model: the upper surface of the mounting plate is fixedly provided with an annular protrusion, the inner diameter of the protrusion being larger than the diameter of the fixing component; the lower surface of the protective cover is provided with a cylindrical groove that is larger than the outer diameter of the protrusion and corresponds to the position of the protrusion.

[0006] As a limitation of this utility model: an annular limiting part for limiting the protective cover is fixedly provided on the top periphery of the inner wall of the protrusion. The outer diameter of the limiting part is between the inner diameter of the protrusion and the diameter of the fixing component, and the height of the limiting part is less than the height of the protrusion. Several elastic pieces arranged in a circular array are fixedly provided on the horizontal surface of the groove for mounting the protective cover on the top of the fixing component. The elastic pieces can be engaged with the lower part of the limiting part, and the height of the elastic pieces is less than or equal to the height of the protrusion.

[0007] As a limitation of this utility model: the elastic sheet includes an arc-shaped connecting part and an arc-shaped snap-fit ​​part. The connecting part is fixedly fixed downwards on the horizontal surface of the groove. The outer diameter of the ring corresponding to the arc formed by the orthographic projection of the connecting part is between the inner diameter of the limiting part and the diameter of the fixing part. The snap-fit ​​part is fixedly disposed at the lower end of the connecting part. The outer diameter of the ring corresponding to the arc formed by the orthographic projection of the snap-fit ​​part is between the inner diameter of the protrusion and the outer diameter of the limiting part.

[0008] As a limitation of this utility model: the photovoltaic module and the color steel roof connection device further includes a fastening component for penetrating the raised part of the color steel plate and abutting against the upper surface of the roof beam, and the fastening component is fixedly installed on the lower surface of the mounting plate.

[0009] As a limitation of this utility model, the fastening component is a cylinder.

[0010] As a limitation of this utility model: the connecting component is a side pressure block, which includes a first horizontal part, a vertical part, and a second horizontal part; the surface of the first horizontal part has bolt holes with the same number as the number of mounting holes and corresponding to the mounting holes, and bolts pass through the bolt holes simultaneously, with nuts fitted at the lower ends of the bolts; the bottom end of the vertical part is fixedly located at the end of the first horizontal part away from the mounting holes, and the end of the second horizontal part near the mounting holes is fixedly located at the top end of the vertical part; the lower surface of the second horizontal part and the color steel plate have a space to accommodate the edge of the photovoltaic module.

Furthermore, an annular protrusion is fixedly provided on the upper surface of the mounting plate, and a cylindrical groove that matches the protrusion is formed on the lower surface of the protective cover. After the protrusion and the groove are interlocked, the protective cover can be placed on the upper part of the fixing component, effectively preventing rainwater from seeping into the roof through the through hole. The protrusion can further block rainwater from seeping into the roof through the through hole, thus improving waterproofing.

[0013] Meanwhile, by fixing an annular limiting part to the top periphery of the inner wall of the protrusion, a gap is formed between the lower part of the limiting part and the inner wall of the protrusion. An elastic piece that can be locked in the gap is fixed on the horizontal surface of the groove, which can firmly install the protective cover on the top of the fixed component. This not only serves as a waterproof function, but also hides other mechanical parts, making the connection between the photovoltaic module and the color steel roof neater and more aesthetically pleasing.

[0014] Furthermore, by utilizing the corrugated structure of the color steel sheet, the fastening components on the lower surface of the mounting plate are inserted into the fastening holes of the raised portion of the color steel sheet. This prevents the mounting plate from rotating around the fixing components, thus ensuring the photovoltaic modules are securely mounted on the color steel sheet. By replacing the fastening components with different lengths, the above device can be adapted to various types of corrugated color steel sheet roofs, improving market applicability and flexibility.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or component must have a specific orientation, or that it must be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the content protected by this utility model.

[0024] A photovoltaic module and color steel roof connection device, such as Figures 1 to 5As shown, the system includes a mounting plate 3 detachably mounted on the upper surface of the corrugated steel sheet 1. The mounting plate 3 has a first through hole 13. A second through hole 14, the same size and corresponding in position to the first through hole 13, is formed on the raised portion of the steel sheet 1. A third through hole, the same size and corresponding in position to the second through hole 14, is formed on the roof beam 2. A columnar fixing component 4 passes through the first through hole 13, the second through hole 14, and the third through hole on the mounting plate 3, the steel sheet 1, and the roof beam 2 sequentially from top to bottom, fixing the mounting plate 3 to the upper surface of the steel sheet 1. In this embodiment, the fixing component 4 includes a bolt and a nut fitted at the lower end of the bolt. By tightening the nut and making it fit against the lower surface of the roof beam 2, the mounting plate 3 can be securely installed on the upper surface of the steel sheet 1. The diameter of the bolt shank is the same as that of the first through hole 13, the second through hole 14, and the third through hole. The diameter of the bolt head is larger than that of the bolt shank. When the bolt is inserted into the through hole, the lower surface of the bolt head can rest on the upper surface of the mounting plate 3.

[0025] A protective cover 5 is detachably installed on the top of the fixing component 4 to prevent rainwater from seeping in. By covering the upper part of the fixing component 4 with the protective cover 5, rainwater can be effectively prevented from seeping into the roof through the opening. Specifically, such as... Figure 4 As shown, an annular protrusion 7 is fixedly provided on the upper surface of the mounting plate 3 around the first through hole 13. The outer diameter of the protrusion 7 is larger than the diameter of the fixing component 4 and the first through hole 13. Figure 3 As shown, the lower surface of the protective cover 5 has a cylindrical groove 8 that is larger than the outer diameter of the protrusion 7 and corresponds to the position of the protrusion 7. After the protrusion 7 and the groove 8 are engaged, the protective cover 5 can be placed on the upper part of the fixing component 4. Since the top of the protrusion 7 is higher than the upper surface of the mounting plate 3, it can further prevent rainwater from seeping into the roof through the through hole, thus improving the waterproofness of this embodiment.

[0026] Furthermore, an annular limiting part 9 for limiting the protective cover 5 is fixedly provided on the top periphery of the inner wall of the protrusion 7. The outer diameter of the limiting part 9 is between the inner diameter of the protrusion 7 and the diameter of the fixing member 4, and the height of the limiting part 9 is less than the height of the protrusion 7. At the same time, the diameter of the bolt head is smaller than the inner diameter of the limiting part 9, so as to facilitate the placement of the bolt in the space inside the protrusion 7. Several elastic plates arranged in a circular array are fixedly provided on the horizontal surface of the groove 8 for mounting the protective cover 5 on the top of the fixing member 4. In this embodiment, the number of elastic plates is four.

[0027] The elastic sheet includes an arc-shaped connecting portion 10 and an arc-shaped locking portion 11. The connecting portion 10 is vertically fixed downward on the horizontal surface of the groove 8. The outer diameter of the ring corresponding to the arc formed by the orthographic projection of the connecting portion 10 is between the inner diameter of the limiting portion 9 and the diameter of the fixing member 4, facilitating the placement of the connecting portion 10 between the limiting portion 9 and the fixing member 4. The locking portion 11 is fixedly disposed at the lower end of the connecting portion 10. The outer diameter of the ring corresponding to the arc formed by the orthographic projection of the locking portion 11 is between the inner diameter of the protrusion 7 and the outer diameter of the limiting portion 9.

[0028] like Figure 5 As shown, the surface of the limiting part 9 away from the protrusion 7 is arc-shaped. A gap is formed between the lower part of the limiting part 9 and the inner wall of the protrusion 7 to accommodate the elastic sheet. Therefore, the lower end of the elastic sheet can be engaged in the gap at the lower part of the limiting part 9, and the protective cover 5 is firmly placed on the mounting plate 3, thereby shielding the upper part of the fixing component 4. This not only provides waterproofing but also hides other mechanical components, making the connection between the photovoltaic module and the color steel roof neater and more aesthetically pleasing. At the same time, the height of the elastic sheet is less than or equal to the height of the protrusion 7 so that the elastic sheet can be engaged in the gap.

[0029] When the protective cover 5 is pressed down, the latching part 11 is first squeezed by the upper part of the limiting part 9 and retracts inward. As the latching part 11 continues to move downward to the lower part of the limiting part 9, the squeezing effect of the limiting part 9 on the latching part 11 decreases, and the latching part 11 can enter the gap between the lower part of the limiting part 9 and the inner wall of the protrusion 7 and expand outward. The upper surface of the latching part 11 will fit against the lower surface of the limiting part 9. Therefore, by utilizing the elastic force of the elastic sheet, the protective cover 5 can be firmly installed on the mounting plate 3, preventing the protective cover 5 from falling off due to external factors, thereby effectively improving the waterproof performance of this embodiment.

[0030] Furthermore, several fastening holes 15 are provided around the second through hole 14. A columnar fastening component 12, the same number as the fastening holes 15 and corresponding in position to the fastening holes 15, is fixedly provided on the lower surface of the mounting plate 3. The diameters of the fastening holes 15 and the fastening components 12 are the same. In this embodiment, there are four fastening holes 15 and four fastening components 12, which are evenly arranged around the second through hole 14 and the first through hole 13, respectively. The fastening component 12 can penetrate the raised portion of the color steel plate 1 and abut against the upper surface of the roof beam 2. By inserting the fastening component 12 into the fastening hole 15 and making the lower surface of the fastening component 12 abut against the upper surface of the roof beam 2, the mounting plate 3 can be prevented from rotating around the fixing component 4, thus making the mounting plate 3 more stably fixed to the upper surface of the color steel plate 1. In addition, the fastening component 12 can also support the raised portion of the color steel plate 1, avoiding the risk of loosening of the photovoltaic module due to deformation of the color steel plate 1.

[0031] By utilizing the corrugated structure of the color steel plate 1, the mounting plate 3 is fixed to the raised part of the color steel plate 1. This prevents rainwater from accumulating in the recessed parts of the color steel plate 1 and soaking the mounting plate 3, thus reducing the risk of rainwater seeping into the house through the through holes. The surface of the mounting plate 3 is also provided with several mounting holes 6 for installing photovoltaic modules. This embodiment also includes a connecting component that is detachably connected to the mounting holes 6 for connecting the photovoltaic modules to the color steel plate 1.

[0032] Specifically, the connecting component is a side clamping block, which includes a first horizontal part 16, a vertical part 17, and a second horizontal part 18. The surface of the first horizontal part 16 has bolt holes of the same number as the mounting holes 6, and the positions of these bolt holes correspond to those of the mounting holes 6. Bolts pass through these bolt holes, and nuts are fitted onto the lower ends of the bolts. For example... Figure 5 As shown, since the thickness of the right side of the mounting plate 3 is greater than the thickness of the left side of the mounting plate 3, after the mounting plate 3 is placed over the raised part of the color steel plate 1, a space for accommodating the nut is formed between the left side of the mounting plate 3 and the color steel plate 1. The bolt hole and the mounting hole 6 at one end of the first horizontal part 16 are aligned, and a bolt is inserted into both the bolt hole and the mounting hole 6. A nut is fitted onto the part of the bolt located on the lower side of the mounting plate 3. By tightening the nut and making it fit against the lower surface of the mounting plate 3, the edge pressure block is fixedly installed on the mounting plate 3.

[0033] The bottom end of the vertical part 16 is fixedly disposed at the end of the first horizontal part 16 away from the mounting hole 6, and the end of the second horizontal part 18 near the mounting hole 6 is fixedly disposed at the top end of the vertical part 16; the lower surface of the second horizontal part 18 and the color steel plate 1 have a space to accommodate the edge of the photovoltaic module. The edge of the photovoltaic module is then placed in the space between the second horizontal part 18 and the color steel plate 1, thereby clamping the photovoltaic module onto the top of the color steel plate 1. Furthermore, by replacing the fastening components 12 of different lengths, this embodiment can be applied to various types of corrugated color steel plate roofs, improving market applicability and flexibility.

[0034] In using this embodiment, firstly, align the bolt hole and mounting hole 6 at one end of the first horizontal part 16, insert a bolt through both the bolt hole and the mounting hole 6, and fit a nut on the part of the bolt located on the lower side of the mounting plate 3. By tightening the nut and making it fit against the lower surface of the mounting plate 3, the edge pressure block is fixedly installed on the mounting plate 3. Secondly, a second through hole 14 and a fastening hole 15 are opened on the upper surface of the raised part of the color steel plate 1. Insert the fastening component 12 into the fastening hole 15, so that the lower end of the fastening component 12 and the roof... The upper surfaces of the top crossbeam 2 are in contact with each other, and bolts are passed through the first through hole 13, the second through hole 14, and the third through hole in sequence. The nuts at the lower ends of the bolts are tightened to make them fit against the lower surface of the roof crossbeam 2, thereby fixing the mounting plate 3 on the upper surface of the color steel plate 1. Then, the protective cover 5 is fastened on top of the mounting plate 3, and the protective cover 5 is pressed down. Under the squeezing action of the limiting part 9, the elastic sheet first contracts inward and then expands outward, thereby locking the elastic sheet under the limiting part 9, thus realizing the installation of the protective cover 5. Repeat the above steps to continue installing this embodiment on the color steel plate 1. Then, the side of the photovoltaic module is placed simultaneously in the space between the lower surface of the second horizontal part 18 and the color steel plate 1, forming a multi-point clamping of the photovoltaic module, thereby fixing the photovoltaic module to the upper surface of the color steel plate 1.
