Description

Technical Field

[0001] The present application relates to the field of photovoltaic roofs, and in particular, to an installation structure of a photovoltaic roof and a photovoltaic roof applying this structure. Background Art

[0002] Photovoltaic building is a technology that integrates photovoltaic products into buildings. According to the different ways of combining the photovoltaic array with the building, the building-integrated photovoltaic can be divided into the combination of the photovoltaic array and the building, and the integration of the photovoltaic array and the building. Among them, the photovoltaic roof is an integrated building that combines photovoltaic products with the roof surface of the building. Since the combination of photovoltaic products and the building does not occupy additional ground space, it is the best installation method for the wide application of photovoltaic power generation systems in cities.

[0003] Currently, for the installation of existing photovoltaic products, usually purlins are installed on the steel beams on the roof, and then alloy profiles for positioning the photovoltaic products are installed on the purlins. Then, the photovoltaic products are installed on the purlins through the alloy profiles and positioned, thus completing the installation of the photovoltaic products. Generally, traditional alloy profiles generally include a bottom plate, a load-bearing vertical plate, and a groove frame. The bottom plate is used to connect to the building. One end of the load-bearing vertical plate is fixedly installed on the bottom plate, and the other end is fixedly connected to the side wall of the groove frame, thereby forming a frame. The groove frame is provided with an installation groove for clamping the photovoltaic products. By fixedly connecting the bottom plate to the purlin and then installing the photovoltaic products in the installation groove, the construction of the photovoltaic roof is completed.

[0004] However, as the installation years of the photovoltaic products increase, after the photovoltaic products on the roof have experienced long-term wind and rain, the load-bearing vertical plates on the alloy profiles for installing the photovoltaic products are prone to bending deformation, resulting in an unstable installation of the photovoltaic products. Summary of the Invention

[0005] In order to enable the photovoltaic products to be stably installed on the roof, the present application provides an installation structure of a photovoltaic roof and a photovoltaic roof applying this structure.

[0006] In the first aspect, the present application provides an installation structure of a photovoltaic roof, adopting the following technical solution:

[0007] An installation structure of a photovoltaic roof, comprising a longitudinal water guide strip, wherein the longitudinal water guide strip includes a first support plate, a second support plate, a third support plate and a fourth support plate. The first support plate and the third support plate are connected by a first vertical plate, the second support plate and the fourth support plate are connected by a second vertical plate. The first support plate and the second support plate are connected by a water chute plate, and a chute is arranged on the water chute plate. A positioning mechanism is installed in the chute. The third support plate and the fourth support plate are connected by a mounting plate. The first support plate, the water chute plate, the second support plate, the second vertical plate, the fourth support plate, the mounting plate, the fourth support plate and the first vertical plate enclose to form a receiving cavity, and an auxiliary support assembly is installed in the receiving cavity.

[0008] By adopting the above technical solution, the photovoltaic product is installed on the longitudinal water guide strip, and the first support plate and the second support plate support the photovoltaic product. At the same time, the photovoltaic product is positioned by a positioning member. When it rains, the chute formed by the water chute plate is used for drainage. When the longitudinal water guide strip deforms after the photovoltaic product has been installed for a certain period of time, the auxiliary support assembly supports the photovoltaic product, thereby increasing the support strength of the longitudinal water guide strip and facilitating the stable installation of the photovoltaic product on the roof.

[0009] In a specific feasible embodiment, a first side plate is installed at one end of the third support plate away from the mounting plate, and a first bearing plate is installed at one end of the first side plate away from the third support plate. A second side plate is installed at one end of the fourth support plate away from the mounting plate, and a second bearing plate is installed at one end of the second side plate away from the fourth support plate. The top walls of the first bearing plate, the first support plate, the second support plate and the second bearing plate are all on the same straight line.

[0010] By adopting the above technical solution, there is a gap between the first side plate and the first vertical plate, and there is a gap between the second side plate and the second vertical plate, which facilitates the discharge of rainwater. At the same time, the photovoltaic product is supported by the first bearing plate and the second bearing plate. Moreover, a triangular structure is formed among the first side plate, the first vertical plate and the photovoltaic product, and a triangular structure is also formed among the second side plate, the second vertical plate and the photovoltaic product, thereby increasing the stability of the support of the photovoltaic product.

[0011] In a specific feasible embodiment, the positioning mechanism includes a pressing block, a positioning bolt and a fixing plate. The pressing block is installed in the chute, and both ends of the pressing block are respectively in contact with one ends of the first support plate and the second support plate located in the chute. The fixing plate is connected to the pressing block through the positioning bolt. A first pressing plate is installed on one side of the fixing plate, and a first clamping groove for installing a photovoltaic panel is formed between the first pressing plate and the first support plate. A second pressing plate is installed on the other side of the fixing plate, and a second clamping groove for installing a photovoltaic panel is formed between the second pressing plate and the second support plate.

[0012] By adopting the above technical solution, the photovoltaic product is placed on the first support plate and the second support plate, then the pressing block is loaded into the chute, and then the fixing plate is connected to the pressing block through the positioning bolts, so that the first pressing plate and the second pressing plate press the photovoltaic product, thereby completing the installation of the photovoltaic product and keeping the photovoltaic product stable.

[0013] In a specific feasible implementation, the auxiliary support assembly includes a support member, a linkage member and a control member. A fixed block is installed on the side wall of the mounting plate. The support member includes a support rod, a first connecting rod and a second connecting rod. A support groove is formed in the fixed block. The support rod is installed on the fixed block, and one end of the support rod extends into the support groove. One end of the first connecting rod is connected to the bottom wall of the support groove, and the other end is connected to one end of the second connecting rod. The end of the second connecting rod far from the first connecting rod is connected to the side wall of the support rod located in the support groove. The linkage member is installed in the fixed block, and the linkage member is connected to the connection parts of the first connecting rod and the second connecting rod. The control member is installed on the fixed block, and the control member is connected to the linkage member.

[0014] By adopting the above technical solution, when the longitudinal water guide strip deforms, the distance between the water chute plate and the mounting plate will decrease, so that the water chute plate touches the control member, and the control member drives the second connecting rod and the first connecting rod to act through the linkage member. The first connecting rod rotates around the bottom wall of the support groove, and the support rod is pushed upward through the second connecting rod, so that the first connecting rod, the second connecting rod and the support rod are in the same straight line, thereby supporting the first support plate and the second support plate, which is convenient for improving the strength of the longitudinal water guide strip and the stability of the installation of the photovoltaic product.

[0015] In a specific feasible implementation, the linkage member includes a sliding column. A sliding groove is formed in the fixed block, and the sliding groove communicates with the support groove. The sliding column is installed in the sliding groove, and one end of the sliding column extends into the support groove. The end of the sliding column located in the support groove is connected to the connection parts of the first connecting rod and the second connecting rod, and the other end of the sliding column is connected to the control member.

[0016] By adopting the above technical solution, when the control member works, it drives the sliding column to slide in the sliding groove, so that the sliding column can push the first connecting rod to rotate, and the first connecting rod drives the second connecting rod to move, so that the support rod moves upward, realizing the support for the first support plate and the second support plate.

[0017] In a specific feasible implementation, a positioning member for positioning the sliding column is arranged in the fixed block. The positioning member includes a positioning spring and a positioning plate. The positioning plate and the positioning spring are both installed in the fixed block. One end of the positioning spring is connected to the inner wall of the fixed block, and the other end is connected to one end of the positioning plate. The end of the positioning plate far from the positioning spring is connected to the side wall of the sliding column.

[0018] By adopting the above technical solution, when the control member pushes the sliding column to slide in the sliding groove, after the sliding column enters the sliding groove, the positioning plate moves to the end of the sliding column under the action of the positioning spring, so as to position the sliding column, thereby reducing the driving of the sliding column to move when the support rod is stressed and moves downward, and facilitating the maintenance of the stability of the support of the support rod.

[0019] In a specific feasible embodiment, the control member includes a control column, a control spring, a first control rod and a second control rod. A control groove is formed in the side wall of the fixed block, and the control groove communicates with the sliding groove. The control column is installed in the control groove, and one end of the control column extends out of the control groove. A convex block is installed on the side wall of the control column, and the convex block abuts against the end of the sliding column. A limiting plate is also installed on the side wall of the control column. The control spring is installed on the control column. One end of the control spring is connected to the limiting plate, and the other end is connected to the side wall of the control groove. The first control rod is installed on one side of the control column outside the control groove. A first control piece is installed at one end of the first control rod, and one end of the first control piece extends into the gap between the control column and the control groove. The second control rod is installed on the other side of the control column, and one end of the second control rod is connected to the end of the first control rod away from the first control hook. A second control piece is installed at the other end of the second control rod, and one end of the second control piece extends into the gap between the control column and the control groove.

[0020] By adopting the above technical solution, when the longitudinal water guide strip is in a normal state, the first control piece and the second control piece are located in the gap between the control column and the control groove, and are in close contact with the side wall of the control column and the side wall of the control groove, so as to limit the control column, thereby reducing the movement of the control column under the action of the control spring. When the longitudinal water guide strip deforms, the water chute plate touches the first control rod and the second control rod, so that the first control rod and the second control rod rotate, so that the first control piece and the second control piece are separated from the gap between the control column and the control groove, so that the control column moves downward under the action of the control spring, so that the convex block on the control column pushes the sliding column to move, so that the sliding column drives the support rod to support the first support plate and the second support plate.

[0021] In a second aspect, the present application provides a photovoltaic roof, including a house main body. Purlin strips are laid on the top of the house main body, and a plurality of longitudinal water guide strips are laid on the purlin strips. A plurality of transverse water guide strips are laid between adjacent two of the longitudinal water guide strips. The longitudinal water guide strips and the transverse water guide strips are communicated. A photovoltaic panel is installed between adjacent two of the longitudinal water guide strips, and the photovoltaic panel is located between adjacent two of the transverse water guide strips.

[0022] By adopting the above technical solution, longitudinal water guide strips and transverse water guide strips are laid on the purlin strips on the house main body to facilitate the installation of the photovoltaic panel. At the same time, rainwater can be discharged from the roof through the longitudinal water guide strips and the transverse water guide strips.

[0023] In a specific feasible embodiment, a cover plate is installed on the longitudinal water guide strip, and the cover plate is inserted into the positioning plate.

[0024] By adopting the above technical solution, the cover plate is used to reduce the entry of rainwater into the gaps between the photovoltaic panels, thereby reducing the damage to the photovoltaic panels.

[0025] In a specific feasible embodiment, a drainage tank is further installed on the top of the house main body, and the longitudinal water guide strip is communicated with the drainage tank.

[0026] By adopting the above technical solution, the drainage tank is used to guide the rainwater in the longitudinal water guide strip into the drainage tank, thereby collecting the rainwater and discharging it centrally.

[0027] In summary, the present application includes at least one of the following beneficial effects:

[0028] 1. By providing the longitudinal water guide strip in the present application, the positioning and installation of the photovoltaic panels are facilitated.

[0029] 2. By providing the auxiliary support assembly in the present application, it is convenient to support the photovoltaic panel through the auxiliary support assembly when the longitudinal water guide strip deforms, so as to facilitate the stable installation of the photovoltaic panel on the roof.

One end of the first control piece 349 away from the first control rod 345 extends into the gap between the control column 341 and the control groove 314, and the first control piece 349 abuts against the side wall of the control groove 314 and the side wall of the control column 341. The control column 341 is kept stationary by the frictional force generated when the first control piece 349 is pressed against the side wall of the control groove 314 and the side wall of the control column 341.

[0055] Referring to Figure 6 and Figure 7 , a waist-shaped hole 348 is formed in the side wall of the second control rod 346. The second control rod 346 is rotatably installed on the other side of the end of the control column 341 located outside the control groove 314 through the waist-shaped hole 348. The end of the second control rod 346 close to the first control rod 345 is rotatably connected to the first control rod 345. A second control piece 3410 is fixedly installed at the end of the second control rod 346 away from the first control rod 345. One end of the second control piece 3410 away from the second control rod 346 extends into the gap between the control groove 314 and the control column 341, and the second control piece 3410 abuts against the side wall of the control groove 314 and the side wall of the control column 341. The control column 341 is kept stationary by the frictional force generated when the second control piece 3410 is pressed against the side wall of the control groove 314 and the side wall of the control column 341.

[0056] Referring to Figure 6, a limiting plate 342 is fixedly installed on the side wall of the control column 341 located in the control groove 314. A control spring 344 is sleeved on the control column 341, and one end of the control spring 344 abuts against the top wall of the limiting plate 342, and the other end abuts against the inner wall of the control groove 314. In the initial state, the control spring 344 is in a compressed state. A convex block 343 is fixedly installed on the side wall of the control column 341, and a groove 315 for the convex block 343 to slide is formed on the side wall of the control groove 314. The convex block 343 abuts against the end of the sliding column 331.

[0057] Referring to Figure 4 and Figure 6 , a positioning member for positioning the sliding column 331 is installed in the fixing block 31. The positioning member includes a positioning plate 332 and a positioning spring 333. A positioning groove 313 is formed on the side wall of the sliding groove 312 at the position of the groove 315. The positioning plate 332 is slidably installed in the positioning groove 313, and one end of the positioning plate 332 abuts against the side wall of the sliding column 331.

In the initial state, the positioning spring 333 is in a compressed state.

[0058] Referring to Figure 8 and Figure 9, when the longitudinal water guide strip 1 is deformed after long-term use, the distance between the water chute plate 15 and the mounting plate 16 will decrease, causing the water chute plate 15 to contact the first control rod 345 and the second control rod 346, so that the first control rod 345 and the second control rod 346 rotate around the control column 341, and thus pull the first control piece 349 and the second control piece 3410 out of the gap between the control column 341 and the control groove 314. As a result, under the action of the control spring 344, the control column 341 moves downward, so that the first control rod 345 and the second control rod 346 touch the top wall of the fixed block 31 and rotate around the control column 341 under the action of the top wall of the fixed block 31, making the connecting part of the first control rod 345 and the second control rod 346 rotate into the deflection groove 3411. At the same time, the convex block 343 on the control column 341 pushes the sliding column 331 towards the support groove 311, so that the sliding column 331 drives the first connecting rod 323 to rotate, and makes the first connecting rod 323, the second connecting rod 324 and the support rod 321 in a straight line, so that the support rod 321 moves upward and contacts the first support plate 11, thereby increasing the support performance of the first vertical plate 17. When the sliding column 331 slides in the sliding groove 312 driven by the convex block 343 until the control spring 344 is in a relaxed state, the side wall of the sliding column 331 moves relative to the end of the positioning plate 332, and finally the side wall of the sliding column 331 is separated from the positioning plate 332, so that the positioning plate 332 returns to the relaxed state under the action of the positioning spring 333, so that the side wall of the positioning plate 332 contacts the end of the sliding column 331, thereby limiting the sliding column 331 and improving the support of the support rod 321.

[0059] The working principle of the embodiment of the present application is as follows: A number of longitudinal water guide strips 1 are laid on the roof, and the longitudinal water guide strips 1 are fixed to the roof by installing screws in the installation grooves 114. Then, the photovoltaic panel is installed in the first clamping groove and the second clamping groove on two adjacent longitudinal water guide strips 1. Then, the positioning bolt 22 is adjusted so that the two ends of the pressing block 21 contact the ends of the first support plate 11 and the second support plate 12 located in the sliding groove 113, thereby using the pressing block 21 to limit the positioning bolt 22, and driving the fixing plate 23 to move downward under the drive of the positioning bolt 22, so that the first pressing block 21 and the second pressing block 21 press the photovoltaic panel tightly.

[0060] When the longitudinal water guide bar 1 deforms after long-term use, the water chute plate 15 touches the control rod 1 345 and the control rod 2 346, causing the control rod 1 345 and the control rod 2 346 to rotate. As a result, the control piece 1 349 and the control piece 2 3410 disengage from the gap between the control column 341 and the control groove 314, enabling the control column 341 to reset under the action of the control spring 344. Then, the bump 343 on the control column 341 pushes the sliding column 331 to move, causing the sliding column 331 to drive the link 1 323 and the link 2 324 to act, making the support rod 321 abut against the bottom wall of the support plate 1 11, thereby increasing the support strength of the longitudinal water guide bar 1 and enabling the photovoltaic panel to remain stable on the longitudinal water guide bar 1. Moreover, when the longitudinal water guide bar 1 deforms, its support performance has deteriorated. Therefore, when the later staff repairs the roof where the longitudinal water guide bar 1 is installed, it is only necessary to replace the deformed longitudinal water guide bar 1.

[0061] The embodiment of the present application also discloses a photovoltaic roof. Referring to Figure 10 and Figure 11 , it includes a house main body 4. A plurality of purlins 5 are fixedly laid on the top of the house main body 4. A plurality of longitudinal water guide bars 1 are fixedly laid on the purlins 5. A plurality of transverse water guide bars 6 are also laid between adjacent two longitudinal water guide bars 1. The transverse water guide bars 6 are communicated with the water trough 1 116 and the water trough 2 117 on the longitudinal water guide bars 1. A photovoltaic panel is installed between adjacent two longitudinal water guide bars 1, and the photovoltaic panel is located between adjacent two transverse water guide bars 6.

[0062] Referring to Figure 12 and Figure 13 , a cover plate 7 is further installed on the longitudinal water guide bar 1. The cover plate 7 is inserted into the groove 315 of the positioning plate 332. A sealing strip 8 is installed between the gaps of adjacent two photovoltaic panels. The sealing strip 8 is located above the transverse water guide bar 6 and is parallel to the transverse water guide bar 6.

[0063] Referring to Figure 10 and Figure 11 , a drainage frame 9 is fixedly installed on the side wall of the top of the house main body 4. A drainage box 10 is fixedly installed on the side wall of the top of the house main body 4 adjacent to the drainage frame 9. The drainage box 10 is connected to the drainage frame 9, and the longitudinal water guide bar 1 is connected to the drainage box 10. A drain pipe for discharging the rainwater in the drainage box 10 is fixedly installed on the bottom wall of the drainage box 10.

[0064] The working principle of the embodiment of this application is as follows: A number of longitudinal water guide strips 1 are fixedly installed on several purlins 5 laid on the roof, and transverse water guide strips 6 are installed between two adjacent longitudinal water guide strips 1, and the transverse water guide grooves are perpendicular to the longitudinal water guide strips 1. One end of the transverse water guide strip 6 is communicated with the water tank 116 of the longitudinal water guide strip 1, and the other end of the transverse water guide strip 6 is communicated with the water tank 117 of the adjacent longitudinal water guide strip 1. Then, the photovoltaic panel is installed between two adjacent longitudinal water guide strips 1, and the photovoltaic panel is also located between two adjacent transverse water guide strips 6. After the installation of the photovoltaic panel is completed, a cover plate 7 is installed on the positioning plate 332. Then, drainage frames 9 are installed on the side walls on the opposite sides of the top of the house body 4, and drainage tanks 10 are fixedly installed on the side walls adjacent to the drainage frames 9 on the top of the house body 4, so that the drainage tanks 10 are connected to the drainage frames 9 and the longitudinal water guide strips 1, and a drain pipe for drainage is installed on the bottom wall of the drainage tank 10, thus completing the erection of the photovoltaic roof.

[0065] During the subsequent use process, rainwater flows through the transverse water guide strip 6 into the drainage frame 9 and the longitudinal water guide strip 1, and then flows into the drainage tank 10 and is discharged from the drain pipe in the drainage tank 10. When the longitudinal water guide strip 1 deforms after long-term use, the support performance of the longitudinal water guide strip 1 is enhanced through the auxiliary support assembly 3, so that the photovoltaic panel remains stable on the roof. And when the subsequent maintenance personnel repair the roof, they only need to replace the deformed longitudinal water guide strip 1.

[0066] The above is the preferred embodiment of this application. It does not limit the protection scope of this application accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
