Description

Technical Field

[0001] This invention relates to the field of building-integrated photovoltaics (BIPV) technology, specifically to a building rooftop power generation device based on BIPV and its installation method. Background Technology

[0002] With the continuous growth of global energy demand and the increasing awareness of environmental protection, the development and utilization of renewable energy has become an important trend. Solar energy, as a clean and sustainable energy form, is increasingly widely used in the building sector, especially in the design and installation of building rooftop photovoltaic (PV) power generation systems. Integrated photovoltaic (PV) technology, by combining PV power generation devices with the building structure, not only effectively utilizes the building surface for power generation but also enhances the overall aesthetics and functionality of the building. However, existing building rooftop PV power generation devices and their installation methods still have many shortcomings.

[0003] Currently, traditional photovoltaic (PV) installations are typically installed independently, resulting in complex structural designs, cumbersome installation processes, and high requirements for the load-bearing capacity of building roofs, which can easily place additional burdens on the building structure. Furthermore, existing technologies often have low integration between PV modules and building roofs, requiring additional supports or fixing devices, leading to poor overall system integration, low installation efficiency, and negatively impacting the consistency and aesthetics of the building's appearance. In practical applications, some PV installations also suffer from insufficient wind and waterproof performance, making them unsuitable for complex climatic conditions, further limiting their promotion and application scope.

[0004] Therefore, designing a photovoltaic (PV) integrated building rooftop power generation device that is both highly efficient and easy to install, and optimizing its installation methods to improve system integration, reduce construction difficulty, and enhance environmental adaptability, has become a pressing technical challenge. This invention aims to propose an innovative solution to address these problems, thereby promoting the widespread application of PV integrated technology in the building sector. Summary of the Invention

[0005] This invention relates to the field of building photovoltaic (PV) integration technology, and more particularly to a building rooftop power generation device based on PV integration and its installation method. The existing PV installation methods mentioned in the background art suffer from inaccurate positioning and low installation efficiency during construction. This invention proposes a building rooftop power generation device that can achieve rapid and accurate positioning and improve installation efficiency.

[0006] On one hand, the present invention proposes a building rooftop power generation device based on photovoltaic integration, including multiple support bases fixedly installed on the roof, a guide rail assembly slidably installed on the support bases, and further including: a photovoltaic panel mounting frame slidably installed on the guide rail assembly, the photovoltaic panel mounting frame being equipped with an adjustment component for adjusting the angle of the photovoltaic panel; and a positioning mechanism fixedly installed on the support bases, the positioning mechanism being used to accurately position the photovoltaic panel mounting frame so that the position of the photovoltaic panel mounting frame on the guide rail assembly remains consistent.

[0007] Optionally, the guide rail assembly includes a guide rail body fixedly mounted on a support base, a slide groove disposed within the guide rail body, a slider slidably mounted within the slide groove, a first lead screw rotatably mounted within the guide rail body, and a first motor fixedly mounted at one end of the guide rail body. The output shaft of the first motor is fixedly connected to the first lead screw, and the slider is threadedly connected to the first lead screw.

[0008] Optionally, the photovoltaic panel mounting frame is slidably mounted on the two guide rail assemblies. The adjustment assembly includes a second motor fixedly mounted on the photovoltaic panel mounting frame and adjustment rods rotatably mounted on both sides of the photovoltaic panel mounting frame. The output shaft of the second motor is coaxially and fixedly connected to one of the adjustment rods. A gear is fixedly mounted on the adjustment rod, and a rack is provided between the two gears. The rack meshes with the gear.

[0009] Optionally, the positioning mechanism includes a positioning component and a locking component. The positioning component is used to initially position the photovoltaic panel mounting frame, and the locking component is used to fix the photovoltaic panel mounting frame to the guide rail assembly.

[0010] Optionally, the positioning assembly includes a positioning seat fixedly mounted on a support base, a positioning rod rotatably mounted on the positioning seat, traction ropes wound around both sides of the positioning rod, and a third motor fixedly mounted on the positioning seat. The output shaft of the third motor is coaxially and fixedly connected to the positioning rod. A positioning block is fixedly mounted at one end of each of the two traction ropes, and the positioning block is slidably connected to the photovoltaic panel mounting frame.

[0011] Optionally, the locking assembly includes two locking plates slidably installed in the positioning seat and two electric push rods fixedly installed on the positioning seat. The two electric push rods correspond one-to-one with the two locking plates. The output shaft of the electric push rod passes through one side of the positioning seat and is fixedly connected to the locking plate. An anti-slip pad is fixedly installed on the locking plate.

[0012] Optionally, the adjustment mechanism includes a lateral adjustment mechanism and a longitudinal adjustment mechanism. The lateral adjustment mechanism is used to adjust the lateral position of the photovoltaic panel mounting frame, and the longitudinal adjustment mechanism is used to adjust the longitudinal position of the photovoltaic panel mounting frame.

[0013] Optionally, the lateral adjustment mechanism includes a sliding groove disposed within the guide rail body, lateral adjustment plates slidably mounted on both sides of the sliding groove, two bidirectional lead screws rotatably mounted on the guide rail body, a second pulley fixedly mounted on the bidirectional lead screws, a second linkage belt mounted on the two second pulleys, and a fourth motor fixedly mounted on the guide rail body. The output shaft of the fourth motor is coaxially and fixedly connected to one of the bidirectional lead screws. Connecting blocks are fixedly mounted on both sides of the two lateral adjustment plates, and the connecting blocks are threadedly connected to the bidirectional lead screws.

[0015] On the other hand, this invention proposes an installation method for a building rooftop power generation device based on photovoltaic integration, applicable to the above-mentioned power generation device. The method includes the following steps: Step 1: Place the photovoltaic panel mounting frame on the guide rail assembly; Step 2: Activate the horizontal adjustment mechanism and the vertical adjustment mechanism to adjust and fix the position of the photovoltaic panel mounting frame; Step 3: Precisely position the photovoltaic panel mounting frame using the positioning mechanism and lock it in place; Step 4: Adjust the angle of the photovoltaic panel to the optimal light-receiving position using the adjustment assembly; Step 5: After installation, check whether the stability and angle of the photovoltaic panel meet the requirements.

[0016] Compared with existing technologies, this invention has the following beneficial technical effects: By placing the photovoltaic panel mounting frame on the guide rail assembly, starting the fourth motor drives the two lateral adjustment plates on both sides to move closer together. When the two lateral adjustment plates move closer together, they push the photovoltaic panel mounting frame, moving its center to the center of the guide rail assembly, thus positioning the photovoltaic panel mounting frame laterally. Starting the push rod motor drives the two longitudinal adjustment plates to move closer together, allowing them to contact the photovoltaic panel mounting frame and move it so that its longitudinal center is aligned with the longitudinal center of the guide rail assembly, thereby completing the position adjustment of the photovoltaic panel mounting frame. At this time, the positioning mechanism maintains a consistent position for the photovoltaic panel mounting frame, requiring only one adjustment to the support base, eliminating the need for repeated adjustments to the photovoltaic panel mounting frame's position. This greatly improves the installation efficiency of the photovoltaic panels. Attached Figure Description

[0023] This invention proposes a building rooftop power generation device based on photovoltaic integration and its installation method, the specific implementation of which is described in conjunction with the appendix. Figure 1 To be continued Figure 4 Please provide a detailed explanation. For example... Figure 1 As shown, the overall structure of this invention includes a support base 1, a guide rail assembly 2, a photovoltaic panel mounting frame 3, an adjustment assembly 4, and a positioning mechanism 5. The specific structure, connection relationships, and operating principles of each component will be described in detail below.

[0024] First, support base 1 is fixedly installed on the building roof to provide a stable foundation for the entire device. The number of support bases 1 can be adjusted according to the actual roof area and the number of photovoltaic panels to ensure the stability and load-bearing capacity of the overall structure. Guide rail assembly 2 is fixedly installed on support base 1; its main function is to provide sliding tracks for the photovoltaic panel mounting frame 3 and to achieve precise positioning of the photovoltaic panel mounting frame 3 through an internal transmission mechanism. Figure 2 As shown, the guide rail assembly 2 includes a guide rail body 6, a slide groove 7, a slider 8, a first lead screw 9, and a first motor 10. The slide groove 7 is located inside the guide rail body 6, and the slider 8 is slidably installed in the slide groove 7 and threadedly connected to the first lead screw 9. The first lead screw 9 is rotatably installed inside the guide rail body 6, and the first motor 10 is fixedly installed at one end of the guide rail body 6, with its output shaft fixedly connected to the first lead screw 9. When the first motor 10 is started, the first lead screw 9 rotates and drives the slider 8 to move along the slide groove 7, thereby realizing the lateral position adjustment of the photovoltaic panel mounting bracket 3 on the guide rail assembly 2.

[0025] The photovoltaic panel mounting bracket 3 is slidably mounted on two guide rail assemblies 2, used to support the photovoltaic panels and adjust their angle. For example... Figure 4 As shown, the adjustment assembly 4 includes a second motor 11, an adjustment rod 12, a gear 13, and a rack 14. The second motor 11 is fixedly mounted on the photovoltaic panel mounting frame 3, and its output shaft is coaxially and fixedly connected to one of the adjustment rods 12. The adjustment rods 12 are rotatably mounted on both sides of the photovoltaic panel mounting frame 3, and gears 13 are fixedly mounted on them. A rack 14 is provided between the two gears 13, and the rack 14 meshes with the gears 13. When the second motor 11 is started, the adjustment rod 12 rotates, and the meshing action of the gears 13 and the rack 14 changes the angle of the photovoltaic panel, thereby adjusting the photovoltaic panel to the optimal light-receiving position. This design can adjust the angle of the photovoltaic panel in real time according to the change of the solar altitude angle, improving the photovoltaic power generation efficiency.

[0026] The positioning mechanism 5 is fixedly installed on the support base 1, and is used to accurately position the photovoltaic panel mounting frame 3 and fix it to the guide rail assembly 2. Figure 3 As shown, the positioning mechanism 5 includes a positioning component and a locking component. The positioning component includes a positioning seat 15, a positioning rod 16, a traction rope 17, and a third motor 18. The positioning seat 15 is fixedly installed on the support base 1, the positioning rod 16 is rotatably installed on the positioning seat 15, and the traction rope 17 is wound around both sides of the positioning rod 16, with a positioning block fixedly installed at one end. The positioning block is slidably connected to the photovoltaic panel mounting frame 3. The third motor 18 is fixedly installed on the positioning seat 15, and its output shaft is coaxially fixedly connected to the positioning rod 16. When the third motor 18 is started, the positioning rod 16 rotates and tightens or loosens the traction rope 17, thereby pulling the positioning block to perform preliminary positioning of the photovoltaic panel mounting frame 3. The locking component includes two locking plates 19 and two electric push rods 20. The locking plates 19 are slidably installed inside the positioning seat 15, and the electric push rods 20 are fixedly installed on the positioning seat 15, with their output shafts passing through one side of the positioning seat 15 and fixedly connected to the locking plates 19. An anti-slip pad 21 is fixedly installed on the locking plate 19 to increase friction during locking. When the electric push rod 20 is activated, the two locking plates 19 move closer to each other and clamp the photovoltaic panel mounting bracket 3, thereby completing the final fixing operation.

[0027] To further improve the positioning accuracy of the photovoltaic panel mounting frame 3, this invention also includes an adjustment mechanism, comprising a lateral adjustment mechanism and a longitudinal adjustment mechanism. The lateral adjustment mechanism is used to adjust the lateral position of the photovoltaic panel mounting frame 3, and its structure is as follows: Figure 2As shown, the system includes a sliding groove, a lateral adjustment plate 22, a bidirectional lead screw 23, a second pulley 24, a second linkage belt 25, and a fourth motor 26. The sliding groove is located within the guide rail body 6. The lateral adjustment plate 22 is slidably mounted on both sides of the sliding groove. The bidirectional lead screw 23 is rotatably mounted on the guide rail body 6, and the second pulley 24 is fixedly mounted on it. The second linkage belt 25 is mounted on the two second pulleys 24. The fourth motor 26 is fixedly mounted on the guide rail body 6, and its output shaft is coaxially fixedly connected to one of the bidirectional lead screws 23. When the fourth motor 26 starts, the bidirectional lead screw 23 rotates and, through the second linkage belt 25, drives the two lateral adjustment plates 22 closer together, thereby pushing the middle part of the photovoltaic panel mounting frame 3 to the center position of the guide rail assembly 2, completing the lateral positioning. The longitudinal adjustment mechanism is used to adjust the longitudinal position of the photovoltaic panel mounting frame 3, and its structure is as follows: Figure 2 As shown, the system includes a longitudinal adjustment plate 27, connecting rods 28, a drive plate 29, and a push rod motor 30. The longitudinal adjustment plate 27 is slidably mounted in a sliding groove, and the connecting rods 28 are rotatably mounted on both sides of the longitudinal adjustment plate 27. A drive plate 29 is rotatably mounted on multiple connecting rods 28. The drive plate 29 is slidably connected to the guide rail body 6, and the push rod motor 30 is fixedly mounted on the guide rail body 6, with its output shaft fixedly connected to the drive plate 29. When the push rod motor 30 is started, the drive plate 29 moves and pushes the two longitudinal adjustment plates 27 closer together through the connecting rods 28, thereby longitudinally positioning the photovoltaic panel mounting frame 3.

[0028] The installation method of the present invention includes the following steps: First, the photovoltaic panel mounting frame 3 is placed on the guide rail assembly 2; second, the horizontal adjustment mechanism and the vertical adjustment mechanism are activated to adjust and fix the position of the photovoltaic panel mounting frame 3. Specifically, the fourth motor 26 is activated to drive the horizontal adjustment plate 22 to perform horizontal positioning of the photovoltaic panel mounting frame 3, and the push rod motor 30 is activated to drive the vertical adjustment plate 27 to perform vertical positioning of the photovoltaic panel mounting frame 3; then, the photovoltaic panel mounting frame 3 is precisely positioned and locked by the positioning mechanism 5. Specifically, the third motor 18 is activated to tighten the traction rope 17 to pull the positioning block to perform preliminary positioning of the photovoltaic panel mounting frame 3, and the electric push rod 20 is activated to push the locking plate 19 to clamp the photovoltaic panel mounting frame 3 to complete the final fixation; next, the angle of the photovoltaic panel is adjusted to the optimal light-receiving position by the adjustment assembly 4. Specifically, the second motor 11 is activated to rotate the adjustment rod 12 and the angle of the photovoltaic panel is adjusted by the meshing action of the gear 13 and the rack 14; finally, after the installation is completed, the stability and angle of the photovoltaic panel are checked to see if they meet the requirements.

[0029] This invention achieves rapid and accurate positioning and efficient installation of the photovoltaic panel mounting frame 3 through the aforementioned structure and method, solving the problems of inaccurate positioning and low installation efficiency in the prior art. Positioning of the photovoltaic panel mounting frame 3 can be completed with a single adjustment of the support base 1, eliminating the need for repeated adjustments and greatly improving construction efficiency. Simultaneously, the design of the adjustment component 4 allows the photovoltaic panel to adjust its angle in real time according to changes in the solar altitude angle, further improving photovoltaic power generation efficiency.

Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
