Description

Technical Field

[0001] This invention relates to the field of photovoltaic building technology, and more particularly to a photovoltaic building integrated roof. Background Technology

[0002] With the global energy crisis and environmental problems becoming increasingly severe, building-integrated photovoltaics (BIPV) technology has emerged. This technology can organically combine building roofs with photovoltaic power generation functions, becoming one of the key technologies for promoting the development of green energy.

[0003] Traditional solar photovoltaic (PV) power generation systems are typically installed on the ground or on specialized supports, a method with significant drawbacks: it not only occupies valuable land resources but can also create visual disharmony. In contrast, building-integrated photovoltaic (BIPV) roofing technology offers unique advantages. It cleverly integrates PV modules with the building's roof, making full use of roof space and resulting in a more aesthetically pleasing and harmonious building appearance. Specifically, this technology converts solar energy into electricity by installing PV modules on the building's roof.

[0004] However, traditional building-integrated photovoltaics (BIPV) technology also faces numerous challenges in practical applications. Firstly, it typically uses fixed-angle installation of photovoltaic modules. Furthermore, due to structural design and installation limitations, these modules are easily damaged by hailstorms, threatening building and personal safety. This not only damages the photovoltaic system but can also lead to significant economic losses and safety hazards. Summary of the Invention

[0005] The purpose of this invention is to address the numerous challenges faced by traditional building-integrated photovoltaics (BIPV) technology in practical applications. Firstly, it typically employs fixed-angle installation of photovoltaic modules. Furthermore, due to structural design and installation limitations, photovoltaic modules are easily damaged by hailstorms, threatening building and personal safety. This situation not only damages the photovoltaic system but can also lead to serious economic losses and safety hazards. Therefore, this invention proposes a solution.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a photovoltaic building integrated roof, comprising a plurality of bases installed on a base plate, and further comprising: a flipping component disposed on the base, wherein the base plate, the bases, and the flipping component constitute an integrated roof; The flipping assembly includes a support fixed on a base. The support is connected to a rotating plate via an internally rotatable rotating shaft. A photovoltaic tile is mounted on the rotating plate. An extension frame is fixed on one side of the support. A slot is opened on the outer periphery of the rotating shaft, and a limiting block is slidably connected to the inner wall of the slot. A rotating gear and a half gear that are far apart from each other are fixed on the outer periphery of the limiting block. An extension plate and a mounting frame are fixed on the outer wall of the extension frame that are far apart from each other. A double-sided gear belt that meshes with the rotating gear and the half gear is rotatably connected to the outer wall of the extension frame and the extension plate. A driving component is mounted on one side of the mounting frame. The inner wall of the extension frame is provided with a pushing component. As the driving component drives the double-sided gear belt to rotate, multiple rotating gears drive the rotating shaft to rotate, causing the rotating plate to flip over so that the back faces upward.

[0007] As a further description of the above technical solution: The drive unit includes a servo motor mounted on one side of the mounting bracket. The output end of the servo motor passes through the mounting bracket and is connected to the main gear, and the main gear meshes with the double-sided gear belt.

[0008] As a further description of the above technical solution: The pushing assembly includes a fixed plate fixed to the inner wall of the extension frame and a ring fixed to the side of the half gear away from the rotating gear. An electric push rod is installed on one side of the fixed plate, and the extension end of the electric push rod is fixedly connected to the pushing plate.

[0009] As a further description of the above technical solution: The ring has an inner groove, and the push plate is movably embedded inside the inner groove.

[0010] As a further description of the above technical solution: The base is provided with a buffer assembly, which includes a snap-fit ​​plate between the inner walls of the fixed base, an extension block is fixed to the top of the snap-fit ​​plate, and a sliding rod is slidably connected to the inner wall of the extension block. A contact plate that contacts the rotating gear is fixed to one side of the sliding rod, and several first gear teeth are fixed to the bottom of the sliding rod.

[0011] As a further description of the above technical solution: A positioning post is fixed to one side of the extension block, and an extrusion plate is fixed to the bottom of the sliding rod. A first spring that contacts the extrusion plate is sleeved on the outer periphery of the positioning post.

[0012] As a further description of the above technical solution: A connecting plate is fixed on the base, and an extension cylinder is fixed on the side of the connecting plate near the extension block. A rotating rod is rotatably connected to the inner wall of the extension cylinder, and several second gear teeth that mesh with the first gear teeth are connected to the outer periphery of the rotating rod.

[0013] As a further description of the above technical solution: The outer periphery of the extension tube is provided with a limiting groove, and the outer periphery of the rotating rod is fixed with a snap-fit ​​rod that contacts the limiting groove. The inner wall of the snap-fit ​​rod is provided with an inner cavity, and the inner wall of the inner cavity is slidably connected with a buffer column that contacts the photovoltaic tile. A second spring is connected between the buffer column and the inner cavity.

[0014] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: With the addition of a flipping component, a pushing component, and a buffer component, the photovoltaic tiles on the rotating plate can be flipped downwards by a servo motor when encountering hail. Multiple rotating plates are arranged in a descending step-like manner to protect the photovoltaic tiles from hail impacts, and the hail can slide down the inclined surface to avoid accumulating and affecting the support base. Start the electric push rod to engage the half gear with the double-sided gear belt, start the servo motor in reverse, and the rotating plate swings slightly upward to shake off the accumulated leaves and other debris on the back surface, preventing them from affecting the support of the support base. The rotating gear moves and drives the related components to change the locking rod from a horizontal state to a vertical state. When the rotating plate falls, it contacts the buffer post. The buffering effect of the second spring can reduce damage to the photovoltaic tile and improve the protection effect. Attached Figure Description

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] like Figures 1-10As shown, the present invention provides a building-integrated photovoltaic (BIPV) roof: including several bases 10 mounted on a base plate, and further including a flipping assembly 20 disposed on the bases 10. The flipping assembly 20 includes a support 21 fixed on the bases 10. The support 21 is connected to a rotating plate 221 via an internally rotatably connected rotating shaft 22. Photovoltaic tiles are bonded to the rotating plate 221 with structural adhesive. The surface of the rotating plate 221 undergoes fine pretreatment to enhance its adhesion to the structural adhesive. Subsequently, high-performance silicone structural adhesive is used in a uniform and continuous application method to firmly bond the photovoltaic tiles to the rotating plate 221. This bonding method not only ensures extremely high bonding strength between the photovoltaic tiles and the rotating plate 221, but also effectively resists various stresses from the external environment, such as wind and vibration. An extension frame 23 is fixed to one side of the support 21. A groove 222 is formed on the outer periphery of the rotating shaft 22. A limiting block 223 is slidably connected to the inner wall of the 22. A rotating gear 224 and a half gear 225 are fixed to the outer periphery of the limiting block 223. The number of gears in the half gear 225 is adjusted according to the actual use and is not fixed to half of the full gear. An extension plate 24 and a mounting bracket 25 are fixed to the outer wall of the extension frame 23. A double-sided gear belt 26 that meshes with the rotating gear 224 and the half gear 225 is rotatably connected to the outer wall of the extension frame 23 and the extension plate 24. The inner wall of the double-sided gear belt 26 extends into the extension frame 23 and the extension plate 24. The extension plate 24 has a clearance groove to avoid the gears on the inner wall of the double-sided gear belt 26. A driving component is installed on one side of the mounting bracket 25. The driving component includes a servo motor 251 installed on one side of the mounting bracket 25. The output end of the servo motor 251 passes through the mounting bracket 25 and is connected to the main gear 252. The main gear 252 meshes with the double-sided gear belt 26. In the initial state, the photovoltaic tiles on several rotating plates 221 are as follows: Figure 2 As shown, if the photovoltaic tiles are stacked in sequence and encounter hail in the initial state, and the photovoltaic tiles on the rotating plate 221 remain facing upwards, then the impact of the hail will damage the photovoltaic tiles. Therefore, when encountering hail, the position of the photovoltaic tiles needs to be adjusted so that they face downwards to avoid hail impact. By starting the servo motor 251, the servo motor 251 drives the main gear 252 to rotate together. As the main gear 252 rotates, it drives the double-sided gear belt 26 to rotate. The double-sided gear belt 26 further drives the rotating gear 224 to rotate to the left, and at the same time drives the rotating shaft 22 to rotate. As the rotating shaft 22 rotates, the photovoltaic tiles on one side of the rotating plate 221 flip downwards. At this time, the taller rotating plates 221 are stacked on top of the shorter rotating plates 221, so that the multiple rotating plates 221 are arranged in a descending step-like manner. This arrangement can protect the photovoltaic tiles. At the same time, since the multiple rotating plates 221 are arranged in a descending manner, the falling hail will slide down the inclined rotating plate 221 surface and will not accumulate on the rotating plate 221 surface, thus avoiding problems with the support of the support base 21. When it is necessary to remove the protection of the photovoltaic tile and restore it to normal operation, simply start the servo motor 251 in reverse. The servo motor 251 drives the main gear 252 to rotate in the opposite direction, which in turn drives the double-sided gear belt 26 to rotate. The double-sided gear belt 26 drives the rotating gear 224 to rotate to the right, and at the same time drives the rotating shaft 22 to rotate, so that the photovoltaic tile on one side of the rotating plate 221 flips upward and restores the photovoltaic tile to its normal working state.

[0019] like Figure 1 , Figure 3 , Figure 5 , Figure 6 As shown, the inner wall of the extension frame 23 is provided with a pushing assembly 30. The pushing assembly 30 includes a fixing plate 31 fixed to the inner wall of the extension frame 23 and a ring 34 fixed to the side of the half gear 225 away from the rotating gear 224. An electric push rod 32 is installed on one side of the fixing plate 31. The extension end of the electric push rod 32 is fixedly connected to a pushing plate 33. An inner groove 341 is opened inside the ring 34. The pushing plate 33 is movably embedded in the inner groove 341. When the ring 34 rotates, the pushing plate 33 is still embedded in the inner groove 341 and will not cause obstruction. When encountering hail, not only will hail fall on the back surface of the rotating plate 221, but the wind will also blow leaves and other debris onto the inner surface of the rotating plate 221. The accumulation of leaves and other debris will cause some hail to remain on the back surface of the rotating plate 221 and accumulate further, which may affect the support of the support seat 21. To solve this problem, the electric push rod 32 can be activated, which abuts the push plate 33. Since the push plate 33 is embedded in the ring 34, the push plate 33 will abut the ring 34, thereby causing the ring 34 to drive the half gear 225 and the limiting block 223 to move. As the limiting block 223 moves, the rotating gear 224 will also move synchronously, thereby causing the rotating gear 224 to disengage from the double-sided gear belt 26. As the electric push rod 32 continues to extend, the half gear 225 will mesh with the double-sided gear belt 26. When the half gear 225 meshes with the double-sided gear belt 26, the servo motor 251 is started in reverse. The servo motor 251 drives the main gear 252 to rotate together. As the main gear 252 rotates, it drives the double-sided gear belt 26 to rotate. The double-sided gear belt 26 drives the half gear 225 to rotate to the right. Since the multiple rotating plates 221 are set at an angle, under the influence of their own weight and gravity, the half gear 225 is always in a downward rotation trend. When the double-sided gear belt 26 moves and contacts the downward half gear 225, it will drive the half gear 225 to drive the rotating shaft 22 to rotate. As the rotating shaft 22 rotates, the rotating plate 221 will swing slightly upward, thereby shaking off the accumulated material on the back surface of the rotating plate 221.

[0020] like Figure 1 , Figure 3 , Figure 8 , Figure 9 , Figure 10 As shown, a buffer assembly 40 is provided on the base 10. The buffer assembly 40 includes a snap-fit ​​plate 41 that fixes the inner wall of the base 10. An extension block 42 is fixed to the top of the snap-fit ​​plate 41, and a sliding rod 421 is slidably connected to the inner wall of the extension block 42. A contact plate 422 that contacts the rotating gear 224 is fixed to one side of the sliding rod 421. Several first gear teeth 423 are fixed to the bottom of the sliding rod 421. A positioning post 43 is fixed to one side of the extension block 42. A pressing plate 431 is fixed to the bottom of the sliding rod 421. A first spring 432 that contacts the pressing plate 431 is sleeved on the outer periphery of the positioning post 43. A connecting plate 44 is fixed on the base 10. An extension cylinder 45 is fixed to the side of the connecting plate 44 near the extension block 42. A rotating rod 46 is rotatably connected to the inner wall of the extension cylinder 45, and several second gear teeth 461 that mesh with the first gear teeth 423 are connected to the outer periphery of the rotating rod 46. A limiting groove 451 is opened on the outer periphery of the extension cylinder 45. A snap-fit ​​rod 47 that contacts the limiting groove 451 is fixed to the outer periphery of the rotating rod 46. An inner cavity 471 is opened on the inner wall of the snap-fit ​​rod 47. A buffer column 473 that contacts the photovoltaic tile is slidably connected to the inner wall of the inner cavity 471. The length of each buffer column 473 is adjusted according to different heights. A second spring 472 is connected between the buffer column 473 and the inner cavity 471. During the above operation, as the rotating gear 224 moves, it will synchronously abut against the contact plate 422 and move together. When the contact plate 422 moves, it will drive the sliding rod 421 to move. At this time, several first gear teeth 423 at the bottom of the sliding rod 421 will drive the second gear teeth 461, thereby causing several second gear teeth 461 to drive the rotating rod 46 to rotate inside the extension cylinder 45. Meanwhile, as the sliding rod 421 moves, the pressing plate 431 at its bottom slides along the outer periphery of the positioning post 43 and presses the first spring 432. As the rotating rod 46 rotates, it drives the locking rod 47 to move in the limiting groove 451, causing the locking rod 47 to change from a horizontal state to a vertical state. When the locking rod 47 moves to the vertical state, the rotating plate 221 swings slightly upward and then falls under its own weight and gravity. At this time, the rotating plate 221 will contact the buffer post 473 and cause the buffer post 473 to press the second spring 472. Through the buffering effect of the second spring 472, the fall of the rotating plate 221 can be buffered, reducing damage to the photovoltaic tile and improving the protection effect of the photovoltaic tile. When it is necessary to switch to the full gear state, the electric push rod 32 is activated. The electric push rod 32 pulls the push plate 33. Since the push plate 33 is embedded in the ring 34, it will pull the ring 34, which in turn will drive the half gear 225 and the limiting block 223 to move. As the limiting block 223 moves, the rotating gear 224 will move synchronously, causing the half gear 225 to disengage from the double-sided gear belt 26. As the electric push rod 32 retracts, the rotating gear 224 will mesh with the double-sided gear belt 26. At the same time, as the rotating gear 224 moves, the first spring 432, which is in a compressed state, will rebound and push the compression plate 431 to reset. The compression plate 431 drives the sliding rod 421 to move, so that the first gear 423 drives the second gear 461. The second gear 461 drives the rotating rod 46 to rotate, thereby switching the locking rod 47 from the vertical state back to the horizontal state.

[0021] Working principle: In the initial state, photovoltaic tiles on several rotating plates 221 are stacked in sequence. If hail occurs at this time and the photovoltaic tiles are still facing upwards, the impact of the hail will damage them. Therefore, in hail weather, the position of the photovoltaic tiles needs to be adjusted so that they face downwards to avoid impact. The servo motor 251 is started, which drives the main gear 252 to rotate, and then drives the double-sided gear belt 26 to rotate. The double-sided gear belt 26 drives the rotating gear 224 to rotate to the left, so that the rotating shaft 22 rotates. The photovoltaic tiles on one side of the rotating plate 221 flip downwards, and the taller rotating plates 221 are stacked on the lower rotating plates 221 in a descending step arrangement. This arrangement can protect the photovoltaic tiles and allow the hail to slide down the tilted rotating plates 221, avoiding accumulation and affecting the support of the support base 21. During hailstorms, hailstones fall onto the back of the rotating plate 221, and the wind blows leaves and other debris into its interior. The accumulation of debris causes the hailstones to accumulate further, affecting the support of the support base 21. To solve this problem, the electric push rod 32 is activated, which abuts the push plate 33. Since the push plate 33 is embedded in the ring 34, it will drive the ring 34, the half gear 225, and the limiting block 223 to move, causing the rotating gear 224 to disengage from the double-sided gear belt 26. The electric push rod 32 continues to extend, and the half gear 225 engages with the double-sided gear belt 26, which in turn activates the servo motor 251, causing the main gear 252 to rotate. This drives the double-sided gear belt 26 to rotate, causing the half gear 225 to rotate to the right. Because the rotating plate 221 is tilted, the half gear 225 has a downward rotation tendency. When the double-sided gear belt 26 moves and contacts the half gear 225, it will drive the rotating shaft 22 to rotate, causing the rotating plate 221 to swing slightly upward and shake off the accumulated debris on its back. During operation, the rotating gear 224 moves and abuts against the contact plate 422, causing the sliding rod 421 to move. The first gear 423 at its bottom drives the second gear 461, causing the rotating rod 46 to rotate within the extension cylinder 45. Simultaneously, the movement of the sliding rod 421 causes the pressing plate 431 to slide along the positioning post 43 and press the first spring 432. The rotation of the rotating rod 46 causes the locking rod 47 to move within the limiting groove 451, changing from a horizontal to a vertical state. After the locking rod 47 becomes vertical, the rotating plate 221 swings slightly upward and then falls, contacting the buffer post 473 and pressing the second spring 472. The buffering effect of the second spring 472 can reduce damage to the photovoltaic tiles and improve the protection effect.
