Description

Technical Field

[0001] This invention relates to the field of photovoltaic shading technology, and more specifically, to a green building photovoltaic shading device. Background Technology

[0002] With the continuous integration of building technology and photovoltaic technology, green building has achieved significant development. In particular, the integration of photovoltaic products with building exterior walls, windows, and curtain walls has vast application potential. Photovoltaic shading devices combine shading, power generation, and aesthetics, cleverly integrating photovoltaic modules with shading systems into building design. This satisfies the building's shading needs while achieving effective utilization of solar energy, injecting new vitality into the development of green buildings. However, existing products have shortcomings in integrating shading, power generation, lighting, and ventilation, creating limitations in the application of photovoltaic products on building exterior walls and windows. Most photovoltaic shading devices primarily focus on shading and power generation, neglecting the adjustment of indoor lighting and ventilation. While meeting the requirements of green buildings, this can negatively impact daily life. Therefore, it is necessary to provide a green building photovoltaic shading device to address the problems mentioned in the background. Summary of the Invention

[0003] To achieve the above objectives, the present invention provides the following technical solution: a green building photovoltaic shading device, comprising:

[0004] The window is located on the side of the green building;

[0005] Rotate the component and fix it at the top of the form;

[0006] The limit adjustment components are symmetrically distributed in two sets, and are fixedly installed at both ends of the rotating component respectively;

[0007] Multiple sunshade adjustment devices are arranged in a straight line along the limit adjustment components and are rotatably set between the limit adjustment components.

[0008] A photovoltaic device is provided in correspondence with a shading adjustment device, and is slidably disposed between limit adjustment components, with the photovoltaic device located on the side of the shading adjustment device away from the window.

[0009] Furthermore, preferably, the rotating assembly includes:

[0010] Rotate the shaft, which is located at the top of the window, with both ends fixedly connected to the limit adjustment components on both sides;

[0011] The protective curved surface is fixed to the top of the window frame and located outside the rotating shaft. In other words, the rotating shaft drives the limit adjustment component to rotate, thereby adjusting the angle between the photovoltaic shading device and the window frame. This, in turn, adjusts the overall angle of the photovoltaic device, ensuring sunlight hits it at the optimal angle, thus improving photovoltaic power generation efficiency.

[0012] Furthermore, preferably, the limit adjustment component includes:

[0013] The positioning plate is fixed to one end of the rotating shaft.

[0014] An adjusting slide is fixed to the inside of a positioning plate, and the length of the positioning plate is longer than the length of the adjusting slide.

[0015] An extended slide is slidably disposed within an adjusting slide, and a rotating body is provided on the extended slide, the rotating body being slidably connected to a positioning plate;

[0016] Multiple drive components are arranged in a straight line, corresponding to the sunshade adjustment device, and fixed on the outside of the positioning plate. In other words, under the action of the adjusting slide, the photovoltaic device can slide back and forth between the two adjusting slides. When the photovoltaic device is located in the middle of the shading adjustment device, the driving component can drive the shading adjustment device and the photovoltaic device to rotate synchronously, so that there is a gap between each set of shading adjustment devices and photovoltaic devices. Sunlight shines into the room through the gap. The indoor lighting effect can be adjusted by the rotation angle of each set of shading adjustment devices and photovoltaic devices, as well as the rotation angle of the photovoltaic shading device driven by the rotating component. When the photovoltaic device is located between two adjacent shading adjustment devices, the photovoltaic device can completely block the sunlight. Then, the mutual rotation between the shading adjustment devices can be used to adjust the ventilation of the room. When the rotating component drives the photovoltaic shading device to rotate at a larger angle, allowing some light to shine into the room from the bottom of the window, the extension slide extends. When it moves to the end of the positioning plate, the lower photovoltaic device moves onto the extension slide. Then, the rotating body drives the extension slide to rotate, thereby completely blocking the sunlight that cannot be blocked by the lower photovoltaic device.

[0017] Furthermore, preferably, the driving component includes:

[0018] The drive motor is fixed to the outside of the positioning plate;

[0019] A connecting ring is located inside the positioning plate and fixed to the shaft of the drive motor, and the connecting ring is fixedly connected to the sunshade adjustment device;

[0020] The telescopic shaft, coaxial with the shaft of the drive motor, has a fixed end and an extended end. The fixed end is fixedly connected to the shaft of the drive motor, and the extended end is equipped with an electromagnetic adsorption component. The telescopic shaft corresponds to the side of the photovoltaic device. In other words, when the telescopic shaft extends, fixing the electromagnetic adsorption component to the photovoltaic device, the drive motor drives the shading adjustment device to rotate via the connecting ring, while simultaneously driving the photovoltaic device to rotate via the telescopic shaft, thus adjusting the indoor lighting effect. When the telescopic shaft retracts, it disconnects from the photovoltaic device. The photovoltaic device then slides on the limit adjustment component, and the shading adjustment device rotates independently under the drive motor, allowing for indoor ventilation adjustment, or complete shading and power generation.

[0021] Furthermore, preferably, the shading adjustment device includes:

[0022] The central shaft passes through the bottom of the adjusting slide at both ends and is fixedly connected to the corresponding connecting rings;

[0023] The sunshade panel consists of two rotatable sunshade plates mounted on either side of a central axis, positioned between the window and the photovoltaic device. In other words, driven by a motor, the entire sunshade panel rotates via the central axis. By adjusting the tilt angle between the multiple sunshade plates, the indoor lighting effect is regulated. When the motor stops, the sunshade plates on either side of the central axis can rotate independently, increasing the distance between adjacent sunshade plates and regulating indoor ventilation.

[0024] Furthermore, preferably, the photovoltaic device includes:

[0025] The sliding adjustment block is slidably positioned within the adjustment track.

[0026] The telescopic linkage is located inside the adjusting slide and fixed to the top of the sliding adjusting block;

[0027] The photovoltaic module is rotatably mounted between the two telescopic connecting rods, and its top is rotatably connected to the end of the telescopic connecting rod away from the sliding adjustment block. The lower side is provided with a connection hole.

[0028] A rotating motor is fixed to a telescopic connecting rod, and the shaft of the rotating motor is fixedly connected to the photovoltaic module. That is, driven by the sliding adjustment block, the photovoltaic device slides on the adjustment track, adjusting the position between the photovoltaic device and the shading adjustment device to facilitate switching the working state of the photovoltaic shading device. Under the action of the telescopic connecting rod, the distance between the photovoltaic module and the shading panel can be adjusted. When the telescopic connecting rod extends, the photovoltaic module moves away from the shading panel; when the telescopic connecting rod retracts, the photovoltaic module moves closer to the shading panel. Driven by the rotating motor, the photovoltaic module rotates as a whole, placing the photovoltaic module at the optimal angle to the direct sunlight point, effectively improving photovoltaic power generation efficiency.

[0029] Furthermore, preferably, the sliding adjustment block includes:

[0030] The sliding block body is slidably disposed within the adjusting slide rail;

[0031] A movable connecting shaft is slidably disposed at the center of the sliding block body and rotatably connected to the sliding block body. The two ends of the movable connecting shaft correspond to the telescopic shaft and the connection hole of the photovoltaic module, respectively.

[0032] A compression spring is installed on the inner wall of the sliding block body and is sleeved on the movable connecting shaft. In other words, when the extension end of the telescopic shaft on the drive motor extends, the telescopic shaft pushes the movable connecting shaft to slide within the sliding block body, compressing the compression spring. Simultaneously, the movable connecting shaft engages with the side connection hole of the photovoltaic module. The extension end of the telescopic shaft is fixed to the movable connecting shaft via an electromagnetic adsorption component. Driven by the drive motor, the shading adjustment device rotates via the connecting ring, and the photovoltaic module rotates via the movable connecting shaft. Both the shading adjustment device and the photovoltaic module rotate around the shaft of the drive motor, adjusting the gap between each set of shading adjustment devices and the photovoltaic module, guiding light into the room, and adjusting the indoor lighting. When the extension end of the telescopic shaft on the drive motor retracts, the telescopic shaft disengages from the sliding block body, and the movable connecting shaft resets under the action of the compression spring, disengaging from the side connection hole of the photovoltaic module. At this time, the drive motor can only drive the shading adjustment device to rotate, and the photovoltaic module can move on the limit adjustment component under the action of the sliding adjustment block. The angle of the photovoltaic module is adjusted by the rotating motor to fully collect sunlight.

[0033] Furthermore, preferably, the photovoltaic module includes:

[0034] The curved surface has connecting holes on both sides corresponding to the movable connecting shaft;

[0035] Multiple connectors are arranged in a straight line and are fixedly connected to the concave surface of the arc-shaped surface;

[0036] Adjust the rotating shaft, fix the top of multiple connecting parts, and rotatably connect one end to the telescopic connecting rod, and fix the other end to the shaft of the rotating motor;

[0037] Multiple photovoltaic (PV) modules are linearly arranged and fixed on the concave surface of an arc-shaped surface. When the connecting holes on both sides of the arc-shaped surface are engaged with the movable connecting shaft in the sliding adjustment block, the PV module rotates around the movable connecting shaft under the drive of the drive motor, adjusting the angle of the PV module at the same position. When the connecting holes on both sides of the arc-shaped surface disengage from the movable connecting shaft, the adjustment shaft can be rotated by rotating the motor, which in turn drives the entire PV module to rotate and adjust its overall angle through the connecting parts.

[0038] Compared with the prior art, the beneficial effects of the present invention are:

[0039] In this invention, the angle between the photovoltaic shading device and the window is adjusted by setting a rotating component, so that the photovoltaic module faces the direction of direct sunlight, which is conducive to better absorption of solar energy for power generation. By setting a limit adjustment component, the shading adjustment device and the photovoltaic device are dynamically adjusted, so that the photovoltaic shading device can meet multiple needs such as lighting, power generation, and ventilation. Moreover, with the extension of the slide rail, sunlight is effectively prevented from shining into the room from the bottom of the window as the angle between the photovoltaic shading device and the window increases, which helps to improve the shading effect. The working state of the photovoltaic shading device is changed in real time by switching between the drive component and the rotating motor. Attached Figure Description

[0050] Please see Figures 1-9 In this embodiment of the invention, a green building photovoltaic shading device includes:

[0051] Form 1 is located on the side of the green building;

[0052] Rotate component 2 and fix it to the top of form 1;

[0053] The limit adjustment components 3 are provided in two symmetrical sets, which are fixedly installed at both ends of the rotating component 2 respectively;

[0054] The sunshade adjustment device 4 is provided in multiple ways along the limit adjustment component 3 and is rotatably arranged between the limit adjustment components 3.

[0055] The photovoltaic device 5 is arranged correspondingly to the shading adjustment device 4 and is slidably arranged between the limit adjustment components 3. The photovoltaic device 5 is located on the side of the shading adjustment device 4 away from the window 1.

[0056] In this embodiment, the rotating component 2 includes:

[0057] Rotate the shaft 21, which is rotatably set at the top of the window 1, and its two ends are fixedly connected to the limit adjustment components 3 on both sides respectively;

[0058] The protective arc surface 22 is fixed to the top of the window 1 and located outside the rotating shaft 21. That is, under the action of the rotating shaft 21, the limiting adjustment component 3 is rotated by the rotating shaft 21, thereby adjusting the angle between the photovoltaic shading device and the window 1, and thus driving the photovoltaic device 5 to adjust the angle as a whole, so that the sunlight shines on the photovoltaic device 5 at the best angle, which helps to improve the photovoltaic power generation efficiency.

[0059] In this embodiment, the limit adjustment component 3 includes:

[0060] Positioning plate 31 is fixed to one end of rotating shaft 21;

[0061] The adjusting slide 32 is fixed inside the positioning plate 31, and the length of the positioning plate 31 is longer than the length of the adjusting slide 32.

[0062] An extension slide 33 is slidably disposed within an adjustment slide 32, and a rotating body is provided on the extension slide 33, the rotating body being slidably connected to the positioning plate 31;

[0063] Multiple drive components 34 are linearly distributed and corresponding to the shading adjustment devices 4, fixed to the outside of the positioning plate 31. That is, under the action of the adjustment slides 32, the photovoltaic device 5 can slide back and forth between the two adjustment slides 32. When the photovoltaic device 5 is located in the middle of the shading adjustment device 4, the drive components 34 can simultaneously drive the shading adjustment device 4 and the photovoltaic device 5 to rotate synchronously, creating a gap between each set of shading adjustment devices 4 and photovoltaic devices 5. Sunlight shines into the room through these gaps. The indoor lighting effect can be adjusted by the rotation angle of each set of shading adjustment devices 4 and photovoltaic devices 5, as well as the rotation angle of the photovoltaic shading device driven by the rotating component 2. When the photovoltaic device... When the position of device 5 is located between two adjacent sunshade adjustment devices 4, the sunlight can be completely blocked by the photovoltaic device 5. Then, the ventilation of the room can be adjusted by the mutual rotation between the sunshade adjustment devices 4. When the rotating component 2 drives the photovoltaic sunshade device to rotate at a larger angle, allowing some light to shine into the room from the lower part of the window 1, the extension slide 33 extends out. When it moves to the end of the positioning plate 31, the lower photovoltaic device 5 moves onto the extension slide 33. Then, the rotating body drives the extension slide 33 to rotate, thereby completely blocking the sunlight that cannot be blocked by the lower photovoltaic device 5.

[0064] In this embodiment, the driving component 34 includes:

[0065] The drive motor 341 is fixed on the outside of the positioning plate 31;

[0066] The connecting ring 342 is located inside the positioning plate 31 and fixed on the shaft of the drive motor 341. The connecting ring 342 is also fixedly connected to the sunshade adjustment device 4.

[0067] The telescopic shaft 343 is coaxial with the shaft of the drive motor 341, and has a fixed end and an extended end. The fixed end is fixedly connected to the shaft of the drive motor 341, and the extended end is equipped with an electromagnetic adsorption component. The telescopic shaft 343 corresponds to the side of the photovoltaic device 5. That is, when the telescopic shaft 343 extends, fixing the electromagnetic adsorption component to the photovoltaic device 5, the drive motor 341 drives the shading adjustment device 4 to rotate via the connecting ring 342, and simultaneously drives the photovoltaic device 5 to rotate via the telescopic shaft 343, thereby adjusting the indoor lighting effect. When the telescopic shaft 343 retracts, it disconnects from the photovoltaic device 5. At this time, the photovoltaic device 5 slides on the limit adjustment component 3, and the shading adjustment device 4 rotates independently under the drive of the drive motor 341, thereby adjusting indoor ventilation or performing complete shading and power generation.

[0068] In this embodiment, the shading adjustment device 4 includes:

[0069] The central shaft 41 has two ends that pass through the bottom of the adjusting slide 32 and are fixedly connected to the corresponding connecting ring 342;

[0070] The sunshade panel 42 consists of two sunshade plates rotatably mounted on both sides of the central shaft 41, and the sunshade panel 42 is located between the window 1 and the photovoltaic device 5. That is, driven by the drive motor 341, the sunshade panel 42 rotates as a whole through the central shaft 41. By adjusting the tilt angle between the multiple sunshade panels 42, the indoor lighting effect is adjusted. When the drive motor 341 stops working, the sunshade plates located on both sides of the central shaft 41 can rotate independently on the central shaft 41, increasing the interval between two adjacent sunshade plates and adjusting the indoor ventilation.

[0071] In this embodiment, the photovoltaic device 5 includes:

[0072] The sliding adjustment block 51 is slidably set in the adjustment slide 32;

[0073] The telescopic connecting rod 52 is located inside the adjusting slide 32 and is fixed to the top of the sliding adjusting block 51;

[0074] The photovoltaic module 53 is rotatably mounted between the two telescopic connecting rods 52, and its top is rotatably connected to the end of the telescopic connecting rod 52 away from the sliding adjustment block 51. The lower side is provided with a connection hole.

[0075] A rotating motor 54 is fixed to a telescopic connecting rod 52, and the shaft of the rotating motor 54 is fixedly connected to the photovoltaic module 53. That is, driven by the sliding adjustment block 51, the photovoltaic device 5 slides on the adjustment slide 32, adjusting the position between the photovoltaic device 5 and the shading adjustment device 4 to facilitate switching the working state of the photovoltaic shading device. Under the action of the telescopic connecting rod 52, the distance between the photovoltaic module 53 and the shading panel 42 can be adjusted. When the telescopic connecting rod 52 extends, the photovoltaic module 53 moves away from the shading panel 42; when the telescopic connecting rod 52 retracts, the photovoltaic module 53 moves closer to the shading panel 42. Driven by the rotating motor 54, the photovoltaic module 53 rotates as a whole, so that the photovoltaic module 53 is at the optimal angle to the direct sunlight point, effectively improving the photovoltaic power generation efficiency.

[0076] In this embodiment, the sliding adjustment block 51 includes:

[0077] The sliding block body 511 is slidably disposed within the adjusting slide rail 32;

[0078] The movable connecting shaft 512 is slidably disposed at the center of the sliding block body 511 and rotatably connected to the sliding block body 511. The two ends of the movable connecting shaft 512 correspond to the connecting holes of the telescopic shaft 343 and the photovoltaic module 53, respectively.

[0079] A compression spring 513 is disposed on the inner wall of the sliding block body 511 and sleeved on the movable connecting shaft 512. That is, when the extended end of the telescopic shaft 343 on the drive motor 341 extends, the telescopic shaft 343 pushes the movable connecting shaft 512 to slide within the sliding block body 511, compressing the compression spring 513. Simultaneously, the movable connecting shaft 512 engages with the side connection hole of the photovoltaic module 53, and the extended end of the telescopic shaft 343 is fixed to the movable connecting shaft 512 via an electromagnetic adsorption component. Driven by the drive motor 341, the shading adjustment device 4 rotates via the connecting ring 342, and the photovoltaic module 53 rotates via the movable connecting shaft 512. Both the shading adjustment device 4 and the photovoltaic module 53 rotate simultaneously around the shaft of the drive motor 341, adjusting each set of shading... The gap between the shading adjustment device 4 and the photovoltaic module 53 guides light into the room to adjust the indoor lighting. When the extended end of the telescopic shaft 343 on the drive motor 341 retracts, the telescopic shaft 343 disengages from the sliding block body 511, and then the movable connecting shaft 512 is reset under the action of the compression spring 513. The movable connecting shaft 512 disengages from the side connection hole of the photovoltaic module 53. At this time, the drive motor 341 can only drive the shading adjustment device 4 to rotate. The photovoltaic module 53 can move on the limit adjustment component 3 under the drive of the sliding adjustment block 51, and the angle of the photovoltaic module 53 is adjusted by the action of the rotating motor 54 to fully collect sunlight.

[0080] In this embodiment, the photovoltaic module 53 includes:

[0081] The arc-shaped surface 531 has connecting holes on both sides corresponding to the movable connecting shaft 512;

[0082] Multiple connectors 532 are arranged in a straight line and are fixedly connected to the concave surface of the arc-shaped surface 531;

[0083] Adjust the rotating shaft 533, fix the top of multiple connecting parts 532, and rotatably connect one end to the telescopic connecting rod 52, and fix the other end to the shaft of the rotating motor 54;

[0084] Multiple photovoltaic elements 534 are linearly distributed and fixed on the concave surface of the arc-shaped surface 531. When the connecting holes on both sides of the arc-shaped surface 531 are engaged with the movable connecting shaft 512 in the sliding adjustment block 51, the photovoltaic module 53 rotates around the movable connecting shaft 512 under the drive of the drive motor 341, adjusting the angle of the photovoltaic element 534 at the same position. When the connecting holes on both sides of the arc-shaped surface 531 disengage from the movable connecting shaft 512, the adjustment shaft 533 can be rotated by the rotation motor 54, which in turn drives the photovoltaic module 53 to rotate and adjust the overall angle of the photovoltaic module 53 through the connecting piece 532.

[0085] In specific implementation, firstly, during rainy weather when protection of the photovoltaic device 5 is needed, the rotating component 2 drives the limit adjustment component 3 to rotate via the rotating shaft 21, causing the limit adjustment component 3 to fit against the window 1. Then, the telescopic connecting rod 52 in the photovoltaic device 5 extends, moving the photovoltaic component 53 away from the sunshade panel 42. Next, the rotating motor 54 drives the photovoltaic component 53 to rotate 180°, so that the photovoltaic component 534 faces the sunshade panel 42. Then, the telescopic connecting rod 52 retracts, and the sunshade panel 42 and the curved surface 531 protect the photovoltaic component 534, reducing its wear and tear. Secondly, in the morning or evening when the sunlight is soft and indoor lighting is needed, at this time... By rotating the shaft 21, the limiting adjustment component 3 is driven to rotate, adjusting the angle between the limiting adjustment component 3 and the window 1, that is, adjusting the angle between the shading adjustment device 4 and the photovoltaic device 5. Then, the telescopic shaft 343 on the drive motor 341 extends, and the telescopic shaft 343 pushes the movable connecting shaft 512 to slide within the sliding block body 511, compressing the compression spring 513. At the same time, the movable connecting shaft 512 is engaged in the side connection hole of the photovoltaic module 53, and the extended end of the telescopic shaft 343 is fixed together with the movable connecting shaft 512 by an electromagnetic adsorption component. Under the drive of the drive motor 341, the shading adjustment device 4 and the photovoltaic module 53 move simultaneously. The telescopic shaft 343 rotates around the central axis to adjust the gap between each set of shading adjustment devices 4 and photovoltaic modules 53, guiding light into the room and adjusting indoor lighting. When photovoltaic power generation is in operation and indoor ventilation is required, the telescopic shaft 343 retracts, causing the movable connecting shaft 512 to reset under the action of the compression spring 513. The movable connecting shaft 512 disengages from the side connection hole of the photovoltaic module 53, and then slides on the adjusting slide 32 through the sliding adjustment block 51, causing the photovoltaic module 53 to slide to the position between two adjacent shading adjustment devices 4. Then, the telescopic connecting rod 52 extends, moving the photovoltaic module 53 away from the shading panel 42 to meet the shading surface requirements. The panel 42 can be rotated, and then the entire sunshade panel 42 can be rotated by the drive motor 341, or the two sunshade panels can rotate on the central axis 41. While the photovoltaic device 5 blocks the sunlight, airflow is allowed between the sunshade panels 42 to regulate indoor ventilation. It should be noted that if the limit adjustment component 3 tilts too much, causing some light to enter the room from the bottom of the window 1, the extension slide 33 will extend. When it moves to the end of the positioning plate 31, the lower photovoltaic device 5 moves onto the extension slide 33. Then, the extension slide 33 is rotated by the rotating body, and the lower photovoltaic device 5 completely blocks the sunlight that has not been blocked.During photovoltaic power generation, the shading adjustment device 4 and photovoltaic module 53 can rotate simultaneously. Under the rotation adjustment of the limit adjustment component 3, multiple sets of shading adjustment devices 4 and photovoltaic modules 53 can mutually block sunlight from directly entering the room, ensuring the photovoltaic module 534 reaches the optimal angle with sunlight and improving light energy conversion efficiency. Alternatively, the rotating motor 54 can directly drive the photovoltaic module 53 to rotate, adjusting the position between the photovoltaic module 534 and the angle with sunlight. In this case, the shading adjustment device 4 can be in a sealed state, or its rotation can be adjusted according to the position of the photovoltaic module 53 on the adjustment slide 32.
