Description

Technical Field

[0001] This application relates to the technical field of photovoltaic sunshade curtain walls, and particularly to a photovoltaic sunshade curtain wall structure with vertical two-degree-of-freedom adjustment. Background Technique

[0002] At present, as a non-load-bearing exterior wall enclosure of buildings, curtain walls are widely used in modern large-scale and high-rise buildings due to their light weight and strong decorative properties. As a component used in conjunction with curtain walls, photovoltaic sunshade panels can not only play a sunshading role but also achieve electric energy conversion through photovoltaic modules, becoming an important functional component in the curtain wall system. However, the photovoltaic sunshade panels supporting existing curtain walls generally have problems of inconvenient rotation and difficult operation, making it difficult to flexibly adjust the angle according to actual usage requirements, affecting the optimization of sunshading effects and electric energy conversion efficiency, and limiting their adaptability in different scenarios. To improve this situation, Chinese Patent No. CN202866614U with the publication number discloses a curtain wall photovoltaic sunshade panel. This solution includes a frame, a photovoltaic sunshade panel, a push rod motor, a light sensor, and a single-chip microcomputer. At least one rotatable photovoltaic sunshade panel is hinged at intervals from top to bottom within the frame. The push rod of the push rod motor is connected to each photovoltaic sunshade panel. The light sensor fixed on the frame transmits signals to the single-chip microcomputer through wires, and the single-chip microcomputer then controls the switch of the push rod motor through wires. At the same time, a photovoltaic thin film battery is fixed on the photovoltaic sunshade panel, and the push rod motor can be powered by the photovoltaic thin film battery to achieve automatic control based on light, improving the operation convenience and work efficiency to a certain extent. However, in actual applications, this patent solution still has obvious defects and deficiencies. Firstly, the angle adjustment range is limited. The solution uses a push rod to adjust the rotation of the louver-type photovoltaic sunshade panel. Limited by the telescopic stroke of the push rod and the hinge structure, the rotation angle of the photovoltaic sunshade panel cannot be adjusted within a large range. Especially in windy weather, it is impossible to rotate each louver photovoltaic panel to a vertical state to reduce the impact of wind load on the photovoltaic panel, easily leading to component damage or reduced stability. Secondly, cleaning and maintenance are difficult. Since photovoltaic sunshade panels are usually installed in high-altitude outdoor environments, impurities such as dust and slag in the air are easily attached to the outer surface of the photovoltaic louver panels. Long-term accumulation will significantly affect the light transmittance and electric energy conversion efficiency of the photovoltaic modules. Manual cleaning of the high-altitude louver photovoltaic panels is not only cumbersome and inconvenient to operate but also poses a high safety risk, making it difficult to ensure the cleaning requirements and electric energy conversion effects during long-term use. The existence of these problems indicates that there is still much room for improvement in the functional integrity and practicality of existing curtain wall photovoltaic sunshade panels.

[0017] The following is in conjunction with the appendix Figure 1-9 This application will be described in further detail.

[0018] This application discloses a vertically adjustable photovoltaic shading curtain wall structure with two degrees of freedom. For example... Figure 1-9 As shown, it includes a curtain wall frame 1, a high heat insulation glass curtain wall 2 fixedly installed on the inner side of the curtain wall frame 1, a support rail frame 4 fixedly installed at the four corners of the front of the curtain wall frame 1, a photovoltaic mechanism 3 fixedly installed at the front end of the support rail frame 4, a drive mechanism 5 fixedly installed on one side of the photovoltaic mechanism 3, and an anti-shading cleaning mechanism 6 slidably connected to the inner side of each support rail frame 4. The lower end of the anti-shading cleaning mechanism 6 is connected to the drive mechanism 5 through a transmission. The photovoltaic mechanism 3 includes a main frame 31, which is fixedly installed at the front end of the support rail 4. Rotating shafts 32 are linearly arranged at equal intervals inside the main frame 31 and are rotatably connected to it. Photovoltaic modules 33 are fixedly connected to the outer surface of the rotating shafts 32. The outer ends of each rotating shaft 32 are connected to the output end of the drive mechanism 5. During application, this device, through the arrangement of the curtain wall frame 1, high-insulation glass curtain wall 2, support rail 4, photovoltaic mechanism 3, drive mechanism 5, and anti-shading cleaning mechanism 6, allows the curtain wall frame 1 to provide an overall installation foundation. The high-insulation glass curtain wall 2 on the inner side provides building insulation, and the support rails 4 at the four corners of the front provide stable support for the photovoltaic mechanism 3 and a sliding path for the anti-shading cleaning mechanism 6. When it is necessary to adjust the position or angle of the photovoltaic modules 33, the drive mechanism 5... The rotating shafts 32, which are arranged at equal intervals inside the photovoltaic mechanism 3, can rotate, thereby causing the photovoltaic modules 33 on the outer surface to adjust their state to adapt to different shading or power generation needs. The anti-shading cleaning mechanism 6 can slide inside the support rail frame 4 and, through transmission cooperation with the drive mechanism 5, can move to the vicinity of the photovoltaic modules 33 when needed to reduce shading and assist in maintenance. This design allows the device to have both basic curtain wall heat insulation function and to realize power conversion through the photovoltaic mechanism 3. The cooperation between the drive mechanism 5 and the anti-shading cleaning mechanism 6 can also improve the flexibility of use and the convenience of maintenance of the photovoltaic modules 33, effectively solving the problems of single function and inconvenient module adjustment in some existing photovoltaic shading curtain walls. It takes into account both practicality and functionality, and meets the multiple needs of buildings for heat insulation, shading and energy utilization.

[0019] Please refer to Figures 1-6 and Figure 9The photovoltaic module 33 includes a louvered plate 331, which is fixedly installed on the outer surface of the rotating shaft 32. A photovoltaic panel 332 is fixedly connected to one side of the louvered plate 331. Wind-resistant guide grooves 333 are provided on both sides of the louvered plate 331, forming a streamlined triangle at both ends through the wind-resistant guide grooves 333. An anti-stick coating is provided on the outer surface of the photovoltaic panel 332, which is a composite coating of nano-TiO2 and hydrophobic resin. During application, the photovoltaic module 33, composed of the louvered plate 331 and the photovoltaic panel 332, along with the wind-resistant guide grooves 333 on both sides of the louvered plate 331 and the composite anti-stick coating of nano-TiO2 and hydrophobic resin on the outer surface of the photovoltaic panel 332, ensures that when the drive mechanism 5 rotates the rotating shaft 32, the rotating shaft 32 drives the louvered plate 331 on the outer surface to rotate synchronously, allowing the light from one side of the louvered plate 331 to pass through. The photovoltaic panel 332 adjusts its orientation accordingly to adapt to different shading needs and allow the photovoltaic panel 332 to better receive sunlight, thereby improving the power conversion efficiency. At the same time, the wind-resistant guide grooves 333 on both sides of the louvered panel 331 form a streamlined triangle, which can reduce the impact of airflow on the louvered panel 331 and improve the stability of the device in windy environments. The composite anti-stick coating on the outer surface of the photovoltaic panel 332 can reduce the adhesion of dust, slag and other impurities to the surface of the photovoltaic panel 332, reduce the impact of impurities on light absorption, and make subsequent cleaning easier. This design allows the photovoltaic module 33 to achieve shading and power generation functions while taking into account wind resistance stability and the cleanliness maintenance of the photovoltaic panel 332. It effectively solves the problems of poor wind resistance of some photovoltaic modules 33 and easy dust accumulation in photovoltaic panels 332 that affect efficiency in the existing technology, improves the durability and practicality of the device in outdoor environments, and meets the functional requirements of long-term use of buildings.

[0020] Please refer to Figures 1-6 and Figure 8The drive mechanism 5 includes a side plate 51 and worm gears 52. The side plate 51 is fixedly installed on the top and bottom of one side of the main frame 31. The worm gears 52 are linearly arranged at equal intervals and rotatably connected to the side of the main frame 31 near the side plate 51. The inner side of the worm gears 52 is fixedly connected to the outer end of the rotating shaft 32. A first motor 53 is fixedly connected to the top of the top side plate 51. The output end of the first motor 53 passes through the side plate 51 and is fixedly installed with a worm 54. The worm 54 is rotatably connected to the inner side of the two side plates 51. The rod 54 and the worm gear 52 are connected by a transmission. A cover shell 55 is fixedly installed on the outside of the main frame 31, covering the outer surface of the worm gear 52 and the worm 54. During the application of this device, a drive mechanism 5 consisting of a side plate 51, a worm gear 52, a first motor 53, a worm 54, and a cover shell 55 is set up so that when it is necessary to adjust the state of the photovoltaic module 33, the first motor 53 on the top side plate 51 can be started. The output end of the first motor 53 passes through the side plate 51 and drives the worm. When rod 54 rotates, worm gear 54 and worm wheels 52 arranged at equal intervals on one side of main frame 31 form a transmission engagement, thereby driving worm wheels 52 to rotate synchronously. The inner side of worm wheel 52 is connected to the outer end of rotating shaft 32. The rotation of worm wheel 52 will drive rotating shaft 32 to rotate accordingly, ultimately realizing the angle or position adjustment of photovoltaic module 33 to adapt to different shading and power generation needs. At the same time, the outer shell 55 covering the outer surface of worm wheel 52 and worm gear 54 can prevent outdoor dust, rainwater and other impurities from contacting the transmission components, reducing the interference of impurities on the transmission process. This design allows drive mechanism 5 to stably drive photovoltaic module 33 for adjustment. The transmission of worm gear 54 and worm wheel 52 ensures the accuracy and synchronization of the adjustment process, while the outer shell 55 extends the service life of transmission components. It effectively solves the problems of insufficient adjustment stability of some drive mechanisms 5 and easy influence of outdoor environment on transmission components in the prior art, improves the overall durability and adjustment reliability of the device, and meets the needs of long-term outdoor use.

[0021] Please refer to Figures 1-7The anti-obstruction cleaning mechanism 6 includes a transmission module 61 and a slider 62. The transmission module 61 is located on the side of the main frame 31 near the drive mechanism 5. The slider 62 is slidably connected to the inside of the support rail frame 4. A mounting main frame 63 is fixedly installed on the inner side of the slider 62. A cleaning module 64 is fixedly installed in the middle of the mounting main frame 63. The cleaning module 64 includes a guide rail 641, which is fixedly installed in the middle of the side of the mounting main frame 63 near the main frame 31. A lead screw 642 is rotatably connected inside the guide rail 641. A bellows cover is provided on the outside of the guide rail 641 and covers the outside of the lead screw 642. A second [unclear - possibly a device or mechanism] is fixedly connected to one end of the guide rail 641. The output end of the second motor 643 is fixedly connected to one end of the lead screw 642. A sliding block 644 is threaded onto the outer surface of the lead screw 642. The sliding block 644 is slidably connected to the inside of the guide rail 641. A cleaning brush plate 645 is fixedly installed on the side of the sliding block 644 near the main frame 31. After the cleaning soft brush end of the cleaning brush plate 645 moves forward, it is in contact with the outer surface of the flipped photovoltaic panel 332. During the application of this device, by setting up an anti-shading cleaning mechanism 6 composed of a transmission module 61, a slider 62, a mounting main frame 63, and a cleaning module 64, it ensures that when cleaning of the photovoltaic panel 332 is required, the transmission module... 61 can drive the slider 62 to move inside the support rail frame 4. The slider 62 then drives the inner mounting main frame 63 to move synchronously. The cleaning module 64 in the middle of the mounting main frame 63 adjusts its position until it corresponds to the flipped photovoltaic panel 332. Then, the second motor 643 at one end of the guide rail 641 of the cleaning module 64 is activated. The output end of the second motor 643 drives the lead screw 642 inside the guide rail 641 to rotate. The sliding block 644, which is threaded on the outer surface of the lead screw 642, slides along the inner side of the guide rail 641. The cleaning brush plate 645 on the side of the sliding block 644 near the main frame 31 moves synchronously, so that the cleaning soft brush end of the cleaning brush plate 645 is aligned with the flipped photovoltaic panel 332. The outer surface of the photovoltaic panel 332 is bonded to facilitate cleaning. Simultaneously, the bellows cover on the outside of the guide rail 641 covers the outer surface of the lead screw 642, preventing impurities from entering the guide rail 641 and affecting the operation of the lead screw 642. This design allows the anti-shading cleaning mechanism 6 to adjust its cleaning position by moving and to precisely clean the photovoltaic panel 332 through the cleaning module 64, avoiding impurities from obstructing the photovoltaic panel 332 and affecting its efficiency. This effectively solves the problems of inconvenient cleaning and reduced functionality due to obstruction in some existing photovoltaic curtain walls, improving the convenience of photovoltaic panel 332 maintenance and the long-term stability of the device, and meeting the cleaning needs in outdoor environments.

[0022] Please refer to Figures 1-8The transmission module 61 includes a connecting side frame 611 and a power gear 612. The power gear 612 is rotatably connected to the side of the bottom side plate 51 away from the worm gear 54. The connecting side frame 611 is fixedly installed on the outer side of the slider 62 closest to the power gear 612 among the four sliders 62. A power rack 613 is fixedly installed on the outer side of the side frame, and the power rack 613 and the power gear 612 are meshed together. A protective shell 614 is fixedly installed on the lower end of the main frame 31 near the worm gear 54 and the worm wheel 52, and the protective shell 614 covers the gear and rack. On the outside, the connecting side frame 611 and the protective shell 614 are slidably connected. The outer surfaces of the guide rail 641, support rail frame 4, protective shell 614, main frame 31 and covering shell 55 are all coated with anodized polytetrafluoroethylene. During the application of this device, by setting up a transmission module 61 consisting of connecting side frame 611, power gear 612 and power rack 613, as well as the protective shell 614 and anodized polytetrafluoroethylene coating, when it is necessary to drive the anti-obstruction cleaning mechanism 6 to move, the rotation of the power gear 612 will mesh with the power rack 613 to transmit power. The drive rack 613 is fixed to the outside of the connecting side frame 611, which is connected to the slider 62. This drives the slider 62 to move within the support rail frame 4, thus adjusting the position of the anti-shading cleaning mechanism 6 to meet the cleaning needs of photovoltaic panels 332 in different locations. Simultaneously, the protective shell 614 at the lower end of the main frame 31 covers the gears and rack, preventing outdoor dust, rainwater, and other impurities from contacting the transmission components and avoiding interference with transmission smoothness. The connecting side frame 611 can slide within the protective shell 614 without affecting the transmission process. Furthermore, the guide rail 641 and support rail... The anodized polytetrafluoroethylene coating on the outer surfaces of the frame 4, protective shell 614, main frame 31, and covering shell 55 enhances the corrosion resistance and wear resistance of these structures, reducing the erosion of the structure by the outdoor environment. This design allows the transmission module 61 to stably drive the cleaning mechanism to move. The protective shell 614 and coating extend the service life of the transmission components and the overall structure, effectively solving the problem that some transmission structures in the prior art are easily affected by the outdoor environment and have a short service life. This improves the reliability of the device's transmission and its durability for long-term use, ensuring the stable realization of the cleaning function.

[0023] The implementation principle of a vertically adjustable photovoltaic shading curtain wall structure according to an embodiment of this application is as follows: During application, a PLC controller or microcontroller controller is first installed at the building, along with a wind sensor. Then, the controller is electrically connected to the first motor 53 and the second motor 643 of this device, thus completing the control link setup before equipment startup. When the angle of the photovoltaic module 33 needs to be adjusted, the controller sends a signal to start the first motor 53 of the drive mechanism 5. The output end of the first motor 53 passes through the side plate 51 and drives the worm gear 54 to rotate. The worm gear 54 and the worm wheels 52 arranged at equal intervals form a transmission engagement. The worm wheels 52 then drive the rotating shaft 32 to rotate inside the main frame 31. A louvered plate 331 is fixed to the outer surface of the rotating shaft 32, and a louvered plate 331 is fixed to one side of the louvered plate 331. The photovoltaic panel 332 adjusts its angle synchronously with the rotating shaft 32 to adapt to different shading or power generation needs. If the wind sensor detects strong winds, the controller will immediately send a signal to control the first motor 53 to drive the worm gear 54, worm wheel 52 and rotating shaft 32 to rotate, so that the louvered plate 331 rotates to a suitable angle to reduce wind load. At this time, the wind-resistant guide grooves 333 opened on both sides of the louvered plate 331 will form a streamlined triangle to reduce the impact of airflow on the structure. At the same time, during the process of adjusting the angle through the transmission of the worm gear 54 and worm wheel 52, the power gear 612 will also be driven to rotate synchronously, preparing for the subsequent movement of the cleaning mechanism. During use, the photovoltaic panel 332 can be cleaned on rainy days. When the surface of the photovoltaic panel 332 is wetted by rainwater, the nano-TiO2 and hydrophobic resin composite anti-stick coating on the outer surface of the photovoltaic panel 332 effectively reduces the adhesion of dust, slag, and other impurities, reducing cleaning resistance. When cleaning of the photovoltaic panel 332 is required, the controller continues to drive the worm gear 54 and worm wheel 52 via the first motor 53, causing the photovoltaic panel 332 to gradually rotate to the rear and parallel to the curtain wall frame 1. During this process, the transmission of the worm gear 54 and worm wheel 52 drives the power gear 61 of the transmission module 61. 2. When the power gear 612 rotates, it meshes with the power rack 613 fixed on the outside of the connecting side frame 611, thereby driving the power rack 613 to move forward in the horizontal direction. The connecting side frame 611 then drives the slider 62 to move forward along the inside of the support rail frame 4. The mounting main frame 63 fixed on the inside of the slider 62 and the cleaning module 64 fixed in the middle of the mounting main frame 63 will also move forward synchronously with the mounting main frame 63. When the photovoltaic panel 332 rotates to the rear side and is in a parallel and collinear state with the curtain wall frame 1, the cleaning module 64 moves to the corresponding position of the photovoltaic panel 332, and the cleaning brush plate is in contact with the surface of the photovoltaic panel 332. When the slider 62 moves the cleaning module 64 to the designated position, the cleaning brush 645 is in contact with the outer surface of the photovoltaic panel 332 that is flipped to the rear. At this time, the controller sends a signal to start the second motor 643 of the cleaning module 64. The output of the second motor 643 drives the lead screw 642 inside the guide rail 641 to rotate. The sliding block 644, which is threaded to the outer surface of the lead screw 642, slides along the inner side of the guide rail 641. The cleaning brush 645, which is fixed to the side of the sliding block 644 near the main frame 31, moves synchronously with the sliding block 644 to thoroughly clean the surface of the photovoltaic panel 332. In addition, the bellows cover set on the outside of the guide rail 641 covers the outside of the lead screw 642 to prevent impurities from entering the inside of the guide rail 641 during the cleaning process. The operation of the lead screw 642 is affected. Throughout the entire use, the support rails 4 fixed at the four corners of the front of the curtain wall frame 1 provide a stable installation foundation for the photovoltaic mechanism 3. The main frame 31 of the photovoltaic mechanism 3 provides rotational support for the rotating shaft 32. The outer shell 55 fixed to the outside of the main frame 31 covers the outer surface of the worm gear 52 and the worm 54. The protective shell 614 fixed to the lower end of the main frame 31 near the worm 54 and the worm gear 52 covers the outer surface of the power gear 612 and the power rack 613 to prevent outdoor impurities from affecting the operation of the transmission components. The outer surfaces of the guide rail 641, the support rail 4, the protective shell 614, the main frame 31, and the outer shell 55 are all coated with anodized polytetrafluoroethylene to improve the corrosion resistance of each structure. This technical solution, through the worm gear 54 and worm wheel 52 transmission structure, not only enables the photovoltaic module 33 to achieve a wider range of angle adjustment to meet different shading and power generation needs, but also drives the power gear 612 to move the cleaning mechanism forward. Combined with the linkage of the wind sensor and controller, it can quickly adjust the angle of the louvers 331 to reduce wind resistance, solving the problems of limited angle adjustment range and poor wind resistance of photovoltaic sunshades in the prior art. At the same time, by linking the worm gear 54 and worm wheel 52 transmission with the forward movement of the cleaning mechanism, the cleaning brush 645 can accurately fit with the flipped photovoltaic panel 332, achieving automatic cleaning in conjunction with the cleaning module 64, eliminating the need for manual high-altitude operation. By combining the anti-stick coating of the photovoltaic panel 332 with the opportunity to clean it in rainy weather, impurities are efficiently removed, ensuring the light transmittance and power conversion efficiency of the photovoltaic panel 332. This solves the problems of difficult cleaning and maintenance of the photovoltaic panel 332 and the impact on power conversion efficiency in the prior art. In addition, by combining the high heat insulation glass curtain wall 2 with the photovoltaic mechanism 3, and simultaneously setting the outer shell 55, the protective shell 614 and the anodized polytetrafluoroethylene coating, the device can take into account both heat insulation and power generation functions, extend the service life of the equipment, and the linkage adjustment between the photovoltaic module 33 and the cleaning mechanism also improves the structural adaptability, solves the problems of single structural function and insufficient practicality in the prior art, and meets the usage needs in different environments. During application, the transmission ratio can be adjusted by changing the specifications of the worm gear 52 and worm 54 as needed. Additionally, a gear transmission assembly (gearbox) can be set up to change the transmission ratio of the worm gear 54 and worm wheel 52 driving the shaft 32. Specific applications can be flexibly selected and adapted according to requirements. When changing the specifications of the worm gear 52, increasing the number of teeth increases the transmission ratio, and the angle at which the worm wheel 52 rotates per revolution of the worm 54 decreases; conversely, decreasing the number of teeth decreases the transmission ratio, and the rotation angle of the worm wheel 52 increases. When changing the specifications of the worm 54, increasing the number of threads (e.g., changing from single-threaded to double-threaded) decreases the transmission ratio, and the rotation angle of the worm wheel 52 increases accordingly; conversely, decreasing the number of threads increases the transmission ratio, and the rotation angle of the worm wheel 52 decreases. Furthermore, under the premise of the same module, the rotation angle of the worm wheel 52 can be adjusted by changing the number of teeth of the worm 54 or the worm wheel 52 (without changing the module). During use, the cleaning plate can be replaced with a silicone scraper or a wiping plate or other cleaning structures as needed. It is not limited to brush cleaning. The specific application can be flexibly selected according to actual needs.

[0024] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
