Description

Technical Field

[0001] This utility model relates to the field of photovoltaic window technology, and in particular to a photovoltaic window. Background Technology

[0002] Photovoltaic windows are a type of building-integrated photovoltaics (BIPV), an innovative device that combines solar photovoltaic power generation technology with architectural window design. They use semi-transparent photovoltaic modules encapsulated in double-glazed glass to replace traditional glass, forming a window system typically composed of photovoltaic modules and a window frame. Based on the photovoltaic effect, when sunlight shines on photovoltaic materials, electrons in the material are excited and jump to the conduction band, thereby generating electricity. These windows are usually composed of multiple layers of special materials, including at least one layer of transparent conductive oxide (TCO), photovoltaic cells, an anti-reflective coating, and encapsulation materials. Photovoltaic windows can directly convert solar energy into electrical energy, reducing the consumption of traditional energy sources and minimizing environmental pollution.

[0003] However, because the angle at which sunlight hits a window changes throughout the day, most photovoltaic (PV) windows are equipped with brackets to adjust their angle in order to better adapt to these changes. These brackets often require manual adjustment, meaning the PV window cannot always be at its optimal angle.

[0004] The technical content disclosed in the Chinese patent document (publication number: CN109750946A, patent name: A photovoltaic window) is as follows: a bracket connected to a photovoltaic window sash can be set on the window frame. The bracket enables the photovoltaic window sash to move up and down on the window frame. Moreover, the bracket can adjust the tilt angle of the photovoltaic window sash so that sunlight can shine on the photovoltaic window sash as vertically as possible, thereby improving the output power of the photovoltaic window sash.

[0005] As can be seen from the above implementation plan and the corresponding drawings, the photovoltaic window has a bracket on the window frame that is connected to the photovoltaic window sash. The bracket is used to adjust the tilt angle of the photovoltaic window sash so that sunlight can shine on the photovoltaic window sash as perpendicularly as possible. However, this manual adjustment setting is too dependent on people, so it cannot make the photovoltaic window always in the optimal angle setting state. Utility Model Content

[0006] This utility model overcomes the shortcomings of the prior art and provides a photovoltaic window. Through the combined use of a drive device and a linkage rod, several photovoltaic modules can be synchronously and accurately adjusted to the optimal angle under different lighting conditions, effectively improving the absorption efficiency of solar energy and thus enhancing the power generation efficiency.

[0007] To solve the above-mentioned technical problems, the utility model is implemented through the following technical solution:

[0008] A photovoltaic window includes a window frame with several photovoltaic panel frames rotatably connected to the window frame. A photovoltaic module is disposed at the center of each photovoltaic panel frame. The window frame is also provided with a driving device, which is connected to an active rotating shaft. The active rotating shaft is coaxially fixedly connected to one side of one of the photovoltaic panel frames. When the driving device is started and drives the active rotating shaft to rotate, the photovoltaic panel frame connected to it will rotate around the window frame.

[0009] The remaining photovoltaic panel frames are connected to auxiliary pivots, which allow these remaining photovoltaic panel frames to be rotatably connected to the window frame.

[0010] All the photovoltaic panel frames are connected to the linkage rods, so when one photovoltaic panel frame rotates along the window frame and opens or closes, the other photovoltaic panel frames will rotate and open or close synchronously under the action of the linkage rods.

[0011] Furthermore, the photovoltaic module is a bifacial double-glass module.

[0012] Furthermore, a temperature detector is installed on the frame of the photovoltaic panel, which collects the current component temperature and feeds it back to the backend.

[0013] Furthermore, a second bearing is provided at the connection point between the photovoltaic panel frame and the linkage rod, and bearing washers are also provided on the upper and lower sides of the second bearing.

[0014] Furthermore, the photovoltaic panel frame, linkage rod, and second bearing are connected by a bolt and nut assembly.

[0015] Furthermore, the active rotating shaft is connected to the window frame via a first bearing.

[0016] Furthermore, both the first and second bearings are ball bearings.

[0017] Furthermore, the window frame is provided with a linkage fitting groove. When the photovoltaic panel frame is in a closed state, the linkage rod is fitted in the linkage fitting groove. The side wall of the linkage fitting groove limits the linkage rod, so that the photovoltaic panel frame support opens towards the side of the window frame.

[0018] Furthermore, the lower edge of the photovoltaic panel frame is connected to a limiting component, and the other end of the limiting component is connected to the window frame.

[0019] Furthermore, the photovoltaic window is also equipped with a solar tracking system, which can monitor the position of the sun in real time and automatically adjust the angle of the photovoltaic panel frame through a drive device so that the photovoltaic module always maintains an angle perpendicular to the sunlight.

[0020] Compared with existing technologies, the advantages of this utility model are:

[0021] 1. By using the drive device and linkage rod in combination, several photovoltaic modules can be synchronously and accurately adjusted to the optimal angle under different lighting conditions, which effectively improves the absorption efficiency of solar energy and thus improves the power generation efficiency.

[0022] 2. Temperature detectors are installed on the frame of the photovoltaic panels. These detectors can collect the current temperature of the photovoltaic modules and feed the data back to the backend, allowing staff to monitor the temperature status of the photovoltaic modules in real time. Since temperature has a significant impact on the power generation efficiency of photovoltaic modules, excessively high temperatures can cause performance degradation. The temperature detectors can assist the backend control system in taking timely measures to ensure that the photovoltaic modules operate at a suitable temperature, thereby improving power generation efficiency, avoiding performance fluctuations caused by excessively high temperatures, enhancing the stability of photovoltaic window operation, and improving the overall intelligence level of the photovoltaic window.

[0031] The preferred embodiments of the utility model are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the utility model.

[0032] like Figures 1 to 6 As shown, a photovoltaic window includes a window frame 1, with several photovoltaic panel frames 6 rotatably connected to the window frame 1. A photovoltaic module 5 is disposed at the center of each photovoltaic panel frame 6. A driving device 9 is also disposed on the window frame 1. In this embodiment, the driving device 9 is a motor, and its output end is connected to a drive shaft 7. The drive shaft 7 is coaxially fixedly connected to one side of one of the photovoltaic panel frames 6. When the driving device 9 starts and drives the drive shaft 7 to rotate, the photovoltaic panel frame 6 connected to it will rotate around the window frame 1. The remaining photovoltaic panel frames 6 are respectively connected to auxiliary shafts 8. With the help of the auxiliary shafts 8, these auxiliary shafts... The photovoltaic panel frame 6 can also form a rotatable connection with the window frame 1. All photovoltaic panel frames 6 are connected to the linkage rod 4. Therefore, when one photovoltaic panel frame 6 rotates along the window frame 1 and opens or closes, the other photovoltaic panel frames 6 will rotate and open and close synchronously under the action of the linkage rod 4. The photovoltaic window is also equipped with a solar tracking system, which can monitor the position of the sun in real time and automatically adjust the angle of the photovoltaic panel frame 6 through the drive device 9 so that the photovoltaic module 5 always maintains an angle perpendicular to the sunlight. All components cooperate with each other to achieve efficient operation and intelligent control of the photovoltaic window.

[0033] The window frame 1 is made of high-strength, corrosion-resistant aluminum alloy, capable of bearing the weight of the photovoltaic panel frame 6 and the photovoltaic module 5, while resisting external environmental erosion, ensuring the long-term stability and safety of the photovoltaic window. The photovoltaic panel frame 6 surrounds the photovoltaic module 5, not only fixing the photovoltaic module 5 but also providing necessary protection. It prevents the photovoltaic module 5 from being impacted and damaged by external forces, and has good sealing properties, effectively preventing moisture and dust from entering the interior of the photovoltaic module 5, extending its service life.

[0034] Photovoltaic module 5 is a bifacial double-glass module. The bifacial double-glass design allows photovoltaic module 5 to not only absorb sunlight from the front, but also generate electricity using the light reflected from the back, which greatly improves the utilization rate of solar energy. At the same time, the double-glass structure has better weather resistance, anti-aging performance and fire resistance, and can operate stably in various harsh environments.

[0035] The drive unit 9 is connected to the electrical box 3. The drive unit 9 can precisely drive the active rotating shaft 7 to rotate according to the instructions of the solar tracking system, thereby driving the photovoltaic panel frame 6 to adjust the angle. This ensures that the photovoltaic window can be adjusted to the optimal angle in a timely and accurate manner under different lighting conditions, thereby improving power generation efficiency.

[0036] A temperature detector 2 is installed on the frame 6 of the photovoltaic panel. The temperature detector 2 collects the current module temperature and feeds it back to the backend system. Temperature has a significant impact on the power generation efficiency of the photovoltaic module 5; excessively high temperatures can lead to a decrease in the performance of the photovoltaic module 5. Through the monitoring of the temperature detector 2, the backend control system can take timely measures, such as adjusting the angle of the photovoltaic panel frame 6 to increase ventilation and heat dissipation, or activating the cooling device, to ensure that the photovoltaic module 5 operates at a suitable temperature, thereby improving power generation efficiency and stability.

[0037] Linkage rod 4 connects all the photovoltaic panel frames 6 together, creating a linkage mechanism. When one photovoltaic panel frame 6 rotates under the drive of the active rotating shaft 7, linkage rod 4 transmits this motion to the other photovoltaic panel frames 6, causing them to rotate and open synchronously. This linkage design not only improves the overall coordination and aesthetics of the photovoltaic window but also ensures that all photovoltaic modules 5 can simultaneously adjust to the optimal lighting angle, thereby improving power generation efficiency.

[0038] A second bearing 12 is installed at the connection point between the photovoltaic panel frame 6 and the linkage rod 4. Bearing washers 11 are installed on the upper and lower sides of the second bearing 12, serving as buffers and protectors. During the rotation of the photovoltaic panel frame 6, the bearing washers 11 absorb and disperse the impact force on the bearing, reducing wear between the bearing and other components and extending the service life of the bearing and related parts. Simultaneously, the bearing washers 11 can also adjust the bearing's installation clearance to ensure its normal operation.

[0039] The photovoltaic panel frame 6, the linkage rod 4, and the second bearing 12 are connected by a bolt and nut assembly. This connection method has the advantages of strong connection and easy disassembly, which can ensure the connection stability between the components and facilitate disassembly and replacement during maintenance and repair.

[0040] The active rotating shaft 7 is connected to the window frame 1 via the first bearing 10.

[0041] Both the first bearing 10 and the second bearing 12 are ball bearings. Ball bearings have a low coefficient of rolling friction, which significantly reduces friction during rotation, resulting in smoother rotation of the drive shaft 7 and the linkage rod 4, reducing energy loss and improving the working efficiency of the drive device 9. Secondly, ball bearings have high rotational precision and stability, ensuring the accuracy and reliability of the photovoltaic panel frame 6 during rotation, guaranteeing the normal operation of the photovoltaic window. Furthermore, ball bearings have a strong load-bearing capacity, capable of supporting the weight of the photovoltaic panel frame 6 and the photovoltaic module 5, as well as the impact forces generated during rotation, extending the bearing's service life.

[0042] The window frame 1 is provided with a linkage fitting groove 101. When the photovoltaic panel frame 6 is in the closed state, the linkage rod 4 is fitted in the linkage fitting groove 101. The side wall of the linkage fitting groove 101 plays a limiting role for the linkage rod 4, so that the photovoltaic panel frame 6 opens towards the side of the window frame 1. This design not only ensures the stability of the photovoltaic window in the closed state, but also provides the necessary support and guidance for the opening of the photovoltaic panel frame 6, ensuring the normal opening and closing function of the photovoltaic window.

[0043] The lower edge of the photovoltaic panel frame 6 is connected to the limiting component 14, and the other end of the limiting component 14 is connected to the window frame 1. The limiting component 14 restricts the rotation angle of the photovoltaic panel frame 6. By reasonably setting the length and position of the limiting component 14, it can be ensured that the photovoltaic panel frame 6 will not exceed the preset angle range during rotation, avoiding component damage and safety hazards caused by excessive rotation, and improving the safety and reliability of the photovoltaic window. In addition, after the opening angle of the photovoltaic panel frame 6 is determined, the limiting component 14 also reinforces the position of the photovoltaic panel frame 6, so that the photovoltaic panel frame 6 and the photovoltaic module 5 installed in it are not affected by natural wind.

[0044] This invention, through the combined use of a drive device and a linkage rod, enables several photovoltaic modules 5 to be synchronously and accurately adjusted to the optimal angle under different lighting conditions, effectively improving the absorption efficiency of solar energy and thus enhancing power generation efficiency.

[0045] In addition, a temperature detector 2 is installed on the frame 6 of the photovoltaic panel. The temperature detector 2 can collect the current temperature of the photovoltaic module 5 and feed the data back to the back-end, allowing the staff to understand the temperature status of the photovoltaic module in real time. Since temperature has a significant impact on the power generation efficiency of the photovoltaic module 5, excessively high temperature will cause performance degradation. The temperature detector 2 can assist the back-end control system to take timely measures to ensure that the photovoltaic module 5 operates at a suitable temperature, thereby improving power generation efficiency, avoiding performance fluctuations of the photovoltaic module caused by excessively high temperature, enhancing the stability of the photovoltaic window operation, and improving the overall intelligence level of the photovoltaic window.

[0046] Finally, it should be noted that the above are merely preferred embodiments of the utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. However, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the utility model should be included within the protection scope of the utility model.
