Description

Technical Field

[0001] This invention belongs to the field of venetian blind technology, and specifically relates to a photovoltaic venetian blind. Background Technology

[0002] In recent years, solar cells, utilizing solar energy, have attracted attention as a powerful alternative energy source for the future, and with the decreasing cost of solar cells, the related global market size is growing rapidly. Building photovoltaic (PV) blinds are products that integrate building louver shading with photovoltaic power generation, possessing the dual functions of shading and photovoltaic power generation. The photovoltaic louvers in these blinds have two application methods: one uses a louvered form, which can only adjust the louver angle but cannot retract the photovoltaic louvers, and the angle adjustment mechanism is costly; currently, most domestically developed building photovoltaic blinds adopt the louvered form. The other uses a veneer form, which allows for both louver angle adjustment and the unfolding and retraction of the photovoltaic louvers, and has a lower application cost.

[0003] A search revealed that invention patent application number 201910381393.8 discloses a building photovoltaic louver. The shortcomings of this prior art are: because the sun's direct point moves between the Tropic of Cancer and the Tropic of Capricorn throughout the year, the daily solar radiation varies periodically throughout the year. The photovoltaic louvers in this prior art cannot adaptively adjust their angle according to the changes in the sun's direct point, resulting in poor light reception and low energy conversion efficiency. Furthermore, it addresses the problem of frost covering the sun-facing side of the photovoltaic louvers affecting the absorption of sunlight by the photovoltaic panels. Summary of the Invention

The louver assembly is provided with a temperature sensor, a humidity sensor, a signal processor, and a controller. The temperature sensor is used to detect the ambient temperature. The signal processor receives the temperature signal output by the temperature sensor and controls the operation of the circulation loop through the controller.

[0008] Preferably, the humidity sensor is used to detect the humidity of the environment around the louver assembly, and the signal processor is used to receive the signal output by the humidity sensor and control the operation of the loop through the controller.

[0009] Preferably, the venetian blind assembly includes a main frame, a rotating shaft for driving the main frame to rotate is fixedly connected at the central axis of the main frame, a drive motor is provided at the end of the rotating shaft, a mounting groove is provided on the main frame, two layers of transparent plates are fixedly connected in sequence along the longitudinal direction of the mounting groove, and a photovoltaic panel is provided between the two layers of transparent plates.

[0010] Preferably, a battery is provided within the main frame, which is used to receive electrical energy output from the photovoltaic panel and to provide electrical energy to the drive motor that drives the rotating shaft.

[0011] Preferably, the photosensitive component includes a light-shielding housing located on the light-facing surface of the main frame. The light-shielding housing contains several sets of light-shielding tubes, which are perpendicular to the photovoltaic panel. The light-shielding housing contains a light intensity sensor located below the end of the light-shielding tube to receive the sunlight beams passing through the light-shielding tube. The signal processor transmits the output signal from the light intensity sensor to the controller, and the controller controls the drive motor to rotate the main frame via a rotating shaft.

[0012] Preferably, it also includes an inner window frame, which is located inside the curtain wall frame. Multiple sets of light-shielding plates are arranged vertically at intervals along the inner window frame. The light-shielding plates are rotatably connected to the inner window frame.

[0014] Preferably, a sealing ring and a sealing structural adhesive are provided at the joint between the two transparent panels and the photovoltaic panel and the mounting groove.

[0015] Preferably, the main frame is provided with protective ends at both ends.

[0016] Due to the adoption of the above technical solution, the beneficial effects achieved by this invention are as follows:

[0017] 1. In this application, the curtain wall frame is installed on the exterior of the building structure. The curtain wall provides functions such as thermal insulation, noise reduction, waterproofing, and windproofing. Louver components are rotatably mounted on the curtain wall frame. Users comprehensively consider both the internal and external environments of the building and then improve the internal environment, such as temperature, ventilation, and light intensity, by rotating the louver components. Solar panels convert solar energy into electrical energy. A solar energy storage device is installed within the building to receive and store the electrical energy output from the photovoltaic panels. The stored energy can provide clean power to the building's internal electrical equipment, achieving energy conservation and emission reduction.

[0018] The photosensitive module receives the intensity of external light and controls the rotation of the venetian blind assembly through electrical signals. As the photosensitive module rotates with the venetian blind assembly, the angle of the photosensitive module relative to the sunlight also changes continuously. When the photosensitive module senses that the intensity of external light is at its maximum value in one rotation cycle of the venetian blind assembly, it means that the venetian blind position at the maximum light intensity is the optimal position for the photovoltaic panel to receive sunlight. At this time, the photovoltaic panel has the best conversion efficiency in converting solar energy into electrical energy.

[0019] 2. In a preferred embodiment of the present invention, the temperature sensor, signal processor, and controller are configured to control the water pump to start / stop. The control module controls the water pump to start, and the water in the energy storage tank circulates along the conduit, the transparent circulation channel, and the energy storage tank under the action of the water pump. During the process of the water flowing through the transparent circulation channel, the water absorbs the temperature around the photovoltaic panel, thereby cooling the photovoltaic panel. At the same time, the energy storage tank has a heat preservation structure, and the heat energy absorbed by the water is finally stored in the energy storage tank.

[0020] After receiving the output signals from the temperature and humidity sensors, the signal processor controls the water pump to start through the control module in the controller. The water pump causes the hot water stored in the energy storage tank to circulate along the conduit and the transparent circulation channel. As the hot water flows through the transparent circulation channel, it heats the transparent panel, melting the snow and frost on the panel and causing them to fall off, so that the photovoltaic panel can receive sufficient sunlight after sunrise.

[0021] 3. In a preferred embodiment of the present invention, the main frame can be made of aluminum alloy to ensure its structural strength. Simultaneously, aluminum alloy is lightweight, reducing pressure on the curtain wall frame. The controller is connected to the drive motor via wires. The photosensitive component controls the drive motor through a signal processor and controller, enabling the drive motor to rotate the main frame adaptively according to sunlight, thereby increasing the energy conversion efficiency of the photovoltaic panels. The mounting groove provides a stable and reliable installation position for the transparent panel and photovoltaic panels. The outer wall of the mounting groove provides support and protection for the edges of the transparent panel and photovoltaic panels. The transparent panel, positioned on both sides of the photovoltaic panel, effectively protects the photovoltaic panels and increases their service life.

[0022] The main frame is equipped with a battery, which is used to receive electrical energy output from the photovoltaic panel and to provide electrical energy to the drive motor that drives the rotating shaft.

[0023] 4. In a preferred embodiment of the present invention, a sealing ring and a sealing structural adhesive are provided at the joint between the two transparent plates and the photovoltaic panel and the mounting groove. The sealing ring and the sealing structural adhesive are provided to increase the adhesion and sealing between the photovoltaic panel, the transparent plate and the mounting groove, isolate the photovoltaic panel from the external environment, prevent the electrical circles on the photovoltaic panel from oxidation, moisture and other damage, and increase the service life of the photovoltaic panel.

[0024] 5. In a preferred embodiment of the present invention, a black coating may be provided on the inner and outer surfaces of the light-shielding housing to ensure that the light-shielding housing itself is opaque and does not reflect light. A black coating is provided on the inner surface of the light-shielding tube to prevent sunlight entering the tube from being reflected by the tube wall onto the surface of the light intensity sensor. When the sunlight has a large angle with the axis of the light-shielding tube, such that the sunlight cannot pass through the inner channel of the light-shielding tube to illuminate the light intensity sensor, the light intensity sensor outputs the detected light intensity signal to the signal processor. The signal processor, through a controller, controls the drive motor to rotate the main frame via a rotating shaft. Simultaneously, the relative angle between the light-shielding tube and the sunlight also changes. When the light-shielding tube rotates until its axis is parallel to the sunlight, sunlight can pass through the inner channel of the light-shielding tube to illuminate the light intensity sensor, and at this time, the light intensity detected by the light intensity sensor is the maximum value for the day. After the light intensity sensor detects the maximum light intensity, the signal processor and controller control the drive motor to stop rotating, thus stopping the main frame from rotating. At this time, the angle between the sun-facing surface of the main frame and the sunlight is perpendicular, and the photovoltaic panel reaches the maximum light-to-electricity conversion efficiency. It should be noted that the above adjustment process needs to be carried out at noon every day, when the distance between the building location and the sunlight is shortest, the sunlight is strongest, and the power generation of the photovoltaic panel is the greatest. Therefore, by ensuring that the sun-facing surface of the photovoltaic panel is perpendicular to the sunlight during the period of maximum light intensity each day, the light-to-electricity conversion efficiency of the photovoltaic panel can be significantly increased.

[0025] 6. In a preferred embodiment of the present invention, the indoor lighting effect of the building is controlled by the arrangement of the light-shielding plates. When it is necessary to increase the indoor light intake, the drive mechanism drives any one light-shielding plate to rotate. This light-shielding plate drives the other light-shielding plates to rotate synchronously through the hinged connecting rod, so that the gap between adjacent light-shielding plates increases, and external light shines into the interior of the building through the gap. Conversely, the drive mechanism adjusts any light-shielding plate to rotate in the opposite direction, so that the gap between adjacent light-shielding plates decreases, thereby reducing the intake of external light into the interior of the building.

[0026] Specifically, when it is necessary to increase the amount of light entering the building's interior, the electric telescopic pole retracts. The retracting pole, via a connecting seat, moves the control rod downwards. The control rod, through a support, pulls the light-shielding panel clockwise, thus increasing the gap between adjacent light-shielding panels. Conversely, when the electric telescopic pole extends, it moves the control rod upwards via the connecting seat. The control rod, through a support, moves the light-shielding panel counterclockwise, thus decreasing the gap between adjacent light-shielding panels. Attached Figure Description

[0036] Many specific details are set forth in the following description in order to provide a full understanding of the invention.

[0040] Reference Figures 1-5 A photovoltaic louver includes a curtain wall frame 10, with several sets of louver components arranged vertically at intervals inside the curtain wall frame 10. Each set of louver components is rotatably connected to the curtain wall frame 10 so that the angle of the louver components can be adjusted. A photovoltaic panel 40 is provided on the louver components, and a photosensitive component is provided on the louver components. The photosensitive component is used to sense the intensity of external light and convert the light signal into an electrical signal to control and adjust the angle of the louver components so that sunlight shines perpendicularly on the photovoltaic panel 40.

[0041] Those skilled in the art will understand that, because the sun's direct rays move between the Tropic of Cancer and the Tropic of Capricorn throughout the year, the length of day and night and the noon sun's altitude at any location on Earth undergo periodic changes throughout the year, resulting in periodic variations in daily solar radiation. The curtain wall frame 10 in this application is installed on the exterior of the building structure. The curtain wall provides functions such as insulation, noise reduction, waterproofing, and windproofing. The louvered components are rotatably mounted on the curtain wall frame 10. Users can comprehensively consider both the internal and external environments of the building and then improve the internal environment, such as temperature, ventilation, and light intensity, by rotating the louvered components. Specifically, when it is necessary to increase indoor ventilation efficiency or increase the amount of light entering the building, the louvered components are rotated to create a channel between adjacent louvered components. The larger the rotation angle of the louvered components, the wider the channel, the greater the amount of light entering the building, and the faster the ventilation efficiency. Furthermore, the photovoltaic panels 40 can convert solar energy into electrical energy. The building is equipped with solar energy storage devices to receive and store the electrical energy output by the photovoltaic panels 40. The electrical energy stored in the solar energy storage devices can provide clean electrical energy for the electrical equipment inside the building, thereby achieving energy conservation and emission reduction in the building.

[0042] Furthermore, since the sun's direct point of contact changes throughout the year, the photosensitive component receives the intensity of external light and controls the rotation of the louvered components via electrical signals. As the photosensitive component rotates with the louvered components, its angle relative to the sunlight also changes. When the photosensitive component senses that the external light intensity is at its maximum within a louvered component rotation cycle, it indicates that the louvered position at this maximum light intensity is the optimal position for the photovoltaic panel 40 to receive sunlight. At this point, the photovoltaic panel 40 achieves optimal conversion efficiency in converting solar energy into electrical energy. It should be noted that on cloudy or rainy days, or during the period from sunset to sunrise, when the ambient light is weak and the light intensity is low, the photosensitive component can control the louvered components to rotate to a vertical position. In this case, adjacent louvered components are connected end-to-end, providing insulation and noise reduction for the building structure.

[0043] It should also be noted that since the daily variation in the angle of direct sunlight is relatively small, adjusting the angle of the blind assembly every day is not very meaningful. Therefore, the above adjustment frequency can be set to once a week or once a month.

[0044] As a preferred embodiment of this application, refer to Figure 1 , 24, 5. The photovoltaic panel 40 has transparent plates 30 on both the upper and lower ends. The transparent plate 30 at the upper end of the photovoltaic panel 40 has a transparent circulation channel 31. The louver assembly has an embedded energy storage water tank 70. The energy storage water tank 70 and the two ends of the transparent circulation channel 31 are connected by a conduit 71 to form a continuous circulation loop. The louver assembly is equipped with a temperature sensor 90, a humidity sensor 91, a signal processor 53 and a controller 54. The temperature sensor 90 is used to detect the ambient temperature. The signal processor 53 receives the temperature signal output by the temperature sensor 90 and controls the operation of the circulation loop through the controller 54.

[0045] Temperature sensor 90 is used to detect the ambient temperature. When temperature sensor 90 detects a high ambient temperature, it transmits the temperature signal to signal processor 53. Signal processor 53 converts the temperature signal into an electrical signal and transmits it to the corresponding control module in controller 54. A water pump (not shown in the figure) is installed on conduit 71. Controller 54 controls the water pump to start / stop through the control module. Water in energy storage tank 70 circulates along conduit 71, transparent circulation channel 31, and energy storage tank 70 under the action of the water pump. During the flow of water through transparent circulation channel 31, the water absorbs the temperature around photovoltaic panel 40, thereby cooling photovoltaic panel 40. At the same time, energy storage tank 70 has a heat preservation structure, and the heat energy absorbed by the water is ultimately stored in energy storage tank 70.

[0046] Furthermore, the humidity sensor 91 is used to detect the humidity of the environment around the louver assembly, and the signal processor 53 is used to receive the signal output by the humidity sensor 91 and control the operation of the loop through the controller 54.

[0047] When the main building is located in a cold winter area, the humidity sensor 91 detects the ambient humidity around the louver assembly before sunrise. When the ambient humidity around the louver assembly meets the frost formation conditions or the louver assembly is covered with snow, and the temperature sensor 90 detects that the ambient temperature around the louver assembly is below 0 degrees Celsius, frost will form on the surface of the louver assembly. At this time, after receiving the output signals from the temperature sensor 90 and the humidity sensor 91, the signal processor 53 controls the water pump to start through the control module in the controller 54. The water pump causes the hot water stored in the energy storage tank 70 to circulate along the conduit 71 and the transparent circulation channel 31. As the hot water flows through the transparent circulation channel 31, it heats the transparent panel 30, melting the snow and frost on the transparent panel 30, which then falls off the transparent panel 30, so that the photovoltaic panel 40 can receive sufficient sunlight after sunrise. When the temperature is high, the water pump turns on to circulate the water in the energy storage tank 70, so that the energy storage tank 70 stores heat to heat the transparent plate 30 when it frosts over the next time.

[0048] The double-layer transparent panel 30 can effectively protect the photovoltaic panel 40 and increase its service life. The transparent panel 30 can be made of a material with good light transmittance, such as tempered glass or PVC.

[0049] As a specific implementation of a venetian blind assembly, refer to Figure 1 , Figure 2 , Figure 5 The louver assembly includes a main frame 20, a rotating shaft 21 for driving the main frame 20 to rotate is fixedly connected at the central axis of the main frame 20, a drive motor is provided at the end of the rotating shaft 21, an installation groove 22 is provided on the main frame 20, two layers of transparent plates 30 are fixedly connected in sequence along the longitudinal direction of the installation groove 22, and a photovoltaic panel 40 is provided between the two layers of transparent plates 30.

[0050] The main frame 20 can be made of aluminum alloy to ensure its structural strength. At the same time, the lightweight nature of aluminum alloy reduces pressure on the curtain wall frame 10. The controller 54 is connected to the drive motor via wires. The photosensitive component controls the drive motor through the signal processor 53 and controller 54, causing the drive motor to rotate the main frame 20 adaptively according to sunlight via the rotating shaft 21, thereby increasing the energy conversion efficiency of the photovoltaic panel 40. The mounting groove 22 provides a stable and reliable installation position for the transparent panel 30 and the photovoltaic panel 40. The outer wall of the mounting groove 22 provides support and protection for the edges of the transparent panel 30 and the photovoltaic panel 40. The transparent panel 30, located on both sides of the photovoltaic panel 40, effectively protects the photovoltaic panel 40 and increases its service life.

[0051] Furthermore, a sealing ring 80 and a sealing structural adhesive 81 are provided at the joint between the two transparent panels 30 and the photovoltaic panel 40 and the mounting groove 22. The sealing ring 80 and the sealing structural adhesive 81 are provided to increase the adhesion and sealing between the photovoltaic panel 40, the transparent panel 30 and the mounting groove 22, isolate the photovoltaic panel 40 from the external environment, prevent the electrical circles on the photovoltaic panel 40 from oxidation, moisture and other damage, and increase the service life of the photovoltaic panel 40.

[0052] The main frame 20 is provided with protective end caps 23 at both ends. The protective end caps 23 are provided to facilitate the protection of the main frame 20.

[0053] As a preferred embodiment of the main frame 20, refer to Figure 1 , 2 5. A battery 60 is provided inside the main frame 20. The battery 60 is used to receive the electrical energy output by the photovoltaic panel 40 and to provide electrical energy for the drive motor that drives the rotating shaft 21 to rotate.

[0054] As a specific implementation of the photosensitive component, refer to Figure 4 The photosensitive component includes a light-shielding housing 50, which is located on the light-facing surface of the main frame 20. The light-shielding housing 50 is provided with several sets of light-shielding tubes 51, which are arranged perpendicularly to the photovoltaic panel 40. The light-shielding housing 50 is provided with a light intensity sensor 52, which is located below the end of the light-shielding tube 51 to receive the sunlight beams passing through the light-shielding tube 51. The signal processor 53 transmits the output signal of the light intensity sensor 52 to the controller 54. The controller 54 controls the drive motor to drive the main frame 20 to rotate through the rotating shaft 21.

[0055] Specifically, a black coating can be applied to the inner and outer surfaces of the light-shielding housing 50 to ensure that the light-shielding housing 50 itself is opaque and does not reflect light. A black coating is also applied to the inner surface of the light-shielding tube 51 to prevent sunlight entering the tube from being reflected by the tube wall onto the surface of the light intensity sensor 52. When the sunlight has a large angle with the axis of the light-shielding tube 51, preventing it from passing through the inner channel of the tube and hitting the light intensity sensor 52, the light intensity sensor 52 outputs the detected light intensity signal to the signal processor 53. The signal processor 53, through the controller 54, controls the drive motor to rotate the main frame 20 via the rotating shaft 21. Simultaneously, the relative angle between the light-shielding tube 51 and the sunlight changes accordingly. When the light-shielding tube 51 rotates until its axis is parallel to the sunlight, sunlight can pass through the inner channel of the tube and hit the light intensity sensor 52. At this time, the light intensity detected by the light intensity sensor 52 is... When the maximum daily light intensity is detected by the light intensity sensor 52, the signal processor 53 and controller 54 control the drive motor to stop rotating, thus stopping the main frame 20 from rotating. At this time, the angle between the sun-facing surface of the main frame 20 and the sunlight is perpendicular, and the photovoltaic panel 40 reaches the maximum light-to-electricity conversion efficiency. It should be noted that the above adjustment process needs to be carried out at noon every day, when the distance between the building location and the sunlight is shortest, the sunlight is strongest, and the power generation of the photovoltaic panel 40 is the greatest. Therefore, by ensuring that the sun-facing surface of the photovoltaic panel 40 is perpendicular to the sunlight during the period of maximum daily light intensity, the light-to-electricity conversion efficiency of the photovoltaic panel 40 can be significantly increased.

[0056] As one specific embodiment of this application, refer to Figure 1 and Figure 3 It also includes an inner window frame 11, which is located inside the curtain wall frame 10. Multiple sets of light-shielding plates 100 are arranged vertically at intervals along the inner window frame 11. The light-shielding plates 100 are rotatably connected to the inner window frame 11. Adjacent light-shielding plates 100 are connected at their top and bottom ends by hinged connecting rods 101. The inner window frame 11 is provided with a drive mechanism for driving the light-shielding plates 100 to rotate.

[0057] The lighting effect inside the building is controlled by the setting of the light-shielding plates 100. When it is necessary to increase the amount of light entering the building, the drive mechanism drives any one of the light-shielding plates 100 to rotate. This light-shielding plate 100 drives the other light-shielding plates 100 to rotate synchronously through the hinged connecting rod 101, so that the gap between adjacent light-shielding plates 100 is enlarged, and external light shines into the interior of the building through the gap. Conversely, the drive mechanism adjusts any one of the light-shielding plates 100 to rotate in the opposite direction, so that the gap between adjacent light-shielding plates 100 is reduced, thereby reducing the amount of external light entering the interior of the building.

[0058] Specifically, the drive mechanism includes a control rod 103, each set of light shields 100 is provided with a support 102, each set of supports 102 is hinged to the control rod 103, the control rod 103 is provided with a connecting seat 113, the inner window frame 11 is provided with a support seat 111 on the side, and an electric telescopic rod 112 is rotatably connected to the support seat 111. The telescopic end of the electric telescopic rod 112 is rotatably connected to the connecting seat 113.

[0059] When it is necessary to increase the amount of light entering the building's interior, the electric telescopic rod 112 retracts. The electric telescopic rod 112, via the connecting seat 113, drives the control rod 103 downwards. The control rod 103, via the support 102, pulls the light-shielding plate 100 clockwise, thereby increasing the gap between adjacent light-shielding plates 100. Conversely, when the electric telescopic rod 112 extends, it drives the control rod 103 upwards via the connecting seat 113. The control rod 103, via the support 102, drives the light-shielding plate 100 counterclockwise, thereby decreasing the gap between adjacent light-shielding plates 100.

The photovoltaic panel (40) is provided with transparent plates (30) on both the upper and lower ends. A transparent circulation channel (31) is provided in the transparent plate (30) located at the upper end of the photovoltaic panel (40). An embedded energy storage water tank (70) is provided in the louver assembly. The energy storage water tank (70) and the two ends of the transparent circulation channel (31) are connected to form a continuous circulation loop through the conduit (71). The louver assembly is provided with a temperature sensor (90), a humidity sensor (91), a signal processor (53), and a controller (54). The temperature sensor (90) is used to detect the ambient temperature, and the humidity sensor (91) is used to detect the humidity of the environment around the louver assembly. When the temperature sensor (90) detects that the outside temperature is high, the temperature sensor (90) transmits the temperature signal to the signal processor (53). The signal processor (53) converts the temperature signal into an electrical signal and transmits it to the corresponding control module in the controller (54). A water pump is installed on the conduit (71). The controller (54) controls the water pump to start through the control module for controlling the start / stop of the water pump. The water in the energy storage tank (70) circulates along the conduit (71), the transparent circulation channel (31), and the energy storage tank (70) under the action of the water pump. The water absorbs the temperature around the photovoltaic panel (40) during the process of flowing through the transparent circulation channel (31), thereby cooling the photovoltaic panel (40). At the same time, the energy storage tank (70) has a heat preservation structure, and the heat energy absorbed by the water is finally stored in the energy storage tank (70). When the ambient humidity around the louver assembly meets the frosting conditions or the louver assembly is covered with snow, and the temperature sensor (90) detects that the ambient temperature around the louver assembly is below 0 degrees Celsius, the signal processor (53) receives the output signals from the temperature sensor (90) and the humidity sensor (91), and controls the water pump to start through the control module in the controller (54). The water pump starts, causing the hot water stored in the energy storage tank (70) to circulate along the conduit (71), the transparent circulation channel (31), and the energy storage tank (70). As the hot water flows through the transparent circulation channel (31), it heats the transparent plate (30), causing the frost or snow on the transparent plate (30) to melt and fall off the transparent plate (30), so that the photovoltaic panel (40) can receive sufficient sunlight after sunrise.
