Description

Technical Field

[0001] This utility model relates to the field of photovoltaic power generation technology, and in particular to photovoltaic tracking louvers. Background Technology

[0002] Photovoltaic power generation is a technology that directly converts light energy into electrical energy using the photovoltaic effect at the semiconductor interface. It utilizes the photovoltaic effect of solar cell semiconductor materials to directly convert solar radiation energy into electrical energy. A photovoltaic power generation system mainly consists of three parts: solar panels (modules), controllers, and inverters. The photovoltaic cells convert sunlight into direct current (DC), which is then converted into alternating current (AC) by the inverter, and supplied to households, businesses, or the power grid.

[0003] Photovoltaic louvers are a type of louver product that integrates photovoltaic power generation technology. They combine photovoltaic panels with louvers, providing both the sunshade and ventilation functions of traditional louvers and the ability to convert solar energy into electricity, providing clean power for homes or offices.

[0004] Currently, the power generation efficiency of photovoltaic louvers is indeed affected by a variety of external factors, among which the cleanliness of photovoltaic modules and the surface temperature of photovoltaic panels are two key factors. First, when photovoltaic louvers are exposed to the outdoors for a long time, rainwater or moisture in the air attracts dust, which adheres to the louvers. These dirt and other obstructions reflect, scatter, and absorb solar radiation, resulting in a reduction in the solar radiation received by the photovoltaic modules and a corresponding decrease in output power. Second, the surface temperature of the photovoltaic panels also affects power generation efficiency. Ideally, the photovoltaic panels generate the best power when the surface temperature is 25°C. When the temperature exceeds 25°C, the power generation efficiency of the photovoltaic panels gradually decreases with the increase in temperature. Especially in summer, high temperatures can cause an increase in the internal resistance of photovoltaic modules, thereby affecting the transmission of current and the stability of voltage. Therefore, in order to solve the above problems, a photovoltaic tracking louver is proposed. Utility Model Content

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Example

[0033] like Figures 1-9 As shown, the photovoltaic tracking louver proposed in this utility model includes a frame 1, a light intensity sensor 2 symmetrically fixedly connected to the outer side of the frame 1, a plurality of louver plates 7 rotatably arranged on the inner side of the frame 1, a photovoltaic module 3 installed on the louver plate 7, a plurality of heat dissipation vents 71 through the bottom of the louver plate 7, and a heat-conducting sheet 72 fixedly connected to the inner side of the louver plate 7.

[0034] A cleaning component 6 is provided on the frame 1. The cleaning component 6 includes: a cleaning rack 66 that is slidably disposed inside the frame 1 and a cleaning drive component 61 installed on the frame 1. The cleaning component 6 can be used to clean the surface of multiple photovoltaic modules 3.

[0035] The frame 1 is also provided with an adjustment component 5, which includes: an adjustment drive 50 installed on the frame 1 and multiple adjustment rods 54 rotatably arranged inside the frame 1. The adjustment component 5 can be used to adjust the angle of the multiple photovoltaic modules 3.

[0036] The sweeping drive 61 and the steering drive 50 here are both stepper motors with reduction gears.

[0037] In this design, the frame 1 serves as the main structure. Multiple mounting holes 4 on the frame 1 are used to fix the entire photovoltaic louver in a suitable position. The light intensity sensor 2, which is symmetrically fixed on the outside, senses the external light intensity and direction in real time and transmits this signal to the adjustment drive 50 to adjust the direction of the louver 7. Photovoltaic modules 3 are installed on multiple louver 7 that are rotatably set inside the frame 1 to convert light energy into electrical energy. The heat dissipation vent 71 that is opened through the bottom of the louver 7 cooperates with the heat conduction plate 72 fixed on the inside to effectively dissipate the heat generated by the photovoltaic module 3 and reduce the impact of high temperature on power generation efficiency.

[0038] Furthermore, the cleaning component 6, through the cleaning rack 66 slidably set inside the frame 1, under the drive of the cleaning drive component 61, periodically cleans the surface of multiple photovoltaic modules 3, removes dust and other obstructions, and ensures that the photovoltaic modules 3 can fully receive sunlight.

[0039] Furthermore, the directional component 5 uses the directional drive component 50 installed on the frame 1 to drive multiple directional rods 54 that are rotated inside the frame 1 to adjust the angle of multiple photovoltaic modules 3 so that they are always facing the direction of sunlight, thereby maximizing the power generation efficiency of the photovoltaic modules 3.

[0040] The cleaning assembly 6 also includes: a cleaning drive main gear ring 68 fixedly connected to the output end of the cleaning drive component 61; a second rotating groove 11 is provided through both the upper and lower ends of the frame 1; a lead screw 60 is rotatably connected to the inner side of each second rotating groove 11; a cleaning drive driven gear ring 65 is fixedly connected to the end of the lead screw 60 near the cleaning drive component 61; and a cleaning drive chain 64 is sleeved and connected between the cleaning drive driven gear ring 65 and the cleaning drive main gear ring 68.

[0041] Two lead screws 60 extend to the outside of the frame 1 and are fixedly connected to one end near the cleaning drive component 61 with a cleaning auxiliary tooth ring 63. A cleaning auxiliary chain 62 is sleeved and connected between the two cleaning auxiliary tooth rings 63.

[0042] The lead screw 60 is threadedly connected to the cleaning frame 66. A square storage slot 13 is provided on the inner side wall of the frame 1 near the cleaning drive component 61. Square slots 12 are provided at both the top and bottom ends of the frame 1.

[0043] Two square slots 12 slide relative to each other with the cleaning rack 66. A cleaning brush 67 is fixedly connected to the outside of the cleaning rack 66. Both the cleaning rack 66 and the cleaning brush 67 are located inside the square storage slot 13.

[0044] Furthermore, when the cleaning component is working, the direction of the multiple photovoltaic modules 3 needs to be adjusted by the set adjustment drive 50 so that the multiple photovoltaic modules 3 are kept in a vertical direction and the photovoltaic modules 3 are in contact with each other. Then the cleaning drive 61 is started, and the cleaning drive main gear ring 68 fixedly connected to its output end begins to rotate. Since the cleaning drive slave gear ring 65 and the cleaning drive main gear ring 68 are connected by the cleaning drive chain 64, the cleaning drive slave gear ring 65 will also rotate. The cleaning drive slave gear ring 65 is fixed to one end of the top lead screw 60, thereby driving the lead screw 60 to rotate.

[0045] Furthermore, the lead screws 60 at both the upper and lower ends of the frame 1 extend to the outside, and a cleaning auxiliary toothed ring 63 is fixedly connected to the end near the cleaning drive component 61. The two cleaning auxiliary toothed rings 63 are connected by a cleaning auxiliary chain 62, so that the two lead screws 60 can rotate synchronously.

[0046] Furthermore, the lead screw 60 is threadedly connected to the cleaning frame 66. When the lead screw 60 rotates, the cleaning frame 66 slides along the square groove 12 inside the frame 1 under the drive of the lead screw 60. The cleaning brush 67, which is fixedly connected to the outside of the cleaning frame 66, moves accordingly to clean the surface of the photovoltaic module 3. The square storage groove 13 inside the frame 1 is used to store the cleaning frame 66 and the cleaning brush 67, ensuring that they are not exposed when not in operation.

[0047] The steering assembly 5 also includes: multiple first rotating slots 10 are provided through both sides of the frame 1, the first rotating slots 10 are rotatably connected to the steering rods 54, the outer sides of the multiple steering rods 54 are symmetrically fixedly connected with steering auxiliary gear rings 55, and the multiple steering auxiliary gear rings 55 are connected together with a steering auxiliary chain 56.

[0048] The output end of the directional drive unit 50 is fixedly connected to the directional drive gear ring 51. The end of the bottom directional rotating rod 54 extending to the outside of the frame 1 and close to the directional drive unit 50 is fixedly connected to the directional driven gear ring 53. The directional drive gear ring 51 and the directional driven gear ring 53 are connected together by a directional chain 52.

[0049] Furthermore, the light intensity sensor 2, which is symmetrically fixed on the outside, senses the intensity and direction of the external light in real time and transmits this signal to the directional drive 50 to adjust the direction of the louver 7. After the directional drive 50 is started, the directional drive gear ring 51, which is fixedly connected to its output end, begins to rotate. Since the directional driven gear ring 53 and the directional drive gear ring 51 are connected by the directional chain 52, and the directional driven gear ring 53 is fixed to one end of the directional rotating rod 54 at the bottom, the directional rotating rod 54 at the bottom will rotate accordingly.

[0050] Furthermore, multiple first rotating slots 10 through both sides of the frame 1 are rotatably connected to the directional rotating rods 54, allowing the directional rotating rods 54 to rotate freely within the frame 1. The outer sides of the multiple directional rotating rods 54 are symmetrically fixedly connected with directional auxiliary gear rings 55, and the multiple directional auxiliary gear rings 55 are connected together by directional auxiliary chains 56, thereby ensuring that all directional rotating rods 54 can rotate synchronously.

[0051] The louvered plate 7 is hollow, and multiple heat dissipation vents 71 are located on the bottom side plane of the louvered plate 7. The heat conduction plate 72 is designed on the inner hollow side wall of the louvered plate 7, and multiple mounting holes 4 are provided on the frame 1.

[0052] Furthermore, when the directional lever 54 rotates, it will cause the louvered plate 7 connected to it to change its angle, thereby realizing the orientation adjustment of the photovoltaic module 3.

[0053] In this embodiment, the frame 1 serves as the core support and is fixedly installed through multiple mounting holes 4. Light intensity sensors 2, symmetrically connected to the outside of the frame 1, sense the light intensity and direction in real time, providing data support for the orientation assembly 5. The orientation assembly 5 adjusts the angle of the louvers 7 by rotating the orientation drive 50, ensuring that the photovoltaic module 3 is always directly facing the light.

[0054] Meanwhile, the cleaning component 6 installed inside the frame 1 drives the cleaning frame 66 to slide along the square groove 12 via the cleaning drive component 61, and uses the cleaning brush 67 to clean the surface of the photovoltaic module 3 to maintain its cleanliness. The hollow design of the louvered plate 7 and the setting of the heat dissipation vent 71 and heat conduction plate 72 effectively improve the heat dissipation efficiency and ensure power generation performance;

[0055] Finally, the electricity generated by the multiple photovoltaic modules 3 is collected by DC power, converted by an inverter, and finally fed into the power grid for use.

[0056] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
