Description

Technical Field

[0001] This application belongs to the field of photovoltaic power generation technology, and more specifically, relates to a photovoltaic louver. Background Technology

[0002] In areas with ample sunshine, the photovoltaic industry has developed well, and photovoltaic power generation products are widely used on rooftops, building facades, and other areas.

[0003] With the maturity of power generation technology, the application scope of photovoltaic power generation products has expanded to shading scenarios such as curtain walls, carports, and sunshade louvers, making these applications no longer solely focused on shading functions. For example, in some applications, photovoltaic equipment is combined with traditional louvers to form photovoltaic louvers with dual functions of sun shading and photovoltaic power generation.

[0004] Although photovoltaic louvers offer both shading and photovoltaic power generation functions, most photovoltaic louvers on the market currently suffer from several drawbacks. For example, the angle of the photovoltaic louvers used in existing photovoltaic louvers is fixed, resulting in relatively low power generation efficiency and an inability to meet varying ventilation needs. Furthermore, since the louvers house photovoltaic power generation components, dust accumulation on these components significantly impacts their power generation efficiency. Additionally, when the louvers are open, the lack of shading allows dust to easily enter the room, resulting in poor dust prevention. Summary of the Invention

[0005] The purpose of this application is to provide a photovoltaic louver to solve the technical problems of poor dust prevention and low power generation efficiency of existing photovoltaic louver products.

[0006] To achieve the above objectives, the technical solution adopted in this application is to provide a photovoltaic louver, which includes:

[0007] A frame, an external louver assembly and a dustproof net arranged sequentially inside the frame and along the thickness direction of the frame, and a cleaning assembly disposed between the external louver assembly and the dustproof net;

[0008] The external louver assembly includes a plurality of rotatably arranged external louvers, and a first driving device for driving each of the external louvers to rotate, and a photovoltaic panel is provided on each of the external louvers.

[0009] The cleaning component includes a cleaning brush and a second driving device, the second driving device being used to drive the cleaning brush to move linearly along the height or width direction of the frame and to abut against the outer louvers and / or the dustproof net.

[0010] Optionally, the first driving device synchronously drives each of the outer louvers to rotate synchronously.

[0011] Optionally, the first drive device includes a first rotary motor, a first sprocket disposed on the rotating shaft of each of the outer louvers, a second sprocket disposed on the output shaft of the first rotary motor, and a first chain that drives and cooperates with each of the first sprockets and each of the second sprockets.

[0012] Optionally, the first driving device includes a plurality of rotating motors, each of which drives each of the outer louvers to rotate.

[0013] Optionally, the photovoltaic panel is disposed on one side surface or on opposite sides of the outer louver.

[0014] Optionally, the second driving device is a chain drive device arranged along the height or width direction of the frame, including a second rotating motor, a second sprocket, and a second chain; the cleaning brush is disposed on the second chain.

[0015] Optionally, the second driving device is a belt drive device arranged along the height or width direction of the frame, the belt drive device including a second rotating motor, a pulley and a belt; the cleaning brush is disposed on the belt.

[0016] Optionally, the second driving device is a screw and nut transmission device arranged along the height or width direction of the frame, including a second rotating motor, a screw connected to the output shaft of the second rotating motor, a nut rotatably arranged on the screw, and a guide structure, wherein the nut is slidably assembled on the guide structure; the cleaning brush is arranged on the nut.

[0017] Optionally, the photovoltaic louver is also equipped with a battery, which is located at the top of the frame and electrically connected to the photovoltaic panel, the first drive device, and the second drive device.

[0018] Optionally, an inner louver assembly is provided on the side of the frame away from the outer louver assembly, where the dustproof net is located.

[0019] The photovoltaic louvers provided in this application have at least the following beneficial effects:

[0020] First, by setting a first driving device, the first driving device drives each outer louver to rotate. On the one hand, the outer louvers can rotate and adjust according to the sun's altitude so that the photovoltaic panels on them can obtain the maximum amount of sunlight, thereby maintaining the maximum power generation efficiency. On the other hand, when it is necessary to change the size of the louver opening, the first driving device can also drive each outer louver to rotate, thereby actively changing the size of the louver opening.

[0021] Secondly, the blinds are equipped with dustproof nets, which makes them more effective at preventing dust and insects.

[0022] Furthermore, a cleaning brush and a second drive device are installed between the dustproof net and the outer louver assembly. The second drive device is used to drive the cleaning brush to move. When the first drive device drives each outer louver to rotate until the side of the outer louver on which the photovoltaic panel is installed faces the dustproof net, the second drive device drives the cleaning brush. The cleaning brush simultaneously or sequentially wipes and cleans the dust on the surface of the dustproof net and the photovoltaic panel, thereby keeping the dustproof net and the photovoltaic panel clean and improving the power generation efficiency of the photovoltaic panel of the louver.

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0045] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature.

[0046] In the description of this application, "multiple" means two or more, unless otherwise expressly and specifically defined.

[0047] Please refer to the following: Figures 1 to 5 The photovoltaic louvers provided in the embodiments of this application will now be described.

[0048] refer to Figures 1 to 3 and Figure 5The photovoltaic louver described in this application includes a frame 100, an outer louver assembly 200, and a cleaning assembly 400.

[0049] Specifically, the outer louver assembly 200 and the dustproof net 300 are both disposed inside the frame 100. The outer louver assembly 200 and the dustproof net 300 are arranged sequentially in the thickness direction of the frame 100, and the outer louver assembly 200 is disposed on the outer side of the frame 100.

[0050] Furthermore, the dustproof net 300 is detachably mounted on the frame 100. For example, slots are provided on the two opposite inner sides of the frame 100, and the dustproof net 300 is inserted into the slots; or, for another example, slots are provided on the two opposite inner sides of the frame 100, and both ends of the dustproof net 300 are secured in the slots.

[0051] Thus, with the dustproof net 300 installed, the louvers have a good dustproof and insect-proof effect when the outer louver assembly 200 is in the open state.

[0052] Specifically, refer to Figure 4 Each outer louver 210 is equipped with a photovoltaic panel 211. The photovoltaic panel 211 can be installed on one side surface of the outer louver 210 or on the opposite two sides of the outer louver 210. In this way, under sunlight conditions, the photovoltaic panel 211 on each outer louver 210 facing outward and being illuminated by sunlight can generate electricity.

[0053] Furthermore, each of the outer louvers 210 on the outer louver assembly 200 is rotatably mounted on the frame 100. Correspondingly, the outer louver assembly 200 also includes a first driving device 220, which is used to drive each outer louver 210 to rotate, for example, to fully open or close the opening of the frame 100, or to drive each outer louver 210 to rotate to a certain angle so that the photovoltaic panels 211 on each outer louver 210 can obtain the maximum power generation efficiency.

[0054] Specifically, each outer louver 210 can be individually rotatably mounted on the frame 100, or they can be rotatably mounted on the frame 100 in conjunction with each other. Correspondingly, the first driving device 220 can drive one outer louver 210 to rotate individually, or it can drive multiple outer louvers 210 to rotate synchronously. It should be understood that the first driving device 220 is capable of driving the outer louvers 210 to rotate at least 180°.

[0055] More specifically, when the first drive device 220 drives each outer louver 210 individually, the first drive device 220 may be a rotary motor; when the first drive device 220 drives multiple outer louvers 210 synchronously, the first drive device 220 may be composed of a rotary motor and a synchronous motion mechanism, wherein the synchronous mechanism includes, but is not limited to, chains, belts, etc.

[0056] By rotating each outer louver 210 and simultaneously providing a corresponding first drive device 220 to drive the rotation of the outer louver 210, the following can be achieved: on the one hand, the outer louver 210 can rotate according to the user's needs under the drive of the first drive device 220 to change the opening size of the frame 100, thereby achieving different ventilation efficiencies; on the other hand, under different solar altitudes, the first drive device 220 can drive each outer louver 210 to change its rotation angle in real time, so that the photovoltaic panels 211 on each outer louver 210 can be perpendicular to the sunlight, thereby obtaining the maximum power generation efficiency.

[0057] A cleaning component 400 is disposed between the outer louver component 200 and the dustproof net 300. It includes a cleaning brush 410 and a second driving device 420. The second driving device 420 drives the cleaning brush 410 to move linearly along the height or width direction of the frame 100. During this process, the cleaning brush 410 contacts the surface of the outer louver 210 and the surface of the dustproof net 300, thereby achieving the cleaning of the outer louver 210 and the dustproof net 300. Specifically, the cleaning brush 410 can be a single-sided brush or a double-sided brush. In the single-sided configuration, the second drive device 420 is a chain drive or belt drive. Driven by the second drive device 420, the cleaning brush 410 travels along a circumferential path, sequentially contacting the dustproof net 300 and the outer louvers 210. In the double-sided configuration, both sides of the cleaning brush 410 simultaneously contact the dustproof net 300 and the outer louvers 210, respectively. The second drive device 420 is a linear drive device, driving the cleaning brush 410 to reciprocate linearly, thereby cleaning the dustproof net 300 and the outer louvers 210.

[0058] Overall, the working process of the photovoltaic louvers in this application is as follows:

[0059] With the outer louvers 210 open, the first drive device 220 drives each outer louver 210 to rotate according to the change in solar altitude so that the photovoltaic panel 211 can obtain the maximum power generation efficiency.

[0060] With the outer louver 210 closed, the second drive device 420 drives the cleaning brush 410 to move and contact the dustproof net 300 and / or the outer louver 210, thereby removing dust from the dustproof net 300 and the outer louver 210, keeping the dustproof net 300 clean to ensure ventilation efficiency, and keeping the photovoltaic panel 211 on the outer louver 210 clean to ensure power generation efficiency.

[0061] It is understood that in some embodiments of this application, each outer louver 210 is linked together, and the first driving device 220 synchronously drives each outer louver 210 to rotate synchronously. For example, each outer louver 210 is linked together by a linkage mechanism, or each outer louver 210 is driven to rotate by the aforementioned belt synchronization mechanism or chain synchronization mechanism.

[0062] refer to Figure 5 Taking the first drive device 220 as an example of a chain synchronization mechanism, the first drive device 220 includes a first rotating motor 221, a first sprocket 223 disposed on the rotating shaft of each outer louver 210, a second sprocket 422 disposed on the output shaft of the first rotating motor 221, and a chain that cooperates with each first sprocket 223 and second sprocket 422.

[0063] Specifically, the first sprocket 223 can be set at only one end of the shaft of each outer louver 210, or it can be set at both ends of the shaft of the outer louver 210; similarly, the first rotating motor 221 can be set at only one and located on one side of the outer louver assembly 200, or two can be set and located on both sides of the outer louver assembly 200 respectively.

[0064] When the first rotating motor 221 rotates, it drives the first chain 222 to rotate, thereby causing the first chain 222 to drive each first sprocket 223 to rotate, thus realizing the rotation of the outer louvers 210. This allows each outer louver 210 to rotate synchronously to fully open or close the opening of the frame 100, or to make each outer louver 210 rotate according to the change of solar altitude, so that the photovoltaic panels 211 on the outer louvers 210 can obtain the maximum power generation efficiency.

[0065] Understandably, reference Figures 1 to 3 In some other embodiments of this application, each outer louver 210 is individually rotatable, and the first drive device 220 includes a plurality of rotating motors, each rotating motor being configured corresponding to each outer louver 210 for rotating each outer louver 210.

[0066] It is understood that, based on any of the above embodiments, the photovoltaic panel 211 is disposed on one side surface or opposite two sides of the outer louver 210.

[0067] Specifically, when the photovoltaic panels 211 are disposed on opposite sides of the outer louver 210, when the first driving device 220 drives the outer louver 210 to rotate to close the opening of the frame 100, the photovoltaic panels 211 on the outer louver 210 facing the inside of the frame 100 can be cleaned by the cleaning brush 410. At the same time, the photovoltaic panels 211 on the outer louver 210 facing the outside of the frame 100 can still receive sunlight to maintain power generation. Similarly, after one side of the photovoltaic panels 211 on the outer louver 210 is cleaned, the first driving device 220 drives the outer louver 210 to rotate to the side of the uncleaned photovoltaic panels 211 facing the inside of the frame 100, thereby achieving alternating cleaning of the photovoltaic panels 211 with minimal impact on the power generation time of the photovoltaic panels 211, thus improving the power generation efficiency of the photovoltaic louver.

[0068] With the outer louver 210 configured in this way, the photovoltaic panel 211 on either side of the outer louver 210 will not affect the power generation of the photovoltaic panel 211 on the other side when cleaning. Therefore, the photovoltaic louver is suitable for environments with good sunlight and a lot of dust.

[0069] In some embodiments of this application, the second drive device 420 may be a chain drive device arranged along the height or width direction of the frame 100, which includes a second rotating motor 421, a second sprocket 422, and a second chain 423, and a cleaning brush 410 is disposed on the second chain 423. For example, see reference. Figure 1 , Figure 1 A schematic diagram showing the chain drive device positioned along the height of the frame 100.

[0070] Specifically, the second drive device 420 can be a single set or two sets. When two sets of the second drive device 420 are provided, the two sets of the second drive device 420 are respectively set on opposite inner sides of the frame 100, and the cleaning brush 410 is mounted between the second chains 423 of the two sets of the second drive device 420. The two sets of the second drive device 420 simultaneously drive the cleaning brush 410 to move.

[0071] Furthermore, the spacing between the two parallel segments on the second chain 423 is adapted to the spacing between the photovoltaic panels 211 and the dustproof net 300 on each of the outer louvers 210 when they are closed. In this way, when the second chain 423 rotates, the cleaning brush 410 can maintain contact with the dustproof net 300 and / or the photovoltaic panel 211 to ensure the cleaning effect.

[0072] Furthermore, the cleaning brush 410 can be provided as a single item or as two items. With a single cleaning brush 410, the second chain 423 drives the cleaning brush 410 to move along the chain's circular path, thus cleaning the dustproof net 300 and the photovoltaic panel 211 sequentially. With two cleaning brushes 410, each brush is positioned on a parallel section of the second chain 423. Thus, when the second rotating motor 421 drives the second chain 423 to rotate, the cleaning brush 410 in contact with the dustproof net 300 moves upward, while the cleaning brush 410 in contact with the photovoltaic panel 211 moves downward simultaneously; or vice versa, the cleaning brush 410 in contact with the dustproof net 300 moves downward, while the cleaning brush 410 in contact with the photovoltaic panel 211 moves upward simultaneously, thereby improving cleaning efficiency.

[0073] Alternatively, in addition to the embodiments described above, in other embodiments of this application, the second drive device 420 may also be a belt drive device arranged along the height or width direction of the frame 100. For example, see reference... Figure 2 , Figure 2 This is a schematic diagram showing the belt drive device positioned along the height of the frame 100.

[0074] The belt drive includes a second rotating motor 421, a pulley 424, and a belt 425; a cleaning brush 410 is disposed on the belt 425. It should be understood that in this embodiment, the arrangement of the second rotating motor 421, pulley 424, and belt 425 is consistent with the arrangement of the second rotating motor 421, second sprocket 422, and second chain 423 in the above embodiments. The arrangement of the cleaning brush 410 and the cleaning process are also consistent with the above embodiments, and therefore will not be described again here.

[0075] Alternatively, in some other embodiments of this application, the second drive device 420 is a lead screw and nut transmission device arranged along the height or width direction of the frame 100. For example, see reference... Figure 3 and Figure 4 , Figure 3 and Figure 4 This is a schematic diagram showing the screw and nut drive device arranged along the height direction of the frame 100.

[0076] Specifically, the second drive device 420 includes a second rotary motor 421, a lead screw 426, a nut 427, and a guide structure (not shown in the figure); the cleaning brush 410 is disposed on the nut 427.

[0077] The output shaft of the second rotary motor 421 is connected to the lead screw 426. The guide structure can be a guide rail or a guide groove on the frame 100, and the guide structure extends along the height of the frame 100. The nut 427 is rotatably mounted on the lead screw 426 and slidably mounted on the guide structure. Thus, when the second rotary motor 421 rotates, the nut 427 moves linearly along the guide structure under the drive of the lead screw 426, thereby driving the cleaning brush 410 to move.

[0078] Furthermore, the second drive device 420 can be provided with only one on one side of the opening in the frame 100, or two can be provided on opposite sides of the opening in the frame 100.

[0079] Specifically, brush bodies are provided on both opposite sides of the cleaning brush 410. When there is only one second drive device 420, one end of the cleaning brush 410 is attached to the nut 427. When there are two second drive devices 420, both ends of the cleaning brush 410 are respectively attached to the nuts 427 of the two lead screw nut drive devices.

[0080] Furthermore, with all the outer louvers 210 closed, both sides of the cleaning brush 410 simultaneously abut against the dustproof net 300 and the outer louvers 210. Thus, when the second rotary motor 421 rotates, the lead screw 426 drives the nut 427 to move linearly along the length of the lead screw 426 (i.e., the height direction of the frame 100), and the nut 427 drives the cleaning brush 410 to reciprocate along the height direction of the frame 100. Furthermore, since the cleaning brush 410 has brush bodies on both opposite sides, when the cleaning brush 410 moves, the brush bodies on its two sides respectively contact the photovoltaic panels 211 on the dustproof net 300 and the outer louvers 210, thereby achieving simultaneous cleaning of the photovoltaic panels 211 on the dustproof net 300 and the outer louvers 210, resulting in high cleaning efficiency.

[0081] Understandably, reference Figures 1 to 3 and Figure 5 In some embodiments of this application, the photovoltaic louvers are also provided with a storage battery 500, which is located on the top of the frame 100 and is electrically connected to the photovoltaic panel 211, the first drive device 220 and the second drive device 420 on each of the outer louvers 210.

[0082] By placing the battery 500 on top of the frame 100, water leakage can be prevented from damaging the battery 500, thereby improving the safety and reliability of the battery 500. Furthermore, in addition to being electrically connected to each photovoltaic panel 211, the battery 500 is also electrically connected to the first drive device 220 and the second drive device 420. In this way, the electrical energy generated by the photovoltaic panels 211 stored in the battery 500 can be used to drive the cleaning brush 410 to move and drive each outer louver 210 to rotate, thereby achieving self-sufficiency in the energy required by the photovoltaic louvers.

[0083] Understandably, reference Figures 1 to 5 In some embodiments of this application, an inner louver assembly 600 is provided on the side of the frame 100 away from the outer louver assembly 200, where the dustproof net 300 is located.

[0084] It should be understood that the inner louver assembly 600 includes several inner louvers fixed at an inclined angle. Specifically, each inner louver is fixed to the two opposite inner sidewalls of the frame 100 by bolts. At the same time, each inner louver is inclined towards the bottom of the frame 100 and close to the inner side of the frame 100. Furthermore, the projections of the top and bottom ends of two adjacent inner louvers in the thickness direction of the frame 100 coincide. That is, a curved ventilation channel is formed between two adjacent inner louvers. Thus, when there is heavy rain outside, the inner louver assembly 600 can effectively block rainwater.

[0085] Furthermore, the inner louver assembly 600 also includes a water collection trough disposed at the bottom of each inner louver, so that rainwater blocked by each inner louver can be collected by the water collection trough after flowing along each inner louver to the bottom of the inner louver assembly 600; furthermore, a drain pipe for draining the rainwater accumulated in the water collection trough can also be disposed at the bottom of the water collection trough.

[0086] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
