Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic panels, in particular to a self-cleaning photovoltaic device applied outdoors. Background Art

[0002] With the growth of the global demand for renewable energy, photovoltaic technology has been widely applied. However, in the outdoor environment, the surface of photovoltaic panels is prone to accumulate pollutants such as dust, bird droppings, and leaves. These pollutants will block sunlight, reduce the light transmittance of photovoltaic panels, and thus affect the power generation efficiency of photovoltaic systems.

[0003] Traditional cleaning methods for photovoltaic panels usually rely on roller brushes for cleaning. However, the roller brushes can only rotate, resulting in a limited contact area of the roller brushes, and may not be able to effectively remove stubborn stains or dust particles tightly attached, so the cleaning efficiency needs to be improved. Summary of the Utility Model

[0004] To solve the above technical problems, the utility model provides a self-cleaning photovoltaic device applied outdoors, which has a simple structure. The roller brush can rotate and move reciprocally at the same time, increasing the number of contacts between the roller brush and the surface of the photovoltaic panel, enabling the roller brush to cover more areas in a single stroke, and thus improving the cleaning efficiency.

[0005] The self-cleaning photovoltaic device applied outdoors of the utility model includes a photovoltaic panel, and a cleaning mechanism is arranged below the photovoltaic panel; the cleaning mechanism includes a moving frame capable of moving perpendicular to the photovoltaic panel. There are two moving frames, which are respectively located on both sides of the photovoltaic panel. The moving frame is provided with a moving block capable of moving along the width direction of the photovoltaic panel. The moving block is fixedly connected with a sleeve. A guiding groove is opened on the inner wall of the sleeve. The distances from the edges of the guiding groove to the center of the guiding groove are inconsistent. A rotating shaft is rotatably connected in the sleeve. A reciprocating shaft is slidably connected in the rotating shaft. The reciprocating shaft is fixedly connected with a guiding shaft extending into the guiding groove. The two reciprocating shafts are fixedly connected with a roller brush, and the roller brush is arranged along the length direction of the photovoltaic panel;

[0006] It further includes a driving mechanism for driving the rotating shaft to rotate.

[0007] As a preferred solution of the utility model, the driving mechanism includes a motor fixed on one of the moving blocks, and the output shaft of the motor is in transmission connection with the rotating shaft.

[0008] As a preferred solution of the utility model, the moving frame is provided with a chain through a sprocket, and the moving block is fixed on the chain.

[0009] As a preferred solution of the utility model, the moving frame is fixed with a smooth shaft, and the moving block is slidably connected with the smooth shaft.

[0010] As a preferred embodiment of the present utility model, it further includes a fixing frame, the fixing frame is provided with a power mechanism, and the output end of the power mechanism is connected to the moving frame.

[0011] As a preferred embodiment of the present utility model, one end of the fixing frame is provided with a telescopic mechanism, and the other end of the telescopic mechanism is connected to the moving frame.

[0013] As a preferred embodiment of the present utility model, the reciprocating shaft is a spline shaft.

[0014] As a preferred embodiment of the present utility model, the fixing frame is provided with a reinforcing frame.

[0015] As a preferred embodiment of the present utility model, the rotating shaft is rotatably connected to the sleeve through a bearing.

[0016] Compared with the prior art, the beneficial effects of the present utility model are as follows: When the device is not in operation, all components are located below the photovoltaic panel and will not affect the efficiency of the photovoltaic panel. When cleaning the photovoltaic panel, by combining water spraying with the rotation and reciprocating movement of the rolling brush, the dust and dirt on the surface of the photovoltaic panel can be efficiently removed, thereby avoiding the reduction of power generation efficiency caused by shading. At the same time, the rolling brush is guided by the chain to slide along the photovoltaic panel, ensuring the uniformity and comprehensiveness of cleaning, and improving the cleaning efficiency of the photovoltaic panel and the overall efficiency of the photovoltaic power generation system.

[0026] Embodiment

[0027] Referring to Figures 1-5 , this embodiment provides a self-cleaning photovoltaic device for outdoor use, including a photovoltaic panel 1, and a cleaning mechanism is arranged below the photovoltaic panel 1; the cleaning mechanism includes a moving frame 2 that can move perpendicular to the photovoltaic panel 1. There are two moving frames 2, which are respectively located on both sides of the photovoltaic panel 1. More specifically, it further includes a fixing frame 14. The fixing frame 14 is provided with a reinforcing frame 19. The fixing frame 14 is provided with a power mechanism 15. The output end of the power mechanism 15 is connected to the moving frame 2. One end of a telescopic mechanism 16 is arranged on the fixing frame 14, and the other end of the telescopic mechanism 16 is connected to the moving frame 2. The telescopic mechanism 16 adopts a telescopic rod, aiming to improve the stability of the moving frame 2. The power mechanism 15 adopts an oil cylinder, an electric telescopic rod or a lead screw structure. As Figure 2 shown, both the power mechanism 15 and the telescopic mechanism 16 are inclined, so that the moving frame 2 can move perpendicular to the photovoltaic panel 1;

[0028] The moving frame 2 is provided with a moving block 3 that can move along the width direction of the photovoltaic panel 1. More specifically, the moving frame 2 is provided with a chain 12 through a sprocket 11. The moving block 3 is fixed on the chain 12. The moving frame 2 is fixed with an optical axis 13. The moving block 3 is slidably connected to the optical axis 13. As Figure 1 andFigure 2 As shown, when the motor 10 at the end of the sprocket 11 drives the sprocket 11 to rotate, the moving block 3 slides along the optical axis 13 driven by the chain 12, thereby driving the rotary brush 9 to move;

[0029] The moving block 3 is fixedly connected with a sleeve 4. The inner wall of the sleeve 4 is provided with guide grooves 5, and the two guide grooves 5 are arranged in parallel. The distances from the edges of the guide grooves 5 to the center of the guide grooves 5 are inconsistent, as Figure 4 and Figure 5 shown. The guide grooves 5 are oval; a rotating shaft 6 is rotatably connected in the sleeve 4 through a bearing, and a reciprocating shaft 7 is slidably connected in the rotating shaft 6. More specifically, the reciprocating shaft 7 is a spline shaft; the reciprocating shaft 7 is fixedly connected with a guide shaft 8 extending into the guide grooves 5, and the two reciprocating shafts 7 are fixedly connected with a rotary brush 9, and the rotary brush 9 is arranged along the length direction of the photovoltaic panel 1;

[0030] It further includes a driving mechanism for driving the rotating shaft 6 to rotate. As Figure 3 shown, more specifically, the driving mechanism includes a motor 10 fixed on one of the moving blocks 3. The output shaft of the motor 10 is in transmission connection with the rotating shaft 6, and the output shaft of the motor 10 and the rotating shaft 6 can be connected by means of a chain 12, a synchronous belt, a belt or a gear;

[0031] At the same time, the top end of the moving frame 2 is fixedly provided with a mounting frame 17, and a spray head 18 is arranged on the mounting frame 17 for spraying water on the photovoltaic panel 1.

[0032] The working principle of this device is as follows: As Figure 2 shown, at this time, the rotary brush 9 and other components are not above the photovoltaic panel 1, and the photovoltaic panel 1 is not blocked by anything, which will not affect the power generation efficiency of the photovoltaic panel 1. When it is necessary to clean the photovoltaic panel 1, operate the power mechanism 15 to move the moving frame 2, the moving block 3, the spray head 18 and the rotary brush 9 upwards. The rotary brush 9 and the spray head 18 move above the photovoltaic panel 1, then turn on the spray head 18 to spray water on the photovoltaic panel 1, and at the same time turn on the driving mechanism to make the rotating shaft 6 rotate, and at the same time make the chain 12 operate;

[0033] When the driving mechanism rotates the rotating shaft 6, since the reciprocating shaft 7 is slidably connected to the rotating shaft 6, the reciprocating shaft 7 is fixedly connected with a guide shaft 8 extending into the guide groove 5, and the distances between the edges of the guide groove 5 and the center of the guide groove 5 are inconsistent. Therefore, while the reciprocating shaft 7 rotates on its own, it is also controlled by the guide shaft 8. When the position of the guide shaft 8 in the guide groove 5 is different, the relative positions of the reciprocating shaft 7 and the rotating shaft 6 are also different. In summary, when the rotating shaft 6 operates, the rotary brush 9 rotates on its own and also reciprocates along its axis direction. And with the cooperation of the chain 12, the rotary brush 9 also slides along the photovoltaic panel 1. The movement of the rotary brush 9 simulates the scrubbing movement, which helps to remove dust, dirt and other impurities attached to the photovoltaic panel 1 and improve the cleaning efficiency.

[0034] It should be understood that in the development process of any actual implementation, such as in any engineering or design project, a large number of specific implementation decisions can be made. Such development efforts may be complex and time-consuming, but for those of ordinary skill in the art who benefit from this disclosure, without excessive experimentation, the development efforts will be a routine task of design, manufacturing and production.

[0035] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered by the scope of the claims of the present invention.
