[0035] In addition, the terms “first”, “second”, etc., if used, are merely used to distinguish between the descriptions and should not be understood as indicating or implying relative importance.

[0036] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0037] Please combine Figures 1 to 5 , the photovoltaic panel self-cleaning device provided by the present invention is now described.

[0038] The photovoltaic panel self-cleaning device comprises a frame 1, a photovoltaic panel 2, a first driving assembly 3, a first cleaning assembly 4, a first protective plate 5, a second driving assembly 6, a second cleaning assembly 7 and a second protective plate 8.

[0039] The first driving component 3 drives the first protective plate 5 to open to expose the photovoltaic panel 2 and drives the first cleaning component 4 to clean the photovoltaic panel 2 . The second driving component 6 drives the second protective plate 8 to open to expose the photovoltaic panel 2 and drives the second cleaning component 7 to clean the photovoltaic panel 2 .

[0040] It can be understood that the photovoltaic panel 2 is installed on the frame 1, the first drive component 3 is transmission connected to the first protective plate 5, the first drive component 3 is also transmission connected to the first cleaning component 4, the second drive component 6 is transmission connected to the second protective plate 8, and the second drive component 6 is also transmission connected to the second cleaning component 7. The first drive component 3 drives the first protective plate 5 to open to expose the photovoltaic panel 2, and drives the first cleaning component 4 to clean the photovoltaic panel 2. The second drive component 6 drives the second protective plate 8 to open to expose the photovoltaic panel 2, and drives the second cleaning component 7 to clean the photovoltaic panel 2, so that the photovoltaic panel self-cleaning device can clean the dirt on the surface by itself, with a high degree of automation, thereby improving the cleaning efficiency.

[0041] It should be supplemented that the first drive component 3 can also drive the first protective plate 5 to move, and the second drive component 6 can also drive the second protective plate 8 to move, so that the first protective plate 5 and the second protective plate 8 can be closed to cover the photovoltaic panel 2, so that the photovoltaic panel 2 can be protected from the influence of the external environment at night.

[0042] It should be noted that the photovoltaic panel self-cleaning device also includes a first thermal insulation material and a second thermal insulation material. The first protective plate 5 is provided with a first mounting groove, and the second protective plate 8 is provided with a second mounting groove. The first thermal insulation material is installed on the groove wall of the first mounting groove, and the second thermal insulation material is installed on the groove wall of the second mounting groove. The first thermal insulation material and the second thermal insulation material can be made of diphenylethylene compounds, which can undergo photoisomerization. After the first protective plate 5 and the second protective plate 8 are opened, the first thermal insulation material and the second thermal insulation material can begin to absorb the heat of sunlight. When the first protective plate 5 and the second protective plate 8 are closed, the first thermal insulation material and the second thermal insulation material release heat under dim conditions, thereby protecting the photovoltaic panel 2 from reducing its service life in a cold environment, so as to realize passive thermal insulation by utilizing the photothermal properties of the thermal insulation material.

[0043] In this embodiment, the first driving assembly 3 includes a first driving module 31 and a first transmission module 32, the first transmission module 32 includes a first gear 321, a second gear 322, a first transmission rod 323, a first slide bar 324, a first slider 325 and a first connecting rod 326, the first gear 321 is rotatably connected to the frame 1, the second gear 322 is rotatably connected to the frame 1 and is transmission-connected to the first gear 321, the second gear 322 is connected to the first transmission rod 323, the first transmission rod 323 is provided with a first slide groove 3231, the frame 1 is provided with a first guide groove 11, the first slider 325 is slidably arranged in the first guide groove 11, the first slide bar 324 is connected to the first slider 325, and one end of the first slide bar 324 is slidably arranged in the first slide groove 3231, one end of the first connecting rod 326 is connected to the first slider 325, the other end of the first connecting rod 326 is rotatably connected to the first protective plate 5, and the first cleaning assembly 4 is connected to one end of the first connecting rod 326. Specifically, the first driving module 31 drives the first gear 321 to rotate a quarter of a circle, the first gear 321 drives the second gear 322 to rotate a half circle, the second gear 322 drives the first transmission rod 323 to swing, the first transmission rod 323 drives the first slide bar 324 to move, while the first slide bar 324 moves along the first slide groove 3231, the first slide bar 324 drives the first slider 325 to move along the first guide groove 11, the first slider 325 drives the first connecting rod 326 to move, the first connecting rod 326 drives the first protective plate 5 to move, when the first protective plate 5 is away from the photovoltaic panel 2, the first protective plate 5 will swing under its own gravity, so that the first protective plate 5 can be fully opened to reveal the photovoltaic panel 2. The first connecting rod 326 can also drive the first cleaning component 4 to move, so that the first cleaning component 4 can clean the photovoltaic panel 2 as the first protective plate 5 is opened, thereby improving the photoelectric conversion efficiency.

[0044] Furthermore, the frame 1 is further provided with a first avoidance groove 12 and a second avoidance groove 13 which are in communication with the first guide groove 11, the first avoidance groove 12 is used to avoid the first slide bar 324, the second avoidance groove 13 is used to avoid the first connecting rod 326, and the first protective plate 5 is provided with a third avoidance groove 51, the third avoidance groove 51 is used to avoid the first connecting rod 326. In this way, the first slide bar 324 will not interfere with the frame 1, the first connecting rod 326 will not interfere with the frame 1, and the first connecting rod 326 will not interfere with the first protective plate 5.

[0045] In one embodiment, if Figure 3 and Figure 4As shown, the first driving module 31 includes a first frame 311, a first magnetic member 312, a second magnetic member 313, a first electromagnet 314 and a first driving rod 315. The first frame 311 is provided with a first moving groove 3111, the first magnetic member 312 is fixed at one end of the first moving groove 3111, the second magnetic member 313 is fixed at the other end of the first moving groove 3111, the first electromagnet 314 is slidably disposed in the first moving groove 3111, and the first electromagnet 314 and the first driving rod 315 are rotated. The first driving rod 315 is also connected to the eccentric part of the first gear 321, the first electromagnet 314 is energized, the first magnetic part 312 and the first electromagnet 314 are attracted to each other, and the second magnetic part 313 and the first electromagnet 314 are repelled from each other, so that the first electromagnet 314 can move from the second magnetic part 313 along the first movable groove 3111 toward the direction of the first magnetic part 312, the first electromagnet 314 drives the first driving rod 315 to move, and the first driving rod 315 drives the first transmission module 32 to move. Since the first protective plate 5 is made of a transparent material, and the first thermal insulation material can be arranged at intervals on the first protective plate 5, when the photovoltaic panel 2 receives sunlight, a portion of the electricity of the photovoltaic panel 2 will be transmitted to the first electromagnet 314, the first electromagnet 314 generates magnetism, the first magnetic part 312 and the first electromagnet 314 are attracted to each other, and the second magnetic part 313 and the first electromagnet 314 repel each other, so that the first electromagnet 314 can move from the second magnetic part 313 along the first movable groove 3111 toward the direction of the first magnetic part 312, the first electromagnet 314 drives the first driving rod 315 to move, and the first driving rod 315 drives the first gear 321 to rotate.

[0046] When there is no sunlight at night, the photovoltaic panel 2 cuts off the power to the first electromagnet 314, and the first electromagnet 314 loses its magnetism. Due to the gravity of the first driving rod 315 and the suction force of the second magnetic member 313, the first electromagnet 314 can return to its initial position, thereby driving the first driving rod 315 to reset. The first driving rod 315 then drives the first gear 321 to rotate in the opposite direction to achieve the reset of the first protective plate 5 and the first cleaning component 4.

[0047] Of course, in other embodiments, the first magnetic member 312 can be removed. After the first electromagnet 314 is energized, the second magnetic member 313 repels the second magnetic member 313, and the repulsive force is greater than the gravity of the first drive rod 315, the first transmission module 32, the first protective plate 5 and the first cleaning component 4, so that the first drive rod 315 drives the first gear 321 to rotate a quarter of a turn to open the first protective plate 5. When there is no sunlight at night, the photovoltaic panel 2 cuts off the power to the first electromagnet 314, the first electromagnet 314 loses its magnetism, and due to the gravity of the first drive rod 315 and the suction force of the second magnetic member 313, the first electromagnet 314 can be restored to the initial position, thereby driving the first drive rod 315 to reset, and the first drive rod 315 then drives the first gear 321 to rotate in the opposite direction to achieve the reset of the first protective plate 5 and the first cleaning component 4.

[0048] Furthermore, the cross-sectional dimension of the end of the first driving rod 315 close to the first electromagnet 314 is larger than the cross-sectional dimension of the end of the first driving rod 315 away from the first electromagnet 314. In this way, the first driving rod 315 can drive the first gear 321 to reset after the first electromagnet 314 is powered off.

[0049] In one embodiment, if Figure 4 As shown, the first cleaning assembly 4 includes a first rod body 41 and a plurality of first cleaning brushes 42, the first rod body 41 is connected to the first connecting rod 326, and the plurality of first cleaning brushes 42 are arranged at intervals along the extension direction of the first rod body 41. The interval positions of the plurality of first cleaning brushes 42 are the same as the intervals between the panels of the photovoltaic panel 2. In this way, dust and other dirt on the photovoltaic panel 2 can be cleaned more thoroughly.

[0050] It should be noted that, in the relevant embodiment, the second driving assembly 6 is the same as the first driving assembly 3, the second cleaning assembly 7 is the same as the first cleaning assembly 4, and the second protective plate 8 is the same as the first protective plate 5, so they are not repeated here.

[0052] In this embodiment, the frame 1 is also provided with a fourth avoidance groove and a fifth avoidance groove connected to the second guide groove, the fourth avoidance groove is used to avoid the second sliding rod, the fifth avoidance groove is used to avoid the second connecting rod, and the second protective plate 8 is provided with a sixth avoidance groove, and the sixth avoidance groove is used to avoid the second connecting rod.

[0053] Furthermore, the second driving module includes a second frame, a third magnetic part, a fourth magnetic part, a second electromagnet and a second driving rod. The second frame is provided with a second movable groove, the third magnetic part is fixed at one end of the second movable groove, the fourth magnetic part is fixed at the other end of the second movable groove, the second electromagnet is slidably arranged in the second movable groove, the second electromagnet is rotatably connected to the second driving rod, and the second driving rod is also connected to the eccentric point of the third gear.

[0054] Furthermore, a cross-sectional dimension of an end of the second driving rod close to the second electromagnet is greater than a cross-sectional dimension of an end of the second driving rod far from the second electromagnet.

[0055] The second cleaning assembly 7 includes a second rod body and a plurality of second cleaning brushes. The second rod body is connected to a second connecting rod. The plurality of second cleaning brushes are arranged at intervals along an extending direction of the second rod body.

[0056] The technical features of the above-described embodiments may be arbitrarily combined.
