It is to be understood that the first driving means 220 is capable of driving the outer louver 210 to rotate at least 180 °.

More specifically, in the case of an arrangement in which the first driving means 220 individually drives each of the outer louvers 210, the first driving means 220 may be only a rotary motor; in the case that the first driving device 220 drives the plurality of outer louvers 210 synchronously, the first driving device 220 may be a rotating motor and a synchronous moving mechanism, wherein the synchronous mechanism includes, but is not limited to, a chain, a belt, and the like.

Generally speaking, the photovoltaic shutter of this application, its working process as follows:

in the open state of the outer louvers 210, according to the change of the solar altitude, the first driving device 220 drives each outer louver 210 to rotate so as to enable the photovoltaic panel 211 to obtain the maximum power generation efficiency;

in the closed state of the outer louver 210, the second driving device 420 drives the cleaning brush 410 to move and contact with the dust screen 300 and/or the outer louver 210, so as to clean dust on the dust screen 300 and the outer louver 210, keep the dust screen 300 clean to ensure ventilation efficiency, and keep the photovoltaic panels 211 on the outer louver 210 clean to ensure power generation efficiency.

It is understood that in some embodiments of the present application, the outer louvers 210 are linked, and the first driving device 220 drives the outer louvers 210 to rotate synchronously. For example, each outer louver 210 is linked by a link mechanism, or each outer louver 210 is driven to rotate by the above belt synchronizing mechanism or chain synchronizing mechanism.

Referring to fig. 5, the first driving device 220 is taken as a chain synchronization mechanism as an example. The first driving means 220 includes a first rotating motor 221, a first sprocket 223 disposed on the shaft of each of the outer louvers 210, a second sprocket 422 disposed on the output shaft of the first rotating motor 221, and a chain engaged with each of the first sprocket 223 and the second sprocket 422.

Specifically, the first sprocket 223 may be disposed at only one end of the rotation shaft of each outer louver 210, or may be disposed at both ends of the rotation shaft of the outer louvers 210; similarly, the first rotating motor 221 may be disposed only one and located at one side of the outer louver assembly 200, or may be disposed two and located at two sides of the outer louver assembly 200, respectively.

When the first rotating motor 221 rotates, it drives the first chain 222 to rotate, so that the first chain 222 drives each first chain wheel 223 to rotate, thereby realizing the rotation of the outer louvers 210, so that each outer louver 210 can rotate synchronously to completely open or close the opening of the frame 100, or each outer louver 210 rotates along with the change of the sun height, so that the photovoltaic panel 211 on the outer louver 210 obtains the maximum power generation efficiency.

It will be appreciated that, with reference to fig. 1 to 3, in other embodiments of the present application, each outer louver 210 is separately rotatably disposed, and the first driving means 220 includes a plurality of rotating motors, each rotating motor being disposed corresponding to each outer louver 210 for rotation of each outer louver 210.

It is understood that, on the basis of any of the above embodiments, the photovoltaic panel 211 is disposed on one side surface or opposite side surfaces of the outer louver 210.

Specifically, when the photovoltaic panels 211 are disposed on the opposite surfaces 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 located on the outer louver 210 toward the inner side of the frame 100 can be cleaned by the cleaning brush 410, and meanwhile, the photovoltaic panels 211 on the outer louver 210 toward the outer side of the frame 100 can still receive sunlight to maintain the power generation state. Similarly, after the photovoltaic panel 211 on one side of the outer louver 210 is cleaned, the first driving device 220 drives the outer louver 210 to rotate to the inside of the frame body 100 where the photovoltaic panel 211 is not cleaned, so that alternate cleaning of the photovoltaic panel 211 is realized, the influence on the power generation of the photovoltaic panel 211 is small, and the power generation efficiency of the photovoltaic louver is improved.

The outer louver 210 is arranged in such a way that the photovoltaic panel 211 on any one side of the outer louver 210 does not affect the power generation of the photovoltaic panel 211 on the other side when being cleaned, so that the photovoltaic louver is suitable for an environment with good sunshine conditions and large dust and sand.

In some embodiments of the present application, the second driving device 420 may be a chain driving device disposed in a height or width direction of the frame body 100, which includes a second rotating motor 421, a second sprocket 422, and a second chain 423, and the cleaning brush 410 is disposed on the second chain 423. For example, referring to fig. 1, fig. 1 is a schematic view of the chain drive device disposed in the height direction of the frame 100.

Specifically, the second driving device 420 may be provided in a single set or in two sets. When two sets of second driving devices 420 are provided, the two sets of second driving devices 420 are respectively provided on two opposite inner sides of the frame 100, the cleaning brush 410 is erected between the second chains 423 of the two sets of second driving devices 420, and the two sets of second driving devices 420 simultaneously drive the cleaning brush 410 to move.

Further, the interval between the two parallel sections of the second chain 423 is matched with the interval between the photovoltaic panel 211 and the dust screen 300 on the outer louver 210 in the closed state. As such, when the second chain 423 rotates, the cleaning brush 410 can maintain contact with the dust screen 300 and/or the photovoltaic panel 211 to secure a cleaning effect.

Further, only one cleaning brush 410 may be provided, or two cleaning brushes may be provided. In the case that one cleaning brush 410 is provided, the second chain 423 drives the cleaning brush 410 to move along the circular track of the chain, that is, the dust screen 300 and the photovoltaic panel 211 are sequentially cleaned. In the case that the cleaning brushes 410 are provided with two, the two cleaning brushes 410 are respectively provided on two parallel sections of the second chain 423, so that when the second rotating motor 421 drives the second chain 423 to rotate, the cleaning brush 410 in contact with the dust screen 300 moves upward, and the cleaning brush 410 in contact with the photovoltaic panel 211 moves downward in synchronization; or conversely, the cleaning brush 410 in contact with the dust screen 300 moves downward, and the cleaning brush 410 in contact with the photovoltaic panel 211 moves upward in synchronization, so that the cleaning efficiency can be improved.

Thus, when the second rotating motor 421 rotates, the nut 427 is driven by the lead screw 426 to move linearly along the guiding structure, so as to drive the cleaning brush 410 to move.

Further, only one second driving device 420 may be provided on one side of the opening of the housing 100, or two second driving devices may be provided on opposite sides of the opening of the housing 100.

Further, in a state where each outer louver 210 is closed, both sides of the cleaning brush 410 abut against the dust screen 300 and the outer louver 210 at the same time. In this way, when the second rotating motor 421 rotates, the lead screw 426 drives the nut 427 to move linearly along the length direction of the lead screw 426 (i.e. the height direction of the frame 100), and the nut 427 drives the cleaning brush 410 to move reciprocally along the height direction of the frame 100; further, as the brush bodies are arranged on the two opposite side surfaces of the cleaning brush 410, when the cleaning brush 410 moves, the brush bodies on the two side surfaces of the cleaning brush are respectively contacted with the dust screen 300 and the photovoltaic panels 211 on the outer shutter 210, so that the simultaneous cleaning operation of the dust screen 300 and the photovoltaic panels 211 on the outer shutter 210 is realized, and the cleaning efficiency is high.
