[0028] like Figure 1 and Figure 5As shown, the photovoltaic power generation device of this embodiment includes: a support structure 10, a photovoltaic assembly 20 and a first spectrum enhancement plate 30. The photovoltaic assembly 20 is arranged on the support structure 10. The first spectrum enhancement plate 30 is movably arranged on the support structure 10 and has a first extended position and a first retracted position. When the first spectrum enhancement plate 30 is in the first extended position, the first spectrum enhancement plate 30 is located at a position protruding from the photovoltaic assembly 20, and the first spectrum enhancement plate 30 can enhance the light of the first wavelength. When the first spectrum enhancement plate 30 is in the first retracted position, the first spectrum enhancement plate 30 is located below the photovoltaic assembly 20.

[0029] Applying the technical solution of this embodiment, the photovoltaic power generation device includes a support structure 10, a photovoltaic module 20 and a first spectrum enhancement plate 30. The photovoltaic module 20 is arranged on the support structure 10. The first spectrum enhancement plate 30 is movably arranged on the support structure 10, and the first spectrum enhancement plate 30 has a first extended position protruding from the photovoltaic module 20 and a first retracted position located below the photovoltaic module 20. Through the above-mentioned setting, the photovoltaic module 20 can convert light energy into electrical energy. When the first spectrum enhancement plate 30 is in the first extended position, the first spectrum enhancement plate 30 can enhance the light of the first wavelength, so that after the light of the first wavelength is irradiated to the plant, it can promote the growth of the plant, avoiding the problem that the photovoltaic module 20 blocks the sunlight and affects the growth of the plant. When the first spectrum enhancement plate 30 is in the first retracted position, it can move below the photovoltaic module 20. Therefore, the technical solution of this embodiment effectively solves the problem that the photovoltaic power generation device in the related art will block the sunlight and affect the growth of the plant.

[0030] When the first spectrum enhancement plate 30 is in the first retracted position, the first spectrum enhancement plate 30 can be protected by the photovoltaic assembly 20 to avoid being damaged.

[0031] like Figure 3 As shown, in this embodiment, the photovoltaic power generation device also includes a second spectrum enhancement plate 40 movably arranged on the support structure 10, the second spectrum enhancement plate 40 is overlapped with the first spectrum enhancement plate 30, and the second spectrum enhancement plate 40 has a second extended position and a second retracted position. When the second spectrum enhancement plate 40 is in the second extended position, the second spectrum enhancement plate 40 moves to the outside of the support structure 10, and the second spectrum enhancement plate 40 can enhance the light of the second wavelength. When the second spectrum enhancement plate 40 is in the second retracted position, the second spectrum enhancement plate 40 moves into the support structure 10. When the second spectrum enhancement plate 40 is in the second extended position, the second spectrum enhancement plate 40 can enhance the light of the second wavelength, thereby promoting the growth of plants. The second spectrum enhancement plate 40 is overlapped with the first spectrum enhancement plate 30, so that when the first spectrum enhancement plate 30 is in the first retracted position and the second spectrum enhancement plate 40 is in the second retracted position, the space occupation can be reduced.

[0032] It should be noted that the moving direction of the first spectrum enhancement plate 30 is the same as the moving direction of the second spectrum enhancement plate 40. Frames are provided on the peripheries of the first spectrum enhancement plate 30 and the second spectrum enhancement plate 40. The first spectrum enhancement plate 30 includes a first transparent plate and a first light-converting agricultural film provided on a side of the first transparent plate away from the photovoltaic assembly, and the second spectrum enhancement plate 40 includes a second transparent plate and a second light-converting agricultural film provided on a side of the second transparent plate away from the photovoltaic assembly.

[0033] The light of the first wavelength is blue light, and the light of the second wavelength is red light. The first spectrum enhancement plate 30 enhances the light of the first wavelength by converting the ultraviolet light and green light in the sunlight that have no effect on plant growth into the blue light required for plant photosynthesis. The second spectrum enhancement plate 40 enhances the light of the second wavelength by converting the ultraviolet light and green light in the sunlight that have no effect on plant growth into the blue light required for plant photosynthesis. The first spectrum enhancement plate 30 and the second spectrum enhancement plate 40 of this embodiment can be prepared separately by the method mentioned in CN117510923A. Of course, the wavelengths that can be enhanced by the first spectrum enhancement plate and the wavelengths that can be enhanced by the second spectrum enhancement plate can be replaced by different spectrum enhancement plates according to the type of plant.

[0034] The first spectrum enhancement plate 30 and the second spectrum enhancement plate 40 can also be the luminous optical elements mentioned in CN110915001A. Of course, the first spectrum enhancement plate 30 and the second spectrum enhancement plate 40 can also be prepared by other technical solutions in the prior art, or adopt a structure in the prior art that can achieve light enhancement of a specific wavelength.

When the photovoltaic power generation device is in the initial state, the first spectrum enhancement plate 30 is in a first retracted position, and the second spectrum enhancement plate 40 is in a second retracted position. When the photovoltaic power generation device is in the filtering state, the first spectrum enhancement plate 30 is in a first extended position or the second spectrum enhancement plate 40 is in a second extended position. The above-mentioned setting enables the first spectrum enhancement plate 30 to be moved to the first extended position or the second spectrum enhancement plate 40 to be moved to the second extended position according to the need to promote plant growth, thereby promoting plant growth.

[0040] The second frame 132 includes a third support beam disposed on the first connecting oblique rod 133 and a fourth support beam disposed on the second connecting oblique rod 134.

[0056] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the devices or elements referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention. The directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0057] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0058] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present invention.

[0059] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
