[0027] Tea trees like light and tolerate shade. High-quality tea production requires reasonable light and shade to improve tea yield and quality. The light intensity at noon often exceeds the light saturation point of tea trees, and shade coverings (mainly shade nets) are usually used, which increases operating costs.

[0028] Some tea gardens will install photovoltaic devices and use the photovoltaic components of the devices for shade. This will increase the power generation income while meeting the growth needs of tea trees, reduce costs, increase efficiency and maximize the use of natural resources.

[0029] In the known technology, photovoltaic modules are installed in an interval manner. There is enough interval between two adjacent photovoltaic modules, and sunlight can shine from the interval to the tea trees under the photovoltaic modules to ensure that the tea trees can obtain sufficient light, thereby obtaining tea leaves of better quality. In the above technology, photovoltaic modules cannot be set too densely, otherwise the vegetation under the photovoltaic modules will find it difficult to obtain sufficient light, affecting the normal growth of the vegetation. Therefore, the installation capacity of photovoltaic modules is small, and the benefits of photovoltaic power generation will be reduced.

[0030] In order to solve the problem of insufficient illumination of vegetation when the existing photovoltaic device is installed above the vegetation, the utility model provides a photovoltaic device.

[0031] like Figure 1 and Figure 2 As shown, the photovoltaic device is installed above the vegetation, and includes a photovoltaic support 1, a photovoltaic module 2 and a light guide module 3. The photovoltaic support 1 is fixed above the ground, and the photovoltaic modules 2 and the light guide module 3 are both fixed to the photovoltaic support 1. The photovoltaic modules 2 are arranged in rows along the first direction X, and the photovoltaic modules 2 arranged in rows are arranged continuously without gaps to ensure the installation capacity of the photovoltaic modules 2. The light guide module 3 is arranged near the photovoltaic modules 2, and the light guide module 3 can collect sunlight and diffuse the sunlight to the bottom of the photovoltaic modules 2 to supplement the illumination of at least part of the vegetation shielded by the photovoltaic modules 2, thereby ensuring that the vegetation shielded by the photovoltaic modules 2 can also grow normally.

[0032] like Figure 2 and Figure 3 As shown, the light guide assembly 3 includes a skylight 31 and a diffuser 32. The skylight 31 is located above the diffuser 32. The skylight 31 is configured to collect light and converge the light to the diffuser 32. The diffuser 32 is configured to diffuse the light received from the skylight 31 to the bottom of the photovoltaic assembly 2. Specifically, the top of the skylight 31 is convex and has a polyhedral structure, which can collect light from multiple angles. The skylight 31 is in the shape of an elongated strip, extending along the first direction X, with a length of 1m to 1.5m, a width of 30cm to 50cm, and a height of 20cm to 30cm. The lower surface of the diffuser 32 is convex downward, and the diffusion angle is -30° to 30°, so as to ensure that the light emitted from the diffuser 32 can be evenly irradiated to the bottom of the photovoltaic assembly 2, thereby meeting the growth requirements of the vegetation shaded by the photovoltaic assembly 2. The diffuser 32 has a length of 1 m to 1.5 m, a width of 30 cm to 50 cm, and a height of 20 cm to 30 cm. As a preferred solution, the length and width of the diffuser 32 are the same as those of the daylighting cover 31 .

[0033] The light guide assembly 3 further includes hanging ears 33, which are arranged at four corners of the light guide assembly 3. The hanging ears 33 are connected to the photovoltaic assembly 2 or the photovoltaic bracket 1 to fix the light guide assembly 3.

[0034] In some possible examples, a light-transmitting sheet 34 is disposed between the light-collecting cover 31 and the diffuser 32, and the light-transmitting sheet 34 is configured to transmit light required for photosynthesis of vegetation, such as red and blue light, where red and blue light are the spectra that can be absorbed by vegetation for photosynthesis. Of course, in other embodiments, for different types of vegetation, the absorbed spectra are different, and the light-transmitting sheet 34 can be configured to transmit the required type of light according to the needs.

[0035] In some examples, combined Figure 2As shown, at least two rows of photovoltaic components 2 are arranged, and at least two rows of photovoltaic components 2 are arranged along the second direction Y, and the height of each row of photovoltaic components 2 increases successively along the second direction Y. The light guide component 3 is located between two adjacent rows of photovoltaic components 2, and the light guide component 3 is configured to diffuse the collected light to the bottom of two photovoltaic components 2 adjacent to the light guide component 3, so as to improve the utilization efficiency of the light guide component 3, and at the same time, the photovoltaic components 2 can be arranged more densely in the second direction Y to obtain a higher installation capacity.

[0036] The first direction X is generally set to be east-west, and the second direction Y is generally set to be north-south. The photovoltaic module 2 is tilted and faces south with an inclination angle of 0-50° to achieve optimal power generation efficiency. The spacing between two adjacent rows of photovoltaic modules 2 in the second direction Y is 30cm to 50cm to facilitate the placement of the light guide module 3. For example, the specifications of the photovoltaic module 2 are 2384mm*1303mm*35mm, which has a good sunshade effect in summer.

[0037] In some possible examples, the light guide assembly 3 is arranged horizontally. Specifically, in two adjacent rows of photovoltaic assemblies 2, the upper edge of the first row of photovoltaic assemblies 2 is flush with the lower edge of the second row of photovoltaic assemblies 2, the light guide assembly 3 is located between the upper edge of the first row of photovoltaic assemblies 2 and the lower edge of the second row of photovoltaic assemblies 2, and the hanging ears 33 of the light guide assembly 3 are respectively hung on the upper edge of the first row of photovoltaic assemblies 2 and the lower edge of the second row of photovoltaic assembly parts, so that the light guide assembly 3 is arranged horizontally.

[0038] In some possible implementations, such as Figure 4 As shown, the light guide assembly 3 is arranged between the photovoltaic assemblies 2 in a single row. The length direction of the light guide assembly 3 is consistent with the length direction or width direction of the photovoltaic assembly 2, and the inclination direction of the light guide assembly 3 is consistent with the inclination direction of the photovoltaic assembly 2, that is, it is inclined along the second direction Y. At this time, the light guide assembly 3 can collect sunlight and diffuse the sunlight to the bottom of the photovoltaic assembly 2 to supplement the illumination of at least part of the vegetation shielded by the photovoltaic assembly 2. In addition, since the inclination angle of the light guide assembly 3 is consistent with the inclination angle of the photovoltaic assembly 2, the light diffused by the light guide assembly 3 can better cover the vegetation shielded by the photovoltaic assembly 2.

[0039] For example, along the first direction X, a light guide assembly 3 is arranged between every two photovoltaic assemblies 2, and the light diffused by one light guide assembly 3 can cover the vegetation shaded by the two photovoltaic assemblies 2 adjacent to the light guide assembly 3. In this way, the number of light guide assemblies 3 used can be reduced, and the installed capacity of the photovoltaic assembly 2 can also be increased.

[0040] like Figure 1 and Figure 2As shown, the photovoltaic support 1 includes a column 11, a fixing component 12 and a supporting component 13. The column 11 is fixed on the ground, the fixing component 12 is located above the column 11, and the supporting component 13 is connected to the fixing component 12 and the column 11 to support the fixing component 12.

[0041] A plurality of columns 11 are provided, and the columns 11 are spaced apart along the first direction X, and the weight of the fixing assembly 12, the supporting assembly 13 and the photovoltaic assembly 2 are effectively shared by the plurality of columns 11 to stably support the photovoltaic assembly 2. In a specific example of the present utility model, the height of the column 11 is 1.5m to 1.8m.

[0042] The fixing assembly 12 includes a longitudinal beam 122 extending along the first direction X and extending in a direction perpendicular to the cross beam. The cross beam and the longitudinal beam 122 are fixedly connected and are parallel to the photovoltaic assembly 2. The photovoltaic assembly 2 is fixed to the cross beam and the longitudinal beam 122. The cross beam includes a long cross beam (not shown in the figure) and a short cross beam 121. The long cross beam constitutes the main skeleton of the fixing assembly 12 to ensure the continuity of the fixing assembly 12. The short cross beam 121 and the long cross beam are connected by the longitudinal beam 122. Multiple short cross beams 121 are at different heights. The short cross beam 121 and the longitudinal beam 122 are mainly used to fix the photovoltaic assembly 2. In the example of the present utility model, the length of the short cross beam 121 is 1.5m to 2m, and the height difference between two adjacent short cross beams 121 is 20cm to 30cm.

[0043] In combination Figure 5 and Figure 6 As shown, the support assembly 13 includes a first arc-shaped support member 131 and a second arc-shaped support member 132. The second arc-shaped support member 132 is located inside the first arc-shaped support member 131 and is arranged concentrically with the first arc-shaped support member 131. The first arc-shaped support member 131 and the second arc-shaped support member 132 are both fixed below the fixing assembly 12. Specifically, both ends of the first arc-shaped support member 131 and both ends of the second arc-shaped support member 132 are fixedly connected to beams at different heights. A sliding sleeve 111 is provided near the top of the column 11, and the second arc-shaped support member 132 is slidably connected to the sliding sleeve 111; the first arc-shaped support member 131 is detachably fixedly connected to the column 11 through a connecting member 14. After the connector 14 is disassembled, the second arc-shaped support member 132 can be slid relative to the sliding sleeve 111, thereby changing the inclination angle of the fixing assembly 12 and the photovoltaic assembly 2, and then the first arc-shaped support member 131 and the column 11 are fixed by the connector 14, so that the first arc-shaped support member 131, the second arc-shaped support member 132 and the column 11 remain stable. In the example of the utility model, the diameter of the first arc-shaped support member 131 is 1.5m to 2m, and the diameter of the second arc-shaped support member 132 is 0.8m to 1.2m.

[0044] In some examples, the first arc support member 131 and the second arc support member 132 are square tubes, and the sliding sleeve 111 includes at least one U-shaped buckle (for example, two). The U-shaped buckle is fixed to the column 11, and the second arc support member 132 passes through the U-shaped buckle, so that the second arc support member 132 can slide in the U-shaped buckle. The first arc support member 131 is provided with a plurality of adjustment holes 1311 arranged at intervals along the arc track, and the arc track arranged by the adjustment holes 1311 is concentrically arranged with the first arc support member 131, and a socket (not shown in the figure) is correspondingly provided on the column 11, and the connecting member 14 is a pin, which is configured to be inserted into the adjustment hole 1311 and the socket of the column 11 to fix the first arc support member 131 and the column 11.

[0045] By adjusting the adjustment hole 1311 corresponding to the plug hole of the column 11, the inclination angle of the fixed component 12 and the photovoltaic component 2 can be changed. Specifically, when the inclination angle of the photovoltaic component 2 and the fixed component 12 needs to be adjusted, the connector 14 is pulled out from the adjustment hole 1311 and the plug hole, and then the first arc support member 131 and the second arc support member 132 are rotated to make the second arc support member 132 slide in the sliding sleeve 111. At this time, the first arc support member 131 rotates with the second arc support member 132 to change the adjustment hole 1311 corresponding to the plug hole of the column 11. After the inclination angle of the photovoltaic component 2 and the fixed component 12 is adjusted appropriately, the connector 14 is inserted into the plug hole and the adjustment hole 1311 corresponding to the plug hole, so as to fix the first arc support member 131, the second arc support member 132 and the column 11.

[0046] For example, the number of adjustment holes 1311 can change the angle of the photovoltaic assembly 2 from 0° (only one adjustment hole 1311 is provided) to 35° (a plurality of adjustment holes 1311 are provided).

[0047] It should be noted that regarding the sliding sleeve 111, although in the specific example of the present invention, the sliding sleeve 111 includes at least one U-shaped buckle, this is not a specific limitation of the present invention. Without departing from the principle of the present invention, in other examples, the sliding sleeve 111 can adopt other structures to enable the second arc-shaped support member 132 to slide relative to the sliding sleeve 111 to change the inclination angle of the fixed component 12 and the photovoltaic component 2.

[0048] It should be noted that the connector 14 is a latch in the specific example of the present invention, but this is not a specific limitation of the present invention. The connector 14 can be used with other structural members (such as calipers, etc.) to detachably fix the first arc-shaped support member 131 and the column 11. After the connector 14 is removed, the first arc-shaped support member 131 and the column 11 are separated, and the second arc-shaped support member 132 can be slid relative to the sleeve 111 to change the inclination angle of the fixed assembly 12 and the photovoltaic assembly 2, and then the connector 14 is used to fix the first arc-shaped support member 131 and the column 11, so as to fix the first arc-shaped support member 131, the second arc-shaped support member 132 and the column 11.

[0049] Of course, the specific structure of the support component 13 is not limited to the specific example of the present invention. In other embodiments, the support component 13 may also adopt other structures as long as it can connect the support component 13 and the column 11 to support the fixing component 12.

[0050] In summary, the specific implementation principle of the utility model is:

[0051] After the sunlight irradiates the photovoltaic device, part of the sunlight irradiates the photovoltaic module 2 for power generation, and part of the sunlight irradiates the light-collecting cover 31 of the light-guiding component 3. The light irradiated to the light-collecting cover 31 is gathered by the light-collecting cover 31 to the diffuser 32, and diffused by the diffuser 32 to the bottom of the photovoltaic module 2 to supplement the illumination of at least part of the vegetation shielded by the photovoltaic module 2, thereby ensuring that the vegetation shielded by the photovoltaic module 2 can also grow normally. Since the light-guiding component 3 can supplement the illumination of at least part of the vegetation shielded by the photovoltaic module 2, ensuring that the plants located under the photovoltaic module 2 can also grow normally, the photovoltaic modules 2 can be arranged more densely, thereby increasing the installed capacity of the photovoltaic modules 2.

[0052] So far, the technical solution of the present invention has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
