Description

Technical Field

[0001] This utility model relates to the field of photovoltaic equipment technology, specifically to a vertically installed photovoltaic device. Background Technology

[0002] Vertically installed photovoltaic (PV) modules generate more power in the morning and evening, and less at midday. In traditional south-facing PV power plants, installing vertically installed PV modules can increase the power generation of the PV power plant, with only a small increase at midday, resulting in a more balanced power generation throughout the day and increasing the utilization hours of the PV power plant.

[0003] The vertical installation mode means that the ground near the photovoltaic modules receives sunlight for a short period of time, less than half of the day, which is not conducive to the growth of sun-loving plants, such as food crops and pasture.

[0004] This application was designed to ensure that all ground surfaces of vertically installed photovoltaic systems receive direct sunlight, except during the periods in the early morning (approximately 1 hour) and late afternoon (approximately 1 hour) when they are shaded by a row of adjacent photovoltaic modules. Utility Model Content

[0005] Therefore, this utility model provides a vertically installed photovoltaic device to solve the above-mentioned problems in the prior art. To achieve the above objective, this utility model provides the following technical solution: According to a first aspect of this utility model, a vertically installed photovoltaic device includes photovoltaic modules arranged at intervals. The lower part of each photovoltaic module is a translucent refractive plate or film. Both the photovoltaic module and the translucent refractive plate or film extend vertically upward. All photovoltaic modules are fixed to the ground by pillars. The top of the pillars is connected by a fixed traction cable, which also serves to reinforce against wind. Both ends of the fixed traction cable are fixed to the ground.

[0006] Furthermore, each group of photovoltaic modules and the reflective plate is located in the same vertical plane.

[0007] Furthermore, the refractive plate is a Fresnel mirror.

[0008] Furthermore, the serrated surface of the Fresnel mirror that constitutes the refractive plate is either arc-shaped or straight-shaped.

[0009] Furthermore, several through holes are provided on the translucent plate or membrane to reduce wind resistance.

[0010] Furthermore, the through holes on the refracting plate or film are evenly distributed.

[0011] Furthermore, the through hole can be a round hole or a polygonal hole.

[0012] Furthermore, the fixed traction cable includes a horizontal fixed traction cable and an inclined fixed traction cable. The tops of adjacent supports are connected by the horizontal fixed traction cable, and the tops of the supports at the ends are fixed to the ground by the inclined fixed traction cable.

[0013] Furthermore, the angle between the inclined fixed traction cable and the ground is approximately 45°.

[0014] The present invention has the following advantages: By using a vertically installed photovoltaic device of the present invention, the photovoltaic module is raised to a certain height, and a translucent plate or film is installed in the space below the photovoltaic module. Except for the early morning (about 1 hour) and late afternoon (about 1 hour), at almost all times, on days with direct sunlight, all the ground in the farmland where the photovoltaic module is laid can receive direct sunlight.

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] Example 1

[0020] like Figures 1 to 2 As shown in the first aspect embodiment of the present invention, a vertically installed photovoltaic device includes photovoltaic modules 1 arranged at intervals. The lower part of each photovoltaic module 1 is a transparent refractive plate 2. Both the photovoltaic module 1 and the transparent refractive plate 2 extend vertically upward. All photovoltaic modules 1 are fixed to the ground by support columns 5. The top of the support columns 5 is connected by a fixed traction cable and plays a role in wind protection and reinforcement. The two ends of the fixed traction cable are fixed to the ground.

[0021] The technical effect achieved by the above embodiment is as follows: by using a vertically installed photovoltaic device in this embodiment, the photovoltaic module is raised to a certain height, and a transmissive plate or film is installed in the space below the photovoltaic module. Except for about 1 hour in the early morning and about 1 hour in the late afternoon, at almost all times, in weather with direct sunlight, all the ground in the farmland where the photovoltaic module is laid can receive direct sunlight.

[0022] Example 2

[0023] like Figures 1 to 2 As shown, a vertically installed photovoltaic device includes all the contents of Embodiment 1, except that each photovoltaic module 1 and the transmissive plate 2 are located in the same vertical plane.

[0024] The technical effect achieved by the above embodiments is that by placing each group of photovoltaic modules 1 and the transmissive plate 2 in the same vertical plane, the standardization of structural installation is improved and the stability between components is guaranteed.

[0025] Example 3

[0026] like Figures 1 to 2 As shown, a vertically mounted photovoltaic device includes all the contents of Embodiment 2, except that the refractive plate 2 is a Fresnel mirror.

[0027] Optionally, the serrated surface of the Fresnel mirror constituting the refractive plate 2 can be arc-shaped or straight-shaped.

[0028] The technical effect achieved by the above embodiments is that the refractive plate or film is a Fresnel mirror structure. The serrated surface of the Fresnel mirror is arc-shaped or straight-lined, so that the direct sunlight passing through the Fresnel mirror can illuminate the area where the direct sunlight is blocked by the photovoltaic module, which is beneficial to the even distribution of direct sunlight on the ground.

[0029] Example 4

[0030] like Figures 1 to 2 As shown, a vertically installed photovoltaic device includes all the contents of Embodiment 3, except that the translucent plate 2 has several through holes to reduce wind resistance.

[0031] Optionally, the through holes on the refracting plate 2 are evenly distributed.

[0032] Optionally, the through hole can be a round hole or a polygonal hole.

[0033] The technical effects achieved by the above embodiments are as follows: the vertically installed translucent plate 2 can be a perforated translucent plate or film to improve wind resistance and allow more sunlight to pass through; by setting several through holes in a uniform distribution, the stability of the through hole distribution is improved; by setting the through holes as round holes or polygonal holes, it is convenient to process.

[0034] Example 5

[0035] like Figures 1 to 2 As shown, a vertically installed photovoltaic device includes all the contents of Embodiment 4. In addition, the fixed traction cable includes a horizontal fixed traction cable 3 and an inclined fixed traction cable 4. The tops of adjacent pillars 5 are connected by the horizontal fixed traction cable 3, and the tops of the pillars 5 at the ends are fixed to the ground by the inclined fixed traction cable 4.

[0036] Optionally, the angle between the inclined fixed traction cable 4 and the ground is 45° or about 45°.

[0037] Optionally, the height of the vertically installed translucent plate 2 is determined by the crop being planted, and the height of the horizontally fixed traction cable 4 is determined by the height of the agricultural machinery.

[0038] The technical effects achieved by the above embodiments are as follows: the fixed traction cable connecting the vertical support of the photovoltaic module 1 reinforces the vertically installed photovoltaic module 1, thereby enhancing the wind resistance of the photovoltaic module 1; by using an angle of about 45° between the inclined fixed traction cable 4 and the ground, the inclined fixed traction cable 4 is kept in a relatively reasonable stress state.
