[0031] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. 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.

[0032] Example 1:

[0033] like Figures 1 to 6 As shown, a photovoltaic sound barrier that increases light utilization includes: a base 1, H-shaped steel columns 11 and sound-absorbing panels 12. The H-shaped steel columns 11 are located on both sides of the base 1, and the sound-absorbing panels 12 are located between the H-shaped steel columns 11.

[0034] A photovoltaic module 2 is installed on the upper part of the interior of the H-shaped steel column 11, and a reflective device 3 is installed on the photovoltaic module 2. The reflective device 3 includes a reflector 31 and an electric push rod 32. The electric push rod 32 is mounted on the H-shaped steel column 11. The reflector 31 is hinged to the upper or lower or left and right sides of the photovoltaic module 2. The push rod of the electric push rod 32 is hinged to the end of the reflector 31 away from the photovoltaic module 2 to adjust the angle of the reflector 31. In this embodiment, the reflector 31 is coated with a white high-reflectivity coating 311. The white high-reflectivity coating 311 can be specular or diffuse reflective, thereby improving the reflectivity of the reflector 31.

[0035] In this embodiment, the reflector 3 is disposed on one or both sides of the photovoltaic module 2.

[0036] In this embodiment, a plurality of embedded parts 13 are provided on the base 1, and the embedded parts 13 are connected to the H-shaped steel columns 11. The H-shaped steel columns 11 and the embedded parts 13 are connected by nuts, and the embedded parts 13 are installed on the base 1 at equal intervals. This increases the connection stability between the H-shaped steel columns 11 and the base 1.

[0037] In this embodiment, multiple H-shaped steel columns 11 are provided. A column top cover 4 is installed on the top of the H-shaped steel column 11. A baffle 41 is installed on the column top cover 4. The baffle 41 can block the rain and snow above and protect the photovoltaic module 2.

[0038] In this embodiment, the sound-absorbing panel 12 is a metal sound-absorbing panel 12 or a non-metallic sound-absorbing panel 12 made of cement perforated board, cement wood chip board, or perlite board.

[0039] In this embodiment, the photovoltaic module 2 is a bifacial photovoltaic panel.

[0040] In summary: by adjusting the angle of the reflector 31 through the extension and retraction of the electric push rod 32 of the reflector device 3, the light utilization of the photovoltaic module 2 can be increased while avoiding shadow blocking and rain and snow accumulation. In addition, it can also play a role in noise reduction.

[0041] Example 2: As Figures 1 to 6 As shown, a photovoltaic sound barrier that increases light utilization differs from Embodiment 1 in that a reflective device 3 is provided on the bottom edge of the photovoltaic module 2.

[0042] On sunny days, by extending and retracting the electric push rod 32, the angle of the bottom reflector 31 can be adjusted so that the bottom reflector 31 is perpendicular to the H-shaped steel column 11, which can reflect the incident light onto the surface of the photovoltaic module 2, increase light utilization and thus increase the power generation of the photovoltaic module 2.

[0043] In rainy or snowy weather, the angle of the bottom reflective structure can be adjusted by extending and retracting the electric push rod 32, causing the bottom reflective structure to retract toward the H-shaped steel column 11, thereby preventing rain and snow from accumulating.

[0044] Example 3: As Figures 1 to 6 As shown, a photovoltaic sound barrier that increases light utilization differs from Embodiment 1 in that a reflective device 3 is provided on the top of the photovoltaic module 2.

[0045] By extending and retracting the electric push rod 32, the angle of the top edge plate is adjusted so that when the top edge plate reflects the incident light onto the surface of the photovoltaic module 2, it does not block the photovoltaic module 2 (avoiding the shadow shading of the photovoltaic module 2 surface when the sun's altitude angle is high at noon); at the same time, when the noise passes through the reflector 31, the sound is diffracted, further increasing the noise reduction effect.

[0046] Example 4: Figures 1 to 6As shown, a photovoltaic sound barrier for increasing light utilization, different from the embodiment 1 is that the light reflecting device 3 is arranged on both sides of the photovoltaic assembly 2.

[0047] By the extension and retraction of the electric push rod 32, the angle of the light reflecting structure on both sides is adjusted, so that the light reflecting structure on both sides will not block the photovoltaic assembly 2 when reflecting the incident light to the surface of the photovoltaic assembly 2.

[0048] When the photovoltaic assembly 2 is oriented in the north-south direction, the light reflecting device 3 is arranged on the south-facing side only, and the light reflecting device 3 is arranged on both sides in the remaining orientations.
