Description

Technical Field

[0001] The present invention relates to the technical field of support devices, and particularly to a support device for a photovoltaic power generation panel. Background Art

[0002] As a clean and renewable energy source, solar energy occupies an important position among various renewable energy sources. As an effective way to convert solar radiant energy into electrical energy, photovoltaic power generation technology has developed rapidly in recent years, promoting the booming rise of the photovoltaic industry.

[0003] The patent with the publication number CN221227400U relates to a support device for a photovoltaic power generation panel, including a photovoltaic power generation panel. A support plate is installed on the back of the photovoltaic power generation panel. An adjustable-angle support column is installed at the middle position of the side of the support plate facing away from the photovoltaic power generation panel. A pointed head for inserting into the ground is installed at the end of the support column away from the support plate. A cross plate is provided on the side of the support plate facing away from the photovoltaic power generation panel. A through hole is opened at the middle position of one side of the cross plate. The support column passes through the through hole. Positioning rings are provided on both the upper side and the lower side of the through hole. A knocking plate is provided on the side of the photovoltaic power generation panel facing away from the support plate. Two insertion columns are fixedly connected to the side of the knocking plate facing the photovoltaic power generation panel. Two jacks matching the insertion columns are symmetrically opened on the upper surface of the cross plate. The device has the following beneficial effects: The pointed head can be inserted into the ground by knocking without separating the photovoltaic power generation panel and the support column. However, during the process of fixing the solar panel, it is very difficult to adjust the angle of the solar panel. Therefore, when the angle between the sunlight and the solar panel is not aligned, the efficiency of the solar panel converting electrical energy will be reduced. Therefore, a support device for a photovoltaic power generation panel is proposed to solve the above-mentioned problems. Summary of the Invention

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

The output end of the motor 3 is fixedly connected to a pulley group 4. A rotating shaft 5 is fixedly connected to the axis of the upper pulley of the pulley group 4. A V-shaped plate 6 is fixedly connected to the circumferential surface of the rotating shaft 5. A fixing frame 7 is fixedly connected to the inner wall of the V-shaped plate 6. When installing the solar panel, place the support frame 1 on the ground. At this time, by knocking the pointed pile 2, it is fixed inside the ground, so that the support frame 1 can be firmly fixed. When the angle of the sunlight changes, the motor 3 is started to drive the pulley group 4 to rotate. The pulley group 4 rotates to drive the rotating shaft 5 to rotate through the belt. The rotating shaft 5 rotates to drive the V-shaped plate 6 to rotate. The V-shaped plate 6 rotates to drive the fixing frame 7 to rotate. The fixing frame 7 rotates to drive the photovoltaic panel 8 to rotate, so that the photovoltaic panel 8 can always maintain an angle perpendicular or close to perpendicular to the sunlight, enabling the photovoltaic panel 8 to receive more solar radiation energy, thereby improving the photoelectric conversion efficiency and increasing the power generation. A photovoltaic panel 8 is installed on the top of the V-shaped plate 6. A first fixing plate 9 is fixedly connected to the left side of the support frame 1.

The inner wall of the support frame 1 is rotatably connected to the circumferential surface of the rotating shaft 5. The bottom of the photovoltaic panel 8 is in contact with the top of the rubber block 11. At the same time, during the rotation of the photovoltaic panel 8, the photovoltaic panel 8 will come into contact with the rubber block 11 and generate a certain impact force, causing the rubber block 11 to move. The movement of the rubber block 11 drives the sliding rod 10 to move. The movement of the sliding rod 10 drives the spring to compress, thereby offsetting the impact force generated during the rotation of the photovoltaic panel 8 and preventing the photovoltaic panel 8 from being damaged due to excessive impact force caused by the photovoltaic panel 8 adjusting too fast due to strong wind.

[0016] Working principle: When installing the solar panel, place the support frame 1 on the ground. At this time, by knocking the pointed pile 2, it is fixed inside the ground, so that the support frame 1 can be firmly fixed. When the angle of sunlight changes, the motor 3 starts to drive the pulley group 4 to rotate. The rotation of the pulley group 4 drives the rotating shaft 5 to rotate through the belt. The rotation of the rotating shaft 5 drives the V-shaped plate 6 to rotate. The rotation of the V-shaped plate 6 drives the fixing frame 7 to rotate. The rotation of the fixing frame 7 drives the photovoltaic panel 8 to rotate, so that the photovoltaic panel 8 can always maintain an angle perpendicular or close to perpendicular to the sunlight, enabling the photovoltaic panel 8 to receive more solar radiation energy, thereby improving the photoelectric conversion efficiency and increasing the power generation. At the same time, during the rotation of the photovoltaic panel 8, the photovoltaic panel 8 will come into contact with the rubber block 11 and generate a certain impact force, causing the rubber block 11 to move. The movement of the rubber block 11 drives the sliding rod 10 to move. The movement of the sliding rod 10 will drive the spring to compress, thereby offsetting the impact force generated during the rotation of the photovoltaic panel 8 and preventing the photovoltaic panel 8 from being damaged due to excessive impact force caused by too fast adjustment speed of the photovoltaic panel 8 due to strong wind.

The movement of the connecting block 125 drives the snow removal plate 127 to move. The movement of the snow removal plate 127 drives the push rod 128 to move, so that the snow accumulated on the surface can be cleared during snowfall, preventing the snow from blocking the sunlight and causing the photovoltaic panel 8 to be unable to fully receive solar radiation, resulting in a reduction in power generation efficiency. At the same time, when installing the photovoltaic panel 8, the L-shaped pressing block 1210 will move downward through the elastic force of the spring, generating a squeezing force on the edge of the photovoltaic panel 8, thereby fixing the photovoltaic panel 8 to a certain extent, facilitating the installation of the photovoltaic panel 8 by workers and improving the convenience of installing the photovoltaic panel 8.

The movement of the inclined block 138 drives the moving rod 137 to move, so as to limit the rotation distance of the rotating shaft 5 to a certain extent, so that the photovoltaic panel 8 can stop at the required position, avoiding excessive rotation angle of the photovoltaic panel 8, resulting in an offset of the refraction angle with sunlight, and thus affecting the power generation efficiency.
