Description

Technical Field

[0001] The invention belongs to the field of photovoltaic power generation, and in particular relates to a mounting bracket for a photovoltaic power generation panel and a photovoltaic power generation system. Background Art

[0002] As the global energy crisis and environmental pollution become increasingly serious, the development of renewable energy has received more and more attention. Photovoltaic power generation, as a type of renewable energy, has broad development prospects. In the future, photovoltaic power generation will develop in a more efficient, economical and environmentally friendly direction. At the same time, with the advancement of technology and large-scale application, the cost of photovoltaic power generation will be further reduced, becoming a more competitive energy supply method. The basic principle of photovoltaic power generation is the photovoltaic effect, which is the phenomenon that when light causes an uneven semiconductor or solid to produce a potential difference. In photovoltaic power generation, the photovoltaic panel is the core part, which can convert the sun's radiation into electrical energy, or send it to the battery for storage, or drive the load to work.

[0003] Due to the rotation of the earth and the apparent motion of the sun, the position of the sun and the direction of its light are constantly changing. Therefore, for a photovoltaic power generation system in a fixed location, if it can be effectively ensured that the photovoltaic panels are always facing the sun, the efficiency of the photovoltaic power generation system will reach the best state.

[0004] In the prior art, in order to cope with the changes in the position of the sun in the morning, noon and evening, an angle adjustment mechanism is provided on the bracket of the photovoltaic panel to adjust the tilt angle of the photovoltaic panel relative to the ground, thereby ensuring that the photovoltaic panel is always facing the sun. However, due to different seasons, the direct point of the sun is also different. For example, in spring and autumn, the direct point of the sun is roughly located near the equator; in summer, the direct point of the sun moves north to near the Tropic of Cancer; in winter, the direct point of the sun moves south to near the Tropic of Capricorn. Therefore, if only the tilt angle of the photovoltaic panel can be adjusted, it cannot be guaranteed that the photovoltaic panel is always facing the sun, resulting in the efficiency of the photovoltaic power generation system not reaching the optimal state.

Specifically, the first transmission member 23 can be an external gear, and the second transmission member 24 can be an internal gear; the second transmission member 24 can be installed on the mounting plate 29 by a fixing structure such as a screw, or a first through hole can be arranged at the center of the mounting plate 29, and the second transmission member 24 can be installed on the inner side wall of the first through hole, or directly formed integrally on the inner side wall of the through hole, which is not limited in this embodiment.

[0028] The first transmission member 23 may be coaxially arranged on the transmission shaft of the first driving member 22, or may be connected to the first driving member 22 through a transmission structure such as a belt 28.

A third through hole may be arranged at the center of the first limiting member 251, and the first rotating shaft 27 passes through the third through hole to connect with the first transmission member 23. The first limiting member 251 may be fixedly disposed on the bottom surface of the mounting plate 29, or may be integrally formed with the mounting plate 29 on the bottom surface of the mounting plate 29. There may be multiple second limiting members 252, specifically three, forming a triangular structure, so as to limit the first limiting member 251 on the adapter plate 21, so that the first limiting member 251 can only rotate relative to the adapter plate 21.

[0030] The limiting assembly 25 further includes a second rotating shaft, and the second limiting member 252 is rotatably connected to the mounting plate 29 via the second rotating shaft. Specifically, the second rotating shaft can be connected to the second limiting member 252 via a bearing, so that when the mounting plate 29 rotates, the first limiting member 251 and the second limiting member 252 can rotate relatively, thereby reducing the friction between the first limiting member 251 and the second limiting member 252, avoiding greater wear on the contact surface of the two, and increasing the service life of the mounting bracket.

Specifically, there can be two support columns 32 and two first rotating columns 33, respectively. The support columns 32 and the first rotating columns 33 are spaced apart on the mounting plate 29 and are respectively located at a corner of the photovoltaic panel to ensure the stability of the photovoltaic panel. The second driving member 31 can be an electric cylinder, and the movement of the electric cylinder drives the connecting column 35 to move linearly, thereby driving the connecting column 35 to change the angle formed between the first rotating column 33 and the second rotating column 34, so as to achieve the angle adjustment of the photovoltaic panel relative to the horizontal plane. In one embodiment, the length of the support column 32 is greater than the sum of the length of the first rotating column 33 and the length of the second rotating column 34, so that the photovoltaic panel can be adjusted at multiple angles, thereby further adapting to the angle of the sun in the morning, noon and evening.

[0032] The mounting bracket further includes a power storage box 4, which is disposed on the mounting plate 29 and is electrically connected to the angle adjustment module 3, the rotation drive module 2 and the photovoltaic power generation panel. Specifically, the power storage box 4 can store the electric energy of the photovoltaic power generation panel, and when the photovoltaic power generation panel needs to be angle adjusted or rotated, the electric energy of the power storage box 4 can be used to drive the photovoltaic power generation panel, avoiding the need for external power to achieve driving, reducing the steps of installing external power, and facilitating installation.

[0033] The base 1 is also provided with ground spikes 5 so that the mounting bracket can be stably mounted on the bottom surface after installation.

[0035] In summary, the present invention, on the one hand, uses an angle adjustment mechanism to adjust the inclination angle of the photovoltaic panel relative to the base 1 to ensure that the photovoltaic panel can always face the sun during the day, and on the other hand, uses a rotating drive module 2 to drive the photovoltaic panel to rotate relative to the base 1, thereby allowing the photovoltaic panel to adapt to the direct sunlight point in different seasons, ensuring that the efficiency of the photovoltaic power generation system can be maximized. Therefore, the present invention effectively overcomes the various shortcomings of the prior art and has a high industrial utilization value.
