Description

Technical Field

[0001] The utility model relates to the field of photovoltaic power generation, and more specifically to a photovoltaic panel mounting frame with adjustable inclination. Background Art

[0002] As a clean and renewable energy source, solar energy is increasingly valued by countries around the world. With the strong support of governments around the world, the global solar photovoltaic industry has developed rapidly. However, the efficiency of photovoltaic power generation systems has always been a concern. The orientation of the panels in a photovoltaic system is one of the key issues in the design.

[0003] Photovoltaic panels mainly absorb sunlight and convert solar radiation energy directly or indirectly into electrical energy through the photoelectric effect or photochemical effect. In other words, the more solar radiation a photovoltaic panel receives, the more electrical energy it can convert. Therefore, the output power of solar panels depends on factors such as solar irradiance. Most photovoltaic panels in existing photovoltaic power generation devices are fixedly placed, and their orientation is set based on the principle of obtaining the most electrical energy within a certain period of time. However, as the sun moves every day, the intensity of the light beam changes continuously, and it cannot guarantee that sufficient sunlight continues to be incident vertically. Oblique irradiation can easily reduce the absorption of sunlight by photovoltaic panels, affecting the conversion of electrical energy. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the deficiencies in the prior art and provide a photovoltaic panel mounting frame with adjustable inclination angle.

[0005] The utility model discloses a photovoltaic panel mounting frame with adjustable inclination angle, which is realized by the following technical scheme, including: a rotating base, a mounting frame, a mounting frame, a supporting frame and a driving assembly;

[0006] The rotating base includes a base 11, a mounting plate 13 and a first motor 12. The first motor is mounted on the base, and the output shaft of the first motor faces upward. The output shaft is connected to the mounting plate to drive the mounting plate to rotate. Four support wheels 14 are installed on the bottom surface of the mounting plate. The four support wheels are arranged around the rotation center of the mounting plate. When the first motor drives the mounting plate to rotate, the support wheels roll on the base to support the mounting plate.

[0007] The mounting frame 20 is formed into an L shape by a horizontal frame and a vertical frame. The bottom edge of the vertical frame is fixed to one end of the mounting plate. The two ends of the horizontal frame are fixed to the two ends of two parallel adjustment plates 22. A plurality of equally spaced limiting grooves 23 are provided on the upper side of each adjustment plate. The cross section of the limiting groove is semicircular.

[0008] One short side of the mounting frame is hinged to the top side of the vertical frame, and the middle parts of the two long sides of the mounting frame are respectively hinged to the upper ends of the support frames. The mounting frame 21 is used to mount photovoltaic panels.

[0009] The bottom edge of the support frame 30 is a round rod 31, the diameter of which is less than or equal to the diameter of the limiting groove; the round rod at the lower end of the support frame is used to be clamped in the limiting groove to support the installation frame.

[0010] The driving assembly includes two push plates 41, a screw rod 42, a guide rod 43 and a second motor 44. The two push plates are arranged on both sides of the round rod. The push plates are provided with an inclined surface on the side facing the round rod. When the push plates push the round rod, the round rod is lifted upward through the inclined surface, so that the round rod is disengaged from the limiting groove. The two ends of the screw rod are rotatably connected with the middle part of the bottom edge of the two ends of the horizontal frame, and are threadedly connected with the two push plates. The threaded holes on the two push rods have the same thread rotation direction. The guide rod is arranged parallel to the screw rod, and the two ends of the guide rod are rotatably connected with the middle part of the bottom edge of the two ends of the horizontal frame. The two push rods are slidably matched with the guide rod. The second motor is installed on one side of the mounting frame, and the output end of the second motor is connected to the screw rod to drive the screw rod to rotate. The second motor drives the screw rod to rotate, and the screw rod drives the push plate to move. The push plate squeezes the round rod, and the round rod moves upward along the inclined surface of the push plate relative to the push plate until it is disengaged from the limiting groove. The push plate continues to push the round rod, and the round rod falls into the next limiting groove, changing the angle between the mounting frame and the horizontal plane.

[0011] Working principle: The first motor drives the mounting plate to rotate, so that the photovoltaic panel can rotate in the vertical direction; at the same time, the second motor drives the screw to rotate, thereby driving the push plate to move. The push plate pushes the round rod on the support frame into different limit grooves to adjust the angle between the photovoltaic panel and the horizontal plane, so that the photovoltaic panel is perpendicular to the sunlight.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The utility model can drive the screw to rotate through the second motor, thereby driving the push plate to move. The push plate pushes the round rod on the support frame into different limit grooves to adjust the angle between the photovoltaic panel and the horizontal plane. On this basis, the first motor drives the mounting plate to rotate, so that the photovoltaic panel can rotate in the vertical direction, so that the photovoltaic panel installed on the mounting frame can remain perpendicular to the sunlight, thereby ensuring the power generation efficiency.

[0014] 2. The limiting groove in the utility model is semicircular, and even if the angle between the support frame and the mounting frame is too large, it will not fall out of the limiting groove, and the structure is more stable. BRIEF DESCRIPTION OF THE DRAWINGS
