Existing photovoltaic brackets include fixed and movable types. The fixed type means that the photovoltaic panel cannot be moved after installation.

One end of the main connecting pipe is connected to the base, and the other end is connected to the mounting plate through the inclination adjustment mechanism.

DETAILED DESCRIPTION

[0018] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings. It is hereby stated that the directional terms such as up, down, left, right, front, back, inside, outside, etc. that appear or will appear in the text of the present invention are only based on the accompanying drawings of the present invention, and are not specific limitations of the present invention.

[0019] like Figure 1-Figure 7 As shown, a specific embodiment of the present invention provides an aluminum alloy photovoltaic bracket, including a tilt adjustment seat 100 and a guard frame 200, wherein the guard frame 200 is fixedly arranged on an attachment, and includes a main frame body 1, the left and right edges of the main frame body 1 are bent upward to form side guard plates 11, and movable guard covers 2 are hinged at the front and rear ends, and a lifting limit plate 16 is arranged in the center, and the movable guard cover 2 has a first plate surface 21 and a second plate surface 22 that are vertically connected to each other; the second plate surface 22 is hinged to a transmission rod 23; the transmission rod 23 includes a first rod body 231 and a second rod body 231 that is at a predetermined angle to the first rod body 231. Two rod bodies 232, a slider 24 is provided at the connection between the first rod body 231 and the second rod body 232; the lifting limit plate 16 is provided with a slide groove 161, and the slider 24 is arranged in the slide groove 161; a pressure rod 25 is provided at the end of the second rod body 232, and when not affected by external force, the top surface of the pressure rod 25 is higher than the upper surface of the main frame body 1; when the pressure rod 25 is pressed, it can drive the movable shield 2 to flip upward, the first plate surface 21 covers the front and rear edges of the main frame body 1, and the second plate surface 22 covers the gap between the first plate surface 21 and the main frame body 1; The inclination adjustment seat 100 includes a mounting plate 3, an inclination adjustment mechanism 4, a main connecting pipe 5 and a base 6. The mounting plate 3 is used to install photovoltaic panels. One end of the main connecting pipe 5 is connected to the base 6, and the other end is connected to the mounting plate 3 through the inclination adjustment mechanism 4. The inclination adjustment mechanism 4 is used to dynamically adjust the inclination of the mounting plate 3.

[0020] The pressure rod 25 is hinged to the second rod body 232 and can move vertically; when not affected by external force, the first rod body 231 is in a horizontal state, the second rod body 232 is tilted upward, and the slide groove 161 is arranged horizontally.

[0021] By adopting the above scheme, the photovoltaic bracket is divided into two parts: a movable tilt adjustment seat 100 and a fixed guard frame 200. In daily use, the photovoltaic panel is driven by the tilt adjustment seat 100, leaves the guard frame 200 and adjusts the tilt angle. For the measurement of wind speed, an anemometer can be installed near the bracket. When the wind speed exceeds a predetermined value, a protective action is triggered for a certain period of time. When encountering strong winds, the photovoltaic panel is placed in the guard frame 200, and the edges are protected by the side guard plates 11 and the movable shield 2, which is safe and reliable. Thanks to the above-mentioned separate design, the lightweight photovoltaic panel can be directly connected through the lighter mounting plate 3, and then connected and transmitted through a single main connecting pipe 5. The movable part is light and flexible, can be driven with lower power, and has small inertia, less wear on moving parts such as bearings, and a long service life.

[0022] The opening and closing of the movable shield 2 is controlled by mechanical linkage, and the movable shield 2 is connected to the side of the main frame 1 through the hinge shaft 26. Since the movable shield 2 has a tendency to automatically turn outward under the action of gravity, when the photovoltaic panel begins to leave the protective frame 200, the pressure of the mounting plate 3 on the pressure rod 25 disappears, and the movable shield 2 drives the pressure rod 25 to move upward through the transmission rod 23. The movable shield 2 automatically turns outward under the action of gravity, and the photovoltaic panel will not contact the movable shield 2 throughout the whole process. When the photovoltaic panel is retracted, the mounting plate 3 abuts against the pressure rod 25, and the pressure rod 25 is gradually pressed down. The first rod body 231 and the second rod body 232 of the transmission rod 23 push the second plate surface 22 of the movable shield 2 upward under the drive of the pressure rod 25, so that the movable shield 2 turns up, wraps the front and rear surfaces of the photovoltaic panel, and cooperates with the side guard plate 11 to form a windproof area around the four sides and part of the upper and lower surfaces of the photovoltaic panel, ensuring that the photovoltaic panel is not damaged by strong winds. If the mounting plate 3 remains stationary, the mounting plate 3 can lock the movable shield 2 through the pressure rod 25 and the transmission rod 23, and the movable shield 2 will not be blown open by strong wind.

[0023] The above design links the movement of the photovoltaic panel with the flipping action of the movable shield 2, which simplifies the electronic equipment originally used to independently control the movable shield 2, can reduce equipment costs, and avoid malfunctions of driving and sensing equipment in a long-term high-temperature exposure environment.

[0024] Preferably, the main frame 1 includes a photovoltaic guard plate 12 and a mounting plate stopper 13, and a hollow portion 14 is provided in the center of the photovoltaic guard plate 12; the mounting plate stopper 13 is fixedly arranged in the hollow portion 14, and the upper surface of the mounting plate stopper 13 is lower than the upper surface of the photovoltaic guard plate 12. By setting the upper surface of the mounting plate stopper 13 to be lower than the upper surface of the photovoltaic guard plate 12, and in combination with the thickness selection of the mounting plate 3, when the mounting plate 3 abuts against the mounting plate stopper 13, the photovoltaic panel and the photovoltaic guard plate 12 can maintain a reasonable gap, so that there will be no contact and collision, and because the distance is not too far, excessive wind pressure will not be formed between the photovoltaic panel and the photovoltaic guard plate 12 in strong winds, thereby playing a role in better protecting the photovoltaic panel.

[0025] Combination Figure 5 and Figure 6 As shown, the inclination adjustment mechanism 4 includes an inclination connecting shaft 41, a transmission shaft 42, an inclination seat 43, a first helical gear 44, a second helical gear 45 and an inclination motor 46; the inclination seat 43 is fixedly arranged at the top end of the main connecting pipe 5, and the inclination seat 43 is provided with a connecting hole 431, and the inclination connecting shaft 41 is arranged in the connecting hole 431; the inclination connecting shaft 41 is fixedly connected to the mounting plate 3; the transmission shaft 42 is sleeved in the main connecting pipe 5, the upper end is connected to the second helical gear 45, and the lower end is connected to the inclination motor 46; the inclination connecting shaft 41 is also provided with the first helical gear 44, and the first helical gear 44 is meshed with the second helical gear 45.

[0026] Combination Figure 7 As shown, the base 6 includes a first articulated seat 61, a second articulated seat 62 and an electric push rod 63. The first articulated seat 61 is hinged to the lower end of the main connecting tube 5. The second articulated seat 62 is provided with an electric push rod 63. The rod body of the electric push rod 63 is connected to the main connecting tube 5.

[0027] It should be noted that the tilt adjustment seat 100 is used to adjust the tilt angle of the mounting plate 3, that is, the photovoltaic panel, and cooperates with the corresponding controller to reduce the tilt angle between the panel surface and the sunlight. The specific adjustment method is: first, the main connecting pipe 5 is pushed to swing around the first hinge seat 61 by the extension and contraction of the electric push rod 63, so that the photovoltaic panel can leave or return to the protective frame 200. When the photovoltaic panel leaves the protective frame 200 for a certain distance, the tilt motor 46 rotates, and drives the transmission shaft 42 to rotate through the first gear 47 and the second gear 48 that mesh with each other in turn. The transmission shaft 42 drives the tilt connection shaft 41 to swing relative to the tilt seat 43 through the second helical gear 45 and the first helical gear 44. Since the tilt connection shaft 41 is fixedly connected to the mounting plate 3, and the tilt seat 43 is fixedly connected to the main connecting pipe 5, the mounting plate 3 will swing downward relative to the main connecting pipe 5, thereby controlling the tilt angle of the photovoltaic panel. The bottom of the mounting plate 3 has an avoidance connection portion 31 extending downward, and the inclination connection shaft 41 is connected to the mounting plate 3 through the avoidance connection portion 31, so that there is a certain distance between the bottom surface of the mounting plate 3 and the inclination seat 43, so as to avoid interference between the mounting plate 3 and the inclination seat 43 when swinging. The above structure directly sets the heavier inclination motor 46 on the first hinge seat 61, so that the linear speed of the swinging process is small, and the total mass of the upper end structure of the main connecting tube 5 is controlled to ensure that the photovoltaic panel swings more flexibly and smoothly. This embodiment protects the photovoltaic panel by a fixedly set guard frame, and cooperates with the inclination adjustment mechanism 4 located at the bottom of the mounting plate 3. There is no need to set an additional drive structure on the side of the mounting plate 3, which can maximize the area of ​​the photovoltaic panel and improve the photoelectric conversion power. The extension and retraction of the electric push rod 63 pushes the main connecting tube 5 to swing around the first hinge seat 61, and then drives the mounting plate 3 to rise and fall, providing space for the swing of the mounting plate 3; the mounting plate 3 can swing independently relative to the main connecting tube 5 under the drive of the inclination motor 46, without being restricted by the inclination of the main connecting tube 5, and flexibly adjusts the angle between the photovoltaic panel and the sunlight, thereby improving the utilization rate of light energy.

[0028] In order to be more flexibly installed in the target area, the tilt adjustment seat 100 further includes a first guide rail 7 and a second guide rail 8 arranged in parallel, the first hinge seat 61 is fixedly arranged at a predetermined position of the first guide rail 7 through a first mounting groove 611 at the bottom, and the second hinge seat 62 is fixedly arranged at a predetermined position of the second guide rail 8 through a second mounting groove 621 at the bottom. During installation, it is only necessary to arrange the first guide rail 7 and the second guide rail 8 first, fix the guard frame 200, and finally fix the first hinge seat 61 and the second hinge seat 62 at the predetermined positions of the first guide rail 7 and the second guide rail 8 through the corresponding first mounting groove 611 and the second mounting groove 621 and bolts, and the entire system can be installed, which is easy to install and has strong adaptability.

[0029] Preferably, the outer contour of the photovoltaic guard plate 12 matches the outer contour of the photovoltaic panel; the mounting plate limit plate 13 is a U-shaped structure, including a pair of mutually parallel limit side plates 131. The U-shaped mounting plate limit plate 13 reserves movable space for components such as the tilting seat 43 and the main connecting pipe 5, and the pair of mutually parallel limit side plates 131 can guide the mounting plate 3 when abutting against the mounting plate 3, so as to avoid collision between the photovoltaic panel and the photovoltaic guard plate 12 due to accidental tilting of the mounting plate 3.

[0030] Preferably, the guard frame 200 further comprises legs 15, and the photovoltaic guard plate 12 and the mounting plate limit plate 13 are supported above the attachment by the legs 15. The guard frame 200, the mounting plate 3 and the main connecting pipe 5 are all made of aluminum alloy.

[0031] It should be noted that the protective frame 200, mounting plate 3 and main connecting pipe 5 formed of aluminum alloy can further reduce the weight of the swing device. In addition, aluminum alloy has high strength and mature production technology, which can control material costs while reducing the possibility of distortion and damage of the swing device due to external forces.

[0032] The above is a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the principle of the present invention. These improvements and modifications are also considered to be within the scope of protection of the present invention.
