Description

Technical Field

[0001] The utility model belongs to the technical field of photovoltaic component support structures, and in particular relates to an adjustable support beam for improving the efficiency of photovoltaic components. Background Art

[0002] Solar photovoltaic array products convert solar energy into electrical energy, which is then stored in batteries and then supplied to the system itself or input into the grid through an inverter. During installation, the photovoltaic array is required to have an optimal angle to ensure that the photovoltaic modules can achieve the maximum energy conversion efficiency.

[0003] At present, large-scale photovoltaic modules are mostly installed using fixed brackets. The bracket installation adopts the average optimal inclination angle throughout the year and cannot be adjusted. However, due to the influence of the earth's revolution and rotation, the angle of sunlight on the photovoltaic modules is different in each season and at each time. The fixed-structure photovoltaic module bracket cannot guarantee that the photovoltaic modules always maintain a high light reception rate. Even the existing adjustable brackets have a simple structure, and most of them can only adjust the inclination angle of the photovoltaic modules. They cannot fully achieve the maximum electrical energy conversion efficiency of the photovoltaic modules according to the sunlight angle in different seasons or at different times. Therefore, there is still a lot of room for improvement in the efficiency of light energy utilization. In addition, the existing photovoltaic module bracket structure is fixed, which is not convenient for construction personnel to store and use the bracket structure when installing and disassembling photovoltaic modules, affecting the installation and disassembly progress and reducing the installation efficiency.

[0026] The rotating frame 3 is arranged on the upper surface of the support seat 1 and a clamping limit mechanism that can limit the rotating frame 3 is arranged at the bottom of the rotating frame 3. The clamping limit mechanism includes a sliding card plate 9, a limit column 10 and an electromagnetic push rod 11. The number of sliding card plates 9 is four and the four sliding card plates 9 are fixedly connected to the four corners of the lower surface of the rotating frame 3 in the form of a rectangular array. Both sides of the bottom of the rotating frame 3 are fixedly connected with reinforcing plates 12 for enhancing firmness. The middle parts of the lower surfaces of the two reinforcing plates 12 are fixedly connected with limit columns 10 that can limit the rotation angle of the rotating frame 3. The middle parts of the upper surfaces of the two reinforcing plates 12 are fixedly installed with electromagnetic push rods 11 and the movable ends of the electromagnetic push rods 11 are inserted into the lower parts of the reinforcing plates 12.

After the rotating frame 3 is rotated to the corresponding position, the movable ends of the electromagnetic push rods 11 on both sides are pushed out and inserted into the corresponding positioning holes 15, which can play a role in limiting and fixing the rotating frame 3 and prevent the rotating frame 3 from being offset by external force;

[0027] A transverse driving structure is arranged inside the rotating frame 3, and the movable end of the transverse driving structure is rotatably connected with an angle adjustment plate 4. A mounting plate 2 is hingedly connected to one side of the upper surface of the rotating frame 3 through a hinge. An electronic level 26 capable of measuring the inclination angle is fixedly installed on one side of the back of the mounting plate 2. The electronic level 26 can detect the inclination angle of the mounting plate 2 at all times, so as to adjust the mounting plate 2 through the transverse driving structure according to the angle between the sun and the area where the photovoltaic components are installed, so that the mounting plate 2 is adjusted to an angle that can be directly exposed to sunlight; threaded holes for installing photovoltaic components are provided on the surface of the mounting plate 2, and through grooves for ensuring heat dissipation of the photovoltaic components and lightweight overall structure are also provided on the surface of the mounting plate 2;

[0028] The transverse driving structure includes a second motor 16, a threaded screw 17, a screw slider 18 and a transverse moving rod 19. The first motor 5, the electromagnetic push rod 11, the second motor 16 and the electronic level 26 are all electrically connected to the external control unit through wires and are all existing well-known technologies, so they will not be elaborated on here; the body of the second motor 16 is fixedly installed in the middle of the back of the rotating frame 3 and the output end is connected to the threaded screw 17 through a spline, the threaded screw 17 is rotatably connected to the middle of the rotating frame 3 and is externally connected to the screw slider 18, both sides of the screw slider 18 are fixedly connected to the transverse moving rod 19, both sides of the interior of the rotating frame 3 are fixedly connected to the limit rods 20 and the two transverse moving rods 19 are respectively connected to the outside of the two limit rods 20 in a transverse sliding manner, the angle adjustment plate 4 is rotatably connected to the outside of the transverse moving rod 19 and there are four of them, four angles The adjusting plate 4 is evenly divided into two groups and the two groups of angle adjusting plates 4 are rotatably connected to the outside of the two transverse moving rods 19 respectively.

The tops of the four angle adjusting plates 4 are rotatably connected to the four rotating pins 21 respectively. The second motor 16 drives the threaded screw 17 to rotate, which can drive the screw slider 18 to move laterally, thereby pushing the angle adjusting plate 4 to move through the transverse moving rods 19 on both sides. When the screw slider 18 drives the bottom end of the angle adjusting plate 4 to move toward the end away from the second motor 16, the inclination angle of the mounting plate 2 can be reduced; when the screw slider 18 drives the bottom end of the angle adjusting plate 4 to move toward the end close to the second motor 16, the inclination angle of the mounting plate 2 can be increased, so that the angle of the photovoltaic module can be adjusted according to the position of the sun;

[0029] The top end of the angle adjustment plate 4 is rotatably connected to the back side of the mounting plate 2, and the back of the rotating frame 3 corresponding to the four angle adjustment plates 4 are provided with a slot 22 for accommodating the angle adjustment plate 4, and the angle adjustment plate 4 can be rotatably accommodated in the slot 22 corresponding thereto, and a pop-up component that can lift one end of the mounting plate 2 is provided on the side of the rotating frame 3 away from the hinge of the mounting plate 2, and the pop-up component can abut against the back side of the mounting plate 2, and the pop-up component includes a fixed block 23, a spring 24 and a top plate 25, the bottom end of the spring 24 is fixedly connected to the upper surface of the fixed block 23 and the top end is fixedly connected to the top plate 25, the top plate 25 is higher than the top end of the rotating frame 3 and can abut against the back side of the mounting plate 2, and the fixed block 23 is fixedly connected to the back side of the rotating frame 3, and the number of pop-up components is eight, and two pop-up components are provided on both sides of each slot 22. When the device needs to be folded, the lateral moving structure is driven to The bottom of the angle adjustment plate 4 moves toward the end away from the second motor 16 until it approaches a horizontal state, and the angle adjustment plate 4 can be stored in the corresponding slot 22, and the mounting plate 2 will press the top plate 25 downward, and the spring 24 is in a tensioned state; when the mounting plate 2 needs to be lifted up again, the lateral moving structure is driven to move the bottom of the angle adjustment plate 4 toward the end close to the second motor 16. Since the angle adjustment plate 4 approaches a horizontal state but is not completely horizontal when the mounting plate 2 is retracted, the angle adjustment plate 4 may get stuck when the mounting plate 2 is propped up again. Therefore, a pop-up component is provided, and when the lateral moving structure drives the angle adjustment plate 4 to lift the mounting plate 2, the end of the mounting plate 2 in contact with the top plate 25 will be lifted up by the elastic force of the spring 24, thereby ensuring that the angle adjustment plate 4 is lifted up smoothly, thereby adjusting the mounting plate 2 to the desired angle, and ensuring the normal use of the device structure.

[0030] In summary, the adjustable support beam for improving the efficiency of photovoltaic modules is used in the following steps:

[0031] 1. Install the photovoltaic module on the mounting plate 2, adjust the lateral movement structure according to the change of seasons, and use the electronic level 26 to tilt the mounting plate 2 to an angle that can be directly exposed to the current sunlight;

[0032] 2. Then, according to the sunrise and sunset of the sun every day, the rotating mechanism is controlled to drive the rotating frame 3 and the photovoltaic components above it to rotate, so that the photovoltaic components can rotate with the position of the sun like a sunflower, ensuring that the photovoltaic components have the maximum power conversion efficiency;

[0033] 3. Each time the rotating frame 3 is rotated, the electromagnetic push rod 11 can fix the position of the rotating frame 3 to ensure the stability of the rotating frame 3 structure. At the end of the day, the rotating frame 3 is rotated back to the position where the photovoltaic components can be aligned with the sunrise, and the second and third steps are repeated;

[0034] 4. When the device needs to be stored, control the lateral moving structure to retract the mounting plate 2 to a horizontal state, and rotate the rotating frame 3 to the middle of the support seat 1 through the rotating mechanism, which is convenient for operation and saves manpower, and is more convenient for use when installing or storing photovoltaic modules.

[0035] The above description is only for illustrating the present invention, and it should be understood that the present invention is not limited to the above embodiments, and various variations that conform to the concept of the present invention are within the protection scope of the present invention.
