Description

Technical Field

[0001] The present invention relates to the field of photovoltaic technology, and in particular to a three-dimensional light tracking photovoltaic support system. Background Art

[0002] As the global demand for renewable energy continues to grow, the development and utilization of solar energy as a clean and renewable energy form has received widespread attention. As one of the main ways to utilize solar energy, the efficiency and stability of photovoltaic power generation are directly related to the effective conversion and utilization of solar energy resources. However, most traditional photovoltaic support systems use fixed installations and cannot automatically adjust the angle of photovoltaic modules according to the position of the sun, resulting in low light utilization efficiency, especially in areas or seasons where the light angle changes greatly. This problem is particularly prominent.

[0003] In addition, severe weather conditions, such as strong winds and heavy rains, also pose severe challenges to the stability and safety of photovoltaic support systems. Fixed photovoltaic support systems are often easily damaged when facing extreme weather, which not only affects the power generation efficiency of photovoltaic modules, but also may cause economic losses and safety hazards.

[0004] In order to overcome these shortcomings of traditional photovoltaic support systems and improve the solar energy collection efficiency and system stability and safety, the market urgently needs a three-dimensional light tracking photovoltaic support system that can intelligently track light, automatically adjust the angle of photovoltaic modules, and maintain stable operation under severe weather conditions. Summary of the invention

[0005] In view of the problems existing in the above-mentioned background technology, the present invention patent aims to propose an innovative solution, namely a three-dimensional light tracking photovoltaic support system.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: A three-dimensional light tracking photovoltaic bracket system, including a fixed bracket, a first motor and a second motor, the first motor is fixedly connected to the front surface of the fixed bracket, the driving end of the first motor is fixedly connected to a driving rod, the end of the driving rod away from the first motor is rotatably connected to the first movable rod through a rotating shaft, the end of the first movable rod away from the driving rod is rotatably connected to a movable plate through a rotating shaft, the upper surface of the movable plate is symmetrically fixedly connected to two fixed rods, the end of the fixed rod away from the movable plate is fixedly connected to a mounting bracket, the front surface of the movable plate away from the end of the first movable rod is rotatably connected to the second movable rod through a rotating shaft, the top of the fixed bracket is provided with a slot, the slot is located between the first movable rod and the second movable rod, the second motor is fixedly connected to the inner bottom wall of the slot, the driving end of the second motor is fixedly connected to a screw rod, the outer surface of the screw rod is threadedly connected to a connecting plate, the front surface of the top of the connecting plate is rotatably connected to a limiting rod through a rotating shaft, and the end of the limiting rod away from the connecting plate is rotatably connected to the front surface of the movable plate through a rotating shaft.

[0007] Preferably, the movable plate and the mounting bracket are both inclined, and the inclination slopes of the movable plate and the mounting bracket are the same, so that when the first motor drives the first movable rod to change the inclination angle of the movable plate, the mounting bracket on the movable plate also changes the angle of the mounting bracket as the movable plate moves, which facilitates tracking of light by adjusting the photovoltaic components installed on the mounting bracket.

[0008] Preferably, a limiting groove is provided on the top of the fixed bracket, and the limiting groove is located on the side of the groove away from the first movable rod. The bottom end of the second movable rod is movably connected to the inside of the limiting groove. The second movable rod can be limited by the limiting groove, so that the movable plate is limited by the second movable rod, so that the first motor drives the movable plate to adjust the angle according to a fixed trajectory.

[0009] Preferably, the bottom end of the connecting plate is movably clamped inside the slot, and the connecting plate can be limited by the slot, so that the second motor drives the screw rod to drive the connecting plate to move up and down along the slot in a straight line, thereby further adjusting the angle of the mounting bracket on the movable plate.

[0010] Preferably, a plurality of threaded holes are provided on the top of the mounting bracket, and photovoltaic modules can be installed through the threaded holes on the mounting bracket.

[0011] Working principle: When in use, first, the entire system is mounted on the roof through the fixing bracket to ensure stability and reliability. The PV module is fixed to the bracket using the threaded holes on the mounting bracket for easy tracking and adjustment. The first motor drives the drive rod, which in turn drives the first movable rod to rotate. This movement is transmitted to the movable plate through the transmission chain, allowing it to move along a specific trajectory, thereby changing its angle. The connecting plate limits the movable plate through the limit rod to ensure its stability and accuracy during movement. The second movable rod clamps the movable plate in the limit slot, providing further limit to prevent the movable plate from deviating from the predetermined trajectory during movement. The second motor drives the screw rod to enable the connecting plate to move up and down along the limit slot. This design allows the position of the movable plate to be fine-tuned, thereby changing the tilt angle of the PV module on the mounting bracket to adapt to different lighting conditions. In extremely severe weather conditions, the position of the movable plate can be quickly adjusted to keep it horizontal through the synergy of the first and second motors. This design helps to reduce wind resistance and reduce the potential damage to PV modules caused by strong winds. At the same time, the distance between the movable panels and the fixed brackets is increased, providing more circulation space for the wind, thereby slowing down the wind speed. This helps protect the photovoltaic modules from the influence of severe weather such as strong winds, ensuring the safety and stability of the system.

[0012] The present invention provides a three-dimensional light tracking photovoltaic support system. It has the following beneficial effects: 1. The three-dimensional light tracking photovoltaic support system, driven by the first motor, can move the movable plate along a specific track, thereby changing the angle of the photovoltaic module and achieving accurate tracking of the light. This dynamic adjustment ensures that the photovoltaic module always faces the best light direction, improves the efficiency of solar energy collection, and thus increases power generation.

[0013] 2. The three-dimensional light tracking photovoltaic support system not only supports angle adjustment, but also achieves fine adjustment of the position of the movable plate through the drive of the second motor and the design of the screw. This dual adjustment mechanism enables the photovoltaic components to be finely adjusted according to the changes in light at different times, seasons and weather conditions to achieve the best power generation effect.

[0014] 3. The combination of the connecting plate and the limit rod of the three-dimensional light tracking photovoltaic bracket system ensures the stability and accuracy of the movable plate during movement and prevents deviation from the predetermined trajectory. The clamping design of the second movable rod in the limit groove further improves the stability of the system. In extremely bad weather, by quickly adjusting the movable plate to a horizontal state and increasing the distance between the movable plate and the fixed bracket, the impact of wind resistance and wind speed on the photovoltaic module is effectively reduced, protecting the safety of the system.

[0015] 4. This three-dimensional light tracking photovoltaic support system is not only suitable for various roof installation environments, but also can maintain efficient operation under different lighting and weather conditions. Its flexible adjustment mechanism and stable structural design enable the system to cope with various complex and changing environmental conditions, improving overall adaptability and reliability.
