Description

Technical Field

[0001] This utility model relates to the field of photovoltaic power generation technology, and in particular to a photovoltaic power generation reflection device. Background Technology

[0002] Photovoltaic reflectors are designed to improve the light utilization rate of photovoltaic power generation equipment. They can reflect sunlight and focus it onto photovoltaic cells or light receiving panels, thereby increasing the light intensity on the photovoltaic cells and improving photoelectric conversion efficiency. With the continuous advancement of photovoltaic technology and the reduction of costs, photovoltaic reflectors will be more widely used. In the future, reflectors may develop towards greater efficiency, intelligence, and portability to adapt to different scenarios and needs.

[0003] Current reflective devices, during installation and use by users, still have the following shortcomings:

[0004] (1) Most of the existing reflectors on the reflector are fixed and cannot be adjusted. As the angle of sunlight changes, the reflector cannot reflect sunlight onto the photovoltaic panel well, resulting in poor reflection effect and thus affecting the photoelectric conversion efficiency.

[0005] (2) Most existing reflective devices do not have lifting devices. The reflector is at a fixed height. Changes in the illumination angle may cause the reflector to be blocked, which in turn affects the normal operation of the reflector and reduces the photoelectric conversion efficiency.

Next, the third motor 52 is started, which drives the threaded rod 53 to rotate. The threaded rod 53 drives the moving slide 54 to move along the guide rod 55, thereby changing the position of the reflector 31, which helps to... The reflection of light is followed by the activation of the fifth motor 563, which drives the lead screw 564 to rotate. The lead screw 564 drives the lifting column 41 to move upward along the square groove 561. The lifting column 41 raises the position of the reflector 31, preventing the reflector from being blocked by changes in the light angle, thus ensuring the normal operation of the reflector and improving the photoelectric conversion efficiency. Finally, the activation of the second motor 462 drives the fourth spur gear 463 to rotate. The fourth spur gear 463 drives the fifth spur gear 465 to rotate the steering shaft 45. The steering shaft 45 rotates in the circular hole 42, and through the steering seat 44, it drives the reflector 31 to rotate horizontally. This allows for further adjustment of the orientation of the reflector 31, resulting in better light reflection and improved reflection efficiency, which is beneficial for photoelectric conversion.
