Description

Technical Field

[0001] The utility model relates to the field of photovoltaic equipment, in particular to a light condensing device for photovoltaic modules. Background Art

[0002] Photovoltaic power generation is a technology that directly converts light energy into electrical energy by using the photovoltaic effect at the semiconductor interface. It mainly consists of three major parts: solar panel modules, a controller, and an inverter. The main components are composed of electronic components. Solar cells can be encapsulated and protected after being connected in series to form large-area solar cell modules, and then combined with components such as a power controller to form a photovoltaic power generation device.

[0003] For example, in a Chinese patent: the application number is 2024200151087, and the patent name is a light condensing device for photovoltaic modules, "including a base, two support frames are relatively arranged at the top of the base, a rotating shaft is rotatably connected between the two support frames, a reflector is arranged at the top of the rotating shaft, columns are arranged at both ends of the rotating shaft, and a photovoltaic panel is arranged between the two columns". In the above technology, a reflector is arranged below the photovoltaic panel to concentrate the light on the bottom of the photovoltaic panel, so that more solar energy can be obtained. However, the angle of the sun changes every minute, and the angle at which the reflector can reflect light and the distance between the reflector and the photovoltaic panel are fixed in the above technology. Thus, when the sun changes with time, the solar energy that the reflector can reflect will change. For example, the sunlight is the best at noon, but if the solar energy concentrated by the reflector is too concentrated, the solar panel may be burned due to too high temperature, or the sunlight is insufficient in the evening, and the reflector cannot concentrate the sunlight together, so the solar energy that the photovoltaic panel can generate will decrease.

[0044] During use: When it is necessary to adjust the refraction area of the reflector 7, for example, at noon, in order to prevent the sunlight from being too strong, when the reflector 7 refracts sunlight onto the photovoltaic panel 4, the sunlight is too concentrated and the temperature is too high, which may cause the photovoltaic panel 4 to be burned. Therefore, the first driving motor 62 can be started to rotate the first threaded rod 61, so that the first nut 27 moves. Through the link structure, the reflector 7 swings outwards, increasing the refraction angle of the photovoltaic panel 4, so that the area of sunlight refracted onto the photovoltaic panel 4 becomes larger. In this way, the sunlight is dispersed and the temperature on the photovoltaic panel 4 will decrease, preventing the photovoltaic panel 4 from being burned due to excessive temperature. When the first driving motor 62 rotates, it will drive the second nut 41 to rotate through the belt, causing the arc-shaped frame 11 to drive the second circular photovoltaic panel 8 to move, thereby adjusting the distance between the second circular photovoltaic panel 8 and the reflector 7, further increasing the area of sunlight refracted onto the photovoltaic panel 4, which can further protect the photovoltaic panel 4 from being burned. When it is evening and the sunlight is insufficient, the first driving motor 62 can be reversed, so that the area of sunlight refracted onto the photovoltaic panel 4 becomes smaller, so that the photovoltaic panel 4 can obtain more solar energy.
