Description

Technical Field

[0001] The present application relates to the technical field of photovoltaic panel drainage, and in particular to a photovoltaic panel drainage device. Background Art

[0002] Photovoltaic panels, also known as solar panels, are devices that convert light energy into electrical energy. They are composed of multiple photovoltaic cells. When light shines on the cells, light energy is converted into electrical energy. The working principle of photovoltaic panels is mainly based on the photoelectric effect. Through light irradiation, photons interact with semiconductor materials, causing electrons and holes to separate and move in the PN junction to form a photocurrent. This photocurrent is powered or stored through an external circuit, thereby realizing the utilization and conversion of solar energy.

[0003] However, in actual applications, when existing photovoltaic panels are in use, the accumulated water formed on them after rainfall will cause a series of problems. First, the accumulated water will cover the surface of the photovoltaic panels, resulting in the inability of sunlight to directly shine on the panels, thereby reducing the panels' absorption and conversion efficiency of light energy. The accumulated water will interfere with the light, causing refraction and scattering of light, further reducing the effective light energy reaching the panels, which not only affects the power generation efficiency of the photovoltaic panels, but also limits their performance on cloudy days or under insufficient light conditions. Therefore, a device for draining water from photovoltaic panels is needed.

[0004] Therefore, those skilled in the art provide a photovoltaic panel drainage device to solve the problems raised in the above background technology. Utility Model Content

[0012] In summary, this application includes the following beneficial technical effects:

[0013] 1. The motor can drive multiple drainage components to operate through the transmission connecting rod to drain a row of multiple photovoltaic panels. The first drainage pipe is driven to closely contact the upper end of the photovoltaic panel through the rotating shaft and the first shell in conjunction with the torsion spring. The transmission connecting rod drives the connecting sleeve and the fan blade to rotate, forming suction in the second shell, and the accumulated water on the photovoltaic panel is extracted and discharged through the first drainage pipe, the second drainage pipe and the second shell.
