Problems solved by technology
[0007] Aiming at the above problems, the present invention provides a solar tracking photovoltaic power generation device. By using the suction force of the electromagnet, the water tank is first driven to spray water on the photovoltaic panel, and then the cleaning roller is driven to rotate to clean the surface of the photovoltaic panel, so that the cleaning of the cleaning roller is similar to that of the photovoltaic panel. The effective combination of water spraying steps solves the technical problem of automatic cleaning of the surface of photovoltaic panels, realizes the rapid cleaning of the surface of photovoltaic panels, and recycles the cleaned water to improve the utilization rate of water resources

Abstract
The invention provides a solar tracking photovoltaic power generation device which is aimed at solving a technical problem of automatic cleaning of a photovoltaic panel surface. The solar tracking photovoltaic power generation device includes a mounting seat, a photovoltaic panel, a tracking assembly and a cleaning assembly. The cleaning assembly includes a cleaning unit, a water adding unit and adriving unit. The cleaning unit is installed on one sun-facing side of the photovoltaic panel. The water adding unit is installed on a back side of the photovoltaic panel. The driving unit is installed on a back side of the water adding unit, attracting force of an electromagnet is used in the driving unit to drive a water tank upward to spray water on the photovoltaic panel. A cleaning roller isdriven to clean the surface of the photovoltaic panel in a rotating manner, a cleaning step of the cleaning roller is effectively combined with a water spring step, the surface of the photovoltaic panel can be cleaned rapidly, and used water can be recovered and reused after the cleaning step to improve utilization rates of water resources.
Description
technical field [0001] The invention relates to the technical field of photovoltaic applications, in particular to a solar tracking photovoltaic power generation device. Background technique [0002] In today's world, the energy crisis and environmental pollution problems have attracted more and more attention. As a new type of renewable energy, solar energy is widely used due to its environmental friendliness. Photovoltaic power generation uses the photovoltaic effect of the semiconductor interface to generate A technology that directly converts light energy into electrical energy. It is mainly composed of three parts: solar panel components, controllers and inverters. The main components are composed of electronic components. The solar cells are packaged and protected after being connected in series to form a large-area solar cell module, and then cooperate with power controllers and other components to form a photovoltaic power generation device. [0003] After the pho...
