A self-cleaning system for photovoltaic modules

Abstract

The invention discloses a photovoltaic module self-cleaning system, which belongs to the field of photovoltaic module cleaning. The photovoltaic module self-cleaning system of the present invention comprises a cleaning module arranged at the upper end of the photovoltaic module, a sewage suction module and a control module arranged at the lower end of the photovoltaic module, the sewage suction nozzle of the sewage suction module is connected with the water suction pump through the sewage suction pipe, and A rotating brush is arranged on the upper part of the suction nozzle. The surface of the inclined photovoltaic module is rinsed from top to bottom through the cleaning module with spray flushing function, and the flushing sewage is sucked out through the sewage suction module with active suction function, and at the same time, it cooperates with the rotation of the sewage suction nozzle The brush cleans the bottom, so that the entire photovoltaic module can be cleaned from top to bottom, and effectively prevents the deposition of dust on the bottom of the photovoltaic module, improving the overall cleaning effect of the photovoltaic module. The whole cleaning system has simple structure, low cleaning cost and high cleaning efficiency. High efficiency, good cleaning and water saving, and high degree of automation.

Description

technical field [0001] The invention relates to the field of photovoltaic module cleaning, in particular to a photovoltaic module self-cleaning system. Background technique [0002] In recent years, the country has vigorously advocated environmental protection and clean energy. Solar energy is the most convenient clean energy, and more and more photovoltaic power plants are being built. If the photovoltaic module is placed in the air for a long time, a large amount of dust in the air will cover the surface of the photovoltaic module, blocking part of the solar radiation, thereby reducing the effective area irradiated on the surface of the photovoltaic module. At the same time, the dust will also affect the silicon crystal on the surface of the photovoltaic module. Therefore, the solar radiation received by the photovoltaic module is reduced, and the efficiency of photovoltaic power generation is reduced accordingly. In addition, when part of the area of ​​the photovoltaic m...

Problems solved by technology

[0005] 1. The sewage collected in the waste water collection tank flows into the filter device by the gravity of the water itself. The water flow rate is slow, and the dust in the sewage is easy to deposit at the bottom of the waste water collection tank. Long-term operation will easily lead to the blockage of the waste water collection tank and lose the waste water collection function;

[0006] 2. The nozzle sprays water from the top of the photovoltaic module to clean, while at the lower part of the photovoltaic module, the scouring effect of the water flow is reduced, mainly relying on the gravity flow of the water itself, so dirt and dirt are easy to accumulate at the lower end of the photovoltaic module, making the cleaning effect of the lower part of the photovoltaic module relatively poor.
