Description
Technical Field
The invention relates to the technical field of photovoltaic module cleaning, in particular to an intelligent photovoltaic cleaning robot system for detecting and automatically cleaning attachments on the surface of a photovoltaic module of a power station.
Background
In recent years, solar energy is used as clean energy on the premise that the nation increasingly pays attention to environmental protection, and photovoltaic power stations are more and more constructed. The photovoltaic module is an outdoor device, and dust on the surface of the photovoltaic module in a natural environment is mainly classified into sand dust and scale. The cleaning of the photovoltaic module is very necessary, on one hand, when the photovoltaic module is placed in the air for a long time for generating electricity, a large amount of dust in the air can cover the surface of the photovoltaic module and block part of solar radiation, so that the effective area irradiated to the surface of the photovoltaic module is reduced; on the other hand, the dust affects the transmittance of silicon crystals on the surface of the photovoltaic module, and the higher the deposition concentration of the dust is, the lower the transmittance of the panel is, and the lower the solar radiation absorbed by the panel is. The solar irradiation amount received by the photovoltaic module is reduced, and the photovoltaic power generation efficiency is reduced along with the solar irradiation amount. When the area of the photovoltaic module is covered by dust, the covered part can not work normally, and meanwhile, heat can be prevented from being transferred outwards, after long-time sunlight irradiation, the temperature of the covered photovoltaic module is far higher than that of the part which is not covered by the dust due to the fact that the heat can not be transferred outwards in time, burning hot spots can occur on the surface of the photovoltaic module when the temperature is seriously too high, and the burning hot spots can cause large-area damage to the photovoltaic module when the burning hot spots are serious.
Currently, the following cleaning methods exist for photovoltaic module cleaning:
and (5) naturally cleaning. The natural cleaning is to remove dust on a photovoltaic module panel by utilizing the rainwater weather, wind power and the like of the nature, the rainfall and wind power dust removal are more suitable for the southern with more rainwater weather in China, the rainfall in the northwest is less than the drought wind resource, so the rainfall and wind power dust removal cannot be equivalently realized, the accumulated dust of the photovoltaic module in the northwest is mainly floating dust, the floating dust can be partially removed by means of the wind power, and the photovoltaic module can not be effectively applied by eating the weather.
And (5) manually cleaning. The manual cleaning is to use common cleaning tools (a velvet mop, a hair drier and a velvet rag) manually, the surfaces of the photovoltaic components are cleaned by the aid of the tools, a cleaning person adopts the long-handle velvet mop to clean the surface by matching with special dust cleaning agent, the cleaning work cycle is about 1MW for 4 persons/day according to the proportion of hired workers, 20 days are consumed for a 20MW power station, and the cost is about 1.6 ten thousand yuan to 1.8 ten thousand yuan.
In summary, the floating dust on the surface of the photovoltaic module has a great influence on the luminous flux and the temperature. According to the actual operation condition of a certain power station, under the condition of good irradiance, the power generation efficiency is obviously improved (8-12%) the next day after the assembly is washed by rain, and the effect of natural rainwater dust removal is obvious. However, because the photovoltaic panels are installed on the floating balls on the water surface in a large number, the dust can be removed only by adopting a manual scouring mode at present, the dust removal difficulty is high, the efficiency is low, and the workload is huge.
