Due to the continuous investment of domestic and related enterprises in the field of intelligent manufacturing, combined with various operation and maintenance of photovoltaic power stations, intelligent equipment such as drone detection and photovoltaic cleaning robots have been developed and applied in the field of photovoltaic operation and maintenance. The photovoltaic cleaning robot has the advantages of waterless cleaning, intelligent control, unmanned monitoring, free setting of operating parameters, and convenient charging. For household products, the components can be cleaned basically without manual intervention. Robots can save a lot of labor in large power stations. Of course, the robot still cleans foreign objects semi-automatically.
There are many types of cleaning robots in distributed power stations, and the component configuration of the distributed power stations limits the cleaning range and distance of the robots to a certain extent. If the scene is complicated, the robot equipment needs to be customized. The color steel tile roof has a history. After many years of updating the robot equipment, it is necessary to consider the second disassembly and assembly.
There are many cleaning methods for photovoltaic modules according to the type of power station. For example, a semi-automatic cleaning truck can be used to clean large ground power stations, as shown in Figure 1. The invention is only suitable for power stations with flat ground and large slope. The venues must be within an acceptable range, and the distance between the venues must be large enough to ensure that clean vehicles can pass. Cannot be used for steep slope or mountain power station.
Outdoor power generation usually installs solar components. Due to the unsatisfactory outdoor environment, pollutants and dust are likely to fall on the glass surface of the module. The accumulation of dust to a certain extent will affect the power and performance of the module. Some influencing dust not only reduces the effective radiation reaching the glass, but also affects the heat dissipation of the parts. If the fouling is particularly serious, it will also have a thermal effect. Photovoltaic power plants near some chemical plants can also corrode glass.
In order to ensure the long-term reliability of the equipment, can it be ensured that the investment and income of the equipment will meet expectations during the normal working life cycle. The key components are the motors, brushes and batteries of the photovoltaic cleaning robot.
