Description

technical field [0001] The invention relates to a cleaning system, in particular to a photovoltaic panel cleaning robot and an intelligent cleaning system with a monitoring function for cleaning dust on the surface of photovoltaic panels, belonging to the technical field of photovoltaic power station operation and maintenance. Background technique [0002] In photovoltaic power generation applications, photovoltaic panels are the source of electricity generation, and dust on photovoltaic panels will reduce the photoelectric conversion efficiency of photovoltaic power generation. There are two main types of dust: [0003] 1. Floating dust: The particles are small and easy to adhere to the photovoltaic panel. The process of attachment is a physical process; the frequency of floating dust is high, but it is relatively easy to remove; [0004] 2. Fouling: Wetting by rain or absorbing moisture in the air, the dust particles will become more sticky to the photovoltaic panel after...

AI Technical Summary

Problems solved by technology

[0003] 1. Floating dust: The particles are small and easy to adhere to the photovoltaic panel. The process of attachment is a physical process; the frequency of floating dust is high, but it is relatively easy to remove;

[0004] 2. Fouling: Wetting by rain or absorbing moisture in the air, the dust particles will become more sticky to the photovoltaic panel after being damp, and will also absorb impurities floating in the air and adhere to the photovoltaic panel; the final shape will change. In the form of points, flakes and strips, it is relatively hard; the probability of fouling is low, but it is not easy to find in time, and it is also difficult to remove;

[0006] 1. Blocking light: Dust will block the light shining on the photovoltaic panel, and the area of ​​the photovoltaic panel receiving solar radiation will be reduced; it will also reduce the transmittance of the glass, thereby affecting the efficiency of photovoltaic power generation;

[0007] 2. Hot spot effect: When part of the photovoltaic panel is covered by dust for a long time, it cannot work normally; under continuous sunlight, the temperature rise of the covered part will be much greater than that of the uncovered part, resulting in the temperature of the covered part being too high And burnt dark spots appear, which will lead to large-scale damage to solar cells in severe cases;

[0008] 3. Acid and alkali erosion: When the dust with acid and alkali characteristics is deposited on the surface of the photovoltaic panel, the dust will gradually erode the surface of the photovoltaic panel, causing permanent damage to the surface of the photovoltaic panel and reducing the efficiency

[0010] 1. Traditional manual washing and cleaning: low efficiency, high labor cost, mediocre cleaning effect, and serious waste of water resources;

[0011] 2. Photovoltaic panel cleaning robot: also known as on-chip robot (such as figure 1 shown); for example, Chinese patent CN103406292A discloses a "photovoltaic module cleaning robot"; the advantage of this type of robot is that it has a high degree of automation and can effectively remove floating dust, but the disadvantage is that the cleaning effect on fouling is general;

[0015] 3. Vehicle-mounted mobile cleaning machine: high efficiency, small water consumption, can effectively remove floating dust and scale; the disadvantage is that the scale cannot be accurately treated, the energy consumption is high, and a certain amount of manpower and operation and maintenance management are required

[0017] 1. Traditional manual detection: low efficiency, time-consuming and laborious, and inaccurate detection;

[0018] 2. UAV patrol inspection: Although the efficiency has been greatly improved, its disadvantages are high cost, low image data accuracy, short battery life, and affect the application effect
