Description

Technical Field

[0001] The present invention belongs to the technical field of cleaning equipment, and in particular relates to a wall-mounted multi-roller photovoltaic cleaning device and a cleaning method. Background Art

[0002] As the global energy crisis and air pollution become increasingly prominent, traditional fuel energy is decreasing day by day, and the harm to the environment is becoming increasingly prominent. At this time, the world has turned its attention to renewable energy, hoping that renewable energy can change the energy structure of mankind and maintain long-term sustainable development. In recent years, clean energy has made great progress. The power supply structure has also changed greatly, and more and more natural energy is used to generate electricity.

[0003] Photovoltaic power stations of various forms have also been widely promoted. The number of large-scale photovoltaic power stations built and put into operation each year is increasing. In order to ensure the system efficiency of photovoltaic power stations and increase the power generation of power stations, a reasonable operation and maintenance plan should be formulated according to the environmental and climatic conditions of the power stations, which is the basis for their efficient and safe operation.

[0004] In particular, cleaning of photovoltaic panels is a must for photovoltaic power stations. Dust, flying birds and other crops on photovoltaic panels will affect normal power generation. It may even cause the photovoltaic panels to heat up and burn out. For photovoltaic power stations in Northwest China, dust shielding is an important factor affecting power generation. Northwest China is dry and water-scarce, with strong winds and sand, and the components are seriously shielded by dust. Figure 1 Dust shielding will reduce the amount of light radiation received by the module, affect system efficiency, and reduce power generation; local shielding will cause hot spot effects, resulting in power generation loss, affecting the life of the module and causing safety hazards.

[0005] Foreign countries have conducted experiments and found that although there are many factors that affect the power generation efficiency of solar panels for solar power generation, cleaning solar panels is a very important factor. If they are not cleaned, the power generation loss of solar panels can be as high as 25%. In some areas, according to reports from renewable energy laboratories in some European countries, individual solar power stations have lost up to 30%.

[0006] In addition to being affected by weather and environmental factors, the cleanliness of the photovoltaic panel surface is also an important factor in the power generation load and power. For the cleaning of photovoltaic panels, the traditional method is to use a telescopic pole equipped with a motor and a cleaning brush for manual cleaning. The equipment used in this cleaning method is heavy, and the operator needs to carry a battery pack on his back. Overall, it is not easy to use, and the labor intensity is high, the cleaning efficiency is low, and the cleaning effect is poor. It is only suitable for small photovoltaic power stations, but it is relatively clumsy for large-area matrix photovoltaic power stations.

[0007] For example, the patent No. 201610696893.7 discloses a wall-mounted photovoltaic panel cleaning device, which includes a cleaning robot, a mobile vehicle, and a track. The cleaning robot includes a brush plate, a first controller is provided on the top of the brush plate, a roller and several rows of cleaning brushes are provided on the bottom of the brush plate, infrared sensors and pressure sensors are symmetrically provided on the left and right sides of the brush plate, and drive motors are provided at the upper and lower ends of the brush plate, respectively, and each drive motor is connected to a walking pulley, and the infrared sensor, pressure sensor, and drive motor are respectively connected to the first controller; the mobile vehicle includes a lifting telescopic rod and an angle-adjustable shifting vehicle plate, the shifting vehicle plate is arranged at the upper end of the lifting telescopic rod, and the lower end of the lifting telescopic rod is connected to an electric running wheel, and the electric running wheel is arranged on the track, and a limiter is provided on the outer side of the shifting vehicle plate surface, and a second controller is provided on the shifting vehicle plate. Although this structure solves the problem of slow efficiency of manual cleaning, its cleaning effect still cannot meet current needs. Summary of the invention
