Description

A solar power panel cleaning vehicle with a waste water recovery device

technical field

The utility model relates to the energy field, in particular to a solar power generation panel cleaning vehicle with a waste water recovery device.

Background technique

With the development of economy and progress of society, people put forward higher and higher requirements for energy. The existing sources of electric energy mainly include thermal power, hydropower and nuclear power. Thermal power is facing the danger of depletion of fossil fuels and is charged with deteriorating the global environment. Hydropower will cause environmental damage and be affected by seasons. Although nuclear power is clean energy, nuclear safety is still an international issue. Therefore, the search for new energy sources has become an urgent issue facing mankind. Solar energy is the most likely alternative to traditional energy nowadays, and solar photovoltaic power generation is one of the important means to utilize solar energy by photoelectric conversion. Because it is green, clean and renewable, with the further improvement of photoelectric conversion efficiency in the near In the future, it will surely occupy an important seat in the world's energy consumption.

At present, the collection of solar energy is mainly realized by solar panels. Solar panels are usually installed in open, sunny areas. However, in long-term use, it is inevitable that birds, dust, fallen leaves and other shelters will fall on them, and these shelters will form shadows on the solar panels. These partial shadows will cause the current and voltage of some cells in the solar panel to change. This results in a localized temperature rise on these battery components, known as the "hot spot effect". In the actual use of solar cells, if the temperature generated by the hot spot effect exceeds a certain limit, the solder joints on the cell components will melt and the grid lines will be destroyed, resulting in the scrapping of the entire solar cell component. According to foreign authoritative statistics, the hot spot effect reduces the actual service life of solar cell components by at least 10%.

Regular cleaning of solar panels can effectively avoid hot spot effects. Experimental data shows that formulating a reasonable cleaning and cleaning plan can increase the economic efficiency of the power plant by more than 20%. To reasonably solve the problem of dust on battery panels, we must first pay attention to formulating a reasonable cleaning time schedule according to local comprehensive conditions. Secondly, the cleaning must be clean and thorough. If a dead angle is left, it may still cause serious consequences such as "hot spot effect". Choosing the correct cleaning tools and methods when cleaning can improve the life of the battery board. The surface of solar cells is made of high-strength tempered glass, which also has the problem of wear and tear. The service life of solar power generation panels is more than 20 years. In order to ensure normal power generation, it is generally cleaned once or twice a month. If the methods and tools used are inappropriate, it is easy to cause the surface of the battery to be worn, affecting the power generation capacity and the life of the battery board product. At the same time, it is also very important to solve the cleaning problem of solar photovoltaic power plants in winter and snow seasons. In the winter snow season, the battery components cannot be cleaned with water. In some seasons, there is still the problem of condensation and freezing on the battery board. Equipment with snow removal, dew removal, deicing, and waterless cleaning functions should be used.

The traditional cleaning method is manual cleaning. However, solar power panels are often placed at an angle, and the height difference is often three or four meters. The highest point is often a dead corner that cannot be cleaned manually or is not easy to clean. At the same time, there is a certain risk of falling when manually cleaning the highest point. Thirdly, manual cleaning has certain uncertainties. For example, the cleaning workers subjectively think that they have been cleaned, but the actual situation is not up to standard, or the cleaning workers are tired after working for a long time, resulting in low cleaning quality, and even some lazy workers do not go to the cleaning site at all. Clean the upper part of the solar panel. These will reduce the efficiency and even life of solar power generation.

The utility model intends to design a device that can wash solar power generation panels. The device has a high degree of automation and is suitable for washing a large number of solar power generation panels in solar photovoltaic power plants. The power generation board is cleaned, and the rail cleaning vehicle travels on the track laid in advance beside the solar power generation board, and at the same time washes the solar power generation board. There are five processes of photographing, spraying organic solvent, spraying water, wiping and blowing on the board.
