[0002] Photovoltaic is a clean energy source that is increasingly being put into use. Photovoltaic power stations are generally built in the central and western regions of my country. Although there are abundant light resources, there are also problems with strong winds and sand. If dust is deposited on the photovoltaic panels, it will seriously affect the power generation efficiency of the photovoltaic panels, and even cause local hot spots and damage. Therefore, it is particularly important to regularly clean and maintain the photovoltaic panels.

[0003] Most of the existing cleaning methods are manual cleaning. Since photovoltaic fields generally have a large number of photovoltaic panels and are located in remote areas, manual cleaning is not only time-consuming and labor-intensive, but also inefficient and has high labor costs. With the development of technology, more cleaning equipment has emerged. Most of them use vacuum suction cups to fix them, which has a slow cleaning speed. Some technologies use hanging wheels to hang on the side frames of photovoltaic panels for walking cleaning. The speed is much faster than that of vacuum suction cup series cleaning equipment, but the disadvantages are also obvious. It is often easy to fall off in windy weather, and it is easy to deviate and fall off during walking. These problems need to be further improved. Summary of the invention
