[0002] In industrial production sites such as large power plants and steel mills, during the emission process of a large amount of flue gas generated by burning fossil fuels, it will continuously accumulate and adhere to the inner wall of the flue. As the usage time of the flue increases, the dust and dirt in the flue will become thicker and thicker, resulting in a weakened emission capacity of the flue, and even the situation of flue blockage. Once the flue is blocked, the factory will be unable to operate, causing serious economic losses. At present, the flue cleaning work is mainly completed manually, but it is extremely easy to cause dust during the cleaning process, and the closed environment in the flue has a serious impact on the health of the cleaning workers. Therefore, there is an urgent need for an automatic, efficient, and safe flue cleaning device. Summary of the Invention
