Description

An automatic exterior wall cleaning machine

technical field

The invention relates to an automatic cleaning device, in particular to a device for cleaning the outer walls of high-rise buildings.

Background technique

The building is exposed to the air, and its outer wall is easily polluted under the attack of wind, rain and smoke. Dust and oily smoke adhere to the surface of the building, making the outer wall yellow and black, which is extremely unsightly. In order to keep the city clean and beautiful, the exterior wall of the building must be cleaned once in a while. With the rise of skyscrapers, high-rise buildings have sprung up in various urban areas around the world, with more than 20 or 30 floors. The high-rise buildings are more obvious in large and medium-sized cities, and high-rise cleaning companies around the world have emerged as the times require. However, at present, the cleaning of the exterior walls of high-rise buildings in China mainly relies on "spiderman" or a simple hanging frame to carry people to carry out manual operations. Such tools manually clean the metope, and its labor intensity is big, work efficiency is low, safety is poor, and modern high-rise building is extremely uncoordinated.

The above are the deficiencies in the actual implementation of the traditional high-rise exterior wall cleaning method. Based on the existing problems in this situation, there is an urgent need for an exterior wall cleaning equipment that can be directly operated at high altitude without people.
