Description
Technical Field
The application relates to the technical field of curtain wall cleaning, in particular to a glass curtain wall cleaning machine capable of automatically replacing a cleaning brush.
Background
Along with the rapid development of society, curtain wall use of high-rise buildings is gradually increased. Compared with the traditional outer wall, the glass curtain wall is outdoor for a long time, and is more easily polluted by dust, haze, sand storm, bird droppings and the like in the air. These contaminants can deposit on the surface of the glass curtain wall, greatly affecting the aesthetics of the building. Therefore, it is necessary to regularly perform cleaning work on the curtain wall.
At present, the cleaning work of the high-altitude glass curtain wall in the city is mainly manual cleaning, and the cleaning mode has high cleaning efficiency but good cleaning effect, and has a certain danger, and the high-altitude air flow disturbance can cause the workers and tools to swing greatly, so that the workers lose balance; the cleaning tool used by the worker runs the risk of falling off, possibly injuring nearby pedestrians. In addition, the labor cost of workers is also increasing. Therefore, it is a great trend to replace the manual work by curtain wall cleaning machines.
Generally, contaminants on the curtain wall surface can be classified into electrostatic adsorption type and chemical bonding type according to the adhering manner. Wherein the electrostatic adsorption type pollutant is generally smaller floating dust, is easier to remove, and the chemical bonding type pollutant is generally more firmly adsorbed. There are two main ways of removing contaminants: the water washing mode is more in line with the requirements of energy conservation and emission reduction because a large amount of water is consumed and the water washing mode is not needed. In brushing, typically, the brush is rotated, and the cleaning efficiency of the brush is different for pollutants with different adhesive forces. For example, a soft bristle brush has a better cleaning effect on floating dust and a poor cleaning effect on firmly adhered bonds, while a bristle brush is the opposite.
The rotating brush of the existing rotating brush type curtain wall cleaning machine is fixed and not replaceable, so that the existing rotating brush type curtain wall cleaning machine is poor in surface cleaning effect on complex pollutant distribution. Therefore, the brush can be flexibly selected according to the attachment mode of pollutants, and the cleaning efficiency and the cleaning effect of the rotary brush can be effectively improved.
