Description

Technical Field

[0001] The invention relates to the technical field of bus washing, in particular to a mobile bus quick washing device based on centrifugal force. Background Art

[0002] The bus has a huge impact on society and plays the most basic role in promoting urban development. The bus allows citizens to experience unprecedented closeness to each other, shortens the distance between the city and neighboring towns, and makes travel more frequent. After the bus is used, stains will form on the outer surface, which needs to be cleaned regularly. After searching, the patent with publication number CN218640823U discloses a bus cleaning machine. When in use, first turn on the drive motor to make it rotate, then drive the roller to keep rotating, and then turn on the electric drive wheel to provide a power source. By manually pulling the operating handle and adjusting the switch, the bus cleaning machine can be controlled to move around the bus. During the movement, the operating handle can be rotated to change the movement trajectory of the bus cleaning machine. At the same time, the rotating roller will drive the bristles to rotate, and the bristles will rub against the surface of the bus, so that the bus can be scrubbed at all angles. The water source is transported through the water outlet pipe, and sprayed on the surface of the bus by the nozzle on the front side, cooperating with the bristles to scrub the bus, and then the nozzle on the rear side sprays water for two times. The invention relates to a method for cleaning the bus by spraying water directly onto the bus. However, this method is not convenient for cleaning the brush. The water is directly sprayed onto the bus. Since there will not be too much residue after the water is sprayed onto the bus, most of the water will overflow downward. In order to ensure that there is a certain amount of water on the bus when the brush cleans the bus, more water will be sprayed to ensure the cleanliness of the cleaning, which consumes a lot of water. At the same time, when the brush is dirty, it will bring back part of the dirt after it rotates back, and it needs to contact with the water sprayed onto the bus for a period of time before it can continue to keep clean, which increases the cleaning time and water waste. Therefore, a mobile bus quick cleaning device based on centrifugal force is designed, which is convenient for spraying water onto the brush, keeps the brush clean for cleaning the bus, reduces the waste of water resources, and improves the cleaning efficiency.
