Building outer wall surface intelligent cleaning equipment for teaching and training

The invention belongs to the field of building outer wall cleaning, and particularly relates to building outer wall surface intelligent cleaning equipment for teaching and training. The equipment comprises a six-joint mechanical arm, an execution end mechanism, a water tank, a water pump A and a water pump B. In the process that the execution end mechanism sucks and recycles sewage generated after curtain wall cleaning, large dregs in the sewage are blocked and retained at the bottom of the precipitation cavity by the bristles in the precipitation cavity, after the execution end mechanism is separated from the curtain wall, a flushing groove in the side wall of the cleaning seat and a dreg discharging groove in the bottom of the precipitation cavity are automatically opened, and the execution end mechanism runs in water containing less dregs to discharge the dregs accumulated in the precipitation cavity along with the water. And therefore, the execution end mechanism is ensured to continuously perform effecti
