Background

In order to ensure good operation environment and operation safety of the subway, the subway tunnel must be cleaned. The cleaning environment of the subway tunnel is more complex than that of a common road and is difficult to clean, and especially, electric appliances such as cables and signal boxes are often arranged in the subway inter-rail area and the wall surface of the tunnel, and the cleaning operation effect is affected by facilities such as trenches, rails and spikes.

At present, the pneumatic cleaning method adopted by the cleaning device at home and abroad has three forms: 1) the broom is used for driving the ground garbage, and the garbage is sucked into the garbage can through the suction nozzle; 2) flushing the ground through water power, and sucking the residual garbage into the garbage can through the suction nozzle; 3) the relative position of the blowing nozzle and the suction nozzle is fixed, the blowing nozzle is used for blowing up the garbage from the ground, and then the garbage is sucked into the garbage can along with the air flow through the suction nozzle. Among them, the performance of the electric appliances is affected by the movement of the broom, and even the subway operation is affected or traffic accidents are caused when the electric appliances are seriously touched; moreover, when the broom drives the garbage, flying dust is easy to fly into the atmosphere to cause secondary pollution, and even if water is sprinkled to prevent the secondary pollution from occurring when the broom is used for sweeping, the garbage such as dust and the like is wet and adhered to the ground and cannot be sucked into the suction nozzle. The hydraulic flushing easily causes the wet and slippery ground and the moisture of air, so that the electric appliances in the subway tunnel are easy to rust or leak electricity; and also has the problem of water resource waste. The mode that the position of the blowing and suction nozzle is relatively fixed is generally only suitable for wide and relatively flat roads, and is difficult to be suitable for cleaning complicated inter-rail areas and tunnel wall surfaces, so that the cleaning efficiency is low. In addition, in the prior art, the exhaust gas of the dust remover is introduced into the road surface to be cleaned through a pipeline to blow up the road surface garbage, so as to assist the dust suction nozzle in dust suction, but the method has no air path switching mechanism and leads to a fixed blowing and suction path; the air nozzle can not blow air effectively at a flexible position, so that the blowing and sucking combination can not adapt to complex cleaning working conditions well; and because there is not special air cock and makes the strength not enough, lead to rubbish such as some dust particles to be difficult to start to clean inefficiency.

Therefore, the cleaning efficiency and the cleaning effect of the existing cleaning scheme can not meet the requirement of cleaning a complex road surface, especially the complex environment of a subway tunnel.
