When the sweeper is started to stop or runs in a non-operation state, the lifting driving mechanism 12 is ventilated, the lifting driving mechanism 12 is contracted, the expanded sweeping mechanism is tilted upwards, and the expanded sweeping mechanism is ensured not to influence the uphill or downhill running of the sweeper to the maximum allowable limit; a piston rod of the expansion driving mechanism 8 is in a contraction state, and the expansion cleaning mechanism is flush with the main cleaning mechanism; the opening driving mechanism 7 on the side spraying water removing mechanism is kept extending in the ventilation state, the water broom is parallel to the driving direction of the automobile, and the side spraying water removing mechanism on the right side is in a state shown in fig. 3.

When cleaning operation is needed, the road cleaning device falls to the ground, if a narrow road is cleaned, only the main cleaning mechanism is needed to complete the cleaning task, the lifting driving mechanism 12 keeps ventilation, the piston rod is contracted, the expanding cleaning mechanism is lifted up and is not contacted with the ground, the water broom is in an inoperative state (as shown in a state of a side spraying water-removing mechanism on the right side in fig. 3), and the sweeper moves forward for cleaning. When the road surface needs to be deeply cleaned in a road section with slag soil, mud or dirt with strong adhesion to the ground and difficult cleaning or thick dust on the road surface, high-pressure water can be input into the rotary spray rod mechanism, under the action of high-pressure water, the rotary nozzles 300 on the rotary spray rod 3 spray fan-shaped water curtains, and because the two nozzles on the rotary spray rod 3 are arranged at a certain angle, the rotary spray rod 3 rotates at high speed under the reaction force of strong pressure spray, and the sprayed water curtains continuously impact and wash the ground, during the cleaning process, the fan is in a working state to strongly suck sewage and other pollutants on the ground, so that the cleaned ground is always kept in a clean and waterless state, restoring the natural color of the road (the operation speed is kept within 5Km/h according to the condition of the road surface for cleaning), and stopping inputting high-pressure water into the rotary spray rod 3 after cleaning and pumping; after the pavement is deeply cleaned once, because pollutants in gaps of the pavement are basically removed, when the residual quantity of dust on the pavement exceeds the standard and no adhesive force is applied to the ground, the dust is easily raised, and at the moment, cleaning is carried out for two times or four times in the following process, high-pressure water is input into the quick cleaning spray rod 17, a nozzle on the quick cleaning spray rod 17 sprays a fan-shaped water curtain to wash the ground, and the two water curtains between two adjacent water curtains are ensured to have an overlapped part so as to ensure that the water curtains are completely cleaned (the operation speed is over 5 Km/h).

Taking the expansion driving mechanism 8 as an oil cylinder as an example, when the width of a road needs to be met for cleaning, and the cleaning width needs to be locally widened, the lifting driving mechanism 12 is cut off air, the piston rod extends under the action of the acting force of a spring in the lifting driving mechanism 12 and the gravity of the expansion cleaning mechanism, the expansion cleaning mechanism can freely fluctuate along with the concave-convex of the ground under the connection of the guide sleeve 10 and the guide rod 11, the expansion cleaning mechanism can be tightly attached to the ground when the ground is uneven, the cleaning effect is good, and the width of the cleaned road surface is adjusted on line by controlling the extension amount of an output shaft of the expansion driving mechanism 8 (oil cylinder).

When the road edge stone and the roadside are to be cleaned, the opening driving mechanism 7 is driven to drive the water broom to rotate and extend out of the expanding cleaning mechanism, the splash guard 15 is manually installed (the splash guard 15 is used for blocking impurities such as soil sprayed by the side spraying and water repelling mechanism and splashed on the vehicle body), high-pressure water is input into the water broom, the end nozzle 500 on the water broom sprays a fan-shaped water curtain under the action of the high-pressure water and is used for cleaning the upper surface and the side surface of the road edge stone, an inner core in the nozzle can rotate to spray a conical hollow water ring to act on the road surface under the action of the high-pressure water, and pollutants such as floating dust, scale, silt and the like on the road surface and a white solid line of the road surface are thoroughly cleaned under the impact and flushing of the high-pressure sprayed water ring to the ground, so that the natural color. The water broom shown in fig. 7 forms a certain included angle with the road edge stone, so that sewage sprayed and cleaned by the water broom in the walking process can be driven to the lower surface of the base 1 to be sucked away, when the water broom meets a sewer, a part of sewage can be driven to the sewer, and the cleaned road surface can not have sewage belts and sludge residues. When the side road surface without the curbstone is cleaned, the end nozzle 500 of the water broom also plays a role in cleaning the road surface, and the width of cleaning the road surface is increased.

It should be noted that, although the above embodiments have been described herein, the scope of the present invention is not limited thereby. Therefore, based on the innovative concept of the present invention, the changes and modifications of the embodiments described herein, or the equivalent structure or equivalent process changes made by the contents of the specification and the drawings of the present invention, directly or indirectly apply the above technical solutions to other related technical fields, all included in the scope of the present invention.
