Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail.Should be understood that, detailed description of the invention described herein, only for instruction and explanation of the present invention, is not limited to the present invention.
In the present invention, when not doing contrary explanation, the noun of locality of use is as normally undefined at normal transport condition at clean vehicle provided by the invention in " upper and lower, forward and backward, ", i.e. direction illustrated in fig. 2.
As shown in Figure 1, according to an aspect of the present invention, provide a kind of road surface of pavement cleaning vehicle to wash the method for sweeping, this pavement cleaning vehicle comprises dampening system and purging system, this road surface clean method comprises: wetting, sprays moisture with wetting road surface by dampening system on road surface; Cleaning, uses the current that eject of purging system to clean the road surface after wetting.
In technique scheme, due to before the cleaning step of road pavement, adding moistening step can be immersed in wetting moisture by the rubbish be deposited on road surface, can become soft and be partly dissolved in wet water, and the mobility of these rubbish can be improved, make in the cleaning in later stage, can effectively these rubbish be cleaned up.
In order to effectively complete the wetting operation of road pavement, preferably, in wetting, by uniform moisture spread on road surface.Wetting fully to make the garbage energy on road surface access, increase the effect of the cleaning in later stage.In addition preferably, in wetting, on road surface, the water yield of unit area is 0.1L/m
2-0.16L/m
2., show through great many of experiments, the water yield in this numerical intervals can either soak fully to making the rubbish on road surface, does not waste water source again.
In addition, this pavement cleaning vehicle also comprises purging system, also comprises before road pavement is cleaned: cleaning, uses purging system road pavement to clean.This purging system can coil assembly or rolling and brushing assembly etc. for being arranged on sweeping below vehicle chassis.
Cleaned by High-Pressure Water road pavement again after cleaning, the cleannes on road surface are strengthened greatly.
In order to improve the present invention, this pavement cleaning vehicle also comprises rubbish and waste water recovery system, also comprise after road pavement is cleaned: suction, adopt recovery system to be drawn in dustbin by the sewage on road surface and rubbish, the rubbish after making to remain in cleaning on road surface is thoroughly cleaned.
Therefore, road surface provided by the invention is washed the method for sweeping and is made Street surface cleaning better effects if, has very strong practicality and promotional value.
According to a further aspect in the invention, as shown in Figures 2 and 3, provide a kind of pavement cleaning vehicle, this pavement cleaning vehicle comprises dampening system, purging system, purging system and recovery system.Dampening system is tentatively moistening for carrying out before road cleaning, the wetting nozzle 1 for spraying water that it lower end, front side comprising this pavement cleaning vehicle is arranged, for by water from dustbin 3 be delivered to wetting nozzle 1 wetting water pump 4 and respectively by the pipeline that wetting water pump 4 is connected with dustbin 3 with wetting nozzle 1, the operating pressure of this wetting nozzle 1 can be 0.4Mpa-0.8Mpa.This purging system is used for carrying out brute force cleaning to the road surface after wetting, and what it comprised actuating unit driving sweeps dish 5.This purging system is used for the road surface after to cleaning and carries out strong flushing, and it comprises washer jet 6, flushing water pump 8 and respectively by pipeline that flushing water pump 8 is connected with dustbin 3 with washer jet 6.This recovery system is used for being recovered in dustbin to the sewage of the rubbish cleaned and formation after rinsing, it water inlet blast pipe comprising suction nozzle 7, blower fan 9 and suction nozzle 7 is communicated with dustbin, blower fan 9 makes to produce negative pressure in dustbin 3, the sewage formed behind the water cleaning ground rubbish swept up through overscan dish 5, washer jet 6 sprayed, is drawn in dustbin 3 by suction nozzle 7 and water inlet blast pipe.
In technique scheme, this pavement cleaning vehicle can carry out for road pavement such as sweeper, cleaning Vehicle or sweeping machines common in environmental sanitation vehicles the vehicle that cleans.In the present invention, by the lower end, front side at pavement cleaning vehicle, wetting nozzle 1 is set, make before the cleaning of pavement cleaning vehicle starts, first road pavement soaks, as described in the first aspect of the invention, by wetting operation, can the rubbish be deposited on road surface be immersed in wetting moisture, can become soft and be partly dissolved in wet water, and the mobility of these rubbish can be improved, make in the cleaning in later stage, can effectively these rubbish be cleaned up.In addition, being 0.4Mpa-0.8Mpa by limiting the operating pressure of wetting nozzle 1, making the pressure of wet water can not be too high and rubbish is flushed to the both sides on road, cause secondary pollution, also can not be too low and make the poor effect that soaks due to hydraulic pressure.
