In the scrubbing mode: when the road surface is cleaned, the negative pressure suction and pickup are carried out by the fan twice, the operation speed is 15km/h, and a certain amount of garbage (such as 400 g/m) is arranged on the road surface2Left and right), the main fan 6 performs primary suction at a certain rotation speed (such as 2000-2600 rpm) to suck eighty to ninety percent of garbage, silt and sewage; the multifunctional suction nozzle 7 moves forwards, the auxiliary fan 9 rotates at a certain rotating speed (such as 2000-2600 rpm), secondary suction is carried out immediately, garbage, silt and sewage which are leaked in the primary suction and pickup process are sucked and picked up again, the road surface is cleaned, and the operation is completed.
2. Operation in winter:
in the sweeping mode: when the temperature is low in winter (for example, -10 ℃), the pipeline heating and heat-insulating system 13 of the whole vehicle works to ensure that the sweeping disc dust-settling waterway pipeline is not frozen when being normally used, when the road is cleaned, negative pressure suction is carried out by the fan twice, the operation speed is 15km/h, and when a certain amount of garbage (for example, about 500g/m 2) is on the road, the primary suction is carried out by the main fan 6 at a certain rotating speed (for example, 2000-2600 rpm), and eighty to ninety percent of the garbage and silt are sucked away; the multifunctional suction nozzle 7 moves forwards, the auxiliary fan 9 rotates at a certain rotating speed (such as 2000-2600 rpm), secondary suction is carried out immediately, garbage and silt which are leaked in the primary suction and pickup are sucked up again, the road surface is cleaned, and the operation is completed. After the operation is finished, the water in the pipeline is discharged firstly, then the one-key water blowing system 12 is used, the water in the pipeline can be blown away, the vehicle can be stored without frost damage due to low temperature, and the vehicle can work normally again the next day.
In the scrubbing mode: the pipeline heating and heat-insulating system 13 of the whole vehicle works to ensure that the high-pressure cleaning water channel and the dust-settling water channel of the sweeping disc can not be frozen when being used normally, and simultaneously, the air heater 14 is started, and hot air enters the heating cavity 74 of the multifunctional suction nozzle 7 through the blowing pipe 17. When the road surface is cleaned, the fan is used for negative pressure suction and pickup twice, when the operation speed is high, and when the road surface has a certain garbage amount (such as about 400g/m 2), the main fan 6 carries out primary suction and pickup according to a certain rotating speed (such as 2000-2600 rpm), and eighty percent to ninety percent of garbage, silt and sewage are sucked away; the multifunctional suction nozzle 7 moves forwards, the auxiliary fan 9 rotates at a certain rotating speed (such as 2000-2600 rpm), then secondary suction is carried out, garbage, silt and sewage which are sucked and picked up at one time and leaked are sucked into the auxiliary garbage box 82, and the road surface is cleaned; meanwhile, the hot air blown out from the hot air blower 14 is sprayed to the twice sucked and picked road surfaces from the heating cavity 74 to heat the road surfaces, the residual water on the road surfaces is taken away by evaporation, and the evaporated water vapor flows to the secondary sucking and picking cavity 72 and is sucked into the secondary dustbin 82. And the hot air discharged by the auxiliary fan 9 can enter the box body separating cavity 83 at the periphery of the main garbage can 81 to heat the main garbage can 81, so that the main garbage can 81 can not be frozen in low-temperature operation in winter. After the operation is finished, the water in the pipeline is discharged firstly, then the one-key water blowing system 12 is used, the water in the pipeline can be blown away, the vehicle can be stored without frost damage due to low temperature, and the vehicle can work normally again the next day.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
