Abstract

The invention provides a high-low pressure urban road cleaning sprinkler which comprises a sprinkler body, a cleaning frame, a first spray pipe, a second spray pipe, a converter, a high-pressure pump and a low-pressure pump. The invention provides a high-low pressure urban road cleaning sprinkler which is provided with a converter arranged between a first spray pipe and a second spray pipe, wherein the converter comprises a high-pressure pipe, a low-pressure pipe and a control valve with two ends communicated between the high-pressure pipe and the low-pressure pipe. When the control valve is in an open state, the high-pressure pump or the low-pressure pump independently operates, so that the first spray pipe and the second spray pipe can simultaneously circulate a high-pressure water source or a low-pressure water source. When the high pressure on the low pressure right side of the single side left side is needed, the control valve can be closed, and the high pressure pump and the low pressure pump are opened simultaneously, so that the first spray pipe circulates a low pressure water source, the second spray pipe circulates a high pressure water source, the water pressure can be adjusted according to different conditions on site, and the road cleaning device is suitable for road cleaning under different working condition environments.

Background The cleaning and maintenance of urban roads are important links for maintaining urban environments and guaranteeing traffic safety. At present, road cleaning sprinkler trucks commonly used in the market mostly adopt fixed or high-low voltage switching systems for operation. The typical mode of operation is to flush and dust the pavement by side spraying with a relatively constant medium and low pressure water stream. At present, however, road cleaning conditions are diversified, for example, the road shoulder position is difficult to clean relative to the position in the middle of the road, when low-pressure cleaning is adopted, the ground at the road shoulder cannot be effectively cleaned, and when a high-pressure mode is adopted, the water delivery quantity at two sides of the cleaning vehicle is increased, so that the water source is wasted.
