[0004] The above technical scheme is adopted to clean and maintain the roads, and the cleaning liquid output from the water tank is continuously received by the pressurized nozzle on the water dividing plate to keep the brush plate moist, which has a better cleaning effect on the roads, can better clean the stains on the roads, and the wear between the brush plate and the road in the wet state is lower. However, in the above technical scheme, when the road maintenance cleaning device is in use, it only washes the dust and mud on the road, and flushes the dust from the middle of the road to both sides of the road.

[0032] The working principle of the utility model is as follows: when in use, firstly connect the suction pump 5, the water pump 17, the liquid level meter 22 and the electromagnetic valve 23 to the power supply on the vehicle body 1. When it is necessary to clean and maintain the road, the suction force provided by the water pump 17 is used to draw out the water inside the water tank 2, and spray it onto the road surface through the three-way pipe 18 and the nozzle 19, so as to complete the cleaning and maintenance work of the road.
