Description

Technical Field

[0001] The utility model belongs to the technical field of guardrail cleaning equipment, and in particular relates to a water-saving guardrail cleaning vehicle. Background Art

[0002] Road guardrails are generally set in the middle of the road. They can play a role of separation, and can separate lanes in different directions. At the same time, they can also play a blocking function, which can block pedestrians, bicycles or motor vehicles trying to cross the road, thereby improving road safety and effectively improving traffic order. Because the guardrail is located in the middle of the road, it is easy for a large amount of dust to adhere to the guardrail, making the guardrail easily eroded by dust and very easy to oxidize, which reduces its protective ability. In the event of a traffic accident, the guardrail is often difficult to play the due buffering role, so the guardrail needs to be cleaned regularly.

[0003] At present, guardrail cleaning vehicles are generally used to clean guardrails. During the operation of existing guardrail cleaning vehicles, the water spraying mechanism continuously sprays water to the guardrail, and there is a large gap between the vertical bars on the guardrail, and the width of the gap is much larger than the width of the vertical bar, resulting in serious waste of water resources.
