Description

Technical Field

[0001] The utility model relates to the technical field of road engineering, in particular to a deicing vehicle based on road surface reflection. Background Art

[0002] In cold regions, winters are long and snowfall is heavy, significantly reducing the friction coefficient of the road surface compared to other seasons. This makes driving and braking difficult, and can easily lead to traffic accidents. Winter snow typically accumulates on the road in three forms: floating snow, accumulated snow, and ice. While floating snow removal technology is relatively mature, due to economic constraints, population density, and urban size in my country, snowfall on urban roads is prone to accumulation, even of ice. Traditional de-icing methods involve using tools like shovels to knock away the ice, which is not only time-consuming and labor-intensive but also causes significant damage to the road surface. Currently, de-icing machines used on the market are primarily designed for wide roads and require heavy machinery like forklifts. These bulky machines are not suitable for de-icing narrow roads.

[0003] For narrow roads such as sidewalks and streets, we have designed a small, flexible, and maneuverable intelligent deicing vehicle based on road reflection. It determines the deicing location based on the different reflectivities of ice, snow, and road surface, and uses a milling cutter to quantitatively remove ice, reducing road damage and solving the deicing problem on small roads in winter.
