Description

Technical Field

[0001] The utility model belongs to the technical field of highway snow prevention, and particularly relates to a rolling snow prevention shed mechanism. Background Technique

[0002] In some regions of our country, winter is long, the temperature is low, and snowfall is relatively large. Most of the local areas are mountainous terrains with sparse population. As the main transportation roads, they often cannot pass normally due to snow accumulation problems after winter. The current conventional snow removal methods at home and abroad are as follows:

[0003] Artificial or mechanical spreading of snow melting agents: By spreading chemical agents on the road surface to lower the melting point of ice and snow, so that the ice and snow melt, and then the accumulated snow and ice are removed. It is a commonly used means of road ice and snow removal internationally. The commonly used snow melting agents at home and abroad are mainly salts and alcohols. Under certain environmental conditions, spreading snow melting agents can effectively remove road ice and snow, improve road safety conditions, and improve road transportation efficiency. The disadvantage of this method is that the snow and ice removal effect of alcohol-based snow melting agents is greatly affected by the environmental temperature, and there is an anti-freezing phenomenon. Once the environmental temperature drops, the melted snow will refreeze into ice again. And if the snowfall is too large, it is very difficult for the snow melting agent itself to dissolve and melt quickly, making the road surface more slippery and the traffic safety more worrying. At the same time, it also leads to a substantial increase in the comprehensive cost. And the vast majority of salt-based snow melting agent products are corrosive, easily corrode and damage the road structure and motor vehicles, and will also cause pollution to the soil, water body and atmosphere, etc., damaging the ecological environment.

[0004] Spreading sand and gravel materials: Spreading sand and gravel materials with a certain particle size, such as sand, stone chips, furnace ash, cinder, and sand-salt mixture, etc., on the ice and snow road surface can improve the friction coefficient of the ice and snow road surface. The existence of sand and gravel makes the freezing strength of the ice and snow layer uneven on the one hand, and on the other hand, the movement of sand and gravel in the ice and snow layer makes the snow not easy to be compacted, achieving the purpose of anti-skid. The disadvantage of this method is that the sand and gravel materials will be left on the road, and it will also affect the road traffic conditions after the snow has receded.

[0005] Various mechanical ice and snow removal methods: The mechanical ice and snow removal methods for expressways at home and abroad can be roughly divided into two categories: mechanical shoveling of ice and snow and mechanical snow blowing. Mechanical shoveling of ice and snow is suitable for large-scale clearing operations before icing when the snow volume is large. Mechanical snow blowing is suitable for the snow accumulation on the road surface with a relatively thin thickness that has not been rolled, and is usually only applicable to the snow removal of a relatively small area that is convenient for management such as airports. The disadvantage of this method is low efficiency, affecting vehicle traffic and driving safety during operation, inconvenient construction and requiring regular maintenance.

[0006] To sum up, the conventional snow removal methods generally have the disadvantages of affecting traffic during construction, high difficulty, low efficiency, short effective cycle, and the risk of causing secondary hazards, etc. Content of the Utility Model
