Automatic snow-removing method

Abstract

The invention discloses an automatic snow removing method, comprising the following steps that: the collection of the quantity of heat in real time collection and the supply of part of the quantity of heat in real time: a geothermy collecting pool buried underground is adopted to collect and accumulate the quantity of heat in the soil, a plurality of geothermy collectors buried underground are adopted to collect the quantity of heat in soil and to provide a thermal source for a foundation heat transmission layer paved under the road surface in real time; the storage of the quantity of heat: the quantity of heat collected by the geothermy collecting pool which is processed by a quantity of heat converting and amplifying processing system is stored into a power accumulator connected with the foundation heat transmission layer to spare; the non-real time supply control of the stored quantity of heat: according to a road surface temperature signal detected by a temperature sensor 3, a control system controls the power accumulator, under normal circumstances, the power accumulator is turned off and is turned on when the road surface temperature is lower than 0 DEG C. The snow removing method has simple and convenient implementation procedure, high feasibility and security as well as reliability, wide range of application and good implementation effect, saves energy and protects theenvironment, can effectively solve the problems of completeness and timeliness of the snow removal in winter.

Description

Technical field [0001] The invention relates to a snow removal method, in particular to an automatic snow removal method suitable for roads and airport runways. Background technique [0002] At present, the removal of snow and ice from roads and public facilities in cold areas in winter has always been an old and difficult problem. Because snow affects people’s transportation and travel is very common, the government and relevant departments have to invest a lot of money and energy every year. Solve the impact of ice and snow on safety, especially for deicing and snow removal on airport aprons, runways, highways, bridge decks, etc. Traditional snow removal methods use a combination of artificial removal and natural melting, and mainly include the following methods. [0003] The first method is manual removal. The snow removal tools used are mainly shovels, shovels, brooms, etc. For roads, streets and other places that affect people's traffic, manual snow removal is required, which...

AI Technical Summary

Problems solved by technology

Most of the snow-covered city streets, courtyards, public squares, etc. are still cleaned by sanitation personnel or the masses with artificial auxiliary machinery. The labor intensity is high, the work efficiency is low, the cost is high, and the snow removal is not thorough, and the residual snow is easy to freeze at night; sometimes the snow cannot be removed in time, and it will also affect the traffic

[0004] The second method is the mechanical snow removal method: the snow removal machine is used to clean the snow while it is falling and the cleaning is more thorough, which is widely used in important roads, airports, bridge decks, etc. When the amount of snow is large, the timeliness of snow removal is not high, and it is not possible to remove snow in a large area. The cost of remote operation is high, and it can remove snow but not ice.

Most of the existing snow removal machines are bulldozer-type structures, which are difficult to remove the snow that has been pressed by vehicles or the snow that people have stepped on, especially on ice and snow roads, and the snow removal effect is poor.

Generally, the snow removal machine can only remove the snow layer below 50mm. Although it can clean the above-mentioned uncompacted snow and improve the snow removal effect, but because it cannot break the ice, it is helpless to the ice and snow road.

If the ice and snow road cannot be cleaned up in time, it will bring many difficulties to motor vehicles and pedestrians, and even cause urban traffic jams and paralysis of transportation.

[0005] The third is the chemical snow removal method: using low-freezing chemical substances and ice and snow to melt snow to achieve the purpose of snow removal. Its labor intensity is relatively low and snow and ice removal can be carried out at the same time. It is mainly used for bridge decks, runways, airport aprons, etc. ; but its high input cost, slow snow melting speed, low real-time performance and incomplete snow removal will also cause a certain degree of corrosion on the road surface, and it is also easy to cause environmental pollution

[0006] The fourth is the artificial heating method, which uses artificial heating methods such as fuel and electric heating to remove snow accumulation, and snow removal and ice removal can be carried out at the same time; but the investment cost is huge and cannot be popularized

Because the air density is too small, the airflow blown from the nozzle has a large diffusion angle, and a large part of the high-speed airflow is blown to the atmosphere, and the energy utilization rate is very low.
