In the past few days, there has been a wide range of "freezing rain" and snow in some provinces and cities in the south, resulting in high-speed rail delays and a number of high-speed vehicles being trapped, which lasted for three days and three nights, mainly due to the icing of high-speed rail transmission lines and the icing and snow on some sections of the high-speed section.
Now the departments at all levels in the jurisdiction of the road section of the emergency rescue, the Ministry of Railways is dispatched to the "Taiye-level" diesel traction locomotive to drag the motor car to run, but the highway does not have this kind of "ancient artifact", although many places to mobilize tens of thousands of party members and masses on the road to remove ice and snow, but the progress is slow, this extreme weather to the local transportation authorities put forward new challenges.
The traditional road snow removal is nothing more than a large snow plow, but this kind of machinery is OK on the non-icy road surface, once the road surface is frozen, the snow plow itself skids, not to mention, the shovel is only floating snow, the ice below can not be removed, and the road still does not have the conditions for opening to traffic, especially the highway, even more so.
Therefore, in response to the problem of rapid snow removal on traffic roads, some explorations have been carried out at home and abroad. In recent years, there have been many large-scale freezing rain phenomena in China, Jiangxi and Hunan in 2008 have suffered from large-scale freezing rain, resulting in icy roads, traffic jams in the Hunan section of the Beijing-Zhuhai Expressway, the main artery of the north and south, some cables and power towers have been crushed and collapsed, and some cities have cut off water and electricity.
In 2018, Guangdong Erguang Expressway is located in the mountainous area of northwest Guangdong, bordering Hunan, with a special geographical location, and also encountered ice and snow disasters.
It is said that the earliest method came up with in Russia, simple and rude, very strong violent aesthetic style, because of the low cost and simple and easy, it was immediately introduced into the country by some units in China for imitation manufacturing, and finally developed a variety of similar snow removal equipment, used in airport security, special road section maintenance.
This kind of super snow blowing car, basically using the original old fighter eliminated from the aero engine to develop, because the power engine of the fighter is strong, so this kind of snow blowing car sprays out of the heat up to 800 degrees Celsius, with a large exhaust volume, ultra-low fuel consumption, long life, high reliability characteristics, can blow away about 1 square meter of snow in an instant, 10 seconds to dry the icy road, so that the airport, the highway quickly reach the traffic conditions, is the snow removal "artifact" on the ice and snow road. It should be the fastest snow removal, the best ice blowing effect, and the most reliable thermal blowing snow removal machine at present.
At present, several domestic snowblowers are equipped with domestic fighter engines, there are turbojet 5, turbojet 6, turbojet 7, these engines previously belonged to J-5, Qiang-5, J-6, J-7, J-8 standard aviation engine, now most of these models have been eliminated by the Air Force, the removed engine is directly installed on the snowblower, simple modification can be used on the road, the snow removal effect is very obvious.
The de-icing and snow removal of some high-speed sections in Hubei and Hunan, the relevant departments have urgently dispatched this "super snow blowing vehicle" in place and started to operate, but the road surface is too long, and it is difficult to clear a large area of the road surface in a short period of time with a small number of equipped machinery, so some sections of the road are still congested, but now the local party members and some garrisons are on the road to de-ice and shovel snow, and the main road should soon be completed in these days, and the returnees trapped in the highway will be safely brought back to their homes.
Although this aero engine has large fuel consumption and high oil requirements, but after all, it is a short-term artifact in response to extreme weather, and the cost-effectiveness ratio is quite cost-effective. If the subsequent improvement is made to eliminate the use of aviation kerosene, the cost will be lower.
China has a kind of ability, that is, a strong industrial manufacturing and the first chain cost dilution capacity, once it can be manufactured in batches, the domestic ability to quickly make a certain product into a "cabbage price", the future will not be complete The world is using this "super snow blower" is not impossible to come from China.
