Artifacts in the snow: blowing snow, tanks, drones, what's the strength?
Recently, cold air has been active in China, and the Meteorological Observatory has issued an orange warning for cold waves, and many places will face strong convection, strong winds, and freezing weather with low temperature rain and snow. In order to cope with extreme weather, various regions have launched "snow removal artifacts" to comprehensively guarantee de-icing and snow melting from railways, highways to the air.
On the short** platform, various "artifacts show magical powers" have been highly praised, arousing netizens' curiosity about these snow removal artifacts: "What are the advantages of these artifacts?" ”
Ice and snow cleaning master"Airborne in Hubei, powerful enough to rival a 12-level typhoon On the afternoon of February 20, two aviation turbofan hot snow blowers made a grand debut at the Wuhan South Toll Station of the Beijing-Hong Kong-Macao Expressway.
It was revealed that this equipment, known as the "master of ice and snow cleaning", has an engine derived from a retired aircraft with a maximum thrust of 88 tons, which is equivalent to the power of a Category 12 typhoon, and this is the first time it has been used in highway de-icing and snow work.
The equipment has an operating speed of about 30 kilometers per hour, a snow blowing thickness of about 10 centimeters, a purging width of about 50 meters, and the air flow heat of the spray can reach 100 degrees Celsius, which can quickly blow snow and dry icy roads, so that the highway can quickly resume traffic conditions in bad weather.
It can be said that the highway snow is removed in ice and snow weather"Artifact"。Now, these two"Ice and snow cleaning master"The equipment commissioning and support work has been completed, ready to deal with bad weather at any time, and will be used for a total of 1,250 kilometers of highway snow removal and smooth work in Wuhan and eastern Hubei under the jurisdiction of Hubei Stock Exchange.
In the cold winter, the inspection operation at the bottom of the EMU has become a big problem for the Harbin EMU depot. Due to the small space, there are potential safety hazards and limitations in the personnel drilling under the car for investigation, resulting in the operation time of up to two hours.
In order to solve this problem, the Harbin EMU has introduced an intelligent robot "small tank". This robot integrates advanced control, navigation and acquisition and transmission technology, and is equipped with two sets of infrared and high-definition cameras.
By detecting the temperature at the key positions at the bottom of the EMU, the image information of key parts such as bogie accessories, floor plates and bolts at the bottom of the EMU is collected from all directions and angles, which provides a scientific and accurate technical reference for the emergency fault disposal of the EMU.
When the oil and water temperature of the locomotive is lower than the standard temperature, the system will immediately prompt the warmer to get on the train. The temperature personnel do not need to go to the scene in person, but only need to check the parameters of the locomotive and operate it through remote command.
This intelligent "little tank" brings great convenience to the bottom inspection operation of the EMU and avoids the occurrence of frozen car accidents.
The use of drones and high-pressure water cannons in bad weather In extremely cold weather, both technology and manpower can play a key role. According to reports, drones were used to spread snow melting agents to help vegetable greenhouses and factories melt snow and de-ice during extreme weather in Xiantao City, Hubei Province, and Xinzhou District, Wuhan.
This drone can take off in heavy snow, and can complete a 2,000-square-meter greenhouse operation in about an hour, and the snow will melt in four or five hours after the snow melting agent is sprinkled.
In addition to drones, water cannons in the hands of firefighters also play an important role in winter. In Suqian, Jiangsu Province, heavy snow bent the movable shed, and the on-site workers could not dismantle it.
Firefighters used their high water jet guns to shoot water to wash the snow away, and successfully washed the snow away and cleaned it up. Similarly, in the city of Jingshan in Hubei Province, SWAT team members used riot shields to shovel snow and successfully help vehicles get out of danger and guide people away safely.
Whether it is modern technology or traditional manpower, they are doing their best to minimize the impact of ice and snow weather on public travel, providing strong support for the smooth work of Baotong.
