Regardless of whether the rainstorm comes or not, you can read this article first, and then, the critical moment can save your life!

Fruit shell colleagues have discussed in the group how to go to work tomorrow, what slippers to wear, and the shell store next door even took the opportunity to sell umbrellas… [/p > < p > in the rainstorm, where should pedestrians avoid is safer? What should we pay attention to when driving through the water during heavy rain? How can we not get trapped on the road because of the water coming into the vehicle? Do you know that it can threaten life if you wade in water and don’t wash your feet? Generally speaking, the meteorological warning signals of various regions can be divided into two types: warning signal and warning signal. The former is to convey “wolf is coming”, and the latter is “wolf is coming”. “White” and “blue” belong to the warning signal of “wolf coming”. Although the sky looks calm, people should know that in an hour, it may be a big storm! “< p > < p > higher-level signals, such as” yellow “,” orange “and” red “, are generally issued when bad weather has affected the local and may continue or even become worse. If not necessary, people should stay in the safe place as far as possible until the signal is released and be prepared for accidents. It is important to stress that when you see the lowest level of signal being released, it is important to remember that severe weather may affect the local area in the next 12 hours. As the rainstorm cloud cluster can be observed on local radar at most 2-3 hours in advance, it must not have the idea of “more time” and be careful as only 1-2 hours of spare time. It is important to consider the plan of hiking, outing or going to low-lying areas carefully, and pay attention to the changes of the sky at any time. It is important not to take a light mind when the weather is fine, unless the meteorological department cancels the warning signal later. Driving should avoid wading as much as possible, but sometimes we have to face the situation that must wade. What kind of situation will the vehicle shut down? In principle, the exhaust pipe immersed in water will not cause flameout, but if there is a reverse irrigation, the consequences are serious. The inlet of the intake pipe must not be filled with water, and the water will shut down. Once the engine is stalled, it must not be started again. Because it is possible to enter the cylinder at this time, water can not be compressed relative to air. The compression ratio of gasoline engine is about 10 times, and that of diesel engine is about 18 times. When the cylinder is compressed, the water will bend the crankshaft, valve and other parts, which will cause great damage to the engine. Modern vehicles have very complex electrical systems, which can cause problems if the sealing is not good. The transmission axle and other parts are not absolutely sealed, and water may be mixed into the lubricating oil. Dry clutch will slip, the grease on axle will be diluted, friction of brake pad will be reduced, and fan blade of cooling fan may be damaged due to water injection If the vehicle is wading, it is better to prepare carefully before each wading and carry out necessary maintenance after wading. If the Wade depth exceeds the chassis but does not exceed the air inlet, it is better to conduct a check and maintenance after wading. With the rain aggravating, rumors will also arise in the circle of friends, microblogs and wechat groups. All kinds of shocking pictures or videos of subway leakage, road collapse and landslides spread. But then, most of these rumors were confirmed as false news, some were disaster situations in other areas, some were old pictures “Zhang guanlidai”, some even synthesized: < p > during the disaster prevention period, no unconfirmed information must be spread. Rumors and blind movements will not only bring direct life or property risks to themselves and related personnel, but also disrupt the execution order of the whole disaster prevention system, weaken the credibility of the disaster prevention system, and increase unnecessary costs and even irreparable costs for disaster relief workers!
