According to incomplete statistics, there are about 75,000 fires in China each year, about 1086 people are killed, 983 are injured, and direct property losses amount to 480 million yuan. However, these four figures account for 32.5% and 43.9 of the total annual fires respectively. %, 27% and 26.9%. Looking at the high frequency of fire incidents, fire engines played an irreplaceable role in combating this natural disaster.
Fire trucks, also known as fire trucks, play a very important role in fire extinguishers by lifting high jets.
The fire truck itself is equipped with a complete water supply system, mainly using hydraulic rotation so that there is more power to spray at high altitude. The high-ejection fire-fighting vehicle is provided with a remote-controlled spray gun. The remote-control spray gun is located in the middle of the upper arm's top diverging pipe. The hollow shaft serves as a fulcrum, mainly relying on the rotation of the hydraulic motor to achieve pitch within a certain range of angles, and the spray gun will be within a certain angle. Swinging movements left and right can effectively control large areas of fire and reduce the economic losses caused by fire.
In addition to being used for firefighting or other emergencies and disaster relief purposes, fire sprinklers can also be used as high-altitude water supply in hot summer seasons such as the end of the year 009 and 2010 droughts in Yunnan, Guizhou, Guangxi, Chongqing and Sichuan. The reservoirs of the Gaoshishao Green Pond in Shilin County of Kunming City all bottomed out, and most areas in Yunnan, including western Guizhou and northwestern Guangxi, have reached very large drought levels, among which drought conditions in Yunnan are particularly serious.
In the same year, the area of ​​farmland affected by drought reached 67.87 million mu, and 15.01 million people and 9.23 million large livestock were in a state of drought and drinking water. It has been very difficult to solve the drought problem at the time of repairing trenches. Fire sprinklers have played a major role in relieving the disaster.
In hot summers and cold winters, we always see the trails of sprinklers. In summer, the weather is too hot. The fire sprinkler has played a very effective cooling effect by spraying water on the road. It also played a good role in the watering of the garden construction. Prevention of natural fires caused by high temperatures; cold winter is also a high incidence of fire, the humidity in the air in winter is relatively low, sprinklers to the surface of the water to play a very good role in air purification.
Fire sprinklers play an irreplaceable role in our lives. Once a fire is in danger, the first thing that comes to mind is to dial 119 to contact a fire sprinkler for our safety escort, so the fire sprinkler is not only from its containment of natural disasters. And the settlement of dangerous situations in daily life has played a great role.
