Description

Fire extinguishing device for high-rise building

Technical Field

The utility model relates to the technical field of high-rise building fire fighting equipment, in particular to a high-rise building fire extinguishing device.

Background

As the population of cities and towns in China is increasing day by day and land resources are very precious, more and more high-rise buildings are pulled out of the ground along with the rapid development of economy. Although these high-rise buildings are beautiful and have strong practicability, once a fire disaster happens at a higher position of the high-rise building, the fire disaster can seriously threaten the life and property safety of the masses. In order to prevent high-rise building fire, high-rise building fire extinguishing devices are often arranged in the high-rise building. The patent document with the prior art publication number of CN212998100U provides a fire extinguishing apparatus for high-rise buildings, which can push the whole fire extinguishing apparatus by a pushing handle, is convenient to move, can control the spraying of the fire extinguishing apparatus by an electromagnetic switch, can adjust the spraying angle at will by the cooperation of a handle and a rotating support device at the bottom, and can be controlled without people contacting the fire extinguishing apparatus. Although the device has more beneficial effects, the following problems still exist: when a fire disaster occurs in a high-rise building, it is often difficult for ordinary people to accurately judge the fire behavior. However, when the fire extinguishing device is used for extinguishing a high-rise fire, a user needs to control the spray head through the control lever all the time. Once the fire is not effectively controlled, the precious escape time is likely to be delayed, so that the user cannot escape smoothly. In view of this, we propose a fire extinguishing apparatus for high-rise buildings.
