Description

A support assembly for a high-pressure fire monitor

technical field

The utility model belongs to the technical field of fire protection, in particular to a support assembly for a high-pressure fire monitor.

Background technique

In today's society, with the advancement of urbanization, the speed of high-rise construction is accelerating, but the development of fire-fighting equipment for high-rise buildings is relatively lagging behind. At the same time, with the rapid development of the chemical industry, various types of fire-fighting incidents that are prone to explosion and are not suitable for humans to deal with are on the rise. . This year, the number of firefighters and soldiers has been increasing due to lagging firefighting equipment in high-rise buildings and dealing with explosive cases at close range during firefighting. This problem in firefighting has not been resolved. The current fire-fighting methods mostly use aerial ladder fire trucks to solve the problem of high-rise fire protection. The effective working height of common aerial ladder fire trucks is 30-50 meters, and the height can reach 60-70 meters. However, due to the large size of the fire truck, it is difficult to pass through the narrow streets due to the limited speed of the street when it is dispatched for firefighting.

Once a fire breaks out in a high-rise building, a notable feature is the "chimney effect", that is, the hot air formed by the fire on the ground floor, because of the low density, can flow online through the elevator slot or stair passage, just like a huge chimney. The air flow makes the high-heat gas continuously accumulate at the top of the aisle. As a result, the fire passes through the convection of this air to create another fire field on the top floor of the building. And as the hot air was expelled, fresh air continued to be sucked in from the bottom process, causing the fire to intensify further. This kind of fire mostly spreads along the elevator shaft or corridor passage. Firefighters cannot extinguish the fire from the outside like dealing with general building fires. However, in these narrow areas, fire extinguishing equipment cannot work effectively. Once the fire spreads to high-rise floors, firefighters cannot carry fire extinguishing equipment to fight the fire, which brings great difficulties to the rescue work.

Therefore, high-pressure fire-fighting water cannons have become the main fire-fighting tools.
