Extinguishing device for tall building roof

Abstract

The invention discloses an extinguishing device for a tall building roof, mainly comprising a water storage tank (2) arranged a roof plane (1), a firefighting pump (3) communicated with the inside of the water storage tank (2) and a long-arm fire monitor (4) connected with the firefighting pump (3). By using the extinguishing device, the problem that fire extinguishment in a tall building and a super-tall building can be well solved. The extinguishing device has unique function and remarkable advantage of extinguishing fire in the tall building.

Description

Technical field [0001] The invention relates to a fire extinguishing device on the roof of a high-rise building. Background technique [0002] The construction of modern cities is developing rapidly. Commercial and residential high-rise buildings are becoming more and more taller. Fire-fighting of high-rise buildings has repeatedly occurred, and lives and property cannot be guaranteed. Fires in high-rise buildings spread from the inside to the outside and from the bottom to the top, and they are rapidly escalated from small fires in a short period of time (usually 5-20 minutes) to large-scale fires. The fire will continue to burn higher and higher. The control will rise to a large-scale fire, and finally it will be difficult to put out the fire and rescue, and the loss of life and property will be very serious. The two high-rise fires in Shanghai and Shenyang in 2010 are examples. Traditional fire-fighting facilities cannot meet the needs of modern high-rise fire extinguishing. ...

AI Technical Summary

Problems solved by technology

Traditional fire-fighting facilities cannot meet the needs of modern high-rise fire extinguishing. Using a fire truck to extinguish a fire takes time from receiving fire information to arriving at the scene. It takes as fast as 15 minutes and as slow as an hour. After arriving at the scene, there is still a preparation time. During this period of time, the fire has often spread from a small fire to a large fire, and the fire has burned from a low place to a high place, wasting the best time to extinguish the fire, and a small fire has become a catastrophe

The fire extinguishing agent injection height of ordinary combat fire trucks is within 60 meters, while the fire extinguishing agent injection height of high spray vehicles, climbing vehicles, and ladder vehicles does not exceed 80 meters. Now buildings with a height of 100 meters and above can be seen everywhere in cities. What should I do if there is a fire at a high place? Relying on the fire truck to extinguish the fire, the fire extinguishing agent sprayed by it cannot reach these heights. The most important thing is that when the fire truck sprays upwards, 80% of the fire extinguishing agent falls back to the ground before reaching the fire point, and the loss of the fire extinguishing agent is great. At that time, its movement speed is zero, and it has no impact power on the fire, and the fire extinguishing efficiency is greatly reduced. It is difficult to control and extinguish the fire in this high-rise building with more fire engines.

Another situation is that in many fire scenes, due to the influence of roads, greening and adjacent buildings, fire trucks cannot approach the fire scene, and fire cannons cannot play a role. Long-distance water delivery is required to put out fires, which greatly reduces the ability of fire trucks to extinguish fires at high altitudes. The firefighters are very touched, it is difficult to put out fires in high-rise buildings! I really hope that there is an efficient, fast and more powerful fire extinguishing device to put out high-rise fires and save lives and property
