A fire-fighting device for an elevator

Abstract

A fire fighting device for an elevator comprises a shaft, and is characterized in that the inner wall of the shaft is provided with a slope gradually decreased from bottom to top; a water pipe is arranged on the inner wall of the shaft; the two ends of the water pipe are connected and buried in a water tank below the shaft; the water pipe is sealed by a plurality of water pipe sub-joints; and spraying heads are arranged on the surfaces of the water pipe sub-joints at intervals. The fire fighting device for the elevator has the beneficial effects that temperature can be efficiently adjusted, energy is saved, a fire disaster can be effectively prevented, and the loss caused by the fire disaster is relieved.

Description

technical field [0001] The invention relates to the field of elevator safety equipment, in particular to an elevator fire-fighting device. Background technique [0002] The chimney effect refers to the phenomenon that indoor air rises or falls along a space with a vertical slope, causing the air to strengthen convection. The generation of chimney effect. In buildings and structures (such as water towers) with shared atriums, vertical ventilation (smoke exhaust) ducts, stairwells, etc. that have characteristics similar to chimneys—that is, have unobstructed circulation spaces from bottom to top, air (including smoke) ) Relying on the effect of density difference, it quickly diffuses along the channel or discharges the building. [0003] The elevator shaft of the elevator is a typical building with chimney effect. Elevators are widely used in high-rise buildings. Once a fire breaks out in a high-rise building, the fire is very likely to be spread to the entire building due...

AI Technical Summary

Problems solved by technology

Once a fire breaks out in a high-rise building, the fire is easily spread to the entire building due to the updraft of the chimney effect, causing greater danger.

At the same time, the air temperature adjustment in high-rise buildings requires a large number of air conditioners to adjust the temperature, which will consume a lot of energy.
