Spraying equipment capable of moving along elevator shaft and inhibiting fire chimney effect

Abstract

The spraying equipment moving along the elevator shaft and inhibiting the fire chimney effect comprises the elevator shaft, a first steel cable, a blocking air bag, a spraying head, a power chamber and a second steel cable, first sliding rails are fixedly installed on the two sides of the elevator shaft, and a movable platform and a lift car are sequentially installed on the first sliding rails in a sliding mode from top to bottom; one end of each first steel cable is fixedly connected with the top of the lift car. The spraying equipment capable of moving along the elevator shaft and inhibiting the fire chimney effect is provided with a spraying head and a spraying pipe, after the movable platform moves to a designated position along the elevator shaft, external water supply equipment supplies water to the spraying pipe through a water conveying pipe, and then water in the spraying pipe is sprayed into the elevator shaft through the spraying head; the air temperature in the elevator shaft is reduced, the possibility that the chimney effect is generated in the elevator shaft is further restrained, the fire spreading speed is reduced, time is bought for escape of people in a high-rise building on fire, and using is safer.

Description

technical field [0001] The invention relates to the technical field of spray equipment, in particular to a spray equipment that moves along an elevator shaft and suppresses fire chimney effects. Background technique [0002] With the development and progress of society, more and more high-rise buildings are planned and constructed in cities, and the problem of fire in high-rise buildings has become more and more prominent. High-rise fires are affected by the chimney effect, and their fires can easily spread, leaving time for people in high-rise buildings to escape. It is short, making it difficult for people in high-rise buildings to escape. Once a high-rise fire occurs, it is very easy to cause major disasters, especially the elevator shaft, whose shape is straight, and the elevator shaft is connected to all floors in the high-rise building at the same time, and the elevator door is difficult to be completely closed. , causing the fire to spread easily through the elevator ...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a kind of sprinkler equipment that moves along the elevator shaft and suppresses the fire chimney effect, so as to solve the problem that the fire in the high-rise building proposed in the above-mentioned background technology is easy to spread rapidly due to the chimney effect of the elevator shaft, causing fire in the high-rise building. The escape time of personnel is short, and the car is prone to stay in the fire area in the event of a fire and power failure, making it difficult for the occupants in the car to escape
