Fire escape channel sprinkler isolation device

Abstract

The invention belongs to the technical field of fire-fighting equipment, and in particular is a spray isolation device for a fire-proof escape channel, including a corridor wall, a staircase and a nozzle; the interior of the corridor wall is provided with a staircase; the lower surface of the staircase is far away from the side of the corridor wall A fire-fighting water pipe is fixed at the position; the lower surface of the fire-fighting water pipe is provided with uniformly arranged installation holes; the lower surface of the fire-fighting water pipe is fixedly connected with a connecting block at the position of the installation hole; There are nozzles; the invention effectively realizes the water wall separation of the fire escape passage, avoids the intrusion of flames, and at the same time avoids the long-term and large-area wetting of the clothes of the escaped people, and avoids the large-area clothing getting wet in winter Prevent frostbite of the escaped crowd, and avoid water spraying directly on the face of the escaped crowd, which will affect the line of sight and improve the escape efficiency.

Description

technical field [0001] The invention belongs to the technical field of fire-fighting equipment, in particular to a spray isolation device for a fire-proof escape passage. Background technique [0002] With the development of urbanization, more and more people live in the city. In order to improve the utilization rate of living space, the height of buildings is getting higher and higher, but because of the increase of building height, the safety of buildings The requirements are getting higher and higher. At present, the main means to deal with the waterproofing of high-rise buildings is to install fire-fighting equipment, and use various intelligent sprinkler devices to extinguish fires to ensure the safety of people's property. [0003] According to CN111228673A, an intelligent sprinkler isolation device for fire escape passages in buildings, the invention can quickly spray water through the cooperation of intelligent sprinklers and water shields, and ensure that the spray ...

AI Technical Summary

Problems solved by technology

[0004] However, in the prior art, there are following insufficient problems in the spray isolation of fire escape passages. First, when a fire breaks out, the nozzles inside the fire escape passages start to spray water. , so that the water sprayed through the nozzle can cover as much space as possible to achieve the effects of fire extinguishing and cooling. However, when people escape through the escape channel, the continuous spraying of water will wet the clothes of the survivors in a large area, especially in winter. Survivors who completely wet their clothes will face the threat of freezing; second, continuous spraying will cause a large amount of water to flow down the face of people passing through the escape channel, which will affect people's rapid escape, especially for people wearing glasses. A large amount of water sprayed will seriously hinder the line of sight and affect the escape efficiency. Third, the escape route, especially the ladder escape route, has a relatively narrow space and is easy for flames to enter. Escape, and under the conditions of a lot of smoke, the indicator light is small, it is difficult for people to see the direction of the indication, etc.
