Wind-water linkage embedded fire-fighting spraying smoke exhaust system

Abstract

The invention discloses a wind-water linkage embedded fire-fighting spraying smoke exhaust system. The wind-water linkage embedded fire-fighting spraying smoke exhaust system comprises a smoke exhaustpipe and a fire-fighting water pipe which are buried in a wall body, wherein the fire-fighting water pipe is located in the smoke exhaust pipe and is mounted in the middle; a spraying smoke exhaust device is mounted on the smoke exhaust pipe and the fire-fighting water pipe in a common thread sealing manner; a water inlet channel and a water drainage channel are arranged at the upper and lower ends of the spraying smoke exhaust device in an inward concave manner respectively; a rotary sleeve is mounted between the water inlet channel and the water drainage channel in a common sealing and rotary manner; and a sealing ring is mounted in the water drainage channel. According to the wind-water linkage embedded fire-fighting spraying smoke exhaust system, the fire-fighting water pipe and the smoke exhaust pipe are mounted in a mother-child manner so that the spraying smoke exhaust device can be used for spraying and extinguishing fire and exhausting smoke and defogging at the same time; the water inlet channel and the water drainage channel are connected through the rotary sleeve so that smoke exhaust blades can rapidly rotate to exhaust the smoke and defog; a rubber plug is automatically opened and closed according to the temperature through a temperature sensing bag and a hydraulic supporting column, so that the functions of spraying a fire disaster and stopping when the fire isextinguished are realized.

Description

technical field [0001] The invention relates to the field of fire-fighting equipment, in particular to a wind-water linkage embedded fire-fighting sprinkler and smoke exhaust system. Background technique [0002] Public places such as office buildings and office buildings pay more attention to fire, so multiple fire hydrants and fire sprinklers are installed on each floor. These fire-fighting equipment can quickly and effectively extinguish the initial fire, avoiding the growth of the fire, Fire sprinklers are the most used fire fighting equipment. [0003] The existing fire-fighting sprinkler system senses the temperature of the glass sphere and opens the sprinkler to spray water to extinguish the fire. The broken glass sphere cannot be restored, so the water cannot be stopped in time, and the water cannot be automatically stopped after the small fire is extinguished, which is a waste of water resources. , and the smoke in the fire is more harmful to people, and a large am...
