Fire-fighting extinguishment system

Abstract

The invention discloses a fire-fighting extinguishment system. The initial state is that a deflector makes clinging contact with a ceiling. In the case of fire, a glass ball is broken due to heating,the sealing inclined surface of a sealing slide block is stressed by the downward flowing pressure of water flow, the pressure generates a thrust force facing the direction of a through hole on the sealing inclined surface, and then pushes the sealing slide block to slide backwards by virtue of the cooperation of a slide guide part and a guide through hole, until a clamping step is abutted againstthe upper edge of the through hole; and at this moment, a sealing part retreats into the guide through channel, and the sealing part does not seal a water spray channel any more; the water flow impacts the deflector through the water spray channel, and the downward spray pressure of the water flow pushes the deflector to drive a single vertical leg body and a support ring to overcome the pull force of a pull spring and pull the pull spring to stretch downwards, so that the deflector slides downwards to reach a normal working height; and the water flow is sprayed to the surrounding through thedeflector, until finally fire is extinguished. After the fire is extinguished, a spray head main body stops water spray, and the water flow loses the downward impact pressure on the deflector, so that the fire-fighting extinguishment system is recovered to the initial state.

Description

technical field [0001] The invention relates to the field of fire-fighting equipment, in particular to a fire-fighting and fire-extinguishing system with a telescopic function. Background technique [0002] In the fire automatic fire extinguishing system, the fire sprinkler is one of the patron saints of people's life and property. It is responsible for the two missions of monitoring the fire and implementing fire fighting. It is mainly used in light and medium dangerous places and commercial places, such as banks and hotels. , shopping centers, etc. Each fire sprinkler has a specific protection area. When a fire occurs, water is sprinkled through the splash plate of the fire sprinkler to extinguish the fire, and the fire water is evenly sprinkled through the fire sprinkler to control the fire in the area. The structure of the fire sprinkler is as Chinese utility model patent CN201420453835.8 discloses a new type of glass ball sprinkler, including a support frame, a glass b...

AI Technical Summary

Problems solved by technology

The structure of this utility model is roughly similar to other fire sprinklers on the market. When in use, the fire sprinklers are installed on the water supply pipes, and 80-100% of the total water can be sprayed to the ground in a distributed manner. During the process, the fire-fighting effect cannot be effectively exerted, and the splash plate and the connecting frame where the fire sprinkler is exposed on the ceiling are prone to horizontal collisions, resulting in damage to the splash plate and the connecting frame, and affecting the appearance
