Technical Field

The invention relates to the field of fire-fighting equipment, in particular to a fire-fighting floor tile for fire disasters.

Background

Fire-fighting equipment refers to the equipment that is used for putting out a fire, preventing fires and fire accident, and common fire-fighting equipment has fire extinguisher, fire hydrant and fire sprinkler head in the life, and the fire extinguisher reaches fire control effect through blowout fire extinguishing materials, and fire hydrant and fire sprinkler head are all put out the conflagration through blowout fire-fighting water, and the fire hydrant is used for conflagration on a large scale, and the fire sprinkler head is used for the indoor little ignition point of little space to put out a fire.

Present indoor fire-fighting equipment mainly relies on the fire sprinkler head to carry out the conflagration response and put out a fire, but the fire sprinkler head is all installed on indoor furred ceiling, when putting out a fire, put out a fire through the mode that sprays downwards, can put out fast little ignition, but the fire sprinkler head is when indoor intensity of a fire is great, because the furred ceiling is far away from below fire source, hardly put out it, lead to the fact the intensity of a fire constantly to increase promptly, finally cause large-scale conflagration, and the water flowers of the fire sprinkler head spun far away apart are evaporated fast in the higher department of temperature, promptly can not effectually reach the ignition and put out a fire.

Disclosure of Invention

The invention aims to solve the defects that a fire-fighting spray head is far away from a fire point and cannot be directly sprayed to the fire point to extinguish fire, and part of sprayed water spray is quickly evaporated at high temperature to achieve an effective fire-fighting effect in the prior art, and provides a fire-fighting floor tile.

In order to achieve the purpose, the invention adopts the following technical scheme:

the utility model provides a conflagration fire control ceramic tile, includes the ceramic tile, a plurality of chambers of putting out a fire have been seted up to the symmetry in the ceramic tile, every the intracavity of putting out a fire all slides and inserts and be equipped with the shower nozzle of putting out a fire, every all install the fixing base on the interior diapire in chamber of putting out a fire, every all fixedly in the fixing base inlay and be equipped with the right angle pipe, it is a plurality of the one end that the chamber of putting out a fire was kept away from to the right angle pipe all extends to in the ceramic tile and is connected with the inlet tube jointly, the upper surface of ceramic tile inlays.

Preferably, a pressure cavity is formed in the fire extinguishing nozzle, one end of the right-angle pipe, which is located in the fire extinguishing cavity, is inserted into the pressure cavity, the right-angle pipe is connected with the fire extinguishing nozzle in a sliding manner, a plurality of injection channels are annularly formed in the fire extinguishing nozzle, the lower ends of the injection channels are all communicated with the lower end of the pressure cavity, a plurality of nozzles are annularly arranged on the outer side wall of the fire extinguishing nozzle and are respectively communicated with the injection channels, a sealing ring is fixedly sleeved at one end of the right-angle pipe, which is located in the pressure cavity, and the thickness of the sealing ring is smaller than the distance from the lower end of the injection channel to the bottom;

when water flows into the right-angle pipe, the water flow is pressed into the pressure cavity by the pressure of the fire fighting pipeline, so that the pressure of the space in the pressure cavity above the sealing ring is increased, and because the fire extinguishing nozzle is connected with the right-angle pipe in a sliding way and the right-angle pipe is fixed on the fixed seat, the fire extinguishing nozzle is jacked up by water pressure to move upwards continuously, so that the sealing ring is close to the inner bottom wall of the pressure cavity continuously, when the sealing ring is contacted with the inner bottom wall of the pressure cavity, a plurality of spraying channels are communicated with the space above the sealing ring in the pressure cavity, then the water flow is sprayed to the periphery through a plurality of spraying channels and a plurality of nozzles, and at the moment, the upper end of the fire extinguishing nozzle is pushed out of the fire extinguishing cavity by the pressure of water, and a plurality of nozzles spray to the periphery above the floor tile for fire extinguishing, the fire extinguishing agent is sprayed from the ground floor tiles, so that the fire extinguishing agent is close to a fire point and can be easily sprayed to the fire point, and the fire extinguishing efficiency and the fire extinguishing capacity are improved.

Preferably, the upper surface of the floor tile is provided with a plurality of nozzle holes, the inner walls of the nozzle holes are provided with sealing rubber mats, the side walls of the fire extinguishing nozzles are provided with sealing plates, and the sealing plates are matched with the sealing rubber mats;

after the shower nozzle of putting out a fire by the ejecting chamber of putting out a fire of water pressure, the closing plate replaces the upper end of the shower nozzle of putting out a fire to inlay and establishes downtheholely at the shower nozzle, and it is sealed between closing plate and the shower nozzle hole that makes through sealed cushion, guarantees to put out a fire the shower nozzle when spraying and put out a fire, and the water that falls down and flow on the floor can not flow into the intracavity of putting out a fire, avoids rivers to get into the chamber of putting out a fire and permeates the ceramic tile in.
