Description

Fire extinguishing floor

Technical Field

The invention relates to the technical field of floors, in particular to a fire extinguishing floor.

Background

Floor, i.e. the surface layer of the floor or floor of a house. Most of the existing floors are made of combustible materials, such as wood boards and the like. Once a fire occurs indoors, the floor is undoubtedly the fierce of the fire, causing greater property loss of residents, and the floor is made of fireproof materials in order to prevent the spread of the fire, but the effect is general. To solve the above problems, we propose a floor that serves to extinguish a fire when encountering a fire.

Disclosure of Invention

The invention aims to solve the problems in the background art and provides a fire extinguishing floor.

In order to achieve the purpose, the invention adopts the following technical scheme: the fire extinguishing floor comprises a floor body, wherein a cavity is formed in the floor body, a partition plate is fixedly connected with the inner wall of the cavity in a sealing mode, the cavity is divided into a liquid storage cavity and a reaction cavity from top to bottom by the partition plate, HCl solution is contained in the liquid storage cavity, CaCO is placed in the reaction cavity₃The inner top wall of the liquid storage cavity is provided with a plurality of temperature sensing triggering devices at equal intervals from left to right; the temperature sensing trigger device comprises a top groove formed in the top wall of the liquid storage cavity, an annular limiting groove is formed in the inner wall of the top groove, a limiting plate is vertically connected in the limiting groove in a sealing and sliding mode, the limiting groove, the top groove and the limiting plate form an expansion cavity together, expansion liquid is filled in the expansion cavity, the lower end of the limiting plate is fixedly connected with a needle rod, a through hole is formed in the corresponding position of the needle rod through the partition plate, and a sealing film is connected to the through hole in a sealing mode; the floor is internal and evenly set up the jet-propelled passageway that is L type and one end and reaction chamber intercommunication in the week side of cavity, the diffusion hole that loudspeaker form and communicate with the external world is seted up to the one end that the reaction chamber was kept away from to the jet-propelled passageway, and the wide face end in diffusion hole up, the narrow face end down.

In the fire extinguishing floor, the inner wall of the diffusion hole is connected with the sealing plug in a sealing manner, and the upper end face of the sealing plug is flush with the upper end face of the floor body.

In the fire extinguishing floor, the expansion liquid is water.

In the fire extinguishing floor, a warning whistle 16 is arranged in the air injection channel 13.

Compared with the prior art, the fire-extinguishing floor has the advantages that:

1. once a fire occurs, the heat conducting part at the upper end of the floor body conducts heat to the expansion liquid, the volume of the expansion liquid is increased and drives the needle rod to descend to puncture the sealThe HCl solution flows into the reaction cavity through the through hole automatically to generate a large amount of CO₂The fire extinguishing agent is sprayed out through the air spraying channel and the diffusion hole to prop open the sealing plug, so that oxygen is isolated from combustible materials, and the fire extinguishing effect is achieved, thereby restraining the spread of fire and protecting the property of residents;

2. CO flowing through the gas injection channel₂The whistle can be sounded to remind residents to fight or retreat in time, and casualties caused by untimely fire finding or retreat are avoided.

fig. 2 is a schematic structural view of an embodiment 2 of the fire extinguishing floor provided by the invention.

In the figure: 1 floor body, 2 clapboards, 3 liquid storage cavities, 4 reaction cavities and 5CaCO₃The device comprises particles, 6HCl solution, 7 sealing films, 8 top grooves, 9 limiting grooves, 10 limiting plates, 11 expanding liquid, 12 needle rods, 13 air injection channels, 14 diffusion holes, 15 sealing plugs and 16 warning whistle.

Detailed Description

The following examples are for illustrative purposes only and are not intended to limit the scope of the present invention.

Example 1

Referring to fig. 1, a fire extinguishing floor comprises a floor body 1, a cavity is formed in the floor body 1, a partition plate 2 is fixedly connected with the inner wall of the cavity in a sealing mode, the cavity is divided into a liquid storage cavity 3 and a reaction cavity 4 by the partition plate 2 from top to bottom, HCl solution 6 is contained in the liquid storage cavity 3, CaCO is contained in the reaction cavity 4₃The particles 5 and the inner top wall of the liquid storage cavity 3 are provided with a plurality of temperature sensing triggering devices at equal intervals from left to right; specifically, temperature sensing trigger device is including seting up the top groove 8 at stock solution intracavity 3 interior roof, annular spacing groove 9 has been seted up to the inner wall of top groove 8, the vertical limiting plate 10 that has to sealed sliding connection in spacing groove 9, top groove 8 and limiting plate 10 constitute the inflation chamber jointly, and the inflation intracavity is filled there is inflation liquid 11, inflation liquid 11 is water, it is comparatively common, the lower extreme fixedly connected with needle bar 12 of limiting plate 10, baffle 2 has seted up on the corresponding position of needle bar 12 and has run through the mouth, and the sealing connection has a membrane 7 on the run through mouth, play isolated from havingThe HCl solution 6 acts on the reaction chamber 4; the air injection channel 13 which is L-shaped and one end of which is communicated with the reaction cavity 4 is evenly arranged on the periphery of the cavity in the floor body 1, the diffusion hole 14 which is trumpet-shaped and is communicated with the outside is arranged at one end of the air injection channel 13 far away from the reaction cavity 4, the wide face end of the diffusion hole 14 faces upwards, and the narrow face end faces downwards, so that the air injection (fire extinguishing) range is enlarged.

The inner wall of the diffusion hole 14 is connected with a sealing plug 15 in a sealing mode, the upper end face of the sealing plug 15 is flush with the upper end face of the floor body 1, and the diffusion hole 14, the air injection channel 13 and the reaction chamber 4 are sealed.

It should be noted that, under normal conditions, the upper end surface of the sealing plug 15 is flush with the upper end surface of the floor body 1, and the connecting channel 13, the diffusion hole 14 and the reaction chamber 4 are in a sealed state, so as to prevent the CaCO from being soaked by the moisture in the air₃Particles 5; the part of the floor body 1 right above the cavity and at the corresponding position of the top groove 8 is made of heat conducting materials, so that the heat can be better conducted into the expansion liquid 11; the limiting plate 10 is positioned in the middle of the limiting groove 9 under the hydraulic action.

Once a fire occurs, the heat conducting part at the upper end of the floor body 1 conducts heat to the expansion liquid 11, the expansion liquid 11 increases in volume and drives the needle rod 12 to descend, the sealing membrane 7 is punctured, the HCl solution 6 automatically flows into the reaction cavity 4 through the through hole, and CaCO according to the chemical reaction formula₃+2HCl＝＝CaCl₂+H₂O+CO₂×) producing large amounts of CO₂The fire extinguishing agent is sprayed out through the air spraying channel 13 and the diffusion hole 14 to prop open the sealing plug 15, so that oxygen is isolated from combustible materials, and the fire extinguishing effect is achieved, thereby restraining the spread of fire and protecting the property of residents.
