Description

Technical Field

[0001] The utility model relates to the technical field of aerosol fire extinguishing, in particular to environmentally friendly hot aerosol fire extinguishing equipment. Background Art

[0002] Aerosol fire extinguishing devices can be divided into hot aerosol and cold aerosol according to the way aerosol is generated. Hot aerosol extinguishes fire based on the principles of negative catalysis and destruction of the combustion reaction chain. Hot aerosol fire extinguishing equipment belongs to a full flooding system. It gradually extinguishes the fire by full flooding while controlling the fire source, so that people have enough time to evacuate. It is suitable for unmanned, relatively closed and small places such as substations, generator rooms, cable mezzanines, cable wells and cable trenches. In actual use, it has the advantages of stable structure, safe use and good effect.

[0003] The prior art discloses a hot aerosol fire extinguishing device with a publication number of CN219614788U, comprising a shell, a top cover, an eruption hole, a bottom cover, an eruption area, a porous disk, a cooling area, a cooling ball, a powder column area, an aerosol powder column, a triggering agent, a temperature sensing detector, a stainless steel mesh, a porous sheet, a positioning ring, a positioning spring, a first paper core, a second paper core and rock wool. The temperature sensing detector ignites the triggering agent after receiving a heat-sensitive source or an open flame signal. The triggering agent triggers the ignition to start the aerosol powder column. The aerosol fire extinguishing agent burns to produce high-pressure gas and aerosol particles. The high-pressure gas carries the aerosol particles to diffuse and is cooled by the cooling ball. The cooling ball occupies a large amount of space in the cooling area, so that there is only limited gas space in the cooling area, thereby maintaining continuous high pressure in the shell, improving the combustion effect of the aerosol fire extinguishing agent, producing a sufficient amount of aerosol particles, and spraying them from the top cover under high pressure to achieve rapid fire extinguishing.

[0004] In the above utility model, when the aerosol spray angle needs to be adjusted, the operator needs to hold the shell to adjust it, but there is no connection structure. When the operator accidentally loses his grip on the shell, the shell will be separated from the operator's hand due to gravity. At this time, the aerosol sprayed from the shell cannot be sprayed toward the fire source, reducing the practicality of the utility model.

[0005] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

[0037] Working principle:

[0038] When actually using the environmentally friendly aerosol fire extinguishing device, the operator passes four fingers through four groups of annular airbags 21 respectively, and then holds the outer shell 1 with the hand. During this process, the elastic airbag 17 will be squeezed, and the gas inside the elastic airbag 17 will enter the inside of the gas storage tank 14 through the connecting pipe 18. The gas inside the gas storage tank 14 enters the inside of the four groups of annular airbags 21 through four groups of communicating pipes 22, and the four groups of annular airbags 21 will gradually bulge. When the inner walls of the four groups of annular airbags 21 are in close contact with the four fingers of the operator, the closing control valve 19 is closed. At this time, the outer shell 1 will not break away from the operator's hand. When the temperature sensor 26 detects a temperature change, it will send a signal to the controller. The controller ignites the trigger agent 11 through the electric ignition cable. The trigger agent 11 starts the aerosol medicine column 4. The aerosol fire extinguishing agent burns to generate high-pressure gas and aerosol particles. The high-pressure gas carries the aerosol particles and diffuses. After being cooled by multiple groups of cooling balls 8, sufficient aerosol particles are generated and sprayed out from the upper cover 9 under high pressure to achieve rapid fire extinguishing. The positioning ring 6 will guide the aerosol particles, and the positioning spring 7 abuts against the porous plate 3 to buffer and prevent the positioning ring 6 from shifting. The aerosol can be eliminated by precipitation or the collision and aggregation between small particles, which is environmentally friendly and harmless. Through the set gas storage tank 14 and elastic airbag 17, there is a connection structure, which can prevent the outer shell 1 from accidentally breaking away from the operator's hand and improve the practicality of the environmentally friendly aerosol fire extinguishing device. At the same time, before actually using the environmentally friendly aerosol fire extinguishing device, four groups of baffle plates 25 will cover multiple groups of spraying holes 16 to prevent external impurities from blocking the multiple groups of spraying holes 16, thereby affecting the spraying of aerosol particles inside the outer shell 1. When it is necessary to use the environmentally friendly aerosol fire extinguishing device, the installation screw 23 and the installation nut 24 are threaded together. The operator rotates the installation nut 24 counterclockwise by hand. When the installation nut 24 is separated from the rotating orifice plate 15, the operator rotates the rotating orifice plate 15 by hand. The rotating rotating orifice plate 15 can drive the four groups of baffle plates 25 to move. When the four groups of baffle plates 25 are misaligned with the multiple groups of spraying holes 16, the operator rotates the installation nut 24 clockwise by hand. When the installation nut 24 is in close contact with the rotating orifice plate 15, the four groups of baffle plates 25 will not cover the multiple groups of spraying holes 16, and the aerosol particles can be discharged through the multiple groups of spraying holes 16. Through the set rotating orifice plate 15, it can prevent external impurities from blocking the sealed spraying holes 16 and bring guarantee for the use of the environmentally friendly aerosol fire extinguishing device.
