[0032] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.
[0033] In the present invention, unless otherwise stated, directional words such as "inside, outside, up, down, top, bottom" contained in the terms merely represent the orientation of the terms in normal usage, or are common names understood by those skilled in the art, and should not be regarded as limitations on the terms.
[0034] See also Figure 1 The present invention provides a fire-sensing automatic explosion fire extinguishing device, which comprises a fixed rail 1 laid on the roof of a house and a plurality of smoke alarm devices 2 evenly arranged on the fixed rail 1, the fixed rail 1 is also connected with a slidable sliding assembly 3, the sliding assembly 3 is detachably mounted with a fire extinguishing assembly 4, the fire extinguishing assembly 4 is filled with an explosive fire extinguishing bomb 444 and is connected to a storage tank 5 so that the storage tank 5 can replenish the explosive fire extinguishing bomb 444 in the fire extinguishing assembly 4; wherein,
[0035] A feedback control system is installed on the smoke alarm device 2, and the feedback control system is configured to be able to feedback the smoke area and control the sliding component 3 to slide to the smoke area;
[0036] The fire extinguishing assembly 4 is configured to locate the flame area and launch an explosive fire extinguishing bomb 444 toward the flame.
[0037] Through the above technical scheme, a fixed rail 1 is laid on the top of the house and a plurality of smoke alarm devices 2 are arranged on the fixed rail 1. A slidable sliding assembly 3 is also connected to the fixed rail 1, and a fire extinguishing assembly 4 is detachably installed on the sliding assembly 3. At the same time, a feedback control system is installed on the smoke alarm device 2, and the feedback control system feeds back the smoke area, and then controls the sliding assembly 3 to slide to the smoke area, and an explosive fire extinguishing bomb 444 is filled in the fire extinguishing assembly 4. After the explosive fire extinguishing bomb 444 is activated, it can be dispersed toward the positioned flame area to extinguish the fire accurately and reliably. In addition, the fire extinguishing assembly 4 is also connected to the storage tank 5. By replenishing the explosive fire extinguishing bomb 444 in the fire extinguishing assembly 4 through the storage tank 5, a continuous fire extinguishing operation can be achieved. In addition, the explosive fire extinguishing bomb 444 in the above-mentioned fire extinguishing assembly 4 can be filled with different fire extinguishing agents according to different fire extinguishing needs, which can further improve the fire extinguishing efficiency.
[0038] Specifically, in this embodiment, in order to optimize the structure of the fire extinguishing assembly 4 and facilitate quick, convenient and accurate fire extinguishing operations, preferably, the fire extinguishing assembly 4 includes a temperature measuring shell 41 installed below the sliding assembly 3, an infrared thermometer 42 and a thermal imager 43 are installed on the outside of the temperature measuring shell 41, and an explosion fire extinguishing device 44 is provided inside; wherein the infrared thermometer 42 and the thermal imager 43 are used to locate and feedback the flame area and drive the fire extinguishing device 44 toward the located flame area. The smoke alarm device 2, the infrared thermometer 42 and the thermal imager 43 work together to greatly improve the efficiency and accuracy of fire extinguishing.
[0039] Similarly, if Figures 2 to 4As shown, the fire extinguishing device 44 includes a supply pipe 441 connected to the storage tank 5, which can continuously deliver the explosive fire extinguishing bomb 444. The bottom end of the supply pipe 441 is installed with a thick metal copper sheet cover 442, and the top end is connected to the storage tank 5 through a rotating shaft 443; the explosive fire extinguishing bomb 444 is fixed inside the thick metal copper sheet cover 442, and a sound absorbing material layer 445 is filled between the explosive fire extinguishing bomb 444 and the thick metal copper sheet cover 442. Among them, the explosive fire extinguishing bomb 444 includes a dry water fire extinguishing agent 4441 loaded at the bottom of the bomb body and a charge tube 4442 installed on the upper part of the dry water fire extinguishing agent 4441 using a transitional stepped charge structure, and an ignition fuse 4443 is connected to the charge tube 4442. The infrared thermometer 42 and the thermal imager 43 are configured to trigger the ignition fuse 4443 to ignite the charge tube 4442 to sprinkle the dry water fire extinguishing agent 4441 when the temperature is abnormal. Through these settings, the explosive fire-extinguishing bomb 444 adopts a spherical charge, which makes the area of sprinkling after the explosion wider and the fire-fighting efficiency higher. The charge tube 4442 is surrounded by a particularly thick metal copper sheet cover 442, so that the fragments produced by the explosion after the explosion will not splash out and cause harm to personnel and equipment. Further, polyethylene can also be used to wrap the outside of the dry water fire extinguishing agent 4441, so that the generation of lethal fragments can be further avoided, and personnel and equipment damage can be prevented. In addition, the charge tube 4442 of the explosive fire-extinguishing bomb 444 adopts a transitional stepped charge structure (the specific charge amount of the charge tube 4442 is 1.2%-1.6%), so that the dry water fire extinguishing agent 4441 is in an inverted pyramid shape when scattered, and most of the fire extinguishing agents are scattered radially and downwardly, which is conducive to forming a flat cloud, and the fire extinguishing effect is better than that of the traditional charge structure.
[0040] In actual use, when the smoke alarm device 2 recognizes smoke, it feedback controls the sliding assembly 3, and the sliding assembly 3 slides along the fixed guide rail 1 to the specified position. The infrared thermometer 42 and the thermal imager 43 on the temperature measuring shell 41 will detect the specific position of the flame and control the explosive fire extinguishing device 44 to the specified direction. When the infrared thermometer 42 and the thermal imager 43 detect that the temperature exceeds the preset temperature, the ignition fuse 4443 in the explosive fire extinguishing device 44 will be triggered. The ignition fuse 4443 ignites the charge tube 4442 to scatter the coated dry water fire extinguishing agent 4441. After the previous explosive fire extinguishing bomb 444 is consumed, the storage tank 5 will continuously input new explosive fire extinguishing bombs 444 into the explosive fire extinguishing device 44.
[0041] The above-mentioned dry water fire extinguishing agent 4441 can be made of different materials according to different fire environment conditions. The liquid inside can be distilled water, saline solution, glycerin and similar aqueous solutions that can be mixed and dissolved with water in cosmetics and medicines. The outside is hydrophobic SiO2. The hydrophobic material formed after hydrophobic treatment can effectively prevent the external liquid from contacting the coated internal solution, and the formed coating film has good resistance to high temperature and high pressure. For example, a workshop producing H2 can be equipped with KOH dry water fire extinguishing agent, KOH can suppress H2 explosion, and a factory building with a large number of wood blocks can be equipped with ammonium dihydrogen phosphate dry water fire extinguishing agent. Specifically, in a specific embodiment, the dry water fire extinguishing agent 4441 is made by mixing hydrophobic SiO2 and a salt solution. The preparation method is as follows: first, 5% Nacl is added to deionized water and the solute is completely dissolved; then, the silica and Nacl solution are weighed with an electronic weighing balance to be 1:10, and the high-speed stirrer (6000r / min) is used to stir to obtain it. This type of dry water fire extinguishing agent has both physical and chemical fire extinguishing mechanisms. In terms of chemical fire extinguishing, due to heat, the solution in the dry water fire extinguishing agent 4441 is released to reduce the temperature of the burning object, so that it cannot reach the ignition point. At the same time, SiO2 will adhere to the surface of the burning object, isolating oxygen and preventing combustion, and the metal sodium salt solution in the dry water fire extinguishing agent 4441 can directly interact with the flame. In terms of physical fire extinguishing, a shock wave fire extinguishing mechanism is formed, which refers to the instantaneous generation of high-temperature and high-pressure gas when the explosive fire extinguishing bomb 444 explodes. It expands rapidly and produces a strong mechanical effect on the flame and combustibles, destroying the surface combustion layer and terminating the combustion. It can be seen that the explosion and spreading of the dry water fire extinguishing agent 4441 has both physical and chemical effects, killing two birds with one stone, and greatly improving the efficiency of fire extinguishing.
[0042] When setting and installing the fire-sensing automatic explosion fire extinguishing device, in order to optimize the layout between the structural parts and reserve enough moving and operating space, preferably, the fixed guide rail 1 is suspended on the roof of the house and the distance between the fixed guide rail 1 and the roof of the house is greater than the height of the storage tank 5. In this way, when the sliding assembly 3 slides to change its position, the storage tank 5 above can also move smoothly and synchronously without jamming or even collision and falling accidents.
[0043] Furthermore, in order to prevent the sliding component 3 from falling off and being damaged during the sliding process, which would seriously affect its service life or cause unnecessary troubles in use, it is preferred that the top of the sliding component 3 is tightly buckled under the fixed guide rail 1 through a sliding wheel and can move along the fixed guide rail 1.
[0044] Whether the fire monitoring area is large enough and whether it can cover the entire space is of paramount importance for fire warning. In this embodiment, in order to monitor abnormal smoke occurrence as comprehensively as possible and prevent it before it happens, it is preferred that multiple smoke alarm devices 2 are laid every 10m in the horizontal and vertical directions.
[0045] The preferred embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited thereto. Within the technical concept of the present invention, the technical solution of the present invention can be subjected to a variety of simple modifications, including the combination of various specific technical features in any appropriate manner. In order to avoid unnecessary repetition, the present invention will not further describe various possible combinations. However, these simple modifications and combinations should also be regarded as the contents disclosed by the present invention and belong to the protection scope of the present invention.
