[0002] In modern cities, high-rise buildings are widely adopted due to their high space utilization rate and large building height. Especially in densely populated communities and commercial areas, there are many people living or working in these high-rise buildings. In case of emergencies such as fires, the power distribution system often automatically cuts off the main power supply to ensure the safety of fire-fighting equipment, resulting in emergency lighting becoming the only light source to guide people to evacuate safely.

[0003] However, at present, the emergency channels and public areas of many residential buildings in communities are filled with sundries. Even some users privately charge four-wheel electric vehicles for children in the public area, which greatly increases the hidden dangers in case of a fire. Once a fire occurs, the flammable sundries piled up in the emergency channels and public areas will be ignited, hindering residents from escaping from the building through the safety channels. Seriously, the people escaping in the escape channels may even squeeze the people near the fire source into the fire, causing irreparable losses. The actual effect of the existing emergency lighting system is greatly reduced in case of a fire and cannot effectively provide guarantee for people to escape.

Detailed implementation manner

[0032] In order to enable those skilled in the art of the present technology to better understand the technical solutions in the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0033] As Figures 1 to 7 shown, an intelligent monitoring fire emergency lighting system in an embodiment of the present invention includes a plurality of first protective shells 1, and the plurality of first protective shells 1 are respectively installed in the public areas and emergency passages on each floor of a building, and the first protective shells 1 installed in the emergency passages can respectively correspond to the upper and lower two staircases. A launching mechanism, an intelligent monitoring mechanism, and a plurality of fire extinguishing cannons 4 are provided in the first protective shell 1.

[0034] Among them, the plurality of intelligent monitoring mechanisms communicate with each other. The intelligent monitoring mechanism includes a control module 2 and a monitoring module 6. The monitoring module 6 is a combination of a thermal imaging probe and a ranging camera, and can identify fire sources and escape personnel. The control module 2 controls the launching mechanism to perform corresponding actions according to the data transmitted by the monitoring module 6.

[0035] The fire extinguishing cannon 4 includes a cannon skin 41. The cannon skin 41 is a heat-melting rubber skin. A plurality of expanded graphite balls 42 are installed in the cannon skin 41. Nitrogen-phosphorus flame retardant particles 43 are provided between adjacent two expanded graphite balls 42, and the expanded graphite balls 42 and the nitrogen-phosphorus flame retardant particles 43 are bonded together.

[0036] Specifically, when a fire breaks out in the common area or the escape staircase on a certain floor of a building, the monitoring module 6 identifies the fire source and transmits the fire source information to the control module 2. The control module 2 determines the distance between the first protective shell 1 and the fire origin, and then controls the launching mechanism to continuously launch multiple fire extinguishing guns 4. When the multiple fire extinguishing guns 4 are launched, the launching mechanism controls the fire extinguishing guns 4 to fall into the fire at different landing points by adjusting the launching force. The gun skin 41 on the fire extinguishing gun 4 will melt when encountering fire, and the expanded graphite balls 42 will scatter from the gun skin 41 to cover the flame.

[0037] The expanded graphite balls 42 usually start to expand at temperatures above 300 °C, while the temperature of the flame is basically higher than 1000 °C. When the expanded graphite balls 42 are subjected to temperatures above 800 °C, they will instantaneously expand to more than 300 times their original size, and after expansion, the expanded graphite will become worm-shaped, with a soft internal structure forming a porous structure. This structure has excellent oxidation resistance and high-temperature resistance, and the space between the expanded graphite layers is filled with non-combustible gases, also having excellent oxidation resistance and high-temperature resistance, which can suffocate the flame.

[0038] It should be noted that the hot-melt adhesive used to make the gun skin 41 is a combustible material in traditional concepts. However, according to experiments, when the hot-melt adhesive encounters an open flame, the flame will continuously transfer heat to the hot-melt adhesive. As the temperature continues to rise, the hot-melt adhesive will melt and become thinner and thinner. If the temperature continues to rise, the glue will gradually darken and become harder from its changing properties, and finally turn into coke. Throughout this entire process, the hot-melt adhesive changes from a solid to a liquid and then from a liquid to a solid. Although its properties are constantly changing, they do not burn.

[0039] In addition, when the gun skin 41 melts into a liquid, it will not only drive the expanded graphite balls 42 and nitrogen-phosphorus flame retardant particles 43 to flow on the fire object, increasing the coverage area of the expanded graphite balls 42 and nitrogen-phosphorus flame retardant particles 43 on the fire object, but also its carbonization adheres to the fire object itself. The carbonized hot-melt adhesive covers the surface of the fire object, which can not only help to cut off the oxygen for fire extinguishing, but also enable the expanded graphite balls 42 to be evenly heated, so that their expansion reaches the maximum range, facilitating the covering and extinguishing of the fire object by the expanded expanded graphite balls 42.

[0040] In addition, because nitrogen-phosphorus flame retardant particles 43 are bonded between a pair of expanded graphite balls 42, the nitrogen-phosphorus flame retardant particles 43 can rapidly decompose nitrogen, phosphorus and other compounds at high temperatures after being heated, forming a flame retardant protective layer in the gas phase and gel phase, and will react with the carbon layer formed after the expanded graphite and hot-melt adhesive are heated, forming a dense ceramic-like body to further retard the fire and prevent the fire object from reigniting.

[0041] Further, in order to enable the expanded graphite balls 42 to better cover the burning object, a second airbag 44 is also provided inside the gun barrel skin 41, and a water-based fire extinguishing agent 442 is contained in the second airbag 44. A heat conducting rod 441 is bonded to the second airbag 44, the heat conducting rod 441 penetrates through the gun barrel skin 41, and carbon dioxide 443 is mixed in the water-based fire extinguishing agent 442.

[0042] Specifically, when the fire extinguishing gun 4 is shot out by the launching mechanism and lands, it will be impacted itself. The solubility of the carbon dioxide 443 in the second airbag 44 changes and is precipitated from the water-based fire extinguishing agent 442 to form bubbles. At this time, the air pressure inside the second airbag 44 becomes larger. Also, because the heat conducting rod 441 transfers heat to the second airbag 44, the contact part between the second airbag 44 and the heat conducting rod 441 is heated and melted to become thinner, resulting in the second airbag 44 being no longer able to withstand the increased air pressure and undergoing a slight explosion. And the intensity of the explosion can be controlled by controlling the content of the carbon dioxide 443 dissolved in the water-based fire extinguishing agent 442. When the second airbag 44 explodes, it will perform a secondary ejection on the expanded graphite balls 42 and the nitrogen-phosphorus flame retardant particles 43, making the coverage area of the expanded graphite balls 42 and the nitrogen-phosphorus flame retardant particles 43 on the flame larger and more uniform, achieving a better fire extinguishing effect.

[0043] In addition, when the second airbag 44 explodes, the water-based fire extinguishing agent 442 and the carbon dioxide 443 inside the second airbag 44 are also ejected. After the water-based fire extinguishing agent 442 is sprayed onto the fuel surface, the water separated out from the foam layer forms a water film on the fuel surface, isolating the combustible from the air, thereby achieving the fire extinguishing effect. At the same time, the concentration of oxygen in the air in the combustion area is reduced to prevent re-ignition. And because the density of the carbon dioxide 443 is greater than that of air, it can also cover the flame to enhance the fire extinguishing effect. At the same time, when the second airbag 44 explodes, it can also blast open the burning object, forming an area without combustibles on the ground, facilitating the escape of personnel from this area.

[0044] Furthermore, cracks are provided inside the expanded graphite balls 42, and a hot melt adhesive 421 is used to seal the cracks of the expanded graphite balls 42. Specifically, when the expanded graphite balls 42 come into contact with high temperature, the hot melt adhesive 421 will melt, and the expanded graphite balls 42 as a whole will unfold, further increasing the coverage area of the expanded graphite balls 42 on the flame and achieving a better coverage effect on the flame.

[0045] What is more terrifying in a fire is that if the ignition source is in the indoor area of a household, the shoe cabinets or other cabinets in the public area and the escape passage are suddenly on fire in a large area after being baked. These cabinets are often made of particle boards compressed together. After catching fire, they will collapse, causing the burning cabinet boards to instantly cover the entire public area and the escape passage. The area on fire is relatively large, which will block the escape of the people on the floors above the floor on fire. And after the fire extinguishing gun 4 extinguishes the fire on the boards, the high temperature will still cause the boards to re-ignite.

[0046] At this time, the control module 2 determines that the multiple fire extinguishing guns 4 in the first protective shell 1 cannot completely extinguish the fire, and then issues an instruction to the launching mechanism to make the distance of the fire extinguishing guns 4 it launches gradually longer or shorter. The multiple launched fire extinguishing guns 4 explode when they encounter the fire, and the expanded graphite balls 42 are scattered, isolating a non-combustible escape path to help people escape.

[0047] Meanwhile, because the intelligent monitoring mechanisms in the first protective shells 1 installed on multiple floors communicate with each other and send the number of escape personnel to the intelligent monitoring mechanism on the fire floor. The intelligent monitoring mechanism on the fire floor judges the time when the escape personnel reach the fire floor based on the received data, and then shoots out multiple fire extinguishing guns 4 again. After the second airbag 44 in the fire extinguishing gun 4 explodes, the water-based fire extinguishing agent 442 can absorb heat when evaporating, reducing the temperature of the escape path and ensuring that the escape personnel can quickly pass through the escape floor to ensure the escape of personnel. Since the fire in a high-rise building burns upwards, once the escape personnel pass through the fire floor, they can successfully escape from the building.

[0048] Such as Figure 2 、 Figure 6 and Figure 7 As shown, the launching mechanism includes a launching power supply 3, a launching tube 31, and a storage tube 35. An electromagnet 32 and a magnetic block 33 are provided in the launching tube 31. A first transmission line 321 and a second transmission line 322 are provided on the electromagnet 32, and both the first transmission line 321 and the second transmission line 322 are connected to the launching power supply 3. The electromagnet 32 is fixedly installed in the launching tube 31. Multiple fire extinguishing guns 4 are loaded in the storage tube 35. The nozzle of the storage tube 35 is flush with the upper end surface of the launching tube 31. An opening matching the inner diameter of the storage tube 35 is provided on the launching tube 31, and the fire extinguishing guns 4 in the storage tube 35 can fall into the launching tube 31 under the action of gravity.

[0049] Specifically, there is a complete energized circuit in both the first transmission line 321 and the second transmission line 322. When the launching power supply 3 supplies power to the energized circuit in the first transmission line 321, the electromagnet 32 presents an N-pole magnetic field and attracts the magnetic block 33 with an S-pole magnetic field; when the launching power supply 3 supplies power to the energized circuit in the second transmission line 322, the electromagnet 32 presents an S-shaped magnetic field and repels the magnetic block 33 with the same S-pole magnetic field, so that the magnetic block 33 can reciprocate in the launching tube 31. When the magnetic block 33 is repelled by the electromagnet 32, the fire extinguishing gun 4 in the launching tube 31 can be shot out. And the control module 2 can control the launching power supply 3 to release different amounts of electrical energy to control the sliding speed of the magnetic block 33 in the launching tube 31, thereby controlling the distance of the shot fire extinguishing gun 4.

[0050] Further, the cross-sectional area length of the magnetic block 33 is greater than the length of the nozzle of the storage tube 35. After the fire extinguisher cannon 4 in the launch tube 31 is ejected by the magnetic block 33, the fire extinguisher cannon 4 in the storage tube 35 will fall on the magnetic block 33, and a part of it will be stuck in the storage tube 35. After the magnetic block 33 is attracted by the electromagnet 32 and approaches the electromagnet 32, the fire extinguisher cannon 4 in the storage tube 35 will fall into the launch tube 31, thus enabling continuous firing.

[0051] In addition, by controlling the speed of the magnetic block 33, the fire extinguisher cannon 4 in the launch tube 31 can be pushed away from the position of the nozzle of the storage tube 35. However, at this time, the pushed-away fire extinguisher cannon 4 is still located in the launch tube 31. After the magnetic block 33 approaches the electromagnet 32, the fire extinguisher cannon 4 in the storage tube 35 will still fall into the launch tube 31. Through the above operations, multiple fire extinguisher cannons 4 can be ejected at one time. When people are escaping, ejecting multiple fire extinguisher cannons 4 at one time can quickly extinguish the fire, or rapidly extinguish the fire and cool down the fire scene in real time, ensuring that the escaping personnel can pass through the burning floors to escape.

[0052] Further, as Figure 2 , Figure 3 , Figure 4 , Figure 6 and Figure 8 shown, in order to increase the number of fire extinguisher cannons 4 and facilitate extinguishing large-area fires, there are multiple storage tubes 35. A third slider 351 is fixedly installed on the storage tube 35, and a slide rail 36 matching the third slider 351 is fixedly installed on the first protective shell 1. One fire extinguisher cannon 4 is bonded to the nozzle of the storage tube 35.

[0053] Specifically, in the initial state, one storage tube 35 is located above the launch tube 31 and matches the launch tube 31. The fire extinguisher cannon 4 bonded to the nozzle of another storage tube 35 can seal the storage tube 35 to prevent the fire extinguisher cannon 4 in the storage tube 35 outside the launch tube 31 from falling.

[0054] After the fire extinguisher cannon 4 in the storage tube 35 located above the launch tube 31 is launched, the storage tube 35 on the side of the launch tube 31 walks to directly above the launch tube 31 through the third slider 351 on the slide rail 36. During the walking process of the storage tube 35, the fire extinguisher cannon 4 bonded to the nozzle of the storage tube 35 is blocked by the side wall of the launch tube 31, and thus will fall off from the nozzle of the storage tube 35. When the fire extinguisher cannon 4 bonded to the nozzle of the storage tube 35 falls off, a part of the nozzle of the storage tube 35 has been blocked by the upper end face of the launch tube 31, and the fire extinguisher cannon 4 in the storage tube 35 will not leak out. When the nozzle of the storage tube 35 coincides with the opening opened on the upper end face of the launch tube 31, the fire extinguisher cannon 4 in the storage tube 35 can fall into the launch tube 31 and wait for launch.

[0055] It should be noted that if the fire extinguishing cannon 4 in the second storage tube 35 can be used, it means that the fire has been burning for some time. At this time, the first protective shell 1 will also be affected by high temperature. When the temperature in the first protective shell 1 is higher than 200 °C, the gun skin 41 on the fire extinguishing cannon 4 will start to melt, affecting the firing of the fire extinguishing cannon 4. Therefore, it is necessary to cool down and protect the first protective shell 1.

[0056] Furthermore, as Figures 2 to 10 shown, a second protective shell 5 is sleeved on the first protective shell 1. There is a heat insulation space between the second protective shell 5 and the first protective shell 1. A first groove 11 is formed on the lower panel of the first protective shell 1. A third groove 12 is formed on the groove wall of the first groove 11. A first slider 13 is slidably connected in the third groove 12. A spring 131 is welded on the first slider 13. One end of the spring 131 away from the first slider 13 is welded on the bottom wall of the third groove 12. A clamping plate 15 for locking the first slider 13 is installed on the first protective shell 1. A second groove 111 communicating with the third groove 12 is formed on the panel of the first protective shell 1. The clamping plate 15 is inserted into the second groove 111.

[0057] Specifically, when the storage tube 35 moves, the fire extinguishing cannon 4 adhered to the nozzle of the storage tube 35 is blocked by the side wall of the launch tube 31 and falls into the first groove 11, hitting the clamping plate 15 and knocking the clamping plate 15 out of the second groove 111. At this time, without the block of the clamping plate 15, the spring 131 elastically elongates, and the first slider 13 slides towards the opening of the first groove 11 to block the first groove 11. At this time, if the second protective shell 5 is baked, the temperature will rise. When the temperature of the second protective shell 5 rises above 200 °C, the gun skin 41 melts. If the temperature of the second protective shell 5 continues to rise, the expanded graphite balls 42 will start to expand. Because the first groove 11 is blocked by the first slider 13, the pressure after the expansion of the expanded graphite balls 42 will fill the heat insulation space between the first protective shell 1 and the second protective shell 5, and the expanded expanded graphite balls 42 can insulate heat, protecting the first protective shell 1 and preventing the temperature in the first protective shell 1 from being too high. It can not only ensure the smooth firing of the fire extinguishing cannon 4, but also protect the electrical components in the first protective shell 1.

[0058] In addition, due to the protection of the second protective shell 5, the temperature in the heat insulation space rises slowly, and the melted gun skin 41 in the heat insulation space will not quickly carbonize, but will remain in a liquid state for some time. When the expanded graphite balls 42 start to expand, the gun skin 41 in a liquid state can also drive the expanded graphite balls 42 to cover the lower part of the heat insulation space, facilitating the expansion of the expanded graphite balls 42 to fill the entire expansion space.

[0059] Meanwhile, since the distance when the fire extinguishing cannon 4 drops is small, not much carbon dioxide 443 in the second airbag 44 is released, the pressure increase in the second airbag 44 is limited, and the second airbag 44 will not explode after being heated by the heat conducting rod 441. After the second airbag 44 is pierced by the heat conducting rod 441, the water-based fire extinguishing agent 442 in the second airbag 44 is released, and the water-based fire extinguishing agent 442 will adhere to the expanded graphite balls 42 and be mixed in the expansion space, playing a better heat insulation role.

[0060] Further, as Figure 2 , Figure 9 , Figure 10 and Figure 11 shown, a fourth groove body 14 matching the third groove body 12 is provided on the groove wall of the first groove body 11. A sliding column 16 is slidably connected to the fourth groove body 14. The sliding column 16 is provided with a spike portion. A first through hole 161 is also provided on the sliding column 16. A first cavity 17 matching the fourth groove body 14 is provided on the first protective shell 1. A first micro hole 18 communicating with the first cavity 17 is provided on the inner wall of the first protective shell 1. A first airbag 171 is fixedly installed in the first cavity 17. A second through hole 311 is provided on the launching tube 31.

[0061] Specifically, while the first slider 13 blocks the first groove body 11, the first slider 13 also enters the fourth groove body 14 to push the sliding column 16 so that the sliding column 16 is inserted into the first airbag  171. The first airbag 171 is filled with compressed inert gas, and the nitrogen is slowly released through the first through hole 161. The released inert gas fills the first cavity 17 and enters the inside of the first protective shell 1 from the first micro hole 18. The inert gas inside the first protective shell 1 enters the launching tube 31 from the second through hole 311. At this time, both the inside of the first protective shell 1 and the launching tube 31 are under positive pressure, preventing the high-temperature gas at the fire scene from entering the launching tube 31, preventing the fire extinguishing cannon 4 inside the launching tube 31 from expanding due to heat, and ensuring that the fire extinguishing cannon 4 can be successfully launched.

[0062] In addition, a slideway 312 is also provided on the inner wall of the launching tube 31. A second slider 34 matching the slideway 312 is welded on the magnet 33. Specifically, the magnet 33 is suspended in the launching tube 31 through the second slider 34 and does not block the second through hole 311, ensuring that the inert gas can continuously enter at the second through hole 311 when the magnet 33 reciprocates in the launching tube 31. In addition, since the magnet 33 does not contact the inner wall of the launching tube 31, the friction with the launching tube 31 can also be reduced, accelerating the reciprocating speed of the magnet 33.

[0063] Further, a second cavity 51 is formed on the second protective shell 5, and a fireproof gel 52 is filled in the second cavity 51. Second micropores 53 communicating with the second cavity 51 are formed on the outer wall of the second protective shell 5. A communicating pipe 19 is fixedly connected between the second protective shell 5 and the first protective shell 1, and the communicating pipe 19 can realize the conduction between the first cavity 17 and the second cavity 51. Specifically, after an inert gas is filled into the first protective shell 1, the pressure increases, and the inert gas will enter the second cavity 51 through the communicating pipe 19, squeezing out the fireproof gel 52 in the second cavity 51 to form a protection on the outer wall of the second protective shell 5 and reducing the temperature of the second protective shell 5. After the temperature of the second protective shell 5 is reduced, it can also ensure that the temperature in the first protective shell 1 will not rise excessively in a short time.

[0064] During use, as Figures 1 to 7 shown, the control module 2 judges the distance between the ignition point and the first protective shell 1 through the monitoring module 6, and controls the launching mechanism to launch the fire extinguishing cannon 4 to the fire location. When the fire extinguishing cannon 4 is launched, the magnet 33 will first collide with the fire extinguishing cannon 4, and the fire extinguishing cannon 4 will collide with the fire object again when it lands at the fire location. The carbon dioxide 443 in the second airbag 44 will precipitate from the water-based fire extinguishing agent 442, and at this time, the air pressure in the second airbag 44 increases. When the fire extinguishing cannon 4 lands on the fire object, the flame melts the gun skin 41, and the high temperature will be transmitted to the second airbag 44 through the heat conducting rod 441, making the second airbag 44 thinner. After the second airbag 44 becomes thinner, it can no longer withstand the higher air pressure in the second airbag 44 and explodes.

[0065] When the second airbag 44 explodes, it can launch the expanded graphite balls 42 and the nitrogen-phosphorus flame retardant particles 43 again, expanding the area of the expanded graphite balls 42 and the nitrogen-phosphorus flame retardant particles 43 on the fire object. When the expanded graphite balls 42 encounter the flame, they absorb heat and instantly expand to cover the fire object, forming a carbon layer to isolate the air on the fire object and extinguish the flame. At the same time, the nitrogen-phosphorus flame retardant particles 43 decompose at high temperature and react with the carbon layer formed after the expansion of the expanded graphite balls 42 to form a dense ceramic-like body, preventing the flame from spreading from other places to here and causing re-ignition here. In this way, after multiple fire extinguishing cannons 4 are fired, the fire at the fire scene can be extinguished. In addition, if the area of the fire scene is too large, after multiple fire extinguishing cannons 4 extinguish the flame, they will form a non-combustible passage to ensure the escape of the escapees.
