Description

Technical Field

[0001] This invention relates to the field of fire protection technology, and in particular to an independent automatic tracking and positioning jet fire extinguishing device. Background Technology

[0002] An automatic tracking and positioning jet extinguishing system is a fire protection system that detects early-stage fires using fire detection components, automatically tracks and locates them, and extinguishes the fire using automatic control methods. This system achieves automatic detection, tracking, and location of fires through detection devices and employs intelligent control to ensure the precise implementation of jet extinguishing. Currently, automatic tracking and positioning jet extinguishing devices are mainly installed in a fixed manner, obtaining the extinguishing medium by connecting to an external fire protection piping network.

[0003] However, most existing automatic tracking and positioning jet fire extinguishing devices are fixed structures that rely on external fire hydrant networks to provide the extinguishing medium, and cannot independently achieve very early fire detection and extinguishing. Some mobile automatic tracking and positioning jet fire extinguishing devices are large and inconvenient to move, making it difficult to flexibly extinguish fires at distant locations in actual use.

[0015] Beneficial effects This invention provides an independent, automatic tracking and positioning jet fire extinguishing device. It has the following advantages: (1) This independent automatic tracking and positioning jet fire extinguishing device can be moved by carrying the fire extinguisher on a mobile cart. It can be used in two ways: the fire extinguisher can be combined with the external pipe or separated. Depending on the actual use, when it is necessary to extinguish a fire at a distance and a small area, the mobile cart can be pushed to carry the fire extinguisher to extinguish the fire at the fire point. When it is necessary to extinguish a fire at a selected area, it can achieve early fire detection and extinguishing without relying on the external pipeline to provide fire extinguishing medium and power supply. It can automatically find the fire source and spray fire extinguishing medium to extinguish the fire at a fixed point. The compressed air in the gas cylinder is depressurized through the manifold and enters the fire extinguishing agent storage tank. The perfluorohexanone fire extinguishing agent is delivered to the nozzle through the first spray pipe and sprayed at the fire source to achieve second-level fire extinguishing. It can also combine the fire extinguisher with the external pipe to spray the fire extinguishing agent inside the fire extinguisher to the fire point for rapid fire extinguishing.

[0016] (2) The independent automatic tracking and positioning jet fire extinguishing device releases the limiting component to block and limit the connecting sleeve and the movable sleeve. After the connecting sleeve is stably connected to the upper end of the connecting pipe, the movable sleeve is driven to descend. The connecting sleeve and the movable sleeve descend in steps. After ensuring that the connecting sleeve and the connecting pipe are stably connected, the movable sleeve descends and drives the piercing tube inside to pierce the sealing film, thereby connecting the fire extinguisher with the internal part of the external pipe. This allows the fire extinguisher to be quickly connected to the spray pipeline composed of the external pipe, the first spray pipe and the nozzle, so as to realize automatic identification and fire extinguishing at the fire point.

[0017] (3) The independent automatic tracking and positioning jet fire extinguishing device can flexibly select the usage mode of the device according to the actual fire scene and the characteristics of the protected object, so as to meet the fire extinguishing needs of fire points at ultra-long distances, fires of high-value precision equipment, and fire points with large fire loads and enclosed spaces. It can not only ensure the fire extinguishing effect at the fire point, but also take into account cost control considerations. Attached Figure Description

[0033] Working principle of the invention: When the protected object is extremely valuable precision equipment or important data, and the fire extinguishing process is required to be absolutely safe for people and the environment, with zero damage to equipment and no residue, the first solenoid valve 17 seals the end connecting the external pipe 4 to the first spray pipe 3. The housing 1, along with the internal extinguishing agent storage tank 11, gas cylinder 12, manifold 13, and first spray pipe 3, can be combined and used independently. The extinguishing agent storage tank 11 contains perfluorohexanone extinguishing agent. This independent automatic tracking and positioning jet fire extinguishing device consists of the extinguishing agent storage tank 11, gas cylinder 12, manifold 13, first spray pipe 3, nozzle 14, and control panel. In standby mode, the infrared-ultraviolet composite locator continuously detects the protected area. Upon detecting a fire source, the locator quickly completes a 330° horizontal and 110° vertical scan and positioning, and the control panel issues an audible and visual alarm. Upon startup, compressed air in cylinder 12 is depressurized via manifold 13 and enters extinguishing agent storage tank 11. Perfluorohexanone extinguishing agent is then delivered to nozzle 14 via first spray pipe 3, spraying directly at the fire source to achieve second-level fire extinguishing. Manifold 13 includes connecting pipe 902, pressure reducer, and safety relief device. Connecting pipe 902 is a pressure-resistant pipe meeting the working pressure; the pressure reducer is manufactured according to GB / T7899-2006, with a pressure reduction characteristic deviation not exceeding 10% of the nominal value; the safety relief device is manufactured according to GB / T12241-2021, with a pressure relief action pressure of 1.25 times and not exceeding 95% of the strength test pressure. The system features automatic and manual control, self-storage power supply (capable of operation for over 12 hours without external power), and remote network monitoring. The fire extinguishing test requires extinguishing open flames within 30 seconds and preventing reignition within 30 minutes. Under normal circumstances, the mobile cart 8 and the fire extinguisher 9 are stored inside the storage box 5. When the value of the protected object is relatively low, but the fire load is large, the space is enclosed, and the primary objective is to forcefully cool and extinguish the fire, while cost control is an important consideration, the mobile cart 8 and the fire extinguisher 9 mounted on the mobile cart 8 are placed inside the storage box 5. When it is necessary to use the extinguishing agent stored inside the fire extinguisher bottle 901 for fire extinguishing, firstly, the two sets of limiting components 20 located at the lower end of the fixed sleeve 1001 release the limiting of the connecting sleeve 1004 and the movable sleeve 1003 respectively. Among them, both limiting pins 2003 block the bottom of the movable sleeve 1003, and one of the limiting pins 2003 extends outward to block the bottom of the connecting sleeve 1004. When component 10 is installed on connecting pipe 902, the limiting pin 2003 in one of the limiting components 20 is first driven to retract into the mounting sleeve 2001, releasing the restriction on the lower end of connecting sleeve 1004. At this time, under the action of the second spring 1005, the connecting sleeve 1004 is pushed outward until it aligns with the upper end of connecting pipe 902. Then, both limiting pins 2003 are simultaneously driven to retract into the mounting sleeve 2001. At this time, under the synergistic action of the first spring 1002, the first coil 1008, and the first moving iron core 1007, the movable sleeve 1003 is pushed downward as a whole until it covers the outside of connecting pipe 902. As the movable sleeve 1003 moves downward, it drives the telescopic tube 403 to extend, thereby driving the internal fixed connection. The puncture tube 1006 punctures downwards simultaneously, and through the puncture head 1009 at its end, it punctures the sealing film 905 inside the connecting tube 902. The puncture head 1009 is simply a V-shaped rod with a sharp lower end. The lower end of the puncture tube 1006 is open, allowing the carbon dioxide extinguishing agent stored inside the fire extinguisher bottle 901 to enter the first spray pipe 3 through the puncture tube 1006 and the interior of the outer connecting pipe 4. The carbon dioxide extinguishing agent is then sprayed outwards through the nozzle 14 at the end of the first spray pipe 3 to extinguish the fire. Under the regulation and control of the second solenoid valve 18, the two sets of puncture components 10 are respectively connected to the two connecting pipes 902, so that the extinguishing agents stored inside the two fire extinguisher bottles 901 are respectively connected to the outer connecting pipe 4. The extinguishing agent is sprayed into the interior of the first spray pipe 3 and then through the nozzle 14 at the end of the first spray pipe 3 to the ignition point. When the movable sleeve 1003 covers the outer wall of the connecting sleeve 1004 downwards, the first coil 1008 and the first moving iron core 1007 exert a downward force on the movable sleeve 1003 to ensure a stable connection between the connecting sleeve 1004 and the upper end of the connecting pipe 902. The connecting sleeve 1004 and the puncture tube 1006 are connected by a common reciprocating motion sealing structure. After the connecting sleeve 1004 is stably connected to the upper end of the connecting pipe 902, the end of the fixing bolt 1010 is pressed against the outer wall of the fixing sleeve 1001 by rotating the fixing bolt 1010. The extinguishing agent inside the fire extinguisher bottle 901 is used up.When fire extinguisher bottle 901 needs to be replaced, the passage of the corresponding fire extinguisher bottle 901 is blocked by the second solenoid valve 18. The interaction between the first coil 1008 and the first moving iron core 1007 causes the movable sleeve 1003 to move upward as a whole. Then, the lifting rod 1011 is pushed upward. After the movable sleeve 1003 and the connecting sleeve 1004 are reset, the movable sleeve 1003 and the connecting sleeve 1004 are fixed again by the two sets of limiting components 20. Then, the mobile trolley 8 can be pulled outward as a whole to replace the fire extinguisher bottle 901. After replacement, the fire extinguisher bottle 901 is pushed back into the storage box 5. The two second limiting clips 16 set on the inner wall of the storage box 5 can respectively lock and fix the two fire extinguisher bottles 901. In actual use, carbon dioxide extinguishing agent is often used in the two fire extinguishers 9, but users can also choose other types of extinguishing agents according to the actual situation. The booster pump 15 installed on the connecting pipe 401 ensures that other types of extinguishing agents are sprayed to the fire point after passing through the first spray pipe 3 and the nozzle 14. The booster pump 15 is a common structure and will not be described in detail here. When the fire point is small and far away, the device is inconvenient to move. In this case, the two fire extinguishers 9 are placed on the mobile cart 8. Pulling the mobile cart 8 can move the two fire extinguishers 9 to the vicinity of the fire point. The carbon dioxide extinguishing agent stored in the fire extinguisher bottle 901 can be sprayed directly to the fire point through the handle 903 and the second spray pipe 904 set at the upper end of the fire extinguisher 9, so as to extinguish the fire point efficiently and conveniently.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of this invention is defined by the appended claims and their equivalents.
