Description

Technical Field

[0001] This invention relates to the field of fire extinguishing equipment, and in particular to a non-pressurized water-based fire extinguishing device. Background Technology

[0002] Chinese Patent CN223096017U discloses a triggering device for a mining fire extinguisher, including a fire extinguishing bottle. A connector is threaded to the top of the fire extinguishing bottle, and a handle bracket is integrally connected to the connector. An installation ring is fixedly connected inside the connector, and an inner plug sleeve is fixedly connected to the bottom of the installation ring. Several sealing fins are fixedly connected to the outer wall of the inner plug sleeve. An installation ring groove is formed at the bottom of the installation ring, and a sealing ring is installed inside the groove. The sealing ring is in close contact with the top of the fire extinguishing bottle, and the sealing fins are in close contact with the inner wall of the fire extinguishing bottle. A triggering assembly is installed on the handle bracket. In this technology, the fire extinguishing bottle in the fire extinguisher is pressurized and is easily damaged by impacts during transportation and installation, leading to pressure leakage and overall failure of the fire extinguishing device. Summary of the Invention

[0003] The purpose of this invention is to provide a non-pressurized water-based fire extinguishing device, which uses a non-pressurized agent storage tank and a split-type activation device; it is a completely new type of fire extinguishing device.

[0004] The technical solution adopted in this invention is as follows: This invention provides a non-pressurized water-based fire extinguishing device, including a non-pressurized agent storage tank and a separate starting device; the agent storage tank is sealed with a water-based fire extinguishing agent, and the tank opening is equipped with a cap, which has an air inlet and a fire extinguishing agent outlet, and the air inlet and fire extinguishing agent outlet are sealed with a ruptureable first diaphragm; the starting device mainly includes a gas cylinder and a triggering mechanism, the gas cylinder is sealed with high-pressure gas, the gas cylinder opening is sealed with a ruptureable second diaphragm, and the gas cylinder opening is connected to the air inlet on the agent storage tank through a second air guide tube; the triggering mechanism includes at least one movable puncture member, which is installed at the gas cylinder opening and points towards the second diaphragm at the gas cylinder opening; the puncture member can be moved towards the second diaphragm at the gas cylinder opening by external force, thereby realizing the puncture action.

[0005] The beneficial effects of this invention are as follows: This invention provides a non-pressurized water-based fire extinguishing device. Before activation, the agent storage tank is in a closed state (standby state). When activated, the piercing element in the activation device punctures the second diaphragm at the mouth of the gas cylinder under external force. High-pressure gas from the gas cylinder is ejected from the puncture in the second diaphragm, travels through the second gas guide pipe to the air inlet on the agent storage tank, punctures the first diaphragm at the air inlet, and finally enters the agent storage tank. As the pressure inside the agent storage tank increases, the extinguishing agent inside is forced to puncture the first diaphragm at the extinguishing agent outlet and is ejected. The extinguishing agent is then transported to the fire-prone area via the first guide pipe and spray pipe, and finally sprayed out from the spray pipe to extinguish the fire in the fire-prone area. This device is suitable for fire prevention in the field of new energy storage, such as fire prevention for energy storage battery boxes, battery module compartments, and other equipment. This device is suitable for fire protection in the power distribution network sector, such as high and low voltage switchgear, ring main units, and transformer enclosures; it is also suitable for fire protection in the communications infrastructure sector, such as 5G base station cabinets, data center cabinets, and unattended computer rooms; and it is suitable for special industries, such as mining electrical equipment and explosion-proof cabinets in chemical plants. The chemical storage tank in this device does not require pressurization, eliminating the potential hazards caused by excessive pressure. Furthermore, this product does not require power to start, eliminating the potential hazards caused by electric drive. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0035] The non-pressurized water-based fire extinguishing device provided in this application mainly includes a non-pressurized agent storage tank 1 and a separate starting device. The agent storage tank 1 contains a sealed water-based fire extinguishing agent. The starting device mainly includes a gas cylinder 6 and a triggering mechanism. The gas cylinder 6 contains a sealed high-pressure gas and is connected to the agent storage tank 1 via a gas delivery pipe. The triggering mechanism is used to break the seal of the gas cylinder 6. After the seal of the gas cylinder 6 is broken, the high-pressure gas stored inside is sent to the agent storage tank 1 through the gas delivery pipe. The high-pressure gas enters the agent storage tank 1 through the air inlet 102 and forces the fire extinguishing agent in the agent storage tank 1 out through the fire extinguishing agent outlet 103, thereby achieving the output action. The specific structure of each part is illustrated below.

[0036] See Figure 1 The diagram shown is a schematic of the first non-pressurized water-based fire extinguishing device provided in this application. In this embodiment, the agent storage tank 1 can be a stainless steel bottle, and the agent storage tank 1 stores a water-based fire extinguishing agent. In this invention, the water-based fire extinguishing agent can use existing publicly available formulas, and this invention does not impose any restrictions on this. The water-based fire extinguishing agent is mainly composed of water, penetrant, flame retardant, and other additives. The internal product model is named S-100-(-35℃)-XY / water-based fire extinguishing agent, the minimum operating temperature is -30℃, and the fire extinguishing rating is 1A.

[0037] like Figure 2 The diagram shows the structure of the first type of extinguishing agent storage tank 1 provided in this application. A stainless steel cap 101 is installed at the opening of the extinguishing agent storage tank 1 to seal the opening. In one specific embodiment, the cap 101 is threaded onto the opening of the extinguishing agent storage tank 1 and sealed with a rubber sealing ring. The cap 101 has at least one air inlet 102 and at least one extinguishing agent outlet 103. Figure 2In the illustrated scheme, the bottle cap 101 is provided with an air inlet 102 and an extinguishing agent outlet 103. To prevent leakage of extinguishing agent from the air inlet 102 and the extinguishing agent outlet 103 during the standby state of the agent storage tank 1 and to achieve a seal, the air inlet 102 and the extinguishing agent outlet 103 are sealed with a ruptureable first diaphragm 104. The first diaphragm 104 can be made of aluminum foil or alloy film, such as a galvanized steel diaphragm. The thickness of the first diaphragm 104 can be 0.1-0.3 mm, preferably 0.25 mm. By using the first diaphragm 104 for sealing, external moisture is prevented from entering the agent storage tank 1, ensuring that the extinguishing agent will not become ineffective during the standby period of several years.

[0038] like Figure 1 As shown, the extinguishing agent outlet 103 on the bottle cap 101 is connected to the spray pipe 3 via the first guide pipe 2. The spray pipe 3 covers a certain space, thus forming a fire-resistant zone 4. Multiple atomizing nozzles can be installed on the spray pipe 3. After the agent storage tank 1 is triggered, the first diaphragm 104 on the air inlet 102 and the extinguishing agent outlet 103 is broken, and the extinguishing agent is sprayed out through the extinguishing agent outlet 103, the first guide pipe 2, and the spray pipe 3 to extinguish the fire in the covered fire-resistant zone 4.

[0039] In this application, in order to discharge as much extinguishing agent as possible from the extinguishing agent storage tank 1 after activation, thereby reducing residue, a siphon pipe 105 can be installed at the extinguishing agent outlet 103 of the cap 101. For example... Figure 2 As shown, the siphon tube 105 is installed inside the bottle cap 101; after the bottle cap 101 is assembled with the agent storage tank 1, the siphon tube 105 extends into the agent storage tank 1; one end of the siphon tube 105 inside the agent storage tank 1 is the liquid inlet port, and the liquid inlet port of the siphon tube 105 needs to be located at the bottom of the extinguishing agent so that most of the extinguishing agent in the agent storage tank 1 can be discharged through the siphon tube 105.

[0040] Figure 2 The medicine storage tank 1 shown is placed vertically with the opening of the medicine storage tank 1 at the top. The siphon tube 105 in this placement state is a straight tube. The upper end of the siphon tube 105 is connected to the bottle cap 101 and is located below the first diaphragm 104. The lower end of the siphon tube 105 is close to the bottom of the medicine storage tank 1.

[0041] like Figure 3 The diagram shown is a schematic representation of the internal structure of the first type of extinguishing agent storage tank 1 in its horizontal placement state. The first type of extinguishing agent storage tank 1 in this application can also be placed horizontally; in this state, the siphon pipe 105 is a bent pipe, with the inlet port of the bent pipe facing the side wall of the extinguishing agent storage tank 1, and the inlet port is located at the bottom of the extinguishing agent in the horizontal placement state.

[0042] Furthermore, in this application, a first air guide tube 106 may be provided on the air inlet 102 of the bottle cap 101, and the first air guide tube 106 is installed inside the bottle cap 101; for example Figure 2 As shown, after the bottle cap 101 is assembled with the agent storage tank 1, the first gas guide tube 106 extends into the agent storage tank 1; after the high-pressure gas breaks through the first diaphragm 104 at the air inlet 102, it directly enters the extinguishing agent through the first gas guide tube 106. The high-pressure gas compresses and tumbles the agent in the extinguishing agent, making the extinguishing agent spray more quickly.

[0043] like Figure 1 As shown, the air inlet 102 of the extinguishing agent storage tank 1 is connected to the starting device via the second air guide pipe 5. In this application, the starting device is used to provide high-pressure gas to the extinguishing agent storage tank 1, thereby forcing out the extinguishing agent in the extinguishing agent storage tank 1. The starting device and the extinguishing agent storage tank 1 are two relatively independent parts and can be installed separately.

[0044] like Figure 4 The diagram shown is a schematic representation of the starting device of this application. The starting device mainly includes a gas storage cylinder 6 and a triggering mechanism. The gas storage cylinder 6 stores high-pressure gas, which can be carbon dioxide or nitrogen. The opening of the gas storage cylinder 6 is sealed with a destructible second diaphragm 601, which can be made of a nickel sheet with a thickness of 0.1mm-0.5mm, preferably 0.3mm. The second diaphragm 601 can be sealed to the opening of the gas storage cylinder 6 by welding or pressing. Furthermore, the opening of the gas storage cylinder 6 is connected to the air inlet 102 on the pharmaceutical storage tank 1 via a second air guide pipe 5.

[0045] In this application, a triggering mechanism is used to break the second diaphragm 601 at the opening of the gas cylinder 6, thereby releasing the high-pressure gas inside the gas cylinder 6 and delivering it to the drug storage tank 1 via the second gas guide tube 5. The triggering mechanism includes at least one movable puncture member 7, which is installed at the opening of the gas cylinder 6 and points towards the second diaphragm 601 at the opening of the gas cylinder 6. The puncture member 7 can be moved towards the second diaphragm 601 at the opening of the gas cylinder 6 by external force, thereby achieving the puncture action.

[0046] In one specific embodiment, the puncture device 7 is installed at the mouth of the gas cylinder 6 via a bottle head valve body 8. For example... Figure 5 The diagram shown is a schematic diagram of the valve body 8 installed at the mouth of the gas cylinder 6 of this application. Figure 6 The diagram shown is a schematic representation of the internal structure of the bottle head valve body 8 after it has been cut open. In one specific embodiment, the bottle head valve body 8 is cylindrical in shape, and a stepped through hole is provided at the axis of the bottle head valve body 8; as shown... Figure 7 The diagram shown is a structural illustration of the stepped through-hole at the 8th axis of the bottle head valve body in this application. (See diagram for reference.) Figure 7 As shown, the stepped through hole of the bottle head valve body 8 forms three receiving spaces and one puncture through hole 804, which are named the first receiving space 801, the second receiving space 802, and the third receiving space 803 respectively for ease of description. Figure 7In the middle, from bottom to top, there are a first receiving space 801, a puncture through hole 804, a second receiving space 802, and a third receiving space 803. The diameter of the second receiving space 802 is smaller than that of the first receiving space 801 and the third receiving space 803, and the diameter of the puncture through hole 804 is smaller than that of the second receiving space 802. In addition, a vent 805 is provided on the side of the bottle head valve body 8, and the vent 805 is connected to a stepped through hole at the axis. The vent 805 is used for venting. Figure 8 The vent 805 shown is vertically connected to the second accommodating space 802.

[0047] Combination Figure 6 The first receiving space 801 is used to accommodate the neck of the gas cylinder 6. During installation, an external thread is provided at the neck of the gas cylinder 6, and an internal thread is provided on the inner wall of the first receiving space 801. The neck of the gas cylinder 6 is threaded into the first receiving space 801. Since the neck of the gas cylinder 6 is sealed with a second diaphragm 601, to prevent damage to the second diaphragm 601 during assembly and subsequent leakage, in a preferred embodiment, the diameter of the neck of the gas cylinder 6 is reduced to form a variable-diameter neck. The diameter of the variable-diameter neck is smaller than the diameter of the first receiving space 801, and the diameter of the second diaphragm 601 on it is also smaller than the diameter of the first receiving space 801. This structural design ensures that the second diaphragm 601 will not come into contact with or rub against the inner wall of the first receiving space 801 during assembly, preventing wear on the edge of the second diaphragm 601. Furthermore, an annular wear-resistant pad 9 can be added above the second diaphragm 601 to prevent damage from friction between the second diaphragm 601 and the annular edge of the top of the first receiving space 801 when the second diaphragm 601 reaches the top. The wear-resistant pad 9 can be made of graphite nylon. The wear-resistant pad 9 can be bonded to the upper surface of the second diaphragm 601.

[0048] Combination Figure 6 Understood, the third accommodating space 803 is used to accommodate the puncture assembly, which includes a puncture guide sleeve 10, a puncture element 7, and a puncture return spring 11. For example... Figure 8 The diagram shown is a further cross-sectional view of the internal structure of the puncture guide sleeve 10. The puncture guide sleeve 10 is cylindrical in shape. A guide groove 1001 is provided along the axis inside the puncture guide sleeve 10, extending downwards through the lower surface of the puncture guide sleeve 10. A guide through hole 1002 is provided on the top surface of the guide groove 1001, with a diameter smaller than that of the guide groove 1001, extending through the upper surface of the puncture guide sleeve 10. A movable puncture component 7 is installed inside the puncture guide sleeve 10.

[0049] like Figure 9 The diagram shown is a structural illustration of a puncture device 7 according to this application. Figure 9In the illustrated design, the puncture component 7 comprises three parts: a puncture part 701, a puncture limiting part 702, and a puncture guide rod 703. The puncture part 701 is cylindrical with a sharp head at its bottom. The puncture part 701 is mounted on the puncture limiting part 702; specifically, a cylindrical mounting platform 704 is provided in the center of the disc-shaped puncture limiting part 702, and a mounting hole 705 is provided in the center of the mounting platform 704. The upper end of the puncture part 701 is inserted into or threaded into the mounting hole 705. Furthermore, to facilitate the installation of the puncture return spring 11, an annular groove 706 is provided around the mounting platform 704. The cylindrical puncture guide rod 703 is connected to the puncture limiting part 702.

[0050] Please refer to Figure 8 Understand the assembly relationship between the puncture component 7 and the puncture guide sleeve 10. For example... Figure 8 As shown, the puncture member 7 is inserted into the guide groove 1001 at the bottom of the puncture guide sleeve 10, and the puncture guide rod 703 on the puncture member 7 extends outward through the guide through hole 1002 on the puncture guide sleeve 10. The puncture limiting part 702 on the puncture member 7 and the guide groove 1001 in the puncture guide sleeve 10 are in clearance fit, and the puncture limiting part 702 can move within the guide groove 1001; the puncture part 701 on the puncture member 7 extends downward beyond the guide groove 1001. A puncture return spring 11 is fitted on the puncture part 701, and the puncture return spring 11 can specifically be a helical spring. The top part of the helical spring is inserted into the annular groove 706 of the puncture limiting part 702, and the bottom part of the helical spring is inserted into the third receiving space 803. After assembly, the annular groove 706 on the puncture limiting part 702 and the third receiving space 803 are vertically opposite each other, restricting the puncture return spring 11.

[0051] Please refer to Figure 8Understand the assembly relationship between the above-mentioned puncture assembly and the bottle head valve body 8. The puncture guide sleeve 10 has an external thread, and the third receiving space 803 has an internal thread. The puncture guide sleeve 10 is threadedly connected within the third receiving space 803. After assembly, the puncture return spring 11 pushes the puncture piece 7 upwards. At this time, the puncture limiting part 702 is located at the top of the guide groove 1001, and the cap post guide through hole 1002 is also present. After assembly, the puncture part 701 is located inside the puncture return spring 11, pointing towards the bottle opening of the gas cylinder 6. Pressing down on the puncture guide rod 703 on the puncture piece 7 causes the puncture piece 7 to move downwards. The puncture part 701 on the puncture piece 7 can pass through the puncture through hole 804 to break the second diaphragm 601 on the bottle opening of the gas cylinder 6, forming a rupture. When the downward pressure is removed, the puncture reset spring 11 pushes the puncture piece 7 upward to reset it; at this time, the rupture on the second diaphragm 601 is fully exposed, and the high-pressure gas in the gas storage cylinder 6 enters the upper space through the puncture through hole 804, and then sprays out through the gas outlet 805 into the second gas guide tube 5. The high-pressure gas is sent to the medicine storage tank 1 through the second gas guide tube 5, which breaks the first diaphragm 104 on the air inlet 102 of the medicine storage tank 1, and finally the high-pressure gas enters the medicine storage tank 1.

[0052] In a preferred embodiment, a first sealing ring 12 is provided at the connection structure between the puncture guide sleeve 10 and the bottle head valve body 8. For example... Figure 8 As shown, an annular first sealing groove 1003 is provided on the outer circumferential surface of the puncture guide sleeve 10, and a first sealing ring 12 is installed in the first sealing groove 1003. After assembly, the first sealing ring 12 and the inner wall of the third receiving space 803 are in an interference fit. This design can prevent high-pressure gas from leaking from this connection.

[0053] In a preferred embodiment, a second sealing ring 13 is provided at the connection structure between the puncture member 7 and the puncture guide sleeve 10. For example... Figure 8 As shown, an annular second sealing groove 1004 is further provided within the guide hole 1002 of the puncture guide sleeve 10; a second sealing ring 13 is installed within the second sealing groove 1004. After assembly, the puncture guide rod 703 on the puncture member 7 passes through the second sealing ring 13. This design can prevent high-pressure gas from leaking from this connection.

[0054] In a preferred embodiment, an internal thread is provided at the outer port of the vent 805 of the bottle head valve body 8, and a vent pipe connector 14 is threaded onto the vent pipe connector 14. The vent pipe connector 14 has two threaded connection ends and an internal ventilation channel. The vent pipe connector 14 is used for quick connection to the second vent pipe 5.

[0055] In a preferred embodiment, to prevent damage to the gas cylinder 6 from impacts, a gas cylinder cover 15 can be installed over the gas cylinder 6 for protection. For example... Figure 10 The image shown is a diagram illustrating the gas cylinder cover 15 fitted over the gas cylinder 6 of this application. Figure 10As shown, the gas cylinder cover 15 is a cylindrical body with an internal thread at its top opening. The cylinder head valve body 8 is threadedly connected to the top opening of the gas cylinder cover 15, and the cylinder head valve body 8 has an external thread corresponding to the opening of the gas cylinder cover 15. Furthermore, an annular third sealing groove 806 can be provided at the opening of the cylinder head valve body 8, and a third sealing ring 16 is installed within the third sealing groove 806. After assembly, the third sealing ring 16 seals the connection between the gas cylinder cover 15 and the cylinder head valve body 8. The gas cylinder cover 15 can be made of metal or high-strength engineering plastic. This gas cylinder cover 15 encloses the weak points of the gas cylinder 6 (such as the shoulder and bottom), effectively preventing damage to the gas cylinder or accidental breakage of the cylinder head valve body 8 caused by impacts from external hard objects during transportation, installation, or equipment vibration. This significantly improves the long-term reliability of the device in harsh environments.

[0056] In this application, the aforementioned puncture member 7 can be manually pressed down to move towards the second diaphragm 601 at the opening of the gas cylinder 6, thereby achieving the puncture action. To avoid accidental triggering, this application provides the following improvement.

[0057] like Figure 11 The figure shows a schematic diagram of a manual starting device 33 according to this application. As shown in the figure, a limiting insertion hole 707 is provided on the puncture guide rod 703 of the puncture member 7; after assembly, the limiting insertion hole 707 on the puncture guide rod 703 is located on the part that protrudes from the puncture guide sleeve. A detachable limiting member 708 is inserted into the limiting insertion hole 707. Figure 11 In this design, the limiting member 708 passes vertically through the limiting insertion hole 707. The limiting member 708 prevents the puncture member 7 from moving downwards, thereby avoiding accidental contact between the puncture member 7 and the second diaphragm 601 at the mouth of the gas cylinder 6. Since this design is manually triggered, the puncture return spring 11 can be omitted, and the puncture member 7 can be manually pressed down and lifted up. Alternatively, the puncture return spring 11 can be retained, and the puncture member 7 can be lifted upwards by the puncture return spring 11.

[0058] In a preferred embodiment, the puncture portion 701 of the puncture member 7 may also be provided with an exhaust channel or exhaust hole. For example... Figure 12 What is shown is Figure 11 A detailed structural diagram is shown. In the diagram, the outer surface of the puncture part 701 has a spiral groove 709 extending upwards from the bottom. The spiral groove 709 serves as an exhaust channel. When the puncture part 701 punctures the second diaphragm 601, high-pressure gas can be discharged along the spiral groove 709. This allows high-pressure gas to be discharged even without lifting the puncture member 7 upwards.

[0059] In a preferred embodiment, a pressing cap 710 may be provided at the top of the puncture guide rod 703 and above the limiting member 708 to facilitate quick and safe downward pressing of the puncture member 7.

[0060] The present application further provides an activation device with an auto-triggering structure that drives completion of the puncturing action. This automatic activation device 32 does not require manual triggering, and is disposed in the fire protection area 4 to automatically trigger when the temperature in the fire protection area 4 reaches the triggering temperature. As Figure 13 shown is a schematic diagram of the layout scheme of a fire extinguishing apparatus equipped with the automatic activation device 32 of the present application. The automatic activation device 32 is disposed in the fire protection area 4 covered by the spray pipeline 3.

[0061] As Figure 14 shown is an external appearance view of the automatic activation device 32 of the present application. Figure 15 is Figure 14 a view showing the internal structure after the external structure is cut open. From Figure 14 , Figure 15 it can be seen that the automatic activation device 32 is mainly provided with a cylindrical mounting shell 17 added above the aforementioned bottle head valve body 8; specifically, the bottom opening of the mounting shell 17 is provided with an internal thread, the bottle head valve body 8 is correspondingly provided with an external thread, and the mounting shell 17 is threadedly connected above the bottle head valve body 8. The interior of the mounting shell 17 is a cylindrical cavity, and a through hole is opened at the top. In addition, a U-shaped hanger 18 is further arranged at the top of the mounting shell 17.

[0062] A vertically movable impact hammer 19 is installed inside the mounting shell 17, as Figure 16 shown is a view showing the mounting structure of the impact hammer 19 of the present application. Figure 17 is Figure 16 a part drawing of the assembly structure of the impact hammer 19. The impact hammer 19 is composed of a cylindrical hammer head 1901 and a cylindrical hammer rod 1902; a energy storage spring 20 is sleeved on the hammer rod 1902. During assembly, the impact hammer 19 is inserted from the bottom opening of the mounting shell 17 and pushed to the deepest part of the mounting shell 17, the hammer rod 1902 of the impact hammer 19 passes through the through hole at the top of the mounting shell 17 and extends out of the top; the hammer rod 1902 is connected to the hanger 18 via a fusible member 21. After assembly, the impact hammer 19 is fixed in the mounting shell 17 by the fusible member 21, and the energy storage spring 20 is compressed by the hammer head 1901 in the deep part of the mounting shell 17. As Figure 14 shown, the fusible member 21 is exposed to the environment as a temperature sensing element. After the temperature in the fire protection area 4 fuses the fusible member 21, the energy storage spring 20 pushes the impact hammer 19 to strike the puncture member 7, so as to drive the puncture member 7 to pierce the second diaphragm 601 at the mouth of the gas storage cylinder 6.

[0063] The material of the fusible member 21 can be selected according to the fusing temperature, and the general working environment temperature is between 80°C and 100°C. It can be made of plastic, metal, fiber, etc., and the shape can be any shape such as sheet, rope, etc. As Figure 17As shown, in one optional embodiment of this application, the fuse 21 is a long, flat piece of brass alloy with a thickness of 1 mm and a melting temperature of 150℃±5℃. The fuse 21 melts when the ambient temperature reaches this melting temperature. In this application, the mounting shell 17, the hanger 18, the gas cylinder cover 15, the cylinder valve body 8, and the gas outlet pipe connector 14 are preferably made of brass alloy.

[0064] There are several ways to connect the fuse 21. For example, one end of the fuse 21 can be welded to the hammer rod 1902, and the other end can be welded to the hanger 18. The fuse 21 can also be connected using a detachable connection structure. Figure 17 As shown, the long, sheet-like fuse 21 has insertion pin holes 2101 at both ends. The crossbeam of the U-shaped hanger 18 has a vertically penetrating first slot 1801 and a front-to-back penetrating first pin hole 1802, which vertically passes through the first slot 1801. The hammer rod 1902 has an axially oriented second slot 1903 at its end, and a second pin hole 1904 passing through the second slot 1903. After assembly, the second slot 1903 is opposite to the first slot 1801. The second slot 1903 and the first slot 1801 shown in the figure are rectangular grooves. Insert the fuse 21 downwards into the hanger 18 from the first slot 1801, with the bottom of the fuse 21 inserted into the second slot 1903 at the end of the hammer rod 1902. The two pin holes 2101 on the fuse 21 are aligned with the first pin hole 1802 and the second pin hole 1904, respectively. Then, insert two cylindrical pins 22 into the first pin hole 1802 and the second pin hole 1904 to connect both ends of the fuse 21 to the hammer rod 1902 and the hanger 18, respectively. Figure 18 The diagram shown is a schematic diagram of the connection structure of the fuse 21 of this application.

[0065] In this application, the manual start device 33, together with the agent storage tank 1 and the sprinkler pipeline 3, constitutes a complete fire extinguishing system, such as Figure 1 As shown, the manual start device 33 is located outside the fire-resistant area 4, making it convenient for personnel to quickly pick up and operate the trigger device.

[0066] In this application, the automatic start-up device 32, together with the agent storage tank 1 and the sprinkler pipeline 3, constitutes a complete fire extinguishing system, such as Figure 13 As shown, an automatic activation device 32 is installed within the fire-protected zone 4. This device requires no manual triggering and automatically activates when the temperature of the fire-protected zone 4 reaches the trigger temperature. Of course, multiple automatic activation devices 32 can be installed, distributed in different locations within the fire-protected zone 4, especially at key monitoring points. Figure 19The diagram shows a fire extinguishing system with two automatic activation devices 32 as described in this application. The two automatic activation devices 32 are connected to a gas cylinder 6 via pipelines and a tee fitting. The fire extinguishing action can be initiated when either of the two automatic activation devices 32 is triggered.

[0067] In this application, the manual starting device 33 and the automatic starting device 32 can also be used in combination. For example... Figure 20 The diagram shows a fire extinguishing system with one manual activation device 33 and two automatic activation devices 32. This system can be manually activated while also having an automatic activation function, thus enhancing safety.

[0068] In one specific embodiment of this application, a pharmaceutical storage tank 1 that is easy to assemble and disassemble and can be repeatedly sealed and reused is also provided. Figure 21 The diagram shows the structure of a detachable medicine storage tank 1. In the diagram, the medicine storage tank 1 is cut open. A circular cap 101 is threaded onto the mouth of the medicine storage tank 1, and the cap 101 has two through holes. Figure 22 The image shown is a partial cross-sectional view of the bottle cap 101. A connecting sleeve 23 is installed in each of the two through holes. Figure 23 The diagram shows the structure of the connecting sleeve 23 after it has been cut open. The connecting sleeve 23 shown in the diagram has two sections with different diameters: the lower section 2301 has a larger diameter than the upper section 2302; furthermore, the lower section 2301 has a larger diameter than the through hole in the bottle cap 101, while the upper section 2302 has a smaller diameter than the through hole in the bottle cap 101. An annular outer step 2303 is formed on the outer side of the connection between the lower section 2301 and the upper section 2302. A fourth sealing ring 24 is installed on this outer step 2303. During assembly, the upper section 2302 extends through the through hole in the bottle cap 101 to the top of the bottle cap 101, and the outer step 2303 presses the fourth sealing ring 24 against the through hole in the bottle cap 101 from the inside to achieve a seal. The upper pipe section 2302 is provided with external threads on its outer side. The ends of the first guide pipe 2 and the second air guide pipe 5 are threadedly connected to the outside of the upper pipe section 2302 by a rotatable nut 25.

[0069] like Figure 23As shown, a cylindrical first receiving cavity 2304 is formed inside the lower pipe section 2301 of the connecting sleeve 23, and the sidewall of the first receiving cavity 2304 is provided with internal threads; a cylindrical second receiving cavity 2305 is formed inside the upper pipe section 2302, and the diameter of the second receiving cavity 2305 is smaller than the diameter of the lower first receiving cavity 2304, thereby forming an annular gasket limiting portion 2306 at the top of the first receiving cavity 2304. A circular first diaphragm 104 is placed in the first receiving cavity 2304, and the edge of the first diaphragm 104 is pressed against the gasket limiting portion 2306 at the top of the first receiving cavity 2304 by an annular gasket 26.

[0070] The portions of the two connecting sleeves 23 located inside the medicine storage tank 1 are respectively connected to the siphon pipe 105 and the first gas guide pipe 106. Figure 21 , Figure 22 In the example shown, a first air guide tube 106 is installed on the right connecting sleeve 23, and a siphon tube 105 is installed on the left connecting sleeve 23. Figure 22 As shown, the first air guide tube 106 is a rigid tube with an external thread at its upper end; the upper end of the first air guide tube 106 is threadedly connected to the first receiving cavity 2304 of the right connecting sleeve 23, and the upper end of the first air guide tube 106 presses on the annular gasket 26, thereby pressing the edge of the first diaphragm 104 onto the gasket limiting part 2306 at the top of the first receiving cavity 2304.

[0071] like Figure 21 As shown, the left siphon tube 105 is an assembly of several parts, including a rigid connecting tube 27, a flexible tube 28, and a tube head 29. The upper end of the rigid connecting tube 27 is threaded and threaded onto the left connecting sleeve 23. The rigid connecting tube 27 is connected in the same way as the first air guide tube 106, also pressing against a first diaphragm 104. The lower end of the rigid connecting tube 27 is connected to one end of the flexible tube 28 via a clamp 30, and the other end of the flexible tube 28 is connected to the tube head 29 via a clamp 30. The tube head 29 is made of a heavy metal tube, and a section of rubber tubing 31 is fitted onto the end of the tube head 29. Because the flexible tube 28 is flexible and the tube head 29 is heavy, regardless of whether the medicine storage tank 1 is placed vertically or horizontally (… Figure 3 As shown), the pipe head 29 can be submerged to the bottom of the extinguishing agent, allowing most of the extinguishing agent in the agent storage tank 1 to be discharged through the siphon pipe 105.

[0072] Furthermore, in one specific embodiment of this application, the extinguishing agent storage tank 1 is a stainless steel cylinder with a capacity of 8 kg, directly filled with extinguishing agent. The gas cylinder 6 stores 33 grams of carbon dioxide. When the ambient temperature reaches a preset value, the pressure in the gas cylinder 6 can reach 15 MPa. After the carbon dioxide expands, its volume exceeds that of the 8 kg extinguishing agent storage tank 1, and its pressure is not lower than 0.8 MPa. Testing shows that under this scheme, the remaining amount of extinguishing agent in the extinguishing agent storage tank 1 is less than 0.3 kg, and the initial pressure of the extinguishing agent injection is 12 MPa.

[0073] Furthermore, the second gas guide pipe 5 can be a PTFE hose with an inner diameter of 6 mm and a length of 2 meters; the first guide pipe 2 has an inner diameter of 10 mm and a length of 3 meters; under this scheme, the nozzle flow rate on the spray pipeline 3 is 0.5 liters per second. The smaller 6 mm PTFE drive pipe can minimize the throttling loss of high-pressure gas, instantly transmitting the initial 15 MPa pressure to the agent storage tank 1 (generating an initial injection high pressure of 12 MPa); while the larger 10 mm agent pipeline ensures that the flow resistance of the extinguishing agent is minimal within a 3-meter transmission distance, enabling the instantaneous formation of a high-flow-rate atomized spray.

[0074] With a terminal thrust of 0.8 MPa, and in conjunction with the inclined siphon pipe 105 at the bottom, the system achieves an extremely high discharge rate. The final amount of extinguishing agent residue in the agent storage tank 1 is far less than 0.3 kg (residual rate less than 3.75%), solving the industry problem of high residual rate in direct-push systems.

[0075] The working principle of the non-pressurized water-based fire extinguishing device described in this application is as follows: Before activation, the agent storage tank 1 is in a closed state (standby state). When the piercing element 7 in the activation device is subjected to external force, it punctures the second diaphragm 601 at the mouth of the gas cylinder 6. High-pressure gas from the gas cylinder 6 is ejected from the puncture in the second diaphragm 601, travels through the second air guide pipe 5 to the air inlet 102 on the agent storage tank 1, punctures the first diaphragm 104 on the air inlet 102, and finally enters the agent storage tank 1. As the pressure inside the agent storage tank 1 increases, the fire extinguishing agent inside the agent storage tank 1 is forced to puncture the first diaphragm 104 on the fire extinguishing agent outlet 103 and is ejected. The fire extinguishing agent is transported to the fire-protected area 4 via the first guide pipe 2 and the spray pipe 3, and finally sprayed out from the spray pipe 3 to extinguish the fire in the fire-protected area 4. This device is suitable for fire prevention in the field of new energy storage, such as fire prevention for equipment like energy storage battery boxes and battery module compartments. Suitable for fire protection in the power distribution network field, such as fire protection of high and low voltage distribution cabinets, ring main units, transformer enclosures and other equipment; suitable for fire protection in the communication infrastructure field, such as fire protection of 5G base station cabinets, data center cabinets, unattended computer rooms and other equipment; suitable for special industries, such as fire protection of mining electrical equipment, explosion-proof cabinets in chemical plants and other equipment.
