Description

Technical Field

[0001] This invention belongs to the field of fire extinguishing technology, specifically relating to a multifunctional fire extinguishing device for fire extinguishing and emergency response. Background Technology

[0002] Among various disasters, fires occur most frequently and are one of the major threats to personal safety and social development. When a fire occurs, taking appropriate measures to deal with the situation can promptly control its spread, thereby preventing larger-scale fires and minimizing the losses caused by the fire. Common firefighting methods include the following.

[0003] Fine water mist fire suppression primarily uses water as the extinguishing medium. High-pressure water pumps and specially designed nozzles disperse water into fine droplets. The evaporation of the fine water mist causes efficient cooling and oxygen depletion, thus extinguishing the fire. The application of fine water mist fire suppression technology is largely unrestricted by the fire scenario and can be used to handle fires involving solid, oil, and gaseous fuels.

[0004] Chemical suppressant fire suppression is a method that uses chemical means to inhibit fire and ultimately extinguish it. Its core principle is to utilize chemical suppressants to react with free radicals generated during combustion, thereby interrupting the combustion chain reaction and preventing the fire from spreading and continuing the combustion process.

[0005] Metastable activated water fire extinguishing utilizes activated water (also known as temperature-activated water), a mixture of steam and water droplets. It is obtained by the instantaneous transformation of underheated water to boiling point (within 10⁻⁹ to 10⁻⁴ seconds). Due to high pressure, the water does not boil, entering a metastable state and subsequently undergoing explosive boiling. Activated water droplets, in a metastable state, undergo physicochemical changes different from ordinary water, such as alterations in oxidation-recovery potential, viscosity, and capacitance. This gives activated water excellent smoke settling properties or enhances the gas melting process, offering advantages in fire extinguishing efficiency and environmental friendliness.

[0006] However, the existing technical equipment (firefighting and rescue) in firefighting equipment is low-power and inefficient, and cannot meet the actual needs of the diversity of specific fire extinguishing methods. It is necessary to mobilize a large number of technical equipment from the fire department's equipment inventory.

[0007] In view of this, there is an urgent need for a multi-functional fire extinguishing device that can effectively solve the drawbacks of the single fire extinguishing method of fire-fighting equipment, enable flexible switching and integration of fire extinguishing methods, and dynamically adjust the fire extinguishing operation parameters according to the actual needs of fire extinguishing, thereby improving fire extinguishing efficiency while ensuring the safety of operators. Summary of the Invention

[0008] To address the aforementioned technical problems, this invention provides a multifunctional fire extinguishing device that effectively solves the drawback of single fire extinguishing methods in fire-fighting equipment. It enables flexible switching and integration of fire extinguishing methods and can dynamically adjust fire extinguishing operation parameters according to actual fire extinguishing needs, thereby improving fire extinguishing efficiency while ensuring the safety of operators.

[0009] To achieve the above objectives, the technical solution of this invention is implemented as follows:

[0010] A multifunctional fire extinguishing device includes a water storage tank, a storage tank, a first pipeline, a second pipeline, and a third pipeline. The inlet end of the first pipeline is connected to the water storage tank, and the outlet end of the first pipeline is connected to a spray device, forming a first passage for fire extinguishing. The inlet end of the second pipeline is connected to the storage tank, and the outlet end of the second pipeline is disconnectably connected to the outlet end of the first pipeline, forming a second passage for fire extinguishing. The inlet end of the third pipeline is disconnectably connected to the inlet end of the first pipeline, and the outlet end of the third pipeline is connected to a spray device, forming a third passage for fire extinguishing. The outlet end of the second pipeline... The outlet end of the pipe is connected to the outlet end of the third pipe via a disconnectable connection, forming a mixed passage that combines the second and third passages. The first passage, formed by the first pipe connected to the water storage tank, can provide a water-based fire extinguishing mode. The second pipe, which is connected to the storage tank at one end and disconnected from the first pipe at the other end, can inject the extinguishing agent from the storage tank into the first pipe as needed, thereby forming a new extinguishing agent that is a mixture of water and extinguishing agents of different properties in the storage tank, or the extinguishing agent in the storage tank can be sprayed out separately, forming a fire extinguishing channel that can operate independently or separately with the extinguishing agent in the storage tank.

[0011] Furthermore, the first pipeline includes a first pipeline valve, a first pipeline filter, and a first pipeline pump that are connected in a continuous manner. One end of the first pipeline valve is connected to a water storage tank via a pipe, and the other end of the valve is connected to the inlet end of the first pipeline pump via the first pipeline filter. The outlet end of the first pipeline pump is connected to the outside.

[0012] Furthermore, the second pipeline includes a second pipeline pump, a second pipeline valve group, and a second pipeline regulating valve. The inlet end of the second pipeline pump is connected to the storage tank, and the outlet end of the second pipeline pump is connected to the first pipeline in a cut-off manner through the second pipeline valve group. The second pipeline regulating valve is located between the second pipeline pump and the second pipeline valve group, and the flow surface of the connecting pipe to the second pipeline is adjustable.

[0013] Furthermore, the second pipeline valve group includes a first valve and a second valve, wherein the inlet end of the first valve is connected to the storage tank, and the outlet end of the second valve is connected to the inlet end of the second pipeline pump; the inlet end of the second valve is connected to the outlet end of the second pipeline regulating valve, and the outlet end of the second valve is connected to the first pipeline.

[0014] Furthermore, the second pipeline also includes a second flow meter installed on the connecting pipe of the second pipeline, and the second flow meter is installed at the outlet end of the regulating valve of the second pipeline.

[0015] Furthermore, the third pipeline includes a third pipeline pump, a third heater, a third pipeline valve group, and a check valve, wherein the inlet end of the third pipeline pump is connected to the first pipeline in a shut-off manner; the outlet end of the third pipeline pump is connected to the inlet end of the third heater through the third pipeline valve group; and the outlet end of the third heater is connected to an external injection device through the check valve.

[0016] Furthermore, the third pipeline valve group includes a third regulating valve, a fourth regulating valve, and a fifth regulating valve. The inlet end of the third regulating valve is connected to the outlet end of the third pipeline pump, and the outlet end of the third regulating valve is connected to the inlet end of the third heater through the fourth regulating valve. The inlet end of the fifth regulating valve is connected to the outlet end of the third heater, and the outlet end of the fifth regulating valve is connected to a check valve.

[0017] Furthermore, the third pipeline valve group also includes a sixth regulating valve, one end of which is connected to the outlet end of the third heater, and the other end of which is connected to the water storage tank.

[0018] Furthermore, the third pipeline valve group also includes a seventh regulating valve arranged in parallel with the sixth regulating valve. One end of the seventh regulating valve is connected to the outlet end of the fifth regulating valve, and the other end is connected to the water storage tank.

[0019] Furthermore, it also includes a third pipeline flow meter installed on the connecting pipe of the third pipeline. The third pipeline flow meter includes a first flow meter and a third flow meter, wherein the first flow meter is installed on the inlet end side of the third heater; and the third flow meter is installed on the outlet end side of the one-way valve.

[0020] The multifunctional fire extinguishing device provided in the above embodiments can provide a water-based fire extinguishing mode through a first passage formed by a first pipeline connected to a water storage tank. Through a second pipeline connected at one end to the storage tank and at the opposite end to the first pipeline (which can be disconnected), fire extinguishing agents from the storage tank can be injected into the first pipeline as needed, thereby forming a new fire extinguishing agent mixture of water and fire extinguishing agents of different properties in the storage tank. Alternatively, the fire extinguishing agent from the storage tank can be sprayed separately, forming a separate fire extinguishing channel that allows the fire extinguishing agent in the storage tank to operate independently. For example, chemical inhibitors. Meanwhile, a third pipeline, with one end detachably connected to the first pipeline and the other end connected to the water storage tank, can treat the water flowing through the first pipeline in the storage tank. This alters the physical state of the water in the storage tank, thereby enabling different fire extinguishing modes under different physical states. This allows for flexible selection of fire extinguishing modes for water under different physical states, as well as the individual and / or mixed extinguishing agents to form new extinguishing agents. This effectively addresses the limitation of single extinguishing methods in existing vehicle-mounted fire extinguishing devices. It dynamically adjusts the extinguishing agent dosage according to the actual fire situation, improving extinguishing efficiency while ensuring operator safety. The pump in the first pipeline disperses liquid water into fine droplets, increasing the surface area of ​​contact between the droplets and flames / heat sources, thus enhancing cooling and reducing water consumption. Furthermore, by setting up… A first pipeline valve assembly, connected to and maintaining communication with the first pipeline, enables precise control of flow and pressure within the first pipeline's connecting pipe. A first pipeline flow meter, positioned between the hose reel and the first pipeline pump, provides real-time monitoring of the flow rate in the connecting pipe. Under the action of the second pipeline pump, the extinguishing agent in the storage tank, through the combined action of the second pipeline valve assembly and the second management regulating valve, achieves a fire extinguishing mode where different types of extinguishing agents are mixed and / or work together. A second pipeline regulating valve, with an adjustable flow surface connected to the connecting pipe of the second pipeline, allows for flexible and precise automatic adjustment of its opening, enabling accurate control of parameters such as flow rate, pressure, and level of the extinguishing agent entering the first pipeline from the storage tank, ensuring a stable mixing ratio between the extinguishing agent in the storage tank and the extinguishing agent in the water tank.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0023] It should be noted that if the embodiments of the present invention involve directional indications, such as up, down, left, right, front, back, etc., these directional indications are only used to explain the relative positional relationships and movement of the components in a specific posture. If the specific posture changes, the directional indications will also change accordingly. Furthermore, if the embodiments of the present invention involve descriptions such as "first," "second," "S1," "S2," "step one," "step two," etc., these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance, or implicitly indicating the number of technical features indicated or the order of method execution. Those skilled in the art will understand that anything that does not violate the inventive concept and is within the scope of the present invention should be included in the protection scope of the present invention.

[0024] like Figure 1As shown in the figure, a multifunctional fire extinguishing device according to a partially exemplary embodiment includes a water storage tank 100, a storage tank 200, a first pipeline 10, a second pipeline 20, and a third pipeline 30. The inlet end of the first pipeline 10 is connected to the water storage tank 100, and the outlet end of the first pipeline 10 is externally connected to a spray device (not shown in the figure), forming a first passage for fire extinguishing. The inlet end of the second pipeline 20 is connected to the storage tank 200, and the inlet end of the second pipeline 20 is disconnectably connected to the outlet end of the first pipeline 10, forming a second passage for fire extinguishing. The inlet end of the third pipeline 30 is disconnectably connected to the inlet end of the first pipeline 10, and the outlet end of the third pipeline 30 is externally connected to a spray device (not shown in the figure). (As shown), a third passage is formed that can be used for fire extinguishing; the outlet end of the second pipe 20 is connected to the outlet end of the third pipe 30 via a connecting pipe that can be disconnected, forming a mixing passage that combines the second and third passages; thus, the first passage formed by the first pipe connected to the water storage tank can provide a water-based fire extinguishing mode; by connecting the second pipe, one end of which is connected to the storage tank and the other end of which is disconnected from the first pipe, the fire extinguishing agent in the storage tank can be injected into the first pipe as needed, thereby forming a new fire extinguishing agent that mixes water with fire extinguishing agents of different properties in the storage tank, or the fire extinguishing agent in the storage tank can be sprayed out separately, forming a separate fire extinguishing passage that can operate the fire extinguishing agent in the storage tank independently. For example, chemical inhibitors. Meanwhile, a third pipeline, with one end disconnectable from the first pipeline and the other end connected to the water storage tank, can treat the water flowing through the first pipeline in the storage tank, changing the water's physical state and thus enabling different fire extinguishing modes under different physical conditions. This allows for flexible selection of fire extinguishing modes for water under different physical conditions, as well as the individual and / or mixed fire extinguishing agents to form new fire extinguishing agents. This effectively solves the drawback of the single fire extinguishing mode in existing vehicle-mounted fire extinguishing devices, enabling flexible switching and integration of fire extinguishing modes. Furthermore, it can dynamically adjust fire extinguishing operation parameters according to actual fire extinguishing needs, improving fire extinguishing efficiency while ensuring the safety of operators.

[0025] Optionally, after the second pipeline 20 is connected to the storage tank 200, its other end is connected to the outlet end of the first pipeline 10. This reduces the damage to the first pipeline caused by different extinguishing agents, while accurately controlling the proportion of components in the storage tank and the first pipeline. This enables multiple extinguishing modes of superimposing or mixing different types of extinguishing agents, and ensures that the mixing ratio remains stable, which will significantly improve the extinguishing effect.

[0026] In the embodiments of this application, such as Figure 1As shown, the first pipeline 10 includes a first pipeline valve 11, a first pipeline filter 12, and a first pipeline pump 13, all connected in a continuous manner. One end of the first pipeline valve 11 is connected to the water storage tank 100 via a pipe, and the other end is connected to the inlet end of the first pipeline pump 13 via the first pipeline filter 12. The outlet end of the first pipeline pump 13 is connected to the outside environment. Furthermore, the first pipeline pump is a high-pressure pump. Thus, water in the water storage tank 100, driven by the first pipeline pump 13, flows through the first pipeline valve 11 and the first pipeline filter 12, achieving connection with the outside environment, such as a spray device or a handheld nozzle. This allows the water in the water storage tank 100 to be dispersed into fine water droplets under the action of the first pipeline pump 13, thereby increasing the surface area of ​​the water droplets in contact with the flame or heat source, enhancing the cooling effect, and reducing water consumption.

[0027] Optionally, to achieve precise control of the flow rate and pressure in the connecting pipe of the first pipeline 10, a first pipeline valve group 14 is further included, which is disposed on the connecting pipe of the first pipeline 10 and connected to the connecting pipe of the first pipeline 10. Preferably, the first pipeline valve group 14 includes a first regulating valve 141 and a second regulating valve 142, wherein the first regulating valve 141 is disposed between the water storage tank 100 and the first pipeline filter 12, and the second regulating valve 142 is disposed at the outlet end of the first pipeline pump 13.

[0028] Optionally, it also includes a first sensor 15 connected to the connecting pipe of the first pipeline 10. Specifically, the first pipeline sensor 15 is located at the outlet end of the first pipeline pump 13, thereby enabling accurate measurement of parameters at the outlet end of the first pipeline pump. For example, if the first pipeline sensor 15 is selected as a pressure sensor, it can realize real-time detection of the pressure in the connecting pipe at the outlet end of the first pipeline pump 13.

[0029] Optionally, to broaden the applicability of the fire extinguishing device, a hose reel 17 is also included, which is located at the outlet end of the first pipeline pump 13 and connected to the first pipeline pump 13. Thus, the hose reel can be used to neatly and effectively store and release the hose that is connected to the first pipeline.

[0030] Optionally, to facilitate real-time monitoring of the flow rate in the first pipeline 10, a first pipeline flow meter 16 is also included, which is disposed between the hose reel 17 and the first pipeline pump 13.

[0031] In summary, the first pipeline provided in this application, connected to the water storage tank, disperses liquid water into fine droplets under the action of the first pipeline pump, thereby increasing the surface area of ​​the droplets in contact with the flame and heat source, thus enhancing the cooling effect and reducing water consumption; the first pipeline valve group, installed on the connecting pipe of the first pipeline and connected to it, enables precise control of the flow and pressure in the connecting pipe of the first pipeline; and the first pipeline flow meter, installed between the hose reel and the first pipeline pump, enables real-time monitoring of the flow in the connecting pipe of the first pipeline.

[0032] In the embodiments of this application, such as Figure 1 As shown, the second pipeline 20 includes a second pipeline pump 21, a second pipeline valve group 22, and a second pipeline regulating valve 23. The inlet end of the second pipeline pump 21 is connected to the storage tank 200, and the outlet end of the second pipeline pump 21 is connected to the first pipeline 10 via the second pipeline valve group 22 in a cut-off manner. The second pipeline regulating valve 23 is located between the second pipeline pump 21 and the second pipeline valve group 22, and its flow surface in the connecting pipe to the second pipeline 20 is adjustable. Therefore, under the action of the second pipeline pump 21, the extinguishing agent in the storage tank 200 flows through the second pipeline... Under the combined action of the first pipeline valve group and the second management regulating valve 23, extinguishing agents can be injected into the first pipeline 10 as needed, achieving a fire extinguishing mode of mixing and / or synergistic action of different types of extinguishing agents. The second pipeline regulating valve 23, which is adjustable in flow area to the connecting pipe of the second pipeline 20, can flexibly and precisely adjust its opening automatically, achieving precise control over parameters such as the flow rate, pressure, and liquid level of the extinguishing agent entering the first pipeline 10 from the storage tank 200, ensuring a stable mixing ratio of the extinguishing agent in the storage tank 200 and the extinguishing agent in the water storage tank 100.

[0033] Optionally, the second pipeline valve group 22 includes a first valve 221 and a second valve 222. The inlet end of the first valve 221 is connected to the storage tank 200, and the outlet end of the second valve 221 is connected to the inlet end of the second pipeline pump 21. The inlet end of the second valve 222 is connected to the outlet end of the second pipeline regulating valve 23, and the outlet end of the second valve 222 is connected to the first pipeline 10. Preferably, the outlet end of the second valve 222 is located between the first pipeline flow meter 16 and the hose reel 17. Thus, the first valve can be used to effectively control whether the fire extinguishing agent is introduced into the storage tank, and the second valve can be used to conveniently control whether the fire extinguishing agent in the storage tank is mixed with the fire extinguishing agent in the water tank.

[0034] Preferably, to expand the fire extinguishing modes and improve fire extinguishing efficiency, a third valve 223 is also included at the distal end of a branch connected to the outlet end of the second pipeline regulating valve 23. Specifically, the inlet end of the third valve 223 is connected to the outlet end of the second pipeline regulating valve 23, and the outlet end of the third valve 223 is connected to the outlet end of the third pipeline 30. Thus, by injecting the extinguishing agent inside the storage tank into the outlet end of the third pipeline through the third valve, the fire extinguishing efficiency of the third pipeline is further improved.

[0035] Furthermore, in order to ensure the safety of the internal connection of the second pipeline 20 and to improve the convenience of cleaning the second pipeline 20, a fourth valve 224 is also provided between the first valve 221 and the second pipeline pump 21. The inlet of the fourth valve 224 is connected to the outlet end of the first valve 221, and the outlet end of the fourth valve 224 is provided to be sealed and openable to the outside.

[0036] Optionally, to facilitate precise monitoring of the dosage of extinguishing agent in the storage tank 200 in the second pipeline, and to achieve more accurate and stable mixing, a second flow meter 24 is also included on the connecting pipe of the second pipeline 20. Specifically, the second flow meter 24 is located at the outlet end of the second pipeline regulating valve 23.

[0037] In summary, the second pipeline provided in this application, connected to the storage tank, allows the extinguishing agent in the storage tank to achieve a fire extinguishing mode where different types of extinguishing agents mix and / or work together, under the action of the second pipeline pump and the combined action of the second pipeline valve group and the second management regulating valve. Furthermore, the adjustable second pipeline regulating valve, connected to the flow surface of the connecting pipe, allows for flexible and precise automatic adjustment of its opening, enabling accurate control of parameters such as the flow rate, pressure, and liquid level of the extinguishing agent entering the first pipeline from the storage tank. This ensures a stable mixing ratio of the extinguishing agent in the storage tank and the extinguishing agent in the water storage tank.

[0038] In the embodiments of this application, such as Figure 1 As shown, the third pipeline 30 includes a third pipeline pump 31, a third heater 32, a third pipeline valve group 33, and a one-way valve 35. The inlet end of the third pipeline pump 31 is connected to the first pipeline 10 in a shut-off manner; the outlet end of the third pipeline pump 31 is connected to the inlet end of the third heater 32 through the third pipeline valve group 33; the outlet end of the third heater 32 is connected to an external spray device (not shown in the figure) through the one-way valve 35. Thus, water in the water storage tank 100 enters the third heater 32 under the action of the third pipeline pump 31, thereby heating the liquid water into water vapor, which then enters the spray device through the one-way valve 35. This fully utilizes the characteristic that the latent heat of vaporization of hot water is faster than that of cold water, thereby improving the efficiency of fire extinguishing.

[0039] Optionally, the third pipeline valve group 33 includes a third regulating valve 331, a fourth regulating valve 332, and a fifth regulating valve 333. The inlet end of the third regulating valve 331 is connected to the outlet end of the third pipeline pump 31, and the outlet end of the third regulating valve 331 is connected to the inlet end of the third heater 32 via the fourth regulating valve 332. The inlet end of the fifth regulating valve 333 is connected to the outlet end of the third heater 32, and the outlet end of the fifth regulating valve 333 is connected to the check valve 35. Thus, by regulating the third regulating valve 331 added to the outlet end of the third pipeline pump 31, the third pipeline 333 can achieve... The device switches between connected and disconnected modes to allow for connection to the first pipeline 10 and the third pipeline 30. This enables switching between fire extinguishing methods using a fine mist water mixture as the extinguishing agent and a nano-water extinguishing mode using high-temperature water vapor. This allows for changes in the different physical states of water in the storage tank, enabling flexible selection of extinguishing modes for water under different physical states, as well as extinguishing modes for different extinguishing agents individually and / or mixed with water to form new extinguishing agents. This effectively solves the drawback of the single extinguishing mode in existing vehicle-mounted fire extinguishing devices, improving fire extinguishing efficiency while ensuring the safety of operators.

[0040] Optionally, in order to reduce the operating load of the third heater 32 and improve the operational stability of the third pipeline 30, the third pipeline valve group 33 further includes a sixth regulating valve 334, one end of which is connected to the outlet end of the third heater 32 and the other end of which is connected to the water storage tank 100. Preferably, the inlet end of the sixth regulating valve 334 is connected to the outlet end of the fifth regulating valve 333, and the other end of which is connected to the water storage tank 100. Thus, when the operating pressure of the third pipeline 30 is too high, the sixth regulating valve 334 will return some of the heated water to the water storage tank 100, thereby increasing the temperature of the water entering the third heater 32, thereby reducing the instantaneous power of the third heater 32 and ensuring the stability and safety of the operation of the third pipeline 30.

[0041] Furthermore, in order to improve the utilization rate of the heated heat, when the fifth regulating valve 333 located at the outlet end of the third heater 32 is fully open and the temperature inside the connecting pipe is still too high, the third pipeline valve group 33 also includes a seventh regulating valve 335 connected in parallel with the sixth regulating valve 334. One end of the seventh regulating valve 335 is connected to the outlet end of the fifth regulating valve 333, and the other end is connected to the water storage tank 100.

[0042] Optionally, the third pipeline valve group 33 also includes an eighth regulating valve 336 disposed on the outlet end of the one-way valve 35. The inlet of the eighth regulating valve 336 is connected to the outlet end of the one-way valve 35, and the outlet of the eighth regulating valve 336 is connected to an external spraying device (not shown in the figure). Thus, by regulating the eighth regulating valve 336, the dosage of the fire extinguishing agent sprayed in the third pipeline 30 can be precisely controlled.

[0043] In addition, to ensure the safety of the third pipeline 30 during operation, the third pipeline valve group 33 also includes a ninth regulating valve 337 disposed between the third heater 32 and the fifth regulating valve 333. One end of the ninth regulating valve 337 is connected to the outlet end of the third heater 32, and the other end is open and closed.

[0044] Optionally, to achieve real-time temperature monitoring in the connecting pipes of the third pipeline 30 and improve the sensitivity of temperature control during the operation of the third pipeline 30, a temperature monitoring unit 34 is also included, which is electrically linked to the third pipeline pump, the third heater 32, and the third pipeline valve group 33. Specifically, the temperature monitoring unit 34 includes a first temperature sensor 341, a second temperature sensor 342, and a third temperature sensor 343. The first temperature sensor 341 is located at the outlet end of the third heater 32, the second temperature sensor 342 is located at the outlet end of the fifth regulating valve 333, and the third temperature sensor 343 is located at the outlet end of the water storage tank 100. Specifically, to improve the sensitivity and accuracy of monitoring, the first temperature sensor 341 is located between the third heater 32 and the fifth regulating valve 333, the second temperature sensor 342 is located between the fifth regulating valve 333 and the one-way valve 35, and the third temperature sensor 343 is located between the first pipeline valve 11 and the water storage tank 100. Therefore, by using the temperature monitoring unit on the connecting pipe of the third pipeline 30, the temperature changes in the connecting pipe of the third pipeline 30 can be captured in a timely manner. Then, the computer's optimization algorithm control, such as the control of the third heater 32 through PID method, ensures that the temperature control in the third pipeline 30 is always at the optimal edge. While ensuring the safety of the third heater 32, the energy consumption of operation can be effectively reduced.

[0045] Optionally, after the outlet end of the ninth regulating valve 336 is connected to the outlet end of the third valve 223, an external spraying device (not shown in the figure) is connected. Thus, the water in the storage tank 100, after passing through the third heater 32 to form water vapor, passes through the one-way valve 35 and is then thoroughly mixed with the extinguishing agent injected into the storage tank 200 by the outlet end of the ninth regulating valve 336 and the outlet end of the third valve 223. This achieves a dual superposition of different extinguishing modes, resulting in more efficient extinguishing performance and shortening the extinguishing time. For example, by turning the water in the storage tank 100 into pressure-stable active water after passing through the third heater 32, and then mixing it with the chemical inhibitor in the storage tank 200, a extinguishing medium with higher extinguishing efficiency can be obtained.

[0046] Preferably, to achieve precise control of each valve in the third pipeline 30, a third pipeline flow meter 36 is also included, which is installed on the connecting pipe of the third pipeline 30. Specifically, the third pipeline flow meter 36 includes a first flow meter 361 and a third flow meter 362. The first flow meter 361 is installed at the inlet end of the third heater 32, and the third flow meter 362 is installed at the outlet end of the one-way valve 35. Thus, by using the first flow meter 361 installed at the inlet end of the third heater 32, when the third pipeline 30 is the main fire extinguishing channel, the flow rate entering the third heater 32 can be monitored, and it can be linked with the monitoring system of the third pipeline 30 to ensure that the water flow rate is at the optimal flow rate for fire extinguishing effect. For example, when extinguishing a fire solely through the third pipeline 30, the flow rate entering the third heater 32 is always controlled to be greater than 100 L / min to ensure the best fire extinguishing effect. By using the third flow meter 362 installed at the outlet end of the one-way valve 35, the flow rate at the outlet end of the one-way valve 35 can be monitored. In conjunction with the second flow meter 24, while the second valve 222 is closed, the flow rate of the extinguishing agent in the storage tank 200 and the extinguishing medium flowing through the one-way valve 35 can be ensured, thereby ensuring that the mixing ratio of the two remains stable to obtain the optimal fire extinguishing performance.

[0047] In addition, to ensure the safety of the third heater 32, a third solenoid valve 37 is also included, which is connected to the third heater 32 at one end and can be opened at the other end.

[0048] In summary, by using a third pipeline pump connected to the first pipeline in a cut-off manner, water from the storage tank is transported to the third heater, where the liquid water is heated into steam. This steam then enters the spray device via a one-way valve, fully utilizing the faster latent heat of vaporization of hot water compared to cold water to improve fire extinguishing efficiency. Furthermore, by adjusting the third regulating valve at the outlet of the third pipeline pump, the third pipeline can be switched between connected and cut-off states, allowing for selection between the first and third pipelines. This enables switching between extinguishing methods using a fine mist water mixture as the extinguishing agent and using high-temperature steam nano-water extinguishing methods. This allows for changes in the physical state of the water in the storage tank, enabling flexible selection of extinguishing modes based on different physical states of water, as well as different extinguishing agents used individually or in mixtures with water to form new extinguishing agents. This effectively addresses the limitation of single extinguishing methods in existing vehicle-mounted fire extinguishing devices, improving fire extinguishing efficiency while ensuring operator safety.

[0049] In the embodiments of this application, such as Figure 1 As shown, to achieve rapid water replenishment of the water storage tank 100, a fourth pipeline 40 is included, with one end connected to the water storage tank 100 and the other end connected to the submersible pump 300 and / or fire hydrant 400. Specifically, the fourth pipeline 40 includes a fourth pipeline solenoid valve 41 and a fourth pipeline regulating valve 42 connected in series. The inlet end of the fourth pipeline solenoid valve 41 is connected to the submersible pump 300, and the outlet end of the fourth pipeline solenoid valve 41 is connected to the inlet end of the fourth pipeline regulating valve 42. The distal end of the inlet end of the fourth pipeline solenoid valve 41 is connected to the fire hydrant 400, and the outlet end of the fourth pipeline solenoid valve 41 is connected to the water storage tank 100. Thus, through the connected fourth pipeline solenoid valve and fourth pipeline regulating valve, connection to the submersible pump and fire hydrant is achieved very conveniently, thereby enabling rapid water replenishment of the water storage tank.

[0050] Optionally, in order to improve operational safety and reduce the failure rate of the system, a fourth pipeline filter 43 is also included, which is installed on the connecting pipe of the fourth pipeline 40. The fourth pipeline filter 43 is installed between the fourth pipeline solenoid valve 41 and the fourth pipeline regulating valve 42 to ensure effective preliminary treatment of the water entering the water storage tank 100.

[0051] Optionally, it also includes a fourth pipeline sensor 44 located on the connecting pipe of the fourth pipeline 40, between the fourth pipeline regulating valve 42 and the fourth pipeline filter 43. The fourth pipeline sensor 44 is electrically connected to the control system, thereby automatically adjusting the valve opening of the fourth pipeline regulating valve 42 by detecting the pressure in the connecting pipe at the inlet end of the fourth pipeline regulating valve 42, thus ensuring the safety of the entire fire extinguishing device.

[0052] Optionally, to ensure the reliability, stability, and continuity of the entire fire extinguishing system, a liquid level sensor 45 is also included, which is installed inside the water storage tank 100 and electrically connected to the control system. Thus, by installing the liquid level sensor in the water storage tank, it is possible to monitor in real time whether the liquid level in the water storage tank is too low. If the liquid level exceeds the preset minimum water level value, an alarm device will be automatically triggered to remind the staff to perform the water filling procedure.

[0053] In summary, the fourth pipeline provided in this application, through the connection of the fourth pipeline solenoid valve and the fourth pipeline regulating valve, can be conveniently connected to the submersible pump and fire hydrant, thereby enabling rapid replenishment of water to the storage tank; the filter installed on the connecting pipe of the fourth pipeline ensures effective preliminary treatment of the water entering the storage tank, improving operational safety and reducing the system failure rate; the liquid level sensor installed in the storage tank can monitor in real time whether the liquid level in the storage tank is too low. If it exceeds the preset minimum water level value, an alarm device will be automatically triggered to remind the staff to perform the water replenishment procedure.

[0054] Furthermore, the aforementioned regulating valve is an electric regulating valve. The specific structure or model of the electric regulating valve, as well as the specific path, principle, or other structural shape for signal transmission and control to achieve the same function, should be easily conceived by those skilled in the art, and therefore will not be elaborated here.

[0055] In addition, it includes a control system for controlling the entire system, electrically connected to each sensor, and wired and other auxiliary equipment for connection. For example, control switches, etc., should be readily conceived by those skilled in the art, and therefore will not be described in detail here.

[0056] The multi-functional fire extinguisher provided in the above embodiments of this application has at least the following characteristics:

[0057] The multifunctional fire extinguisher provided in this embodiment can provide a water-based fire extinguishing mode through a first passage formed by a first pipeline connected to a water storage tank. A second pipeline, with one end connected to the storage tank and the other end disconnected from the first pipeline, allows the extinguishing agent from the storage tank to be injected into the first pipeline as needed, forming a new extinguishing agent mixture of water and extinguishing agents of different properties in the storage tank. Alternatively, the extinguishing agent from the storage tank can be sprayed separately, forming a separate fire extinguishing channel for the extinguishing agent in the storage tank to operate independently. For example, chemical inhibitors. Meanwhile, a third pipeline, with one end detachably connected to the first pipeline and the other end connected to the water storage tank, can treat the water flowing through the first pipeline in the storage tank. This alters the physical state of the water in the storage tank, thereby enabling different fire extinguishing modes under different physical states. This allows for flexible selection of fire extinguishing modes for water under different physical states, as well as the individual and / or mixed extinguishing agents to form new extinguishing agents. This effectively addresses the limitation of single extinguishing methods in existing vehicle-mounted fire extinguishing devices. It dynamically adjusts the extinguishing agent dosage according to the actual fire situation, improving extinguishing efficiency while ensuring operator safety. The pump in the first pipeline disperses liquid water into fine droplets, increasing the surface area of ​​contact between the droplets and flames / heat sources, thus enhancing cooling and reducing water consumption. Furthermore, by setting up… A first pipeline valve assembly, connected to and maintaining communication with the first pipeline, enables precise control of flow and pressure within the first pipeline's connecting pipe. A first pipeline flow meter, positioned between the hose reel and the first pipeline pump, provides real-time monitoring of the flow rate in the connecting pipe. Under the action of the second pipeline pump, the extinguishing agent in the storage tank, through the combined action of the second pipeline valve assembly and the second management regulating valve, achieves a fire extinguishing mode where different types of extinguishing agents are mixed and / or work together. A second pipeline regulating valve, with an adjustable flow surface connected to the connecting pipe of the second pipeline, allows for flexible and precise automatic adjustment of its opening, enabling accurate control of parameters such as flow rate, pressure, and level of the extinguishing agent entering the first pipeline from the storage tank, ensuring a stable mixing ratio between the extinguishing agent in the storage tank and the extinguishing agent in the water tank.
