Description

Technical Field

[0001] This utility model relates to the field of fire protection equipment technology, specifically to a mobile fire extinguishing device. Background Technology

[0002] Containers play a vital role in the logistics and warehousing industries; however, frequent container fires cause severe economic and environmental losses. Therefore, container fire extinguishing technology has become an important research direction in the field of fire safety. With technological advancements, fire extinguishing techniques have continuously improved, from the application of traditional dry powder and water-based extinguishing agents to the development of intelligent fire extinguishing systems incorporating information technology, all striving to improve fire extinguishing efficiency and effectiveness.

[0003] Currently, there are various fire extinguishing devices for container fires. For example, Chinese patent document CN 118022217A discloses a container fire extinguishing system, which designs ventilated mask shells at both ends of the container, uses a fixed clamping mechanism to seal the inflatable mask shells to the ventilated mask shells, and then fills the inside of the container with inert gas through the inflation connector to reduce the oxygen concentration and thus extinguish the fire.

[0004] This existing technical solution has significant drawbacks. First, the time required for extinguishing fires using inert gas is relatively long, making it impossible to quickly put out a fire. Second, when the container door is opened for inspection, unextinguished sparks may remain deep inside, leading to secondary combustion upon contact with sufficient oxygen, severely impacting extinguishing efficiency. Furthermore, this method is relatively simplistic and poorly adaptable to different types of fires, failing to flexibly adjust extinguishing strategies based on actual conditions and thus unable to meet the demands for highly efficient fire suppression. Utility Model Content

[0005] In view of this, the present invention provides a mobile fire extinguishing device to solve the problem of limited fire extinguishing location of existing fire extinguishing devices.

[0006] This utility model provides a mobile fire extinguishing device, comprising: a walking device; a storage tank disposed on the walking device, the storage tank being adapted to contain fire extinguishing agent, the storage tank having a discharge port; a fire extinguishing pipe and a nozzle, the nozzle being connected to the discharge port of the storage tank through the fire extinguishing pipe; and an impact assembly disposed on the walking device, the impact assembly having an impact end, the nozzle being connected to the impact end of the impact assembly.

[0007] Through the above-described configuration, the walking mechanism provides mobility for the entire device, enabling it to quickly reach the fire location and allowing the extinguishing device to rapidly approach the fire source, thus improving the timeliness of fire suppression. The storage tank, mounted on the walking mechanism, can hold different types of extinguishing agents to cope with various fire situations. The outlet design ensures that the extinguishing agent flows smoothly out of the storage tank and into the extinguishing pipeline. The extinguishing pipeline connects the storage tank and the nozzle, transporting the extinguishing agent. The impact component, mounted on the walking mechanism, has its impact end connected to the nozzle. The impact drive mechanism accurately delivers the nozzle to the fire source and applies impact force, allowing the extinguishing agent to penetrate the flames and reach the base. Through the coordinated operation of the impact component and the walking mechanism, the extinguishing device can move flexibly at the fire scene, quickly approach the fire source, and achieve precise fire suppression.

[0008] Optionally, the nozzle has a conical structure.

[0009] With the above configuration, the nozzle is designed with a conical structure, which enhances the impact force on the container, allowing it to better impact the container and perform fire extinguishing operations.

[0010] Optionally, the nozzle has a plurality of nozzles evenly arranged around the conical surface of the conical structure.

[0011] With the above configuration, multiple nozzles are evenly distributed around the conical surface of the cone structure, allowing the extinguishing agent to be sprayed more evenly onto the fire source. This avoids incomplete extinguishing in some areas due to uneven distribution of the extinguishing agent, further improving extinguishing efficiency and ensuring that the flames are effectively extinguished from all directions, thus being put out more quickly.

[0012] Optionally, the impact assembly includes an impact driving mechanism, the top end of which is the impact end.

[0013] With the above configuration, the impact drive mechanism in the impact assembly, with its top end serving as the impact end, can provide a powerful driving force to the nozzle. This design allows the nozzle to be accurately delivered to the fire source with sufficient force under the action of the impact drive mechanism, ensuring that the extinguishing agent can effectively penetrate the flame and reach the base of the fire, thereby improving the effectiveness and efficiency of fire extinguishing.

[0014] Optionally, the impact drive mechanism is provided with a receiving cavity for accommodating the fire extinguishing pipe.

[0015] Through the above-described design, the containment chamber provides a stable space for the fire extinguishing pipeline. When the impact drive mechanism operates, its internal containment chamber effectively protects the fire extinguishing pipeline, preventing damage such as cracking, deformation, or displacement caused by impact, vibration, or other external forces. This ensures the stable transmission of the extinguishing agent within the pipeline, smoothly reaching the nozzle from the storage tank, guaranteeing the continuity and reliability of the fire extinguishing process, and thus improving the overall performance and effectiveness of the fire extinguishing device.

[0016] Optionally, the impact assembly further includes a lifting drive mechanism, which is mounted on the walking device, and the lifting end of the lifting drive mechanism is connected to the impact drive mechanism.

[0017] Through the above configuration, the lifting drive mechanism can adjust the height of the impact drive mechanism. Because it is mounted on the traveling device and the lifting end is connected to the impact drive mechanism, when facing fire sources of different heights, the lifting drive mechanism can change the height of the impact drive mechanism and the connected nozzle, allowing the nozzle to be better aligned with the fire source. This ensures that the extinguishing agent can be effectively sprayed onto the fire source, improving the adaptability of the fire extinguishing device to fire sources of different heights and its extinguishing effect.

[0018] Optionally, one end of the impact drive mechanism is hinged to the walking device, one end of the lifting drive mechanism is hinged to the walking device, and the lifting end of the lifting drive mechanism is hinged to the end of the impact drive mechanism away from the walking device.

[0019] Through the above configuration, the hinged connection establishes a tight yet flexible connection between both the impact drive mechanism and the lifting drive mechanism and the traveling device. The hinged connection between the lifting end of the lifting drive mechanism and the end of the impact drive mechanism furthest from the traveling device allows for smoother adjustment of the impact drive mechanism's height during operation, thus better adapting to different working environments and variations in fire source height. This connection method ensures that the nozzle can accurately aim at the fire source, improving the fire extinguishing device's adaptability to fire sources at different heights in complex environments and its fire extinguishing efficiency.

[0020] Optionally, the walking device has a reserved external interface for connecting an external fire extinguishing agent, and the fire extinguishing pipeline is connected to the discharge port of the storage tank through a three-way valve. The three-way valve has a second inlet, which is connected to the reserved external interface.

[0021] With the above setup, when the extinguishing agent in the storage tank is about to run out, an external extinguishing agent supply source can be quickly connected via the reserved external interface. This allows the external extinguishing agent to flow into the extinguishing pipeline through the second inlet of the three-way valve, ensuring uninterrupted firefighting operations. This design increases the flexibility and adaptability of the fire extinguishing device, enabling it to continuously and effectively extinguish fires of varying sizes. Simultaneously, the three-way valve facilitates the control of the extinguishing agent flow, ensuring a stable and efficient delivery of the extinguishing agent to the nozzles, thus improving firefighting efficiency.

[0022] Optionally, the storage tank has multiple storage tanks, and the outlet of each storage tank is connected to one of the fire extinguishing pipes. The multiple fire extinguishing pipes are connected to the nozzles, and a check valve is provided at the connection between the fire extinguishing pipe and the nozzle.

[0023] Through the above-described design, the multiple storage tanks increase the variety and total amount of extinguishing agents that can be stored in the fire extinguishing system. Different storage tanks can hold different types of extinguishing agents to meet the needs of various fire types. Each storage tank's outlet is connected to a separate extinguishing pipeline, ensuring independent delivery of different extinguishing agents and preventing interference between them. Multiple extinguishing pipelines are connected to nozzles, allowing for the selection of the appropriate extinguishing agent based on the actual situation during firefighting. The check valves installed at the connections between the extinguishing pipelines and nozzles prevent backflow of the extinguishing agent, ensuring unidirectional flow and guaranteeing the stability and reliability of the fire extinguishing process.

[0024] Optionally, the impact assembly is provided with a thermal imaging detection device.

[0025] With the above setup, the thermal imaging detection device can detect the location and temperature distribution of the fire source in real time. During firefighting, operators can use the accurate information provided by the thermal imaging detection device to more precisely control the movement direction of the impact components, ensuring that the nozzles are accurately aimed at the fire source, greatly improving the accuracy and efficiency of firefighting.

[0035] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0036] The following is combined Figures 1 to 6 The following describes embodiments of the present invention.

[0037] like Figure 1 As shown, this is a specific implementation of the mobile fire extinguishing device provided in this embodiment, including: a walking device, a storage tank 3, a fire extinguishing pipeline, a nozzle 5, and an impact assembly.

[0038] Specifically, the walking device includes a base plate 1 and casters 2 placed at the bottom of the base plate 1. Storage tanks 3 are mounted on the base plate 1 within the walking device. The storage tanks 3 are used to hold extinguishing agents; three storage tanks 3 respectively store dry powder, water, and extinguishing gas. Each storage tank 3 has a discharge port 4, located on its side wall. An extinguishing pipe and nozzles 5 are also included; the nozzles 5 are connected to the discharge port 4 of the storage tanks 3 via the extinguishing pipe. An impact assembly is mounted on the base plate 1 within the walking device; the impact assembly has an impact end, and the nozzles 5 are connected to the impact end of the impact assembly.

[0039] In this embodiment, the walking device provides mobility for the entire device, enabling it to quickly reach the fire location and allowing the fire extinguishing device to rapidly approach the fire source, improving the timeliness of fire suppression. The storage tank 3 is mounted on the walking device and can hold different types of extinguishing agents to cope with various fire situations. The outlet 4 ensures that the extinguishing agent can smoothly flow out of the storage tank 3 and into the extinguishing pipeline. The extinguishing pipeline connects the storage tank 3 and the nozzle 5, transporting the extinguishing agent. The impact component is mounted on the walking device, with its impact end connected to the nozzle 5. The impact drive mechanism 7 accurately delivers the nozzle 5 to the fire source and applies impact force, allowing the extinguishing agent to penetrate the flames and reach the base. Through the coordinated operation of the impact component and the walking device, the fire extinguishing device can move flexibly at the fire scene, quickly approach the fire source, and achieve precise fire suppression.

[0040] like Figure 2 As shown, this is a specific implementation of the mobile fire extinguishing device provided in this embodiment, wherein the nozzle 5 has a conical structure.

[0041] Specifically, the cone-shaped structure of nozzle 5 has significant advantages. On the one hand, it allows the impact component to penetrate the container more easily, thus enabling precise extinguishing of the fire at its source. On the other hand, it allows the extinguishing agent to be sprayed in a more concentrated manner, enhancing the impact force of the extinguishing agent and enabling it to penetrate the flames more effectively and reach the base of the fire, thereby greatly improving extinguishing efficiency.

[0042] like Figure 2 As shown, this is a specific embodiment of the mobile fire extinguishing device provided in this example. The nozzle 6 of the nozzle 5 has a plurality of nozzles evenly arranged around the conical surface of the conical structure.

[0043] Specifically, the nozzles 6 of the nozzle 5 are evenly distributed around the conical surface of the conical structure. These nozzles 6 can simultaneously spray the extinguishing agent from different angles, allowing the extinguishing agent to more comprehensively cover every corner of the container's interior. This is especially beneficial for large containers or containers with complex internal structures, effectively avoiding blind spots in fire suppression. The evenly distributed nozzles 6 ensure more uniform spraying of the extinguishing agent, preventing excessively high or low pressure in certain areas, improving the stability of the fire suppression effect, and reducing the damage to the container and its contents caused by the fire.

[0044] like Figure 1 As shown, this is a specific implementation of the mobile fire extinguishing device provided in this embodiment. The impact component includes an impact driving mechanism 7, and the top end of the impact driving mechanism 7 is the impact end.

[0045] Specifically, the impact drive mechanism 7 is a multi-segment design with interlocking sections, allowing it to extend and retract as needed during operation. When facing containers of varying heights or fire sources, the multi-segment impact drive mechanism 7 can flexibly change its length, ensuring the nozzle 5 accurately reaches the fire source. The impact drive mechanism 7 is hydraulically driven, generating significant impact force, enabling the nozzle 5 to powerfully impact the container for fire extinguishing. Initially, the impact drive mechanism 7 can retract to a shorter length for easy movement and storage of the fire extinguishing device. During fire extinguishing, it can gradually extend as needed to adapt to different working conditions.

[0046] like Figure 3 As shown, this is a specific implementation of the mobile fire extinguishing device provided in this embodiment. The impact drive mechanism 7 is provided with a receiving cavity 8 for accommodating the fire extinguishing pipeline.

[0047] Specifically, the receiving cavity 8 within the impact drive mechanism 7 provides a safe and reliable space for the fire extinguishing pipeline. During firefighting operations, the fire extinguishing pipeline needs to move along with the impact drive mechanism 7 to ensure that the extinguishing agent is accurately delivered to the nozzle 5. The design of the receiving cavity 8 allows the fire extinguishing pipeline to be stably positioned inside the impact drive mechanism 7, avoiding external interference and damage during movement. It also provides a certain degree of protection for the fire extinguishing pipeline, preventing it from being affected by the high temperature, flames, or other hazardous factors at the fire scene.

[0048] like Figure 4 As shown, this is a specific implementation of the mobile fire extinguishing device provided in this embodiment. The impact component further includes a lifting drive mechanism, which is disposed on the walking device, and the lifting end of the lifting drive mechanism is connected to the impact drive mechanism 7.

[0049] Specifically, the lifting drive mechanism consists of a guide column 9 and a push rod 10. The guide column 9 provides a guide for the push rod 10 to extend or retract, and the push rod 10 is connected to the impact drive mechanism 7. During fire extinguishing, when it is necessary to adjust the height of the nozzle 5 to better align with the fire source, the push rod 10, guided by the guide column 9, can smoothly push or pull the impact drive mechanism 7 to rise or fall.

[0050] like Figure 1 , Figure 4 As shown, this is a specific implementation of the mobile fire extinguishing device provided in this embodiment. One end of the impact drive mechanism 7 is hinged to the walking device, one end of the lifting drive mechanism is hinged to the walking device, and the lifting end of the lifting drive mechanism is hinged to the end of the impact drive mechanism 7 away from the walking device.

[0051] Specifically, the outermost layer of the impact drive mechanism 7 is hinged to the base plate 1 in the traveling device, the guide column 9 in the lifting drive mechanism is hinged to the base plate 1, and the connection between the push rod 10 and the impact drive mechanism 7 is also hinged. In complex firefighting scenarios, such as containers of different heights, uneven ground, or tilted containers, the height of the impact drive mechanism 7 can be adjusted via the lifting drive mechanism. Simultaneously, the impact drive mechanism 7 can adjust its angle using its hinge point with the traveling device, ensuring that the nozzle 5 can accurately target the fire source, greatly improving the targeting and effectiveness of firefighting.

[0052] In other embodiments, the cooperation between the impact drive mechanism 7 and the lifting mechanism can also be achieved through a slide rail slider structure. A slider is installed in the lifting section of the lifting mechanism, and a corresponding slide rail is installed at the bottom of the impact drive mechanism 7. When the lifting mechanism rises, the slider moves obliquely upward within the slide rail, lifting the impact drive mechanism 7; when it descends, the slider moves downward, causing the impact drive mechanism 7 to descend. The slide rail slider structure provides more stable and precise motion guidance. The movement of the slider on the slide rail ensures that the impact drive mechanism 7 always moves in a predetermined direction during the lifting process, avoiding deviation or swaying, thereby improving the accuracy of the nozzle 5 in aligning with the fire source.

[0053] like Figure 1 , Figure 5 As shown, this is a specific implementation of the mobile fire extinguishing device provided in this embodiment. The walking device has a reserved external interface 11 for connecting an external fire extinguishing agent. The fire extinguishing pipeline is connected to the discharge port 4 of the storage tank 3 through a three-way valve 12. The three-way valve 12 has a second inlet, which is connected to the reserved external interface 11.

[0054] Specifically, the external interface is equipped with three interfaces corresponding to the three types of extinguishing agents stored in the storage tank 3. When a certain type of extinguishing agent in the storage tank 3 is about to run out, it can be quickly connected to an external supply source of the same type of extinguishing agent through the corresponding external interface, ensuring the continuity of fire extinguishing operations. The fire extinguishing pipeline is connected to the outlet 4 of the storage tank 3 through a three-way valve 12, and the second inlet of the three-way valve 12 is connected to the reserved external interface 11, allowing external extinguishing agents to smoothly enter the fire extinguishing pipeline. This improves the continuous fire extinguishing capability of the fire extinguishing device, ensuring that operation will not be interrupted due to the depletion of extinguishing agents during long-term fire extinguishing operations.

[0055] In other embodiments, a multi-way solenoid valve can be used instead of the three-way valve 12 to connect and switch between the discharge port 4 of the storage tank 3, different external extinguishing agent interfaces, and extinguishing pipelines. The multi-way solenoid valve can achieve rapid and accurate channel switching through electronic control, with a fast response speed. Furthermore, it can be programmed to control different extinguishing needs, improving the automation and flexibility of the extinguishing system.

[0056] like Figure 5 , Figure 6 As shown, this is a specific implementation of the mobile fire extinguishing device provided in this embodiment. The storage tank 3 has multiple storage tanks, and the outlet 4 of each storage tank 3 is connected to a fire extinguishing pipe. The multiple fire extinguishing pipes are connected to the nozzles 5 respectively, and a check valve 16 is provided at the connection between the fire extinguishing pipe and the nozzle 5.

[0057] Specifically, there are multiple storage tanks 3, each equipped with a pump to provide the power for the extinguishing agent to enter the extinguishing pipeline and be sprayed. The inlets 13 of the dry powder tank and water tank are located on the top surface of the storage tank 3, and also have inlets 14 for regular cleaning. The inlet 13 of the air tank is smaller and located on the side wall of the storage tank 3. The inlets 13 allow for convenient replenishment of extinguishing agent when the remaining amount in the storage tank 3 is low. The outlet 4 of each storage tank 3 is connected to a separate extinguishing pipeline, ensuring independent delivery of various extinguishing agents and avoiding interference between different extinguishing agents. Multiple extinguishing pipelines are connected to nozzles 5, allowing for the selection of the appropriate extinguishing agent during the firefighting process, improving the effectiveness and targeting of the extinguishing efforts. During the fire extinguishing process, the extinguishing agent may flow back into the storage tank 3 or other pipelines, affecting the effectiveness of the next fire extinguishing. The check valve 16 can prevent the extinguishing agent from flowing back, ensuring that the extinguishing agent can only flow from the fire extinguishing pipeline to the nozzle 5, thus ensuring the purity of the extinguishing agent and improving the reliability of the fire extinguishing system.

[0058] like Figure 1 As shown, this is a specific implementation of the mobile fire extinguishing device provided in this embodiment, wherein a thermal imaging detection device 15 is provided on the impact component.

[0059] Specifically, a thermal imaging detection device 15 is installed on the impact assembly, which can flexibly detect different areas as the impact assembly moves, quickly and accurately determining the location of the fire source. At the same time, the thermal imaging detection device 15 can also detect the fire extinguishing effect. When the temperature drops to a certain level, it indicates that the fire extinguishing work has been effective, and the operator can use this information to determine whether to continue the fire extinguishing operation or adjust the fire extinguishing strategy.

[0060] Working principle:

[0061] When firefighting is required, the walking device moves the fire extinguishing equipment to the vicinity of the fire scene. The thermal imaging detection device 15 can detect the temperature distribution at the fire scene and quickly and accurately determine the location of the fire source. Based on the detection results, the height of the impact drive mechanism 7 is adjusted by the lifting drive mechanism, and the angle of the impact drive mechanism 7 is adjusted according to the actual situation, so that the nozzle 5 is accurately aimed at the fire source. The pump in the storage tank 3 provides power to spray the extinguishing agent to the fire source. If the extinguishing agent in the storage tank 3 is insufficient, the reserved external interface 11 can be connected to external extinguishing agent. The extinguishing pipeline is connected to the outlet 4 of the storage tank 3 through the three-way valve 12, and the second inlet of the three-way valve 12 is connected to the reserved external interface 11, so that the extinguishing agent in the storage tank 3 or the externally connected extinguishing agent can be selected as needed. Multiple storage tanks 3 can store different types of extinguishing agents. The outlet 4 of each storage tank 3 is connected to a fire extinguishing pipeline, and multiple fire extinguishing pipelines are connected to the nozzles 5. A check valve 16 is provided at the connection between the fire extinguishing pipeline and the nozzle 5 to prevent the extinguishing agent from flowing back. Through the coordinated action of these components, the fire can be effectively extinguished.

[0062] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and all such modifications and variations fall within the scope of the present invention.
