Technical Field

[0006]

[0001] The present invention relates to the field of fire extinguishing technology for fire fighting, and more particularly, to a foam fire extinguishing device.

Background Art

[0002] The foam fire extinguishing device is obtained by preparing hydrocarbon compounds, etc., and forms a dense foam layer on the fuel surface to block oxygen, enabling it to spread rapidly and extinguish the fire quickly. The current foam fire extinguishing device has a water pump to apply high pressure to the water supply and drainage, pressurizes the water source supplied from the outside, and supplies it to the compression foaming process to obtain a better fire extinguishing effect. In actual use, by adjusting the water supply amount and pressure, releasing the foam and water supply when a fire occurs, and starting the water pump, the foam is injected into the water at a predetermined ratio to generate a mixed foam liquid, which is ejected from the discharge pipe to extinguish the fire.

[0003] However, the conventional foam fire extinguishing equipment is large in volume and not suitable for transportation and carrying. As a result, there is a problem that the application range of the fire extinguishing operation is limited. Especially in application scenarios where logistics park areas and lithium battery fires occur frequently, in the conventional foam fire extinguishing method, it is necessary to additionally arrange various pump bodies and internal components, which inhibits the compact assembly and adaptability of the entire device and greatly affects the efficiency of the fire extinguishing operation.

[Effects of the Invention]

[0016] According to the present invention, the following technical effects can be obtained by employing the above technical means.

[0017] (1) The foam fire extinguishing system of this application arranges the foam concentrate tank, peristaltic pump, water pump, and air compressor in a horizontal, opposing configuration, allowing each component module to be uniformly and centrally arranged inside the machine box.

Modes for Carrying Out the Invention

[0023] To make the objectives, technical means, and beneficial effects of the embodiments of the present invention clearer, the technical content of the present invention will be clearly and completely described below while referring to the accompanying drawings related to the embodiments of the present invention. Note that the embodiments described here are only some of the embodiments of the present invention and do not limit all the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments that can be conceived by those skilled in the art without creative labor are included in the protection scope of the present invention. Therefore, the detailed description of the embodiments of the present invention described below with reference to the accompanying drawings does not limit the technical scope according to the claims of the present invention, but merely shows the selected embodiments of the present invention.

[0024] Example Referring to FIGS. 1 to 6, the foam fire extinguishing device of this embodiment includes a machine case 1 and a water pump 2, a peristaltic pump 3, a foam concentrate tank 4, and an air compressor 5 arranged inside it. The foam concentrate tank 4 and the peristaltic pump 3 are connected to the input end of the water pump 2 via pipes, and the air compressor 5 is connected to the output end of the water pump 2 via a pipe. Further, a water supply pipeline provided in parallel with the foam concentrate tank 4 is further provided at the input end of the water pump 2, and the output end of the water pump 2 is connected to an external fire hose A. The foam concentrate tank 4 and the peristaltic pump 3 are arranged horizontally and oppositely on the same side of the water pump 2, and the air compressor 5 is arranged horizontally and oppositely on the opposite side of the water pump 2.

[0025] In the above-mentioned foam fire extinguishing device, with the water pump 2 as the center, the foam concentrate tank 4 and the peristaltic pump 3 are arranged horizontally and oppositely on one side, the water supply pipeline is arranged horizontally and oppositely on another side, and further the air compressor 5 and the output side pipeline are arranged horizontally and oppositely on another side. By doing so, each component module is regularly arranged around the water pump 2. As a result, the water supply and drainage layout of the entire device becomes clearer, and it is easier to independently remove and maintain each component module. Also, by arranging the foam concentrate tank 4, the peristaltic pump 3, the water pump 2, and the air compressor 5 horizontally and oppositely, each component module can be integrated and concentrated inside the machine case 1, reducing the volume and occupied space of the device, making the entire device more compact and lightweight, and facilitating transportation and on-site work.

[0026] Furthermore, the horizontal, opposing arrangement allows each component module to be placed within the same horizontal space, minimizing the height of the machine box 1 and resulting in a flatter overall shape. As a result, it becomes easier for users to transport and move the device at any time, and it can also be used as an installation platform on-site.

[0027] As shown in Figures 2 and 3, in this embodiment, a three-way joint 6 is provided at the input end of the water pump 2, and the peristaltic pump 3 is connected to one end of the three-way joint 6 via a drain pipe 7. Because the three-way joint 6 directly connects the supply routes from the peristaltic pump 3 and the foam concentrate tank 4 to the input end of the water pump 2, complex piping connections can be avoided, fluid transport losses can be reduced, and the mixing efficiency and accuracy of the foam concentrate and water source can be improved. In addition, the three-way joint 6 is easy to install and remove, allowing for quick assembly and maintenance of the equipment. Furthermore, since the peristaltic pump 3 and the three-way joint 6 are directly connected via the drain pipe 7, the complexity of the system is further reduced, and inspection and repair can be easily performed.

[0028] Furthermore, the foam concentrate tank 4 is positioned in parallel to the front of the peristaltic pump 3, and the foam concentrate tank 4 is connected to the peristaltic pump 3 via a suction pipe 8. This arrangement, with the foam concentrate tank 4 and the peristaltic pump 3 located on the same side, minimizes overlap in the internal structure of the device and optimizes the space utilization rate inside the machine casing 1. This compact design further reduces the overall size of the device, improving portability and transportability. In addition, the direct connection of the foam concentrate tank 4 to the peristaltic pump 3 via the suction pipe 8 shortens the liquid transport path, reduces flow resistance and losses, and allows for smoother supply of the foam concentrate, further improving mixing efficiency.

[0029] The peristaltic pump 3, water pump 2, and three-way joint 6 are arranged in parallel to each other, with the peristaltic pump 3 and the three-way joint 6 facing each other on either side of the water pump 2, and the three-way joint 6 is connected to the water supply pipeline. By symmetrically arranging the peristaltic pump 3 and the three-way joint 6 on either side of the water pump 2, the water source and foam concentrate can be assigned to different sides, clearly separating the supply routes. Furthermore, the symmetrical arrangement effectively balances the weight of the device, improving the overall stability of the device and making it easier to move and position, which is particularly advantageous on uneven ground or in confined fire scenes. In addition, because each component is arranged in parallel, the location of the main parts is clear and easily accessible, allowing for efficient inspection and maintenance work.

[0030] In one embodiment, the water supply pipeline is configured as a water storage bag (not shown) placed inside the machine box 1. The water storage bag functions as the water source for the device itself, enabling foam firefighting operations without the need for an external water source, and significantly compensating for the drawback of not being able to secure a water source at the firefighting site. Furthermore, the water storage bag can be easily replenished as needed as a water source built into the device, improving flexibility at the site of use.

[0031] In another embodiment, the water supply pipeline is configured as a water supply joint 9 that is at least partially exposed to the outside of the machine box 1 (see Figures 2 and 3). The water supply joint 9 is directly connected to an external water supply line and is used to input water for firefighting.

[0032] More preferably, the water supply pipeline is provided with a water storage bag and a water supply joint 9 connected in parallel to the water pump 2, so that either one can be selected and used as a water source depending on the situation.

[0033] As shown in Figures 2 and 3, in this embodiment, a water outlet joint 10 and an adapter pipe 11 connected to the water outlet joint 10 are provided at the output end of the water pump 2, and the adapter pipe 11 is fixed to an opening 13 formed in the machine box 1 by a fixing plate 12. The adapter pipe 11 is detachably connected to the fire hose A. This allows for quick attachment and replacement of the fire hose A during use, improving the flexibility of the device, allowing it to adapt to situations with different hose lengths and specifications, and enabling rapid deployment in various fire scenes. In addition, since the adapter pipe 11 is firmly attached to the opening 13 of the machine box 1 by the fixing plate 12, the risk of the adapter pipe 11 loosening or falling off due to pressure fluctuations or external forces is reduced, improving the safety and reliability of the device's operation.

[0034] As shown in Figures 3 and 6, the foam fire extinguishing system of this embodiment further comprises a control circuit board 14 and a battery unit 15. The control circuit board 14 is electrically connected to the battery unit 15, and the foam concentrate tank 4 is positioned directly above the battery unit 15.

[0035] Specifically, a battery storage chamber 16 is enclosed in the inner corner of the machine casing 1, the battery storage chamber 16 has an upper opening, and the battery unit 15 is housed in the battery storage chamber 16. If the battery unit 15 ignites, the outer shell of the foam concentrate tank 4 melts due to the heat, and the foam concentrate inside the tank flows into the battery storage chamber 16 through the upper opening, actively extinguishing the fire. In other words, by positioning the foam concentrate tank 4 directly above the battery unit 15, when the battery unit 15 inside the battery storage chamber 16 spontaneously ignites or overheats, the outer shell of the tank (made of resin or plastic material) melts, the foam concentrate flows out quickly and is introduced into the battery storage chamber 16, achieving rapid cooling and fire extinguishing, and exhibiting a remarkable active protection effect.

[0036] As is understood, conventional fire extinguishing systems generally use battery units as a power source. Diesel engines are difficult to maintain, prone to failure during emergency use, and bulky, making compact configurations difficult. Furthermore, at fire rescue scenes, it is necessary to completely shut off commercial power to prevent electric shock to firefighters. For this reason, in this embodiment, a battery unit 15 that can be used as a temporary power source is provided in the battery storage compartment 16 within the machine box 1 to ensure the normal operation of the entire system. In addition, from the standpoint of preventing battery ignition inside the machine box 1, by positioning the foam concentrate tank 4 directly above the battery unit 15, the outer shell of the foam concentrate tank 4 can be rapidly dissolved the moment the battery spontaneously ignites, allowing the foam concentrate to be quickly discharged and actively extinguishing the fire.

[0037] This foam fire extinguishing system is further equipped with a control panel 17. The control panel 17 is electrically connected to the control circuit board 14 and is located on the side of the machine casing 1. The control panel 17 is provided with at least a display 18, control switches 19, and a charging interface 20. The charging interface 20 is for connecting to an external power source to charge the built-in battery unit 15. Multiple control switches 19 are provided and are used to individually control the start and stop of the operation of the water pump 2, peristaltic pump 3, and air compressor 5. Furthermore, the control switches 19 are also equipped with operation keys such as a one-touch start function and an emergency stop function, enabling rapid start and stop of the entire system in various emergency situations.

[0038] As shown in Figures 2 and 4, in this embodiment, the machine box 1 comprises a housing 21 having an upper opening and a cover 22 detachably disposed on the housing 21. The cover 22 is provided with two handles 23 and an openable / closable liquid injection port 24 that exposes the foam concentrate tank 4. The two handles 23 are provided on both the left and right sides, which is convenient for the user when lifting and transporting the entire device. The liquid injection port 24 is configured to be openable and closable by a stopper cap or an openable / closable flip cover (see Figure 1), which is suitable for quickly replenishing the foam concentrate.

[0039] The above merely describes preferred embodiments of the present invention, and the scope of protection of the present invention is not limited to these embodiments. All technical configurations based on the fundamental concept of the present invention fall within the scope of protection of the present invention. [Explanation of Symbols]
