Detailed Implementation

[0029] 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, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to represent selected embodiments of this utility model.

[0030] Example

[0031] Combination Figures 1 to 6 This embodiment provides a foam fire extinguishing device, including a housing 1, and a water pump 2, a peristaltic pump 3, a foam concentrate tank 4, and an air compressor 5 disposed within the housing 1. The foam concentrate tank 4 and the peristaltic pump 3 are connected to the input end of the water pump 2 via pipelines, and the air compressor 5 is connected to the output end of the water pump 2 via pipelines. The input end of the water pump 2 is also provided with a water supply pipeline connected in parallel with the foam concentrate tank 4, and the output end of the water pump 2 is used to connect to an external fire-fighting pipe A. The foam concentrate tank 4 and the peristaltic pump 3 are horizontally connected to each other on the same side of the water pump 2, and the air compressor 5 is horizontally connected to each other on the other side of the water pump 2.

[0032] The foam fire extinguishing equipment described above, centered on water pump 2, has foam concentrate tank 4 and peristaltic pump 3 horizontally connected to one side, water supply pipeline horizontally connected to the other side, and air compressor 5 and output pipeline horizontally connected to the other side. This arrangement of structural modules around water pump 2 makes the overall water inlet and outlet layout clearer and facilitates independent disassembly, assembly, maintenance, and use of each module. Furthermore, by using a horizontally connected arrangement for foam concentrate tank 4, peristaltic pump 3, water pump 2, and air compressor 5, all structural modules are unified and concentrated inside the casing 1, reducing the equipment's size and space occupation, making the entire machine more compact, lightweight, and convenient for transportation and on-site use.

[0033] In addition, by using a horizontal docking method to arrange each structural module in the same horizontal space, the height of the chassis 1 can be minimized, making the whole machine more flat in shape. This not only makes it easy for users to move and relocate at any time, but it can also be used as a placement platform on site.

[0034] like Figure 2 and Figure 3As shown, in this embodiment, the input end of the water pump 2 is equipped with a three-way pipe 6, and the peristaltic pump 3 is connected to one end of the three-way pipe 6 through a liquid outlet pipe 7. The three-way pipe 6 allows the liquid supply path of the peristaltic pump 3 and the foam concentrate tank 4 to directly connect with the input end of the water pump 2, avoiding complex piping connections, reducing fluid transmission losses, and thus improving the mixing efficiency and accuracy of the foam concentrate and water source. Furthermore, the three-way pipe 6 is easier to disassemble and assemble, making equipment installation and maintenance more convenient and faster. The direct connection between the peristaltic pump 3 and the three-way pipe 6 through the liquid outlet pipe 7 further reduces system complexity and facilitates inspection and maintenance.

[0035] Furthermore, the foam concentrate tank 4 is arranged side-by-side in front of the peristaltic pump 3, and the foam concentrate tank 4 is connected to the peristaltic pump 3 via an inlet pipe 8. Thus, the foam concentrate tank 4 and the peristaltic pump 3, located on the same side, are arranged side-by-side, reducing the stacking of internal structures and optimizing the space utilization within the chassis 1. This compact design makes the overall equipment smaller, easier to carry and transport. Moreover, the direct connection of the foam concentrate tank 4 to the peristaltic pump 3 via the inlet pipe 8 shortens the liquid transmission path, reduces flow resistance and losses, ensuring a smoother supply of foam concentrate and further improving mixing efficiency.

[0036] The peristaltic pump 3, water pump 2, and T-connector 6 are arranged side-by-side, with the peristaltic pump 3 and T-connector 6 positioned opposite each other on either side of the water pump 2. The T-connector 6 is connected to the water supply pipeline. The symmetrical arrangement of the peristaltic pump 3 and T-connector 6 on both sides of the water pump 2 ensures that the water source and foam concentrate are allocated to different sides, clearly defining the different water and concentrate supplies. This symmetrical arrangement effectively balances the weight distribution of the equipment, making the overall equipment more stable and easier to move and deploy, especially suitable for uneven or confined fire scenes. The side-by-side arrangement of all structures also makes the location of all core components clear and easily accessible.

[0037] In one embodiment, the water supply pipeline is configured as a water storage bag (not shown) placed inside the chassis 1. The water storage bag serves directly as the water source for the entire machine, enabling foam fire extinguishing without the need for an external water source, greatly compensating for the lack of water supply at the fire scene. Moreover, the water storage bag, being a self-contained water source, is convenient to replenish at any time.

[0038] In another embodiment, the water supply line is configured such that the inlet connector 9 is at least partially exposed outside the chassis 1 (e.g., Figure 2 and Figure 3 (As shown). Obviously, the water inlet connector 9 is used to directly connect to an external water line to supply water for firefighting.

[0039] Preferably, the water supply pipeline is equipped with a water storage bag and a water inlet connector 9 that are connected in parallel to the water pump 2, so as to select one for water supply.

[0040] like Figure 2 and Figure 3 As shown, in this embodiment, the output end of the water pump 2 is provided with a water outlet connector 10 and an adapter pipe 11 connected to the water outlet connector 10. The adapter pipe 11 is fastened to the window 13 of the chassis 1 by a fixing plate 12. The adapter pipe 11 is detachably connected to the fire pipe A. On one hand, the detachable connection between the adapter pipe 11 and the fire pipe A allows for quick installation or replacement of the fire pipe A during use, improving the flexibility of the equipment and adapting to the needs of fire pipes of different lengths or specifications, facilitating rapid deployment in various fire scenarios. On the other hand, the adapter pipe 11 is fastened to the window 13 of the chassis 1 by the fixing plate 12, ensuring the stability of the pipe connection and avoiding the risk of the adapter pipe 11 loosening or falling off due to pressure fluctuations or external forces, thus improving the safety and reliability of the equipment operation.

[0041] like Figure 3 and Figure 6 As shown, in this embodiment, the foam fire extinguishing device also includes a control circuit board 14 and a battery assembly 15. The control circuit board 14 is electrically connected to the battery assembly 15, and the foam concentrate tank 4 is directly mounted on the battery assembly 15.

[0042] Specifically, a battery compartment 16 is enclosed at the inner corner of the chassis 1, with an exposed upper opening. The battery assembly 15 is fitted and housed within the battery compartment 16. When the battery assembly 15 spontaneously combusts, the outer shell of the foam concentrate tank 4 melts upon heating, causing the foam concentrate inside to flow into the battery compartment 16 through the upper opening for active fire suppression. Thus, by directly mounting the foam concentrate tank 4 above the battery assembly 15, the battery assembly 15 within the battery compartment 16, upon spontaneous combustion or overheating, melts the outer shell (resin or plastic material) of the foam concentrate tank 4, causing the foam concentrate to flow out and enter the battery compartment 16 through the upper opening for rapid cooling and fire suppression, achieving a significant active protection purpose.

[0043] Understandably, current fire extinguishing equipment typically uses battery packs as its power source. Diesel engines are difficult to maintain, frequently malfunction when urgently needed, and their large size makes compact installation impractical. Furthermore, in fire rescue operations, mains power must be shut off to prevent firefighters from being electrocuted. Therefore, to address temporary power supply issues, this embodiment includes an additional battery pack 15 within the battery compartment 16 of the chassis 1 for temporary power supply, ensuring normal operation of the entire unit. Moreover, to prevent spontaneous combustion of the batteries within the chassis 1, the foam concentrate tank 4 is placed directly on the battery pack 15. This allows for rapid dissolution of the outer shell of the foam concentrate tank 4 in the event of spontaneous combustion, enabling the foam concentrate to flow out and achieve active fire extinguishing.

[0044] The foam fire extinguishing equipment also includes a control panel 17. The control panel 17 is electrically connected to the control circuit board 14 and is located on one side of the chassis 1. The control panel 17 includes at least a display 18, control switches 19, and a charging interface 20. The charging interface 20 is used to connect an external power source to charge the internal battery assembly 15. Multiple control switches 19 are provided to control the operation and shutdown of the water pump 2, peristaltic pump 3, and air compressor 5. Specifically, the control switches 19 also include one-button start and emergency stop buttons to enable start-up and shutdown of the entire unit in various emergencies.

[0045] like Figure 2 and Figure 4 As shown, in this embodiment, the chassis 1 includes a housing 21 with a top opening and a cover 22 detachably mounted on the housing 21. The cover 22 has two handles 23 and an openable filling port 24 exposing the foam concentrate container 4. The two handles 23 are respectively located on the left and right sides, facilitating user lifting and carrying of the entire machine. The filling port 24 can be accessed via a plug or a flip-top cover (e.g.,...). Figure 1 (As shown) Enable activation to facilitate the rapid addition of foam concentrate.

[0046] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions that fall within the scope of this utility model's concept are protected by this utility model.
