Description

Technical Field

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

[0002] In actual fire rescue scenarios, fire scenes are often extremely complex and rapidly changing. Raging flames spread uncontrollably, accompanied by billowing smoke; the surrounding environment is highly unpredictable; building structures may become fragile due to the high temperatures, posing a constant risk of collapse; and debris is scattered everywhere, severely hindering firefighters' operations. Meanwhile, the length of fire hoses is also constrained by numerous factors. The diversity of fire locations, such as inside high-rise buildings, deep in narrow alleys, or in large industrial areas, necessitates the winding and circuitous layout of fire hoses according to the actual terrain. Sometimes, to reach the center of the fire, the hoses must extend a considerable distance. These excessively long fire hoses experience significant pressure loss during water delivery, making it difficult to maintain stable water pressure from the hoses. Therefore, adjusting the water pressure from the fire truck becomes extremely challenging.

[0003] The current standard practice is that firefighters operating water hoses wear walkie-talkies, and a dedicated person, also equipped with a walkie-talkie, is stationed at the fire pump (or fire truck). However, during firefighting operations, the personnel at the fire pump (or fire truck) struggle to quickly and accurately adjust the water pressure to effectively suppress the fire while ensuring the firefighters' safe operation, taking into account the complex fire situation, terrain, and the length and bends of the fire hoses. Therefore, when the water pressure is unsuitable during firefighting, the firefighters at the water hoses use walkie-talkies to notify the personnel at the fire pump (or fire truck) for adjustment. This method is not only inefficient and hinders rapid firefighting, but also wastes personnel by requiring dedicated staff at the fire pump (or fire truck). This issue urgently needs to be addressed. Summary of the Invention

[0004] The first aspect of this utility model is to solve the above-mentioned technical problems by providing a fire protection system that can significantly improve rescue efficiency and reduce personnel configuration, thereby effectively improving the efficiency and effectiveness of fire rescue.

[0005] A fire-fighting system includes a water nozzle and a supply module. The supply module includes a delivery pump, and the water nozzle includes a nozzle body connected to the delivery pump via a pipeline. The delivery pump has an adjustable outlet pressure. The water nozzle also includes a pressure regulating section disposed on the nozzle body, which is communicatively connected to the delivery pump and used to regulate the outlet pressure of the delivery pump. In this solution, by configuring a pressure regulating section on the water nozzle and communicating it with the delivery pump at the rear end of the pipeline, firefighters at the water nozzle can directly adjust the outlet pressure of the delivery pump via the pressure regulating section. This not only simplifies and facilitates the adjustment process, significantly improving adjustment efficiency and thus enhancing rescue efficiency and effectiveness, but also eliminates the need for dedicated personnel to adjust the delivery pump (or fire truck), reducing personnel requirements during fire rescue operations and making the fire-fighting system more optimized and better meeting market demands.

[0006] Furthermore, the water gun also includes a first communication module, and the pressure regulating unit is connected to the first communication module; the supply module also includes a second communication module, and the delivery pump is connected to the second communication module. The first communication module and the second communication module are communicatively connected. This allows the signal generated by the pressure regulating unit to communicate with the downstream supply module via the first communication module, so as to adjust the outlet water pressure of the delivery pump.

[0007] Preferably, the first communication module and the second communication module include an RS-485 module, a CAN bus module, an Ethernet module, a 4G communication module, a 5G communication module, a Zigbee module, a Wi-Fi module, an NB-IoT module, or a LoRa module.

[0008] Furthermore, it also includes a control module that plays a control role, and the control module is communicatively connected to the first communication module and the second communication module respectively. The control module is at least used to process the input signals of the pressure regulating unit and output control signals according to preset logic, thereby regulating the outlet water pressure of the delivery pump through the control signals.

[0009] Preferably, the control module includes a first controller located on the water gun body and a second controller located on the supply module. The pressure regulating unit is connected to the first controller, which is connected to a first communication module; the delivery pump is connected to the second controller, which is connected to a second communication module. The first controller is responsible for processing the input signals from the pressure regulating unit and coordinating communication with the supply module; the second controller is responsible for controlling the delivery pump and cooperating with other local devices. This distributed control method can improve the reliability and flexibility of the system, and when one controller fails, the other controller can assume partial or complete backup functions, while also facilitating functional expansion and upgrades.

[0010] Furthermore, the water gun also includes a power supply module installed on the water gun body. The power supply module includes a battery, which is connected to the pressure regulating unit and the first communication module to provide electrical energy. The power supply module is mainly used to supply power to various electrical components on the water gun body, allowing each component to draw power locally without the need to lay additional power lines, which is more conducive to rapid deployment of rescue work and improves rescue efficiency.

[0011] Furthermore, it also includes a fire truck, and the supply module is installed in the fire truck.

[0012] Preferably, the pipeline includes at least one hose module, the hose module including a hose and a first hose connector connected to both ends of the hose and a second hose connector adapted to the first hose connector, and two adjacent hoses are connected through the cooperation of the first hose connector and the second hose connector; the water gun also includes a water gun connector disposed on the water gun body and adapted to the first hose connector, and the water gun is connected to the adjacent hose through the cooperation of the water gun connector and the first hose connector; the supply module also includes a pump end connector adapted to the second hose connector, the pump end connector is connected to a delivery pump, and the delivery pump is connected to the adjacent hose through the cooperation of the pump end connector and the second hose connector.

[0013] Furthermore, it also includes a water distributor, which includes an input connector and at least two output connectors. The input connector is connected to each of the output connectors respectively. The input connector is adapted to a first water hose connector, and the output connector is adapted to a second water hose connector. The water distributor is connected between two adjacent water hoses.

[0014] Preferably, the pressure regulating unit includes an adjustment button, knob, or touchscreen.

[0015] The second aspect of this invention addresses the problem of accidents such as pipe bursting and joint detachment caused by excessive pressure adjustment. Furthermore, the supply module includes a pump pressure detection module connected to the control module. This module detects the outlet pressure of the delivery pump and feeds it back to the control module. The water gun also includes a warning module installed on the gun body, which is communicatively connected to the control module. The control module controls the warning module. By configuring the pump pressure detection module, the actual outlet pressure of the delivery pump can be detected. The warning module provides a reminder and alert to firefighters at the water gun, indicating that the actual outlet pressure of the delivery pump has reached a safe threshold. This effectively prevents firefighters from blindly adjusting the pump's outlet pressure, which could lead to excessive pressure and accidents such as pipe bursting and joint detachment, severely impacting fire rescue efforts. This invention is particularly suitable for situations with complex fire scenes and long pipelines resulting in significant pressure drops.

[0016] Preferably, the alert module includes an alert light, a speaker, or a vibrator, so that it can be detected by firefighters at the water hose location more promptly.

[0017] To address the issue of firefighters struggling to quickly assess whether the water pressure can be increased to suppress a fire based on experience, the water gun further includes a nozzle pressure detection module integrated into the nozzle body. This module is connected to the control module and detects the actual output pressure of the water gun, providing feedback to the control module. The water gun also includes a display unit integrated into the nozzle body, which is communicatively connected to the control module and displays the actual output pressure of the water gun. This not only allows firefighters to easily and efficiently see the actual output pressure of the water gun, but also facilitates convenient and efficient assessment of any pressure anomalies in the entire pipeline, thereby identifying potential pipeline malfunctions.

[0018] Compared with existing technologies, the fire protection system provided by this utility model can not only significantly improve rescue efficiency, but also reduce personnel configuration, which is conducive to improving the efficiency and effectiveness of fire rescue.

Detailed Implementation Example 1

[0030] This embodiment provides a fire-fighting system, including a water gun, piping, and a supply module. The supply module includes a delivery pump 3, and the water gun includes a water gun body 1. The water gun body 1 is connected to the delivery pump 3 via piping. Figure 1 and Figure 3 As shown, in this embodiment, the delivery pump 3 is mainly used to provide delivery power for the extinguishing agent (including water or foam mixture or other extinguishing agents), and the pipeline is mainly used to deliver the extinguishing agent delivered by the delivery pump 3 to the water gun body 1. The water gun body 1 can be an existing fire hose. The water gun body 1 is mainly used to output the extinguishing agent so that the extinguishing agent can be used to extinguish the fire.

[0031] During implementation, existing fire protection piping can be used. For example, Figure 3 or Figure 6As shown, the pipeline includes at least one hose module 2. The hose module 2 includes a hose 21 and a first hose connector 22 connected to both ends of the hose 21, and a second hose connector 23 adapted to the first hose connector 22, allowing adjacent hoses 21 to be connected via the engagement (e.g., fastening) of the first hose connector 22 and the second hose connector 23. Simultaneously, the water gun also includes a water gun connector 11 installed on the water gun body 1 and adapted to the first hose connector 22, allowing the water gun to be connected to an adjacent hose 21 via the engagement (e.g., fastening) of the water gun connector 11 and the first hose connector 22. The supply module also includes a pump end connector 31 adapted to the second hose connector 23, connected to the output end of a delivery pump 3, allowing the delivery pump 3 to be connected to an adjacent hose 21 via the engagement (e.g., fastening) of the pump end connector 31 and the second hose connector 23. In implementation, a fire truck 4 is also included, with the supply module installed on the fire truck 4. Figure 1 or Figure 3 or Figure 6 As shown, the fire truck 4 is equipped with a storage space for containing extinguishing agent. The delivery pump 3 is installed on the fire truck 4. The inlet of the delivery pump 3 is connected to the storage space, and the outlet of the delivery pump 3 is connected to the pump end connector 31. The pump end connector 31 can be fixedly installed on the fire truck 4, for example, it can be installed on the side of the fire truck 4, which makes it easier to connect during fire rescue.

[0032] It is understandable that, in practice, the structure of the water gun connector 11 can be the same as that of the second water hose connector 23, and the structure of the pump end connector 31 can be the same as that of the first water hose connector 22. The first water hose connector 22 and the second water hose connector 23 can preferentially use existing fire hose connectors, which will not be explained in detail here.

[0033] Since each hose has a predetermined length, the number of hose modules 2 configured in the pipeline during fire rescue can be determined according to the actual needs of the site. For example, one, two, three, four, or five hose modules 2 can be configured. When multiple hose modules 2 are configured, they are connected in series. In some cases, the pipeline also includes a distributor 24, which includes an inlet connector 25 and at least two outlet connectors 26. The inlet connector 25 is connected to each outlet connector 26. The inlet connector 25 is configured to fit the first hose connector 22, and the outlet connectors 26 are configured to fit the second hose connector 23. During assembly, the distributor 24 can be connected between two adjacent hoses, such as... Figure 3 or Figure 6 As shown, this is to serve the purposes of diverting water supply, controlling water flow, and improving fire extinguishing efficiency during fire rescue. In implementation, the water distributor 24 can be an existing two-way, three-way, or four-way water distributor 24, etc.

[0034] In this embodiment, the outlet pressure of the transfer pump 3 is adjustable to meet the actual needs of the site. In practice, the outlet pressure of the transfer pump 3 can be adjusted by changing the speed of the motor in the transfer pump 3. A higher motor speed results in a higher outlet pressure, and a lower motor speed results in a lower outlet pressure. Specifically, the transfer pump 3 is equipped with a frequency converter connected to the motor. The frequency converter changes the power supply frequency of the motor, thereby adjusting the motor speed and ultimately regulating the outlet pressure of the transfer pump 3.

[0035] In this embodiment, the water gun also includes a pressure regulating part 13 disposed on the water gun body 1, such as Figure 1 and Figure 2 As shown, the pressure regulating unit 13 is communicatively connected to the delivery pump 3, allowing firefighters at the water gun to directly adjust the outlet water pressure of the delivery pump 3 via the pressure regulating unit 13. In implementation, the pressure regulating unit 13 may include adjustment buttons, knobs, or a touchscreen, for example, the pressure regulating unit 13 may include two adjustment buttons, such as... Figure 2 As shown, two adjustment buttons are respectively located on the outside of the water gun body 1. Both buttons are communicatively connected to the delivery pump 3. In use, pressing one adjustment button increases the outlet water pressure of the delivery pump 3; pressing the other adjustment button decreases the outlet water pressure. Alternatively, the pressure adjustment unit 13 may include a knob located on the outside of the water gun body 1. This knob is communicatively connected to the delivery pump 3. In use, rotating the knob forward increases the outlet water pressure of the delivery pump 3, while rotating it backward decreases the outlet water pressure. Alternatively, the pressure adjustment unit 13 may include a touchscreen located on the outside of the water gun body 1. This touchscreen is communicatively connected to the delivery pump 3, allowing adjustment of the outlet water pressure via the touchscreen.

[0036] To facilitate communication between the pressure regulating unit 13 and the delivery pump 3, in implementation, such as Figure 1 and Figure 3 As shown, the water gun also includes a first communication module 14 disposed on the water gun body 1, and the pressure regulating unit 13 is connected to the first communication module 14; correspondingly, the supply module also includes a second communication module 32, and the delivery pump 3 is connected to the second communication module 32. The second communication module 32 can be disposed on the delivery pump 3 or fire truck 4, etc. The first communication module 14 and the second communication module 32 are communicatively connected, so that the signal generated by the pressure regulating unit 13 can be transmitted to the supply module at the back end through the first communication module 14, so as to control and regulate the water pressure of the delivery pump 3.

[0037] In implementation, the first communication module 14 and the second communication module 32 are adapted to each other and have various cooperative implementation methods. As an example, the first communication module 14 and the second communication module 32 can use mutually compatible wireless communication modules. For example, the first communication module 14 and the second communication module 32 can preferentially use Zigbee modules, Wi-Fi modules, NB-IoT modules, or LoRa modules, etc. Of course, 4G communication modules or 5G communication modules can also be used. As another example, the first communication module 14 and the second communication module 32 can use mutually compatible... For example, the first communication module 14 and the second communication module 32 can be wired communication modules such as RS-485 modules, CAN bus modules, or Ethernet modules. In this case, a communication line 51 needs to be configured between the water gun and the supply module. For example, in one embodiment, when laying the fire-fighting pipeline, the communication line 51 is laid simultaneously along the fire-fighting pipeline. One end of the communication line 51 is connected to the first communication module 14, and the other end of the communication line 51 is connected to the second communication module 32 to facilitate communication. In another embodiment, the communication line 51 can be integrated into the water hose 21. Figure 6 As shown, for example, when both the first communication module 14 and the second communication module 32 use RS-485 modules, the supply module is equipped with a communication connector 52, which is connected to the second communication module 32. Correspondingly, a communication line 51 is installed inside the hose 21 (e.g., inside the side wall of the hose). The communication line 51 is arranged along the length of the hose, with both ends extending out of the hose 21 and connected to communication connectors 52. Correspondingly, the water gun is also equipped with a communication connector 52, which is connected to the first communication module 14. When arranging the pipeline, the communication connector 52 at one end of the hose 21 in the hose module 2 is connected to the communication connector 52 in the supply module. The communication connectors 52 in adjacent hose modules 2 are connected to each other. The communication connector 52 of the water gun is connected to the communication connector 52 in the adjacent hose module 2, thereby realizing the communication connection between the first communication module 14 and the second communication module 32. Figure 6 As shown, the communication connection between the first communication module 14 and the second communication module 32 is achieved using a communication line 51, which is beneficial for more stable communication and less susceptible to environmental interference. It can be understood that, in implementation, when the pipeline is equipped with a water distributor 24, the water distributor 24 can also be equipped with a communication line 51 (e.g., it can be installed on the outer surface of the water distributor 24). Both ends of the communication line 51 are connected to communication connectors 52. When laying the fire-fighting pipeline, the two communication connectors 52 on the water distributor 24 can be connected to the communication connectors 52 in the adjacent fire hose module 2.

[0038] In this embodiment, the fire protection system also includes a control module that plays a control role. The control module is communicatively connected to the first communication module 14 and the second communication module 32. The control module can process the input signals of the pressure regulating unit 13 and output control signals according to preset logic to regulate the outlet water pressure of the delivery pump 3. In implementation, the control module can have various implementation methods. For example, in some cases, the control module may include a cloud server, such as... Figure 4 As shown, at this time, the first communication module 14 and the second communication module 32 can be 4G or 5G communication modules, etc., to communicate with the cloud server. For example, in some cases, the control module may include a first controller 15 disposed on the water gun body 1, with the pressure regulating unit 13 connected to the first controller 15, and the first controller 15 connected to the first communication module 14, so as to control the delivery pump 3 through the first controller 15. For example, in some cases, the control module may include a second controller 33 disposed on the supply module, with the delivery pump 3 connected to the second controller 33, and the second controller 33 connected to the second communication module 32, so as to control the delivery pump 3 through the second controller 33. In the preferred embodiment provided in this example, the control module includes a first controller 15 disposed on the water gun body 1 and a second controller 33 disposed on the supply module, such as... Figure 5 As shown, the pressure regulating unit 13 is connected to the first controller 15, and the first controller 15 is connected to the first communication module 14. The first controller 15 is responsible for processing the input signals of the pressure regulating unit 13 and coordinating communication with the supply module. The delivery pump 3 is connected to the second controller 33. For example, the second controller 33 can be preferentially connected to the frequency converter. The second controller 33 is also connected to the second communication module 32. Figure 5 As shown, the second controller 33 can be responsible for controlling the delivery pump 3 and cooperating with other local devices. This distributed control method can improve the reliability and flexibility of the system. Moreover, when one controller fails, the other controller can assume some or all of the backup functions, and it is also convenient for functional expansion and upgrades. It is understood that in implementation, both the first controller 15 and the second controller 33 can use existing controllers, such as control circuits, microcontrollers, PLCs, microprocessors, etc.

[0039] In a more refined embodiment, the water gun also includes a power supply module disposed on the water gun body 1. The power supply module includes a battery capable of storing electrical energy. The battery is connected to the pressure regulating unit 13, the first communication module 14, and / or the first controller 15. It is mainly used to supply power to the various electrical components in the water gun, allowing each electrical component to draw power locally without the need to lay additional power lines, which is more conducive to rapid deployment of rescue work and improves rescue efficiency. In implementation, lithium batteries can be preferred.

[0040] In implementation, an assembly box can be installed on the outside of the water gun body 1. The first communication module 14, the first controller 15, and the battery can all be installed in the assembly box for easy installation and removal. Of course, in other embodiments, the first communication module 14, the first controller 15, and the battery can be embedded inside the water gun body 1.

[0041] In practice, the front end of the water gun body 1 is the water outlet 10, and the rear end is equipped with a water gun connector 11, such as... Figures 1-3 As shown, this is for connecting the water hose; since the water gun body 1 can be an existing fire hose, and existing fire hoses come in various types and structures, such as some fire hoses equipped with a handle 12, such as... Figure 2 As shown; some fire hoses do not have handles 12. In implementation, for fire hose bodies 1 equipped with handles 12, the pressure regulating part 13 can be preferentially located at the handle 12, such as... Figure 1 and Figure 2 As shown, it is designed for easy operation by firefighters; of course, it can also be installed in other locations on the water gun body 1, which will not be listed here. For water gun bodies 1 without handles 12, the pressure regulating part 13 can preferably be installed on the side of the water gun body 1 for easy operation by firefighters. Example 2

[0042] Because the pipelines from the water gun to the fire truck 4 (or supply module) are usually long and complex at fire rescue sites, the change in output pressure at the water gun usually lags after directly adjusting the outlet pressure of the delivery pump 3. If the firefighter at the water gun blindly adjusts the pressure regulating part 13, on the one hand, the outlet pressure of the delivery pump 3 may reach its upper limit, which is not conducive to the long-term and stable operation of the delivery pump 3; on the other hand, excessive pressure may lead to accidents such as pipe bursting and joint detachment, seriously affecting fire rescue. Therefore, to solve these shortcomings, the main difference between this embodiment 2 and the above embodiment 1 is that the supply module in the fire protection system provided in this embodiment also includes a pump pressure detection module 34, such as... Figure 7 As shown, the pump pressure detection module 34 can be set at the outlet of the delivery pump 3. The pump pressure detection module 34 is connected to the control module. For example, if the supply module is equipped with a second controller 33, the pump pressure detection module 34 can be directly connected to the second controller 33. The pump pressure detection module 34 is mainly used to detect the outlet water pressure of the delivery pump 3 and feed it back to the control module (such as the second controller 33).

[0043] like Figures 7-9As shown, the water gun also includes a prompting module 16 disposed on the water gun body 1. The prompting module 16 is communicatively connected to the control module. For example, if the water gun is equipped with a first controller 15, the prompting module 16 can be disposed on the outside of the water gun body 1, and the prompting module 16 can be directly connected to the first controller 15 so that the control module can control the prompting module 16. The battery in the power supply module is connected to the prompting module 16 to supply power to the prompting module 16.

[0044] In this embodiment, a pump pressure detection module 34 is configured to detect the actual outlet pressure of the delivery pump 3 and provide real-time feedback to the control module. The control module has a preset safety threshold for the outlet pressure of the delivery pump 3 (in practice, this safety threshold can be set according to actual needs to provide safety protection). Therefore, during actual use, the control module can continuously monitor whether the actual outlet pressure of the delivery pump 3 is higher than the set safety threshold. When the control module detects that the actual outlet pressure of the delivery pump 3 is equal to or higher than the set safety threshold, the control module automatically controls the prompting module 16 to activate, so as to provide a prompt... Module 16 serves as a reminder and warning to firefighters at the water nozzle, indicating that the actual water pressure of the delivery pump 3 has reached a safe threshold and cannot be further increased, or that the control module will no longer respond if the water pressure of the delivery pump 3 is further increased. On the one hand, this effectively prevents firefighters at the water nozzle from blindly adjusting the water pressure of the delivery pump 3, which could lead to excessive actual water pressure and cause accidents such as pipe bursting or joint detachment, seriously affecting fire rescue. This is especially suitable for situations where the fire scene is complex and the pipeline is long, resulting in a large pressure drop. On the other hand, it effectively protects the delivery pump 3 and the entire pipeline.

[0045] In implementation, the pump pressure detection module 34 can use an existing pressure sensor.

[0046] In implementation, the prompting module 16 can have various implementation methods. For example, the prompting module 16 may include a prompting light, such as... Figure 7 and Figure 8As shown, an indicator light is installed on the water nozzle body 1 and connected to a control module (such as the first controller 15). The control module can then change the state of the indicator light (e.g., on / off, flashing, etc.) to more clearly and promptly alert firefighters. In implementation, the indicator light can include one or more LED beads, or it can be a light strip. Alternatively, the indicator module 16 can also include a speaker, installed on the water nozzle body 1 and connected to the control module (such as the first controller 15). The control module can then change the speaker's state (e.g., on / off), allowing the speaker to play an alert tone to alert firefighters. Furthermore, the indicator module 16 can also include a vibrator, installed on the water nozzle body 1 and connected to the control module (such as the first controller 15). The control module can then change the vibrator's state (e.g., on / off) to alert firefighters.

[0047] To allow firefighters at the water gun to more intuitively understand the actual output pressure of the water gun and reduce reliance on their experience, in a further embodiment, the water gun also includes a gun pressure detection module 18 installed on the water gun body 1, such as... Figure 7 and Figure 8 As shown, the gun pressure detection module 18 can be installed at the water outlet 10 of the water gun body 1 and connected to the control module (such as the first controller 15). The gun pressure detection module 18 is mainly used to detect the actual output pressure of the water gun and feed it back to the control module (such as the first controller 15) with which it is communicatively connected. Correspondingly, the water gun also includes a display component 17 installed on the water gun body 1. The display component 17 can be installed on the outer side of the water gun body 1 or embedded in the housing of the water gun body 1, such as... Figure 8 As shown, the display component 17 can be an existing display device with display function, such as a display screen. The display component 17 is communicatively connected to the control module (such as the first controller 15) so that the display component 17 can display the actual output pressure of the water gun. Of course, in implementation, the display component 17 can also simultaneously display information such as the actual water pressure of the delivery pump 3. This not only allows firefighters to know the actual output pressure of the water gun at a glance, which is very simple and efficient, but also helps firefighters to conveniently and efficiently determine whether there is an abnormality in the pressure of the entire pipeline, thereby determining whether there is a fault in the pipeline.

[0048] In practice, the battery in the power supply module is connected to the display component 17 to supply power to the display component 17; in practice, the gun pressure detection module 18 can use an existing pressure sensor.

[0049] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
