[0043] Typical embodiments embodying the features and advantages of this disclosure will be described in detail in the following description. It should be understood that this disclosure can have various variations in different embodiments without departing from the scope of this disclosure, and the descriptions and drawings therein are illustrative in nature and not intended to limit this disclosure.

[0044] In the following description of various exemplary embodiments of this disclosure, reference is made to the accompanying drawings, which form part of this disclosure, and which illustrate by way of example different exemplary structures, systems, and steps that can implement various aspects of this disclosure. It should be understood that other specific embodiments of the components, structures, exemplary devices, systems, and steps may be used, and structural and functional modifications may be made without departing from the scope of this disclosure. Furthermore, while the terms “above,” “between,” “within,” etc., may be used in this specification to describe different exemplary features and elements of this disclosure, these terms are used herein only for convenience, such as the orientation according to the examples described in the accompanying drawings. Nothing in this specification should be construed as requiring a specific three-dimensional orientation of the structure to fall within the scope of this disclosure.

[0045] See Figure 1 The illustration represents a schematic diagram of the water supply system proposed in this disclosure. In this exemplary embodiment, the water supply system proposed in this disclosure is described using an application to a fire truck as an example. It will be readily understood by those skilled in the art that various modifications, additions, substitutions, deletions, or other changes may be made to the specific embodiments described below in order to apply the relevant designs of this disclosure to other types of fire-fighting equipment, and these changes shall still be within the scope of the principles of the water supply system proposed in this disclosure.

[0046] like Figure 1As shown, in one embodiment of this disclosure, the water supply system proposed in this disclosure is installed on a fire truck. The water supply system includes a water storage container 100, a foam container 200, a fire pump 300, and water-using components. See also... Figure 2 , Figure 2 The accompanying drawings illustrate a schematic diagram of the display graphics of the display device 510, which represents the principles of this disclosure for a water supply system. The text and numbers displayed are merely illustrative and not intended to be limiting. The structure, connection methods, and functional relationships of the main components of the water supply system proposed in this disclosure will be described in detail below with reference to the accompanying drawings.

[0047] like Figure 1As shown, in one embodiment of this disclosure, the water storage container 100 is used for storing water, and the water storage container 100 can be, for example, a water tank. The foam container 200 is used for storing foam, and the foam container 200 can be, for example, a foam tank. The inlet of the fire pump 300 is connected to the water storage container 100 via an inlet pipe 410, and the outlet of the fire pump 300 is connected to the water-using component via an outlet pipe 420. The foam container 200 is connected to the inlet pipe 410 via a foam delivery pipe 430, and an automatic control valve 431 is installed on the foam delivery pipe 430. The foam delivery pipe 430 is connected to an emergency pipe 440, and the two ends of the emergency pipe 440 are respectively connected to the inlet side and the outlet side of the automatic control valve 431 of the foam delivery pipe 430. That is, the emergency pipe 440 (and the first flow meter 441 and the manual control valve 442 installed thereon) and the aforementioned part of the foam delivery pipe 430 where the automatic control valve 431 is installed are connected in parallel. The emergency pipeline 440 is equipped with a first flow meter 441 and a manual control valve 442. The first flow meter 441 is used to collect the flow information of the emergency pipeline 440, and the manual control valve 442 is used to regulate the flow of the emergency pipeline 440. The emergency pipeline 440 can be understood as a bypass pipeline, and the manual control valve 442 as a manually adjustable bypass valve. Accordingly, the foam delivery pipeline 430 can serve as the main pipeline for delivering foam to the water supply system. For example, when the automatic control valve 431 is functioning normally, the water supply system can deliver foam solely through the foam delivery pipeline 430, i.e., by opening the automatic control valve 431, without needing to open the manual control valve 442. The emergency pipeline 440 can then serve as a backup pipeline for delivering foam to the water supply system. For example, if the automatic control valve 431 fails, the manual control valve 442 can be opened and adjusted to achieve foam delivery. Through the above structural design, this disclosure utilizes the emergency pipeline 440 and the manual control valve 442 to provide emergency protection for the foam mixing function of the water supply system. When the automatic control valve 431 fails to operate, foam can be delivered and mixed by controlling the manual control valve 442, and the foam ratio can be adjusted by regulating the manual control valve 442. Furthermore, this disclosure uses a first flow meter 441 to collect the flow information of the emergency pipeline 440, providing this flow information to the user for reference and as a basis for adjusting the manual control valve 442. This makes the adjustment of the foam delivery ratio in emergency mode more precise, avoiding the drawbacks of relying solely on experience for visual control without objective parameter references.

[0048] Specifically, taking a fire truck as an example, water-using components can include water cannons and water nozzles. Furthermore, water nozzle applications can include single-nozzle and multi-nozzle applications. Based on this, compared to the larger flow rate of the automatic control valve 431, the manual control valve 442 typically has a smaller lower limit for flow regulation. In this case, the manual control valve 442 can be used to achieve single-nozzle applications requiring a smaller flow rate. For example, when single-nozzle application is needed, the automatic control valve 431 can be closed, the manual control valve 442 opened, and the emergency pipeline 440 can be used for foam delivery to meet the low-flow-rate liquid supply requirements.

[0049] like Figure 1 and Figure 2 As shown, in one embodiment of this disclosure, a second flow meter 421 may be installed on the outlet pipe 420. This second flow meter 421 is used to collect flow information from the outlet pipe 420, and the flow rate of the pure water pipe is the total flow rate of the mixture after mixing with foam. Furthermore, the water supply system proposed in this disclosure may also include an interactive module, which connects the first flow meter 441 and the second flow meter 421. The flow information collected by the first flow meter 441 and the second flow meter 421 is displayed on the display device 510. Through the above structural design, this disclosure allows the operator to know the outlet flow rate of the outlet pipe and the flow rate of the foam in the emergency pipe, thereby more intuitively understanding the proportion of foam in the total outlet water volume, and more accurately controlling the manual control valve 442 based on this information.

[0050] like Figure 2 As shown, based on the structural design of the water supply system including an interactive module, in one embodiment of this disclosure, the interactive module may be equipped with a processing unit. This processing unit is used to calculate the flow ratio of foam in the water in the outlet pipe 420 based on the flow information collected by the first flow meter 441 and the second flow meter 421. Through the above structural design, this disclosure allows the operator to know the flow ratio of foam in the outlet pipe, intuitively understand the proportion of foam in the total outflow, and more accurately control the manual control valve 442 based on this.

[0051] Based on the design of displaying the flow information collected by the first flow meter 441 and the second flow meter 421 on the display device 510, in one embodiment of this disclosure, the fire truck may include a main display screen and a secondary display screen, which may be located on both sides of the fire truck. The flow information collected by the first flow meter 441 and the second flow meter 421 can be displayed on the secondary display screen. Through the above structural design, this disclosure arranges the main display screen and the secondary display screen displaying the flow information on both sides of the fire truck. The manual control valve 442 can be arranged on the opposite side of the main display screen, that is, the manual control valve 442 and the secondary display screen are located on the same side of the fire truck, thereby facilitating the operator to obtain the flow information from the secondary display screen when controlling the manual control valve 442. In other embodiments of this disclosure, the fire truck may include a main display screen, on which the flow information collected by the first flow meter 441 and the second flow meter 421 can be displayed. This integrates the data display function of the interactive module into the main display screen of the fire truck, which helps to reduce the number of parts and lower costs.

[0052] like Figure 1 As shown, in one embodiment of this disclosure, a third flow meter 422 may be installed on the outlet pipe 420. This third flow meter 422 is used to collect flow information from the outlet pipe 420. Based on this, an automatic control valve 431 can be connected to the third flow meter 422. The control unit of the automatic control valve 431 controls the automatic control valve 431 according to the flow information collected by the third flow meter 422. Through the above structural design, this disclosure can achieve closed-loop control of the foam delivery pipe 430 by the automatic control valve 431, further improving the degree of automation and enhancing the sensitivity and accuracy of flow control over the foam delivery pipe 430.

[0053] like Figure 1 As shown, in one embodiment of this disclosure, a foam mixing pipeline 450 can be connected between the water outlet pipeline 420 and the foam delivery pipeline 430. This foam mixing pipeline 450 connects the portion of the water outlet pipeline 420 located between the emergency pipeline 440 and the inlet pipeline 410. A foam mixing valve 451 is provided on the foam mixing pipeline 450. Through the above structural design, this disclosure can achieve thorough mixing of foam and water using the foam mixing pipeline 450. For example, before the foam mixture is output to the water-using component, the screen mixture can be circulated in the loop formed by the foam mixing pipeline 450, the foam delivery pipeline 430, the inlet pipeline 410, and the water outlet pipeline 420 for a certain period of time, thereby allowing the foam and water to mix more thoroughly.

[0054] like Figure 1As shown, based on the structural design of the water supply system including the foam mixing pipeline 450, in one embodiment of this disclosure, the water supply system proposed in this disclosure may further include a Venturi tube 460, one inlet of which is connected to the portion of the foam delivery pipeline 430 that is connected to the emergency pipeline 440, the other inlet of which is connected to the foam mixing pipeline 450, and the outlet of which is connected to the portion of the foam delivery pipeline 430 that is connected to the inlet pipeline 410.

[0055] like Figure 1 As shown, based on the structural design of the water supply system including the foam mixing pipeline 450, in one embodiment of this disclosure, a foam cleaning pipeline 470 can be connected between the foam mixing pipeline 450 and the foam delivery pipeline 430. The foam cleaning pipeline 470 connects the portion of the foam delivery pipeline 430 located between the foam container 200 and the emergency pipeline 440. A foam cleaning valve 471 is provided on the foam cleaning pipeline 470. Through the above structural design, this disclosure can utilize the foam cleaning pipeline 470 to achieve the function of circulating cleaning of pipelines such as the foam delivery pipeline 430 and the emergency pipeline 440.

[0056] like Figure 1 As shown, in one embodiment of this disclosure, a liquid outlet valve 432 and a check valve 433 may be provided on the portion of the foam delivery pipeline 430 located between the foam container 200 and the emergency pipeline 440. The liquid outlet valve can control the overall output state of the foam liquid from the foam container 200, such as opening / closing or regulating the flow rate. The check valve 433 can prevent foam liquid backflow.

[0057] It should be noted that the water supply systems shown in the accompanying drawings and described in this specification are merely a few examples of many water supply systems to which the principles of this disclosure can be applied. It should be clearly understood that the principles of this disclosure are by no means limited to any detail or component of the water supply systems shown in the accompanying drawings or described in this specification.

[0058] Based on the above detailed description of several exemplary embodiments of the water supply system proposed in this disclosure, an exemplary embodiment of the fire truck proposed in this disclosure will be described below.

It should be clearly understood that the principles of this disclosure are by no means limited to any detail or component of the fire trucks shown in the accompanying drawings or described in this specification.

[0061] In summary, the water supply system proposed in this disclosure includes an emergency pipeline 440, which is arranged in parallel with the foam delivery pipeline 430. The emergency pipeline 440 is equipped with a first flow meter 441 and a manual control valve 442. The first flow meter 441 is used to collect the flow information of the emergency pipeline 440, and the manual control valve 442 is used to regulate the flow of the emergency pipeline 440. Through the above structural design, this disclosure utilizes the emergency pipeline 440 and the manual control valve 442 to provide emergency protection for the foam mixing function of the water supply system. When the automatic control valve 431 fails to operate, foam delivery and mixing can be achieved by controlling the manual control valve 442, and the foam ratio can be adjusted by regulating the manual control valve 442. Furthermore, this disclosure uses the first flow meter 441 to collect the flow information of the emergency pipeline 440, providing this flow information for user reference as a basis for adjusting the manual control valve 442. This makes the adjustment of the foam delivery ratio in emergency mode more precise, avoiding the drawbacks of relying solely on experience without objective parameter references during visual control.
