After the water monitoring structure Ⅰ1 is assembled, it can be screwed into the fire hydrant body 01 using threads, thereby improving the installation efficiency of the water monitoring structure.

[0054] Example 3

[0055] This embodiment proposes a specific implementation of a water monitoring structure based on Embodiment 1, such as... Figures 6-8 As shown, the water monitoring structure is water monitoring structure II2, the adapter is adapter II21, the electromagnetic water meter is electromagnetic water meter II22, and the toothed adapter is toothed adapter II23.

[0056] One end of adapter II21 is provided with an external thread, which is threaded to the threaded connector 02 of the fire hydrant body 01; the other end of adapter II21 is provided with an outwardly turned edge;

[0057] Electromagnetic water meter II22 has outward-curved edges at both ends; threaded adapter II23 has an outward-curved edge at one end and internal threads and threads at the other end.

[0058] The outward-facing edge of adapter II21 is coaxially aligned with the outward-facing edge of one end of electromagnetic water meter II22, and is fixedly connected by clamp I24; the outward-facing edge of threaded adapter II23 is coaxially aligned with the outward-facing edge of the other end of electromagnetic water meter II22, and is fixedly connected by clamp II25; the end cap 03 is threadedly connected to threaded adapter II23; the threads on threaded adapter II23 are used to connect fire hoses or other equipment.

[0060] Example 4

[0061] This embodiment proposes a specific implementation of a water monitoring structure based on Embodiment 1, such as...

[0066] Example 5

[0067] Based on any one of the embodiments 1-4, this embodiment provides a method for monitoring water usage in underground fire hydrants, as follows:

[0068] The electromagnetic water meter is also equipped with a central processing module, a pressure acquisition module, a flow acquisition module, and an abnormal alarm module.

[0069] The pressure acquisition module, flow acquisition module, abnormal alarm module, positioning module, and communication module can all communicate with the central processing module.

[0070] The pressure acquisition module collects the aforementioned pressure data from outlet I06 and transmits it to the central processing module;

[0071] The flow acquisition module collects the aforementioned water flow data from the underground fire hydrant flowing out of outlet I06, designates this water flow data as water flow data I, and transmits it to the central processing module;

[0072] The positioning module collects the positioning information data of underground fire hydrants and transmits it to the central processing module;

[0073] The central processing module transmits pressure data, water flow data, and location information data to the external back-end integrated management system via the communication module;

[0074] The central processing module also determines the operating status of the fire hydrant based on pressure data and water flow data. When the operating status is normal, the central processing module transmits the normal operating status data to the external background integrated management system through the communication module. When the operating status is abnormal, the central processing module transmits a control signal to the abnormal alarm module, and the abnormal alarm module alarms. At the same time, the central processing module also transmits the abnormal operating status data to the external background integrated management system.

[0075] In this embodiment, the electromagnetic water meter is also equipped with a central processing module, an abnormal alarm module, and a positioning module. The central processing module can determine the operating status of the fire hydrant based on pressure data and water flow data. The abnormal alarm module can sound an alarm when the water flow from the fire hydrant is abnormal. The positioning module can locate the fire hydrant in a timely manner, which facilitates timely troubleshooting of the fire hydrant and ensures fire safety.

[0076] Furthermore, the central processing module can also calculate other water outlets on the fire hydrant (such as those shown in the attached diagram) based on the pressure data. Figure 1 The water flow data II of outlet II07 is obtained. Specifically, the central processing module calculates the approximate water volume as water flow data II based on the initial pressure data at the time of water discharge and the pressure change value and rate of change during the process until the flow stabilizes, combined with the pressure change time. The water flow data II is then transmitted to the background integrated management system through the communication module.

[0077] Furthermore, the central processing module can be pre-set to establish a correlation model between pressure changes and flow rate based on big data analysis, and calculate the effluent flow rate data II based on this model.

[0078] This embodiment provides a method for monitoring water usage and status of underground fire hydrants with dual outlets in northern regions. By installing a water usage and pressure monitoring device on only one outlet of the fire hydrant, the flow rate of all outlets of the fire hydrant can be monitored. This eliminates the need to install monitoring water meters at all outlets of the fire hydrant, saving costs and improving the efficiency of smart fire hydrant upgrades.

[0079] Furthermore, the central processing module determines the operating status of the fire hydrant based on pressure data and water flow rate data I as follows:

[0080] The central processing module compares the received pressure data with a preset threshold:

[0081] When the pressure data is not less than the threshold and the water flow rate data is equal to zero, the central processing module determines that the fire hydrant is operating normally.

[0082] Outside of normal operating conditions during a fire, when the pressure data is less than the threshold and the water flow rate is greater than zero, the central processing module determines that water is flowing from outlet I06 and that the fire hydrant's operating status is abnormal.

[0083] Outside of normal operating conditions during a fire, if the pressure data is below the threshold and the water flow rate is zero, water may flow from other outlets on the fire hydrant, as shown in the attached diagram. Figure 1 If the water outlet II07 in the fire hydrant is faulty, or if there is a problem with the water supply to the fire hydrant, the central processing module will determine that the fire hydrant is in an abnormal operating state.

[0084] In this embodiment, a water usage monitoring structure is installed on only one outlet of the fire hydrant to achieve status monitoring of all outlets. This allows for both positive judgment of the water flow status of the corresponding outlet and judgment of whether other outlets are abnormal. It eliminates the need to install monitoring water meters at all outlets of the fire hydrant, saving costs and improving the update efficiency of smart fire hydrants.

[0085] In summary, the above are merely preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
