Description

Technical Field

[0001] This application relates to the field of pressure monitoring devices, and more particularly to a pressure monitoring device for fire hydrants. Background Technology

[0002] As a key piece of equipment in the fire protection system, the stability of the internal water pressure of fire hydrants directly affects the fire extinguishing efficiency.

[0003] Currently, the main method for pressure monitoring on fire hydrant systems is to use mechanical pressure gauges, which are connected to flanges on the fire hydrant outlet pipes.

[0004] Mechanical pressure gauges rely primarily on manual reading and require periodic checks by maintenance personnel. In practice, when pressure gauge malfunctions during maintenance vacuum periods, timely repairs to the fire hydrant or pressure gauge are not possible, leading to reduced monitoring effectiveness and thus requiring improvement. Utility Model Content

A pressure sensor is provided on the support plate and extends into the through hole. A control component that cooperates with the pressure sensor is provided in the storage box.

[0008] By adopting the above technical solution, the control components and pressure sensors work together to achieve real-time monitoring of the pressure inside the fire hydrant wall, reducing the possibility of maintenance vacuum periods and thus improving the stability and timeliness of the pressure monitoring device during use.

The PCB board is connected to a pressure sensor via wires. The storage box contains a battery, and the battery is connected to the PCB board via a waterproof plug.

[0010] By adopting the above technical solution, the PCB board and antenna module form a wireless transmission module, which facilitates the collection and transmission of pressure sensor readings to the cloud for storage. The battery provides power to the control components and pressure sensor.

[0011] Preferably, the storage box is rotatably connected to a cover plate, and the cover plate is equipped with a display screen.

[0012] By adopting the above technical solution, the cover plate can easily protect the control components, while the display screen allows maintenance personnel to quickly read the pressure value of the inner wall of the fire hydrant.

[0014] By adopting the above technical solution, maintenance personnel rotate the connecting seat until it engages with the second connecting hole. They then install the nut on the connecting column, ensuring it is tightly against the flange, thus completing the installation between the support plate and the flange.

[0015] Preferably, the flange has a first sealing groove, in which a sealing ring is provided, and the support plate has a second sealing groove, in which the sealing ring extends into the second sealing groove.

[0016] By adopting the above technical solution, the sealing ring improves the sealing performance between the support plate and the flange.

[0017] Preferably, the support plate is provided with a protective shell, which is located in the through hole and covers the outside of the output end of the pressure sensor.

[0018] By adopting the above technical solution, the protective shell provides protection for the output end of the pressure sensor, reducing the possibility of impurities in the fire hydrant damaging the pressure sensor.

[0019] Preferably, the inner wall of the through hole is provided with a connecting ring, and the inner wall of the protective shell is threadedly connected to the outer wall of the connecting ring.

[0020] By adopting the above technical solution, the connecting ring can easily provide support for the protective shell, and the threaded connection makes it convenient for maintenance personnel to replace the protective shell later.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] 1. By setting up pressure sensors and control components, it is convenient to monitor the pressure in the fire hydrant pipeline in real time, reducing the possibility of maintenance vacuum periods, thereby improving the stability and timeliness of the pressure monitoring device during use;

[0023] 2. By providing a connection component, maintenance personnel can easily install the support plate onto the flange.

[0024] 3. By setting a protective shell, the detection end of the pressure sensor is protected, making it less susceptible to damage. Attached Figure Description

The support plate 2 is connected to the flange 1 and communicates with the flange 1 through a through hole 21. The storage box 3 is located on the side of the support plate 2 facing away from the flange 1. A pressure sensor 22 is installed on the support plate 2, extending into the through hole 21. A control component 4 that cooperates with the pressure sensor 22 is located in the storage box 3.

[0030] Reference Figure 1 The control component 4 includes a PCB board 41 and an antenna module 42. The PCB board 41 is housed in the storage box 3, and the antenna module 42 is mounted on the PCB board 41. The PCB board 41 is connected to the pressure sensor 22 via wires. A battery 31 is located in the storage box 3 and is connected to the PCB board 41 via a waterproof connector. The PCB board 41 and the antenna module 42 cooperate to form a wireless transmission module, which uses an NB-IoT communication chip.

[0031] Pressure sensor 22 collects water pressure signals in the fire hydrant in real time. After being converted into digital signals by PCB board 41, the signals are uploaded to the cloud platform via NB-IoT, realizing the function of real-time monitoring. This reduces the possibility of maintenance gaps and improves the monitoring stability and timeliness of the pressure monitoring device.

[0032] Reference Figure 1 A cover plate 32 is rotatably connected to the storage box 3, and a display screen 321 is provided on the cover plate 32. The display screen 321 is connected to the PCB board 41 through wires. The cover plate 32 provides protection for the control component 4, and the display screen 321 allows maintenance personnel to quickly read the internal pressure of the fire hydrant during manual maintenance.

[0033] Reference Figure 2 To facilitate the protection of the pressure sensor 22, a protective shell 5 is provided on the support plate 2.
