[0045] The above preferred implementation modes are combined to obtain an optimal implementation mode. The corresponding solution is described as follows:

[0046] A clamp-type fire hydrant status data monitoring device includes a data collector 102 and a controller 105 connected to the data collector 102 via a cable 6. The data collector 102 includes a sensor integrator 2, a third sealing ring 1, and a first waterproof joint 5, which are embedded in a control cavity 3 of a housing 4 of the data collector 102 via a first sealing ring 2-4 and a second sealing ring 2-5. The sensor integrator 2 includes a magnetic switch 2-6, a water pressure sensor 2-7, a tipping sensor 2-8, a tongue plate 2-1, a magnet 2-2 embedded in the tongue plate 2-1, and a rotating shaft 2-3 for fixing the tongue plate 2-1. The tongue plate 2-1 can rotate up and down around the rotating shaft 2-3.

[0047] The controller 105 includes a waterproof joint 7 , an underground box cover 8 , an underground box 9 , a heat-insulating material 10 , a machine box cover 11 , a wireless transmission terminal DTU 12 , a battery 13 , and a machine box 14 .

[0048] In this embodiment, the data collector 102 is bolted between the water inlet flange of the fire hydrant 101 and the flange of the fire water supply pipe 103 and is buried vertically along with the fire hydrant. The intelligent controller 105 is buried next to the fire hydrant 101 and connected to the data collector 102 via a cable 6. The buried box cover 8 is flush with the ground to facilitate opening for maintenance.

[0049] The working principle of the above-mentioned clamp-type fire hydrant data monitoring device is as follows:

[0050] Water pressure monitoring, such as Figure 3 As shown, when water flows through the fire water supply pipe 103, the water pressure sensor 2-7 installed on the sensor integrator 2 of the data collector 102 will automatically detect the water pressure of the fire water supply and send the water pressure value of the fire water supply through the wireless transmission terminal DTU12 installed in the machine box 14 of the controller 105 according to the set data reporting frequency.

[0051] Opening and closing monitoring: When the fire hydrant 101 is opened, water begins to flow within the hydrant body. At this point, the tongue plate 2-1 on the sensor integrator 2 of the data collector 102 rotates upward under the action of the water flow. When the tongue plate 2-1 moves to a range where the magnet 2-2 embedded in the tongue plate 2-1 can trigger the magnetic switch 2-6, the magnetic switch 2-6 is triggered and turned on, and the wireless transmission terminal DTU12 transmits the corresponding information. When the fire hydrant 101 is closed and out of use, the water within the hydrant body stops flowing, and the tongue plate 2-1 rotates downward to its original position under the action of its own gravity. At this point, the magnet 2-2 embedded in the tongue plate 2-1 moves out of the range that triggers the magnetic switch 2-6, causing the magnetic switch 2-6 to turn off, and the wireless transmission terminal DTU12 transmits the corresponding information.

[0052] Collision and tipping monitoring: When the fire hydrant is violently vibrated or tipped by external force, the tipping sensor 2-8 set on the sensor integrator 2 of the data collector 102 is triggered, and the wireless transmission terminal DTU12 will send corresponding information.

[0053] The above describes in detail the preferred embodiments of the present invention. It should be understood that those skilled in the art can make numerous modifications and variations based on the concepts of the present invention without inventive effort. Therefore, any technical solutions that can be derived by those skilled in the art based on the concepts of the present invention through logical analysis, reasoning, or limited experimentation based on the existing technology should be within the scope of protection defined by the claims.
