Therefore, the following detailed description of the embodiments of the present utility model provided in the drawings is not intended to limit the scope of the present utility model to be protected, but merely represents the selected embodiments of the present utility model.

[0028] In the description of the present utility model, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present utility model, "a plurality" means two or more unless otherwise specifically defined.

[0029] Currently, for detection, it is usually necessary for workers to manually open the fire hydrant to understand the current working state of the fire hydrant, which consequently results in a large amount of time being consumed by the staff during the inspection and maintenance process. Therefore, to solve the above problems, the following technical solutions are proposed in this case:

[0030] Refer to Figures 1 to 4As shown in the figure, an intelligent fire hydrant includes: a hydrant body 3, a top cover 2 on the top of the hydrant body 3, an end cover 4 on the side of the hydrant body 3 for port closing, a base 5 is also installed at the bottom of the hydrant body 3, and a closing part 1 for controlling the opening and closing of the cavity is arranged inside the hydrant body 3. The closing part 1 includes a locking rod 11 engaged with the top cover 2, and a drain valve 15 installed on the side of the hydrant body 3. A connecting sleeve 12 is also provided at the bottom of the locking rod 11. A second valve plate 16 is nested inside the connecting sleeve 12. The connecting sleeve 12 is fixed on the top of the first valve plate 14. A slot hole for cooperating with the second valve plate 16 is also provided in the middle of the first valve plate 14. The slot hole and a diversion hole 13 opened on the side of the connecting sleeve 12 form a flow channel. A control box 7 connected to the second valve plate 16 is also provided on the surface of the hydrant body 3.

[0031] In this embodiment, the device includes a base 5 installed on the pipeline. The hydrant body 3 is arranged on the top of the base 5. A closing part 1 is installed inside the hydrant body 3 to control the on-off of the water flow in the pipeline. An end cover 4 installed at the pipe orifice of the hydrant body 3 is used to protect the pipe orifice. The closing part 1 cooperates with a threaded block inside the top cover 2. A control box 7 is also installed on the side of the hydrant body 3. A remote controller is installed inside the control box 7 for remote communication, which is convenient for personnel to supervise.

[0032] The structure of the closing part 1 includes a locking rod 11 cooperating with the top cover 2. The bottom of the locking rod 11 is connected to a connecting sleeve 12, and the first valve plate 14 at the bottom is connected through the connecting sleeve 12 to control the port inside the base 5. In order to facilitate the detection of the inside of the pipeline and clean the periphery of the first valve plate 14 regularly, a second valve plate 16 is arranged in the middle of the first valve plate 14.

[0033] The second valve plate 16 cooperates with a through hole in the middle of the first valve plate 14. At the same time, a diversion hole 13 is provided on the side of the connecting sleeve 12. The diversion hole 13 cooperates with the hole of the first valve plate 14. When the second valve plate 16 is opened, the liquid inside the pipeline enters the inside of the connecting sleeve 12 through the hole of the first valve plate 14, and then flows out through the diversion hole 13 and seeps out at the drain valve 15. In order to improve the intelligence, a liquid detection sensor is integrated in the drain valve 15. When the liquid passes through, the electrodes between the sensors are conducted, and then an electric signal is sent to the control box 7 to judge the current state of the fire hydrant. It can not only be detected during maintenance, but also prevent theft to avoid someone deliberately opening the fire hydrant. And in order to avoid the fixed bolts of the base 5 being corroded by seepage during detection, a diversion groove 6 is also provided on the side of the base � for diversion to the outside.

[0034] The structure of the second valve plate 16 includes a control valve 161. Specifically, the control valve 161 adopts an electric push rod structure, and a sleeve is provided outside the screw rod for telescoping to protect the internal screw rod.

[0035] The control valve 161 is connected to the bottom plate 162. On the surface of the bottom plate 162, a retaining ring 166 extends outward. The retaining ring 166 is provided with a notch to cooperate with the diversion block 165 with a middle inclined surface for diversion. When opening and closing, the pressure can be reduced through the inclined surface. And in order to prevent the rubber ring 164 nested in the bottom plate 162 from being damaged and accelerated by contacting with water flow, a protective ring 163 is installed between the rubber ring 164 and the notch of the retaining ring 166. The protective ring 163 fixes the edge of the rubber ring 164 and prevents the water flow from scouring the gap and causing damage to the rubber ring 164.

[0036] The detection method of this device is as follows:

[0037] During daily use, the locking rod 11 drives the first valve plate 14 to close the port. At this time, the sensor of the drain valve 15 does not detect liquid, and the signal is in the closed state. The control box 7 will regularly transmit the signal to the master control room through the communication module.

[0038] In order to detect whether there is water in the current pipeline, it can not only be detected according to the water pressure in the pipeline, but also be started through the control valve 161. The bottom plate 162 is separated from the hole in the middle of the first valve plate 14, and the water flow passes through the diversion hole 13 and flushes back into the inside of the bolt body 3 and then flows through the drain valve 15. At this time, after the sensor detects the water flow, the internal electrode conducts and transmits the signal to the control box 7, and the control box 7 gives feedback, thereby achieving the purpose of detection.

[0039] And there are protrusions on the inner surface of the bolt body 3 for reference Figure 2 When the water flow is large, it impacts with the protrusions inside the bolt body 3, and then flushes back around the first valve plate 14 to wash the periphery of the first valve plate 14, so that the first valve plate 14 is in a good working state and avoids long-term corrosion caused by rust attachment.

[0040] The improved device controls the small-range flow of the liquid suppressed by the first valve plate 14 through the second valve plate 16, cooperates with the drain valve 15 without opening the first valve plate 14, remotely detects the liquid inside the pipeline through the sensor, and cooperates with the pipeline network water pressure sensor to further improve the accuracy.

[0041] And a diversion block 165 is arranged inside the retaining ring 166 for diversion on the surface of the bottom plate 162. Through the diversion block 165, the pressure during opening and closing can be reduced. When opening, it cooperates with the diversion hole 13 on the side of the connecting sleeve 12 to wash and clean the periphery of the bolt body 3 and the first valve plate 14, and improve the overall service life.

[0042] Only the basic principle and preferred implementation mode of the present utility model are described above. Those skilled in the art can make many changes and improvements according to the above description, and these changes and improvements should belong to the protection scope of the present utility model.

[0043] In addition, it should be understood that although this specification is described in terms of embodiments, not every embodiment contains only an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
