[0047] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0048] Embodiment 1:

[0049] like Figure 1 As shown, this embodiment provides an intelligent monitoring component for a fire hydrant, including: a component housing 100, a first support rod 500, a water consumption detection component 600, a controller 700 and a communication module 800.

[0050] The assembly housing 100 is installed between the fire hydrant cover 200 and the fire hydrant body 300 , and the assembly housing 100 is provided with an avoidance hole allowing the valve stem 400 to pass through, and the assembly housing 100 is also provided with a shell cavity.

[0051] The assembly housing 100 can be removed from the fire hydrant, specifically: first remove the connection piece between the fire hydrant cover 200 and the assembly housing 100, and then remove the fire hydrant cover 200 from the assembly housing 100; then remove the connection piece between the assembly housing 100 and the fire hydrant body 300, and then remove the assembly housing 100 from the fire hydrant body 300. There is no force between the avoidance hole of the assembly housing 100 and the valve stem 400, and the assembly housing 100 can directly move up and down relative to the valve stem 400. If a valve stem rotation auxiliary part 410 is provided at the top of the valve stem 400, it is only necessary to first detach the valve stem rotation auxiliary part 410 from the valve stem 400.

[0052] The axial top end of the first support rod 500 is connected to the component housing 100 , and the first support rod 500 is provided with a first threading hole arranged along the length direction thereof and communicating with the housing cavity.

[0053] The water consumption detection component 600 is connected to the axial bottom end of the first support rod 500 .

[0054] The controller 700 is disposed in the shell cavity, and the controller 700 is connected to the water consumption detection component 600 via a first connecting line arranged in the first threading hole.

[0055] The communication module 800 is disposed in the shell cavity, and the controller 700 is wirelessly connected to the monitoring platform through the communication module 800. The communication module 800 may be an NB-IoT communication module. The water consumption detection component 600 sends a detection signal to the controller 700, and the controller 700 sends the detection signal to the monitoring platform, and the monitoring platform can calculate the water consumption of the fire hydrant according to the detection signal.

[0056] In this embodiment, the water consumption detection component 600 is not directly installed on the fire hydrant, but the water consumption detection component 600, the controller 700, the component housing 100 and other components are first integrated into an intelligent monitoring component, and then the intelligent monitoring component is connected to the fire hydrant. The disassembly and assembly operation of the intelligent monitoring component and the fire hydrant is very simple, which makes the disassembly and assembly operation of the water consumption detection component 600 very simple.

[0057] Further, such as Figure 2 and Figure 3 As shown, the component housing 100 includes: a main annular body 110, a sub-annular body 120, an annular bottom plate 130, a top annular wing plate 140 and a bottom annular wing plate 150 which are integrally formed.

[0058] The central axis of the sub-annular body 120 is the same as the central axis of the main annular body 110, and a relief hole is formed in the sub-annular body 120. The relief hole is used for the valve stem 400 to pass through.

[0059] The outer ring side of the annular bottom plate 130 is connected to the axial bottom end of the main annular body 110, and the inner ring side of the annular bottom plate 130 is connected to the axial bottom end of the sub-annular body 120. The annular bottom plate 130, the sub-annular body 120, and the main annular body 110 form a shell cavity. The shell cavity is used to install components such as the controller 700 and the communication module 800.

[0060] The top annular wing plate 140 is connected to the axial top end of the main annular body 110. The top annular wing plate 140 is used to connect to the annular wing plate of the fire hydrant cover body 200.

[0061] The bottom annular wing plate 150 is connected to the axial bottom end of the main annular body 110. The bottom annular wing plate 150 is used to be connected to the annular wing plate of the fire hydrant body 300.

[0062] When the component housing 100 is connected to the fire hydrant, it is only necessary to first pass the avoidance hole of the sub-annular body 120 through the valve stem 400, and then move the component housing 100 downward until the bottom annular wing plate 150 contacts the annular wing plate of the fire hydrant body 300 and use connecting parts (such as bolts and nuts) to connect and fix the bottom annular wing plate 150 to the annular wing plate of the fire hydrant body 300, and then place the annular wing plate of the fire hydrant cover body 200 on the top annular wing plate 140 and use connecting parts to connect and fix the annular wing plate of the fire hydrant cover body 200 to the top annular wing plate 140.

[0063] Since the first support rod 500, the water consumption detection component 600, the controller 700 and other components are fixedly mounted on the assembly housing 100, when the assembly housing 100 is connected to the fire hydrant, the water consumption detection component 600 is also installed. In addition, since the assembly housing 100 of the present embodiment is very easy to disassemble and assemble with the fire hydrant, the water consumption detection component 600 is also very easy to disassemble and assemble with the fire hydrant.

[0064] Further, such as Figure 2 As shown, the component housing 100 further includes an annular top plate 160 .

[0065] The outer ring side of the annular top plate 160 is detachably connected to the axial top end of the main annular body 110, and the inner ring side of the annular top plate 160 is detachably connected to the axial top end of the sub-annular body 120. The annular top plate 160 is mainly used to seal the shell cavity, thereby protecting the controller 700 and other components in the shell cavity.

[0066] The axial top end of the main annular body 110 is provided with a limiting support part 1 at the connection between its top surface and the inner side surface, and the limiting support part 1 includes a vertical limiting surface 1 and a horizontal supporting surface 1. The axial top end of the sub-annular body 120 is provided with a limiting support part 2 at the connection between its top surface and the outer side surface, and the limiting support part 2 includes a vertical limiting surface 2 and a horizontal supporting surface 2. The annular top plate 160 can be directly placed on the horizontal supporting surface 1 and the horizontal supporting surface 2 and limited in the horizontal direction by the vertical limiting surface 1 and the vertical limiting surface 2.

[0067] Magnetic layers are provided on the horizontal support surface 1 and the horizontal support surface 2, and magnetic docking layers are provided on the top and bottom surfaces of the annular top plate 160. When installing the annular top plate 160, it is only necessary to place the annular top plate 160 on the horizontal support surface 1 and the horizontal support surface 2, and the annular top plate 160 is connected and fixed to the main annular body 110 and the sub-annular body 120 by magnetic attraction. When the annular top plate 160 needs to be disassembled, it is only necessary to lift the annular top plate 160 by a magnetic attraction tool.

[0068] Further, such as Figure 2 , Figure 3 and Figure 5 As shown, the water consumption detection component 600 of this embodiment includes: a first housing 610 , a Hall sensor, a second housing 620 , an impeller 630 and a magnet 640 .

[0069] The first housing 610 is connected to the axial bottom end of the first support rod 500. The shape of the first housing 610 may be a cube. The first support rod 500 is sealedly connected to the top surface of the first housing 610, and only the first connecting wire is allowed to enter the first housing 610 through the first threading hole.

[0070] The Hall sensor is disposed in the cavity of the first housing 610 , and the Hall sensor is connected to the first connecting line. The Hall sensor is connected to the first vertical side surface of the first housing 610 .

[0071] The second housing 620 is connected to the first housing 610, and the second housing 620 is provided with a water inlet 621 and a water outlet 622 in the vertical direction. The second housing 620 may be in the shape of an oblate cylinder, and the central axis of the oblate cylinder is arranged horizontally. Figure 2 The water inlet 621 is in a circular tube shape and connected to the lower part of the peripheral side surface of the second housing 620, and the water outlet 622 is also in a circular tube shape and connected to the upper part of the peripheral side surface of the second housing 620. The cavity of the second housing 620 is in communication with the water inlet 621 and the water outlet 622.

[0072] The impeller 630 is disposed in the cavity of the second housing 620, and the impeller 630 is rotatably connected to the second housing 620 via a rotating shaft. During the use of fire-fighting water, part of the water flow will enter the cavity of the second housing 620 from the water inlet 621, and then flow out from the water outlet 622. When the water flows through the second housing 620, it will drive the impeller 630 to rotate.

[0073] The magnet 640 is connected to the impeller 630 , and the magnet 640 is non-contactly connected to the Hall sensor every time the impeller 630 rotates one circle.

[0074] When the impeller 630 rotates to the point where the magnet 640 is located at the right side of the first circular side surface of the second housing 620 (at Figure 2 ), the Hall sensor detects the magnet 640 and obtains a detection signal (when the magnet 640 rotates to other positions, the Hall sensor cannot detect the magnet 640). When the impeller 630 rotates one more circle until the magnet 640 is located at the right side of the first circular side surface of the second housing 620, the Hall sensor detects the magnet 640 again and obtains a detection signal. In short, the Hall sensor obtains a detection signal every time the impeller 630 rotates one circle.

[0075] The controller 700 will send these detection signals to the monitoring platform. The monitoring platform can obtain the number of rotations of the impeller 630 per unit time through the detection signals, and then determine the flow rate of the fire water (specifically how to calculate the flow rate through the number of rotations directly adopts the existing technology), and finally calculate the water consumption of the fire hydrant.

[0076] Further, such as Figure 5 As shown, the impeller 630 of this embodiment includes: a rotating shaft sleeve 631 and blades 632.

[0077] The rotating shaft sleeve 631 is assembled and connected to the rotating shaft.

[0078] A plurality of blades 632 are connected to the outer circumference of the rotating sleeve 631, and each blade 632 includes an arc plate and a straight plate connecting the arc plate and the rotating sleeve. In this embodiment, the arc of the arc plate can be 180 degrees, and the impeller 630 can be provided with four blades 632.

[0079] The water inlet 621 and the water outlet 622 are arranged in the same vertical direction, and the water inlet 621 faces the inner arc surface of the arc plate. The water flow channel is arranged to align with the blade 632, so that the water flow can just push the blade 632 to rotate.

[0080] Further, such as Figure 6 As shown, the impeller 630 further includes a magnet socket 633 .

[0081] The magnet plug-in sleeve 633 is embedded in the inner arc surface of the arc plate of one of the blades 632, and the magnet plug-in sleeve 633 is provided with a magnet plug-in interface, and the magnet 640 is provided with a magnet plug-in portion assembled and connected with the magnet plug-in interface. The magnet plug-in interface is arranged toward the Hall sensor, and after the magnet 640 is installed, when the impeller 630 rotates to a certain position, the magnet 640 can be very close to the Hall sensor, thereby enabling the magnet 640 and the Hall sensor to be non-contactly docked. The arrangement of the magnet plug-in sleeve 633 makes the magnet 640 easy to install.

[0082] In addition, when there is no water in the fire hydrant or the water is not flowing, the blade 632 provided with the magnetic socket 633 and the magnet 640 can rotate to the bottom by its own gravity. At this time, the magnet 640 is offset from the Hall sensor, and the Hall sensor will not obtain the detection signal.

[0083] Further, such as Figure 1 and Figure 2 As shown, the intelligent monitoring component of this embodiment further includes: a second support rod 910 and a water level sensor 920 .

[0084] The axial top end of the second support rod 910 is connected to the component housing 100 , and the second support rod 910 is provided with a second threading hole arranged along the length direction thereof and communicating with the housing cavity.

[0085] The water level sensor 920 is connected to the axial bottom end of the second support rod 910, and the controller 700 is connected to the water level sensor 920 via a second connecting line arranged in the second threading hole.

[0086] The water level sensor 920 is used to detect the water level of the fire water in the fire hydrant. In this embodiment, the water level sensor 920 can be set above the water outlet of the fire hydrant. When the water level sensor 920 detects a signal, it means that there is too much fire water in the fire hydrant (if there is more fire water, the fire hydrant may burst, or the fire water may flow back into the shell cavity of the component housing 100). At this time, the drain valve 310 can be controlled to open to discharge the excess fire water.

[0087] The intelligent monitoring component of this embodiment can be installed with not only the water consumption detection component 600, but also other detection components, such as a water level sensor 920, so that the monitoring function of the intelligent monitoring component is more diverse and comprehensive.

[0088] Embodiment 2:

[0089] like Figure 4 As shown, this embodiment provides an intelligent monitoring component for a fire hydrant, which is different from the intelligent monitoring component in Example 1 in that the component housing 100 in this embodiment further includes: a heightening rod 170 and a sub-housing 180 .

[0090] The height-increasing rod 170 is connected to the outer peripheral side of the main annular body 110. The height-increasing rod 170 can be adjusted in height according to the use requirements, and can be fixed after the height is adjusted.

[0091] The sub-shell 180 is connected to the top of the heightening rod 170, the communication module 800 is arranged in the sub-shell cavity of the sub-shell 180, and the heightening rod 170 is provided with a wire hole arranged along its length direction and connecting the shell cavity and the sub-shell cavity.

[0092] In this embodiment, the communication module 800 is not installed in the housing cavity, but in the sub-housing cavity of the sub-housing 180. In this embodiment, the installation position of the communication module 800 is increased by the arrangement of the sub-housing 180 and the heightening rod 170, thereby making the communication effect between the communication module 800 and the monitoring platform better.

[0093] Embodiment 3:

[0094] This embodiment provides a fire hydrant, including the intelligent monitoring component for fire hydrants in Embodiment 1 or Embodiment 2.

[0095] The above embodiments are only for describing the preferred implementation of the utility model, and are not intended to limit the concept and scope of the utility model. Without departing from the design concept of the utility model, various modifications and improvements made by ordinary persons in the art to the technical solution of the utility model should fall within the protection scope of the utility model, and the technical contents of the utility model for protection have been fully recorded in the claims.
