Description

Technical Field

[0001] This utility model relates to the field of fire protection technology, and in particular to a smart fire hydrant. Background Technology

[0002] Fire hydrants, as the core infrastructure of urban public fire protection systems, are widely distributed in various areas such as urban streets, residential communities, and industrial parks. Their functional integrity directly determines the efficiency of fire fighting and even affects the final success or failure of fire rescue. They are a key link in ensuring urban fire safety.

[0003] Currently, traditional fire hydrants generally adopt a purely mechanical structure design, and their operational status monitoring and daily maintenance rely entirely on firefighters or dedicated administrators for regular manual inspections. This operation and maintenance model has significant drawbacks, specifically in the following two aspects: First, the inspection cycle is long and costly, and real-time monitoring is not possible. During the interval between two inspections, fire hydrants may experience insufficient water pressure, leaks, theft, or damage, which may not be detected in time, posing a huge safety hazard. Second, there are no protective measures for key components of fire hydrants (such as valve actuators), which can be easily opened illegally, resulting in water loss. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a smart fire hydrant to solve the problems mentioned above in the background technology.

[0005] On the one hand, the utility model provides the following technical solution: a smart fire hydrant, including a fire hydrant body, a protective component detachably mounted on the valve drive rod at the top of the fire hydrant body, and a monitoring device detachably mounted on the fire hydrant body; The monitoring device includes a housing, a control module disposed inside the housing, and a water pressure sensor electrically connected to the control module. The protective component includes a protective shell, a protective cover hinged to the protective shell, a connecting buckle provided on the protective cover, a limiting part provided on the protective shell, and a reset part that drives the limiting part to move toward or away from the connecting buckle. The reset part is used to lock or release the connecting buckle by the limiting part.

[0006] Compared to existing technologies, the advantages of this application are as follows: By setting up monitoring equipment connected to a water pressure sensor and control module, the internal water pressure of the fire hydrant can be continuously and in real time monitored. This effectively solves the drawbacks of traditional manual inspection methods, such as long cycles, high costs, and inability to detect problems in a timely manner. Once water pressure abnormalities occur (such as insufficient or excessive pressure), it provides a reliable water source for fire fighting and facilitates timely detection of leaks or theft by management personnel. An intelligent protective component consisting of a limit part, a reset part, and a drive component is used. This component locks the critical valve drive rod of the fire hydrant inside the protective shell. Only authorized personnel can unlock and open the protective cover by swiping a card to trigger the drive component (such as an electromagnet). This greatly enhances the operational safety of the fire hydrant, effectively prevents unauthorized misoperation and malicious theft, saves water, and ensures the availability of the equipment in emergencies.

[0007] Furthermore, the reset part includes a reset spring and a drive component connected to the limiting part, as well as a drive switch corresponding to the drive component; when the drive component receives a trigger signal, the drive component drives the limiting part away from the connecting buckle and compresses the reset spring.

[0008] Furthermore, the driving component is an electromagnet.

[0009] Furthermore, the electromagnet is electrically connected to the control module, and the control module controls its power supply.

[0010] Furthermore, the top of the protective shell is provided with a through hole, the top of the through hole is provided with an opening, and the limiting part is provided at the opening.

[0011] Furthermore, the top of the protective shell is connected to a connecting channel, which is adapted to the protective cover. When the protective cover is opened, the valve drive rod extends above the connecting channel.

[0012] Furthermore, the side wall of the equipment housing is connected with a clamp for fixing the equipment housing to the fire hydrant body.

[0013] Furthermore, the protective shell is detachably connected to the top of the fire hydrant body by bolts. Attached Figure Description

[0016] The following detailed description, in conjunction with the accompanying drawings, will further illustrate this utility model. Detailed Implementation

[0017] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. Several embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this utility model will be more thorough and complete.

[0018] It should be noted that when a component is said to be "fixed to" another component, it can be directly on the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0019] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0020] Please see Figures 1 to 3 The image shows a smart fire hydrant according to an embodiment of the present invention, which mainly includes a fire hydrant body 10, a protective component 20 detachably mounted on the valve drive rod 11 at the top of the fire hydrant body 10, and a monitoring device 30 detachably mounted on the fire hydrant body 10.

[0021] The fire hydrant body 10 is a conventional ground fire hydrant of the prior art, and its top is provided with a valve drive rod 11 for controlling the opening and closing of the valve.

[0022] The monitoring device 30 includes a device housing 31, a control module 32 disposed inside the device housing 31, and a water pressure sensor 33 electrically connected to the control module 32. Please see Figures 4 to 5 The protective component 20 includes a protective shell 21, a protective cover 22 hinged to the protective shell 21, a connecting buckle 23 provided on the protective cover 22, a limiting part 24 provided on the protective shell 21, and a reset part 25 for driving the limiting part 24 to move toward or away from the connecting buckle 23. The reset part 25 is used to lock or release the connecting buckle 23 by the limiting part 24.

[0023] It is worth noting that by setting up a monitoring device 30 connected to the water pressure sensor 33 and the control module 32, the internal water pressure of the fire hydrant can be continuously and in real time monitored. This effectively solves the drawbacks of the traditional manual inspection mode, such as long cycle, high cost, and inability to detect problems in a timely manner. Once an abnormal water pressure occurs (such as insufficient or excessive pressure), it provides a reliable water source for fire fighting and facilitates the timely detection of abnormal situations such as water leakage or theft by management personnel. An intelligent protective component 20, consisting of a limit part 24, a reset part 25, and a drive component 252, locks the critical valve drive rod 11 of the fire hydrant inside the protective shell 21. Only authorized personnel can unlock and open the protective cover 22 by swiping a card to trigger the drive component 252 (such as an electromagnet). This greatly enhances the operational safety of the fire hydrant, effectively prevents unauthorized personnel from misoperating or maliciously stealing the equipment, saves water, and ensures the availability of the equipment in emergency situations.

[0024] Furthermore, the reset part 25 includes a reset spring 251 connected to the limiting part 24 and a driving component, as well as a driving switch 253 corresponding to the driving component 252; when the driving component 252 receives a trigger signal, the driving component 252 drives the limiting part 24 away from the connecting buckle 23 and compresses the reset spring 251.

[0025] In this embodiment, the driving component 252 is an electromagnet. The electromagnet is electrically connected to the control module 32, and its power is controlled by the control module 32.

[0026] In this embodiment, the connecting buckle 23 is fixedly mounted on the inner wall of the protective cover 22. The protective shell 21 (connecting channel) has a through hole 261 at its top, and an opening 262 at the top of the through hole 261. A locking pin (limiting part 24) is located at the opening 262. The locking pin is horizontally positioned, and one end can be inserted into the locking hole of the connecting buckle 23. The return spring 251 is sleeved on the locking pin, with one end abutting against the inner wall of the connecting channel and the other end abutting against a protrusion on the locking pin, providing a constant thrust towards the connecting buckle 23 to keep it in the default locked position. In this embodiment, the driving component 252 is preferably an electromagnet, which is fixedly installed inside the connecting channel. The other end of the locking pin is made of ferromagnetic material and faces the driving end of the electromagnet.

[0027] Please see Figure 6 Furthermore, the monitoring device 30 also includes a wireless communication module 36 communicatively connected to the control module 32. The control module 32 (e.g., an MCU) is located inside the device housing 31 and is electrically connected to the water pressure sensor 33, the wireless communication module 36, the power module, and the positioning module 35 via cables. In this embodiment, the wireless communication module 36 is preferably an NB-IoT module, used to transmit water pressure data, device location, and status information to a remote monitoring center via the Internet of Things. The positioning module 35 is a GPS module used to obtain the precise geographical coordinates of the fire hydrant. The power module is a lithium battery that supplies power to all the aforementioned power-consuming modules. As a preferred alternative, the power module may also include a solar panel, connected via wires to replenish the lithium battery, enabling long-term maintenance-free operation.

[0028] In this embodiment, the detection end of the water pressure sensor 33 is connected to the side wall interface on the outlet side of the fire hydrant body 10 via a tee fitting. A rubber sealing ring is provided at this connection to ensure sealing and prevent leakage. The detection end of the water pressure sensor 33 thus extends into the internal water passage of the fire hydrant for real-time detection of internal water pressure.

[0029] Furthermore, a clamp 34 is connected to the side wall of the equipment housing 31 for fixing the equipment housing 31 to the fire hydrant body 10. The equipment housing 31 is made of engineering plastic and has good sealing and waterproof performance. The clamp 34 is a stainless steel metal clamp 34, which is tightly clamped to the neck of the fire hydrant body 10 by bolts, and firmly fixes the equipment housing 31 to it.

[0030] Specifically, the protective shell 21 is detachably connected to the top of the fire hydrant body 10 via bolts. The protective shell 21 is cylindrical, and its top has a connecting channel 26. The connecting channel 26 is adapted to the protective cover 22. When the protective cover 22 is open, the valve drive rod 11 extends above the connecting channel. The protective cover 22 is hinged to the top of the connecting channel 26 via a pivot. A torsion spring (not shown in the figure) is fitted on this pivot. One end of the torsion spring is fixed to the connecting channel 26, and the other end is fixed to the protective cover 22, so that the protective cover 22 has a tendency to automatically spring open when unlocked.

[0031] Working principle: Under normal monitoring conditions, the reset spring 251 pushes the locking pin, causing its end to insert into the locking hole of the connecting buckle 23, thus firmly locking the protective cover 22 and preventing it from being opened at will, effectively preventing theft and damage.

[0032] When authorized personnel need to perform fire-fighting operations or maintenance, the remote monitoring center can send an unlocking command to the control module 32 of the monitoring equipment 30, or the authorized personnel can swipe a card on the drive switch 253, and the control module 32 verifies the signal is valid. The control module 32 sends a trigger signal (briefly energized) to the electromagnet inside the protective component 20 via a cable. The electromagnet generates magnetic force, attracting the end of the locking pin made of ferromagnetic material, causing it to move backward against the elastic force of the return spring 251, thereby disengaging from the locking hole of the connecting buckle 23. Once the locking pin releases the connecting buckle 23, the protective cover 22 automatically pops open under the action of the torsion spring, allowing the operator to expose and operate the valve drive rod 11.

[0033] After the operation is completed, simply press down the protective cover 22 manually. The bottom guide surface of the connecting buckle 23 will contact the guide surface of the locking pin. Under pressure, the locking pin will be squeezed and temporarily downward. At this time, the return spring 251 will be squeezed. When the connecting buckle 23 moves away from the locking pin position, the return spring 251 will immediately push the locking pin to re-insert and lock, completing the closure.

[0034] In summary, the smart fire hydrant in the above embodiments of this utility model has the following beneficial effects: By setting up a monitoring device 30 connected to a water pressure sensor 33, a control module 32, and a wireless communication module 36, the internal water pressure of the fire hydrant can be continuously and in real time monitored, and the data can be remotely transmitted to the monitoring center. This effectively solves the drawbacks of the traditional manual inspection mode, such as long cycle, high cost, and inability to detect problems in a timely manner. Once an abnormal water pressure occurs (such as insufficient or excessive pressure), the system can immediately sound an alarm, providing a reliable water source guarantee for fire fighting and facilitating managers to promptly detect abnormalities such as leaks or theft.

[0035] The fire hydrant utilizes an intelligent protective element 20, comprised of a limiting part 24, a reset part 25, and a drive component 252. This protective element 20 locks the critical valve drive rod 11 within the protective housing 21, allowing only authorized personnel to unlock and open the protective cover 22 by remotely triggering the drive component 252 (e.g., an electromagnet). This significantly enhances the operational safety of the fire hydrant, effectively preventing unauthorized operation, protecting water supply, and ensuring equipment availability in emergencies.

[0036] The monitoring device 30 is securely fixed to the fire hydrant body 10 via a clamp 34 structure. Compared to adhesive or simple binding, this method offers stronger vibration and impact resistance, ensuring the stability and data reliability of the monitoring device 30 during long-term operation in harsh outdoor environments. Furthermore, the protective component 20 and the fire hydrant body 10, as well as the device housing 31 and the fire hydrant, utilize detachable connections (such as threads, clips, and clamps 34), making the installation, commissioning, and subsequent maintenance of the entire system very convenient and reducing the overall lifecycle maintenance cost. The detachable nature of the protective component 20 and the monitoring device 30 also allows for compatibility with various fire hydrants, eliminating the need to replace the original fire hydrant body 10 when intelligent control is required for ordinary fire hydrants.

[0037] The protective cover 22, with its hinge and torsion spring design, can automatically pop open after unlocking, allowing operators to quickly operate in emergency situations.
