Description

Technical Field

[0001] This application relates to the technical field of fire hydrant detection, and in particular to a fire hydrant water level and pressure detection device. Background Technology

[0002] As a key facility in the urban fire emergency system, the sufficiency of water level and the stability of pressure of fire hydrants directly determine the success or failure of fire fighting. If the water level of fire hydrants is insufficient or the pressure is unstable, the fire fighting efficiency will be reduced, and the fire may even spread and cause additional casualties and property losses.

[0003] Currently, the water level and pressure testing of fire hydrants still relies mainly on regular manual on-site inspections. This involves fire departments sending personnel with tools such as pressure gauges and water level gauges to inspect each fire hydrant in their jurisdiction on a quarterly or semi-annual basis. This method has become severely limited given the surge in the number of fire hydrants in cities. Manual testing requires personnel to be on-site and manually connect the testing equipment and record the data. Although there are a few fire hydrant testing devices on the market, most are designed for single-parameter monitoring and cannot simultaneously obtain both water level and pressure, resulting in insufficient data completeness and an inability to comprehensively assess the emergency water supply capacity of fire hydrants.

[0004] Regarding the aforementioned technologies, the inventors discovered that traditional manual inspection requires a significant investment of manpower, as well as the availability of inspection tools and vehicles. Furthermore, manually recorded data must be manually entered into the system, which is prone to errors and omissions. Regular manual inspections cannot achieve real-time monitoring, and sudden problems such as water level drops and pressure changes in fire hydrants can only be discovered during the next inspection, resulting in a long response time. Single pressure monitoring cannot determine the water level status and carries the risk of misjudging that the pressure is normal but there is no water. Utility Model Content

[0005] To overcome the challenges of existing manual inspection methods that require significant manpower, inspection tools, and vehicles, as well as the fact that manually recorded data is prone to errors and omissions, and that manual periodic inspections cannot achieve real-time monitoring, sudden problems such as water level drops and pressure changes in fire hydrants can only be detected during the next inspection due to long response times, and that single pressure monitoring cannot determine the water level status and may result in the risk of misjudging that the pressure is normal but there is no water, this application provides a fire hydrant water level and pressure detection device.

[0006] The fire hydrant water level and pressure detection device provided in this application adopts the following technical solution: A fire hydrant water level and pressure detection device includes a fire hydrant body and a detection component. A spiral tube is vertically connected and fixed to the top of the fire hydrant body's pipe. A detection component is vertically installed on the spiral tube of the fire hydrant body. The detection component includes a water level detection cylinder, a pressure detection cylinder, a processor module, a position sensor, and a lifting component. A pressure detection cylinder is vertically connected and assembled to the top of the water level detection cylinder, and the bottom of the water level detection cylinder is connected and assembled to the spiral tube of the fire hydrant body. Multiple movable electrical contact rings are vertically embedded and fixed on the inner circumference of the water level detection cylinder and the pressure detection cylinder. Electrical sockets are fixed through the outer wall of the multiple movable electrical contact rings, and a position sensor is electrically connected to the electrical sockets. A processor module is fixed to the upper end of the outer wall of the water level detection cylinder, and the processor module is electrically connected and assembled with the position sensor. A lifting component is vertically installed in both the water level detection cylinder and the pressure detection cylinder, and a floating platform is provided at the bottom of the lifting component, with the floating platform inserted into the pipe of the fire hydrant body.

[0007] By adopting the above technical solution, the fire hydrant water level and pressure detection device achieves real-time monitoring of the water level and pressure inside the fire hydrant through the fire hydrant body and detection components. The spiral tube of the fire hydrant body provides a channel for the introduction of water into the fire hydrant, while the water level detection cylinder and pressure detection cylinder in the detection components are used to detect changes in water level and pressure, respectively. A position sensor embedded in a movable contact ring monitors the position change of the floating platform, and then transmits the signal to the processor module through the power socket to display the water level and pressure data in real time. The floating platform in the lifting component floats on the water surface and can be controlled to rise and fall with changes in water level, improving detection accuracy. The processor module receives signals from the position sensor, processes and analyzes the data, and finally outputs the detection results. When the water level or pressure inside the fire hydrant changes, the floating platform moves up and down accordingly. The connected movable contact ring and position sensor convert the position information into electrical signals, which are transmitted to the processor module for analysis and processing. The processor module displays or records the detection results to ensure that the fire hydrant is in good working condition.

[0008] Optionally, the bottom of the water level detection cylinder is vertically connected to and fixed with a lower assembly cylinder seat, and the lower assembly cylinder seat is threadedly connected to and assembled in the threaded tube of the fire hydrant body, while the top of the water level detection cylinder is vertically connected to and fixed with an upper assembly screw ring.

[0009] By adopting the above technical solution, the bottom end of the water level detection cylinder is fixed to the lower assembly cylinder seat via a threaded connection. The lower assembly cylinder seat is then fixed to the threaded tube of the fire hydrant body via a threaded connection, thus serving the function of detecting the water level. The upper assembly ring is fixedly connected to the top end of the water level detection cylinder for connection with the pressure detection cylinder.

[0010] Optionally, the bottom end of the pressure detection cylinder is provided with a screw groove, and the screw groove is threadedly connected to the upper assembly screw ring on the water level detection cylinder.

[0011] By adopting the above technical solution, a threaded groove is provided at the bottom of the pressure detection cylinder, which is threadedly connected to the upper assembly threaded ring on the water level detection cylinder to form an integral structure. This system monitors the water level in the fire hydrant through the water level detection cylinder to ensure sufficient fire-fighting water supply; the pressure detection cylinder monitors the pressure of the fire-fighting water to ensure that the fire-fighting system can provide sufficient pressure in emergencies for stable and reliable fire-fighting water spraying. This dual monitoring of water level and pressure ensures the overall performance and reliability of the fire-fighting system and improves the efficiency of emergency fire response.

[0012] Optionally, the lifting component includes a lower lifting block and an upper lifting block, which are vertically slidably inserted into the water level detection cylinder and the pressure detection cylinder, respectively. A pressure-retaining electrical ring is embedded and fixed on the outer wall of both the lower and upper lifting blocks. A spiral-shaped electrical wire is connected and fixed on the pressure-retaining electrical ring, and the electrical wire on the pressure-retaining electrical ring passes through the water level detection cylinder or the pressure detection cylinder and is electrically connected to an external power supply line.

[0013] By adopting the above technical solution, the lifting component consists of a lower lifting block and an upper lifting block, which can be vertically slidably installed in the water level detection cylinder and the pressure detection cylinder, respectively. This design allows for flexible detection of water level and pressure. A pressure-bearing electrical contact ring is embedded and fixed in the outer wall of both the lower and upper lifting blocks. This pressure-bearing electrical contact ring is electrically connected to an external power supply line via a spiral-shaped electrical contact wire, thereby enabling accurate acquisition of detection data at different locations.

[0014] Optionally, brackets are vertically fixed on the adjacent end faces of the lower lifting block and the upper lifting block, and assembly blocks and assembly frames are vertically fixed on the adjacent ends of the brackets of the lower lifting block and the upper lifting block, respectively.

[0015] By adopting the above technical solution, brackets are vertically fixed on the end faces of adjacent lower and upper lifting blocks, with an assembly insert fixed on one bracket and an assembly frame fixed on the other. This design allows the lifting components to be stably assembled and fixed under different water levels and pressure environments, ensuring the stability and reliability of the entire detection system. When the lifting components move within the water level and pressure detection cylinders, the pressure-resistant contact ring will contact or separate from the detection circuit fixed inside the cylinder at the corresponding position. The electrical signal is transmitted to the external signal acquisition device through the contact wire. At the same time, the assembly structure of the lifting components ensures their fixation and stability in different positions, thereby achieving accurate detection of water level and pressure.

[0016] Optionally, the assembly blocks and assembly frames at adjacent ends of the lower and upper lifting blocks are slidably inserted, and the assembly blocks and assembly frames are fixedly assembled by locking screws.

[0017] By adopting the above technical solution, the lower lifting block and the upper lifting block are connected by the sliding insertion of the assembly blocks and assembly frames at adjacent ends, and then fixed by locking screws to ensure a stable connection. They can be disassembled and reassembled when needed, which improves the modularity and installation flexibility.

[0018] Optionally, a screw is vertically fixed on the bottom surface of the lower lifting block, and a screw cylinder is assembled on the screw with vertical threads, and a floating platform is vertically fixed at the bottom end of the screw cylinder.

[0019] By adopting the above technical solution, a screw is vertically fixed to the bottom surface of the lower lifting block, and a screw cylinder is assembled with vertical threads on the screw. A floating platform is vertically fixed to the bottom end of the screw cylinder. During operation, by controlling the rotation of the screw within the screw cylinder, the lower lifting block can be raised and lowered vertically, thereby driving the upper lifting block and the entire mechanism to rise and fall, achieving height adjustment. The floating platform provides support during the lifting process, ensuring smooth lifting, reducing vibration and swaying, and improving the working stability of the mechanism.

[0020] Optionally, both ends of the position sensor are electrically connected to electrical connection wires, and both ends of the processor module are fixed with electrical connection sockets. The electrical connection wire at one end of the position sensor is electrically inserted into the electrical connection socket, and the electrical connection wire at the other end of the position sensor is electrically connected to the power socket.

[0021] By adopting the above technical solution, the position sensor is used to detect information at a specific location and transmits the detected data to the processor module and other circuits via electrical connection lines at both ends. The processor module receives the position information from the position sensor through electrical connection sockets at its upper and lower ends. One end of the position sensor is plugged into the processor module's electrical connection socket via an electrical connection line to ensure the reliability and accuracy of data transmission; the other end of the electrical connection line is directly connected to a power socket, enabling the position information to be transmitted to other control parts or actuators of the system, thereby achieving precise position monitoring and automatic response. The position information detected by the position sensor is transmitted to the processor module via electrical connection lines. After receiving and processing this information, the processor module transmits the processing results to other parts via electrical connection lines, realizing precise monitoring and automated control of equipment position.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. By using a water level and pressure linkage detection structure, two key indicators can be acquired simultaneously, completely solving the problem of data fragmentation. Water level and pressure data are collected synchronously. During detection, the rise and fall of the water level in the fire hydrant's main pipe causes the floating platform to float, which in turn pushes the lower and upper lifting blocks to rise and fall vertically synchronously within the water level and pressure detection cylinders. Water level data is obtained by the lifting blocks pressing against the moving contact rings at different heights, accurately identifying whether the water level has reached the supply threshold. Pressure data is obtained through the buoyancy changes caused by the rise and fall of the water level, simultaneously determining whether the pressure meets fire extinguishing requirements. Compared to single pressure monitoring, which has a high false alarm rate, and single water level monitoring, which cannot assess pressure, this fully meets the data reliability requirements for emergency decision-making. Position sensors on the inner walls of the water level and pressure detection cylinders transmit the lifting block position signals to the processor module in real time. The processor module quickly processes the data using a water level and pressure correlation algorithm, improving data accuracy compared to manual recording, with smaller water level and pressure errors, providing precise data support for fire hydrant maintenance. 2. Through automatic lifting detection and real-time signal transmission, the system achieves uninterrupted monitoring of fire hydrant status around the clock, completely eliminating emergency blind spots. The system is continuously powered by an external power supply line via a connecting wire. The floating platform floats in real time with changes in water level and pressure. The contact state of the lifting block's pressure contact ring and the moving contact ring changes synchronously. The position sensor transmits abnormal signals to the processor module in real time. The processor module pushes alarm signals to the terminal display through an integrated signal transmitter. This technology reduces the response time to sudden problems such as pipeline leaks and valve failures, saving time for emergency repairs. Attached Figure Description

Multiple movable electrical contact rings 25 are vertically embedded and fixed on the inner circumferential surfaces of the water level detection cylinder 21 and the pressure detection cylinder 22. A power socket 251 is fixed through the outer wall of the water level detection cylinder 21 or the pressure detection cylinder 22 on each of the multiple movable electrical contact rings 25.

[0027] By adopting the above technical solution, the fire hydrant water level and pressure detection device realizes real-time monitoring of the water level and pressure inside the fire hydrant through the fire hydrant body 1 and the detection component 2. The screw tube 11 of the fire hydrant body 1 provides a channel for the introduction of water into the fire hydrant, while the water level detection cylinder 21 and pressure detection cylinder 22 in the detection component 2 are used to detect changes in water level and pressure, respectively. A position sensor 24 is embedded in a movable power contact ring 25 to monitor the position change of the float 29, and then transmits the signal to the ESP32-WROOM-32 processor module 23 via a power contact socket, displaying the water level and pressure data in real time. The float 29 in the lifting component floats on the water surface and can be controlled to rise and fall with changes in water level, improving detection accuracy. The processor module 23 receives the signal from the position sensor 24, processes and analyzes the data, and finally outputs the detection results. When the water level or pressure in the fire hydrant changes, the floating platform 29 moves up and down accordingly. The connected movable contact ring 25 and position sensor 24 convert the position information into electrical signals, which are transmitted to the processor module 23 for analysis and processing. The processor module 23 displays or records the detection results to ensure that the fire hydrant is in good working condition.

[0028] Reference Figure 3 and Figure 4 The bottom end of the water level detection cylinder 21 is vertically connected to and fixed with a lower assembly cylinder seat 211, which is threadedly connected to the threaded tube 11 of the fire hydrant body 1. The top end of the water level detection cylinder 21 is vertically connected to and fixed with an upper assembly screw ring 212. The bottom end of the water level detection cylinder 21 is threadedly connected to the lower assembly cylinder seat 211, which is then threadedly fixed to the threaded tube 11 of the fire hydrant body 1, thus serving to detect the water level. The upper assembly screw ring 212 is fixedly connected to the top end of the water level detection cylinder 21 for connection with the pressure detection cylinder 22. The bottom end of the pressure detection cylinder 22 has a screw groove 221, which is threadedly connected to the upper assembly screw ring 212 on the water level detection cylinder 21. The bottom end of the pressure detection cylinder 22 has a screw groove 221, which is threadedly connected to the upper assembly screw ring 212 on the water level detection cylinder 21, forming an integral structure. The system monitors the water level in the fire hydrants through the water level detection cylinder 21 to ensure sufficient fire-fighting water supply; the pressure detection cylinder 22 monitors the pressure of the fire-fighting water to ensure that the fire-fighting system can provide sufficient pressure in emergencies to stably and reliably spray fire-fighting water. This dual monitoring of water level and pressure ensures the overall performance and reliability of the fire-fighting system and improves the efficiency of emergency fire response.

[0029] Reference Figure 4 and Figure 5The lifting component 26 includes a lower lifting block 261 and an upper lifting block 262, which are vertically slidably inserted into the water level detection cylinder 21 and the pressure detection cylinder 22, respectively. A pressure-bearing electrical contact ring 263 is embedded and fixed on the outer wall of both the lower and upper lifting blocks 261 and 262. A spiral-shaped electrical contact wire 264 is connected and fixed to the pressure-bearing electrical contact ring 263, and the electrical contact wire 264 on the pressure-bearing electrical contact ring 263 passes through the water level detection cylinder 21 or the pressure detection cylinder 22 and is electrically connected to an external power supply line. The lifting component 26, composed of the lower lifting block 261 and the upper lifting block 262, can be vertically slidably installed in the water level detection cylinder 21 and the pressure detection cylinder 22, respectively. This design allows for flexible detection of water level and pressure. The outer walls of the lower lifting block 261 and the upper lifting block 262 are embedded with pressure-bearing electrical rings 263, which are electrically connected to an external power supply line via spiral-shaped electrical wires 264, thereby enabling accurate acquisition of detection data at different locations. Supports 265 are vertically fixed to adjacent end faces of both the lower lifting block 261 and the upper lifting block 262, and assembly blocks 266 and assembly frames 267 are vertically fixed to adjacent ends of the supports 265 of both the lower and upper lifting blocks 261 and 262, respectively. This design allows the lifting components to be stably assembled and fixed under different water levels and pressure environments, ensuring the stability and reliability of the entire detection system. When the lifting component moves within the water level detection cylinder 21 and the pressure detection cylinder 22, the pressure contact ring 263 will contact or separate from the detection circuit fixed inside the cylinder at the corresponding position. The electrical signal is transmitted to the external signal acquisition device through the contact wire 264. At the same time, the assembly structure of the lifting component ensures its fixation and stability at different positions, thereby achieving accurate detection of water level and pressure.

A screw rod 27 is vertically fixed to the bottom surface of the lower lifting block 261, and a screw cylinder 28 is vertically threaded onto the screw rod 27. A floating platform 29 is vertically fixed to the bottom end of the screw cylinder 28. The lower lifting block 261 and the upper lifting block 262 are connected by sliding insertion of the assembly blocks 266 and assembly frames 267 at their adjacent ends, and are then fixed together by locking screws 268. During operation, by controlling the rotation of the screw 27 within the screw barrel 28, the lower lifting block 261 can be raised and lowered vertically, thereby driving the upper lifting block 262 and the entire mechanism to rise and fall, achieving height adjustment. The floating platform 29 provides support during the lifting process, ensuring smooth lifting, reducing vibration and swaying, and improving the working stability of the mechanism.

[0031] Reference Figure 3 and Figure 4 The position sensor 24 has electrical connection wires 241 at both ends, and the processor module 23 has electrical connection sockets 231 fixed at both ends. One end of the position sensor 24's electrical connection wire 241 is electrically inserted into the electrical connection socket 231, and the other end of the position sensor 24's electrical connection wire 241 is electrically connected to the power socket 251. The position sensor 24 is used to detect information at a specific location and transmits the detected data to the processor module 23 and other circuits via its two electrical connection wires 241. The processor module 23 receives the position information from the position sensor 24 through its two electrical connection sockets 231. One end of the position sensor 24 is connected to the processor module 23's electrical connection socket 231 via the electrical connection wire 241 to ensure the reliability and accuracy of data transmission; the other end of the electrical connection wire 241 is directly connected to the power socket 251, enabling the position information to be transmitted to other control parts or actuators of the system, thereby achieving precise position monitoring and automatic response. The position information detected by the position sensor 24 is transmitted to the processor module 23 via the electrical connection line 241. After receiving and processing this information, the processor module 23 transmits the processing results to other parts via the electrical connection line 241, thereby realizing accurate monitoring and automated control of the equipment position.

[0032] The implementation principle of a fire hydrant water level and pressure detection device according to an embodiment of this application is as follows: First, based on the pipe length of the fire hydrant body 1, the screw cylinder 28 is rotated and slides vertically down the screw 27 to extend, thereby controlling the insertion depth of the floating platform 29 into the pipe of the fire hydrant body 1. Then, the lower lifting block 261 and the upper lifting block 262 in the lifting component 26 are slidably inserted into the water level detection cylinder 21 and the pressure detection cylinder 22, respectively. At the same time, the screw ring 212 and the screw groove 221 are threadedly connected and assembled on the adjacent ends of the water level detection cylinder 21 and the pressure detection cylinder 22 in the detection component 2. Then, the lower assembly cylinder seat 211 at the bottom of the water level detection cylinder 21 is threadedly assembled into the screw tube 11 at the top of the pipe of the fire hydrant body 1, thus completing the assembly of the detection component 2 and the fire hydrant body 1. Then, the connecting wires 264 connected to the pressing contact rings 263 of the lower lifting block 261 and the upper lifting block 262 are respectively passed through the water level detection cylinder 21 and the pressure detection cylinder 22 and electrically connected to the external power supply line. At the same time, the adjacent end brackets 265 of the lower lifting block 261 and the upper lifting block 262 are fixed by the assembly plug 266 and the assembly frame 267 and the locking screws 268. The power sockets 251 on the multiple movable contact rings 25 embedded in the inner wall of the water level detection cylinder 21 and the pressure detection cylinder 22 are electrically connected to the electrical connection line 241 at one end of the position sensor 24. The electrical connection line 241 at the other end of the position sensor 24 is electrically connected to the processor module 23. Finally, during testing, the water level in the pipe of the fire hydrant body 1 rises and falls due to the internal water pressure. The floating support causes the floating platform 29 to rise in the pipe of the fire hydrant body 1, pushing the lower lifting block 261 and the upper lifting block 262 to rise and fall vertically in the water level detection cylinder 21 and the pressure detection cylinder 22. The lower lifting block 261 and the upper lifting block 262 press against the electric contact ring 263 and the moving electric contact ring 25 at different height positions, thereby connecting the position sensors 24 at different heights of the water level detection cylinder 21 and the pressure detection cylinder 22 to transmit electrical signals to the processor module 23. Based on the electrical signals received by the position sensors 24 at different heights of the water level detection cylinder 21 and the pressure detection cylinder 22 in the processor module 23, the integrated signal transmitter transmits the water level signal and pressure signal in the pipe of the fire hydrant body 1 to the terminal for display.
