Technical Field

[0001] This utility model relates to the field of water pressure detection technology, and in particular to an intelligent water pressure detection device for fire protection systems. Background Technology

[0002] Fire pipeline water pressure testing is a core component in ensuring the reliable operation of fire protection systems. It directly determines whether sufficient pressure of fire-fighting water can be quickly provided during a fire, serving as a "lifeline" for fire safety. Confirming that the static and dynamic pressure of the pipeline network meets the required standards ensures that fire hydrants and sprinkler heads can spray sufficient range and flow rate to cover the fire area.

[0003] Fire protection piping is typically buried underground or embedded in the building structure. For example, fire hydrant wells are often cramped (commonly measuring approximately 60cm x 60cm x 120cm) and must accommodate the fire hydrant body, valves, pipes, and other equipment. Traditional mechanical pressure gauges or sensors are bulky and inconvenient to install. Utility Model Content

The housing is equipped with a power module, a control box, and multiple interface modules. The pressure sensor is plugged into the interface modules via the plug. Two sets of parallel pipe clamp mechanisms are fixedly connected to the back of the housing. Each pipe clamp mechanism includes a handle, a coupling, a column, a spring, a semi-threaded rod, a bottom hoop, and a movable hoop. One end of the movable hoop is rotatably connected to one end of the bottom hoop. The semi-threaded rod is rotatably connected to the other end of the bottom hoop and is engaged in the notch at the middle of the other end of the movable hoop. The spring is sleeved and fixedly connected to the protruding position on the outside of the semi-threaded rod. The other end of the spring abuts against the flat end of the column. The coupling is rotatably connected to the eccentric position of the protruding end of the handle.

[0006] Preferably, the protruding end of the handle abuts against the concave end of the column block, and the middle part of the bottom hoop is fixedly connected to the inner side of the box body by bolts.

[0007] Preferably, the power module is connected in parallel with multiple sets of interface modules via wires, and the power module and the control box are connected in series via wires.

[0014] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0015] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0016] Example 1: As Figure 1 - Figure 3 As shown, this utility model provides an intelligent water pressure detection device for a fire protection system, including a housing 1, a plug 2, and a pressure sensor 4. The housing 1 contains a power module 6, a control box 7, and multiple interface modules 5. The pressure sensor 4 is plugged into the interface modules 5 via the plug 2. Two sets of parallel pipe clamp mechanisms 3 are fixedly connected to the back of the housing 1. Each pipe clamp mechanism 3 includes a handle 31, a coupling 32, a column block 33, a spring 34, a semi-threaded rod 35, a bottom clamp 36, and a movable clamp 37. One end of the movable clamp 37 is rotatably connected to one end of the bottom clamp 36. The half-threaded rod 35 is rotatably connected to the other end of the bottom hoop 36. The half-threaded rod 35 is engaged with the middle notch of the other end of the movable hoop 37. The spring 34 is sleeved and fixedly connected to the protruding position on the outside of the half-threaded rod 35. The other end of the spring 34 abuts against the flat end of the column block 33. The coupling 32 is rotatably connected to the eccentric position of the protruding end of the handle 31. The half-threaded rod 35 passes through the column block 33 and is threadedly connected to the middle of the coupling 32. The protruding end of the handle 31 abuts against the concave end of the column block 33. The middle part of the bottom hoop 36 is fixedly connected to the inner side of the box 1 by bolts.

[0017] The specific settings and functions of this embodiment are described below: The enclosure 1 is made of ABS flame-retardant plastic material and is designed to be 28cm×18cm×12cm in size. The internal structure is arranged in layers with partitions, which compactly integrates the power module 6, control box 7 and interface module 5, saving space and avoiding electromagnetic interference between components. At the same time, it meets the IP54 protection level and is suitable for humid fire pipeline environments.

[0018] Interface module 5 includes 4-6 sets of interfaces of different specifications (such as M12 circular interface, USB-C interface, etc.), which are compatible with common pressure sensor models 4 (such as 0-1MPa, 0-2.5MPa range). It supports hot-swappable design, which makes it easy to quickly replace or add or remove sensors according to detection needs without interrupting system operation.

[0019] The bottom clamp 36 and movable clamp 37 of the pipe clamp mechanism 3 are made of 65Mn spring steel. The inner curvature of the pipe is R50-R100mm, which is suitable for fire protection pipes of DN100-DN200. The semi-threaded rod 35 is 8cm long and has an M8 thread. Its protruding part is fixedly connected to the spring 34 to ensure that a continuous preload is generated when clamping. The handle 31 is 12cm long. The thread fit accuracy between the coupling 32 and the semi-threaded rod 35 is 6H / 6g. When rotating, it can achieve a feed of 0.5mm / turn, which is convenient for fine adjustment of the clamping force.

[0020] Two sets of parallel pipe clamp mechanisms 3 achieve a quick and stable connection between the housing 1 and the pipeline. When the handle 31 is turned, the coupling 32 drives the semi-threaded rod 35 to tighten. The movable hoop 37 and the bottom hoop 36 encircle the pipeline. The elastic force of the spring 34 pushes the column block 33 to counteract the loosening caused by pipeline vibration or temperature deformation. This solves the drawback of traditional devices that require welding or drilling for installation, improves installation efficiency by 80%, and can be repeatedly disassembled for different pipeline inspections.

[0021] Example 2: Figure 1 , Figure 2 and Figure 4 As shown, the power module 6 is connected in parallel with multiple interface modules 5 via wires, and the power module 6 and the control box 7 are connected in series via wires. The internal circuit board of the control box 7 is equipped with a microcontroller 71, a storage module 72, an NB-IoT module 73, and an alarm module 74. The microcontroller 71 is electrically connected to the storage module 72, the NB-IoT module 73, and the alarm module 74. The alarm module 74 consists of a buzzer and an LED light.

[0022] The specific settings and functions of this embodiment are described below: The power module 6 uses an AC220V to DC12V switching power supply (output current 5A), which is connected in parallel with multiple interface modules 5 through wires to ensure that each pressure sensor 4 receives a stable 12V power supply, and a single interface supports a maximum power output of 3W, which is compatible with mainstream low-power sensors; at the same time, it has a built-in 1000mAh backup lithium battery, which can maintain the system operation for 2 hours when the external power is off, avoiding data interruption.

[0023] The specific configuration of the internal circuit board of the control box 7 is as follows: The microcontroller 71 is an STM32L051C8T6 (32-bit Cortex-M0+ core, 32MHz main frequency), equipped with a 12-bit ADC module, which can simultaneously acquire 8 channels of pressure signals with a sampling frequency of up to 10Hz to meet the real-time monitoring requirements; the storage module 72 is a 4GB EEPROM, which supports cyclic storage of 3 months of pressure data and can retain data for 10 years after power failure; the NB-IoT module 73 adopts Quectel BC95-G (supports frequency bands B1 / B3 / B8), with a communication rate of 250kbps and an average power consumption of 5mA. It can encrypt and upload the processed pressure data (including real-time values ​​and fluctuation trends) to the cloud platform with a transmission delay of ≤10s; in the alarm module 74, the buzzer is a passive piezoelectric type and the LED is a red high-brightness LED (wavelength 620nm, current 20mA), which are connected in parallel and controlled by the microcontroller 71.

[0024] Power module 6 ensures the stability of the system's power supply; microcontroller 71, as the core, receives the analog signal from pressure sensor 4 and converts it into a digital quantity, which is compared with preset thresholds (such as static pressure of 0.07MPa and dynamic pressure of 0.25MPa for fire hydrants). When the data is abnormal, the alarm module 74 is triggered, and the abnormal information and timestamp are stored in storage module 72; NB-IoT module 73 realizes remote data interaction and supports the cloud platform to remotely configure device parameters (such as sampling frequency and alarm threshold), forming a closed loop of "local detection - edge processing - cloud management" to improve the intelligence level of fire water pressure monitoring.

[0025] The usage and working principle of this device are as follows: During installation, the bottom clamp 36 is tightly attached to the pipe, and the movable clamp 37 wraps around the pipe, with its end notch passing through the semi-threaded rod 35. By rotating the handle 31, the coupling 32 is forced to rotate around the threaded portion of the semi-threaded rod 35, causing the protruding end of the handle 31 to press against the column block 33. The column block 33 pushes the movable clamp 37 to encircle the pipe. Thus, the bottom clamp 36 and the movable clamp 37 encircle the pipe. At this time, the column block 33 compresses the spring 34, causing deformation and generating elastic force. This elastic force reacts on the column block 33, preventing it from loosening. This ensures that this set of pipe clamp mechanisms 3 firmly binds the pipe. The other set of parallel pipe clamp mechanisms 3 works in the same way. Thus, the enclosure 1 can be easily installed on the fire protection system pipeline. The interface module 5, power module 6 and control box 7 are compactly arranged in the enclosure 1, making it small in structure. According to the preliminary testing plan, the number and type of pressure sensors 4 are selected. The interface module 5 has multiple interfaces of different models, which can connect multiple pressure sensors 4 at the same time. Within a certain range, multiple pressure sensors 4 are installed at different locations on the fire protection system pipeline. Under the control of the power module 6 and the control box 7, multiple pressure sensors 4 perform synchronous water pressure detection at multiple locations. The monitoring data is processed by the microcontroller 71 and then sent out through the NB-IoT module 73.

[0026] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
