Description

Technical Field

[0001] This utility model relates to the field of fire hydrants, and in particular to a device for testing water pressure sensors in intelligent fire hydrants. Background Technology

[0002] Smart fire hydrants are modern fire protection facilities based on Internet of Things (IoT) technology. They integrate sensors, communication modules, and data analysis systems to upgrade traditional fire hydrants to intelligent operation. Their core functions include real-time flow monitoring, water pressure sensing, leak warning, and remote status monitoring. They typically incorporate high-precision flow meters, pressure sensors, and positioning devices, and utilize low-power communication technologies such as NB-IoT and LoRa to transmit operational data to a cloud management platform in real time. Compared to traditional fire hydrants, smart fire hydrants can accurately record water consumption data, automatically identify abnormal water usage behavior (such as unauthorized opening or pipe bursts), and quickly locate fault points through visual maps, significantly improving the efficiency of fire protection network maintenance. This equipment has significant application value in smart city fire protection systems and industrial park security, effectively solving the "information silo" problem of traditional fire hydrants through data interconnection and providing a digital solution for fire water supply supervision.

[0003] Currently, manufacturers of intelligent fire hydrant equipment primarily use fire hydrant pressure testing machines to verify the proper functioning of the water pressure monitoring function. They compare the water pressure value reported by the intelligent hydrant with the reading on the mechanical pressure gauge installed on the testing machine to confirm the water pressure sensor's operation and the accuracy of the reported reading. However, this traditional testing method has several drawbacks: First, the accuracy is not ideal, relying on manual reading of the mechanical pressure gauge on the testing machine and comparison with the water pressure value reported by the intelligent hydrant, leaving room for improvement in accuracy. Second, the testing efficiency is low, as each intelligent fire hydrant must be installed on the testing machine one by one for pressure testing, making it impossible to test multiple intelligent fire hydrants simultaneously, resulting in low overall testing efficiency. Third, if a malfunction is detected in the water pressure sensor, it must be removed from the intelligent fire hydrant for subsequent equipment maintenance, which undoubtedly increases maintenance costs. Utility Model Content

[0004] Therefore, there is a need to provide a device for testing water pressure sensors in intelligent fire hydrants, which can solve the problems of insufficient accuracy, low efficiency, and high cost of existing testing methods.

[0005] To achieve the above objectives, this utility model provides a device for testing intelligent fire hydrant water pressure sensors, comprising a housing and a control module, a power conversion module, a booster pump, a water tank, and pipelines disposed inside the housing; a working panel is provided on the upper front side of the housing, the working panel having a button module, a water pressure preset module, multiple detection interfaces, and multiple pressure gauges connected to each detection interface; the control module is electrically connected to the booster pump, the button module, the power conversion module, and the water pressure preset module respectively; the pipelines are connected in series with the water tank and the booster pump; one end of the detection interface is used to connect to the water pressure sensor under test, and the other end is connected to the pipelines.

[0006] Furthermore, the water pressure preset module includes a low-pressure regulator, a medium-pressure regulator, and a high-pressure regulator.

[0007] Furthermore, the low-pressure regulator, medium-pressure regulator, and high-pressure regulator are all digital display gauges; or the pressure gauge is a digital display gauge.

[0008] Furthermore, a valve is provided between each of the detection interfaces and the pipeline.

[0009] Furthermore, the inlet of the booster pump is connected to the bottom of the water tank, the outlet is connected to one end of the pipeline, and the other end of the pipeline is connected to the top of the water tank.

[0010] Furthermore, the button module includes a power button, an emergency stop button, and high, medium, and low voltage knobs.

[0011] Furthermore, it also includes a warning light, which is mounted on the work panel and electrically connected to the control module.

[0012] Furthermore, it also includes a drain pipe, which is connected to the pipeline, and a drain valve is provided at the outlet end of the drain pipe.

[0013] Furthermore, it also includes an access door, which is located on the back of the housing.

[0014] Furthermore, a maintenance plate is provided on the upper part of the work panel, and the button module and the water pressure preset module are both located on the maintenance plate.

[0015] Unlike existing technologies, the above technical solution integrates functional modules such as a water pressure preset module, a booster pump, a power conversion module, a water tank, a control module, and pipelines to quickly set the water pressure and form a stable water flow in the pipelines inside the device. At the same time, by setting up multiple detection interfaces with one end connected to the pipeline and the other end used to connect to the water pressure sensor, multiple water pressure sensors are connected to the detection interfaces for synchronous detection, achieving high accuracy, high efficiency, and low cost pressure testing of the water pressure sensor.

[0032] Please see Figures 1 to 5This embodiment provides a device for testing intelligent fire hydrant water pressure sensors, including a housing 10 and a control module 20, a power conversion module 30, a booster pump 40, a water tank 50, and pipelines 60 disposed inside the housing 10. The housing 10 can be made of metal, such as iron, aluminum alloy, or stainless steel. The housing 10 can adopt a square box structure. A working panel 70 is provided on the upper front side of the housing 10. The working panel 70 is provided with a button module 71, a water pressure preset module 72, multiple detection interfaces 73, and multiple pressure gauges 74 connected to each detection interface 73. A platform can extend forward from the lower front side of the housing 10 for placing the water pressure sensor to be tested, facilitating the installation and testing of multiple water pressure sensors. The button module 71 includes a power button, an emergency stop button, and high, medium, and low pressure knobs. The power button is a push-button mechanical switch used to control the start or stop of the entire device. The emergency stop button is used to quickly stop the pressurization pump 40 in case of abnormal conditions during operation, preventing further damage. The high, medium, and low pressure knobs are used to switch the water pressure adjustment range, allowing for pre-adjustment of water pressure sensors with different pressure measurement ranges to the corresponding range, avoiding damage caused by accidentally setting a high water pressure that could impact a low water pressure sensor. The water pressure preset module 72 is used to set the water pressure in the pipeline 60. It is represented as a separate adjustment controller on the work panel 70, including a digital display and parameter adjustment buttons. By pressing the parameter adjustment buttons and observing the values ​​on the digital display, the preset water pressure parameters are set. After setting, this information is converted into an electrical signal and transmitted to the control module 20. The control module 20 controls the pressurization pump 40 to pressurize at the corresponding power, so that the water pressure in the pipeline 60 reaches the value set by the water pressure preset module 72. To facilitate quick adjustment to the required water pressure value, preferably, the water pressure preset module 72 includes a low-pressure regulator, a medium-pressure regulator, and a high-pressure regulator, corresponding to low, medium, and high water pressure ranges, respectively. For water pressure sensors used in different intelligent fire hydrants, the water pressure may vary, resulting in different measurement ranges for the sensors. By selecting the corresponding regulator for parameter setting based on the sensor's measurement range, the appropriate water pressure range can be quickly and easily determined, improving detection efficiency and effectively preventing damage to the sensor due to excessively high water pressure caused by misoperation. Furthermore, the low-pressure regulator, medium-pressure regulator, and high-pressure regulator are all digital display meters; or the pressure gauge 74 is a digital display meter, facilitating the reading and comparison of water pressure values ​​by testing personnel and improving efficiency.

[0033] The water tank 50 has a square or cylindrical structure. The inlet of the booster pump 40 is connected to the bottom of the water tank 50, and the outlet is connected to one end of the pipe 60. The other end of the pipe 60 is connected to the top of the water tank 50. This facilitates pressurized water circulation.

[0034] The button module 71 includes a power button, an emergency stop button, and high, medium, and low voltage knobs.

[0035] The water pressure preset module 72 can be implemented using a PCB circuit board in conjunction with mechanical touch electronic components, and can be found in existing technologies.

[0036] The booster pump 40 can be a centrifugal pump, reciprocating pump, vortex pump, or similar type. Their working principle is the same: applying additional pressure to the water flow through a mechanical device to drive circulation. Centrifugal pumps rely on a high-speed rotating impeller to generate centrifugal force, converting the kinetic energy of the water into pressure energy. Reciprocating pumps achieve pressurization by compressing the water chamber volume through the reciprocating motion of a piston or diaphragm. Vortex pumps utilize a special impeller to form a vortex flow channel, repeatedly accelerating the fluid to increase pressure.

[0037] The control module 20 is electrically connected to the pressurization pump 40, the button module 71, the power conversion module 30, and the water pressure preset module 72, respectively. The pipeline 60 is connected in series with the water tank 50 and the pressurization pump 40. One end of the detection interface 73 is connected to the water pressure sensor to be tested, and the other end is connected to the pipeline 60. In actual testing, since the number of water pressure sensors to be tested may not be exactly the same as the number of detection interfaces 73, when the number of water pressure sensors to be tested is less than the number of detection interfaces 73, in order to avoid water spraying out, the extra detection interfaces 73 can only be temporarily blocked. Alternatively, after one round of testing, the water in the pipeline 60 needs to be drained before all water pressure sensors can be removed, which is inconvenient. Preferably, each detection interface 73 is provided with a valve 75 between it and the pipeline 60. During testing, only the required number of valves 75 need to be opened. Furthermore, when replacing a water pressure sensor, only the valve 75 needs to be closed first to remove the corresponding water pressure sensor, thus improving work efficiency.

[0038] The control module 20 consists of a controller (such as a PLC or microcontroller), input / output modules, sensors, and actuators. The controller is the core component, responsible for receiving signals such as temperature, pressure, and position collected by the sensors, processing the data through a preset program, and then sending control commands to the actuators (such as motors or solenoid valves). The input / output modules realize signal conversion and transmission, and the power conversion module 30 provides power to ensure stable system operation. The communication interface supports data interaction between devices, ultimately achieving automated control of the equipment. The power conversion module 30 can consist of an input filter circuit, a rectifier (AC / DC converter), a power factor correction (PFC) circuit, a DC-DC converter, a voltage regulator circuit, and a protection module (such as overvoltage, overcurrent, and short-circuit protection). The input filter suppresses grid interference, the rectifier converts AC to DC, and the PFC optimizes energy utilization efficiency. The DC-DC converter adjusts the voltage level through high-frequency switching technology (such as Buck or Boost topology), and the voltage regulator circuit ensures stable output. The protection module monitors abnormalities in real time and cuts off power supply. Some modules integrate isolation transformers, EMI suppression components, and multiple output interfaces to meet the power requirements of the booster pump 40 and the low-voltage precision power consumption of the control module 20. They also have heat dissipation structures and communication functions to ensure long-term reliable operation of the system.

[0039] The detection interface 73 is used to connect to the sensing end of the water pressure sensor, such as a threaded interface.

[0040] It should be noted that valves can be installed at various nodes of the pipeline 60 and the water tank 50, and the number and location of valves can be adjusted according to the actual usage. For example, a valve can be installed at the outlet of the water tank 50, and a valve can be installed at the inlet of the booster pump 40, etc.

[0041] The working principle of this new device is as follows: the device is started by button module 71. According to the number of water pressure sensors to be tested, the valves connected to the corresponding number of detection interfaces 73 are opened. The water pressure sensors are assembled and connected to the detection interfaces 73, and the water pressure sensors are started to enter the working state. The water pressure preset module 72 is operated to adjust the water pressure to a certain value. The control module 20 receives the information from the water pressure preset module 72 and controls the pressurization pump 40 to start, drawing water from the water tank 50 into the pipeline 60. After the water pressure in the pipeline 60 stabilizes, the water pressure value of the water pressure sensor is observed and compared with the water pressure value of the water pressure preset module 72 to complete the pressure test of the water pressure sensor.

[0042] This novel intelligent fire hydrant water pressure sensor testing device integrates functional modules such as a water pressure preset module 72, a booster pump 40, a power conversion module 30, a water tank 50, a control module 20, and a pipeline 60. It enables rapid setting of water pressure and the formation of a stable water flow in the pipeline 60 within the device. Simultaneously, by setting multiple detection interfaces 73, one end of which connects to the pipeline 60 and the other end of which connects to the water pressure sensor, multiple water pressure sensors can be connected to the detection interfaces 73 for synchronous detection, achieving high accuracy, high efficiency, and low cost pressure testing of the water pressure sensor.

[0043] This novel intelligent fire hydrant water pressure sensor testing device integrates a water pressure preset module 72, which can display pipeline water pressure values ​​with high precision. While ensuring the accuracy of water pressure value readings, it also enables convenient data retrieval through digital display. Simultaneously, this novel intelligent fire hydrant water pressure sensor testing device is equipped with a multi-channel parallel pressure test interface 73, enabling simultaneous pressure testing of multiple water pressure sensors, greatly improving the testing efficiency of intelligent fire hydrant water pressure sensors. When conducting pressure tests on intelligent fire hydrant water pressure sensors using this novel intelligent fire hydrant water pressure sensor testing device, if any abnormality is detected in the water pressure sensor, timely maintenance and repair can be performed, which is convenient, quick, and cost-effective.

[0044] In some embodiments, a warning light 80 is also included, which is disposed on the work panel 70 and electrically connected to the control module 20. The warning light 80 is used to indicate the working status of the device to the operator, such as an off state when the light is off, a normal working state when the light is green, and an abnormal state when the light is red, so that the operator can receive the information in a timely manner and take corresponding actions to avoid damage to the device.

[0045] In some embodiments, a drain pipe 90 is also included, which is connected to the pipeline 60, and a drain valve 91 is provided at the outlet end of the drain pipe 90. After the inspection is completed or when maintenance is required, the water in the pipeline 60 can be drained through the drain pipe 90 to facilitate maintenance and other operations.

[0046] In some embodiments, an access door 92 is also included, which is located on the back of the housing 10. This facilitates personnel access to the interior of the housing 10 for maintenance or repair.

[0047] In some embodiments, a maintenance plate 93 is provided on the upper part of the work panel 70, and the button module 71 and the water pressure preset module 72 are both located on the maintenance plate 93. This allows staff to directly open the maintenance plate 93 to repair and maintain some electronic components inside the housing 10.

[0048] It should be noted that, to avoid unclear attached images, [the following text is missing]. Figure 1-5The electrical wires are not shown in the diagram. The control module, power conversion module, pressurization pump button module, and water pressure preset module can all be electrically connected by electrical wires.

[0049] It should be noted that although the above embodiments have been described herein, this does not limit the scope of patent protection for this utility model. Therefore, any changes and modifications made to the embodiments described herein based on the innovative concept of this utility model, or equivalent structural or procedural transformations made using the content of this utility model's specification and drawings, directly or indirectly applying the above technical solutions to other related technical fields, are all included within the scope of protection of this utility model patent.
