[0002] Currently, traditional DMA metering devices and related facilities mainly suffer from the following technical defects: First, the facilities have low integration and operate in harsh environments. Existing flow meters, pressure sensors, water quality monitors, etc., are mostly installed in scattered locations, with the carriers often being brick or cement-cast valve wells. These wells have long construction cycles, poor sealing, and are easily infiltrated by groundwater, surface water, and impurities, leading to valve corrosion, equipment dampness, and water and gas accumulation inside the wells, affecting the stable operation of the equipment and posing safety hazards.

[0003] Second, leakage detection methods are limited and inefficient. Existing leakage detection methods mostly rely on manual inspection and listening or portable correlators, which have long detection cycles and depend on experience for location, making it difficult to achieve routine monitoring. Some fixed noise monitoring equipment has problems such as limited detection distance and high false alarm rate, and lacks intelligent leakage point location capabilities.

[0004] Third, data acquisition and remote transmission capabilities are insufficient. Data from various sensors is scattered, lacking a unified data acquisition and remote transmission platform.

Detailed Implementation

[0022] This invention provides a DMA metering device with leak detection function, such as... Figure 1-5 As shown, the device includes a well body 101, within which a component cavity 120 is provided. A water inlet pipe 102 is installed at one end of the component cavity 120, and a water outlet pipe 111 is installed at the other end. Pipe rubber rings 106 are provided at the connection points between the water inlet pipe 102 and the water outlet pipe 111 and the inner wall of the component cavity 120. A water inlet valve 118 is installed and connected to one end of the water inlet pipe 102, and the water inlet pipe 102 and the water inlet valve 118 are connected by a flange. An adjustable telescopic pipe 117 is connected to the flange at the other end of the water inlet valve 118. A metering pipe 115 is connected to the flange at one end of the telescopic pipe 117. A metering support rod 114 is fixedly installed on the top of the outer end face of the metering pipe 115, and a meter 116 is installed on the top of the metering support rod 114. The detection contact of the meter 116 extends downward into the interior of the metering pipe 115.

[0023] Furthermore, a water quality detector 125 is installed at the upper end of the water outlet pipe 111 and inside the component cavity 120, and a pressure sensor 126 is installed on the other side of the water quality detector 125.

[0024] It should be further explained that the meter 116 is used to collect flow data in real time, and combined with the information from multiple parameters such as the pressure sensor 126 and the water quality analyzer 125, it is uploaded to the management platform through remote communication to realize remote monitoring, anomaly warning and intelligent scheduling, and provide data support for DMA zone metering construction and pipeline leakage control.

[0025] Furthermore, a water quality monitoring pipe 109 is connected to one end of the metering pipe 115 via a flange, and a water quality safety protection valve 113 is installed on the top of the water quality monitoring pipe 109.

[0026] It is worth further explaining that the water quality safety protection valve 113 works in conjunction with the water quality detector 125. When the water quality parameters are abnormal, it can automatically cut off the water source to prevent the polluted water from entering the downstream pipe network.

[0027] Furthermore, one end of the water quality monitoring pipe 109 is connected to a water outlet valve 112, and the other end of the water outlet valve 112 is connected to a flange at one end of the water outlet pipe 111.

[0028] Furthermore, an inlet valve 108 is installed and connected to the top of the outer end face of the inlet valve 118.

[0029] Furthermore, a water outlet valve 110 is installed and connected to the top of the outer end face of the water outlet valve 112.

[0030] Furthermore, a leak detector 107 is installed and connected to the top of the water inlet pipe 102, and a leak detector base 121 is provided at the bottom of the leak detector 107. A leak detector connector 122 is fixed at the bottom of the leak detector base 121, and the leak detector connector 122 is convenient to be installed and connected to the outer end face of the water inlet pipe 102.

[0031] Furthermore, the top of the leak detector 107 is equipped with a leak detector signal device 123 for signal transmission.

[0032] It should be further explained that the leak detector signal unit 123 uses GPRS or 4 / 5G data communication, and the leak detector 107 accurately locates the leak point through AI algorithms such as deep learning, transmits the leak status remotely, verifies the leak point through remote noise monitoring, reduces the false alarm rate, remotely calculates the leak point location, reduces the workload of on-site location, and can be flexibly connected to third-party systems.

[0033] It is worth further explaining that the leak detector 107 adopts a trenchless detection method, which does not require damaging the road surface. Combined with the smart platform, it can realize routine monitoring of the health status of the pipeline network, effectively reducing the cost of leak detection.

[0034] Furthermore, a power supply battery 124 is provided on one side of the component cavity 120, which provides power.

[0035] It should be further noted that the power supply battery 124 is a self-powered module, which supports the device to operate stably for a long time without external power supply, meeting the deployment needs of field or municipal pipeline network nodes.

[0036] Furthermore, a well casing 103 is fixedly installed on the top of the well body 101, and a sealing ring 105 is installed and connected on the top of the well casing 103. A load-bearing cover 104 is provided on the top of the sealing ring 105.

[0037] It should be further explained that the water quality analyzer 125 uses MEMS technology to miniaturize the sensor. Its electrode surface is coated with a polymer film, which can mitigate the impact of water flow changes on electrochemical reactions, extending the maintenance cycle to more than 6 months. Furthermore, it consumes no reagents and generates no waste liquid; the only consumable is the electrode cap, which can be replaced more than once a year. The pressure sensor 126 is used to monitor changes in pipeline pressure in real time, providing a basis for leakage analysis and scheduling decisions.

[0038] The operating procedure of this device is as follows: First, water from the water supply network enters the inlet pipe 102 from upstream, passes through the inlet pipe valve 118, the expansion pipe 117, the metering pipe 115, the water quality monitoring pipe 109, and the outlet pipe valve 112, before flowing out through the outlet pipe 111 to the downstream network. The expansion pipe 117 can be adjusted in length according to the on-site installation dimensions to compensate for pipe connection errors and ensure a precise connection between the device and the external network.

[0039] As water flows through metering pipe 115, the detection contact of meter 116 collects flow data in real time and transmits the flow signal to the processing unit inside meter 116. Simultaneously, pressure sensor 126, installed at the upper end of outlet pipe 111, monitors network pressure data in real time, and water quality analyzer 125 continuously monitors water quality parameters. The multi-parameter data collected by meter 116, pressure sensor 126, and water quality analyzer 125 are aggregated to the data acquisition module via wired or wireless means, and then uploaded to the management platform via remote communication module, enabling remote monitoring and intelligent scheduling.

[0040] When the device is in operation, the leak detector 107 continuously collects acoustic signals from the inlet pipe 102 and its surrounding pipe network. The built-in AI algorithm in the leak detector 107 analyzes the acoustic signals in real time, identifies abnormal noise characteristics, and determines whether a leak exists. When a suspected leak is detected, the leak detector signal unit 123 transmits the leak status, noise data, and preliminary location information to the management platform via GPRS or 4 / 5G network. The platform can verify the suspected leak through remote noise monitoring and further pinpoint the leak location using remote correlation calculations, reducing on-site location workload.

[0041] In terms of water quality monitoring, the water quality analyzer 125 uses MEMS technology to monitor multiple water quality parameters in real time, such as residual chlorine, turbidity, and pH value. When a water quality parameter exceeds a preset safety threshold, the system issues a water quality anomaly warning and automatically controls the water quality safety protection valve 113 to close, cutting off upstream water flow and preventing contaminated water from entering the downstream pipe network. Simultaneously, the anomaly information is reported to the management platform via remote communication, notifying maintenance personnel for timely handling.

[0042] In terms of power supply, the power supply battery 124 provides a stable power supply for all electrical equipment within the device. The power supply battery 124 adopts a self-powered design and has low-power management functions, enabling it to support long-term continuous operation of the device without external power supply, meeting the deployment needs of field or municipal pipeline network nodes.

[0043] In terms of structural protection, after the device is installed, the sealing ring 105 on the top of the well barrel 103 and the load-bearing cover 104 form a double sealing structure, which effectively prevents groundwater, surface water and soil impurities from seeping into the well body 101. The well body 101 is made of high-strength composite material HPCC in one piece, which has the characteristics of anti-rolling and anti-settlement. It can adapt to complex working conditions such as heavy road load and soil settlement, ensuring that the internal components are in a water-free, dust-free and harmful gas-free operating environment for a long time, ensuring stable operation of the equipment and extending its service life.

[0044] When on-site inspection and maintenance are required, maintenance personnel can open the load-bearing cover 104 and enter the component cavity 120 through the shaft 103. The component cavity 120 has a reasonable layout, with sufficient operating space reserved for each valve, instrument and testing equipment, which facilitates maintenance personnel to carry out daily inspections, parameter calibration and equipment replacement.

[0045] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. The scope of protection of the present invention should be determined by the scope of the claims.
