[0030] During the use of the material cleaning mechanism 5, when impurities and materials are accumulated inside the drainage bucket 4 and need to be cleaned, the servo motor 514 is started, and the output end of the servo motor 514 drives the spur gear 515 to rotate, and at the same time drives the gear ring 513 and the rotating ring 511 thereon to rotate, and synchronously drives the fixed block and the fixed rod 518 thereon to rotate, and at the same time drives the triangular discharge block 516 to rotate, and the triangular discharge block 516 discharges the materials accumulated on the top of the fixed cover 512 to one side of the scraper plate 517, and the scraper plate 517 is used to perform rotational scraping.

[0032] When structural water leaks into the drainage bucket 4, it is then filtered by the filter cartridge 53 and enters the metering box 1 through the connecting pipe for collection. As the water is collected, the water level inside the metering box 1 continues to rise. When it reaches the upper limit switch position, the one-way solenoid valve 8 automatically opens, and the water in the metering box 1 is discharged from the outlet pipe 6. The electronic meter 7 measures the drainage flow. When the water level after drainage reaches the lower limit switch, the one-way solenoid valve 8 is closed and drainage is stopped. The electronic counting module 14 records the number of times the one-way solenoid valve 8 is opened, thereby recording the number of drainages, and the electronic meter 7 measures the flow of each drainage in milliliters. By repeatedly recording the leakage water capacity and the number of discharges, the daily leakage, weekly leakage, monthly leakage, and The quarterly leakage volume, annual leakage volume and change trend, flow data and drainage frequency data are connected to the optoelectronic communication module 17 through the exchange interface, and the A / D conversion module 16 is used to convert the analog data, and then transmitted to the RTU area control module 18 through the optical fiber, and then transmitted to the server 10 through the RTU area control module 18 using the tunnel network system. The database 11 stores the data, and the monitoring platform 12 is used to display the monitoring data. It can display the water leakage monitoring distribution map of the entire tunnel, and can also display the total or real-time data of each metering bucket, historical data, alarm data and change curve. The database 11 can be used for retrieval, statistics and analysis, and four different colors of blue, yellow, orange and red can be used to warn different levels of alarms and intuitively display them on the monitoring platform 12.

[0033] It should be noted that when using this tunnel leakage metering and monitoring device and monitoring and analysis system, first use bolts to fix the equipment to the designated position of the tunnel leakage. The leaked water flows into the drainage bucket 4, and then enters the metering box 1 through the connecting pipe after being filtered by the filter cartridge 53 for collection. The impurities and dust on the filter cartridge 53 and the drainage bucket 4 are cleaned and collected by the material cleaning mechanism 5, without manual cleaning, saving time and effort. The water level inside the metering box 1 continues to rise. When it reaches the upper limit switch position, the one-way solenoid valve 8 automatically opens, and the water in the metering box 1 is discharged from the outlet pipe 6. The electronic meter 7 measures the drainage flow. When the water level after drainage reaches the lower limit switch, the one-way solenoid valve 8 is closed, and the electronic counting module 14 records the number of times the one-way solenoid valve 8 is opened. The electronic meter 7 measures the flow of each drainage, and the recorded data is transmitted to the monitoring platform 12 for display, thereby realizing real-time monitoring of the leakage situation.
