Abstract
Description
Technical Field
[0001] This utility model belongs to the field of tunnel leakage monitoring technology, specifically relating to a tunnel leakage water metering and monitoring device. Background Technology
[0002] Metered monitoring of tunnel water leakage is a crucial step in ensuring the structural safety and durability of tunnels. It is mainly used for monitoring structural water leakage in facilities such as river-crossing tunnels, underground tunnels, subways, underground utility tunnels, and railway culverts.
[0003] Current methods generally involve manual on-site inspections or monitoring devices. On-site inspections are time-consuming and labor-intensive, while existing monitoring devices require the collection of leaking rainwater to achieve the purpose of detection. However, during collection, impurities and dust also fall into the collection hopper, causing blockage and reducing the accuracy of the detection. At the same time, existing monitoring equipment is difficult to accurately measure, monitor, and analyze structural leaks. Utility Model Content

[0021] Example
[0022] Please see Figure 1 and Figure 2 A tunnel seepage water metering and monitoring device includes a metering box 1, a measuring cylinder on the front side of the metering box 1, two support rods 2 fixedly connected symmetrically on the top of the metering box 1, a diversion bucket 4 on the top of the two support rods 2, a material cleaning mechanism 5 on the diversion bucket 4, a protective box 9 at the center of the bottom of the metering box 1, a water outlet pipe 6 fixedly installed on the right side of the bottom of the metering box 1, a one-way solenoid valve 8 in the middle of the water outlet pipe 6, and an electronic meter 7 at the bottom of the water outlet pipe 6, an upper limit switch on the top left side of the metering box 1, a lower limit switch on the bottom left side of the metering box 1, and two L-shaped fixing plates 3 fixedly installed symmetrically on the rear side of the top of the diversion bucket 4, with mounting holes on both L-shaped fixing plates 3.
[0023] In use, the metering box 1 and measuring cylinder are used to measure the water that leaks into them, the diversion bucket 4 is used to divert and collect the leaked water, the material cleaning mechanism 5 is used to scrape and clean the debris in the diversion bucket 4, the water outlet pipe 6 is used to drain water, the electronic meter 7 is used to measure the discharge volume, and the L-shaped fixing plate 3 is used for the fixed installation of the equipment.
[0024] Please see Figure 2 and Figure 3 The material cleaning mechanism 5 includes a scraping component 51, a waste collection component 52, and a filter cartridge 53. The filter cartridge 53 is fixedly inserted through the center of the bottom of the diversion hopper 4. After the bottom of the filter cartridge 53 passes through the diversion hopper 4, a connecting pipe is fixedly connected to it, and the connecting pipe is connected to the inside of the metering box 1. The scraping component 51 and the waste collection component 52 are both installed on the diversion hopper 4.
[0025] Please see Figure 2 and Figure 3The scraping assembly 51 includes a servo motor 514 fixedly connected to the bottom left side of the diversion hopper 4. The output end of the servo motor 514 rotates through the bottom of the diversion hopper 4 and is fixedly sleeved with a spur gear 515. A fixed cover 512 is fixedly installed on the bottom surface inside the diversion hopper 4. A toothed ring 513 that meshes with the spur gear 515 is rotatably connected to the bottom surface inside the fixed cover 512. A rotating ring 511 is fixedly installed on the top of the toothed ring 513. The rotating ring 511 rotates through the top of the fixed cover 512, and a sealing ring is provided between the rotating ring 511 and the fixed cover 512. A fixed block is fixedly installed on the top of the rotating ring 511. A fixed rod 518 is fixedly installed on the top of the fixed block. A scraper plate 517 for scraping and cleaning the inside of the diversion hopper 4 is fixedly connected to the bottom of the fixed rod 518. A triangular discharge block 516 for discharging impurities remaining on the top of the fixed cover 512 is fixedly installed on the rear side of the fixed rod 518.
[0026] Please see Figure 2 , Figure 4 and Figure 5 The waste collection assembly 52 includes an L-shaped fixing plate 525 fixedly connected to the rear side of the bottom of the diversion hopper 4. The L-shaped fixing plate 525 includes a horizontal section and a vertical section. A hydraulic cylinder 523 is fixedly installed at the top of the horizontal section. A fixing head 521 is fixedly installed at the output end of the hydraulic cylinder 523. A sealing door 522 is fixedly installed at the top of the fixing head 521. A material leakage port is opened on the rear side of the diversion hopper 4, and the sealing door 522 is movably inserted into the inside of the material leakage port. A sealing ring is provided between the material leakage port and the sealing door 522. A collection box 524 is fixedly connected to the rear side of the bottom of the diversion hopper 4 by screws. The collection box 524 is sleeved on the outside of the L-shaped fixing plate 525.
[0027] During use, when impurities and materials accumulate inside the diversion hopper 4 and need cleaning, the servo motor 514 is activated. The output of the servo motor 514 drives the spur gear 515 to rotate, which in turn drives the gear ring 513 and its rotating ring 511 to rotate. Simultaneously, the fixed block and its fixed rod 518 rotate, and the triangular discharge block 516 rotates. The triangular discharge block 516 discharges the material accumulated on the top of the fixed cover 512 to one side of the scraper plate 517, where it is scraped off by rotation. At this time, the hydraulic cylinder 523 is activated, and the output of the hydraulic cylinder 523 retracts, simultaneously driving the fixed head 521 and its sealing door 522 to move downward, loosening the seal between the sealing door 522 and the leakage port. The impurities and materials are then discharged from the leakage port into the collection box 524 for collection. This achieves automatic sludge removal inside the diversion hopper 4, avoiding blockages and eliminating the need for manual cleaning, saving time and effort.
[0028] It should be noted that, in use, this tunnel leakage water metering and monitoring device first uses bolts to fix the equipment to the designated location of the tunnel leakage. The leaking water flows into the diversion bucket 4, then is filtered by the filter cartridge 53 and enters the metering box 1 through the connecting pipe for collection. The material cleaning mechanism 5 cleans and collects impurities and dust on the filter cartridge 53 and the diversion bucket 4, eliminating the need for manual cleaning and saving time and effort. The water level inside the metering box 1 rises continuously. 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 rate. When the water level after drainage reaches the lower limit switch, the one-way solenoid valve 8 closes. The electronic counting module 14 records the number of times the one-way solenoid valve 8 opens, and the electronic meter 7 measures the flow rate of each drainage.
[0029] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
