Description

Technical Field

[0001] This invention relates to the field of tunnel segment maintenance technology, specifically to a special testing device for tunnel segment water curing tanks. Background Technology

[0002] Currently, the tunnel segments are being maintained in a hydroponic tank. Changes in water level and pH levels can only be partially digitized, relying on traditional sensors to detect changes and then manual adjustments are made.

[0003] On the one hand, the aforementioned operational procedures still require manual labor. Given the large area of ​​the processing site, manual intervention would inevitably increase the workload of personnel and raise labor costs for production companies. Furthermore, during the water curing process, concrete debris and impurities easily detach from the surface of the tunnel segments. These impurities can adhere to the surface of the detection sensors or clog the detection pipelines, leading to decreased sensor accuracy, frequent equipment malfunctions, and further affecting the accuracy and timeliness of maintenance parameter control. Simultaneously, traditional water curing tanks lack effective water purification and circulation mechanisms, resulting in insufficient dissolved oxygen content, impurity accumulation, accelerated pH imbalance, and reduced curing effectiveness.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Please see Figures 1-8 This invention provides a technical solution: a special detection device for a water-supported tube segment.

[0035] It includes a testing box 1, and the inside of the testing box 1 is equipped with a pH value testing component 3. The pH value testing component 3 includes a pH material storage box 301 that is fixedly installed on the inner wall of the testing box 1.

[0036] Please see Figures 1 to 4 A material delivery pipe 302 is fixedly embedded on the lower surface of the pH material storage box 301, and a delivery pump 303 is fixedly installed at the bottom of the pH material storage box 301. The input end of the delivery pump 303 is fixedly connected to the output end of the material delivery pipe 302, and a pH detection pipe 304 is fixedly connected to the output end of the delivery pump 303. The end of the pH detection pipe 304 away from the delivery pump 303 extends to the outside of the detection box 1 and is fixedly connected to a pH value sensor 309. The input end of the pH value sensor 309 is fixedly connected to a detection water pipe 305.

[0037] A liquid level sensor 306 is fixedly connected to the inner wall of the pH material storage box 301. The liquid level sensor 306 is used to monitor the liquid level of the pH material inside the pH material storage box 301. An automatic pH material adding tube 307 is fixedly embedded on the upper surface of the pH material storage box 301. The input end of the automatic pH material adding tube 307 extends to the outside of the detection box 1, and a second electromagnetic switch valve 308 is fixedly installed on the surface of the automatic pH material adding tube 307.

[0038] Please see Figures 3 to 6 A liquid level sensor 306 is fixedly connected to the inner wall of the pH material storage box 301. The liquid level sensor 306 is used to monitor the liquid level of the pH material inside the pH material storage box 301. An automatic pH material adding tube 307 is fixedly embedded on the upper surface of the pH material storage box 301. The input end of the automatic pH material adding tube 307 extends to the outside of the detection box 1, and a second electromagnetic switch valve 308 is fixedly installed on the surface of the automatic pH material adding tube 307.

[0039] It is worth noting that the isolation between the pH material storage box 301 and the water in the testing box 1 prevents premature reaction between the pH material and the water, ensuring adjustment accuracy. The testing water pipe 305 extends into the collecting pipe 517 to collect test samples. Since the water in the collecting pipe 517 is filtered and purified by the water quality treatment component 5, the impact of impurities on the detection accuracy of the pH sensor 309 is reduced. The linkage between the liquid level sensor 306 and the second electromagnetic switch valve 308 enables automatic replenishment of the pH material, eliminating the need for regular manual addition, reducing manual maintenance costs, and preventing water quality control interruptions due to insufficient pH material, thus ensuring the stability of the pipe segment maintenance environment.

[0040] Please see Figures 2 to 7 The water level detection component 4 includes a water supply pipe 401 fixedly connected inside the detection box 1. A three-way valve 402 is fixedly connected to the bottom end of the water supply pipe 401. A water supply pipe 403 is fixedly connected to one port of the three-way valve 402, and a water level detection pipe 404 is fixedly connected to the other port of the three-way valve 402.

[0041] A third electromagnetic switch valve 407 is fixedly installed on the surface of the water supply pipe 401, and the input end of the water supply pipe 401 extends upward to the outside of the detection box 1. The water inlet end of the water supply pipe 401 is connected to the external water supply pipe. A first switching valve 408 is fixedly connected to the surface of the water supply pipe 403, and a second switching valve 409 is fixedly connected to the surface of the water level detection pipe 404.

[0042] It is worth noting that the water level detection component 4 adopts an indirect detection-direct water replenishment design. The water level in the collection pipe 517 indirectly reflects the water level in the detection box 1, avoiding direct contact between the detection sensor and the segment maintenance area. This reduces the impact damage to the sensor caused by falling debris from the segment and extends the service life of the float-type water level sensor 405. The first switching valve 408 and the second switching valve 409 can flexibly switch between water replenishment and detection modes according to maintenance needs. For example, when the segment is initially placed in the detection box 1, the first switching valve 408 can be opened to increase the water replenishment volume and quickly reach the preset water level. During normal maintenance, the first switching valve 408 is closed, and the water level is monitored in real time through the water level detection pipe 404 to ensure water level stability. The closed-loop control of the third electromagnetic switch valve 407 and the float-type water level sensor 405 realizes the full automation of the water replenishment process. There is no need for manual monitoring of the water level, which reduces the intensity of manual labor and avoids the problem of excessive or insufficient water replenishment during manual replenishment, providing a stable water environment for segment maintenance.

[0043] Please see Figures 3 to 8The water treatment component 5 includes a support frame 501 fixedly installed on the side of the testing box 1.

The cleaning screen 510 is cylindrical, and a limiting base plate 511 is fixedly connected to the bottom end of the cleaning screen 510. The position of the cleaning screen 510 corresponds to the rotating shaft 504, and the rotating shaft 504 is located inside the cleaning screen 510. A rectangular guide hole 507 is located above the limiting base plate 511.

[0045] A ventilation pipe 512 is fixedly connected to the top of the treatment cylinder 503. The air inlet end of the ventilation pipe 512 is fixedly connected to the output end of the ventilation pump 502. A conical jet pipe 513 is fixedly connected to the bottom end of the ventilation pipe 512. The bottom end of the conical jet pipe 513 extends into the interior of the treatment cylinder 503, and the output end of the conical jet pipe 513 corresponds to the position of the rotating impeller 505.

[0046] Please see Figures 4 to 7 The bottom end of the guide pipe 506 extends to the bottom of the limiting base plate 511 and is rotatably connected to the inner bottom wall of the processing cylinder 503. A first electromagnetic switch valve 518 is fixedly installed on the bottom surface of the guide pipe 506. Two movable supports 514 are symmetrically fixedly connected to the surface of the guide pipe 506. Rotating cleaning plates 515 are fixedly connected to the upper surface of the two movable supports 514. Sponge scrapers 516 are fixedly connected to the opposite surfaces of the two rotating cleaning plates 515. The sponge scrapers 516 overlap with the surface of the impurity removal screen 510.

[0047] A converging pipe 517 is fixedly installed at the bottom of the treatment cylinder 503. The top end of the converging pipe 517 extends into the interior of the treatment cylinder 503 and is rotatably connected to the bottom end of the guide pipe 506. A float-type water level sensor 405 is fixedly connected to the end of the water level detection pipe 404 away from the three-way valve 402. An L-shaped water pipe 406 is fixedly connected to the bottom water inlet end of the float-type water level sensor 405. The end of the L-shaped water pipe 406 away from the float-type water level sensor 405 extends into the interior of the converging pipe 517. The input end of the detection water pipe 305 extends into the interior of the converging pipe 517.

[0048] It should be noted that a controller is fixedly installed on the side of the detection box 1. The pH value detection component 3, the water level detection component 4, and the water quality treatment component 5 are linked and controlled by the circuit and the controller.

[0049] It is worth noting that the water treatment component 5, through its integrated design of dual filtration, circulating oxygenation, and automatic cleaning, improves the cleanliness and dissolved oxygen content of the water in the testing chamber 1. The grid columns 509 of the arc-shaped water inlet 508 and the impurity removal screen 510 form a dual filtration system, which can intercept impurities of different particle sizes, preventing impurities from entering the testing pipeline or adhering to the surface of the pipe segments, thus affecting the maintenance quality and testing accuracy of the pipe segments. The ventilation air pump 502 drives the rotating impeller 505 to rotate through the conical jet pipe 513. On the one hand, this drives the guide pipe 506 and the rotating cleaning plate 515 to rotate, and the sponge scraper 516 automatically cleans the impurities on the surface of the impurity removal screen 510, preventing the screen from clogging. This eliminates the need for manual disassembly and cleaning, reducing maintenance difficulty. On the other hand, the air delivered by the ventilation air pump 502 enters the water body through the conical jet pipe 513, making full contact with the water droplets generated by the rotating impeller 505, significantly increasing the dissolved oxygen content of the water body, reducing the carbon dioxide concentration, indirectly stabilizing the pH value of the water body, and reducing the amount of pH adjustment materials used.

[0050] Working principle: First, several detection boxes 1 are installed and deployed on the outside of the pipe segment hydroponic tank. Then, the pH detection component 3, including the pH sensor 309 and the float-type water level sensor 405, and the water level detection component 4 are placed into the hydroponic tank.

[0051] The pH sensor 309 continuously collects water samples from the collection pipe 517 through the detection water pipe 305, detects the pH value in real time, and transmits it to the controller. When the detected pH value is lower than the preset threshold, the controller starts the delivery pump 303. The pH adjusting material in the pH material storage box 301 is injected into the detection box 1 through the material delivery pipe 302, the delivery pump 303, and the pH detection pipe 304 to adjust the pH value of the water. When the pH sensor 309 detects that the value has reached the preset range, the controller sends a signal and the delivery pump 303 stops working. If the material level in the pH material storage box 301 is lower than the preset value, the level sensor 306 triggers a signal, the second electromagnetic switch valve 308 opens, and the external material is automatically replenished until the level reaches the target and then it closes.

[0052] Simultaneously, the controller can start the ventilation air pump 502. The ventilation air pump 502 pressurizes the outside air and delivers it to the conical jet pipe 513 through the ventilation air pipe 512. The conical jet pipe 513 concentrates the airflow and sprays it onto the rotating impeller 505, generating driving force to drive the rotating impeller 505 to rotate. The rotating impeller 505 drives the rotating shaft 504 and the guide pipe 506 to rotate synchronously. The movable bracket 514 on the surface of the guide pipe 506 drives the rotating cleaning plate 515 and the sponge scraper 516 to rotate. The sponge scraper 516 continuously scrapes away the impurities attached to the surface of the impurity removal screen 510. Under the suction of the rotating impeller 505, the water in the detection box 1 enters the treatment cylinder 503 through the arc-shaped water inlet 508. After being filtered by the grid column 509 and the impurity removal screen 510, it mixes with the airflow for oxygenation and then flows into the converging pipe 517 through the guide pipe 506, forming a water circulation.

[0053] The float-type water level sensor 405 continuously monitors the water level in the collecting pipe 517 through the L-shaped water pipe 406. When the water level drops to a preset minimum value due to evaporation or leakage during the pipe segment maintenance process, the sensor will detect the water level.

[0054] The float-type water level sensor 405 sends a signal to the controller, the third electromagnetic switch valve 407 opens, and the external water supply enters the detection box 1 through the water replenishment pipe 401, the three-way valve 402 and the water supply pipe 403; when the water level rises to the preset maximum value, the float-type water level sensor 405 sends a stop signal, the third electromagnetic switch valve 407 closes, and the automatic water replenishment is completed.
